Unfortunately, this study cannot be evaluated since the documentation of the actual laser parameters is poor. The only information given about these essential facts is "The LILT device had a wavelength of 905 nm and an average power of 0-60 mW. All LILT treatments were for 5 min per site." Which output was actually used? Pulse repetition rate? Dose? Power density?

This paper describes an example of what I have been calling an equivalence class of transcriptional enhancers. This is compared with other such sets in this short collection of slides: How to best approach transcriptional enhancers?. Albert Erives. figshare. http://dx.doi.org/10.6084/m9.figshare.829049

What is not well-described in this paper is how their common site organization was found based on a subset of "specialized sites" within homotypic site clusters. A specialized site is defined mathematically as a sequence matching a binding motif descriptor that identifies a single unique site within each member of a set of homotypic binding site clusters. In other words, specialized sites are identifiable and distinguishable by the existence of any motif that matches them as single components of each homotypic site cluster belonging to a set of mechanistically-equivalent enhancers. A motif that describes more than a single site in each cluster is therefore not a specialized motif. Okay, that's not the easiest thing to get across even today, but this method led to the identification of the so-called D-alpha site, which turned out to be a Su(H) binding site that had evolved over a relic Dorsal binding site, and the so-called D-beta site, which turned out to be the closest Dorsal-binding-like site to the Twist site, the distance to which we later found to encode a large component of the response to the Dorsal morphogen gradient. (See here Crocker J, 2008 and here Crocker J, 2010.) For me, the major significance of this method is that it works well in distinguishing functional sites from relic (pseudogenized), fast-evolving sequences.

It is well established that in Japan, where only 1 in 5 children received varicella vaccination, that those vaccinated maintained protective immunity for 20 years. This was largely due to the vacinees' receiving exogenous exposures to children with natural or wild-type varicella that boosted cell-mediated immunity to varicella zoster virus. During the majority of the study by Kuter et al., varicella vaccine receipients were likewise being boosted through exposure to individuals with wild-type varicella--especially during annual epidemics of varicella. This had the effect of artifically elevating vaccine effectiveness because of the shedding of varicella zoster virus in the community. In communities with widespread varicella vaccination, once oppotunities for exogenous boosts became rare, single-dose varicella vaccination efficacy declined to less than 50% five years after vaccination.Goldman GS, 2005

Dr. Schwartz dates the first description of hemoglobinuria (as black urine) to the 13th century AD (1).

About 400 BC, however, Hippocrates described urinary quantity, color, consistency, or sediment in 41 of 42 case reports in his Book of Epidemics (2). Twelve case reports mention black urine, a frequency so high that one wonders if glucose-6-phosphate dehydrogenase deficiency (3) and/or fava bean ingestion could have predisposed this population to hemolysis.

Inspection of the urine was important in ancient Greek medicine, but has been recently dismissed as “mostly nonsense” (4). Yet, the approach taken by Hippocrates was remarkably modern. In several patients having pigmented urine, Hippocrates checked for the appearance of a sediment after allowing the urine to sit — a maneuver that would have allowed him to distinguish hematuria from hemoglobinuria and myoglobinuria.

Such insights from Hippocrates are not surprising. As Garrison has remarked, “All that a man of genius could do for internal medicine, with no other instrument of precision than his own open mind and keen senses, he accomplished” (5).

The authors have done an outstanding and excellent study. However, they seem to have failed to notice here that, in Table 2, their reported male fraction of SIDS (0.612) in 260 cases (excluding matched sets) is identical to the male fraction of SIDS reported by Mage and Donner (PMID 9076695) of 41,238 male and 26,140 female in 36 SIDS data sets giving a male fraction of 0.6120. This is important to note because the consistancy of the male fraction of SIDS throughout time and among various countries supports a recessive X-linkage of susceptibility to SIDS that seems to be ignored inspite of the early conclusion of Naeye et al. in PMID 5129451, that male susceptibility to infant death "must" be X-linked.

A CFS study which raises questions about the use of the Role Emotional (RE) subscale of the SF-36 to define CFS

(This was originally posted here: http://www.biomedcentral.com/1472-6963/3/25/comments but the formatting has been lost and some people may read the paper on PubMed Central)

As I mentioned in the previous comment, this paper recommends, amongst other questionnaires, the use of the SF-36 questionnaire but does not specify which subscales should be used.

One group of researchers[1] have decided to use the physical function, role physical, social function and role emotional subscales of the SF-36 to define disability, with a low score on just one of these subscales being sufficient to satisfy the criteria (i.e. there didn't need to be more than one low scores).

Since then, this definition has gone on to be used in numerous papers (such as [2-5]) as the CDC are using it as the definition they're using for their CFS studies in the US, and they probably have the largest CFS research program in the world. It was used to give the prevalence rate of 2.54% for CFS in the adult population[6]. Most recently, it was used to investigate the prevalence of the reporting of childhoold trauma in this cohort[7].

A study by Fulcher and White (2000)[8] raises questions about the use of the Role Emotional (RE) subscale of the SF-36 to select patients with CFS. The study involved 66 patients with CFS without a current psychiatric disorder, 30 healthy but sedentary controls, and 15 patients with a current major depressive disorder.

It found, amongst other things, that "the two patient groups were significantly more incapacitated than the sedentary controls on all SF-36 measures (p<0.001), except that the patients with CFS were not significantly different in emotional or mental function." Also, "the depressed subjects were significantly more incapacitated in emotional and mental functioning than the patients with CFS p<0.001)."

These results suggest that low scores on the emotional and mental functioning subscales of the SF-36 do not seem to be an intrinsic part of CFS (if they're found, they could be related to comorbid psychiatric issues). They also points out the risks of using the RE subscale alone [especially given CFS shares some characteristics with depression and so some people with depression (but not CFS) could potentially score the required 25 points on the Symptom Inventory] i.e. one could inadvertently include some people who have depression but not CFS, as CFS patients.

Which subscales of the SF-36 should be used? Results from a study in Fibromyalgia patients

(This was originally posted here: http://www.biomedcentral.com/1472-6963/3/25/comments but the formatting has been lost and some people may read the paper on PubMed Central)

This paper recommends, amongst other questionnaires, the use of the SF-36 questionnaire. But which subscales should be used? One group of researchers[1] decided to use the physical function, role physical, social function and role emotional subscales of the SF-36 to define disability, with a low score on just one of these subscales being sufficient to satisfy the criteria (i.e. there didn't need to be more than one low scores). Since then, this definition[1] has gone on to be used in numerous papers (for example, 2-5).

But is this a good way of using the SF-36 given the Fukuda definition for CFS[6] requires that there be a "substantial reduction in previous levels of occupational, educational, social, or personal activities".

Fibromyalgia patients share many similarities with CFS patients and many researchers use CFS and FMS patients together in their studies (for example [7-10]).

One study[11] recently assessed Fibromyalgia Syndrome (FS) patients using the SF-36 questionnaire. It found that patients could be broken down into two groups using the SF-36 subscales looking at mental well-being (social functioning, role limitation due to emotional health problems, and mental health). "One group demonstrated psychological dysfunction, whereas the other showed normal psychological scores. Physical well-being scores (physical functioning, role limitation due to physical health problems, bodily pain, general health, and vitality) did not differ between FS patients but were altogether below the normal range."

If this was found to be the same in other populations, it would suggest that perhaps including patients who solely have low scores on subscales assessing mental well-being such as the role emotional and social functioning subscales of SF-36, which is all the CFS definition prepared by Reeves[1] requires, would select a group of people with psychological dysfunction but not necessarily greater physical disability.

Chk1 is an important DNA damage checkpoint protein kinase. Biochemical evidence suggests that the sites most vigorously phosphorylated by the Chk1/2 kinases match or are close to the pattern (LF)xRxx(pST)(LF). See, for example, these articles (PMID: 10648819; 10761933; 11821419; 12711320). If only one of the three specificity determining positions are lost, the kinases may still phosphorylate, but at reduced activity. This gradation in activity might have biological significance and also means that it is difficult to define motif patterns for Chk kinase substrate sites. Currently we are trying to do this for the ELM protein motif resource (http://elm.eu.org/).

In the paper that I would like to comment on here, the reported phosphorylation site at Ser47 of p73 - VgGtd(pS)S - lacks all of the strong specificity determinants (capitalised positions). It has been confounding our attempt to define a Chk phosphorylation site pattern for ELM. However, based on a close examination of the figures in the paper, we have now decided to exclude this p73 site from further consideration.

Dear Reader, This is where it all started, when I moved from Mexico to the U.S., at the Baylor College of Medicine (BCM), within the Texas Medical Center; we had Perilipin knock out mice able to eat as much fat and carbohydrates as they wanted, never getting obese, but remaining slender, so, we were able to determine the basic biochemical profile of these organisms, which had over expressed the pathways of Beta Oxidation, and of the Respiratory Chain, and also of the Krebs Cycle, while they had down regulated the pathways of the Unsaturation of Fats, and of the production of Cholesterol.

On 2013 Nov 24, John Sotos commented:

The discussion of how to manage Mrs. P, a 60 year old woman with atrial fibrillation (1), nicely reprised Sir William Osler’s 1907 advice: “Too much stress should not be laid upon arrhythmia per se in the absence of organic disease” (2).

As presented, however, Mrs. P’s evaluation did not adequately exclude organic disease: neither her body mass index nor a general description of her habitus was provided. Although her physicians obviously had access to this information, its omission from the case record suggests that an emerging correlate of atrial fibrillation, obstructive sleep apnea (OSA), was not considered as a potential exacerbating factor in her illness.

The prevalence of OSA in American adults is estimated as 20%, most of it undiagnosed, and most of it related to obesity (3). Hypothyroidism and alcohol ingestion, both of which Mrs. P had, are two of several additional risk factors.

As recently reviewed in JAMA, the role of OSA in cardiac disorders is receiving increasing attention, in part because OSA “frequently coexists undiagnosed in patients with cardiovascular disease” (4). Several physiological mechanisms plausibly link OSA and atrial fibrillation (4), but few studies have examined their clinical links. Of highest relevance for Mrs. P, however, Kanagala et al (5) found that untreated sleep apnea doubles the likelihood of atrial fibrillation recurring within 12 months of cardioversion, when compared to OSA patients receiving positive pressure treatment.

The effectiveness, and, therefore, cost-effectiveness, of testing for OSA in patients with atrial fibrillation is unknown. However, given that OSA is itself common, serious, and treatable, a case can be made for testing patients such as Mrs. P for sleep apnea, especially if they are obese, before consigning them to a lifetime of perhaps unnecessary warfarin therapy. Certainly a stronger case can be made for taking a sleep history in all patients with atrial fibrillation.

This is to be expected with ad hoc models, but at least it shows that the authors were sincere in their attempts, though this doesn't excue sloppy reasoning at that level. They also seem inclined to continue in the same style ("adding components" to the failed models rather than rethinking their ideas). The transparency-requiring low-level channel assumptions are apparently untouchable, non-negotiable. I know it's a cliche, but it's a recipe for misguided Ptolemaic solar system-level complexity, as the authors demonstrate.

The article is "Probed-sinewave paradigm: a test of models of light-adaptation dynamics. Hood DC1, Graham N, von Wiegand TE, Chase VM" and its authors frankly acknowledge the utter failure of their hypothesis:

"Our purpose here was to explore a relatively unused paradigm, the probed-sinewave paradigm, as a vehicle for distinguishing among candidate models of light adaptation. The paradigm produced orderly data with clear features. The candidate light-adaptation models, however, were unable to predict these features and our attempts to rescue them by changing parameter values and the decision rule were unsuccessful. While it is plausible that other modifications would produce predictions closer to the data, it is hard to believe these models can be rescued without adding additional components. For discussion, we divide these possible components into those that seem to require an additional channel vs those components that can be added to the single-channel of the models in Fig. 6."

"While this discussion suggests a number of plausible directions for future work, it is not at all clear which direction or model will ultimately prove most successful. We started with a paradigm we thought would be a strong test of existing models; the test turned out to be even stronger than we expected."

So pretty much starting at zero, after all that. Performing a strong test was the right move. The wrong move was not realizing, on the basis of solid reasoning, that the theoretical foundation of the model was flimsy and that models with such flimsy foundations are bound to fail unless you are extraordinarily lucky.

Let me add that all models eventually fail, but it is the case of well-reasoned ones that these failures are informative, and necessary.

Part two: Popper has discussed traditions such as those described and illustrated above, and concluded that they are not the kind of traditions that endow scientific activity with its progressive character. He suggested that we choose not to immunize our hypotheses with the tactics discussed above, e.g. leaving problems for the future and piling ad hoc model on top of ad hoc model, and having tolerance for logical inconsistencies. But that's a harder way than the vagueness, sloppiness and special pleading masked in technical complexity that has come to dominate contemporary vision science and in fact almost the whole of science today.

On 2016 Jul 23, Lydia Maniatis commented:

This article is illustrative of the degradation of theory and practice in vision science. The article is not new (but compare with, e.g. Graham, 2011), but many of its assumptions and the style of argument - tolerance for layers upon layers of uncorroborated assumptions and inadequate, ad hoc models - are still very current and underpin a broad swath of contemporary (arguably pseudoscientific) activity. Below are quotes from the article and my comments.

The abstract: "Light adaptation has been studied using both aperiodic and periodic stimuli. Two well-documented phenomena are described: the background-onset effect (from an aperiodic-stimulus tradition) and high-temporal-frequency linearity (from the periodic-stimulus tradition). These phenomena have been explained within two different theoretical frameworks. Here we briefly review those frameworks. We then show that the models developed to predict the phenomenon from one tradition cannot predict the phenomenon from the other tradition, but that the models from the two traditions can be merged into a class of models that predicts both phenomena."

Comment: One wonders whether the merger was ultimately successful, and whether falsifying phenomena from yet other traditions could be merged with these two, to expand the ever-expanding ad hoc circle of tradition.

Note that the piecemeal "merger" philosophy expressed by Graham and Hood seems to preclude falsification. Falsifying phenomena from another "tradition" simply lead to the summing of individual ad hoc models into a compound ad hoc model, and so on. The complexity but not the information content of the models will thus increase. (This will also likely produce internal inconsistencies that not be noticed because they will not be looked for.) The question of whether these models correspond with the facts that they are supposedly trying to explain never really arises.

All this can be garnered from the abstract: If anything, the text is even worse.

"None of the parts of the merged models, however, is necessarily correct in detail. Many modifications or substitutes would clearly work just as well at this qualitative level. …Also, one could certainly expand the model to include more parts. …Similarly, the initial gain-controlling process might be composed of several processes having somewhat different properties"

Comment: The models are arbitrary, ad hoc, incomplete on their own terms, and there is no rational criterion for choosing among an infinite number of alternatives.

"No attempt was made to fine-tune either model to predict all the details in any one set of psychophysical data…much less in all the other psychophysical results that such a model might bear on…To attempt such a project in the future might be worthwhile...particularly if the experimental results were all collected on the same subjects..."

Comment: In other words, because the models are ad hoc they may only explain the results to which they were tailored. It may (or may not??) be worth checking to see whether this is the case. I.e. testing models for correspondence with the phenomena is optional. The effects in question are too fragile and too little understood to be tested across subjects with varying methods.

"The more vaguely-stated possibility suggested by this observation, however, is that any decision rule of the kind considered here may be in principle inadequate for the suprathreshold-discrimination case. It may be impossible to explain suprathreshold discriminations without more explicit modeling of higher-level of higher-level visual processes than is necessary to explain detection (where detection is a discrimination between a stimulus and a neutral stimulus.)... Thus a simple decision rule may be suitable in the detection case simply because all the higher-level processes are reduced to such simple action THAT THEY BECOME TRANSPARENT." [caps mine].

Comment: The idea that there are certain experimental conditions in which the conscious percept consists in the reading off of the activity of "low-level" neurons (as though there was a direct qualitative correspondence between neural firing and seeing, e.g., a blank screen!) is patently absurd and has been criticized in depth and from different angles by Teller (1984).

Pretending that we take it seriously, we could refute it by noting that the presumably simplest of all stimuli - a white surface free of any imperfections - produces the perception of a three-dimensional fog. Other experiments have also shown that organizational processes are engaged even at threshold conditions, and that, indeed, they influence thresholds.

The "transparency theory" is repeated by Graham (2011) in an article in Vision Research: "It is as if the near-threshold experiments made all higher levels of visual processing transparent, therefore allowing the properties of the low-level analyzers to be seen."

This casually proposed "transparency" theory of near-threshold stimulation is apparently the basis of the widespread belief in spatial frequency channels and the extraordinary elaboration of associated assumptions. Without the transparency theory, it is not clear that even cherry-picked evidence can support this popular field of research. (If you've ever wondered at the widespread use of "Gabor patches" in vision research, this is the root cause - they are considered elemental due to the transparency theory-supported low-level neuron spatial frequency sensitivity hypothesis. I suspect many of the people using then don't even know why).

Graham and Hood (1992) also go into a little finer detail about the putative basis of transparency: " In the suprathreshold discrimination case, the observer is trying to discriminate between two sets of neural responses…both of which sets contain many non-baseline responses. In the detection case…the observer is simply trying to detect some non-baseline responses in either set (since that is the set most likely to be the non-blank stimulus). Thus a simple decision rule may be suitable in the detection case simply because all the higher-level processes are reduced to such simple action that they become transparent."

Comment: The suggestion that investigators are managing to set their low-level visual neurons at baseline at the start of experiments also seems implausible. I certainly don't think this has been explicitly discussed from the point of view of method. "However, at this moment in time, we seem to be able to explain background onset with a subtractive process…Thus, we can just leave as a marker for the future – should troubles in fully explaining the data arise – the possibility that the background-onset effect in particular (and perhaps all the results) will not be explained in detail without including more about higher-level visual processing."

Comment: Translation: We'll accept our ad hoc hypo thesis for now, but it's probably wrong. But we'll worry about that later, if and when anyone makes trouble by bothering with actual tests. Because there's always a (zero) chance that it will be corroborated.

Finally, the article also provides a good example of misleading use of references: "Quantal noise exists in the visual stimulus, as is well known (see Pelli for a current discussion.)"

Comment: From Pelli, 1990: "It will be important to test the model…For gratings in dynamic white noise, this [model] prediction has been confirmed by Pelli (1981), disconfirmed by Kersten (1984) and reconfirmed by Thomas (1985). More work is needed." But we don't need to wait for evidence to firmly believe in "quantal noise."

The authors developed some alternative methods for cryopreserving a single chrysanthemum cultivar ‘Escort’ while developing an ultra-rapid freezing protocol for nine chrysanthemum cultivars. In the controlled rate freezing protocol, the authors do not indicate how many shoot tips are placed into each cryovial nor for how long explants are maintained in LN. The same lack of detailed information exists for the encapsulation-dehydration (ED) protocol. In the vitrification protocol, the authors claim that shoot tips were added to a small drop of PVS2 on a sheet of aluminium that was then placed in cryovials and then plunged into LN. However, what was the function of adding the aluminium foil to cryovials? Only for the vitrification protocol do the authors state that “The vials were cooled from underneath to liquid nitrogen temperature to prevent boiling of the liquid nitrogen in the vials.” But it is not clear if such caution was exercised in the other cryopreservation protocols. The density or ratio of explants to medium is never indicated for any protocol. The commercial source of the cryovials and the reagents and equipment is also not described thus the experiment cannot be reliably reproduced. Throughout the manuscript, the authors use two terms, shoot tips and apical shoots to describe the exact same experimental explant, which could be confusing to amateur readers. Much of the description of the protocols is very repetitive and poorly written, and most of the “noise” in the protocol caused by this overlapping information could have been considerably reduced had the authors used suitable acronyms, e.g., SIM for shoot induction medium rather than defining all constituents every time. Fig. 1 legend contains a mistake: it should indicate –1°C but instead it is written as –0.1°C. In Fig. 2 legend, the claim that “There were no statistically significant differences between the different preculture procedures” might be incorrect, considering the wide span between 31% and ~45%. No statistical analyses were conducted on data in Table 1 and Fig. 3, so there is an inconsistent use of statistics and thus interpretation of the data set. All data is represented as only shoot % regeneration, which is not very informative. Shoot numbers would have also been useful. Even though the authors claimed to assess shoot % regeneration from shoot tips after 4 weeks or from callus after 8 weeks, none of the figures or tables indicate the source of the shoots (i.e., from callus or from shoot tips?). Each figure represents different sample sizes, with no apparent explanation, and there is absolutely no discussion about shoot regeneration from callus, which is an undesirable form of clonal propagation for chrysanthemum and could result in somaclonal variation.

This 1957 paper contains the observations of Leo Kanner and his colleague Leon Eisenberg, based on 120 autistic children seen at John Hopkins since Kanner defined the syndrome of "autism" in 1943.

Notably, the authors in this paper suggested that the emotional 'coldness' often seen in parents of autistic children played some causal role in the development of the disorder - though only in conjunction with an 'inborn disturbance of affective contact', i.e. what would today be called a gene x environment interaction.

This idea, taken further, later became notorious as the 'refrigerator mother' psychodynamic theory of autism, associated with the now-discredited Bruno Bettelheim.

By 1971, Kanner denied advocating any kind of psychogenic hypothesis of autism: Kanner L, 1971. However such ideas are certainly evident in this paper.

Dear Reader,

Please provide your kind consideration to the following excerpt from page 502

"There were thrombi in the Thebesian vessels (including the Thebesian veins, the myocardial sinusoids, arterio-luminal and arteriosinusoidal vessels)"

The authors astutely document the various connections in the heart that were described by 1. Thebesius (Thebesian veins) http://bit.ly/vasaThebesii

and the structures described by Joseph T. Wearn

 1. myocardial sinusoids   and the

vessels of Wearn:

 2. arterio-luminal (arterioluminal) 


3. arteriosinusoidal vessels

http://bit.ly/JTWearn

Referring to the vessels of Wearn as Thebesian vessels is problematic as the former are strictly arterial in nature. The vessels described by Thebesius were venular in nature.

Reportedly, Thebesius only studied the veins. In addition, Thebesius neither defined nor studied the "myocardial sinusoids," "arterio-luminal (arteioluminal)," or "arteriosinusoidal" vessels.

Those were defined utilizing serial histologic sections by Wearn et al. The myocardial sinusoids have not been included as strict components of the "vessels of Wearn" as they have been noted to connect with many structures, and Wearn reported that they have a "meandering course."

Therefore, the arterial-cameral connections that bypass the capillary bed are probably best referred to as vessels of Wearn.

The venular-cameral connections that bypass the capillary bed are probably best referred to as any of the synonyms, 1. Thebesian veins (personally preferred term) 2. vessels of Thebesius 3. vasa Thebesii

At least one article uses the terms "Thebesian vessels" and "Thebesian veins" synonymously, (please ask for reference), and I agree that they are synonyms.

However, using the term "Thebesian vessels" to apply to all of the aformentioned connections is both inaccurate and has probably resulted in much confusion in the literature. Therefore, the use of the term "Thebesian vessels," as used in this article, is probably not accurate.

My opinion is that accurate anatomic terminology is a basic principle underlying good medical science, and I ask others to consider whether the aforementioned definitions are appropriate. If this comment is not helpful, please let me know how it might be improved.

Comments and suggestions are welcome.

Thank you very much.

Rotifers: Rotifers are an important part of the freshwater zooplankton, being a major foodsource and with many species also contributing to the decomposition of soil organic matter. Most rotifers are around 0.1–0.5 mm long, and are common in freshwater environments throughout the world. The word "rotifer" is derived from a Latin word meaning "wheel-bearer", due to the corona around the mouth that in concerted sequential motion resembles a wheel (though the organ does not actually rotate). The coronal cilia create a current that sweeps food into the mouth. Rotifers eat particulate organic detritus, dead bacteria, algae, and protozoans. They eat particles up to 10 micrometres in size. Like crustaceans, rotifers contribute to nutrient recycling. For this reason, they are used in fish tanks to help clean the water, to prevent clouds of waste matter.(Wikipedia was used).

Abstract of this paper, with some comment. ** The content of the article in short: A new solution to eutrophication. New concept of eutrophication control. Rating of this paper: In the top 25% of all articles scored by Altmetric. ** A new way of eutrophication control was suggested in the paper. The author suggested a new component of the measures against eutrophication: reducing the input of the chemical pollutants that weaken the potential of the filter-feeders for removing planktonic algae. The suggested way of controlling eutrophication is applicable to both freshwater and marine ecosystems. The article proposed a new idea, a new way of controlling eutrophication. The article is based on a series of the author's experiments with aquatic organisms (filter-feeders) that discovered and quantified relevant toxic effects of organic pollutants at sublethal concetrations. This article presented some new data to continue this line of research that is essential to the new solution to eutrophication. Among new facts that were reported in the paper, in addition to a substantial amount of relevant, related data previously obtained by the author: The liquid detergent (exemplified by the dish washing liquid, Fairy) 2 mg/L inhibited filtration by the bivalve mollusks, marine mussels (Mytilus galloprovincialis) within 2-23 min after addition, at temperature 22.5 ºС. This species of bivalve mollusks is one of key species in marine benthic ecosystems; it is one of ecological engineers that make a great impact on water quality. This is only one new fact that adds to many other facts (on how chemical pollutants can inhibit water filtration) discovered and reported by the author in other publications (papers and the book, Biological Effects of Surfactants). The paper presents a new approach to combat eutrophication.

Abstract: The author identified a new type of ecological hazard of anthropogenic impact (using chemical pollution as an example), which he proposed to term “synecological summation” or “synergistic summation” of anthropogenic effects on organisms of two adjacent trophic levels. ** NEW FACTS: in the study reported in the paper, the following new type of environmental hazards was found. It was shown that even some relatively mild influences on organisms of two adjacent trophic levels may eventually produce a synergistic, pronounced and definitely undesirable effect which will lead to an abnormal increase in the abundance of organisms of one of the trophic levels. The concrete examples of that type of synergism were found when anthropogenic impacts affected the organisms of two adjacent trophic levels (bivalves and algae). Some new bioeffects of the action of the synthetic detergent (exemplified by the laundry detergent, namely, the detergent 'Vesna') (1 mg/l) on the bivalves, oysters Crassostrea gigas were described. Also, some new effects of the detergent (exemplified by the laundry detergent, namely, the detegent 'IXI') (10 mg/l) on the marine mussels Mytilus galloprovincialis, were found; also, new effects of the detergent (exemplified by the laundry detergent, namely the detergent 'Tide-Lemon') (50 mg/l) on M. galloprovincialis were discovered. ** CONCLUSION: The hazard of simultaneous influence of contamination of environment (e.g., by detergents) on organisms of the two trophic levels may occur when the polluting chemicals produce effects on algae and bivalves that are filter-feeders. It means that a new type of environmental hazards was discovered.

Abstract: Responses of the freshwater bivalve Unio tumidus to mixed chemical preparations and the hazard of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, p. 492-495. ISSN 0012-4966 (Print) 1608-3105 (Online). DOI 10.1023/A:1012344026176. The author introduced a new concept and term, “the synecological summation of the effects of anthropogenic factors on organisms”. In the new author’s experiments, the effects of commercial detergents, which are chemical mixtures, on bivalves (e.g. effects of the laundry detergent OMO on the freshwater mussels Unio tumidus) were discovered and studied. Detergents exert two types of hazardous effects on organisms and ecosystems: the phosphorus-induced stimulation of phytoplankton growth and surfactant-induced inhibition of filter-feeders. Because filter-feeders are an effective natural factor of control of unicellular plankton populations, the two types of the detergent-induced effects on ecosystem facilitate the growth of phytoplankton populations. Therefore, these effects sum together, thereby increasing the hazard of the man-made impact on the ecosystem. The results contribute to a better understanding of the potential ecological danger of pollutants for integral functions of ecosystems. It is the synecological summation of the effects of anthropogenic factors on plankton populations and filter-feeders that is of particular concern. The interaction between populations of plankton organisms and filter-feeders that feed on plankton should be taken into consideration in the studies on the ecological effects of synthetic detergents on these populations. Situations of man-made impact should be analyzed with using the synecological approach to the problem. http://sites.google.com/site/2001dbs380p492unio/; www.springerlink.com/index/L33309208H28L87R.pdf; DOI 10.1023/A:1012344026176;

Why the plant species, Nuphar lutea (Yellow Water-lily) , was used in this research project: it is one of the most common aquatic plant species in the freshwater habitats of Eurasia. Why the plant species, Taraxacum officinale, was used in this research project: it is a common laboratory practice to feed the great pond snail with leaves of this higher plant. Why the synthetic surfactants ТDТМА (tetradecyltrimethylammonium bromide) and SDS (sodium dodecyl sulfate) were used: they are representatives of the two major classes of synthetic surfactants, namely, cationic surfactants, and anionic surfactants. These two chemicals were studied in many other publications of Dr. Sergei Ostroumov, so that lots of data to compare toxic effects of these chemicals on organisms are available. A detailed explanation of methodology was also published in the book Biological Effects of Surfactants (Ostroumov, 2005, https://www.researchgate.net/publication/200637626)

Comment on the biological species that were studied in this paper: the great pond snail is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. Range Description: A widespread species distributed in Asia (central, north and south and southeast), north America, north Africa and New Zealand. The great pond snail has a shiny yellowish brown shell.

Nuphar lutea (Yellow Water-lily) is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia.

Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Unio is the type genus of the family Unionidae. About this family: The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks.

On 2015 Dec 13, S A Ostroumov commented:

Explanation of terminology: pellets are the particles of the undigested organic matter (mainly biomass of undigested food) that the aquatic mollusks (snails and freshwater mussels) excrete so that these mollusks function as engines that drive the transfer of a significant amount of the organic matter through aqautic ecosystems.

DOI: 10.1023/a:1011600213221. This paper proved that even chemical pollutants that are not toxic to phytoplankton can influence abundance of the phytoplankton. It is intereting that some chemical pollutants (which are not nutrients) can finally stimulate the abundance of phytoplankton. How? See the article.

On 2015 Jan 19, Paul Korir commented:

This paper claims that in about half (49%) of transcription units with multiple splice forms it appeared that usage of an alternative TSS was accompanied by alternative splicing of the initial exon. The authors therefore conclude that this might imply that alternative TSS may induce alternative splicing. However, if a transcription unit has a 50-50 chance of exhibiting this behaviour that would be the last conclusion that one could make. There are no positive epistemic implications that can be derived from a 50-50 chance; in fact, this is state with the maximal entropy and by extension the most uncertainty.

On 2015 Oct 28, Peter Gøtzsche commented:

The authors write that "approximately 50-60% of patients are thought to improve clinically as a consequence of antidepressant treatment." This is not correct. About 50% of the patients get better on an antidepressant and 40% on placebo, ie. only a 10% difference, and according to the patients’ own judgments, the drugs don’t work (1,2). Furthermore, these trials were not effectively blinded, and if atropine is put in the placebo to blind the trials better, even the psychiatrists cannot find any effect (3).

The authors write that, "Currently there is no evidence to suggest that ECT causes any kind of brain damage, although temporary cognitive impairment is frequently reported" and that "ECT seems to be a safe procedure". This is not the case. ECT is highly controversial (4), patients report permanent memory problems (5), and there seems to be a death rate of about 1 per 1000 (6).

Only one RCT met the inclusion criteria and that trial was a post-hoc analysis of data in elderly people who participated in the Nottingham trial. It would be of interest to readers to know what the Nottingham trial showed.

On 2013 Jun 15, Wolfgang Huber commented:

We performed a re-analysis of the same data using a variety of other, more standard classification procedures and could not reproduce the reported prediction accuracy. It is possible that the reported prediction accuracy was measured in a way that is sensitive to over-fitting, due to the high-dimensionality of the data and the choices that can be made for data "pre-processing". Our analysis was summarised in Ruschhaupt M, 2004 (pdf: http://www-huber.embl.de/pub/pdf/sagmb_2004.pdf).

On 2015 Nov 30, S A Ostroumov commented:

The results of this study are really interesting and innovative. I had some experience of studying phytoremediation with this plant species, Myriophyllum aquaticum (parrot feather). It has a high potential for decontamination of aquatic environment. This paper provided new facts in support of good prospects of using this plant species. The test system with rotifers (Brachionus calyciflorus) feeding on an algal species (Nannochloropsis spp.) is also an interesting feachure of this paper. This test system was successfully used also in this paper: www.researchgate.net/publication/200578650;

DAVID is continuously being used as evidenced by its numerous citations in current biomedical literature http://bit.ly/1FS1JgT. However, the data resources used by DAVID appear to not have been updated since 2009 http://david.abcc.ncifcrf.gov/helps/update.html. The fact that DAVID has not been updated going on 5 years calls into question the current utility of using this tool.

Half-life of Factor VIII in patients with haemophilia A: comparison between B-domain deleted recombinant Factor VIII and full-length recombinant Factor VIII.

The study by Gruppo et al. [1] has described an analysis in which the half-life of Factor VIII was compared among plasma-derived concentrates , B-domain deleted recombinant products (BDD-rFVIII), and full-length recombinant products (FL-rFVIII). While the issue of the differences between plasma-derived concentrates and recombinant products has been debated in very numerous papers, the difference in the half-life between BDD-rFVIII and FL-rFVIII is a quite original finding, particularly because the authors conducted a pooled analysis based on a specific meta-analytical model (random-effect model). In their meta-analysis, however, Gruppo et al. [1] did not present any Forest plot; furthermore, some details were missing concerning the methods (e.g. the statistical software used for the analysis) and the results (e.g. the evaluation of heterogeneity). For this reason, we have re-analyzed the half-life data reported by Gruppo et al. [1] in their Table 3 and Figure 2 for BDD-rFVIII and FL-rFVIII. Our analysis was based on the Open Meta-analyst software (Open Meta-Analyst, version 4.16.12, Tufts University, url http://tuftscaes.org/open_meta/) and included the assessment of heterogeneity. The results of our re-analysis (study-specific and meta-analytic values of half-life with Forest plot and estimates of confidence intervals and heterogeneity) are available at the following Internet link: http://www.osservatorioinnovazione.net/papers/gruppo2003-reanalysis.pdf Our estimates of half-life for BDD-rFVIII and FL-rFVIII are nearly identical to those found by Gruppo et al.[1]. As expected, our results have also confirmed that the half-life of BDD-rFVIII is significantly shorter than that of FL-rFVIII
