Parastoo Afshari, Nabiollah Abolfathi
Blood wicking in its steady state form -i.e. the uniform distribution of blood cells in plasma- is completely different from its coagulated form on a porous surface like paper. The hydrophilic property of the Cellulose leads to a Significant wicking of the blood cells on paper fibers after being rinsed by the isotonic solution. The difference in the wicking length of the blood cells in a steady state and the coagulated form could be considered as a criterion to recognize the blood type in paper-based kit. However, due to the molecular structure of the nitrocellulose, a better process occurs while separating the coagulated blood from the steady form of cells...

The transcription error rate estimated from mistakes in end product RNAs is 10(-3)-10(-5) We analyzed the fidelity of nascent RNAs from all actively transcribing elongation complexes (ECs) in Escherichia coli and Saccharomyces cerevisiae and found that 1-3% of all ECs in wild-type cells, and 5-7% of all ECs in cells lacking proofreading factors are, in fact, misincorporated complexes. With the exception of a number of sequence-dependent hotspots, most misincorporations are distributed relatively randomly. Misincorporation at hotspots does not appear to be stimulated by pausing...

Any animal, human or non-human, lives in a world where there are others like itself. Individuals' behaviors are thus inevitably influenced by others, and cognition is no exception. Long acknowledged in psychology, social modulations of cognition have been neglected in cognitive neuroscience. Yet, infusing this classic topic in psychology with brain science methodologies could yield valuable educational insights. In recent studies, we used a non-human primate model, the rhesus macaque, to identify social influences representing ancient biases rooted in evolution, and neuroimaging to shed light on underlying mechanisms...

The present generation of women of childbearing age more frequently suffer from overweight, obesity, initial as well as fully established metabolic syndrome, which together with postponing motherhood until the third decade in life plays an important role in the increasing incidence of gestational diabetes (GDM) that currently affects about 1/5 of pregnant women. However the causal link between diabetes during pregnancy and metabolic diseases in the whole population is mutual. By way of epigenetic changes, maternal diabetes unfavourably programmes metabolism of the offspring, who tend to transfer the disorder to the next generations...

Perceptions of failure have been implicated in a range of psychological disorders, and even a single experience of failure can heighten anxiety and depression. However, not all individuals experience significant emotional distress following failure, indicating the presence of resilience. The current systematic review synthesised studies investigating resilience factors to emotional distress resulting from the experience of failure. For the definition of resilience we used the Bi-Dimensional Framework for resilience research (BDF) which suggests that resilience factors are those which buffer the impact of risk factors, and outlines criteria a variable should meet in order to be considered as conferring resilience...

BACKGROUND: Iatrogenic medication errors due to calculation errors are an under-reported concern in children. OBJECTIVE: To determine the incidence and source of iatrogenic medication errors in a paediatric intensive care unit (PICU). METHODS: A prospective study was conducted in the PICU at Inkosi Albert Luthuli Hospital, Durban, South Africa, over a 3-month period in 2014. Medication-related calculation skills of medical practitioners and nurses were assessed through the voluntary anonymous completion of a questionnaire...

Z Harcombe, T D Noakes
A 2014 meta-analysis from the universities of Stellenbosch and Cape Town reported that diets with a lower-carbohydrate (CHO) content are no more effective for producing weight loss than are high-CHO diets, so-called isoenergetic 'balanced' diets. We have re-examined the article and found numerous errors, many material in nature. Studies were included that failed the authors' own inclusion criteria; invalid and subjective meta-analysis sub-grouping was used; and data extraction was repeatedly inaccurate. All but one error favoured the balanced diet...

In maladaptive respects, perfectionism reflects an individual's concern over making mistakes and doubting the quality of his or her own actions excessively, which would affect one's emotion. However, little is known about the neural mechanisms associated with the perfectionism and negative affect. In this study, voxel-based morphometry was performed to identify the brain regions underlying individual differences in perfectionism, which was measured by the Chinese Frost Multidimensional Perfectionism Scale (CFMPS), in a large sample of nonclinical young adults...

Individual dose estimates calculated by Dosimetry System 2002 (DS02) for the Life Span Study (LSS) of atomic bomb survivors are based on input data that specify location and shielding at the time of the bombing (ATB). A multi-year effort to improve information on survivors' locations ATB has recently been completed, along with comprehensive improvements in their terrain shielding input data and several improvements to computational algorithms used in combination with DS02 at RERF. Improvements began with a thorough review and prioritization of original questionnaire data on location and shielding that were taken from survivors or their proxies in the period 1949-1963...

Environmental and bio-ecological changes, some administrative and political mistakes, and global warming seriously affect the behaviors of ticks in Turkey and globally. The global public sensitivity toward tick infestations has increased along with increases in tick-borne diseases (TBDs). Recently, the World Health Organization (WHO) developed a new political concept, "One Health," for specific struggle strategies against tick infestations and TBDs. To highlight the importance of the issue, the WHO had declared the year 2015 for vector-borne diseases and adopted the slogan "small bites big threat"...

Statistical editors of the Malaysian Journal of Medical Sciences (MJMS) must go through many submitted manuscripts, focusing on the statistical aspect of the manuscripts. However, the editors notice myriad styles of reporting the statistical results, which are not standardised among the authors. This could be due to the lack of clear written instructions on reporting statistics in the guidelines for authors. The aim of this editorial is to briefly outline reporting methods for several important and common statistical results...

This study investigated perceptions of and engagement with the concepts of planning and problem-solving, within a weight management sample. A total of 53 participants (62% female, 20-74 years old) completed a semi-structured interview and quantitative measures after a 16-week weight maintenance period. Preliminary weight maintainers (who had maintained losses of, at least 10% of their original weight) were compared with heavier-than-baseline participants (who had re-gained more weight than was originally lost)...

Based on our original knowledge and experience on both polychlorinated biphenyls (PCBs) identification in aquatic ecosystems, and use of ionic liquids (ILs) as solvents and/or co-catalysts in green chemistry, we drawn a dared comparison between these two families. Indeed, PCBs has been used during several decades for their new properties, but are now considered as prevalent and persistent pollutants; some toxic effects on environment or human are still revealed. ILs, often designated as "green solvents" are increasingly used in numerous applications, but few studies reported about their environmental impact are still controversial...

Motivational beliefs and values influence how children approach challenging activities. The current study explored motivational processes from an expectancy-value theory framework by studying children's mistakes and their responses to them by focusing on two event-related potential (ERP) components: the error-related negativity (ERN) and the error positivity (Pe). Motivation was assessed using a child-friendly challenge puzzle task and a brief interview measure prior to ERP testing. Data from 50 4- to 6-year-old children revealed that greater perceived competence beliefs were related to a larger Pe, whereas stronger intrinsic task value beliefs were associated with a smaller Pe...

The medical profession is considered to be one of the noblest professions in the world. The practice of medicine is capable of rendering noble service to humanity provided due care, sincerity, efficiency, and professional skill is observed by the doctors. However, today, the patient-doctor relationship has almost diminished its fiduciary character and has become more formal and structured. Doctors are no longer regarded as infallible and beyond questioning. Corporatization of health care has made it like any other business, and the medical profession is increasingly being guided by the profit motive rather than that of service...

Increasing use of engineered nanoparticles has led to extensive research into their potential hazards to the environment and human health. Cellular uptake from the gut is sparsely investigated and microscopy techniques applied for uptake studies can result in misinterpretations. Various microscopy techniques are used to investigate internalization of 10 nm gold nanoparticles in Daphnia magna gut lumen and gut epithelial cells upon 24h exposure and outline potential artefacts, i.e. high contract precipitates from sample preparation related to these techniques...

PURPOSE: Belief in conspiracy theories about societal events is widespread among citizens. The extent to which conspiracy beliefs about managers and supervisors matter in the micro-level setting of organizations has not yet been examined, however. We investigated if leadership styles predict conspiracy beliefs among employees in the context of organizations. Furthermore, we examined if such organizational conspiracy beliefs have implications for organizational commitment and turnover intentions...

Recently there has been a growing concern that many published research findings do not hold up in attempts to replicate them. We argue that this problem may originate from a culture of 'you can publish if you found a significant effect'. This culture creates a systematic bias against the null hypothesis which renders meta-analyses questionable and may even lead to a situation where hypotheses become difficult to falsify. In order to pinpoint the sources of error and possible solutions, we review current scientific practices with regard to their effect on the probability of drawing a false-positive conclusion...
