INTRODUCTION: Recent studies have shown that stimulation occurs at the anode of stimulating electrodes instead of anodal block. This phenomenon may become a pitfall in F-wave examinations. METHODS: Subjects were 10 healthy volunteers. Their ulnar nerve was stimulated at the wrist with the cathode placed distally. Antidromic impulses were evaluated using the mixed nerve action potential (MNAP) at the elbow. RESULTS: Anodal stimulation occurred for both sensory and motor fibers at 22 mm proximal to the anode on average, which may theoretically shorten the F-wave latency by about 0...

The hippocampus plays a key role in pattern separation, the process of transforming similar incoming information to highly dissimilar, non-overlapping representations. Sparse firing granule cells (GCs) in the dentate gyrus (DG) have been proposed to undertake this computation, but little is known about which of their properties influence pattern separation. Dendritic atrophy has been reported in diseases associated with pattern separation deficits, suggesting a possible role for dendrites in this phenomenon...

BACKGROUND: People often change their opinions or behavior to match the responses of others, a phenomenon known as social conformity. Conforming behavior varies substantially across individuals. However, little is known about the genetic basis underlying individual differences in social conformity. A recent study demonstrated an association between enhanced dopaminergic function and increased conforming behavior. Given the effect of the dopamine receptor 3 gene (DRD3) Ser9Gly polymorphism (rs6280) on dopamine release in the striatum, this study investigated to what extent this polymorphism affects conforming behavior...

Objective: to analyze the intimate partner violence in adolescence from the perspective of gender and generation. Method: Quantitative, descriptive, and exploratory research. 111 adolescents participated in this study, with ages from 15 to 19 years old. Results: We found that 91% of participants have perpetrated and 90.1% have undergone at least one of the natures of violence. The intimate partner violence in adolescence constitutes a form of gender violence, and gender constructions have determined the suffered and perpetrated aggressions, possibly also determining the naturalization and legitimization of such aggressions...

Vaccinations and the controversy around them always go in parallel. We identified four categories blending in various amounts of truth and imagination: history, myths, shams and frauds. Over the years, they have alternated and sometimes transformed into one another. This sharp separation into categories is certainly academic and forced. In fact, the line between these aspects is not clear enough to allow a rigid and well-defined division. Our work starts from the category containing the most truthfulness: history, and goes on to analyze two categories that add fantasy to facts: myths and shams (or better, "old wives' tales")...

A second victim has been defined as "a healthcare worker involved in an unanticipated adverse patient event, medical error and/or a patient related-injury who becomes victimized in the sense that the worker is traumatized by the event". The aim of the present research study was to assess the "second victim" phenomenon in Italy. Fifty interviews were conducted with different health care professionals previously involved in medical errors. All study participants clearly remembered the event. Support obtained by second victims was poor and inefficient...

Mammalian genomes are pervasively transcribed to produce thousands of long non-coding RNAs (lncRNAs). A few of these lncRNAs have been shown to recruit regulatory complexes through RNA-protein interactions to influence the expression of nearby genes, and it has been suggested that many other lncRNAs can also act as local regulators. Such local functions could explain the observation that lncRNA expression is often correlated with the expression of nearby genes. However, these correlations have been challenging to dissect and could alternatively result from processes that are not mediated by the lncRNA transcripts themselves...

BACKGROUND: Point-of-care ultrasonography (POCUS) is a widely used tool in emergency and critical care settings, useful in the decision-making process as well as in interventional guidance. While having an impressive diagnostic accuracy in the hands of highly skilled operators, inexperienced practitioners must be aware of some common misinterpretations that may lead to wrong decisions at the bedside. OBJECTIVES: This article provides a revision list of common POCUS misdiagnoses usually found in practice and offers useful tips to recognize and avoid them...

The so-called syllable position effect in speech errors has been interpreted as reflecting constraints posed by the frame structure of a given language, which is separately operating from linguistic content during speech production. The effect refers to the phenomenon that when a speech error occurs, replaced and replacing sounds tend to be in the same position within a syllable or word. Most of the evidence for the effect comes from analyses of naturally occurring speech errors in Indo-European languages, and there are few studies examining the effect in experimentally elicited speech errors and in other languages...

In the last decades, Egypt has been suffering from the phenomenon of black cloud resulting from burning rice husk and increasing the demand for water leading to the water crisis. An alternative, low-value and surplus agricultural byproduct (rice husk, RH) has an enormous potential for the removal of Cu(II) ions from water. The present study focuses on the chance of the use of rice husk as a bio-adsorbent without any chemical treatment instead of burning it and soiling the environment. The elemental, structural, morphological, surface functional, thermal, and textural characteristics of RH are determined by XRF, XRD, SEM, FT-IR, TGA, and BET surface area, respectively, and contributed to the understanding of the adsorption mechanism of Cu(II) ions in aqueous solution...

PURPOSE: Microsatellite instability (MSI) has been a long-standing biomarker candidate for drug resistance in tumour cells. Despite numerous clinical studies, the data in the literature are not conclusive. The complexity of the MSI phenomenon in some malignancies may, at least partly, account for the discrepancy. In addition, methodological problems are also pointed out in the assay techniques. We previously established a unique fluorescent technique in which the major methodological problems in conventional assays are overcome...

BACKGROUND: Conjoined twins are a rare medical phenomenon that offers a unique challenge for medical professionals. The complex anatomy of conjoined twins dictates their survival and amenability to separation, making each case different in terms of medical management, surgical planning, and patient outcomes. Thoraco-omphalo-ischiopagus twins, joined from the thorax to the pelvis, are one of the rarest orientations recorded in the medical literature, and successful separation of this subset of conjoined twins has not been documented...

It is well understood that in some cases proteins do not fold correctly and, depending on their environment, even properly-folded proteins change their conformation spontaneously, taking on a misfolded state that leads to protein aggregation and formation of large aggregates. An important factor that contributes to the aggregation is the interactions between the misfolded proteins. Depending on the aggregation environment, the aggregates may take on various shapes forming larger structures, such as protein plaques that are often toxic...

In most Eu(3+) activated phosphors, only red luminescence from the (5)D0 is obtainable, and efficiency is limited by concentration quenching. Herein we report a new phosphor of Ca4LaO(BO3)3:Eu(3+) (CLBO:Eu) with advanced photoluminescence properties. The yellow luminescence emitted from the (5)D1,2 states is not thermally quenched at room temperature. The relative intensities of the yellow and red emission bands depend strongly on the Eu(3+) doping concentration. More importantly, concentration quenching of Eu(3+) photoluminescence is absent in this phosphor, and the stoichiometric compound of Ca4EuO(BO3)3 emits stronger luminescence than the Eu(3+) doped compounds of CLBO:Eu; it is three times stronger than that of a commercial red phosphor of Y2O3:Eu(3+)...

Sexual dimorphism is an interesting biological phenomenon. Previous studies showed that DNA methylation might play a role in sexual dimorphism. However, the overall picture of the genome-wide methylation landscape in sexually dimorphic species remains unclear. We analyzed the DNA methylation landscape and transcriptome in hybrid tilapia (Oreochromis spp.) using whole genome bisulfite sequencing (WGBS) and RNA-sequencing (RNA-seq). We found 4,757 sexually dimorphic differentially methylated regions (DMRs), with significant clusters of DMRs located on chromosomal regions associated with sex determination...
