This scientific article demonstrates a dynamic and rigorous evolution.

15-Point versus pass/fail grading in orthodontic education: A randomized controlled trial.

Objectives: There is a lack of evidence on whether a grading system or a pass/fail system influences manual skills in dental education. This parallel-group randomized controlled trial aimed to assess the influence of a 15-point grading system compared with a pass/fail evaluation on the quality of orthodontic appliances in dental education.

Methods: Predoctoral dental students of three orthodontic courses (n = 139) were randomly assigned to either the test group (15-point grading system) or the control group (pass/fail) using sealed envelopes.

Effect of physical activity on social communication impairments in children with autism spectrum disorder: A meta-analysis.

This study aims to develop a foundational evaluation model for manual therapy learning among rehabilitation students, based on the Delphi method, and to analyze the theoretical basis and practical significance of this model.

Methods: An initial framework for evaluating the fundamentals of manual therapy learning was constructed through a literature review and theoretical analysis.

Leveraging spiking neural networks for topic modeling.

This article investigates the application of spiking neural networks (SNNs) to the problem of topic modeling (TM): the identification of significant groups of words that represent human-understandable topics in large sets of documents. Our research is based on the hypothesis that an SNN that implements the Hebbian learning paradigm is capable of becoming specialized in the detection of statistically significant word patterns in the presence of adequately tailored sequential input. To support this hypothesis, we propose a novel spiking topic model (STM) that transforms text into a sequence of spikes and uses that sequence to train single-layer SNNs.

Protopine and Allocryptopine Interactions with Plasma Proteins.

A research synthesis on successful educational practices and student outcomes for physical education in schools.

Although successful educational practices (SEPs) in higher education institutions have well-established student outcomes, the vast majority do not meet physical education standards in schools. Despite the promising nature of policy initiatives supporting schools, there is scant evidence of how these SEPs affect student outcomes. This review aimed to determine the status of the literature and the type of evidence regarding school SEPs.

Mental illness and cardiovascular health: observational and polygenic score analyses in a population-based cohort study.

Background: Individuals with serious mental illness have a markedly shorter life expectancy. A major contributor to premature death is cardiovascular disease (CVD). We investigated associations of (genetic liability for) depressive disorder, bipolar disorder and schizophrenia with a range of CVD traits and examined to what degree these were driven by important confounders.

Spike-Timing-Dependent Plasticity With Activation-Dependent Scaling for Receptive Fields Development.

Spike-timing-dependent plasticity (STDP) is one of the most popular and deeply biologically motivated forms of unsupervised Hebbian-type learning. In this article, we propose a variant of STDP extended by an additional activation-dependent scale factor. The consequent learning rule is an efficient algorithm, which is simple to implement and applicable to spiking neural networks (SNNs).

Image analysis discloses differences in nuclear parameters between ERG+ and ERG- prostatic carcinomas.

Prostatic carcinoma (PC) is the most frequent urologic cancer and one of the most frequent cancers in males; it is a heterogeneous disease, in terms of molecular features, morphology and prognosis. About half of cases depends on TMPRSS2-ETS translocation which leads to a production of ERG transcription factor. ERG+ and ERG- cancers seem to differ in a number of features, which could lead to an altered nuclear structure; the aim of the study was to test this hypothesis.

The Influence of Trehalose on Atherosclerosis and Hepatic Steatosis in Apolipoprotein E Knockout Mice.

Atherosclerosis and nonalcoholic fatty liver disease (NAFLD) are frequent causes of death in the Western countries. Recently, it has been shown that autophagy dysfunction plays an important role in the pathogenesis of both atherosclerosis and NAFLD; thus, activators of autophagy might be useful for novel therapeutic interventions. Trehalose-a naturally occuring disaccharide present in plants, bacteria, fungi, insects, and certain types of shrimps-is a known inducer of autophagy.

The Autonomic Innervation and Uterine Telocyte Interplay in Leiomyoma Formation.

The autonomic innervation of the uterus is involved in multiple pathophysiological processes in both humans and animals. Pathological conditions such as adenomyosis or inflammatory pelvic disease are usually accompanied by significant alterations in uterine innervation. In the current study, we focused on autonomic innervation of uterine fibroids, the identification of recently described interstitial cells, telocytes, and the possible interplay between these structures.

Quantitative proteomics reveals decreased expression of major urinary proteins in the liver of apoE/eNOS-DKO mice.

Endothelial nitric oxide synthase (eNOS)-derived nitric oxide (NO) plays an important role, not only in endothelium-dependent vasodilation but also in lipid and glucose homeostasis in the liver and exerts beneficial effects on mitochondrial biogenesis and respiration. Thus, the aim of our study was to use iTRAQ-based quantitative proteomics to investigate the changes in protein expression in the mitochondrial and cytosolic fractions isolated from the liver of the double (apolipoprotein E (apoE) and eNOS) knockout (apoE/eNOS-DKO) mice as compared to apoE KO mice (apoE ) - an animal model of atherosclerosis and hepatic steatosis. Collectively, the deficiency of eNOS resulted in increased expression of proteins related to gluconeogenesis, fatty acids and cholesterol biosynthesis as well as the decreased expression of proteins participated in triglyceride breakdown, cholesterol transport, protein transcription & translation and processing in endoplasmic reticulum (ER).
