Due to the magnitude of chemical space, the discovery of novel substrates in energy transfer (EnT) catalysis remains a daunting task. Experimental and computational strategies to identify compounds that successfully undergo EnT-mediated reactions are limited by their time and cost efficiency. To accelerate the discovery process in EnT catalysis, we herein present the EnTdecker platform, which facilitates the large-scale virtual screening of potential substrates using machine-learning (ML) based predictions of their excited state properties...

Introduction Physician attire has been shown to influence patients' impression of their healthcare provider. Scrubs and formal office attire are interchangeably worn by physicians. This study aimed to determine differences in scrubs and formal office attire on patient perceptions of professionalism, friendliness, aptitude, and empathy. Methods A single-center questionnaire study was conducted and a total of 150 patients were included. Patients were recruited from the inpatient and outpatient settings. Patients completed a questionnaire in which they rated 22 photographs...

OBJECTIVE: To validate the Vocal Tract Discomfort Scale for the Brazilian Portuguese (VTDS-BR), based on internal consistency, reliability, and accuracy. METHODS: The participants were 431 adults of both sexes, divided in two groups: dysphonia (DG) and vocally healthy (VHG). We built a digital database with personal, professional information and the item-by-item VTDS-BR responses of the participants. We applied Cronbach's alpha, exploratory factor analysis; confirmatory factor analysis; Item Response Theory (IRT) using the Samejima model; and ROC (Receiver Operating Characteristic) curve analysis to obtain the VTDS-BR cut-off point...

Exercise has the unique aptitude to benefit overall health of body and brain. Evidence indicates that the effects of exercise can be saved in the epigenome for considerable time to elevate the threshold for various diseases. The action of exercise on epigenetic regulation seems central to building an "epigenetic memory" to influence long-term brain function and behavior. As an intrinsic bioenergetic process, exercise engages the function of the mitochondria and redox pathways to impinge upon molecular mechanisms that regulate synaptic plasticity and learning and memory...

Aptitude test scores are typically interpreted similarly for examinees with the same overall score. However, research has found evidence of examinee differences in strategies, as well as in the continued application of appropriate procedures during testing. Such differences can impact the correlates of test scores, making similar interpretations for equivalent scores questionable. This study presents some item response theory (IRT) models that are relevant to identifying examinee differences in strategies and understanding of test-taking procedures...

With the increased emphasis on competition in academic settings, anxiety is becoming more common, which inevitably has some impact on students' learning processes and results. This study aimed to explore how competition-induced anxiety influences students' subjective cognitive load (SCL), attention levels, and test scores. We also investigated the mediating role of the behavioral inhibition system/behavioral activation system (BIS/BAS) in those factors. A total of 101 college students were recruited in Study 1 to learn from five micro-lectures from massive open online courses (MOOCs) under competitive and non-competitive conditions...

BACKGROUND: During their training, pre-professional ballet students are confronted with physical stresses comparable to those of competitive sports. In competitive sports, there are mandatory and binding aptitude tests to ensure that the growing athlete meets the requirements. In ballet, there are no such mandatory examinations preceding the start of training. For adult professional dancers, musculoskeletal ideals could be isolated from the dance medicine literature. However, only a few studies describe musculoskeletal characteristics of pre-professional ballet students...

PURPOSE: This article aims to describe the causes of ophthalmological disqualification from the military services detected during specialist consultations conducted at Army Training Hospitals. METHODS: This observational, cross-sectional, multicenter study retrospectively included individuals deemed as "unfit for military service" due to eye diseases identified during the specialist consultation conducted at 3 ATHs between January 2020 and December 2021. The data collected included age, medical and surgical history, reasons for ophthalmological disqualification, uncorrected distance visual acuity, best corrected distance visual acuity and cycloplegic refraction...

The availability of reliable information on local climatic-tourism conditions is a growing need due to the influence it exerts on the quality of the organizational strategy of tourist destination's, and travel experience. Evaluations of the tourism potential of the climate have been carried out on a daily or monthly resolution, thus limiting the collection of detailed information that makes it possible to fine-tune tourism management and operational decision-making on an intraday scale. This research is the first case study to analyse the climatic suitability for nature tourism, using the weather types method at hourly resolution...

Fractions were isolated from the leaves extract of Kalanchoe pinnata and subjected to scrutiny for their prospective anti-obesity properties. An array of preliminar y phytochemical, invitro antioxidant, and enzyme inhibition assays were executed, which discerned fractions F1 and F2 as the most effective fractions. These fractions were subsequently studied through invivo experiments, affirming that F2 as the most potent fraction. Further characterisation of F2 was conducted via HPTLC-Mass spectrometry (MS-MSn ) techniques...

Considered until recently unfit to rear children, non-heterosexual people have been excluded from forming families in most countries. Many, worldwide, demand access to family formation, claiming the same aptitudes as heterosexual people for raising children. However, when non-heterosexual singles and couples want to become parents in Spain, they must consider transnational contexts, resorting to inter-country adoption or surrogacy abroad, processes that contribute to delay their family formation. They must consider not only Spanish sociocultural conditions, but other countries' legal restrictions regarding parents' gender, social status, and sexual identity...

INTRODUCTION: Canine olfaction is a potential means for detection of respiratory disease in beef cattle. In a prior study, two dogs were trained to discriminate between nasal swabs from healthy cattle and cattle that developed Bovine Respiratory Disease. Dogs had some ability to identify samples from BRD-affected cattle, but results were ambiguous. The purpose of this study was to evaluate more dogs using better-controlled training and testing procedures. METHODS: Nasal and saliva swabs were collected from 96 cattle before and after administering a vaccine to induce an inflammatory immune response...

INTRODUCTION: Musical roundness perception relies on consonance/dissonance within a rule-based harmonic context, but also on individual characteristics of the listener. The present work tackles these aspects in a combined psychoacoustic and neurophysiological study, taking into account participant's musical aptitude. METHODS: Our paradigm employed cadence-like four-chord progressions, based on Western music theory. Chord progressions comprised naturalistic and artificial sounds; moreover, their single chords varied regarding consonance/dissonance and harmonic function...

DESIGN: We used a convergent mixed-methods study design, and the International Classification of Functioning, Disability and Health to operationalize the core constructs and influencing factors related to physical and psychosocial functioning, and food and nutrition. SETTING: Three Veterans Affairs Polytrauma Rehabilitation Centers...

BACKGROUND: Most recombinant Komagataella phaffii (Pichia pastoris) strains for protein production are generated by genomic integration of expression cassettes. The clonal variability in gene copy numbers, integration loci and consequently product titers limit the aptitude for high throughput applications in drug discovery, enzyme engineering or most comparative analyses of genetic elements such as promoters or secretion signals. Circular episomal plasmids with an autonomously replicating sequence (ARS), an alternative which would alleviate some of these limitations, are inherently unstable in K...

This study isolated and identified autochthonous lactic acid bacteria (LAB) from mandacaru fruit and evaluated their potential probiotic and technological aptitudes in vitro, as well as the protective effects of freeze-dried mandacaru fruit on the most promising LAB isolate during lyophilization and refrigeration storage. Initially, 212 colonies were isolated from mandacaru fruit, and 34 were preliminarily identified as LAB. Thirteen isolates identified by 16S-rRNA sequencing as Pediococcus pentosaceus were negative for DNase, gelatinase, hemolytic, and biogenic amine production...

Inherently immunogenic materials offer enormous prospects in enhancing vaccine efficacy. However, the understanding and improving material adjuvanticity remain elusive. Herein how the structural presentation of immunopotentiators in a material governs the dynamic dialogue between innate and adaptive immunity for enhanced cancer vaccination is reported. The immunopotentiator manganese into six differing structures that resemble the architectures of two types of pathogens (spherical viruses or rod-like bacteria) is precisely manipulated...

BACKGROUND AND OBJECTIVE: The most frequently seen intra-oral soft tissue is the gingiva. Most often, it is seen as coral-pink tissue that surrounds the neck of the teeth. Gingiva that encircles the tooth necks and covers the alveolar processes of the jaws is an intra-oral tissue that exhibits biomimetic features. The wide range of colors of the gingiva depends on the configuration of gingival vascularity, the degree of epithelial cornification, level of melanogenesis, and the depth of epithelialization...
