Impurity detection is an important link in the chain of food processing. Taking walnut kernels as an example, it is difficult to accurately detect impurities mixed in walnut kernels before the packaging process. In order to accurately identify the small impurities mixed in walnut kernels, this paper established an improved impurities detection model based on the original YOLOv5 network model. Initially, a small target detection layer was added in the neck part, to improve the detection ability for small impurities, such as broken shells...

INTRODUCTION: The scope of practice for pharmacy technicians is expanding to include vaccine administration in some provinces. Vaccine training courses and programs currently do not include education about mitigating immunization stress-related responses (ISRR) and improving the vaccination experience. We obtained feedback from pharmacy technician students about a new e-module that addresses this identified knowledge gap, whereby learners are educated about CARD (Comfort Ask Relax Distract), a vaccine delivery framework that reduces ISRR and improves the vaccination experience...

OBJECTIVE: Aberrant responses to frustration are central mechanisms of pediatric irritability, which is a common reason for psychiatric consultation and a risk factor for affective disorders and suicidality. This pilot study aimed to characterize brain network configuration during and after frustration and test whether characteristics of networks formed during or after frustration relate to irritability. METHOD: During functional magnetic resonance imaging, a transdiagnostic sample enriched for irritability (N = 66, mean age = 14...

AIM: To explore the features of vectorcardiograms (VCG) of patients with essential hypertension complicated by chronic heart failure with reduced left ventricular ejection fraction (CHFrLVEF). MATERIALS AND METHODS: We analyzed VCGs of 70 hypertensive patients with CHFrLVEF and 275 hypertensive patients without clinical signs of CHF and with LVEF50%. We assessed the presence of rhythm and conduction disturbances, and the parameters of the synthesized VCG, i.e., module of the maximum QRS vector, planarity index of the spatial QRS loop (P/S), and spatial angle between the integral QRS and T vectors (sQRS-Ta)...

Context: The shift to digital learning in medicine is well underway and in fact spurred by the COVID-19 pandemic. The didactic portion of our institution's cytotechnology (CT) education program is online and delivered to learners across the nation. With CT education elevating to the master's degree level, there is a need to expand cytologic correlation with surgical resection specimens. We also wanted to afford pathology residents the same. Methods: We developed an online cytologic-histologic correlation digital learning module (e-module) addressing thyroid fine needle aspirations (FNAs) and surgical thyroidectomy specimens which was administered as part of coursework in the CT education and pathology residency programs...

The aim of this study was to assess the effects of a mixture of four dietary fibres on obese rats. Four groups of male Wistar rats were fed with either standard chow (STD) or cafeteria diet (CAF) and were orally supplemented with either fibre mixture (2 g kg-1 of body weight) (STD+F or CAF+F groups) or vehicle (STD+VH or CAF+VH groups). We studied a wide number of biometric, biochemical, transcriptomic, metagenomic and metabolomic variables and applied an integrative multivariate approach based on multiple factor analysis and Pearson's correlation analysis...

Mitochondrial ATP synthase forms stable dimers arranged into oligomeric assemblies that generate the inner-membrane curvature essential for efficient energy conversion. Here, we report cryo-EM structures of the intact ATP synthase dimer from Trypanosoma brucei in ten different rotational states. The model consists of 25 subunits, including nine lineage-specific, as well as 36 lipids. The rotary mechanism is influenced by the divergent peripheral stalk, conferring a greater conformational flexibility. Proton transfer in the lumenal half-channel occurs via a chain of five ordered water molecules...

How does the central nervous system (CNS) control our bodies, including hundreds of degrees of freedom (DoFs)? A hypothesis to reduce the number of DoFs posits that the CNS controls groups of joints or muscles (i.e., modules) rather than each joint or muscle independently. Another hypothesis posits that the CNS primarily controls motion components relevant to task achievements (i.e., task-relevant components). Although the two hypotheses are examined intensively, the relationship between the two concepts remains unknown, e...

This multi-institutional pilot study describes the experience among nephrology trainees, of using a faculty-developed interactive E-curriculum in hemodialysis (HD) and examines its impact on learner knowledge and satisfaction. STUDY DESIGN: A sequential mixed method design was developed for curriculum assessment, using a survey tool and 1 : 1 interview...

Experimental evidence in animals demonstrates cortical neurons innervate subcortex bilaterally to tune brainstem auditory coding. Yet, the role of the descending (corticofugal) auditory system in modulating earlier sound processing in humans during speech perception remains unclear. Here, we measured EEG activity as listeners performed speech identification tasks in different noise backgrounds designed to tax perceptual and attentional processing. Brainstem speech coding might be tied to attention and arousal states (indexed by cortical α power) that actively modulate the interplay of brainstem-cortical signal processing...

Growth-related abnormalities affecting modern chickens, known as White Striping (WS) and Wooden Breast (WB), have been deeply investigated in the last decade. Nevertheless, their precise etiology remains unclear. The present study aimed at providing new insights into the molecular mechanisms involved in their onset by identifying clusters of co-expressed genes (i.e., modules) and key loci associated with phenotypes highly related to the occurrence of these muscular disorders. The data obtained by a Weighted Gene Co-expression Network Analysis (WGCNA) were investigated to identify hub genes associated with the parameters breast width (W) and total crude protein content (PC) of Pectoralis major muscles (PM) previously harvested from 12 fast-growing broilers (6 normal vs ...

During the COVID-19 pandemic, academic health centers suspended clinical clerkships for students. A need emerged for innovative virtual curricula to continue fostering professional competencies. In March 2020, a multidisciplinary team from the University of Nebraska Medical Center had 2 weeks to create a course on the impact of infectious diseases that addressed the COVID-19 pandemic in real time for upper-level medical and physician assistant students. Content addressing social determinants of health, medical ethics, population health, service learning, health security, and emergency preparedness were interwoven throughout the course to emphasize critical roles during a pandemic...

PURPOSE: This paper focused on the design and optimization of ridge filter-based intensity-modulated proton therapy (IMPT), and its potential applications for FLASH. Differing from the standard pencil beam scanning (PBS) mode, no energy/layer switching is required and total treatment time can be shortened. METHODS: Unique dose influence matrices were generated as a proton beam traverse through slabs of different thicknesses (i.e. modulation by different layers)...

INTRODUCTION: Medical school faculty and administrators regularly assess sentiment in student-generated textual data, such as instructor and course evaluations. Machine learning models (MLMs) that automate and systematize sentiment analysis are commercially available. However, the congruency of MLMs has not been extensively tested. We compare sentiment polarity derived from human analysis and five MLMs to test the hypothesis they yield significantly correlated output. METHODS: Student evaluations (n=116) of the neuroscience module at the UCF College of Medicine were collected and anonymized...

INTRODUCTION: The Master of Occupational Therapy (MScOT) program at Western University attracts students from diverse backgrounds, including those from non-science fields. As anatomical competency is essential for effective patient management and safe practice, students in this Master's program are required to complete training in anatomy. However, past student feedback had indicated that those with no prior experience in anatomy struggled with basic anatomical concepts, as limited time is allotted to foundational anatomical knowledge in the first year of the curriculum...

Of necessity for a practicing Occupational Therapist is the ability to demonstrate competent neuroanatomical knowledge through application into clinical practice. Yet, throughout the academic careers of Occupational Therapy (OT) students, neuroanatomy (NA) will consistently be perceived as one of the most difficult anatomical topics encountered. Rising in anatomical education is the use of computer assisted learning (CAL) due to its alignment with educational goals and student desires. This study aims to determine how neuroanatomy e-modules (NEMs) can improve the perceptions and academic performance in NA of first year Master of Occupational Therapy (MScOT) students at Western University...

Nitric oxide (NO) is a short-lived gas that acts as a signaling molecule in all higher organisms, including plants. Despite the involvement of NO in multiple plant processes, including germination, root growth and fertility, a basic understanding of the mechanisms by which NO exerts its effects is lacking. NO and its derivatives impact these physiological processes through reversible S-nitrosation of critical protein cysteines. In cells, regulation of NO-levels is predominantly achieved by reaction of reactive nitrogen species (RNS) with glutathione (GSH), thereby forming S-nitrosoglutathione (GSNO), a principal NO reservoir...

In plants, nitric oxide (NO) is a crucial signaling molecule involved in many physiological processes and stress pathways. NO can influence plant germination, flowering, and root development1 . NO is usually found in an adduct with glutathione, forming S-nitrosoglutathione (GSNO), which can affect protein S-nitrosation, an important post-translational modification that can alter protein activity and stability. The enzyme S-nitrosoglutathione reductase (GSNOR) catalyzes the irreversible NADH-dependent reduction of GSNO...

Introduction Preventing errors in donning and doffing of personal protective equipment (PPE) is critical for limiting the spread of infectious diseases. Virtual reality (VR) has demonstrated itself as an effective tool for asynchronous learning, but its use in PPE training has not been tested. The objective of this study was to compare donning and doffing performance between VR and e-module PPE training. Methods A prospective randomized open-blinded controlled trial was conducted to determine differences in donning and doffing performance after VR and e-module PPE training among medical staff and medical students at a single institution...
