Prevalence, characteristics, consequences, and awareness of work-related musculoskeletal pain among cardiac sonographers compared with other healthcare workers in Saudi Arabia: A cross sectional study

Plos.org 

by Lamia Al Saikhan

Background

Evidence related to work-related musculoskeletal pain (WRMSP) among cardiac sonographers is incomplete. This study aimed to investigate the prevalence, characteristics, consequences, and awareness of WRMSP among cardiac sonographers compared with other healthcare workers in different healthcare settings in Saudi Arabia.

Methods

This was a descriptive, cross-sectional, survey-based study. An electronic self-administered survey using a modified version... Читать дальше...

Is online learning during the COVID-19 pandemic associated with increased burnout in medical learners?: A medical school’s experience

Plos.org 

by Sarah Hunt, Jenna Simpson, Lyndon Letwin, Bryan MacLeod

Introduction

The COVID-19 pandemic necessitated a shift to virtual curriculum delivery at Canadian medical schools. At the NOSM University, some learners transitioned to entirely online learning, while others continued in-person, in-clinic learning. This study aimed to show that medical learners who transitioned to exclusively online learning exhibited higher levels of burnout compared to their peers who continued in-person, clinical learning.

Etiology and outcome of penetrating keratoplasty in bullous keratopathy post-cataract surgery vs post-glaucoma surgery

Plos.org 

by Young-ho Jung, Hyuk Jin Choi, Mee Kum Kim, Joo Youn Oh

Purpose

To investigate the causes of bullous keratopathy (BK) in the Korean population and analyze the results of penetrating keratoplasty (PK) in BK eyes associated with the top two causes: pseudophakic bullous keratopathy (PBK) and glaucoma surgery-associated BK (GBK).

Methods

Medical records were reviewed of patients diagnosed with BK at a tertiary referral center between 2010 and 2020. The predisposing conditions, clinical... Читать дальше...



How does industrial intelligence affect regional innovation efficiency? Evidence from panel data of China’s provinces

Plos.org 

by Kedong Wu, Tianshan Yang, Mengchun Zhu

Innovation efficiency is an important manifestation of regional innovation capacity, and how to improve regional innovation efficiency is crucial to regional development. This study empirically explores the impact of industrial intelligence on regional innovation efficiency and the possible influence of approaches and mechanisms. The empirical results revealed the following. First, the development level of industrial intelligence can positively affect regional innovation efficiency... Читать дальше...

Love, jealousy, satisfaction and violence in young couples: A network analysis

Plos.org 

by José Ventura-León, Cristopher Lino-Cruz

In recent years, couples have been affected by health measures related to COVID-19, a circumstance that forces us to examine couple interactions in terms of crucial variables of their functioning. In this sense, the present study aimed to examine the association between love, jealousy, satisfaction, and violence in young couples through network analysis. A total of 834 young people and adults between 18 and 38 years of age (Mean = 20.97, SD = 2.39)... Читать дальше...

Genetic variation in chromatin state across multiple tissues in Drosophila melanogaster

Plos.org 

by Khoi Huynh, Brittny R. Smith, Stuart J. Macdonald, Anthony D. Long

We use ATAC-seq to examine chromatin accessibility for four different tissues in Drosophila melanogaster: adult female brain, ovaries, and both wing and eye-antennal imaginal discs from males. Each tissue is assayed in eight different inbred strain genetic backgrounds, seven associated with a reference quality genome assembly. We develop a method for the quantile normalization of ATAC-seq fragments and test for differences in coverage among genotypes... Читать дальше...

Bacillus subtilis encodes a discrete flap endonuclease that cleaves RNA-DNA hybrids

Plos.org 

by Frances Caroline Lowder, Lyle A. Simmons

The current model for Okazaki fragment maturation in bacteria invokes RNA cleavage by RNase H, followed by strand displacement synthesis and 5′ RNA flap removal by DNA polymerase I (Pol I). RNA removal by Pol I is thought to occur through the 5′-3′ flap endo/exonuclease (FEN) domain, located in the N-terminus of the protein. In addition to Pol I, many bacteria encode a second, Pol I-independent FEN. The contribution of Pol I and Pol I-independent... Читать дальше...

XRN2 suppresses aberrant entry of tRNA trailers into argonaute in humans and Arabidopsis

Plos.org 

by Briana Wilson, Zhangli Su, Pankaj Kumar, Anindya Dutta

MicroRNAs (miRNAs) are a well-characterized class of small RNAs (sRNAs) that regulate gene expression post-transcriptionally. miRNAs function within a complex milieu of other sRNAs of similar size and abundance, with the best characterized being tRNA fragments or tRFs. The mechanism by which the RNA-induced silencing complex (RISC) selects for specific sRNAs over others is not entirely understood in human cells. Several highly expressed... Читать дальше...

Matrix prior for data transfer between single cell data types in latent Dirichlet allocation

Plos.org 

by Alan Min, Timothy Durham, Louis Gevirtzman, William Stafford Noble

Single cell ATAC-seq (scATAC-seq) enables the mapping of regulatory elements in fine-grained cell types. Despite this advance, analysis of the resulting data is challenging, and large scale scATAC-seq data are difficult to obtain and expensive to generate. This motivates a method to leverage information from previously generated large scale scATAC-seq or scRNA-seq data to guide our analysis of new scATAC-seq datasets. We... Читать дальше...

A convolutional neural network provides a generalizable model of natural sound coding by neural populations in auditory cortex

Plos.org 

by Jacob R. Pennington, Stephen V. David

Convolutional neural networks (CNNs) can provide powerful and flexible models of neural sensory processing. However, the utility of CNNs in studying the auditory system has been limited by their requirement for large datasets and the complex response properties of single auditory neurons. To address these limitations, we developed a population encoding model: a CNN that simultaneously predicts activity of several hundred neurons recorded during presentation of a large set of natural sounds.
