Increasing obstructive sleep apnea risk is associated with hearing impairment in middle-aged Chinese men—A cross-sectional study

Plos.org 
En

by Yu Li, Xiaoyi Wang, Jing Cui, Jiping Ren, Zhong Xin, Dongning Chen

Objective

Midlife males with obstructive sleep apnea (OSA) bear a high risk for cardiovascular diseases. However, the association of OSA and hearing impairment is controversial. Our objective was to observe the incidence of hearing loss in middle-aged males with different risks for OSA.

Methods

794 men aged 40–65 who participated in health examination and pure tone hearing screening between January and June 2021 were recruited in the study. Читать дальше...

Spatial variation in food web structure in a recovering marine ecosystem

En

by Kyle J. Krumsick, Jonathan A. D. Fisher

Spatial heterogeneity in food web structure and interactions may reconcile spatial variation in population and community dynamics in large marine ecosystems. In order to assess food web contributions to the different community recovery dynamics along the Newfoundland and Labrador shelf ecosystem, we quantified species interactions using stable isotope mixing models and food web metrics within three sub-regions. Representative samples of each species... Читать дальше...

A parametric numerical analysis of femoral stem impaction

En

by Nicholas E. Bishop, Phil Wright, Martin Preutenborbeck

Press-fitted implants are implanted by impaction to ensure adequate seating, but without overloading the components, the surgeon, or the patient. To understand this interrelationship a uniaxial discretised model of the hammer/introducer/implant/bone/soft-tissues was developed. A parametric analysis of applied energy, component materials and geometry, and interactions between implant and bone and between bone and soft-tissues was performed... Читать дальше...

Estimating the total prevalence of PTSD among the UK police force: Formal comment on Stevelink et al. (2020)

by Chris R. Brewin, Jessica K. Miller, Brendan Burchell

Two recent surveys have reported widely differing prevalence rates for posttraumatic stress disorder (PTSD) within the U.K. police force. Stevelink et al. (2020) reported a rate of 3.9% whereas a survey conducted for the charity Police Care UK reported a rate of 20.6%. In this comment we discuss how definitions and methodological factors can impact prevalence rates. We consider a number of possible reasons for the discrepancy between the surveys...

The mechanical role of the metatarsophalangeal joint in human jumping

En

by Junichiro Yamauchi, Keiji Koyama

This study investigated the mechanical role of metatarsophalangeal (MTP) joints in human jumping. Eighteen healthy young men performed three types of single-leg jumps (SJ: squat jump; CMJ: countermovement jump; HJ: standing horizontal jump) on a force plate under barefoot (BARE) and forefoot immobilisation (FFIM) conditions. For FFIM, the forefoot was immobilised around the MTP joints of the dominant leg by a custom-made splint. Force-time components and... Читать дальше...

Do patients’ pre-treatment expectations about acupuncture effectiveness predict treatment outcome in patients with chronic low back pain? A secondary analysis of data from a randomised controlled clinical trial

Plos.org 
En

by Anja Zieger, Alexandra Kern, Jürgen Barth, Claudia M. Witt

Objective

This secondary analysis of a randomised controlled patient-blinded trial comparing effectiveness and side effect briefings in patients with chronic low back pain (CLBP) investigated the association between patients’ pre-treatment expectations about minimal acupuncture treatment and pain intensity as outcome during and after the end of the treatment.

Methods

Chronic low back pain patients with a pain intensity... Читать дальше...

Impact of the twin pandemics: COVID-19 and oil crash on Saudi exchange index

En

by Dania AL-Najjar

This study aims to explore the effects of COVID-19 indicators and the oil price crash on the Saudi Exchange (Tadawul) Trading Volume and Tadawul Index (TASI) for the period from January 1, 2020, to December 2, 2020. The independent variable is oil price, and the COVID-19 indicators are lockdown, first and second decreases of Repo and Reverse Repo rates, Saudi government response, and cumulative deceased cases. The study adopts two phases. In the first phase, linear regression... Читать дальше...

Sensing spectrum sharing based massive MIMO radar for drone tracking and interception

En

by Milembolo Miantezila Junior, Bin Guo

Radar sensors are becoming crucial for environmental perception in a world with the tremendous growth of unmanned aerial vehicles (UAVs) or drones. When public safety is a concern, the localization of drones are of great significance. However, a drone used for a wrong motive can cause a serious problem for the environment and public safety, given the fact that the dynamic movement of a drone’s emission signal and location tracking is different from existing positioning.

Effects of arsenic on the topology and solubility of promyelocytic leukemia (PML)-nuclear bodies

Plos.org 
En

by Seishiro Hirano, Osamu Udagawa

Promyelocytic leukemia (PML) proteins are involved in the pathogenesis of acute promyelocytic leukemia (APL). Trivalent arsenic (As3+) is known to cure APL by binding to cysteine residues of PML and enhance the degradation of PML-retinoic acid receptor α (RARα), a t(15;17) gene translocation product in APL cells, and restore PML-nuclear bodies (NBs). The size, number, and shape of PML-NBs vary among cell types and during cell division. However, topological... Читать дальше...
