, MRT-measured point-SAR values did not exceed the system-predicted SAR

in either the uniform phantom or in the piece of meat mimicking the wrist located at the SAR hotspot location.

A highly accurate MRT technique with high spatial and temporal resolution was developed. This technique can be used to ensure that system-predicted SAR values are not exceeded in practice, thereby providing independent validation of SAR levels delivered by a newly built RF wrist coil. The MRT technique is readily generalizable to perform safety evaluations for other RF coils at 7T.

First, to examine the factors from maternal characteristics and medical history that affect maternal cardiovascular indices, and, second, to examine the potential value of maternal cardiovascular indices at 19-23 weeks' gestation, on their own and in combination with maternal factors and the established biomarkers of pre-eclampsia (PE), including uterine artery pulsatility index (UtA-PI), mean arterial pressure (MAP), serum placental growth factor (PlGF) and serum soluble fms-like tyrosine kinase-1 (sFlt-1), in the prediction of subsequent development of PE.

This was a prospective observational study in women attending for a routine hospital visit at 19 + 1 to 23 + 3 weeks' gestation. This visit included recording of maternal demographic characteristics and medical history, assessment of maternal E/A ratio, E/e' ratio, myocardial performance index, global longitudinal systolic strain, left ventricular ejection fraction, peripheral vascular resistance, left ventricular cardiac output and left ventricular mund in Obstetrics and Gynecology.

Assessment of maternal cardiovascular function provides information on the pathophysiology of PE but is not useful in the prediction of PE. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.There is growing interest in far-UVC lighting, defined as wavelengths from 200 to 230 nm, because research has demonstrated these wavelengths to be an effective antimicrobial technology while posing a minimal hazard to human health. Far-UVC lighting is now being installed to directly irradiate spaces where humans are present, and it will be important to perform measurements to verify far-UVC lighting installations are operating within widely accepted exposure guidelines. In this work, we explore the use of a commercially available film, known as OrthoChromic OC-1, to measure ultraviolet radiation exposure. The film was tested with a variety of ultraviolet wavelengths and irradiance conditions, and the color change of the film was analyzed for increasing levels of radiant exposure. The film response extended over a dynamic range that was greater than the recommended exposure limits for far-UVC radiation so it can potentially be useful for health hazard monitoring. The spectrum of the incident ultraviolet radiation strongly affected the response of the film; therefore, for accurate measurements we recommend the measured spectrum match the spectrum used for calibration. Overall, dosimetry with this film provides a simple, accurate, and inexpensive method of quantifying ultraviolet radiation exposure that is suitable for far-UVC measurements.

The present study aimed to determine the depression risk and the management of chronic diseases of individuals over 65 years old under the mandatory mass coronavirus disease 2019 quarantine.

The cross-sectional study was conducted with 185 Turkish elders with chronic diseases.

The majority of the elderly reported that their medication, diet, and exercise programs were not affected, but the regular health controls were negatively affected. Of the participants, 51.9% of them carried the risk of depression.

Urgent action plans for elders need to be developed taking into account psychosocial needs for them to pass the pandemic process with minimal damage.

Hirschsprung disease (HSCR), characterized by the defective migration of enteric neural crest cells, is a severe congenital tract disease in infants. Its etiology is not clear at present, although a genetic component plays an important role in its etiology. Many studies focused on the polymorphisms of microRNA (miRNA) in several disease progressions have been reported, including HSCR. However, the findings remain inconclusive. this website The present study aimed to explore the association of genetic variants in miRNAs and HSCR susceptibility in Southern Chinese children.

Five single nucleotide polymorphisms (SNPs) (miR-146A rs2910164, miR-4318 rs8096901, miR-3142 rs2431697, miR-3142 rs2431097 and miR-3142 rs5705329) were included to be genotyped in the stratified analysis through the Mass ARRAY iPLEX Gold system (Sequenom, San Diego, CA, USA) conducted on all the samples, comprising 1470 cases and 1473 controls. After quality control, the minor allele frequency was compared in cases and controls to analyze the association between SNPs and HSCR using PLINK 1.9 (https//www.cog-genomics.org/plink) and multiple heritability models were tested (additive, recessive and dominant models).

Our results indicated that miR-4318 rs8096901 polymorphisms were associated with HSCR susceptibility in Southern Chinese children, especially in short-segment HSCR (S-HSCR) patients after stratified analysis.

In summary, we report that miR-4318 rs8096901 was associated with HSCR, especially in SHSCR patients.

In summary, we report that miR-4318 rs8096901 was associated with HSCR, especially in SHSCR patients.CTP synthase (CTPS) cytoophidia have been found in many species over domains of life in the past 10 years, implying the evolutionary conservation of these structures. However, there are differences in cytoophidia between species. The difference in CTPS cytoophidium properties between budding yeast (Saccharomyces cerevisiae) and fission yeast (Schizosaccharomyces pombe) inspires this research. We study the effects of culture environment on cytoophidia in S. cerevisiae by switching to the optimal medium for S. pombe. S. cerevisiae CTPS cytoophidium fragmentation and pseudohyphae formation are observed after treatment with S. pombe medium YES instead of S. cerevisiae medium YPD. By modifying the level of each ingredient of the media, we find that hypoosmolality impedes cytoophidium integrity during nitrogen starvation. Our study demonstrates the relationship between cytoophidium integrity and environmental stress, supporting the role of cytoophidia in stress resistance.
