Left ventricular rigor mortis interferes with postmortem aortic root geometry.

Aortic regurgitation is a common valve disease and can be caused by delineated findings such as fenestrations or hardly discernible alterations of the aortic root geometry. Therefore, aortic regurgitation can be a challenging diagnosis during an autopsy. Cardiac surgeons, however, are confronted with comparable problems during surgery and have developed a refined knowledge of the anatomy of the aortic root including its geometry.

Ultra-stable transportable ultraviolet clock laser using cancellation between photo-thermal and photo-birefringence noise.

Optical clocks require an ultra-stable laser to probe and precisely measure the frequency of the narrow-linewidth clock transition. We introduce a portable ultraviolet (UV) laser system for use in an aluminum quantum logic clock, demonstrating a fractional frequency instability of approximately mod   = 2 × 10. The system is based on an ultra-stable cavity with crystalline AlGaAs/GaAs mirror coatings, with a frequency quadrupling system employing two single-pass second-harmonic generation (SHG) stages.

Examining Gravettian and Magdalenian mobility and technological organization with IR spectroscopy.

Archaeologists can use the provenance of lithic raw materials to examine the movements, territories, and settlement dynamics of hunter-gatherers. Several studies have used macroscopic analyses to propose the long-distance transport of raw material during the Gravettian and the Magdalenian of the Swabian Jura in Central Europe. Until now hypotheses about raw material transport in this region were not based on reproducible analyses.

Differentially expressed messenger RNA isoforms in beef cattle skeletal muscle with different fatty acid profiles.

This study aimed to identify mRNA isoforms that were expressed differently in the muscle tissue of Nellore cattle based on their intramuscular fatty acid profile. Forty-eight young bulls were used to quantify beef fatty acids (FA) and perform RNA sequencing analysis. The young bulls were divided into three different groups based on quantifying FA using k-means analysis.

Association Between Unemployment and Mental Disorders: A Narrative Update of the Literature.

The relationship between unemployment and mental disorders has been a significant subject of study since at least the Industrial Revolution. However, most data show associations of unemployment and isolated mental disorders, and this study field has been neglected in the last years. Therefore, this narrative review aims to provide an updated overview of the association between unemployment and mental health in general as well as the most prevalent mental disorders.
