Influence of temperature and cumulative strain on microstructure and mechanical properties of multi-directional forged Mg-Gd-Y-Zn-Zr alloy

open access: yesJournal of Materials Research and Technology
The multidirectional forging (MDF) experiments of Mg-Gd-Y-Zn-Zr alloy were performed. The effects of temperature and cumulative strain on microstructure and mechanical properties of multi-directional forged Mg-Gd-Y-Zn-Zr alloy were studied.

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

open access: yesAndrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

Disordered Bile Acid Metabolism in Alcohol‐Related Hepatitis

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
Serum conjugated primary bile acids accumulate in alcohol‐related hepatitis due to downregulation of hepatocyte bile acid transporters. Hepatocyte growth factor is elevated in alcohol‐related hepatitis and downregulates BSEP expression. This detrimentally affects the hepatoprotective adaptive reduction in NTCP/increase in BSEP seen in cholestasis ...

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

open access: yesArchaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Filtering of the absolute value of photon-number difference for two-mode macroscopic quantum superpositions

open access: yes, 2012
We discuss a device capable of filtering out two-mode states of light with mode populations differing by more than a certain threshold, while not revealing which mode is more populated. It would allow engineering of macroscopic quantum states of light in

Clinical Characterization of Patients With 5q Spinal Muscular Atrophy Types 2 and 3 in Brazil: A Cross‐Sectional Observational Study

open access: yesClinical Genetics, EarlyView.
This study describes the clinical heterogeneity of Brazilian patients with 5q spinal muscular atrophy types 2 and 3, highlighting prolonged diagnostic delays and the impact of disease duration on motor function. Early genetic diagnosis and access to multidisciplinary care are crucial to preserve functional outcomes.
