Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Effects of Hyperbaric Hypoxia on Some Enzyme Systems in the Mammalian Liver [PDF]

open access: yes, 1978
The metabolic effects of hypobaric hypoxic stress on the mammalian liver were studied. The lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) activity of mouse liver homogenates were measured after exposure to an equivalent altitude of 36,000 ...

Angular-dependent oscillations of the magnetoresistance in Bi_2Se_3 due to the three-dimensional bulk Fermi surface

open access: yes, 2010
We observed pronounced angular-dependent magnetoresistance (MR) oscillations in a high-quality Bi2Se3 single crystal with the carrier density of 5x10^18 cm^-3, which is a topological insulator with residual bulk carriers.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

open access: yesAnimal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Quality of Life After Surgical Treatment of Head and Neck Paragangliomas

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Head and neck paragangliomas (HNPGLs) are rare neuroendocrine tumors and often arise in the head and neck. Due to their localization, the tumor and its surgical treatment pose a risk for cranial nerve impairments. Few studies have focused on the health‐related quality of life (HRQOL) in patients with HNPGLs and their relation to ...

Leveraging Medical Students’ Experiences with Social Determinants of Health During Their Pediatric Clerkship to Drive Curriculum

open access: yesJournal of Medical Education and Curricular Development
Background The relationship between social determinants of health (SDH) and negative health outcomes is well established, prompting undergraduate medical educators to teach students to recognize and address these SDH.

Radiation-induced zero-resistance states with resolved Landau levels

open access: yes, 2005
The microwave-photoexcited high mobility GaAs/AlGaAs two-dimensional electron system exhibits an oscillatory-magnetoresistance with vanishing resistance in the vicinity of magnetic fields $B = [4/(4j+1)] B_{f}$, where $B_{f} = 2\pi\textit{f}m^{*}/e$, m$^{

Beating of the oscillations in the transport coefficients of a one-dimensionally periodically modulated two-dimensional electron gas in the presence of spin-orbit interaction

open access: yes, 2004
Transport properties of a two-dimensional electron gas (2DEG) are studied in the presence of a perpendicular magnetic field $B$, of a {\it weak} one-dimensional (1D) periodic potential modulation, and of the spin-orbit interaction (SOI) described only by

Fermi surface topology and signature of surface Dirac nodes in LaBi

open access: yes, 2017
Novel topological state of matter is one of the rapidly growing fields in condensed matter physics research in recent times. While these materials are fascinating from the aspect of fundamental physics of relativistic particles, their exotic transport ...
