Effects of different hypoxia exposure on myeloid-derived suppressor cells in mice

Experimental and Molecular Pathology
For many people living at high altitudes for long or short periods of time, hypoxia is a challenge affecting many aspects of the body, including the immune system.

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Early Expansion of Monocytic Myeloid-Derived Suppressor Cells Predicts Survival in Sepsis and Is Possibly Associated With Activation of Endoplasmic Reticulum Stress Pathways

Frontiers in Bioscience-Landmark
Background:Sepsis is characterized by profound immune dysregulation, in which myeloid-derived suppressor cells (MDSCs) serve as key regulators of the host immune response.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Wide distribution and altitude correlation of an archaic high-altitude-adaptive EPAS1 haplotype in the Himalayas.

, 2016
High-altitude adaptation in Tibetans is influenced by introgression of a 32.7-kb haplotype from the Denisovans, an extinct branch of archaic humans, lying within the endothelial PAS domain protein 1 (EPAS1), and has also been reported in Sherpa.

Prevalence of gallstone disease and its association with altitude and ethnicity among employee health check-upers in the Qinghai-Tibet Plateau

BMC Gastroenterology
Objective This study aimed to investigate the prevalence of gallstone disease among health check-upers (employees) in the Qinghai-Tibet Plateau and clarify the independent effects of altitude, ethnicity, and their interaction on gallstone disease risk ...

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Hypoxia promotes progression of cervical cancer by modulating the ATXN3-enhanced P53 stability or STAT5 phosphorylation

Cell Death Discovery
This study examines hypoxia’s role in regulating ATXN3 (ATXN3) across cervical cancer subtypes and its impact on tumor progression. We analyzed ATXN3 expression in clinical samples and cell lines (C33A, HeLa, SiHa), assessing proliferation/migration ...
