Bioactive compound combinations from Rhodiola tangutica alleviate pulmonary vascular remodeling in high-altitude pulmonary hypertension rats through the PI3K–AKT pathway

open access: yesFrontiers in Pharmacology
BackgroundHypoxia-induced pulmonary vascular remodeling is central to the development of high-altitude pulmonary hypertension (HAPH). Rhodiola tangutica has traditionally been used to prevent chronic mountain sickness. Although its active fraction (ACRT)

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.

Arachidonic Acid Metabolism Pathway Is Not Only Dominant in Metabolic Modulation but Associated With Phenotypic Variation After Acute Hypoxia Exposure

open access: yesFrontiers in Physiology, 2018
Background: The modulation of arachidonic acid (AA) metabolism pathway is identified in metabolic alterations after hypoxia exposure, but its biological function is controversial.

Middle Ear Function and Pathophysiology in Andean Children Living at High Altitudes

open access: yes, 2017
The extent of altitude-related middle ear disorders in children native to high altitudes is unclear. This study examined middle ear pathophysiology in two groups of children living in high-altitude Ecuadorian Andean communities by investigating middle ...

Correction of Ineffective Erythropoiesis and Normalization of Iron Homeostasis After Exagamglogene Autotemcel in Transfusion‐Dependent β‐Thalassemia

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Exagamglogene autotemcel (exa‐cel) is a one‐time, ex vivo, CRISPR‐Cas9 gene edited cell therapy approved for patients with transfusion dependent β‐thalassemia (TDT) aged 12–35 years. In a Phase 3 study (CLIMB THAL‐111), exa‐cel treatment resulted in reactivation of fetal hemoglobin and increases in total hemoglobin, leading to transfusion ...
