The relationship between altitude and hail frequency in the Transvaal

, 1988
Correlations of hail incidence with major topographical features have been documented for various parts of the world. The relationship, however, not necessarily a linear one.

Inspiratory muscle training and its effect on indices of physiological and perceived stress during incremental walking exercise in normobaric hypoxia

, 2014
This study evaluated the effects of inspiratory muscle training (IMT) on inspiratory muscle fatigue (IMF) and physiological and perceptual responses during trekking-specific exercise. An 8-week IMT program was completed by 21 males (age 32.4 – 9.61 years,

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

Advanced 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.

Association Between Plasma N-Acylethanolamides and High Hemoglobin Concentration in Southern Peruvian Highlanders

, 2017
High-altitude (HA) hypoxia is a stressful condition endured by organisms through different mechanisms. Failing to adapt to chronic HA exposure leads to a disease called chronic mountain sickness (CMS) characterized by excessive erythrocytosis (hemoglobin

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

American 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 ...

Assessing the Feasibility of Wearable Devices for Physiological Monitoring and Heat Risk Prediction in Outdoor Agricultural Workers

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Outdoor agricultural workers experience significant heat exposure, yet few studies have evaluated whether wearable sensors can reliably measure continuous physiological responses in real field conditions. This pilot study examined the feasibility and predictive utility of core temperature, hydration, heart rate, and movement data ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

Applications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the
