High altitude medicine

Medical Clinics of North America, 1992
Altitude illness is common and may result in major disruption of travel plans. Visitors to altitude need to be aware of the various health problems they might encounter and how they may be prevented. Self-diagnosis and treatment is the norm in many remote locations.

Assessment of the Brainstem- Mediated Stapedius Muscle Reflex in Andean Children Living at High Altitudes

, 2017
This study examined the physiological thresholds, amplitude growth, and contraction duration of the acoustic stapedius reflex (ASR) in Andean children aged 2-17 years living at altitudes of 2850m (Altitude I Group) and 3973m (Altitude II Group) as part ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Do High Temperatures Affect Firm Demography? Evidence From Italy

Business Strategy and the Environment, EarlyView.
ABSTRACT This study analyses the impact of high temperatures and heat stress on Italian firm demography during 2009–2022. Combining provincial‐firm‐level data with a high‐resolution multidecadal meteorological dataset, we investigate whether high temperatures—absolute and anomalous—affect firm entry and exit rates.

Impact of Drone Versus Car Transport on Anti‐Doping Sample Integrity Over Short Distances: A Proof‐Of‐Concept Study

Drug Testing and Analysis, EarlyView.
This proof‐of‐concept study evaluated the impact of short‐distance drone transport on anti‐doping sample integrity compared with traditional car transport. Targeted assays and untargeted metabolomics revealed equivalent biological profiles between methods, confirming that drone delivery preserves sample integrity for the athlete biological passport ...

Red Blood Cell Surface Proteins and Cryopreservation for Tracking Altered Erythropoiesis

Drug Testing and Analysis, EarlyView.
Recombinant human erythropoietin altered red blood cell surface protein expression, but responses were inconsistent and accompanied by substantial baseline variability. Although cryopreservation reduced analytical variability, it did not improve biomarker performance, indicating limited utility for detecting altered erythropoiesis. ABSTRACT The present

Dynamic geo‐hydrogeological monitoring‐driven situational awareness for real‐time floor water inrush risk prediction in deep mining

Deep Underground Science and Engineering, EarlyView.
The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).
