Low altitude simulation without hypoxia improves left ventricular function after myocardial infarction by reducing ventricular afterload.

open access: yesPLoS ONE, 2019
Humans have a lower risk of death from myocardial infarction (MI) living at low elevations (5000 m, and intermittent hypobaric hypoxia post-MI can reduce MI size in rodents, and it is believed that hypoxia is the key stimulus.

DNA multigene characterization of Fasciola hepatica and Lymnaea neotropica and its fascioliasis transmission capacity in Uruguay, with historical correlation, human report review and infection risk analysis.

open access: yesPLoS Neglected Tropical Diseases, 2017
BackgroundFascioliasis is a pathogenic disease transmitted by lymnaeid snails and recently emerging in humans, in part due to effects of climate changes, anthropogenic environment modifications, import/export and movements of livestock.

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

open access: yesAdvanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Particle Acceleration in Pair-Starved Pulsars [PDF]

open access: yesAstrophys.J. 617 (2004) 471-479, 2004
We investigate the physical situation above the pulsar polar cap (PC) where the accelerating primaries (electrons) are not capable of producing sufficient numbers of electron-positron pairs at low altitudes (within 1-2 stellar radii above the PC surface) to screen the accelerating electric field, and continue accelerating up to, at least, very high ...

Bioinspired Liquid‐Free Ion‐Conductive Elastomers with Ultrahigh Mechanical Strength and Excellent Ionic Conductivity for Multifunctional Flexible Sensing Applications

open access: yesAdvanced Science, EarlyView.
⁻Inspired by the “brick wall” structure of pearl layer, FLICE‐110% liquid‐free ionic conductive elastomer had high mechanical strength (5.46 MPa), excellent ionic conductivity (3.29 × 10−4 S cm−1) and resilience. It can be used in smart music boxes, airplane wings and control manipulators.

Moderate Hypoxia Exposure: A Novel Strategy to Improve Glucose Metabolism in Humans? [PDF]

open access: yesEuropean Medical Journal Diabetes, 2015
The obesity epidemic calls for novel strategies to prevent and treat obesity and its comorbidities. Several studies have indicated that the amount of oxygen to which tissues are exposed may substantially impact cardiometabolic health.

Efficiency of Photovoltaic Systems in Mountainous Areas [PDF]

open access: yes2018 IEEE International Energy Conference (ENERGYCON), 2018
Photovoltaic (PV) systems have received much attention in recent years due to their ability of efficiently converting solar power into electricity, which offers important benefits to the environment. PV systems in regions with high solar irradiation can produce a higher output but the temperature affects their performance.

Radiation Hardened Infrared Photodetectors Based on a Narrow Bandgap Conjugated Polymer Semiconductor

open access: yesAdvanced Electronic Materials, EarlyView.
A blackbody‐sensitive infrared photodetector comprised of an open‐shell conjugated polymer demonstrates high sensitivity without cooling and exceptional radiation hardness, surpassing inorganic compound semiconductor devices. This functionality, inherent to the polymer semiconductor, provides a new frontier for low‐cost, size, weight, and power space ...
