Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.

Toward Free‐Breathing Renal CEST MRI: Preclinical Evaluation of a Novel Prospective Respiratory Triggering Approach

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1333-1341, September 2026.
ABSTRACT Purpose Endogenous renal chemical exchange saturation transfer (CEST) imaging enables contrast‐agent‐free assessment of renal metabolism but is highly sensitive to respiratory motion. Existing approaches, such as timed breathing, require high patient compliance or preclinical mechanical ventilation, limiting clinical translation.

Association of Testosterone With Lean Soft Tissue and Handgrip Strength Across Middle‐Aged Men

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Testosterone declines by 0.4%–2% annually after the age of 30 and is potentially linked with muscle mass and strength. This study examined how testosterone levels are associated with handgrip strength (HGS) and appendicular lean soft tissue index (ALSTI) in men aged 40–49 and 50–59 years.
