Moderate anxiety may improve functional balance in older women with low muscle strength: a preliminary observation.
J Sports Med Phys Fitness
January 2025
Department of Movement, Human and Health Sciences, Foro Italico University of Rome, Rome, Italy.
Background: Anxiety commonly affects older individuals with negative consequences on various physical and motor performances such as balance. When coupled with age-related muscular strength loss, the effects on the ability to perform daily tasks could be particularly detrimental, particularly in older women who are more susceptible to anxiety, muscular strength losses and falls. The study aimed to verify the effects of anxiety on balance performance in relation to muscular strength level in healthy older women.

Background: Pancreatic damage is a common digestive system disease with no specific drugs. Static magnetic field (SMF), the key component of magnetic resonance imaging (MRI), has demonstrated prominent effects in various disease models.
Purpose: To study the effects of 0.
Frequency-dependent and capacitive tissue electrical properties in spinal cord stimulation models.
bioRxiv
November 2024
Department of Biomedical Engineering, The City College of New York, CUNY, New York, NY.
Article Synopsis
- - The study investigates how spinal cord stimulation (SCS) models that calculate electric fields (E-fields) can be more accurately represented by considering frequency-dependent properties of spinal tissues, rather than using the traditional quasi-static approximation (QSA), which overlooks important factors.
- - Researchers utilized a finite element method (FEM) to analyze E-fields for different stimulation controls and frequencies, comparing results with the QSA method across multiple locations in the spinal column and discovering that electrical properties significantly affect E-field magnitude.
- - Findings reveal that the mode of stimulation (voltage-controlled vs. current-controlled) influences the E-field's impact on spinal cord heating and waveform distortion, with voltage-controlled methods being more affected by the frequency-dependent properties than current
Patterns of Sexual Dimorphism, Static Allometry, and Modularity in the Skull of the Ethiopian White-Footed Mouse, (Rodentia: Muridae).
Zoolog Sci
December 2024
The Kyoto University Museum, Kyoto University, Kyoto 606-8501, Japan.
Article Synopsis
- - The study examined sexual dimorphism in the skull of the Ethiopian white-footed mouse using geometric morphometrics, revealing nonsignificant differences in cranial size and shape between males and females, but significant differences in mandibular size.
- - Discriminant analysis showed no notable differences in skull features between sexes, and allometric patterns were similar for both, indicating that growth patterns affected both male and female skulls similarly.
- - Overall, findings suggest sexual monomorphism in the mouse's skull, implying that factors like growth-related change and functional requirements may influence skull morphology without affecting sexual differences.
Empagliflozin prevents TNF-α induced endothelial dysfunction under flow -the potential involvement of calcium and sodium-hydrogen exchanger.
Eur J Pharmacol

Amsterdam, University Medical Centers, Department of Anesthesiology - Laboratory of Experimental Intensive Care and Anesthesiology-L.E.I.C.A, Amsterdam Cardiovascular Science, Meibergdreef 11, 1105 AZ, Amsterdam, the Netherlands. Electronic address:
Background: Empagliflozin (EMPA) attenuates inflammation-induced ROS generation in static endothelial cells through inhibition of sodium hydrogen exchanger 1 (NHE1) and modulation of ion homeostasis. We hypothesize that EMPA will alleviate TNF-α stimulated endothelial dysfunction under flow conditions, and that this might be mediated by NHE1 and intracellular Ca.
Methods: Human coronary artery endothelial cells were pre-treated with EMPA or vehicle before starting flow with or without TNF-α.
