Background And Purpose: Tai Chi is a mind-body exercise that has been shown to improve both mental and physical health. As a result, recent literature suggests the use of Tai Chi to treat both physical and psychological disorders. However, the underlying physiological changes have not been characterized. The aim of this pilot study is to assess the changes in brain metabolites and muscle energetics after Tai Chi training in an aging population using a combined brain-muscle magnetic resonance spectroscopy (MRS) examination.
Methods: Six healthy older adults were prospectively recruited and enrolled into a 12-week Tai Chi program. A brain H MRS and a muscle P MRS were scanned before and after the training, and postprocessed to measure N-acetylaspartate to creatine (NAA/Cr) ratios and phosphocreatine (PCr) recovery time. Wilcoxon-signed rank tests were utilized to assess the differences between pre- and post-Tai Chi training.
Results: A significant within-subject increase in both the NAA/Cr ratios (P = .046) and the PCr recovery time (P = .046) was observed between the baseline and the posttraining scans. The median percentage changes were 5.38% and 16.51% for NAA/Cr and PCr recovery time, respectively.
Conclusions: Our pilot study demonstrates significant increase of NAA/Cr ratios in posterior cingulate gyrus and significantly improved PCr recovery time in leg muscles in older adults following short-term Tai Chi training, and thus provides insight into the beneficial mechanisms.

Olfaction mediated by the antennae is a vital sensory modality for arthropods and could be applied as a tool in pest control. The ectoparasitic mite poses a significant threat to the health of the honey bee worldwide and has garnered global attention. To better understand the chemical ecology of this host-parasite relationship, we collected and characterized the volatile organic compounds (VOCs) from and used electroantennography (EAG) to record the responses of honey bee ( and ) antennae to the different VOCs.

Unlabelled: The global prevalence of sedentary lifestyles and the associated health risks, such as cardiovascular, metabolic and mental issues, is an epidemic worldwide problem, particularly in the university population.
Background/objectives: University students are particularly vulnerable because of academic pressure and lifestyle changes. Despite the well-known benefits of physical activity in reducing mental stress and improving physical and mental well-being, the literature lacks effective interventions and standardized protocols for this population.

Programmed cell death protein-1 (PD-1) inhibitors plus chemotherapy have been the standard of care in the first-line treatment of advanced gastric or gastroesophageal junction (G/GEJ) adenocarcinoma; however, the survival benefits are modest in patients with low programmed death ligand 1 (PD-L1) expression. Here we investigated the efficacy and safety of cadonilimab (PD-1/cytotoxic T lymphocyte antigen-4 (CTLA-4) bispecific antibody) plus chemotherapy as first-line treatment in G/GEJ adenocarcinoma. The prespecified interim analysis is reported here.

Background: Preeclampsia (PE) is a serious condition characterized by hypertension and proteinuria after 20 weeks of gestation. The exact cause of PE is unknown but may involve abnormalities in the renin-angiotensin-aldosterone system (RAAS) and endothelial nitric oxide synthase (eNOS). Genetic variations in angiotensinogen (AGT), angiotensin-converting enzyme (ACE), and eNOS genes have been associated with PE.
