This two-group pretest and posttest quasi-experimental study aimed to evaluate the effects of a Tai Chi exercise programme on exercise behaviour and blood pressure (BP) in outpatients with hypertension. The experimental group (n = 27) received the Yang-style Tai Chi exercise programme three times a week for 8 weeks. The control group (n = 31) received routine care with no Tai Chi exercise. Exercise behaviour and exercise time using Routine Health Care Behaviour scale and BP were assessed at baseline and 8 weeks. The experimental group had a significant improvement on exercise behaviour (t = 2.11, P < 0.001) and exercise time (t = 1.44, P = 0.003), and a significant reduction in systolic BP (t = 2.57, P < 0.001) and diastolic BPs (t = 2.86, P < 0.001) compared with those of the control group. Tai Chi is an inexpensive and viable exercise and can improve exercise behaviour and BP control in outpatients with hypertension. Tai Chi exercise might offer outpatients with hypertension additional options, such as an adjunct to formal cardiac rehabilitation or as an exercise alternative in their management of hypertension. Nursing staff can easily learn and incorporate this exercise in patient education or care planning in the care of patients with hypertension in outpatient settings.

Interfacial Water Orientation in Neutral Oxygen Catalysis for Reversible Ampere-scale Zinc-air Batteries.

The neutral oxygen catalysis is an electrochemical reaction of the utmost importance in energy generation, storage application, and chemical synthesis. However, the restricted availability of protons poses a challenge to achieving kinetically favorable oxygen catalytic reactions. Here, we alter the interfacial water orientation by adjusting the Brønsted acidity at the catalyst surface, to break the proton transfer limitation of neutral oxygen electrocatalysis.

Background: Research suggest that mind-body movement programs have beneficial effects on cognitive outcomes for older adults with cognitive decline. However, few studies have directly compared specific approaches to mind-body movement or studied the impact of remote program delivery.
Methods: In a 3-arm randomized controlled trial (RCT) for older adults with cognitive impairment, we are comparing a multidomain mind-body program that emphasizes movement, body awareness, personal meaningfulness, and social connection, and a traditional Chinese mind-body exercise (Tai Chi) to a health and wellness education control condition.
The impact of exercise during radiotherapy on treatment-related side effects in breast cancer patients: A systematic review and meta-analysis.
Int J Nurs Stud

Department of Rehabilitation, School of Nursing, Jilin University, 965 Xinjiang Street, Chaoyang District, Changchun 130021, PR China. Electronic address:
Purpose: Radiation therapy for breast cancer often causes side effects like cancer-related fatigue, depression, and sleep disorders, impacting health-related quality of life, psychosocial aspects, and physical function. Exercise therapy is commonly used to manage cancer-related fatigue, but its effectiveness remains uncertain due to varying patient conditions and adherence. This systematic review aims to assess exercise interventions during radiotherapy for their effects on physiological and psychological side effects in breast cancer patients, clarifying efficacy and exploring different intervention types.

Electrolysis of carbon dioxide (CO2) in acid offers a promising route to overcome CO2 loss in alkaline and neutral electrolytes, but requires concentrated alkali cations (typical ≥3 M) to mitigate the trade-off between low pH and high hydrogen evolution reaction (HER) rate, causing salt precipitation. Here we report a strategy to resolve this problem by introducing tensile strain in a copper (Cu) catalyst, which can selectively reduce CO2 to valuable multicarbon products, particularly ethylene, in a pH 1 electrolyte with 1 M potassium ions. We find that the tension-strained Cu creates an electron-rich surface that concentrates diluted potassium ions, contributing to CO2 activation and HER suppression.
