Purpose: This study aimed to examine the effect of home-based pulmonary rehabilitation (PR) on bone mineral density (BMD), lung function, dyspnea, and walking ability for stable Chronic Obstructive Pulmonary Disease (COPD) patients with OP (osteoporosis).
Methods: The required sample size was 27 per group, adjusted to 32 per group to account for a 15% dropout rate, ensuring 90% power. This is a 6-month randomized, single-blind, controlled trial. COPD patients with OP were randomly divided into the home-based PR and control groups. Patients in the control group received the program of health education and drug treatment. Patients in the home-based PR group received additional home-based PR programs. The primary outcome was the bone mineral density (BMD) at the lumbar spine. The secondary outcomes included BMD at the femoral neck, lung function (FEV% and FEV/FVC), the modified Medical Research Council (mMRC), COPD assessment test (CAT), Borg dyspnea scale (Borg), and Six-minute walk distance test (6MWT). All outcomes were assessed at 3 and 6 months.
Results: After 6 months, 29 patients in the home-based PR group and 28 in the control group completed the trial. The BMD of the lumbar spine and femoral neck in the home-based PR group was significantly higher than that in the control group (0.758 ± 0.048 vs. 0.728 ± 0.057, p = 0.031, 0.670 ± 0.024 vs. 0.658 ± 0.019, p = 0.039, respectively). There was no significant difference in FEV% and FEV/FVC between the groups. The mMRC, CAT, and Borg of the home-based PR group were significantly lower than those of the control group at 3 and 6 months (p < 0.05). The 6MWT of the home-based PR group was significantly higher than that of the control group at 3 and 6 months (p < 0.05).
Conclusions: Home-based PR improved BMD, dyspnea, symptoms, function, and daily living ability but not lung function in COPD patients with OP.

Background: Knee osteoarthritis (KOA) is a prevalent degenerative joint disorder that significantly impairs physical function and daily activities. While conventional treatments focus on symptom management, complementary therapies such as aromatherapy massage have gained attention for their potential benefits.
Objective: This study evaluates the effects of peppermint oil aromatherapy massage on functional impairments in KOA patients.

Embryo transfer (ET) is a valuable reproductive technology in pigs, albeit its efficiency remains significantly lower than that of natural mating or artificial insemination (AI), owing to high embryonic death rates. Critical for embryo survival and pregnancy success is the placenta, which supports conceptus development through nutrient exchange, hormone production, and immune modulation. Alterations in placental development and function may therefore underlie the reduced efficiency of ET.

Background: Rhabdomyosarcoma (RMS) typically responds well to a combination of treatments with favorable prognosis in children 1 to 9 years old. However, infants may fare worse due to receiving less aggressive local therapy for concerns about long-term effects of surgery/radiation. This study investigates the clinical characteristics, treatment approach, and survival outcomes of RMS in children under 2.

In recent years, the hydrazide skeleton, as a pivotal class of nitrogen-containing structures, has garnered considerable attention in medicinal chemistry and organic synthesis owing to its unique chemical versatility and broad-spectrum biological activities. In this study, a series of thiazole-containing benzoylhydrazine derivatives -, -, and - with structural divergence from conventional hydrazide-based molecular frameworks were designed, synthesized, and evaluated for their antifungal/antioomycete activities. The antifungal/antioomycete assay showed that some of the targeted compounds exhibited remarkable and broad-spectrum antifungal activities.

A novel electrochemical/Fe dual-catalyzed perfluoroalkylation-thiolization of alkenes under mild conditions has been developed. This protocol utilizes commercially available reagents, cheap electrodes, and simple equipment. Diverse polyfunctionalized perfluoroalkyl-substituted derivatives were successfully obtained in a direct and efficient way with a broad substrate scope and excellent functional group tolerance.
