Wu-tou decoction (WTD) is a classic traditional Chinese medicine formula and has been extensively used for the treatment of rheumatoid arthritis (RA). Previous reports indicates that WTD possesses anti-inflammatory and antinociceptive activities, and inhibits the development of arthritic joints and disease severity of collagen-induced arthritis (CIA) or adjuvant-induced rats; however, its action on angiogenesis of RA has not been clarified. The present study aims to determine the anti-angiogenic activity of WTD in CIA rats and in various angiogenesis models...

Prunella vulgaris L., a well-known traditional Chinese herbal medicine, has anti-inflammatory and antioxidant activities. In the present study, the underlying molecular mechanisms of the protective effect of P. vulgaris extract (PVE) were investigated in UVB-irradiated normal human dermal fibroblasts (NHDFs). The mRNA expression of matrix metalloproteinases (MMPs), procollagen type I and cytokines such as interleukin-6 (IL-6) and tumor necrosis factor (TNF-α) was determined by RT-PCR. The expression of anti-photo aging-related signaling molecules in the NF-κB, MAPK/AP-1, and TGF/Smad pathways was assessed by Western blot...

The aim of this study was to assess the effect of a physical exercise program based on Mat Pilates (MP) with TheraBand® on the dynamic balance of a sample population diagnosed with Parkinson's disease (PD). After random selection, 26 participants were allocated to a MP group or a control group where they performed calisthenics exercises. Both interventions lasted 12 weeks and involved 2 weekly sessions of 60 minutes. Assessments took place at baseline, 12 weeks after the intervention started and 4 weeks after the intervention was completed using the body mass index (BMI), the Timed Up and Go (TUG) test with Wiva® sensors, the 30 Second Chair Stand test, and the Five Times Sit to Stand test...

The objective of this study was to determine falls risk profiles to derive a falls risk prediction score and establish a simple and practical clinical screening tool for Chinese community-dwelling elderly individuals. This was a prospective cohort study (n = 619) among adults aged 60 years and older. Falls were ascertained at a 1-year follow-up appointment. Sociodemographic information, medical history, and physical performance data were collected. The mean age was 67.4 years; 57.7% were women. Female sex (odds ratios [ORs] 1...

Advancing age is the biggest risk factor for development for the major life-threatening diseases in industrialized nations accounting for >90% of deaths. Alzheimer's dementia (AD) is among the most devastating. Currently approved therapies fail to slow progression of the disease, providing only modest improvements in memory. Recently reported work describes mechanistic studies of J147, a promising therapeutic molecule previously shown to rescue the severe cognitive deficits exhibited by aged, transgenic AD mice...

Several studies have demonstrated the differentiation of human adipose tissue-derived stem cells (hADSCs) to neuronal and glial phenotypes, but directing the fate of these cells toward dopaminergic neurons has not been frequently reported. The aim of the present study was to investigate dopaminergic specification of hADSCs in vitro. ADSCs were isolated from subcutaneous abdominal adipose tissue and were characterized. For dopaminergic differentiation, a cocktail of sonic hedgehog, fibroblast growth factor 8, basic fibroblast growth factor and brain-derived neurotrophic factor were used under a low serum condition...

Frailty is a medical syndrome associated with advancing age characterized by reduced functional reserve, strength, endurance, and susceptibility to infection associated with high morbidity, hospitalization, and death. Nonspecific interventions to improve the healthspan of affected patients include physical therapy, exercise, improved nutrition, etc. Among the hallmarks of aging, depletion of stem cells with resultant compromise of regeneration and repair of tissues informs a rational stem cell-based replacement strategy...

Oxidative stress (OS) can induce cell apoptosis and thus plays an important role in aging. Antioxidant foods protect tissues from OS and contribute to a healthier lifestyle. In this study, we described the used of medaka embryos (Oryzias latipes) to study the putative antioxidant capacity of dietary cocoa extract in vertebrates. A polyphenol-enriched cocoa extract regulated the expression of several genes implicated in OS, thereby protecting fish embryos from induced OS. The cocoa extract activated superoxide dismutase enzyme activity in embryos and adult fish tissues, suggesting a common mechanism for protection during embryonic development and adulthood...

Older adults undergo a progressive decline in cardiorespiratory fitness and functional capacity. This lower peak oxygen uptake (VO2peak) level is associated with increased risk of frailty, dependency, loss of autonomy, and mortality from all causes. Regular physical activity and particularly aerobic training (AT) has been shown to contribute to better and healthy ageing. We conducted a meta-analysis in order to measure the exact benefit of AT on VO2peak in seniors aged 70 years or over. A comprehensive, systematic database search for manuscripts was performed in Embase, Medline, PubMed Central, ScienceDirect, Scopus, and Web of Science using key words...

Mitochondrial structural and functional integrity is maintained through the coordination of several processes (e.g., biogenesis, dynamics, mitophagy), collectively referred to as mitochondrial quality control. Dysfunctional mitochondrial quality control and inflammation are hallmarks of aging and are involved in the pathogenesis of muscle wasting disorders, including sarcopenia and cachexia. One of the consequences of failing mitochondrial quality control is the release of mitochondria-derived damage-associated molecular patterns...

The role of autophagy varies with the type of acute brain injury. In general, autophagy mediates a clear neuroprotective effect in intoxication caused by various psychoactive agents, subarachnoid hemorrhage and spinal cord injury. In contrast, autophagic cell death has also been reported to actively contribute to neuronal loss in neonatal hypoxic ischemic encephalopathy. However, it still remains to be determined whether autophagy pays a cytoprotective or a cytotoxic role in stroke. Previous studies focused primarily on the role of neurons rather than the role of astrocytes in brain injury...

Baicalein is a flavonoid isolated from the roots of Scutellaria baicalensis Georgi. This study aimed to ascertain the effects and potential underlying mechanisms of baicalein in d-galactose (d-gal)-induced aging rat model by integration of behavior examination, biochemical detection, and (1)H nuclear magnetic resonance (NMR)-based metabolomic approach. Our findings suggest that baicalein significantly attenuated memory decline in d-gal-induced aging model, as manifested by increasing recognition index in novel object recognition test, shortening latency time, and increasing platform crossings in Morris water maze test...

Alzheimer's disease (AD) is a common form of dementia and amyloid-β peptide (Aβ) aggregation is considered to be one of its main causes. Paeoniflorin has been previously shown to attenuate cognitive damage inflicted by exogenous Aβ protein. Using transgenic <i>Caenorhabditis elegans</i> models expressing human Aβ1-42, we demonstrate here that paeoniflorin can delay progressive paralysis caused by endogenous Aβ expression and reduce the amount of toxic Aβ oligomers in vivo although it has no effect on Aβ aggregation <i>in vitro</i>...
