The prevalence of lower urinary tract (LUT) symptoms increases with age but the etiology is unknown. This article aims to identify research directions that clarify the basis of this association. The initial question is whether biological age is the variable of interest or a time-dependent accumulation of factors that impact on LUT function at rates that differ between individuals. In particular, the accumulation of conditions or agents due to inflammatory states or tissue ischemia is important. Much of the above has been concerned with changes to bladder function and morphology...

MG53 (also known as TRIM72) is a cardiac and skeletal muscle-specific TRIM-family protein that exhibits multiple biological functions. First, MG53 participates in plasma membrane repair of the heart, skeletal muscle and other tissues. Second, MG53 is essentially involved in the cardioprotection of cardiac ischemic, pre-conditioning and post-conditioning, by activating the PI3K-Akt-GSK3β and ERK1/2 survival signaling pathways. Moreover, systemic delivery of recombinant MG53 protein ameliorates the impact of a range of injury insults on heart, skeletal muscle, lung, kidney, skin and brain...

BACKGROUND: There has been remarkable growth in research examining physical activity behavior (any bodily movement produced by skeletal muscle contraction that results in energy expenditure) among people living with multiple sclerosis (MS) over the past decade. The current meta-analysis quantified physical activity participation levels in persons with MS compared with non-diseased and other clinical populations. METHODS: We searched PUBMED, PsycINFO and Web of Science using the keywords physical activity, exercise, and physical fitness in conjunction with MS...

Jinjin Ma, Andrew R Baker, Anthony Calabro, Kathleen A Derwin
Wounds causing extensive injury loss of muscle, also known as volumetric muscle loss (VML), are frequently associated with high-energy civilian trauma and combat-related extremity injuries. Currently, no effective clinical therapy is available for promoting de novo muscle tissue regeneration to restore muscle function following VML. Recent studies have shown evidence that osteoactivin (OA), a transmembrane glycoprotein, has the ability to prevent skeletal muscle atrophy in response to denervation. Therefore the objective of this study is to investigate the potential regenerative effect of OA embedded and delivered via a cross-linked gelatin hydrogel within a volumetric tibialis anterior muscle defect in a rat model...

PURPOSE OF REVIEW: This review summarizes what has been learned about the interaction between skeletal muscle and bone from mouse models in which BMAL1, a core molecular clock protein has been deleted. Additionally, we highlight several genes which change following loss of BMAL1. The protein products from these genes are secreted from muscle and have a known effect on bone homeostasis. RECENT FINDINGS: Circadian rhythms have been implicated in regulating systems homeostasis through a series of transcriptional-translational feedback loops termed the molecular clock...

Sarcopenia is an age-related syndrome characterised by progressive and generalised loss of skeletal muscle mass and strength; it is a major contributor to the risk of physical frailty, functional impairment in older people, poor health-related quality of life and premature death. Many different definitions have been used to describe sarcopenia and have resulted in varying estimates of prevalence of the condition. The most recent attempts of definitions have tried to integrate information on muscle mass, strength and physical function and provide a definition that is useful in both research and clinical settings...

Patients with low appendicular lean mass plus slow gait speed or weak grip strength are at risk for poor functional recovery after surgery for distal radius fracture, even when they have similar radiologic outcomes. INTRODUCTION: Loss of skeletal muscle mass and consequent loss in muscle function associate with aging, and this condition negatively impacts the activities of daily living and increases elderly individuals' frailty to falls. Thus, patients with low appendicular lean mass would show different functional recovery compared to those without this condition after surgery for distal radius fracture (DRF)...

Real-time reverse transcription-polymerase chain reaction (RT-PCR) analysis is a popular method for the measurement of mRNA expression level and is a critical tool for basic research. The identification of suitable reference genes that are stable and not affected by experimental conditions is a critical step in the accurate normalization of RT-PCR. On the other hand, the levels of numerous transcripts exhibit circadian oscillation in various peripheral tissues and it is thought to be regulated by feeding rhythms in addition to the molecular circadian clock...

Telomeres protect the integrity of information-carrying DNA by serving as caps on the terminal portions of chromosomes. Telomere length decreases with aging, and this contributes to cell senescence. Recent evidence supports that telomere length of leukocytes and skeletal muscle cells may be positively associated with healthy living and inversely correlated with the risk of several age-related diseases, including cancer, cardiovascular disease, obesity, diabetes, chronic pain, and stress. In observational studies, higher levels of physical activity or exercise are related to longer telomere lengths in various populations, and athletes tend to have longer telomere lengths than non-athletes...

Importance: Research shows that resveratrol, a sirtuin activator in red wine, improves exercise endurance and skeletal-muscle oxidative metabolism in animals and may enhance vascular function in humans. Resveratrol supplement sales exceed $30 million annually in the United States, but few data are available regarding its efficacy in humans. Objective: To determine whether resveratrol, 125 mg/d or 500 mg/d, improves the 6-minute walk performance in patients with peripheral artery disease (PAD)...

Ischaemic postconditioning (IPostC) was introduced for the first time by Zhao et al. as a feasible method for reduction of myocardial ischaemia-reperfusion (IR) injury. The cardioprotection by this protocol has been extensively evaluated in various species. Then, further research revealed that IPostC is a safe and convenient approach in limiting IR injury of non-myocardial tissues such as lung, liver, kidney, intestine, skeletal muscle, brain and spinal cord. IPostC has been conducted with different algorithms, resulting in diverse effects...

Obesity is an ongoing pandemic and serves as a causal factor of a wide spectrum of metabolic diseases including diabetes, fatty liver disease, and cardiovascular disease. Much evidence has demonstrated that nutrient overload initiates or exacerbates inflammatory responses in tissues/organs involved in the regulation of systemic metabolic homeostasis. This obesity-associated inflammation is usually at a low-grade and viewed as metabolic inflammation. When it exists continuously, inflammation inappropriately alters metabolic pathways and impairs insulin signaling cascades in peripheral tissues/organs such as adipose tissue, the liver and skeletal muscle, resulting in local fat deposition and insulin resistance and systemic metabolic dysregulation...

MicroRNAs (miRNAs) are a class of non-coding RNAs that play a crucial regulatory role in many biological processes. Previous studies have reported miRNAs that are associated with the growth, differentiation, and proliferation of myocytes and adipocytes in pigs. However, differences in the miRNA expression profiles between muscle and adipose tissues during porcine development are unknown. Muscle and adipose tissues are the two major organs that are crucial for dynamic energy balance in the development and metabolism...

PURPOSE OF REVIEW: To give an overview of recent research findings and insights on the role of body composition assessment in fracture risk prediction. RECENT FINDINGS: While there is to date little doubt that bone mineral density (BMD) is a main pathogenic factor of osteoporotic fractures, recent studies have emphasized the independent contribution of body composition components, especially lean mass, to fracture risk. In this article, we address body composition changes with aging, before to focus on recent studies addressing the contribution of lean and fat mass to fracture risk, together with some hypothesized mechanisms and clinical implications...

BACKGROUND & AIMS: Recent research suggests that variations of skeletal muscle (SM) and fat predict the severity of chemotherapy-induced toxicities in patients with renal cell carcinoma (RCC). Cardio-toxicity has not been evaluated in this context. METHODS: In this study we considered 47 RCC patients who participated in randomized clinical trials of sorafenib or sunitinib (i.e., targeted therapy). To capture cardio-toxicity, multi gated acquisition (MUGA) scan-defined left ventricular ejection fraction (LVEF) tests (at least 3 tests over 1 year of treatment) were abstracted...

The discovery of ClC proteins at the beginning of the 1990s was important for the development of the Cl(-) transport research field. ClCs form a large family of proteins that mediate voltage-dependent transport of Cl(-) ions across cell membranes. They are expressed in both plasma and intracellular membranes of cells from almost all living organisms. ClC proteins form transmembrane dimers, in which each monomer displays independent ion conductance. Eukaryotic members also possess a large cytoplasmic domain containing two CBS domains, which are involved in transport modulation...
