Relative age-related deficit in trunk muscle density was greater in women than men whereas the relative decrease in muscle mass with age was similar in both sexes. The greater muscle fat content and greater age-related fat accumulation among women may contribute to women suffering more functional disabilities than men. INTRODUCTION: A better understanding of the effect of aging on trunk musculature will have implications for physical function, disability, pain, and risk of injury in older adults...

The ruminal microbiota plays major roles in feed digestion. The composition and fermentation of the bacterial communities in three important ruminant species have been studied previously. Here, we extended this research to the effect of concentrate-to-forage ratios on ruminal bacterial communities in Tarim red deer (Cervus elaphus yarkandensis). Different concentrate-to-forage ratios [2:8, 3:7, 4:6 and 5:5] were fed to Tarim red deer for 20 days. Ruminal bacterial communities were elucidated by 16S ribosomal RNA gene sequencing on an Illumina HiSeq 2500 platform...

Our global population is aging at an accelerated pace. While the average life expectancy has seen dramatic increases, chronic disease and disability have also increased, with rural America tending to be older, sicker, and poorer. This article examines the implementation and outcomes associated with the community engagement method of the world café that was instrumental in developing a "culture of health" aimed to reduce diabetes-related inequalities for older adults in rural counties of Kentucky...

Fibrous dysplasia is a benign developmental disorder of bone in which fibrous connective tissue containing abnormal bone with irregular trabeculae replaces normal cancellous bone. It may affect 1 (monostotic) or multiple bones (polyostotic). Polyostotic disease is the less common of the 2, occurring in only 20 to 25% of fibrous dysplasia patients and tending to affect those who are younger than 10 years of age; patients having this form tend to experience bone enlargement beyond normal skeletal maturation, which can cause pain, progressive damage, and increased risk of pathological fracture...

The release of pulmonary surfactant by alveolar type II (ATII) cells is essential for lowering surface tension at the respiratory air-liquid interface, stabilizing the lungs against physical forces tending to alveolar collapse. Hydrophobic surfactant protein (SP)-B ensures the proper packing of newly synthesized surfactant particles, promotes the formation of the surface active film at the alveolar air-liquid interface and maintains its proper structure along the respiratory dynamics. We report that membrane-associated SP-B efficiently induces secretion of pulmonary surfactant by ATII cells, at the same level as potent secretagogues such as ATP...

Osteoid osteomas of the wrist are relatively rare and the diagnosis is challenging due to atypical clinical features. We describe a case of an osteoid osteoma of the scaphoid bone associated with calcific tendinitis of the adjacent flexor carpi radialis tendon and periarticular soft tissue calcifications in a 21-year-old man presenting with radial-sided wrist pain. The lesion was successfully treated with CT-guided RF ablation. To our knowledge, this is the first description of an osteoid osteoma of the wrist associated with calcific tendinitis and periarthritis...

This study was designed to examine the effect of increasing age and type 2 diabetes on the average responses and inter- and intraindividual variability of falls risk, reaction time, strength, and walking speed for healthy older adults and older persons with type 2 diabetes (T2DM). Seventy-five older individuals (controls) and 75 persons with T2DM aged between 50 and 79 years participated in the study. Assessments of falls risk, reaction time (RT), knee extension strength, and walking speed were conducted. The results revealed that advancing age for both control and T2DM groups was reflected by a progressive increase in falls risk, decreased leg strength and a decline (i...

Adaptive radiation is a common evolutionary phenomenon in oceanic islands. From one successful immigrant population, dispersal into different island environments and directional selection can rapidly yield a series of morphologically distinct species, each adapted to its own particular environment. Not all island immigrants, however, follow this evolutionary pathway. Others successfully arrive and establish viable populations, but they remain in the same ecological zone and only slowly diverge over millions of years...

Tendon rupture induces an inflammatory response characterized by release of pro-inflammatory cytokines and impaired tendon performance. This study sought to investigate the therapeutic effects of simvastatin-loaded porous microspheres (SIM/PMSs) on inflamed tenocytes in vitro and collagenase-induced Achilles tendinitis in vivo. The treatment of SIM/PMSs in lipopolysaccharide (LPS)-treated tenocytes reduced the mRNA expressions of pro-inflammatory cytokines (Matrix metalloproteinase-3 ( MMP-3 ), cyclooxygenase-2 ( COX-2 ), interleukin-6 ( IL-6 ), and tumor necrosis factor-α ( TNF-α ))...

Posterior tibial tendinopathy (PTT) can lead to acquired flatfoot in adults. Many patients develop PTT without any identifiable risk factors. Molecular changes in extracellular matrix (ECM) and matrix metalloproteinase (MMP) polymorphism may influence the risk of developing PTT. We aim to investigate the association between matrix metalloproteinase-1 (MMP-1) and (MMP-8) gene polymorphisms with changes in collagen I, III and V in PTT. A case-control study with 22 patients and 5 controls was performed. The MMP-1 (2G/2G) and MMP-8 (T/T) genotypes were determined by PCR-restriction fragment length polymorphism...

Objective: Several lower limb tendinopathy treatment modalities involve identification of pathological paratendinous or intratendinous neovascularisation to target proposed co-location of painful neoneuralisation. The ability to reliably locate and assess the degree of neovascularity is therefore clinically important. The Modified Ohberg Score (MOS) is frequently used to determine degree of neovascularity, but reliability has yet to be established among Sport and Exercise Medicine (SEM) consultants...

Inflammation can arise in response to a variety of stimuli, including infectious agents, tissue injury, autoimmune diseases, and obesity. Some of these responses are acute and resolve, while others become chronic and exert a sustained impact on the host, systemically, or locally. Obesity is now recognized as a chronic low-grade, systemic inflammatory state that predisposes to other chronic conditions including metabolic syndrome (MetS). Although obesity has received considerable attention regarding its pathophysiological link to chronic cardiovascular conditions and type 2 diabetes, the musculoskeletal (MSK) complications (i...

AIM: Significant variability exists in the literature, with no clear consensus to the optimal protocol after a regenerative procedure. Given this uncertainty, the authors systematically reviewed the literature cataloging the different variables that may influence outcomes. METHODS: Search was limited to randomized clinical trials and prospective cohort studies of regenerative procedures for the treatment of tendinopathy. Variables were predetermined, and included: cyrotherapy, pre- and post-procedure nonsteroidal anti-inflammatory drugs use, recommendations for alternative pain medications, immobilization and duration of rest...
