The aim of the study was to examine whether the TGF-beta1 T(861-20)-C gene polymorphism might be useful in identifying individuals with increased susceptibility to postmenopausal bone loss within the Turkish women population. T(861-20)-C polymorphism was genotyped in 616 postmenopausal women selected from the Turkish population: 311 postmenopausal osteoporotic women (OP) aged 45-65 years (mean age 58 years) and a control group (CG) of 305 postmenopausal women in the same age range (mean age 53 years) with normal bone mineral density. We have not found any significant differences in the frequency of the individual genotypes between the osteoporotic and control groups. The distribution of the T(861-20)-C genotypes was for Lumbar spine, CC, 74.0% in OP, 75.1% in CG; TC, 24.1% in OP, 23.9% in CG; TT, 1.9% in OP, 1.0% in CG; and for femoral neck, CC, 76.8% in OP, 72.8% in CG; TC, 22.1% in OP, 25.5% in CG; TT 1.1% in OP, 1.7% in CG. T(861-20)-C polymorphism was not found to be associated with bone mineral density in postmenopausal Turkish women. It was argued that this will be a pioneering study for the future research and therapies.

Social media-based Health Education plus Exercise Program (SHEEP) to improve muscle function among young-old adults with possible sarcopenia in the community: A feasibility study protocol.

Background: Despite the comparatively high prevalence of possible sarcopenia among young-old adults in the community, there is currently no available and effective social media-based intervention to increase the awareness and change the behavior of the target population to prevent sarcopenia. Using co-design methodology, we developed a multicomponent intervention strategy of health education and exercise for sarcopenia prevention utilizing the TikTok platform.
Objectives: The primary purpose of this study is to examine the feasibility and acceptability of the social media-based intervention to enhance muscle function in community-dwelling young-old adults with possible sarcopenia.
Overexpression of miR17 ~ 92 in Myeloid Cells in Mice Increased Bone Mass Through Reduced Bone Resorption and Increased Bone Formation in Sex-Dependent Manner.

This study assessed the feasibility of miR17 ~ 92-based antiresorptive strategy by determining the effects of conditional transgenic (cTG) overexpression of miR17 ~ 92 in myeloid cells on bone and osteoclasts. Osteoclasts of male and female cTG mutant mice each showed 3- to fivefold overexpression of miR17 ~ 92 cluster genes compared to those of age- and sex-matched wildtype (WT) littermates. Male but not female cTG mutant mice had more trabecular and cortical bones as well as lower bone resorption reflected by reduction in osteoclast number and resorbing surface.

Previous studies suggest social support is associated with musculoskeletal health in later life. We explored this relationship further in community-dwelling older adults, by considering associations between different aspects of social support and musculoskeletal health in community-dwelling adults. Participants from the Hertfordshire Cohort Study reported level of confiding/emotional, practical, and negative support using the Close Persons Questionnaire.

Rett syndrome (RS) is a rare neurodevelopmental disorder primarily caused by mutations in the X-linked methyl-CpG binding protein 2 (MECP2) gene, responsible for encoding MECP2 which plays a pivotal role in regulating gene expression. The neurological and non-neurological manifestations of RS vary widely in severity depending on the specific mutation type. Bone complications, mostly scoliosis but also osteoporosis, hip displacement, and a high rate of fractures, are among the most prevalent non-neurological comorbidities observed in girls with RS.

Human dentin performs its function throughout life, even though it is not remodeled like bone. Therefore, dentin must have extreme durability against daily repetitive loading. Elucidating its durability requires a comprehensive understanding of its shape, structure, and anisotropy at various levels of its structure.
