There is growing evidence that severe decline of skeletal muscle mass and function with age may be mitigated by exercise and dietary supplementation with protein and amino acid ingredient technologies. The purposes of this study were to examine the effects of the leucine catabolite, beta-hydroxy-beta-methylbutyrate (HMB), in C2C12 myoblasts and myotubes, and to investigate the effects of dietar...
β-Hydroxy-β-methylbutyrate (HMB) is a popular ergogenic aid used by human athletes and as a supplement to sport horses, because of its ability to aid muscle recovery, improve performance and body composition. Recent findings suggest that HMB may stimulate satellite cells and affect expressions of genes regulating skeletal muscle cell growth. Despite the scientific data showing benefits of HMB s...
Early posthatch satellite cell mitotic activity is an important aspect of muscle development. An understanding of the interplay between nutrition and satellite cell mitotic activity will lead to more efficient meat production. The objective of this study was to test the influence of the leucine metabolite, beta-hydroxy beta-methylbutyrate (HMB), and feed deprivation on muscle development in the...
A unique case of a metastatic non-desmoplastic sarcomatoid malignant melanoma in an axillary lymph node showing smooth muscle differentiation in a 54 year old woman is described. The tumour cells exhibited alpha-smooth muscle actin, HHF-35 and desmin positivity but were negative for S100 protein and HMB-45. Ultrastructural examination revealed smooth muscle phenotype and there was no evidence o...
We report a case of angiomatoid melanoma on the right thigh of a 59-year-old man. The histologic growth pattern of the tumor mimicked vascular proliferation, and the cells lining the pseudovascular spaces were positive for protein S-100, HMB-45, and MITF-1. The differential diagnosis is with angiosarcoma and pseudovascular adenoid squamous cell carcinoma. The case we present is the fifth report...
Acrosyringium, duct and secretory epithelium as well as myoepithelial cells of human eccrine sweat glands have been characterized by different immunostaining patterns with mono- and polyclonal antibodies to a wide spectrum of tissue antigens. Using monoclonal antibodies to neuron-specific enolase (NSE) and melanoma-associated antigens (LS 59, HMB-45, NKI/C-3) the expression of neuroectodermal a...
The maintenance of muscle mass and muscle strength is important for reducing the risk of chronic diseases. The age- related loss of muscle mass and strength is associated with adverse outcomes of physical disability, frailty and death. β-Hydroxy β-Methyl Butyrate (HMB), a metabolite of leucine, has beneficial effects on muscle mass and strength under various catabolic conditions. The objectives...
β-Hydroxy-β-methylbutyrate (HMB) is a leucine metabolite shown to reduce protein catabolism in disease states and promote skeletal muscle hypertrophy in response to loading exercise. In this study, we evaluated the efficacy of HMB to reduce muscle wasting and promote muscle recovery following disuse in aged animals. Fisher 344×Brown Norway rats, 34 mo of age, were randomly assigned to receive e...
هدف از این پژوهش، بررسی تأثیر مصرف کوتاه مدت مکمل hmb (بتا-هیدروکسی-بتا متیل بوتیرات) بر تغییرات سطح کراتین فسفو کیناز بعد از پروتکل تمرینی منتخب در زنان غیر ورزشکار بود. بدین منظور 16 زن غیر ورزشکار با میانگین سن 3/24 سال ، قد 163 سانتی متر و وزن 5/61 کیلو گرم انتخاب و به طور تصادفی به دو گروه مصرف hmb (8=n) و گروه دارونما (8=n) تقسیم شدند. یک پیش آزمون و سه پس آزمون جهت اندازه گیری شاخص آسیب ...
A prospective clinical study was carried out to investigate whether endometrial microvessels in patients with idiopathic heavy menstrual bleeding (HMB) of endometrial origin (HMB-E) are fragile due to low pericyte coverage. Idiopathic HMB-E is characterized by large endothelial cell gaps related to the microvascular overexpression of vascular endothelial growth factor (VEGF)-A and VEGF receptor...
