Histomorphometry of bone.
This review of the histomorphometry of bone outlines methods of biopsy and processing of specimens in the laboratory, the basic principles of morphometry, and the measurements made in order to obtain estimates of the proportional volumes and surfaces occupied by different components of bone. Variability such as that between methods, observers and laboratories is discussed and a brief outline of...
متن کاملIssues in modern bone histomorphometry.
This review reports on proceedings of a bone histomorphometry session conducted at the Fortieth International IBMS Sun Valley Skeletal Tissue Biology Workshop held on August 1, 2010. The session was prompted by recent technical problems encountered in conducting histomorphometry on bone biopsies from humans and animals treated with anti-remodeling agents such as bisphosphonates and RANKL antibo...
متن کاملEvaluation of seasonal variation in acne vulgaris
Background and Aim: Acne vulgaris is one of the most common skin diseases in adolescents and young adults. Although acne do not physically disable the patient, it can cause significant psychological morbidities. The disease etiology is not fully understood; however, there are several factors involved in the pathogenesis. The aim of this study is to investigate the seasonal variation of acne vul...
متن کاملSeasonal variation in calcitropic hormones and bone accrual in puberty.
The production of 25-hydroxycholecalciferol (25(OH)D) in the liver is dependent on vitamin D obtained from the diet and from exposure to UV light. UV rays stimulate the conversion of provitamin D in the skin to vitamin D, making it available to the liver for hydroxylation to 25(OH)D. The circulating concentrations of 25(OH)D are considered to be reflective of the individual’s total vitamin D ex...
متن کاملSeasonal Variation in Ovine Compact Bone Time-dependent Material Properties
INTRODUCTION: The issue of whether, and to what extent, bone materials and fracture characteristics changes in humans with the seasons is complicated by matters of differential seasonal risk factors, nutritional opportunities, and social interaction. Studies examining seasonal bone turnover, density, and fracture risk have been hindered by wide intersubject variation and contradictory results. ...
