Background: Recent evidence suggests that adiponectin may play a role in bone metabolism. However, little is known about the effect of doing exercise in this relationship. The aim of this study was to determinate the relationship between the adiponectin levels and bone mineral density in 50-70 years old active and non-active men. Methods: This is an analytical study. Thirty active and thirty...
Abstract Background: Reduction of bone density is some risk factors of falling, injury, or even death in elderly people. The purpose of the present study is investigating the effect of 12 weeks resistance training in water on bone density of elderly women. Methods: Thus 24 old women were selected after medical screening and randomly divided into two groups experimental (12 people, age 65±...
Background: To determine the relationship between lipid profile and bone turnover in pre and postmenopausal women. Methods: In a cross-sectional study, 279 women referred to Bone Mineral Densitometry (BMD) center of endocrinology and Metabolism research center for premenopausal evaluation were assessed for serum osteoporotegerin, receptor activator of nuclear factor kB (NF-kB) ligand (RANKL) an...
OBJECTIVE To investigate the effects of two doses of vitamin D given over 1 year on bone density in ambulatory patients on long-term antiepileptic drug (AED) therapy. METHODS We conducted two parallel, randomized, controlled trials in 72 adults (18 to 54 years old) and 78 children and adolescents (10 to 18 years) on long-term AED therapy. They received either low-dose vitamin D 400 IU/day or ...
Purpose: A three-dimensional (3D) finite element analysis (FEA) was performed to evaluate the influence of bone quality, on the stress/strain in bone surrounding the implant. Materials and methods: Three-dimensional finite element models created to replicate completely osseointegrated endosseous titanium implants, were used for the purpose of stress analysis. Two study groups consisting of a re...
CONTEXT Due to maldigestion, pancreatic exocrine insufficiency (PEI) in chronic pancreatitis may lead to deficiencies in fat-soluble vitamins, including vitamin D. This may, in turn, can cause disturbances in bone metabolism and reduce bone mineral density. OBJECTIVE To conduct a prospective study of maldigestion, bone metabolism, and bone mineral density in a group of patients with chronic p...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
BACKGROUND AND OBJECTIVES Darker skin pigmentation and aging are known factors influencing the body's ability to synthesize adequate amounts of vitamin D (25OHD). The objective of this study is to determine the 25OHD insufficiency in elderly African American females of low socioeconomic status (SES) in a southern latitude during springtime sun exposure. METHODS Patients >or= 70 years old who ...
We investigated the effect of locally administered bisphosphonate on distraction osteogenesis in a rabbit model and evaluated its systemic effect. An osteotomy on the right tibia followed by distraction for four weeks was performed on 47 immature rabbits. They were divided into seven equal groups, with each group receiving a different treatment regime. Saline and three types of dosage of alendr...
Background and Objective: This study was carried out to investigate the relationship between the amount of physical activity and daily calcium intake with body mass index and the amount of bone density in post-menopausal female patients. Materials and Methods: This descriptive-cross sectional study was performed on 80 post-menopausal women with mean age of 58.13±7.59 years and BMI mean of 26.69...
