Relatively little is known about the bone health of ethnic groups within the UK and data are largely restricted to women. The aim of this study was to investigate ethnic differences in areal bone mineral density (aBMD), volumetric bone mineral density (vBMD), bone geometry and strength in UK men. White European, Black Afro-Caribbean and South Asian men aged over 40years were recruited from Grea...

an in vitro study on the role of intracellular calcium ions in healing of excisional wound in rabbit was undertaken. we employed two drugs namely, glibenclamide and nitroglycerin that are topically applied in vivo to modulate the activity of intracellular calcium. our model consisted of a 15 ´ 15 mm excisional wound. seven groups of new zealand rabbits were used. the first three groups served a...

background: appropriate endurance exercise can change bone mass density and strength of weight-bearing bones in both animals and humans, but its effects on the microstructure are not known. this study aimed to determine skeletal changes induced by the treadmill running endurance in ovariectomized adult mice. methods: twenty-seven adult female rats were divided into experimental and control grou...

in this research, the effect of temperature on the physical and chemical behavior of nylon 66 tire cords in the range of 50-200°c and 16 h testing was studied. the results showed that heat treatment considerably reduced the breaking strength of cords. the intensity of reduction of breaking strength below 100°c and above 120°c was more pronounced than intermediate temperatures. the changes in pr...

The present study evaluated the effects of a calcium (Ca) supplement derived from Gallus gallus domesticus (GD) on breaking force, microarchitecture, osteogenic differentiation and osteoclast differentiation factor expression in vivo in Ca-deficient ovariectomized (OVX) rats. One percent of Ca supplement significantly improved Ca content and bone strength of the tibia. In micro-computed tomogra...

The risk of sustaining tibia fractures as a result of a frontal crash is commonly assessed by applying measurements taken from anthropometric test devices to the Tibia Index. The Tibia Index is an injury tolerance criterion for combined bending and axial loading experienced at the midshaft of the leg. However, the failure properties of human tibia compact bone have only been determined under st...

The effects of 3 different furnished cage systems (Aviplus, Eurovent 625a, Eurovent 625A) on 2 different laying hen strains [Lohmann Selected Leghorn (LSL), Lohmann Brown (LB)] were examined for the traits of production, egg quality, bone strength, claw length, and keel bone status. Two trials were carried out in which all hens received identical feeding and management. In brown hens, the trait...

Background: Nutrient restriction is a common strategy to prevent metabolic disorders in fast growing broiler chickens, but limited information available regarding the impact of diets with low protein and energy on leg abnormalities. Objective: Two experiments were conducted evaluate effect varying crude (CP) metabolizable (ME) levels gastrocnemius tendon (GTeBS) tibia breaking strength (TiBS), ...

Abstract The first few weeks after broilers hatch are the period of most intense bone growth and development, time when they susceptible to influence various external internal factors. Research in recent decades has focused on involvement melatonin development during early life chickens. Melatonin release from pineal gland a circadian rhythm, with highest levels circulating night decreasing lig...
