background: the aim was to investigate the relationships among lean mass (lm), fat mass (fm), and bone mineral density (bmd) in women stratified by body mass index (bmi) (bmi – normal-weight, overweight, obese) and to determine threshold at which body fat assumes negative relationship with bmd. methods: this was a cross-sectional study in 471 healthy caucasian women, aged 18-67 years. bmd, lm, ...

background: tea consumption is common in our country and consumes more than coffee and other drinks. many studies investigated the association between coffee and bone mass density (bmd) but there is few study about association between tea and bmd. according to high prevalence of osteoporosis in country and change in demographic patterns that is associated with increasing middle-aged and older a...

rearing methods for bracon hebetor (say) (hym., braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. in these experiments, the effects of parasitoid and host densities on fertility and sex ratio of b. hebetor were assessed. in parasitoid de...

forty growing ram lambs (lori-bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in iran. the feed intake (fi), body weight (bw), gain to feed ratio (g:f) and carcass characteristics were studied. four treatments differed in metabolizable energy content (me) as follow; 2, 2.3, 2.6 and 2.9 mcal/kg for...

abstract   background: irregular working hours, including night work and shift work, have been found to be associated with alteration in various levels of biochemical factors. and some studies have showed association between shift work and blood biochemical disturbances in blood. in this epidemiological study we investigated, whether regular schedule of working hours can minimize the associated...

background: elevated serum levels of oxidized low-density lipoprotein (oxldl) have been found in type 2 and in poorly controlled diabetic patients. gestational diabetes mellitus (gdm) has common features with type 2 diabetes. objective: the aim of our study was to evaluate the serum levels of oxldl in women with gdm compared to normal pregnant women. materials and methods: in this cross-section...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

conclusions the findings indicated that older women with low bmi were at higher risk of low bone mass. body weight, bmi and aging may be important predictors of bmd, but they are not the only factors affecting bone loss. therefore, it is recommended to assess other risk factors with a larger number of patients. results the mean bmd of women older than 50 years compared to those younger than 50 ...
