Effects of aging, gender, and hypogonadism on mandibular bone density.

Aim: The aim of the present study was to evaluate how aging, sex, and hypogonadism influence mandibular bone density with and without the benefits of hormone treatment.

Methods: Three-month old Wistar rats were randomly assigned to three experimental groups, with eights animals per group: controls, castrated (orchiectomized [ORX], ovariectomized [OVX]) and castrated with hormonal treatment (ORX + testosterone, OVX + estradiol benzoate). Females were previously evaluated by vaginal cytology.

Maternal Flaxseed Oil During Lactation Enhances Bone Development in Male Rat Pups.

Flaxseed oil is an alpha linolenic acid source important in the growth and body development stage; furthermore, this acid acts on adipose tissue and bone health. The aim of this study was to evaluate body composition, fatty acid composition, hormone profile, retroperitoneal adipocyte area and femur structure of pups at weaning, whose mothers were fed a diet containing flaxseed oil during lactation. After birth, pups were randomly assigned: control (C, n = 12) and flaxseed oil (FO, n = 12), rats whose mothers were treated with diet containing soybean or flaxseed oil.

Effects of diet containing flaxseed flour (Linum usitatissimum) on body adiposity and bone health in young male rats.

Flaxseed flour has been described as an excellent alpha-linolenic acid source. This study was designed to evaluate the effects of flaxseed flour on body adiposity and bone health in rats fed a flaxseed flour diet during lactation until 90 days. At birth, male Wistar rats were randomly assigned to control (C) and experimental (FF) groups, whose dams were treated with a control or flaxseed flour diet, respectively, during lactation.

Flaxseed flour (Linum usitatissinum) consumption improves bone quality and decreases the adipocyte area of lactating rats in the post-weaning period.

The aim of this work was to evaluate the effects of flaxseed flour in the intake on adiposity and femur structure of the lactating rats during the post-weaning period. After weaning, the lactating rats were divided into control (C, n = 6) and experimental (F, n = 6) groups treated with a diet containing flaxseed flour. Serum hormone and fatty acids composition, morphology of intra-abdominal adipocytes, computed tomography and biomechanical analyses of femur were determined.

Body adiposity and bone parameters of male rats from mothers fed diet containing flaxseed flour during lactation.

Obesity and osteoporosis may have their origins in early postnatal life. This study was designed to evaluate whether flaxseed flour use during lactation period bears effect on body adiposity and skeletal structure of male rat pups at weaning. At birth, male Wistar rats were randomly assigned to control and experimental (FF) groups, whose dams were treated with control or flaxseed flour diet, respectively, during lactation.
