Background: Aim was to demonstrate the influencing factors of infant bone mineral density (BMD) and its correlation with serum 25-hydroxyvitamin D (25-(OH)D) in nursing mothers.
Methods: 200 children aged 0 č 1 years were rolled into normal group (n=120) and abnormal group (n=80) regarding the results of ultrasound BMD examination. The sunshine duration of infants with different BMD and 25(OH)D, calcium and phosphorus levels of nursing mothers were analyzed, and univariate and multivariate analyses of BMD were implemented.

Objective: Bone mineral density changes during the life span, rising rapidly during adolescence, plateauing around 30 years of age and decreasing in later years. Life events such as pregnancy and lactation temporarily reduce bone density, and their long-term effects on osteoporosis development are still unclear. This study aimed to analyse the association between pregnancy in adolescence and osteoporosis in aged women.

Our aim was to determine the effects of P intake on P balance, serum parathyroid hormone (PTH) levels and bone resorption during the final 4 weeks prepartum and the first 8 weeks of lactation. Sixty pregnant multiparous Holstein Friesian dairy cows were assigned to a randomized block design with repeated measurements and dietary treatments arranged according to a 2 × 2 factorial design. The experimental diets contained 3.

Unlabelled: We investigated the efficacy of romosozumab in premenopausal women with low bone mass. Romosozumab substantially increased bone mineral density and trabecular bone score in these women, aligning with its proven therapeutic benefits for postmenopausal osteoporosis.
Purpose: Romosozumab, an anti-sclerostin antibody, is a promising anabolic agent that increases bone formation and decreases bone resorption.

The use of exogenous phytase and vitamin D metabolites such as 25-hydroxycholecalciferol (25-OH-D) for poultry is well consolidated, but the potential for additive effects when supplementing both requires further investigation. This study investigated possible interactions between supplementation of 25-OH-D and high doses of phytase for broilers fed Ca- and P-deficient diets. A total of 1 200 one-d-old male broiler chicks were randomly allocated from one of four dietary treatments in a 2 × 2 factorial arrangement: 600 or 2 000 phytase units (FYT)/kg and with or without the inclusion of 25-OH-D at 69 µg/kg, with 12 replicates of 25 broilers each.
