1. Adipose tissue-derived stromal/stem cells + cholecalciferol: a pilot study in recent-onset type 1 diabetes patients
ABSTRACT Objective: Adipose tissue-derived stromal/stem cells (ASCs) and vitamin D have immunomodulatory actions that could be useful for type 1 diabetes (T1D). We aimed in this study to investigate the safety and efficacy of ASCs + daily cholecalciferol (VIT D) for 6 months in patients with recent-onset T1D. Materials and methods: In this prospective, dua

3. Effects of calcium to non-phytate phosphorus ratio and different sources of vitamin D on growth performance and bone mineralization in broiler chickens
ABSTRACT - A 7 × 2 factorial experiment was designed to test the effects of calcium (Ca) to non-phytate phosphorus (NPP) ratio (1.14, 1.43, 1.71, 2.00, 2.29, 2.57, and 2.86) and different sources of vitamin D (1α-hydroxycholecalciferol (1α-OH-D3) and 25-hydroxycholecalciferol (25-OH-D3)) on growth performance and bone mineralization in 1- to 42-d-old broi

4. Effect of different vitamin D sources and calcium levels in the diet of layers in the second laying cycle
This study evaluated the effects of different sources of vitamin D and calcium levels on performance, egg quality and bone strength of hens in the second production cycle. A total of 384 Hy-Line W36 birds with 80 weeks of age were used, alloted into 3 x 4 factorial design (sources of vitamin D: cholecalciferol; 25(OH)D3 and 1.25(OH)2D3 x calcium levels: 2.85

5. In ovo supplementation of 25(OH)D3 to broiler embryos
A dose of 0.3 mL of water solution containing 0.00 (control), 0.625, 1.250 or 1.875 µg of 25-hydroxy cholecalciferol (25(OH)D3) was administered to 312 fertile eggs derived from 49-w-old Cobb 500 broiler breeders on the 17th day of incubation (DE17) via allantoic cavity. After treatment, eggs were distributed and maintained until hatching in four incubators

6. Simultaneous and accurate determination of water- and fat-soluble vitamins in multivitamin tablets by using an RP-HPLC method
In the present study, a reversed-phase high-performance liquid chromatographic (RP-HPLC) procedure was developed and validated for the simultaneous determination of seven water-soluble vitamins (thiamine, riboflavin, niacin, cyanocobalamin, ascorbic acid, folic acid, and p-aminobenzoic acid) and four fat-soluble vitamins (retinol acetate, cholecalciferol, α

7. Suplementação com cholecalciferol em pacientes com doença renal crônica e hipovitaminose D / Cholecalciferol supplementation in chronic kidney disease patients with vitamin D insufficiency: a 6-month follow-up
Considerando a elevada prevalência de hipovitaminose D em pacientes na fase não dialítica da doença renal crônica (DRC) e os efeitos benéficos da restauração do estado nutricional de vitamina D nos pacientes com DRC nos parâmetros do metabolismo mineral, os guias de práticas clínicas para prevenção e tratamento dos distúrbios do metabolismo min

8. Effects of different dietary vitamin combinations on the egg quality and vitamin deposition in the whole egg of laying hens
The experiment was conducted to evaluate the effects of different dietary vitamin combinations on the egg quality and vitamin concentrations in the eggs of commercial laying hens. A total of 1,800 25-week-old Lohman pink-shell hens were randomly assigned to four dietary vitamin treatments as follows: NRC(1994) level, NRC (1994) level with Hy.D® (25-hydroxy-

9. VITAMINA D3 (COLECALCIFEROL) E 25-HIDROXI-COLECALCIFEROL (25-OHD3) EM RAÃÃES DE FRANGOS DE CORTE / Vitamin D3 (cholecalciferol) and 25-hidroxi-cholecalciferol (25-OHD3) in broiler chickens.
O experimento foi conduzido objetivando-se avaliar nÃveis/programas de vitamina D, proveniente das vitaminas D3 e 25-OHD3, em raÃÃes de frangos de corte criados em gaiolas. Utilizaram-se 1.500 pintos de um dia, machos, da linhagem Cobb-700, provenientes de incubatÃrio comercial, alojados em gaiolas metÃlicas (100), com dispositivos e manejo adaptados pa

10. Body fat and cholecalciferol supplementation in elderly homebound individuals
Vitamin D deficiency, observed mainly in the geriatric population, is responsible for loss of bone mass and increased risk of bone fractures. Currently, recommended doses of cholecalciferol are advised, but since there are few studies evaluating the factors that influence the serum levels of 25-hydroxyvitamin D (25(OH)D) following supplementation, we analyze

11. Dihydrotachysterol: a calcium active steroid not dependent upon kidney metabolism
The activity of dihydrotachysterol and cholecalciferol was determined in nephrectomized or sham-operated vitamin D-depleted rats using in vitro transport of calcium and phosphate by everted intestinal preparations as the index of physiologic response. The activity of dihydrotachysterol was not reduced by absence of the kidneys whereas that of cholecalciferol
