Cyclin D3 is an important regulator for transition from G(1) to the S phase of the cell cycle. Cyclin D3 expression is associated with cell proliferation in lymphoid tissues, but its impact on clinical outcome in non-Hodgkin's lymphomas has not been studied. Therefore, we determined the clinical relevance of cyclin D3 expression in patients with diffuse large B-cell lymphoma. We examined the re...

Let T : [0, 1] → [0, 1] be the doubling map and let 0 < a < b < 1. We say that an integer n ≥ 3 is bad for (a, b) if all n-cycles for T intersect (a, b). Let B(a, b) denote the set of all n which are bad for (a, b). In this paper we completely describe the sets: D2 = {(a, b) : B(a, b) is finite} and D3 = {(a, b) : B(a, b) = ∅}. In particular, we show that if b − a < 1 6 , then (a, b) ∈ D2, and ...

BACKGROUND Vitamin D (D) supplements are indispensable for its world-wide deficiency. Controversy continues on ergocalciferol (D2) and cholecalciferol (D3) relative potency as well as on dosing-schedule and sex role in raising 25-hydroxy D (25(OH)D) level, the best indicator of D status. METHODS We randomized 279 adults to daily D2, D3, D2/D3, or placebo; 2-weekly D2 or D3; or 4-weekly D2 or ...

This study was conducted to evaluate the relative bioavailability (RBV) of 25-hydroxycholecalciferol (25-OH-D3) to cholecalciferol (vitamin D3) in 1- to 21-d-old broiler chickens fed with calcium (Ca)- and phosphorus (P)-deficient diets. On the day of hatch, 450 female Ross 308 broiler chickens were assigned to nine treatments, with five replicates of ten birds each. The basal diet contained 0....

Practical biomarkers of Alzheimer's disease (AD) prognosis are lacking. Correspondingly, no drugs are known to decrease disease progression, although vitamin D3 has positive effects on cognition in vivo and 1α, 25-dihydroxyvitamin D3 (1,25 D3) on amyloid-β 1-42 (Aβ) phagocytosis in vitro. We have examined in a pilot study a new biomarker in peripheral blood mononuclear cells, the transcription ...

Ultraviolet radiation is known to be highly variable in aquatic ecosystems. It has been suggested that UV-exposed organisms may demonstrate enough phenotypic plasticity to maintain the relative fitness of natural populations. Our long-term objective is to determine the potential photoprotective effect of vitamin D3 on Daphnia pulex exposed to acute or chronic UV radiation. Herein we report our ...

BACKGROUND Several studies suggest that Vitamin D (Vit-D3) supplementation reduces Chronic Urticaria (CU) symptoms. OBJECTIVES Evaluation of serum 25-hydroxyvitamin-D (25 (OH)2D) level and assessment of therapeutic effect of VitD3in CU patients. METHODS 192 subjects were stratified according to the baseline 25(OH)2D levels and subsequently randomized into three subgroups to receive Vit-D3 a...

Background and Objectives: Previous research has established that Vitamin D3 (Cholecalciferol) deficiency is considered to be a highly prevalent nutritional problem worldwide. Data from National Food and Nutrition Surveillance Program (2015) revealed that prevalence of vitamin D3 deficiency in Iran is more than 70% of the population. Vegetable oils are considered to be potential candidates for ...
