Abstract

fetched live from OpenAlex

Background and Aim: This study examines the effect of hypervitaminosis D on serum lipids and on kidney functions in New Zealand White (NZW) rabbit. It aims to study whether renal insufficiency or failure, due to hypervitaminosis D, is calcium-related or not. As well, it also discusses a possible link between hypervitaminosis D and hypercholesterolemia. Methods: Four Groups of six animals each, were divided into: Group I, received regular diet, Group II received regular diet +10,000/day vitamin D2; Group III, received 0.25% cholesterol diet; as well as Groups IV received 0.25% cholesterol diet plus 10,000 IU. Blood samples were taken at the end of the study and examined for Total Cholesterol (TC), Triglycerides (TG), Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), Blood Urea Nitrogen (BUN), Creatinine, Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), Calcium and Phosphate. As well, 25- hydroxyvitamin D (25 (OH) D) was measured using tandem LC-MS/MS. Results: The initial (0 time) serum TC, TG, LDL, HDL, Creatinine, Calcium, Phosphate and 25 (OH) D levels were not significantly different among different groups including control. At 1- and 2-month time, values from serum TC, TG, LDL, HDL and TC/HDL-C ration of Groups III and IV were significantly different from controls (p<0.05). As well, values from serum 25 (OH) D of Group II and IV were significantly different from controls (p<0.05) at 1- and 2-month time. However, values from serum Creatinine and Calcium of Group II were significantly different from controls (p<0.05) at 1- and 2-month time. Conclusion: Hypervitaminosis D may aggravate hypercholesterolemia, and it also induces renal insufficiency and/ or failure through a calcium-dependent mechanism. -- Highlights: 1. Excessive vitamin D supplementation, particularly when combined with a hypercholesterolemic diet, aggravated hyperlipidemia and elevated serum calcium levels in NZW rabbits. 2. Hypervitaminosis D was associated with increased serum creatinine and hypercalcemia, suggesting potential renal impairment secondary to excessive vitamin D intake

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
