Article Abstract
Normand cull-cows received a diet enriched in n-3 polyunsaturated fatty acids (PUFA), known to enhance nutritional quality, but to decrease beef lipid stability. Half of the cows received a supplementation of vitamin E and plant extracts rich in polyphenols during the finishing period. Half of each feeding group was slaughtered under limited, the others under added stress conditions. Longissimus thoracis (LT) and Semitendinosus (ST) were evaluated after storage under air, or 70% O/30% CO or vacuum conditions. Irrespectively of diet, pre-slaughter stress i) increased post-mortem malondialdehyde (MDA) formation except in vacuum-stored meat, ii) decreased vitamin A levels in the LT, iii) decreased vitamin E levels in meat stored in 70% O/30% CO and total anti-oxidant status in vacuum stored meat. Effects were global; dietary supplementation with vitamin E and plant extracts was associated with lower MDA levels and MetMb percentage and higher levels of vitamin A and E.
Rheumatoid arthritis (RA) is a chronic autoimmune disorder marked by joint inflammation and destruction. Recent studies emphasize the importance of vitamins D, B12, C, and K in managing RA and enhancing patient health. Vitamin D deficiency is common in RA patients and correlates with increased disease severity, indicating its potential to modulate immune responses and reduce inflammation.
Background And Aims: Seborrheic dermatitis (SD) is a chronic inflammatory skin condition that affects patients' quality of life. Emerging evidence suggests that vitamin and mineral deficiencies may contribute to its progression, although the exact etiology remains unclear.
Objective: This case-control study assessed the serum levels of vitamin D and zinc in SD patients compared to a healthy control group, with a focus on how these deficiencies relate to disease severity.
Background And Purpose: The timeline of alteration of vitamin D and calcium levels in those receiving anti-seizure medication (ASM) remains to be elucidated. To determine the changes in vitamin D levels over a period of 6 months among children receiving monotherapy with commonly used ASM.
Methods: The baseline serum levels of vitamin D, parathyroid hormone (PTH), calcium, alkaline phosphatase (ALP), phosphorus were measured in 32 children (median age 8 years) with newly diagnosed epilepsy.

Background: Type 2 diabetes mellitus (T2DM) is marked by insulin resistance, low grade chronic inflammation, and endothelial dysfunction. Vitamin K2, especially menaquinone-7 (MK-7), might delay T2DM progression and alleviate its consequences. Hence, this study evaluated the effects of MK-7 on serum and urine markers of diabetes in an animal model of T2DM.
Background: Autoimmune diseases pose significant health challenges worldwide and affect millions. In recent years, there has been growing interest in exploring preventive strategies through nutritional interventions using vitamins, antioxidants, and micronutrients to reduce the risk of developing autoimmune diseases. However, excessive supplementation has also been associated with toxicity.
