Article Abstract

We synthesized novel vitamin K derivatives by converting the naphthoquinone group to benzene derivatives and benzoquinone. We evaluated their neuronal differentiation activities to investigate the effect of the quinone moiety on this process. We observed that the 1,4-quinone as well as the side chain part play important roles in neuronal differentiation. We also performed QSAR analysis to predict the compounds which would have higher differentiation activity.

Immunostimulatory and Immunomodulatory Effects of Vitamin B12 Derivatives on Macrophages Through the Modulation of JNK Pathway.

Vitamin B12 is a vital water-soluble vitamin containing a central cobalt atom within its corrin ring structure. It exists in several derivatives, among which methylcobalamin (MeCbl) and adenosylcobalamin (AdCbl) are the biologically active forms that serve as cofactors in essential enzymatic reactions. Although the neurological and hematological consequences of vitamin B12 deficiency have been extensively studied, its role in immune regulation remains less well understood.

Vitamin D Binding Protein, a Ligand of Integrin beta 1, Motivates Both Tumor Cells and Schwann Cells to Promote Perineural Invasion in Pancreatic Ductal Adenocarcinoma.

Perineural invasion (PNI) is a common pathological characteristic of pancreatic ductal adenocarcinoma (PDAC), closely linked to postoperative recurrence, metastasis, and unfavorable prognosis. Nevertheless, the precise mechanisms that govern PNI in PDAC remain poorly elucidated. Here, group-specific component protein (GC) is identified as one of the most significantly upregulated genes related to PNI, primarily derived from malignant ductal cells compared to other cell types.

The Application of Assay- and Age-Specific Parathyroid Hormone (PTH) Reference Intervals Decreases the Diagnosis of Normocalcaemic Primary Hyperparathyroidism and Improves Diagnostic Concordance of PTH Assays.

Parathyroid hormone (PTH) assays are not standardized and therefore PTH results are interpreted using manufacturer-provided assay-specific reference intervals. Assay-specific PTH reference intervals, however, do not account for between-assay differences and lead to discordance in the diagnosis of normocalcaemic primary hyperparathyroidism (NCPHPT). PTH increases with age independent of vitamin D, renal function, phosphate and ionized calcium.

Background: Although broad-scale data might suggest low prevalence, millions of children in India still suffer from Vitamin A and Vitamin D deficiencies despite India's existing guidelines for Vitamin A deficiency. To address the issue, the Government of India has recommended fortification of oil and milk to improve Vitamin A and Vitamin D consumption. However, there is limited information on the health benefits and cost-effectiveness of fortifying oil and milk at scale.
