Department of Ophthalmology, The Affiliated Hospital of Hangzhou Normal University, Hangzhou, China.
Aim: This study aimed to explore the association between the ratio of 4-pyridoxine (4-PA) to pyridoxal 5'-phosphate (PLP) (4-PA/PLP) and diabetic retinopathy (DR) and further assess the mediating effect of Endothelial Activation and Stress Index (EASIX) on the association between 4-PA/PLP and DR.
Methods: In this cross-sectional study, 1,698 patients with diabetes from the National Health and Nutrition Examination Survey were included. According to the median, 4-PA/PLP was categorized into a high-level group (≥0.
Personalized Medicine Through Semisolid-Extrusion Based 3D Printing: Dual-Drug Loaded Gummies for Enhanced Patient Compliance.
Pharm Res
January 2025
Department of Pharmaceutics and Drug Delivery, School of Pharmacy, The University of Mississippi, University, MS, 38677, USA.
Purpose: The purpose of this research was to develop and characterize dual-drug Isoniazid-Pyridoxine gummies using Semisolid Extrusion (SSE) 3D printing technology, aimed at personalized dosing for a broad patient demographic, from pediatric to geriatric. This study leverages SSE 3D printing, an innovative approach in personalized medicine, to enable precise dose customization and improve patient adherence. By formulating dual drug-loaded gummies, the research addresses the challenges of pill burden and poor palatability associated with traditional tuberculosis regimens, ultimately enhancing the therapeutic experience and effectiveness for patients across various age groups.

Combinations of cysteine, ascorbic acid, and pyridoxine are frequently used in oral formulations. Although there have been many reports on the efficacy of each of these ingredients, little information is known about their combined effects on skin cells. The purpose of this study was to evaluate the combined effects of cysteine, ascorbic acid, and pyridoxine, as well as the effect of adding α-lipoic acid, on skin cells.

Article Synopsis
- Malnutrition and low micronutrient levels are common in patients with ulcerative colitis (UC), and this study examined how different vitamin B groups might help improve the condition.
- Experimental colitis was induced in rats, and both high and normal doses of several B vitamins were administered; results showed significant improvements in weight and ulceration measures following treatment.
- While most vitamins showed beneficial anti-inflammatory effects, pyridoxine was less effective in reducing UC symptoms, indicating a need for further research on the clinical implications of these findings.
Substrate transport and drug interaction of human thiamine transporters SLC19A2/A3.

Thiamine and pyridoxine are essential B vitamins that serve as enzymatic cofactors in energy metabolism, protein and nucleic acid biosynthesis, and neurotransmitter production. In humans, thiamine transporters SLC19A2 and SLC19A3 primarily regulate cellular uptake of both vitamins. Genetic mutations in these transporters, which cause thiamine and pyridoxine deficiency, have been implicated in severe neurometabolic diseases.
