Stability-indicating HPLC-PDA assay for simultaneous determination of paracetamol, thiamine and pyridoxal phosphate in tablet formulations

Acta Pharmaceutica, 2019
With the increased number of multi-drug formulations, there is a need to develop new methods for simultaneous determinations of drugs. A precise, accurate and reliable liquid chromatographic method was developed for simultaneous determination of ...

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Role of Ascorbic Acid and Pyridoxal-5-Phosphate in the Prevention of Glucose-Induced Damage of Protein and DNA

Natural Product Communications
Objective: This study aims to assess the interaction of ascorbic acid (AA) and pyridoxal-5-phosphate (PLP) with serum protein for binding affinity. These vitamins are investigated for the glucose-induced glycation products for 28 days at 37 °C.

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Vitamin B6: too much, too little, too late? An analysis of sales trends in Australia from 2023 to 2025

Internal Medicine Journal, EarlyView.
Abstract Background Peripheral neuropathy associated with vitamin B6 (pyridoxine) is dose and duration dependent. High‐dose vitamin B6 products associated with adverse neurological effects are available in Australia, prompting recent regulatory action to reschedule products containing ≥50 mg pyridoxine to schedule 3 (pharmacist only).

Natural variation in the promoter of OsPDX1.2 enhances vitamin B6 accumulation and cold tolerance in rice

Journal of Integrative Plant Biology, EarlyView.
Allelic variation in the promoter of the pyridoxal phosphate synthase OsPDX1.2 caused variation in the ACE‐box cis‐elements, resulting in differing OsPDX1.2 expression due to differences in binding affinity between the OsbZIP18 transcriptipn factor and the ACE‐box, contributing to variation in vitamin B6 levels and cold tolerance among rice varieties ...

Engineering endosperm storage compartments enables simultaneous enrichment of multiple vitamins in rice

Journal of Integrative Plant Biology, EarlyView.
Engineering rice endosperm with modules for vitamin binding, lipid storage, and antioxidant protection enriched water‐ and fat‐soluble vitamins without compromising key agronomic traits and maintained vitamin higher levels after cooking, demonstrating its potential to improve crop nutrition.

Association of Vitamin B6 and Homocysteine–ACTH Coupling With Depressive and Anxiety Symptoms in Burning Mouth Syndrome: An Exploratory Case–Control Study

Journal of Oral Rehabilitation, EarlyView.
In this exploratory case–control study, plasma PLP (vitamin B6), homocysteine and ACTH concentrations did not differ between patients with burning mouth syndrome (BMS) and controls, and none discriminated patients individually. Within patients, however, psychological distress mapped onto a homocysteine–ACTH relationship from which PLP appeared ...

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...
