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 ...

Effect of blood contamination of cerebrospinal fluid on amino acids, biogenic amines, pterins and vitamins

Fluids and Barriers of the CNS, 2019
Background Cerebrospinal fluid (CSF) metabolomic investigations are a powerful tool for studying neurometabolic diseases. We aimed to assess the effect of CSF contamination with blood on the concentrations of selected biomarkers. Methods CSF samples were

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 ...

Biological Role of Carbamoyl pyridoxal 5'-phosphate

, 1997
A new compound, carbamoyl-pyridoxal 5'-phosphate (C-PLP), was synthetized by condensation of pyridoxal 5'-phosphate (PLP) with KCNO. It may be obtained under certain physiological conditions of pH, temperature and concentration of reagents. Formation and

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 ...
