Comparing the sensitivity of pyridoxal-5-phosphate, homocysteine and neopterin in coronary heart disease

Pteridines, 2002
Blood serum pyridoxal-5-phosphate, homocysteine and neopterin concentrations have been examined in 30 healthy individuals and 87 patients with coronary heart disease, verified by coronary angiography.

Dystrophia Smolandiensis is characterized by a novel NQO1 variant and a distinct phenotype from COL17A1‐associated epithelial recurrent erosion dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods DNA samples and clinical data from structured interview records were obtained from the Swedish families in which ...

SLC25A38 is required for mitochondrial pyridoxal 5’-phosphate (PLP) accumulation

Nature Communications
Many essential proteins require pyridoxal 5’-phosphate, the active form of vitamin B6, as a cofactor for their activity. These include enzymes important for amino acid metabolism, one-carbon metabolism, polyamine synthesis, erythropoiesis, and ...

Histopathologic Characterization of Cutaneous Oxalosis Mimicking Calciphylaxis: Diagnostic Pitfalls and Polarized Light Evaluation

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Cutaneous oxalosis is an uncommon manifestation of primary hyperoxalosis, which can often resemble other cutaneous manifestations of end stage renal disease (ESRD), particularly calciphylaxis. We report the case of a 46 year old female with primary hyperoxaluria type one (PH1) believed to be well‐controlled on lumasiran, a small interfering ...

Crystal structure of L-aspartate aminotransferase from Schizosaccharomyces pombe.

PLoS ONE, 2019
L-aspartate aminotransferase is a pyridoxal 5'-phosphate-dependent transaminase that catalyzes reversible transfer of an α-amino group from aspartate to α-ketoglutarate or from glutamate to oxaloacetate.

Prurigo Pigmentosa – an increasingly diagnosed dermatological condition associated with ketogenic diet

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
SUMMARY Prurigo pigmentosa (PP) is a rare inflammatory dermatosis, clinically characterized by intensely pruritic, erythematous papules and papulovesicles, with reticular hyperpigmentation upon healing. We herein report four cases in adults of different ethnic backgrounds, in which the disease was associated with ketogenic metabolic states due to ...

Comparative Study of Laboratory Diets for Piophila casei: Beneficial Effects of Infant Formula Supplementation

Entomologia Experimentalis et Applicata, EarlyView.
The infant formula‐based diet (F), the whole powder milk diet (P), and dry‐cured ham (H) were evaluated for rearing Piophila casei. H accelerated development, promoted earlier reproduction, and achieved the highest demographic performance but showed practical limitations linked to substrate deterioration. F enhanced larval survival and adult longevity,

Frontiers in Vitamin Research: New Antibodies, New Data

The Scientific World Journal, 2011
Since 2004, the anatomical distribution of vitamins in the monkey brain, studied using immunohistochemical techniques and new tools (specific antisera that discriminate different vitamins reasonably well), has been an ongoing research field.

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

The FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and
