Modular Synthesis of α‐Quaternary Pyrrolines by Pyridoxal‐Catalyzed Sequential Reactions With Precise Chirality Relay

Transformative Chemistry, EarlyView.
Direct asymmetric α‐C conjugate addition of aminoacetonitrile enabled by carbonyl/iminium double activation, together with subsequent electrophilic functionalization, offers a one‐pot, two‐step modular strategy for synthesizing chiral α‐quaternary pyrrolines with precise chirality relay and high structural diversity.

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.

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 ...

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 ...

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 ...

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 ...

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.

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

Metabolism of [14C]- and [32P]Pyridoxal 5-Phosphate and [3H]pyridoxal Administered Intravenously to Pigs and Goats

, 1992
To gain more information about the kinetics of vitamin B-6 metabolism in vivo, the metabolism of tracer was examined after the simultaneous intravenous administration of [32P] and [14C]pyridoxal phosphate and [3H]pyridoxal in two 93-kg pigs and two 60-kg
