Pyridoxine-responsive PH1: Treatment

, 1998
Owing to the rarity of PH, the efficacy of pyridoxine therapy has only been tested in very small series of patients. From two recent reports including 18 patients, 50% of patients would be unresponsive to pyridoxine whereas oxaluria would be normalized ...

The Microbiome as a Mirror: Distinguishing Healthy Individuals From Chronic Constipated Patients and Identifying Those With Hidden Psychiatric Burden

Microbiota Medicine Research, EarlyView.
Gut microbiota signatures distinguish chronic constipated patients from healthy individuals, supporting noninvasive diagnostic potential. Despite challenges in identifying psychiatric‐related comorbidities, microbial alterations, particularly in neurotransmitter and inflammatory pathways, lay the groundwork for future companion diagnostics and ...

Washed Microbiota Transplantation Improves Chronic‐Phase Febrile Infection‐Related Epilepsy Syndrome: The First Case Report With Long‐Term Follow‐Up and Integrated Multi‐Omics Analysis

Microbiota Medicine Research, EarlyView.
ABSTRACT Background Febrile infection‐related epilepsy syndrome (FIRES) is a catastrophic epileptic encephalopathy. Survivors often enter a chronic phase characterized by drug‐resistant epilepsy, cognitive impairment, behavioral and psychiatric symptoms, and long‐term functional disability.

Impact of the GouM transporter on secondary metabolism activation and production yield in Streptomyces noursei strain CK‐15

New Plant Protection, EarlyView.
Overexpression of the gouM transporter gene in Streptomyces noursei CK‐15 enhances gougerotin production by 114% and activates silent biosynthetic gene clusters. This finding links transporter activity to metabolite efflux and secondary metabolism, offering a strategy for natural product discovery and strain optimization.

Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

Case report: Clinical and genetic characterization of a novel ALDH7A1 variant causing pyridoxine-dependent epilepsy, developmental delay, and intellectual disability in two siblings

Frontiers in Psychiatry
BackgroundPathogenic variants in ALDH7A1 are associated with pyridoxine-dependent epilepsy (PDE), a rare autosomal recessive disorder characterized by epileptic seizures, unresponsiveness to standard antiseizure medications (ASM), and a response only to ...

Spectroelectrochemical Investigation of the Interaction of Adenine with Pyridoxine at Physiological pH

Journal of Spectroscopy, 2019
Spectroelectrochemical techniques were used to probe the interaction of adenine with pyridoxine at pH 7.0. Analysis of UV-visible absorption of the adenine-pyridoxine complex at 260 nm using the Lineweaver–Burk double reciprocal plot produced a linear ...

Homocystinuria: Reduced folate levels during pyridoxine treatment

, 1973
Homocystinuria: reduced folate levels during pyridoxine treatment. Nine patients with homocystinuria due to cystathionine synthase deficiency were treated with pyridoxine: 6 responded biochemically and 5 of these showed marked clinical improvement.

A pH‐Responsive fluorescence lifetime probe reveals GOT1 phase separation in cellular anti‐senescence

Smart Molecules, EarlyView.
Acidic pH triggers GOT1 phase separation via IDR1, recruiting ME1 to form ROS‐scavenging condensates that combat senescence, revealed by a FLIM‐based pH probe. Abstract Cellular senescence involves progressive acidification, but how cells sense and adapt to this pH shift remains unclear.
