FBXL4-related encephalomyopathic mitochondrial DNA depletion syndrome: A rare cause of hyperammonemia

open access: yesMolecular Genetics and Metabolism Reports
Introduction: FBXL4- related encephalomyopathic mitochondrial DNA (mtDNA) depletion syndrome is caused by pathogenic variants in the FBXL4 gene, resulting in mitochondrial dysfunction and multisystem involvement.

Epilepsy‐Related Psychosis in Drug‐Resistant Epilepsy With Nonconvulsive Status Epilepticus and Difficult Antipsychotic Titration: A Case Report

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 3, September 2026.
Electroclinical findings supported diazepam‐responsive nonconvulsive status epilepticus (NCSE) in an older patient with drug‐resistant epilepsy and psychosis. After phenytoin treatment, continuous EEG helped monitor recurrence. Later symptoms were most consistent with interictal psychosis with a possible alternative psychosis component, emphasizing ...

Idiopathic hyperammonemia after chemotherapy with vinorelbine, topotecan, and cisplatin in a patient with acute lymphocytic leukemia

open access: yesHematology/Oncology and Stem Cell Therapy, 2010
Idiopathic hyperammonemia (IHA) had been reported in some patients with hematological malignancy after receiving intensive chemotherapy, following bone marrow transplantation, or after using 5-fluorouuracil for some solid tumors.

Salt Treatment Confers Protection Against Acute Carp Edema Virus Reinfection While Promoting Viral Persistence

open access: yesJournal of Fish Diseases, Volume 49, Issue 9, September 2026.
ABSTRACT Carp edema virus (CEV) infects the common carp (Cyprinus carpio) and causes the lethal koi sleepy disease (KSD). Signs of KSD include respiratory, detoxification, and osmoregulatory difficulties. Salt treatment re‐equilibrates blood sodium levels and can save the fish. However, it is unclear whether these fish are immunized, remain chronically

Real‐world‐data for phenotypes and genotypes of rare monogenic genetic epilepsies and genes of uncertain significance for epilepsy

open access: yesEpilepsia Open, Volume 11, Issue 4, Page 1184-1199, August 2026.
Abstract Objectives The objectives of this study were to develop a real‐world‐data (RWD) database for patients with epilepsy to provide further real‐world‐evidence (RWE) for monogenic genetic epilepsies; to assess the usefulness of a diagnostic algorithm in epilepsy; and to examine protein 3D structures using in silico tools to predict variant ...

SIRT Family: Biological Functions and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 8, August 2026.
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These

Hyperornithinemia, Hyperammonemia, and Homocitrullinuria Syndrome Causing Severe Neonatal Hyperammonemia [PDF]

open access: yes, 2018
Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome (OMIM 238970) is an autosomal recessive disorder that is caused by a deficiency of mitochondrial ornithine transporter 1, resulting in dysfunction of the urea cycle. HHH is the rarest of the urea cycle disorders, reported in fewer than 100 patients.

Current Insight into Human Ornithine Aminotransferase: A Review

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1431-1441, August 2026.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.

Hyperammonemia impairs long-term potentiation in hippocampus by altering the modulation of cGMP-degrading phosphodiesterase by protein kinase G

open access: yesNeurobiology of Disease, 2004
Hyperammonemia impairs long-term potentiation (LTP) in hippocampus, by an unknown mechanism. LTP in hippocampal slices requires activation of the soluble guanylate cyclase (sGC)-protein kinase G (PKG)-cGMP-degrading phosphodiesterase pathway.
