Late-onset ornithine transcarbamylase deficiency caused by a somatic mosaic mutation

open access: yesHuman Genome Variation, 2018
An 18-month-old boy was diagnosed with late-onset ornithine transcarbamylase deficiency. Genetic analysis revealed a mosaic frameshift mutation (p.Q279fs) in the OTC gene.

Calcium, methyl jasmonate and their combined foliar applications: Influence on Tempranillo grape amino acids composition over two seasons

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7380-7396, September 2026.
Abstract BACKGROUND Climate change is currently affecting chemical grape composition and, consequently, grape quality. The foliar application of biostimulants has emerged as a promising approach to mitigate these effects. This study investigated the effects of foliar applications of calcium (Ca), methyl jasmonate (MeJ), and their combination (Ca + MeJ)

Ornithine transcarbamylase deficiency: neonatal diagnostic

open access: yesJornal de Pediatria, 1999
OBJECTIVE: To drive pediatrician's attention to a urea cycle enzyme deficiency. The prognosis is directly related to the early diagnosis and treatment. METHODS: We describe a newborn patient who present lethargy, vomitus and seizures 48 hours afther birth. We investigated this patient and the diagnosis of ornithine transcarbamylase deficiency was made.

Ammonia Metabolism in the Aging Liver: Emerging Mechanistic Insights

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Liver aging may weaken ammonia‐detoxification reserve by disrupting mitochondrial ureagenesis, GS‐mediated scavenging, glutamine metabolism, and metabolic zonation. This emerging framework links impaired nitrogen handling to potential hepatic stress amplification and systemic crosstalk, while highlighting the need for direct validation in physiological

Lactiplantibacillus plantarum AS21 Attenuates Sex‐Biased Glucose Intolerance in Aging Mice via Gut Mucosal Microbiota‐Derived Citrulline

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Aging induces sex‐differential glucose intolerance, with male‐specific citrulline depletion. Lactiplantibacillus plantarum AS21 elevates microbiota‐derived citrulline metabolism and enhances GLP‐1 secretion, improving glucose homeostasis. ABSTRACT Aging‐related metabolic decline, particularly impaired glucose tolerance, represents a growing challenge ...

Short‐Term Clinical Effects After Switching From Zinc Acetate Hydrate to Zinc Histidine Hydrate in Patients With Chronic Liver Disease

open access: yesHepatology Research, Volume 56, Issue 8, Page 1286-1291, August 2026.
Zinc deficiency is frequently seen in patients with chronic liver disease and is linked to poor appetite and nutritional status. We found that switching to zinc histidine hydrate increased zinc levels within a short period and was associated with improved appetite.
