Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

open access: yesAdvanced Science, EarlyView.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...

Persistent Lactate Elevation in a Patient with Asthma Exacerbation and a Congenital Portosystemic Shunt: A Case Report and Literature Review

open access: yesReports
Background and Clinical Significance: When lactate production surpasses the body’s clearance capacity, hyperlactatemia (lactate ≥ 2 mmol/L) or lactic acidosis (lactate ≥ 4 mmol/L) can develop.

Significant Lactic Acidosis from Albuterol

open access: yesClinical Practice and Cases in Emergency Medicine, 2018
Lactic acidosis is a clinical entity that demands rapid assessment and treatment to prevent significant morbidity and mortality. With increased lactate use across many clinical scenarios, lactate values themselves cannot be interpreted apart from their ...

Severe hepatopathy and neurological deterioration after start of valproate treatment in a 6-year-old child with mitochondrial tryptophanyl-tRNA synthetase deficiency [PDF]

open access: yes, 2018
Background: The first subjects with deficiency of mitochondrial tryptophanyl-tRNA synthetase (WARS2) were reported in 2017. Their clinical characteristics can be subdivided into three phenotypes (neonatal phenotype, severe infantile onset phenotype ...

m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

The synergism of cytosolic acidosis and reduced NAD+/NADH ratio is responsible for lactic acidosis-induced vascular smooth muscle cell impairment in sepsis

open access: yesJournal of Biomedical Science
Background During sepsis, serve vascular dysfunctions lead to life-threatening multiple organ failure, due to vascular smooth muscle cells (VSMC) impairments, resulting in vasoplegia, hypotension and hypoperfusion.

Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults. [PDF]

open access: yes, 2019
Thiamine (vitamin B1) is an essential nutrient that serves as a cofactor for a number of enzymes, mostly with mitochondrial localization. Some thiamine-dependent enzymes are involved in energy metabolism and biosynthesis of nucleic acids whereas others ...

Expanding the Phenotype of TUFM‐Related Combined Oxidative Phosphorylation Deficiency 4

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Combined oxidative phosphorylation deficiency 4 (COXPD4) is a rare mitochondrial condition caused by biallelic deleterious variants in the nuclear‐encoded gene TUFM. To date, most individuals with COXPD4 have presented with encephalopathy, hypotonia, and abnormal brain imaging. Many of the reported individuals died in infancy. We aim to expand

In-vitro activation of complement system by lactic acidosis in newborn and adults

open access: yesMediators of Inflammation, 2001
Introduction: Complement activation occurs secondary to a variety of external stimuli. Lactic acidosis has been previously shown to activate the complement factors C3a and C5a.
