Acetate as substrate for l-malic acid production with Aspergillus oryzae DSM 1863

Biotechnology for Biofuels, 2021
Background Microbial malic acid production is currently not able to compete economically with well-established chemical processes using fossil resources. The utilization of inexpensive biomass-based substrates containing acetate could decrease production

PbPH5, an H+ P-ATPase on the tonoplast, is related to malic acid accumulation in pear fruit

Journal of Integrative Agriculture, 2022
Organic acid content is one of the most important factors influencing fruit flavors. The predominant organic acid in most pear cultivars is malic acid, but the mechanism controlling its accumulation remains unclear.

Clinical, Histopathological, and Molecular Characterization of Pediatric MN1::ZNF341‐Associated Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Glycodeoxycholic acid synergizes with L-malic acid to upregulate the malolactic enzyme pathway to alleviate self-toxicity in Lacticaseibacillus paracasei L9

Applied and Environmental Microbiology
The malolactic enzyme (MLE) pathway induced by L-malic acid plays an important role for Lacticaseibacillus paracasei L9 to enhance the glycodeoxycholic acid (GDCA) tolerance.

Infantile Central Nervous System Juvenile Xanthogranuloma With Somatic CSF1R Mutation Responsive to Imatinib Monotherapy

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Juvenile xanthogranuloma (JXG) of the central nervous system (CNS) is a rare non‐Langerhans cell histiocytosis. CSF1R mutations have been reported for peripheral JXG, but not in CNS JXG. A 3‐month‐old male presented with fever, lymphadenopathy, and macrocephaly with bulging fontanelles.

Malic Acid Supplementation on Rumen Fermentation, Nutrient Digestibility, Performance and Carcass Traits in Lambs: A Meta-Analysis and Meta-Regression Considering Dietary Moderators

Animals
This meta-analysis and meta-regression evaluated how malic acid supplementation modulates rumen fermentation and its consequences for growth performance, nutrient digestibility, and carcass traits in lambs. Effect sizes (ES) were estimated using a random-
