Dihydroorotate dehydrogenase (DHODH) regulates trophoblast syncytialization through organelle stress–induced cellular senescence

FEBS Open Bio, EarlyView.
The inhibition of mitochondrial dihydroorotate dehydrogenase (DHODH) impairs syncytialization and induces cellular senescence via mitochondrial and endoplasmic reticulum stress in human trophoblast stem cells, elevating sFlt1/PlGF levels, a hallmark of placental dysfunction in hypertensive disorders of pregnancy.

Changes in Immune‐Inflammation Status and Acute Ischemic Stroke Prognosis in Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Inflammation is a critical risk factor for poor outcomes in cerebral infarction. Prior studies focused primarily on baseline inflammation status, neglecting dynamic longitudinal changes. We try to investigate the association between immune‐inflammation status alterations and stroke prognosis, and evaluated three systemic biomarkers'

Time to anoxia: Observations and predictions of oxygen drawdown following coastal flood events

Geoderma
The coastal terrestrial-aquatic interface (TAI) is a highly dynamic system characterized by strong physical, chemical, and biological gradients. In particular, shifting soil redox conditions and consumption of terminal electron acceptors, due in part to ...

Rethinking Strategies for a Pharmaceutical Approach to Pain Related to Connective Tissue–Related Raynaud Phenomenon in the United States

Arthritis Care &Research, EarlyView.
Objective There are no US Food and Drug Administration–approved therapies for Raynaud phenomenon (RP) in the United States. Clinical trials have been challenged by study design. Important advances in RP patient‐reported outcome measures and mechanistic quantification allow RP‐related pain characterization.

Synergistic Roles of FAHD‐1 and PYC‐1 in Mitochondrial Function, Behavior, and Longevity in C. elegans

Advanced Biology, EarlyView.
FAHD‐1 and PYC‐1 catalyze opposing mitochondrial reactions that regulate oxaloacetate homeostasis in Caenorhabditis elegans. Using single and double knockouts, this study reveals that both enzymes shape locomotion, reproduction, respiration, and lifespan.

15) and from men with prostatovesiculitis 1.4 l 02/108 live cells/hr (SD ± 2.5, range 0-8.2; n = 13). The difference was significant (0.01 > p > 0.005). No significant difference was noted between the oxygen consumption of the spermatozoa in specimens from patients with decreased secretory function of the prostate gland (n = 13) or with asthenospermia
