Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Background: We aimed to determine the plausible role of high body mass index (BMI) in the etiopathogenesis of coronary artery disease (CAD), erosive esophagitis (EE) and gastroesophageal reflux disease (GERD) and their complex associations.

Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Organoids in pediatric cancer research
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
