Ice plant (Mesembryanthemum crystallinum L.) is a halophyte and an inducible CAM plant. Ice plant seedlings display moderate salt tolerance, with root growth unaffected by 200 mM NaCl treatments, though hypocotyl elongation is hindered in salt-stressed etiolated seedlings.

Given the influence of cognitive abilities on life outcomes, there is inherent value in identifying genes involved in controlling learning and memory. Further, cognitive dysfunction is a core feature of many neuropsychiatric disorders. Here, we use a combinatory in silico approach to identify human gene targets that will have an especially high likelihood of individually and directly impacting cognition.

The natural product MGN-3 (Biobran) is a defatted, partially hydrolysed rice bran-derived hemicellulose enzymatically modified with an extract of . It has a high proportion of arabinoxylan. It has a protective action against intracerebroventricular streptozotocin-induced murine sporadic Alzheimer's disease and reverses spatial memory deficit in this disease model.

Allosteric regulation is a powerful mechanism for controlling the efficiency of enzymes. Deciphering the evolutionary mechanisms by which allosteric properties have been acquired in enzymes is of fundamental importance. We used the malate (MalDH) and lactate deydrogenases (LDHs) superfamily as model to elucidate this phenomenon.

Poor blood pressure control in treated patients with hypertension is an important topic in the field of hypertension, and an unmet need for new therapeutic drugs remains. Soluble guanylate cyclase (sGC), a key signal transduction enzyme responsible for vasodilation, has attracted increasing interest as a therapeutic target in various cardiovascular diseases. Two different sGC agonists, sGC stimulators and activators, can increase its enzymatic activity in reduced and oxidized/apo forms, respectively.
