Although allelic diversity of genes has been shown to contribute to many phenotypic variations associated with different physiological processes in plants, information on allelic diversity of abiotic stress-responsive genes is limited. Here it is shown that the alleles OsWRKY45-1 and OsWRKY45-2 play different roles in abscisic acid (ABA) signalling and ...

Polypharmacy is a problem of growing interest in geriatrics with the increase in drug consumption in recent years, particularly among people aged >65 years. The main reasons for polypharmacy are longer life expectancy, co-morbidity and the implementation of evidence-based clinical practice guidelines. However, polypharmacy also has important negative consequences, such ...

Suprasellar arachnoid cysts (SACs) are rare, comprising approximately 10% of all intracranial arachnoid cysts. Although neuroendoscopic management is emerging as a safe effective alternative to microsurgery, the type of endoscopic surgery whether ventriculocystostomy (VC) or ventriculocystocisternostomy (VCC) is still controversial. This study evaluates the role of endoscopy in the treatment ...

Blood vessel networks are typically formed by angiogenesis, a process in which new vessels form by sprouting of endothelial cells from pre-existing vessels. This process is initiated by vascular endothelial growth factor (VEGF)-mediated tip cell selection and subsequent angiogenic sprouting. Surprisingly, we found that VEGF directly controls the expression of ...
