Acute kidney injury (AKI) is a common complication of neonatal encephalopathy (NE). The accurate diagnosis of neonatal AKI, irrespective of the cause, relies on suboptimal methods such as identification of rising serum creatinine, decreased urinary output and glomerular filtration rate. Studies of AKI biomarkers in adults and children have shown ...

MicroRNAs (miRNAs) are endogenously expressed small non-coding RNAs, which are evolutionarily conserved and function as regulators of gene expression. These molecules are involved in numerous biological processes including differentiation, development, proliferation and apoptosis. Further investigation identifies that miRNAs may act as either potent oncogenes or tumor-suppressor genes, linking to cancer ...

An observable constraint on climate sensitivity, based on variations in mid-tropospheric relative humidity (RH) and their impact on clouds, is proposed. We show that the tropics and subtropics are linked by teleconnections that induce seasonal RH variations that relate strongly to albedo (via clouds), and that this covariability is mimicked ...

Parkinson's disease (PD) is a pathological condition characterized by a progressive neurodegeneration of dopaminergic neurons with the consequent reduction of dopamine content in the substantia nigra. The neurotoxin 6-hydroxydopamine (6-OHDA) is widely used to mimic the neuropathology of PD in both in vivo and in vitro experimental models. We found ...

Planarians are members of the Platyhelminthes (flatworms). These animals have evolved a remarkable stem cell system. A single pluripotent adult stem cell type ("neoblast") gives rise to the entire range of cell types and organs in the planarian body plan, including a brain, digestive-, excretory-, sensory- and reproductive systems. Neoblasts ...

The hyperthermophile Pyrococcus furiosus catalyses the hydrogenation of a broad range of carboxylic acids selectively to the corresponding primary alcohols. Other functional groups such as isolated C[double bond, length as m-dash]C-double bonds are not touched. The chemoselectivity of the carboxylate reduction may be directed towards aldehydes by simple medium engineering.

The time course of attention is a major characteristic on which different types of attention diverge. In addition to explicit goals and salient stimuli, spatial attention is influenced by past experience. In contextual cueing, behaviorally relevant stimuli are more quickly found when they appear in a spatial context that has ...

Does mental rotation depend on the readiness to act? Recent evidence indicates that the involvement of motor processes in mental rotation is experience-dependent, suggesting that different levels of expertise in sensorimotor interactions lead to different strategies to solve mental rotation problems. Specifically, experts in motor activities perceive spatial material as ...

The electronic structure of the newly discovered superconductor KNi(2)Se(2) is studied by first-principles calculations. Our results show that its ground state is a quasi-two-dimensional metal and the Fermi surface is contributed by the Ni 3d and Se 4p states. These states determine the significant physical properties of the heavy-fermion superconductor ...

PURPOSE: In spina bifida aperta (SBA), the "second-hit hypothesis" addresses consequences by delayed neurological damage superimposed upon the congenital myelomeningocele (MMC). This secondary damage is postulated to underlie the disappearance of leg movements shortly after birth. Innovative fetal surgery might prevent this, but results are methodologically hard to prove in ...

Microcystins, the most prevalent cyanotoxins occurring worldwide, were first recorded in the species Microcystis aeruginosa. Its production has been reported in all continents; thus, we propose a comprehensive phylogenetic study to characterize M. aeruginosa microcystin-producing strains and establish whether or not the species has an historic biogeography. To accomplish this, ...

Corals in the genus Acropora generate much of the structural complexity upon which coral reefs depend, but they are susceptible to damage from toxic seaweeds. Acropora nasuta minimizes this damage by chemically cuing symbiotic goby fishes (Gobiodon histrio or Paragobiodon echinocephalus) to remove the toxic seaweed Chlorodesmis fastigiata. Within minutes ...
