A series of metallosupramolecular architectures have been prepared including rectangles, prisms and cages, and featuring half-sandwich rhodium(III) fragments at the vertices. Remarkably, a stable cage-like heteropolymetallic complex possessing eight rhodium(III) and two silver(I) metal ions (3) has been obtained following a multistep procedure. The RhIII/AgI mixed macrocage enables the separation of dihalogenated benzene derivatives with high selectivity. Furthermore, a detailed X-ray crystallographic study confirmed that the discriminative encapsulation of para-dihalobenzene (dichlorobenzene, dibromobenzene and diiodobenzene) is favored by Ag-π interactions and steric effects...

Central nervous system diseases are not currently diagnosed based on knowledge of biological mechanisms underlying their symptoms. Greater understanding may be offered through an agnostic approach to traditional disease categories, where learning more about shared biological mechanisms across conditions could potentially reclassify sub-groups of patients to allow realisation of more effective treatments. This review represents the output of the collaborative group "PRISM", tasked with considering assay choices for assessment of attention and working memory in a transdiagnostic cohort of Alzheimer's disease and schizophrenia patients exhibiting symptomatic spectra of social withdrawal...

The resolution of inflammation is an active process that is coordinated by endogenous mediators. Previous studies have demonstrated the immunomodulatory properties of the axonal guidance proteins in the initial phase of acute inflammation. We hypothesized that the neuronal guidance protein neogenin (Neo1) modulates mechanisms of inflammation resolution. In murine peritonitis, Neo1 deficiency (Neo1-/-) resulted in higher efficacies in reducing neutrophil migration into injury sites, increasing neutrophil apoptosis, actuating PMN phagocytosis, and increasing the endogenous biosynthesis of specialized proresolving mediators, such as lipoxin A4, maresin-1, and protectin DX...

BioMarin Pharmaceutical is developing pegvaliase (PALYNZIQ™) as a treatment for phenylketonuria, a genetic disorder caused by deficiency of phenylalanine hydroxylase which leads to neurotoxic accumulation of phenylalanine. Data from the phase III PRISM clinical trial program indicate treatment with pegvaliase is associated with sustained reductions in blood phenylalanine levels and sustained improvements in neurological sequelae in patients with phenylketonuria. Based on these positive results pegvaliase was recently approved in the US for adults with phenylketonuria who have uncontrolled blood phenylalanine concentrations on current treatment...

The mini fungal lectin PhoSL was recombinantly produced and characterized. Despite a length of only 40 amino acids, PhoSL exclusively recognizes N-glycans with α1,6-linked fucose. Core fucosylation influences the intrinsic properties and bioactivities of mammalian N-glycoproteins and its level is linked to various cancers. Thus, PhoSL serves as a promising tool for glycoprofiling. Without structural precedence, the crystal structure was solved using the zinc anomalous signal, and revealed an interlaced trimer creating a novel protein fold termed β-prism III...

This study evaluates whether three commonly used pediatric intensive care unit (PICU) severity of illness scores, pediatric risk of mortality score (PRISM) III, pediatric index of mortality (PIM) 2, and pediatric logistic organ dysfunction (PELOD), are the appropriate tools to discriminate mortality risk in children receiving extracorporeal membrane oxygenation (ECMO) support for respiratory failure. This study also evaluates the ability of the Pediatric Risk Estimate Score for Children Using Extracorporeal Respiratory Support (Ped-RESCUERS) to discriminate mortality risk in the same population, and whether Ped-RESCUERS' discrimination of mortality is improved by additional clinical and laboratory measures of renal, hepatic, neurologic, and hematologic dysfunction...
