OBJECTIVE The Vermont Oxford Network (VON) CARE Group was formed in response to the need to create organizational cultures supportive of change and quality improvement. METHODS The CARE Group consisted of team members from 4 participating neonatal intensive care units (NICUs). All CARE Group members chose to work on multidisciplinary teamwork for the duration of the Neonatal Intensive Care Qu...

Stem cell migration and interaction with pathology are critical to understand the complexity and status of disease recovery progress. However, the dynamic visualization still remains a great challenge due to imaging technical limitation, cell labeling difficulty, or blood-brain barrier (BBB). Herein, fast photoacoustic tomography (PAT) with optical molecular probes is applied to noninvasively m...

INTRODUCTION The molecular mechanism underlying mitochondrial BAK activation during apoptosis remains highly controversial. Two seemingly conflicting models have been proposed. In one, BAK requires so-called activating BH3 only proteins (aBH3) to initiate its conformation change. In the other, displacement from inhibitory pro-survival BCL-2 proteins (PBPs) and monomerization of BAK by PBP selec...

The gene encoding penicillin-binding protein 4 (PBP 4) of Bacillus subtilis, pbpD, was cloned by two independent methods. PBP 4 was purified, and the amino acid sequence of a cyanogen bromide digestion product was used to design an oligonucleotide probe for identification of the gene. An oligonucleotide probe designed to hybridize to genes encoding class A high-molecular-weight PBPs also identi...

Penicillin-resistant strains of Streptococcus pneumoniae possess altered forms of penicillin-binding proteins (PBPs) with decreased affinity for penicillin. The PBP2B genes of these strains have a mosaic structure, consisting of regions that are very similar to those in penicillin-sensitive strains, alternating with regions that are highly diverged. Penicillin-resistant strains of viridans grou...

Ceftaroline is a new parenteral cephalosporin approved by the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA) for the treatment of complicated skin and soft tissue infections (cSSTIs) including those due to methicillin-resistant Staphylococcus aureus (MRSA), and community-acquired pneumonia (CAP). Ceftaroline has broad-spectrum activity against gram-positive and gr...

Excitatory synaptic transmission is mediated by ionotropic glutamate receptors (iGluRs) through the induced transient opening of transmembrane ion channels. The three-dimensional structure of the extracellular ligand-binding core of iGluRs shares the overall features of bacterial periplasmic binding proteins (PBPs). In both families of proteins, the ligand-binding site is arranged in two domain...

Male moths respond to conspecific female-released pheromones with remarkable sensitivity and specificity, due to highly specialized chemosensory neurons in their antennae. In Antheraea silkmoths, three types of sensory neurons have been described, each responsive to one of three pheromone components. Since also three different pheromone binding proteins (PBPs) have been identified, the antenna ...

Many receptors undergo ligand-induced conformational changes to initiate signal transduction. Periplasmic binding proteins (PBPs) are bacterial receptors that exhibit dramatic conformational changes upon ligand binding. These proteins mediate a wide variety of fundamental processes including transport, chemotaxis, and quorum sensing. Despite the importance of these receptors, no PBP antagonists...

This paper presents a new methodology combining multiple criteria sorting or ranking methods with project portfolio selection procedure. The multicriteria method permits the comparison of projects in terms their priority based on qualitative and quantitative criteria. Then, feasible set projects, i.e. portfolio, is selected according to defined by satisfying resources logical constraints. propo...
