Peripheral glia and neurons jointly regulate activity-induced synaptic remodeling at the Drosophila neuromuscular junction [PDF]
In the nervous system, reliable communication depends on the ability of neurons to adaptively remodel their synaptic structure and function in response to changes in neuronal activity.

Cloning of SHV-2, OHIO-1, and OXA-6 beta-lactamases and cloning and sequencing of SHV-1 beta-lactamase [PDF]
Molecular cloning of DNA fragments permitted the isolation of structural genes coding for SHV-1, SHV-2, OHIO-1, and OXA-6 beta-lactamases. DNA probes were constructed for SHV-1, and under conditions of high stringency, hybridization was observed only between SHV-1 and SHV-2. Oligonucleotide typing with a 15-mer SHV-1 probe was capable of discriminating

High burden and genetic diversity of β-lactamase-producing Escherichia coli and Klebsiella pneumoniae causing community-acquired urinary tract infections in Southeastern Gabon. [PDF]
BackgroundThe increasing prevalence of β-lactamase-producing Escherichia coli and Klebsiella pneumoniae in community-acquired urinary tract infections (CA-UTIs) represents a growing public health challenge in low-resource settings.

Resistance of bacteria to 3rd generation cephalosporins mediated by beta-lactamases (ESBL, pAmpC) is a public health concern. In this study, 1517 phenotypically cephalosporin-resistant E. coli were screened for the presence of blaSHV genes.

Nucleotide sequence of SHV-2 beta-lactamase gene [PDF]
The nucleotide sequence of plasmid-mediated beta-lactamase SHV-2 from Salmonella typhimurium (SHV-2pHT1) was determined. The gene was very similar to chromosomally encoded beta-lactamase LEN-1 of Klebsiella pneumoniae. Compared with the sequence of the Escherichia coli SHV-2 enzyme (SHV-2E.coli) obtained by protein sequencing, the deduced amino acid ...

Nucleotide sequence and phylogeny of SHV-2 beta-lactamase [PDF]
We determined the nucleotide sequence of the blaSHV-2(pBP60-1) gene from Klebsiella ozaenae which confers resistance to broad-spectrum cephalosporins. The structural gene encodes a polypeptide product of 286 amino acids, and the estimated molecular weight of the mature protein is 28,900.

The Subjective Visual Vertical and the Subjective Haptic Vertical Access Different Gravity Estimates. [PDF]
The subjective visual vertical (SVV) and the subjective haptic vertical (SHV) both claim to probe the underlying perception of gravity. However, when the body is roll tilted these two measures evoke different patterns of errors with SVV generally ...

Single amino acid substitution between SHV‐1 β‐lactamase and cefotaxime‐hydrolyzing SHV‐2 enzyme [PDF]
SHV‐2 β‐lactamase was purified from an overproducing variant of a clinical isolate of Escherichia coli resistant to cefotaxime. Pure protein was digested by trypsin and Lys‐C endoproteinase. Proteolytic peptides, isolated by reverse‐phase HPLC, were submitted to manual Edman degradation and aligned by homology with the sequence of SHV‐1 β‐lactamase.
