Why the Extended-Spectrum β-Lactamases SHV-2 and SHV-5 Are “Hypersusceptible” to Mechanism-Based Inhibitors [PDF]

Biochemistry, 2009
Extended-spectrum beta-lactamases (ESBLs) are derivatives of enzymes such as SHV-1 and TEM-1 that have undergone site-specific mutations that enable them to hydrolyze, and thus inactivate, oxyimino-cephalosporins, such as cefotaxime and ceftazidime.

Free factorization algebras and homology of configuration spaces in algebraic geometry

, 2017
We provide a construction of free factorization algebras in algebraic geometry and link factorization homology of a scheme with coefficients in a free factorization algebra to the homology of its (unordered) configuration spaces.

Diversity of SHV and TEM β-Lactamases in Klebsiella pneumoniae : Gene Evolution in Northern Taiwan and Two Novel β-Lactamases, SHV-25 and SHV-26 [PDF]

Antimicrobial Agents and Chemotherapy, 2001
ABSTRACT A total of 113 blood culture isolates of Klebsiella pneumoniae from 10 hospitals in northern Taiwan were studied for SHV and TEM β-lactamase production. bla SHV was amplified from all isolates by PCR.

Characterization of extended-spectrum β-lactamases produced by Escherichia coli isolated from hospitalized and nonhospitalized patients : emergence of CTX-M-15-producing strains causing urinary tract infections [PDF]

, 2010
Extended-spectrum β-lactamase-producing Escherichia coli isolates were obtained from hospitalised and non-hospitalised patients in Belgium between August 2006 and November 2007.

High-J CO emission in the Cepheus E protostellar outflow observed with SOFIA/GREAT

, 2012
We present and analyze two spectrally resolved high-J CO lines towards the molecular outflow Cep E, driven by an intermediate-mass class 0 protostar. Using the GREAT receiver on board SOFIA, we observed the CO (12--11) and (13--12) transitions (E_u ~ 430

The Frequency of Extended Spectrum β-Lactamase Genes of SHV-2a, SHV-5 and SHV-12 in Clinical Isolates of Klebsiella Pneumoniae Isolated from Kermanshah Medical Centers in 2014 [PDF]

Majallah-i dānishgāh-i ̒ulūm-i pizishkī-i Arāk, 2016
Background: The dissemination of extended-spectrum β-lactamases (ESBL) in Klebsiella pneumoniae isolates has resulted in the increase of antibiotic resistance and mortality among patients. The aim of this study was to determine the prevalence of ESBL and

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

A thermodynamical model for rainfall-triggered volcanic dome collapse [PDF]

, 2004
Dome-forming volcanic eruptions typically involve the slow extrusion of viscous lava onto a steep-sided volcano punctuated by collapse and the generation of hazardous pyroclastic flows.

Investigation of Klebsiella pneumoniae Isolates Producing SHV-12 and SHV-11 β-Lactamases in Korean Hospitals

Journal of Microbiology and Biotechnology, 2009
Of 143 clinical isolates of Klebsiella pneumoniae collected from Korean non-tertiary hospitals, 24 (16.8%) showed an extended-spectrum beta-lactamase-positive phenotype. PCR and sequence analysis revealed the presence of TEM-116 (n=13), CTX-M-3 (n=5), CTX-M-14 (n=2), CTX-M-15 (n=3), and SHV-12 (n=16).

Role of Asp104 in the SHV β-Lactamase [PDF]

Antimicrobial Agents and Chemotherapy, 2006
ABSTRACT Among the TEM-type extended-spectrum β-lactamases (ESBLs), an amino acid change at Ambler position 104 (Glu to Lys) results in increased resistance to ceftazidime and cefotaxime when found with other substitutions (e.g., Gly238Ser and Arg164Ser).
