Real roots of random orthogonal polynomials with exponential weights
(2022-12-30)
We consider random orthonormal polynomials
σᴺ-dependent control of acid resistance and the locus of enterocyte effacement in enterohemorrhagic Escherichia coli is activated by acetyl phosphate in a manner requiring flagellar regulator FlhDC and the σS antagonist FliZ
(Wiley, 2014-08)
In enterohemorrhagic Escherichia coli (EHEC), sigma factor N (σᴺ) regulates glutamate-dependent acid resistance (GDAR) and the locus of enterocyte effacement (LEE); discrete genetic systems that are required for transmission ...
Heme and hemoglobin utilization by Mycobacterium tuberculosis
(Springer Nature, 2019-09-18)
Iron is essential for growth of Mycobacterium tuberculosis (Mtb), but most iron in the human body is stored in heme within hemoglobin. Here, we demonstrate that the substrate-binding protein DppA of the inner membrane Dpp ...
Plasmodium falciparum: Release of circumsporozoite protein by sporozoites in the mosquito vector
(Elsevier BV, 1992)
The release of circumsporozoite (CS) protein by Plasmodium falciparum sporozoites was investigated to identify factors regulating this process within infected Anopheles gambiae mosquitoes. The potential for sporozoites to ...
Fabrication of hierarchical Lewis acid Sn-BEA with tunable hydrophobicity for cellulosic sugar isomerization
(Elsevier, 2019-04)
Lewis acid Sn-BEA catalysts with tunable morphology and hydrophobicity were successfully synthesized by the recrystallization of post-synthetic Sn-BEA in the presence of ammonium fluoride (NH4F) and tetraethylammonium ...
Genetic modification of alternative respiration in Nicotiana benthamiana affects basal and salicylic acid-induced resistance to potato virus X
(BioMed Central, 2011-02-28)
Background: Salicylic acid (SA) regulates multiple anti-viral mechanisms, including mechanism(s) that may be negatively regulated by the mitochondrial enzyme, alternative oxidase (AOX), the sole component of the alternative ...
Development of an in-situ system and analysis procedure for measuring ground thermal properties
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2000)
Determination of the ground’s thermal conductivity is a significant challenge facing designers of Ground Source Heat Pump (GSHP) systems applied in commercial buildings. The number of boreholes and the depth and cost of ...
inlA premature stop codons are common among Listeria monocytogenes isolates from foods and yield virulence-attenuated strains that confer protection against fully virulent strains
(American Society for Microbiology, 2008-11)
Previous studies showed that a considerable proportion of Listeria monocytogenes isolates obtained from foods carry a premature stop codon (PMSC) mutation in inlA that leads to production of a truncated and secreted InlA. ...
Population dynamics of Plasmodium falciparum sporogony in laboratory-infected Anopheles gambiae
(American Society of Parasitologists, 1992)
The population dynamics of cultured Plasmodium falciparum parasites was examined during their sporogonic development in Anopheles gambiae mosquitoes. Estimates of absolute densities were determined for each life stage, and ...
In vivo assessment of diet-induced rat hepatic steatosis development by percutaneous single-fiber spectroscopy detects scattering spectral changes due to fatty infiltration
(SPIE, the international society for optics and photonics, 2015-11-05)
This study explores percutaneous single-fiber spectroscopy (SfS) of rat livers undergoing fatty infiltration. Eight test rats were fed a methionine-choline-deficient (MCD) diet, and four control rats were fed a normal diet. ...
