PURPOSE To determine the element that modulates benzalkonium chloride (BAC) toxicity by using a new electrophysiological method to evaluate acute corneal barrier dysfunction induced by travoprost Z with sofZia (Travatan Z(®)), travoprost with 0.015% BAC (Travatan(®)), and its additives. METHODS Corneal transepithelial electrical resistance (TER) was measured in live white Japanese rabbits by ...

Here we describe the cloning of a sequenced WUMS isolate of murine gammaherpesvirus-68 (MHV-68, γHV-68, also known as MuHV-4) as a bacterial artificial chromosome (BAC). We engineered the insertion of the BAC sequence flanked by loxP sites into the left end of the viral genome before the M1 open reading frame. The infectious viruses were reconstituted following transfection of the MHV-68 BAC DN...

BACKGROUND Limited brachial artery (BA) flow-mediated dilation during brachial artery reactivity testing (BART) has been linked to increased cardiovascular risk. We report on the phenomenon of BA constriction (BAC) following hyperemia. OBJECTIVES To determine whether BAC predicts adverse CV outcomes and/or mortality in the women's ischemic Syndrome Evaluation Study (WISE). Further, as a secon...

INTRODUCTION Bronchioloalveolar carcinoma (BAC) is a unique subtype of non-small cell lung cancer (NSCLC) that is associated with female gender, Asian ethnicity, and never-smoking status. Although BAC is commonly reported to occur more frequently in young people with lung cancer, there is a lack of evidence to support this association. METHODS We analyzed the association between age at diagno...

Background The aim of this study was to determine if breast arterial calcification (BAC) on mammography predicts myocardial ischemia (MI) on stress myocardial perfusion single-photon emission computed tomography (MPS). BAC is a type of medial artery calcification that can be seen incidentally on mammography, but the relationship between coronary artery calcification and MI on MPS is yet unknown...

Although certain neoplasms are unique to man, others occur across species. One such neoplasm is bronchioloalveolar lung carcinoma (BAC), a neoplasm of the Type II pneumocyte that affects humans, sheep, and small animals (dogs and cats). Human BAC occurs largely in nonsmokers. Sheep BAC is caused by the jaagsiekte retrovirus and is endemic and contagious. Feline BAC is neither endemic nor contag...

The current investigation aimed to generate data to inform the development of risk assessments of biocide usage. Stabilized domestic drain biofilm microcosms were exposed daily over 6 months to increasing concentrations (0.01% to 1%) of the biocide benzalkonium chloride (BAC) in a simple aqueous solution (BAC-s) or in a complex formulation (BAC-f) representative of a domestic cleaning agent. Bi...

Artisanal cheeses are prepared using traditional methods with territorial, regional and cultural linkages. In Brazil, there is a great diversity of artisanal (BAC), which have historical, socioeconomic importance. The the BAC between producing regions due to different compositions raw milk, steps involved in process maturation time. crucial step for cheese differentiation non-addition starter c...

Bacterial artificial chromosome (BAC) vectors enable stable cloning of large DNA fragments from single genomes or microbial assemblages. A novel shuttle BAC vector was constructed that permits replication of BAC clones in diverse Gram-negative species. The "Gram-negative shuttle BAC" vector (pGNS-BAC) uses the F replicon for stable single-copy replication in E. coli and the broad-host-range RK2...
