Cross-sectional associations between human papillomavirus (HPV), anal squamous intraepithelial lesions (SIL), and human immunodeficiency virus (HIV) were studied in a cohort of gay men. HPV DNA was detected by generic and type-specific polymerase chain reaction (PCR) probes and hybrid capture assay (HC). HPV virus load was estimated by HC relative light unit (RLU) ratio. HPV prevalence, number ...

The International Labor Organization (ILO) system for classifying chest radiographic changes related to inhalation of pathogenic dusts is predicated on film-screen radiography (FSR). Digital radiography (DR) has replaced FSR in many centers, but there are few data to indicate whether DR is equivalent to FSR in identifying and quantifying interstitial and pleural abnormalities. Furthermore, DR i...

BACKGROUND The ratio of two nicotine metabolites, cotinine and trans-3'-hydroxycotinine (3-HC), has been validated as a method of phenotyping the activity of the liver enzyme cytochrome P450 (CYP) 2A6 and, thus, the rate of nicotine metabolism. Our objective was to evaluate the correlates and stability of the 3-HC to cotinine ratio in ad libitum and reducing smokers, using nicotine replacement ...

Hypercortisolism (HC) is a common disease in dogs. This article will review the laboratory tests that are available for diagnosis of HC and laboratory tests for differentiating between causes of HC. An emphasis will be made on the clinical process that leads to the decision to perform those tests and common misconceptions and issues that arise when performing them. To choose between the adrenoc...

In the previous studies, the several halocarbons (HC) were tested as promoters for a Ti-based Ziegler-Natta (ZN) catalyst at different polymerization conditions. The Results showed that chloro cyclohexane has the best operation in catalyst activity, polymer particle size growth, hydrogen responsibility and wax reduction too. For the first time in this study, the effect of Al/Ti ratio on the opt...

We performed a case-control study to determine the association of BK plasma viremia with hemorrhagic cystitis (HC) in hematopoietic cell transplant (HCT) recipients. Thirty cases of HC (14 of which occurred after platelet engraftment with documented BK viruria [BK-HC]) were compared with matched controls. Weekly plasma samples were tested for BK virus DNA by polymerase chain reaction (PCR). BK ...

AIM To test a new assay for the detection of human papillomavirus (HPV) DNA, hybrid capture II (HC II), compared with the previous commercialized hybrid capture I (HC I) and polymerase chain reaction (PCR) results on cervical scrapes from fresh cone excision biopsy samples. METHODS The three methods were used on cervical scrapes from 42 fresh cone excision biopsy samples. There were nine meta...

OBJECTIVES We examined whether oral folate supplementation would rescue a hypercholesterolemia (HC)-related impairment of ischemia-induced angiogenesis. BACKGROUND Folate protects against endothelial dysfunction, but the effect of folate supplementation on angiogenesis is little known. METHODS Sprague-Dawley rats were divided into four groups. Control rats were fed a normal diet (n = 18); H...

We are exposed to millions of microbial and dietary antigens via the gastrointestinal tract, which likely play a key role in type 1 diabetes (T1D). We differentiated the effects of these two major environmental factors on gut immunity and T1D. Diabetes-prone BioBreeding (BBdp) rats were housed in specific pathogen-free (SPF) or germ-free (GF) conditions and weaned onto diabetes-promoting cereal...
