Three isolates of feline calicivirus (FCV) designated NADC, KCD and CFI/68 were compared for biochemical, serological and genetic variation within the capsid protein gene. The M(r) of the capsid protein from purified virions was approximately 66,000 for the NADC virus isolate, which differed slightly from the relative mobilities of the purified capsid proteins of the KCD and CFI/68 isolates. Po...

hydrogen bonds between C-3 OH and the carboxyl. It seems difficult to invoke an intermolecular hydrogen bond without having some sort of added hydrophobic contribution in aqueous solution. This kind of effect has been observed in aliphatic carboxylic acids-larger aliphatic chains leading to stronger dimerization effects in aqueous solution.32 To describe the 13C NMR shifts as due to intermolecu...

Methylene blue (MB) is a hydrophobic drug molecule, having importance both as a staining reagent and pharmaceutical agent. MB is strongly fluorescent, with an emission peak at 686 nm (λex 665 nm). In the study, the possibility of MB as an extrinsic fluorophore to study the micellization behavior of bile salts (BSs) was carried out. Since BSs are drug delivery systems, the solubilization of hydr...

The two main steps of the membranolytic activity of detergents: 1) the partitioning of detergent molecules in the membrane and 2) the solubilisation of the membrane are systematically investigated. The interactions of two bile salt molecules, sodium cholate (NaC) and sodium deoxycholate (NaDC) with biological phospholipid model membranes are considered. The membranolytic activity is analysed as...

Purpose: The purpose of this study is to compare the diagnostic accuracy of prostate apparent diffusion coefficient (ADC) versus normalized prostate ADC using the normal peripheral zone as the reference site for the differentiation of prostate cancer and prostatitis in the peripheral zone. Methods: Fifty-two patients, 32 with prostate cancer and 19 with prostatitis, were assessed with single-sh...

The advent of combination antiretroviral treatment (cART) has been followed by a decrease in HIV-associated morbidity and mortality, but also by an apparent increase in the incidence of non-AIDS-defining cancers (NADCs). The risk of lung cancer is substantially higher in HIV-infected patients than in the general population, in part due to aging and tobacco use, and it is the most frequent NADC....

BACKGROUND We aimed to assess cancer incidence and mortality for all-causes and factors related to risk of death in an Italian cohort of HIV infected unselected patients as compared to the general population. METHODS We conducted a retrospective (1986-2012) cohort study on 16 268 HIV infected patients enrolled in the MASTER cohort. The standardized incidence ratios (SIRs) and standardized mor...

BACKGROUND Although the contrast-enhancing (CE) lesion on T1-weighted MR images is widely used as a surrogate for glioblastoma (GBM), there are also non-enhancing regions of infiltrative tumor within the T2-weighted lesion, which elude radiologic detection. Because non-enhancing GBM (Enh-) challenges clinical patient management as latent disease, this study sought to characterize ex vivo metabo...

BACKGROUND This retrospective survey describes types of cancers diagnosed in HIV-infected subjects in Asia, and assesses risk factors for cancer in HIV-infected subjects using contemporaneous HIV-infected controls without cancer. METHODS TREAT Asia HIV Observational Database (TAHOD) sites retrospectively reviewed clinic medical records to determine cancer diagnoses since 2000. For each diagno...

The guaC (GMP reductase), nadC (quinolinate phosphoribosyltransferase), and aroP (aromatic amino acid permease) genes of Escherichia coli K-12 were located in the 2.5-min region of the chromosome (muT-guaC-nadC-aroP-aceE) by a combination of linkage analysis, deletion mapping, restriction analysis, and plasmid subcloning. The guaC locus expressed a product of Mr 37,000 with a clockwise transcri...
