The HOT lanes concept relies on the assumption that SOVs will be discouraged from entering HOT lanes as toll rates increase, thus preventing HOT lanes from becoming congested. Most willingnessto-pay research has either focused on stated preference (SP) surveys (3) or investigated the median cost per hour of commute time saved (4). Although SP studies have been shown to be inaccurate in determin...

BACKGROUND TP53 mutations are among the most common mutations found in lung cancers, identified as an independent prognostic factor in many types of cancers. The purpose of this study was to investigate the frequency and prognostic impact of TP53 mutations in never-smokers and in different histological subtypes of lung cancer. METHODS We analyzed tumor tissue from 394 non-small cell carcinoma...

OBJECTIVE To investigate the risk of hepatotoxicity after initiation of protease inhibitor-containing highly active antiretroviral therapy (HAART) for HIV-1 infected patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) co-infection. DESIGN Retrospective study with 394 HIV-1-infected patients initiating HAART at a single university clinic. METHODS Liver enzyme elevation (...

La grossesse quadruple hétérotopique est exceptionnelle. La revue de la littérature en parle très peu. Les auteurs rapportent 1 cas de grossesse hétérotopique quadruple développée jusqu'à 34 semaines d'aménorrhée (3 fœtus intra utérins et 1 fœtus abdominal). Les fœtus intra utérins étaient diagnostiqués à l'échographie alors que le fœtus intra abdominal était de découverte opératoire. 3 jumeaux...

Surface enhanced Raman spectroscopy (SERS) has been increasingly utilized as an analytical technique with significant chemical and biological applications (Qian et al 2008 Nat. Biotechnol. 26 83; Fujita et al 2009 J. Biomed. Opt. 14 024038; Chou et al 2008 Nano Lett.8 1729; Culha et al 2003 Anal. Chem. 75 6196; Willets K A 2009 Anal. Bioanal.

BACKGROUND Sexual violence is one of the most prevalent but underreported incidents. One among many consequences of sexual violence is unwanted pregnancy. OBJECTIVES To describe events related to and factors associated with sexual violence among women with unwanted pregnancy and describe knowledge and use of contraception among these women with unwanted pregnancy. METHODS This cross-section...

The molecular basis of pathogenicity of the chicken anaemia virus (CAV) needs to be clarified in order to develop a safe, live virus vaccine. In this study, several high- and low-pathogenic infectious DNA clones were obtained from field virus samples after 12 or 38 passages in MDCC-MSB1 cells. The high-pathogenic clones induced a low haematocrit, low weight gain and high mortality. Nucleotide s...

The purpose of this study was to assess the association between human T-lymphotropic virus 1 (HTLV-1) and a lifetime history of active tuberculosis (TB) among relatives of HTLV-1-infected patients. We reviewed clinical charts of all relatives of HTLV-1-infected index cases who attended our institute in Lima from 1990-2004. The data of 1233 relatives was analysed; 394 (32.0%) were HTLV-1 positiv...

Late-onset Alzheimer's disease (LOAD) is a multifactorial disorder with over twenty loci associated with disease risk. Given the number of genome-wide significant variants that fall outside of coding regions, it is possible that some of these variants alter some function of gene expression rather than tagging coding variants that alter protein structure and/or function. RegulomeDB is a database...

The capsid proteins of adeno-associated viruses (AAV) have five conserved cysteine residues. Structural analysis of AAV serotype 2 reveals that Cys289 and Cys361 are located adjacent to each other within each monomer, while Cys230 and Cys394 are located on opposite edges of each subunit and juxtaposed at the pentamer interface. The Cys482 residue is located at the base of a surface loop within ...
