Major histocompatibility complex (MHC) class I deficiency syndrome is a rare primary immunodeficiency caused by mutations in the peptide transporter complex associated with antigen presentation (TAP) gene which plays a crucial role in intracellular peptide antigen presentation. A few cases have been reported to date. Recurrent sinopulmonary infections and skin ulcers are main characteristics of the syndrome. Here we report two siblings diagnosed with TAP1 deficiency syndrome associated only with recurrent sinopulmonary infections with the description of a novel mutation leading to a premature stop codon in TAP1 gene and review of the relevant literature...

The epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor gefitinib was initially approved in Japan in 2002 for the treatment of advanced or metastatic non-small-cell lung cancer (NSCLC); however, the optimal order of conventional cytotoxic chemotherapy (carboplatin and paclitaxel) and gefitinib administration has not been determined. We conducted a randomized phase II study of carboplatin and paclitaxel followed by gefitinib vs. gefitinib followed by carboplatin and paclitaxel to select a candidate for further development in a phase III study of chemotherapy-naïve patients with advanced or metastatic NSCLC, regardless of their EGFR mutation status...

Chronic hepatitis B virus (HBV) infection leads to a risk of developing cirrhosis and hepatocellular carcinoma. In France, where the prevalence of HBV is low, mother-to-child transmission is the cause of chronic infection in more than one-third of cases. After exposure, the risk of chronic infection is the highest for newborns (90 %). The World Health Organization implemented a global immunization program in 1991, applied in France in 1994. A significant number of children are infected each year, however, and failure of postexposure prophylaxis is reported in 4-10 % of newborns...

BACKGROUND: The increased incidence of obesity and associated metabolic diseases has driven research focused on genetically or pharmacologically alleviating metabolic dysfunction. These studies employ a range of fasting-refeeding models including 4-24 h fasts, "overnight" fasts, or meal feeding. Still, we lack literature that describes the physiologically relevant adaptations that accompany changes in the duration of fasting and re-feeding. Since the liver is central to whole body metabolic homeostasis, we investigated the timing of the fast-induced shift toward glycogenolysis, gluconeogenesis, and ketogenesis and the meal-induced switch toward glycogenesis and away from ketogenesis...

Proposals are described for the assignment of recently reported viruses, infecting rodents, bats and other mammalian species, to new species within the Hepacivirus and Pegivirus genera (family Flaviviridae). Assignments into 14 Hepacivirus species (Hepacivirus A-N) and 11 Pegivirus species (Pegivirus A-K) are based on phylogenetic relationships and sequence distances between conserved regions extracted from complete coding sequences for members of each proposed taxon. We propose that the species Hepatitis C virus is renamed Hepacivirus C in order to acknowledge its unique historical position and so as to minimize confusion...
