Núria Tomás Corominas, Josep Arasa Martí CD6. Universitat Politècnica de Catalunya Rambla Sant Nebridi 10 08222 Terrassa [email protected] [email protected] Abstract A construction method to obtain sets of tailored facets to be used as the initial configuration in the design of freeform reflector surfaces is presented. The construction strategy starts from a collection of flat elementary facets a...

BACKGROUND The manner in which organizational downsizing is implemented can make a substantial difference as to whether the exposed workers will suffer from psychological ill health. Surprisingly, little research has directly investigated this issue. We examined the likelihood of psychological ill health associated with strategic and reactive downsizing. METHODS A cross-sectional survey inclu...

Many disease-associated variants identified by genome-wide association (GWA) studies are expected to regulate gene expression. Allele-specific expression (ASE) quantifies transcription from both haplotypes using individuals heterozygous at tested SNPs. We performed deep human transcriptome-wide resequencing (RNA-seq) for ASE analysis and expression quantitative trait locus discovery. We reseque...

Ruminants are a major reservoir of enterohaemorrhagic Escherichia coli (EHEC), which cause acute gastroenteritis in humans with potentially life-threatening sequelae. The mechanisms underlying EHEC persistence in ruminant hosts are poorly understood. EHEC produce several cytotoxins that inhibit the proliferation of bovine lymphocytes in vitro and influence EHEC persistence in calves, suggesting...

PE-35 mouse monoclonal antibody (MoAb) (IgG1) detecting an epithelial antigen with a molecular weight of 35,000 was characterized serologically. Immunoperoxidase staining and double immunoenzymatic staining showed that PE-35 antigen is predominantly on nonlymphoid cells in the medulla of thymus. By immunoelectron microscopy, thymic epithelial cells in the medulla were positive with PE-35 MoAb, ...

To determine events that transpire during the earliest stages of human T cell development, we have studied fetal tissues before (7 wk), during (8.2 wk), and after (9.5 wk to birth) colonization of the fetal thymic rudiment with hematopoietic stem cells. Calculation of the approximate volumes of the 7- and 8.2-wk thymuses revealed a 35-fold increase in thymic volumes during this time, with 7-wk ...

24 To explore the genetic diversity, host specificity and zoonotic potential of Enterocytozoon 25 bieneusi, feces from 348 stray and pet dogs, and 96 pet cats from different locations in China 26 were examined by internal transcribed spacer (ITS) based PCR. E. bieneusi was detected in 27 15.5% of dogs including 20.5% of stray dogs and 11.7% of pet dogs, and in 11.5% of pet 28 cats. Higher infec...

The prevalence of eight mutations in 84 patients with beta-thalassaemia major and in 16 subjects with thalassaemia intermedia was investigated. All of the patients were Italian, originating from Eastern Sicily (Messina area) and some Calabrian regions. Genomic DNA was amplified by polymerase chain reaction (PCR). DNA molecular investigations were performed by allele-specific oligonucleotide (AS...

The CD3(-)NKp46(+) phenotype is frequently used for the identification of natural killer (NK) cells in various mammalian species. Recently, NKp46 expression was analyzed in more detail in swine. It could be shown that besides CD3(-)NKp46(+) lymphocytes, a small but distinct population of CD3(+)NKp46(+) cells exists. In this study, we report low frequencies of CD3(+)NKp46(+) lymphocytes in blood...
