The goal of this article is to give a Lefschetz type decomposition for the cd-index of a complete fan. To a complete simplicial fan one can associate a toric variety X, the even Betti numbers hi of X and the numbers gi = hi − hi−1. If the fan is projective, then non-negativity of gi follows from the Lefschetz decomposition of the cohomology. In the case of a nonsiplicial complete fan one can an...

OBJECTIVE 1. To evaluate the percentage of caspase-3 and CD-34 expression on adenocarcinoma; 2. to quantify caspase-3 and CD-34 in tumor cells; 3. to verify the relationship between biomarkers and its malignancy; 4. to correlate biomarkers themselves. METHODS Thirty-eight human malignant prostate specimens, Gleason's score, were immunohistochemically stained for caspase-3 and CD-34 protein. Q...

BACKGROUND AND OBJECTIVE Serological screening enables us to detect patients of celiac disease (CD) before they develop serious complications. This study was planned to assess the prevalence of CD in the family members of index cases by serological screening. PATIENTS AND METHODS A prospective study was conducted on 50 children diagnosed to be having CD. Serological screening of the family me...

Extraintestinal manifestations (EIMs) cause increased morbidity and decreased quality of life in Crohn disease (CD). Ankylosing spondylitis (AS) belongs to EIMs. Very little is known on the clinical features of CD concomitant with AS. This study is to investigate the clinical features of CD patients with AS.We retrospectively collected all CD patients with AS in our hospital, and established a ...

BACKGROUND Conduct disorder (CD), a psychiatric index of antisocial behaviour, shares similarities with delinquency, a criminological index. This study sought to examine which factors in childhood predict a repeated diagnosis of CD in adolescence, and whether self-reported delinquent acts enhance the utility of symptoms of CD in predicting later persistent CD. METHOD Longitudinal data used in...

The potential ecological and human health risk related with urban street dust from urban areas of Tianjin, China was quantitatively analyzed using the method of toxicity characteristic leaching procedure (TCLP) and simple bioaccessibility extraction test (SBET). In the study, Hakason index, Nemerow index (P), the hazard index (HI) and the cancer risk index (RI) were calculated to assess the pot...

BACKGROUND We have previously demonstrated that patients with Crohn's disease (CD) of long duration have signs of autonomic neuropathy. The aim of this study was to examine whether autonomic neuropathy is an early manifestation of CD, or a sign appearing late in the course. METHODS Twenty patients, median age 40 years, with a short duration of CD were included. Examination of autonomic reflex...
