Evidence from anatomical and functional imaging studies have highlighted major modifications of cortical circuits during adolescence. These include reductions of gray matter (GM), increases in the myelination of cortico-cortical connections and changes in the architecture of large-scale cortical networks. It is currently unclear, however, how the ongoing developmental processes impact upon the ...

Morphological features of the mid-palatal suture were studied in human foetuses from 4 to 9 months of intra-uterine life. The foetuses were divided into three age groups, GI (16-23 weeks), GII (24-31 weeks) and GIII (32-39 weeks). The mid-palatal suture in GI foetuses is rectilineal in form with a wide space between the palatal processes of the maxilla. The suture has a sinuous nature in GII an...

Gastrointestinal (GI) symptoms are a source of substantial morbidity for people with CF (PwCF), and their assessment treatment present an unmet need. We introduced 3 validated patient reported outcome measures (PROMS) questionnaires investigating GI into routine clinical assessment. evaluated the prevalence severity upper lower in our population. also assessed acceptability using GI-PROMS as to...

background: gastrointestinal and liver diseases (gild) are among the most common causes of morbidity and substantial proportion of mortality with enormous economic consequences in iran. we aimed to collect and report the most recent statistics on deaths, symptoms, physician visits, and hospitalizations for common gastrointestinal and liver diseases in gastrointestinal referral centers of tehran...

background: colonoscopy is used for both diagnostic as well as therapeutic purposes in patients with lower gi symptoms. the aim of this study was to assess the clinical manifestations and to determine the colonoscopic findings of children with lower gi symptoms attending a pediatric hospital in tehran. materials and methods: during a 5-year period (1996-2001), all children less than 16 years of...

We introduce the first class of perfect sampling algorithms for the steady-state distribution of multiserver queues with general interarrival time and service time distributions. Our algorithm is built on the classical dominated coupling from the past protocol. In particular, we use a coupled multi-server vacation system as the upper bound process and develop an algorithm to simulate the vacati...
