Widespread white matter (WM) abnormalities have been found in patients with schizophrenia. Corpus callosum (CC) is the key area that connects the left and right brain hemispheres. However, the results of studies considering different subregions of the CC as regions of interest in patients with schizophrenia have been inconsistent. To obtain a more consistent evaluation of the diffusion characte...

background: henoch-schönlein purpura (hsp) is an lga mediated small vessel systemic vasculitis disease in children. the etiology and pathogenesis of hsp disease remain unknown. however, environmental and genetic risk factors could play important roles in susceptibility to hsp disease. in this study we investigated the association of 5՛-untranslated region polymorphism (-634g/c) of vegf gene wit...

Very low birth weight (VLBW: ≤ 1500 g) individuals have an increased risk of white matter alterations and neurodevelopmental problems, including fine and gross motor problems. In this hospital-based follow-up study, the main aim was to examine white matter microstructure and its relationship to fine and gross motor function in 31 VLBW young adults without cerebral palsy compared with 31 term-bo...

Homer is a neuronal immediate early gene (IEG) that is enriched at excitatory synapses and binds group 1 metabotropic glutamate receptors (mGluRs). Here, we characterize a family of Homer-related proteins derived from three distinct genes. Like Homer IEG (now termed Homer 1a), all new members bind group 1 mGluRs. In contrast to Homer 1a, new members are constitutively expressed and encode a C-t...

The purpose of this study was to evaluate the accuracy of the respective dies after polyether elastomeric procedure in the presence or absence of cervical contact of the acrylic resin shell with the cervical region, establishing a comparison to dies obtained with stock trays. This study consisted of three groups with 10 specimens each: 1) acrylic copings without cervical contact, (cn); 2) acryl...

background: to assess the usefulness of premature luteinization hormone (lh) surge prevention in an intrauterine insemination (iui) cycle by gnrh antagonist administration materials and methods: sixty patients with unexplained or mild male infertility or minimal to mild endometriosis were enrolled in this prospective randomized controlled trial. there were twenty patients in group a (with gnrh ...

BACKGROUND AND PURPOSE Many studies have observed atrophy and abnormal diffusion within the CC in MS. However, few studies have addressed whether such abnormalities appear at the earliest stage of MS, especially in CIS. In this study, we aimed to investigate the CC integrity and patterns of CC abnormalities in CIS with diffusion tensor group tractography. MATERIALS AND METHODS First, probabil...

Objective To compare Roux-en-Y hepatico-jejunostomy with complete resection of the cyst or incomplete resection with 1-cm remnant proximal cyst wall in treating adult type I choledochal cyst (CC). Methods The medical records of 267 adult patients with type I CC from January 1998 to December 2015 were reviewed retrospectively. Among them, 171 underwent Roux-en-Y hepatico-jejunostomy with compl...

The increase in software complexity introduced the need for software development teams and consequently the need to coordinate team members’ activities and create a shared awareness. We seek to overcome some the pitfalls of earlier attempts to coordinate software development through a new coordination paradigm we term Continuous Coordination (CC). Generally speaking, the CC paradigm complements...

Background: one of the leading clinical problems for premature neonates especially with very low birth weight is the type and amount of feeding. The authors aimed to compare outcomes of slow versus rapid feeding in premature neonates hospitalized in Al-Zahra hospital, Rasht. Methods: This is a clinical trial that was conducted on 62 premature neonates aged less than 35 weeks of gestation who w...
