OBJECTIVE To study the co-occurrence of psychiatric disorders (PD) and communication disorders (CD) and their relationship with global functioning in maltreated children and adolescents. METHODS The sample comprised 143 maltreated children and adolescents (55.8% male). All underwent clinical communication and psychiatric evaluations, as well as global functioning assessment using the Children...
OBJECTIVE to describe the experience at two tertiary centres during the first year of use of magnetic resonance enterography (MRE) for the management of Crohn's disease (CD): indications and influence of the technique in clinical decision making. MATERIALS AND METHODS retrospective descriptive study in which patients who underwent MRE were included consecutively. Epidemiological and clinical ...
OBJECTIVES Nonunion is one of the most troublesome complications to treat in orthopaedics. Former authors believed that atrophic nonunion occurred as a result of lack of mesenchymal stem cells (MSCs). We evaluated the number and viability of MSCs in site of atrophic nonunion compared with those in iliac crest. METHODS We enrolled five patients with neglected atrophic nonunions of long bones c...
Increased Cd toxicity at low salinity has been attributed to increased free Cd2+ ion concentration ([Cd2+]sw), but transfer to dilute seawater also stimulates physiological ionic regulation in crabs. In this study, Cd accumulation and Ca homeostasis in the shore crab (Carcinus maenas) were explored at fixed [Cd2+]sw to reveal the physiological events during sublethal Cd exposure. Crabs were exp...
OBJECTIVE The aim of this study was to investigate the prevalence of dental enamel defects, recurrent aphthous stomatitis (RAS) and caries experience and to measure salivary flow rate, buffer capacity, saliva and plaque pH and salivary cariogenic microflora in patients with celiac disease (CD) compared to healthy subjects. SUBJECTS AND METHODS Thirty-five patients, aged 6-19 years, with a dia...
The unfolding kinetics of horse cytochrome c in the oxidized state has been studied at 10, 22, and 34 degreesC as a function of guanidine hydrochloride (GdnHCl) concentration. Rapid (millisecond) measurements of far-UV circular dichroism (CD) as well as fluorescence quenching due to tryptophan to heme excitation energy transfer have been used to monitor the unfolding process. At 10 degreesC, th...
هدف پژوهش حاضر تعیین اثر دو شدت مختلف فعالیت بدنی بر سلو لهای اجدادی اندوتلیال سیار در زنان جوان سالم بود. به همین منظور به وسیله پرسشنامه، 15 دانشجوی دختر از بین داوطلبان شرکت در 22 سال، شاخص توده بدن ±1/ پژوهش به طور تصادفی انتخاب شدند و در دو گروه (گروه 1: میانگین سن 8 21 سال، شاخص توده بدن ±1/ 20/81±1/91 کیلوگرم بر متر مربع، تعداد 8 نفر، گروه 2: میانگین سن 5 20/38±1/66 کیلوگرم بر متر مربع، ...
سابقه و هدف: در طی جنین زایی ابتدائی، سیستم قلبی- عروقی یکی از اولین سیستم هایی است که تشکیل می شود. سلولهای بنیادی جنینی انسانی[1] (hESC) مدلی را به وجود می آورد که می توان از طریق آن مراحل تکاملی این سیستم را بررسی نمود. زمانی که این سلول ها از لایه مغذی خود جدا می شوند، hESC ها اجسام جنینی[2] (EB) را به وجود می آورند که پس از کشت، ناحیههایی از سلول های ضربان دار در 5/21% از EB ایجاد می شون...
