The clinical and molecular findings in an infant with mild manifestations of cystic fibrosis, who is homozygous for the G542X mutation, and her heterozygous nephew, who is severely affected, are described. The major mutation recently identified in the CFTR genel-3 is a specific deletion of three base pairs, which results in the loss of a phenylalanine residue at amino acid position 508 (AF508)....
در این تحقیق روشی برای سنتز پیریمیدین¬های پر استخلاف با استفاده از واکنش دی فنیل استو نیتریل با دی الکیل استیلن دی کربوکسیلات درحضور تری فنیل فسفین ارائه گردید. همانطور که مشاهده شد محصول واکنش با راندمان نسبتا بالایی و بدون نیاز به استفاده از ستون کروماتوگرافی استخراج شد
In cystic fibrosis (CF) patients, chronic airway infection by Pseudomonas leads to progressive lung destruction ultimately requiring lung transplantation (LT). Following LT, CF-adapted Pseudomonas strains, potentially originating from the sinuses, may seed the allograft leading to infections and reduced allograft survival. We investigated whether CF-adapted Pseudomonas populations invade the do...

Chronic bacterial airway infections are the major cause of mortality in cystic fibrosis (CF). Normal airway defenses include reflex stimulation of submucosal gland mucus secretion by sensory neurons that release substance P (SubP). CFTR is an anion channel involved in fluid secretion and mutated in CF; the role of CFTR in secretions stimulated by SubP is unknown. We used optical methods to meas...
Fractional exhaled nitric oxide (F(eNO)) has been reported to be reduced in cystic fibrosis (CF) patients. However, data from young children are conflicting and it is not clear whether this is a primary feature of the disease or a secondary response. The present study compared F(eNO) between CF and healthy infants using a validated single-breath technique. A total of 23 healthy infants (11 fema...
قارچSclerotinia sclerotiorum یکی از مهمترین عوامل بیماری‌زای گیاهی با دامنه میزبانی وسیع می‌باشد. به منظور ردیابی مایکوویروس‌های آلوده‌کننده، جدایه Cea این قارچ از هرباریوم دانشگاه تهران تهیه گردید. جداسازی آر ان ای دولای از میسلیوم‌های لیوفلیزه‌شده با استفاده از ستون کروماتوگرافی همراه با سلولزCF-11 انجام شد. در نهایت یک قطعه نوکلئیک اسید به اندازه 5/2 کیلو‌باز از این جدایه استخراج گ...
OBJECTIVE To examine the possible effects of maternal and fetal characteristics on the fetal fraction in maternal plasma cell-free (cf) DNA at 11-13 weeks' gestation and estimate the proportion of pregnancies at high risk of non-invasive prenatal testing (NIPT) failure because the fetal fraction is less than 4%. METHODS In 1949 singleton pregnancies at 11-13 weeks' gestation cf-DNA was extrac...
Objective: To observe the gains in bone mass in children and adolescents with cystic fibrosis (CF) over 24 months and examine the relationship between areal bone mineral density (aBMD) and associated clinical parameters including physical activity, nutrition and 25-hydroxyvitamin D (25OHD). Methods: Areal BMD of the total body (TB), lumbar spine (LS) and total femoral neck (FNt) were repeatedly...
Sex differences in thoracic adaptation have been reported in patients with cystic fibrosis (CF). The interplay between the pattern of thoracic adaptation and the function of the respiratory muscles in male and female CF patients with pulmonary hyperinflation was investigated. Thoracic dimensions and diaphragm length were measured at residual volume, functional residual capacity and total lung c...
