A revised Marko-Siggia elastic model for DNA double helix [Macromolecules 27, 981 (1994)] is proposed, which includes the WLC bending energy and a new chiral twisting energy term. It is predicted that the mean helical repeat length (HRL) for short DNA rings increases with the decreasing of chain length; while for very long chains, their mean HRL is the same, independent of both the chain length...

Introduction. Nowadays, Hexvix (hexyl aminolevulinate HAL) fluorescence cystoscopy represents an increasingly acknowledged diagnostic method for patients with bladder cancer. The aim of our study was to establish the place of this procedure in superficial bladder tumors diagnosis, and to compare it with standard white light cystoscopy (WLC). Material and methods. In December 2007, Hexvix fluore...

Methods Patients with stage 0-III disease were recruited prior to XRT (baseline) and randomized to one of three groups: Yoga (YG-n=53) or Stretching program (STR-n=56) 3 times a week for 6 weeks during XRT or Waitlist Control (WLC-n=54). Self-report measures of fatigue (BFI), depression (CESD), QOL (SF-36), benefit finding (BF), and spirituality (FACT-SP) were completed and saliva collected at ...

The present study examined the effectiveness of a transdiagnostic prevention programme, Super Skills for Life (SSL), among children and adolescents with emotional problems in residential care institutions (RCIs) low- middle-income country Mauritius using randomised waitlist-controlled trial (RCT). SSL is based on principles cognitive behavioural therapy, activation, social skills training, uses...

The DNA contained in every living cell not only stores the genetic information; it functions in a complex molecular network that can condense, transcribe, replicate and repair genes. The essential role played by the sequence dependent structure and deformability of DNA in these basic processes of life, has received increasing attention over the past years. The present work aims at better unders...

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Persons with posttraumatic stress disorder (PTSD) have been shown to display elevated baseline cardiovascular activity and a heightened physiological reactivity to trauma-related stimuli. Study 1 examined differences in baseline heart rate (HR) and HR reactivity in 68 survivors of motor vehicle accidents (MVAs) and healthy controls without MVA. MVA survivors with PTSD (n=26), subsyndromal PTSD ...

BACKGROUND Systematic violence is a long-standing problem in Iraq. Research indicates that survivors often experience multiple mental health problems, and that there is a need for more rigorous research that targets symptoms beyond post-traumatic stress (PTS). Our objective was to test the effectiveness of two counseling therapies in Southern Iraq in addressing multiple mental health problems a...

We have described three RNases in wheat leaves (Triticum aestlvum L. cv Chinese Spring) and developed assays for measuring each RNase individually in crude leaf extracts. We initially used activity staining in sodium dodecyl sulfate-polyacrylamide gels to characterize RNases in extracts of primary and flag leaves. We thus identified acid RNase (EC 3.1.27.1, here designated RNase WLA), and two a...
