listeria monocytogenes can cause serious infection and recently, relapse of listeriosis has been reported in leukemia and colorectal cancer, and the patients with klebsiella pneumoniae are at increased risk of colorectal cancer. translation initiation codon recognition is basically mediated by shine-dalgarno (sd) and the anti-sd sequences at the small ribosomal rna (ssu rrna). in this research,...

saffron is one of the highly exotic spices known for traditional values and antiquity. it is used for home décor besides serving as a colorant flavor and is widely known for medicinal value. over the last few years, saffron has garnered a lot of interest due to its anti-cancer, anti-mutagenic, anti-oxidant and immunomodulatory properties. integration of systems biology approaches with wide appl...

an investigation was carried out to study the developmental time, reproduction and life table of three populations of the onion thrips, thrips tabaci lindeman, on onion (khorasan and golestan populations) and also on tobacco (mazandaran population) in the laboratory at 25â°c, 50% rh and 16: 8 h l: d. the total life cycle from egg to adult of khorasan, golestan and mazandaran populations were ga...

abstract background: with respect to the difference in the interaction of thermal neutron and x rays with matter, using two radiography systems of thermal neutron and x rays will yield highly valuable information for studying the inner structure of biologic samples. methods: the high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool i...

چکیده بر اساس مطالعات انجام شده در فصول زراعی 1386 و 1387، بعضی از جنبه های زیستی کرم ساقه خوار برنج (chilo suppressalis walker) شامل تعداد سنین لاروی و طول دوره ی رشد و نمو مراحل مختلف زیستی در دو نسل در منطقه ی مازندران بررسی شد. نتایج پژوهش حاضر نشان داد که تعداد سنین لاروی کرم ساقه خوار برنج در نسل های اول و دوم متفاوت می باشد، به طوری که این حشره در نسل اول دارای 6 و در نسل دوم دارای 5 سن ...

The bio-ontologies and phenotypes special issue includes eight papers selected from the 11 papers presented at the Bio-Ontologies SIG (Special Interest Group) and the Phenotype Day at ISMB (Intelligent Systems for Molecular Biology) conference in Boston in 2014. The selected papers span a wide range of topics including the automated re-use and update of ontologies, quality assessment of ontolog...

Diffuse malignant peritoneal mesothelioma (DMPM) is an uncommon and locally aggressive tumor with poor prognosis. Currently, no standard therapy is available. The biology of this disease is still poorly understood. We performed a systematic search of relevant studies on clinical management and biological research of DMPM. Trials were selected using a predetermined protocol. The current evidence...

Text mining has an important role to play in aiding experts to construct domain specific ontologies by highlighting the important classes, properties and relations that occur within large text collections. In this paper we propose a systematic framework for discovery of ontological types using typing information complemented with statistical filtering. Preliminary experiments are conducted on t...
