background: salmonella is one of the causes of food-borne illnesses worldwide resulting in a wide range of human diseases. the aim of this research was to study molecular epidemiology and antimicrobial resistance of salmonella spp. isolated from resident patients in mazandaran province, northern iran. methods: totally, 51 stool samples were collected from patients in 20 outbreaks recorded in he...

background: to use different methods for serodiagnosis of ruminants' haemonchosis is important because detection of egg in the faeces is not so reliable. methods: peptide bands of 5 different crude antigens of intestine, uterus, cuticle, whole male and whole female of hae­monchus contortus were determined using sds-page and western blotting. five lambs were infected with 10,000 third stage larv...

The sample involved 72 Elective Chemistry students level 200, whose other major su...

Nitrogen is one of the most prominent hetero atoms found in heterocycles. The corresponding electron lone pairs of these nitrogen atoms are mainly responsible for properties like the basicity and the pkb-values of the investigated heterocycle. Nevertheless, the overall electronic state of a molecule is also directly related to observable physico-chemical properties. This fact underlines a possi...

Brinker is the key target protein of the Drosophila Decapentaplegic morphogen signalling pathway. Brinker is widely expressed and can bind with DNA. NMR spectra suggest that apo-Brinker is intrinsically unstructured and undergoes a folding transition upon DNA-binding. However, the coupled mechanism of binding and folding is poorly understood. Here, we performed molecular dynamics (MD) simulatio...

Understanding the structural and energetic requirements of non-fibrillar oligomer formation harbors the potential to decipher an important yet still elusive part of amyloidogenic peptide and protein aggregation. Low-molecular-weight oligomers are described to be transient and polymorphic intermediates in the nucleated self-assembly process to highly ordered amyloid fibers and were additionally ...

Peanut allergy is a life-threatening, IgE-mediated allergic disease. In developed countries, the prevalence rate of peanut allergy in school-aged children is reported to be in excess of 1% and continues to rise, representing a major public health concern. Peanut allergy is diagnosed on the basis of a relevant clinical history combined with results of skin-prick testing and/or peanut-specific Ig...
