introduction: angiogenesis, the process of new blood vessel formation from pre-existing vessels, has important physiological roles in embryonic development, female reproduction cycle, and wound healing. it is also crucial for pathological processes in several diseases especially tumor growth and metastasis. thereby, inhibition of angiogenesis as an addition to the conventional therapies such as...

a highly efficient cloning vector was constructed for cloning pcr products by inserting an 80 bp dna fragment into pgem-5zf (+) vector. the xcm i digestion of this vector gave rise to a 3’ overhanging deoxythymidine offering the possibility of cloning pcr products with 3' adenosine overhang created by taq dna polymerase. furthermore, two ecor i sites were added to the construct for identificati...

conclusions results of this study did not support the hypothesis that dairy products consumption protects against mets and its components. patients and methods in this cross-sectional study, 785 adolescent aged 10 to 19 years, participated from the fourth phase of the tehran lipid and glucose study. usual dietary intake was assessed using a valid semi quantitative food frequency questionnaire. ...

background: polycystic ovary syndrome (pcos) is the most common endocrine disorder in reproductive women. nearly 10% of young women in this period involved. although factors such as insulin resistance, hyper insulinemia, obesity and dietary are suggested to be associated with pcos, cause of pcos is not completely understood. dairy products (a key component of the usual diet) of participants can...

aflatoxin m1 (afm1), a carcinogenic substance is found in milk and dairy products. the effect of season and type of dairy products on afmi level in northern iran was investigated in this study.three hundred samples (each season 75 samples) including raw and pasteurized milk, yoghurt, cheese, and cream samples were collected from three distinct milk producing farms. the samples were subjected to...

Given a labeling c of the edges of a directed graph E by elements of a discrete group G, one can form a skew-product graph E ×c G. We show, using the universal properties of the various constructions involved, that there is a coaction δ of G on C∗(E) such that C∗(E ×c G) is isomorphic to the crossed product C ∗(E) ×δ G. This isomorphism is equivariant for the dual action δ̂ and a natural action ...

In this note we discuss the structure of systems of coupled cells (which we view as systems of ordinary differential equations) where symmetries of the system are obtained through the group G of global permutations of the cells and the group L of local internal symmetries of the dynamics in each cell. We show that even when the cells are assumed to be identical with identical coupling, the way ...

Recently, the quality and safety of organic products is the topic of prime concern. While this demand increases since consumer considers organic products are healthier and harmless than conventional products. In the country like India, organic agricultural is not novel and are effectively performs in varied climates such as tribal mountains, mountainous areas and rain-fed zones of the country. ...

Objective: Malaria is an infectious disease commonplace in tropical countries. For many years, major antimalarial drugs consisted of natural products, but since 1930s these drugs have been largely replaced with a series of synthetic drugs. This article tries to briefly indicate that some plants which previously were used to treat malaria, as a result of deficiencies of synthetic drugs, have rev...
