fcεri, the high affinity receptor for ige plays a critical role in triggering the allergic reactions. it is responsible for inducing mast cell degranulation and deliberation of allergy mediators when it is aggregated by allergen and ige complexes. fcεri on the mast cells consists of three subunits; α chain directly binds ige, β chain and dimmer of γ chains together mediate intracellular signali...

In a prospective study, 232 neonates were examined sonographically using the methods of Graf and Terjesen. In order to determine the reproducibility of the methods, 50 hips were evaluated by two skilled examiners. In an inter-observer study, five physicians and five medical students evaluated 24 images, which were evaluated on ten occasions at two-weekly intervals by one of the authors. Statist...

A recently carried out unitarity based analysis [1, 2] involving the evaluation of Jarlskog’s rephasing invariant parameter J as well as the evaluation of the angles α, β and γ of the unitarity triangle is extended to include the effects of K − K̄ as well as B − B̄ mixings. The present analysis attempts to evaluate CP violating phase δ, |Vtd| and the angles α, β and γ by invoking the constraints ...

bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...

Plants belonging to the Weigela genus are traditionally used flourish gardens, homes, and other living areas. This contains ten species that mainly found in Asia, but many cultivars have been cultivated around world. Previous studies on some of this revealed occurrence triterpenoid saponins, which possess interesting biological activities such as cytotoxicity, anti-complementary activity, anti-...

In this paper, we study the properties of the generalized harmonic numbersHn,k,r(α, β). In particular, by means of the method of coefficients, generating functions and Riordan arrays, we establish some identities involving the numbers Hn,k,r(α, β), Cauchy numbers, generalized Stirling numbers, Genocchi numbers and higher order Bernoulli numbers. Furthermore, we obtain the asymptotic values of s...
