objective(s): despite treatment with antibiotics and vaccination with bcg, tuberculosis (tb) is still considered as one of the most important public health problems in the world. therefore, designing and producing a more effective vaccine against tb seems urgently. in this study, immunogenicity of a fusion protein which consisting or comprising cfp-10 from mycobacterium tuberculosis and the fc-...

the dual diene/1,3-dipolar character of 1-h-imidazole 3-oxide, hio 1, allows this compound toparticipate in a competitive diels-alder (da)/1,3-dipolar cycloaddition (13dc) reaction toward c=sdouble bond of the electro-deficient sulfonyl methane sfm 2. the b3lyp/6-311++g(d,p) calculatedrelative gibbs free energies indicate that among the studied 13dc and da reactions, former iscompletely preferr...

abstract-a novel and efficient method has been developed for the synthesis of pyrano[3,2-c]quinoline-2,5-dione derivatives by the convenient ultrasound-mediated condensation of 4-hydroxyquinolin-2-one with meldrum’s acid and aldehydes in the presence of a catalytic amount of [hmim]hso4 as a green, efficient and reusable acidic ionic liquid medium. the stability of the ionic liquid during the re...

In 1996, Dontchev [14] introduced and investigated a new notion of non-continuity called contra-continuity. Recently, Baker et al. [6] offered a new generalization of contra-continuous functions via λ-closed sets, called almost contra λ-continuous functions. It is the objective of this paper to further study some more properties of such functions.

In this paper, we define a new concept, called N -group soft intersection action (SI) on a soft set. This new notion gathers soft set theory, set theory and N -group theory together and it shows how a soft set effects on an N -group structure in the mean of intersection and inclusion of sets. We then obtain its basic properties with illustrative examples and derive some analog of classical N -g...

introduction: cardiac preconditioning represents the most potent and consistently reproducible method of rescuing heart tissue from undergoing irreversible ischemic damage. the aim of the present study was to evaluate oxytocin (ot) induced cardioprotection and its signaling pathways on lactate dehydrogenase (ldh) and creatine kinase-mb isoenzyme (ck-mb) in the anesthetized rats. methods: eighty...

two simple protocols for the synthesis of three-component condensation reaction of an aldehyde, β-ketoester and urea or thiourea to obtain the 3, 4-dihydropyrimidin-2(1h)-ones (thiones) using nano silica phosphoric acid are reported. short reaction times, high yields, reusability of catalyst and easy workup are some advantages of these protocols.

In this paper, we investigate the global behavior of the difference equation of order three xn+1 = α+ xn−2 xn , n = 0, 1, . . . where the parameters α, k ∈ (0,∞) and the initial values x−2, x−1 and x0 are arbitrary positive real numbers.

We show that there are ordinary differential equations in R with unbounded solutions, for which the difference equations obtained by using the forward Euler method have all solutions bounded.
