Modulation and suppression of the host immune response by nematode parasites have been reported extensively and the cysteine protease inhibitor (cystatin) is identified as one of the major immunomodulator. In the present study, we cloned and produced recombinant cystatin protein from nematode parasite Haemonchus contortus (rHCcyst-2) and investigated its immunomodulatory effects on goat monocyt...

resection is the most common treatment choice for sigmoid volvulus, a common complication in our region. a new minimally invasive technique for sigmoid resection with local anesthesia was done in this study. this method is invented to avoid general on regional anesthesia in high-risk patients. nineteen patients were evaluated and then 14 were enrolled in this study. sigmoidectomy with a left lo...

the meshless local radial point interpolation (mlrpi) method is applied to examine the magnetohydrodynamic (mhd) ow of third grade uid in a porous medium. the uid saturates the porous space between the two boundaries. several limiting cases of fundamental ows can be obtained as the special cases of present analysis. the variations of pertinent parameters are addressed.

let ( r,m ) be a noetherian local ring, a an ideal of r and m a finitely generated r- module. we investigate some properties of formal local cohomology modules with respect to a serre subcategory. we provide a common language to indicate some properties of formal local cohomology modules. let ( r,m ) be a noetherian local ring, a an ideal of r and m a finitely generated r- module. we investigat...

In many cases economic optimal operation is the same as maximum plant throughput, which is the same as maximum flow through the bottleneck(s). This insight may greatly simplify implementation. In this paper, we consider the case where the bottlenecks may move, with parallel flows that give rise to multiple bottlenecks and with crossover flows as extra degrees of freedom. With the assumption tha...

in this paper, we apply the local fractional adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of fredholm integral equations of the second kind within local fractional derivative operators. the iteration procedure is based on local fractional derivative. the obtained results reveal that the proposed methods are very efficient and simple tools ...

poultry products are considered as one of the most important sources of food for humans, worldwide. indigenous poultry production has grown in popularity among villagers and some urbanites due to simple maintenance conditions, adequate adaption of poultry to different climatic conditions, and acceptable product yield. parasites are among the main pathogenic agents, threatening the health of pou...

Streptococcus iniae is a Gram-positive bacterium and a severe pathogen to a wide range of economically important fish species. In addition, S. iniae is also a zoonotic pathogen and can cause serious infections in humans. In this study, we identified from a pathogenic S. iniae strain a putative bacteriocin, Sil, and examined its biological activity. Sil is composed of 101 amino acid residues and...

Transforming growthfactor (TGF)-,8 has several downregulatoryfunctions on the immune systenm inhibition ofinterleukin-2 receptor induction, decrease of interferon-yinduced class II antigen expression, inhibition of macrophage activation, as weUl as cytotoxic and lymphokineactivated kilter cell generation. TGF-(8 has also been recognized as an important immunoregulator in murine leishmaniasis, f...

Ly49B is a potentially important immunoregulator expressed on mouse myeloid cells, and it is thus an unusual member of the wider Ly49 family whose members are ordinarily found on NK cells. Ly49B displays substantial sequence divergence from other Ly49s and in particular shares virtually no amino acid sequence identity with the residues that have been reported to bind to MHC class I (cI) ligands...
