زمینه و هدف : گزارش های متناقضی در خصوص اثر الکل بر تشنجات صرعی وجود دارد. این مطالعه به منظور تعیین اثر اتانول بر میزان تغییرات عروق ریز مغزی به روش ایمونوهیستوشیمی در موش های سوری صرعی شده با پنتلین تترازول تحت درمان با والپریک اسید انجام شد. روش بررسی : در این مطالعه تجربی 36 سر موش سوری به طور تصادفی در گروه های 6 تایی تشنج (گروه اول): تزریق داخل صفاقی پنتلین تترازول (37 mg/kg) یک روز در می...
The programmed death-1 (PD-1) costimulatory pathway has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. We investigated the role of this pathway in establishing an immune privilege status of corneal allografts in mice. B7-H1, but not B7-DC or PD-1, was expressed constitutively in the eye, i.e., cornea, iris-ciliary body, and retina. After corneal...
در طول دهه گذشته علاقه زیادی به شیمی ایندازولها (بنزو [c] پیرازول،1و2-بنزودی آزول ) نشان داده شده است. این توجه بی شک به علت تنوع گسترده فعالیت های بیولوژیکی مشتقات ایندازول است، که باعث ترغیب دانشمندان برای سنتزهای جدید و بهینه کردن آنها و همچنین نشاندن گروههای عاملی مختلف روی سیستم حلقه ایندازولی شده است. در این پایان نامه، سنتز 3- هیدروکسی-1h-ایندازولها با استفاده از واکنش ماده اولیه آنترا...
Applying the methods developed in [3], in [4] we have constructed generalized CS attached to the Jacobi group G1 = H1 oSU(1, 1), based on the homogeneous Kähler manifold D 1 = H1/R × SU(1, 1)/U(1) = C 1 × D1. Here D1 denotes the unit disk D1 = {w ∈ C ; |w| < 1}, and Hn is the (2n + 1)-dimensional real Heisenberg-Weyl group with Lie algebra hn. In [4] we have also emphasized that, when expressed...
We have reported previously that the serum nm23-H1 level is a prognostic factor for non-Hodgkin's lymphoma. In this study, we examined nm23-H1 expression in T- and natural killer (NK)-cell lymphoma in order to evaluate whether lymphoma cells produce the protein. The clinical significance of the cytotoxic molecules, T-cell intracellular antigen-1 (TIA-1) and granzyme B and nm23-H1 expression wer...
In this work, the grafting of maleic anhydride onto two types of linear low density polyethylene with hexene-1 comonomer (LLDPE-H1) and butene-1 comonomer (LLDPE-B1), in the presence of styrene monomer (St) and dicumyl peroxide initiator (DCP) has been studied. The combined influences of MAH, St and DCP on the grafting efficiency via a melt reactive mixing process have been investigated using r...
Purpose: We examined whether nm23-H1 is a prognostic factor of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Experimental Design: We studied 102 consecutive, untreated PTCL-NOS patients from 1998 to 2008. The expression of nm23-H1 and TIA-1 was studied by immunohistochemistry. Results: nm23-H1 was positive in 44.1% and TIA-1 in 78.4% of the PTCL-NOS patients. nm23-H1 expressio...

We present a new expression of the polynomial Hamiltonian of the Garnier system in two variables. 1. Main results The Garnier system in two variables is equivalent to the rational Hamiltonian system given by (see [18], cf. [3]) dq1 = ∂H1 ∂p1 dt + ∂H2 ∂p1 ds, dp1 = − ∂H1 ∂q1 dt− ∂H2 ∂q1 ds, dq2 = ∂H1 ∂p2 dt + ∂H2 ∂p2 ds, dp2 = − ∂H1 ∂q2 dt− ∂H2 ∂q2 ds, H1 = − q1(q1 − 1)(q1 − t)(q1 − s)(q2 − t) (...
B7-H1 is a recently identified B7 family member that, along with one of its receptors, programmed death-1 (PD-1), has been involved in multiple immunopathologic scenarios. However, the nature of B7-H1 and PD-1 in human hepatocellular carcinoma (HCC) remains poorly defined. We investigated the expression and functional relevance of this pathway in patients with HCC. We showed that B7-H1 expressi...
