The B1 (CD20) molecule is a Mr 33,000 phosphoprotein on the surface of human B lymphocytes that may serve a central role in the humoral immune response by regulating B-cell proliferation and differentiation. In this report, a cDNA clone that encodes the B1 molecule was isolated and the amino acid sequence of B1 was determined. B-cell-specific cDNA clones were selected from a human tonsillar cDN...
Transforming growth factor-b1 (TGF-b1), a multifunctional cytokine with fibrogenic properties, has been implicated in the pathogenesis of the vascular and target organ complications of hypertension. TGF-b1 may also regulate blood pressure via stimulation of endothelin-1 and/or renin secretion. Herein we explored the hypothesis that circulating levels of TGF-b1 protein (quantified using a TGF-b1...
The mitotic cyclins promote cell division by binding and activating cyclin-dependent kinases (CDKs). Each cyclin has a unique pattern of subcellular localization that plays a vital role in regulating cell division. During mitosis, cyclin B1 is known to localize to centrosomes, microtubules, and chromatin. To determine the mechanisms of cyclin B1 localization in M phase, we imaged full-length an...
We have examined the time course and patterns of covalent aflatoxin B1:DNA adducts produced within the ribosomal RNA gene sequences isolated from the liver nuclear DNA of aflatoxin B1-treated animals. Liver nuclear DNA was initially enriched in ribosomal DNA by cesium salt density centrifugation, and incubated under alkaline conditions to stabilize bound aflatoxin B1-DNA moieties. Alkali-treate...
Heterogeneous nuclear ribonucleoprotein (hnRNP) B1 is a RNAbinding protein of Mr 37,000. We previously reported that hnRNP B1 was specifically overexpressed in the nuclei of human lung cancer cells, particularly in squamous cell carcinoma (E. Sueoka et al., Cancer Res., 59: 1404 –1407, 1999). We extended this study to determine whether hnRNP B1 was overexpressed in roentgenographically occult c...
A brief review of the available experimental and theoretical results on production $\chi_{Q1}$ states in $e^+e^-$ annihilation photon-photon $\gamma\gamma^*$ interactions is presented. Future data $\chi_{c1}(1P)$, $\chi_{c1}(3872)$, $\chi_{c1} (4140)$, $\chi_{c1}(4274)$, $\chi_{c1}(4685)$, $\chi_{b1} (1P)$, $\chi_{b1}(2P )$, $\chi_{b1}(3P)$ resonances will help development unification predictio...
بررسی عملکرد لنفوسیتهای tcd8+ و سطح سایتوکاینهای il-2 , il-12 در یک وهله ورزش متوسط قبل از تزریق واکسن ویروس هرپس سیمپلکس تیپ یک پرداخته شده است.جامعه آماری 24موش نژاد بالبسی 6 تا 8 هفته که از مرکز پژوهش وتکثیر حیوانات آزمایشگاهی انستیتو پاستور تهیه و به مرکز پژوهش منتقل شد. و بصورت تصادفی دسته بندی شدند.موشها در سه گروه مختلف قرار گرفته و تزریق واکسن در گروههای تجربی کشت طحال جهت الایزای سایتو...
An improved monoclonal antibody immunoaffinity chromatography/high-pressure liquid chromatography/ fluorescence detection method was developed to measure aflatoxin (AF) exposure by quantifying AFM1 in human and rat urine samples. Analysis of different amounts of various AF metabolites showed that the immunoaffinity resin was highly selective for aflatoxin B1 (AFB1), AFB2, and AFM1. Recovery of ...
The individual and combined effects of dietary aflatoxin B(1 )(AFB(1)) and fumonisin B(1) (FB(1)) on liver pathology, serum levels of aspartate amino-transferase (AST) and plasma total protein (TP) of broilers were evaluated from 8 to 41 days of age. Dietary treatments included a 3 × 3 factorial arrangement with three levels of AFB(1 )(0, 50 and 200 μg AFB(1)/kg), and three levels of FB(1 )(0, ...
