the protective capacity of the crude extracts from larval and nymphal stages of hyalomma anatolicum anatolicum was examined in the new zealand white rabbits. the rabbits were randomly divided into 3 groups of five animals. the rabbits in groups 1 and 2 were immunized with crude extracts of larval and nymphal antigens, respectively and group 3 was served as control. following challenge of each r...
چکیده سابقه و هدف: کادمیوم یک فلز سنگین است که اثر مخرب زیادی بر کیفیت محصول دارد. افزون بر آن‌یک فلز بسیار متحرک در خاک و محیط‌زیست می‌باشد و گیاهان می‌توانند به آسانی کادمیوم را جذب و آن را به بخش‌های هوایی خود منتقل کنند. با توجه به افزایش مناطق آلوده در کشور و وجود زمین‌های کشاورزی زیر کشت گیاهان علوفه‌ای مختلف و مصرف این محصولات علوفه‌ای در بخش دام موجب شد تا این پژوهش با هدف بررسی ت...
the features of helicobacter pylori adhesins, their interactions with their host counterparts, regulated and selective gene expressions are amongst the many clever strategies this microorganism undertakes to survive the otherwise sterile gastric milieu. the ingenious crafting of these interactions and the respective host reactions govern, in part, an array of consequences ranging from asymptoma...
patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...
Abstract BACKGROUND: Diagnosis of Echinococcus granulosus in the definitive host particularly in dog is the significant complication in the endemic area. OBJECTIVES: The aim of this study is serological detection of E. granulosus in the infected dogs. METHODS: Dot-ELISA based on the copro-antigen and recombinant EPC1 antigen (rEPC1) for antibody detection was performed. Blood and fecal samples ...
Semaphorin 4D (SEMA4D, CD100) and its receptor plexin-B1 (PLXNB1) are broadly expressed in murine and human tumors, and their expression has been shown to correlate with invasive disease in several human tumors. SEMA4D normally functions to regulate the motility and differentiation of multiple cell types, including those of the immune, vascular, and nervous systems. In the setting of cancer, SE...
Background Immune suppression is one of the hallmarks by which head and neck squamous cell carcinoma (HNSCC) develops a tumor permissible environment[1]. Semaphorin 4D (Sema4D), known for its various developmental, physiological and pathological effects, was recently shown to play a role in regulating the immune system[2]. Sema4D is expressed in many epithelial tumors including HNSCC[3]; yet, t...
