Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...

cantaloupe (cucumis melo) volume was measured using water displacement and image processing methods. the volume determined from image processing method was compared to the volume determined by the water displacement method using the paired samples t-test and the bland-altman approach. the paired samples t-test results showed that the volume determined by image processing method was not signific...
Salmonelosis is a disease caused by the Salmonella sp. that causes decrease in CD4+ expression. Black grape can boost immune system through CD4+/CD8+ proliferation. The purpose of this study was to evaluate activity black extract and CD8+ expression mice infected with typhimurium. Research method grapes, typhimurium 108 infection, bacterial evaluation, therapy, flowcytometery examination, 95% A...
abstract background and objective: hirudin is an anticoagulant polypeptide secreted from the salivary glands of leeches. recombinant hirudin is a strong anticoagulant agent in arterial and venous thrombosis. the aim of this study was to evaluate the effect of inserting protein a signal peptide sequence of pezz18 plasmid on expression and secretion of the recombinant hirudin in e.coli. ...
Background and Aim: Regarding to various problems in the activation of dendritic cells and immune system’s responses, finding of a safe, effective and applicable agent is highly desirable. Chitosan is an effective gene delivery agent and also a part of nanoscaffolds. In the present study,chitosan nanopolymers effect on dendritic immune cells were assessed. Materials and Methods: In this experim...
the objective of this research was to develop a suitable method for color sorting of fruits. accordingly, a color-sorting system was designed and a prototype developed and then tested. this system includes an optic head which is designed to develop a reflection of the fruit. output of the head is then processed in an electronic control system which generates the appropriate signal for ejection ...
sorting and classification of agricultural products by machine vision system reduce costs and increase quality and accuracy. this research was performed to develop an algorithm and machine vision system for separating dirty and defects eggs and classifying by volume and weight. this machine installed on transport line egg in agriculture included a digital camera, computer and mechanical device ...
there are instances in which it is desirable to determine relationships among fruit physical attributes. for example, fruits are often graded on the basis of size and projected area, but it may be more suitable and/or economical to develop a machine which grades by mass. therefore, a relationship between mass and dimensions or projected areas and/ or volume of fruits is needed. various grad...
