طراحی کنترل کننده به کمک الگوریتمهای تکاملی به منظور رسیدن به عملکرد مناسب upfcبا توجه به پیچیدگی ها و محدوده کاری گسترده ای که upfc باید در آن عمل کند استفاده از کنترل کننده های pi,pid با ضرایب ثابت در تمام نقاط کاری نمیتواند جوابگو باشد.بر این اساس طراحی یک کنترل کننده غیر خطی با استفاده از روشهای تکاملی مد نظر قرار گرفته است.
Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. the immune rejection of male semen in the female reproductive tract is explained as the failur...
conclusions these results exhibited the immuno potentiator effects of mip-3beta plasmid when coadministrated with the hcv core dna vaccine. complimentary studies integrating mip-3beta as a genetic adjuvant in hcv-core-dna vaccination models are warranted. results mice covaccinated with mip-3beta elicited an enhanced th1 biased systemic immune response as evidenced by higher ifn-γ/il-4 and anti-...
Introduction: The exact cause of most autoimmune diseases is still unknown; however, several factors play a role in causing or exacerbating autoimmune reactions. In addition to environmental factors such as bacterial, parasitic, fungal and viral infections, factors such as genetic characteristics and lifestyle are also included. Infections caused by viruses usually trigger a strong immune respo...
Background: Cationic immune stimulating complexes (PLUSCOMs) are particulate antigen delivery systems. PLUSCOMs consist of cationic immunostimulatory complexes (ISCOMs) derivatives and are able to elicit in vivo T cell responses against an antigen. Objective: To evaluate the effects of PLUSCOMs containing Leishmaniamajor antigens (SLA) on the type of immune response generated in the murine mod...
Background and Purpose: Gastroenteritis and the clinical profile caused by Microsporidia, an opportunistic pathogen, may be severe in immunocompromised individuals, especially in AIDS patients. Conventionally, it is necessary to detect the small infective spores in stained smears. However, due to the limitations of the microscopy-based methods, several DNA-based methods such as polymerase cha...
Body is exposed to oxidants and free radicals since birth. These compounds are highly reactive and react with different biomolecules. However living organisms possess an antioxidant system to face these compounds. Reactive oxygen species (ROS) in immune system cells, like other cells, are produced both as a part of the normal cell metabolism and during specific activities such as phagocytosis. ...
In recent years, the microbiome has been recognized as a key regulator of immune responses. Evidence suggests that changes in the microbiome can lead to chronic disease and even exacerbation of the disease. Impairment of innate immunity resulting from microbial incompatibility may worsen host susceptibility to infection and exacerbate chronic lung diseases. Specific microbes play a key role in ...
