Uptake of Particulate Antigens in a Nonmammalian Lung: Phenotypic and Functional Characterization of Avian Respiratory Phagocytes Using Bacterial or Viral Antigens

Respiratory Phagocytes Using Bacterial or Functional Characterization of Avian Nonmammalian Lung: Phenotypic and Uptake of Particulate Antigens in a Vervelde

Uptake of particulate antigens in a nonmammalian lung: phenotypic and functional characterization of avian respiratory phagocytes using bacterial or viral antigens.

Major distinctive features of avian lungs are the absence of draining lymph nodes and alveoli and alveolar macrophages (MPhs). However, a large network of MPhs and dendritic cells (DCs) is present in the mucosa of the larger airways and in the linings of the parabronchi. For the modulation of respiratory tract immune responses, for example, by vaccination, a better understanding of Ag uptake in...

Identification of bacterial antigens and super antigens in synovial fluid of patients with arthritis: a cross sectional study

  Background : An accurate and prompt diagnosis of bacterial arthritis is essential for earlier treatment and a good outcome. Superantigens produced by Staph. Aureus are among the most lethal toxins. The paper objective was Identification of common bacterial antigens and S.aureus superantigens in synovial fluid (SF) of children with negative culture and direct smear for other bacteria except fo...

HSP Roles as Biomarkers and Antigens in Bacterial and Viral Infections

Diagnosis of infectious diseases remains an important issue in medical science. Identification of biomarkers can be used to predict early infections. Recently, heat shock proteins (HSPs) have been known as the conserved compounds expressed under stress conditions in both prokaryotic and eukaryotic systems. These proteins act as molecular chaperones. Several studies showed the increased levels o...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
