Wound healing and repair are the most complex biological processes that occur in human life. After injury, multiple biological pathways become activated. Impaired wound healing, which occurs in diabetic patients for example, can lead to severe unfavorable outcomes such as amputation. There is, therefore, an increasing impetus to develop novel agents that promote wound repair. The testing of the...

a purification procedure of pertussis toxin (pt) from submerged culture of bordetella pertussis (b.pertussis) strain 134 using adsorption and affinity chromatography was discussed. the yield of the resulting pt was approximately 37.5mg/l of concentrated culture supernatant. the polypeptide pattern of the purified pt was investigated by sds-page and showed five bands between 11 to 26 kda using l...

background and objectives: brucellosis is an important health problem in developing countries and no vaccine is available for the prevention of infection in humans. because of clinically infectious diseases and their economic consequences in human and animals, designing a proper vaccine against brucella is desirable. in this study, we evaluated the immune responses induced by a designed recombi...

background: the incidence of allergic and asthmatic diseases has been continuously increased in both industrial and developing countries. extracts from various known allergens are used for the diagnostic and therapeutic purposes. objective: to investigate the effects of an extract prepared from chenopodium album (ch.a.) pollen to induce allergic asthma in balb/c mice. methods: balb/c mice were ...

antigenicity of proteins found in cow's milk is age dependent. this is primarily due to infants possessing a more permeable intestinal wall than that in adults. thus infants may acquire cow's milk allergy during their first year of life. while milk antigen specific ige may cause allergy in susceptible subjects, there is some evidence indicating that milk antigen specific igg may play some role ...

Silver salts and nanosilver (NS) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. Therefore, in this study, the possible dermal toxicity of NS particles and silver nitrate (AgNO3), was tested by determining the serum level of transforming growth factor-β1(TGF-β1) and study on of mouse skin tissue. In this stu...

A lipid named DCPA was synthesized under microwave-assisted heating. possesses a pyridine betaine, hydrophilic group that can be complexed with water through hydrogen bonding (DCPA-H2O). DCPA-H2O liposomes became protonated relatively fast already at pH<6.8, due to the high HOMO binding energy of DCPA-H2O. In murine models, had longer blood circulation times than natural DPPC or cationic DCPM l...
