background: micropatterning is becoming a powerful tool for studying cells in vitro. this method not only uses very small amount of material but also mimic the microenvironment structure present in living tissues better than flask culturing techniques. in previous studies using micropatterning of extracellular matrix proteins on glass surfaces, the rate of protein detachment from the surface wa...

oxidative and microbiological degradations are the main factors that determine the quality of food and the shelf life. color and moisture stability are important quality attributes that contribute to meat shelf life, salability and consumer acceptability. there is currently considerable interest in edible films coatings and natural antioxidants because of their potential to improve the quality ...

Group A streptococcal pyrogenic exotoxins A, B, and C (also known as scarlet fever toxins and erythrogenic toxins) were evaluated for relatedness to another streptococcus-derived lymphocyte mitogen, blastogen A. Streptococcal pyrogenic exotoxin A and blastogen A were immunologically cross-reactive and shared the same molecular weight, N-terminal amino acid sequence, and capacity to stimulate ra...

The case presented is of a patient with migratory polyarthritis and serological evidence of a recent streptococcal infection, consistent with the diagnosis of acute rheumatic fever, who in addition had multisystem disease manifestations. This case supports the concept that the sequelae of streptococcal infection can encompass a broader clinical spectrum than is suggested by the Jones criteria f...

M protein is a major surface component of group A streptococci, and more than 80 distinct serological types exist . Antigenic variability resides in the NH2-terminal distal portion ofthe fibrillarM protein molecule, whereas the COOH-terminal half is highly conserved among different M serotypes (1, 2) . With few exceptions, only serum IgGdirected to the antigenically variable portion ofM protein...

OBJECTIVE The recommended dosing frequency of oral penicillin for the treatment of acute streptococcal tonsillopharyngitis has long been 3 to 4 times daily. In 1994, treatment guidelines included twice-daily (BID) dosing for the first time, a recommendation that could significantly increase the ease of compliance. This meta-analysis was performed to determine whether overall cure rates differed...

BACKGROUND The incidence and severity of invasive group A streptococcal infection demonstrate great variability over time, which at least, in part, seems to be related to group A streptococcal type distribution among the human population. METHODS An enhanced surveillance study of invasive group A streptococcal infection (746 isolates) was performed in Sweden from April 2002 through December 2...

BACKGROUND People with a history of rheumatic fever (RF) are at high risk of recurrent attacks and of developing rheumatic heart disease following a streptococcal throat infection. Giving penicillin to these people can prevent recurrent attacks of RF and subsequent rheumatic heart disease. However, there is no agreement on the most effective method of giving penicillin. OBJECTIVES To assess t...
