Here we report that grafting of a short antimicrobial peptide, anoplin, to chitosan polymers is a strategy for abolishing the hemolytic propensity, and at the same time increasing the activity of the parent peptide. Anoplin-chitosan conjugates were synthesized by CuAAC reaction of multiple peptides through 2-azidoacetyl groups on chitosan.
PCH is a rare autoimmune hemolytic anemia (AIHA) but is one of the most common causes of AIAH in children. For the diagnosis, it is important to perform the appropriate methods of serological investigation and show the typical biphasic reaction. This is a case report of a child who presented with features of haemolysis and was diagnosed with PCH of this way.
Abstract Background and Objective: Snake venom is a complex of several toxic elements and enzymes. It has the agents with the ability to destroy cellular and subcellular membrane and to bring about hemolysis of red blood cells (RBC). Two types of direct and indirect hemolytic activity are known in snake venom in that phospholipase A2 is responsible for the indirect lysis. The aim of this st...
1. The hemolytic variety of streptococcus is homogeneous, consisting of members that are nearly identical. 2. This homogeneity is most strikingly displayed in the behavior of these streptococci in the complement fixation reaction, all the strains studied reacting in a nearly identical way with all the antisera.
A method is described for rapidly obtaining fresh extracts of microorganisms by percussion of the frozen cells. Filtrates giving the biuret reaction and yielding heavy precipitates upon the addition of acetic acid were obtained from the washed cells of cultures of yeast, hemolytic streptococcus, pneumococcus, B. coli, B. xerosis, B. dyphtheriae and the bacillus of bovine tuberculosis.
