Background and Aims: The protozoan parasites of the genus Leishmania are the causative agents of various clinical diseases. Different methods of cultivation of Leishmania parasites are available. In the present study, the efficacy of the LB broth with rabbit lyophilized anti-sheep red blood cell haemolysin was evaluated in the cultivation of promastigotes of Leishmania major. Materials and Met...

aflatoxin m1 (afm1) is an important mycotoxin frequently found in milk and dairy products. dairy products and colostrum may be contaminated by aflatoxin m1 when dairy cattle have fed with aflatoxin b1-contaminated feeds. this study was undertaken in a dairy farm around tehran province to determine the presence and level of aflatoxin m1 (afm1) in spray dried and lyophilized colostrum samples. in...

BACKGROUND Anemia associated with chronic kidney disease (CKD) often requires treatment with recombinant human erythropoietin (EPO). This study investigated the therapeutic equivalence between lyophilized powder and standard liquid EPO alfa by subcutaneous (SC) administration in hemoglobin maintenance among patients on hemodialysis. METHODS This was a single-blinded, randomized, controlled, s...

Staphylococcus aureus bacteriophages (25 phages) were lyophilized in aliquots 12 to 18 years ago and stored in vacuo at -20 degrees C. Eight viruses each lost one log titer, while seventeen retained the original titers. The use of lyophilized phages provided more reproducible phage typing and reduced by 75% the complexity and cost. This important test is thus made feasible for more laboratories.

introduction: neurotensin (nt) is a tridecapeptide that binds specifically to neurotensin receptors. several forms of cancer, including small cell lung cancer, colon, pancreatic and prostate carcinomas especially exocrine pancreatic carcinomas express receptors for neurotensin peptide. radiolabeled neurotensin derivatives with a high affinity for these receptors might be used for scintigraphy. ...
