Pettersson et a!. recently reported that prostate-specific antigen (PSA) corn-plexed to a1-antichymotrypsin (PSA-ACT) is unstable in aqueous solutions [1]. Recognizing the usefulness of PSA-ACT calibrators, given that most of the PSA in male serum is in the complexed form, they pointed out that establishment of optimal conditions for preparation and storage of PSA-AGT complexes to prevent disso...

Fewer than 15% of gastrointestinal stromal tumors (GIST) in pediatric patients harbor KIT or platelet-derived growth factor receptor A (PDGFRA) mutations in contrast to a mutation rate of 80% in adult GISTs. However, some therapeutic inhibitors of KIT have efficacy in pediatric GIST, suggesting that KIT may, nevertheless, play an important role in oncogenesis. In adult GIST, characteristic cyto...

AIM Quantitative evaluation of the effect caused by vaginal administration of gelatin capsules loaded with starch pellets and lyophilized powder, respectively, on vaginal pH and microflora. METHOD Administration of gelatin capsules loaded with fast-disintegrating starch pellets (group P) or lyophilized lactose/skimmed milk (group L) was compared to no intervention (group C) in a 3-way randomi...

Organisms were grown for periods varying from 20 to 48 hours in a peptone-yeast extract-glucose medium buffered at pH 6.8 to 7.0 with 0.05 Y phosphate buffer. Representative types which grew satisfactorily on this medium were selected for study. Cells were harvested by centrifugation and washed three times with water. The washed cells were suspended in a small volume of water, lyophilized, and ...

The legume group is an important source of lipids and fatty acids in animal and human nutrition. As a food source, the neuropharmacological and other potential therapeutic benefits of broad beans (Vicia faba, VF), an ancient plant in cultivation, have been documented. The objective of this study was to evaluate the chemical composition, physiochemical properties and the thermal stability of the...

BACKGROUND AND OBJECTIVE Successful root-coverage treatment depends on the thickness of the donor tissue. This study aimed to evaluate the thickness of donor tissue after augmentation of the connective tissue in the palatal area by implantation of lyophilized collagen sponge (Hemospon(®) ). MATERIAL AND METHODS Ten patients with an indication for root coverage, whose palate was deficient in a...
