The in-situ lens-bound protein layer (LBPL) was characterized on hydrogels of varying water content and ionic-binding capacity. The LBPL proved to be critically dependent on the ionic binding capacity of a given hydrogel. On nonionic polymers the LBPL invariably was thin and largely insoluble. Histochemical staining allowed the detection of all major types of tear proteins. Amino acid analysis ...

Blocking immunoglobulin G (IgG) inhibits complement-mediated killing of serum-resistant Neisseria gonorrhoeae (GC) in immune human serum. We examined the mechanism of action of blocking IgG. Presensitization of GC with increasing concentrations of blocking IgG or F(ab')2 before incubation with bactericidal antibody and absorbed pooled normal human serum increased consumption and deposition of t...

Ionic liquids are a very important class of compounds due to their remarkable properties and wide range applications. On the other hand, capillary electrophoresis is also gaining importance in separation science because its fast speed inexpensive nature. The use ionic continuously. present review article describes applications electrophoresis. This general aspects electrophoresis, optimization ...

asphaltene precipitation and deposition is a serious problem in many iranian fields. the deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production. this paper studies the asphaltene problem and mitigation methods in wellstring systematically. it presents new approach based on the combination of thermodynamic modeling o...

the suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. a feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. physical vapor deposition (pvd) and pulsed plasma-enhanced chemical vapor deposition (pecvd), naturally, form asymmetric na...

In this paper the risk associated with deposition of aerosol (‘‘hygroscopic dust”) on printed circuit boards is assessed for different equipment designs and deployment. The amount of deposited dust is related to (1) the total dust availability in a given type of equipment and (2) to the rate of deposition of dust due to different mechanisms. Of these, the Brownian diffusion, gravitational settl...

Antibody to the polysaccharide capsule of type III group B streptococci (GBS) and complement are essential to host defense against systemic infection in neonates. Interactions between C3 degradation products and specific neutrophil receptors mediate the attachment and ingestion of these organisms. To evaluate the influence of capsule on C3 disposition, we compared the C3 fragments released from...

The challenge associated with the use of synovial fluid for osteoarthritic proteome studies is optimization step, which involves depletion high abundant proteins from samples. objective this study was to develop a cost efficient and effective method remove albumin canine studies. Pooled samples were obtained clinically healthy dogs (n=5), no radiographic features osteoarthritis. acetone precipi...
