OBJECTIVE To study the tissue pathology of breast lesions associated with hydrophilic polyacrylamide gel injection augmentation mammoplasty. DESIGN Retrospective study. SETTING Private anatomical pathology practice, Hong Kong. PATIENTS Eight patients who underwent lumpectomy of the breast due to complications of hydrophilic polyacrylamide gel injection for augmentation mammoplasty. MAIN...

The use of lyphogel to concentrate the number of virus particles in specimens for electron microscopic examination was studied in parallel with ultracentrifugation. One hundred faecal and urine samples were compared. Both methods had a similar sensitivity. Lyphogel was economical, simple, and rapid in use; in contrast to ultracentrifugation, it required relatively little material. The procedure...

Osteoarthritis is a chronic disorder characterized by joint cartilage degeneration with concomitant changes in the synovium and subchondral bone metabolism. Many conservative treatment modalities, one of which is intra-articular injections, have been described for the treatment of this disorder. Traditionally, hyaluranic acid and corticosteroids are the agents that have been used for this purpo...

Many diverse applications utilize hydrogels as carriers, sensors, and actuators, and these applications rely on the refined control of physical properties of the hydrogel, such as elastic modulus and degree of swelling. Often, hydrogel properties are interdependent; for example, when elastic modulus is increased, degree of swelling is decreased. Controlling these inverse dependencies remains a ...

BACKGROUND Increasing complications of polyacrylamide hydrogel (PAAG) augmentation mammoplasty, such as chronic persistent infection, have recently caught the attention of both the medical field and the general public. MATERIAL/METHODS A total of 96 patients with severe chronic infection following PAAG augmentation mammoplasty were treated in the present study including 63 cases with infectio...

Electroosmotic pumping through uncharged hydrogels can be achieved by embedding the polymer network with charged colloidal inclusions. Matos et al. [M.A. Matos, L.R. White, R.D. Tilton, J. Colloid Interface Sci. 300 (2006) 429-436], recently used the concept to enhance the diffusion-limited flux of uncharged molecules across polyacrylamide hydrogel membranes for the purpose of improving the per...

Amyloid-like protein nanofibers were assembled in vitro using a recombinant protein fusion, with yeast Sup35 and human SSB/La proteins as assembly units, where the length of the nanofibers was mostly between 100 and 400 nm. The protein nanofibers, hereafter referred to as Sup35-based protein nanofiber probes (SuPNPs), were used to sensitively detect anti-SSB/La antibodies [Sjögren's syndrome (S...

A novel approach was developed to prepare a superporous hydrogel with superior mechanical and elastic properties. According to this method, a synthetic monomer was polymerized and crosslinked in the presence of a water-soluble alginate polymer. Later in the process, the alginate part of the synthesized hydrogel was treated with metal cations, which resulted in a hydrogel hybrid with an interpen...

Abstract The adhesion strategies of the gecko's toe through surface adaptation spatulas to increase contact area and snail's epiphragm via dehydration‐induced solidification lock interfaces are combined design a class adhesion‐switchable hydrogels. hydrogels made incorporating CH 3 COONa·3H 2 O salt (SA) into polyacrylamide (PAM) aqueous networks construct supersaturated stimuli‐responsive phas...
