While structurally complex benthic egg capsules can lower the vulnerability of gastropod embryos to a variety of environmental risks, including predation, desiccation, osmotic shock, and bacterial attack, little is known about their ability to shield embryos from ultraviolet radiation (UV) I examined the exposure of benthic egg capsules of the marine intertidal gastropod Nucella emarginata to s...

Hollow permeable polysiloxane capsules with diameters between 180 and 210 nm were firstly fabricated by consecutively cocondensed methyltrimethoxysilane and dimethyldimethoxysilane monomers onto polydimethylsiloxane and subsequently removing the templated polydimethylsiloxane by exposure to solvents. The morphology of the polymer particles was demonstrated by transmission electron micrographs (...

Presently used single-needle air-driven droplet generators are incapable of producing sufficient numbers of islet-containing droplets in a sufficiently short time-period to allow for successfully grafting alginate-poly-L-lysine encapsulated islets in large animals or humans. We have designed an air-driven multineedle droplet generator, which increases the production rate by simultaneously produ...

Capsular contracture is a common complication after breast augmentation surgery. This study pathologically evaluated the soft-tissue response to surface modifications in both smooth and textured tissue expander prostheses. METHODS Smooth tissue expanders and textured tissue expanders in 5 cases each were used for breast reconstruction after mastectomy. Histological samples were harvested from...

Yunnan Baiyao is a well-known Chinese herbal medicine that has been used as a haemostatic drug for nearly 100 years. The aim of this clinical trial was to evaluate the efficacy and safety of Yunan Baiyao capsules on the reduction of blood loss in bimaxillary orthognathic surgery. 87 consecutive patients scheduled for simultaneous maxillary Le Fort I osteotomies and bilateral sagittal split ramu...

OBJECTIVE To validate a method for determining the simvastatin content of compounded capsules, using high performance liquid chromatography. METHODS Eighteen samples of simvastatin 40 mg capsules from compounding pharmacies in the cities of São Paulo, Guarulhos, São Bernardo do Campo and Campinas, Southeastern Brazil, prescribed for fictitious patients were assessed. The analyses were based o...

Heidelberger and Avery’s early experiments hinged on a simple element: nitrogen. Based on its presence or absence, the duo showed that the antibody-reactive substances on pneumococcal bacterial capsules were nitrogen-free carbohydrates, and that the reacting antibodies were nitrogencontaining proteins (see “How Heidelberger and Avery sweetened immunology” JEM 202:1306). The discovery that antib...

The recent preparation of levansucrase, like that of dextransucrase and phosphorylase, brings a new and powerful tool to bear on the study of macromolecular biosynthesis (Hestrin, Avineri-Shapiro & Aschner, 1943; Hestrin & Avineri-Shapiro, 1943; Hehre & Sugg, 1942; Stacey, 1942, 1943; cf. also Cori, 1939; Hanes, 1940; Behrens & Bergmann, 1939). Recent work on polysaccharide production in vitro ...
