1. The loosening of the egg capsule plug prior to escape of the veligers is shown to be chemically mediated in Nassarius obsoletus and N. trivittatus. 2. The hatching substance is not produced continuously during development, but rather in a short pulse beginning just prior to hatching and ending within 4 hours of escaping from the capsule, for N. obsoletus. 3. The hatching substance produced b...

[reaction: see text] NMR diffusion measurements were used to probe the differences in the characteristics of the hexameric capsule of [c]-undecane resorcin[4]arene (1b) in a CDCl(3) solution in the absence and presence of tetrahexylammonium bromide (THABr). It was found that the nonencapsulated THABr forms a 1:1 complex with 1b, which is in fast exchange with its constituents. We found that wat...

The Regional Superfund Ground Water Forum is a group of EPA professionals, representing EPA's Regional Superfund Offices, committed to the identification and the resolution of ground water issues impacting the remediation of Superfund sites. The Forum is supported by and advises the Superfund Technical Support Project. Remediation of trichloroethylenecontaminated soils and ground waters is an i...

a new drug is calculated to induce other medical men to try it, with eventual benefit to suffering humanity, however obscure the member of our profession may be, from whom the testimony may come. My first acquaintance with the value of the suprarenal capsule as a medicinal agent took place within two months of my starting practice in Bombay. Four fivegrain tablets of the capsule dissolved in a ...

Previous studies with 31 strains of Serratia marcescens, including 28 reference O-serotype strains, have indicated that 19 of them have an acidic polysaccharide which copurifies with lipopolysaccharide during phenol-water extraction. Polysaccharide in crude extracts from 18 of the 19 strains was precipitated with Cetavlon (hexadecyltrimethyl ammonium bromide), and capsules were demonstrated aro...

DESCRIPTION INVIRASE brand of saquinavir mesylate is an inhibitor of the human immunodeficiency virus (HIV) protease. INVIRASE is available as light brown and green, opaque hard gelatin capsules for oral administration in a 200-mg strength (as saquinavir free base). Each capsule also contains the inactive ingredients lactose, microcrystalline cellulose, povidone K30, sodium starch glycolate, ta...

Poly(terephthalamide) microcapsules can be reproducibly and easily prepared by interfacial polycondensation around emulsion droplets in water. Oil drops of cyclohexane/chloroform mixture stabilized with poly(vinyl alcohol) containing terephthaloylchloride serve as soft template. The interfacial polycondensation starts immediately after addition of an amine mixture (hexamethylenediamine/diethyle...

OBJECTIVES To evaluate the effectiveness of capsule endoscopy in the management of patients with obscure gastrointestinal bleeding. METHODS A prospective descriptive study was conducted at surgical unit IV, Civil Hospital Karachi over a period of 2 years from December 2007 to November 2009. Twenty eight consecutive patients presenting with obscure gastrointestinal bleeding were included in th...

We present in this work simulations using the finite difference approximation in 2D for the melting of an encapsulated phase-change material suitable for heat storage applications; in particular, we study CaCl2·6H2O in a cylindrical encapsulation of internal radius 8 mm. We choose this particular salt hydrate due to its availability and economic feasibility in high thermal mass building walls o...

This study aimed to compare thickness of the capsule, corium, and soft tissues measured ultrasonographically and macroscopically in selected regions of bovine claws. A hundred and twenty claws (n = 120) of 15 healthy Holstein bovines were obtained. After cleaning the claws, ultrasonographic measurement of the capsule, corium, and soft tissues was performed while submerging the claws in a water ...
