Abstract: A lens, having an optical power surface, which may have multiple radii portions or aspherical portions as well as spherical portions, is molded in a coined mold. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.

Abstract: A method for alleviating emesis caused by chemotherapy which comprises administering an antiemetic agent or a pharmaceutically acceptable salt thereof to a patient in conjunction with the administration of a chemotherapeutic agent, said antiemetic agent being represented by the formula (I) ##STR1## wherein Z represents a substituent such as a lower alkyl group, a methoxyethoxymethyl group, or a benzoylmethyl group; or Z in conjunction with the adjacent position represents the atoms necessary to complete a 5 to 7 membered saturated or unsaturated oxygen-containing ring; R represents a hydrogen atom, a halogen atom, a lower alkyl group, a cycloalkyl group, a lower alkoxy group, an amino group, a lower alkyl-substituted amino group, an acylamido group, a sulfamoyl group, a sulfonamido group or a nitro group; n is an integer of 1 to 3; W is a straight chain or branched chain alkylene group of 1 to 4 carbon atoms; and X represents the atoms necessary to complete a 5 or 6 membered ring; said antiemetic agent being

Abstract: A multi-channel electrophoresis apparatus is fitted with a detection means disposed substantially across the width of the medium, intersecting all channels. The detection means senses components of samples as they migrate past the detection means and identifies the channel in which the detected components are located. In the preferred embodiment, the samples are tagged with radioisotopes which are detected by the detector.

Abstract: A method for simultaneously isolating DNA, RNA and/or protein fractions from a crude biological mixture containing DNA, RNA and/or protein fractions is disclosed. The method comprises adding the crude biological mixture to an aqueous solution of cesium trifluoroacetate, the solution having a density from about 1.4 to about 1.6 g/ml, and centrifuging the resulting mixture under ultracentrifugation conditions.

Abstract: A method and apparatus for use in endoscopic examination of a hollow internal organ, such as hysteroscopic examination of the uterus, includes an inflatable cuff for infusing a pressurized viscous fluid into the interior of the uterine cavity for minimizing distortion of an image of the organ interior viewable through the endoscope. The viscous fluid is an optically clear innocuous liquid having a predetermined viscosity such as between 130 and 300 centistokes at 20.degree. C, and a predetermined optical density, such as a refractive index of 1.3912 at 21.degree. C. This viscous fluid is contained in a self-contained sterile packet reservoir which is removably retained within the inflatable cuff with the viscous fluid being pressurized and released from the reservoir into the endoscope to be infused into the organ interior under the controlled pressure of the inflated cuff surrounding the fluid reservoir packet.
