Kinetic

Kinetic check details data and (1)H-nuclear magnetic resonance analyses showed that simultaneous polymerization of butadiene and styrene provided copolymers with a predominantly random distribution. By increasing the styrene content, the thermal properties of these copolymers were modified; polymers with 80% content of 1,4-trans units and 5% of styrene presented an endothermic transition at or slightly below room temperature (20 degrees C), corresponding to the crystalline monoclinic form of high 1,4-trans polybutadiene, whereas copolymers with 25-50% styrene content were amorphous. The glass transition temperature of these copolymers increased

significantly as the styrene content was increased. Both the block and random copolymers have a sufficient number of 1,4-trans units to display a regular distribution of structural units that makes them susceptible to strain-induced crystallization, which is important for the manufacture of products such as high-performance tires.

“PURPOSE: To evaluate the visual outcomes and patient satisfaction with modified pseudophakic monovision.

SETTING: Tertiary teaching hospital.

METHODS: This prospective study comprised patients with emmetropia after first-eye cataract

Surgery who were offered monovision for the second-eye surgery with a moderate myopic target refraction (-1.00 to -1.50 diopters [D]). Visual acuity, contrast sensitivity, stereopsis, RepSox patient satisfaction, and degree of spectacle independence were measured preoperatively and 3 to 4 months postoperatively.

RESULTS: The study evaluated 52 eyes of 26 patients with a mean anisometropia between the near eye and the distance eye of 1.16 D. Uncorrected distance visual acuity was at least 20/30 in 96% of patients, GSI-IX molecular weight with 92% achieving N8 (J4) or better uncorrected near acuity.

Good stereopsis and contrast sensitivity were maintained. Patients were generally satisfied with the surgery. One fourth of patients were completely independent of spectacles; 1 patient was totally dependent on spectacles. No patient required intraocular lens (IOL) exchange or other refractive corrective procedures.

CONCLUSION: Monovision with modest refractive targets achieved good visual function and patient satisfaction without the inherent risk for troublesome visual symptoms associated with multifocal IOLs. J Cataract Refract Surg 2009; 35:998-1002 (C) 2009 ASCRS and ESCRS”
“The purpose of this study was to investigate the in vivo absorption enhancement of a nucleoside (phosphoramidate prodrug of 2′-methyl-cytidine) anti-viral agent of proven efficacy by means of intestinal permeation enhancers. Natural nucleosides are hydrophilic molecules that do not rapidly penetrate cell membranes by diffusion and their absorption relies on specialized transporters.
