Case management services and long-term care insurance benefits.

Early versions of long-term care insurance were medically driven and institutionally biased. By design, these policies discouraged inappropriate or ineffective use of covered services. Newer long-term care policies have sought to meet policyholders' needs for greater flexibility in covered services and eligibility requirements.

Absence of antisperm antibodies and factors influencing sperm motility in the cul-de-sac fluid of women with endometriosis.

No detrimental effect on sperm motility characteristics by PF from women with low-stage endometriosis was documented when incubated for 3 to 6 hours. Although 1 of 31 women with endometriosis possessed IgA and IgG to sperm in her PF, its significance remains undetermined.

Cryopreservation of human spermatozoa. III. The effect of cryoprotectants on motility.

A series of experiments was conducted to examine potential toxic effects of cryoprotectants on motility of human spermatozoa. The data indicated that exposure of spermatozoa to cryoprotectant medium for as little as 15 minutes at room temperature caused a reduction in motility. This reduction in motility was caused by glycerol.

Factors affecting the cryosurvival of mouse two-cell embryos.

A series of 4 experiments was conducted to examine factors affecting the survival of frozen-thawed 2-cell mouse embryos. Rapid addition of 1.5 M-DMSO (20 min equilibration at 25 degrees C) and immediate, rapid removal using 0.

Cryopreservation of human spermatozoa. II. Postthaw chronology of motility and of zona-free hamster ova penetration.

Postthaw dynamics of motility maintenance and ability to penetrate zona-free hamster ova were examined with human sperm. Ten semen samples were each divided into two equal volumes; one was cryopreserved while the other half remained untreated. Frozen samples were thawed, and initial evaluations for motility and hamster egg penetration were made on both untreated and frozen-thawed samples.
