Canine corneal endothelial cell analysis using vital dyes and light microscopy.

Purpose: To evaluate the use of vital dyes and light microscopy for assessing canine corneal endothelial morphology ex vivo.

Methods: The corneas of 40 canine eyes (n = 20 dogs) enucleated <24 h following euthanasia or death were isolated and flat-mounted on a slide. Corneal endothelium was stained via 0.

Serum Cholesterol Concentration on Admission in 415 Dogs Envenomated by as a Marker of Envenomation Severity and Outcome-A Retrospective Study.

() (), accounts for most envenomations in humans and dogs in Israel. In humans envenomed by , serum cholesterol concentration (sChol) is inversely correlated with envenomation severity. This study examined the utility of sChol upon admission in dogs envenomed by as an envenomation severity and outcome marker.

Use of bilateral superficial gluteal muscle flaps for the repair of ventral perineal hernia in dogs: A cadaveric study and short case series.

Objective: To describe bilateral mobilization of the superficial gluteal muscle (SGM) to treat ventral perineal hernias in dogs.

Study Design: Cadaveric study and short case series.

Sample Population: Male dog cadavers (n = 10) weighing between 5 and 42 kg and three dogs treated for ventral perineal hernia.

Evidence for trans-generational effects on egg maturation schedules in a syn-ovigenic parasitoid.

The lifetime reproductive success of a female parasitoid is limited by (1) host (or time) limitation - the number of hosts available for oviposition during its lifetime; and (2) egg limitation - its egg supply. Host limitation is expected to select for increased longevity and/or foraging efficiency, while increased fecundity is predicted to evolve under egg limitation. If the limiting factor varies, phenotypic plasticity in egg maturation schedules may be advantageous, i.

Phenotypic plasticity of pre-adult egg maturation in a parasitoid: Effects of host-starvation and brood size.

Larvae of parasitoid wasps develop on a single arthropod host, and often face resource limitation that induces a tradeoff between egg maturation and somatic growth. Part of the variation in the growth-reproduction allocation was shown to be heritable, but how the larval developmental environment affects this allocation is not well-known. Detection of life history tradeoffs is often facilitated under stress conditions.
