Blood Carboxyhemoglobin Concentrations as a Diagnostic Biomarker of Hemolytic Anemias in Cats.

Background: Endogenous carboxyhemoglobin (COHb) production is a byproduct of hemoglobin metabolism.

Hypothesis: Blood carboxyhemoglobin concentrations are higher in cats with hemolytic anemia (HA).

Animals: Twenty cats with HA, 29 cats with non-HA, and 22 controls were prospectively followed.

Visual and subject-reported outcomes of a wavefront shaping extended depth of focus intraocular lens implanted bilaterally with monovision.

Purpose: To report visual and subject-reported outcomes after bilateral implantation of non-diffractive extended-depth-of-focus (EDoF) intraocular lens (IOL) (AcrySof IQ Vivity) with monovision correction during cataract or refractive lens exchange (RLE) surgery.

Setting: Europe, Australia, and New Zealand.

Design: Subgroup analysis of Vivity registry.

Infections caused by extended-spectrum beta-lactamase-producing Enterobacterales in hospitalized neonatal foals: Can colonization predict infection?

Background: Infections with extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-PE) contribute to morbidity and mortality in human neonates. In foals, data are scarce.

Objectives: Determine the association between ESBL-PE gastrointestinal colonization on hospital admission and infections in hospitalized neonates.

Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology.

Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among researchers in the decisions they make regarding statistical analyses. A growing array of studies has explored this analytical variability in different fields and has found substantial variability among results despite analysts having the same data and research question.

RNAi of the elastomeric protein resilin reduces jump velocity and resilience to damage in locusts.

Resilin, an elastomeric protein with remarkable physical properties that outperforms synthetic rubbers, is a near-ubiquitous feature of the power amplification mechanisms used by jumping insects. Catapult-like mechanisms, which incorporate elastic energy stores formed from a composite of stiff cuticle and resilin, are frequently used by insects to translate slow muscle contractions into rapid-release recoil movements. The precise role of resilin in these jumping mechanisms remains unclear, however.
