Redesigning the Warren Animal Shelter

The new shelter should incorporate improved natural lighting and ventilation, adequate space for laundry facilities and more space for the animals\u27 living and bathing needs. The design should consider how to prevent dogs from barking and disturbing one another while in the kennels. Increased storage is necessary for the animal shelter to contain the food and living amenities for the incoming animals

Identification and selective expansion of functionally superior T cells expressing chimeric antigen receptors

Background: T cells expressing chimeric antigen receptors (CARs) have shown exciting promise in cancer therapy, particularly in the treatment of B-cell malignancies. However, optimization of CAR-T cell production remains a trial-and-error exercise due to a lack of phenotypic benchmarks that are clearly predictive of anti-tumor functionality. A close examination of the dynamic changes experienced by CAR-T cells upon stimulation can improve understanding of CAR–T-cell biology and identify potential points for optimization in the production of highly functional T cells. Methods: Primary human T cells expressing a second-generation, anti-CD19 CAR were systematically examined for changes in phenotypic and functional responses to antigen exposure over time. Multi-color flow cytometry was performed to quantify dynamic changes in CAR-T cell viability, proliferation, as well as expression of various activation and exhaustion markers in response to varied antigen stimulation conditions. Results: Stimulated CAR-T cells consistently bifurcate into two distinct subpopulations, only one of which (CARhi/CD25+) exhibit anti-tumor functions. The use of central memory T cells as the starting population and the resilience—but not antigen density—of antigen-presenting cells used to expand CAR-T cells were identified as critical parameters that augment the production of functionally superior T cells. We further demonstrate that the CARhi/CD25+ subpopulation upregulates PD-1 but is resistant to PD-L1-induced dysfunction. Conclusions: CAR-T cells expanded ex vivo for adoptive T-cell therapy undergo dynamic phenotypic changes during the expansion process and result in two distinct populations with dramatically different functional capacities. Significant and sustained CD25 and CAR expression upregulation is predictive of robust anti-tumor functionality in antigen-stimulated T cells, despite their correlation with persistent PD-1 upregulation. The functionally superior subpopulation can be selectively augmented by careful calibration of antigen stimulation and the enrichment of central memory T-cell type.

Effects of Sugar on Efficacy of Three Residual Fly Control Insecticides, 1988

Abstract Plywood panels (61 cm × 91 cm) were treated with Alfacron 50 WP (1.25%), Ectiban WP (1.25%), and Fly Killer D (0.25%), with and without sugar (120 g/1 of finished spray) added to the spray mixture. Untreated panels (no treatment and sugar plus water) were also included in the group of treatments. A section of rain gutter was placed along the bottom of each panel to collect the dead flies. Four replicates of each treatment were arranged in a randomized complete block design, with panels situated along the edge of a poultry house. The test was initiated on 15 Apr with flies being collected weekly for 8 wk.</jats:p
