Article Synopsis
- Paropsisterna bimaculata is a harmful pest for eucalyptus trees, leading to significant defoliation and even tree death in Tasmanian plantations, impacting wood production.
- The study focused on creating an ecoclimatic index model using CLIMEX software to predict where this pest might spread globally, identifying high-risk areas for eucalyptus crops.
- Results indicated that regions with temperate climates across Asia, Africa, Europe, Oceania, and America are especially vulnerable, with a notable risk present in Brazil's southern and southeastern areas, guiding prevention strategies.
Twenty-one simplified analogues of the natural product domoic acid were designed, synthesized, and then characterized at homomeric kainic acid (KA) receptors (GluK1-3,5). displays a high affinity for homomeric GluK5 receptors (IC = 432 nM) with a >40-fold selectivity over homomeric GluK1-3 subtypes and ≫100-fold selectivity over native AMPA and -methyl d-aspartate receptors. Functional studies of on heteromeric GluK2/5 receptors show no agonist or antagonist functional response at 10 μM, while a concentration of 100 μM at neuronal slices (rat) shows low agonist activity.

Synapse formation is critical for the wiring of neural circuits in the developing brain. The synaptic scaffolding protein S-SCAM/MAGI-2 has important roles in the assembly of signaling complexes at post-synaptic densities. However, the role of S-SCAM in establishing the entire synapse is not known.

In TLE, recurrent mossy fiber sprouting from dentate gyrus granule cells (DGCs) crea an aberrant epileptogenic network between DGCs which operates via ectopically expressed GluK2/GluK5-containing kainate receptors (KARs). TLE patients are often resistant to anti-seizure medications and suffer significant comorbidities; hence, there is an urgent need for novel therapies.

Here, we describe our experience with the use of casirivimab-imdevimab or bamlanivimab for the treatment of coronavirus disease 2019 (COVID-19) in HM/HCT patients.
Methods: This was a retrospective chart review at the University of Miami Hospital and Sylvester Comprehensive Cancer Center for HM/HCT patients with COVID-19 who received casirivimab-imdevimab or bamlanivimab from November 21, 2020, to September 30, 2021.
