Age differences in organophosphorus nerve agent-induced seizure, blood brain barrier integrity, and neurodegeneration in midazolam-treated rats.

Exposure to organophosphorus nerve agents irreversibly inhibits acetylcholinesterase and may lead to cholinergic crisis and seizures. Although benzodiazepines are the standard of care after nerve agent-induced status epilepticus, when treatment is delayed for up to 30 min or more, refractory status epilepticus can develop. Adult male rodents are often utilized for evaluation of therapeutic efficacy against nerve agent exposure.

Association between Locoregional Failure and NFE2L2/KEAP1/CUL3 Mutations in NRG/RTOG 9512: A Randomized Trial of Radiation Fractionation in T2N0 Glottic Cancer.

Purpose: NFE2L2/KEAP1/CUL3 mutations have been validated for radiation resistance in cell-based assays and animal models. However, clinical validation of these biomarkers has been challenging due to multimodality treatment regimens. This study aims to investigate the association between NFE2L2/KEAP1/CUL3 mutations and patient outcomes, including local failure (LF), locoregional failures (LRF), disease-free survival (DFS) and overall survival (OS), using samples from a phase III trial in which patients were treated with radiation monotherapy at 2 controlled doses.

In Planta Ectopic Expression of Two Sub-types of Tomato Cellulose Synthase-like M (CslM) Genes Affects Cell Wall Integrity and Supports a Role in Arabinogalactan and/or Rhamnogalacturonan-I Biosynthesis.

Diversification of the cellulose synthase superfamily of glycosyltransferases has provided plants with the ability to synthesise varied cell wall polysaccharides such as xyloglucan, mannans and the mixed-linkage glucans of cereals. Surprisingly, some but not all members of the cellulose synthase-like M (CslM) gene family have recently been shown to be involved in the glycosylation of the aglycone core of a range of triterpenoid saponins. However, no cell wall activity has yet been attributed to any of the CslM gene family members.

Beneficial Soil Fungus Kills Predatory Nematodes with Dehydropeptides Translocating into the Animal Gut.

is a mold fungus that has gained attention for its positive correlation with soil health, plant growth, and applications as a crop biocontrol agent to suppress the threats of nematode pests. To date, the mechanisms underlying the protective traits of against these plant parasites have remained elusive. Here we report that abundantly produced peptidic biosurfactants, malpinin A-D, exhibit robust inhibitory activity against nematodes.
