Steric Effects in Isopropyl‐Substituted (β‐Diketiminato)Iron Complexes

European Journal of Inorganic Chemistry, EarlyView.
An isopropyl‐substituted β‐diketiminate ligand is shown to integrate aspects of its methyl and tert‐butyl counterparts in the preparation of iron complexes. As in the methyl system, it is synthesized in a single step but, like the tert‐butyl analog, it provides sufficient steric shielding to support otherwise unstable compounds.

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry

European Journal of Organic Chemistry, EarlyView.
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Preoperative limbic cortical thinning in mesial temporal lobe epilepsy surgical candidates is associated with pre‐existing and de novo postoperative depression

Epileptic Disorders, EarlyView.
Abstract Objective Depression is common in mesial temporal lobe epilepsy (mTLE), but its neuroanatomical basis—and overlap with major depressive disorder (MDD)—remains poorly defined. We investigated whether the cortical and subcortical alterations reported in MDD are also present in mTLE and leveraged the frequent occurrence of depression after ...

Efficacy of fenfluramine in a pediatric epilepsy patient with a pathogenic SV2A variant: A case report

Epileptic Disorders, EarlyView.
Abstract Pathogenic SV2A gene variants have been reported as causes of epilepsy and are often associated with drug resistance and susceptibility to fever‐related seizures. No highly effective treatments have been established for this condition. We report a female patient with a family history of epilepsy who developed generalized seizures associated ...

2,4-D plasmids and persistence

Nature, 1977
ACCORDING to the UN Food and Agricultural Organisation production year book of 1974, 27×10 kg of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) were consumed in 1973, making this the most extensively used of all pesticides. One desirable characteristic of 2,4-D, apart from its efficacy as a herbicide, is its lack of persistence in the environment,

2,4-D dissipation in field soils after applications of 2,4-D dimethylamine salt and 2,4-D 2-ethylhexyl ester

Environmental Toxicology and Chemistry, 1997
Abstract 2,4-Dichlorophenoxyacetic acid (2,4-D) was first registered in 1947 as an agricultural herbicide, and it is still the most widely used herbicide worldwide. End-use products, however, are generally formulated as inorganic or amine salts, or as esters.

Engineering 2,4-D resistance into cotton

Theoretical and Applied Genetics, 1992
To reduce damage by drift-levels of the herbicide 2,4-dichlorophenoxyacetic acid, we have engineered the 2,4-D resistance trait into cotton (Gossypium hirsutum L.). The 2,4-D monooxygenase gene tfdA from Alcaligenes eutrophus plasmid pJP5 was isolated, modified and expressed in transgenic tobacco and cotton plants.

2,4-D DEGRADATION AND 2,4-D DEGRADING MICROORGANISMS IN SOILS1

Soil Science, 1984
ABSTRACT In laboratory studies on Cecil loamy sand and Webster sandy clay loam, I examined the influence of soil-water tension and soil temperature on 14C-2,4-D degradation and the formation of nonextractable 14C-residues, and I correlated the degradation rate with the growth rate of 2,4-D degrading microorganisms. 14C-2,4-D rapidly mineralized in the

Animal models in the neurotoxicology of 2,4-D

Human & Experimental Toxicology, 2019
2,4-D is a selective pre- and postemergence herbicide used for several crops. It is hazardous for the environment and risk for humans; therefore, several studies attempt to evaluate its effects and consequences of its use. The nervous system is supposedly a target for this herbicide, and this comprehensive review gathers the information about animal ...
