Zero-field NMR J-Spectroscopy of Organophosphorus Compounds

, 2020
In this paper, we report the results of theoretical and experimental studies on basic organophosphorus compounds using zero-field NMR, where spin dynamics are investigated in the absence of a magnetic field with the dominant heteronuclear J-coupling. We

Enhancing Paraoxon Binding to Organophosphorus Hydrolase Active Site

, 2021
Organophosphorus (OP) compounds are among the most toxic of chemical substances and widely used as insecticides, pesticides, and chemical warfare agents. The most important enzyme inhibited by OP compounds is acetylcholinesterase (AChe).

Alleviation of Tri-o-cresyl Phosphate-Induced Myelin Sheath Damage to Sciatic Nerves by Exogenous Progesterone Pretreatment

Toxics
Some organophosphorus compounds can induce delayed neurotoxicity, which is characterized by ataxia, also known as organophosphate-induced delayed neurotoxicity (OPIDN).

Organophosphorus poisoning: A rare case of upper extremity deep vein thrombosis

Indian Journal of Health Sciences and Biomedical Research KLEU, 2016
A 32-year-old female was admitted with Organophosphorus (OP) poisoning and was managed with gastric lavage, intravenous pralidoxime, and atropine. On the 3rd day, she developed swelling and pain in the right upper extremity. Color Doppler confirmed upper

Breaking the Mold: Electrophilic Hydrophosphanation Emerges

Chemistry – A European Journal, EarlyView.
Electrophilic hydride attack on the olefin, instead of the classical nucleophilic addition by a phosphanido ligand, is unveiled in rhodium‐catalyzed olefin hydrophosphanation. This hydride‐driven pathway operates for both activated and inactivated olefins, with transition states characterized by elongated Rh─H bonds and nascent C─H bond formation ...

Demographic profile of patients with acute poisoning in the emergency department of a tertiary care center and their outcomes

Journal of Karnali Academy of Health Sciences
Introduction: Acute poisoning is a major public health issue in Nepal, driving emergency visits, admissions, and deaths mainly from accessible organophosphorus pesticides. Patterns vary by region, with insecticides dominant in developing areas like Nepal,

Flipping the Card With Enantiodivergent Organocatalysis

Chemistry – A European Journal, EarlyView.
This minireview elaborates on recent organocatalytic strategies for achieving enantiodivergence—the ability to access both product enantiomers using a single chiral catalyst. It highlights how achiral stimuli, such as solvent polarity and chemical additives, along with minimal catalyst modifications, trigger stereochemical inversions in reactions ...
