The anti-AChE activity of phosphoramidates has been noticed for many years. Because of the wide application of phosphoramidates in recent years, there has been a continuing research for synthesis, purification and identification of effective and safe derivatives. In this study some rodenticides with the general formula Me 2 NP(O)( p-OC 6 H 4 -X) 2 , where X ¼ H, CH 3 , Cl, have been synthesized in water (without organic solvent) and characterized by 31 P, 31 P { 1 H}, 13 C and 1 H NMR spectroscopy. Since lipophilicity has been recognized for its importance in QSAR studies, efforts have been made to determine the logP values. The ability of these rodenticides to inhibit human acetylcholinesterase (hAChE) has been predicted with PASS (Prediction of Activity Spectra for Substances) software (version 1.917) and then has been evaluated by a modified Ellman's assay and spectrophotometric measurements.
This study explores the relationship between daylight exposure in urban residential units and the mood/happiness of nonworking female residents (housewives) in Isfahan, Iran. A growing body of evidence points to the physiological and psychological benefits of daylight, yet few studies have focused on the relationship between residential daylight and women's mental health. A cross‐sectional study was conducted using two‐stage random cluster sampling of nonworking female occupants of buildings in four residential districts. Mood/happiness was determined using the Oxford Happiness Inventory and the Fordyce Happiness Inventory. Spearman's rank correlation analysis was used to determine the relationship between the variables. A significant relationship was found between residents’ happiness and the amount of daylight in their residential units (Oxford Inventory, r = 0.68, P < 0.05; Fordyce Inventory, r = 0.53, P < 0.05). The findings suggest that features of physical residential environments, such as daylight, may be linked to the happiness of housewives. Persons belonging to various demographic groups who spend the majority of their time indoors (e.g., housewives, children, elderly individuals, and people with disabilities) are most dependent on architecture and environmental design for their well‐being, and therefore, are most affected by design decisions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
