based on the molecular modeling studies on two major families of anxiolytics and sedative hypnotics (benzodiazepines and barbiturates) a series of phthalimide derivatives were prepared from corresponding di-methyl phthalate derivatives in two steps, namely trans-amidification and ring closer of di-methyl phthalate with urea and base catalysed condensation of 4-bromobenzyl chloride and benzoyl c...

background and objectives cannabinoids which are active compounds of marijuana show some pharmacological effects similar to the opioids. there are also functional interactions between both cannabinoid and opioid systems. in this study we investigated the role of cannabinoid receptors in central amygdala and its interaction with opioid system.   methods in the present study, we investigated the ...

In this paper we generalize the max plus algebra system of real matrices to the class of real tensors and derive its fundamental properties. Also we give some basic properties for the left (right) inverse, under the new system. The existence of order 2 left (right) inverses of tensors is characterized.

conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

in this article cuo/water nanofluid was synthesized by using polyvinylpyrolidone (pvp) as the dispersant.  thenanofluid stability period and the heat transfer enhancement were determinedby measuring the thermal conductivities. to study the nano-fluid stability, zeta (ζ) potential, and absorbency were measured under different ph values and pvp surfactant concentrations; also thermal conductivity...

− The variability of the molar fraction of atmospheric CO2 (xCO2 ) and wind speed and direction were investigated in a coastal embayment located in the west European coast, ría de Vigo, NW Spain, along daily and seasonal time scales. Observations in the ría showed that xCO2 a on a short time scale presented a much wider variability than seawater molar fraction (xCO2 ), in addition, a significan...

The leaves are used ethnomedicinally in Nigeria and other parts of the world for insomnia and anxiety among other uses. The investigations sought scientific evidence for the ethnomedicinal use of the leaves for the management of insomnia and anxiety as well as the neural mechanisms for the activities. The sedative and anxiolytic effects of the extracts of the leaves of Stachytarpheta cayennensi...
