Phospholipids are the main component of naturally occurring bilayers. These phospholipids include phosphatidylcholines (PC), phosphatidylethanolamines (PE) and phosphatidylserines (PS) [1]. The key common feature that bilayer-forming compounds share is their amphiphilicity ie., they have defined polar and non-polar regions. This is the reason the non-polar regions orientate themselves towards t...

2014 The elastic constants, magnetic susceptibility, refractive index and density are reported for p,p’-diheptylazobenzene. The behaviour of the elastic constants of this non polar compound is very similar to that of related polar compounds. The anisotropy of both the static and the highfrequency permittivity is proportional to the anisotropy of the susceptibility, as observed earlier for the h...

Iminodiacetic acid (IDA) is dicarboxylic acid amine, which may produce stronger interaction with polar or charged compounds than bidentate α,β-amino acid. In this article, a novel type of tridentate zwitterionic HILIC stationary phase was prepared by covalently bonding N-benzyl IDA on silica gel via copper(I) catalyzed Huisgen azide-alkyne 1,3-dipolar cycloaddition (CuAAC). The structure of thi...

Trigonella foenum-gracum L. (Fenugreek) (Leguminosae) is employed as an herbal medicine. Its seeds are known for their carminative, tonic and antidiabetic effects. In the present study, we investigated the hypoglycaemic activities of the hydroalcoholic, ethanolic and chloroformic extracts of the Trigonella foenum-gracum seeds in streptozotocin-diabetic rats using interperitoneall (i.p.) adminis...

Inclusion complexes of 2-[Arylidenamino]-1,3,4-thiadiazino[6,5b]indoles have been prepared with β-cyclodextrin so as to increase the solubility of these compounds in polar medium which may increase theirbioaccessibility. The formation of inclusion complexes is known from the study of changes in physical andspectral properties of the compounds. The stability of the inclusion complexes has been s...

The main purpose of this work was the preliminary qualitative study of organic compounds in wastewaters of swine slaughterhouses. The samples were collected in a local abattoir and submitted to Liquid-Liquid Extraction (LLE) and Solid-phase Extraction (SPE) with XAD-4 resin as stationary phase. The instrumental analysis was performed by Gas Chromatography with Mass Spectrometer Detector (GC/MSD...

Images obtained during MESSENGER's low-altitude campaign in the final year of the mission provide the highest-spatial-resolution views of Mercury's polar deposits. Images for distinct areas of permanent shadow within 35 north polar craters were successfully captured during the campaign. All of these regions of permanent shadow were found to have low-reflectance surfaces with well-defined bounda...

this study was conducted to evaluate the cytoprotection of various extracts and bioactive compounds found in pistacia vera againts cytotoxicity, ros formation, lipid peroxidation, protein carbonylation , mitochondrial and lysosomal membrane damages in cell toxicity models of diabetes related carbonyl (glyoxal) and oxidative stress (hydroperoxide). methanol, water and ethyl acetate were used to ...
