One of the most nervous system evolution are memory and learning in humans. Learning is a skill that enhances synaptic activity in the hippocampus of prefrontal cortex. In fact, basic passive learning is communication between the conditioned and Unconditioned stimulation. Passive learning involves three steps: habit, education and remember. According to the results of investigations, the hippoc...

Linear ion-trap (LIT) MS2 mass spectrometric approach toward locating the position of double bond(s) of unsaturated long-chain fatty acids and toward discerning among isomeric unsaturated fatty acids as dilithiated adduct ([M-H+2Li]+) ions are described in this report. Upon resonance excitation in a LIT instrument, charge-remote fragmentation that involves beta-cleavage with gamma-H shift (McLa...

On the basis of the unsaturated fatty acids which they synthesize, protists can be grouped in a meaningful way. Thus, the unsaturated fatty acids of the true slime mold are identical with the unsaturated fatty acids of the soil amoebae Acanthumoeba and Hartmannella but have no resemblance to those of the cellular slime mold Dictyostelium. Among the zooflagellates, Leishmania enriettii and Leish...

There is good scientific evidence that dietary fatty acid composition is involved in the aetiology of many diseases. Increasing the supply of n-3 polyunsaturated fatty acids (PUFA) may reduce the risk of CHD. Several scientific organizations (for example, see Department of Health, 1991, 1994; British Nutrition Foundation, 1992; Scientific Committee for Food, 1993; Food and Agriculture Organizat...

Background and objectives: Withania coagulans Dunal (Solanaceae) fruits are recommended to treat asthma, dyspepsia, biliousness, flatulent colic, liver complaints, intestinal infections, strangury, wounds and as diuretic, emetic and sedative agent in Indian traditional system of medicine. The objective of this study was to describe the systematic fatty acid composition...

In this study, the oil contents, fatty acid composition and tocopherol contents of sesame seed and oils belong to different countries were determined. The oil contents of materials changed between 49.22% (India) and 56.16% (Nigeria-Kanu). The major saturated fatty acids in sesame seed oils were palmitic (6.06-9.03%), stearic (5.29-6.42%) acids with small 20:0 (0.19-0.71%) acids. The main un...

The technique of gas-liquid chromatography-chemical ionization mass spectrometry can easily identify trace peaks and unresolved peaks on gas-liquid chromatography, utilizing MH(+) ions of chemical ionization mass spectra. In polyunsaturated fatty acid methyl esters such as C22:5 and C22:6, the determination of molecular weights that are difficult to determine by electron impact mass spectrometr...

The influence of various fatty acids of 14-18 carbon chain lengths on the binding of calcium to human serum albumin was studied. The cis-unsaturated fatty acids (myristoleic, palmitoleic, oleic, and linoleic) caused a much larger increase in the affinity and maximum binding of calcium for albumin than did saturated fatty acids (myristic, palmitic, and stearic). For the unsaturated fatty acids, ...

The effects of saturated and unsaturated fatty acids on the growth of Bordetella pertussis strain 114 in defined medium were tested. Individual fatty acids were found to be either inhibitory or stimulatory to growth, depending on concentration. Myristic (C14), pentadecanoic (C15), and palmitic (C16) acids were the most inhibitory saturated fatty acids tested. B. pertussis 114 was extremely sens...

Increasing prevalence of allergic diseases with an inadequate variety of treatment drives forward search for new alternative drugs. Fatty acids, abundant in nature, are regarded as important bioactive compounds and powerful nutrients playing an important role in lipid homeostasis and inflammation. Phytochemical study on Typhonium blumei Nicolson and Sivadasan (Araceae), a folk anti-cancer and a...
