In this research the lipid fraction of two strains of Streptococcus thermophilus was studied. Lipids were extracted by applying Folch method and fractioned by thin layer chromatography (TLC). Fatty acid composition was determined both before TLC, on the total fat extracted, and after TLC on diacylglycerol and apolar fractions. Gas chromatographic analysis was performed by using both flame ioniz...

Two chemical methods for characterization of micro organisms were compared: phospholipid ester-linked fatty acid (PLFA) analysis by gas chromatography/mass spectrometry, and intact phospholipid pro®ling (IPP) using liquid chromatography/electrospray ionization/mass spectrometry. Both methods were tested on ®ve reference pseudomonad strains: Pseudomonas putida mt-2, Pseudomonas putida F1, Burkho...

We prove that a subtle but substantial bias exists in a common measure of the conditional dependence of present outcomes on streaks of past outcomes in sequential data. The magnitude of this novel form of selection bias generally decreases as the sequence gets longer, but increases in streak length, and remains substantial for a range of sequence lengths often used in empirical work. We observe...

Cancer is one of the most common lethal diseases, and natural products have been extensively studied as anticancer agents considering their availability, low toxicity, and economic affordability. Plants belonging to the genus Aconitum have been widely used medically in many Asian countries since ancient times. These plants have been proven effective for treating several types of cancer, such as...

Abstract The SARS-CoV-2 outbreak and the corresponding COVID-19 pandemic has had continues to have a significant impact on health wellbeing of general population globally. University students are in unique position during as they confronted with substantial changes restrictions, both at governmental university-level. Stark lifestyle include social academic life. In order understand investigate ...
