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...

STATEMENT OF THE PROBLEM The increase in white blood cell count (WBC) and platelet count due to systemic inflammation and infection is considered a risk factor for cardiovascular diseases. These parameters increase in periodontal disease. A decrease in WBC and platelet counts by periodontal therapy may decrease the risk for cardiovascular disease. PURPOSE OF THE STUDY The present study is a t...

Urinary amino acids were determined in 162 individuals (62 young non-vegetarians, 24 elderly non-vegetarians, 40 young vegetarians and 36 elderly vegetarians) by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). The two methods used in this study were compared. The difference in the percentage frequencies of detection by TLC and HPLC in non-vegetarian group was ...

Among various meanings of TLC like The Last Cigarette—a smoking cessation program that offers numerous resources and tools to assist smokers in their quit efforts, there is also Thin Layer Chromatography, an analytical technique, which can be useful to check the process of quitting smoking and allow to observe differences in nicotine metabolism. The task of this research was checking sufficienc...

Understanding the total lymphocyte count (TLC)-CD4 count relationship could aide design predictive instruments for making clinical decisions during antiretroviral therapy, especially in underserved resource-poor settings. We performed multiple regression analyses to assess the prediction of CD4 count using TLC on 771 participants with 4,836 visits. In linear and logistic regression TLC, hemoglo...

Nonmitochondrial ADP/ATP translocase is an energy parasite enzyme. Its encoding gene, tlc, is found only in Rickettsiales, Chlamydiales, and plant and alga plastids. We demonstrate the presence of tlc in Parachlamydia acanthamoebae. This gene shares more similarity with the tlc1 gene of Chlamydiaceae and the tlc of plant and alga plastids than with the tlc2 gene of Chlamydiaceae. Phylogenetic a...

This paper highlights the status of thin-layer chromatography (TLC) of mycotoxins in various sample matrices. The outstanding merits of TLC in the field of the qualitative and quantitative determination of mycotoxins have been briefed. A comparison between different TLC methods and TLC with HPLC, enzyme-linked immunosorbent assay and GC methods, etc. is made, in general.

This study evaluated total lymphocyte count (TLC) as a substitute marker for CD4+ cell counts to identify patients who need prophylaxis against opportunistic infection (CD4 < 200 cells/mm(3)) and patients with CD4 < 350 cells/mm(3) (Brazilian threshold value of CD4 count to define AIDS). We evaluated TLC and CD4+ cells count of 1,174 HIV-infected patients, in Salvador, Brazil, from May 2003 to ...
