Acid Red 26 and 18 are two early synthetic dyes belonging to the monazo dye class. The molecular structure of this class is characterized by chromophoric azo group (NN) generally attached benzene or naphthalene derivatives containing electron withdrawing and/or donating groups as substituents. As both red have an OH in ortho- position respect group, they undergo azo-hydrazone tautomerism. In wo...

We observed in human and mouse skin that exposure to C. acnes resulted greatly increased epidermal lipids as indicated by bodily staining hypothesized this microbe may regulate keratinocyte lipid metabolism. To test this, keratinocytes (NHEKs) were exposed sterile supernatant showed a dose dependent increase Oil Red O (p-value <0.001), increases of ceramides, cholesterol free fatty acids detect...

A modified automated colorimetric micromethod for the determination of red cell 2,3-diphosphoglycerate (2,3-DPG) adapted from that of Grisolia et al (1969) is described. In the modified method, ethylenediaminetetra-acetic acid (EDTA) is not used and consequently concentrations of several reagents are changed. During the development of the method it was found that the presence of EDTA, either in...

Adeno-associated virus serotype 4 (AAV4) and AAV5 have different tropisms compared to AAV2 and to each other. We recently reported that alpha 2--3 sialic acid is required for AAV5 binding and transduction. In this study, we characterized AAV4 binding and transduction and found it also binds sialic acid, but the specificity is significantly different from AAV5. AAV4 can hemagglutinate red blood ...

The aim of this study was to obtain a basic knowledge of the fatty acid compositions and consequently, determination of diet for Turbo coronatus by means of fatty acids biomarkers. Samples were collected during a year (April, July, October 2007 and February 2008) in coastal areas of Chabahar Bay in Oman Sea. Biomarker fatty acids revealed that diet of Turbo coronatus included phytoplankton, zoo...

The composition of the phospholipids and of the total phospholipid fatty acids was determined in the plasma of 10 normal subjects. In addition the fatty acid composition of the plasma phosphatidyl ethanolamine, phosphatidyl serine, lecithin, sphingomyelin, and lysolecithin of 6 of the subjects was measured. A wide array of fatty acids was found in the plasma total phospholipid similar to that f...

in present investigation the biological leaching of aluminum by isolated fungi from red mud, the main waste product of the alkaline extraction of al from bauxite was studied. biological leaching experiments were carried out using indigenous, date and orange specimen fungi, aspergillus niger, penicillium simplicissimum notatum. savored dextrose chloramphenicol agar (sda) was used as medium for t...

Monounsaturated fatty acids (MUFA) are emerging health biomarkers, and in particular the ratio between palmitoleic acid (9cis-16:1) and palmitic acid (16:0) affords the delta-9 desaturase index that is increased in obesity. Recently, other positional and geometrical MUFA isomers belonging to the hexadecenoic family (C16 MUFA) were found in circulating lipids, such as sapienic acid (6cis-16:1), ...

Folic acid deficiency is very common in elderly patients who have a mean red cell volume greater than 94 fl. Eighteen out of 40 elderly patients with red cell macrocytosis who initially had normal red cell folate and serum B12 levels subsequently developed folic acid deficiency.
