The essential oils obtained by hydrodistillation from the stem, leaf and flower of Phlomis aucheri Boiss., which is endemic to Iran, stem, leaf and root of Teucrium polium L. and solvent free microwave extraction oil from leaf of Ajuga chamaecistus Ging. subsp. chamaecistus were analyzed by GC and GC/MS. Germacrene D (11.1%, 28.3% and 21.1%) was the main constituent in the stem, leaf and flower...

Background & Aim:Extracts of Roselle calyx,   possess compounds which could be considered as a great source of natural antioxidants.   In this project, antioxidant activities, phenolic compounds content and their   correlation analysis on calices of Roselle (Hibiscus sabdariffa) was investigated.  Experimental: Total polyphenolic compound, flavonoids and anthoc...

a new method for the determination of trace copper(ii) in food samples by cloud point extraction(cpe) combined with flame atomic absorption spectrometry(faas) is presented and evaluated. the method is based on the fact that hydrophobic complex of copper(ii) with sodium diethyldithiocarbamate (ddtc) was formed at ph 6.0 and subsequently the hydrophobic complex was extracted into surfactant-rich ...

Substantial evidence indicates that triglyceride-rich lipoprotein remnants are atherogenic. Additional research has, however, been limited by available methods for separation and quantification of remnants. We have evaluated an immunoseparation assay developed to measure cholesterol in remnant-like particles (RLP-C). This method uses monoclonal antibodies to human apolipoproteins B-100 and A-I ...

While plasma membrane cholesterol-rich microdomains play a role in cholesterol trafficking, little is known about the appearance and dynamics of cholesterol through these domains in living cells. The fluorescent cholesterol analog 6-dansyl-cholestanol (DChol), its biochemical fractionation, and confocal imaging of L-cell fibroblasts contributed the following new insights: i) fluorescence proper...

conclusions it seems that applying prp is an effective therapeutic approach for wound healing, and faster wound healing is expected due to the presence of more platelets and growth factors. results at the end of study, the prp group showed a greater reduction in the edema ecchymosed discharge approximation (reeda) score compared to the control group (85.5% reduction in the prp group; 72% in the...

background platelet rich plasma is known for its hemostatic, adhesive and healing properties in view of the multiple growth factors released from the platelets to the site of wound. the primary objective of this study was to use autologous platelet rich plasma (prp) in wound beds for anchorage of skin grafts instead of conventional methods like sutures, staplers or glue. methods in a single cen...
