Coupling of racemic N-protected amino acids with amino components by means of 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) in the presence of chiral tertiary amines such as strychnine, brucine, and sparteine proceeds enantioselectively, affording appropriate amides or dipeptides in 69-85% yield. The configuration of the preferred enantiomer and enantiomeric enrichment depend on the structures o...

The millimeter-wave rotational spectrum of the free 2’?SiC radical in the X 311 ground state, produced in a low-pressure glow discharge through SiH, and CO, was detected with the same reactive-molecule spectrometer used earlier to detect Sic and Si13C. Eleven rotational transitions, all but two with resolved hyperfine structure, were measured between 195 GHz (J = 4+ 5) and 372 GHz (J = 8 --+ 9)...

Objective(s) Sickle cell disease is a genetic disorder characterized by chronic haemolytic anaemia. Haemoglobin S containing red blood cells may be susceptible to oxidative stress due to imbalance between production of reactive oxygen species and the countering effect of the various antioxidants present in the body. Materials and Methods We evaluated some antioxidant enzymes which include gl...

Currently, biological method has been utilized in the treatment of wastewater -containing synthetic dyes used by textile industries in Iraq. The present work was devoted to study the operating feasibility using reverse osmosis (RO) and nanofiltration (NF) membrane systems as an alternative treatment method of wastewater discharged from Iraqi textile mills. Acid red, reactive black and reactive ...

PURPOSE To report three cases of posterior vasculitis associated with subacute giant cell arteritis (GCA). METHODS Three patients with decreased vision underwent complete ophthalmologic examination and fluorescein angiography. RESULTS All patients presented posterior vasculitis. Patient 1 had an erythrocyte sedimentation rate (ESR) of 38 mm/hr and a C-reactive protein (CRP) of 28mg/L. Patie...

A cellulose biopolymer was doped with Fe and Al forming a mesoporous composite. The composite showed excellent adsorption capacities of 117.86 mg g −1 95.62 for Reactive red 21 blue 19 respectively.

PURPOSE To investigate expression, regulation, potential role and targets of miR-195 and miR-497 in breast cancer. EXPERIMENTAL DESIGN The expression patterns of miR-195 and miR-497 were initially examined in breast cancer tissues and cell lines by Northern blotting and quantitative real-time PCR. Combined bisulfite restriction analysis and bisulfite sequencing were carried out to study the D...

The objective of this project was to biologically renovate reactive dyebaths and reuse the high-salt containing mixture in the dyeing process. This approach accomplishes two goals: (a) elimination of the color from the plant effluent; and (b) reuse of the renovated process water and salts, thus leading to final wastewater volume reduction, and water, as well as salt conservation. Nine commercia...
