This paper reports on the effect of ageing by free-burning arcs in 7.5% C5-fluoroketone (C5-FK) with 92.5% technical air comparison to that (80% N2, 20% O2) at 1.3bar absolute pressure. The gases are aged applying a series dissipating an accumulated energy around 315kJ. It is found arc voltages and C5-FK same range do not vary significantly as function or current amplitude (∼40-900 A). Contact ...

In this paper, the attenuation coefficients of X-rays for a range voltages (20-35) kV were studied copper-based alloys (Cu + 0.05 AL 0.03 Ti) according to order (A1,A2,A3,A4,A5),by adding percentages silver (X=1,2,3,4,5)% with two particle sizes (Nano) and (Micro) alloy ( Cu92-x +5%Al +3%Ti+ Ag x) orders (B1,B2,B3,B4,B5) (C1,C2,C3,C4,C5) All sintered at (9000C) period (4) hours.The results show...

STUDY DESIGN Retrospective study. OBJECTIVES To evaluate the efficacy of bilateral C4-5 foraminotomy in preventing occurrence of postoperative C5 palsy and to identify possible risk factors for its development. METHODS A total of 70 consecutive patients who underwent open-door laminoplasty with bilateral C4-5 foraminotomy were included. Clinical, radiographic, and operative data was reviewe...

BACKGROUND & AIMS Complement activation plays an important role in the local pathogenesis of ischemia/reperfusion (I/R) injury. We investigated the action of anti-C5 monoclonal antibody (mAb) on local and remote organ injuries after intestinal I/R in the rat. METHODS Under anesthesia, functional anti-rat C5 mAb (18A), an isotype-matched control anti-C5 mAb (16C), or vehicle (phosphate-buffere...

The relative inflammatory roles of neutrophils, selectins, and terminal complement components are investigated in this study of skeletal muscle reperfusion injury. Mice underwent 2 h of hindlimb ischemia followed by 3 h of reperfusion. The role of neutrophils was defined by immunodepletion, which reduced injury by 38%, as did anti-selectin therapy with recombinant soluble P-selectin glycoprotei...

The adult respiratory distress syndrome is characterized by arterial hypoxemia as a result of increased alveolar capillary permeability to serum proteins in the setting of normal capillary hydrostatic pressures. Because bacterial sepsis is prominent among the various diverse conditions associated with altered alveolar capillary permeability, we studied the effect of bacteremia with attendant co...

PURPOSE To investigate the association of C5 SNPs with proliferative diabetic retinopathy (PDR) of type 2 diabetes (T2D). METHODS A total of four C5 SNPs including rs2269067, rs7040033, rs1017119 and rs7027797 were genotyped in 400 PDR patients with T2D (cases) and 600 non- proliferative diabetic retinopathy PDR (NPDR) with T2D patients (controls) by using PCR-RFLP method. mRNA expression was...

Complement components C3, C4, and C5 are members of the thioester-containing alpha-macroglobulin protein superfamily. Within this superfamily, a unique feature of the complement proteins is a 150-residue-long C-terminal extension of their alpha-subunits that harbors three internal disulfide bonds. Previous reports have suggested that this is an independent structural module, homologous to modul...

We report that photo-excitation of one-electron-oxidized adenine [A(-H)*] in dAdo and its 2'-deoxyribonucleotides leads to formation of deoxyribose sugar radicals in remarkably high yields. Illumination of A(-H)* in dAdo, 3'-dAMP and 5'-dAMP in aqueous glasses at 143 K leads to 80-100% conversion to sugar radicals at C5' and C3'. The position of the phosphate in 5'- and 3'-dAMP is observed to d...
