Concentrations of 6 organophosphate esters(OPEs)were determined in 60 indoor(ID)and outdoor(OD)dust samples collected from 20 homes from Basrah,*** each home,two ID samples were collected,one from elevated surfaces(ESD)and one from the floor(FD)of the living room;while the OD samples were collected from the front yard of the same *** S6OPEs concentrations in dust samples ranged between 681 and 17900 ng/g with median concentrations of 5950,3590 and 1550 ng/g in ESD,FD and OD samples,*** OPEs were the most abundant compounds,contributing mean percentages of 88%,85%and 78%toΣ_(6)OPEs in ESD,FD and OD,respectively,with tris(1-chloro-2-propyl)phosphate(TCIPP)*** of our target OPEs in ESD significantly exceeded those in FD(p<0.05)for tris(2-chloroethyl)phosphate(TCEP)and tris(1,3-dichloro-2-propyl)phosphate(TDCIPP).Ratios of median concentrations of OPEs in ID:OD ranged from 1.5 for tri-n-butyl phosphate(TNBP)to 8.0 for TCEP,indicating the significance of indoor *** of chlorinated OPEs in ID were moderately correlated(R=0.522-0.591,P<0.05)with those in OD samples,suggesting interchange of OPEs between the two *** of OPEs in OD from houses with a contiguous front yard car porch exceeded those in OD from houses without a car porch and were significantly higher(P<0.05)for TCEP,TCIPP and 2-ethylhexyl diphenyl phosphate(EHDPP).Emissions from parked cars and the associated home are likely sources of OPEs in the OD *** on the concentrations reported here,the estimated daily intake(EDI)for the Iraqi population through house dust ingestion are all well below the relevant reference dose(RfD)values.

引用

Crystal Structure Theory and Applications 2013年第1期2卷 8-15页

作者： Ikram Dhouib salih Al-Juaid Tahar Mhiri Zakaria Elaoud Chemistry Department Faculty of Science King Abdulaziz University Jeddah KSA Laboratoire de l’Etat Solide Département de Chimie Faculté des Sciences de Sfax Sfax Tunisia

Single crystals of the tetraethylammonium dihydrogenmonophosphate bis trihydrogenmonophosphate [CH3CH2]4N+(H2PO4)(H3PO4)2(TEP), were grown by slow evaporation solution technique at room temperature. The compound was characterised by IR, Raman, differential thermal analysis (TG-DTA) and single crystal X-ray diffraction. It crystallizes in the monoclinic system (space group P21/c) with the following unit cell dimensions: a = 7.765 (2) , b = 16.531 (4) , c = 14.843 (2) , β = 100.99 (2)o, Z=4 , DX =1.67Mg.m-3, Dm=1.532Mg-3, λ (MoKa) = 0.71073 , u=0.384 mm-1, F(000)=991, T = 20 (2)o. The structure was solved by the direct method and refined to final R value of 0.0342 and Rw=0.107 for 3239 independent [(CH3CH2)4N]+ reflections. The structure consists of infinite parallel two-dimensional planes built of mutually , H3PO4 tetrahedra ?and cations connected by strong and hydrogen bonding. There are no contacts other than van der Waals interactions between the layers.

Ischemic colitis induced by the newly reformulated multicomponent weight-loss supplement Hydroxycut~

引用

World Journal of Gastrointestinal Endoscopy 2013年第4期5卷 180-185页

作者： Muhammed Sherid salih Samo Samian Sulaiman Joseph H Gaziano Department of Internal Medicine Division of Gastroenterology CGH Medical Center Department of Internal Medicine Division of Gastroenterology Saint Francis Hospital

Ischemic colitis accounts for 6%-18% of causes of acute lower gastrointestinal bleeding. It is more often multifactorial and more common in elderly. Drugs are considered important causative agents of this disease with different mechanisms. In this paper, we describe a 37-year-old otherwise healthy female presented with sudden onset diffuse abdominal pain and bloody stool. Radiologic, colonoscopic and histopathologic findings were all consistent with ischemic colitis. Her only suspected factor was hydroxycut which she had been taking for a period of 1 mo prior to her presentation. Her condition improved uneventfully after cessation of hydroxycut, bowel rest, intravenous hydration, and antibiotics. This is a first case of ischemic colitis with clear relationship with hydroxycut use (Naranjo score of 7). Our case demonstrates the importance of questioning patients regarding the usage of dietary supplements; especially since many patients consider them safe anddo not disclose their use voluntarily to their physicians. Hydroxycut has to be considered as a potential trigger for otherwise unexplained ischemic colitis.

Influence of Metal Ions on Hydrogen Production by Photosynthetic Bacteria Grown in Escherichia coli Pre-Fermented Cheese Whey

引用

Journal of Environmental Protection 2010年第4期1卷 426-430页

作者： Fadhil M. salih Muthana I. Maleek 不详

The photosynthetic bacteria, Rodospirillum rubrum, produced hydrogen when grown in cheese whey in presence of light. The production increased three times as much when whey was used after being incubated in presence of Escherichia coli at 37℃ for 5 days, giving a total of 3600 ml of H2 in 10 days. The presence of Fe ions (5 mg/L) enhanced H2 production of treated whey to about 6000 ml in 10 days. Mo ions (0.3 and 1.6 mg/l) did not affect achieved H2 production of treated whey. However, when Fe and Mo ions were present together, the production was comparable with that of Mo ions alone, i.e. Mo prevented Fe of producing any enhancing effect. The addition of Mn ions (7.68 mg/L) to treated whey containing Fe (5 mg/L) and Mo ions (8 mg/L) increased H2 production to give about 9500 ml/10 days.

Hand bone mass in rheumatoid arthritis:A review of the literature

作者： Gamze Kilic salih Ozgocmen Division of Rheumatology Department of Physical Medicine and RehabilitationErciyes UniversitySchool of MedicineGevher Nesibe Hospital

Rheumatoid arthritis(RA) is a common chronic inflammatory disease and periarticular osteoporosis or osteopenia of the inflamed hand joints is an early feature of RA Quantitative measurement of hand bone loss may be an outcome measure for the detection of joint destruction and disease progression in early RA. This systematic review examines the published literature reporting hand bone mass in patients with RA, particularly those using the dual X-ray absorptiometry(DXA) methods The majority of the studies reported that hand bone loss is associated with disease activity, functional statusand radiological progression in early RA. Quantitative measurement of hand bone mineral density by DXA may be a useful and practical outcome measure in RA and may be predictive for radiographic progression or functional status in patients with early RA.
