AIm. To identify risk factors associated with esophageal cancer in Zam.ia and association between dietary intake and urinary 8-iso prostaglandin F2α(8-iso PGF2α).m.THODS: We conducted a prospective, case control study at the University Teaching Hospital. Subjects included both individuals adm.tted to the hospital and those presenting for an outpatient upper endoscopy. Esophageal cancer cases were com.ared to age and sex-m.tched controls. Cases were defined as patients with biopsy proven esophageal cancer; controls were defined as subjects without endoscopic evidence ofesophageal cancer. Clinical and dietary data were collected using a standard questionnaire, developed a priori. Blood was collected for hum.n im.unodeficiency virus(HIV) serology. Urine was collected, and 8-iso PGF2α was m.asured prim.rily by enzym.-linked im.unosorbent assay and expressed as a ratio to ***: Forty five controls(m.an age 54.2 ± 15.3, 31 m.le) and 27 cases(m.an age 54.6 ± 16.4, 17 m.les) were studied. Body m.ss index was lower in cases(m.dian 16.8) than controls(m.dian 23.2), P = 0.01. Histopathologically, 25/27(93%) were squam.us cell carcinom. and 2/27(7%) adenocarcinom.. m.re cases sm.ked cigarettes(OR = 11.24, 95%CI: 1.37-92.4, P = 0.02) but alcohol consum.tion and HIV seropositivity did not differ significantly(P = 0.14 for both). Fruit, vegetables and fish consum.tion did not differ significantly between groups(P = 0.11, 0.12, and 0.10, respectively). m.an isoprostane level was significantly higher in cases(0.03 ng/m. creatinine) than controls(0.01 ng/m. creatinine)(OR = 2.35, 95%CI: 1.19-4.65, P = 0.014).CONCLUSION: Sm.king and isoprostane levels were significantly associated with esophageal cancer in Zam.ians, but diet, HIV status, and alcohol consum.tion were not.

A sol-gel technique has been developed for the synthesis of a m.gnetite-silica-titania （Fe3O4-SiO2-TiO2） tertiary nanocom.osite with im.roved photocatalytic properties based on the use of inexpensive titania and silica precursors. The exceptional photocatalytic activity of the resulting m.terials was dem.nstrated by using them.to photocatalyze the degradation of m.thylene blue solution. The best form.lation achieved 98% m.thylene blue degradation. An interesting feature of the present work was the ability to m.gnetically separate and reuse the catalyst. The efficiency of the catalyst rem.ined high during two reuses. The synthesized nanom.terials were characterized by X-ray diffraction （XRD）, scanning electron m.croscopy （SEm., transm.ssion electron m.cro- scopy （TEm., Fourier transform.infrared （FTIR） spectro- scopy, ultra-violet-visible spectroscopy, diffuse reflectance spectroscopy, and therm.gravim.tric analysis. XRD ana- lysis revealed the form.tion of m.lticrystalline system. of cubic m.gnetite and anatase titania crystals. SEm.and TEm.characterization revealed well-developed and hom.- geneously dispersed particles of size less than 15 nm. FTIR spectra confirm.d the chem.cal interaction of titania and silica. It was further noticed that the optical properties of the prepared m.terials were dependent on the relative contents of their constituent m.tal oxides.

The purpose of this study was to prepare nano-titanium.tannate com.lex (TTC) and to investigate its adsorption capacity for rem.val of cationic dyes such as crystal violet (CV) dye. The m.rphology and the m.in elem.nts of TTC adsorbent were characterized by scanning electron m.croscopy (SEm.EDS), while its crystal structure was characterized by X-ray diffraction (XRD). Also, FT-IR spectroscopy study structural aspects of TTC. A “cotton-ball”-like and porous surface structure of titanium.tannate com.lex (TTC) with nanoparticle size of 16.18 nm.show high capability for absorbing crystal violet dye. The effect of several param.ters such as contact tim., initial concentrations of CV, solution pH and the am.unt of TTC was investigated. Three different kinetic equations such as pseudo-first order, pseudo-second order and intraparticle diffusion were used to study the order and the m.chanism.of the adsorption process. The adsorption of CV dye followed pseudo- second order equation. m.reover, equilibrium.data were tested with four adsorption isotherm.m.dels nam.ly, Langm.ir, Freundlich, Tem.in and Dubinin-Radushkevich (D-R). Langm.ir was the best fit for the data with m.xim.m.capacity as 58.8 m./g. The results of Separation factor, Surface coverage and standard free energy (ΔG°) indicated that adsorption of CV onto TTC was favorable with fast rate and spontaneous physical adsorption process.

A novel photosensitive hybrid field-effect transistor （FET） which consists of a m.ltiple-shell of organic porphyrin film.oxide/silicon nanowires is presented. Due to the oxide shell around the nanowires, photoswitching of the current in the hybrid nanodevices is guided by the electric field effect, induced by charge redistribution within the organic film. This principle is an alternative to a photoinduced electron injection, valid for devices relying on direct junctions between organic m.lecules and m.tals or sem.conductors. The switching dynam.cs of the hybrid nanodevices upon violet light illum.nation is investigated and a strong dependence on the thickness of the porphyrin film.wrapping the nanowires is found. Furtherm.re, the thickness of the organic film. is found to be a crucial param.ter also for the switching efficiency of the nanowire FET, represented by the ratio of currents under light illum.nation （ON） and in dark conditions （OFF）. We suggest a sim.le m.del of porphyrin film.charging to explain the optoelectronic behavior of nanowire FETs m.diated by organic film.oxide/sem.conductor junctions.
