In this paper,authors reported the results of wastewater treatment of discharges from sanitary facilities and laboratories from de Metropolitan Autonomous University Azcapotzalco campus in Mexico city in a pilot plant integrated with a unit of coagulation-flocculation and sedimentation of suspended particulate and multilayer filtration with sand,zeolite and anthracite that filtered particulate higher than 5 nanometer of diameter as primary treatment and advanced oxidation based in the use of hydroxyl radical through ozonation and UV Photocatalysis with zinc oxide,zinc oxide doped with silver and zinc oxide doped with zirconia as fine films photocatalysts on a US 100 stainless steel wire as secondary treatment,and finally with activated carbon adsorption as final *** and ORP were evaluated after each step as representative of BOD stablished as MAC’s in Mexican regulation on wastewater effluents,obtaining values that comply with the regulation.

AIM: To study the effect of seminal plasma on Chemokine(C-C motif) ligand 20(CCL20) production by epithelial cells and its relationship with ***: HEC-1A cells, a cell line derived from a monostratified endocervical epithelium, were incubated with samples of seminal plasma(diluted 1:10 in culture medium) recovered from human immunodeficiency virus(HIV) seronegative(HIV-) or HIV seropositive(HIV+) subjects. Recombinant human interleukin 1 beta(IL-1β) was used as positive control, and culture medium only as negative control. The measurement of CCL20 production in the supernatants of HEC-1A cells and of lactoferrin in seminal plasma was determined by enzyme-linked immunosorbent assay techniques. A fractionation of seminal plasma proteins was performed by ion exchange chromatography on a pool of seminal plasma specimens from HIV- subjects. Each fraction was tested for its ability to stimulate the production of CCL20 by HEC-1A cells and for its lactoferrin concentration. The HIV viral load in seminal plasma samples from HIV+ patients was measured using the HIV-Monitor kit(Roche Diagnostic Systems, Branchburg, nJ, United States).RESULTS: The positive control IL-1β was responsible for an increase of 11.36 ± 3.36 times in the production of CCL20. Stimulation of HEC-1A cells was performed in 34 seminal plasma samples(22 from HIV+ subjects and 12 from HIV- subjects). The mean production of CCL20 by HEC-1A in presence of seminal plasma from HIV- and HIV+ subjects was respectively 5.38 ± 0.91 and 7.57 ± 3.26 times higher than that obtained with the untreated cells(P n the two groups). Using the same 34 specimens of seminal plasma, no correlation was observed between the concentration of total proteins in seminal plasma and their ability to stimulate the secretion of CCL20 by HEC-1 cells. In contrast, the ability to produce CCL20 by HEC-1A cells correlated to the concentration of lactoferrin in the seminal plasma samples(r coefficient = 0.56; CI: 0.26

Flame Thermal Spray (FTS) coatings frequently show some porosity and reduced adherence to substrate, which affect its properties, especially its corrosion resistance. In this work, the corrosion resistance of AISI 1018 carbon steel coated by different methods is compared: electroless nickel (En) coating, niCrFeBSi obtained by FTS, duplex coatings of an En deposit on a layer of niCrFeBSi obtained by FTS and a layer of niCrFeBSi on an En deposit. The coatings were characterized using optical microscopy and scanning electron microscopy techniques, EDS microprobe microanalysis, roughness as well as electrochemical polarization tests to obtain the corrosion rate. The results show the enhancement in the corrosion resistance in saline medium of the duplex coatings, especially of the En coating on FTS layer.

In addition to clinical risk markers, indices of left ventricular(LV) systolic function are valuable prognostic markers after acute myocardial infarction(MI). Previous studies have also suggested that LV diastolic function may contribute with prognostic information. The present study assessed whether this assumption applies to a large population of patients with acute MI who underwent thrombolyt ic therapy.520 out of 608 patients participating in the ATTenuation by Adenosine of Cardiac Complications (ATTACC) study, with an ST-elevation acute MI underwe nt two-dimensional and Doppler echocardiographic examination at 4 (range 2-10) days after admission. During the follow-up period of 31 (S.D.±11) months, car diovascular death occurred in 57 (11%) patients, nonfatal acute MI occurred in 77 (15%), and 124 (24%) patients suffered a combined cardiovascular end-point (either nonfatal acute MI or cardiovascular death). Univariate regression analy sis showed that all indices of LV systolic function predicted cardiovascular dea th and combined cardiovascular end-points. Regarding LV diastolic function only a restrictive filling pattern predicted cardiovascular death. In a multistep mu ltivariate regression analysis in which the variables were introduced in a hiera rchic order age, history of systemic hypertension, wall motion score index (WMSi ), and history of previous MI and diabetes mellitus were independent predictors of cardiovascular death. A history of systemic hypertension or congestive heart failure were independent predictors of nonfatal acute MI, while a history of sys temic hypertension, wall motion score index and diabetes mellitus independently predicted combined cardiovascular *** results of this study confirme d that clinical risk indicators and LV systolic function were the most important independent predictors of cardiovascular death and combined cardiovascular end -points. LV diastolic function assessed by Doppler-echocar-diography did not provid
