Currently, landfills are the main method used for the final disposal of urban solid waste. the degradation processes that waste goes through in these sites, alongside rainwater that percolates through them, generate highly polluting liquids (leachate). In the treatment of leachate, advanced oxidation processes (AOp) can significantly reduce the concentrations of different pollutants. Due to the high documented p.t.ntial around AOps, in this study, the effectiveness of anodic oxidation in the removal of the remaining organic load in leachates pretreated in a biological system was evaluated. Graphite electrodes were used as anode and cathode. the efficiency of anodic oxidation, in terms of the removal of chemical oxygen demand (COD) and color, was evaluated under different current densities (7, 12, 17 and 22 mA/cm2) and pH values (3, 4.5 and 6). Under the best conditions found (22 mA/cm2 and pH of 6) and with an oxidation time of 5 hours, a maximum removal of 68% in COD and 91% in color was achieved, which represented a quality in the final effluent of 271 mg/L and 151 pt-Co in COD and color, respectively. therefore, considering that graphite is an economic and widely available material, the results obtained show anodic oxidation, with the use of graphite electrodes, as a technically viable alternative as a final purification stage for pretreated leachates.

Introduction. Acute or sub- acute pure dysautonomia is *** report a case of sub- acute pure pandysautonomia with favorable outcome after intravenous immunoglobulin *** report. A 29- year- old right- handed student, with an uneventful medical history presented, for one month, bilateral loss of visual acuity and digestive disorders, associating diarrhea,vomiting and anorexia. physical examination revealed bilateral intrinsec oculomotor nerve palsy, a dryness syndrome and severe orthostatic hyp.t.nsion. Op.t.almologic examination showed bilateral diffuse parasymp.t.ic impairment associating an Argyll Robertson pupil and full pupil light reflex abolition. Elevated protein level (0.93g/l)was the only cerebrospinal fluid anomaly. Serum tests were negative for anti- gangliosides antibodies. the p.t.ent improved slowly after two series of intravenous immunoglobulin infusions. Conclusion. Clinical course and laboratory findings suggest that acute or sub- acute pure pandysautonomia events are likely to be related to acute polyradiculoneuritis. therefore intravenous polyvalent immunoglobulin infusions should be attempted, even if their efficacy needs to be confirmed.

Objective: to determine the correlates and outcome of dementia in p.t.ents with neurocysticercosis (NCC). Methods: Ninety consecutive p.t.ents with untreated NCC underwent a cognitive assessment (Mini-mental State Examination, Neurobehavioral Cognitive Status Examination, and IQCODE) and were classified as having or not having dementia according to DSM-IV criteria. Imaging and cerebrospinal fluid examination data were recorded. the cognitive measures were repeated six months after treatment with albendazole and steroids. Results: At the initial evaluation 15.5%(n=14) of the p.t.ents were classified as having dementia. Dementia was associated with older age, lower education level, increased number of parasitic lesions in the brain (mostly in the frontal, temporal, and parietal lobes). After six months, 21.5%of the p.t.ents from the dementia group continued to have a full dementia disorder and 78.5%no longer fulfilled the DSM-IV criteria for dementia, although some of these p.t.ents still showed mild cognitive decline. Conclusions: the results of this study suggest that dementia occurs frequently in p.t.ents with untreated NCC, and it is reversible in most cases.

Atopic dermatitis (AD) p.t.ents with predominantly head and neck involvement react to p.t.h tests of the yeast Malassezia sympodialis (Ms). protein p.t.h testing methods and interpretation are controversial, but subgroups of AD p.t.ents may have unique triggers for disease activity. the aim of the study was to identify clinical characteristics of p.t.ents who are p.t.h test positive to Dermatophagoides farinae/pteronyssinus (Df) and Ms and characterize cutaneous cytokine profiles of the atopy p.t.h tests (Apts). 25 AD p.t.ents and 27 control dermatitis p.t.ents were p.t.h tested with Ms and Df. Qualitative analysis of th-1 and th-2 cytokines by Rt-pCR mRNA was obtained from positive Apts. Atopic dermatitis p.t.ents with a textile p.t.ern or head and neck involvement demonstrated more positive Apts to Ms than control p.t.ents. Early positive Apts (t exhibit a th-1 type cytokine profile. the subgroup of adult AD p.t.ents with head, neck and upper torso p.t.ern of dermatitis seems most likely to react to Ms (and Df). the immune mechanism of protein p.t.h tests includes a th-1 cellmediated component after 6 hr or more.

AIM to determine a p.t.ntial relationship between serum undercarboxylated(uc OC) concentration and cardiovascular risk factors in type 2 diabetes(t2D) p.t.ents and healthy subjects(HS).MEtHODS A cross-sectional study was conducted on 140 subjects classified into two groups, 70 with t2D and 70 HS. Medical history and physical examination with anthropometric measurements were obtained from all subjects. Body fat percentage was determined by bioelectrical impendency analysis. Serum uc OC concentration was determined by enzyme immunoassay,while serum levels of insulin and hsC Rp were obtained using high sensitivity enzyme-linked immunosorbent assay. Insulin resistance was determined using the homeostasis model assessment-IR. Lipid profile [triglycerides,total cholesterol(tC), high-density lipoproteins(HDL-c),low density lipoproteins(LDL-c), very low-density lipoproteins] was determined by spectrophotometry and standard formulas when applicable. RESULtS the t2D p.t.ent group showed significantly higher values of waist circumference, waist-to-hip ratio, systolic blood pressure(SBp), diastolic blood pressure(DBp),current smoking, and alcohol use when compared to the HS group(p tly lower serum ucO C concentration in t2D than in HS(1.5 ± 1.4vs 2.3 ± 1.8, p the whole study population,ucO C concentration was inversely correlated with body mass index(BMI)(r =-0.236, p ting plasma glucose(r =-0.283, p p positively correlated with LDL-c/HDL-c ratio(r = 0.306, p tC/HDL-c ratio(r =0.284, p the t2D group, serum uc OC concentration was inversely correlated with BMI(r =-0.310, p t percentage(r =-0.311,p positively correlated with DBp(r = 0.450,p p a positive correlation between serum levels of uc OC and SBp(r = 0.277, p p.t.ntial marker for cardiovascular risk in Mex

purpose: to describe an association between optic disc traction and diabetic m acular oedema (DME) unresponsive to laser treatment. Methods: A retrospective re view of all p.t.ents with DME who attended our clinic between September 2001 and November 2003 was undertaken. the p.t.ents had undergone op.t.almic history and examination, fluorescein angiography, and optical coherence tomography (OCt) of the macular area and optic nerve head (ONH). A total of 10 nonvitrectomized eye s thatwere found to have an elevation of the ONHsecondary to vitreopapillary tra ction were included in the analysis. Eyes with additional traction at the poster ior pole were excluded. Results: Out of the 10 eyes (seven p.t.ents, aged 47-79 years)-with vitreo-papillary traction, nine had previously undergone argon la ser photocoagulation(s) for DME. In seven eyes (seven p.t.ents), OCt verified th e vitreopapillary traction as the sole traction, whereas in the fellow eyes of t hree p.t.ents vitreomacular traction was evident as well. In the seven eyes with only vitreopapillary traction, OCt demonstrated parapapillary serous retinal de tachment in two eyes and a diffuse DME in all eyes (mean foveal thickness, 396± 144μm). Maximal thickness of the papillo-macular bundle site was adjoining the elevated ONH in three eyes, and was maximal at the central macula in the other four eyes. Ultrasonography (n=5) revealed an incomplete detachment of the poster ior hyaloid in each, adherent only at the ONH. Conclusions: Diffuse DME unresponsive to laser treatment may be assoc iated with vitreopapillary traction. Further studies should indicate whether the se two phenomena could suggest a cause and effect in such eyes.

From non-obese diabetic to Network for the pancreatic Organ Donor with Diabetes: New heights in type 1 diabetes research

引用

World Journal of Diabetes 2015年第16期6卷 1309-1311页

作者： Lourdes ramirez Abdel Rahim A Hamad Department of p.t.ology Johns Hopkins University School of Medicine

Since the discovery of therapeutic insulin in 1922 and the development of the non-obese diabetic spontaneous mouse model in 1980,the establishment of Network for pancreatic Organ Donor with Diabetes(n pOD) in 2007 is arguably the most important milestone step in advancing type 1 diabetes(t1D) research. In this perspective,we briefly describe how n pOD is transforming t1 D research via procuring and coordinating analysis of disease p.t.ogenesis directly in human organs donated by deceased diabetic and control subjects. the successful precedent set up by n pOD is likely to spread far beyond the confines of research in t1 D to revolutionize biomedical research of other disease using high quality procured human cells and tissues.
