Introduction: Tubular and interstitial nephropathy syndrome with uveitis or TINU syndrome is a rare association. Patients and methods: We have listed cases in which the clinical-biological picture and histology were consistent with this syndrome. Results: Two cases were retained: These were two female patients whose mean age at diagnosis was 16 years. The inaugural symptoms were bilateral anterior uveitis in two cases. The time to onset of renal signs: was 4 to 2 weeks months. Acute kidney failure was reported in both cases with a mean creatinine of 36.4 mg/l. An average proteinuria of 1.1 g/24 h associated with aseptic leukocyturia in one case/2 and glycosuria normoglycemic in 1 case/2. Non inflammatory syndrome specific with inflammatory anemia is reported in both cases. Kidney puncture biopsy confirmed the diagnosis with nephropathy diffuse polymorphic tubulointerstitial and immunofluorescence negative in both cases. Oral corticosteroid therapy (1 mg/kg per day) was started for 4 to 6 months. Both patients received initial local corticosteroid therapy for uveitis. The outcome was favorable under treatment with remission complete. Kidney function recovered after 6 months with an average serum creatinine of 6 mg/l. Discussion: The incidence of TINU syndrome appears to be underestimated in the literature. It is believed to be an autoimmune disease. The positive diagnosis is based on clinical, biological and histological. An etiological investigation in search of disease systemic is necessary before making the diagnosis. There is no codified treatment. The prognosis is favorable in the majority of cases. Conclusion: Investigation of renal function is necessary for any patient.

American Journal of Analytical Chemistry 2016年第5期7卷 469-477页

作者： Mona N. el Hazek Azza A. Gabr Nuclear Materials Authority El Maadi Cairo Egypt Chemistry Department Faculty of Science Jazan University Jazan Saudi Arabia Chemistry Department Faculty of Science Aswan University Aswan Egypt

Sedimentary rocks have been found to host several Mn minerals in addition to some economic metal values. Besides recoverable Al occurring as gibbsite mineral, the latter include Cu, Zn, Co, Ni, U as well as rare earth elements. In this work, the ore material was subjected to sulfuric acid leaching in the presence of oxalic acid as a reductant to maximize the extraction of Mn. The optimum leaching conditions to achieve almost complete leaching efficiency of Mn with Fe dissolution not exceeding 13% involved 0.5 M sulfuric acid and 0.25 M oxalic acid in a solid/liquid ratio of 1/15 at 85°C for 105 min using an ore size of -150 μm. The leaching behavior of the associated interesting metal values (Al, Cu and Zn) has also been investigated.

Aziz yasser el-Mohtaseb Andrology Department Faculty of Medicine Cairo University Cairo 12311 Egypt Medical Biochemistry Department Faculty of Medicine Cairo University Cairo 12311 Egypt Clinical Pathology Department Faculty of Medicine Cairo University Cairo 12311 Egypt

Aim： To assess laminin levels in the seminal plasma of infertile and fertile men, and to analyze the correlation of laminin levels with sperm count, age, sperm motility and semen volume. Methods： One hundred and twenty-five recruited men were equally divided into five groups according to their sperm concentration and clinical examination： fertile normozoospermia, oligoasthenozoospermia, non-obstructive azoospermia （NOA）, obstructive azoospermia （OA） and congenital bilateral absent vas deferens （CBAVD）. The patients＇ medical history was investigated and patients underwent clinical examination, conventional semen analysis and estimation of seminal plasma laminin by radioimmunoassay. Results： Seminal plasma laminin levels of successive groups were： 2.82 ± 0.62, 2.49 ± 0.44, 1.77 ± 0.56, 1.72 ± 0.76, 1.35 ± 0.63 U/mL, respectively. The fertile normozoospermic group showed the highest concentration compared to all infertile groups with significant differences compared to azoospermic groups （P 〈 0.05）. Testicular contribution was estimated to be approximately one-third of the seminal laminin. Seminal plasma laminin demonstrated significant correlation with sperm concentration （r = 0.460, P 〈 0.001） and nonsignificant correlation with age （r = 0.021, P = 0.940）, sperm motility percentage （r = 0.142, P = 0.615） and semen volume （r = 0.035, P = 0.087）. Conelusion： Seminal plasma laminin is derived mostly from prostatic and testicular portions and minimally from the seminal vesicle and vas deferens. Estimating seminal laminin alone is not conclusive in diagnosing different cases of male infertility.

The effect of nanosized CoFe2O4 addition on the magnetic properties of GdBa2Cu3O7-δ using AC magnetic susceptibility measurements

引用

Journal of Advanced Ceramics 2016年第1期5卷 93-101页

Superconductor samples of type (CoFe2O4)xGdBa2Cu3O7-δ (0≤x≤0.1) were synthesized by the conventional solid-state reaction technique, whereas nanosized CoFe2O4 was prepared by co-precipitation method with grain size of about 8.5 nm. The elemental content of the prepared samples was determined using particle induced X-ray emission (PIXE). The temperature dependence of real (χ') and imaginary (χʺ) components of AC magnetic susceptibility (ACMS) at different magnetic field amplitude (3–15 Oe) was investigated. The analysis of the temperature dependence of ACMS was performed using Bean critical state model. The values of the critical current density J c at T > T p (T p is the inter-granular loss peak temperature) were calculated as a function of magnetic field and nanosized CoFe2O4 content. It was found that the low nanosized CoFe2O4 addition content (x = 0.01) improves the critical current density J c of Gd-123 superconducting phase. The observed variation of J c with temperature indicated that the weak links are changed from superconductor–normal metal–superconductor (SNS) for free sample to superconductor–insulator–superconductor (SIS) type of junctions for samples added with nanosized CoFe2O4 of x > 0.01. We also discussed the experimental results in the framework of the critical state model to estimate the effective volume fraction of the grains f g using Cole–Cole plots.

Anemia in ESKD Patient (End-Stage Kidney Disease): The Rare Cause Is in the Forefront

引用

Open Journal of Nephrology 2022年第4期12卷 382-389页

作者： Awad Magbri Mariam el-Magbri Pablo Abrego Hernandez Marshfield Medical Center Weston USA

We reported a case of severe anemia in a patient with end-stage kidney disease (ESKD) on dialysis. The anemia developed when the patient is switched from hemodialysis (HD) to peritoneal dialysis (PD) when the intra-venous erythropoietin stimulating agent (ESA, Epogen) was changed into subcutaneous injection of darbepoetin. The patient’s hemoglobin dropped 2 grams in about two months during this period. Extensive work-up including, bleeding disorders, hemolysis, iron deficiency, infections including CMV, Epstein-Bar virus, parvo-19 virus infection were unrevealing The anti-Epogen neutralizing antibodies were not measured due to unavailability. Bone marrow biopsy and aspirate were negative for infiltrations or myelodysplastic syndrome (MDS). The leukocyte and platelet counts were normal. Even though anti-ESA antibodies were not measured in this case, all tentative causes of his anemia were excluded by laboratory investigations. The patient’s anemia was treated symptomatically with blood transfusion and discontinuation of the ESA treatment. He made a remarkable recovery.

A Study on the Effects of Traffic Information Error on Route Choice Behavior

A Study on the Effects of Traffic Information Error on Route...

作者： el Bachir DIOP 大连理工大学

学位级别：硕士

Advanced Traveler Information Systems help drivers reduce their travel time and delay by providing them with information on their available alternatives. Such systems have proven to be efficient for alleviating traffic congestion in situations where other measures such as demand abatement have shown their limitations. This would explain the increasing attention paid to such systems recently. However, the effectiveness of ATIS depends highly on drivers’ response to the information provided. Thus it is essential to understand drivers’ behavior under the influence of traffic information. Earlier modeling efforts were based on the assumption that the information is perfect and drivers comply with it without any thought about accuracy and reliability. Recent research established the relationship between drivers’ behavior and information accuracy but did not incorporate drivers’ compliance when the information is unreliable. This study proposes a new approach in modeling drivers’ behavior in response to traffic information error. The methodology used here takes into account the different steps of the decision making process by investigating drivers’ compliance with ATIS in case of inaccuracy and the subsequent route choice if they decide to rely on the predictions. Stated Preference method was used to collect data on drivers’ route choice under the influence of ATIS lack of accuracy. The survey design incorporates the factors affecting drivers’ perception of traffic information error. Drivers’ response was illustrated as a multidimensional decision making process with the driver’s compliance with ATIS in case of inaccuracy at the first level. The second level consists of the route choice if the driver complies with the information. Modeling such a process requires the estimation of the correlation between drivers’ compliance with ATIS and the subsequent route choice by the use of a nested structure.
