Open Journal of Emergency Medicine 2017年第2期5卷 43-74页

作者： Adonis Magoumou Narcisse Dabiré Yassir El Andaloussi Said Abdallah Amine Belmoubarik Rachid Ait-Mouha Karim Ahed nabil Omari Ahmed Reda Haddoun Driss Bennouna Mohamed Moujtahid Mohamed Nechad Mustapha Fadili Department of Orthopedic Traumatology Wing 4 Chu Ibn Rochd Casablanca Morocco

Background: We report a retrospective study of 47 total prosthesis of hip put in place among the young adult of less than fifty years in the service of Traumatology and Orthopedics at the Wing IV of the CHU Ibn Rochd of Casablanca, over a period from January 2008 to March 2014, with an average rate of decline of 42 months. Results: The deliberate group of 43 patients (47 hips including 4 bilateral) consisted of 26 women, either 60, 47% and 17 men, either 39, 53%. The average age of our patients was 36 years. In our series, the predominant etiology has been conducted for the indication of the hip replacement was the aseptic osteonecrosis of the femoral head which has represented 31.91%. With regards to the choice of implants, 85% of PTH were non-cemented, the cemented PTH has been used in 15% of cases. The Friction Torque metal/polyethylene was used in all cases. The functional outcome was appreciated by the rating of Merle of Aubigne before and after arthroplasty. The average rate of decline of 42 months, and the results were generally satisfactory. They were excellent in 27.78% of cases, very good in 19.44% of cases and good in 44.44% of cases. The results on the Pain were remarkable: the rating of the pain going 2.8 in pre-operative at 5.6 at the latest decline. The results on the walking and mobility were also good. It was noted as a complication: 4 cases of prosthetic dislocation, 1 case of aseptic descellement bipolar, 2 cases of early sepsis on hardware, 3 cases of paralysis of the sciatic external popliteal and 4 cases of periprothetiques ossification. In total, 5 total prosthesis of hip were occasions. The young age does not seem to be an obstacle to the prosthetic surgery. Conclusion: However, a major question remains concerning the distant future of these prostheses in young active subjects, because they will be submitted for many years in a job which can cause the descellement of prosthetic parts.

The aim of this prospective observational pilot study was to observe the impact of orbital atherectomy (OA) on the coronary microcirculation via coronary flow reserve (CFR) measurements. Fifteen subjects who had successful OA and stent placement with no procedural complication were enrolled at 3 hospitals in the U.S. Baseline and hyperemic velocities were 16 ± 5.2 and 36 ± 14 cm/sec, respectively. The average CFR post-procedure was within the normal range at 2.23 ± 0.33. The observation of normal CFR following OA may be attributed to the orbital action of the device that allows for continuous flow during treatment, minimizing a bolus embolization effect which can impact microvascular function.

Surgical Science 2014年第8期5卷 354-362页

HER-2/neu over expression is associated with increased tumor aggressiveness, increased rates of recurrence, and increased mortality in node positive patients. It is amplified and/or over expressed in approximately 30% of female breast cancers. This study was to detect the relation between HER-2/neu over expression and steroid hormone receptor status. It was conducted at Cairo and Bani Suif university hospitals between February 2012 to February 2014. HER-2/neu over expression was found to be positive in thirteen patients (41%) out of the thirty two patients included in the study, more positive (52%) HER-2/neu was found among estrogen receptor (ER) positive patients, on the other hand, only 18% positive HER-2/neu was detected among ER negative patients. This difference was statistically significant (P < 0.03). The same outcome was with progesterone receptors (PR) and HER-2/neu with statistically significant difference also (P = 0.02). Conclusion: HER-2/neu over expression is strongly related to ER and PR, this was more evident in negative steroid receptors status. The failure of treatment in positive steroid receptors could be explained by HER-2/neu positivity.

Ethanol-induced hepatic autophagy: Friend or foe?

引用

World Journal of Hepatology 2015年第9期7卷 1154-1156页

作者： nabil Eid Yuko Ito Yoshinori Otsuki Department of Anatomy and Cell Biology Division of Life Sciences Osaka Medical College

Excessive alcohol intake may induce hepatic apoptosis, steatosis, fibrosis, cirrhosis and even cancer. Ethanolinduced activation of general or selective autophagy as mitophagy or lipophagy in hepatocytes is generally considered a prosurvival mechanism. On the other side of the coin, upregulation of autophagy in nonhepatocytes as stellate cells may stimulate fibrogenesis and subsequently induce detrimental effects on the liver. The autophagic response of other non-hepatocytes as macrophages and endothelial cells is unknown yet and needs to be investigated as these cells play important roles in ethanol-induced hepatic steatosis and damage. Selective pharmacological stimulation of autophagy in hepatocytes may be of therapeutic importance in alcoholic liver disease.

Open Journal of Medical Imaging 2014年第3期4卷 103-107页

作者： Taha Kamel Alloush Mahmoud Haroun Ibrahim Nahed Salah El-Dein Ahmed Ghada Samir El-Shahed Lobna M. El-nabil El-Sayed Mohamed Hamdy Ibrahim Hosam Ahmed Azmy Faculty of Medicine Ain Shams University Cairo Egypt Ministry of Health Cairo Egypt

Objectives: To assess the impact of heart failure diseases on stroke severity and short term (1 month mortality). Materials and Methods: Totally, 200 patients admitted to Ain Shams university specialized hospital, were diagnosed clinically to have acute ischemic stroke within 3 days. History taking about previous heart disease was taken, and full general and neurological examinations were done. Full metabolic profile, cardiac examination and investigations were done. Carotid duplex, MRI stroke protocol and lastly clinical reevaluation using NIH Stroke Scale (NIHSS) after 1 month from stroke onset were done. Results: Patients with systolic dysfunction (EF ≤ 40%) had lacunar infarction in 18.75% of cases, partial anterior circulation infarction in 62.5% of cases, posterior circulation infarction in 6.25% of cases and total anterior circulation infarction in 12.5% of cases. Leucoaraiosis was present in 87% of cases and significant intracranial vessel stenosis was showed in 87.5% who had done MRI. Their median NIHSS score at admission was 10.5 with IQR of 5 - 21 and at follow-up it was 5 with IQR of 2.5 - 10.5. At follow-up 22.7% (5 patients) were dead. Conclusion: Systolic dysfunction (EF < 40) i.e. heart failure has no significant effect on stroke severity and 1 month follow up prognosis.

研究了在总钠量不变的条件下预水解甘蔗渣用含量不同的硫化钠、亚硫酸钠和硫化钠一亚硫酸钠混合物的碱性蒸煮液蒸煮和这些不同的处理方法对浆粕得率、蒸解度、漂率、化学和物理性能及浆粕黄化反应性能的影响。在硫酸盐蒸煮的情况下用另一批和不同方法除髓的蔗渣,制得的浆粕特性稍有不同,但两种蒸煮方法一般的结果是相同的。用碱性亚硫酸盐溶液蒸煮,当总钠中的30％为亚硫酸钠时,可得到最佳的结果。当用NaOH、硫化钠和亚硫酸钠混合物蒸煮时可成功地制得粘胶浆。这种蒸煮液可加快脱木素速度、降低聚合度(DP)和结晶度,并改善浆粕的反应性能。使用这种蒸煮液的主要缺点是浆粕得率较低。

Nitrate from the application of nitrogen-based fertilizers in intensive agriculture is a notorious waste product, though it lacks cost-effective solutions for its removal from potential drinking water resources. Catalytic reduction appears to be a promising technique for converting nitrates to benign nitrogen gas. Mesoporous silica SBA-15 is a frequently used catalyst support that has large surface areas and highly ordered nanopores. In this work, mesoporous silica SBA-15 bimetallic catalysts for nitrate reduction were investigated. The catalyst was optimized for the selection of promoter metal (Sn and Cu), noble metal (Pd and Pt) and loading ratios of these metals at different temperatures and reduction conditions. The catalysts prepared were characterized by FT-IR, N2 physisorption, XRD, SEM, and ICP. All catalysts showed the presence of cylindrical mesoporous channels and uniform pore structures that remained even after metals loading. In the presence of a CO2 buffer, the catalysts 4Pd-1Cu/SBA-15 and 1Pt-1Cu/SBA-15 reduced at 100?C under H2 and 1Pd-1Cu/SBA-15 reduced at 200°C under H2 demonstrated very high nitrate conversion. Furthermore, the forementioned Pd catalysts had higher N2 selectivity (88% - 87%) compared to Pt catalyst (80%). Nitrate conversion by the 4Pd-1Cu/SBA-15 catalyst was significantly decreased to 81% in the absence of CO2.
