Baghdad, Iraq

Al-Mustansiriya University is a university in Baghdad, Iraq.The original Mustansiriya Madrasah, was established in 1227 by the Abbasid Caliph Al-Mustansir and was one of the oldest universities in the world. Its building, on the left bank of the Tigris River, survived the Mongol invasion of 1258 and has been restored.The modern Al-Mustansiriyah University was established with the help and financial support of the Republic of Ίrāq Teacher’s Union in 1963, mainly providing evening courses. In 1964, the University was given the status of a semi-state institution and some state financial support. At the same time it absorbed Al-Sha’ab University, another private university that had been founded by the Ίrāqi Association of Economists, and then moved to a new campus to the north of the city centre. Initially, the University also managed colleges in Mosul and Basra.In 1966 a law was passed under which the private universities were converted into public universities. Al-Mustansiriyah thus became, briefly, a College within the University of Baghdad. In 1967 a major reorganisation of higher education was initiated, with the intention that by 1969 all previous institutions would be abolished and reconstituted. Al-Mustansiriyah was designated as a separate University in 1968, and its branch campuses were detached to form part of the University of Mosul and the University of Basra. Wikipedia.

Objective: Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disease of the large intestine, usually involving the rectum. During the last decade, clinical trials have shown adalimumab (ADA) and infliximab (IFX) to be efficacious in inducing and maintaining remission for moderate to severe UC refractory to the conventional therapies. The purpose of this study was to compare the efficacy and safety of ADA and IFX for induction remission in Iraqi patients with moderately to severely active UC. Methods: A total of 50 patients with moderate to severe UC, who were refractory to concurrent treatment with oral corticosteroids and/or immune suppressants, were randomly assigned in 1:1 ratio to receive either ADA (160/80 mg, subcutaneous) or IFX (5 mg/kg, intravenous) during the induction phase (8 weeks). Primary efficacy endpoint was clinical remission at week 8. Secondary efficacy endpoints were the clinical response, mucosal healing, subscores indicative of mild disease (rectal bleeding subscore [RBS], physician’s global assessment [PGA] subscore, and stool frequency subscore [SFS]). Partial Mayo score was also evaluated in addition to the inflammatory bowel disease questionnaire (IBDQ). Additional subgroup analysis was based on the Mayo score, extensive colitis, concomitant medications, high sensitivity C-reactive protein (hs-CRP) level, and patient weight at baseline. The safety profile was assessed in all enrolled patients. Results: At week 8, 24% of patients receiving ADA were in clinical remission, compared with 28% on IFX (p>0.05). Clinical response was achieved in 48% of patients receiving ADA and 52% of patients on IFX (p>0.05). Mucosal healing was achieved in 40% of patients receiving either ADA or IFX (p>0.05). For the subscores indicative of mild disease (≤1), the patients % of RBS and PGA was significantly higher within IFX group (p<0.05) while the patients % of SFS was significantly higher within ADA group (p<0.05). The proportion of patients achieving clinical remission based on the partial Mayo score, in addition to IBDQ response index, was not differ significantly between the two groups from week 2 and throughout the study (p>0.05). The patients with higher Mayo score (≥10), higher hs-CRP (≥10 mg/L), and higher weight (≥70 kg) at baseline were associated with reduced remission rates. ADA and IFX treatment were generally well-tolerated and the overall safety profile matched. Conclusion: ADA and IFX were comparable in their effectiveness for inducing clinical remission and response in patients with moderate to severe UC. Both of the biologic agents were well tolerated with an approach safety profile. © 2017 The Authors.

Background: Observational studies indicate that higher vitamin C intake is associated with reduced risk for cardiovascular diseases. However, randomised controlled trials (RCT) examining the effect of vitamin C on endothelial function (EF) have reported inconsistent results. The aims of this systematic review and meta-analysis were to determine the effect of vitamin C supplementation on EF and to investigate whether the effect was influenced by health status, study duration, dose and route of vitamin C administration. Methods: We searched the Medline, Embase, Cochrane Library, and Scopus databases from inception to May 2013 for studies that met the following criteria: 1) RCT with adult participants, 2) vitamin C administered alone, 3) studies that quantified EF using commonly applied methods including ultrasound, plethysmography and pulse wave analysis. Results: Pooling the data from 44 clinical trials showed a significant positive effect of vitamin C on EF (SMD: 0.50, 95% CI: 0.34, 0.66, P<0.001). Stratification of the analysis by health outcome revealed improved EF in atherosclerotic (SMD: 0.84, 95% CI: 0.41, 1.26, P<0.001), diabetic (SMD: 0.52, 95% CI: 0.21, 0.82, P<0.001) and heart failure patients (SMD: 0.48, 95% CI: 0.08, 0.88, P<0.02) after vitamin C supplementation. The effect size appeared to be unaffected by study design, duration, baseline plasma vitamin C concentration or route of administration of vitamin C. The meta-regression showed a significant positive association between vitamin C dose and improvement in EF (β: 0.00011, 95% CI: 0.00001, 0.00021, P=0.03). Conclusions: Vitamin C supplementation improved EF. The effect of vitamin C supplementation appeared to be dependent on health status, with stronger effects in those at higher cardiovascular disease risk.

Capability of Rice Husk (RH) on the removal of four types of dyes pollutant from wastewater which were methylene blue, Congo red, brilliant green and crystal violent using different design parameters by adsorption process is focus on. The design parameters studied to adsorb above four dyes using RH as an adsorbent material were initial concentration of dye, absorbance material packing height which was RH, pH of dye solution feed inlet, treatment time, feed flow rate and feed temperature, these parameters were varied from (1-100) mg/l, (10-100) cm, (1-8), (1-60) min, (5-100) ml/min and (20-55°C) respectively. Results show that the higher removal efficiency was (95.81, 93.44, 96.62 and 96.35) % for brilliant green, Congo red, crystal violent and methylene blue dyes respectively from aquatic solution and these efficiencies were decreased with increasing of initial concentration and flow rate while the removal efficiencies increased with increasing absorbance material bed height and feeding temperature. The removal efficiency was increased with increasing pH of solution for methylene blue, brilliant green and crystal violent dyes and decreased with increasing pH of solution for Congo red dye. Statistical model is achieved to find an expression combined all operating parameters with the removal efficiency for dyes used in this paper in a general equation. By this way we can possess different benefits which are: remove the toxic dyes contaminated the water, get rid of agricultural waste RH.

An interdigitated extended gate field effect transistor (IEGFET) has been proposed as a modified pH sensor structure of an extended gate field effect transistor (EGFET). The reference electrode and the extended gate in the conventional device have been replaced by a single interdigitated extended gate. A metal–semiconductor-metal interdigitated extended gate containing two multi-finger Ni electrodes based on zinc oxide (ZnO) thin film as a pH-sensitive membrane. ZnO thin film was grown on a p-type Si (100) substrate by the sol–gel technique. The fabricated extended gate is connected to a commercial metal-oxide–semiconductor field-effect transistor device in CD4007UB. The experimental data show that this structure has real time and linear pH voltage and current sensitivities in a concentration range between pH 4 and 11. The voltage and current sensitivities are found to be about 22.4 mV/pH and 45 μA/pH, respectively. Reference electrode elimination makes the IEGFET device simple to fabricate, easy to carry out the measurements, needing a small volume of solution to test and suitable for disposable biosensor applications. Furthermore, this uncomplicated structure could be extended to fabricate multiple ions microsensors and lab-on-chip devices. © 2016 The Minerals, Metals & Materials Society

In this work, we have studied the effect of the gamma irradiation on the optical properties and optical constants of Polystyrene doped by methylene blue (mb) with thickness in the range 0.11 + 5 mm. The samples have been investigated via transmittance and reflectance spectra, and characterized in the wavelength range 300-900 nm. The optical band gap Eg was determined while the optical absorption spectra showed that the absorption mechanism is an indirect allowed transition, which found that optical energy gap E g decreases after irradiation. The optical constants (refractive index, extinction coefficient, and real and imaginary parts of the dielectric constant) showed clear changes with irradiation. The oscillator energy E o , dispersion energy E d and other parameters have been determined by the Wemple-DiDomenico method. The most significant result of the present study is to determine the optical constants and optical band gap of the film. © TÜBI·TAK.

The free -COOH present in NSAIDs is thought to be responsible for the GI irritation associated with all traditional NSAIDs. Exploitation of mutual prodrugs is an approach wherein the NSAID is covalently bounded to a second pharmacologically active carrier/drug with the ultimate aim of reducing the gastric irritation. In this study some NSAIDs were conjugated with gabapentin via ester bonds using glycol spacers with the expectation of reducing gastric adverse effects and obtaining synergistic analgesic effects. The kinetics of ester hydrolysis were studied in two different non enzymatic buffer solutions at pH 1.2 and 7.4, as well as in 80% human plasma using HPLC with chloroform -methanol as mobile phase. Compounds 9a-c with ethylene glycol spacers showed significant stability at buffer solutions with half lives ranging from about 8-25 h, while the underwent a reasonable plasma hydrolysis (49%-88%) in 2 h. Compound 9d with a propylene glycol spacer shows a higher rate of enzymatic hydrolysis than the corresponding ethylene glycol compound 9c. The result of compounds 9a-c indicate that these compounds may be stable during their passage through the GIT until reaching the blood circulation. © 2012 by the authors; licensee MDPI, Basel, Switzerland.

The theory of four-wave mixing (FWM) in the quantum dot (QD) semiconductor optical amplifiers (SOAs) is discussed by combining the Q Drate equations system, the quantum-mechanical density-matrix theory, and the pulse propagation in QD SOAs including the three region of QD structure ground state (GS), excited state (ES), and wetting layer. Also, relations for differential gain, gain integral, and nonlinear susceptibility of both pump, probe, and signal pulses were discussed. Gain and differential gain have been calculated for QD structure. FWM efficiency and its components [spectral hole burning (SHB), carrier heating, and carrier density pulsation] are calculated. It is found that inclusion of ES in the formulas and in the calculations is essential since it works as a carrier reservoir for GS. It is found that QD SOA with enough capture time from ES to GS will reduce the SHB component, and so it is suitable for telecommunication applications that require symmetric conversion and independent detuning. © 2013 Optical Society of America.

Several wars and a 13-year embargo as well as several years of civil war with the recent war on terrorism have cumulatively damaged Iraq's land, air, water, and health infrastructure. The sand particles in Iraq contain toxic substances, which dates back to the pollution caused by military actions that disassemble the desert sands and turn it into light dust. This dust reaches cities as dust storms that effect most Iraqi cities. The presence of depleted uranium (DU) in the Iraqi food chain is documented by measuring the uranium in animals organs in different Iraqi cities with the highest concentration in the south of Iraq. One of the major sites of pollution in Iraq is the Al-twaitha nuclear research site. The nuclear research reactors were destroyed in the 1991 Gulf War. Barrels containing radioactive materials and sources were stolen from the site in the 2003 war. This resulted in considerable radioactive pollution at the site and in its surrounding areas. Soil sample have been found to be contaminated by Cs-137and Co-60. Cancer and birth defects are most associated with the environmental pollution caused by the conflicts. All studies related to this by Iraqi researchers are discussed in this review. From studying the Iraqi scientific publications, we can conclude that Basrah, Baghdad, Faluja, Mosul and Thi-Qar are the most effected cities in Iraq. This review concludes that the presence of a heavily contaminated environment with war related pollutants in most of the Iraqi cities needs much attention and huge effort to reduce the related health problems. © 2016 by De Gruyter.
