Abstract: This is a retrospective case-control study conducted at Kassala hospital, eastern Sudan. Medical files of pregnant women with severe anaemia (haemoglobin (Hb) < 7 g/dl, n = 303) who delivered from January 2008 to December 2010 were reviewed. Socio-demographic and obstetric data were analysed and compared with a similar number of women with mild/moderate anaemia (Hb = 7-10.9 g/dl, n = 303) and with no anaemia (Hb > 11 g/dl, n = 303). Logistic regression analysis was performed separately for each of the outcome measures: preeclampsia, eclampsia, preterm birth, low birth weight (LBW) and stillbirth.There were 9578 deliveries at Kassala hospital, 4012 (41.8%) women had anaemia and 303 (3.2%) had severe anaemia. The corrected risk for preeclampsia increased only in severe anaemia (OR = 3.6, 95% CI: 1.4-9.1, P = 0.007). Compared with women with no anaemia, the risk of LBW was 2.5 times higher in women with mild/moderate anaemia (95% CI: 1.1-5.7), and 8.0 times higher in women with severe anaemia (95% CI: 3.8-16.0). The risk of preterm delivery increased significantly with the severity of anaemia (OR = 3.2 for women with mild/moderate anaemia and OR = 6.6 for women with severe anaemia, compared with women with no anaemia). The corrected risk for stillbirth increased only in severe anaemia (OR = 4.3, 95% CI: 1.9-9.1, P < 0.001).The greater the severity of the anaemia during pregnancy, the greater the risk of preeclampsia, preterm delivery, LBW and stillbirth. Preventive measures should be undertaken to decrease the prevalence of anaemia in pregnancy.Anaemia during pregnancy is a major public health problem, especially in developing countries [1]. It affects 41.8% of pregnant women globally, with the highest prevalence in Africa [2]. There is however significant variation in the prevalence of anaemia both within and between countries, necessitating a need for local data to help to improve preventive programmes. Anaemia during pregnancy, especially severe anaemia, is associat

BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-202
Abstract: Out of 646, 234 (36.2%) adults had anaemia; 68 (10.5%); 129 (20.0%) and 37 (5.7%) had mild, moderate and severe anaemia, respectively. In logistic regression analyses, age (OR?=?1.0, CI?=?0.9–1, P?=?0.7), rural vs. urban residency (OR?=?0.9, CI?=?0.7–1.3, P?=?0.9), female vs. male gender (OR?=?0.8, CI?=?0.6–1.1, P?=?0.3), educational level?≥?secondary level vs. < secondary level (OR?=?1.0, CI?=?0.6–1.6, P?=?0.8) and Hudandawa vs. non-Hudandawa ethnicity (OR?=?0.8, CI?=?0.6–1, P?=?0.1) were not associated with anaemia.There was a high prevalence of anaemia in this setting, anaemia affected adults regardless to their age, sex and educational level. Therefore, anaemia is needed to be screened for routinely and supplements have to be employed in this setting.Anaemia is a major public health problem, especially in developing countries [1]. It is common in adult and the prevalence of anaemia is increasing with advancing age [2]. There is however, a significant variation in prevalence of anaemia, both within and between countries, necessitating a need for local data for preventive measures. Anaemia is associated with adverse outcomes among adult such as reduced quality of life, depression, increased disability, higher risk of Alzheimer disease and increased risk of mortality [3,4]. Anaemia is a multifactorial condition and the increased heterogeneity in the distribution of social and biological factors with advancing age makes the epidemiology of anaemia a real challenge [5]. Epidemiology of anaemia is important for deciding the control strategies. Thus, studies investigating these parameters are vital and of great interest, so as to provide health planners and caregivers with fundamental guidelines for the implementation of preventive measures. Therefore, the aim of this work was to investigate the prevalence and predictors of anaemia among adults in Kassala, Eastern Sudan.This was a cross sectional community- based survey of adults (>15 year old) residents in Kassala, Ea

Abstract: Background Artemisinin-based combination therapy (ACT) is the treatment of choice for uncomplicated Plasmodium falciparum malaria in most areas of the world, where malaria is endemic, including Sudan. However, few published data are available on the use of ACT for treatment of P. vivax malaria. Methods This study was conducted at a health centre in Kassala, eastern Sudan, from October to December 2011. Patients with uncomplicated P. vivax malaria received artemether-lumefantrine (AL) tablets (containing 20mg artemether and 120 mg lumefantrine) and were monitored for 28 days. Results Out of the 43 cases enrolled in this study, 38 completed the 28-day follow-up. Their mean age was 25.1 years (SD: 1.5). On day 3 following AL treatment, all of the patients were afebrile and aparasitaemic. By day 28, all 38 patients exhibited adequate clinical and parasitological responses to AL treatment. The cure rate was 100% and 88.4% for the per protocol analysis andfor the intention to treat analysis, respectively. Mild adverse effects (nausea, vomiting, abdominal pain, dizziness and/or rash) that resolved spontaneously were observed in four (10.5%) of the patients. Conclusion AL combination therapy was fully effective for treatment of P. vivax malaria in the study in eastern Sudan. Trial registration Trial. Gov: NCT01625871
Review: Low Cost, Environmentally Friendly Humic Acid Coated Magnetite Nanoparticles (HA-MNP) and Its Application for the Remediation of Phosphate from Aqueous Media  [PDF]
Tadewos Damena, Tajeldin Alansi
Journal of Encapsulation and Adsorption Sciences (JEAS) , 2018, DOI: 10.4236/jeas.2018.84013
Abstract: Phosphate is a primary nutrient required for the normal functioning of many organisms in the ecosystem. However, presence of excess phosphate into the aquatic systems leads to eutrophication which can promote harmful algal growth and decrease the amount of dissolved oxygen in water. Municipal, industrial and agricultural run-off wastewaters are the major point sources for phosphate discharges. There are different methods to remove phosphates from water. Among these, adsorption is the most widely accepted method for phosphate removal because of its high efficiency, minimum cost, easy and simple operation and applicability at lower concentrations. The emphasis of this review, is to consolidate low cost, environmentally friendly humic acid coated magnetite nanoparticles (HA-MNP) and its application for the remediation of phosphate from aqueous media. The magnetic nanoparticles could be easily separated from the reaction mixture by using a simple hand held magnet and adsorption studies demonstrate the fast and effective separation of phosphate with maximum removal efficiency > 90% at pH 6.6. The adsorption behavior follows the Freundlich isotherm and the removal of phosphate is found higher at acidic and neutral pH compared to basic conditions. The nanoparticles exhibit good selectivity and adsorption efficiency for phosphate in the presence of co-existing ions such as Cl-, \"\"
Guar Gum as Corrosion Inhibitor for Carbon Steel in Sulfuric Acid Solutions
Portugaliae Electrochimica Acta , 2004,
Abstract: guar gum was tested as corrosion inhibitor for carbon steel in 1 m h2so4 solution using weight loss and tafel polarization techniques. the results showed that the inhibition efficiency increases with the increasing of the guar gum concentration, which act as an inhibitor of the mixed type. the inhibition action of guar gum was discussed in terms of its horizontal adsorption on the metal surface. the adsorption follows langmuir adsorption isotherm. the effect of the presence of chloride ion in pitting corrosion was analyzed by the potentiodynamic anodic polarization technique. the pitting corrosion potential changes with the concentration of cl- ion according to a sigmoid s-shaped curve. this behaviour was explained on the basis of the formation of passivatable, active and continuously propagated pits.

Aegilops has been considered a complex genus with as many as 22 species in Syria. The current study has used 585 nucleotides from 5.8S nuclear ribosomal DNA gene and internal transcribed spacer 2 for these different species. These data were aligned manually and subjected to bioinformatics manipulation in order to construct the genetic relationship among these species. Three statistical methods (maximum-parsimony-MP, maximum-likelihood-ML and neighborjoining-NJ) were used to execute the most likely relationship. The constructed genetic relationship showed homogeneinty in clustering of the species of the same plant type (A, B or C) with each other. A single NJ tree and a single ML tree were obtained with slight difference in topology within each plant type. Both trees disagreed with our previous finding in that A. searsii, speltoides and A. longissima clustered in one group and the first two species were sisters while A. caudata was out. Therefore, A. speltoides was not the oldest among them and these differences could be related to the difference in taxon sampling size. This study, however, supported our previous molecular finding and did not support the previous karyotypic study in that A.

Different Feeding Techniques of Microstrip Patch Antennas with Spiral Defected Ground Structure for Size Reduction and Ultra-Wide Band Operation  [PDF]

Journal of Electromagnetic Analysis and Applications (JEMAA) , 2012, DOI: 10.4236/jemaa.2012.410056
Abstract: Different feeding techniques of microstrip patch antennas with different spiral defected ground structures are presented in this paper. The investigated structures illustrate some merits in designing multi-electromagnetic band-gap structures by adjusting the capacitance and changing the inductance through varying the width and length of spiral defected ground structure. Then by applying the three different spirals shapes (one, two and four arms) as the ground plane of microstrip patch antenna with different feeding techniques to create multi or ultra wide-band, improve the antenna gain and reduce the antenna size, it is found that the four arms spiral defected ground structure of microstrip patch antenna with offset feed gives good performance, electrical size reduction to about 75% as compared to the original patch size and ultra-wide bandwidth extends from 2 GHz up to 12 GHz with ?8 dB impedance bandwidth.

International Journal of Analytical Chemistry , 2010, DOI: 10.1155/2010/704564
Abstract: Guaifenesin and dropropizine were analyzed through oxidation with periodic acid to give formaldehyde which was allowed to condense with 4-Amino-5-hydrazino-4H [1,2,4]-triazole-3-thiol (AHTT). The condensation product was further oxidized to yield a purple colored compound with maximum absorption at 550?nm. Beer's law was obeyed in the range of 5–45? g for guaifenesin and 10–80? g for dropropizine. Both drugs were also successfully determined in their dosage forms. 1. Introduction Guaifenesin (GF), 3-(2-Methoxyphenoxy)-1,2-propanediol; is reported to increase the volume and reduce the viscosity of tenacious sputum and is used as expectorant for productive cough [1]. Different methods have been reported for the analysis of GF including HPLC [2–8], GC [9, 10], capillary electrophoresis mass spectrometry [11], X-ray diffraction [12], voltammetry [13]. Dropropizine (DP), 3-(4-Phenyl-1-piperazinyl)-1,2-propanediol, is a cough suppressant reported to have a peripheral action in nonproductive cough [1]. Only two GC-mass spectrometry methods have been reported for the determination of DP in biological fluids [14, 15] in addition to a manufacturer procedure that involves the determination of dropropizine by measuring its UV absorbance at 237?nm in 0.05?N HCl (personal contact): Bromhexine HCl (BR), 2-Amino-3,5-dibromo-N-cyclohexyl-N-methylbenzylamine hydrochloride; N-(2-Amino-3,5-dibromobenzyl)-N-methylcyclohexylamine hydrochloride: The aim of the present paper is to develop a simple and accurate method for the determination of dropropizine and guaifenesin that permits their analysis in dosage forms without interference from excipients and other coformulated drugs. 2. Experimental 2.1. Chemicals and Reagents Purpald or 4-Amino-5-hydrazino-4H [ ]-triazole-3-thiol reagent (AHTT) (Sigma-Aldrich) was prepared as 0.5% in 0.5?M hydrochloric acid. Periodic acid (Winlab, UK.) was prepared as 1? solution in 0.2?M potassium hydroxide. HPLC grade acetonitrile was from Fisher Scientific, UK. Potassium dihydrogen phosphate was from Sigma-Aldrich Chemie, Germany. All other chemicals used were of analytical grade and water was freshly distilled. 2.2. Materials Reference standard guaifenesin (GF), dropropizine (DP) and bromhexine HCl (BR) were kindly supplied by Rameda Co. for pharmaceutical industries and diagnostic reagents, EVA Pharma for pharmaceutical and medical appliances and EVA Pharma for pharmaceutical and medical appliances, respectively. 2.3. Pharmaceutical Preparations Muclear Capsules: It is a product of Rameda Co., Batch No. 08455, claimed to contain 100?mg
