    Pyogenic liver abscess, which may lead to devastating consequences, is an uncommon medical problem in pediatrics and has generally been reported in compromised hosts. This article describes two patients with beta-thalassemia major and hemochromatosis complicated by Klebsiella pneumoniae liver abscess. One of the patients had severe complications, including subphrenic abscess, pleural effusion and meningitis. To present knowledge, the occurrence of K. pneumoniae liver abscess in patients with beta-thalassemia major has never before been reported in the literature.

  2. Evaluation of pulmonary function in beta-thalassemia major patients

    International Nuclear Information System (INIS)

    Objective: To describe and quantify the functional change of the lung in patients with beta-thalassemia major (TM) and determine the correlation between pulmonary function test (PFT) results with hemoglobin, ferritin and age changes. Methodology: Pulmonary function tests were performed on 60 transfusion-dependent patients with TM, ranging in age from 10 to 45 years. Percent-predicted values for forced expiratory volume in one second (FEV1), and forced expiratory flows (FEF) 25-75% were significantly reduced, whereas forced expiratory vital capacity (FVC) and FEV1/FVC were closed to normal limits, indicating a restrictive disease. All factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were negatively correlated with age and ferritin levels. In contrast, all factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were positively correlated with hemoglobin (Hb). We performed linear regression analysis to study the simultaneous influence of the presence of age, ferritin, and Hb on obstructive PFT indexes. Results: Pulmonary function test results were normal in only 32 (53.3%) of 60 patients and the rest 28 cases (46.7%) showed abnormal pulmonary function. FEV1 and FEF 25% - 75% have significant negative correlation with age (r = - 0.64 p(r) = 0.003 and r = - 0.58 p(r) = 0.02 respectively), also have significant positive correlation with Hb (r = 0.31 p(r) = 0.015 and r = 0.33 p(r) = 0.01 respectively), and only FEF 25% - 75% has significant negative correlation with ferritin (r -0.26 p(r) = 0.04). Conclusion: The present study has shown that restrictive disease and reduced lung diffusing capacity are the predominant abnormalities of pulmonary function patients with TM. The low hemoglobin concentration and a fall in the diffusing capacity of the alveola - capillary membrane, together with the dependence of the reduced pulmonary diffusing capacity on age and serum ferritin levels, as well as of the entity of restrictive disease on age, suggests that pulmonary

    This study concerns the effects of several pre-transplant features on outcome for patients with beta thalassemia major who underwent bone marrow transplantation (BMT). Seventy patients with beta thalassemia major underwent bone marrow transplantation during the period 1991-1997 in Shariati Hospital in Tehran, Iran. The survival and rejection curves levelled off at 8 and 18 months after transplantation at 82.6% and 11.4%, respectively. Pre-transplant clinical features (age, serum ferritin, portal fibrosis, hepatomegaly and quality of chelation therapy) were examined for their effects on survival and recurrence of thalassemia in this group of patients who were less than 16 years old. Increasing age, presence of portal fibrosis and increasing serum ferritin were significantly associated with reduced probability of survival (P = 0.0047, P = 0.016 and P = 0.024, respectively). Hepatomegaly and inadequate pre-transplant chelation therapy which were documented as poor prognostic factors in previous studies, were not evaluable in this study. We also showed the benefits of transplanting more than 5.5 x 10(8)/kg cells in this group of patients with no increase in complications.

    Background: Hypoparathyroidism is one of the most important endocrine complications of thalassemia major. This study was conducted to evaluate the prevalence of intracerebral calcifications in patients with thalassemia with and without hypoparathyroidism. Methods: 47 beta-thalassemia patients with hypoparathyroidism underwent a brain CT scan to investigate the presence and extent of intracerebral calcification. 30 age- and sex-matched beta-thalassemic patients with normal parathyroid function who had undergone brain CT for headache, or some other minor neurologic problems were also enrolled in the study serving as controls. The amount of intracerebral calcification, hematologic parameters, and some clinical findings were compared between both groups. Results: Intracerebral calcification was present in 54.2% of beta-thalassemia patients with hypoparathyroidism. The most frequent sites of calcification were basal ganglia, and frontoparietal areas of the brain. Thalami, internal capsule, cerebellum and posterior fossa were other less frequently calcified regions of the brain. In contrast, there was no evidence of intracerebral calcifications in the 30 thalassemic patients with normal parathyroid function. There was not a statistically significant difference between serum ferritin concentrations in thalassemia patient with hypoparathyroidism and those with normal parathyroid function (2781 vs. 2178, P > 0.05). Conclusion: Intracranial calcification is a common finding in thalassemia patients with hypoparathyroidism, it can be extensive and involves most regions of the brain.

    Full Text Available Background and purpose: Beta-thalassemia major (TM, a chronic, genetically determined hematological disorder, has received little investigation on the psychological aspects of the disease and the psychosocial adjustment of patients with this anemia. In the present study, the aim was to explore the nature of psychopathology according to age, sex, school performance, severity and complications of the disease in TM patients compared with demographically matched healthy persons.Materials and Methods: A controlled anterograde cohort study was conducted at the Thalassemia Unit of Boo-Ali Hospital from June 2003 to November 2005 in Sari, Iran. Psychological aspects were evaluated by the Persian version of symptoms checklist-90-revised questionnaire. Information on relevant demographic characteristics, school performance, severity and complications of the disease was collected by one of the investigators who had created the questionnaire.Results: 125 persons with TM completed the questionnaires and were compared with 125 controls and 250 totally. The mean age of the participants was 18.51± 2.0 years and with a range of 15-25 years. 132 (52.8% were female with equal family status, social and economic status. Patients group reported a significantly lower level of marital status (P<0.01, education level (P<0.0001, school performance (P<0.0001. TM patients were found to have significantly more psychiatric disorders than the control subjects with GSI: 1.16 ± 0.47 vs. 1.01 ± 0.6; (P<0.03, PSD: 54.99 ± 12.59 vs. 46.42 ± 18.76 (P<0.0001, and PSDI 2.02±1.02 vs 2.45 ± 2.22 (P<0.05.

    Full Text Available Objective:The thalassemias are among the most common genetic disorders worldwide, occurring more frequently in the Mediterranean region. The aim of this study was to determined frequency of sensory-neural hearing loss in major ß- thalassemias transfusion dependent patients in south of Iran. Methods:A cross sectional study on 308 cases of major beta-thalassemia patients referring to Thalassemia Center of Shiraz University of Medical Sciences between 2006-2007 years. The diagnosis of ß- thalassemia major was based on clinical history, complete blood count and hemoglobine electrophoresis. Clinical data such as serum ferritin level, deferoxamine (DFO dose, mean daily doses of DFO (mg/kg and audiometric variables was recorded. Findings:Out of 308 cases, 283 (96.5% had normal hearing and 10 (3.5% sensorineural hearing loss. There was no statically significant difference between two groups regarding mean age, weight, age at the first blood transfusion, age at the first DFO infusion. Conclusion:We found the lowest incidence of sensorineural hearing loss in a large population of patients suffered from major thalassemia who received DFO. We show that DFO is not ototoxic at a low dose. When considering all related literature, as a whole there has been much critical misrepresentation about DFO ototoxicity.

    Full Text Available Objective: Beta-thalassemia major (β-TM is a chronic, genetic and hematological disorder. Children and teenagers with chronic physical illnesses exemplified by thalassemia are vulnerable to emotional and behavioral problems. The aim of this study was to evaluate mental health and its related factors among young patients with beta-thalassemia major. Methods: In this cross-sectional observational descriptive-analytic study, we studied 164 patients suffering from Beta-thalassemia major with age range of 15-24 years who referred for treatment to Ali Ebn-e Abitaleb (AS University Hospital in Zahedan, a city in South East of Iran, during 2009- 2010. The demographic data and pattern of mental health were collected by standard general health questionnaire (GHQ-28.Data was analyzed using statistical software SPSS (version 17.0; Student t test and Chi-square (χ2 were used. Results: In this study, 96 (58.5% patients were male; the mean age of all patients was 18.78 ±2.28. Based on data analysis, 83 patients (50.8% suspected to have psychiatric disorders (58.8% of girls, 44.8% of boys. In addition, frequency of somatic symptoms, depression disorder, anxiety disorder and social dysfunction in all patients were 7.3%, 11.6%, 8.5% and 4.3% respectively. In illiterate patients, 70.4% suspected to have psychiatric disorder. Except for somatic disorder, other mental disorders were more frequent in girls. No significant association was found between mental state and gender, marital and literacy status and occupation. Conclusion : In this study, due to high prevalence of psychological disorders in young patients with Beta-thalassemia major, especially in girls, we suggest implementing further educational psychological programs to decrease the frequency of disorders. Moreover, conducting more quantitative and comprehensive researches is suggested to evaluate specific effective factors in psycho-social health.

    Full Text Available Beta-thalassemia major (TM remains to be one of the major health problems particularly in developing countries. Tunisia is a part of the Mediterranean countries mostly affected by this disease which is highly concentrated in small towns in families with low-income earners. The main objectives of this study are to provide a description of the demographic, clinical features and transfusion-related complications in patients with TM living in Tunisia. A standardized questionnaire was sent to clinicians throughout 33 different medical institutions caring for thalassemic patients. 391 transfusion dependant thalassemic patients with a median age of 10.7 years (range 3 months- 31 years were included in the study.The majority were originated from the north west of the country .A moderate overload between 1501 and 2500ng/ml was found in 61patients, while 81 patients (26.9% had ferritin level more than 2500 ng/ml and greater than 5000ng/ml in 21 patients (6.9%. 51 patients died from complications related to their disease. Heart failure was the main cause of death. The incidence of cardiac, endocrine, and infectious complications will be reviewed. Preventive measures such as health education, carrier screening and premarital screening remain the best ways for lowering the incidence of these diseases, which might be reflected in financial saving, social benefits and health benefits.

    Full Text Available Background and Objective: High prevalence of tha-lassemia in the North of Iran is a major challenge of medical practitioners in this area. To investigate the prevalence of abdominal ultrasound findings in these patients, the present study was conducted. Materials and Methods: Two hundred patients (92 girls and 108 boys, all suffering from Beta thalas-semia major with a mean age of 14.5 years (ranging from 5 to 34 years were included in the study. Ab-dominal ultrasound examination was performed by two radiologists between 2001 and 2005 to detect sonographic findings in these patients. Results: Hepatomegaly was presented in 75% of these patients and splenomegaly was detected in 46% of them while 45% of cases had undergone splenec-tomy. Total incidence of gall bladder stone formation was 14% (15.5% in females and 11.9% in males and it had a direct correlation with the patients’ age. Lymphadenopathy of portohepatic and celiac area was detected in 138 (68% patients. In 4 patients ul-trasound revealed portal vein thrombosis whereas in the other 4 cases, splenic extramedullary hematopoi-esis was detected. Conclusion: This study revealed that a remarkable portion of patients had developed these complica-tions. Authors suggest ultrasound to be a part of rou-tine examinations in beta thalassemia major patients who receive multiple transfusions.

    The study aims at describing the MR features of pancreas in beta-thalassemia major, investigating the relations between MR findings and glucose disturbances and between hepatic and pancreatic siderosis. Signal intensity ratios of the pancreas and liver to right paraspinous muscle (P/M, L/M) were retrospectively assessed on abdominal MR imaging studies of 31 transfusion-dependent patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 10 healthy controls, using T1- (120/4/90), intermediate in and out of phase - (120/2.7, 4/20), and T2*-(120/15/20) weighted GRE sequences. Using the signal drop of the liver and pancreas on opposed phase images, we recorded serum ferritin and results of oral glucose tolerance test (OGTT). Decreased L/M and P/M on at least the T2* sequence were noticed in 31/31 and 30/31 patients, respectively, but no correlation between P/M and L/M was found. Patients with pathologic OGTT displayed a higher degree of hepatic siderosis (p < 0.04) and signal drop of pancreas on opposed phase imaging (p < 0.025), implying fatty replacement of pancreas. P/M was neither correlated with glucose disturbances nor serum ferritin. Iron deposition in the pancreas cannot be predicted by the degree of hepatic siderosis in beta-thalassemia major. Fatty replacement of the pancreas is common and may be associated with glucose disturbances. (orig.)

    Currently, hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with beta-thalassemia major, but liver iron overload in these patients will not decrease and hepatic fibrosis may still progress despite successful HSCT. Liver biopsy samples were taken from 14 patients (Out of 25 patients) who underwent HSCT. All patients met three criteria: negative HCV antibody, liver fibrosis in samples before HSCT and lack of regular treatment for iron overload after HSCT (Because patients did not consent to phlebotomy or they had not regular follow-up). We evaluated liver fibrosis and liver iron overload by a semi quantitative method, Perls' Prussian blue staining, before and after HSCT. HSCT was successful in all the patients. Liver iron overload did not change after transplant (P=0.61), but hepatic fibrosis progressed after transplant (P=0.01). In patients with beta thalassemia major who previously had some degree of liver fibrosis, HSCT alone cannot reduce liver iron overload and liver fibrosis will increase. We recommend that regardless of the amount of iron overload in patients with beta thalassemia major that have shown some degree of fibrosis in their liver biopsy before transplantation, appropriate steps should be taken to reduce iron overload as soon as possible after successful transplantation.

    Full Text Available Thalassemia is a common hereditary hemoglobinopathy disorder that affects many organs in the body. Estimation of kidney function is important, as it is the vital organ that plays the major role in the elimination of accumulated iron as well as the chelating drugs that have to be used as therapy. Sixty- three patients aged 1-29 years, with a mean ± SD of 14 ± 6.7 years, affected with beta- thalassemia major in Tabriz Children′s Hospital were evaluated for their renal function on the basis of their age, serum iron, serum ferritin and serum creatinine levels along with two methods of estimating glomerular filtration rate (GFR; by Schwartz method for those under 18 years old and using Modification of Diet in Renal Disease (MDRD formula for those who were 18 years and above. Elevation of serum creatinine denoting renal dysfunction was not seen in our patients, but hyperfiltration was a common finding. An increasing GFR was observed, which corresponded to age, but no relationships were seen between serum iron, serum ferritin, regular blood transfusion, chelating therapy to GFR.

    Occult hepatitis C virus infection (OCI) is a new pathological form of chronic hepatitis virus (HCV) infection characterized by the presence of HCV RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) specimens and the absence of HCV RNA and anti-HCV antibodies (Abs) in plasma samples. β-thalassemia major is a hereditary recessive blood disease with deficiency in the hemoglobin beta chain. Thalassemic patients need blood transfusion therapy; repeated blood transfusion increases the risk of viral blood-borne infection. The aim of this study was to determine the prevalence of OCI in Iranian patients with β-thalassemia major. From February 2015 to November 2015, a total of 147 Iranian patients with β-thalassemia major were enrolled in this cross-sectional study. After extraction of viral RNA from the plasma and PBMC samples, HCV genomic RNA in the specimens was amplified by RT-nested PCR using primers from the 5'-UTR. The HCV genotypes of the positive specimens were tested using the RFLP assay. To confirm the HCV genotypes, the 5'-UTR fragment was amplified and cloned into the pJET1.2/blunt cloning vector and then sequenced. Out of 147 patients, 106 (72.1 %) were negative for anti-HCV Abs and HCV RNA. HCV RNA was found in PBMC specimens of six (5.7 %) patients, from a total of 106 patients with undetectable plasma HCV RNA and anti-HCV Abs. Therefore, six out of 106 patients had OCI. HCV genotyping revealed that three patients were infected with HCV subtype 1b, two patients were infected with HCV subtype 3a, and one patient was infected with HCV subtype 1a. These results revealed that Iranian patients with beta-thalassemia major might have OCI. Therefore, it seems that the design of a study to identify this infection in patients with β-thalassemia major would provide valuable information. PMID:27132015

    Full Text Available Objectives: Chelating agents remain the mainstay in reducing the iron burden and extending patient survival in homozygous beta-thalassemia but adverse and toxic effects may increase with the institution and long term use of this essential therapy. This study aimed to estimate the incidence of deferasirox (DFX side effects in patients with thalassemia major or intermedia.Methods: A retrospective study of 72 patients (mean age: 20.3±0.9 yrs; 36 male, 36 female with thalassemia major or intermedia treated at Sultan Qaboos University Hospital, Oman, was performed to assess the incidence of side effects related to deferasirox over a mean of 16.7 month follow-up period.Results: Six patients experienced rashes and 6 had gastro-intestinal upset. DFX was discontinued in 18 patients for the following reasons: persistent progressive rise(s in serum creatinine (7 patients; 40% mean serum creatinine rise from baseline, feeling unwell (2, severe diarrhea (1, pregnancy (1, death unrelated to chelator (2 and rise in serum transaminases (2. Three patients were reverted to desferoxamine and deferiprone combination therapy as DFX was no longer biochemically effective after 18 months of therapy. There was no correlation between baseline serum ferritin and serum creatinine or a rise in serum creatinine. Cardiac MRI T2* did not change with DFX therapy. However, there was an improvement in liver MRI T2* (p=0.013.Conclusion: Renal side effects related to deferasirox appear to be higher than those reported in published clinical trials. Further larger studies are required to confirm these findings.

    Full Text Available Major beta thalassemia (MBT is a hereditary disease which synthesies defects in beta chains of haemoglobin, it is causes red blood cell destruction and the symptoms of anemia. Red blood cell destruction, frequent blood transfusion and low adherence to routine use of iron chelator lead to iron accumulation in the heart, liver and endocrine organs. Accumulation of iron in the myocard can lead acute myocardial infarction. One of cardiac markers that had been used for the diagnosis of myocardial infarction was cardiac troponin I (cTnI. The aim of this research is find the correlation between serum ferritin levels and cTnI in MBT children. A descriptive analytic research was conducted using a cross sectional design. The subjects were divided into 2 groups, the MBT group and the control group. In both groups, the serum ferritin and cTnI levels ere evaluated. Data were analyzed using t-test and Pearson correlation test. Eleven children in the MBT group and 11 children in the control group were involved in this study. In the MBT group, the mean of serum ferritin and cTnI levels were 4292.5 µg/L and 0.20 ng/mL respectively. The mean of serum ferritin levels in the MBT group were higher than in the control and statistically significant (p= 0.0004. The mean of serum ferritin levels in the MBT group were higher than in the control and statistically significant (p= 0.0004. The mean of serum cTnI in the MBT group were higher than in the control, but statistically not significant (p= 0.82. In the MBT group, there was a weak corellation between serum ferritin and cTnI levels (r= 0.34.

    Osteoporosis affects approximately 40-50% of adult patients with beta-Thalassemia Major (beta TM). Recent data have implicated an altered modulation of the osteoprotegerin (OPG)/receptor activator of NFkB ligand (RANKL) system in the pathogenesis of beta TM-osteoporosis. OPG/RANKL system acts downstream from IL-1 alpha, IL-6 and TNF-alpha and it may be the final actor mediating the effects of these cytokines on the regulation of both postmenopausal and metabolic bone resorption. However, to date, there are no data on circulating levels of these pro-resorptive cytokines in beta TM patients. We investigated the potential relationships among these cytokines, several markers of bone turnover and bone mineral density (BMD) in beta TM patients. IL-1 alpha, IL-6 and TNF-alpha, OPG and RANKL serum levels, hemato-urinary bone remodeling markers and bone mineral density (BMD) at L2L4 and femoral neck as well as erythropoietin (EPO), 17beta-estradiol, and free-testosterone levels were measured in 30 well treated beta TM patients and in 20 healthy subjects, matched for age, sex and BMI with the patients. beta TM patients showed an altered bone turnover, with increased deoxypyridinoline (D-PYR) levels (P<0.0001), decreased osteocalcin (BGP) concentrations (<0.0001) and significantly lower lumbar (P=0.001) and femoral (P<0.05) BMD values as compared to controls. Circulating levels of IL-1 alpha (P<0.0001), TNF-alpha (P<0.0001) and IL-6 (P<0.05) were all increased in beta TM patients as compared with controls. In beta TM patients, IL-1 alpha was significantly related with D-PYR (r=0.5; P<0.05), RANKL (r=0.7; P=0.03) and IL-6 (r=0.3; P=0.006); IL-6 was also significantly correlated with D-PYR (r=0.5; P<0.05) and EPO levels (r=0.3; P=0.03); TNF-alpha showed a negative correlation with L2L4 BMD (r=-0.4; P<0.05). Our data demonstrate, for the first time, an association between increased circulating levels of pro-resorptive cytokines and an altered bone turnover in beta TM

    beta-Thalassemias are a group of heterogenous recessive disorders common in many parts of the world. Despite the great advances in the treatment of thalassemia, there is so far no cure, but perhaps bone marrow transplantation (BMT) is a possibility. Prevention, using prenatal diagnosis and selective abortion in the cases where the fetus is found to be affected, should be considered as a sensible alternative. During the past 5 years, 112 couples have been referred to our Center for detection of their beta-thalassemia (beta-thal) carrier status. In this group, common and rare mutations were detected. Of these, 106 couples (94.6%) came for counseling during pregnancy and six (5.4%) came before becoming pregnant. Prenatal diagnosis was performed for the 106 couples at risk. Fetal DNA was obtained from both chorionic villus sampling (CVS) (99) and amniotic fluid (7). Using reverse hybridization, 64 (60.4%) were found to be heterozygous for a beta-thal mutation and 24 (22.6%) were normal. Eighteen (17.0%) were found to carry an affected fetus and these pregnancies were terminated. PMID:19065331

    Full Text Available Objective: Cardiac failure due to iron overload remains the most common cause of death in patients with beta-thalassemia major. This study aimed to evaluate myocardial function in children with beta-thalassemia major using standard echocardiography technique and strain rate imaging. Materials and Methods: Conventional echocardiographic analysis, tissue velocity imaging, and strain/strain rate imaging of the left ventricle were evaluated in 48 children with beta thalassemia major (19 girls, 29 boys; 8.39±4.05 years and 22 healthy children (11 girls, 11 boys; 8±3.72 years. Results: Conventional echocardiographic examinations revealed that beta-thalassemia patients had larger left ventricular end-systolic diameter, end-diastolic and end-systolic volume, left ventricular mass index, and mitral early/late diastolic flow velocity ratio (p<0.05. Strain and strain rate imaging study of the basal lateral wall of the left ventricle was higher in patients than in controls, at p=0.035 and p=0.008, respectively. Conclusion: We found that superior systolic strain and strain rate imaging of the left ventricle indicated the presence of regional systolic function in the left ventricular wall. We suggest that left ventricle volume and mass index parameters might be more sensitive than the other conventional and strain/strain rate imaging parameters during childhood. However, the adulthood strain and strain rate imaging values may be lower than controls, exceeding the critical level of iron overload.

    Full Text Available Background: Thalassemia is a chronic disease that it leads to psychological and social problems for parents. Mothers are at markedly increased risk of suffering from psychological distress and depression because they usually take on a considerable part of extra care that their children need.This study was designed to determine prevalence and intensity of depression in mothers with a thalassemic child. Material and Methods: In this cross – sectional study, 65 mothers of children with thalassemia major (case group and 65 mothers of children without thalassemia major (control group were assessed using the Beck Depression Inventory (BDI. Data were analyzed by using SPSS (v 16.0 for windows. Results: Prevalence of depression was significantly higher in case group than that in control group (84.6%vs. 56.9%, p <0.05. Moderate depression had a highest prevalence in the both groups (33.4% in case group and 30.8% in control group. Prevalence of severe depression in case group was markedly higher than that in control group (29.2% vs. 3.1% p<0.05. There was a significant difference between intensity of depression in mothers of case group that had another child with beta-thalassemia major (p<0.05. Conclusion: Mothers of children with thalassemia major are vulnerable to depression. They need psychosocial support to promote their health.

    Beta-thalassemias are a group of hereditary blood disorders characterized by anomalies in the synthesis of the beta chains of hemoglobin resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic individuals. The total annual incidence of symptomatic individuals is estimated at 1 in 100,000 throughout the world and 1 in 10,000 people in the European Union. Three main forms have been described: thalassemia major, thalassemia intermedia and thalassemia minor. Individuals with thalassemia major usually present within the first two years of life with severe anemia, requiring regular red blood cell (RBC) transfusions. Findings in untreated or poorly transfused individuals with thalassemia major, as seen in some developing countries, are growth retardation, pallor, jaundice, poor musculature, hepatosplenomegaly, leg ulcers, development of masses from extramedullary hematopoiesis, and skeletal changes that result from expansion of the bone marrow. Regular transfusion therapy leads to iron overload-related complications including endocrine complication (growth retardation, failure of sexual maturation, diabetes mellitus, and insufficiency of the parathyroid, thyroid, pituitary, and less commonly, adrenal glands), dilated myocardiopathy, liver fibrosis and cirrhosis). Patients with thalassemia intermedia present later in life with moderate anemia and do not require regular transfusions. Main clinical features in these patients are hypertrophy of erythroid marrow with medullary and extramedullary hematopoiesis and its complications (osteoporosis, masses of erythropoietic tissue that primarily affect the spleen, liver, lymph nodes, chest and spine, and bone deformities and typical facial changes), gallstones, painful leg ulcers and increased predisposition to thrombosis. Thalassemia minor is clinically asymptomatic but some subjects may have moderate anemia. Beta-thalassemias are caused by point mutations or, more rarely, deletions in the beta

    This study aimed at describing the magnetic resonance (MR) imaging features of the adrenal glands in beta-thalassemic patients and at investigating the relation between adrenal and hepatic siderosis. Adrenal signal intensity (SI) was retrospectively assessed on abdominal MR studies of 35 patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 12 healthy controls, using T1- (120/4/90), intermediate - (120/4/20), and T2*- (120/15/20) weighted GRE sequences. Adrenal SI was graded as grade 0 (normal SI on all sequences), grade 1 (hypointensity on T2* alone), or grade 2 (hypointensity on at least T2*). Adrenal size was measured in the thalassemic patients and compared with normative data. Liver-to-muscle (L/M) SI ratios, expressing hepatic siderosis, were estimated on each sequence. Serum ferritin levels were recorded. Adrenal hypointensity (grades 1 and 2) was noted in 24/35 (68.6%) patients. L/M ratios correlated significantly with adrenal SI in all sequences. Patients with grade 1 and grade 2 adrenal SI had significantly decreased L/M ratios compared with grade 0. Serum ferritin correlated significantly with L/M values but not with adrenal SI. Adrenal size was within normal limits. Diffuse hypointensity in normal-sized adrenals is a common MR finding in beta-thalassemic patients and correlates with the degree of hepatic siderosis. (orig.)

    International Nuclear Information System (INIS)

    The purpose of this study is to describe the MR imaging features of bone marrow in beta-thalassemia major and investigate their relation to ferritin, liver and spleen siderosis. Spinal bone marrow was prospectively assessed on abdominal MR studies of 40 transfused beta-thalassemic patients and 15 controls using T1-w, Pd, T2*-w Gradient Echo (GRE) and T1-w turbo Spin Echo (TSE) sequences. Signal intensity (SI) ratios of liver, spleen and bone marrow to paraspinous muscles (L/M, S/M, B/M respectively) and the respective T2 relaxation rates (1/T2) were calculated. Serum ferritin levels were recorded. Bone marrow hypointensity in at least T2*-w GRE sequence was noted in 29/40 (72.5%) patients. Eleven/40 patients exhibited normal B/M on all MR sequences. Five/40 patients had normal B/M and low L/M. B/M correlated with L/M in T1-w TSE sequence only (r = 0.471, p = 0.05). B/M correlated with S/M and mean ferritin values in all sequences (r > 0.489, p - 0.496, p < 0.03 respectively). Marrow 1/T2 did not correlate with ferritin values or liver and spleen 1/T2. B/M in transfused beta-thalassemic patients is related to splenic siderosis and ferritin levels. Although marrow is usually hypointense, it may occasionally display normal SI coexisting with liver hypointensity, a pattern typical of primary hemochromatosis. (orig.)

    2009-01-01

    Full Text Available We describe a 16 year-old male with ß thalassemia major and gait disturbances that had not been given blood transfusions due to a severe childhood transfusion reaction. Thoracic spine MRI demonstrated hematopoietic marrow throughout the spine and epidural masses causing cord compression consistent with extramedullary hematopoiesis (EMH. After treatment with steroids, radiotherapy and monitored blood transfusions, the patient demonstrated significant improvement of his paraspinal lesions and near complete resolution of his neurological symptoms. While EMH causing cord compression in adolescents is rare in the current era of bone marrow transplantation or chronic transfusions, it should be considered when thalassemia major patients present with neurological deficits. The well defined imaging features of EMH can play a central role in its diagnosis and management, especially because surgical and / or radiotherapeutic intervention are often considered in cases of failed medical treatment.

    Full Text Available To evaluate the prevalence of renal tubular dysfunction in children with β-thalassemia (β-T major, we studied the glomerular and tubular function in 140 children with β-T major and compared them to a healthy control group at our center from May 2007 to April 2008. Fresh first morning samples were collected from each patient and analyzed for sodium, potassium, calcium (Ca, protein, uric acid (UA, creatinine (Cr, urine osmolality and urinary N-acetyl-β-D-glucosaminidase (UNAG activity. Blood samples were also collected for complete blood count, blood urea nitrogen (BUN, fasting blood sugar, serum creatinine (SCr, electrolytes, and ferritin before transfusion. Among the study patients, 72 were males, and the mean age was 11.5 (ranging 7-16 years. SCr levels were all within normal limits and all of them had normal glomerular filtration rate (GFR. The mean UNAG was 17.8 IU/L in the study patients (normal 0.15-11.5 IU/L and 3.2 IU/L in the control group (P 0.21 (P = 0.006. Nine (6.4% thalassemic patients with a mean age of 12 years had proteinuria (Upr/UCr > 0.2. Sixty-nine (49.3% out of the 140 patients and 45 (65.2% of the patients having UNAG had uricosuria also (UUA/UCr > 0.26. Ten (7% patients had microscopic hematuria and 10 (7% patients with a mean age of 13.5 years had glucosuria or diabetes mellitus. We conclude that tubular dysfunction is a relative common complication of the β-T major; UNAG and its index are the best to detect renal tubular dysfunction in these patients. Currently, periodic measurement of UCa/UCr and UUA/UCr ratios as well as urinalysis are recommended.

    2013-06-01

    Full Text Available Background: Thalassemia is a hereditary hemoglobinopathy whose most common complication is cardiac involvement which ends up in these patients’ death. Since troponin is a sensitive and specific marker for the detection of microinfarct, we studied the relationship between troponin and ferritin serum levels for early diagnosis of cardiac involvement in these patients. Materials and Methods: This case-control study was performed on 80 patients, including 40 patients with major thalassemia and normal echocardiography and 40 healthy volunteers ranging from 6 months to 16 years old. All the children were examined and the eligible children who were not infected with known heart disease, iron deficiency anemia, kidney disease, diabetes, fever, and systemic diseases were enrolled into the study after obtaining written informed consents from their parents. At 8:00 A.M. before breakfast, 5cc blood was drawn from these children. After collecting the samples, ferritin and troponin serum levels were evaluated using ELISA and electro- kymonolonsense methods, respectively. The gathered data were analyzed through the SPSS statistical software (v. 20 and T-test. Besides, P value<0.05 was considered as statistically significant. Results: The study results revealed a significant difference between the two groups regarding the mean of the serum levels of troponin (P=0.045 and ferritin (P=0.001. In this study, no significant correlation was observed between serum troponin and ferritin levels and age and BMI in the two groups. Also, no significant relationship was found between serum troponin level and sex (P=0.264. Conclusions: In microinfarct, troponin increases independent of ferritin; therefore, it can be used for early detection of cardiac involvement in thalassemia patients to determine the sub-clinical effects.

    Full Text Available Objective: Dilated cardiomyopathy is the end result of chronic iron overload in patients with beta thalassemia major. The objective of the present study was to evaluate the safety and efficacy of Carvedilol in patients with beta thalassemia major and dilated cardiomyopathy.Methods: During a six-month period, fourteen patients with beta-thalassemia major and heart failure without diabetes mellitus referred to pediatric cardiology clinic enrolled in this double blind, randomly assigned study. All patients were on anti failure therapy with Digoxin, Captopril and Furosemide. Carvedilol was started at a dosage of 3.12 mg bid and for patients who had a systolic blood pressure >100 mmHg, heart rate >60/min and no signs of low cardiac output the dosage was increased every two weeks to a maximum of 25 mg bid. Clinical signs and symptoms, systolic and diastolic echocardiographic indexes and Tissue Doppler Imaging (TDI data were collected from each patient.Findings: Eight patients received Carvedilol (Group 1 and six received placebo (Group 2. The mean age of patients in Group1 and 2 were 16±0.7 years and 17±3 years respectively. Only one patent in Group 1 tolerated increasing Carvedilol dosage to more than 6.25 mg bid. Changes in New York Heart Association (NYHA classification, Ejection fraction, End diastolic dimension changes, TDI systolic(S, early (Ea and late (Aa diastolic waves were not statistically significant in these two Groups (P>0.05. Pulse Doppler E/A wave ratio of mitral valve in Group1 and Group 2 changed from 1.1±0.37 m/s to 1.8±0.40 m/s and from 1.34±0.30 m/s to 2.6±0.23m/s respectively (P=0.04.Conclusion: Patients with thalassemia and dilated cardiomyopathy have poor tolerance to increasing Carvedilol dosage and develop decreased systolic blood pressure during advancement of the drug dosage. Carvedilol can be effective in prevention of progression of diastolic dysfunction in these patients.

    Beta-thalassemia major patients have chronic anemia and are dependent on blood transfusions to sustain life. Molecular characterization and prenatal diagnosis of beta3-thalassemia is essential in Malaysia because about 4.5% of the population are heterozygous carriers for beta-thalassemia. The high percentage of compound heterozygosity (47.62%) found in beta-thalassemia major patients in the Thalassaemia Registry, University of Malaya Medical Centre (UMMC), Malaysia, also supports a need for rapid, economical, and sensitive protocols for the detection of beta-thalassemia mutations. Molecular characterization of beta-thalassemia mutations in Malaysia is currently carried out using ARMS, which detects a single beta-thalassemia mutation per PCR reaction. We developed and evaluated Combine amplification refractory mutation system (C-ARMS) techniques for efficient molecular detection of two to three beta-thalassemia mutations in a single PCR reaction. Three C-ARMS protocols were evaluated and established for molecular characterization of common beta-thalassemia mutations in the Malay and Chinese ethnic groups in Malaysia. Two C-ARMS protocols (cd 41-42/IVSII #654 and -29/cd 71-72) detected the beta-thalassemia mutations in 74.98% of the Chinese patients studied. The CARMS for cd 41-42/IVSII #654 detected beta-thalassemia mutations in 72% of the Chinese families. C-ARMS for cd 41-42/IVSI #5/cd 17 allowed detection of beta-thalassemia mutations in 36.53% of beta-thalassemia in the Malay patients. C-ARMS for cd 41-42/IVSI #5/cd 17 detected beta-thalassemia in 45.54% of the Chinese patients. We conclude that C-ARMS with the ability to detect two to three mutations in a single reaction provides more rapid and cost-effective protocols for beta-thalassemia prenatal diagnosis and molecular analysis programs in Malaysia.

    Full Text Available Introduction : Patients with major thalassemia need recurrent transfusions and if not treated are at risk of heart dysfunction. Heart tissue could be abnormal in patients who use desferral continously due to iron deposits , fibrosis , hypertrophy and side effects of chronic anemia. Cardiac involvement is the main cause of morbidity and mortality in major thalassemics, so we decided to improve early diagnosis of cardiac involvement by measuring myocardial performance index( MPI . Method & Materials : This case-control study was performed from April 2003 to December 2003 at the Ali-Asghar pediatrics hospital, Zahedan, Iran. MPI of both ventricles was measured by Doppler echocardiography in 48 patients with major thalassemia aged between 10-18 years and compared with 48 age , sex-matched controls. Patients had no abnormality in physical examination , chest x-ray and ECG and echocardiography did not show heart failure. Hemoglobin and serum ferritin levels was measured in all patients before echocardiography. Results: Mean age of patients was 12.3±2.4 years and that in the control group was 12.7±2years . Right ventricle isovolumetric relaxation time (RVIRT (107 ± 14 vs 94 ±14 , p0.05 and LVICT (31 ± 13 vs 21 ± 15 , p0.05 in the two groups. Finally, RVMPI (0.59 ± 0.12 Vs 0.46 ± 0.12 , p<0.001 was increased in 87% of patients and LVMPI (0.49 ± 0.12 Vs 0.41± 0.09 , p0.05. Conclusion: This study showed that RVMPI and LVMPI increase in major thalassemia patients that indicates systolic and diastolic dysfunction and RVMPI increases more than LVMPI. On the other hand, MPI has a direct correlation with serum ferritin . On the basis of this study ,we suggest MPI measurement in serial echocardiography in asymptomatic major thalassemia patients.

    Full Text Available Iron Overload Cardiomyopathy (IOC is still the main cause of death in thalassemia major (TM patients. Unfortunately, Conventional Echocardiography fails to predict early cardiac dysfunction. As Tissue Doppler Imaging (TDI may demonstrate regional myocardial dysfunction, we wondered if exercise may reveal abnormalities at TDI which are not evident at rest. To try to evaluate left and right myocardial performances at rest and after maximal exercise by both conventional and TDI parameters, 46 beta-TM adult patients and 39 control subjects were enrolled. All patients had a liver iron quantification by Superconducting Quantum Interference Device (SQUID and also a cardiac iron assessment by MRI (T2*: 38 TM patients had no evidence of cardiac iron overload. Whereas TM patients did not shown diastolic dysfunction and all of them presented a good global response to exercise, TDI detected a reduced increase of the S’ waves of left ventricle basal segment during exercise. This finding seems to have some weak but interesting relations with iron overload markers. In conclusion, in our study, exercise stress TDI-echocardiography was able to demonstrate subtle systolic abnormalities that were missed by Conventional Echocardiography. Further studies are required to determine the meaning and the clinical impact of these results.

    Introduction: Thalassemia is the most common hereditary blood disorder in the world. Iran is located on the thalassemic belt and there is a high prevalence of the hepatosplenomegaly in beta thalassemia minor patients which is reported to be very variable. The goal of this research was to study the frequency of these signs in the cases with beta thalassemia minor patients in Iran. Materials and methods: Two hundred and fifty-nine cases that referred to center for pre-marriage tests were divided into two groups according to their MCV, MCH, and HbA2 (beta thalassemia minor cases and control groups). Liver and spleen sizes were determined by ultrasonographic method and the two groups were compared with each other. Results: Average spleen volumes in case and control groups were 163.48 {+-} 133.97 and 126.29 {+-} 53.98 mm{sup 3}, respectively. Average spleen lengths in case and control groups were 10.71 {+-} 1.52 and 10.60 {+-} 5.4 cm, respectively. Conclusion: In the regions with high frequency of beta thalassemia, in case of finding large spleen size in the ultrasonography, a probable harmless differential diagnosis will be beta thalassemia minor that is not indicative of any serious disease. Volumetric measurement of spleen is more reliable for detection of splenomegaly in these patients.

    Full Text Available BACKGROUND: Thalassemia is the most common hereditary disease in the world. Thalassemic erythrocytes are exposed to higher oxidative stress and lipid peroxidation. The aim of this study was to investigate the effects of beta-carotene and vitamin E on erythrocytes lipid peroxidation in beta-thalassemia patients.
    METHODS: A prospective double-blind, placebo-controlled study of the effect of beta-carotene and vitamin E on lipid peroxidation in erythrocytes membranes was performed on 120 beta-thalassemia major patients in four groups. The patients were supplemented for 4 weeks as follows: group 1 with beta-carotene (13 mg/day, group 2 with vitamin E (550 mg/day, group 3 with beta-carotene plus vitamin E and group 4 with placebo. We prepared all capsules for 4 roups in the same shape and color. Measurements of serum beta-carotene and vitamin E were performed by high performance
    liquid chromatography. After preparation of ghost cells from blood specimens, malondialdehyde (MDA was determined as index of lipid peroxidation in erythrocytes membranes before and after treatment. RESULTS: The levels of serum beta-carotene and vitamin E were significantly lower and MDA concentrations in erythrocytes membranes were significantly higher in beta-thalassemia patients compared to controls (P<0.001. In groups that treated with vitamin supplements for 4-weeks, lipid peroxidation rates were significantly reduced after treatment (P<0.001, but in placebo group there was not significant difference (P>0.05.
    CONCLUSIONS: Our findings provide evidence that an oral treatment with beta-carotene and vitamin E can significantly reduce lipid peroxidation of erythrocytes membranes and could be useful in management of beta-thalassemia major patients. KEYWORDS: Beta-thalassemia major, beta-carotene, vitamin E, malondialdehyde, lipid peroxidation.

    The study of a Malian family has allowed to prove existence of two types of beta-thalassemia genes: the beta0 gene which suppresses the synthesis of the beta chain into cis position and the beta+ gene which slows down only partially this synthesis. The difference between this two genes has been possible owing to the hemoglobin C found in this family and induced by the betaC mutated gene. The segregation of the four genes betaA, betaC, beta0 thal, and beta+ thal. has allowed to compare all the possible phenotypes deriving from the combinations by two of these allelic genes.

    Full Text Available Background: HbA2 plays a key role in screening programs for beta thalassemia because a small increase in this fraction is the most important marker of beta thalassemia heterozygous carriers. The potential impact of coincident iron deficiency on HbA2 based identification of beta thalassemia minor is worrisome issue for screening laboratories, this is especially true for resource-constrained settings where iron deficiency is wide spread and molecular confirmatory tests for borderline HbA2 values may be unavailable. Objective: the aim of this study is to evaluate the effect of iron deficiency on HbA2 level in order to improve the detection of beta thalassemia trait with or without iron deficiency in our population. Materials and Method: In this study 145 individuals were enrolled including normal controls (50, beta thalassemia minor (50 and coincident beta thalassemia with iron deficiency cases (45. Complete blood count, serum iron, total iron binding capacity and HbA2 with HbF estimation were done for every individual. Result: The mean HbA2 level was (2.4± 0.4 in control, (5.2 ± 0.9 in beta thalassemia minor and 5.1± 0.9 in coincident iron deficiency with beta thalassemia minors. All hematological parameters were significantly lower in beta thalassemia minor and coincident iron deficiency with beta thalassemia minor in comparison to the control group .Mean HbA2 level did not show a significant difference in thalassemia minor (5.2±0.9 when compared with the mean HbA2 levels in coincidentiron deficiency with beta thalassemia minor. Conclusion: The presence of iron deficiency did not preclude the detection of beta thalassemia minor in our population

    Spinal cord compression due to extramedullary hematopoiesis is a well-described bu rare syndrome encountered in several hematologic disorders, including {beta}-thalassemia. We report a case of a patient with intermediate {beta}-thalassemia and crural paraparesis due to spinal cord compression by a paravertebral extramedullary mass. She was successfully treated with low-dose radiotherapy and transfusions. After splenectomy, she was regularly followed up for over four years without transfusion or recurrence of spinal cord compression. Extramedullary hematopoiesis should be investigated in patients with hematologic disorders and spinal cord symptoms. The rapid recognition and treatment with radiotherapy can dramatically alleviate symptoms. (author)

    This study was planned to explore the self-concept, behavioral, and parental attitudes of the children with beta-thalassemia major, and the factors that affect them. The study was undertaken between January and June 2004 at the Hacettepe University Ihsan Doğramaci Children's Hospital, Pediatric Hematology Unit, Ankara and 43 voluntary children with beta-thalassemia major on regular blood transfusion and iron chelation treatment between the ages of 5.0 and 18.0 years were included into the study. Age, sex, birth order, school performance, hemoglobin value, serum ferritin levels, associated illness, splenectomy status, presence of thalassemic sibling or relatives, death of thalassemic relatives, place of residence, maternal and paternal education were recorded. Parental Attitude Research Instrument, Piers-Harris Self-Concept Scale, and Child Behavior Checklist were applied. Higher educated mothers have lower overprotection (P=0.009), parental discordance (P=0.044), and discipline scores (P=0.002) than lower educated mothers. In cases with death of thalassemic relatives, democratic/equality attitude scores were decreased (P=0.034). With stepwise multiple linear regression analysis, splenectomy, good school achievement, absence of death of thalassemic relatives, and serum ferritin levels were found to increase Piers-Harris Self-Concept Scale; however, total behavior problem score was found to decrease with increasing age, splenectomy and decreasing overprotection subscale of Parental Attitude Research Instrument scores. The self-esteem and behavior problems of children with thalassemia depended not only on the variables related exclusively to the child (age, school achievement) and the illness-associated conditions (splenectomy, serum ferritin levels) but also on the parental attitude (overprotection).

  9. Prevalence of Beta-Thalassemia in premarital screening in Al-Hassa, Saudi Arabia

    International Nuclear Information System (INIS)

    The Al-Hassa area is one of the regions in Saudi Arabia where hemoglobinopathies are prevalent. The Saudi Ministry of Health designed a protocol for premarital testing after the royal decree in December 2003. The protocol was implemented in a February 2004 order. The aim of this study was to determine the prevalence of beta-thalassemia trait among subjects coming for premarital screening in the Al-Hassa area. From February 2004 to November 2004, healthy subjects coming to six marriages consultation centers in the Al-Hassa area underwent routine mandatory tests. Subjects were considered to have beta-thalassemia trait if they had a mean corpuscular volume (MCV), 80 fL and/or a mean corpuscular hemoglobin (MCH) 3.2%. Venous blood was taken into ETDA tube and the complete blood count and red blood cell indices were measured by a Coulter automated cell counter on the same day of hemoglobin collection. Electrophoresis was done on cellulose acetate. All Saudi participants (n=8918), including 4218 (47.3%) males and 4700 (52.7%) females were screened. The prevalence of beta-thalassemia trait with high hemoglobin A2 and microcytic hypochromic anemia was 3.4% (307/8918). In countries with a high prelevance of hemoglobinopathies, a premarital screening program is helpful for identification and prevention of high-risk marriages. With a 3.4% prevalence of beta-thalassemia trait in premarital couples, future comprehensive programs are needed to know the actual prevalence of beta-thalassemia in Al-Hassa. (author)

    Beta-thalassemia is a genetic disorder with mutations in the β-globin gene that reduce or abolish β-globin protein production. Patients with β-thalassemia major (Cooley's anemia) become severely anemic by 6 to 18 months of age, and are transfusion dependent for life, while those with thalassemia intermedia, a less-severe form of thalassemia, are intermittently or rarely transfused. An allogeneically matched bone marrow transplant is curative, although it is restricted to those with matched donors. Gene therapy holds the promise of "fixing" one's own bone marrow cells by transferring the normal β-globin or γ-globin gene into hematopoietic stem cells (HSCs) to permanently produce normal red blood cells. Requirements for effective gene transfer for the treatment of β-thalassemia are regulated, erythroid-specific, consistent, and high-level β-globin or γ-globin expression. Gamma retroviral vectors have had great success with immune-deficiency disorders, but due to vector-associated limitations, they have limited utility in hemoglobinopathies. Lentivirus vectors, on the other hand, have now been shown in several studies to correct mouse and animal models of thalassemia. The immediate challenges of the field as it moves toward clinical trials are to optimize gene transfer and engraftment of a high proportion of genetically modified HSCs and to minimize the adverse consequences that can result from random integration of vectors into the genome by improving current vector design or developing novel vectors. This article discusses the current state of the art in gene therapy for β-thalassemia and some of the challenges it faces in human trials.

    {beta}-Thalassemia is a hereditary disease caused by any of 90 different point mutations in the {beta}-globin gene. Specific populations generally carry a small number of mutations, the most common of which are those that are widely distributed regionally. The present study constitutes an extensive molecular characterization of this disease in a small, highly inbred ethnic group with a high incidence of {beta}-thalassemia-the Jews of Kurdistan. An unusual mutational diversity was observed. In 42 sibships 13 different mutations were identified, of which 3 are newly discovered. Four of the mutations are unique to Kurdish Jews and have not been discovered in any other population. A fifth was found outside Kurdish Jews only in an Iranian from Khuzistan, a region bordering Kurdistan. Two-thirds of the mutant chromosomes carry the mutations unique to Kurdish Jews. The authors traced the origin of the mutations to specific geographic regions within Kurdistan. This information, supported by haplotype analysis, suggests that thalassemia in central Kurdistan (northern Iraq) has evolved primarily from multiple mutational events. They conclude that several evolutionary mechanisms contributed to the evolution of {beta}-thalassemia in this small ethnic isolate.

    Full Text Available Rare disorders are defined as diseases, including those of genetic origin, which are life-threatening or chronically debilitating, which are of such low prevalence that special combined efforts are needed to address them. We present a case with a rare association between two genetic conditions: Turner phenotype and beta thalassemia minor. Turner syndrome is a chromosomal disorder that is characterized by the absence of all or part of a second sex chromosome in some or all cells. This condition occurs in 1 in 2,500 to 3,000 girls. The physical features include webbing of the neck, short stature, delayed growth of the skeleton, broad chest, cardivascular abnormalities and gonadal dysgenesis. Women with this disorder are usually infertile due to ovarian failure. The clinical diagnosis was confirmed by the cytogenetic and by FISH analysis, which revealed the presence of only one X chromosome. Treatment may include human growth hormone and estrogen replacement therapy. On the other hand, thalassemias are genetic conditions that result from imbalance in the normal coordinated synthesis of the globin subunits that make up the hemoglobin tetramer, leading to decreased and defective production of hemoglobin. Beta thalassemia syndromes are hereditary disorders characterized by a genetic deficiency in the synthesis of beta-globin chains. Beta thalassemia is inherited in an autosomal recessive manner. Thalassemia minor usually presents as an asymptomatic mild microcytic anemia, but our case also had splenomegaly and required splenectomy.

    2006-01-01

    Full Text Available Beta-thalassemia is a genetic, red blood cell disorder affecting the beta-globin chain of the adult hemoglobin gene. This results in excess accumulation of unpaired alpha-chain gene products leading to reduced red blood cell life span and the development of severe anemia. Current treatment of this disease involves regular blood transfusion and adjunct chelation therapy to lower blood transfusion–induced iron overload. Fetal hemoglobin switching agents have been proposed to treat genetic blood disorders, such as sickle cell anemia and beta-thalassemia, in an effort to compensate for the dysfunctional form of the beta-globin chain in adult hemoglobin. The rationale behind this approach is to pair the excess normal alpha-globin chain with the alternative fetal gamma-chain to promote red blood cell survival and ameliorate the anemia. Reprogramming of differentiation in intact, mature, adult white blood cells in response to inclusion of monoclonal antibody CR3/43 has been described. This form of retrograde development has been termed “retrodifferentiation”, with the ability to re-express a variety of stem cell markers in a heterogeneous population of white blood cells. This form of reprogramming, or reontogeny, to a more pluripotent stem cell state ought to recapitulate early hematopoiesis and facilitate expression of a fetal and/or adult program of hemoglobin synthesis or regeneration on infusion and subsequent redifferentiation. Herein, the outcome of infusion of autologous retrodifferentiated stem cells (RSC into 21 patients with beta-thalassemia is described. Over 6 months, Infusion of 3-h autologous RSC subjected to hematopoietic-conducive conditions into patients with beta-thalassemia reduced mean blood transfusion requirement, increased mean fetal hemoglobin synthesis, and significantly lowered mean serum ferritin. This was always accompanied by an increase in mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, and mean

    2013-03-01

    Full Text Available Thalassemia intermedia is a genetically diverse group of diseases that is the result of an imbalance in the production of the alpha and beta chains with ensuing chronic hemolysis, ineffective erythropoiesis, and iron overload.Resulting complications include bone changes, hypercoagulability, and end-organ damage due to iron overload. This decade has witnessed major breakthroughs in the management of thalassemia. In this article, we examine these novelties in therapy including iron chelation therapy, stem cell transplant, and gene therapy.Iron chelation therapy has been revolutionized with the advent of deferasirox, a once-daily oral iron chelator, that has been shown to be safe and efficacious.Gene therapy was also at the core of this revolution with the discovery of novel gene elements and viral vectors allowing for better control and improved outcomes.

  20. Role of alpha-hemoglobin-stabilizing protein in normal erythropoiesis and beta-thalassemia.

    Hemoglobin (Hb) synthesis is coordinated by homeostatic mechanisms to limit the accumulation of free alpha or beta subunits, which are cytotoxic. Alpha hemoglobin-stabilizing protein (AHSP) is an abundant erythroid protein that specifically binds free alphaHb, stabilizes its structure, and limits its ability to participate in chemical reactions that generate reactive oxygen species. Gene ablation studies in mice demonstrate that AHSP is required for normal erythropoiesis. AHSP-null erythrocytes are short-lived, contain Hb precipitates, and exhibit signs of oxidative damage. Loss of AHSP exacerbates beta-thalassemia in mice, indicating that altered AHSP expression or function could modify thalassemia phenotypes in humans, a topic that is beginning to be explored in clinical studies. We used biochemical, spectroscopic, and crystallographic methods to examine how AHSP stabilizes alphaHb. AHSP binds the G and H helices of alphaHb on a surface that largely overlaps with the alpha1-beta1 interface of HbA. This result explains previous findings that betaHb can competitively displace AHSP from alphaHb to form HbA tetramer. Remarkably, binding of AHSP to oxygenated alphaHb induces dramatic conformational changes and converts the heme-bound iron to an oxidized hemichrome state in which all six coordinate positions are occupied. This structure limits the reactivity of heme iron, providing a mechanism by which AHSP stabilizes alphaHb. These findings suggest a biochemical pathway through which AHSP might participate in normal Hb synthesis and modulate the severity of thalassemias. Moreover, understanding how AHSP stabilizes alphaHb provides a theoretical basis for new strategies to inhibit the damaging effects of free alphaHb that accumulates in beta-thalassemia.

A total of 499 couples were referred to Gentec Lab., Lahore, from all over Pakistan for prenatal diagnosis of b-thalassemia. After counseling, chorionic villus sampling was done between 10-16 weeks of gestation. DNA analysis was done by Amplification Refractory Mutation System (ARMS) for type of mutation in the Armed Forces Institute of Pathology, Rawalpindi. Ethnicity, race and consanguineous relationship of parents was determined.b-thalassemia was prevalent in Punjabis (60.7%) followed by Saraikees (25.5%). Castewise it was most frequent in Rajputs followed by Jatts, Arain, Sheikhs and Pathans. 56.7% of the couples were first cousins and 19.8% were relatives. The commonest mutations were Frameshift 8-9 (Fr8-9) 33.5%, Intervening Sequence 1-5 (IVS 1-5) 17.2%, Fr4142 - 8%, IVS 1-1 - 5.2%, Deletion 619 (Del 619) 4.2% and Codon 5 (Cd 5) - 4.2%. In samples sent for analysis, 53.1% turned out to be carriers (trait), 25.3% were diseased (thalassemia major) and 21.6% were normal. P-value of all results was less than 0.001. In this series, the highest frequency was found in Punjabi Rajputs. The commonest mutation was Fr 8-9. Most parents were first cousins. Premarital thalassemia carrier testing can effectively reduce the disease. (author)

    Full Text Available 35 unrelated individuals were studied for characterization as either heterozygous or homozygous for beta-thalassemia. Molecular analysis was done by PCR/RFLP to detect the mutations most commonly associated with beta-thalassemia (β0IVS-I-1, β+IVS-I-6, and β039. In the patients who showed none of these mutations, the beta-globin genes were sequenced. Of the 31 heterozygous patients, 13 (41.9% had the β+IVS-I-6 mutation, 15 (48.4% the β0IVS-I-1 mutation, 2 (6.5% the β+IVS-I-110 mutation and 1 (3.2% the β+IVS-I-5 mutation. IVS-I-6 was detected in the four homozygotes. The mutation in codon 39, often found in previous studies in Brazil, was not detected in the present case. This is the first study aiming at identifying mutations that determine beta-thalassemia in the state of Rio Grande do Norte.

    Full Text Available Objective: Iron deficiency anemia (IDA and beta-thalassemia trait (ß-TT are the most common forms of microcytic anemia. This study was conducted to compare the validity of various discrimination indices in differentiating β-TT from IDA by calculating their sensitivity, specificity and Youden's index.Methods: Totally 323 subjects (173 children and 150 adults with microcytic anemia were involved in this study. We calculated 10 discrimination indices in all patients with IDA and β-TT. We divided the patients into two different groups as younger or older than 10 years. Results: None of the indices showed sensitivity and specificity of 100% in the patients older than 10 years, and in the patients younger than 10 years, only Shine & Lal index showed sensitivity close to 90% and specificity of 100%. The most accurate discriminative index for patients younger than 10 years was Shine & Lal and for those older than 10 years it was RDW index. According to Youden's index, Shine & Lal and RBC count showed the greatest diagnostic value in patients younger than 10 years and RDW and RBC count indices in those older than 10 years. Conclusion: None of the indices was completely sensitive and specific in differentiation between β-TT and IDA. Mean and median mean cell Hb density (MCHD were very close to normal values in both IDA and β-TT patients, but in the case of mean density of Hb/liter (MDHL, we found that the mean and median were significantly higher than normal values in β-TT and lower than normal values in IDA patients. In our study, Youden's index of RBC and Shine & Lal were the highest and most reliable indices in differentiating β-TT from IDA in the patients younger than 10 years. For patients older than 10 years, the most reliable discrimination indices were RBC and RDW.

    International Nuclear Information System (INIS)

    Objective: To share the preliminary data on stem cell transplantation in Pakistan. Results: Engraftment was achieved in all patients except one who required a second dose of bone marrow graft on day +21. Median time to achieve absolute neutrophil count of > 0.5 x 10/sup 9/ /l was 9.0 days (range 8 - 31 days) and platelet count of > 20 x 10/sup 9/ /l was 14 days (12 - 35 days). Acute GVHD was seen in 3 patients, one patient had grade IV gut GVHD; another patient had grade III gut GVHD while third patient had grade II skin GVHD. Median hospital stay was 29 days. Six patients were well and transfusion independent 3 to 36 months post transplant. One episode of primary graft failure required a second dose of bone marrow harvest. Another episode of graft rejection received two doses of donor lymphocytes infusion. There were 4 deaths due to grade IV gut GVHD because of uncontrolled systemic Candida infection and one due to hepatic veno-occlusive (VOD) disease. Conclusion: Allogeneic peripheral blood stem cell transplantation can be safely and economically carried out in Pakistan. Although there had been 4 deaths during 36 months follow-up, with increasing understanding and experience the outcome is expected to improve. (author)

    2005-03-01

    At age of 3.2 years routine blood analysis showed the presence of a beta-thalassemic trait with unexpected high level of serum iron and high transferrin saturation. Hematological follow-up confirmed the moderate degree of anemia and persisting high levels of iron indices throughout the years with a progressive increase of serum ferritin. At the age of 19 years the patient was diagnosed homozygous for HC63D HFE. The patient referred by us confirm the possibility of precocious alteration of iron indices in patients with heterozygosity for beta-thalassemia inherited together with HFE mutations. This observation suggests that any children with thalassemic trait with increased transferrin saturation and/or serum ferritin might be investigated for the presence of the hemocromatosis genes in order to detect the disease before any clinical manifestation and even before organ iron loading.

    Full Text Available Introduction: Beta thalassemia trait (BTT must be differentiated from iron deficiency anemia to avoid unnecessary iron therapy and for the prevention of thalassemia major by genetic counseling. In a tertiary care hospital, it is vital that the screening tool is not only sensitive but also specific so as to be cost effective and save time. Aim: The aim of this study was to evaluate the new Sehgal index and compare it to existing complete blood count-based indices for the best combination of sensitivity and specificity to predict BTT. Materials and Methods: Study was done in 2 phases - Phase 1: A retrospective analysis of 1022 consecutive high-performance liquid chromatography (HPLC cases from July 2008 to June 2011. Phase 2: A prospective analysis of 973 consecutive HPLC cases from July 1, 2011 to June 10, 2013 was done to confirm the results of Phase 1 and the applicability of the new Sehgal index. Results: Prevalence of BTT was 28.8% (294/1022 and 25.39% (247/973 in Phase 1 and Phase 2, respectively. Receiver operating characteristic-area under the curve and Youden index was highest for new Sehgal index, followed by Mentzers index <14. The prospective study shows results similar to those in Phase 1 confirming the superiority of the above two indices. Conclusion: Sehgal index and Mentzers index <14 showed the best combination of sensitivity and specificity in predicting BTT. The best indices or combination can be used as a "validated flag rule" in the analyzer middleware program in a hospital for identifying suspected cases of BTT.

    Red blood cell transfusion, main therapeutic modality of beta-thalassemia, leads to iron overload which may perturb several metabolic ways. The aim of this paper is to illustrate the uptake abnormalities observed on bone scan of thalassaemic patients and to discuss mechanisms of extraosseous accumulation of the radiopharmaceutical in this pathology. We report a 16-year-old child suffering from beta-thalassemia major undergoing transfusion therapy. A bone scan was indicated to look for osseous infection. This study revealed a little skeletal uptake and abnormal liver, splenic and renal accumulation. A repeat bone scan, performed three weeks later showed a better skeletal uptake which enabled the discovery of focal abnormalities and made the diagnostic easier. The effect of iron overload on radiopharmaceuticals uptake in bone scan is known since 1975. Dissociation of {sup 99m}Tc from the carrier ligand due to the presence of iron excess seems the most plausible hypothesis. Free {sup 99m}Tc can be bound to other tissular substrates which can explain extraosseous uptake. The normally available pool for bone is reduced and then the skeletal uptake decreased. This report limits considerably the sensitivity of the bone scan. A well-led iron chelation and eventually the use of diuretic drug may guarantee a better quality of bone scan images. (authors)

    Beta-thalassemia major (β-TM) is a genetic hemoglobin disorder characterized by an absent synthesis of globin chains that are essential for hemoglobin formation, causing chronic hemolytic anemia. Clinical management of thalassemia major consists in regular long-life red blood cell transfusions and iron chelation therapy to remove iron introduced in excess with transfusions. Iron deposition in combination with inflammatory and immunogenic factors is involved in the pathophysiology of cardiac dysfunction in these patients. Heart failure and arrhythmias, caused by myocardial siderosis, are the most important life-limiting complications of iron overload in beta-thalassemia patients. Cardiac complications are responsible for 71% of global death in the beta-thalassemia major patients. The aim of this review was to describe the most frequent electrocardiographic abnormalities and arrhythmias observed in β-TM patients, analyzing their prognostic impact and current treatment strategies.

Four process and outcome variables are reported here: (i) voluntary participation rates in the high-school cohort; (ii) uptake rates for the screening test; (iii) origin of carrier couples seeking the prenatal diagnosis option in the programs; and (iv) change in incidence of the two diseases. Between 1972 and 1992, we screened 14,844 Ashkenazi-Jewish students, identified 521 HexA-deficient carriers (frequency 1:28), reached 89% of the demographic cohort in the educational component of the program, and achieved 67% voluntary participation in the subsequent screening phase. The corresponding data for the beta-thalassemia program are 25,274 students (mainly of Mediterranean origin) representing 67% of the cohort with 61% voluntary participation in the screening phase (693 carriers; frequency 1:36). From demographic data, we deduce that virtually all the carriers identified in the high-school screening program remembered their status, had their partner tested if they did not already know they were a carrier couple, and took up the options for reproductive counseling/prenatal diagnosis. In Montreal, the current origin of all couples using prenatal diagnosis for Tay-Sachs and beta-thalassemia diseases is the corresponding genetic screening/testing program, whereas, at the beginning of the programs, it was always because there was a history of an affected person in the family. Incidence of the two diseases has fallen by 90%-95% over 20 years; the rare new cases are born (with two exceptions) outside the target communities or to nonscreened couples. PMID:8808593

    Full Text Available Objective: Growth retardation in children with b-thalassemia major is multifactorial. Some etiologies described for this condition are hemochromatosis, disturbed growth hormone (GH / insulin growth factor-1 (IGF-1 axis, undernutrition and hypermetabolism. It has also been proven that growth retardation is present in b-thalassemia major children despite regular transfusion and chelation. Our aim was to evaluate the level of IGF-1 in b-thalassemia minor subjects and compare it with that in healthy children. Material and Methods: Fifty children aged 6 months to 15 years with b-thalassemia minor (32 males, 18 females and 50 age- and sex-matched normal healthy children were selected. Medical history was taken and complete physical examination was done in each case; IGF-1 level was checked in all cases. This study was done in Shiraz, southern Iran, during 2005.Results: IGF-1 levels were significantly lower in b-thalassemia minor children than normal children (P = 0.015. This result demonstrates that some etiologies of growth failure in b-thalassemia major other than those described to date can exist, which may be shared with b-thalassemia minor in feature or may be transformed by genes that are either expressed or not.Conclusion: We conclude that in addition to that observed in b-thalassemia major, IGF-1 level is also decreased in b-thalassemia minor, and these two may have similar etiologies.

  2. Xmni polymorphism and disease severity in patients with beta thalassemia from northern Pakistan

    International Nuclear Information System (INIS)

    Thalassemia is a heterogeneous disorder and several genetic factors influence the severity of thalassemia. An accurate and early diagnosis of a mild thalassemia genotype helps to avoid unnecessary transfusion and its complications. The aim of this study is to identify the association between XmnI polymorphism and disease severity in patients with ?-thalassemia from northern Pakistan. Methods: The cross sectional study was conducted at the Department of Haematology, Armed Forces Institute of Pathology (AFIP) Rawalpindi, from September 2006 to June 2009. A total of 90 subjects including 30 with thalassemia major, 30 with thalassemia intermedia and 30 normal individuals were studied. DNA from each subject was tested for 15 ?-thalassemia mutations and the presence of XmnI polymorphism using Amplification Refractory Mutation System and Restriction Fragment Length Polymorphism respectively. Results: One normal and one thalassemia major subject were found to be positive for homozygous and heterozygous XmnI polymorphism respectively. Among the thalassemia intermedia group, XmnI polymorphism was found in 12/30 patients, of whom 10 were homozygous and 2 were heterozygous for it. Conclusion: XmnI polymorphism is an important genotypic factor in Pakistani population for making a prospective diagnosis of thalassemia intermedia and predicting the severity of the disease.

    Full Text Available Objective: Budd-Chiari syndrome is a multifactorial disease in which several prothrombotic disorders may predispose patients to the development of thrombosis at this uncommon location (hepatic veins. The aim of this study was to determine the prevalence and characteristics of inherited thrombophilia in Egyptian Budd-Chiari syndrome patients.Materials and Methods: The study included 47 Budd-Chiari syndrome patients (20 children and 27 adults. Genotyping of Factor V G1691A (Leiden, prothrombin G20210A (PT, and methylenetetrahydrofolate reductase C677T were performed using real-time PCR and fluorescence melting curve detection analysis.Results: Factor V Leiden was observed in 29 patients (61.7%. It is the only factor that caused Budd-Chiari syndrome in 18 of the patients and in 5 of the patients with inferior vena cava involvement. Myeloproliferative disease was noted in 12 (25.5% patients, antiphospholipid syndrome in 5 (10.6%, and Behcet’s disease in 3 (6.4%. Interestingly, 3 of the children with Budd-Chiari syndrome had lipid storage disease.Conclusion: Factor V Leiden was a major etiological factor in Egyptian Budd-Chiari syndrome patients, which may have been related to the high frequency of this mutation in the study region. Factor V Leiden was also a strong thrombophilic factor and the leading cause of inferior vena cava thrombosis in these patients. Lipid storage disease should be included as a risk factor for Budd-Chiari syndrome.

  9. Egyptian Constellations

    Lull, José; Belmonte, Juan Antonio

    The ancient Egyptians had a wide range of constellations, which populated the skies of ancient Egypt (see Chap. 133, "Orientation of Egyptian Temples: An Overview", 10.1007/978-1-4614-6141-8_146) for more than three millennia, whose knowledge has come to us through lists of stars and other representations which have mainly appeared in a dozen of coffins, a few clepsydrae, and a good set of astronomical ceilings. Hence, by making very simple assumptions and using the information provided by the ancient Egyptian sky-watchers, it is possible to uncover a great part of the ancient Egyptian firmament. This celestial tapestry was populated by the images of animals, symbols, and divinities that were most significant in understanding the Egyptian interpretation of the cosmos.

    Although the risk of transfusion-transmitted hepatitis has been recently reduced, transfusion-dependent beta-thalassemia patients may still develop liver disease due to viral infection or iron overload. We assessed the frequency and causes of liver dysfunction in a cohort of anti-hepatitis C virus (HCV) negative thalassemics. Of 1,481 thalassemics enrolled in 31 centers, 219 (14.8%) tested anti-HCV- by second-generation assays; 181 completed a 3-year follow-up program consisting of alanine-aminotransferase (ALT) measurement at each transfusion and anti-HCV determination by third-generation enzyme-immunoassay (EIA-3) at the end of study. Serum ferritin levels were determined at baseline and at the end of follow-up. Ten patients were anti-HCV+ by EIA-3 at the end of follow-up. Of them, seven were already positive in 1992 to 1993 when the initial sera were retested by EIA-3, one tested indeterminate by confirmatory assay, and two had true seroconversion (incidence, 4. 27/1,000 person years; risk of infection, 1/7,100 blood units, 95% confidence interval [CI], 1 in 2,000-1 in 71,000 units). At baseline, 67 of 174 thalassemics had abnormal ALT. Of those with normal ALT, seven subsequently developed at least one episode of moderate ALT increase (incidence, 24.6/1,000 person-years). All of the 20 patients with ferritin values >/=3,000 ng/mL had clinically relevant ALT abnormalities, as compared with 53 of 151 with <3,000 ng/mL (P < .005). Hepatic dysfunction is still frequent in thalassemics. Although it is mainly attributable to siderosis and primary HCV infection, the role of undiscovered transmissible agents cannot be excluded.

    Background: Carob - Ceratonia siliqua L., commonly known as St John's-bread or locust bean, family Fabaceae - is one of the most useful native Mediterranean trees. There is no data about the chromatography methods performed by high performance liquid chromatography (HPLC) for determining polyphenols in Egyptian carob pods. Objective: To establish a sensitive and specific liquid chromatography–electrospray ionization (ESI)-tandem mass spectrometry (MSn) methodology for the identification of the major constituents in Egyptian carob extract. Materials and Methods: HPLC with diode array detector and ESI-mass spectrometry (MS) was developed for the identification and quantification of phenolic acids, flavonoid glycosides, and aglycones in the methanolic extract of Egyptian C. siliqua. The MS and MSn data together with HPLC retention time of phenolic components allowed structural characterization of these compounds. Peak integration of ions in the MS scans had been used in the quantification technique. Results: A total of 36 compounds were tentatively identified. Twenty-six compounds were identified in the negative mode corresponding to 85.4% of plant dry weight, while ten compounds were identified in the positive mode representing 16.1% of plant dry weight, with the prevalence of flavonoids (75.4% of plant dry weight) predominantly represented by two methylapigenin-O-pentoside isomers (20.9 and 13.7% of plant dry weight). Conclusion: The identification of various compounds present in carob pods opens a new door to an increased understanding of the different health benefits brought about by the consumption of carob and its products. SUMMARY This research proposed a good example for the rapid identification of major constituents in complex systems such as herbs using sensitive, accurate and specific method coupling HPLC with DAD and MS, which facilitate the clarification of phytochemical composition of herbal medicine for better understanding of their nature and

    Full Text Available The rate of erythrocyte alloimmunization in tranfusion-dependent patients can reach 50%, although the frequency of clinically relevant antibodies in transfused patients is not fully known, it is estimated that about 1% of patients are sensitized to each unit of transfused RBCs. The aim of this study is to report the case of  an 11-year-old girl with ?-thalassemia major, chronically transfused, which was detected in pre-transfusion protocol, the presence of two rare anti-erythrocyte antibodies: anti-Colton b (anti-Cob and anti-Lutheran 14 (anti-Lu14. To survey the clinical and laboratory patient history, research records filed in the archives of the university hospital in which the patient is monitored system was performed. The phenotyping erythrocyte in multitransfused patients is essential to decrease the risk of complications due to alloimmunization and estimate the availability of compatible blood. Thus, the report of this case may contribute to increase knowledge about of the real frequency of uncommon anti-erythrocyte antibodies in thalassemic patients.

    Full Text Available Beta (β thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of β-globin chains. In the homozygous state, β-thalassemia (i.e., thalassemia major causes severe transfusion-dependent anemia. Inherited β-thalassemia syndromes cause high degree of hemolytic anemia, recurrent fever, clinical jaundice, frequent infections, bossing of cheek bones, growth retardation, splenomegaly, etc. and are responsible for high infant morbidity, mortality and fetal wastage in India. The victims include the infants, growing children, adolescent girls, pregnant women and a large chunk of ignorant people. In view of heavy genetic load, frequent requirement of blood transfusions, high cost of treatment and management, physical trauma, and mental and psychological harassment to the patients and their families, it has been realized that preventive community health and genetics approach is the most suitable for India. After carrier detection, prenatal diagnosis, and genetic couselling are the important options for couples at high risk for β-thalassemia. A prerequisite for successful prevention and intervention approach in India is the health education, bringing public awareness, sensitization, and community screening for the identification of heterozygotes or carriers in the concerned community. Some suggestions for the prevention of β-thalassemia in the vulnerable communities of India have been over emphasized for amelioration.β地中海贫血综合症是一簇遗传性异常,其特点是β球蛋白链接合处基因缺失。β地贫(或重型地贫)在纯和状态下导致严重的输液依赖型贫血症。遗传性的β地贫综合症引起严重的溶血性贫血、回归热、显性黄疸、常见感染、疼痛危象、颊骨浮肿、生长迟缓、脾肿大等症状,这导致在印度出现婴儿高发病率、死亡率和胎儿夭折。其受害人群包括婴儿、发

    By performing regular blood transfusion and iron chelation therapy, most patients with beta thalassemia major (BTM) now survive beyond the third decade of life. Liver disease is becoming an important cause of morbidity and mortality in these patients. Chronic hepatitis and/or severe iron overload are both important causes of liver pathology. Iron chelation with desferrioxamine (DFO) reduces excessive body iron, but its efficacy is limited by poor compliance and dose related toxicity. The rece...

    2003-01-01

    Our objective was to study, in thalassemic patients, if hepatic siderosis evaluated by MRI could predict the pituitary iron overload. In 36 thalassemic patients (age range 6-44 years, mean age 21.7 years) the liver/fat ratio (L/F), the pituitary/fat ratio (P/F), the liver and pituitary T2 relaxation times were evaluated, by using a multiecho spin-echo sequence. Serum ferritin levels were measured and an extensive endocrine evaluation was performed. The L/F, the P/F and pituitary T2 showed a good correlation with serum ferritin (r=-0.55, r=-0.55 and r=-0.53, respectively; p<0.01). Liver T2 did not show significant correlation with serum ferritin. The variability of L/F explained only the 10.8% of the variability of pituitary T2 and of the P/F. When ferritin was added to the model it predicted only the 26.85% and the 30.8% of the variability of pituitary T2 and of the P/F, respectively. The P/F and pituitary T2 were lower in patients with hypogonadotropic hypogonadism (group 1) compared with those without pituitary dysfunction (group 2). No significant differences of L/F were found between the two groups. Hepatic iron overload evaluated by MR is a poor predictor of pituitary siderosis. The MR studies of the pituitary gland might be necessary to evaluate the pituitary iron overload. (orig.)

    Full Text Available β-thalasemia major (β-TM patients often suffer from various vascular complications together with increased oxidative stress. Hyperhomocysteinemia (Hhcy has been defined as a risk factor for these complications. Genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR C677T has been shown to cause Hhcy particularly in individuals with low B-vitamins. However, the status of homocysteine (hcy in β-TM has not yet been adequately defined.To evaluate the genetic polymorphism of MTHFR C677T among β-TM patients and its prospective contribution to Hhcy and related oxidative changes.Genotyping for MTHFR C677T was done by PCR-RFLP technique. Plasma hcy, vitamin B12, folate, malondialdehyde (MDA, total antioxidant capacity (TAC, oxidized low density lipoprotein (oxLDL, total nitric oxide (NOx and lipid profile were determined in 66 β-TM patients and 66 control subjects of matched age and sex.The prevalence of MTHFR 677TT genotype was significant among β-TM patients (12% compared to (3% controls (OR = 4.9, 95%CI:1.2-24.2,P = 0.03. A strong association between Hhcy and MTHFR TT genotype was observed (OR = 7.7, 95%CI:2.8-20.9 where all β-TM patients with TT genotype were hyperhomocystienemic (≥ 15 μmol/l and having sub-optimal folate level than those with CT or CC genotypes. Hyperhomocystienemic patients have suffered from increased oxidative stress characterized by significant increase in plasma MDA and oxLDL, and a significant reduction of plasma TAC and total NOx. Lipid profile of those patients was severely affected indicated by reduction in HDL and HDL/LDL and elevation in atherogenic index as compared with CC genotype. Other measured parameters were not significantly different among β-TM patients with different MTHFR genotypes.This study suggests that Egyptian β-TM patients with MTHFR 677TT genotype could be at increasing risk of developing Hhcy particularly with folate deficiency. This state of Hhcy may account potentially for most

    Hb F-Malta-I [Ggamma117(19)His-->Arg, CAT-->CGT] is a stable and benign variant of Hb F found in 1.8% of Maltese newborn. We studied 120 Hb F-Malta-I heterozygotes and four Hb F-Malta-I homozygotes. The mean proportion of Ggamma-F-Malta-I in Hb F was 0.26 +/- 0.03 for the Hb F-Malta-I heterozygotes and 0.58 +/- 0.06 for the Hb F-Malta-I homozygotes. The Hb F-Malta-I allele was shown to occur on a background of the common Mediterranean haplotype Va [+ + - - - - - + + -]. Furthermore, the common Mediterranean haplotypes Va, IIIb [- + + + - + + + + -], I [+ + - - - - - + + +] and II [- + - + + - + + + +] accounted for most (66.2%) of the wild-type alleles among the tested Hb F-Malta-I heterozygotes. Different genotypes at the 5' epsilon HincII, Ggamma and Agamma HindIII, and 3'psibeta HincII sites (but not at the 5' Ggamma XmnI site) were found to be linked to significant variations in the proportion of Ggamma-F-Malta-I and Ggamma-globins in the Hb F of newborn Hb F-Malta-I heterozygotes. Moreover, the 5' Ggamma XmnI site was found to be associated with variations in Hb F and Ggamma-globin levels in a population of adult Maltese beta-thalassemia (thal) homozygotes. This implies that a determinant linked to the XmnI site which effects Ggamma-globin gene expression is active in anemic adults but not in normal infants.

    Full Text Available Abstract Background Beta thalassemia is the most frequent genetic disorder of haemoglobin synthesis in Pakistan. Recurrent transfusions lead to iron-overload manifested by increased serum Ferritin levels, for which chelation therapy is required. Findings The study was conducted in the Pediatric Emergency unit of Civil Hospital Karachi after ethical approval by the Institutional Review Board of Dow University of Health Sciences. Seventy nine cases of beta thalassemia major were included after a written consent. The care takers were interviewed for the socio-demographic variables and the use of Desferrioxamine therapy, after which a blood sample was drawn to assess the serum Ferritin level. SPSS 15.0 was employed for data entry and analysis. Of the seventy-nine patients included in the study, 46 (58.2% were males while 33 (41.8% were females. The mean age was 10.8 (± 4.5 years with the dominant age group (46.2% being 10 to 14 years. In 62 (78.8% cases, the care taker education was below the tenth grade. The mean serum Ferritin level in our study were 4236.5 ng/ml and showed a directly proportional relationship with age. Desferrioxamine was used by patients in 46 (58.2% cases with monthly house hold income significant factor to the use of therapy. Conclusions The mean serum Ferritin levels are approximately ten times higher than the normal recommended levels for normal individuals, with two-fifths of the patients not receiving iron chelation therapy at all. Use of iron chelation therapy and titrating the dose according to the need can significantly lower the iron load reducing the risk of iron-overload related complications leading to a better quality of life and improving survival in Pakistani beta thalassemia major patients.

    Splenectomy is a recognized cause of portal vein thrombosis. Thirty-six β-thalassemia major (β-TM) patients were followed up for 36 months to evaluate changes in D-dimer levels (as a possible marker for thrombosis development) and portal vein status (by portal duplex ultrasound) at both early and late postlaparoscopic splenectomy periods. They were classified into group I if they were splenectomized in the study period (n = 12), or group II if they were splenectomized during the 5 years preceding the period (n = 24). In group I, D-dimer was measured 5 times: 1 day presplenectomy, the 1st week, 6th week, and 6th month postsplenectomy, and at the study end, whereas in group II, D-dimer was measured twice: at the study entry and end. Portal duplex was done 1 week postsplenectomy (group I) and at study end in both groups. Presplenectomy D-dimer levels in group I were significantly higher compared with the 6th month (P = .042) and study end (P = .03), whereas 1st week (postsplenectomy) D-dimer levels had a high mean of 3497.3 ng/mL, lowered at the 6th week (P = .017), at the 6th month (P = .008), and at study end (P = .005). D-dimer levels in group II showed no difference between study entry and end (P = .104). Portal vein "diameter and flow" were within normal findings in both groups. In this 3-year prospective study, a subclinical hypercoagulable state was detected 1 day prior to splenectomy and in the early postsplenectomy period, as evidenced by high D-dimer levels. Laparoscopic splenectomy was not associated with portal venous thrombosis either clinically or by duplex sonography. PMID:22475301

    Vitamin D is critical for calcium, phosphate homeostasis and for mineralization of the skeleton, especially during periods of rapid growth. Vitamin D Deficiency leads to rickets (in children) and osteomalacia (in adults). Expression and activation of the vitamin D receptor (VDR) are necessary for the effects of vitamin D, in which several single nucleotide polymorphisms have been identified especially (FokI, BsmI). In this study serum 25 (OH) vitamin D3 levels were estimated by Enzyme Linked Immunosorbent Assay [ELISA], VDR (FokI, BsmI) gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism assay [PCR-RFLP].Serum levels of calcium, phosphorus, alkaline phosphatase and ferritin were determined in 50 Pediatrics beta thalassemia major patients and 60 controls. Patients had significantly lower serum calcium (p serum vitamin D3 (p 30 ng/ml). Patients harboring mutant (Ff,ff) and wild (BB) genotypes were associated with lower serum calcium (p = 0.08, 0.02) respectively, lower vitamin D3 levels (p  0.05). In conclusion, these results suggest that the VDR (FokI, BsmI) gene polymorphisms influence vitamin D status, (Ff,ff), BB genotypes had lower vitamin D levels, so they might influence risk of development of bone diseases in beta thalassemia major.

    In this study, we investigated distinctions among the diversity of religious traditions represented by Lebanese and Egyptian Muslim high school students regarding their understanding and acceptance of biological evolution and how they relate the science to their religious beliefs. We explored secondary students' conceptions of evolution among members of three Muslim sects—Sunni, Shiite, and Druze—in two cultural contexts; one in which the overwhelming majority of the population is Muslim (Egypt) and another in which there is a sizable Christian community (Lebanon). Data were collected via surveys that examined students' scientific and religious understandings of evolution among 162 Egyptian students (all Sunni Muslims; 63% females and 37% males) and 629 Lebanese students (38.5% Sunni, 38% Shiite, and 23.5% Druze; 49% females and 51% males). Additional data were collected via semi-structured interviews with 30 Lebanese students to allow triangulation of data for accuracy and authenticity. Results indicate that many Egyptian and Lebanese Muslim students have misconceptions about evolution and the nature of science which often lead to rejection of evolution. Also, Lebanese Sunni and Shiite students and Egyptian Sunni students tend to exhibit high levels of religiosity, and these students report that their religious beliefs influence their positions regarding evolution. Finally, Sunni and Shiite Lebanese students have religious beliefs, conceptions of evolution, and positions regarding evolution similar to those of Sunni Egyptian students. These conceptions and positions, however, are substantially different from those of Druze Lebanese students.

    Full Text Available University College London houses one of the world’s most important collections of ancient Egyptian material, the majority excavated by Flinders Petrie, his students and his successors in the late 19th and early 20th centuries. It is a museum of archaeology that helps to explain the development of a discipline that was in its infancy when Petrie worked in Egypt over a century ago. It is a teaching collection, its densely packed cases entrancing, and sometimes intimidating, visitors who rave about its old-fashioned feel, but it is anything but frozen in time.

  9. Effects of blood transfusion on exercise capacity in thalassemia major patients.

    Daniela Benedetto

    Full Text Available Anemia has an important role in exercise performance. However, the direct link between rapid changes of hemoglobin and exercise performance is still unknown.To find out more on this topic, we studied 18 beta-thalassemia major patients free of relevant cardiac dysfunction (age 33.5±7.2 years,males = 10. Patients performed a maximal cardiopulmolmonary exercise test (cycloergometer, personalized ramp protocol, breath-by-breath measurements of expired gases before and the day after blood transfusion (500 cc of red cell concentrates. After blood transfusion, hemoglobin increased from 10.5±0.8 g/dL to 12.1±1.2 (p<0.001, peak VO2 from 1408 to 1546mL/min (p<0.05, and VO2 at anaerobic threshold from 965 to 1024mL/min (p<0.05. No major changes were observed as regards heart and respiratory rates either at peak exercise or at anaerobic threshold. Similarly, no relevant changes were observed in ventilation efficiency, as evaluated by the ventilation vs. carbon dioxide production relationship, or in O2 delivery to the periphery as analyzed by the VO2 vs. workload relationship. The relationship between hemoglobin and VO2 changes showed, for each g/dL of hemoglobin increase, a VO2 increase = 82.5 mL/min and 35 mL/min, at peak exercise and at anaerobic threshold, respectively. In beta-thalassemia major patients, an acute albeit partial anemia correction by blood transfusion determinates a relevant increase of exercise performance, observed both at peak exercise and at anaerobic threshold.

    Full Text Available Background : Children suffering from beta-thalassemia major require repeated blood transfusions which may be associated with dangers like iron overload and contraction of infections such as HIV, HCV, and HBsAg which ultimately curtail their life span. On the other hand, inadequate transfusions lead to severe anemia and general fatigue and debility. Materials and Methods: Data were obtained from 142 beta-thalassemia major patients aged 3 years or more receiving regular blood transfusions at a transfusion centre in Western India from 1 April 2009 to 30 June 2009. The clinical data and laboratory results were subsequently analyzed. Results: Of the 142 patients, 76 (53.5% were undertransfused (mean Hb <10 gm%. 96 (67% of the patients were taking some form of chelation therapy but out of them only 2 (2% were adequately chelated (S. ferritin <1000 ng/ml. 5 (3.5% of the patients were known diabetics on insulin therapy. 103 (72% of the patients were retarded in terms of growth. The prevalence of transfusion-transmitted infections (TTIs such as HCV, HIV, and HBsAg was respectively 45%, 2%, and 2%, with the prevalence of HCV being significantly more than the general population. The HCV prevalence showed positive correlation with the age of the patients and with the total no of blood transfusions received. As many as 15% (6 out of 40 children who were born on or after 2002 were HCV positive despite the blood they received being subjected to screening for HCV. Conclusions: The study suggests the need to step up the transfusions to achieve hemoglobin goal of 10 gm% (as per the moderate transfusion regimen and also to institute urgent and effective chelation measures with the aim of keeping serum ferritin levels below 1000 ng/ml to avoid the systemic effects of iron overload. In addition, strict monitoring of the children for endocrinopathy and other systemic effects of iron overload should be done. Rigid implementation of quality control measures for the

  11. [Ancient Egyptian Odontology].

    1999-01-01

    In ancient Egypt during the reign of Pharaoh Djoser, circa 2650 BC, the Step Pyramid was constructed by Imhotep. He was later worshiped as the God of Medicine. One of his contemporaries was the powerful writer Hesy who is reproduced on a panel showing a rebus of a swallow, a tusk and an arrow. He is therefore looked upon as being the first depicted odontologist. The art of writing begun in Egypt in about 3100 BC and the medical texts we know from different papyri were copied with hieratic signs around 1900-1100 BC. One of the most famous is the Papyrus Ebers. It was purchased by professor Ebers on a research travel to Luxor in 1873. Two years later a beautiful facsimile in color was published and the best translation came in 1958 in German. The text includes 870 remedies and some of them are related to teeth and oral troubles like pain in the mouth, gingivitis, periodontitis and cavities in the teeth. The most common oral pain was probably pulpitis caused by extreme attrition due to the high consumption of bread contaminated with soil and/or quern minerals. Another text is the Papyrus Edwin Smith with four surgical cases of dental interest. The "toothworms" that were presumed to bring about decayed teeth have not been identified in the medical texts. It was not until 1889 W.D. Miller presented a scientific explanation that cavities were caused by bacteria. In spite of extensive research only a few evidence of prosthetic and invasive treatments have been found and these dental artifacts have probably been made post mortem. Some of the 150 identified doctors were associated with treatments of disorders of the mouth. The stele of Seneb from Sa'is during the 26th dynasty of Psamtik, 664-525 BC, shows a young man who probably was a dental healer well known to Pharaoh and his court. Clement of Alexandria mentions circa 200 AD that the written knowledge of the old Egyptians was gathered in 42 collections of papyri. Number 37-42 contained the medical writings. The

    1988-01-01

    Egyptian Blue is a synthesized crystalline pictorial pigment with formula CaCuSi/sub 4/O/sub 10/. It has been used in Egypt and Mesopotamia from the 3rd millenium B.C. A preliminary experiment on a recently synthesized sample showed that this pigment is thermoluminescent after ..beta.. irradiation (/sup 90/Sr). As the signal intensity grows linearly with the administered dose within the temperature range commonly used in TL dating, we have been looking for this phenomenon from archaeological pigments. It was encountered with two samples found in excavation. From its intensity and stability we concluded that Egyptian Blue can be dated using TL. This first and positive result encouraged us to extend the method to other types of mineral pigments synthesized by early man, and to suggest that it may be used for direct dating of ancient murals.

    Full Text Available In July and September 2007, miners working in Kitaka Cave, Uganda, were diagnosed with Marburg hemorrhagic fever. The likely source of infection in the cave was Egyptian fruit bats (Rousettus aegyptiacus based on detection of Marburg virus RNA in 31/611 (5.1% bats, virus-specific antibody in bat sera, and isolation of genetically diverse virus from bat tissues. The virus isolates were collected nine months apart, demonstrating long-term virus circulation. The bat colony was estimated to be over 100,000 animals using mark and re-capture methods, predicting the presence of over 5,000 virus-infected bats. The genetically diverse virus genome sequences from bats and miners closely matched. These data indicate common Egyptian fruit bats can represent a major natural reservoir and source of Marburg virus with potential for spillover into humans.

  17. Some endocrinal aspects of pancreas in beta thalassemia

    International Nuclear Information System (INIS)

    The study was carried out to evaluate endocrinal aspects of the pancreas in thalassemia children, ages 5 - 10 years maintained under either regular or irregular iron chelation therapy. A matched control on healthy children, was included for comparison. As regards laboratory findings, fasting and post prandial blood sugar was significantly elevated in thalassemia children than the control and serum insulin was significantly lower in the irregular iron chelation group than both in the regular one and in the control group. Most cases of diabetic thalassemia children clinically and biochemically were of irregular iron chelation and with older age. They were frequently higher transfused. There is significant rise of serum ferritin in diabetic group than in diabetic thalassemia children. In conclusion, pancreatic dysfunction can be detected in thalassemia children, but regular iron chelation can reduce its occurrence. 10 tabs

    Egyptian jojoba seeds newly cultivated in Ismailia desert in Egypt promoted us to determine its lipid components. Fatty alcohols, fatty acids, wax esters and sterols patterns were determined by capillary GLC whereas, tocopherols profile, isopropenoid alcohols and sterylglycosides were determined by HPLC. The Egyptian seeds are rich in wax esters (55 %) with fatty alcohols C20:1 and C22:1 as major components and amounted to 43.0 % and 45.6 % respectively followed by C24:1 and C18:1(9.6 % and 1.3 % respectively). The fatty acids profile showed that C20:1 is the major constituent (60 %) followed by C18:1 and C22:1 (14.5 and 11.8 % respectively) whereas C24:1 was present at low concentration amounted to 1.6 %. In addition, the Egyptian jojoba wax contained C18:2 fatty acid at a level of 8.7 %. Wax esters composition showed that the local wax had C42 and C40 esters as major components amounted to 51.1 and 30.1 % respectively. Also, it had C44 and C38 at reasonable amounts (10.0 and 6.3 % respectively). Whereas C36 and C46 were present at lower concentrations amounted to 1.4 and 1.1 respectively. The sterols analysis showed the presence of campe-, stigma-, beta-sito-, and isofuco- sterol amounting to 18.4 %, 6.9 %, 68.7 %, and 6.0 % respectively. The tocopherols pattern revealed that the local seed wax contained gamma-tocopherol as major constituent (79.2 %) followed by alpha-tocopherol (20.3 %). beta-tocopherol as well as delta-tocopherol were found as minor constituents. The isopropenoid alcohols and the sterylglycosides (free and acylated) were not detected. The wax is proposed to be used in oleo chemistry and cosmetics.

  5. Radiological assessment of the Egyptian Mediterranean coast

    International Nuclear Information System (INIS)

    On the basis of extensive sampling, gamma spectrometry, laboratory analyses, data evaluation and comparison with the reference data, the following assessment has been carried out. The radiological assessment has been done for a wide scale study area (about 1100 km) from El- Salloum in the west of the Mediterranean coast of Egypt to El-Arish in the east. The environmental radiological assessment steps are based on the criteria previously mentioned. The sources of radioactivity possibly reach the Egyptian Mediterranean coast can be summarized as: primordial and radiogenic radionuclides (e.g. 40K, 238U and 232Th series), cosmic rays and cosmogenic radionuclides (e.g. 7Be), fertilizers (e.g. superphosphate), black sand (transported by Nile River), fallout (either from nuclear testing or Chernobyl), seawater currents (transported either natural or man-made), Suez Canal (subject to receive a radioactive releasing and effluents from either nuclear power ships or submarines passes through the canal), biological migration and sedimentary longshore movement (e.g. Anguilla anguilla), atmospheric radioactivity (e.g. 222Rn and its daughters), domestic and medical sewage (minor source, short half-life), depleted uranium dust (possibly), satellite and aircraft accident (accidentally) and rarely loss of industrial radioactive source (incidentally). El-Salloum, Rashid and El-Gamil have been considered as concentrated basins for the majority of the radioisotopes. This suggestion was due to the special topographical features of these three stations, which make the accumulation of the radioactive isotopes possible. Calculations of outdoor absorbed dose rate for human population at all stations under investigation from 238U, 232Th and 40K were carried out. The calculated absorbed dose rate has been distinguished the coast into normal areas and Rashid black sand area as high background area. The range of calculated dose was 8.39-38.5 μGy/h.

    Full Text Available Abstract Background Studies have shown that research participants fail to appreciate the difference between research and medical care, labeling such phenomenon as a "therapeutic misconception" (TM. Since research activity involving human participants is increasing in the Middle East, qualitative research investigating aspects of TM is warranted. Our objective was to assess for the existence of therapeutic misconception amongst Egyptians. Methods Study Tool: We developed a semi-structured interview guide to elicit the knowledge, attitudes, and perspectives of Egyptians regarding medical research. Setting: We recruited individuals from the outpatient settings (public and private at Ain Shams University in Cairo, Egypt. Analysis: Interviews were taped, transcribed, and translated. We analyzed the content of the transcribed text to identify the presence of a TM, defined in one of two ways: TM1 = inaccurate beliefs about how individualized care can be compromised by the procedures in the research and TM2 = inaccurate appraisal of benefit obtained from the research study. Results Our findings showed that a majority of participants (11/15 expressed inaccurate beliefs regarding the degree with which individualized care will be maintained in the research setting (TM1 and a smaller number of participants (5/15 manifested an unreasonable belief in the likelihood of benefits to be obtained from a research study (TM2. A total of 12 of the 15 participants were judged to have expressed a TM on either one of these bases. Conclusion The presence of TM is not uncommon amongst Egyptian individuals. We recommend further qualitative studies investigating aspects of TM involving a larger sample size distinguished by different types of illnesses and socio-economic variables, as well as those who have and have not participated in clinical research.

    Egyptian phosphorites from Abu Tartur (Western Desert), El Mahamide mine (Nile Valley) and Rabah mine (Eastern Desert) show variable degrees of relative REE enrichment.Black plateau phosphorites of Abu Tartur are substantially enriched in REE as compared to the Red Sea and Nile Valley phosphorites. P-rich organic matter from the Abu Tartur and Rabah mines recorded negative Ce and positive Eu anomalies. Positive Eu anomaly reveals an anoxic event prior to the phase of Late Cretaceous phosphate formation. Ce is a redox indicator. Mixing of sea water and upwelling during the Late Cretaceous was responsible for the recording of positive Eu and negative Ce anomalies in the Egyptian phosphorites.

    This article describes the evolution of Egyptian neurosurgery. It highlights the experiences of the ancient Egyptians in treatment of the central nervous system diseases. These experiences were documented through their papyrus writings and their drawings over the walls in ancient temples. The aim of this article is not only to search for the roots of neurosurgery in Egypt but also to showcase the present and future status of neurosurgery. Neurosurgery developed as a specialty earlier in Egypt and has led the development of this specialty in Africa and the Middle East. It is worthwhile tracing the history of neurosurgery of past civilizations, ancient medicine, and the work of pioneers. PMID:20166531

    Full Text Available The identification of species constitutes the first basic step in phylogenetic studies, biodiversity monitoring and conservation. DNA barcoding, i.e. the sequencing of a short standardized region of DNA, has been proposed as a new tool for animal species identification. The present study provides an update on the composition of shark in the Egyptian Mediterranean waters off Alexandria, since the latest study to date was performed 30 years ago, DNA barcoding was used in addition to classical taxonomical methodologies. Thus, 51 specimen were DNA barcoded for a 667 bp region of the mitochondrial COI gene. Although DNA barcoding aims at developing species identification systems, some phylogenetic signals were apparent in the data. In the neighbor-joining tree, 8 major clusters were apparent, each of them containing individuals belonging to the same species, and most with 100% bootstrap value. This study is the first to our knowledge to use DNA barcoding of the mitochondrial COI gene in order to confirm the presence of species Squalus acanthias, Oxynotus centrina, Squatina squatina, Scyliorhinus canicula, Scyliorhinus stellaris, Mustelus mustelus, Mustelus punctulatus and Carcharhinus altimus in the Egyptian Mediterranean waters. Finally, our study is the starting point of a new barcoding database concerning shark composition in the Egyptian Mediterranean waters (Barcoding of Egyptian Mediterranean Sharks [BEMS], http://www.boldsystems.org/views/projectlist.php?&#Barcoding%20Fish%20%28FishBOL%29.

    Madkour, Samia A; Laurence, J A

    2002-01-01

    The aim of this study was to test and select one or more highly sensitive, specific and environmentally successful Egyptian bioindicator plants for ozone (O3). For that purpose more than 30 Egyptian species and cultivars were subjected to extensive screening studies under controlled environmental and pollutant exposure conditions to mimic the Egyptian environmental conditions and O3 levels in urban and rural sites. Four plant species were found to be more sensitive to O3 than the universally used O3-bioindicator, tobacco Bel W3, under the Egyptian environmental conditions used. These plant species, jute (Corchorus olitorius c.v. local), clover (Trifolium alexandrinum L. c.v. Masry), garden rocket (Eruca sativa c.v. local) and alfalfa (Medicago sativa L. c.v. local), ranked in order of decreasing sensitivity, exhibited typical O3 injury symptoms faster and at lower 03 concentrations than Bel W3. Three variables were tested in search of a reliable tool for the diagnosis and prediction of O3 response prior to the appearance of visible foliar symptoms: pigment degradation, stomatal conductance (g(s)) and net photosynthetic CO2 assimilation (Pnet). Pigment degradation was found to be unreliable in predicting species sensitivity to O3. Evidence supporting stomatal conductance involvement in 03 tolerance was found only in tolerant species. A good correlation was found between g(s), restriction of O3 and CO2 influx into the mesophyll tissues, and Pnet. Changes in Pnet seemed to depend largely on fluctuations in g(s).

    2013-12-01

    Full Text Available The One of the most challenging problems that encounter the Egyptian society is the lack of significant health care in the rural areas. This problem leads to more severe problems that face the society; the patients from the different rural areas needs to travel to the Egyptian capital where the most experienced physicians are available. This will make overhead not only on the patient budget but on the country budget since the focus on the capital makes a severe traffic problem which threaten most of the economic sectors. The telemedicine is considered one of the most important solutions that could mitigate the accumulated problems of lack of experienced physicians in the Egyptian rural areas. The application of the telemedicine encounters several challenges in Egypt; the lack in the experience in dealing with the telemedicine in these areas and the problem of insufficient medical experts that could fulfil the gab. In this paper, a new ICT-based telemedicine system is proposed to serve the Egyptian society. The portal is already released and snapshots are included

    The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

    Full Text Available Discerning the genetic diversity of any crop species provides insight into the strength of an applied breeding program and directs future breeding strategies aimed at long-term genetic gain and minimized genetic vulnerability. The number and abundance of ancestral parents present in the pedigree of crop cultivars can provide an average estimation of the depth of the genetic base of the overall crop improvement program. The objectives of this study were to estimate (1 the genetic similarity among 33 Egyptian wheat (Triticum aestivum L. cultivars and different eras of release (1947-2004 and productivity groups based on COP values, and (2 the relative genetic contribution and abundance of ancestral parents from different geographical origins to the total gene pool of Egyptian wheat cultivars. Broad genetic diversity was observed among 33 Egyptian cultivars with average COP value of 0.11 and large numbers of ancestral parents (155 landraces traced to 31 countries. The genetic base ranged from very low in pre 1960’s cultivars such as ‘Giza 139’ (with only 3 landraces in the background to very high in modern cultivars such as ‘Gemmeiza-7’ (with 73 landraces in the background. ‘Hindi-62’, ‘Red Fife’, ‘Hard Red Calcutta’ and ‘Akagomughi’ were the major ancestors with 6, 5, 4, and 4% of total genetic contribution to the Egyptian wheat gene pool, respectively. Egypt, United States of America, Kenya and Ukraine were the major source countries with 16, 11, 9 and 7% of total genetic contribution to this gene pool, respectively. Though Marquis-Thatcher germplasm from North America has the greatest influence on overall Egyptian cultivars, Mexican-based sources of dwarfing and high yield, derived from ancestors such as ‘Akagomughi’ and ‘Daruma’ and exploited by the International Maize and Wheat Improvement Center (CIMMYT, were very prominent in Egyptian cultivars post 1970’s.

    Physics is a dynamic, global field. Progress in research motivates scientists to explore new areas and find useful applications for their work. Femtosecond ultrashort pulsed lasers and progress in nanostructures to study the properties of extremely dense matter, as well as one-dimensional materials, are two examples of innovations that encourage students and scientists—male and female—to pursue physics. Young Egyptian women's contributions to physics grew from 46% in 2003 to 69% in 2008. This paper discusses the role of women in physics in Egypt; presents statistics regarding their contributions and presence at Egyptian universities and institutes; and gives information about their decision making leadership roles. Ideas, applicable in Egypt as well as in developing countries, to address problems facing women are raised.

  3. The thermoluminescence (TL) of Egyptian Blue

    International Nuclear Information System (INIS)

    Egyptian Blue is a synthesized crystalline pictorial pigment with formula CaCuSi4O10. It has been used in Egypt and Mesopotamia from the 3rd millenium B.C. A preliminary experiment on a recently synthesized sample showed that this pigment is thermoluminescent after β irradiation (90Sr). As the signal intensity grows linearly with the administered dose within the temperature range commonly used in TL dating, we have been looking for this phenomenon from archaeological pigments. It was encountered with two samples found in excavation. From its intensity and stability we concluded that Egyptian Blue can be dated using TL. This first and positive result encouraged us to extend the method to other types of mineral pigments synthesized by early man, and to suggest that it may be used for direct dating of ancient murals.

    The Egyptian swift Rock Pigeon is a breed of fancy pigeon developed over many years of selective breeding. In this work, we report the complete mitochondrial genome sequence of Egyptian swift Rock Pigeon. The total length of the mitogenome was 17,239 bp and its overall base composition was estimated to be 30.2% for A, 24.0% for T, 31.9% for C and 13.9% for G, indicating an A-T (54.2%)-rich feature in the mitogenome. It contained the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region (D-loop region). The complete mitochondrial genome sequence of Egyptian swift Rock Pigeon would serve as an important data set of the germplasm resources for further study.

  5. Egyptian plant species as new ozone indicators

    International Nuclear Information System (INIS)

    Of more than 30 species of plants from Egypt screened for sensitivity to ozone, four were found to be suitable for use as bioindicators. - The aim of this study was to test and select one or more highly sensitive, specific and environmentally successful Egyptian bioindicator plants for ozone (O3). For that purpose more than 30 Egyptian species and cultivars were subjected to extensive screening studies under controlled environmental and pollutant exposure conditions to mimic the Egyptian environmental conditions and O3 levels in urban and rural sites. Four plant species were found to be more sensitive to O3 than the universally used O3-bioindicator, tobacco Bel W3, under the Egyptian environmental conditions used. These plant species, jute (Corchorus olitorius c.v. local), clover (Trifolium alexandrinum L. c.v. Masry), garden rocket (Eruca sativa c.v. local) and alfalfa (Medicago sativa L. c.v. local), ranked in order of decreasing sensitivity, exhibited typical O3 injury symptoms faster and at lower O3 concentrations than Bel W3. Three variables were tested in search of a reliable tool for the diagnosis and prediction of O3 response prior to the appearance of visible foliar symptoms: pigment degradation, stomatal conductance (gs) and net photosynthetic CO2 assimilation (Pnet). Pigment degradation was found to be unreliable in predicting species sensitivity to O3. Evidence supporting stomatal conductance involvement in O3 tolerance was found only in tolerant species. A good correlation was found between gs, restriction of O3 and CO2 influx into the mesophyll tissues, and Pnet. Changes in Pnet seemed to depend largely on fluctuations in gs

    The antinociceptive effect of methanolic extracts (200 and 400 mg kg(-1)) of eight Egyptian medicinal plants was studied using acetic acid-induced writhing and tail-flick test in mice. Oral administration of 400 mg kg(-1) methanolic extracts of Convolvulus fatmensis, Alhagi maurorum, Plantago major seeds, Conyza dioscaridis significantly (P Plantago major leaves and Mentha microphylla, in the large dose, showed a protection of 50.8-45.8%, which were significantly different as compared to control. The smaller dose of the tested plant extracts did not protect animals from painful acetic acid stimulation with the exception of Alhagi maurorum. In the tail-flick test, methanolic extracts of Mentha microphylla, Conyza dioscaridis, Alhagi maurorum, Plantago major leaves, Diplotaxis acris and Convolvulus fatmensis in a dose of 400 mg kg(-1) produced significant increase in the latency to response of tail to thermal stimulation. Mild or no effect was observed by the small dose with the exception of Diplotaxis acris that had significant antinociceptive effect at the dose of 200 mg kg(-1). The extracts of all tested plants in doses up to 2 g kg(-1) b.wt. did not cause any deaths or major signs of acute toxicity. Phytochemical screening indicated the presence of unsaturated sterols, triterpenes, tannins, flavonoids and carbohydrates and/or glycosides as major constituents. PMID:15507342

    Full Text Available Background Beta-thalassemia major (β-TM patients need blood transfusions, which result in iron deposition. To regulate chelation therapy, iron load has to be measured. With MRI, the amount of signal loss and T2* decay time shortening are used for iron quantification. Objectives The aim was to measure adrenal iron load with T2* relaxometry using MRI, and to compare it with liver and cardiac iron and serum ferritin, and to find out whether adrenal iron could be predicted from those parameters. Patients and Methods Between October 2014 and March 2015, MRI was performed in 21 patients with β-TM, recieving blood transfusions and chelation therapy. The control group (n = 11 included healthy volunteers with no known history of adrenal, hematologic, chronic disease, and blood transfusion. Results Among patients, there was no significant correlation between plasma ferritin and adrenal T2*. Significant difference was detected among T2* values of adrenals between the patient and control groups. There was no significant correlation between adrenal gland and liver T2* in β-TM patients, moderate correlation was detected between adrenal T2* and cardiac T2*. Conclusion Adrenal iron in β-TM can be reliably measured in 3 Tesla MRI. The results highlight the absence of correlation between adrenal iron deposition both with serum ferritin and hepatic iron.

    The objective is to summarize the pattern of Egyptian migration to Arab oil-producing countries (AOPC), to review some factors that are important determinants of labor movement based on theory, and to empirically model the migration rate to AOPC and to Saudi Arabia. Factors are differentiated as to their relative importance. Push factors are the low wages, high inflation rate, and high population density in Egypt; pull factors are higher wages. It is predicted that an increase in income from destination countries has a significant positive impact on the migration rate. An increase in population density stimulates migration. An increase in inflation acts to increase out-migration with a 2-year lag, which accommodates departure preparation. Egypt's experience with labor migration is described for the pre-oil boom, and the post-oil boom. Several estimates of labor migration are given. Government policy toward migration is positive. Theory postulates migration to be determined by differences in the availability of labor, labor rewards between destination and origin, and the cost of migration. In the empirical model, push factors are population density, the current inflation rate, and the ratio of income/capita in AOPC to Egypt. The results indicate that the ratio of income/capita had a strong pull impact and population density had a strong push impact. The inflation rate has a positive impact with a lag estimated at 2 years. Prior to the Camp David Accord, there was a significant decrease in the number of Egyptian migrants due to political tension. The findings support the classical theory of factor mobility. The consequences of migration on the Egyptian economy have been adverse. Future models should disaggregate data because chronic shortages exist in some parts of the labor market. Manpower needs assessment would be helpful for policy makers.

    1993-01-01

    A national conference was held September 7-8, 1992, by the Central Agency for Mobilization and Statistics to discuss the findings of the Egyptian Maternal and Child Health Survey. The infant mortality rate (IMR) declined from 116 deaths/1000 live births during 1971-75 to 56/1000 during 1986-89. Residence and mother's education had major effects upon IMR. The prevention and control of diarrheal illness could further reduce the rates of infant and child mortality. The survey emphasizes the importance of promoting the awareness of the need for immunization, especially among rural mothers, and stresses the importance of providing medical care during pregnancy and at delivery to the health of both children and mothers. Increasing educational opportunities have contributed to the decline in early marriage and the upward trend in age at first marriage. Compared to urban residents, a higher proportion of rural residents marry their first cousins, while dissolution of marriage is due to either death or divorce. There is an inverse relationship between level of education and completed and complete fertility rates. 63% of women stated their desire to have 2-3 children as the ideal family size, with rural upper Egyptian women tending to report the highest ideal number of children. Egyptian women prefer a combination of sons and daughters with a higher tendency for son preference. There is almost universal knowledge of contraception in Egypt, with the IUD and oral pills the methods used most often by Egyptian women. Approximately 61% of urban women and 38% of rural women were using contraception at the time of the survey. Reasons for future non-use of contraception were the desire to bear more children, fatalism, being infecund, husband's disapproval, and the fear of contraceptives' side effects. PMID:12179787

The revolutions of Arab Spring, including the Egyptian revolution, are considered one of the most important and most dangerous events in the XXI century after the terrorist attacks of 11 September 2001, not only in the Middle East but throughout the world because of their impact on peace and global security. The growth of the phenomenon of political Islam and the advent of Islamists into power in Egypt has represented one of the most remarkable features of this sudden revolution. No doubt that the issue of the relationship between Islam and the state's political system raises many confusing questions for many people. In this sense the importance of this study will directly identify the fact that the leadership of Islamists in Egypt is not the implementation of Islamic Sharia but their movements and ideology.

    Full Text Available Aims: Medicinal plants have recently received the attention of the antimicrobial activity of plants and their metabolites due to the challenge of growing incidences of drug-resistant pathogens. The aims of this study were to determine the antibacterial activities of plant extracts used as ethnomedicinal in Egypt. Methodology and Results: Investigations were carried out to assess the antibacterial efficiency of 11 plant extracts used as ethnopharmacological among Egyptian native people against infectious diseases. Crude methanol, ethanol,chloroform, hexane, acetone and aqueous extract of plants were tested for antibacterial activity in vitro against ten bacterial isolates using the disc diffusion method test. Discs were impregnated with 2 mg/mL of different solvent extracts. Among all the crude extracts, the methanol extract showed the highest activity than other extracts. P. harmala and S. officinalis exhibited highest antibacterial activity against gram positive and negative bacteria while the remainingplants extracts showed less activity. All the plant extracts showed no significant effect against the Bordetella bronchisepta ATCC 4617 except the extracts of M. fragrans and L. sativum. E. coli is the most sensitive microorganism tested, with the lowest MIC value (0.5 mg/mL in the presence of the plant extract of P. harmala and S. officinalis.Conclusion, significance and impact of study: Results obtained herein, may suggest that the ethnomedicinal Egyptian plants possess antimicrobial activity and therefore, they can be used in biotechnological fields as natural preservative ingredients in food and/or pharmaceutical industry.

    This article reviews evidence that contemporary Egyptian international labor migration to oil-rich Arab countries has followed a classic social process which starts with a homo economicus phase, advances into a goal reorientation phase, and ends with the establishment of diaspora communities in destination societies. The history of Egyptian migration, current estimates of migration, the role of Egyptians in selected Arab countries, and emergent processes all were found to support the predictions of the social process model. Particularly important support comes from the finding that all social classes participated in this migration. For 1982, the Ministry for Foreign Affairs, based on individual consulate figures, reported 2.9 million migrants in oil-rich countries. Conclusions suggest the likelihood that Egyptian migration processes will promote economic and perhaps social integration in the region. PMID:12281731

    2001-01-01

    To see Egypticism as merely a variety of neo-classicism sems too restrictive when one realizes the extent to which Western civilization has been inspired by Egypt. The interchangeability of terms covering that inspiration is confusing, so an attempt has been made to standardize them. The results...... are often contrary to what the ancients themselves would have understood or condoned. Practical considerations of form or a perenial sense of aesthetics, rather than Egyptian prototypes, may be behind much that looks Egyptian....

    Full Text Available Background The highly pathogenic H5N1 is a major avian pathogen that intensively affects the poultry industry in Egypt even in spite of the adoption of vaccination strategy. Antigenic drift is among the strategies the influenza virus uses to escape the immune system that might develop due to the pressure of extensive vaccination. H5N1 mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences such an eventuality will entail. Methods H5N1 was isolated from the pooled organ samples of four different affected flocks in specific pathogen free embryonated chicken eggs (SPF-ECE. A reverse transcriptase polymerase chain reaction (RT-PCR was performed to the haemagglutingin and neuraminidase. Sequencing of the full length haemagglutingin was performed. Sequence analyses of the isolated strains were performed and compared to all available H5N1 from Egyptian human and avian strains in the flu database. Changes in the different amino acid that may be related to virus virulence, receptor affinity and epitope configuration were assigned and matched with all available Egyptian strains in the flu database. Results One out of the four strains was found to be related to the B2 Egyptian lineage, 2 were related to A1 lineage and the 4th was related to A2 lineage. Comparing data obtained from the current study by other available Egyptian H5N1 sequences remarkably demonstrates that amino acid changes in the immune escape variants are remarkably restricted to a limited number of locations on the HA molecule during antigenic drift. Molecular diversity in the HA gene, in relevance to different epitopes, were not found to follow a regular trend, suggesting abrupt cumulative sequence mutations. However a number of amino acids were found to be subjected to high mutation pressure. Conclusion The current data provides a comprehensive view of HA gene evolution among H5N1 subtype viruses in

    Fabritius discovered the first variable star, Mira, in 1596. Holwarda determined the 11 months period of Mira in 1638. Montanari discovered the next variable star, Algol, in 1669. Its period, 2.867 days, was determined by Goodricke (178). Algol was associated with demon-like creatures, "Gorgon" in ancient Greek and "ghoul" in ancient Arab mythology. This indicates that its variability was discovered much before 1669 (Wilk 1996), but this mythological evidence is ambiguous (Davis 1975). For thousands of years, the Ancient Egyptian Scribes (AES) observed stars for timekeeping in a region, where there are nearly 300 clear nights a year. We discovered a significant periodicity of 2.850 days in their calendar for lucky and unlucky days dated to 1224 BC, "the Cairo Calendar". Several astrophysical and astronomical tests supported our conclusion that this was the period of Algol three millennia ago. The "ghoulish habits" of Algol could explain this 0.017 days period increase (Battersby 2012).

The questionnaire was supported with simplified information about the use of atomic energy and radiation for peaceful purpose. From the results, 62.43% of the total sample size accepted the radiation technology persons that were convinced with the advantage of using irradiated food reached 70.45% . As to keep on being applied of the technology 73.97% of the total sample size agreed persons said yes to irradiated food for consumption if it is made available in the market were 57.53%

  16. Radiation levels in ancient Egyptian mummies

    International Nuclear Information System (INIS)

    Radiation levels were studied in the mummies room and some galleries in the Egyptian museum as well as in the medical museum of the Faculty of Medicine, Cairo University. ''gamma'' and β radiation levels show almost background values in direct contrast to some mummies in the closed mummies room and inside the glass cases used for protection. Radon decay products in the room atmosphere and inside the glass cases enclosing some mummies show slightly higher levels than the background which were attributed to inefficient ventilation. After reasonable ventilation during the work these levels approached the normal values. High resolution γ-ray spectroscopy measurements for the aerosol samples on the filters have shown background values. The results indicated that the mummies do not contain any radioactivity content or any radioactive sources as was previously suggested. (Author)

  17. Spectral signature of Egyptian crude oils

    International Nuclear Information System (INIS)

    Crude petroleum oils are complex mixtures of diverse hydrocarbons, in widely varying compositions, that originate from a variety of geological sources. Fluorescence emission spectra have been measured for two types of Egyptian crude petroleum oil, its light and heavy products over a broad range of excitation and emission wavelengths. Both types of crude oil products are characterized by spectral signatures with a differing topography: the number of fluorescent peaks, their coordinates (λex, λem) on the plane of the three dimensions spectrum, and the shape of the bands formed by the contour line density, changeable in either direction. The refined light oil shows emission spectra at λmax between 350 and 500 nm according to the excitation wavelength. The refined heavy oil shows very broad unstructured emission spectra with λmax > 400 nm. As a group, they could certainly be distinguished from the light oil samples and most of the crude oil

  18. Examination of an Egyptian mummy - stereolithography applied

    International Nuclear Information System (INIS)

    This paper describes the techniques of three dimensional imaging and stereolithography based on serial CAT-scans applied to the examination of the skull of an Egyptian mummy. Both the three dimensional image and the polymeric cast of the mummy skull presented finer details. It was confirmed that the subject was a male, approximately 30 - 35 years old. Fracturing of the ethmoid bone, e=sequelae to the removal of the brain, was observed in both types of presentations. Apart from this and signs of parodontitis, no pathology was observed. Stereolithography is a most powerful, non-destructive approach to the study of mummies. It might solve some of the problems of reburials, and further be of value in forensic medicine and paleo-ontology. (authors)

    Full Text Available Problem statement: Associating any knowledge from ancient Egyptians to modern civilization and thinking was important and had its own value. The process of understanding knowledge related to ancient Egyptians is actually based on the nature of philosophical thought. Approach: In the discussion of ancient Egypt philosophy, it is important to look at it from the perspectives of the four branches of philosophy; metaphysics, epistemology, axiology and logic. Metaphysics has two elements, which are ontology and cosmology. Arguments in ontology explain why most activities of people from the ancient Egypt involved agriculture and how they perceived their lives in the midst of this activity, this includes the concept of human creator; treatment to man and woman; and Egyptians’ Gods and Goddesses. In addition, cosmology analyses the universe; everything inside and out of it, as well as what makes them stay and move. Results: Whereas, epistemology refers to how ancient Egyptians appreciated the existence of knowledge among them by considering the sources, types, categories and importance of particular knowledge that was gained in different ways. Besides, the aspects of axiology are also discussed here, especially in the ancient Egypt’s hieroglyphics. This writing discusses the level of aesthetical value posed by all these Egyptians, even at the time of about 3000 B.C. They could discuss to form pictographic as their written language. This activity lasted for thousands of years. Conclusion: Last but not the least, logic is another aspect that can be used in the discussion across metaphysics, epistemology and also axiology, for instance, the thinking of the philosophy behind Egyptians life. This writing relates the philosophy of ancient Egypt with the life of the modern world, not only in Egypt, but also in another part of the world, which exist from the impact of the philosophy of ancient Egypt. Modern views of Egyptians’ thinking are often vastly based

  2. The Egyptian legislation for safe transportation of radioactive materials

    International Nuclear Information System (INIS)

    According to the Egyptian legislation related the safe transport of radioactive materials, a licence is required for the transport, import and or export these materials. The licence is granted, upon a written application to NCNSRC-AEA. All the procedures and conditions for granting the NCNSRC-AEA licence to handle/ transport radioactive materials/wastes have been developed according to the international and Egyptian legislation. The procedures for transit of ships carrying radioactive materials in Suez Canal are also constructed. The NCNSRC-AEA experts are entitled to accept or to refuse the transit of ships carrying radioactive materials in the Suez Canal, in the Egyptian regional waters, in the sea harbours or in the exclusive economic zones of Egypt according to the national and international regulations.

    Oil fly and boiler ash samples were collected from the four major Egyptian power plants in order to determine their natural radioactivity. Secular equilibrium between (238)U and (232)Th and their decay products is significantly disturbed in oil ash samples. The (226)Ra/(238)U ratios were between 440 and 1993 with an average value of 801, indicating that the concentrations of daughters (226)Ra were very high compared to the parent (238)U in the oil ash samples. While, the average ratios for (210)Pb/(226)Ra in most samples were 1.19 ± 0.05, indicating a secular equilibrium in the (226)Ra-(210)Pb sub series. The natural radioactivity due to (238)U and (232)Th was found to be negligible. While the activity concentrations of (226)Ra ranged from 3205 to 12,320 Bq kg(-1) with an average value of 9284 Bq kg(-1), (210)Pb ranged from 5960 to 13,930 Bq kg(-1) with an average value of 11,513 Bq kg(-1). The results are compared with the reported data from other countries. The average value of radium equivalent activity was 9308 ± 2729 Bq kg(-1), while the external and internal hazard indexes were found to be 25 ± 7 and 50 ± 15, respectively. All the studied radiological parameters were higher than the recommended limit by the IAEA in all ash samples. PMID:27126872

    Full Text Available Background: Tuberculosis remains a major health problem in developing countries especially with the emergence of multidrug resistant strains. Mendelian Susceptibility to Mycobacterial Disease (MSMD is a rare disorder with impaired immunity against mycobacterial pathogens. Reported MSMD etiologies highlight the crucial role of the Interferon gamma /Interleukin 12 (IFN-g/ IL-12 axis and the phagocyte respiratory burst axis. Purpose: Screen patients with possible presentations for MSMD. Methods: Patients with disseminated BCG infection following vaccination, atypical mycobacterial infections or recurrent tuberculosis infections were recruited from the Primary Immune Deficiency Clinic at Cairo University Specialized Pediatric Hospital, Egypt and immune and genetic laboratory investigations were conducted at Human Genetic of Infectious Diseases laboratory in Necker Medical School, France from 2005-2009. IFN-g level in patient’s plasma as well as mutations in the eight previously identified MSMD-causing genes were explored. Results: Nine cases from eight (unrelated kindreds were evaluated in detail. We detected a high level of IFN-g in plasma in one patient. Through Sanger sequencing, a homozygous mutation in the IFNGR1 gene at position 485 corresponding to an amino acid change from serine to phenylalanine (S485F, was detected in this patient. Conclusion: We report the first identified cases of MSMD among Egyptian patients, including in particular a new IFNGR1 mutation underlying IFN-gR1 deficiency. The eight remaining patients need to be explored further. These findings have implications regarding the compulsory Bacillus Calmette Guerin vaccination policy in Egypt, especially given the high consanguinity rate.

    Neonatal jaundice (NNJ) is one of the most common neonatal disorders worldwide. It is still a main cause of avoidable brain damage, physical and mental impairment, and probable death in newborns.We aimed to assess perceptions, practices, and traditional beliefs among Egyptian mothers toward NNJ that may contribute to delayed presentation and inappropriate management of hyperbilirubinemia.This descriptive, cross-sectional study was conducted from January to May 2015. We interviewed 400 Egyptian mothers who gave birth in knowledge and attitude scores of Egyptian mothers in most domains with a mean of 6.6 and 20.6, respectively, although the majority of them were illiterate or had low educational attainment. In terms of knowledge, 52.3% of participants had adequate knowledge about NNJ in the aspects of awareness, risk factors, management, and complications. Almost all participants exhibited moderate (89.8%) and high levels (10%) of positive attitudes toward NNJ. Maternal sociodemographic factors influenced knowledge level, attitudes, and behaviors related to NNJ in Egypt. Working mothers and those residing in urban areas were significantly more knowledgeable (P = 0.023 and 0.021, respectively), and attained higher attitude scores (P knowledge and attitudes related to NNJ. However, cultural beliefs and traditional infant care practices still have an impact on mothers regardless of their educational level. PMID:27603393

    The bitter orange flower oil (or neroli) is an essential product, largely used in perfumery. Neroli is obtained by hydrodistillation or steam distillation, from the flowers of bitter orange (Citrus aurantium L.). Since a long time neroli production is limited and its cost on the market is considerably high. The annual production in Tunisia and Morocco is ca. 1500 Kg, representing more than 90% of the worldwide production. A small amount ofneroli is also produced in Egypt, Spain and Comorros (not exceeding 150 kg totally). Due to the high cost, the producers and the users have tried to obtain less expensive products, with odor characters close to that of neroli oil to be used as substitute and sometimes as adulterants of the genuine oil. In this study are investigated five samples of Egyptian neroli oils produced in 2008 and 2009, in the same industrial plant, declared genuine by the producer. For all the samples the composition was determined by GC/FID and by GC/MS-LRI; the samples were also analyzed by esGC to determine the enantiomeric distribution of twelve volatiles and by GC-C-IRMS for the determination of the delta13C(VPDB) values of some mono and sesquiterpene hydrocarbons, alcohols and esters. The analytical procedures allowed to quantitatively determining 86 components. In particular the variation of the composition seems to be dependent on the period of production. In fact, the amount of linalool decreases from March to April while linalyl acetate presents an opposite trend, increasing in the same period. The RSD determined for the delta13C(VPDB) are very small (max. 3.89%), ensuring the authenticity of all samples. The results are also discussed in function of the limits provided by the European Pharmacopoeia (EP) (2004), AFNOR (1995) and ISO (2002) regulations for genuine neroli oils. PMID:21834247

    Full Text Available Background and Aim: With the introduction of long term subcutaneous administration of Deferoxamine there has been a decline in the morbidity and mortality of transfusion-dependent beta thalassemia patients. But parenteral iron chelation therapy is still a burden and a major reason for unsatisfactory compliance and places an additional psychological burden on the patients. There are some factors contributing to low compliance in these patients. To evaluate compliance to Deferoxamine and barriers of non adherence and assessment the prevalence of depression and it’s association with compliance. Materials and Methods: 205 patients with major thalassemia in children medical center older than 6 years old were included. They were classified in 3 groups by compliance index (CI: No. of days of treatment per one month/No. of treatment days prescribed by physician. CI>75 % was considered good ,CI< 50-75%: moderate,CI<50%:weak and 3d group the patients without compliance. For assessment of depression: Beck Depression questionnaires were given to the patients older than 18 years old and Children Depression Inventories (CDI“kovacs” were given to the rest Results: Of 205 patients (110 females (54% and 95 males (46%, 13.3% were non compliant, 14% had poor compliance, 62.7% had good compliance. Females were more compliant than males (P=0.034. Compliance improved in older age groups meaningfully (P=0.037. There was negative association between compliance and serum ferritin level (P=0.02. 22% of children and 12% of Adults had severe depression according to the questionnaires. There was no association between compliance and depression. The most prevalent problem rgarding Desferal injection was local reactions in injection site (83%. Conclusion: As oral chelation therapies are not used routinely, more investigations regarding the noncompliance must be considered; and this method of chelation therapy must be encouraged. Compliance is a multifactorial problem

    Full Text Available Background: Deep vein thrombosis (DVT is a blood clot in a major vein, usually in the legs and/or pelvis. If part of the thrombus breaks off, it becomes an embolism, which can travel through the heart and block the arteries to the lungs. Factor V Leiden (FVL is a common genetic risk factor for hereditary hypercoagulability disorder in several populations. The present study investigates the association of FVL mutation with DVT among Egyptian cases. Patients & methods: The study included 44 cases (16 males and 28 females with an age range of 20 to 80 years in addition to 211 healthy unrelated controls of matched age and sex. A multiplex allele-specific PCR amplification was conducted for assignment of FVL gene mutation (G1691A. Results: Cases having the mutant allele A (AA and AG genotypes were significantly higher than controls (38.6% vs. 18.5%; P < 0.05, OR= 2.78 and CI 95%, 1.380­5.589. Conclusion: These results concluded that FVL mutation has a high frequency and positive association with the occurrence of deep vein thrombosis among Egyptian cases

    Full Text Available Metaphor is persuasive in having cognitive, emotional and aesthetic effect. It has been argued that any visual representation can be considered a metaphor if it represents a metaphoric thought. Chartris-Black’s Critical Metaphor Analysis and Forceville’s model of pictorial metaphor are both used to analyze the data under investigation. Chateris-Black’s Critical Metaphor Analysis is used based on the idea that the use of metaphors helps in conveying the underlying ideologies of the writers. Moreover, Forceville’s model of pictorial metaphor aims at investigating various types of pictorial metaphor in different genres. The political cartoons investigated in this study are drawn from three independent newspapers: Al Dastour, Al Masry Al Youm and Al Youm AL Sabea during the 25th of January 2011 Egyptian Revolution. This study aims at exploring how metaphors are expressed in the visual mode, more specifically in newspapers cartoons, tracing the use of pictorial metaphor in selected independent newspapers cartoons during the eighteen days of the 25th of January 2011 Egyptian revolution, and finally, identifying the cartoonists’ underlying ideological motivations and their attitudes to the revolution, which ultimately direct the audience’s ideology. The results of this study suggest that Chateris-Black’s Critical Metaphor Analysis can be applied not only on the textual level, but also on the semiotic and pictorial ones. In addition, metaphors are frequently used in political cartoons to evoke strong emotive effect and reinforce ideologies to achieve persuasion.

    AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

  1. On improvement in ejection fraction with iron chelation in thalassemia major and the risk of future heart failure

    Full Text Available Abstract Background Trials of iron chelator regimens have increased the treatment options for cardiac siderosis in beta-thalassemia major (TM patients. Treatment effects with improved left ventricular (LV ejection fraction (EF have been observed in patients without overt heart failure, but it is unclear whether these changes are clinically meaningful. Methods This retrospective study of a UK database of TM patients modelled the change in EF between serial scans measured by cardiovascular magnetic resonance (CMR to the relative risk (RR of future development of heart failure over 1 year. Patients were divided into 2 strata by baseline LVEF of 56-62% (below normal for TM and 63-70% (lower half of the normal range for TM. Results A total of 315 patients with 754 CMR scans were analyzed. A 1% absolute increase in EF from baseline was associated with a statistically significant reduction in the risk of future development of heart failure for both the lower EF stratum (EF 56-62%, RR 0.818, p Conclusion These data show that during treatment with iron chelators for cardiac siderosis, small increases in LVEF in TM patients are associated with a significantly reduced risk of the development of heart failure. Thus the iron chelator induced improvements in LVEF of 2.6% to 3.1% that have been observed in randomized controlled trials, are associated with risk reductions of 25.5% to 46.4% for the development of heart failure over 12 months, which is clinically meaningful. In cardiac iron overload, heart mitochondrial dysfunction and its relief by iron chelation may underlie the changes in LV function.

    A novel DNA virus designated TT virus (TTV) has been reported to be involved in the development of posttransfusion non-A-C hepatitis. We evaluated the frequency and natural course of TTV infection in a cohort of transfusion-dependent thalassemic patients in a 3-year follow-up study. Ninety-three serum hepatitis C virus (HCV) antibody-negative patients (median age of 8 years; range, 0 to 25) from eight centers were studied. Of them, 34 (37%) had an abnormal alanine-aminotransferase (ALT) baseline pattern, and the other 12 (13%) showed ALT flare-ups during the follow-up. TTV DNA in patient sera collected at the time of enrollment and at the end of follow-up was determined by polymerase chain reaction (PCR). In parallel, serum samples from 100 healthy blood donors were also tested. At baseline, 87 patient sera (93.5%) tested positive for the TTV DNA. Of these TTV DNA-positive patients, 84 (96.5%) remained viremic at the end of the study period. Of the 6 TTV DNA-negative patients, 3 acquired TTV infection during follow-up. However, no definite relation was observed between the results of TTV DNA determination and ALT patterns. TTV viremia was also detectable in 22% of blood donors. In conclusion, TTV infection is frequent and persistent among Italian transfusion-dependent patients. The high rate of viremia observed in healthy donors indicates that the parenteral route is not the only mode of TTV spread.

    Full Text Available Previous studies have demonstrated impaired ventricular repolarization in patients with β-TM. However, the effect of iron overload with cardiac T2* magnetic resonance imaging (MRI on cardiac repolarization remains unclear yet. We aimed to examine relationship between repolarization parameters and iron loading using cardiac T2* MRI in asymptomatic β-TM patients. Twenty-two β-TM patients and 22 age- and gender-matched healthy controls were enrolled to the study. From the 12-lead surface electrocardiography, regional and transmyocardial repolarization parameters were evaluated manually by two experienced cardiologists. All patients were also undergone MRI for cardiac T2* evaluation. Cardiac T2* score <20 msec was considered as iron overload status. Of the QT parameters, QT duration, corrected QT interval, and QT peak duration were significantly longer in the β-TM group compared to the healthy controls. Tp−Te and Tp−Te dispersions were also significantly prolonged in β-TM group compared to healthy controls. (Tp-Te/QT was similar between groups. There was no correlation between repolarization parameters and cardiac T2* MRI values. In conclusion, although repolarization parameters were prolonged in asymptomatic β-TM patients compared with control, we could not find any relation between ECG findings and cardiac iron load.

    Egyptian blue has been identified in a painting from 1524 by the Italian artist Ortolano Ferrarese (Giovanni Battista Benvenuto). Egyptian blue is the oldest known synthetic pigment, invented by the Egyptians in the fourth dynasty (2613-2494 BC) of the Old Kingdom and extensively used throughout Antiquity. From about 1000 A.D., it disappeared from the historical record and was only reinvented in the late nineteenth and early twentieth century. The discovery of Egyptian blue in Ortolano Ferrarese's painting from 1524 shows that Egyptian blue was in fact available in the period from which it is normally considered not to exist. The identification of Egyptian blue is based on optical microscopy supported by energy-dispersive spectroscopy and visual light photon-induced spectroscopy, and finally confirmed by Raman microspectroscopy.

    Full Text Available Background: Healthful eating is essential for development and well-being. Some dietary patterns are associated with 4 of the 10 leading causes of death (coronary heart disease, certain types of cancer, stroke, and type 2 diabetes. Major improvements in the health of the public can, therefore, be made by improving people's dietary patterns. The U.S. department of Agriculture has developed an index, called the Healthy Eating Index (HEI that was updated in the year 2002. It is based on different aspects of a healthful diet; the Index is designed to provide a measure of overall dietary quality, and the compliance with specific Dietary Guidelines recommendations. The aim of our study is to use the healthy eating index to assess the diet quality of a representative sample of the Egyptian children and adolescents and to examine the association between body mass index and caloric intake of the studied sample. Materials & Methods: This study is a part of National Egyptian survey, Diet, Nutrition and Prevention of Chronic Non-communicable Diseases. The Healthy Eating Index was applied with slight modifications to measure how well the studied Egyptian students' diet conforms to recommended healthy eating pattern. The data were based on representative sample (2145 of children and adolescents (10 -18 years in 7 governorates from. One day of dietary intake data (24 hours recall was collected, during an in-person interview. The Healthy Eating Index measures how well the studied children and adolescents' diets conform to the American Dietary Guidelines recommendations and the Food Guide Pyramid applied in our country. Ten dietary components have been identified and the overall Index has a total possible score ranging from zero to 100. Results: Our results showed that the average Healthy Eating Index score was 59.1 out of a possible 100 and it ranged from 20 to 86, Only 0.5 percent of the students had Healthy Eating scores above 80; while 16.9 percent of them

    2013-08-01

    Full Text Available This paper deals with questions of the politics of location in knowledge and norm production within the context of Egyptian feminist activism for abandoning female genital cutting practices. It seeks to determine underlying schemes of international campaigning discourse and analyzes how these predicate and complicate Egyptian postcolonial activism. It draws on a broad literature study in addition to fieldwork in Cairo consisting of in-depth interviews with activists and policy makers. My focus is on the national Task Force against FGM from 1994 until 1999 and its subsequent cooptation by the National Council of Childhood and Motherhood. I argue through the concept of catachresis that location matters in setting the terms of anti-FGC discourse and its relation to religion.

    2013-01-01

    The study investigated the relationship between psychosocial problems and personality disorders among a sample of 817 Egyptian adolescents (408 males and 409 females). Using 15 subscales from the Adolescent Psychopathology Scale (APS-long form) we assessed prevalence rates of a number of internalizing and externalizing psychosocial disorders. Additionally, we investigated whether there are gender differences in psychopathology among Egyptian adolescents and to what extent can psychosocial problems predict specific personality disorders. Stepwise multiple regression analyses showed that the participants experienced higher levels of PD, AV, and BD. Gender differences were found in certain personality disorders as well as in externalizing and internalizing psychosocial problems. A number of externalizing and internalizing psychosocial problems were highly predictive of specific personality disorders.

    Although ancient Greek and Roman medicine is generally considered the origin of European medicine, there is evidence in ancient Egyptian texts suggesting a precursor role of ancient Egyptian medicine in this regard. What did Greek and Roman physicians learn from their Egyptian counterparts? Of the medical papyri discovered to date, the largest and most significant - the Ebers papyrus and the Smith papyrus - originate from the beginning of the New Kingdom, however, they were - at least in part - already written during the Old Kingdom. Considering the times, the spectrum of diseases treated as well as the range of conservative and surgical treatment methods was truly astounding. Taking a medical history, performing a thorough manual examination, and assessing clinical findings constituted key components in establishing a diagnosis. Apart from hygienic aspects, skin and hair disorders, the treatment of acute and chronic wounds and injuries as well as cosmetic procedures took on an important role. Even back then, physicians sought to assess inflammatory processes with respect to their cardinal features, implement graded wound therapy, and treat diseases with allopathic drugs. The 'channel theory' prevalent at that time, in which the unimpeded flow of bodily fluids was considered a fundamental prerequisite for health, may likely be regarded as precursor of ancient Greek humoral pathology. The latter became the basis for the subsequently established theory of the four humors, and was thus essential for the entire field of medieval medicine. PMID:27027749

    Full Text Available Literatures concerning the history of West African peoples published from 1900 to 1970 debate�the possible migrations of the Egyptians into West Africa. Writers like Samuel Johnson and�Lucas Olumide believe that the ancient Egyptians penetrated through ancient Nigeria but Leo�Frobenius and Geoffrey Parrinder frowned at this opinion. Using the works of these early�20th century writers of West African history together with a Yoruba legend which teaches�about the origin of their earliest ancestor(s, this researcher investigates the theories that the�ancient Egyptians had contact with the ancient Nigerians and particularly with the Yorubas.Intradisciplinary and/or interdisciplinary implications: There is an existing ideology�amongst the Yorubas and other writers of Yoruba history that the original ancestors of�the Yorubas originated in ancient Egypt hence there was migration between Egypt and�Yorubaland. This researcher contends that even if there was migration between Egypt and�Nigeria, such migration did not take place during the predynastic and dynastic period as�speculated by some scholars.

    Lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials. Chemical analysis of cosmetics samples found in Egyptians tombs and the reconstitution of ancient recipes as reported by Greco-Roman authors have shown that two non-natural lead chlorides (laurionite Pb(OH)Cl and phosgenite Pb(2)Cl(2)CO(3)) were purposely synthesized and were used as fine powders in makeup and eye lotions. According to ancient Egyptian manuscripts, these were essential remedies for treating eye illness and skin ailments. This conclusion seems amazing because today we focus only on the well-recognized toxicity of lead salts. Here, using ultramicroelectrodes, we obtain new insights into the biochemical interactions between lead(II) ions and cells, which support the ancient medical use of sparingly soluble lead compounds. Submicromolar concentrations of Pb(2+) ions are shown to be sufficient for eliciting specific oxidative stress responses of keratinocytes. These consist essentially of an overproduction of nitrogen monoxide (NO degrees ). Owing to the biological role of NO degrees in stimulating nonspecific immunological defenses, one may argue that these lead compounds were deliberately manufactured and used in ancient Egyptian formulations to prevent and treat eye illnesses by promoting the action of immune cells.

  19. The Traditional Egyptian Antecedents of Graeco-Roman Post-Mortem Ascent

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Despite the greater antiquity of Egyptian civilisation, when we refer to Egyptian and Graeco-Roman cultures, we are generally referring to cultures that were contiguous, and the profound impact that Egyptian ideas had upon the Graeco-Roman world cannot be denied. In key respects, Egyptian views of the afterlife foreshadowed Graeco-Roman, Jewish, and early Christian conceptions, particularly in terms of the motif of post-mortem ascent. Although the channels of transmission have been lost in antiquity, the motif may still be sketched clearly enough in both cultures to suggest that Egypt was an important source for its expression. After some methodological considerations, this essay will trace the motif of ascent as it was manifested in Graeco-Roman culture, and then analyze the nature of the ancient Egyptian evidence in order to suggest the existence of key elements of this same motif from the earliest times in ancient Egypt.

  2. Tolerance, quality and storability of gamma-irradiated Egyptian rice

    International Nuclear Information System (INIS)

    The effect of gamma irradiation on some organoleptic and physico-chemical properties and the storability of Egyptian rice was investigated. Radiation up to 50krad was chosen as an adequate dose causing non-significant changes in eating and cooking qualities. The effect of irradiation on degradation of starch and protein molecules is demonstrated on the basis of studies on the viscosity and solubility of rice paste. Irradiation at relatively low dose levels up to 50krad did not affect the chemical and nutritional qualities of rice regarding amino acids and B vitamins. It was also found that irradiation maintains better storability of rice under ambient temperature. (author)

    The Egyptian weasel (Mustela subpalmata) is a small mustelid with a distribution restricted to the lower Nile Valley and the Nile Delta. Traditionally considered a subspecies of the least weasel (M. nivalis), it is currently recognized as a separate species based on morphology. Here we present the first genetic assessment of the taxonomic status of the Egyptian weasel by comparing mitochondrial DNA (Cytochrome b gene and control region) sequences to those of least weasels from the western Palearctic, with a focus on the Mediterranean region. Our results provide no evidence to support the view that the Egyptian weasel is genetically distinct from the least weasel, as we found that, for both Cytochrome b and control region, haplotypes were shared between the two taxa. Specifically, the Cytochrome b and control region haplotypes detected in the Egyptian weasel were also present in M. nivalis from Turkey and Malta, two populations genetically analysed here for the first time. Our results suggest that the Egyptian weasel is distinct from the least weasel populations currently living in the Maghreb, which were inferred to be the result of an earlier colonization of North Africa, but the genetic data alone do not allow us to determine whether the Egyptian weasel is native or introduced. Nevertheless, the observed genetic patterns, together with the weasel fossil record in Israel and the unique commensal lifestyle of the Egyptian weasel, are consistent with the hypothesis that the Egyptian population is a relict of past range expansion from the Levant into Egypt. We suggest that the large size and characteristic sexual dimorphism of the Egyptian weasel are likely to represent ecotypic variation, but genomic studies are required to clarify the extent of its functional genetic divergence.

    By performing regular blood transfusion and iron chelation therapy, most patients with beta thalassemia major (BTM) now survive beyond the third decade of life. Liver disease is becoming an important cause of morbidity and mortality in these patients. Chronic hepatitis and/or severe iron overload are both important causes of liver pathology. Iron chelation with desferrioxamine (DFO) reduces excessive body iron, but its efficacy is limited by poor compliance and dose related toxicity. The recent use of Deferasirox ( DFX ), an oral single dose therapy, has improved the compliance to chelation. Aims To study the long-term liver functions in BMT patients, seronegative for liver infections before versus after DFX treatment in relation to ferritin level. Methods Only BTM patients with hepatitis negative screening (checked every year) and on treatment with DFO for at least five years and with DFX for four years were enrolled. Liver function tests including serum bilirubin, alanine transferase (ALT), aspartate transferase (AST), albumin, insulin-like growth factor – I (IGF-I) and serum ferritin concentrations were followed every six months in 40 patients with BTM. Results DFX treatment (20 mg/kg/day) significantly decreased serum ferritin level in patients with BTM; this was associated with a significant decrease in serum ALT, AST, ALP and increase in IGF-I concentrations. Albumin concentrations did not change after DFX treatment. ALT and AST levels were correlated significantly with serum ferritin concentrations ( r = 0.45 and 0.33 respectively, p < 0.05). IGF-I concentrations were correlated significantly with serum ALT (r= 0.26, p = 0.05) but not with AST, ALP, bilirubin or albumin levels. The negative correlation between serum ferritin concentrations and ALT suggests that the impairment of hepatic function negatively affect IGF-I synthesis in these patients due to iron toxicity, even in the absence of hepatitis. Conclusions Some impairment of liver function can occur

    Selected commercial and/or local vineyards and nurseries in three different governorates of Egypt (Alexandria, El-Beheira and El-Menofia) were surveyed for symptoms indicative of infection by grapevine viruses. Leaf samples from red-fruited and white-fruited Vitis vinefera were tested for grapevine leafroll associated viruses (GLRaV-1, GLRaV-2, and GLRaV-3), grapevine viruses A and B (GVA, GVB), grapevine rupestris stem pitting virus (GRSPaV), grapevine fanleaf virus (GFLV), and grapevine fleck virus (GFKV) from early April to late October 2010. Incidence of these viruses was assessed by RT-PCR in 60 different samples. Selected amplicons were sequenced. While GVA was the most wide spread (30%), GLRaV-1, GVB, GFLV, and GFKV were not detected during the survey. However, GVA, GLRaV-2, GLRaV-3, and GRSPaV were detected in the form of single infection or in mixed infections of 2 to 4 viruses. Phylogenetic analysis was performed on all Egyptian isolates of GLRaV-2 (4), GLRaV-3 (7), GVA (3), and GRSPaV (6). GRSPaV was detected for the first time in Egypt. Phylogenetic analysis provided insights into the evolutionary relationship between the reported Egyptian isolates and other previously reported isolates. PMID:24957718

  9. X-ray analysis of pigments on ancient Egyptian monuments

    International Nuclear Information System (INIS)

    Ancient pigments were analyzed using PIXE and XRD methods in the laboratory, which were painted on ancient Egyptian monuments. On the other hand, those on monuments remaining with entire shape were investigated using the hand-held type of an XRF spectrometer and an X-ray diffractometer in the field. For the laboratory experiment, several wall fragments of the Malqata palace in ancient Egypt (18th Dynasty, ca. 1390 B.C.) were investigated. In the field experiment, the block of Ramesses II (19th Dynasty, ca. 1270 B.C.), the Wooden Coffin of Neb-sny (18th Dynasty, ca. 1400 B.C.), the Funerary Stele of Amenemhat (11th Dynasty, ca. 2000 B.C.), and the painted walls of the Tomb of Userhat (18th Dynasty, ca. 1400 B.C.) were investigated. From white and blue colored parts, huntite and Egyptian blue were found, respectively, which are a very rare mineral and an artificial pigment prepared only in ancient Egypt, respectively. (author)

  10. Environmental education in an Egyptian university: The role of teacher educators

    Science.gov (United States)

    Goueli, Solafa

    Drawing on a holistic critical paradigm of ecological sustainability, this study examined the role of teacher educators in environmental education in the Faculty of Education of one Egyptian university. The study sought to critically and collaboratively explore with a sample of six teacher educators their answers, perceptions and perspectives in relation to their knowledge and understanding of environmental problems in local/global contexts and their meanings of curriculum and pedagogical practices for fostering environmental education in their teacher education programs. The participants generally demonstrated a considerable amount of knowledge of the environmental realities and problems facing Egypt encompassing air, water and solid waste sectors. Their views concurred with national and official studies identifying these issues as the most pressing environmental problems in the country. The exploration of the institutional, social and cultural causes and developmental and/or global causes of environmental problems in Egypt led us to articulate different themes relating environmental crisis in Egypt to different issues. These issues included poverty, education, religion and development. One of the major findings of the study was the participants' view that development was the major contributor to the environmental crisis in Egypt. They all stressed that, in its pursuit of economic growth, the government did not pay due attention to the environmental costs. Sharing perspectives from a critical paradigm of ecological sustainability, the participants felt that the government needed to clearly address the economic and ecological dimensions of development. In addition, a few participants affirmed that development is the thread that ties all the different factors together bringing into the conversations other dimensions of development like the social, values, and political dimensions. Addressing the future dimension of development, all of them expressed the need for a

    Jock M. Agai

    2013-07-01

    Full Text Available There are many cultural practices that connect ancient Egyptians to the Yorubas and the new interpretation of the Oduduwa legend suggests that the Yorubas have originated or are influenced mainly by the Egyptians. The attestation of Egypt as the main influencer of the Yoruba culture made Egypt significant in the study of the history of the Yoruba people. Some writers are beginning to think that the ancient Egyptians were responsible for introducing and spreading many cultures amongst the Yorubas. As more Yorubas are tracing their origins and the origins of their culture to ancient Egypt, this research investigates whether the Egyptians were the originators and the main spreaders of the afterlife culture in Yorubaland.

    2001-10-01

    Full Text Available The present investigation deals with the bleaching of vegetable oils using activated clays collected from some deposits in Egypt as compared to Tonsil FF currently used by local oil industry. The comparison was made; not only on the basis of the decolourising power of the earth, but also on the basis of its effects on the oil acidity, formation of the oil peroxides and the decomposition rate of the formed peroxides to aldehydes and ketones during the bleaching process. The activation of the collected earth samples was made using 4N HCl, 6N HCl and 30 % H2SO4. The bleaching tests of the activated samples were performed using the major four oil types processed in Egypt being cottonseed, sunflower, soybean and palm oils. In addition to the laboratory-evaluation tests, the performance of the activated samples, which showed promise on the lab-scale have been also tested on an industrial scale. The industrial application has proved that the activated local earth's can be successfully used as bleaching earth of local oils. Thus it can be used as a substitute of the varieties currently imported and used by the local oil sector.La presente investigación trata de la decoloración de aceites vegetales usando tierras activadas obtenidas de yacimientos egipcios, comparándola con el Tonsil FF usado normalmente en la industria oleícola local. La comparación se realizó, no sólo sobre la base del poder decolorante de la tierra, sino también sobre la base de sus efectos en la acidez del aceite, la formación de peróxidos y la velocidad de descomposición de los peróxidos formados en aldehidos y cetonas durante el proceso de decoloración. La activación de las muestras de tierras recogidas se hizo utilizando ClH 4N, ClH 6N y H2SO4 30 %. Los tests de decoloración de las muestras activadas se llevaron a cabo usando los cuatro tipos mayoritarios de aceites procesados en Egipto: aceite de semilla de algodón, de girasol, de soja y de palma.

    2006-02-01

    Three questionnaires that measure parenting style, adolescent-family connectedness, and mental health were administered to 351 Egyptian adolescents. Results show that in rural communities the authoritarian style is more predominant in the parenting of male adolescents, while the authoritative style is more predominant in the parenting of female adolescents. In urban communities, on the other hand, the authoritarian style was more predominant in the parenting of female adolescents. The connectedness of all female adolescents with their family was stronger than that of male adolescents. The connectedness of girls was found to be more emotional and financial in villages and to be more functional in town. Female adolescents reported a higher frequency of psychological disorders. Mental health was associated with authoritative parenting, but not with authoritarian parenting. It seems that authoritarian parenting within an authoritarian culture is not as harmful as within a liberal culture.

  5. Dose Assessment of Natural Radioactivity in Ancient Egyptian Monuments

    International Nuclear Information System (INIS)

    Within an environmental radiation investigation of the ancient Egyptian monuments sites, 151 environmental samples were analyzed using γ-ray spectrometers based on HPGe detectors. The results show that the activity concentration values of the naturally occurring radionuclides; 238U (22'6Ra), 232Th, and 40K respectively, are within the world average ranges.Two models for calculation of absorbed dose rate due to gamma emission from radionuclides in the studied soil, limestone and adobe samples were evaluated. The first model was established based on constant value of sample density. The second model takes the density variation into consideration. Two sets of conversion factors were evaluated. A comparison between the results of calculation of the absorbed dose of the studied samples based on the model adopted by UNSCEAR and on our two models was carried out and discussed. (authors)

  6. Synchrotron radiation analysis on ancient Egyptian vitreous materials

    International Nuclear Information System (INIS)

    Ancient Egyptian vitreous materials, namely faience and glass, share the same elemental composition. But they appear to have originated separately. Faience objects appear as early as the Predynastic period, and glass was introduced from Mesopotamia during the New Kingdom. These faience and glass objects were not of daily use, rather they were regarded as religious symbols or luxury status goods. Most of the products were coloured blue, but we see an increased use of other colours during the New Kingdom (c.1550-1069BC). This tendency corresponds to the period of both territorial and political expansion of Egypt. A non-destructive SR-XRF experiment at SPring-8 was conducted last winter, aiming to determine the regional trait of elemental composition by examining the pattern and ratio of rare earth elements. As a result, we could observe some distinctive rare earth elements that may indicate regional variation. (author)

  7. LAMQS analysis applied to ancient Egyptian bronze coins

    International Nuclear Information System (INIS)

    Some Egyptian bronze coins, dated VI-VII sec A.D. are analyzed through different physical techniques in order to compare their composition and morphology and to identify their origin and the type of manufacture. The investigations have been performed by using micro-invasive analysis, such as Laser Ablation and Mass Quadrupole Spectrometry (LAMQS), X-ray Fluorescence (XRF), Laser Induced Breakdown Spectroscopy (LIBS), Electronic (SEM) and Optical Microscopy, Surface Profile Analysis (SPA) and density measurements. Results indicate that the coins have a similar bulk composition but significant differences have been evidenced due to different constituents of the patina, bulk alloy composition, isotopic ratios, density and surface morphology. The results are in agreement with the archaeological expectations, indicating that the coins have been produced in two different Egypt sites: Alexandria and Antinoupolis. A group of fake coins produced in Alexandria in the same historical period is also identified.

  8. Fallout Radioactivity in Some Egyptian Lakes Bottom Sediments

    International Nuclear Information System (INIS)

    As a part of the Egyptian environmental radioactivity monitoring program, the fallout radioactivity levels in Qarun, Bardawill and Ed ku lakes bottom sediments have been measured. The specific activities of 137Cs were measured using gamma ray spectrometer based on Hyper pure germanium detector. The specific activities of plutonium isotopes(238Pu, 239+240Pu and 241Pu) were measured using alpha spectrometry based on surface battier detectors and liquid scintillation spectrometry after radiochemical separation. The activity ratios 239+240Pu/137Cs, 239+240Pu/241Pu, and 238Pu/ 239+240Pu were calculated. The results seemed to confirm that fallout radioactivity is mainly due to nuclear weapons testing fallout

    Full Text Available In recent years, social media has become very significant for social networking. In the past, itsmain use was personal, but nowadays, its becoming part of all facets of our lives, social andpolitical. In the first quarter of 2011, the Middle East has witnessed many popular uprisings thathave yet to reach an end. While these uprisings have often been termed “FacebookRevolutions” or “Twitter Revolutions”, there are many ambiguities as to the extent to whichsocial media affected these movements. In this paper we discuss the role of social media andits impact on the 2011 Egyptian revolution. Though the reasons for the uprising were manifold,we will focus on how social media facilitated and accelerated the movement.

    Full Text Available Grain samples of 14 Egyptian wheat cultivars were tested for seed-borne fungi. The deep freezing method was used. Five seed-borne fungi viz., Aspergillus flavus, A. niger, Curvularia lunata, Fusarium moniliforme and Penicillium chrysogenum were isolated from the wheat cultivars viz., Bani Suef 4, Bani Suef 5, Gemmiza 7, Gemmiza 9, Gemmiza 10, Giza 168, Misr 1, Misr 2, Sakha 93, Sakha 94, Shandaweel 1, Sids 1, Sids 2 and Sids 3. A. flavus, A. niger and F. moniliforme were the most prevalent fungal species. Their incidence ranged from 21.0-53.5%, 16.0-37.5%, and 12.0-31.0%, respectively. The antifungal potential of water extracts from aerial parts of five wild medicinal plants (Asclepias sinaica, Farsetia aegyptia, Hypericum sinaicum, Phagnalon sinaicum, and Salvia aegyptiaca were collected from the Sinai Peninsula, Egypt. The antifungal potential of water extracts from the aerial parts of these five plants were tested in the laboratory against the dominant fungi isolated from the wheat cultivars. All the aqueous plant extracts significantly (p ≤ 0.05 reduced the incidence of the tested seed-borne fungi. But the extract of Asclepias sinaica exhibited the most antifungal activity on tested fungi at all concentrations used when compared with other plant extracts. Maximum infested grain germination was observed in Giza 168 and minimum in Bani Suef 5. Treating grains with plant extract of A. sinaica (10% enhanced the percentage of grain germination of all cultivars in both laboratory and pot experiments. Maximum root and shoot length of seedlings was recorded in Bani Suef 4 during fungal infestation or treatment by plant extract. For one hour before sowing or storage, the aqueous extract of A. sinaica can be used to treat wheat grains, to reduce the fungal incidence. Aqueous extracts of the aerial parts of selected medicinal plants, particularly A. sinaica, are promising for protecting Egyptian wheat grain cultivars against major seed-borne fungi

    Breast cancer is the most common cancer among Egyptian women, accounting for 37.6% of female tumors, and is often diagnosed at later stages. The objective of this study was to investigate breast cancer patient navigation through the health care system in the Nile Delta. Interviews were conducted with 163 newly diagnosed breast cancer patients at the Tanta Cancer Center (TCC), the major cancer center of the region. Patients described their medical care pathway from the initial symptom experienced until their arrival at TCC. Patients whose initial contact was with a general surgeon (OR: 7.6, 95% CI: 2.1, 27.6), primary care provider (OR: 12.2, 95% CI: 2.9, 51.0), or gynecologist (OR: 8.6, 95% CI: 1.4, 53.4) were significantly more likely to experience a delay in reaching the TCC as compared to those visiting a surgical oncologist. Overcoming health care system and patient navigation barriers in developing countries may reduce the time for breast cancer patients to reach a cancer center for early management. PMID:21807518

  14. Relevance of medieval, Egyptian and American dates to the study of climatic and radiocarbon variability

    International Nuclear Information System (INIS)

    Basic radiocarbon dating and dendrochronology have been combined to yield calibrated dates that are more accurate than conventional radiocarbon dates. This has been shown to be true for medieval and Egyptian dynastic dating. Because radiocarbon is a cosmogenically produced radioisotope, heliomagnetic and geomagnetic fields play a major role in its synthesis in the Earth's upper atmosphere. Inasmuch as a calibrated radiocarbon record exists for nearly 10 000 years, we now seem to possess in the short-time variations of the production rate a history of solar activity expressed via heliomagnetic fields carried by the solar wind. In turn, solar activity has a controlling effect on climate on Earth within modifications provided by the complex interactions of the atmosphere-Earth-ocean system. Both radiocarbon measurements and other empirical research methods agree on variations of climate during historically more recent periods on Earth. This leads to the suggestion that the radiocarbon calibration curve may be also a significant indicator or tracer for climatic changes for the Holocene or the Neolithic-Mesolithic. (author)

    2016-05-01

    Full Text Available This is a longitudinal study of the identity process through times of dramatic social change. Using a narrative psychological approach this research follows the life stories of five Egyptian bloggers as they write their stories on online blogs over the course of the three years following the 2011 revolution, at which time Egypt has witnessed major social and political changes. The aim is to understand the identity process of individuals as they develop and adapt through changing social contexts and how they create alternative social relations as they engage in prefigurative politics. The findings shed light on how ruptures trigger a process of reflexivity, adaptive learning, and sense-making that facilitates coping and the reconstruction of a positive identity after ruptures. It also suggests that the narration of the experience of rupture through storytelling creates a heightened sense of agency in individuals’ ability to create new meanings of their world in spite of the socio-cultural and political constraints. This study presents narratives as an informing methodological resource that connects identity process with social representations and emphasizes the value of storytelling as an integral part of the adaptation process.

  17. Effect of irradiation and storage on biogenic amine contents in ripened Egyptian smoked cooked sausage

    International Nuclear Information System (INIS)

    The effects of γ-irradiation upon the biogenic amine inventory in Egyptian smoked cooked sausages were investigated for the first time during storage for up to 90 days at 4 ° C. Typical contents of biogenic amines in non-irradiated sausages ranged between 125.50 and 596.18 mg/kgDW; irradiation with 4 and 6 kGy decreased said total contents to 105.20-94.82 and 104.98-26.44 mg/kgDW respectively, by the end of storage. Putrescine and cadaverine were the major amines in non-irradiated samples - where it accounted for 33% and 29% respectively, of the total by 90 days; however, tyramine dominated in irradiated samples with 2, 4 and 6 kGy, where it accounted for 44, 52 and 42%. On the other hand, the histamine content in non-irradiated sausage by 90 days of storage (i.e. 109.12 mg/kgDW) clearly exceeded the maximum allowable of 50 mg/kg, unlike happened in their irradiated counterparts. Therefore, the dramatic reduction observed in the histamine levels suggests use of this preservation technique for that traditional meat food. (author)

    Full Text Available Duchenne muscular dystrophy (DMD and Becker muscular dystrophy (BMD are allelic disorders caused by mutations within the dystrophin gene. Our study has identified 100 Egyptian families collected from the Human Genetics Clinic, National Research Center, Cairo. All cases were subjected to complete clinical evaluation pedigree analysis, electromyography studies, estimation of serum creatine phosphokinase enzyme (CPK levels and DNA analysis. Multiplex PCR using 18 pairs of specific primers were used for screening of deletion mutations within the dystrophin gene. A frequency of 55% among the families. Sixty per cent of detected deletions involved multiple exons spanning the major or the minor hot spot of the dystrophin gene. The remainder 40% which mainly involved exon 45. Comparing these findings with frequencies of other countries it was found that our figures fall within the reported range of 40%– for deletions. The distribution of deletions in our study and other different studies was variable and specific ethnic differences do not apparently account for specific deletions. In addition this study concluded that employment of the 18 exon analysis is a cost effective and a highly accurate (97% to launch a nationwide program.

    Full Text Available Heart disease is the leading cause of mortality and one of the main causes of morbidity in beta-thalassemia. Patients with homozygous thalassemia may have either a severe phenotype which is usually transfusion dependent or a milder form that is thalassemia intermedia.  The two main factors that determine cardiac disease in homozygous β thalassemia are the high output state that results from chronic tissue hypoxia, hypoxia-induced compensatory reactions and iron overload.  The high output state playing a major role in thalassaemia intermedia and the iron load being more significant in the major form. Arrhythmias, vascular involvement that leads to an increased pulmonary vascular resistance and an increased systemic vascular stiffness and valvular abnormalities also contribute to the cardiac dysfunction in varying degrees according to the severity of the phenotype.  Endocrine abnormalities, infections, renal function and medications can also play a role in the overall cardiac function.  For thalassaemia major, regular and adequate blood transfusions and iron chelation therapy are the mainstays of management. The approach to thalassaemia intermedia, today, is aimed at monitoring for complications and initiating, timely, regular transfusions and/or iron chelation therapy.  Once the patients are on transfusions, then they should be managed in the same way as the thalassaemia major patients.  If cardiac manifestations of dysfunction are present in either form of thalassaemia, high pre transfusion Hb levels need to be maintained in order to reduce cardiac output and appropriate intensive chelation therapy needs to be instituted.  In general recommendations on chelation, today, are usually made according to the Cardiac Magnetic Resonance findings, if available.  With the advances in the latter technology and the ability to tailor chelation therapy according to the MRI findings as well as the availability of three iron chelators, together with

  3. Hegemony for Beginners: Egyptian Activity in the Southern Levant during the Second Half of the Fourth Millennium B.C

    Directory of Open Access Journals (Sweden)

    Branislav Anđelković

    2016-03-01

    Full Text Available After a modest start in the mid-20th century, thousands of Protodynastic Egyptian objects have been unearthed and identified as such in the Southern Levant, including serekh-signs of several Dynasty 0 (Narmer, "Double Falcon", Ny-Hor, IryHor, Ka, and 1st Dynasty (Hor Aha pharaohs. The explanatory models presented so far fail to integrate the totality of the archaeologically manifested parameters, especially considering the impact of the last fifteen years of finds and their contextual and other analysis, into the proper semiotic matrix. The conundrum of Egyptian activity in the Southern Levant displays, at the same time, features of a small-scale trading partner, a colonizer, and a suzerain. Egyptian pottery of local origin provides an indication of a south-north flow of the Egyptian daily-life repertoire of pottery types, or rather their contents, between the Egyptian-related sites, that clearly demonstrates an Egyptian distribution system operating on an intra-regional level in the Early Bronze IB Southern Levant. The ‘Egyptian phenomenon’ is far from being unique since reestablishment of a similar geopolitical pattern, only on a considerably greater scale, can be recognized during the New Kingdom – the Egyptian province in Asia.

    Full Text Available Background and Objectives: Hemoglobinopathies are autosomal recessive inherited diseases more commonly seen in Mediterranean countries. Hereditary blood diseases including B-thalassemia and sickle cell anemia are important health problems. In our study we aimed to analyze the results of the premarital hemoglobinopathy screening test for a 6 years period in Hatay region. Material and Methods: The study sample comprised the couples attending to the Mother and Child Health Care Center in Hatay for premarital hemoglobinopathy screening from 2004 to 2009. Hemoglobin chain analyses of 87.830 couples were evaluated. RESULTS: 175.660 people were screened at total. The prevalence of beta thalassemia trait, sickle cell anemia trait, sickle cell anemia, beta thalassemia major, beta-thalassemia intermedia, alpha-thalassemia, alpha-thalassemia trait was found as 13.921 (7,9%, 6.074 (3,4%, 631 (0.35%, 132 (0.07%, 118 (0.06%, 9 (0.005%, 150 (0.08% respectively. 72 newborns with beta-thalassemia were diagnosed as a result of the marriage of the carrier couples in 6 years. Conclusions: Hatay is a high risk region for beta-thalassemia and sickle cell anemia trait. In countries with high prevalence of hemoglobinopathies, a premarital screening program and counseling is needed to decrease the prevalence.

    The clinical manifestations associated with H5N1 infection in humans range from asymptomatic infection to mild upper respiratory illness, severe pneumonia, and multiple organ failure. The ratio of symptomatic cases to asymptomatic cases is not known, because it is not possible to precisely define the number of asymptomatic cases. A total of 97 cases suffering from avian flu were suspected based on history taking, demographic data, clinical manifestations, laboratory and radiological investigations. The followings were done for all cases; complete blood picture (differential leucocytic count), coagulation profile, renal and liver function tests. H5N1 influenza virus was diagnosed thorough PCR technique. Changes in arterial blood gases and repeated chest X-rays were reported frequently. All patients were given specific antiviral therapy (oseltamivir). The study described the clinical picture and laboratory results of 81 confirmed avian influenza human cases in an Egyptian hospital (Abassia chest hospital), and reviewed the avian influenza current situation covering from March 2006 to June 2009 with very high pick in the first half of 2009. The significant apparent symptoms were fever as initial and main symptom (93.75%), followed by shortness of breathing (73%), cough (66.6%), muscle & joint pain (60%) and sore throat (40%).

    By conducting a case-control study in two university hospitals, we explored the association between modifiable risk behaviours and diarrhoea. Children aged bacterial pathogens using standard techniques and tested by ELISA to detect rotavirus and Cryptosporidium spp. Four hundred cases and controls were enrolled between 2007 and 2009. The strongest independent risk factors for diarrhoea were: presence of another household member with diarrhoea [matched odds ratio (mOR) 4.9, 95% CI 2.8-8.4] in the week preceding the survey, introduction to a new kind of food (mOR 3, 95% CI 1.7-5.4), and the child being cared for outside home (mOR 2.6, 95% CI 1.3-5.2). While these risk factors are not identifiable, in some age groups more easily modifiable risk factors were identified including: having no soap for handwashing (mOR 6.3, 95% CI 1.2-33.9) for children aged 7-12 months, and pacifier use (mOR 1.9, 95% CI 1.0-3.5) in children aged 0-6 months. In total, the findings of this study suggest that community-based interventions to improve practices related to sanitation and hygiene, handwashing and food could be utilized to reduce the burden of diarrhoea in Egyptian children aged <5 years.

    Human skin is a large, complex ecosystem that harbors diverse microbial communities. The rapid advances in molecular techniques facilitate the exploration of skin associated bacterial populations. The objective of this study was to perform a preliminary characterization of skin associated bacterial populations in Egyptian individuals. Samples were collected from five healthy subjects from two skin sites; Antecubital Fossa (AF) and Popliteal Fossa (PF). Genomic DNA was extracted and used to amplify bacterial 16S rRNA genes which were sequenced on Illumina MiSeq platform. The two sites showed distinct diversity where PF was more diverse than AF. Taxonomic analysis of sequences revealed four main phyla Proteobacteria, Firmicutes, Actinobacteria and Deinococcus-Thermus, with Proteobacteria presenting the highest diversity. Klebsiella, Bacillus, Pseudomonas and Escherichia were the most predominant genera. Our data suggest that environmental factors can shape the composition of the skin microbiome in certain geographical regions. This study presents a new insight for subsequent analyses of human microbiome in Egypt. PMID:27545210

    Full Text Available Abstract Background There are no published data on peanut sensitization in Egypt and the problem of peanut allergy seems underestimated. We sought to screen for peanut sensitization in a group of atopic Egyptian children in relation to their phenotypic manifestations. Methods We consecutively enrolled 100 allergic children; 2-10 years old (mean 6.5 yr. The study measurements included clinical evaluation for site of allergy, possible precipitating factors, consumption of peanuts (starting age and last consumption, duration of breast feeding, current treatment, and family history of allergy as well as skin prick testing with a commercial peanut extract, and serum peanut specific and total IgE estimation. Children who were found sensitized to peanuts were subjected to an open oral peanut challenge test taking all necessary precautions. Results Seven subjects (7% were sensitized and three out of six of them had positive oral challenge denoting allergy to peanuts. The sensitization rates did not vary significantly with gender, age, family history of allergy, breast feeding duration, clinical form of allergy, serum total IgE, or absolute eosinophil count. All peanut sensitive subjects had skin with or without respiratory allergy. Conclusions Peanut allergy does not seem to be rare in atopic children in Egypt. Skin prick and specific IgE testing are effective screening tools to determine candidates for peanut oral challenging. Wider scale multicenter population-based studies are needed to assess the prevalence of peanut allergy and its clinical correlates in our country.

    The cement industry is considered as one of the basic industries that plays an important role in the national economy of developing countries. Activity concentration of 238U, 232Th, and 40K in local cement types from different Egyptian factories has been measured using a shielded HPGe detector. The average values obtained for 238U, 232Th, and 40K activity concentrations in different types of cement are lower than the corresponding global values reported in UNSCEAR publications. On the basis of the hazard index and the radium equivalent concentration, it can be shown that the natural radioactivity of cement samples is not greater than the values permitted in the established standards in other countries. A solid-state nuclear track detector SSNTD (Cr-39) was used to measure the radon concentration as well as exhalation rate for these samples. The effective radium content and the exhalation rate are found to vary from 12.75 to 38.52 Bq kg(-1) and 61.19 to 181.39 Bq m(-2) d(-1), respectively.

    Full Text Available E-commerce has been predicted to be a new driver of economic growth for developing countries. The SME sector plays a significant role in its contribution to the national economy in terms of the wealth created and the number of people employed. Small and Medium Enterprises (SMEs in Egypt represent the greatest share of the productive units of the Egyptian economy and the current national policy directions address ways and means of developing the capacities of SMEs. Many factors could be responsible for the low usage of e-commerce among the SMEs in Egypt. In order to determine the factors that promote the adoption of e-commerce, SMEs adopters and non-adopters of e-commerce were asked to indicate the factors inhibiting the adoption of e-commerce. The results show that technical barriers are the most important barriers followed by legal and regulatory barriers, whereas lack of Internet security is the highest barrier that inhibit the implementation of e-commerce in SMEs in Egypt followed by limited use of Internet banking and web portals by SMEs. Also, findings implied that more efforts are needed to help and encourage SMEs in Egypt to speed up e-commerce adoption, particularly the more advanced applications.

    Full Text Available This paper reviews data mining applications of students' databases in educational institutions. Data mining techniques that predict and improve students' retention rates and success is presented. Moreover, the Missions Administration at the Ministry of Higher Education in Egypt and previous analysis done on the missions databases is described. The paper further describes the methodology used for analyzing the database for the ministry of higher education in Egypt. The process starts by extracting a subset of data including the missioners and the mission’s data, countries, specialties, departure and arrival dates and finally the extension requests from the missioners. These data were extracted into a data warehouse for the analysis purpose. The used model discovered the best and the worst countries for student mission. A detailed analysis discovered the best and the worst specialties in the previously discovered countries.Moreover, the analysis revealed the effect of the marital status on the mission of students in foreign countries. A visual display using a chart was used to express the information to business users. This model may help in achieving effective decision making in the reallocation of Egyptian students to other countries.

  12. Effect of breeding conditions on thyroid and sex hormones of pregnant and lactating Egyptian buffaloes

    International Nuclear Information System (INIS)

    The present investigation was planned in order to clarify the effect of breeding conditions on the thyroid and sex hormones of Egyptian female buffaloes during gestation. Parturition and lactation. Serum levels of triiodothyronine (T3), thyroxine (T4), estradiol and progesterone were studied in two groups of buffaloes, aging 5-7 years.Starting from the 5th month of gestation till the 9th week of lactation. The first group was maintained on standard farm conditions and the second on ordinary traditional village conditions. The data revealed that the way of breeding has no effect on thyroid and sex hormones and no differences were observed. Accordingly, pregnancy and lactation were not affected. These results indicate that the Egyptian buffaloes have high adaptability towards the surrounding conditions so, its worthy to breed such beneficial animals without any additional effort or expenses. These factors should be considered for improving the Egyptian economy

    Full Text Available BACKGROUND: The incidence of Down syndrome (DS in Egypt varies between 1:555 and 1:770 and its screening by triple test is becoming increasingly popular nowadays. Results, however, seem inaccurate due to the lack of Egyptian-specific information needed for risk calculation and a clear policy for programme implementation. Our study aimed at calculation and validation of the triple marker medians used in screening Egyptian females as well as to recommend programme conventions to unify screening in this country. METHODS: The study was conducted on 668 Egyptian women, in weeks 15-20 of pregnancy as proven by sonar. Chorionic gonadotropin (CG, α-fetoprotein (AFP and unconjugated oestriol (uE3 were measured on Siemens Immulite analyzer. Medians of the three parameters were calculated, regressed against gestational age (GA and weighted by the number of participants/week. Equations were derived to adjust each parameter to the maternal weight and were centered on the median Egyptian weight. Prisca software was fed with the above data, multiples-of-median (MoM and DS risks were calculated and the screening performance was evaluated at a mid-trimester risk cutoff of 1:270. RESULTS: Log-linear [AFP/uE3 = 10(A+B*GA] and exponential equations [CG = A*e (B*GA] were derived and the regressed medians were found to follow similar patterns to other Asian and Western medians. Oestriol was always lowest (even halved while CG and AFP were intermediate. A linear reciprocal model best fitted weight distribution among Egyptians and successfully adjusted each parameter to a weight of 78.2 kg. Epidemiological monitoring of these recommendations revealed satisfactory performance in terms of 6.7% initial positive rate and 1.00 grand MoM. CONCLUSIONS: Adoption of the above recommendations is hoped to pave the way to a successful DS screening programme tailored to Egyptian peculiarities.

    The Archeological museum in Zagreb treasures the linen strips of an Egyptian mummy with inscriptions in Etruscan, and an Egyptian medical papyrus. The Etruscan text has been deciphered, but only a small part has been translated. This religious-magical ceremonial might be in relation with theurgical measures for health protection, promotion and restitution. The medical text on the papyrus is a hieratic script dating back to Pharaonic New Kingdom, probably a fragment of a medicine book similar to the Ebers papyrus. This article provides its transcription and translation. Three recipes for a powder and ointments which were used in the local treatment of inflammed moist skin lesions are presented. PMID:8656978

    Full Text Available The purpose of this study was to investigate the relationships between employee perception of equity and job satisfaction in the Egyptian private universities. Data were gathered using a face-to-face survey of 80 teaching staff members at three Egyptian universities. Findings revealed positive relationships between perceptions of equity, where a "motivator" was the outcome in the comparison, and job satisfaction. The study also revealed that there was no relationship between perceptions of equity and job satisfaction where a "hygiene factor" was the outcome in the comparison. This study is exploratory and findings are not conclusive. Its implications and limitations are discussed.

    The mathematics of ancient Egypt was fundamentally different from our math today. Contrary to what people might think, it wasn't a primitive forerunner of modern mathematics. In fact, it can't be understood using our current computational methods. Count Like an Egyptian provides a fun, hands-on introduction to the intuitive and often-surprising art of ancient Egyptian math. David Reimer guides you step-by-step through addition, subtraction, multiplication, and more. He even shows you how fractions and decimals may have been calculated-they technically didn't exist in the land of the pharaohs.

    Delta-Beta thalassaemia is an unusual variant of thalassaemia with elevated level of foetal haemoglobin (HbF). The clinical presentation of delta-beta thalassaemia is mild in both heterozygote and homozygote cases. We hereby describe a rare cause of elevated Hb F in a father and his two daughters. A 52-year-old diabetic male patient, on evaluation of chromatogram of cation exchange HPLC for HbA1c, we incidentally identified elevated Hb F of approximately 20%. Haematological investigation of the patient revealed decreased haemoglobin, normal RBC, leucocyte and platelet count, decreased MCV and MCH. Red cell morphology showed predominantly normocytic normochromic cells with mild anisopoikilocytosis, few microcytes and hypochromic cells seen. His liver function test was normal. Haemoglobin variant analysis revealed decreased Hb A (79.4%), normal Hb A2 (2%) and increased Hb F (19.75%). A possible diagnosis of heterozygous δ β-thalassaemia was considered. Since most laboratories perform HbA1c by cation exchange HPLC method, a careful evaluation of the chromatogram yields useful information. In our case, the elevated Hb F in a father and further careful evaluation of clinical and haematological parameters in the family members made us to possibly think of rare disorders like heterozygous Delta-Beta thalassaemia in the family and provide valuable genetic counseling.

    Congenital dyserythropoietic anemia type I is an autosomal recessive disorder associated with macrocytic anemia, ineffective erythropoiesis, iron overloading and characterized by abnormal chromatin ultrastructure in erythroblasts such as internuclear chromatin bridges, spongy heterochromatin and invagination of the nuclear membrane. A 58-year-old Causasian man with chronic hemolytic anemia, heterozygous for β (+) -globin IVS1, nt110 G>A mutation (causing abnormal alpha:beta globin chain ratio) showed clinical, laboratory and hematological features suggesting diagnosis of CDA1. Sequence analysis of CDA-related genes revealed compound heterozygosity for two novel mutations in the CDAN1 gene: a frameshift mutation 3367 del 4 (TTAG) in exon 25 and a missense mutation c.1811 G>T in exon 11 causing an aminoacid change from glycine to valine at codon 565 (G565V). One of the propositus' brothers showed the same gene mutations. As the CDA1 can mimic thalassemia, a frequent misdiagnosis is possible especially in countries where the prevalence of thalassemia is high. A strong clinical suspicion in patients who do not reveal a clear genetic basis for presumed thalassemia may help clinch the correct diagnosis. PMID:27408412

    Full Text Available Most common microcytic hypochromic anemias are iron deficiency anemia (IDA and β-thalassemia trait (BTT, in which oxidative stress (OxS has an essential role. Catalase causes detoxification of H2O2 in cells, and it is an indispensable antioxidant enzyme. The study was designed to measure erythrocyte catalase activity (ECAT in patients with IDA (10 or BTT (21, to relate it with thalassemia mutation type (β0 or β+ and to compare it with normal subjects (67. Ninety-eight individuals were analyzed since September 2013 to June 2014 in Tucumán, Argentina. Total blood count, hemoglobin electrophoresis at alkaline pH, HbA2, catalase, and iron status were performed. β-thalassemic mutations were determined by real-time PCR. Normal range for ECAT was 70,0–130,0 MU/L. ECAT was increased in 14% (3/21 of BTT subjects and decreased in 40% (4/10 of those with IDA. No significant difference (p=0,245 was shown between normal and BTT groups, while between IDA and normal groups the difference was proved to be significant (p=0,000. In β0 and β+ groups, no significant difference (p=0,359 was observed. An altered ECAT was detected in IDA and BTT. These results will help to clarify how the catalase activity works in these anemia types.

    The spinal cord, brain, optic nerves and peripheral nerves may be affected by vitamin B12 (cobalamin) deficiency. Deficiency of vitamin B12 also causes megaloblastic anaemia, meaning that the red blood cells are usually larger than normal. In this paper we report a 16-year old girl who was referred to us for the evaluation of mild paraparesis and paresthesias marked by tingling "pins and needles" feelings and general weakness. The patient, her parents and sisters were on a strict vegan diet, which made us believe that vitamin B12 deficiency may be the possible cause of the neurologic clinical manifestations. The serum level of vitamin B12 was low, but there was no macrocytosis in the routine blood examination. The electrophoresis of haemoglobin was pathologic, there was 3.7% of HbA2 and 11.6% of HbF (heterozygous form of beta-thalassaemia). When megaloblastic anaemia occurs in combination with a condition that gives rise to microcytic anaemia, many megaloblastic features may be masked. Instead of being macrocytic, the anaemia could be normocytic or even microcytic. Vitamin B12 deficiency is a diagnosis that must not be overlooked. This case report turns the light on the fact that increased MCV is a hallmark in vitamin B12 deficiency, but it is not an obligatory sign.

    Gaucher disease is the most frequent lysosomal storage disorder. Bone and lung involvement are two major causes of morbidity in this disease. D-dimer is a reliable indicator of active microvascular thrombosis, even in patients without overt hypercoagulation. This study aimed to assess D-dimer levels in Gaucher disease, correlating this marker to clinical characteristics and radiological parameters to investigate its role as a potential predictor for the occurrence and severity of skeletal and pulmonary manifestations. The study population consisted of 56 Egyptian patients with Gaucher disease, 36 had type 1 Gaucher disease (64.3%) and 20 had type 3 Gaucher disease (35.7%). Thirty healthy individuals were enrolled as a control group. D-dimer levels were significantly higher in all patients with Gaucher disease compared with controls (P < 0.001). Patients with type 3 showed significantly higher D-dimer concentrations compared with type 1 (P < 0.001). Pulmonary involvement was present in a significant proportion among type 3 Gaucher patients (P < 0.05), whereas bone changes were present in a higher percentage in type 1 compared with type 3 Gaucher patients. D-dimers were significantly higher in patients with abnormal MRI findings of the long bones and in those with ground glass appearance on high-resolution computerized tomography of the chest compared with patients with normal radiology (P < 0.001). Splenectomized patients displayed significantly higher D-dimer levels compared with nonsplenectomized patients (P < 0.001). Our results suggest that D-dimer is significantly elevated in Gaucher disease, particularly type 3, and may be considered as a potential marker of risk prediction of bone and lung involvement that could be used to monitor treatment response.

  4. Cytokine Gene Polymorphisms in Egyptian Cases with Brain Tumors

    International Nuclear Information System (INIS)

    Background: Cytokines are proposed to play important roles in brain tumor biology as well as neuro degeneration or impaired neuronal function. Objectives: This work aimed to check the association of polymorphisms of cytokine genes in Egyptian cases with brain tumors. Methods: This work included 45 cases affected by brain tumors diagnosed as 24 benign and 21 malignant. Their median age was 45 years, and they were 20 males and 25 females. These cases were taken randomly from the Neurosurgery Department of Mansoura University Hospital, Egypt. Case genotypes were compared to 98 healthy unrelated controls from the same locality. DNA was amplified using PCR utilizing sequence specific primers (SSP) for detection of polymorphisms related to TNF-a-308 (G/A), IL-10-1082 (G/A), IL-6-174 (G/C) and IL-1Ra (VNTR) genes. Results: Cases affected with benign brain tumors showed a significant higher frequency of IL-10-1082 A/A [odds ratio (OR=8.0), p<0.001] and IL-6-174 C/C (OR=6.3, p=0.002) homozygous genotypes as compared to controls. Malignant cases, on the other hand, showed significantly higher frequency of IL-6-174 C/C (OR =4.8, p=0.002) homozygous genotype and TNF-a-308 A/A (OR=4.9, p<0.001) homozygous genotype when compared to controls. In the meantime, all cases showed no significant difference regarding the distribution of IL-1Ra VNTR genotype polymorphism compared to controls. Conclusions: Cytokine gene polymorphisms showed a pattern of association with brain tumors which may have potential impact on family counseling and disease management.

    Egypt is considered one of the most countries which contain a lot of cultural heritage; the Ancient Egyptian used a lot of stones for his life like: limestone, sandstone, granite and Egyptian Alabaster. The Egyptian Alabaster is used for his daily and eternal life, he made a lot of funerary furniture from this stone like: vessels, statues, Architectural elements in the temples, tombs and canopic jars to preserve his viscera from decomposition like: stomach, liver … etc in the mummification process. Egyptian Alabaster is a sedimentary rock especially chemical- origin sedimentary rocks, it deposits inside caves and around springs which consists of calcium carbonates (CaCO3), they are very fragile "hardness = 3 in Mohs hardness scale". The Egyptian Alabaster vessels expose to a lot of deterioration factors in the burial and exposure environment after excavation. The study case vessels are made of Egyptian alabaster stone and belong to the early era (First and second Egyptian dynasties) in Atfiyah museum store, these vessels exposed to a lot of deterioration factors in the burial and exposure environment like: soil pressure, air temperature variety, relative humidity and salts. The vessels are conserved at the restoration laboratory in Atfiyah museum store by a lot of restoration and conservation processes like: cleaning - consolidation - assembling process for the separated parts and completion for the lost parts.

    The ancient Egyptians mummified an abundance of cats during the Late Period (664 - 332 BC). The overlapping morphology and sizes of developing wildcats and domestic cats confounds the identity of mummified cat species. Genetic analyses should support mummy identification and was conducted on two long bones and a mandible of three cats that were mummified by the ancient Egyptians. The mummy DNA was extracted in a dedicated ancient DNA laboratory at the University of California - Davis, then directly sequencing between 246 and 402 bp of the mtDNA control region from each bone. When compared to a dataset of wildcats (Felis silvestris silvestris, F. s. tristrami, and F. chaus) as well as a previously published worldwide dataset of modern domestic cat samples, including Egypt, the DNA evidence suggests the three mummies represent common contemporary domestic cat mitotypes prevalent in modern Egypt and the Middle East. Divergence estimates date the origin of the mummies' mitotypes to between two and 7.5 thousand years prior to their mummification, likely prior to or during Egyptian Predyanstic and Early Dynastic Periods. These data are the first genetic evidence supporting that the ancient Egyptians used domesticated cats, F. s. catus, for votive mummies, and likely implies cats were domesticated prior to extensive mummification of cats.

    2015-06-01

    Full Text Available Public opinion leaders and activists characterized the Egyptian “Arab Spring” of January 2011 as a “Facebook Revolution”. They highlight the intrinsic power of social media as an influencing factor for social change. Undeniably, social media played important roles in that revolution process. However, these roles cannot be disconnected from the socio-political contexts. This paper discusses the use of social media, particularly of Facebook, by the April 6th Youth Movement (A6YM, a decisive actor of the Egyptian protests. It is based on the analysis of two Egyptian newspapers and one American newspaper, between 2008 and 2011. We propose that a social media provided alternative mechanisms for political expression and organization, b social media contributed to the genesis and consolidation of the A6YM and to the establishment of youth political identities, and c the combination of “bits and streets” amplified not just the movement’s mobilization but the degree of opposition experienced by the Egyptian regime.

    Full Text Available Egypt is one of the important orange exporters and Saudi Arabia also is an important import orange market. The Saudi orange market is a main market for Egypt which has a market share that exceeds half of Saudi orange market by 55.72%. This article aims to discover the degree of market power for Egyptian orange exports and other competitors in the Saudi market and if it is considered a measure of the relative mark- up by applying Residual Demand Elasticity approach. The results show that Egyptian orange exports has just a statistically signified market power by SUR and 3-SLS and has a negative sign, which may gain monopolistic profits by the relative mark-up over its marginal cost by about 63.7% without losing any of its market share. The source of Egyptian orange exports market power is due to: 1- product differentiation where Egypt exports navel orange most its export season compared with sweet orange which exported from other competitors. 2- Saudi Arabia Market demand characteristics which reflect on the consumers preference for Egyptian oranges.

    2015-06-01

    Full Text Available The Egyptian rousette bat (Rousettus aegyptiacus is a natural reservoir for marburgviruses and a consistent source of virus spillover to humans. Cumulative evidence suggests various bat species may also transmit ebolaviruses. We investigated the susceptibility of Egyptian rousettes to each of the five known ebolaviruses (Sudan, Ebola, Bundibugyo, Taï Forest, and Reston, and compared findings with Marburg virus. In a pilot study, groups of four juvenile bats were inoculated with one of the ebolaviruses or Marburg virus. In ebolavirus groups, viral RNA tissue distribution was limited, and no bat became viremic. Sudan viral RNA was slightly more widespread, spurring a second, 15-day Sudan virus serial euthanasia study. Low levels of Sudan viral RNA disseminated to multiple tissues at early time points, but there was no viremia or shedding. In contrast, Marburg virus RNA was widely disseminated, with viremia, oral and rectal shedding, and antigen in spleen and liver. This is the first experimental infection study comparing tissue tropism, viral shedding, and clinical and pathologic effects of six different filoviruses in the Egyptian rousette, a known marburgvirus reservoir. Our results suggest Egyptian rousettes are unlikely sources for ebolaviruses in nature, and support a possible single filovirus—single reservoir host relationship.

    The ancient Egyptians left an impressive artistic legacy documenting many aspects of their society including the existence of dwarfs as highly valued members. In previous publications in the Journal, I discussed dwarfs and skeletal dysplasia in ancient Egypt. In this study, I examined the ancient Egyptian representations of dwarfs of the Walters Art Museum in Baltimore, Maryland. One of the highlights of the collection is a group of five ivory figurines from Predynastic Times (pre 3500-3100 BCE) depicting a couple, a man with a child, and two females. Representations from other periods include ordinary as well as dwarf deities. The dwarf gods, Bes and Ptah, are frequently depicted holding or biting snakes or standing on crocodiles symbolizing their ability to ward off dangers. A couple of statuettes from the Greco-Roman Period that, in contrast to earlier Egyptian Periods, depict harsh physical anomalies, twisted bodies, and facial pain. The artistic impression can be interpreted as either tragic or humorous. The grotesque depiction of dwarfs during the Greco-Roman Period in ancient Egypt is believed to be due to a greater infusion of Hellenistic influence. This study provides a microcosm of the legacy of dwarfs in ancient Egypt and supports the premise that dwarfs were accepted and integrated in the ancient Egyptian society, and with a few exceptions, their disorder was not depicted as a physical handicap.

    The Nile River remains the most important source of freshwater for Egypt as it accounts for nearly all of the country's drinking and irrigation water. About 95% of the total population is accounted to live along the Banks of the Nile(1). Therefore, water quality deterioration in addition to general natural scarcity of water in the region(2) is the main driver for carrying out this study. What further aggravates this issue is the water conflict in the Blue Nile region. The study evaluates different water quality parameters and their concentrations in the Egyptian Nile; further assessing the temporal dynamics of water quality in the area with (a) the Environmental Kuznets Curve (EKC)(3) and (b) the Jevons Paradox (JP)(4) in order to identify water quality improvements or degradations using selected socioeconomic variables(5). For this purpose various environmental indicators including BOD, COD, DO, Phosphorus and TDS were plotted against different economic variables including Population, Gross Domestic Product (GDP), Annual Fresh Water Withdrawal and Improved Water Source. Mathematically, this was expressed by 2nd and 3rd degree polynomial regressions generating the EKC and JP respectively. The basic goal of the regression analysis is to model and highlight the dynamic trend of water quality indicators in relation to their established permissible limits, which will allow the identification of optimal future water quality policies. The results clearly indicate that the dependency of water quality indicators on socioeconomic variables differs for every indicator; while COD was above the permissible limits in all the cases despite of its decreasing trend in each case, BOD and phosphate signified increasing concentrations for the future, if they continue to follow the present trend. This could be an indication of rebound effect explained by the Jevons Paradox i.e. water quality deterioration after its improvement, either due to increase of population or intensification

    We have identified the beta-thalassemia mutations in 59 patients with thalassemia major and 47 patients with Hb E-beta-thalassemia, and the deletional and nondeletional alpha-thalassemia determinants in 23 out of 24 patients with Hb H disease. All persons were attending the Haematology Clinic at the National University of Malaysia in Kuala Lumpur (Malaysia). Most patients (76) were of Malay descent, while 52 patients were Chinese, and two came from elsewhere. The most frequently occurring beta-thalassemia alleles among the Malay patients were IVS-I-5 (G----C) and G----A at codon 26 (Hb E), while a few others were present at lower frequencies. The Chinese patients carried the mutation characteristic for Chinese [mainly codons 41/42 (-TTCT) and IVS-II-654 (C----T)]; Malay mutations were not observed among Chinese and Chinese mutations were virtually absent in the Malay patients. The large group of patients with Hb E-beta-thalassemia and different beta-thalassemia alleles offered the opportunity of comparing hematological data; information obtained for patients with Hb E-beta-thalassemia living in other countries was included in this comparison. Twenty-three patients with Hb H disease carried the Southeast Asian (SEA) alpha-thalassemia-1 deletion; 13 had the alpha CS alpha (Constant Spring) nondeletional alpha-thalassemia-2 determinant, while the deletional alpha-thalassemia-2 (-3.7 or -4.2 kb) was present in 10 subjects. The --/alpha CS alpha condition appeared to be the most severe with higher Hb H values. Both deletional and nondeletional types of alpha-thalassemia-2 were seen among Malay and Chinese patients.

  15. The Impact of Diabetes on Serum Osteocalcin in Egyptian Children

    International Nuclear Information System (INIS)

    Diabetes may affect bone via bone structure, bone density, and biochemical markers of bone turnover. Lack of diagnosis and treatment of alterations of the bone tissue metabolism in type1diabetes (T1D) may lead to osteoporosis.T1D most often starts before achieving peak bone mass.Recent studies have revealed that, in T1D fracture risk is increased more than expected from the degree of decrease in bone mineral density (BMD).Osteocalcin (OC) is considered a useful biochemical marker of bone formation. As in T1D, there is absolute insulin deficiency but insulin sensitivity remains generally intact. Therefore, this study was conducted to evaluate the association between OC levels in relation the degree of residual β-cell function and other metabolic parameters in T1D In the present study, the impact of diabetes on serum OC in Egyptian children and adolescents was evaluated by comparing serum level of OC in T1D (30 subjects) and age-matched non-diabetic control (15 subjects). The present study showed that, patients with T1D had lower OC serum levels compared to the controls (7.67 ± 3.55, 21.82 ± 4.96 μg/ml respectively, p < 0.001) with a lower OC levels in diabetic females than in diabetic males (5.92 ± 3.12, 8.74 ± 2.84 μg/ml respectively, p < 0.001) and lower OC levels in pre-pubertal than pubertal diabetic patients in both genders with p < 0.05. Serum OC levels in T1D correlated with HbAIc (p < 0.001), BMI (p < 0.05), durations of T1D (p < 0.05) and total daily insulin dose (p < 0.05)and did not correlate with C-peptide levels . It may be concluded that serum OC levels in patients with T1D are regulated by a variety of developmental and metabolic pathways. Since OC levels correlated with exogenous insulin(daily insulin dose) and did not correlate with endogenous insulin (C-peptide levels), therefore, it is presumed that OC was regulated by insulin-mediated events, in presence of aggressive autoimmune destruction of pancreatic cell. These results proposed that

    Full Text Available Milk and dairy products is considered the most complete foodstuff that provide human either infants or adults with most of their vital needs. Milk and cheese have high nutritive value due to its high content of protein, fat, minerals especially calcium (Ca2+ & phosphorous, and vitamins. Two hundred samples produced and sold in Egypt during 2001-2003 were collected from allover the country. The cheese samples were subjected to microbiological and chemical analysis. Samples were microbiologically tested for total aerobic bacterial count (TABC, Colifrm, Escherichia coli (E. coli, Staphylococcus aureus, mould and yeast, salmonella and shigella, and listeria species. Protein, fat, carbohydrates, moisture, ash, lactose, Calcium (Ca, phosphorous (P and Ca/P were evaluated. The analysis showed that total aerobic bacterial count did not exceed 1.4X105±1.7X105 cells/gm, which is close to what allowed by the Standard Egyptian Guidelines (2001 and 47.5 % of the tested cheese are free from coliform bacteria and Escherichia coli. Ninety-eight and half percent, 97 %, 97 % and 91.5 % of the tested cheese (kareish, feta, thalaga, double cream respectively, either made in plant or home or farmers' cheese sample have zero Staphylococcus aureus count or mould and yeast; or salmonella and shigella, or listeria species respectively, i. e. free from them. Double cream cheese has the lowest protein content (7.79±0.78 gm% while kareish cheese has the highest protein content (19.99±1.32 gm%, but for fat content the opposite is true, double cream cheese have the highest fat content (24.56±1.78 gm% while kareish cheese have the lowest fat content (3.87±0.97 gm %. Feta cheese has high ash content while kareish cheese has the highest moisture content with the lowest ash content (68.97±1.86 & 1.81±0.47 gm% respectively. Lactose content varies widely from 1.50±0.26 (double cream cheese to 3.25±0.50 (feta cheese. Kareish cheese has higher content of calcium and

  17. THE GENIUS LOCI AT THE GREAT TEMPLE OF ABU SIMBEL: HERMENEUTIC READING IN THE ARCHITECTURAL LANGUAGE OF ANCIENT EGYPTIAN TEMPLES OF RAMSES II IN NUBIA

    2015-06-01

    Full Text Available Archaeologists have long wondered about the Temple of Abu Simbel: its location within the Nubian territory far from major Egyptian cities, and its unique design. Utilizing the hermeneutic process of understanding the whole from the parts and then situating the whole within a bigger whole (context, this study is a trial to arrive at a better interpretation of this monument. Drawing on the characteristic analysis of the temple's Genius Loci as developed by Norberg-Schulz, as well as on Heidegger's anticipatory fore-structures, the study goes on to show that both of the location and the unique structure of the temple were the outcome of political and conceptual aspects of the period, more than being a religious tradition. Reaching this conclusion, another goal had been achieved, where the validity of hermeneutic analyses as a useful tool for discovering new dimensions about historical monuments and archaeological sites had been attested.

  18. Patterns of ovarian and oestrous activity and induction of cyclic activity during the post-partum period in Egyptian buffaloes

    International Nuclear Information System (INIS)

    This report covers three studies. In the first study, ovarian and oestrous activity were monitored in 47 buffaloes for 90 days following parturition. Failure to resume ovarian cyclicity after calving was found to be the main reason for the delay in conception. High incidence of ovulatory anoestrus (64%) constitutes also a major problem in Egyptian buffaloes. In the second study, buffaloes with inactive ovaries were treated at 90 days post-partum with either GnRH or progesterone, given either intravaginally (PRID) or orally (CAP). Both GnRH and PRID were effective in inducing ovulation but GnRH administration was followed by a high incidence of silent ovulation. Within the 35 days following treatment, about 50% of the PRID treated animals got in calf vs. 44 and 22% for GnRH and CAP treated animals, respectively. In the third study, buffaloes were treated with either 6 or 12μg GnRH at either 7 or 15 days post-partum. GnRH treatment resulted in significant reductions in the intervals from calving to first ovulation, first detected oestrus and time to first rise in serum progesterone concentration (> 1 ng/mL).

    The aim of this study was to investigate the pattern of basic and sport nutrition as well as perspectives of young Egyptian athletes. Structured interview survey measuring knowledge, attitudes, beliefs and behaviors about basic and sport nutrition was administered to adolescent athletes recruited from 4 sport clubs and 2 fitness centers in Greater Cairo governorate. A total of 358 participants aged 13-18 years completed questionnaires. Basic nutrition knowledge was reasonable in almost all domains except fast food. Fixed breakfast (78.5%), home meals (lunch, 70.7%), and healthy snacks (55.8%) were the most positive features of the basic dietary pattern. More than 70% perceived themselves as knowledgeable about sport nutrition. The prevalence rate of sport supplement intake was (48.9%, n = 175), predominantly sport drinks (66.9%) and creatine (54.3%). Coaches were the primary source of sport nutrition information. Forty-four percent of participants (n = 77/175) reported supplement consumption during competition seasons only. Better physical appearance and enhancement of athletic performance were the major motivations for supplement intake. These findings indicate the necessity of a comprehensive nutrition education program targeting not only athletes and parents, but also coaching staff, health trainers and all sport team officials.

    Rokia Abd ElShafy Soliman El-Banna*, , Azza Mohamed Sarry El-Din*, Fatma Ahmed Eid**, Walaa Yousef Mohamed Ali

    2014-04-01

    Full Text Available Background: Vitamin D deficiency is considered to be the most common nutritional deficiency and also one of the most common undiagnosed medical conditions in the world. Vitamin D is naturally present only in minor amounts in most foods; the great majority is synthesized by the action of ultraviolet light on chemical precursors in the skin. The manifestation of vitamin D deficiency in sub adults is referred to as rickets, and in adults, osteomalacia . Rickets and osteomalacia are the sub adult and adult expressions of a disease in which the underlying problem is a failure to mineralize bone protein (osteoid. The most common cause of this disease is a physiological deficiency in vitamin D. The associated problems include deformed bones. Material and Methods: This study aimed to investigate the skeletal remains of ancient Egyptians from Baharia Oasis population for lesions indicative of vitamin D deficiency (rickets and osteomalacia. The material consisted of 1075 commingled bones (38 sub adults and1037 adults. They were recovered from Baharia oasis. Results: The results showed that, there was no evidence of rickets in sub adult group. The prevalence of osteomalacia in adult Baharia populations was 7.4% ; all were adult males. This result could indicate that this population was subjected to sunlight all over the year and their diet was rich of calcium and phosphorus. Conclusion: These few cases that were found may be due to mechanical stress during wine and textile production.

    Medicine and literature are bound humanistically disciplines from the moment that Man has the necessity to communicate his restlessness, anguish and fears with regard to the presence of illness and death. Medical topics are a frequent resource in literary works in which the writer amalgamates the patient, the doctor, illness, and death from the human point of view. Specifically in the historical quality of the novel, the author is forced nevertheless to be documented thoroughly on the topic on which his work rotate, in such a way that he avoids incorrect historical data, combined with the necessity to give flight to his imagination in the creation of fictitious situations for his narration. Here we analyze as example of the details of medicine in the Egyptian culture beginning with the novel "Sinuhé the Egyptian", as an answer to scientific commentary at an international on congress of neurosurgery.

  4. Non-destructive analysis of ancient Egyptian vitreous materials by neutron activation analysis

    International Nuclear Information System (INIS)

    Chemical compositions of ancient Egyptian glass are one of the key information for identifying the location of the original material for production. The ordinary chemical analysis is however restricted because variable remains can not be destroyed. Thus sensitive analytical method in non-destructive manner is required. The neutron activation analysis was used in this research and the content of Ca, Cl, Al and Mn were found in ancient Egyptian glass and peak area of them were compared with those in the sand samples taken from several areas around Egypt because sand was thought as the raw material of such glasses. As a result, we found three different patterns in chemical compositions in the surrounding sand samples and we expect this pattern might be a good indicator of location of raw sand material.

    Bone marrow necrosis; Egyptian cancer patients Abstract Background: Bone marrow necrosis is a relatively rare entity which has been associated with a poor prognosis. It is most commonly found in patients with neoplastic disorders and severe infections. Methods: study comprised examination of 5043 bone marrow biopsy specimens performed at the National Cancer Institute, Cairo University, over 7 years period (March 2004-March 2011). It included 5 years retrospective (2867 archived samples) and 2 years prospective (2176 samples). Results: Bone marrow necrosis was diagnosed in fifteen out of 5043 examined specimens with a percentage of 0.3% and ranged from mild to massive according to semiquantitative estimation. Prognosis of all patients was poor with survival not exceeding 6 months from the date of marrow necrosis diagnosis. Conclusion: In Egyptian patients, bone marrow necrosis in association with malignancy is a rare disorder which is accompanied by a poor outcome

  6. Characterization of pigments and colors used in ancient Egyptian boat models

    International Nuclear Information System (INIS)

    The analyses of pigments originating from well dated ancient boat models found in Egyptian graves were used for characterization and for dating tasks of unknown objects. A nearly destruction free sampling technique using cotton buds was applied for sampling these valuable artifacts for a subsequent Total Reflection X-Ray Fluorescence Spectrometry (TXRF) analysis. Two relevant collections of Egyptian object of art were at our disposal, one of the Agyptisches Museum Berlin and the second of the British Museum London. Three groups of colors were studied, they originate from white, red and blue/green paints, respectively. The results of the analyses performed on micro-amounts of paints (< 1 μg) show that some artifacts were misclassified and belong to other epochs. Some others were retouched with modern colors. In general, it can be stated that results obtained by Total Reflection X-Ray Fluorescence Spectrometry may dissipate some uncertainties when applying classical archaeological dating methods

    2009-08-01

    The main aim of the present study was to estimate the gestational age of Egyptian goats by B-mode ultrasound measurement of embryonic or fetal parts throughout pregnancy. Trans-rectal (TR) ultrasonography (7 MHz) was carried out on 15 pregnant Egyptian does at Day 10 post mating on alternate days until Day 25 and then once at 3-5-day intervals until Day 50. Trans-abdominal (TA) ultrasonography (3.5-5 MHz) was carried out on the same animals from Days 25 to 130 at 3-5-day intervals. After imaging the embryo or the fetus, the following parameters were measured: length of the embryo or fetus (CRL), heart rate (FHR), biparital diameter (BPD), trunk diameter (TD), placentome size (PS), umbilical cord diameter (UCD) and femur length (FL). The average of days at which the embryonic vesicle was first determined by TR and TA ultrasonography was 16.98+/-1.97 and 27.87+/-3.48, respectively. The embryo proper with a beating heart was first determined by TR and TA ultrasonography at an average of 22.36+/-2.66 and 30.36+/-4.75 days, respectively. All the fetal measures were significantly (P or =90) with the gestational age. In conclusion, the age of embryo or fetus in Egyptian does can be estimated by ultrasound measuring the crown rump length, biparital diameter, trunk diameter, placentome size, umbilical cord diameter and femur length.

  5. Epstein-Barr virus and breast cancer: Epidemiological and Molecular study on Egyptian and Iraqi women

    International Nuclear Information System (INIS)

    Background and purpose: The role of Epstein-Barr virus (EBV) in breast carcinogenesis is still controversial. Unraveling this relationship is potentially important for better understanding of breast cancer etiology, early detection and possibly prevention of breast cancer. The aim of the current study is to unravel the association between EBV and primary invasive breast cancer (PIBC) in two different Arab populations (Egyptian and Iraqi women). Patients and Methods: The study was done on paraffin-embedded tissues of 40 Egyptian and 50 Iraqi patients with PIBC in addition to 20 normal breast tissues as controls for each group. Both controls and neoplastic tissues were assessed for the expression of EBV genes and proteins (EBNA-1, LMP-1, and EBER) as well as CD21 marker by immunohistochemistry (IHC), in situ hybridization (ISH) and PCR techniques. Results: Our gold standard for EBV reactivity in breast cancer cases was positivity of both EBNA1 by PCR and EBER by in situ hybridization. EBV was detected in 18/40 (45%) and 14/50 (28%) of Egyptian and Iraqi women; respectively where p = 0.073, compared to 0/20 (0%) of their control groups (p < 0.05). Regarding the association between EBV positivity and tumor grade, there was not any statistical significant difference between EBV presence and tumor grade in both populations

    This cross-cultural study compared explanations of sleep paralysis (SP) in two countries and two groups with different levels of education in one country. Comparisons were made between individuals having experienced SP at least once in a lifetime from Cairo, Egypt (n = 89), Copenhagen, Denmark (n = 59), and the American University in Cairo, Egypt (n = 44). As hypothesized, participants from the general Egyptian population were more likely to endorse supernatural causal explanation of their SP compared to participants from Denmark; participants from the American University in Cairo were less likely to endorse supernatural causes of their SP compared to participants from the general Egyptian population. Moreover, participants from the American University in Cairo were marginally significantly more likely to endorse supernatural causes of their SP compared to participants from Denmark. Additionally, we explored which culturally bound explanations and beliefs about SP existed in Egypt and Denmark. We found that nearly half (48%) of the participants from the general Egyptian population believed their SP to be caused by the Jinn, a spirit-like creature with roots in Islamic tradition, which constitutes a culturally bound interpretation of the phenomenology of SP in this region of the world. Case studies are presented to illustrate these findings. PMID:24084761

    Full Text Available BackgroundIn recent years, several plant species have been used as bioindicators to evaluate the toxicity of environmental contaminants on vegetal organisms. In this study, Egyptian clover and Sudan grass seedlings were grown in four cadmium (Cd concentration levels (0.0, 25, 50 and 100 µM in MS media to analyze growth responses, Cd accumulation in the shoots and roots of plantlets, proline contents, chlorophylls content and MDA levels of both plantlets. As well as RAPD analysis and leaves ultrastructure were detected.ResultsThe results showed that there was a significant decrease in root and shoot lengths, Chl a, Chl b, total Chl and carotenoids contents for both Egyptian clover and Sudan grass. However, there was a significant increase in Cd accumulation, proline and malondialdehyde (MDA levels. The genetic variation between Egyptian clover and Sudan grass were evaluated using random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR markers to establish specific DNA markers associated with Cd stress. The results of transimssion electron microscopy (TEM showed a clear disorder in the Cd treated Egyptian clover and Sudan grass seedlings.ConclusionIn conclusion, biochemical, molecular and ultrastructure changes in Egyptian clover and Sudan grass could be used as a useful biomarker assay for the detection of genotoxic effects of Cd stress on plants. However, it is necessary to be further confirmed and optimized in the future research.

    Objective: Thalassemia is blood related disease which arises from the reduced level of hemoglobin in red blood cells (RBC), a protein responsible for carrying oxygen inside the body. Considering its widespread occurrence in developing countries like Pakistan, this study aims to investigate the common molecular anomalies of the beta thalassemia disease in district Charsadda, Khyber Pakhtunkhwa. Methods: This work was done at Abdul Wali Khan University (AWKU) Mardan, Khyber Pakhtunkhwa, Pakistan. The work was performed on the blood samples collected from the patients and their families with beta thalassemia major (n = 13 families) belonged to District Charsadda. The collected blood samples were analyzed for presence of six known mutations with the help of polymerase cha in reaction technique i.e. amplification of refractory mutation system. Results: Our Study reports six known mutations (IVS-1-5, FSC 8/9, CD 41/42, IVS-1-1, CD 15 and FSC-5) accounting for about 90% of total beta thalassemia genes in this country. Among the reported mutations, IVS 1-5 was the most prevalent beta thalassemia gene in patients belonging to District Charsadda. Conclusion: The results and findings of the current study may help in accessing the frequency of these common mutations and in initiating pre-natal diagnosis programme in Pakistan. PMID:27182268

  12. Breast cancer laterality among Egyptian patients and its association with treatments and survival

    International Nuclear Information System (INIS)

    Background and aim: Breast cancers (BCs) involve the left side (LS) more than the right side (RS). Among the Egyptians, neither BC laterality nor its association with demographic factors, tumor locations, treatments and outcomes were previously reported. Patients and methods: Laterality was analyzed among 5459 BCs from the Gharbiah population- based cancer registry covering > 5% of the Egyptian population. Cox proportional model was used to assess the independent effect of stage, ER, and laterality on overall survival (OS). Results: In Egypt, BCs involve LS more than RS with LS-to-RS ratio (LRR) of 1.16. LS predominance was evident among men and women and both younger (< 45 years) and older patients. HER2 over-expression and ductal cancers were significantly more in RSBCs while lobular cancers were significantly more in LSBCs. There were no significant differences in localization within the breast between LSBCs and RSBCs (p = 0.51). LS predominance was noticed across all subgroups except in patients with HER2 positive tumors (LRR = 0.63; p = 0.02). OS was significantly better in stage II and ER positive tumors than stage III and ER negative tumors. Despite OS of LSBCs being generally lower than RSBCs, this was not statistically significant. The significant impact of stage on OS was lost in LSBCs. ConclTusions: Among Egyptian patients, the left breast is at greater risk of cancer than the right one. Despite right-sided tumors seemed more aggressive, Left-sided ones tend to confer worse survival than right-sided tumors.

  13. The development of the skull of the Egyptian Cobra Naja h. haje (Squamata: Serpentes: Elapidae.

    Eraqi R Khannoon

    Full Text Available The study of craniofacial development is important in understanding the ontogenetic processes behind morphological diversity. A complete morphological description of the embryonic skull development of the Egyptian cobra, Naja h. haje, is lacking and there has been little comparative discussion of skull development either among elapid snakes or between them and other snakes.We present a description of skull development through a full sequence of developmental stages of the Egyptian cobra, and compare it to other snakes. Associated soft tissues of the head are noted where relevant. The first visible ossification centres are in the supratemporal, prearticular and surangular, with slight ossification visible in parts of the maxilla, prefrontal, and dentary. Epiotic centres of ossification are present in the supraoccipital, and the body of the supraoccipital forms from the tectum posterior not the tectum synoticum. The venom glands are visible as distinct bodies as early at stage 5 and enlarge later to extend from the otic capsule to the maxilla level with the anterior margin of the eye. The gland becomes more prominent shortly before hatching, concomitant with the development of the fangs. The tongue shows incipient forking at stage 5, and becomes fully bifid at stage 6.We present the first detailed staging series of cranial development for the Egyptian cobra, Naja h. haje. This is one of the first studies since the classical works of G. de Beer and W. Parker that provides a detailed description of cranial development in an advanced snake species. It allows us to correct errors and misinterpretations in previous accounts which were based on a small sample of specimens of uncertain age. Our results highlight potentially significant variation in supraoccipital formation among squamates and the need for further research in this area.

  14. Modeling the dependency of radon concentration levels inside ancient Egyptian tombs on the ambient temperature variations

    International Nuclear Information System (INIS)

    Radon concentration inside partially closed places like dwellings, caves and tombs, depends on many parameters. Some parameters are known quantitatively as radon exhalation rate for walls, decay constant, surface to volume ratio and outdoor concentration while other parameters as ventilation rate is in common known qualitatively due to useless of traditional methods (tracer gases) in many places as ancient Egyptian tombs. This work introduces a derived mathematical model to evaluate the sensitivity of radon concentration levels inside single sided opening places as ancient Egyptian tombs on the ambient temperature differences. The obtained formula for the natural ventilation rate depends on the indoor and outdoor temperature difference and the geometrical dimensions of the doorway. The effects of in and out flow mixing, air viscosity, streamline contraction, swirling flow and turbulence, were taken into consideration in terms of an empirical correction factor. According UNSCEAR reports, the exhalation rate Φ=Craλrn fρs(1-ε)L; Cra the effective radium content, λrn decay constant, f emanation fraction, ρs soil grain density, ε porosity and L diffusion length, these are approximately static parameters but the variability of ambient temperature introduces a source of energy of fluctuating strength to radon atoms in rocks which controls the flow rate and the ambient content of radon. Therefore, the change of outdoor and indoor temperature difference causes fluctuation of value and direction of volume flow rate in such places consequently causes the daily variation and on average the seasonal variation of radon concentration. Therefore according to the present model, the daily accurate expectation of radon concentrations inside ancient Egyptian tombs, require precise measurements of indoor and outdoor temperatures

    AIM: To describe the socio-demographic features, eti ology, and risk factors for Budd-Chiari syndrome (BCS) in Egyptian patients.METHODS: Ninety-four Egyptian patients with con firmed primary Budd-Chiari syndrome were presented to the Budd-Chiari Study Group (BCSG) and admitted to the Tropical Medicine Department of Ain Shams University Hospital (Cairo, Egypt). Complete clinical evaluation and laboratory investigations, including a thrombophilia workup and full radiological assessment, were per formed to determine underlying disease etiologies.RESULTS: BCS was chronic in 79.8% of patients, acute or subacute in 19.1%, and fulminant in 1.1%. Factor V Leiden mutation (FVLM) was the most com mon etiological cause of disease (53.1%), followed by mutation of the gene encoding methylene tetra hydrofolate reductase (MTHFR) (51.6%). Current or recent hormonal treatment was documented in 15.5% of females, and BCS associated with pregnancy was present in 17.2% of females. Etiology could not be de termined in 8.5% of patients. Males had significantly higher rates of MTHFR gene mutation and Behget' s disease, and females had significantly higher rates of secondary antiphospholipid antibody syndrome. A highly significant positive relationship was evident between the presence of Behget's disease and inferior vena caval occlusion, either alone or combined with occlusion of the hepatic veins (P < 0.0001).CONCLUSION: FVLM is the most common disease etiology and MTHFR the second most common in Egyptian BCS patients. BCS etiology tends to vary with geographic region.

    2011-01-01

    Egypt's medical tourism industry has been experiencing tremendous growth. However, Egypt continues to lack the necessary investment in its public health system to effectively care for its population. Current policy and the emergence of medical tourism have led to unequal health care access, resulting in high a prevalence of infectious diseases and lack of resources for its most vulnerable populations. As a new Egyptian government emerges, it is important for policymakers to understand the critical issues and ethical concerns of existing health policy. This understanding may be used to propose new policy that more effectively allocates to care for Egypt's population. PMID:22619867

    Khedr, A.; Borgman, H.

    What is the relation between the process of adopting new technologies, and its impact on business value, in situations of high internal and external uncertainty? Whereas technology adoption is generally fairly well understood, the models do not seem to hold in situations of high uncertainty. The aim of this paper is to investigate the impact of this uncertainty, using a case study on the introduction of a new technology in a large Egyptian public bank. After exploring the most relevant uncertainty factors and their impact on the adoption process, the paper ends with a general discussion and conclusion.

  9. Determination of trace elements in Egyptian molasses by instrumental neutron activation analysis

    International Nuclear Information System (INIS)

    Multielement neutron activation analysis was applied to determine macro, micro and trace amounts of Al, Br, Ca, Cl, Co, Cr, Cs, Fe, K, La, Mg, Mn, Na, Rb, Sc and V in molasses of Egyptian cane sugar factories. The threshold element concentrations are acceptable and below the safety. Differences in element concentrations may be related to different botanic textures and structures, different compositions of sugar cane plants, corrosion of containers or changes in soil as a result of geochemical differentiation. The method is sensitive down to 0.038 ppm of V. The relative errors due to counting statistics are in the range of 0.2-11%. (author) 17 refs

    An Eighteenth Dynasty Egyptian sealed pottery stored at the Museum of Aquitaine (Bordeaux, France) has been investigated using terahertz radiation, X-rays and neutrons. THz computed tomography revealed nondestructively the presence of content, whereas X-rays and neutrons analyzed more precisely the fabrication process and conservation of the pottery together with the nature of this content owing to higher spatial resolution and contrast. With neutron tomography, we determined the method used to seal the jar as well as the finer structure of the inner content. Neutron-induced prompt gamma spectroscopy was finally applied to measure the elemental composition of the content, which is supposed to consist of dried germinated seeds.

    Comparisons are made between ancient ritual uses of the flowers of Nymphaea (Nymphaeaceae) in Maya and Egyptian civilizations. Recurrent motifs encountered in the art of both of these ancient civilizations suggests that the role fo the water lily was that of a narcotic (psychodysleptic) used to mediate ecstasis among a priestly caste. Relevant literature is reviewed as are chemical data. Elements in the complex belief systems of these two civilizations need to be reinterpreted in view of the use of two water lilies as ritual narcotics. The species implicated are Nymphaea caerulea Sav., in Egypt, and N. ampla DC., among the Maya. PMID:7007741

  14. Women Health Outreach Program; a New Experience for all Egyptian Women

    International Nuclear Information System (INIS)

    The global health community faces a challenge with breast cancer being the most common cause of cancer related death among women around the globe. Since breast cancer’s pathogenesis is poorly understood, primary prevention is still a distant goal. Thus secondary prevention through early detection is the only feasible approach at present. With this strong conviction, the launching o f the first Egyptian national screening program Women Health Outreach Program(WHOP), was announced on October 30 th 2007. This project is a government- funded program that offers free breast screening for all Egyptian women above the age of 45 years. In addition to free mammograms, the program gives the participants a chance to be screened for diabetes, hypertension and obesity as well. Positively detected cases are also offered the option of free management. During the period from October 30 th , 2007, up to February 9 th , 2009, 20, 098 women in Cairo, Alexandria and Suez governorates were screened for breast cancer, diabetes, hypertension and obesity through the program. In this article we will represent the achievements, challenges and services delivered by WHOP

  15. Natural radioactivity in Egyptian and industrially used australian bauxites and its tailing red mud

    International Nuclear Information System (INIS)

    Red mud is produced in considerable masses as a waste product in the production of aluminum from bauxite. It may be used for industrial or agricultural purposes. According to it's genesis by weathering and sedimentation bauxites contain high concentrations of uranium and thorium. Three Egyptian bauxites, Australian industry used bauxite and its red mud tailing were analyzed by a high resolution gamma spectrometer, with a hyper pure germanium detector. The three Egyptian bauxites show high concentrations in uranium series, and around 120 Bq kg-1 for uranium -235. K-40 concentrations for these samples ranged from 289 to 575 Bq kg-1. Thorium series concentrations show lower values. The industrially used bauxite shows very low concentrations for all radioactive nuclides. Its tailing red mud as a low level radioactive waste LLRW, shows low concentrations for uranium - series, thorium - series and also 40K, so it is recommended to be used in industrial and agricultural purposes, which is not permissible for the normal red mud.

  16. Multiple Patterns of FHIT Gene Homozygous Deletion in Egyptian Breast Cancer Patients

    International Nuclear Information System (INIS)

    Fragile histidine triad (FHIT) gene encodes a putative tumour suppressor protein. Loss of Fhit protein in cancer is attributed to different genetic alterations that affect the FHIT gene structure. In this study, we investigated the pattern of homozygous deletion that target the FHIT gene exons 3 to 9 genomic structure in Egyptian breast cancer patients. We have found that 65% (40 out of 62) of the cases exhibited homozygous deletion in at least one FHIT exon. The incidence of homozygous deletion was not associated with patients clinico pathological parameters including patients age, tumour grade, tumour type, and lymph node involvement. Using correlation analysis, we have observed a strong correlation between homozygous deletions of exon 3 and exon 4 (P<0.0001). Deletions in exon 5 were positively correlated with deletions in exon 7 (P<0.0001), Exon 8 (P<0.027), and exon 9 (P=0.04). Additionally, a strong correlation was observed between exons 8 and exon 9 (P<0.0001).We conclude that FHIT gene exons are homozygously deleted at high frequency in Egyptian women population diagnosed with breast cancer. Three different patterns of homozygous deletion were observed in this population indicating different mechanisms of targeting FHIT gene genomic structure.

    The Egyptian Western Desert lies on an important geographic intersection between Africa and Asia. Genetic diversity of this region has been shaped, in part, by climatic changes in the Late Pleistocene and Holocene epochs marked by oscillating humid and arid periods. We present here a whole genome analysis of mitochondrial DNA (mtDNA) and high-resolution molecular analysis of nonrecombining Y-chromosomal (NRY) gene pools of a demographically small but autochthonous population from the Egyptian Western Desert oasis el-Hayez. Notwithstanding signs of expected genetic drift, we still found clear genetic evidence of a strong Near Eastern input that can be dated into the Neolithic. This is revealed by high frequencies and high internal variability of several mtDNA lineages from haplogroup T. The whole genome sequencing strategy and molecular dating allowed us to detect the accumulation of local mtDNA diversity to 5,138 +/- 3,633 YBP. Similarly, theY-chromosome gene pool reveals high frequencies of the Near Eastern J1 and the North African E1b1b1b lineages, both generally known to have expanded within North Africa during the Neolithic. These results provide another piece of evidence of the relatively young population history of North Africa. PMID:19425100

    Genetics polymorphism of the renin-angiotensin system (RAS) affects the pathogenesis of atherosclerosis and associated with coronary artery disease (CAD). We aimed to investigate the association between the RAS genes and premature CAD (PCAD) in Egyptians. 116 patients with PCAD, 114 patients with late onset CAD and 119 controls were included in the study. Angiotensin converting enzyme (ACE), angiotensin II receptor type 1 (ATR1) and angiotensinogen (AGT) genes polymorphisms were analyzed by polymerase chain reaction (PCR). We found that ACE DD, AGT TT and ATR1 CC increased the risk of PCAD by 2.7, 2.8 and 2.86 respectively). Smoking, hypertension, diabetes, total cholesterol, triglycerides and LDL cholesterol were independent risk factors for the development of PCAD. We conclude that the ACE DD, AGT TT and ATR1 CC genotypes may increase the susceptibility of an individual to have PCAD. The coexistence of CAD risk factors with these risky RAS genotypes may lead to the development of PCAD in Egyptian patients. PMID:22387727

    The application of combined Raman spectroscopic and GC-MS analytical techniques for the characterisation of organic varnish residues from Egyptian Dynastic funerary sarcophagal and cartonnage fragments from the Graeco-Roman period, ca. 2200 BP, is described. The nondestructive use of Raman spectroscopy was initially employed to derive information about the specific location of organic material on the specimens, which were then targeted in specific areas using minimal sampling for GC-MS analysis. In the case of the sarcophagal fragment, a degraded yellow-brown surface treatment was identified as a Pistacia spp. resin; this provides additional evidence for the use of this resin, which has previously been identified in Canaanite transport amphorae, varnishes and "incense" bowls in an Egyptian Late Bronze Age archaeological context. The cartonnage fragment also contained an organic coating for which the Raman spectrum indicated a degradation that was too severe to facilitate identification, but the GC-MS data revealed that it was composed of a complex mixture of fatty acid residues. The combined use of GC-MS and Raman spectroscopy for the characterisation of organic materials in an archaeological context is advocated for minimisation of sampling and restriction to specifically identified targets for museum archival specimens.

    This study aimed to report penile dimensions in adult Egyptian males consulting for small-sized penis (SSP) and describe their demographics and andrological profile. A case control study was designed through retrospective data analysis of patients (n = 239) seeking advice for SSP and a control group (n = 59). This included sociodemographics, other andrological complaints, and penile dimensions (pendulous length [PL], penopubic or total length [TL], and circumference [CF]) at flaccid and erect states and the size of the prepubic fatty pad. The results reported that most patients were single, students, and smokers and had not completed a university education. Several patients reported falsely premature ejaculation (PE), penile curvature (PC), and small-sized testes. Most penile dimensions of the patients (mean, cm) were significantly lower than those of the controls, whether in flaccid (PL: 7.4 vs. 8.05, p = .008; CF: 8.7 vs. 8.98, p = .026) or erect state (PL: 11.8 vs. 13, p = .000; TL: 14.2 vs. 15, p = .000; CF: 11.3 vs. 11.8, p = .003). However, no patient presented with a pendulous penile length <4 cm in flaccid or <7 cm in erect state. In conclusion, Egyptian men consulting for SSP did not have true small organs, but their penile dimensions were slightly smaller than those of men without such complaint. The proper sexual education program is highly advisable in these situations to avoid the myths and misconceptions about sexuality.

    2016-01-01

    Full Text Available Recent studies in different parts of the world have highlighted that phrasal verbs constitute a learning difficulty for English language learners despite their confirmed significance and high productivity in English. Proposed explanations include cross-linguistic differences, the complex nature of phrasal verbs, low language proficiency and psychological factors. The present study examines this difficulty among an Arabic-speaking population of Egyptian undergraduates in a foreign language context. To this end, a total of 407 Egyptian undergraduates in a private English-medium university completed a paraphrase task, two gap-filling tasks and a survey. The results confirm the difficulty highlighted in earlier studies, particularly at the production level. The results also show that the under-representation of phrasal verbs in the participants’ production can be interpreted in terms of cross-linguistic differences, passive learning for comprehension and limited language exposure. The study thus supports a multi-faceted model for the explanation of the limited use of phrasal verbs by English language learners, and calls for a revision of the English language teaching programs in Egypt. Keywords: phrasal verbs, lexical knowledge, avoidance, vocabulary studies, contrastive linguistics

  6. Developing an interactive computational system to simulate radon concentration inside ancient egyptian tombs

    International Nuclear Information System (INIS)

    RSSP (Radon Scale Software Package) is an interactive support system that simulates the radon concentration inside ancient Egyptian tombs and the consequences on the population in terms of internal and external exposure. RSSP consists of three interconnected modules: the first one simulates the radon concentration inside ancient Egyptian tombs using a developed mathematical model. This model introduces the possibility of controlling the rate of radon accumulation via additional artificial ventilation systems. The source of inputs is an editable database for the tombs includes the geometrical dimensions and some environmental parameters like temperature and outdoor radon concentration at the tombs locations. The second module simulates the absorbed dose due to internal exposure of radon and its progeny. The third module simulates the absorbed dose due to external exposure of Gamma rays emitted from the tomb wall rocks. RSSP introduces the facility of following the progress of radon concentration as well as Internal and external absorbed dose in a wide range of time (seconds, minutes, hours and days) via numerical data and the corresponding graphical interface

  7. Analysis of oxidative stress status, catalase and catechol-O-methyltransferase polymorphisms in Egyptian vitiligo patients.

    Dina A Mehaney

    Full Text Available Vitiligo is the most common depigmentation disorder of the skin. Oxidative stress is implicated as one of the probable events involved in vitiligo pathogenesis possibly contributing to melanocyte destruction. Evidence indicates that certain genes including those involved in oxidative stress and melanin synthesis are crucial for development of vitiligo. This study evaluates the oxidative stress status, the role of catalase (CAT and catechol-O-Methyltransferase (COMT gene polymorphisms in the etiology of generalized vitiligo in Egyptians. Total antioxidant capacity (TAC and malondialdehyde (MDA levels as well as CAT exon 9 T/C and COMT 158 G/A polymorphisms were determined in 89 patients and 90 age and sex-matched controls. Our results showed significantly lower TAC along with higher MDA levels in vitiligo patients compared with controls. Meanwhile, genotype and allele distributions of CAT and COMT polymorphisms in cases were not significantly different from those of controls. Moreover, we found no association between both polymorphisms and vitiligo susceptibility. In conclusion, the enhanced oxidative stress with the lack of association between CAT and COMT polymorphisms and susceptibility to vitiligo in our patients suggest that mutations in other genes related to the oxidative pathway might contribute to the etiology of generalized vitiligo in Egyptian population.

    Full Text Available Abstract Introduction Ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome (OMIM No. 129900 is characterized by the triad of ectrodactyly, ectodermal dysplasia and facial clefting (of the lip and/or palate. Holoprosencephaly denotes a failure in the division of the embryonic forebrain (prosencephalon into distinct lateral cerebral hemisphere. The association between ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome and holoprosencephaly is very rare. Here we report holoprosencephaly in an Egyptian infant with ectrodactyly-ectodermal dysplasia-cleft lip or palate syndrome. Case presentation An 11-month-old Egyptian female baby was referred to our institution for an evaluation of poor growth; the pregnancy and perinatal history were uneventful. On examination, her growth parameters were below the third centile, she had bilateral ectrodactyly of both hands and feet, dry rough skin, sparse hair of the scalp and operated right cleft lip and cleft palate. Computerized tomography of her brain revealed holoprosencephaly. Conclusion The importance of the early diagnosis of this syndrome should be emphasized in order to implement a multidisciplinary approach for proper management of such cases.

    Full Text Available Inhibitors of tumor growth using extracts from aromatic plants are rapidly emerging as important new drug candidates for cancer therapy. The cytotoxicity and in vitro anticancer evaluation of the essential oils from thyme, juniper and clove has been assessed against five different human cancer cell lines (liver HepG2, breast MCF-7, prostate PC3, colon HCT116 and lung A549. A GC/MS analysis revealed that α-pinene, thymol and eugenol are the major components of Egyptian juniper, thyme and clove oils with concentrations of 31.19%, 79.15% and 82.71%, respectively. Strong antioxidant profiles of all the oils are revealed in vitro by DPPH and β-carotene bleaching assays. The results showed that clove oil was similarly potent to the reference drug, doxorubicin in prostate, colon and lung cell lines. Thyme oil was more effective than the doxorubicin in breast and lung cell lines while juniper oil was more effective than the doxorubicin in all the tested cancer cell lines except prostate cancer. In conclusion, the essential oils from Egyptian aromatic plants can be used as good candidates for novel therapeutic strategies for cancer as they possess significant anticancer activity.Los inhibidores de crecimiento de tumores usando extractos de plantas aromáticas están emergiendo con rapidez como nuevos e importantes medicamentos para el tratamiento del cáncer.

    2013-07-01

    Presented are the research objectives of the project "Irep en Kemet", Wine of Ancient Egypt, and the content of the project's website. This research aims at documenting the complete corpus of wine in ancient Egypt and analysing the data (iconography, textual sources and artefacts) to unveil the importance of the ancient Egyptian wine culture legacy in the Mediterranean region. At this stage, a bibliographical researchable database relevant to wine, viticulture and winemaking in the ancient Egypt has been completed, with 197 entries including articles, books, chapters in book, academic thesis (PhD and MA), essay, abstracts, on-line articles and websites. Moreover, a scene-detail database for the viticulture and winemaking scenes in the Egyptian private tombs has been recorded with 97 entries, some of them unpublished, and the collected data is under study. The titles of the tombs' owners and the texts related to the scenes will be also recorded. A photographic survey of the graves containing images related with viticulture and winemaking will be carried out in order to have the most accurate information on the location and stage of conservation of those images. Our main goal is to provide scholars with a complete, comprehensive archaeological and bibliographical database for the scenes of viticulture and winemaking depicted in the Egyptian private tombs throughout the ancient Egyptian history. The project's website (http://www.wineofancientegypt.com) will include all the collected data, the study and analysis, the project's history and team members, publications as well as the results of our research.

The Egyptian vulture, a diurnal, scavenging, rupicolous bird of prey, is one of four vulture species that currently inhabit the Iberian Peninsula. An analysis of the remains found in the nests confirms that it has a heterogeneous diet that includes remains from human activities (butchery and food production) and the...

  20. Experimental and theoretical investigation of diffuse solar radiation: Data and models quality tested for Egyptian sites

    International Nuclear Information System (INIS)

    In order to obtain reliable irradiation data for the design, operation and economic assessment of solar power stations, eight widely used standard models predicting diffuse irradiation values are tested. A statistical analysis of hourly, daily and monthly correlations is carried out, using a 5 yr data archive (1999-2003) of hourly global and diffuse solar irradiances obtained at five selected meteorological stations over greater Egypt area. The accuracy of the candidate correlations are performed in terms of the two widely used statistical indicators, mean bias and root mean square errors; standard deviation, standard error and F-test, were also introduced. The results indicate that the correlations relating the diffuse fraction (K D) with both clearness index (K T) and the sunshine fraction (S/S O) are more reliable for diffuse irradiation predictions in the Egyptian environment than using each variable separately

    2008-01-01

    This study explored knowledge, attitudes and practices towards HIV/AIDS infection among 1256 Egyptian industrial and tourism workers aged 16-40 years. Compared with industrial workers, tourism workers had a significantly better perception of the magnitude of the HIV/AIDS problem worldwide as well as in Egypt and of the likelihood of the problem worsening. Knowledge of tourism workers was also significantly better about causative agent of AIDS and methods of transmission. Both groups had negative attitudes towards patients living with HIV/AIDS concerning their right to confidentiality and to work. Both groups had a positive attitude towards behaviour change for protection from HIV/AIDS, principally via avoidance of extramarital sexual relations and adherence to religious beliefs. Use of condoms as a way to avoid HIV/AIDS was reported by only 0.4% of workers. PMID:19161085

    Orf virus was clinically diagnosed from different field cases of sheep and goat in Hawamdia, Giza, Egypt during the summer 2006. Skin scabs were collected and used for virus isolation, electron microscopy, PCR and sequencing for confirmation, and differential diagnosis. The aetiological virus was fruitfully isolated on the chorio-allantoic membrane of SPF embryonated chicken eggs indicated by expressing the characteristic pock lesions of Poxviridae family. Electron microscopy examination exposed negatively stained oval-shape virus particles trait for members of the genus Parapoxvirus. A 392 bp fragment of the late transcription factor (VLTF-1) gene of orf virus was amplified by PCR from the DNA extracted from the isolates. Phylogenetic analysis revealed 99% identity with other orf virus strains reported worldwide. Selection and processing of clinical specimens and PCR assay applied in this endeavor, presented a reliable laboratory diagnostic tool for orf infections and first molecular characterization of Egyptian orf isolates.

    Our objective was to determine age-specific rubella susceptibility among Egyptian females. This was a cross-sectional survey in eight randomly selected communities, with the largest number of reported rubella cases in the 2007 Rubella surveillance. A sample of 5672 females between the ages of 6 and 45 years were interviewed. Of those 602 blood samples were obtained and tested for rubella IgG. The proportion of seronegative females was 9.7%. The highest proportion of susceptible females was in the ages between 6 and 25 years and the highest risk of susceptibility was among unmarried females [odds ratio (OR)=7.2]. The knowledge of interviewed females about rubella, the vaccine and the effect rubella infection on pregnancy and on the fetus was very limited. In conclusion more vaccination coverage is needed, with simultaneous increase of public awareness to minimize the susceptible female population. PMID:20800112

    2006-04-01

    We describe here an ancient case of cysticercosis that was discovered in an Egyptian mummy of a young woman of about 20 years of age who lived in the late Ptolemaic period (second to first centuries b.c.). On removal of the stomach and its rehydration, a cystic lesion in the stomach wall was observed by naked eye. Microscopical examination of sections of this lesion revealed a cystic structure, with a wall, with numerous projecting eversions, a characteristic feature of the larval stage (cysticercus) of the human tapeworm Taenia solium (or "pig tapeworm"). Immunohistochemical testing with serum from a T. solium-infected human confirmed the identity of the cyst. This finding is the oldest on record of the antiquity of this zoonotic parasite. This observation also confirms that, in Hellenistic Egypt, the farming of swine, along with man an intermediate host of this parasite, was present, and supports other archeological evidence.

    Full Text Available Due to the environmental pressures on organizations, the demand on Business Process Management (BPM automation suites has increased. This led to the arising need for managing process-related risks. Therefore the management of risks in business processes has been the subject of many researches during the past few years. However, most of these researches focused mainly on one or two stages of the BPM life cycle and introduced a support for it. This paper aims to provide a reference model for Risk-Aware BPM which addresses the whole stages of the BPM life cycle, as well as some current techniques are listed for the implementation of this model. Additionally, a case study for a business process in an Egyptian university is introduced, in order to apply this model in real-world environment. The results will be analyzed and concluded.

  7. Response of irradiated Egyptian clover (Trifolium alexandrinum L.) to water stress

    International Nuclear Information System (INIS)

    Egyptian clover (Trifolium alexandrinum L.) is one of the main leguminous forage crops in Egypt. Gamma rays represent one of the important physical activators for growth and productivity. The seed were irradiated using three doses of gamma radiation (100,200 and 300 Gy) and two levels of irrigation (10 and 20 days) after germination. Gamma radiation treatments stimulated growth criteria in normal irrigation treatment, while drought irrigation treatment stunted these criteria. The most significant dose was 100 Gy, which stimulated growth criteria, chlorophylls a , b, total chlorophyll and carotenoids in both irrigation treatments used and growth hormones under drought condition. Drought stress and gamma irradiation increase amino acid content and caused change in band concentration of esterase and peroxidase isozyme .Also, 13 protein bands appeared only in treated plant with 100 Gy under drought condition. It could be concluded that the low dose (100 Gy) of gamma irradiation release the effect of drought stress.

    Computer tomography has been used to image and reconstruct in 3-D an Egyptian mummy from the collection of the British Museum. This study of Tjentmutengebtiu, a priestess from the 22nd dynasty (945-715 BC) revealed invaluable information of a scientific, Egyptological and palaeopathological nature without mutilation and destruction of the painted cartonnage case or linen wrappings. Precise details on the removal of the brain through the nasal cavity and the viscera from the abdominal cavity were obtained. The nature and composition of the false eyes were investigated. The detailed analysis of the teeth provided a much closer approximation of age at death. The identification of materials used for the various amulets including that of the figures placed in the viscera was graphically demonstrated using this technique.

  9. [The effects of manpower emigration on income distribution and consumption models in the Egyptian economy].

    1985-01-01

    This work analyzes the effects of emigration from Egypt on the distribution of income and the consumption model of the Egyptian economy. The increasing role of remittances as a principal source of household income has disturbed the old division of income among socioeconomic groups. It is difficult to estimate the volume of remittances with any precision because of the variety of ways in which they can be made. Official statistics tend to underestimate their value by ignoring black market transactions, remittances of merchandise, and other forms. An estimate was made of the value of remittances in 1980 taking account of wage levels of 5 different types of workers in the principal employing countries, their average propensities to save, and the employment structure of migrants by socioprofessional groups. The average educational level of emigrants appears to have declined somewhat between 1972-78. Average monthly income for emigrants was estimated to range from 792 Egyptian pounds for technical and professional workers to 252 for unskilled workers and the propensity to save was estimated to range from 40% for technical and scientific workers to 15% for unskilled workers. The total income remitted in 1980 in millions of Egyptian pounds was estimated at 912 for 240,000 technical and scienfific workers, 739 for 360,000 intermediate level workers, 415 for 300,000 artisans and workers, 60 for 60,000 chauffeurs, and 109 for 240,000 unskilled workers. Although remittances have elevated the per capita income of the low income groups, their impact has been diminished by severe inflationary pressures which have led to a decline in living levels and a less complete satisfaction of basic needs. Salary levels of construction workers were 7-9 times higher in Egyptian pounds in 1977 in 3 countries of immigration than in Egypt, while they were 7-10 times higher in 4 countries for university professors. Remittances are used by families receiving them for subsistence or investment

  11. The effect of environmental factors on breast lumps of Egyptian women in different socioeconomic levels

    International Nuclear Information System (INIS)

    The environmental risk factors related to the breast tumors (lumps) are essential in order to build strategies to decrease cancer incidence and mortality among different socioeconomic and cultural backgrounds. A case control study of 70 cases and 52 controls were classified into high, middle and low socioeconomic classes. The results revealed significant increased risk of breast tumors among working females, having positive family history, married with lower mean parity, with higher consumption of fatty meals, lesser meat intake. Non significant risk factors were the social class, exposure to ionizing radiation, non lactating. wearing tight bra, consumption of vegetables and fruits, oral contraceptive pill users and exposure to outdoor air pollution or indoor pollution as floors and wall paintings. In conclusion, this study highlights the positive life style for egyptian women so they can prevent some of the environmental risks of breast tumors. Increasing the awareness of breast diseases and regular examination remains the corner stone for early detection management of breast lumps.

    School nurses play a vital role in the promotion of sexual health. However, there is very limited evidence of how school nurses experience this topic in an Islamic cultural setting. Using an exploratory qualitative design, 13 in-depth interviews were conducted with Egyptian school nurses. Data were subject to thematic analysis. Four themes emerged from this analysis, "personal issues," "cultural and political dimensions," "parental issues," and "skills and confidence." These themes represented how nurses' views on sex education were tempered by personal and social forces--affecting their practice. Fear of being blamed for creating a permissive culture was a feature of nurses' concerns in this culture. The belief that sex education is morally challenging affected nurses and must be addressed to enable effective sex education to take place. School nurses must contribute actively to this debate and receive governmental support. PMID:24106180

  13. Regulatory inspection of the egyptian gamma irradiator using a proposed inspection checklist

    International Nuclear Information System (INIS)

    Regulatory inspections are one of the most important elements of a regulatory programme. It shall be performed in all areas of the regulatory responsibility and during all phases of siting, design, construction, commissioning, operation, maintenance and decommissioning of an irradiator facility. The egyptian mega gamma irradiator operating since december 1979 has a Co-60 source of about 400 kilo curies and is used mainly for sterilization of medical supplies and pharmaceuticals and for preservation of some food stuffs. The constructor (Nordion international Inc.) recommended an extensive inspection programme. In accordance with the international and national (2.3) regulations as well as the licensing conditions, the competent authority (NCNSRC) shall perform regulatory inspections both announced and unannounced. In order to facilitate the inspection task and to harmonize the inspection reports a checklist for inspection is proposed which can be used also as an inspection report form

    Background: Most studies of stress and food choice found that individuals experiencing periods of stress over-ate food items they would customarily avoid, and that they ate these foods to feel better. This study examined perceived stress and food intake behavior of undergraduate university students...... in Egypt. We assessed students’ levels of stress and correlated it with their consumption of a range of food groups. Methods: The cross sectional study was conducted among undergraduates in Egypt (N=3.271: response rate: 90%). The questionnaire contained a short food frequency questionnaire (FFQ...... vegetables score) than with others (sweet, cookies and snacks score). Increased perceived stress was associated with decreased food intake, and the association was more pronounced in males than in females, suggesting that this sample of Egyptian students ate less across all the food groups we examined when...

    2015-12-01

    Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces were obtained. Artificial infection of Puccinia striiformis was performed under greenhouse conditions during two growing seasons and relative resistance index (RRI) was calculated. Two Egyptian bread wheat cultivars i.e. Giza-168 (resistant) and Sakha-69 (susceptible) were also evaluated. RRI values of two-year trial showed that 10 RILs responded with RRI value >6 2 yellow rust. However, further molecular analyses would be performed to confirm markers associated with the resistance and suitable for marker-assisted selection. Resistant RILs identified in the study could be efficiently used to improve the resistance to yellow rust in wheat.

    The nature, function, and anatomy of the heart have been extensively studied since 3500 B.C. Greek and Egyptian science developed a basic understanding of the heart, although this was primarily related to religious beliefs. During the Hippocratic era, Hippocrates and his colleagues developed a more scientific and less religious understanding of the cardiovascular system. The post-Hippocratic era was characterized by more advanced descriptions of the location, structure, and function of the heart. The Alexandrian, Roman, Medieval Islamic, and European eras included turning points in the history of cardiac anatomy. Subsequently, after the structure and function of the heart were established, its connection with the lungs was investigated. Description of the pulmonary circulation was followed by the discovery of the conductive system and innervation of the heart. PMID:26918296

    In Egypt, there is a paucity of biomarker data on aflatoxin (AF) exposure. The study assessed the level and frequency of breast milk AFM1 as a biomarker of maternal exposure. Breast milk samples were collected from a selected group of 388 Egyptian lactating mothers of children attending the New El-Qalyub Hospital, Qalyubiyah governorate, Egypt, during May-September 2003. Following aflatoxin extraction, AFM1 levels were assessed by high-performance liquid chromatography (HPLC) with fluorescence detection. Approximately 36% of mothers tested positive for AFM1 (median 13.5 pg ml-1, interquartile range (IQR) 10.27-21.43). Non-working status (p = 0.018, odds ratio (OR) = 2.87), obesity (p = 0.004, OR = 3.01), high corn oil consumption (p = 0.002, OR = 2.21), number of children (>1) (p = 0.025, OR = 1.99), and early lactation stage (effect.

  19. External and internal exposure to natural radiations inside ancient Egyptian tombs in Saqqara

    International Nuclear Information System (INIS)

    Some ancient Egyptian tombs in Saqqara are closed for visit to undergo fixation processes. The workers inside these tombs exposed to natural radiations from natural Gamma emitters (external exposure) and inhale unknown radon doses (internal exposure) for long periods. The external exposure in all studied tombs is lower than the maximum recommended action level. The internal exposure in terms of annual effective dose in the south tomb is equal to 28.83mSv/year which highly exceed the recommended level (3-10mSv/year). In this tomb, the external exposure is equal to 21.43μSv/year. This reflects the hazards of radon over the other natural radiations in the closed area. Among the workers inside the studied tombs, the expected morality is equal to 0.0033%, 0.0199% and 0.0724% for the south entrance of Zoser pyramid, the Serapeum tomb, and the south tomb respectively. ctively

  20. Annual dose measurements and TL-dating of ancient Egyptian pottery

    International Nuclear Information System (INIS)

    In the course of the dating of ancient Egyptian pottery, pottery sherds were collected from three archaeological tombs in Nazlet El Samman region, Giza zone (Egypt). The annual dose from natural background was measured by gamma spectrosocopic technique as well as thermoluminescence (TL) measurements. The results of both methods are in good agreement with a consistency of 99.69%. The extracted quartz exhibited TL dating peaks at about (305 ± 5)oC. The TL dating shows an age of 4301 ± 100 years for the examined pottery which belongs to the ''Fourth Dynasty'' in the ''OlKingdom'' . The uncertainties in TL dating using the additive method are much lower than that of archaeologists. (author)

    A number of organic natural dyestuffs used in dyeing in ancient times, i.e. indigo, madder, turmeric, henna, cochineal, saffron and safflower, have been used to colour Egyptian fabrics based on linen. Their physicochemical properties have been evaluated on thermally aged linen samples. The aged dyed linen samples were thoroughly examined by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD) and tensile strength and elongation measurements. It was found that, in the molecular level, dyes interact mainly with the cellulose compounds of the aged linen while in the macroscopic level tensile and elongation parameters are altered. Tensile strength is positively related to the dye treatment while elongation depends specifically on the type of the dye used. Results converge that the dyed textiles did indeed play a role as protecting agents affecting strength and reducing thermal deterioration.

    Full Text Available The paper tries to assess the role the military plays in revolutions. The first part of the study focuses on the manner in which the competing theories of revolutions try to explain and accommodate the military’s participation in revolutions, attempting to show that the limits of these theoretical enterprises call for a renewed research into the subject at hand. The second part of the paper tries to build a conceptual model, starting from the hypotheses of Charles Tilly, Samuel Huntington and Mehran Kamrava, tested on two particular cases – that of the 1958 Egyptian Revolution and that of the 1958 Iraqi Revolution that can better account for the military’s participation in revolutions and explain when does the military become a revolutionary force and what are the characteristics of revolutions in which the military plays a key-role.

  3. The Representation of Women in Street Songs: A Critical Discourse Analysis of Egyptian Mahraganat

    2015-10-01

    Full Text Available The study investigates the representation of male and female gender identities in Egyptian street songs called Mahraganat. The study discusses the issue with reference to two common songs spreading among young commoners. Since the songs are written by writers who descend from low-standard social group, the analysis exhibits both cultural and societal notions related to how males and females are portrayed in such kind of music. This study attempts to describe how males describe their social group in comparison to the social group to which the women belong. It, thus, constructs the social identity of males and females through the lyrics of this new genre of music.  The findings from such an analysis answer the question about such genre within its social context and the ideologies by which it is dominated reflecting the discursive construction representation of gender and sexual identity.Keywords: gender, identity construction, genre, ideologies

    Full Text Available The study explores gender differences and the role of the ideological background in portraying the roles of the males and the females. Socio-economic statuses affect the description of gender differences and this is proclaimed within the analysis of a recent phenomenon of poor quality street songs. The study represents a detailed description of male and female relationship, so as to spot the light on the literary and societal implications of this newly propagated genre. The study analyses two common songs spreading among commoners distorting the woman’s image predefined in the Egyptian culture. Negative cultural and societal conceptions are explicitly mentioned about the relation between males and females.Keywords: gender, media representation, discourse analysis

    Full Text Available The purpose of this paper is to evaluate the behavior of monetary authorities in Tunisia and Egypt, in response to changes in macroeconomic variables over time based on LSTR model. In this sense, we estimate Taylor-type equations for short-term interest rate in Tunisia and Egypt using quarterly data covering the period 1998.Q4–2013.Q2. We find strong evidence that the real decision-making process followed by these central banks varies from one central bank to another and that it exhibits nonlinear patterns that better capture special events and unexpected contingencies i.e., the terrorist attack in the US in September 2001, the global financial crisis in 2008, and the effect of political instability with the onset of the revolution. Additionally, the presence of asymmetries in the reaction function of the Tunisian and Egyptian Bank requires disconnection from their automatic pilot rules and use of judgement to make decisions.

    Some ancient Egyptian tombs in Saqqara are closed for visit to undergo fixation processes. The workers inside these tombs exposed to natural radiations from natural Gamma emitters (external exposure) and inhale unknown radon doses (internal exposure) for long periods. The external exposure in all studied tombs is lower than the maximum recommended action level. The internal exposure in terms of annual effective dose in the south tomb is equal to 28.83mSv/year which highly exceed the recommended level (3-10mSv/year). In this tomb, the external exposure is equal to 21.43{mu}Sv/year. This reflects the hazards of radon over the other natural radiations in the closed area. Among the workers inside the studied tombs, the expected morality is equal to 0.0033%, 0.0199% and 0.0724% for the south entrance of Zoser pyramid, the Serapeum tomb, and the south tomb respectively. ctively.

    Full Text Available Abstract Background Autism is a biological disorder with clearly defined phenomenology. Studies from the Middle East on this topic have been particularly rare. Little is known about the influence of culture on clinical features, presentations and management of autism. The current study was done to compare characteristics of autism in two groups of Egyptian as well as Saudi children. Methods The sample included 48 children with Autism Spectrum Disorder. They were recruited from the Okasha Institute of Psychiatry, Ain Shams University, Cairo, Egypt and Al-Amal Complex for Mental Health, Dammam, Kingdom of Saudi Arabia. They were grouped into an Egyptian group (n = 20 and a Saudi group (n = 28. They were assessed both clinically and psychometrically using the GARS, the Vineland adaptive behavioral scale, and the Stanford Binnet IQ test. Results Typical autism was more prevalent than atypical autism in both groups. There were no statistically significant differences in clinical variables like regression, hyperactivity, epilepsy or mental retardation. Delayed language development was significantly higher in the Egyptian group while delay in all developmental milestones was more significant in the Saudi group. The Vineland communication subscale showed more significant severe and profound communication defects in the Saudi group while the Gilliam developmental subscale showed significantly more average scores in the Egyptian group. Both groups differed significantly such that the age of noticing abnormality was younger in the Saudi group. The age at diagnosis and at the commencement of intervention was lower in the Egyptian group. The Saudi group showed a higher percentage of missing examinations, older birth order and significantly higher preference to drug treatment, while the Egyptian group showed a high preference to behavioral and phoniatric therapies, higher paternal and maternal education, higher employment among parents and higher family

    The objective of this study was to investigate the pharmacokinetics of marbofloxacin (MAR) following intravenous (iv) and intramuscular (im) administration of a 2.0 mg/kg body weight dosage to five healthy Egyptian buffalo steers. A cross-over design was used with a washout period of 2 weeks. Blood samples were obtained at 0, 5,10,15, and 20 min and at 0.5,0.75,1,2,4,6,8,10,12,24,30 and 48 hours after marbofloxacin administration. The serum marbofloxacin concentrations were quantitated using a modified agar diffusion bioassay method. Marbofloxacin exhibited a relatively high volume of distribution at steady-state (Vdss = 1.77 Lkg), which suggests good tissue penetration, and a total body clearance (Cltot) of 0.18 L/kgxh,which is associated with a long elimination half-life (tl/2beta = 7.52 h). Marbofloxacin was rapidly absorbed at a dosage of 2.0 mg/kg after im administration with an observed maximum serum concentration (Cmax) value of 2.004 microg/mL obtained at a time to peak concentration (tmax) of 0.5 h, and an absolute bioavailability (F %) of 86.79 +/- 5.53 %. The protein-binding ranged from 22 to 24.6 % with an average of 23.4 %. In conclusion, single iv and im administered doses of marbofloxacin were well tolerated by Egyptian buffalo steers. A dosage of 2 mg/kg body weight might not be enough to treat infections caused by bacteria with minimum inhibitory concentration (MIC) at or above 0.2 microg/mL, based on the calculated area under the inhibitory concentration (AUIC).

    Mummies associated with the ancient city of Akhmim in Egypt provide an important portal for radiologic research concerning the ancient Egyptian population. As part of an ongoing investigation, a mummy of Akhmimic derivation owned by the Academy of Natural Sciences in Philadelphia, Pennsylvania, was scanned with a 16-detector row computed tomographic scanner. The resultant images helped confirm that the mummy was that of a female in her late teens. Although the deliberate omission of hieroglyphic texts on the painted coffin rendered the deceased individual anonymous, it is noteworthy that great care had been taken in preparing the corpse for burial. The mummy represents conscientious work by the embalmers, work that is broadly consistent with methods used during the early Ptolemaic period for well-to-do persons. Features of bodily decomposition, including the rotary dissociation of the C1 and C2 vertebral bodies and a missing right patella, point to neglect of the body prior to its recovery and mummification. The fact that the body was well prepared but thinly wrapped and interred in an uninscribed coffin further suggests that the deceased was not of the community that eventually performed the mummification. This evidence is not inconsistent with a scenario involving the body's postmortem immersion in water. Although it cannot be determined with certainty whether the deceased was a drowning victim, it appears that the treatment of the body followed protocols developed in connection with an ancient Egyptian tradition that persons dying in, or retrieved from, the Nile River were embalmed with special care.

    As a nondestructive method of historical and anthropologic inquiry, imaging has played an important role in mummy studies over the past several decades. Recent technologic advances have made multidetector computed tomography (CT) an especially useful means for deepening the present understanding of ancient cultures by examining preserved human remains. In April 2011, three ancient Egyptian human mummies from the Redpath Museum of McGill University were examined with 320-section multidetector CT as part of the IMPACT Radiological Mummy Database project headquartered at the University of Western Ontario. Whole-body scanning was performed with a section thickness of 0.5 mm and a peak voltage of 120 kVp, and the raw CT datasets were postprocessed by using smooth body and high-resolution bone convolution filters. Two of the mummies were scanned at different energy levels (80 and 135 keV). The high-resolution CT scans revealed the details of mummification and allowed observations about the socioeconomic and health status of the human subjects based on both the mummification technique used and the appearance of the remains, particularly the bones and teeth. The paleopathologic information obtained from the scans confirmed some findings in studies performed in the same mummies in the late 19th and 20th centuries. The CT scans also demonstrated a high degree of variability in Egyptian mortuary practice, variability that is not generally recognized in the literature. Unusual features that were observed included a relatively uncommon retained heart in mummy RM2718, retained lungs in a mummy from which the heart had been extracted (RM2720), and a cartonnage plaque placed over the left abdomen of a mummy that had been eviscerated transperineally (RM2717).

    Traditional theories on ancient Egyptian mummification postulate that in the prehistoric period (i.e. the Neolithic and Chalcolithic periods, 5th and 4th millennia B.C.) bodies were naturally desiccated through the action of the hot, dry desert sand. Although molding of the body with resin-impregnated linen is believed to be an early Pharaonic forerunner to more complex processes, scientific evidence for the early use of resins in artificial mummification has until now been limited to isolated occurrences during the late Old Kingdom (c. 2200 B.C.), their use becoming more apparent during the Middle Kingdom (c. 2000-1600 BC). We examined linen wrappings from bodies in securely provenanced tombs (pit graves) in the earliest recorded ancient Egyptian cemeteries at Mostagedda in the Badari region (Upper Egypt). Our investigations of these prehistoric funerary wrappings using a combination of gas chromatography-mass spectrometry (GC-MS) and thermal desorption/pyrolysis (TD/Py)-GC-MS have identified a pine resin, an aromatic plant extract, a plant gum/sugar, a natural petroleum source, and a plant oil/animal fat in directly AMS-dated funerary wrappings. Predating the earliest scientific evidence by more than a millennium, these embalming agents constitute complex, processed recipes of the same natural products, in similar proportions, as those utilized at the zenith of Pharaonic mummification some 3,000 years later. The antibacterial properties of some of these ingredients and the localized soft-tissue preservation that they would have afforded lead us to conclude that these represent the very beginnings of experimentation that would evolve into the famous mummification practice of the Pharaonic period.

    Full Text Available Hip disorders in a pediatric population are a diagnostic challenge. The aim of the study is to assess the role of magnetic resonance imaging (MRI in the evaluation of non-traumatic hip disorders in a series of Egyptian patients and to review the literature on the most common hip conditions. Seventy two consecutive patients [40 males (55.6% and 32 females (44.4] with acute onset of hip complaints unrelated to trauma or falls were recruited. All patients underwent an initial full clinical assessment and blood tests as well as contrast enhanced MRI of both hips. The most common diagnosis in this group of Egyptian patients was transient synovitis in 29 (40.3% cases, followed by seronegative enthesopathy and arthropathy syndrome in 8 (11.1%, septic arthritis in 10 (13.9%, tuberculous arthritis in 4 (5.6%, sickle-cell disease in 7 (9.7%, complicated with septic arthritis in 3 (4.2%, transient bone marrow edema (BME in 3 (4.2%, osteomyelitis in 2 (2.8%, osteosarcoma in 2 (2.8%, sciatic nerve injury in 1 (1.4%, leukemia with BME in 1 (1.4%, coxa vara of both hips and L5/S1 facet joint ankylosis in 1 (1.4%, and a benign bone cyst in 1 (1.4%. MRI studies showed hip effusion in a total of 51 patients (70.8%, joint space narrowing in 9 (12.5%, and BME in 15(20.8%. MRI is a sensitive tool for assessing hip disorders in a pediatric population and can play an important role in both diagnosis and management of different hip disorders, irrespective of the underlying pathology.

    Full Text Available Abstract Introduction Benign neonatal hemangiomatosis is a condition in which multiple cutaneous hemangiomas appear at birth or shortly thereafter; visceral complications are absent. Here, we report a case of a consumption hypothyroidism in an Egyptian baby with benign neonatal hemangiomatosis. Case presentation An 8-month-old Egyptian boy with benign neonatal hemangiomatosis was referred to our institution for evaluation of developmental delay. Initial examination revealed a quiet baby who was able to sit only with support. He had hypotonia, a large anterior fontanelle, puffy eyes, cold extremities, hypothermia, bradycardia, and abdominal distension. An examination of his skin revealed more than 100 dome-shaped red-purple cutaneous hemangiomas that varied in size from 5 to 10mm on the back, the abdomen and the extremities without mucus membrane involvement. He had low serum free thyroxine concentration and triiodothyronine levels and high thyroid-stimulating hormone and reverse-triiodothyronine levels. A work-up that involved appropriate imaging ruled out visceral involvement. Based on the above mentioned data, a diagnosis of consumptive hypothyroidism due to benign neonatal hemangiomatosis was made. He was started on oral thyroid medication which was gradually increased to 90μg L-thyroxine daily (15μg/kg/day. After three months of treatment, he was able to sit alone without support and he had normal levels of thyroid-stimulating hormone and serum free thyroxine. Conclusion Thyroid function should be assessed periodically in babies with benign neonatal hemangiomatosis, especially if symptoms of hypothyroidism appear or the size and number of hemangiomatosis increase rapidly. Moreover, high doses of L-thyroxine may be needed to achieve euthyroidism during the infancy.

    There are scanty data on the prevalence of vitamin D deficiency and its relation to disease activity among patients with juvenile-onset systemic lupus erythematosus (JoSLE) in the Middle East and North Africa, an area known to be endemic for vitamin D deficiency and insufficiency. The aim of this study was, therefore, to study vitamin D status and its relation to disease activity and parameters in Egyptian patients with JoSLE. Serum levels of 25(OH) D3 in 70 JoSLE patients were compared to 40 age-, sex-, and body mass index-matched healthy controls. The 25(OH) D3 was determined by enzyme-linked immunosorbent assay. Information regarding the medical history, clinical symptoms, and signs was registered at the time of serum sampling. Disease activity of SLE was evaluated according to the SLEDAI score. The mean level of serum 25(OH) D3 was 12 ± 3.7 in JoSLE patients compared to 21 ± 3.5 ng/mL in normal controls (p 30 ng/mL. There was no significant correlation between serum levels of 25(OH) D3 and the demographic data, medication used, and some laboratory data of patients with JoSLE. Disease activity score in our patients was insignificantly correlated with serum levels of 25(OH) D3. In spite of vitamin D supplementation in Egyptian JoSLE patients and the presence of vitamin D insufficiency in the control group, there are still significantly lower levels of vitamin D in JoSLE compared to normal controls.

    Full Text Available Background: Breast cancer (BC is usually diagnosed in late stages in countries with limited resources. Early detection of BC is likely to improve the outcome of the disease for women in these areas. Objective: The aim of this study was to understand the possible personal, economic, and systems barriers to BC screening in a sample of Egyptian women. Materials and Methods: A cross-sectional study was conducted in family health centers representing the seven districts of Alexandria governorate, Egypt. A total of 612 women were randomly selected from the chosen centers. Results: In this sample of Egyptian women, the most frequently identified potential barriers to BC screening were the following: 81.8% would not seek care until they were ill, 77% were unwilling to have a mammogram until it was recommended by the doctor, 71.4% blamed the, lack of privacy, 69.2% thought that medical checkups were not worthwhile, and 64.6% blamed the cost of services. The study further revealed that women of lower education, women in the lower income category, women who did not do paid work, those who had poor knowledge of the risks of BC, and women with no family history of BC were more likely to perceive different screening barriers compared with their counterparts. Conclusion: Many potential personal, economic, and health system barriers were identified. Addressing these barriers by increasing the awareness of BC and dealing with the misconceptions that the women have can help the policy makers to design more culturally relevant strategies to motivate women to utilize screening services.

    Full Text Available Aims: To determine whether the LV Prasad-Functional Vision Questionnaire (LVP-FVQ could be used to assess self-reported visual function and quality of visual life in Egyptian school aged children. Materials and Methods: The LVP-FVQ was used to assess the quality of visual function in school-age children. All subjects were students at the time of assessment. Subjects underwent a visual function assessment that included distance and near visual acuity, contrast sensitivity, color vision and visual field examination where possible. Data analysis were for both descriptive and inference statistics. A P < 0.05 was considered statistically significant. Results: Fifty children aged 11.28 ± 3.5 years (range, 5 years to 18 years with moderate-to-severe visual impairment most of their lives were enrolled. Twenty-two subjects (44% had albinism, 18 (36% subjects had hereditary retinal dystrophy, 6 (12% subjects had cone dystrophy, 2 (4% subjects had bilateral amblyopia and 2 (4% subjects had congenital coloboma without other disabilities. The four most difficult tasks were related to the following daily activities alluded to in the questionnaire such as reading a textbook at arms length, copying from the blackboard, seeing somebody across the road and identifying colors. There was no statistically significant association between the demographic variables and the level of visual functioning, sex, age, type of school, family history or consanguinity (P > 0.05 for all variables. Conclusion: LVP-FVQ can be used to screen Egyptian children with visual impairment. Input and integration of the parents and the school teachers to evaluate the child s behavior at home and the school is essential to developing a balanced questionnaire.

    Objective: To evaluate the synergetic effect of an ethanolic extract of Egyptian propolis in immunization of BALB/c mice with Taenia saginata(T. saginata) crude antigen against bovine cysticercosis, with reference to its effects on liver and kidney functions.Methods: Sixty female mice BALB/c strain weighing 20 to 25 g and 6-8 weeks old were randomly allocated into six groups of ten mice each. Mice in groups 1 and 2(G1 and G2) were immunized intraperitoneally with 100 μg of T. saginata crude antigen in 100 μL phosphate buffer saline emulsified in Freund’s adjuvant. Besides, the mice in G2 were administered with propolis extract simultaneously with immunization. Control mice were either administered with propolis extract(G3) or injected with the same volume of phosphate buffer saline emulsified in Freund’s adjuvant(G4). The mice in G5 were non-immunized infected control while, those in G6 were non-immunized non-infected control. Two weeks after the last immunization, each mouse was challenged intraperitoneally with 5 000 oncospheres except those of G6. Ethanolic extract of propolis was prepared at a dose 50 mg/kg body weight.Results: After 24 weeks of challenge, the mice in G2 showed the highest level of protection(100%), with no cyst being detected rather than mice in G1(33.3% protection). Additionally,the ELISA results, in this study, showed higher antibody titer in G2 with reduction the alteration in liver and kidney functions compared to G1.Conclusions: Egyptian propolis could increase the level of protection against experimental challenge infection with T. saginata eggs when administered simultaneously with immunization. Furthermore, it could enhance the production of antibodies to immunized antigen and decrease the alteration in liver and kidney functions.

    Full Text Available This study was undertaken to investigate the prevalence and antibiotic resistance of food borne bacterial contamination in some Egyptian food. Total viable bacteria and total coliform bacteriawere isolated from different sources of food; carbohydrates (bread, flour and basbousa, vegetables (outer and inner tissues of potato and outer and inner tissues of cucumber and proteins (mincedmeat, cheese and milk. The study resulted in maximum value of total viable bacteria found in outer tissue of potato 68X104±1.0, while the minimum value found in inner tissues of potato andcucumber. The study resulted in total coliform was maximum value in minced meat 6.4X103±0.3. Basbousa and inner tissue of potato and cucumber were free from coliforms. The ability of isolatesto producing proteolytic enzymes was tested, we found that 326 isolate (63.92% from all isolates had this ability, thus we selected most 2 potent proteolytic isolates. The two isolates were identifiedas Bacillus cereus and Escherichia coli. The identification confirmed by microlog 34.20 system and 16SrRNA for two isolates and the same result was founded. Sensitivity tested for the most potentproteolytic species to 12 of the most commonly used antibiotics in the Egyptian pharmacy. The results showed that all species were sensitive to most of antibiotics, except B. cereus which was strongly susceptible to azteronam and ceftazidim. The data showed that raw meat, cooked food products, and raw milk were most commonly contaminated with foodborne pathogens and many pathogens were resistant to different antibiotics. The study provided useful information for assessment of the possible risk posed to consumers, which has significant public health impact.

    Full Text Available In recent years several international scholars have started to move beyond the social and political effect of blogging to define blogs in terms of literary writing (See Fitzpatrick, 2006; Himmer 2004; Van Dijk, 2004. Also in the Arab world, the fact that several blogs have been turned into books and have had considerable success, has provoked a debate over the literary status of blogs: while some critics hail them as a new literary experiment, others claim that they do not have the legitimacy to be included in the category of adab (literature. This has perhaps to do with the fact that in the Arab world (as elsewhere printed books enjoy more prestige; but also with the fact that the Arab notion of adab is gradually coinciding, though still differing from the European notion of “literature”, and this defines the boundaries of the literary field. In other words, to claim that a work is “literary” because it has aspects of “literariness”, does not wholly correspond to saying that it is adabī, i.e. “literary” for Arab critics. In this article I will discuss aspects of literariness and adab-icity by means of an analysis of the blog al-Kanabah al-Ḥamrā (The Red Sofa, written by the Egyptian Bilāl Ḥusnī. The blog has been reviewed in several Egyptian newspapers and literary websites as “an interactive fiction” or a “adabī/literary and visual blog”. However, its style, contents and materiality challenge both our notion of “literature” and the Arab concept of adab.

    Full Text Available Background: Type 1 diabetes mellitus (T1D is a polygenic autoimmune disease. Vitamin D is a potent modulator of the immune system and has been implicated in T1D pathogenesis and prevention. Vitamin D-binding protein (VDBP is the main systemic transporter of vitamin D and is essential for its cellular endocytosis. Two frequent single nucleotide polymorphisms (SNPs, in exon 11 of the VDBP gene, result in amino acid variants: (rs7041 GAT→GAG substitution replaces aspartic acid by glutamic acid in codon 416; and (rs4588 ACG→AAG substitution in codon 420 leads to an exchange of threonine for lysine. These VDBP variants lead to differences in the affinity for vitamin D.Objective: The objective was to evaluate the association of these 2 VDBP gene SNPs with T1D in Egyptian children.Material and Method: Unrelated 59 children with T1D and 65 healthy controls were included in this study. The sequence of VDBP exon 11, which contains both examined SNPs, was analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP.Results: The frequency of Asp/Glu alleles, at codon 416, was 35.6/64.4% in T1D patients and 44.6/55.4% in controls (P=0.15. At codon 420 the frequency of Thr/Lys alleles were 88.1/11.9% and 87.7/12.3% (P=0.91, respectively. Distributions of genotypes at both loci, and the common haplotypes constructed by them, were also very similar in both groups (P> 0.05.Conclusion: DNA polymorphisms in the VDBP gene are not associated with T1D in Egyptian children..

    Full Text Available Traditional theories on ancient Egyptian mummification postulate that in the prehistoric period (i.e. the Neolithic and Chalcolithic periods, 5th and 4th millennia B.C. bodies were naturally desiccated through the action of the hot, dry desert sand. Although molding of the body with resin-impregnated linen is believed to be an early Pharaonic forerunner to more complex processes, scientific evidence for the early use of resins in artificial mummification has until now been limited to isolated occurrences during the late Old Kingdom (c. 2200 B.C., their use becoming more apparent during the Middle Kingdom (c. 2000-1600 BC. We examined linen wrappings from bodies in securely provenanced tombs (pit graves in the earliest recorded ancient Egyptian cemeteries at Mostagedda in the Badari region (Upper Egypt. Our investigations of these prehistoric funerary wrappings using a combination of gas chromatography-mass spectrometry (GC-MS and thermal desorption/pyrolysis (TD/Py-GC-MS have identified a pine resin, an aromatic plant extract, a plant gum/sugar, a natural petroleum source, and a plant oil/animal fat in directly AMS-dated funerary wrappings. Predating the earliest scientific evidence by more than a millennium, these embalming agents constitute complex, processed recipes of the same natural products, in similar proportions, as those utilized at the zenith of Pharaonic mummification some 3,000 years later. The antibacterial properties of some of these ingredients and the localized soft-tissue preservation that they would have afforded lead us to conclude that these represent the very beginnings of experimentation that would evolve into the famous mummification practice of the Pharaonic period.

    Full Text Available Abstract Introduction Hutchinson-Gilford progeria syndrome is a rare genetic disorder. It is reported to be present in one in eight million and is characterized by severe growth failure, early loss of hair, lipodystrophy, scleroderma, decreased joint mobility, osteolysis, early atherosclerosis and facial features that resemble those of an aged person. Apart from diabetes mellitus, there are no reported abnormalities of thyroid, parathyroid, pituitary or adrenal function. Here, we report the case of a 10-year-old Egyptian child with Hutchinson-Gilford progeria syndrome and hypoparathyroidism. Case presentation A 10-year-old Egyptian boy was referred to our institution for an evaluation of recurrent attacks of muscle cramps, paresthesia of his fingertips and perioral numbness of two months duration. On examination, we found dilated veins present over his scalp with alopecia and frontal bossing, a beaked nose, thin lips, protruding ears, a high pitched voice with sparse hair over his eyebrows and eyelashes and micrognathia but normal dentition. His eyes appeared prominent and our patient appeared to have poor sexual development. A provisional diagnosis of progeria was made, which was confirmed by molecular genetics study. Chvostek's and Trousseau's signs were positive. He had low total calcium (5.4 mg/dL, low ionized calcium (2.3 mg/dL, raised serum phosphate (7.2 mg/dL, raised alkaline phosphatase (118 U/L and low intact parathyroid hormone (1.2 pg/mL levels. He was started on oral calcium salt and vitamin D; his symptoms improved with the treatment and his serum calcium, urinary calcium and alkaline phosphates level were monitored every three months to ensure adequacy of therapy and to avoid hypercalcemia. Conclusion Routine checking of serum calcium, phosphorus and parathyroid hormone will help in the early detection of hypoparathyrodism among children with progeria.

    Full Text Available Abstract Introduction X-linked congenital adrenal hypoplasia is a rare developmental disorder of the human adrenal cortex and is caused by deletion or mutation of the dosage-sensitive sex reversal adrenal hypoplasia congenita critical region of the X chromosome, gene 1 (DAX-1 gene. Most affected children present with failure to thrive, salt wasting and hypoglycemic convulsions in the first months of life. Hypospadias affects approximately one in 250 live male births. Mutations in the mastermind-like domain-containing 1 (MAMLD1 gene have been implicated as one of the causes of hypospadias in children. To the best of our knowledge, an association between congenital adrenal hypoplasia due to a DAX-1 mutation and hypospadias due to mutation of the MAMLD1 gene has not previously been reported in the literature. Case presentation A 35-day-old male Egyptian baby was referred to our institution for the evaluation of a two-week history of recurrent vomiting associated with electrolyte imbalance. On examination, our patient was found to have hypotension and dehydration. A genital examination showed distal penile hypospadias with chordee and normal testes. He had hyponatremia, hyperkalemia, hypoglycemia and metabolic acidosis. Endocrinological investigations revealed low levels of cortisol, 17-hydroxyprogesterone and aldosterone, with a high level of adrenocorticotrophic hormone. A provisional diagnosis of congenital adrenal hypoplasia associated with hypospadias was made. A molecular genetics study confirmed the diagnosis of X-linked congenital adrenal hypoplasia due to DAX-1 mutations and hypospadias due to MAMLD1 mutation. He was started on hydrocortisone and fludrocortisone treatment. After three weeks of treatment, his symptoms improved and his blood sugar, sodium, potassium and cortisol levels normalized. Conclusions We report the case of an Egyptian baby with an association of congenital adrenal hypoplasia due to DAX-1 mutation and hypospadias due

    Full Text Available Abstract Background Recent guidelines stressed the need to adopt different values of waist circumference (WC measurements to define abdominal obesity in different ethnic groups. The aim of this study is to identify WC cutoff points in normotensive and hypertensive subjects which are diagnostic of abdominal obesity in a Middle Eastern population and the prevalence of abdominal obesity in a nationwide sample. Methods Data were collected during phase-2 of the Egyptians National Hypertension Project survey. Blood pressure, anthropometric measurements and laboratory studies were performed according to a standardized protocol by trained personnel. To derive the cutoff points for WC, we applied the factor analysis on CV risk factors: diabetes mellitus, decrease in HDL-C and increase in LDL-C, triglycerides and left ventricular mass index by echocardiography. Results The sample included 2313 individuals above the age of 25 years. WC values (mean ± SD were 88 ± 14 cm and 95 ± 14 cm for normotensive (NT and hypertensive (HT men respectively, and 89.6 ± 14.7 cm and 95.7 ± 15.9 cm for NT and HT women respectively. Applying factor analysis, the weighted average cutoff points were 93.5 cm for both NT and HT men and 91.5 and 92.5 cm for NT and HT women respectively. Based on these thresholds, the prevalence of abdominal obesity was 48% in men and 51.5% in women. Conclusion This is the first report of specific abdominal obesity cutoff points in a Middle Eastern country. The cutoff points were different from the Europid standards. There is a high prevalence rate of abdominal obesity among Egyptians which is associated with increased prevalence of cardiometabolic risk factors.

    2012-04-01

    Full Text Available Abstract Introduction Familial glucocorticoid deficiency, or hereditary unresponsiveness to adrenocorticotropic hormone, is a rare autosomal recessive disease characterized by glucocorticoid deficiency in the absence of mineralocorticoid deficiency. It may present in infancy or early childhood with hyperpigmentation, failure to thrive, recurrent infections, hypoglycemic attacks and convulsions that may result in coma or death. Here, we report the case of an 18-month-old Egyptian boy with familial glucocorticoid deficiency. Case presentation An 18-month-old Egyptian boy was referred to our institution for evaluation of generalized hyperpigmentation of the body associated with recurrent convulsions; one of his siblings, who had died at the age of nine months, also had generalized hyperpigmentation of the body. The initial clinical examination revealed generalized symmetrical deep hyperpigmentation of the body as well as hypotonia, normal blood pressure and normal male genitalia. He had low blood glucose and cortisol levels, normal aldosterone and high adrenocorticotropic hormone levels. Based on the above mentioned data, a provisional diagnosis of familial glucocorticoid deficiency was made, which was confirmed by a molecular genetics study. Oral hydrocortisone treatment at a dose of 10 mg/m2/day was started. The child was followed up after two months of treatment; the hyperpigmentation has lessened in comparison with his initial presentation and his blood sugar and cortisol levels were normalized. Conclusion Familial glucocorticoid deficiency is a rare, treatable disease that can be easily missed due to nonspecific presentations. The consequences of delayed diagnosis and treatment are associated with high rates of morbidity and mortality.

  8. Can astronomy enhance UNESCO World Heritage recognition? The paradigm of 4th Dynasty Egyptian pyramids

    The pyramids of Egypt, notably those of the 4th Dinasty as Giza, have always be considered an unmistikable part of human world heritage as the only surviving wonders of the Ancient World. Their majesty, technical hability and innovative character have always beeen considered as representative of ancient Egyptian ingenuity. However, past and present fringe theories about the pyramids and astronomy have always polluted the role of our discipline in the design, construction and symbolism of these impressive monuments. This is indeed unfear. Fortunately, things have started to change in the last couple of decades and now astronomy is interpreted as a neccessary tool for the correct interpretation of the astral eschatology present in the 5th and 6th Dynasty Texts of the Pyramids. Although the pyramid complexes of the 4th Dynasty are mute, there is however recent research showing that a strong astral symbolism could be hidden in many aspects of the complex architecture and in the design of these exceptional monuments. This idea comes from several hints obtained not only from planning and construction, but also from epigraphy and the analysis of celestial and local landscapes. Chronology also plays a most relevant role on this. The pyramid complexes of the 4th Dynasty at Meidum, Dahshur, Giza and Abu Rowash -- all of which enjoy UNESCO World Heritage recognition -- willl be scrutinized. As a consequence, we will show how astronomy can certainly enhance the face value of these extraordinary monuments as a definitive proof of the ancient Egyptian quest for Ma'at, i.e. their perennial obsesion for Cosmic Order.

    The essential oils isolated from the leaves and green branches of the Egyptian navel orange trees were analyzed by GC and GC/MS. A total of 33 and 24 compounds were identified from the oils of the leaves and branches accounting for 96.0% and 97.9%, respectively, of the total detected constituents. The major ones were sabinene (36.5; 33.0%), terpinen-4-ol (8.2; 6.2%), δ-3-carene (7.0; 9.4%), limonene (6.8; 18.7%), trans-ocimene (6.7; 6.1%), and β-myrcene (4.5; 4.4%). The antimicrobial activities of both oils were evaluated using the agar-well diffusion method toward three representatives for each of Gram-positive bacteria, Gram-negative bacteria, and fungi. The oil of leaves was more effective as antimicrobial agent than that of the branches. Streptococcus pyogenes, Staphylococcus aureus, Salmonella typhimurium, and Aspergillus fumigatus were the most sensitive bacteria and fungi by the leaves oil. PMID:26948682

    The genus Actorthia Kröber, 1912 was described based on a single female from Tourrah (Egypt) and is revised for the first time since the original description. Actorthia khedivialis (Becker, 1912) is newly synonymized with A. frontata (Kröber, 1912) based on examination of the type specimens of both species recently discovered in the Cairo University Collection (Egypt) and Natural History Museum (Austria), respectively. Actorthia efflatouni Kröber, 1925 is confirmed as a synonym of A. micans (Kröber, 1923) and Actorthia olivierii (Macquart, 1840) is transferred to Phycus. Actorthia pulchella Kröber, 1927 is recorded in Israel for the first time. The three Egyptian species of Actorthia are diagnosed and illustrated along with colour images of the type specimens, and a key to the Egyptian species is included. PMID:24698910

  12. Hands of beauty, hands of horror: fear and Egyptian art at the Fin de Siècle.

    Science.gov (United States)

    Briefel, Aviva

    2008-01-01

    This essay examines the gothicization of Egyptian manual productions in late-Victorian mummy narratives. These narratives often isolate the mummy's hand as a signifier of craftsmanship, a troubling object for a culture that was mourning the figurative loss of its artisans' hands to mechanized production. Focusing on Bram Stoker's 1903 novel, The Jewel of Seven Stars, I contend that the horror of the mummy's hand emanates from its ambiguous position as an artifact that is itself a means of production. It displaces Friedrich Engels's conception of the Western hand as a self-creating appendage into the atavistic domain of a long-lost Egyptian tradition, and in doing so, it forces the English observer to recognize the irrecoverable nature of aesthetic craftsmanship. Brought into violent contact with the creative potential of the mummy's hand, the characters in Stoker's novel try to disassociate the mummy from manual production but only succeed in confirming their own status as products of a mechanized age.

Sampling units used were regional divisions (comarques. High density of Bearded Vulture was principally linked to areas with scant vegetation and low human population density. In contrast, high densities of both the Egyptian and Eurasian Griffon Vultures were associated with availability of trophic resources (sheep and goats. Positive effects were detected in relation to low density of inhabitants (Egyptian Vulture and altitudes between 1,000-2,000 m and landscape with low tree cover (Eurasian Griffon Vulture. The Bearded Vulture seemed to be the most selective species in relation to environmental characteristics while the Eurasian Griffon and the Egyptian Vultures displayed a higher degree of ecological plasticity. Future conservation actions should bear these results in mind in order to optimise management. Food resources from extensive livestock farming, in particular, seem fundamental for the conservation of scavenger species. Preference monitoring and conservation efforts are needed in the regions with highest vulture densities (Alta Ribagorça, Pallars Jussà and Alt Urgell, while regions with low vulture populations should be managed in order to favour the geographical expansion and recolonisation of zones currently not occupied by these species. Conservation priorities should be based on favouring extensive livestock practices, and as an alternative to muladares (traditional animal carcass disposal sites farmers should be encouraged to leave animal carcasses in the field, while ensuring compliance with health regulations.

    The present work was established to determine the applicability of local Egyptian kaolinite and blast furnace slag (BFS) as raw materials toward the synthesis of geopolymers and subsequent immobilization of cobalt-60, which is one of the most abundant radionuclides generated in radioactive waste streams in Egypt. XRF, XRD, FT-IR, and SEM techniques were used to characterize the local raw materials and their corresponding alkali activated products. Metakaolin (MK) was obtained by thermal treatment of Egyptian Sinai kaolin 750 °C/4 h. MK and five different BFS content (5, 10, 30, 50 and 80%) were used to synthesize geopolymeric matrices using an alkaline activator of Si-modulus = 1.35 at solid/liquid ratios of 0.8. Compressive strength tests were performed indicating that 50% BFS addition gave the highest values of compressive strength. The IAEA standard leaching tests of cobalt-60 from the solidified waste matrices were carried out. The effective diffusion coefficients of cobalt-60 radionuclides from the solidified waste matrices were calculated to be in the order of 10{sup −14} cm{sup 2}/s. Leaching of radionuclides was examined to be controlled by the wash-off mechanism with very acceptable values. These results gave encouragement that the tested Egyptian raw materials can be conveniently applied for the synthesis of geopolymers that can be used as a low-cost and high-efficiency materials for the immobilization of radioactive waste.

  1. Notes on the history of the radiological study of Egyptian mummies: from X-rays to new imaging techniques.

    Cosmacini, P; Piacentini, P

    2008-08-01

    A few centuries after the practice of mummification was finally abolished in the seventh century A.D., mummies began to capture the collective imagination, exerting a mysterious fascination that continues to this day. From the beginning, the radiological study of Egyptian mummies permitted the collection not only of medical data but also of anthropological and archaeological evidence. The first radiological study of an Egyptian mummy was performed by Flinders Petrie shortly after the discovery of X-rays in 1895, and since then, radiology has never stopped investigating these special patients. By the end of the 1970s, computed tomography (CT) scanning permitted more in-depth studies to be carried out without requiring the mummies to be removed from their cartonnage. CT images can be used to obtain a three-dimensional reconstruction of the mummy that provides important new information, in part thanks to the virtual endoscopy technique known as "fly through". Moreover, starting from CT data and using sophisticated graphics software, one can reconstruct an image of the face of the mummified individual at the time of his or her death. The history of imaging, from its origins until now, from the simplest to the most sophisticated technique, allows us to appreciate why these studies have been, and still are, fundamental in the study of Egyptian mummies.

    2011-05-01

    Our study describes how brown-necked ravens ( Corvus ruficollis) are able to take advantage of an ordinarily inaccessible, high-quality food source by relying upon their innovative and manipulative thinking capabilities to exploit methods used by Egyptian vulture ( Neophron percnopterus) to overcome the problem. In five observed interactions, the ravens were first seen in the vicinity of an abandoned clutch of ostrich eggs ( Struthio camelus). The area was frequented by a pair of Egyptian vultures that bred on the cliffs across the road from the nature reserve. The Egyptian vulture exhibits tool use in birds, and is able to crack the hard shells of ostrich eggs by lifting a rock in the beak and pounding at the egg till it breaks open or cracks. If the egg is only cracked, the vulture inserts its narrow bill into the fissure and widens it by opening the mandibles. Pieces of eggshell are removed from around the crack in order to further open the egg. This is the point at which the pair of ravens attacked the vulture and harassed it till it abandoned the egg and left the area. The ravens then jointly enjoyed the contents of the egg which was otherwise inaccessible to them because of the strong egg shell.

    Lushnikova, A. V.

    In the article material from various cultural and linguistic sources (Indo-European - Slavic, Indo-Iranian; Uralo-Altaic, Tungus, Ancient Egyptian, Babylonian) is used in order to trace up the chronology of the designation of Ursa Majopr, a constellation which has been playing an important role for people different regions since ancient times. It was used for observing of the visible yearly motion of the Sun, for working out seasonal changes; being a circumpolar and non-hiding behind the horizon it has been perceived as a symbol of immortality, its peculiar positional change during a year lay down in plot of the Uralo-Siberian myths about a cosmic hunt for the Elk, myths about deluge. Data from Uralo-Siberian mythology are analyzed. Designations of Ursa Major in the form of a horned hoofed animal such as elk, deer, cow (Uralo-Altaic, Tungus, Slavic, Indo-Iranian languages; Ancient Greece, Crete, Ancient Egypt) and connected with it (or derived from it) denominations and images of "enclosed space" - "vehicle for travelling and carrying goods" (a wagon, a boat) - "instrument for hunting-fishing, a ritual thing" - "household construction" are taken in consideration. The conclusion is made that the transition of the Ursa Major designation from elk to bear could follow the general tendency to shift from so-called matriarchy to patriarchy, to substitute female deities with male ones, which was reflected "in the rise" of the predatory animal cults (not earlier than II mil. B.C.). To prove this, lexical examples of resemblance and coincidences in designation of homed hoofed (elk, deer) and predatory (bear, wolf) animals should be analyzed. Such a goal-directed investigation of the chronology of Ursa Major designations has never been carried out.

    Full Text Available Objective: To determine the best anthropometric measurement of obesity, and its optimal cutoff, that best predicts the presence of cardiovascular risk factors among adult Egyptian population. Methods: This is a cross-sectional study including a representative randomly chosen sample of the adult Egyptian population from all Alexandria Districts (the second largest governorate in Egypt based on the multistage random technique. It included 3209 subjects (1567 men, 1642 women aged 18–80 years from urban and rural areas. The response rate was 80.2%. History, blood pressure, and anthropometric measurements were taken. Laboratory investigations included fasting lipid profile, fasting plasma glucose, and serum uric acid. Different criteria of metabolic syndrome were used and compared. Receiver operator characteristic curve and Youden index were used to determine predictability and cutoffs. Results: Waist circumference (WC is the best to predict at least two other components of the metabolic syndrome as defined by the International Diabetes Federation (IDF. The optimal WC cutoffs were 100.5 and 96.25 cm for Egyptian men and women, respectively. The Joint Interim Statement definition (JIS of metabolic syndrome was the best to predict cardiovascular disease in both genders and diabetes mellitus in women. The prevalence of metabolic syndrome and abdominal obesity was 42.5%, 61%, respectively (ATPIII definition; 43.8%, 61% (American Heart Association definition; 44.3%, 76.4% (IDF definition; 33.8%, 51.7% (IDF definition with Egyptian cutoffs; and 41.5%, 51.7% (JIS with Egyptian cutoffs. Conclusion: WC cutoffs in Egyptians differ from those currently recommended. Prevalence of metabolic syndrome and abdominal obesity is high in Egypt, despite being lower on using the Egyptian cutoffs.

  8. Investigation of molecular markers related to fecundity in local egyptian sheep

    International Nuclear Information System (INIS)

    The present experimental work aimed to investigate a number of molecular makers that influence fecundity in local Egyptian sheep. In the present study, twenty two (11 twin producing crossbred ewes, 7 single lamb producing crossbred ewes, 2 crossbred rams from twin producing ewes and 2 pure bred rams from twin producing ewes) were tested. They were carefully selected from the records of the Egyptian Nuclear Research Centre. The ewes were selected for their twin production in three repetitive production cycles while the rams were selected for being produced from prolific ewes as above. The presence of the booroola fecundity gene (FecB) (FecB mutation in bone morphogenic protein receptor gene 1B (BMPR1B)) and the Inverdale gene (FecXI) (FecXI mutation in bone morphogenic receptor gene (BMP15)) using Forced restriction PCR of the FecB and FecXI mutations, 190 base pair (bp) was amplified using specific primer which was forward (5'-CCAGAGGACAATAGCAAAGCAAA -3') and reverse (5'-CAAGATGTTTTCATGCCTCATCAACAGGTC -3' ) and designed to introduce a point mutation in the resulting PCR products with FecB carrier sheep containing an AvaII restriction site (G|GACC). The FecB DNA test showed that there were no carriers for the FecB mutation in the selected prolific sheep sample. When a specific primer which was forward (5'-GAAGTAACCAGTGTTCCCTCCACCCTTTTCT-3') and reverse (5'-CATGATTGGGAGAATTGAGACC-3') used to test the presence of FecXI mutation no amplification resulted from DNA samples of the twin producing ewes while two amplified DNA fragments of molecular size 154 bp and 120 bp resulted from the single lamb producing females and male sheep under study. Serum samples were collected from sheep under study and tested using totallab 120 computer software analyses for Native protein gel images. Gel images revealed a protein pattern in twin producing ewe samples characterized by the presence of three bands with molecular weights 679.7, 524.3, and 431.1 kd and the absence two bands with

    Full Text Available Background: Hyperuricemia is commonly associated with hypertension. Also, it is well known to coincide with the metabolic syndrome but is still not recognized as a risk factor. So, we aimed to evaluate hyperuricemia among a sample of hypertensive Egyptians with normal renal function.Methods: this study was performed on 303 hypertensive patients aged 30-69 years. Patients were divided into 2 groups according to the level of uric acid: group 1 composed of 168 hypertensive hyperuricemic patient sand group2 composed of 135 hypertensive normouricemic patients. All patients were subjected to complete medical history and detailed clinical examination including body mass index (BMI, complete blood count (CBC, serum creatinine, BUN, FBS, cholesterol, triglycerides, uric acid, sodium, potassium, urinary uric acid, urinary creatinine, urinary uric acid to creatinine ratio and fractional excretion of uric acid(FEUA.Results: The overall prevalence of hyperuricemia was 55.4%. Uric acid correlated significantly with age (p0.05. Serum uric acid found to correlate significantly (p<0.001 with urinary uric acid, urinary creatinine and negatively with FEUA denoting early tubular defect of the kidney. Also, Urinary uric acid, urinary creatinine and urinary uric acid/creatinine ratio were higher in group 1than in group 2 (p values were<0.001, <0.001 and <0.05 respectively. FEUA was found to be significantly lower in group 1 than in group 2 (p<0.01. We found, also, that serum sodium level was significantly higher in the hyperuricemic group than in the normouricemic group (p<0.001 denoting the role of Na+ in the development of hypertension and defective renal excretion of uric acid.Conclusion: We conclude that the incidence hyperuricemia in our sample of Egyptian hypertensive patients was (55.4%. Impaired renal clearance of uric acid occurs before deterioration of GFR. Serum uric acid should be measured in all cases of hypertension together with BMI, total cholesterol

    Full Text Available Abstract Background Medical research must involve the participation of human subjects. Knowledge of patients' perspectives and concerns with their involvement in research would enhance recruitment efforts, improve the informed consent process, and enhance the overall trust between patients and investigators. Several studies have examined the views of patients from Western countries. There is limited empirical research involving the perspectives of individuals from developing countries. The purpose of this study is to examine the attitudes of Egyptian individuals toward medical research. Such information would help clarify the type and extent of concerns regarding research participation of individuals from cultural, economic, and political backgrounds that differ from those in developed countries. Methods We conducted semi-structured interviews with 15 Egyptian individuals recruited from the outpatient settings (public and private at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. Thematic analysis followed. Results All individuals valued the importance of medical research; however most would not participate in research that involved more than minimal risk. Individuals were comfortable with studies involving surveys and blood sampling, but many viewed drug trials as being too risky. All participants valued the concept of informed consent, as they thought that their permission to be in a research study was paramount. Many participants had discomfort with or difficulty in the understanding several research concepts: randomization, double-blind, and clinical equipoise. Trust in the physicians performing research was important in deciding to participate in clinical research. The small sample size and the selection bias associated with obtaining information from only those who agreed to participate in a research study represent limitations in this study. Conclusion Overall, individuals in our sample recognize

    Full Text Available The Egyptian Revolution on January 25—part of the 2011 Arab Spring—and the consequent June 30, 2013 Revolution have marked important turning points in the history of modern Egypt. The curricula and courses offered by Egyptian universities, as well as their academic activities and employment structure, have been greatly affected by these momentous events. Furthermore, the revolutions have opened a wider territory of freedom and emboldened both staff members and students. This paper attempts to answer questions related to the changes that have occurred with regard to the university courses, activities and structures. The paper additionally seeks to explore Egypt’s future and the possible ways that its people will defend and retain their dearly earned freedom. The paper is based on the writer’s personal experience as an associate professor in the English Department and in the Faculty of Education at Alexandria University. The paper is further influenced by the writer’s experiences as an elected member of the committee that observed—after twenty years of appointment by the National Security Department—the new elections for deans and heads of departments; the same committee also moderated debates among the candidates for these posts. As a teacher, I started a new course on revolutionary literature—which I personally designed and taught—and another on politics and media in collaboration with a colleague. From 2011 onward, I have linked and adjusted the materials of mandatory courses, “American Studies,” “18th Century English Novel” and “Contemporary Novel” to our revolutions and to current events. I constructed holistic courses by using the three domains of learning: the cognitive, the affective and the psychomotor. The paper will discuss the way I used Bloom and Krathwohl taxonomies in combination with other methods to cover these domains. This has made the courses more authentic and livelier to the learners, encouraging

  15. A study on hormonal control of calcium homeostasis in egyptian women

    International Nuclear Information System (INIS)

    This investigation was conducted to study the possible role of circulating hormones that regulate the calcium flux, in addition to serum levels of the inorganic mineral contents, calcium and phosphorus, on the pathogenesis of post-menopausal osteoporosis in egyptian women. The investigation studied also the response of these variables to both of estradiol withdrawal and age progress. Five groups of 11 postmenopausal osteoporotic (mean age 73 -+ 2.3 years), 26 postmenopausal women (mean age 56.2 -+ 2.4 years), 17 premenopausal women (mean age 48.8 -+ 0.7 years), 26 premenopausal women (mean age 41.5 -+ o.7 years) and 11 young adult premenopausal women(mean age 27.3 -+ 0.9 years) were recruited for this study. The post-peri- and pre- groups were further classified into subgroups according to their chronological age. Serum was assayed for parathyroid hormone (PTH), 25-hydroxyvitamin D, (25-OHD3), calcitonin (CT) total calcium (Ca), and inorganic phosphorus (ph), concentrations of estradiol (E2) in all subjects were also assayed for further correlation. The obtained data showed that the levels of hormones were not significantly changed among the different groups and subgroups leading to normal calcium homeostasis. PTH and total calcium were significantly correlated with both estrodial levels and chronological age

    We carried out an exploratory historical biology study using temporally distinguished groups of predynastic-Early Dynastic male crania from the region of Upper Egypt. The objectives were, first, to determine the overall pattern of phenetic affinity between temporally sequential series and in relation to the earliest series and, second, to explore the possible meanings of the pattern of relationship to sociohistorical change. The cranial series were designated early predynastic, late predynastic, terminal predynastic, and Dynasty I. Craniometric phenetic affinity was ascertained using Mahalanobis distances; a 5% level of probability was chosen for significance. The distance matrix values were ordered into hierarchies of dissimilarity from each series (distance hierarchies) and tabulated for time-successive groups, including the temporally earliest series (i.e., serialized by time). The principal observations were as follows. The overall pattern was not one in which the values between all series were statistically insignificant; nor was it one of consistent sequential increase of biological distance from the earliest series. There was a notable and statistically significant distance between the early and late predynastic groups, with the late and terminal predynastic groups mutually having the lowest and statistically insignificant distances with each other. The value between the terminal predynastic and Dynasty I series was generally larger than the values between other groups and was statistically significant. The overall pattern is possibly consistent with archeological interpretations that postulate increasing intraregional interactions during the late and terminal predynastic periods and the rise of an Egyptian state that eventually included northern Egypt.

  17. Radiation measurements in Egyptian pyramids and tombs -- occupational exposure of workers and the public

    International Nuclear Information System (INIS)

    A radiation survey of seven archaeological sites within Egyptian pyramids and tombs has been conducted in the Saggara area. Measurements were made of radon (222Rn) and its short-lived decay products (progeny), as well as thoron (220Rn) progeny and γ-radiation. The results of these measurements have been used to calculate the maximum annual effective dose (MAD) and other important occupational radiation exposure variables. It was found that for the limited time to which occupational workers and visitors were exposed, their respective MAD values were lower than that recommended by the regulatory agency (i.e., 20 mSv per year for occupational workers and 1 mSv in a year for the public). However, it is shown that if the exposure times for occupational workers were to increase to 'normal' working schedules their MAD would be exceeded at three archaeological sites. Implementation of improved ventilation practices is recommended in those sites to reduce the exposure to occupational workers were their working schedules to be significantly increased. It is also recommended that further monitoring be conducted in the future to verify these results

    Old Egyptian pottery samples have been in-depth microchemically analyzed using laser induced breakdown spectroscopy (LIBS), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) techniques. Samples from two different ancient Islamic eras, Mamluk (1250-1517 AD), Fatimid (969-1169 AD) in addition to samples from the Roman period (30 BC-395 AD) were investigated. LIBS provided the analytical data necessary to study in micrometric steps the depth profiling of various elements in each sample. Common elements such as silicon, calcium, and aluminum relevant to the originally manufactured and processed clay, showed up in all the investigated samples. EDX and XRD techniques that have been used in the present work provided important chemical insight about the structure of the samples. The obtained analytical results demonstrated the possibility of using LIBS technique in performing in situ spectrochemical analysis of archaeological pottery. This leads to fast in-depth spatial characterization of the samples in the micron range with nearly invisible surface destructive effects. There is no doubt that this can help in restoration and conservation of such precious objects.

    The second Egyptian research reactor ET-RR-2 went critical on the 27th of November 1997. The National Center of Nuclear Safety and Radiation Control (NCNSRC) has the responsibility of the evaluation and assessment of the safety of this reactor. The purpose of this paper is to present an approach to optimization of the fuel element plate.For an efficient search through the solution space we use a multi objective genetic algorithm which allows us to identify a set of Pareto optimal solutions providing the decision maker with the complete spectrum of optimal solutions with respect to the various targets. The aim of this paper is to propose a new approach for optimizing the fuel element plate in the reactor. The fuel element plate is designed with a view to improve reliability and lifetime and it is one of the most important elements during the shut down. In this present paper, we present a conceptual design approach for fuel element plate, in conjunction with a genetic algorithm to obtain a fuel plate that maximizes a fitness value to optimize the safety design of the fuel plate.
