    Full Text Available Background and Aim. Trace elements and vitamins play a vital role in human body to perform its function properly. Thalassemic patients are at risk of micronutrient deficiency. This study estimated levels of vitamins A, C, E, B12, folic acid, total homocysteine (tHcy, and methylmalonic acid (MMA along with trace elements, zinc, copper, and selenium in Beta-thalassemia-major patients. Methods. This study included 108 patients with Beta-thalassemia-major and 60 age and sex matched healthy children. Serum levels of vitamin A, E, C, tHcy, and MMA were estimated by high pressure liquid chromatography while serum levels of folic acid and B12 were estimated by thin layer chromatography. Serum zinc, copper, and selenium were determined by atomic absorption spectrometry. Results. There was a significant decrease of vitamins A, C, E, and B12 and trace elements zinc, copper, and selenium in thalassemic patients as compared to controls. tHcy and MMA were significantly elevated in patients. No significant correlations were found between the serum levels of the studied vitamins and trace elements as regards age, frequency of transfusion, duration of transfusion, and serum ferritin. Conclusion. The level of various nutritional biomarkers (vitamins A, C, E, and B12 and trace elements zinc, copper, selenium was reduced in chronically transfused Egyptian thalassemic patient. These patients should have periodic nutritional evaluation and supplementation. Multicenter studies are highly recommended.

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

    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

    2001-04-01

    The purpose of this study was to explore the relationships among illness knowledge, social support and self-care behavior in adolescents with beta-thalassemia major. The subjects were 58 beta-thalassemia major adolescents recruited from the pediatric hematology outpatient departments of three hospitals in North Taiwan. All data were analyzed by descriptive statistics, one-way ANOVA, t-test, Pearson correlation, and stepwise multiple regression. The results showed that: (1) Scoring in illness knowledge, the best was treatment knowledge, and the worst was the knowledge of complications and symptoms. (2) The result for social support indicated that the family was the major source of support, and that classmates/friends provided the least support for thalassemic adolescents. (3) Scoring in self care behavior, the best was the medical and chelate therapy, and the worst was the management of problems and coping. (4) Individual characteristic differences, including sex, level of education, length of illness, complications of thalassemia, hospitalization due to thalassemic complications and receiving other treatments were correlated with their illness knowledge, social support or self-care behavior. (5) Illness knowledge, social support which were positively correlated with self-care behavior. (6) 50.0% of the variance in self-care behavior can be explained by emotional support from family, general knowledge of thalassemia, treatment knowledge and appraisal support from family. These findings could provide referential material for nursing research and nursing practice. PMID:11548457

  9. Frequency of hepatitis B and hepatitis C in multi - transfused beta thalassemia major patients

    To determine the frequency of hepatitis B and C virus infection among children with beta thalassemia major registered at Military Hospital Rawalpindi. Children attending Thalassemia Centre Military Hospital Rawalpindi for regular blood transfusion were registered. They belonged to different ethnic groups and came from different parts of the country. Their demographic data was recorded, detailed history taken and physical examination was carried out. Their serum samples were tested for hepatitis B surface antigen and anti HCV antibody assay with third generation commercial ELISA method. During the study; 141 patients of beta thalassemia major were screened. Out of them 50 patients (35.5% ,95% confidence interval 27.8-43.5)w ere found hepatitis C virus antibody positive and 1 patient (0.7 %) hepatitis B surface antigen positive. One patient (0.7%) had both hepatitis B and C virus infection. Mean age of hepatitis C infected patients was 10.4+3.85y ears (range 2-16 years). Mean age of uninfected patients was 6.1 + 3.59 years. (p value 0.000) In addition, the results indicate that higher prevalence of anti-HCV was significantly associated with longer duration of transfusion (p value <0.003). In spite of the fact that screened blood is used for transfusions, still a large number of patients have been found infected with hepatitis C. Therefore more accurate techniques are required for screening of blood to prevent transfusion associated transmission. (author)

  10. Hypoparathyroidism and intracerebral calcification in patients with beta-thalassemia major

    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.

  12. Bone metabolism and mineral density in patients with beta-thalassemia major

    To evaluate bone metabolism in patients with beta-thalassemia major and to determine the factors associated with the development of osteoporosis. We studied 25 patients with thalassemia major with a mean age of 18.4 years (rang 5-31), age and gender matched 24 healthy controls who were attending the outpatient physical medicine and rehabilitation clinic of Akdeniz University Hospital between January 2004 and March 2004 in Turkey. Bone mineral density (BMD) of lumbar spine (L-1-L4) and proximal femur were determined using dual x-ray absorptiometry (DXA). Venous blood samples were obtained for determination of blood cell count and markers of bone formation and resorption. The BMD values, both at lumbar and femoral neck levels were significantly lower in patients compared to controls. Serum N-telopeptide level was slightly higher, whereas osteocalcin was slightly lower in patients, however, the values were not statistically significant. Plasma levels of insulin like growth factor-1 (IGF-I) and insulin like growth factor for binding protein-3 (IGFBP-3) were significantly lower in patients. Also, serum levels of estradiol and progesterone in females, luteinizing, hormone and follicle-stimulating hormone in both genders were significantly lower in patients. Serum levels of free testosterone and total testosterone were lower in patients, but not statistically significant. Patients also had significantly higher serum phosphorous levels and lower serum calcitonin levels compared to controls. The BMD is decreased in thalassemic patients. Growth retardation, growth hormone/IGF-I/IGFP-3 axis dysfunction, gonadal dysfunction and hypothalomo-pituitary-gonadal axis dysfunction may be responsible for the development of osteoporosis in the patients with beta-thalassemia major.

    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 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.

    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.)

    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.

    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

    Objectives: There is a need to remove excess iron with iron chelation therapy (ICT) to avoid the serious clinical sequelae associated with iron overload in patients with beta thalassemia major (BTM) and sickle cell anemia (SCA). Due to the effects of the diseases and their treatments, ICT is still a major reason for unsatisfactory compliance. The aim of this single-center observational study was to evaluate the quality of life, clinical effectiveness, and satisfaction in pediatric and adult p...

    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.

    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.)

    2010-05-01

    Full Text Available Abstract 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

    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 < 0.01 and r > - 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.)

  11. Cord Compression due to Extramedullary Hematopoiesis in an Adolescent with Known Beta Thalassemia Major

    Alan COHLER

    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.

    1981-06-01

    Patients with thalassemia major suffer frequent and serious infections, especially after splenectomy. To explore the basis for this susceptibility, we examined activity of the complement system in sera from 24 patients. All sera had normal or increased activity of the classic complement pathway. However, six of the 24 (three with and three without splenectomy) had abnormal alternative pathway function, and mean alternative pathway activity was significantly decreased in both splenectomized and nonsplenectomized patients. Mean concentrations of C3, factor B, properdin, and immunoglobulins were normal. Defective alternative pathway function, especially in conjunction with asplenia, could contribute to the propensity to infection that exists in thalassemia. PMID:6908998

    1978-07-01

    Total hemolytic complement activity (CH50), immuno-electrophoretic conversion of Factor B (C3PA), and of C3 were studied in 16 patients with sickle cell disease in a steady state, eight patients in crisis, and ten patients with β-thalassemia major anemia maintained on a constant transfusion regimen. Patients with sickle cell disease in a steady state have moderatley 56 (percent) depressed conversion of Factor B in addition to markedly decreased conversion of C3 in four of ten patients. One of the three sickle cell patients and two of the four thalassemia patients with low C3 conversion levels have died subsequent to the studies. The combination of chronically decreased Factor B conversion in the face of markedly decreased C3 conversion may make these patients occasionally vulnerable to overwhelming infection analagous to the situation seen in postsplenectomy cases.

  15. Antioxidant status in beta thalassemia major: A single-center study

    Faiza Waseem

    2011-01-01

    Full Text Available Background: Homozygous β thalassemia may lead to a marked reduction or absence of normal β chain production and accumulation of unpaired alpha-globin chains. A crucial component in the oxidant susceptibility of the thalassemic RBC is the release of heme and iron from the excessive, unpaired α-globin chains. This release can initiate self-amplifying redox reactions, which deplete the cellular reduction potential (e.g., GSH, oxidize additional hemoglobin and accelerate RBC destruction. Furthermore, β-thalassemia patients are under continuous blood transfusion, which, although life-saving, leads to an iron overload with a resultant increase in non-transferrin-bound iron that may cause greater tissue toxicity than iron in other forms. Iron-induced oxidative stress is known to be one of the most important factors determining cell injury in thalassemic patients. Therefore, we designed this study to obtain a comprehensive picture of the iron overload, antioxidant status and cell damage in β thalassemia major patients undergoing regular blood transfusion. Materials and Methods: A total of 48 diagnosed patients of β thalassemia major and 30 age- and sex-matched healthy subjects were included in the study. Estimation of hemoglobin, hematocrit, glutathione peroxidase (GPX, superoxide dismutase (SOD,vitamin E, serum ferritin, total and direct bilirubin, AST and ALT was carried out. Results: The levels of vitamin E, antioxidant enzymes GPX and SOD were significantly lowered in β thalassemic patients as compared with the control group (P<0.001. Serum total and direct bilirubin, AST and ALT were significantly elevated in thalassemic subjects as compared with the control group, indicating liver cell damage. Conclusion: Thus, our findings indicate that thalassemics are in a state of enhanced oxidative stress and that the administration of selective antioxidants would represent a promising approach toward counteracting oxidative damage and its deleterious

    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.

    From January 1991 to June 2009, 245 children with beta thalassemia major who underwent their first allogeneic HSCT in Turkey and who were followed for a minimum of one yr post-transplantation were enrolled this study. The median age of the patients was 6.6 yr old (range, 1-22 yr). The distribution of Pesaro risk class I, II, and III categories was 41, 130, and 63 children, respectively. The median serum ferritin level was 2203 ng/mL. Eighty-eight patients received bone marrow (BM) stem cells; 137, peripheral blood (PB) stem cells; and 20, cord blood (CB) stem cells. The donors were HLA-matched siblings or parents. Median engraftment times were shorter in PBSCT patients compared with the BMT group (p < 0.001). Grade II-IV acute GvHD was observed in 33 children (13.5%), while cGvHD was observed in 28 patients (12.5%), eight of whom had the extensive form. Thalassemic reconstitution was observed in 43 (17%) of the transplant patients. Post-transplant aplasia occurred in three patients, and the TRM rate was 7.75%. Seventeen patients were lost after 100 days. The thalassemia-free survival and OS rates were 68% (95% CI, 61.8-74.2) and 85.0% (95% CI, 80.2-89.8), respectively. We believe that this study is important because it is the first multicenter national data for children with beta thalassemia major receiving HSCT. PMID:22931438

    Full Text Available Background: Chronic hepatitis C infection used to be one of the most important burdens on patients with transfusion-dependent beta thalassemia major (TDTM. Chronic active hepatitis reduces quality of life, and liver cirrhosis and cancer shorten life expectancy in many cases. Objectives: We compared the characteristics of our patients at the Thalassemia Research Center (TRC regarding hepatitis C infection at two time points. Patients and Methods: A review was conducted in a cohort of 390 TDTM patients with a history of at least one blood transfusion in 2014. Type of treatment protocol for hepatitis C virus (HCV and the number of courses were defined. Descriptive statistics were performed using SPSS software (V16. Results: Screening for HCV started in 1995 at the TRC. Seventy-seven (15% patients were antibody-positive in 1995. Tests for virus detection were not available at the time. Patients have been examined using serum AST, ALT, bilirubin, PT, PTT, and liver biopsy, and 45 were treated using alpha interferon alone. A second liver biopsy was performed at the end of treatment for 21 patients, and a blinded pathologist compared the histology according to the Knodell score. According to normalization of liver enzymes, the treatment was successful (McNemar test, P < 0.02. Based on the Knodell score, 54%, 31%, and 11% had complete, partial, and no response, respectively. A quantitative test for viremia became available thereafter. Thirteen patients who were resistant to alpha interferon have been treated using “Pegasys”™ ± ribavirin. Ten patients responded; however, three have been resistant and are still viremic. Twenty-seven patients received no treatment. Twenty-two (81.4% had negative PCR tests. Five viremic patients refused treatment. A second screening test for HCV antibody was introduced in 2001, and, since then, annual screening for HCV antibody has been performed for all patients. No new case has been found since 2001. During the

    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.

    Background: Thalassemia is the commonest inherited hemoglobinopathy. It is estimated that there are about 45 million carriers of the beta thalassemia gene and about 15000 affected infants are born every year in India, thereby contributing to about 10% of the total thalassemia babies born all over the world. Beta Thalassemia Trait (BTT) is asymptomatic while Beta Thalassemia Major (BTM) presents with severe anemia and requires lifelong blood transfusion, so emphasis must shift from treatment t...

  1. Viral infections in transfusion-dependent patients with beta-thalassemia major: the predominant role of cytomegalovirus.

    Nigro, G; Lionetti, P; Digilio, G; Multari, G; Vania, A; Midulla, M

    1990-01-01

    For 9 months, 38 transfusion-dependent patients with beta-thalassemia, ranging in age from 3.4 to 19.1 years, were observed for serologic evidence of viral infections, by the collection of serial serum samples. Seventy-six age-matched healthy subjects, two for each patient, were followed as controls. Samples taken at the beginning, middle, and end of the study were tested against 18 viral antigens by complement fixation (CF). In addition, tests for antibodies to HIV, Epstein-Barr virus, hepatitis A virus, and markers for hepatitis B virus were performed. When changes in the antibody titer on CF tests (greater than or equal to 2-fold increase or decrease) or persistently high titers (greater than or equal to 64) were revealed, specific enzyme immunoassays (EIAs) for IgM and IgA antibodies were performed concomitant with CF tests in all sera. When symptomatic infections occurred, viral cultures and/or direct detection of antigens were carried out by immunofluorescence methods, EIA, or latex agglutination tests. Thalassemic patients and controls had similar (p greater than 0.05) overall rates of serologically confirmed viral infections (53 versus 132), but the former group had a higher (p less than 0.01) incidence of cytomegalovirus (CMV) infections (9 versus 4). CMV infections were associated in the thalassemic patients with hepatitis (2 cases), lymphadenitis (2 cases), and upper respiratory tract infection (1 case), while the remaining cases of CMV had a subclinical course. Moreover, the thalassemic patients had a lower (p less than 0.01) incidence of symptomatic infections (27 versus 110) than controls. Therefore, this study showed that both symptomatic and subclinical CMV infections may occur often in thalassemic patients, who otherwise have subclinical viral infections at an overall rate similar to that in healthy subjects.

    2001-01-01

    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.

    Background It is generally well-understood that iron-mediated cardiomyopathy is the major complication that can arise from beta thalassemia major (TM). Therefore, early diagnosis, risk stratification, and the effective treatment of beta TM patients are clinically important to optimize long-term positive outcomes. Methods This study included 57 beta TM patients with a mean age of 25 ± 7 years. We determined the serum ferritin level, echocardiography, heart rate recovery (HRR), and cardiac magnetic resonance (CMR) T2* in all patients. CMR T2* findings were categorized as normal myocardium (T2* > 20 ms), and myocardial involvement (T2* ≤ 20 ms). HRR values at 1-5 min (HRR1-5) were recorded; Subsequently. HRR was calculated by subtracting the heart rate at each time point from the heart rate at peak exercise. Results There was a significant negative correlation between the serum ferritin level and the cardiac T2* MRI findings (r = -0.34, p = 0.009). A similar result was found in the negative correlation between serum ferritin and all heart rate recovery values. There was a significant positive correlation between HRR1, HRR2, and HRR3 values, and CMR T2* (T2* heart rate recovery (HRR)1: r = 0.51, p < 0.001; T2* HRR2: r = 0.48, p < 0.001; T2* HRR3: r = 0.47, p < 0.001, respectively). Conclusions The serum ferritin level and echocardiography can be used to predict the presence of myocardial iron load in beta TM patients. Therefore, HRR can be used to screen beta TM patients, and the clinical use of HRR can be a predictive marker for autonomic dysfunction in beta TM patients. PMID:27122954

    Background. Intensive transfusion schedule and iron-chelating therapy prolonged and improved quality of life in patients with β-thalassemia (β-T) major. However, this led to an increased risk of developing impaired glucose tolerance or diabetes. In this study we analyzed variables associated with the occurrence of impaired glucose tolerance or diabetes in patients with β-T major. Methods. 388 Sardinian patients were included. Age, gender, duration of chelation therapy, body mass index, and markers of pancreatic and extrapancreatic autoimmunity were analyzed. Results. Multiple logistic regression analysis showed that anti-thyroid peroxidase (TPO) antibodies (Ab) (OR = 3.36; p = 0.008) and male gender (OR = 1.98; p = 0.025) were significantly associated with glucose impairment, while the other variables were not. Ferritin levels were significantly higher in TPOAb positive compared to TPOAb negative patients (4870 ± 1665 μg/L versus 2922 ± 2773 μg/L; p < 0.0001). Conclusions. In patients with β-T major a progressive damage of insulin-producing cells due to secondary hemosiderosis appears to be the most reasonable mechanism associated with glucose metabolism disorders. The findings need to be confirmed with additional well designed studies to address the question of whether TPOAb may have a role in the management of these patients. PMID:27123460

    While thalassemia major (TM) used to be a prevalent genetic disease in the past, however, (PKU) is quite rare in spite of consanquiness marriage rate of about 40% in the region. Preventive efforts for TM started >20 years ago but neonatal screening for PKU started since 2007. This is the first report of co-existence of thalassemia and PKU in Middle East and in consideration of the prevalence of each genes, this chance association is a very unusual event. We report a case of having PKU and TM

    Thalassemia is a hereditary anemia resulting from defect in hemoglobin production. Beta thalassemia is due to impaired production of beta globin chains, leading to a relative excess of alpha globin chains. The term beta thalassemia minor is used to describe heterozygotes, who carry one normal beta globin allele and one beta thalassemic allele. The vast majority of these patients are asymptomatic. However, a variety of renal tubular abnormalities including hypercalciuria, hypo-magnesemia with ...

    The distribution of phenotypes and gene frequencies of the third component of complement (C3) were studied in 106 beta-thalassemic patients and in 112 carriers of the beta-thalassemia trait. A statistically significant association was found between the C3F gene and homozygous beta-thalassemia. It can be suggested that this association may be related with the high incidence of infections encountered in these patients. PMID:6419525

    1983-01-01

    Homozygous beta-thalassemia intermediate (TI) differs from thalassemia major (TM) in being less severe clinically. Associated alpha-thalassemia could account for the TI phenotype by reducing the alpha/non-alpha chain imbalance. We have analyzed the alpha loci of 9 TI and 11 TM patients by restriction endonuclease mapping. All the TM and 7 of the TI patients have the normal complement of four alpha-globin genes (alpha alpha/alpha alpha). One TI patient has three alpha-globin genes (alpha alpha/-alpha), and another TI patient has five alpha genes (alpha alpha/alpha alpha alpha). PMID:6305827

  10. Comparative evaluation of NESTROFT and RDW as screening tests for beta thalassemia trait in pregnancy

    Full Text Available Background: Thalassemia is the commonest inherited hemoglobinopathy. It is estimated that there are about 45 million carriers of the beta thalassemia gene and about 15000 affected infants are born every year in India, thereby contributing to about 10% of the total thalassemia babies born all over the world. Beta Thalassemia Trait (BTT is asymptomatic while Beta Thalassemia Major (BTM presents with severe anemia and requires lifelong blood transfusion, so emphasis must shift from treatment to screening and offering prenatal counseling to affected parents. Methods: It was a hospital based cross sectional study on 500 antenatal women with microcytic hypochromic anemia with hemoglobin <9 gm% and MCV <80 fl and all these women underwent Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT, High Performance Liquid Chromatography (HPLC and serum ferritin estimation. Results: In our study the sensitivity and specificity of NESTROFT was 93.3% and 95.7% respectively compared to Red cell Distribution Width (RDW with a sensitivity and specificity of 66.6% and 78.9% respectively. Conclusions: For low resource settings like India, screening for beta thalassemia by NESTROFT is a cheaper and more reliable method with a high sensitivity and specificity and can be performed easily by paramedical staff.

  11. Renal tubular dysfunction nephrocalcinosis in a patient with BetaThalassemia Minor

    Thalassemia is a hereditary anemia resulting from defect in hemoglobinproduction. Beta thalassemia is due to impaired production. Beta thalassemiais due to impaired production of beta globin chains, leading to a relativeexcess of alpha globin chains. The term beta thalassemia minor is used todescribe heterozygotes, who carry one normal beta globin and one betathalassemic allele. The vast majority of these patients are asymptomatic.However, a variety of renal tubular abnormalities including hypercaliuria,hypomagnesemia with renal magnesium wasting, decreased tubular absorption ofphosphorous, hypouricemia with renal uric acid wasting, renal glycosuria andtubular proteinuria have been described even in patients with betathalassemia minor. We here in report a 24-year old patient who was found tohave thalassemia minor and nephrocalcinosis with evidence of renal tubulardysfunction. Investigations revealed normal renal function, hypercalciuria,reduced tubular reabsorption of phosphorous, hypomagnesemia and renalmagnesium wasting. Screening for aminoaciduria was found to be negative. Anacid loading test revealed normal urinary acidification. Ultrasonogram of theabdomen revealed nephrocalcinosis and splenomegaly. Detailed work up foranemia showed normal white cell and platelet count while peripheral smearshowed microcytic hypochromic anemia with few target cells. Hemoglobinelectrophoresis revealed hemoglobin A of 92%, hemoglobin A2 of 6.2% andhemoglobin F of 1.8% consistent with beta thalassemia minor. Her parentalscreening was normal. A diagnosis of beta thalassemia minor with renaltubular dysfunction was made and the patient was started on thiazidediuretics to reduce hypercalciuria and advised regular follow-up. (author)

  12. Intracranial Extramedullary Hematopoiesis in Beta-Thalassemia

    Extramedullary hematopoiesis (EMH) represents tumor-like proliferation of hemopoietic tissue which complicates chronic hemoglobinopathy. Intracranial EMH is an extremely rare occurrence. Magnetic resonance imaging (MRI) offers a precise diagnosis. It is essential to distinguish EMH from other extradural central nervous system tumors, because treatment and prognosis are totally different. Herein, we report the imaging findings of beta-thalassemia in a 13-year-old boy complaining of weakness of left side of the body and gait disturbance; CT and MRI revealed an extradural mass in the right temporoparietal region.

  14. EXERCISE STRESS ECHOCARDIOGRAPHY WITH TISSUE DOPPLER IMAGING (TDI DETECTS EARLY SYSTOLIC DYSFUNCTION IN BETA-THALASSEMIA MAJOR PATIENTS WITHOUT CARDIAC IRON OVERLOAD

    Umberto Barbero

    2012-06-01

    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.

  15. Prevalence of hepatosplenomegaly in beta thalassemia minor subjects in Iran

    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 mm3, 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.

    Infectious complications constitute the second most common cause of mortality and a main cause of morbidity in beta-thalassemia. Besides the high risk of blood-borne infections associated with multiple transfusions, the increased susceptibility of these patients to infectious diseases has been attributed to a coexistent immune deficiency. Immune abnormalities have also been held responsible for the frequent occurrence of malignancies in beta-thalassemia, especially leukemia and lymphomas. Recent studies on immune competence in beta-thalassemia have revealed numerous quantitative and functional defects, involving T and B lymphocytes, immunoglobulin production, neutrophils and macrophages, chemotaxis, and phagocytosis, as well as the complement system. Regarding pathogenesis, iron overload, a primary complication of both thalassemia itself and transfusion therapy, is thought to be the main precipitating mechanism, due to the important immunoregulatory properties of iron and its binding proteins; iron excess may derange the immune balance in favor of the growth of infectious organisms. Other factors include multiple transfusions, associated with constant allo-antigenic stimulation, as well as with transmission of immunosuppressive viruses; splenectomy, resulting in increased susceptibility to infections by encapsulated bacteria and to immune system modifications; low levels of zinc, another immune regulator; iron chelation therapy, which predisposes to serious infections by yersinia species; and the circulation of abnormal native thalassemic erythrocytes, forming another permanent immune stimulus. Thus surveillance for infections in patients with beta-thalassemia is crucial, while further studies are warranted on immune function abnormalities and the implicated mechanisms. PMID:12552254

    1975-01-01

    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: Cardiac iron toxicity is the leading cause of death among  β-halassaemia major (TM  patients.  Once  heart failure becomes overt , it will be  difficult to reverse . Objectives: To investigate non overt cardiac dysfunctions  in TM patients using  pulsed wave Tissue Doppler  Imaging (TD I and its relation to the iron overload and brain natruritic peptide (BNP. Methods: Thorough  clinical , conventional echo and  pulsed  wave TDI  parameters were compared between  asymtomatic 25 β-TM  patients  and 20 age and gender matched individuals. Serum ferritin and plasma BNP  levels were assayed by  ELISA .  Results: TM patients had significant higher mitral inflow early diastolic (E wave and  non significant other conventional echo  parameters. Pulsed wave TDI revealed systolic and diastolic dysfunctions in the form of significant higher  isovolumetric contraction time (ICT , ejection time ( E T and  isovolumetric relaxation time (IRT with significantly lower  mitral annulus  early diastolic velocity E` (12.07 ±2.06 vs 15.04±2.65 ,P= 0.003  in patients compared to  controls. Plasma BNP was higher in patients compared to the controls.  Plasma BNP and serum ferritin had significant correlation with each other and with pulsed wave conventional and TDI indices of systolic and diastolic functions.  Patients with E/E` ≥ 8 had  significant higher  serum ferritin  and plasma BNP levels compared to those with E/E` ratio < 8 without difference in Hb levels .Conclusion:  Pulsed wave TDI  is an  important diagnostic tool for latent cardiac dysfunction in iron loaded TM patients and is related to iron overload and BNP .

    Full Text Available Background: Both insulin deficiency and resistance are reported in patients with β-thalassemia major (BTM. The use of continuous blood glucose monitoring (CGM, among the different methods for early detection of glycemic abnormalities, has not been studied thoroughly in these adolescents. Materials and Methods: To assess the oralglucose tolerance (OGT and 72-h continuous glucose concentration by the continuous glucose monitoring system (CGMS and calculate homeostatic model assessment (HOMA, and the quantitative insulin sensitivity check index (QUICKI was conducted in 16 adolescents with BTM who were receiving regular blood transfusions every 2-4 weeks and iron-chelation therapy since early childhood. Results: Sixteen adolescents with BTM (age: 19.75 ± 3 years were investigated. Using OGTT, (25% had impaired fasting blood (plasma glucose concentration (BG (>5.6 mmol/L. 2-h after the glucose load, one of them had BG = 16.2 mmol/L (diabetic and two had impaired glucose tolerance (IGT (BG > 7.8 and 11.1 mmol/L and 9 with IGT (56%. HOMA and QUICKI revealed levels 0.33 (0.36 ± 0.03, respectively, ruling out significant insulin resistance in these adolescents. There was a significant negative correlation between the β-cell function (B% on one hand and the fasting and the 2-h BG (r=−0.6, and − 0.48, P < 0.01, respectively on the other hand. Neither fasting serum insulin nor c-peptide concentrations were correlated with fasting BG or ferritin levels. The average and maximum blood glucose levels during CGM were significantly correlated with the fasting BG (r = 0.68 and 0.39, respectively, with P < 0.01 and with the BG at 2-hour after oral glucose intake (r = 0.87 and 0.86 respectively, with P < 0.001. Ferritin concentrations were correlated with the fasting BG and the 2-h blood glucose levels in the OGTT (r = 0.52, and r = 0.43, respectively, P < 0.01 as well as with the average BG recorded by CGM (r = 0.75, P < 0.01.

    Patients and Methods: This study was conducted on 40 children with beta thalassemia major under follow-up at Hematology Unit, Pediatric Department, Tanta University Hospital having serum ferritin level more than 1000 ng/ml and was divided in two groups. Group IA: Received oral Deferasirox (Exjade and silymarin for 6 months. Group IB: Received oral Deferasirox (Exjade and placebo for 6 months and 20 healthy children serving as a control group in the period between April 2011 and August 2012 and was performed after approval from research ethical committee center in Tanta University Hospital and obtaining an informed written parental consent from all participants in this research. Results: Serum ferritin levels were markedly decreased in group IA cases compared with group IB (P= 0.001. Conclusion: From this study we concluded that, silymarin in combination with Exjade can be safely used in treatment of iron-loaded thalassemic patients as it showed good iron chelation with no sign of toxicity. Recommendations: Extensive multicenter studies in large number of patients with longer duration of follow up and more advanced methods of assessment of iron status is recommended to clarify the exact role of silymarin in reduction of iron over load in children with beta thalassemia.

    The parameters of humeral immunity and of the aggregation function of blood platelets were comparatively analyzed in 11 healthy and 26 children with beta-thalassemia; 18 of them had beta-thalassemia of the homozygous type (spleen was extracted in 8 children, and it remained intact in 10 children). It was demonstrated that there was an increased quantity of antibodies to blood platelets and an increased quantity of large, medium-size and small circulating immune complexes in patients with beta-thalassemia and especially in those, who did not undergo splenectomy; there was also an increased quantity of immunoglobulins of classes A, M, and G, a reduced total activity of the complement and a high parameter of the degree of endogenous intoxication, i.e. the content of medium-size molecular peptides. The mentioned disorders were accompanied by worsened aggregation abilities of blood platelets and by their increased disaggregation. Finally, insignificant changes were detected in patients with beta-thalassemia of the heterozygous type. PMID:12715396

    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).

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

    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)

    Wong, C.; Antonarakis, S E; Goff, S C; Orkin, S H; Boehm, C. D.; Kazazian, H H

    1986-01-01

    Seven beta-thalassemia genes were characterized after they were identified as candidates for previously undescribed mutations based upon the close association of DNA polymorphism haplotypes in the beta-globin gene cluster with specific ethnic mutations. The molecular defect in four of these genes was identical, a frameshift deletion of four nucleotides (-CTTT) within codons 41 and 42. This gene represents a common Southeast Asian mutation shared by a Laotian beta-thalassemia gene, [framework ...

  8. Identification of the multiple beta-thalassemia mutations by denaturing gradient gel electrophoresis.

    Cai, S P; Kan, Y W

    1990-01-01

    We used denaturing gradient gel electrophoresis to detect the beta-thalassemia mutations in the Chinese population. By amplifying the beta-globin gene in four separate fragments and electrophoresing the amplified DNA in two gels, we were able to distinguish all the 12 known mutations on the basis of the mobility of the homoduplexes and heteroduplexes. We conclude that denaturing gradient gel electrophoresis offers a nonradioactive means of detecting multiple mutations in genetic disorders.

    {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.

  10. Rare association between two genetic conditions: turner syndrome and beta thalassemia minor

    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.

  11. Infusion of Autologous Retrodifferentiated Stem Cells into Patients with Beta-Thalassemia

    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

    The authors report a case, not described so far in literature, of an association of HbJ-Broussais [alpha (90 (PG2) lys-->asn beta 2] with beta + thalassemia in a young girl born of Italian father and Breton mother. This association is clinically silent. Biochemistry revealed, besides HbA, the presence of HbJ-Broussais in the proportion of 19.4% and HbA2 value of 3.9%. These percentages, slightly lower than expected, are explained. A familial study is presented. PMID:9092311

  15. Approaches to management of beta-thalassemia intermedia

    Joseph E. Maakaron

    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.

    2007-11-01

    Thalassemias and sickle cell anemia (SCA) are common disease in Turkey. To determine the prevalence of beta-thalassemia and SCA traits in Konya urban area of Turkey, all couples applied for marriage procedures were screened. Screening tests included complete blood count and quantitation of hemoglobin for both partners. The subjects were considered to have the beta-thalassemia trait if they had a mean corpuscular volume of less than 80 fL and/or a mean corpuscular hemoglobin level of less than 27 pg and a hemoglobin A2 level of more than 3.2% or a hemoglobin F level of more than 2%. Subjects were considered to have an SCA trait if they were positive for sickle hemoglobin. During the study, premarital screening of hemoglobinopathies was evaluated retrospectively in 72,918 subjects; the thalassemia trait was detected in 1465 subjects (2%), and the SCA trait was detected in 37 subjects (0.05%). Of the carriers of the beta-thalassemia trait, 820 (56%) people had high hemoglobin A2, 513 (35%) people had high hemoglobin F, and 132 (9%) people had both high hemoglobin F and hemoglobin A2. Our results are very similar to Turkey's beta-thalassemia and SCA trait averages. PMID:17984699

  17. Identification of three rare beta-thalassemia mutations in the Pakistani population.

    Khan, S N; Riazuddin, S; Galanello, R

    2000-02-01

    Three rare beta-thalassemia mutations, not reported previously in Asian Indians or the Pakistani population, were identified by single strand conformation polymorphism analysis followed by direct sequencing. Two mutations, IVS-II-848 (C-->A) and initiation codon (ATG-->ACG), were found in the homozygous condition in patients belonging to Balochi and Sindhi ethnic groups of Pakistan, together with heterozygous and homozygous alpha(-3.7) deletions, respectively. A frameshift mutation at codon 44 (-C) was identified in a patient belonging to the Gujrati ethnic group together with IVS-I-1 (G-->T) and a normal complement of four a-globin genes. Haplotype analysis was performed to identify the chromosomal background associated with these mutations, and for tracing the origin and spread of these mutations. PMID:10722111

    2002-11-01

    The purpose of the present study was to identify noninvasive methods to evaluate the severity of iron overload in transfusion-dependent beta-thalassemia and the efficiency of intensive intravenous therapy as an additional tool for the treatment of iron-overloaded patients. Iron overload was evaluated for 26 beta-thalassemia homozygous patients, and 14 of them were submitted to intensive chelation therapy with high doses of intravenous deferoxamine (DF). Patients were classified into six groups of increasing clinical severity and were divided into compliant and non-compliant patients depending on their adherence to chronic chelation treatment. Several methods were used as indicators of iron overload. Total gain of transfusion iron, plasma ferritin, and urinary iron excretion in response to 20 to 60 mg/day subcutaneous DF for 8 to 12 h daily are useful to identify iron overload; however, urinary iron excretion in response to 9 g intravenous DF over 24 h and the increase of urinary iron excretion induced by high doses of the chelator are more reliable to identify different degrees of iron overload because of their correlation with the clinical grades of secondary hemochromatosis and the significant differences observed between the groups of compliant and non-compliant patients. Finally, the use of 3-9 g intravenous DF for 6-12 days led to a urinary iron excretion corresponding to 4.1 to 22.4% of the annual transfusion iron gain. Therefore, continuous intravenous DF at high doses may be an additional treatment for these patients, as a complement to the regular subcutaneous infusion at home, but requires individual planning and close monitoring of adverse reactions.

  20. Regional and ethnic distribution of beta thalassemia mutations and effect of consanguinity in patients referred for prenatal diagnosis

    To determine the regional and ethnic distribution of beta thalassemia mutation and the effect of consanguinity in patients referred for prenatal diagnosis of beta b-thalassemia and to target the high risk population for screening. 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)

    2011-01-01

    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.

  10. Cell and Gene Therapy for the Beta-Thalassemias: Advances and Prospects.

    Mansilla-Soto, Jorge; Riviere, Isabelle; Boulad, Farid; Sadelain, Michel

    2016-04-01

    The beta-thalassemias are inherited anemias caused by mutations that severely reduce or abolish expression of the beta-globin gene. Like sickle cell disease, a related beta-globin gene disorder, they are ideal candidates for performing a genetic correction in patient hematopoietic stem cells (HSCs). The most advanced approach utilizes complex lentiviral vectors encoding the human β-globin gene, as first reported by May et al. in 2000. Considerable progress toward the clinical implementation of this approach has been made in the past five years, based on effective CD34+ cell mobilization and improved lentiviral vector manufacturing. Four trials have been initiated in the United States and Europe. Of 16 evaluable subjects, 6 have achieved transfusion independence. One of them developed a durable clonal expansion, which regressed after several years without transformation. Although globin lentiviral vectors have so far proven to be safe, this occurrence suggests that powerful insulators with robust enhancer-blocking activity will further enhance this approach. The combined discovery of Bcl11a-mediated γ-globin gene silencing and advances in gene editing are the foundations for another gene therapy approach, which aims to reactivate fetal hemoglobin (HbF) production. Its clinical translation will hinge on the safety and efficiency of gene targeting in true HSCs and the induction of sufficient levels of HbF to achieve transfusion independence. Altogether, the progress achieved over the past 15 years bodes well for finding a genetic cure for severe globin disorders in the next decade. PMID:27021486

    2009-09-01

    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.

    Full Text Available Abstract Background The combination of transfusion and chelation therapy has dramatically extended the life expectancy of thalassemic patients. The main objective of this study is to determine the prevalence of prominent thalassemia complications. Methods Two hundred twenty patients entered the study. Physicians collected demographic and anthropometric data and the history of therapies as well as menstrual histories. Patients have been examined to determine their pubertal status. Serum levels of 25(OH D, calcium, phosphate, iPTH were measured. Thyroid function was assessed by T3, T4 and TSH. Zinc and copper in serum were determined by flame atomic absorption spectrophotometry. Bone mineral density (BMD measurements at lumbar and femoral regions have been done using dual x-ray absorptiometry. The dietary calcium, zinc and copper intakes were estimated by food-frequency questionnaires. Results Short stature was seen in 39.3% of our patients. Hypogonadism was seen in 22.9% of boys and 12.2% of girls. Hypoparathyroidism and primary hypothyroidism was present in 7.6% and 7.7% of the patients. About 13 % of patients had more than one endocrine complication with mean serum ferritin of 1678 ± 955 micrograms/lit. Prevalence of lumbar osteoporosis and osteopenia were 50.7% and 39.4%. Femoral osteoporosis and osteopenia were present in 10.8% and 36.9% of the patients. Lumbar BMD abnormalities were associated with duration of chelation therapy. Low serum zinc and copper was observed in 79.6% and 68% of the study population respectively. Serum zinc showed significant association with lumbar but not femoral BMD. In 37.2% of patients serum levels of 25(OH D below 23 nmol/l were detected. Conclusion High prevalence of complications among our thalassemics signifies the importance of more detailed studies along with therapeutic interventions.

  13. Peripheral Blood stem cell transplantation in children with Beta-thalassemia major

    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)

  14. Sehgal index: A new index and its comparison with other complete blood count-based indices for screening of beta thalassemia trait in a tertiary care hospital

    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.

  15. Perfil de beta talassemia heterozigota obtido a partir de análise data mining em banco de dados The profile of beta thalassemia obtained by data mining analysis in a database

    2010-02-01

    Full Text Available Variations in the phenotypic expression of heterozygous beta thalassemia reflect the formation of different populations. To better understand the profile of heterozygous beta-thalassemia of the Brazilian population, we aimed at establishing parameters to direct the diagnosis of carriers and calculate the frequency from information stored in an electronic database. Using a Data Mining tool, we evaluated information on 10,960 blood samples deposited in a relational database. Over the years, improved diagnostic technology has facilitated the elucidation of suspected beta thalassemia heterozygote cases with an average frequency of 3.5% of referred cases. We also found that the Brazilian beta thalassemia trait has classic increases of Hb A2 and Hb F (60%, mainly caused by mutations in beta zero thalassemia, especially in the southeast of the country.

    Full Text Available Background: Oxidative stress in children with β-thalassemia may contribute to shortened life span of erythrocytes and endocrinal abnormalities. Aim: This study was aimed to evaluate glucose homeostasis in Egyptian children and adolescents with β-thalassemia major and its relation to oxidative stress. Materials and Methods: Sixty children and adolescents with β-thalassemia major were studied in comparison to 30 healthy age and sex-matched subjects. Detailed medical history, thorough clinical examination, and laboratory assessment of oral glucose tolerance test (OGTT, serum ferritin, alanine transferase (ALT, fasting insulin levels, plasma malondialdehyde (MDA as oxidant marker and serum total antioxidants capacity (TAC were performed. Patients were divided into two groups according to the presence of abnormal OGTT. Results: The prevalence of diabetes was 5% (3 of 60 and impaired glucose tolerance test (IGT was 8% (5 of 60. Fasting blood glucose, 2-hour post-load plasma glucose, serum ferritin, ALT, fasting insulin level, homeostatic model assessment for insulin resistance index (HOMA-IR and MDA levels were significantly elevated while TAC level was significantly decreased in thalassemic patients compared with healthy controls (P < 0.001 for each. The difference was more evident in patients with abnormal OGTT than those with normal oral glucose tolerance (P < 0.001 for each. We also observed that thalassemic patients not receiving or on irregular chelation therapy had significantly higher fasting, 2-h post-load plasma glucose, serum ferritin, ALT, fasting insulin, HOMA-IR, oxidative stress markers OSI and MDA levels and significantly lower TAC compared with either those on regular chelation or controls. HOMA-IR was positively correlated with age, serum ferritin, ALT, MDA, and negatively correlated with TAC. Conclusions: The development of abnormal glucose tolerance in Egyptian children and adolescents with β--thalassemia is associated with

  19. Electrocardiographic Presentation, Cardiac Arrhythmias, and Their Management in β-Thalassemia Major Patients.

    Russo, Vincenzo; Rago, Anna; Papa, Andrea Antonio; Nigro, Gerardo

    2016-07-01

    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.

    1996-10-01

    Programs for education, screening, and counseling of senior-high-school students, in populations at high risk for Tay-Sachs and beta-thalassemia diseases, have existed for >20 years in Montreal. 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

  1. Factor V G1691A (Leiden is a major etiological factor in Egyptian Budd-Chiari syndrome patients

    Tawhida Y. Abdel Ghaffar

    2011-12-01

    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.

  2. Insulin-like growth factor-1 levels in children with Beta-thalassemia minor

    2008-09-01

    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.

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

    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 Background: Niemann-Pick disease and β-thalassemia are distinct conditions with specific clinical and morphological manifestations. β-thalassemia is the most common inherited blood disorder in Iran whereas Niemann-Pick disease, a lysosomal storage disorder, is rarely found in this country.Case Presentation: This 5-month old girl, a known case of β-thalassemia major was hospitalized for failure to thrive and hepathosplenomegaly. Because of unusual splenomegaly and liver enzymes disturbance that was not compatible with the first diagnosis, further evaluation revealed cherry red spot and high lipid profile suggestive of lysosomal storage disease. Foamy cells in the bone marrow and low activity of the specific enzyme led to the diagnosis of Niemann-Pick disease.Conclusion: This unique case illustrates the importance of looking for a second pathological condition in a patient whose clinical profile does not support the first diagnosis in its entirety.

    Pagano, L; Lacerra, G; Camardella, L; De Angioletti, M; Fioretti, G; Maglione, G; de Bonis, C; Guarino, E; Viola, A; Cutolo, R

    1991-12-01

    A novel beta-chain, beta 126(H4)Val----Gly, electrophoretically silent, was detected by reverse-phase high performance liquid chromatography in three unrelated families from Naples (Southern Italy) and accounted for about 30% of the total beta-chains. The amino acid substitution was detected by HPLC fingerprint. The eight heterozygous patients showed hematologic and biosynthetic alterations of mild beta-thalassemia type. The hemoglobin variant showed abnormal stability features. It was unstable in the heat stability and isopropanol precipitation tests, but did not cause a hemolytic syndrome in vivo and was stable in a time-course experiment of biosynthesis in vitro. DNA polymerase chain reaction direct sequencing of the mutated gene from 135 nt upstream of the cap site to 106 nt downstream of the polyadenylation site showed only the beta 126 GTG----GGG mutation, which was confirmed in the other patients by allele-specific oligonucleotide hybridization. The mutation was found to be associated with a type II beta-globin framework and restriction fragment length polymorphism haplotype V. The novel variant was named hemoglobin Neapolis. PMID:1954392

  12. 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.

    Full Text Available 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.

  14. Comparing prevalence of Iron Deficiency Anemia and Beta Thalassemia Trait in microcytic and non-microcytic blood donors: suggested algorithm for donor screening

    Tiwari Aseem

    2009-01-01

    Full Text Available Background: The prevalence of microcytosis in donors and Iron Deficiency Anemia (IDA and Beta-Thalassemia trait (BTT in microcytic and non-microcytic donors has not been studied in India. The present study aims at finding the same. Materials and Methods: Initially 925 donor samples were evaluated on cell-counter. Of these, 50 were found to be microcytic. These were subjected to Ferritin and HbA2 determination. Subsequently, an additional 51, age-and-sex matched non-microcytic donor samples were selected to serve as controls. These were subjected to the same tests. Results: The prevalence of microcytosis was 5.4% (50/925. Among the microcytic donors, 52% were IDA, 36% BTT, 8% both, and 4% none. In case of non-microcytic donors 29.4% were IDA, 3.9% BTT, and 66.7% none. Conclusions: The study revealed a high prevalence of IDA and BTT in blood donors and a higher probability of finding these in the microcytic samples. This prompted authors to suggest an algorithm for screening of blood donors for IDA and BTT. The algorithm recommends doing an hemogram on all donor samples, routinely. Ferritin could be done only in microcytic samples. At levels lower than15 ng/ml, it is diagnosed as IDA, and therefore, HPLC is performed only for non-IDA samples with Ferritin levels higher than 15 ng/ml. By employing this algorithm, a substantial number of IDA and BTT could be diagnosed while keeping the number of Ferritin tests small and the number of HPLC tests even smaller and thus making it cost efficient.

  17. Community genetics and health approaches for bringing awareness in tribals for the prevention of beta-thalassemia in India

    Ranbir S. Balgir

    2011-08-01

    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.

    2012-11-01

    Full Text Available Nonsense-mediated mRNA decay (NMD is a surveillance system to prevent the synthesis of non-functional proteins. In β-thalassemia, NMD may have a role in clinical outcome. An example of premature translation stop codons appearing for the first time is the β-globin cd39 mutation; when homozygous, this results in a severe phenotype. The aim of this study was to determine whether the homozygous nonsense cd39 may have a milder phenotype in comparison with IVS1,nt110/cd39 genotype. Genotypes have been identified from a cohort of 568 patients affected by β-thalassemia. These genotypes were compared with those found in 577 affected fetuses detected among 2292 prenatal diagnoses. The nine most common genotypes, each with an incidence rate of 1.5% or over, and together accounting for 80% of genotype frequencies, underwent statistical analysis. Genotype prevalence was calculated within the overall group. Results are expressed as proportions with 95% confidence intervals; P≤0.05 was considered statistically significant. A binomial distribution was assumed for each group; z-tests were used to compare genotype frequencies observed in the patient group with frequencies in the affected fetus group. In the absence of selecting factors, prevalence of these two genotypes was compared between a cohort of 568 β-thalassemia patients (PTS and 577 affected fetuses (FOET detected during the same period. IVS1,nt110/cd39 was significantly more prevalent in FOET than PTS (P<0.0001, while there was no significant difference in prevalence of cd39/cd39 in FOET compared with PTS (P=0.524. These results suggest a cd39 genotype NMD mechanism may be associated with improved clinical outcomes in thalassemia major. 无义介导的mRNA 降解(NMD) 是一种预防非功能性蛋白质合成的监控系统。在β地中海贫血中,NMD可能对临床结果有影响。第一次出现的过早终止密码子(PTC)为β珠蛋白cd39突变;若为纯合

  19. MRI of the liver and the pituitary gland in patients with {beta}-thalassemia major: Does hepatic siderosis predict pituitary iron deposition?

    Argyropoulou, Maria I.; Efremidis, Stavros C. [Department of Radiology, Medical School, University of Ioannina, 45110 Ioannina (Greece); Kiortsis, Dimitrios N. [Laboratory of Physiology, Medical School, University of Ioannina, 45110 Ioannina (Greece)

    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.)

  1. Impact of Genetic Polymorphism of methylenetetrahydrofolate reductase C677T on Development of Hyperhomocysteinemia and Related Oxidative Changes in Egyptian β-Thalassemia Major Patients.

    Mai A Abd-Elmawla

    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

  3. Multiple transfused thalassemia major: Ocular manifestations in a hospital-based population

    Taneja Rashi

    2010-01-01

    Full Text Available Purpose: To study the ocular manifestations in multiple transfused beta-thalassemia major patients and assess the ocular side-effects of iron chelating agents. Materials and Methods: In this prospective observational study, 45 multiple transfused beta-thalassemia major children between six months and 21 years of age were enrolled and assigned groups according to the treatment regimens suggested. Group A received only blood transfusions, Group B blood transfusions with subcutaneous desferrioxamine, Group C blood transfusions with desferrioxamine and oral deferriprone and Group D blood transfusions with deferriprone. Ocular status at the time of enrolment was documented. Subjects were observed quarterly for one year for changes in ocular status arising due to the disease process and due to iron chelation therapy. Children with hemoglobinopathies other than beta-thalassemia major, congenital ocular anomalies and anemia due to other causes were excluded. Results: Ocular involvement was observed in 58% of patients. Lenticular opacities were the most common ocular finding (44%, followed by decreased visual acuity (33%. An increased occurrence of ocular changes was observed with increase of serum ferritin and serum iron levels as well as with higher number of blood transfusions received. Desferrioxamine seemed to have a protective influence on retinal pigment epithelium (RPE mottling. Occurrence of lenticular opacities and RPE degeneration correlated positively with use of desferrioxamine and deferriprone respectively. Follow-up of patients for one year did not reveal any change in ocular status. Conclusion: Regular ocular examinations can aid in preventing, delaying or ameliorating the ocular complications of thalassemia.

    Thalassemia can lead to severe transfusion-dependent anemia, and it is the most common genetic disorder in Malaysia. This paper aims to determine the prevalence of thalassemia in the Kadazandusuns, the largest indigenous group in Sabah, East Malaysia. α- and β-thalassemia were confirmed in 33.6% and 12.8%, of the individuals studied respectively. The high prevalence of α- and β-thalassemia in the Kadazandusuns indicates that thalassemia screening, genetic counseling, and prenatal diagnosis should be included as part of their healthcare system. This preliminary paper serves as a baseline for further investigations into the health and genetic defects of the major indigenous population in Sabah, East Malaysia. PMID:20871816

    2011-08-01

    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.

    2012-04-01

    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.

    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.

  14. 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.

  16. Study on effectiveness of transfusion program in thalassemia major patients receiving multiple blood transfusions at a transfusion centre in Western India

    Shah Neeraj

    2010-01-01

    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

  17. [Ancient Egyptian Odontology].

    Berghult, B

    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

  20. Thermoluminescence (TL) of Egyptian Blue

    Schvoerer, M.; Delavergne, M.-C.; Chapoulie, R.

    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.

At this stage I would only wish to emphasize the distinction between a) the more ancient version of the "...

  2. Some endocrinal aspects of pancreas in beta thalassemia

    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

  6. The Archaeology of Egyptian Monasticism

    Blanke, Louise

    The study of Egyptian monasticism has traditionally relied heavily on the rich corpus of textual sources, while the archaeological remains have been secondary to our understanding of monastic life.

  7. Radiological assessment of the Egyptian Mediterranean coast

    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. Good agreement was observed with NCRP

  9. Orientation of Egyptian Temples: An Overview

    Belmonte, Juan Antonio

    Archaeoastronomy has never been a favored discipline within Egyptology. As a consequence, important questions such as the orientation of Egyptian temples and the relevance of astronomy in this respect had not been treated with the requisite seriousness and depth. This situation is changing, however, and over the past decade, there have been several serious attempts to perform an extensive analysis of the orientation of Egyptian monuments. The orientations of approximately 400 temples have been measured in the Nile Valley, the Delta, the Oases, and the Sinai, with the aim of providing a clear answer to the question of whether the ancient Egyptian sacred constructions were astronomically aligned or not. This impressive set of data seems to answer this question in the affirmative.

  10. Rare Earth Elements in Egyptian Phosphorites

    I.S. ISMAEL

    2002-01-01

    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.

  12. Classification of sharks in the Egyptian Mediterranean waters using morphological and DNA barcoding approaches.

    Marie Moftah

    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.

  13. ICT BASED TELEMEDICINE FOR THE EGYPTIAN SOCIETY

    Hafez A. Fouad

    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

  18. ANTHROPOMETRIC STUDY OF NASAL INDEX OF EGYPTIANS

    Abdelmonem Awad Hegazy

    2014-12-01

    Full Text Available Background: The nasal index determination is one of the most commonly used anthropometric parameters in classifying human races. There are few reports in medical literature concerning nasal index that specifically address particular Egyptian populations. The objective of this study was to determine the normal parameters of external nose (width, height and nasal index in Egyptians. Methods: The study was conducted randomly on healthy Egyptian subjects of both sexes. Nasal height and width were measured using vernier caliper. Then, nasal index was determined for each subject. The obtained data were subjected to statistical analysis. Results: A total of 290 subjects, 144 males and 146 females, aged 1 month– 65 years, were enrolled in the study. The study showed the existence of sexual dimorphism in nasal morphology, appearing after the age 20 years. The mean nasal index in the investigated adults was 68.01; in males and females was 71.46 and 64.56, respectively. Conclusions: The dominant nasal type in Egyptians was in-between mesorrhine "medium" and leptorrhine "narrow" nose. Forensic and anthropological research, as well as cosmetic and reconstructive surgery may benefit from age- and sex- based data of the study.

  2. Investigating the use of Egyptian blue in Roman Egyptian portraits and panels from Tebtunis, Egypt

    Ganio, Monica; Salvant, Johanna; Williams, Jane; Lee, Lynn; Cossairt, Oliver; Walton, Marc

    2015-11-01

    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.

  3. Contributions of Egyptian Women in Physics (abstract)

    El Nadi, Lotfia

    2009-04-01

    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.

  5. The thermoluminescence (TL) of Egyptian Blue

    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.

  6. Mitochondrial genome sequence of Egyptian swift Rock Pigeon (Columba livia breed Egyptian swift).

    Li, Chun-Hong; Shi, Wei; Shi, Wan-Yu

    2015-06-01

    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. PMID:24438285

  7. The Egyptian Red Sea coastal microbiome: A study revealing differential microbial responses to diverse anthropogenic pollutants.

    2016-07-01

    The Red Sea is considered one of the youngest oceanic systems, with unique physical, geochemical and biological characteristics. Tourism, industrialization, extensive fishing, oil processing and shipping are extensive sources of pollution in the Red Sea. We analyzed the geochemical characteristics and microbial community of sediments along the Egyptian coast of the Red Sea. Our sites mainly included 1) four ports used for shipping aluminum, ilmenite and phosphate; 2) a site previously reported to have suffered extensive oil spills; and 3) a site impacted by tourism. Two major datasets for the sediment of ten Red Sea coastal sites were generated; i) a chemical dataset included measurements of carbon, hydrogen, nitrogen and sulfur, metals and selected semi-volatile oil; and ii) a 16S rRNA Pyrotags bacterial metagenomic dataset. Based on the taxonomic assignments of the 16S rRNA Pyrotags to major bacterial groups, we report 30 taxa constituting an Egyptian Red Sea Coastal Microbiome. Bacteria that degrade hydrocarbons were predominant in the majority of the sites, particularly in two ports where they reached up to 76% of the total identified genera. In contrast, sulfate-reducing and sulfate-oxidizing bacteria dominated two lakes at the expense of other hydrocarbon metabolizers. Despite the reported "Egyptian Red Sea Coastal Microbiome," sites with similar anthropogenic pollutants showed unique microbial community abundances. This suggests that the abundance of a specific bacterial community is an evolutionary mechanism induced in response to selected anthropogenic pollutants. PMID:27179234

  10. Egyptian plant species as new ozone indicators

    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

  3. National Conference on Findings of Egyptian Maternal and Child Health Survey (7-8 September 1992).

    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

Water and soil samples were brought from these locations and subjected to intensive physical, chemical analysis and radiological investigations. The densities of the collected soil samples were found to fall in the region of clay densities (2.30 - 2.70 g/cm 3 ). The particle size distribution analysis, of these soil samples showed values ranging from 128 Μ m to 1303 Μ according to sample site. The collected samples are mainly silicates with variable amounts of the major cations; Ca++, Mg++, Na+, K+ with some other trace elements. For the radiological investigations 238U, 226Ra, 232Th and 40K activity concentrations were resolved by spectroscopy technique. The majority of samples examined in this work showed variable activities of the naturally occurring radionuclides with fairly low levels compared with literature values reported in other countries. The analysis and discussions of the obtained data are thoroughly performed with the use of equations to estimate the radiation doses

  6. Egyptian international labor migration and social processes: toward regional integration.

    Sell, R R

    1988-01-01

    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

  7. General fire protection guidelines for Egyptian nuclear installations

    The purpose of this paper is to establish the regulatory requirements that will provide and ensure fire protection of Egyptian nuclear installations. Two or more classes of occupancy are considered to occur in the same building or structure. Fire protection measures and systems were reviewed for four of the Egyptian nuclear installations. These are Egypt's first research reactor (ET-RR-1) building and systems, hot laboratories buildings and facilities, the building including the AECL type JS-6500 industrial cobalt-60 gamma irradiator ''Egypt's Mega Gamma I'' and Egypt's second research multi-purpose reactor (MPR). A brief review is given about fire incidents in Egypt, and descriptions of the only fire reported at one of the Egyptian nuclear installations over more than 35 years of operating these installations. The study outlines the various aspects of fire protection with a view to define the relevant highlights and scope of an Egyptian guidelines. (author)

    Full Text Available Coccidiosis is a serious protozoal disease of poultry. The identification of Eimeria species has important implications for diagnosis and control as well as for epidemiology. The molecular characterization of Eimeria species infecting Egyptian baladi chickens was investigated.Eimeria species oocysts were harvested from intestines of naturally infected Egyptian baldi chickens. The morphometry characterization of oocysts along with COCCIMORPH software was done. The DNA was extracted initially by freezing and thawing then the prepared samples was subjected to commercial DNA kits. The DNA products were analyzed through conventional polymerase chain reaction by using amplified region (SCAR marker.The PCR results confirmed the presence of 7 Eimeria species in the examined fecal samples of Egyptian baldi breed with their specific ampilicon sizes being E. acervulina (811bp, E. brunette (626bp, E. tenella (539bp, E. maxima (272bp, E. necatrix (200bp, E. mitis (327bp and E. praecopx (354bp. A sequencing of the two most predominant species of Eimeria was done, on E. tenella and E. máxima. Analysis of the obtained sequences revealed high identities 99% between Egyptian isolates and the reference one. Similarly, E. maxima isolated from Egyptian baldi chickens showed 98% nucleotide identities with the reference strain. Only single nucleotide substitution was observed among the Egyptian E. tenella isolates (A181G when compared to the reference one. The Egyptian isolates acquired 4 unique mutations (A68T, C164T, G190A and C227G in compared with the reference sequence.This is the first time to identify the 7 species of Eimeria from Egyptian baladi chickens.

    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 ar...

    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....

  14. Characterization of Egyptian coal from Sinai using Moessbauer spectroscopy

    The presence of iron bearing minerals in coal makes the Moessbauer Spectroscopy (MS) extremely useful for characterization of coals from different localities. In this paper the MS has been applied to characterize Egyptian coal from Sinai (Maghara). The chemical analysis of this coal is given. The MS results showed that pyritic sulphur (pyrite and marcasite) is the only bearing mineral in Egyptian coal. A review is given for the iron bearing minerals in coals from different countries measured by MS. (author)

  15. Spectral signature of Egyptian crude oils

    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

Also detect the method that can attract the consumers to adopt the technique and ensure the success handling of irradiated in egyptian market. One thousand and twenty two poll sheets were collected. 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%

  17. Radiation levels in ancient Egyptian mummies

    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)

    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).

  19. Examination of an Egyptian mummy - stereolithography applied

    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)

  20. Estimates of the effect on hepatic iron of oral deferiprone compared with subcutaneous desferrioxamine for treatment of iron overload in thalassemia major: a systematic review

    Caro J

    2002-11-01

    Full Text Available Abstract Background Beta thalassemia major requires regular blood transfusions and iron chelation to alleviate the harmful accumulation of iron. Evidence on the efficacy and safety of the available agents, desferrioxamine and deferiprone, is derived from small, non-comparative, heterogeneous observational studies. This evidence was reviewed to quantitatively compare the ability of these chelators to reduce hepatic iron. Methods The literature was searched using Medline and all reports addressing the effect of either chelator on hepatic iron were considered. Data were abstracted independently by two investigators. Analyses were performed using reported individual patient data. Hepatic iron concentrations at study end and changes over time were compared using ANCOVA, controlling for initial iron load. Differences in the proportions of patients improving were tested using χ2. Results Eight of 11 reports identified provided patient-level data relating to 30 desferrioxamine- and 68 deferiprone-treated patients. Desferrioxamine was more likely than optimal dose deferiprone to decrease hepatic iron over the average follow-up of 45 months (odds ratio, 19.0, 95% CI, 2.4 to 151.4. The degree of improvement was also larger with desferrioxamine. Conclusions This analysis suggests that desferrioxamine is more effective than deferiprone in lowering hepatic iron. This comparative analysis – despite its limitations – should prove beneficial to physicians faced with the challenge of selecting the optimal treatment for their patients.

  1. Biodiversity of Bacterial Ecosystems in Traditional Egyptian Domiati Cheese▿

    El-Baradei, Gaber; Delacroix-Buchet, Agnès; Ogier, Jean-Claude

    2007-01-01

    Bacterial biodiversity occurring in traditional Egyptian soft Domiati cheese was studied by PCR-temporal temperature gel electrophoresis (TTGE) and PCR-denaturing gradient gel electrophoresis (DGGE). Bands were identified using a reference species database (J.-C. Ogier et al., Appl. Environ. Microbiol. 70:5628-5643, 2004); de novo bands having nonidentified migration patterns were identified by DNA sequencing. Results reveal a novel bacterial profile and extensive bacterial biodiversity in Domiati cheeses, as reflected by the numerous bands present in TTGE and DGGE patterns. The dominant lactic acid bacteria (LAB) identified were as follows: Leuconostoc mesenteroides, Lactococcus garvieae, Aerococcus viridans, Lactobacillus versmoldensis, Pediococcus inopinatus, and Lactococcus lactis. Frequent non-LAB species included numerous coagulase-negative staphylococci, Vibrio spp., Kocuria rhizophila, Kocuria kristinae, Kocuria halotolerans, Arthrobacter spp./Brachybacterium tyrofermentans. This is the first time that the majority of these species has been identified in Domiati cheese. Nearly all the dominant and frequent bacterial species are salt tolerant, and several correspond to known marine bacteria. As Domiati cheese contains 5.4 to 9.5% NaCl, we suggest that these bacteria are likely to have an important role in the ripening process. This first systematic study of the microbial composition of Domiati cheeses reveals great biodiversity and evokes a role for marine bacteria in determining cheese type. PMID:17189434

    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

    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

    2006-06-01

    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

  9. Composition of Egyptian nerolì oil.

    2011-07-01

    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

    2015-01-01

    The aim of the present study was to assess female sexual function in an obese group (250 women) and to compare it with a control group (100 women), among 25-35-year-old uncircumcised Egyptian women, using female sexual function index (FSFI) score. FSFI total score of ⩽ 26.55 was considered diagnostic of Female Sexual Dysfunction (FSD). The percentage of FSD in the obese group was 73.6% while it was 71% in the control group, which was statistically insignificant (P > 0.05). The difference between both groups regarding the total (FSFI) score was insignificant (P > 0.05), but arousal and satisfaction domains scores were significantly lower in the obese group. In the obese group, a strong negative correlation between body mass index and arousal, orgasm and the total FSFI score was found. Women with excessive obesity had the lowest total FSFI score. In the obese group, college graduates had the highest total scores and all domain scores of FSFI followed by high school graduates while the least educated women had the lowest scores and when these subgroups were compared, significant differences were found among them. We conclude that in uncircumcised 25-35-year-old Egyptian women, obesity is not a major detrimental factor for FSD, but it may affect some sexual domains such as arousal and satisfaction, although excessive obesity is associated with FSD. Also, educational and cultural factors may have an impact on perception of sex and pleasure. PMID:26155831

  1. Evaluation of municipal solid waste management in egyptian rural areas.

    El-Messery, Mamdouh A; Ismail, Gaber A; Arafa, Anwaar K

    2009-01-01

    A two years study was conducted to evaluate the solid waste management system in 143 villages representing the Egyptian rural areas. The study covers the legal responsibilities, service availability, environmental impacts, service providers, financial resources, private sector participation and the quality of collection services. According to UN reports more than 55% of Egyptian population lives in rural areas. A drastic change in the consumption pattern altered the quantity and quality of the generated solid wastes from these areas. Poor solid waste management systems are stigmata in most of the Egyptian rural areas. This causes several environmental and health problems. It has been found that solid waste collection services cover only 27% of the surveyed villages, while, the statistics show that 75% of the surveyed villages are formally covered. The service providers are local villager units, private contractors and civil community associations with a percentage share 71%, 24% and 5% respectively. The operated services among these sectors were 25%, 71% and 100% respectively. The share of private sector in solid waste management in rural areas is still very limited as a result of the poverty of these communities and the lack of recyclable materials in their solid waste. It has been found that direct throwing of solid waste on the banks of drains and canals as well as open dumping and uncontrolled burning of solid waste are the common practice in most of the Egyptian rural areas. The available land for landfill is not enough, pitiable designed, defectively constructed and unreliably operated. Although solid waste generated in rural areas has high organic contents, no composting plant was installed. Shortage in financial resources allocated for valorization of solid waste management in the Egyptian rural areas and lower collection fees are the main points of weakness which resulted in poor solid waste management systems. On the other hand, the farmer's participation

    2009-01-01

    Bats are a highly successful, widely distributed group, with considerable variation in placental structure. The Egyptian slit-faced bat Nycteris thebaica is a member of one of the few families with previously undescribed placentation. It was found that, although the interhemal type of the Nycteris...... placenta is endotheliochorial with a single layer of cytotrophoblast, the arborizing pattern of the maternal vessels and especially the extraordinary major placental artery differs from the placenta of the emballonurid bats to which this family is considered to be most closely related. The major placental...... other bat species. The paraplacenta is extensive with abundant fetal vessels underlying cytotrophoblast and syncytial trophoblast layers, fronting on an endometrium that largely lacks uterine epithelial cells but has large decidual cells and is poorly vascularized. The placenta of Nycteris lacks a...

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

    Carpenter JP

    2011-09-01

    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.

    2015-01-01

    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

  6. Striking presence of Egyptian blue identified in a painting by Giovanni Battista Benvenuto from 1524.

    Bredal-Jørgensen, Jørn; Sanyova, Jana; Rask, Vibeke; Sargent, Maria Louise; Therkildsen, Rikke Hoberg

    2011-09-01

    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.

  10. An investigation into the ancient Egyptian cultural influences on the Yorubas of Nigeria

    Jock M. Agai

    2013-01-01

    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 Yoru...

    AIM:To detect the prevalence of anti-HAV IgG antibodies in adult multitransfused beta-thalassemic patients.METHODS:We studied 182 adult beta-thalassemic patients and 209 controls matched for age and sex from the same geographic area,at the same time.Anti-HAV IgG antibodies,viral markers of hepatitis B virus (HBV)and hepatitis C virus (HCV) infection were evaluated.RESULTS:Anti-HAV IgG antibodies were detected more frequently in thalassemic patients(133/182;73.1%)than in healthy controls(38/209;18.2%,P<0.0005).When we retrospectively evaluated the prevalence of anti-HAV IgG antibodies in 176/182(96.7%)thalassemic patients,whose medical history was available for the previous ten years,it was found that 83(47.2%)of them were continuously anti-HAV IgG positive,16(9.1%)acquired anti-HAV IgG antibody during the previous ten years,49 (27.8%) presented anti-HAV positivity intermittently and 28 (15.9%) were anti-HAV negative continuously.CONCLUSION:Multitransfused adult beta-thalassemic patients present higher frequency of anti-HAY IgG antibodies than normal population of the same geographic area.This difference is difficult to explain,but it can be attributed to the higher vulnerability .of thalassemics to HAV infection and to passive transfer of anti-HAV antibodies by blood transfusions.

    Regulation of erythropoiesis is achieved by integration of distinct signals. Among these, macrophages are emerging as erythropoietin-complementary regulators of erythroid development, particularly under stress conditions. We investigated the contribution of macrophages for physiological and pathological conditions of enhanced erythropoiesis. We utilized mouse models of induced anemia, Polycythemia vera and β-thalassemia in which macrophages were chemically depleted. Our data indicate that mac...

    2012-01-01

    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.

    Full Text Available Lorenzo Capretto1, Stefania Mazzitelli2, Eleonora Brognara2, Ilaria Lampronti2, Dario Carugo1, Martyn Hill1, Xunli Zhang1, Roberto Gambari2, Claudio Nastruzzi31Engineering Sciences, University of Southampton, Southampton, UK; 2Department of Biochemistry and Molecular Biology, 3Department of Pharmaceutical Sciences, University of Ferrara, Ferrara, ItalyAbstract: This report shows that the DNA-binding drug, mithramycin, can be efficiently encapsulated in polymeric micelles (PM-MTH, based on Pluronic® block copolymers, by a new microfluidic approach. The effect of different production parameters has been investigated for their effect on PM-MTH characteristics. The compared analysis of PM-MTH produced by microfluidic and conventional bulk mixing procedures revealed that microfluidics provides a useful platform for the production of PM-MTH with improved controllability, reproducibility, smaller size, and polydispersity. Finally, an investigation of the effects of PM-MTH, produced by microfluidic and conventional bulk mixing procedures, on the erythroid differentiation of both human erythroleukemia and human erythroid precursor cells is reported. It is demonstrated that PM-MTH exhibited a slightly lower toxicity and more pronounced differentiative activity when compared to the free drug. In addition, PM-MTH were able to upregulate preferentially γ-globin messenger ribonucleic acid production and to increase fetal hemoglobin (HbF accumulation, the percentage of HbF-containing cells, and their HbF content without stimulating α-globin gene expression, which is responsible for the clinical symptoms of ß-thalassemia. These results represent an important first step toward a potential clinical application, since an increase in HbF could alleviate the symptoms underlying ß-thalassemia and sickle cell anemia. In conclusion, this report suggests that PM-MTH produced by microfluidic approach warrants further evaluation as a potential therapeutic protocol for ß-thalassemia.Keywords: microfluidics, lab-on-a-chip, design of experiments, erythroid differentiation, human erythroid precursor cells

    2009-12-01

    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

  4. The Egyptian Revolution: First Impressions from the Field

    Mohammed A. Bamyeh

    2011-02-01

    Full Text Available Never has a revolution that seemed so lacking in prospects gathered momentum so quickly and so unexpectedly. The Egyptian Revolution, starting on January 25, lacked leadership and possessed little organization; its defining events, on Friday, January 28, occurred on a day when all communication technologies, including all internet and phones, were barred; it took place in a large country known for sedate political life, a very long legacy of authoritarian continuity, and an enviable repressive apparatus consisting of more than 2 million members. But on that day, the regime of Hosni Mubarak, entrenched for 30 years and seemingly eternal, the only regime that the vast majority of the protesters had ever known, evaporated in one day.Though the regime struggled for two more weeks, practically little government existed during that period. All ministries and government offices have been closed, and almost all police headquarters were burned down on January 28. Except for the army, all security personnel disappeared, and a week after the uprising, only a few police officers ventured out again. Popular committees have since taken over security in the neighborhoods. I saw patriotism expressed everywhere as collective pride in the realization that people who did not know each other could act together, intentionally and with a purpose. During the ensuing week and a half, millions converged on the streets almost everywhere in Egypt, and one could empirically see how noble ethics—community and solidarity, care for others, respect for the dignity of all, feeling of personal responsibility for everyone—emerge precisely out of the disappearance of government.Undoubtedly this revolution, which is continuing to unfold, will be the formative event in the lives of the millions of youth who spearheaded it in Egypt, and perhaps also the many more millions of youth who followed it throughout the Arab world. It is clear that it is providing a new generation with a

  5. Chemical analysis of Yemeni archaeological cheramics and the Egyptian enigma

    Archaeological reconnaissance in Yemen produced samples of mediaeval Islamic ceramics in a 100 km2 region. The ceramics dated from 700 A.d. to 1750 A.D. and initial research indicated that they were all locally made products. 12 types of ceramics were selected for sampling on the basis of stylistic decoration. Six laboratory samples of each type were subjected to neutron activation analysis for the short-lived isotope producing elements using the SLOWPOKE reactor at the University of Toronto. A comparison with Egyptian pottery was carried out. The statistical analysis conducted on the Yemeni and Egyptian pottery produced discrete differences in their elemental composition which the archaeologist and the chemical scientist might not otherwise recognise. It is concluded that artifacts must be analyzed with due respect given to the archeological context, the elemental chemistry, and sound statistical procedures. (author)

  6. Egyptian Activism against Female Genital Cutting as Catachrestic Claiming

    An Van Raemdonck

    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.

    Author Summary Marburg virus, similar to its close cousin Ebola virus, can cause large outbreaks of hemorrhagic fever (HF) in rural Africa with case fatalities approaching 90%. For decades, a long-standing enigma has been the identity of the natural reservoir of this deadly virus. In this report, we identify the cave-dwelling Egyptian fruit bat (Rousettus aegyptiacus) as a natural host of Marburg virus based on multiple lines of evidence which include, for the first time ever, the isolation o...

  13. Nile Crossings: Hospitality and Revenge in Egyptian Rural Narratives

    Granara, William E.

    2010-01-01

    This essay looks at acts of hospitality and revenge as constituent elements of a broad social code in rural Egyptian narratives. By looking at five stories in particular, I argue that hospitality and revenge work in complementarity, and that they often trespass and blur each other’s social and literary borders, creating ambiguity and complexity in the stories. The traditional rules that govern hospitality are at times challenged or inverted by hostile intentions, and revenge may be exacted fo...

  2. Back to the roots - dermatology in ancient Egyptian medicine.

    Hartmann, Anke

    2016-04-01

    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

  3. The Media and the Making of the 2011 Egyptian Revolution

    Amr Osman

    2012-05-01

    Full Text Available While views may differ on the factors that made the 2011 Egyptian revolution possible, the role of mass media will remain undisputable. The Internet-based social networks caught the Mubarak regime by surprise, and the popular disillusionment with the ‘national’ media led the public to turn to private newspapers and satellite channels for keeping pace with the events. This paper examines the role of specific media during the 18 days of the 2011 Egyptian revolution – from 25 January to 11 February, 2011 – which we have divided into four parts. It discusses how these media contributed to the unfolding of events, conceptualized the protests and the demands of the public, and presented the actors that participated in or opposed the revolution. These points are addressed by discussing the content of the Facebook pages of the Sixth of April Movement and We Are All Khalid Said, as well as that of a private Egyptian newspaper, al-Shuruq, and the state-run newspaper al-Ahram.

  4. Did the ancient Egyptians migrate to ancient Nigeria?

    Jock M. Agai

    2014-01-01

    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. The subject is open for further research.

  5. Finding out egyptian gods' secret using analytical chemistry: biomedical properties of egyptian black makeup revealed by amperometry at single cells.

    Tapsoba, Issa; Arbault, Stéphane; Walter, Philippe; Amatore, Christian

    2010-01-15

    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.

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

    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)

    2014-01-01

    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

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

    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

  3. An investigation into the ancient Egyptian cultural influences on the Yorubas of Nigeria

    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.

    Samuel

    1996-07-26

    Ancient Egyptian methods of baking and brewing are investigated by optical and scanning electron microscopy of desiccated bread loaves and beer remains. The results suggest that current conceptions about ancient Egyptian bread and beer making should be modified. Bread was made not only with flour from raw grain, but sometimes also with malt and with yeast. Brewing blended cooked and uncooked malt with water; the mixture was strained free of husk before inoculation with yeast. PMID:8662535

    El Kinawy, Omayma S.

    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.

  15. The Reasons social media contributed to 2011 Egyptian Revolution

    Rabia Minatullah Sohail, Nadine Chebib

    2011-10-01

    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.

  16. Fallout Radioactivity in Some Egyptian Lakes Bottom Sediments

    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

  17. Characterization of Gamma-Irradiated Egyptian Wheat Flour

    Physical, rheological and baking properties of bread Shamy, prepared from gamma-irradiated Egyptian wheat flour up to 25 KGy as one of common types of bread in Egypt, were studied and the acceptability of bread was evaluated by sensory tests. All amylo-, farino-, and extensograph characteristics and also sample ph showed significant decrease as irradiation dose increased. Such results could be explained in terms of loss of unique elastic and cohesive properties of wheat gluten and starch damage upon increment of radiation dose. The improvement in properties of bread, baked from flour irradiated up to 7.5 KGy, could be explained on the basis of a simulation in gas production during dough fermentation due to increase in starch degradation products. However, bread, prepared from wheat samples irradiated above 7.5 KGy, exhibited significantly lower values of acceptance because of physico-chemical changes in both starch and gluten

  18. Synchrotron radiation analysis on ancient Egyptian vitreous materials

    Yamahana, Kyoko [Tokai Univ., Hiratsuka, Kanagawa (Japan). Lecture of Egyptian Archaeology

    2000-07-01

    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)

    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.

  1. Transmission Electron Microscopy (TEM) investigations of ancient Egyptian cosmetic powders

    Deeb, C.; Walter, P.; Castaing, J.; Penhoud, P.; Veyssière, P.

    The processing technologies available during the time of ancient Egypt are of present concern to the field of Archaeology and Egyptology. Materials characterization is the best tool for establishing the processing history of archaeological objects. In this study, transmission electron microscopy (TEM) is used, in addition to other techniques, for phase identification and study of the microstructure and characteristic defect structures in ancient Egyptian cosmetic powders. These powders generally consist of a mix of Pb-containing mineral phases: galena (PbS), cerussite (PbCO3), and phosgenite (Pb2Cl2CO3), among others. Modern materials are fabricated according to recipes found in ancient texts to mimic the processing of ancient times and to compare with the archaeological specimens. In particular, a comparison between the dislocation structures of PbS crystals deformed in the laboratory and PbS from archaeological specimens from the collections of the Louvre Museum is presented .

  2. Environmental Monitoring of Toshki Region As a New Egyptian Community

    Some heavy metal pollutants namely Cd, Co, Cu, Fe, Mn, Ni, PI and Zn were measured in water, soil and some fruit plants; Citrus finensis, Orantte folia, Citrus aurantium and Vitis vinifera in Toshki region. These samples were collected in March 2005. The samples were treated according to the Standard Operation Procedures, digested and analyzed using an atomic absorption spectrophotometer. It was found that the mean concentrations of the mentioned elements in water samples are higher than those corresponding by environmental Law. While, the concentrations of those elements in soil samples are two folds higher than those found in plant samples. The results are related to those give by the Egyptian environmental Law No. 4/1994. In addition, natural radioactivity levels for 226Ra, 232Th, 40K and137Cs in soil were found to be lower than those corresponding for United Nations Scientific committee on the Effect of Atomic Radiation (UNSCEAR) values. The results are discussed and recommendations are suggested

  3. Dose Assessment of Natural Radioactivity in Ancient Egyptian Monuments

    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)

  7. Studies on natural radioactivity of some egyptian building materials

    Using high-resolution y-rays spectrometry, the natural radioactivity of 14 samples of natural and o manufactured Egyptian building materials have been investigated. The samples were collected from local market and construction sites. From the measured gamma-ray spectra, specific activities were determined. The radium equivalent activity in each sample was estimated. Radiological evaluations of these materials indicate that all materials meet the external gamma-ray dose limitation. Calculation of concentration indices by assuming a Markkanen room model is constructed from these materials, to find the excess gamma-ray dose taken over that received from the outdoors. The Austrian Standard ONORM S 5200 is used in testing the building materials

    Genetic polymorphisms of encoding antigen B2 gene (AgB2) in Echinococcus granulosus were studied using PCR-RFLP and DNA sequencing among 20 Egyptian isolates. Five isolates from different host origins (humans, camels, pigs, and sheep) were collected and used. All examined isolates of each host group gave very similar patterns of PCR-RFLP after restriction enzyme digestion with AluI, with the gene size of approximately 140 bp and 240 bp for sheep and human isolates, and approximately 150 bp and 250 bp for pig and camel isolates. No digestion pattern was obtained after incubation of all studied isolates with EcoRI. These results reveal high intra-group homogeneity. DNA sequence analysis highlighted that human infecting strain showed 100% identity with respect to sheep infecting isolate, 96% and 99% with pig and camel infecting isolates, respectively.

  10. A descriptive study of plasma cell dyscrasias in Egyptian population

    Background: Plasma cell dyscrasias (PCDs) refer to a spectrum of disorders characterized by the monoclonal proliferation of lymphoplasmacytic cells in the bone marrow and, sometimes, tissue deposition of monoclonal immunoglobulins or their components. These disorders include multiple myeloma (MM) and Waldenstrom’s macroglobulinemia, as well as rare conditions such as light-chain deposition disease (LCDD) and heavy-chain diseases (HCDs). The worldwide annual incidence of MM is estimated at 86,000, which is approximately 0.8% of all new cancer cases. Purpose: Our retrospective study aims to highlight the immunologic and epidemiological features of PCDs mainly MM in Egyptian patients and compare our results with those of other populations. Methods: Two hundred seventeen Egyptian patients with PCD were enrolled in the study. Serum, urine protein electrophoresis and immunofixation were used to demonstrate M protein. Results: One hundred thirty-eight patients (63.6%) had IgG monoclonal band, 38 patients (17.5%) had IgA, 12 patients (5.5%) had Waldenstrom’s macroglobulinemia (IgM monoclonal band) and 29 patients (13.4%) were light chain myeloma. One hundred fifty-one (70%) were Kappa chain positive and 66 patients (30%) were lumbda positive. Conventional cytogenetics was available for 40 patients; of them12 patients (30%) showed 13q-. Mean OS was 37.5 months (1-84 months). Survival analysis was statistically insignificant according to age, sex and ISS or type of treatment (P value >0.05). Conclusion: Long term follow up is required to further define the role of different therapeutic lines of treatment including ASCT in the various stages of PCD based on OS data.

    2014-07-01

    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

    2011-12-01

    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

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

    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)

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

    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)

  15. The Identity Process in Times of Rupture: Narratives From the Egyptian Revolution

    Sarah Hassan Awad

    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.

  16. CARDIAC FUNCTION AND IRON CHELATION IN THALASSEMIA MAJOR AND INTERMEDIA: A REVIEW OF THE UNDERLYING PATHOPHYSIOLOGY AND APPROACH TO CHELATION MANAGEMENT

    Athanasios Aessopos

    2009-07-01

    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

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

    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.

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.

  20. Gonadotropins studies in female egyptian subjects under different physiological conditions

    This study is concerned with the role of the hypothalamic hypophyseal regulatory hormonal mechanisms in the control of gonadal secretions in a selected normal egyptian female subjects with varying ages under different physiological conditions. The study allowed precise definition of the modulator influence of a number of key factors triggering appropriate alteration in circulating serum levels of FSH and LH determined by IRMA technique in pre-pubertal female children (9-11), post-pubertal adolescents females (13-16). Adult married females (27-33) and post-menopausal (58-63). The levels of FSH and LH were increased markedly with age but children less than 11 years old had only nocturnal increase in levels of FSH (p.O.I) and LH(P< 0.001). post-pubertal aged girls had significant nocturnal elevation only of LH levels (P< 0.001), adult married females did not exhibit significant difference in gonadotropin concentrations. whereas significant elevation in FSH and LH levels (P<0.001) in post-menopausal females were observed

    The aim of this study was to identify gamma self-absorption correction factors for different types of Egyptian Mediterranean coastal sediments. Self-absorption corrections based on direct transmission through different thicknesses of the most dominant sediment species have been tested against point sources with gamma-ray energies of {sup 241}Am, {sup 137}Cs and {sup 60}Co with 2% uncertainties. Black sand samples from the Rashid branch of the Nile River quantitatively absorbed the low energy of {sup 241}Am through a thickness of 5 cm. In decreasing order of gamma energy self-absorption of {sup 241}Am, the samples under investigation ranked black sand, Matrouh sand, Sidi Gaber sand, shells, Salloum sand, and clay. Empirical self-absorption correction formulas were also deduced. Chemical analyses such as pH, CaCO{sub 3}, total dissolved solids, Ca{sup 2+}, Mg{sup 2+}, CO{sub 3}{sup 2-}, HCO{sub 3}{sup -} and total Fe{sup 2+} have been carried out for the sediments. The relationships between self absorption corrections and the other chemical parameters of the sediments were also examined.

    2013-12-01

    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.

    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.

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

    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

    Trzcielińska-Lorych, J; Jackowiak, H; Skieresz-Szewczyk, K; Godynicki, S

    2009-10-01

    The paper presents a comparison of the microscopic structure and morphometric traits of gustatory and mechanical lingual papillae in newborn and adult frugivorous Egyptian fruit bats (Rousettus aegyptiacus). All of the four types of lingual papillae found in adult animals were observed on the tongue surface in the newborn Egyptian fruit bats. After the birth, the gustatory papillae (fungiform and vallate papillae) were especially well-developed, as their structural characteristics, such as morphology of the epithelium and presence of the taste buds, indicate that they have reached almost complete functional traits. Mechanical papillae, particularly filiform papillae, in newborns are still fetal in character. Keratinization processes in the epithelium of these papillae are not advanced and specific structures, such as elongated processes, are missing. The morphometric analysis of the size of papillae and thickness of the mucosal epithelium showed that a complete development of keratinized structures in Egyptian fruit bats occurs at later stages of postnatal development.

    The dorsal lingual surface of the Egyptian rousette bat was examined by scanning electron microscopy. Filiform, fungiform and vallate papillae were observed. The filiform papillae were distributed over the entire dorsal surface of the tongue. The filiform papillae notably differed in morphology by their location on the tongue and could be classified into 5 types: 1) scalelike, 2) small crown-like, 3) giant trifid, 4) large crown-like, 5) conical papillae. The fungiform papillae were present rounded bodies on the anterior 2/3 of the tongue. The Egyptian rousette bat showed the a triangular arrangement of the three vallate papillae, with the apex of the triangle directed posteriorly. These findings indicate that the tongue of the Egyptian rousette bat is similar to that of the large flying fox. PMID:23429050

  10. Triple test screening for Down syndrome: an Egyptian-tailored study.

    Hazem S Abou-Youssef

    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.

    2014-01-01

    This article is the first academic study of Egyptian foreign policy towards Israel under Hosni Mubarak (1981–2011). It challenges a deeply entrenched conventional wisdom that Egypt pursued a cold-peace foreign policy towards Israel throughout this period. We demonstrate that Egyptian foreign policy towards Israel was dynamic – comprising cold peace (1981–91), a hybrid foreign policy of cold peace and strategic peace (1991–2003), and a pure strategic peace posture (2003–11). We also use the ca...

  14. [The Zagreb Etruscan ceremonial fragment and an ancient Egyptian medical papyrus].

    Grmek, M D

    1995-01-01

    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

  15. Count like an egyptian a hands-on introduction to ancient mathematics

    Reimer, David

    2014-01-01

    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.

  16. Egyptian And International Automotive Diesel. Fuels: Specifications Meeting Challenges To Refining Industry

    This paper presents a brief summary and comparison of Egyptian automotive diesel fuel to the international one. Recent legislation all over the world, requiring further reduction in sulfur, aromatics, T90 and T95 and increasing cetane value of the transportation diesel fuels, presents numerous technical and economic challenges to the refiners. While refiners grapple with these challenges, they will also face pressure from the increased demand of transportation diesel fuel and tighter capital restrictions. Overcome of these challenges makes a fair competition. A comparison of the Egyptian automotive diesel fuel and the international one will be a guide to locally and globally facing these challenges

  17. Biochemical and physiological changes in Egyptian Nile fish subjected to varying levels of gamma irradiation

    Radiation is nowadays to be considered as a new parameter in the ecology of water masses. Aquatic organisms, perhaps more than any other group of organisms, are directly exposed to radiation hazard and may be subjected to continuous low-level exposure from bottom material and from internal sources accumulated within their own bodies, originating partly from radionuclides released from nuclear facilities into the aquatic environment. In recent years, a large number of papers have been published on the uptake, concentration and release of radioactive material by aquatic organisms. However, radiation experiments on fish, a major source of food for human consumption, are still very rare and mostly restricted to studies on the effect of irradiation on eggs and larvae. Since the study of the radiation effect on living aquatic organisms, particularly fish, is important in connection with the problems of preserving water resources for the benefit of mankind, the work presented here has been done to ascertain the effect of varying dose-levels of gamma irradiation on two common Egyptian Nile fish species, the catfish Clarias lazera and the Tilapia nilotica. Investigations carried out on Clarias lazera involved blood and muscle analyses as well as growth rate measurements. The results obtained showed impaired haematological levels, changes in weight of muscle proteins and, chiefly, retardation in growth rate. Investigations carried out on Tilapia nilotica revealed changes in the activity of certain digestive enzyme systems, glucose level in blood and concentration of the glycogen store in liver and muscles. In discussing the results obtained the authors have taken the relevant literature into consideration. (author)

  18. New Codanin-1 Gene Mutations in a Italian Patient with Congenital Dyserythropoietic Anemia Type I and Heterozygous Beta-Thalassemia.

    D'Alcamo, Elena; Agrigento, V; Pitrolo, L; Sclafani, S; Barone, R; Calvaruso, G; Buffa, V; Maggio, A

    2016-06-01

    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

    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.

  1. Masked deficit of vitamin B12 in the patient with heterozygous beta-thalassemia and spastic paraparesis.

    Bilic, Ernest; Bilic, Ervina; Zagar, Marija; Juric, Stjepan

    2004-12-01

    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. PMID:15742609

    Scutellari, P N; Orzincolo, C; Andraghetti, D; Gamberini, M R

    1994-04-01

    Fifty-four homozygous beta-thalassemic patients (26 men and 28 women) aged 7 to 24 years, who had been treated with high transfusion regimen (Hb levels = 9-10 g/dl) and chelation therapy (desferrioxamine, 35-50 mg/kg), underwent clinical and radiographic investigations. This study was aimed at assessing the clinical and radiographic changes in the stomatognathic system (teeth, mandible and maxilla, occlusion relationship and dental bases). All patients underwent orthopantomography and teleradiography of the skull, in the lateral view. Twenty thalassemic patients (13 men and 7 women) of the same age but treated with low transfusion regimes (Hb levels = 5-6 g/dl) were examined as a control group. Our results indicate that: 1) in the control group, osteopenia is the specific lesion of anemia, in both the alveolar process and the mandible, following marrow expansion. Consequently, diastema of incisors and several types of malocclusion follow--i.e., overjet, anterior open-bite and crossbite, nearly all of them associated with II dental and skeletal patterns of Angle's classification. 2) In adequately transfused patients, no lesions are observed in 55% of cases, in both the teeth and the facial skeleton. This means that current treatment methods can prevent bone abnormalities, especially if transfusions begin at birth. Nevertheless, osteopenia of the mandible (31.4%) and dental and/or skeletal malocclusions (40.7%) remain in many cases, because of persistent marrow expansion, which usually follows incorrect treatment. 3) General dental diseases--e.g., caries, paradentosis, gingivitis, etc.--affect both populations with the same incidence.

    2013-07-01

    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.

  5. Cytokine Gene Polymorphisms in Egyptian Cases with Brain Tumors

    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.

    2014-01-01

    Full Text Available Context: Alopecia areata (AA is a common form of localized, non-scarring hair loss. The etiopathogenesis of the disease is still unclear, but the role of autoimmunity is strongly suggested. AA is commonly associated with various autoimmune disorders; the most frequent among them is autoimmune thyroid disorders. Aim: To determine whether AA is associated with thyroid autoimmunity or thyroid function abnormalities in Egyptian patients. Materials and Methods: Fifty subjects with AA (37 males and 13 females without clinical evidence of thyroid disorders were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital, Menoufiya Governorate, Egypt, during the period from June 2009 to February 2010. They were divided into 3 groups according to severity of AA. Fifty age and sex-matched healthy volunteers (35 males and 15 females were selected as a control group. Every case and control were subjected to history taking, complete general and dermatological examination. Venous blood samples were taken from cases and controls after taking their consents for measurement of thyroid stimulating hormone (TSH, free T3, freeT4 and detection of Anti-thyroglobulin Antibody (Tg-Ab and Anti-thyroid Peroxidase Antibody (TPO-Ab. Results: Subclinical hypothyroidism was detected in 16% of cases. There were statistically significant differences between cases and controls regarding levels of TSH, free T3 and free T4. There were significant differences between cases and controls regarding the presence of Tg-Ab and TPO-Ab. Conclusions: Every patient with AA should be screened for thyroid functions and presence of thyroid autoantibodies even in absence of clinical manifestations suggestive of thyroid affection.

  8. More than a Facebook revolution: Social movements and social media in the Egyptian Arab Spring

    Luis Fernando Barón

    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.

  11. Cats of the Pharaohs: Genetic Comparison of Egyptian Cat Mummies to their Feline Contemporaries.

    Kurushima, Jennifer D; Ikram, Salima; Knudsen, Joan; Bleiberg, Edward; Grahn, Robert A; Lyons, Leslie A

    2012-10-01

    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.

  13. US "Partnership" with the Egyptian Muslim Brotherhood and its Effect on Civil Society and Human Rights.

    Pierce, Anne R

    2014-01-01

    Looking at Egypt before, during and after the Arab Spring, this paper examines the intersection of Christian Copts, the Muslim Brotherhood, the Egyptian army, moderate Muslims and secular groups. In turn, it examines the Obama administration's policies toward Egypt. It discloses the surprising finding that the only consistent aspect of the administration's policy toward Egypt has been outreach to and engagement with the Muslim Brotherhood. At no time before or after the Brotherhood's ascent to prominence in Egyptian politics and society did the administration make support of the Brotherhood conditional. At no time did it use US leverage - given the massive amount of financial and military aid Egypt was depending on, and given the new Egyptian government's desire for prestige in the world community-to pressure the Morsi government to respect human rights, religious liberty and the impartial rule of law. Arguing that American foreign policy at its best is rooted in democratic ideals, this paper asks whether the United States, while respecting that Egyptians must choose their leaders and their political system, could have done more to encourage a positive strategic, moral and political outcome.

  17. Experimental Inoculation of Egyptian Rousette Bats (Rousettus aegyptiacus with Viruses of the Ebolavirus and Marburgvirus Genera

    Megan E.B. Jones

    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.

  5. Genetic Drift. The ancient Egyptian dwarfs of the Walters Art Museum.

    Kozma, Chahira

    2010-10-01

    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.

    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.

  9. Socioeconomic dynamics of water quality in the Egyptian Nile

    Malik, Maheen; Nisar, Zainab; Karakatsanis, Georgios

    2016-04-01

    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

  10. Increasing the Working Capabilities of the Egyptian Scanning Landmine Detectors

    This work describes and discusses the developments which were performed to increase the potential uses of Egyptian Scanning Landmine Detectors, ESCALAD. The ESCALAD apply two nuclear techniques for allocation and identification of landmines buried in arid soil like landmine fields in Egypt. The first technique is based on measuring thermal neutrons backscattered from the soil and the second one is based on measuring gamma-rays emitted from elements of landmine interrogated by fast and thermal neutrons when the soil is irradiated by fast neutrons from Pu-α-Be sources. The developed systems with their associated detectors, neutron sources, measuring electronics and data analysis modules are mounted on an electrically driven trolley. The neutron backscattering NBS device detects landmines by the recognition of hydrogen density variation between explosive material, of a landmine and its surroundings, soil and other scattered objects. When a high energy neutron flux from Pu-α-Be sources penetrates the soil in which the landmine is buried, the neutrons undergo successive moderation processes until they come back with thermal energy. An array of two dimensional position sensitive thermal neutron detectors of 3He was used to monitor the backscattered thermal neutrons and for each neutron the position of hit along the tube with respect to the position on the ground is recorded. The elemental analysis technique is regarded as a complementary sensor of ESCALAD in which the gamma rays produced from fast/thermal neutrons interactions with the buried objects (i.e., a landmine) are measured. The measured response for gamma-rays is given as gamma ray spectrum. A mine is recognized through measuring the difference in the elemental composition, especially H, C, N and O. To increase the working capabilities of ESCALAD, different design mechanisms were developed for mount the detectors tray to overcome the effect of soil surface roughness and standoff distance on scanning capability

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

    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

    Nelly Ramzy

    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. Biodegradation Ability and Catabolic Genes of Petroleum-Degrading Sphingomonas koreensis Strain ASU-06 Isolated from Egyptian Oily Soil

    2014-01-01

    Full Text Available Polycyclic aromatic hydrocarbons (PAHs are serious pollutants and health hazards. In this study, 15 PAHs-degrading bacteria were isolated from Egyptian oily soil. Among them, one Gram-negative strain (ASU-06 was selected and biodegradation ability and initial catabolic genes of petroleum compounds were investigated. Comparison of 16S rRNA gene sequence of strain ASU-06 to published sequences in GenBank database as well as phylogenetic analysis identified ASU-06 as Sphingomonas koreensis. Strain ASU-06 degraded 100, 99, 98, and 92.7% of 100 mg/L naphthalene, phenanthrene, anthracene, and pyrene within 15 days, respectively. When these PAHs present in a mixed form, the enhancement phenomenon appeared, particularly in the degradation of pyrene, whereas the degradation rate was 98.6% within the period. This is the first report showing the degradation of different PAHs by this species. PCR experiments with specific primers for catabolic genes alkB, alkB1, nahAc, C12O, and C23O suggested that ASU-06 might possess genes for aliphatic and PAHs degradation, while PAH-RHDαGP gene was not detected. Production of biosurfactants and increasing cell-surface hydrophobicity were investigated. GC/MS analysis of intermediate metabolites of studied PAHs concluded that this strain utilized these compounds via two main pathways, and phthalate was the major constant product that appeared in each day of the degradation period.

    Polycyclic aromatic hydrocarbons (PAHs) are serious pollutants and health hazards. In this study, 15 PAHs-degrading bacteria were isolated from Egyptian oily soil. Among them, one Gram-negative strain (ASU-06) was selected and biodegradation ability and initial catabolic genes of petroleum compounds were investigated. Comparison of 16S rRNA gene sequence of strain ASU-06 to published sequences in GenBank database as well as phylogenetic analysis identified ASU-06 as Sphingomonas koreensis. Strain ASU-06 degraded 100, 99, 98, and 92.7% of 100 mg/L naphthalene, phenanthrene, anthracene, and pyrene within 15 days, respectively. When these PAHs present in a mixed form, the enhancement phenomenon appeared, particularly in the degradation of pyrene, whereas the degradation rate was 98.6% within the period. This is the first report showing the degradation of different PAHs by this species. PCR experiments with specific primers for catabolic genes alkB, alkB1, nahAc, C12O, and C23O suggested that ASU-06 might possess genes for aliphatic and PAHs degradation, while PAH-RHDαGP gene was not detected. Production of biosurfactants and increasing cell-surface hydrophobicity were investigated. GC/MS analysis of intermediate metabolites of studied PAHs concluded that this strain utilized these compounds via two main pathways, and phthalate was the major constant product that appeared in each day of the degradation period.

    2016-01-01

    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.

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

    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).

    AIM:To describe the clinical and epidemiologic profiles of the disease and to compare the findings with those generated from the previous hospital-based studies.METHODS:The Gharbiah cancer registry is the only population-based cancer registry in Egypt since 1998.We analyzed the data of all colorectal cancer patients included in the registry for the period of 1999-2007.All medical records of the 1364 patients diagnosed in Gharbiah during the study period were retrieved and the following information abstracted:age,residence,diagnosis date,grade,stage,topology,clinical characteristics,and histology variables.Egyptian census data for 1996 and 2006 were used to provide the general population's statistics on age,sex,residence and other related demographic factors.In addition to age-and sex-specific incidence rate analyses,we analyze the data to explore the incidence distribution by rural-urban differences among the 8 districts of the province.We also compared the incidence rates of Gharbiah to the rates of the Surveillance Epidemiology and End Results (SEER) data of the United States.RESULTS:Over the 9 year-period,1364 colorectal cancer cases were included.The disease incidence under age 40 years was relatively high (1.3/105) while the incidence in the age groups 40 and over was very low (12.0/105,19.4/105 and 21.2/105 in the age groups 40-59 years,60-69 years and > 70 years,respectively).The vast majority of tumors (97.2%) had no polyps and 37.2% of the patients presented with primary lesions in the rectum.Colorectal cancer was more common in patients from urban (55%) than rural (45%) areas.Regional differences in colon and rectal cancer incidence in the 8 districts of the study province may refleet different etiologic patterns in this population.The registry data of Egypt shows a slightly higher incidence of colorectal cancer than the United States in subjects under age 40 years.The results also shows significantly lower incidence of colorectal cancer in

  3. Prevalence of bone marrow necrosis in Egyptian cancer patients referring to the National Cancer Institute

    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

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

    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.

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

    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

  6. [Medicine and philosophy, and undissolvable link. Literary focus on contributions of Egyptian culture to medicine].

    González-Arrieta, María Leonor

    2004-01-01

    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.

    2013-08-01

    We applied, for the first time, next-generation sequencing (NGS) technology on Egyptian mummies. Seven NGS datasets obtained from five randomly selected Third Intermediate to Graeco-Roman Egyptian mummies (806 BC-124AD) and two unearthed pre-contact Bolivian lowland skeletons were generated and characterised. The datasets were contrasted to three recently published NGS datasets obtained from cold-climate regions, i.e. the Saqqaq, the Denisova hominid and the Alpine Iceman. Analysis was done using one million reads of each newly generated or published dataset. Blastn and megablast results were analysed using MEGAN software. Distinct NGS results were replicated by specific and sensitive polymerase chain reaction (PCR) protocols in ancient DNA dedicated laboratories. Here, we provide unambiguous identification of authentic DNA in Egyptian mummies. The NGS datasets showed variable contents of endogenous DNA harboured in tissues. Three of five mummies displayed a human DNA proportion comparable to the human read count of the Saqqaq permafrost-preserved specimen. Furthermore, a metagenomic signature unique to mummies was displayed. By applying a "bacterial fingerprint", discrimination among mummies and other remains from warm areas outside Egypt was possible. Due to the absence of an adequate environment monitoring, a bacterial bloom was identified when analysing different biopsies from the same mummies taken after a lapse of time of 1.5 years. Plant kingdom representation in all mummy datasets was unique and could be partially associated with their use in embalming materials. Finally, NGS data showed the presence of Plasmodium falciparum and Toxoplasma gondii DNA sequences, indicating malaria and toxoplasmosis in these mummies. We demonstrate that endogenous ancient DNA can be extracted from mummies and serve as a proper template for the NGS technique, thus, opening new pathways of investigation for future genome sequencing of ancient Egyptian individuals.

    Van Eynde, Koen

    2015-01-01

    Research of men and masculinities in the Middle East and North Africa remains scarce, to say the least. Only occasionally and irregularly researchers pay attention to the topic, while gender studies in the region continues to focus on women. Nevertheless, the term gender incorporates more than just women. In practice, however, we find little information on Egyptian and Arab men and masculinities.This lack is partly explained by the interests of gender studies in this specific geographic regio...

    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.

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

    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

  4. Comparative Study Between The IAEA Model Regulations and The Egyptian Nuclear Law

    This study deals with the security of radioactive sources due to its great importance, in order to provide the adequate security of these sources from the threat of theft, sabotage, illegal seizure through doing a comparison between the model regulations of the International Atomic Energy Agency (IAEA) (11) and the Egyptian law (No. 7/2010) that regulates nuclear and radiation activities and its executive regulations. The Egyptian legislator has put a chapter entitled nuclear securitywith the aim of organizing the security of nuclear materials. However, there was a review to some regulatory rules issued by the IAEA on the security of these sources which include the responsibilities of the licensee towards it. This chapter also, addressed the security culture through rehabilitation and training, in addition to the obligations of the competent authorities who is responsible for the process of issuing the license when full requirements are met. It has been shown that the Egyptian law and its executive regulations contained the rule that provides the necessary protection for these radioactive sources. Furthermore, more regulations are still needed to provide adequate security and more protection for the radioactive sources and its facilities

  5. Preparation of precipitated barium sulphate from Egyptian barytes ore and its application in paints

    Precipitated barium sulphate (Blank fixe) was prepared and evaluated as an extender pigment, making use of the naturally occurring Egyptian barytes ore. X-ray diffraction patterns, transmission electron microscope, thermal gravimetric analysis, color measurements, specific gravity, oil absorption, bulking value, bleed resistance, hydrogen ion concentration, permanence for light and heat and chemical resistance were different methods used for characterization and evaluation of the prepared pigment. Medium oil alkyd resin, melamine-alkyd and epoxy resin were used as different binding media for the application and testing of the prepared pigments as an extender- in some paint formulations, this was done in comparison with a commercial imported blank fixe sample and the Egyptian barytes ore that it was prepared from. It was found that; a white bright fine powder of precipitated barium sulfate could be successfully prepared from the locally abundant Egyptian barytes ore. It has a suitable properties as an extender pigment. Paints pigmented with blank fixe offered favourable rheological and protective properties exceeding that of the imported commercial sample and the ore that was prepared from

    BACKGROUND: The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended. AIM: To figure out food habits and different lifestyle pattern among a sample of Egyptian females working at the National Research Centre. METHODS: A cross-sectional, descriptive study, including 138 overweight and obese Egyptian females (BMI ≥ 25 Kg/m2); working at the National Research Centre; was done. A specific questionnaire was used to gather information regarding lifestyle including dietary habits, physical activity and sedentary behaviour. RESULTS: The prevalence of overweight among the studied subjects was 27%, while that of obesity was 38%. Missing and or infrequent intake of breakfast at home, frequent consumption of snacks, low serving per day of fruits and vegetables with frequent consumption of sweets, fried food, eating while watching TV and sedentary behaviour were all predictors of obesity and overweight among the current sample. CONCLUSION: The present study identified several lifestyle factors and improper dietary habits associated with overweight and obesity among Egyptian females. There is a great need to change these habits to avoid the increasing risk of obesity. A national plan of action to overcome obesity is urgently needed to reduce its economic and health burden.

    Full Text Available This study aims to measure the gap between the administration and the beneficiaries of the quality of the service in the federation and sport regions of Karate. The sample of this study was chosen randomly between the members of the board of directors of the Federation and regions, the coaches , referees and players registered in theEgyptian Federation of Karate whose numbers are (149. The sample of the study was classified into two beneficiary classes. The first beneficiary class is coaches and referees whose number are (70 persons and their administration is the members of the board of directors of the Federation and its regions whose number are (14persons. The second class is the players whose number are (65 players and their administration is the members ofthe board of directors of the Federation and its regions the referees and coaches' number are (84 persons. This study used a questionnaire (SERVQUAL to measure the quality of the service. Results pointed to a negative gap between the expectations of the beneficiaries of the excellent service level and the perceptions of the administrations of these expectations.These results refer to the weakness of administration ability in the Egyptian Federation of Karate to know the needs and desires of beneficiaries from (coaches-referees- players of the quality level in the service provided to them. The existence of a relative gap between the perceptions of the beneficiaries of the service actually provided and the administration of the qualities of the service actually provided, therefore itrefers to the decline the motive level of the administration of Egyptian Federation of Karate to provide the service to the beneficiaries in a form that conforms with what the administration already decided for the specifications. The existence of a negative gap between the expectations of the beneficiaries of the level of theexcellent service and its perception of the actual performance of this service refers to

    Mousa, Somaia Mohammed; El-Ghamrawy, Mona Kamal; Gouda, Heba; Khorshied, Mervat; El-Salam Ahmed, Dina Abd; Shiba, Hala

    2016-01-01

    Background and Objectives Hepatitis C virus (HCV) is a major health problem in Egypt with its prevalence estimated to be 14.7% among the general population in 2008. Patients receiving frequent blood transfusions like those with sickle cell disease (SCD) are more exposed to the risk of acquiring HCV. IL28B gene polymorphisms have been associated with spontaneous HCV clearance. This study aims to determine the prevalence of HCV infection among children with SCD and to investigate the relation between IL28B gene polymorphisms and spontaneous HCV clearance. Methods Seventy SCD patients were screened for HCV antibody. HCV-positive patients were tested for the level of HCV RNA using quantitative real-time PCR. IL28B polymorphisms (rs 12979860 SNP and rs 12980275 SNP) were detected using TaqMan QRT-PCR and sequence-specific primers PCR respectively. Results Sixteen patients (23%) were HCV antibody positive, 9 of them (56.3%) had undetectable HCV RNA in serum, and 7 (43.7%) had persistent viremia. Genotypes CC/CT/TT of rs12979860 were found in 30 (42.9%), 29 (41.4%) and 11 (15.7%) patients and rs12980275 AA/AG/GG were found in 8 (11.4%), 59 (84.3%) and 3 (4.3%) patients. There was no significant difference in the frequency of IL28B (rs 12979860 and rs12980275) genotypes among HCV patients who cleared the virus and those with persistent viremia (p=0.308 and 0.724 respectively). Conclusion Egyptian SCD patients have a high prevalence of HCV. Multi-transfused patients still exposed to the risk of transmission of HCV. IL28B gene polymorphismsare not associated with spontaneous clearance of HCV in this cohort of Egyptian children with SCD. PMID:26740868

    2016-05-01

    The aims of this study are to present the results of Egyptian RA patients included in COMORA cohort and compare it to general COMORA cohort, concerning prevalence of comorbidities, and level of application of recommendations related to detection/prevention of comorbidities. Three-hundred eight Egyptian RA patients included in the cross-sectional, observational, multi-center, international study "COMORA", were compared to the total number of 3612 RA patients. The CRF of COMORA was used in all patients. CRF collects demographic and disease characteristics, comorbidities, risk factors, and compliance with recommendations regarding management of comorbidities. Data were analyzed according to COMORA protocol. Egyptian RA patients were significantly younger, had more active disease, and were more functionally disabled. They showed more frequent use of NSAIDs, methotrexate and steroids and significantly lower use of bDMARDs when compared to non-Egyptians. Egyptian patients had the highest ever HCV prevalence, while depression, hypertension, smoking and dyslipidemia were less prevalent in Egyptians. Prevalence of malignancy risk factors was highly deficient among Egyptians; primarily due to lack of screening. Further, following recommendations for monitoring comorbidities is significantly deficient among Egyptian patients. Egyptian patients had more active disease and more functional impairment than the rest of the COMORA cohort; with lower use of bDMARDs, that is possibly related to the economic situation. Also, there is a clear gap in screening and monitoring comorbidities. Awareness among Egyptian healthcare providers (and possibly similar third-world countries) to detect and manage RA-related comorbidities is required. PMID:26670453

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

    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.

  14. 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.

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

    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

  18. Lead isotope systematics of some igneous rocks from the Egyptian Shield

    Gillespie, J. G.; Dixon, T. H.

    1983-01-01

    Lead isotope data on whole-rock samples and two feldspar separates for a variety of Pan-African (late Precambrian) igneous rocks for the Egyptian Shield are presented. It is pointed out that the eastern desert of Egypt is a Late Precambrian shield characterized by the widespread occurrence of granitic plutons. The lead isotope ratios may be used to delineate boundaries between Late Precambrian oceanic and continental environments in northeastern Africa. The samples belong to three groups. These groups are related to a younger plutonic sequence of granites and adamellites, a plutonic group consisting of older tonalites to granodiorites, and the Dokhan volcanic suite.

  19. Yellow, red and blue pigments from ancient Egyptian palace painted walls

    Yellow, red and blue pigments from the painted walls of the Malqata palace, founded by Amenhotep III, 18th Dynasty, were analyzed using PIXE and X-ray diffraction (XRD). From most of the yellow, red and blue parts, goethite, hematite and Egyptian blue, respectively, were found on the basis of diffractometry results. From some yellow parts, As was detected together with Fe spectroscopically, suggesting the use of orpiment as a yellow pigment. The red pigment seems to be natural and not man-made. This assumption is deduced from the dehydration experiment of a synthesized goethite

    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.

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

    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

  5. Retention of uranium from liquid waste solution onto Egyptian Natural Clay

    The retention of uranium from its aqueous local waste solution was studied using Egyptian natural clay as adsorbent. The equilibrium batch technique was employed and the effects of contact time, pH, and effect of irons, temperature and initial uranium concentration on the adsorption process were studied. Equilibrium adsorption was reached within 60 min. The data obtained were fitted with the langmuir, Freundlich and Dubinin-Radushkevich isotherm models. The best fit was obtained Langmuir isotherm, which indicates that the maximum adsorption capacity is about 44 mg/g. (Author)

    2012-12-01

    Full Text Available The historical role of the Suez Canal as a pathway for migrations between the Red sea and the Mediterranean is recalled. A check-list of 42 immigrant Erythrean fish in Egyptian Mediterranean waters is given. The list comprises four new records. 17 of the immigrant species are commercially exploited, whereas 15 are known from single records. While the Erythrean fish as invasive species are beneficial to local fisheries, in our view, they do not have an important impact upon the ecosystem.

    2007-01-01

    This thesis examines state-society relations in Egypt, and the logic of durable authoritarianism since 1952. It does so through an examination of the Egyptian state’s neglectful rule, from the 1970s through the 1990s, of its capital Cairo. In particular, the thesis focuses on state inaction vis-à-vis Cairo’s informal housing sector: those neighbourhoods established on land not officially sanctioned for urbanization. The central research question of the thesis is to explain why the Egyptia...

  10. Adapting Pd Gains with Neural Network for Egyptian Second Research Reactor (ETRR-2)

    There is no doubt that selection of conventional Pd gains has a great influence over the system performance. So, this paper presents a developed adapted Pd (APD) control system to fit suitable control action. This system is based on ANN to select, on-line, the proper gains for Pd controller. Both Pd and developed APD control systems are simulated with Egyptian Second Research Reactor (ETRR-2) model subjected to different perturbations. Simulation results proved that, APD controller has faster response than Pd, besides its capability of absorbing more reactivity variations

  11. Effect of gamma irradiation on the morphological characteristics of some pigmented streptomycetes isolated from Egyptian soils

    Out of thirty actinomycetes isolated from Egyptian soils, fourteen isolates exhibited antimicrobial activity. Of these, only two had the highest antimicrobial activity against bacteria, moulds and yeasts. They were pigmented and identified as Streptomyces Albaduncus and S. erythrogresius. Both isolates were found to be relatively radioresistant with D10 values of 0.90 kGy for S. Albaduncus and 0.72 kGy for S.erythrogresius. Different radiation dose levels used (0.25-5.0 kGy) caused changes in the morphological properties of both isolates especially at relatively high doses (2.0-5.0 kGy)

    Aflatoxins production by Aspergillus Flavus isolate on several types of egyptian bread samples through a period of 45 days at different temperatures reveled that there was detectable fungal growth but no aflatoxins were produced at 5±1 degree or 37 degree. At 25 degree or 30 degree aflatoxin were produced after 5-6 days on the different bread types. Gamma irradiation of kaiser bread, previously inoculated with Aspergillus Flavus, reduced the amount of aflatoxins produced on subsequent storage for 8 weeks at 26±1 degree. The 5 KGy dose eliminated fungal growth and aflatoxin production. 4 tab

    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.

  1. Residual Nitrite in Some Egyptian Meat Products and the Reduction Effect of Electron Beam Irradiation

    Dalia A. Zahran

    2011-10-01

    Full Text Available Nitrite, a curing agent of meat products, is a precursor of carcinogenic N-nitrosamines during processing of meat products or under human stomach conditions, as well as having its own toxicity. To investigate the residual nitrite level in meat products marketed in Egyptian markets, 160 samples of cured cooked (luncheon and frankfurter and cured raw (oriental sausages and pastirma meat products (40 sample each were analyzed for residual nitrite by a spectrophotometric method. Samples were subjected to irradiation (3.0 and 5.0 kGy by electron beam accelerator to evaluate its effect on the residual nitrite level in the examined cured meat products. For statistical analysis, means and standard errors of residual nitrite level were determined and analyzed by one-way analysis of variance. The results revealed that the residual nitrite level was ranging between 10.45-251.6 ppm in the examined meat products and that pastirma had the highest residual level (p<0.05 while luncheon showed the least level. Residual nitrite level was significantly reduced (p<0.05 by electron beam irradiation (5.0 kGy and the reduction was dose dependent. This demonstrated that it would still be important to strengthen on control of residual nitrite level in Egyptian meat products and food safety education for public people.

    2012-01-01

    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.

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

    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

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

    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.

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

    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.

  6. Near eastern neolithic genetic input in a small oasis of the Egyptian Western Desert.

    Kujanová, Martina; Pereira, Luísa; Fernandes, Verónica; Pereira, Joana B; Cerný, Viktor

    2009-10-01

    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

  7. Renin-angiotensin system genes polymorphism in Egyptians with premature coronary artery disease.

    2012-05-01

    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

  8. Combined FT-Raman spectroscopic and mass spectrometric study of ancient Egyptian sarcophagal fragments.

    Edwards, Howell G M; Stern, Ben; Villar, Susana E Jorge; David, A Rosalie

    2007-02-01

    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.

  9. The Lexical Knowledge and Avoidance of Phrasal Verbs: The Case of Egyptian Learners of English

    Dina Abdel Salam El-Dakhs

    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

  10. Consultation for Small-Sized Penis in the Egyptian Males: A Case Control Study.

    Salama, Nader

    2016-05-01

    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. PMID:25563384

  12. Synthesis of high purity rutile nanoparticles from medium-grade Egyptian natural ilmenite

    Mohamed G. Shahien

    2015-09-01

    Full Text Available The Egyptian magmatic ilmenite is classified as a medium-grade ore. The present work is an attempt to produce a high-quality TiO2 that can be used in several industries from this medium-grade raw material using the mechanical activation, carbothermic reduction, hydrochloric acid leaching and calcination. A mixture from the ilmenite (FeTiO3 and activated carbon was milled for 30 h. This mixture was annealed at 1200 °C for one hour and the product was leached by hydrochloric acid and calcined at 600 °C for two hours. The role of the ball milling was to grind the raw ilmenite to obtain the nano size, and the carbothermic reduction was to reduce all the Fe-Ti phases to a mixture from Fe metal and TiO2. Leaching procedure was carried out to remove all the Fe metal and obtain a high-grade TiO2. After leaching and calcination of the milled and annealed mixture of FeTiO3/C under the optimal conditions, TiO2 nanoparticles with a size of 10–100 nm and purity more than 95% were obtained. The qualifications of the synthesized high purity rutile nanoparticles from the Egyptian natural ilmenite match the conditions of many industrial applications.

  13. Egyptian Revolution of 2011 and the Power of Its Slogans: A Critical Discourse Analysis Study

    Khaled Al Masaeed

    2013-12-01

    Full Text Available Egypt, the most populated country in the Arab world, erupted in mass protests in January 2011 against the oppressive rule of President Hosni Mubarak. Protesters all over Egypt in general and in Tahrir Square in Cairo wanted Mubarak to leave. Protesters used different dialects, languages, and modes to get their message across. After 18 days of angry protests and after losing the support of the military and the US, Mubarak finally understood the message and resigned on Feb. 11, ending almost 30 years of dictatorial rule. This article builds on studies in Critical Discourse Analysis (CDA and its implementation of interdisciplinarity to investigate the slogans―fixed expressions, usually chosen carefully by organizers and activists, which are often chanted by political groups and protestors at demonstrations that were used during the Egyptian revolution in late January and February 2011. Moreover, the article shows how CDA―through embracing text as a dialogue and site for interaction, social goods and social languages, interpersonal relations and discourse, multimodality, and intertextuality can help to produce theoretically sound interpretation that is appropriate for the analysis of how Egyptians used the power of language through these slogans to empower themselves, challenge their government, and overthrow the former president Hosni Mubarak.

  14. Establishment of an absolute chronology for the 18th Egyptian Dynasty

    The establishment of an absolute chronology for Ancient Egypt is an ambition which has concentrated efforts of many scholars since the beginning of Egyptology. Thanks to historical and archaeological documents, a relative chronology of the kings has been built. Only some astrophysical points and synchronisms listed in texts (Greek and Egyptian sources) have given some ankle points which have led to some propositions of absolute chronology. At first, we will see how we can re-calculate some ankle points by using Sothic dating and modelling lunar dates with a Bayesian approach. Then, radiocarbon measurements have been done at Laboratoire de Mesure du Carbone 14 (CEA Saclay) on Egyptian short life materials like plants or twigs. These objects come from the Louvre Museum and are attributed to a particular reign and a precise period. With a Bayesian approach, these analyses have been combined with the known succession and length of the reign. Besides, Sothic and lunar dates have been incorporated as a prior in the model. It has led to propose an absolute chronology for the 18th dynasty. Finally, we will discuss the agreement between our results and archaeological evidence and will see if this chronology can highlight points where Egyptologists disagree. (author)

    Alaa Mohamed Youssef

    2014-01-01

    Full Text Available License Plate Recognition (LPR is the most important type of Intelligent Transportation System (ITS. LPR is used in many different types of ITS like electronic payment systems, toll station, parking fees, freeway and arterial management systems for traffic surveillance. Few years ago, Egyptians government changed the car license plate to include letters and numbers. So the needs for efficient LPR System for the new license plate are increased in different ITS fields. This study presents an enhanced LPR detection algorithm for the new Egyptian licenses plate. The detection enhancement is done using Stroke Width Transform algorithm to extract letters from candidate areas combined with Fuzzy ARTMAP classifier. Stroke Width Transform (SWT is a state of art algorithm developed by Microsoft Research Lab for detecting text in natural scene, it seeks to find the value of stroke width for each image pixel and demonstrate its use on the task of text detection in natural images. This study is focusing on detecting Arabic letters in the candidate license plate area using SWT image map instead of binary image map where not all Arabic letters have uniformly stroke width and some letters have a dot above and below it. The proposed model shows 26% detection accuracy enhancement than conventional LPR systems (Sobel Edge detection with binary image map using template matching technique.

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

    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

  19. Treatment outcomes of female germ cell tumors: The Egyptian National Cancer Institute experience

    Introduction: Female germ cell tumors (GCTS) are rare tumors that carry a good prognosis. Aim: To report the experience of the Egyptian National Cancer Institute (ENCI) in managing female GCTs. Methods: This retrospective study included 19 females with ovarian GCTs presenting to the ENCI between 2006 and 2010. Results: The median age was 23 years. Ovaries were the primary site in all patients. Dysgerminoma and teratoma were the predominant pathologies followed by mixed GCT in females. Unilateral ovariectomy or ovarian tumorectomy were the classic surgical procedures with R0 resection being feasible in most cases. Surveillance was adopted in six patients with stage I disease. Chemotherapy was administered in 63% of ovarian GCTs with BEP being the commonest regimen with reasonable tolerability and good response rates. The median OS and EFS were not reached. The projected 5-year OS rate was 93.8%. Both OS and EFS were better in patients responding to chemotherapy than non-responders (p< 0.002). Stage of disease did not significantly affect OS or EFS. Conclusions: Female GCTs rarely affect Egyptian females. They have good prognosis.

  20. 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.

  1. Essential oils from Egyptian aromatic plants as antioxidant and novel anticancer agents in human cancer cell lines

    Ramadan, M. M.

    2015-06-01

    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. La citotoxicidad y la acción anticancerígena in vitro de aceites esenciales de tomillo, enebro y clavo han sido evaluadas en cinco líneas celulares de cáncer humano (hígado HepG2, mama MCF-7, próstata PC3, colon HCT116 y pulmón A549. Los análisis de GC/MS mostraron que α-pineno, timol y eugenol son los principales componentes de los aceites egipcios de enebro, tomillo y clavo, con concentraciones de 31,19%, 79,15% y 82,71%, respectivamente.

    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.

  5. A New Interpretation of the Transport and Erection of Large Obelisks by Ancient Egyptian Engineers or Englebach Revisited.

    Spry, William J.

    In the teaching of archaeology at the university level there is often conflict between the engineer and the humanist when looking at archaeological evidence. Nowhere is this more clear than in considering the very old puzzle of how ancient Egyptian engineers transported and erected huge stone obelisks using only human labor. The humanist, whose…

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

    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

  11. A RISK-AWARE BUSINESS PROCESS MANAGEMENT REFERENCE MODEL AND ITS APPLICATION IN AN EGYPTIAN UNIVERSITY

    Mohamed H. Haggag

    2015-05-01

    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.

    Mahmoud, Mohamed; Abdelrahman, Khaled; Soliman, Hatem

    2010-10-01

    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

  14. Short report: cysticercosis in an Egyptian mummy of the late Ptolemaic period.

    Bruschi, Fabrizio; Masetti, Massimo; Locci, Maria Teresa; Ciranni, Rosalba; Fornaciari, Gino

    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.

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

    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.

  16. US comments on Egyptian paper INFCE/DEP./WG-4/134

    This paper makes an estimate of the cost to Egypt of the programme of plutonium recycle described in INFCE/DEP./WG-4/133 and 134. This was done by estimating the spent fuel arisings that might be anticipated from the Egyptian programme and the costs related to spent fuel transport, reprocessing, waste transport and disposal, based on the unit fuel cycle costs summarised in INFCE/DEP./WG--4/85. The paper concludes that the cost to Egypt of plutonium recycle would appear to exceed the savings described in INFCE/DEP./WG-4/134. The paper goes on to perform a simple cost benefit analysis of storing the spent fuel arising from Egypt's nuclear programme and concludes that the once-through cycle could save a small nuclear programme like Egypt's several hundred million dollars by the turn of the century

    1995-12-31

    This paper describes the results of an investigation into the impact of the thyristor controlled reactor (TCR) installations (static VAR compensators) at Cairo in the Egyptian 500 kV power system. The study is performed for three distinct system configurations, which correspond to stages of system development up to year 2000. The simulation tool for this study is the McGraw-Edison V-HARM and the system solution is obtained at all frequencies of interest. Two types of simulations are performed and described in this paper: 1. Frequency scans are used to determine system response characteristics independent of the actual harmonic generation levels. A one Ampere current injection over a wide frequency range is used for these cases. 2. Actual harmonic level simulations are performed with the thyristor-controlled reactor harmonic generation characteristics modeled explicitly. In these cases, harmonic voltage levels resulting from the TCRs are calculated throughout the system. 5 refs, 10 figs, 2 tabs

  18. Application of multi-element clustering techniques of five Egyptian industrial sugar products

    The concentration of 18 elements in different cane sugar products, i.e., cane sugar plants, crude and syrup juices, molasses, and the end products of the consumer sugar, were analyzed and processed. The samples were collected from five cities, i.e., Kom Ombo, Edfu, Armant, Deshna and Naga Hammady in Upper Egypt where the main Egyptian sugar industry factories are located. INAA was applied for the determination of Al, Ca, Cl, Co, Cr, Fe, Mg, Mn, Na, and Sc, while Cu, Li, P, Sn, V and Zn were determined by ICP-AES and Pb and As were determined by AAS. These three analytical methods were applied to optimize the sensitivity and the accuracy of the measurements in order to provide a sound basis for the obtention of reliable clustering results.

  19. THE REVOLUTION AND THE MILITARY. AN ANALYSIS OF THE EGYPTIAN AND IRAQI REVOLUTIONS

    Radu-Alexandru CUCUT

    2010-06-01

    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.

    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.
