Imidacloprid (IMI) is very harmful to human health and cause problems. Recently, plants have been considered as potential agents for protection against these disorders. Urtica urens L. (UU) is very useful for relieving rheumatic pains and there is no scientific evidence justifying its use, which lets us think of its direct effect on the bone. This study aimed to investigate the protective effect of UU against toxicity effects of IMI in female rat. Rats were divided into control group, 3 groups treated with IMI at 50, 200 or 300mg/kg/day and 3 groups co-treated with IMI (50, 200 or 300mg/kg/day)+100mg/kg/day of UU...

BACKGROUND & AIMS: We tested if decreased total and high molecular weight (HMW)-adiponectin, and altered HMW/total adiponectin ratio (HMWR) constitute reliable markers of polycystic ovary syndrome (PCOS) among Bahraini Arab women. METHODS: Case-control study involving 122 Bahraini Arab women with PCOS and 89 ethnically-matched control women. PCOS was evaluated according to 2003 Rotterdam criteria. Total and HMW-adiponectin were measured by ELISA. RESULTS: Compared to controls, women with PCOS had significantly reduced plasma HMW-adiponectin, and HMWR, more so than total adiponectin...

BACKGROUND: Tongue resection is a surgical challenge because of its adverse effects on language articulation, swallowing, respiration, the eventual quality of life, and poor prognosis of advanced disease. To date, the currently accepted standard treatment has been based on excision of the primary lesion with a 1.5-2-cm circumferential macroscopic margin. Compartmental tongue surgery (CTS) is a surgical technique that removes an anatomo-functional compartment containing the primary tumor...

BACKGROUND: Opinions regarding the optimal time for the repair of tetralogy of Fallot vary. A debate also exists about the timing of repair for the asymptomatic infant. METHODS: This study included 183 patients with tetralogy of Fallot. All patients were subjected to clinical examination with measurement of oxygen saturation, 12-lead ECG, plain chest x-ray, and complete laboratory investigation. Echocardiography and cardiac catheterisation were indicated if there was an inability to reach diagnosis by echocardiography, suspicion of coronary anomaly, evaluation of distal pulmonary arteries or suspicion of major aorto-pulmonary collaterals...

A new β-class carbonic anhydrase (CA, EC 4.2.1.1) has been cloned, purified and characterized in the genome of the pathogenic bacterium Francisella tularensis responsible of the febrile illness tularemia. This enzyme, FtuβCA, showed a kcat of 9.8 ×10(5)s(-1) and a kcat/KM of 8.9 ×10(7)M(-1)s(-1) for the CO2 hydration, physiological reaction, being one of the most effective β-CAs known to date, with a catalytic activity only 1.68-times lower than that of the human(h) isoform hCA II. A panel of 39 simple aromatic and heterocyclic sulfonamides, as well as clinically used drugs incorporating sulfonamide/sulfamate zinc-binding groups, was used to investigate the inhibition profile of FtuβCA with these classes of derivatives...

Interventional cardiology procedures are constantly increasing in numbers and in quality, especially in developing countries such as Egypt. The numbers and types of procedure now available have driven development in the field and in its accompanying services. The aim of this short report is to present a review of the development of interventional cardiology in Egypt during the period 2010-2015 and the demographic, economic and educational factors that have affected this process. We collected and analysed data provided by different centres and from the distributors of intervention tools for the years 2010 to 2015...

OBJECTIVE: Limited data exist regarding the outcomes of non-cardiac procedures (NCPs) in adult patients after Fontan operations (Fontan patients). METHODS: To compare procedural outcomes after NCPs in Fontan patients with outcomes for two matched control groups: patients with repaired congenital heart disease and biventricular circulation (CHD-BiV) and patients with no heart disease (NHD). We defined cyanosis as oxygen saturation <90% and procedural hypoxia as saturation <80% or a decrease in saturation >10% from baseline...

The intraspecific variability of A. herba-alba and A. campestris essential oils and the evaluation of their antioxidant and antiacetylcholinesterase activities were determined. A. herba-alba essential oil was found rich in camphor (19.61%), α-thujone (19.40%), β-thujone (9.44%), chrysanthenone (9.26%) and trans-sabinyl acetate (8.43%). The major compounds of A. campestris essential oil were germacrene D (16.38%), β-pinene (16.33%) and limonene (9.17%). Significant variation in the essential oil composition was observed among populations of each species...

A comparative force degradation high performance thin layer chromatography (HPTLC) method was developed and validated for some H2-receptor antagonists. The studied H2-receptor antagonists were ranitidine (RAN), nizatidine (NIZ) and famotidine (FAM). The degradation behaviors of the studied H2-receptor antagonists were studied under different stress conditions (hydrolytic, thermal and oxidative) conditions as well as storage conditions according to International Conference on Harmonization (ICH) recommendations...

OBJECTIVE: The aim of this study was to compare the accuracy of flat-panel volume computed tomography (fpVCT) to histopathologic evaluation of excised tumors of the jaws in the detection of the degree of tumor infiltration, the presence of tumor at the resection margins, and the sizes of lesions. STUDY DESIGN: This preliminary study included 47 patients undergoing jaw resection for tumor invasion of bone. The specimens were examined by histology and 3-dimensional fpVCT, and the parameters of bone infiltration, resection margins, and tumor size were determined...

BACKGROUND: Microbial infections are diverse and cause serious human diseases. Candida albicans infections are serious healthcare-related infections that are complicated by its morphological switching from yeast to hyphae, resistant biofilm formation and mixed infections with bacteria. Due to the increase in drug resistance to currently used antimicrobial agents and the presence of undesirable side effects, the need for safe and effective novel therapies is important. Compounds derived from plants are known for their medicinal properties including antimicrobial activities...

INTRODUCTION: Idiopathic nephrotic syndrome (INS) is the most common glomerular disease in children. Immune cell subsets may play a role in pathogenesis of INS. We aimed to assess immunoglobulin G (IgG) and immunoglobulin M (IgM) levels in children with nephrotic syndrome (NS) to predict prognosis of the disease and response to treatment. METHODS: This prospective case control study was done in Pediatric Nephrology Units at Minoufia and Benha University Hospitals, during the period from 1st March 2014 to 30th June 2015...

OBJECTIVES: Takotsubo cardiomyopathy (TTC) is an acute cardiac syndrome simulating myocardial infarction that is characterized by transient wall motion abnormalities in the absence of coronary artery obstruction. Reverse TTC (rTTC) is a recently described variant of TTC. This review defines and compares both forms of TTC, stating their resemblances and differences. METHODS: We conducted a search of the MEDLINE database. Forty-one cases of rTTC met our eligibility criteria and were summarized in a synthesis of the demographic features, clinical characteristics, and laboratory studies...

Anaerobic digestion (AD) is considered an efficient cost-effective technology for sustainable biogas production from lignocellulosic wastes. A novel lignocellulosic degradation microbial consortium (LCDC) was isolated from rotten sawdust, and further used for sawdust pretreatment prior to AD. Results showed that pretreatment of sawdust for 10days led to significant reduction in cellulose, hemicelluloses, and lignin contents by 37.5%, 39.6%, and 56.7%, respectively, with respect to the control. In addition, the pretreatment enhanced cumulative biogas yield, which reached its maximum value of 312...

BACKGROUND: The optimal management strategy for atrial tachyarrhythmia in the Fontan population is unknown. METHODS: Retrospective review of 264 adult Fontan patients with atrial tachyarrhythmia evaluating 3 clinically adopted scenarios: antiarrhythmic drug (AAD) therapy, catheter ablation (CA), and Fontan conversion (FC). These patients were followed up at Mayo Clinic from 1994 to 2014. The study objective was to compare freedom from atrial tachyarrhythmia recurrence (AR) and occurrence of composite adverse events (stroke, heart failure hospitalization, death, or heart transplant) between treatment groups...
