Tea waste was used to successfully synthesize magnetic nanoparticles (TWMNPs). In this investigation, Pb (II) eliminated by tea modified with magnetite (TWMNPs) investigated. To prepare the TWMNPs, FeCl3.6H2O dissolved in double distilled water (DDW) and 20 g of pulp added slowly stirred, after 30 min TWMNPs adsorbent were separated through an external field washed three times ethanol then drie...

BACKGROUND AND STUDY AIMS Colorectal endoscopic submucosal dissection (ESD) is an attractive method for en bloc resection of larger flat neoplastic lesions. Experience with this method is limited in the Western World. PATIENTS AND METHODS A total of 182 consecutive flat or sessile colorectal lesions (cecum n = 43; right-sided colon n = 65; left-sided colon n = 11, rectum: n = 63) with a size ...

BACKGROUND Necrotizing pancreatitis is a life-threatening presentation of acute pancreatitis. The mortality of 20-80% initially depends on the persistence of organ failure and systemic inflammatory response syndrome (SIRS) and, in the later course of the disease, on secondary infection of the necrosis. The questions whether prophylactic antibiotics aiming to prevent this infection should be adm...

INTRODUCTION Probiotics may benefit irritable bowel syndrome (IBS) symptoms, but randomised controlled trials (RCTs) have been conflicting; therefore a systematic review was conducted. METHODS MEDLINE (1966 to May 2008), EMBASE (1988 to May 2008) and the Cochrane Controlled Trials Register (2008) electronic databases were searched, as were abstracts from DDW (Digestive Diseases Week) and UEGW...

BACKGROUND AND STUDY AIMS A new 25-gauge (G) endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) device (EchoTip ProCore; Cook Medical, Bloomington, Indiana, USA) has been developed, which features a hollowed-out reverse bevel to trap core samples. However, data on the differences between the diagnostic yield of the 25G EchoTip ProCore and that of a 22G standard needle are limited. ...

BACKGROUND During normal pregnancy the cervix has a load bearing function. The cervical tissue consists mainly of an extracellular matrix (ECM) rich in collagen; important for the biomechanical properties. The aim of the present study was to evaluate how the biomechanical strength of samples from the distal cervix is associated with collagen content in relation to age and parity. This study dem...

Antioxidative potential of Aloe was studied in mice exposed to different doses of gamma radiation. In this study, adult male Swiss albino mice were divided in six groups (I, II, III, IV, V and VI). Group I and II contained sham irradiated (normal) and Aloe alone treated animals respectively. Each group from III-VI contained an experimental set in which Aloe extract was administered orally at th...

BACKGROUND The nonselective 5-HT(4) receptor agonists, cisapride and tegaserod have been associated with cardiovascular adverse events (AEs). AIM To perform a systematic review of the safety profile, particularly cardiovascular, of 5-HT(4) agonists developed for gastrointestinal disorders, and a nonsystematic summary of their pharmacology and clinical efficacy. METHODS Articles reporting da...
