Magnetic susceptibility (χ) measurements are widely used for the evaluation of soil profile development. Fourteen soil profiles were studied in a relatively wide range of climatic conditions in Fars Province. Citrate-bicarbonate-dithionite (CBD) extraction and micro CT-Scan images were used to evaluate the source of magnetic susceptibility. The results showed that soil samples lost 23 to 91 per...
Background: CBD stones are the commonest cause of obstructive jaundice and cholangitis and in elderly patients with major underlying disease has a high incidence of mortality. Materials and Methods: In this study, we overviewed 200 patients with CBD stones which treated with cholecystectomy and Endoscopic sphinctrotomy or cholecystectomy and open CBD Exploration, and compare them for surgery c...
Our recent work has shown that cannabidiol (CBD) exhibits the most potent direct inhibition of human cytochrome P450 1A1 (CYP1A1) among the CYP enzymes examined. However, the mechanism underlying this CBD inhibition remains to be clarified. Thus, to elucidate the structural requirements for the potent inhibition by CBD, the effects of CBD and its structurally related compounds on CYP1A1 activit...
UNLABELLED Laparoscopic common bile duct exploration (LCBDE) has been found to be a safe, efficient and cost-effective treatment for choledocholithiasis. Following LCBDE, the clearance may be ascertained by a cholangiogram or choledochoscopy. The common bile duct (CBD) may be closed primarily with or without a stent in situ or may be drained by means of a T-tube or a biliary enteric anastomosis...
Introduction: Common Bile Duct stones (CBD) are found in approximately 16% of the patients undergoing Laparoscopic cholecystectomy (LC). Till recently, the gold standard for treating CBD stones was endoscopic removal, if that failed, then open surgery. However, in the laparoscopic era, the best treatment for CBD stones is a matter of debate and it continues to evolve. The objective of the prese...
BACKGROUND Dilated common bile duct (CBD) without obvious cause is a not uncommon finding on magnetic resonance cholangiopancreatography (MRCP). The aim of this study was to evaluate the diagnostic performance of endoscopic ultrasound (EUS) in patients with unexplained dilated CBD on MRCP. METHODS Patients referred for EUS evaluation of a dilated CBD were retrospectively analyzed with respect...
MMP-2 (matrix metalloproteinase 2) contains a CBD (collagen-binding domain), which is essential for positioning gelatin substrate molecules relative to the catalytic site for cleavage. Deletion of the CBD or disruption of CBD-mediated gelatin binding inhibits gelatinolysis by MMP-2. To identify CBD-binding sites on type I collagen and collagen peptides with the capacity to compete CBD binding o...
PURPOSE To study the optic nerve head (ONH) morphology of patients with Leber's hereditary optic neuropathy (LHON) in a large family from Brazil carrying the 11778/ND4 mutation and in a case series of unrelated Italian families bearing different mitochondrial DNA (mtDNA) pathogenic mutations. METHODS Enrolled in the study were 15 LHON-affected patients (LHON-affected) and 45 LHON unaffected m...
Mode I fracture toughness (KIC) is an intrinsic material property that quantifies its resistance to tensile propagation. The International Society for Rock Mechanics has endorsed four methods determine the KIC of rock, namely, short rod, chevron bend, cracked notched Brazilian disc, and semi-circular bend (SCB) methods. In this study, we compare results SCB technique with those recently propose...
