Three coccoid and two filamentous cyanobacterial strains were isolated from phototrophic biofilms exposed to intense solar radiation on lithic surfaces of the Parasurameswar Temple and Khandagiri caves, located in Orissa State, India. Based on to their morphological features, the three coccoid strains were assigned to the genera Gloeocapsosis and(More)
UNLABELLED The human T-cell leukemia virus type 1 (HTLV-1) is a complex human retrovirus that causes adult T cell leukemia and of HTLV-associated myelopathy/tropical spastic paraparesis. The mRNA of some complex retroviruses, including the human and simian immunodeficiency viruses (HIV and SIV), can initiate translation using a canonical cap-dependent(More)
BACKGROUND There is a lack of prospective, randomized studies comparing the diagnostic yield and complication rates of 22-gauge and 25-gauge needles during EUS-FNA of solid pancreatic masses. OBJECTIVES Our primary aim was to compare the diagnostic yield of 22-gauge and 25-gauge needles. Secondary aims included determining the number of needle passes(More)
BACKGROUND Endoscopic ultrasound with fine needle aspiration (EUS-FNA) is used for the diagnosis of pancreatic malignancy. However, there are limited data as to patient preferences regarding the delivery of cancer diagnoses. OBJECTIVE This study aimed to assess if patients had met the endosonographer before their EUS, their suspicion of having cancer, and(More)
BACKGROUND Pancreatic neuroendocrine tumours are uncommon neoplasms which may rarely be cystic. Differentiation from other more common cystic neoplasms may be difficult. AIMS To describe the morphologic, cytologic, and cyst fluid characteristics of cystic pancreatic neuroendocrine tumours. METHODS Retrospective analysis of consecutive patients referred(More)
BACKGROUND Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are complementary procedures in the evaluation of obstructive jaundice. GOALS To determine the feasibility, accuracy, and safety of the combined performance of EUS-guided fine needle aspiration (FNA) and ERCP with biliary stenting in patients with obstructive(More)
Cyanobacterial extracellular polymeric substances (EPS) are heteropolysaccharides that possess characteristics suitable for industrial applications, notably a high number of different monomers, strong anionic nature and high hydrophobicity. However, systematic studies that unveil the conditions influencing EPS synthesis and/or its characteristics are(More)
Two-stage process based on photofermentation of dark fermentation effluents is widely recognized as the most effective method for biological production of hydrogen from organic substrates. Recently, it was described an alternative mechanism, named capnophilic lactic fermentation, for sugar fermentation by the hyperthermophilic bacterium Thermotoga(More)
Exopolysaccharides (EPSs) are an important class of biopolymers with great ecological importance. In natural environments, they are a common feature of microbial biofilms, where they play key protective and structural roles. As the primary colonizers of constrained environments, such as desert soils and lithic and exposed substrates, cyanobacteria are the(More)
GOALS To determine the prevalence of irritable bowel syndrome (IBS) in subjects with gastroesophageal reflux disease (GERD) compared with non-GERD controls. STUDY Two hundred subjects were identified from a list of Cedars-Sinai Medical Foundation patients and gastroenterology motility practice subjects with and without a potential diagnosis of GERD.
