Little is known about the effect of management practices on net global warming potential (GWP) and greenhouse gas intensity (GHGI) that account for all sources and sinks of greenhouse gas (GHG) emissions in dryland cropping systems. The objective of this study was to compare the effect of a combination of tillage, cropping system, and N fertilization on GWP and GHGI under dryland cropping syste...
BACKGROUND Hepatitis C virus (HCV) infection is frequently associated with B-cell non-Hodgkin's lymphomas. We investigated the prevalence of HCV infection in nongastric marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT) in order to define the relationship between the viral infection and the presenting features, treatment, and outcome. METHODS We retrospectively studied 172 pa...
The expression of the maltose system in Escherichia coli is regulated at both transcriptional and translational levels by the pH of the growth medium (pHo). With glycerol as the carbon source, transcription of malT, encoding the transcriptional activator of the maltose regulon, is weaker in acidic medium than in alkaline medium. malT transcription became high, regardless of the pHo, when glycer...
Primary lymphomas of mucosa associated lymphoid tissue (MALT) are exceedingly rare. We report the case of a 51 year old female diagnosed with primary MALT lymphoma of the gallbladder after cholecystectomy. Further staging workup was negative for metastatic disease. When the disease is localized to the gallbladder, primary MALT lymphomas of the gallbladder carry an excellent prognosis, and surgi...
The expression of the maltose regulon of Escherichia coli is controlled by a transcriptional activator, the product of the malT gene, and is induced by the presence of maltose or maltodextrins in the growth medium. We isolated eight mutants with mutations in malT which lead to constitutive expression of the regulon. The nucleotide sequences of the mutated genes revealed that the eight mutations...
Military logistics planning is a complex process, involving many calculations, satisfaction of constraints, and cooperation amongst many organisational entities that provide services in order to achieve military logistics goals. Multi-Agent Logistics Tool (MALT) is a project aimed at supporting military logistics planning. MALT is being developed using agent technology, where agents represent t...
BACKGROUND In contrast to gastric extranodal marginal zone mucosa associated lymphoid tissue (MALT) lymphomas, there is little consensus on the value and clinical consequences of extensive staging at diagnosis and during follow-up in non-gastric MALT lymphomas. DESIGN AND METHODS Complete clinical information at presentation and during follow-up was collected for 72 patients with non-gastric ...
CONTEXT Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is clearly associated with Helicobacter pylori gastritis and can be cured with anti- H pylori therapy alone. The presence of t(11;18)(q21;q21) translocation is thought to predict a lower response rate to anti- H pylori treatment. OBJECTIVES To study the presence of t(11;18)(q21;q21) genetic translocation and its clinical impact...
OBJECTIVE MALT lymphomas are a group of extranodal indolent lymphomas that usually present as stage IE. To clarify clinical features, treatment alternatives and outcomes, we evaluated 38 patients treated with chemotherapy or radiotherapy between 2000 and 2011. PATIENTS AND METHODS MALT lymphoma patients identified according to WHO classification and treated at KCCC between 2000 and 2011 were ...
PURPOSE Mucosa-associated lymphoid tissue (MALT) lymphoma comprises 7% of all newly diagnosed non-Hodgkin's lymphomas and is therefore among the most common lymphoma entities. Monoclonal gammopathy due to production of a monoclonal immunoglobulin by lymphoma cells is a well-known phenomenon associated with various types of B-cell non-Hodgkin's lymphomas. The objective of the present study was t...
