Aluminum maltolate (Al-malt) causes neurodegeneration following in vivo exposure, and apoptosis plays a prominent role. The objective of this study was to define the form of cell death induced by Al-malt and to establish an in vitro model system amenable to mechanistic investigations of Al-malt-induced cell death. Neuro-2a cells, a murine neuroblastoma cell line, were treated with Al-malt for 2...

Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal marginal zone B-cell lymphoma and is a distinct subtype of non-Hodgkin's lymphoma.Primary MALT lymphomas can also occur in the oral cavity, although their appearance in this location is rare. The neoplastic cells of which MALT lymphomas are composed express B-cell antigens and show monotypic immunoglobulin expression with...

BACKGROUND Non-Hodgkin lymphoma (NHL) is a well-known hematologic malignancy. The gastrointestinal (GI) tract is the most commonly involved extra nodal site. MALT lymphomas are uncommon, accounting for 5% of all NHL. Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the prototype seen in association with Helicobacter pylori. Colonic MALT lymphoma is rare and comprises only 2.5% of th...

Cases of lymphocytic monoclonal B-cell proliferation such as non-Hodgkin’s lymphomas have been reported in chronically hepatitis C virus (HCV)-infected patients. Lymphomas of the mucosa-associated lymphoid tissue (MALT) type are due to monoclonal proliferation of B cells showing characteristic histopathological features of MALT. Luppi et al1 recently reported an unexpectedly high prevalence of ...

BACKGROUND Development of gastric mucosa associated lymphoid tissue (MALT) lymphoma is thought to be closely associated with host immune reactions to Helicobacter pylori. AIM To investigate humoral immune responses in patients with MALT lymphoma to antigens shared by H pylori and human gastric epithelial cells. METHODS Sera were obtained from H pylori positive patients with MALT lymphoma (n...

Background and Aims. Minimal hepatic encephalopathy (MHE) is diagnosed using neuropsychometric tests or neurophysiological tests that are either inapplicable to illiterate patient population in resource-poor settings or require sophisticated and expensive equipment. The available tests assess discrete domains of mental impairment. Our aim was (a) to design a neuropsychometric test that measures...

OBJECTIVE To explore the relationship between IgH gene rearrangement and orbital MALT (mucose-associated lymphoid tissue) lymphoma removal operation prognosis, and to quantify the effect of IgH gene rearrangement on primary orbital MALT lymphoma prognosis. PATIENTS AND METHODS Fifty-eight patient cases with primary orbital MALT lymphoma were included in this study. Orbital lymphoma specimens ...

Gastric lymphoma of mucosa associated lymphoid tissue (MALT) has characteristic clinicopathological features that are different from nodal-type B cell lymphomas. Before a lymphoma can arise within the stomach, MALT has to be acquired as part of a response to an immunological stimulus. In most instances, gastric MALT is acquired in response to infection by Helicobacter pylori. There are several ...

Primary extranodal malignant non-Hodgkin's lymphoma arising from the mucosa-associated lymphoid tissue (MALT-type lymphoma) represents a subtype of B-cell lymphoid malignancies with distinct clinicopathological features and is often associated with a favorable prognosis. Unlike the situation in nodal non-Hodgkin's lymphoma of B-cell lineage, few data are still available concerning the chromosom...
