Concomitant Gastric Malignancy and Hepatocellular Carcinoma.

Multiple primary malignant tumors (MPMTs) are two or more separate malignancies found at different sites concurrently. Prior studies have shown that the most common tumor associations in MPMTs are typically between two tumors in the digestive system. We present a case of a male patient in his 60s who initially presented with melena and was found to have a clean-based gastric ulcer on initial endoscopic evaluation.

Age-related changes in anterior cingulate cortex glutamate in schizophrenia: A (1)H MRS Study at 7 Tesla.

The extent of age-related changes in glutamate and other neurometabolites in the anterior cingulate cortex (ACC) in individuals with schizophrenia remain unclear. Magnetic resonance spectroscopy (MRS) at 7 T, which yields precise measurements of various metabolites and can distinguish glutamate from glutamine, was used to determine levels of ACC glutamate and other metabolites in 24 individuals with schizophrenia and 24 matched controls. Multiple regression analysis revealed that ACC glutamate decreased with age in patients but not controls.
