Antineoplastic effects of cassava-cyanide extract on human glioblastoma (LN229) cells.

Several natural compounds reduce tumour cell growth and metastasis by inducing programmed cell death. Cassava (Manihot esculenta Crantz) contains cyanogenic glycosides such as, linamarin and lotaustralin, can be enzymatically cleaved by linamarase to release hydrogen cyanide (HCN), which can have therapeutic benefits against hypertension, asthma, and cancer. We have developed a technology for isolating bio-active principles from cassava leaves.

Development of Tetramethylenedisulfotetramine (TETS) Hapten Library: Synthesis, Electrophysiological Studies, and Immune Response in Rabbits.

There is a need for fast detection methods for the banned rodenticide tetramethylenedisulfotetramine (TETS), a highly potent blocker of the γ-aminobutyric acid (GABA ) receptors. General synthetic approach toward two groups of analogues was developed. Screening of the resulting library of compounds by FLIPR or whole-cell voltage-clamp revealed that, despite the structural differences, some of the TETS analogues retained GABA receptor inhibition; however, their potency was an order of magnitude lower.

Knee cartilage T2 characteristics and evolution in relation to morphologic abnormalities detected at 3-T MR imaging: a longitudinal study of the normal control cohort from the Osteoarthritis Initiative.

Purpose: To determine the frequency of degenerative knee morphologic abnormalities in asymptomatic individuals by using 3-T magnetic resonance (MR) imaging and to investigate the characteristics and evolution of cartilage T2 values in relation to morphologic abnormalities with a longitudinal study.

Materials And Methods: The study was approved by the institutional review board and was compliant with HIPAA. Ninety-five asymptomatic subjects aged 45-78 years who were free of risk factors for osteoarthritis (OA) were selected from the Osteoarthritis Initiative normal control cohort and examined with radiography and 3-T MR imaging.

Treating hepatitis C in the prison population is cost-saving.

Unlabelled: The prevalence of chronic hepatitis C infection in U.S. prisons is 12% to 31%.

Hepatitis B prophylaxis in patients undergoing chemotherapy for lymphoma: a decision analysis model.

Unlabelled: Hepatitis B reactivation is a major cause of morbidity and mortality in patients undergoing chemotherapy for lymphomas. These patients may experience direct liver-related complications or reduced cancer survival because of interruptions in chemotherapy. Our aim was to compare the costs and outcomes of 2 different chronic hepatitis B management strategies.
