Chronic low level arsenic exposure evokes inflammatory responses and DNA damage.

The cross-sectional study investigated the impact of chronic low level arsenic (As) exposure (11-50μg/L) on CD14 expression and other inflammatory responses in rural women of West Bengal enrolled from control (As level <10μg/L; N, 131) and exposed area (As level 11-50μg/L, N, 142). Atomic absorption spectroscopy revealed that As level in groundwater was higher in endemic areas (22.93±10.

Chronic low-level arsenic exposure reduces lung function in male population without skin lesions.

Objectives: The respiratory effects of chronic low-level arsenic exposure from groundwater have been investigated in West Bengal, India.

Methods: The participants (834 non-smoking adult males) were subdivided in two groups: an arsenic-exposed group (n = 446, mean age 35.3 years) drinking arsenic-contaminated groundwater (11-50 μg/L) and a control group of 388 age-matched men drinking water containing <10 μg/L of arsenic.

A novel synthetic oleanane triterpenoid suppresses adhesion, migration, and invasion of highly metastatic melanoma cells by modulating gelatinase signaling axis.

A methyl derivative natural triterpenoid amooranin (methyl-25-hydroxy-3-oxoolean-12-en-28-oate, AMR-Me) has been found to possess antiproliferative, proapoptotic, and antiinflammatory effects against established tumor cells. Large-scale synthesis of pure AMR-Me has eliminated the need of the natural phytochemical for further development of AMR-Me as an anticancer drug. Metastatic melanoma is a fatal form of cutaneous malignancy with poor prognosis and limited therapeutic options.
