Biphasic effects of L-ascorbate on the tumoricidal activity of non-thermal plasma against malignant mesothelioma cells

, 2016
Non-thermal plasma (NTP) is a recently developed technology that elicits a variety of biological effects. This includes cancer cell-specific cytotoxicity, which is mainly attributed to the regional generation of reactive oxygen species (ROS).

Dissecting the osmotic and oxidative stress responses in salt-tolerant and salt-sensitive wheat genotypes under saline conditions

Plant, Soil and Environment
Salinity represents a significant abiotic stress that markedly influences plant growth through osmotic stress induction. Plants commonly undergo osmotic adaptation when subjected to prolonged periods of saline stress.

Serum ascorbic acid concentration in patients with acute Falciparum malaria infection: possible significance

Brazilian Journal of Infectious Diseases
Falciparum malaria infection is associated with significant destruction of erythrocytes. This leads to the release of toxic metabolic products, including oxidant compounds.We measured the serum concentration of the antioxidant, ascorbic acid, in 129 ...
