BACKGROUND Memantine attenuates heart stress due cold stress, however, no study focused its effects on liver and adrenal gland. We evaluated its effects on lipid depletion in adrenal gland and glycogen depletion in liver of rats exposed to cold stress. METHODS Male rats divided into 4 groups: 1)Control (CON); 2)Memantine (MEM); 3)Induced cold stress (IH) and; 4)Induced cold stress memantine (...

Background & Aim: Glycyrrhiza L. (Fabaceae) consists of perennial herbs grow in sandy soils with hard lightness. Three species of the genus grow in Iran, among them G. glabra L. has the widest distribution. It is well known in English as Licorice and the root extract includes flavonoids and glycyrrhizin are used widely in medicine, food industry, tobacco products and other ind...

Low-temperature stress induces the expression of a variety of genes in plants. However, the signal transduction pathway(s) that activates gene expression under cold stress is poorly understood. Mutants defective in cold signaling should facilitate molecular analysis of plant responses to low temperature and eventually lead to the identification and cloning of a cold stress receptor(s) and intra...

Bermudagrass is widely utilized in parks, lawns, and golf courses. However, cold is a key factor limiting resource use in bermudagrass. Therefore, it is meaningful to study the mechanism of bermudagrass response to cold. Nitric oxide (NO) is a crucial signal molecule with multiple biological functions. Thus, the objective of this study was to investigate whether NO play roles in bermudagrass re...

mihan is a new bread wheat cultivar originated from the cross between iranian cultivar barakat with the chinese cultivar 90-zhong 87 at karaj research station in 1995-96 cropping season. the f1 plants were grown at karaj in 1996-97 cropping season, furthermore f2-f6 populations and regional preliminary yield nursery were evaluated at ardebil agricultural research station during 1997-2003 croppi...

Alternative splicing plays a major role in expanding the potential informational content of eukaryotic genomes. It is an important post-transcriptional regulatory mechanism that can increase protein diversity and affect mRNA stability. Alternative splicing is often regulated in a tissue-specific and stress-responsive manner. Cold stress, which adversely affects plant growth and development, reg...

Plants, as sessile organisms, can suffer serious growth and developmental consequences under cold stress conditions. Glutathione transferases (GSTs, EC 2.5.1.18) are ubiquitous and multifunctional conjugating proteins, which play a major role in stress responses by preventing oxidative damage by reactive oxygen species (ROS). Currently, understanding of their function(s) during different bioche...
