BACKGROUND It is a widespread belief in Asian countries that mung bean soup (MBS) may afford a protective effect against heat stress. Lack of evidence supports MBS conferring a benefit in addition to water. RESULTS Here we show that vitexin and isovitexin are the major antioxidant components in mungbean (more than 96% of them existing in the bean seed(More)
The dynamin family of GTP-binding proteins has been implicated as playing an important role in endocytosis. In Drosophila shibire, mutations of the single dynamin gene cause blockade of endocytosis and neurotransmitter release, manifest as temperature-sensitive neuromuscular paralysis. Mammals express three dynamin genes: the neural specific dynamin I,(More)
Although abnormal cell growth in arterial vessel walls underpins vascular remodeling in high blood pressure, the molecular basis of the abnormality in hypertension has not been fully defined. Here, we report that in the aorta of spontaneously hypertensive rats, telomerase is selectively activated and telomeres are lengthened, in vivo and in vitro.(More)
T aking advantage of exceptional attributes, such as being easy-to-operate, economical, sensitive, portable, and simple-to-construct, in recent decades, considerable attention has been devoted to the integration of recognition elements with electronic elements to develop electrochemical sensors and biosensors.Various electrochemical devices, such as(More)

All members of the IEEE are eligible for membership in the Society and will receive this TRANSACTIONS upon payment of(More)
Dynamin and G-proteins both are guanosine triphosphate (GTP) binding proteins, with dynamin active in cellular membrane trafficking and G-proteins in intracellular signal transduction. Here we demonstrate that dynamin physically and functionally interacts with G-protein betagamma-subunits in neuroendocrine GH4C1 cells, on stimulation with(More)
The objective of this study was to identify the effects of exogenous putrescine on photosynthetic performance and heat dissipation capacity in cucumber seedlings under salt stress. The stress of 75 mM NaCl for 7 days caused a significant decrease in net photosynthetic rate (P N ). The experiment employed a chlorophyll fluorescence imaging technique and(More)
Antigen-dependent stimulation of T cells plays a critical role in adaptive immunity and host defense. Activation of major histocompatibility complex II (MHC II) molecules, dictated by Class II transactivator (CIITA), is considered a pivotal step in this process. The mechanism underlying differential regulation of CIITA activity by the post-translational(More)
Dehydrins (DHNs), group 2 of late embryogenesis abundant (LEA) proteins, are up-regulated in most plants during cold, drought, heat, or salinity stress. All DHNs contain at least one K-segment, which is believed to play a significant role in DHN function by forming an amphipathic helix. In previous studies, wzy2, an YSK2-type DHN gene, was isolated from the(More)
DNA damage activates checkpoint controls which block progression of cells through the division cycle. Several different checkpoints exist that control transit at different positions in the cell cycle. A role for checkpoint activation in providing resistance of cells to genotoxic anticancer therapy, including chemotherapy and ionizing radiation, is widely(More)
