The dependence of BOLD on neuro-vascular coupling leaves it many biological steps removed from direct monitoring of neural function. MRI based approaches have been developed aimed at reporting more directly on brain function. These include: manganese enhanced MRI as a surrogate for calcium ion influx; agents responsive to calcium concentrations; approaches to measure membrane potential; agents ...

We revisit fixed-parameter tractability, fixed-parameter reducibility and kernelizability. The standard formulations of their definitions are enhanced for greater correctness from a structural complexity point of view. Doing so makes clear the distinction between fixed-parameter reducibility and kernelizability. Additionally, these time based definitions are augmented with space based counterpa...

objective: inflammation and oxidative stress is considered to have a crucial role in induction of nephropathy. curcuma longa (c. longa) and nigella sativa (n. sativa) have anti-inflammatory and antioxidant effects. this study was designed to investigate the effect of mixed hydro-alcoholic extract of n.sativa and c. longa on the oxidative stress induced by adriamycin (adr) in rat kidney. materia...

background: social health is considered as a significant dimension of health and, hence, its assessment is vital in health planning. within this context, this study aimed to develop a valid and reliable scale for measuring individual’s social health in iran. to do so, an exploratory sequential mixed method was used. methods: to establish the item pool and primary scale, 30 interviews with exper...
