- Retina and Phototransduction (1) This is a simple overview of the phototransduction and retina structure. It is helpful to trace the light and the flow of information. light hits 11-cis retinal in Rhodopsin (GPCR) and converts it to all trans retinal which causes graded hyperpolarization in the photoreceptors (rods and cones). There are three types of cones that are each sensitive to different wavelength of light. using combination of these cones, we can see the full spectrum of colors. Cone, divergent connection with bipolar cells, high spacial resolution and low sensitivity. Rods, convergent connection with bipolar cells, low resolution and high sensitivity. REMEMBER: Only ganglion cells are able to initiate Action Potential in addition to some Amacrine cells.

- Hyperpolarized-gas MRI of the lung: Can research potential translate to clinical application? Presented at SPIE Medical Imaging 2012 - Dr. John Mugler III Univ. of Virginia (USA) The exceptionally-high magnetic-reso- nance signal provided by hyperpolarized noble gases, such as helium-3 and xe- non-129, permits direct, high-resolution MRI of the airspaces of the lung. Combining this high signal with the inherent flexibility of MRI has resulted in an arsenal of techniques that offer a wealth of regional information on the functional status and structure of the healthy and diseased lung. No other medical-imaging modality can provide comparable information about the lung, which is of particular relevance considering the growing need to address the global impact of pulmonary diseases, such as asthma and chronic obstructive pulmonary disease, on health and quality of life. Despite this impressive and unique potential, which has been amply demonstrated through a wide-range of research studies in animals and humans, hyper- polarized-gas MRI has yet to translate to a clinical imaging tool. Although an outside observer of the field may conclude that lack of translation means lack of sufficient added-value to the evaluation of pulmonary diseases, the true reason is rooted in practical and technical issues, not ultimate potential. On the practi- cal side, commercial and patent issues have blocked widespread dissemination of hyperpolarized-gas technology since the late 1990s. On the technical side, improved image-***ysis approaches are needed to distill imaging ...

- Nitric Oxide 2 - Dr. Ignarro Dr. Ignarro Nitric Oxide Interview Nitric oxide (NO) is produced by many cells in the body; however, its production by vascular endothelium is particularly important in the regulation of blood flow. Because of its importance in vascular function, abnormal production of NO, as occurs in different disease states, can adversely affect blood flow and other vascular functions. NO Biosynthesis NO is produced from the amino acid L-arginine by the enzymatic action of nitric oxide synthase (NOS). There are two endothelial forms of NOS: constitutive NOS (cNOS; type III) and inducible NOS (iNOS; type II). Co-factors for NOS include oxygen, NADPH, tetrahydrobiopterin and flavin adenine nucleotides. In addition to endothelial NOS, there is a neural NOS (nNOS; type I) that serves as a transmitter in the brain and in different nerves of the peripheral nervous system, such as non-adrenergic, non-cholinergic (NANC) autonomic nerves that innervate penile erectile tissues and other specialized tissues in the body to produce vasodilation. Under normal, basal conditions in blood vessels, NO is continually being produced by cNOS. The activity of cNOS is calcium and calmodulin dependent. There are two basic pathways for the stimulation of cNOS, both of which involve release of calcium ions from subsarcolemmal storage sites. First, shearing forces acting on the vascular endothelium generated by blood flow causes a release of calcium and subsequent cNOS activation. Therefore, increases in blood ...

- Electromagnetic curve Brain Cancer Transcranial magnetic stimulation (TMS) is a noninvasive method to cause depolarization or hyperpolarization in the neurons of the brain. TMS uses electromagnetic induction to induce weak electric currents using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain with minimal discomfort, allowing the functioning and interconnections of the brain to be studied. A variant of TMS, repetitive transcranial magnetic stimulation (rTMS), has been tested as a treatment tool for various neurological and psychiatric disorders including migraines, strokes, Parkinson's disease, dystonia, tinnitus, depression and auditory hallucinations.
