sensitivity

Optical spectrum

.... A light -adapted eye typically has its maximum sensitivity at ~555 nm , in the yellow region of the optical spectrum. Wavelengths visible to the eye are defined by the spectral range of the " optical window ", the region of the electromagnetic spectrum which passes largely unattenuated through the Earth ...

Signal transduction

...necessary. Also, the recipient cell can modify the sensitivity of the receptor, for example by phosphorylation ; also, the variation of the number of receptors can vary the total signal strength in the recipient cell. Signal transduction of transmembrane receptors by structural changes Signal transduction...

Olfaction

...lfaction in the animal kingdom The importance and sensitivity of smell varies among different organisms: most mammals have a good sense of smell, whereas most birds do not. As an exception among birds, olfaction is important in the tubenoses . Among mammals it is well developed in the carnivores and ung...

Magnetic resonance imaging

...ly in the 0.2 tesla range, which decreases their sensitivity but also decreases the Radio Frequency power potentially absorbed by the patient during a protracted operation. Radiation Therapy Simulation Because of MRI's superior imaging of soft tissues, it is now being utilized to specifically locate tumors...

Insulin

... However, more commonly there is a decrease in the sensitivity of cells to insulin (eg, the reduced insulin sensitivity characteristic of Type 2 diabetes), resulting in decreased glucose absorption. In either case, there...

Diabetes mellitus

... type 1, the first recognized form), or decreased sensitivity of body tissues to insulin (diabetes mellitus type 2, the more common form). The former requires insulin injections, while the latter is generally managed with oral medication and only requires insulin if the tablets are ineffective. Patient unde...

Chromatography

...easier to differentiate one peak from another) and sensitivity (tall, narrow peaks can be easier to discriminate from noise than shorter, broader peaks). Solvents used include any miscible combination of water or various organic liquids (the most common are methanol or acetonitrile ). Often, a gradient over...

Albinism

...t is painted white within, rather than black. Such sensitivity generally leads to a dislike of bright lights, but does not prevent people with albinism enjoying the outdoors. They should avoid prolonged exposure to bright sunlight regardless, as their skin is particularly susceptible to sunburn . Genetics I...
