	Sensitivity of Human Ear
		This incredible sensitivity is enhanced by an effective amplification of the sound signal by the outer and middle ear structures.
		In addition to its remarkable sensitivity, the human ear is capable of responding to the widest range of stimuli of any of the senses.
		The structures of the outer and middle ear contribute to both the remarkable sensitivity and the wide dynamic range of human hearing.

	Thymidine Phosphorylase Mediates the Sensitivity of Human Colon Carcinoma Cells to 5-Fluorouracil -- Schwartz et al. ...
		Human TP has been reported to be identical to the angiogenic factor platelet-derived endothelial cell growth factor (PD-ECGF)(11, 12, 13), and studies indicate that the catalytic activity of the enzyme is indispensable for its angiogenic effects(14, 15, 26).
		Human colon carcinoma HT-29 cells were maintained in RPMI 1640 with 10% heat-inactivated fetal bovine serum and gentamicin, in a humidified CO incubator at 37 °C. Recombinant human thymidine phosphorylase (also known as platelet-derived endothelial cell growth factor) was obtained from Rand Systems (Minneapolis, MN).
		A human ovarian cancer cell line derived from a biopsy of a FUra-resistant tumor was found to have a 70% reduction in TP activity and FdUMP levels compared to a cell line derived from the tumor in the same patient prior to the development of FUra resistance(36).

	Evolution of taste receptor may have shaped human sensitivity to toxic compounds
		It is widely believed that behavioral and dietary choices may have reduced the importance of such chemical perception in higher primates, and particularly in humans.
		The research team analyzed the nucleotide sequence of a human gene encoding a bitter-taste receptor that mediates recognition of a class of naturally ubiquitous, but toxic, cyanide-releasing compounds.
		By analyzing sequences from a large sample of individuals representing 60 human populations, the researchers found evidence that specific variants of the receptor gene have been strongly favored in the early stages of human evolution.

	Maximum Sensitivity Region of Human Hearing (Site not responding. Last check: 2007-09-17)
		This is associated with the resonance of the auditory canal.
		There is another enhanced sensitivity region at about 13,500 Hz which may be associated with the third harmonic resonance of the auditory canal.
		The maximum sensitivity regions of human hearing can be modeled as closed tube resonances of the auditory canal.

	Sensitivity (human) - Wikipedia, the free encyclopedia
		This article is about the human feeling of insensitivity.
		The sensitivity or insensitivity of a human, often considered with regard to a particular kind of stimulus, is the strength of the feeling it results in, in comparison with the strength of the stimulus.
		A person with sensitive skin, which easily becomes painful or inflamed.

	PHOTOPIC LUMINOUS EFFICIENCY FUNCTION OF THE HUMAN RETINA
		The complete spectral sensitivity of the human eye is shown in the following figure under a variety of conditions.
		The darkest area is the region generally described as the scotopic spectral sensitivity function or frequently the "scotopic luminous efficiency function." The heavy line enclosing the scotopic area and the lighter gray area on the right defines the photopic spectral sensitivity function or the "photopic luminous efficiency function.
		The common wisdom has been that the human eye has no ultraviolet sensitivity and that its response to ultraviolet light was due to fluorescence within the eye.

	Effects of discontinuation of zidovudine treatment on zidovudine sensitivity of human immunodeficiency virus type 1 ...
		This reduction is due to mutations causing amino acid substitutions at five codons (41, 67, 70, 215, and 219) on the reverse transcriptase enzyme of HIV.
		Sensitivity could be determined for six isolate pairs: one showed a decline in the 50% inhibitory zidovudine concentration after therapy discontinuation; four pairs did not show a change.
		This study of isolates from a small group of individuals at different stages of disease, who had been taking zidovudine for 1 to 2 years, shows that a period of 1 year without zidovudine may be required to achieve a change from a mutant or mixed virus population to a wild-type virus population.

	Reflections on the Ethos of the Human Body in Works of Artistic Culture
		The artistic objectivation [sic] of the human body in its male and female nakedness, in order to make it first of all a model and then the subject of the work of art, is always to a certain extent a going outside of this original and, for the body, its specific configuration of interpersonal donation.
		The process of refining personal human sensitivity is certainly a factor and fruit of culture.
		In this way, in the processes of human culture understood in the wide sense, we note—even in man's state of hereditary sinfulness—quite an explicit continuity of the nuptial meaning of the body in its masculinity and femininity.

	Electrostatic Discharge Association
		Damage to an ESDS device by the ESD event is determined by the device's ability to dissipate the energy of the discharge or withstand the current levels involved.
		The Human Body Model is the oldest and most commonly used model for classifying device sensitivity to ESD.
		They allow easy grouping and comparing of components according to their ESD sensitivity and the classification gives you an indication of the level of ESD protection that is required for the component.

	Human Vision
		The human vision system perceives images in colour using receptors on the retina of the eye which respond to three relatively broad colour bands in the regions of red, green and blue (RGB) in the colour spectrum (red, orange, yellow, green, blue, indigo, violet).
		The vertical scale is the contrast sensitivity of human vision, which is the ratio of the maximum visible range of intensities to the minimum discernible peak-to-peak intensity variation at the specified frequency.
		A final feature of human vision, which is useful for compression, is that the contrast sensitivity to a given pattern is reduced in the presence of other patterns (activity) in the same region.

	Color, Part I: Human Perception
		I'll first discuss the human notion of color (this month), and next move into why color is such a vital measurement in astronomy.
		However, for most people, red cones are sensitive over a broad range of wavelengths from 0.4 to 0.8 microns and peak at about 0.58 microns; green cones have sensitivity over the same range, but peak at about 0.54 microns and have a relative shift over the range of typically 0.03 microns.
		In your article you explain that the red cones are sensitive at the shortest visible wavelengths, and that this explains why violet appears to us to be a mixture of red and blue light, even though the...

	Electromagnetic Field Sensitivity
		Of the 75, 25 had no reactions to blanks, whereas 50 did, and thus were discarded from the study; even though we felt that some of the reactions to blanks might be evidence of delayed reaction to previous frequencies, or prolonged response to the previous positive challenge, as well as true placebo reactions.
		As a result of the weak field levels and short exposure time, the responses were mild except in two patients whose symptoms were so severe (e.g., drop attack, severe itching) that they received intravenous vitamin C, magnesium, and oxygen as a result of the prolonged and delayed reactions.
		It is clear that EMF sensitivity is a real phenomenon in some environmentally sensitive patients, because some had consistent reactions while none of the controls did.

	Human Hearing: Amplitude Sensitivity Part 1
		Much is made of the ear’s sensitivity at the mid and upper-mid range portions of the audible spectrum (as well it should be), but the realities presented by the ELLC all add up to the requirement of low-level LF distortion that cannot be ignored either, where it comes to the accurate reproduction of music.
		And that’s just as sensitive as the ear needs to be: were it any more sensitive than that, we’d be treated to the never-ending white noise of molecular density fluctuations, or Brownian movement.
		The resultant range is owing to varying methodologies used by the researchers and, of course, the response of the human hearing apparatus to the applied acoustic signals.

	Electrostatic Discharge Association: Fundamentals of ESD
		In Part Two of this series, we indicated that a key element in a successful static control program was the identification of those items (components, assemblies, and finished products) that are sensitive to ESD and the level of their sensitivity.
		One of the most common causes of electrostatic damage is the direct transfer of electrostatic charge through a significant series resistor from the human body or from a charged material to the electrostatic discharge sensitive (ESDS) device.
		Device failure models and device test methods define the sensitivity of the electronic devices and assemblies to be protected from the effects of ESD.

	Improved Photometer
		The photometer measures only a third of the visual spectrum and is blind to the remaining two/thirds. Now ask any 100 pro photographers whether the sensitivity of their $500 light meter is based on the sensitivity of film or on the sensitivity of the human brain? Careful now, it could be a trick question.
		Two primary curves for human spectral sensitivity have been standardized by means of the psychophysical techniques of brightness equivalence matching as a function of radiance and wavelength.
		The CIE adopted the CIE standard photopic observer in 1931 for the fully light-adapted human observer and the CIE standard scotopic observed in 1951 for the dark-adapted human observer.

		With single-blind, placebo-controlled screening challenges, 100 subjects with asthma (30 subjects with a history of Oriental restaurant asthma attacks; 70 subjects with a negative history) were challenged with 2.5 g of MSG.
		MSG challenges in subjects with and without a perceived sensitivity to MSG failed to induce signs or symptoms of asthma.
		Those who had a history of oriental asthma attacks found that their problems were not a result of MSG, but were able to identify other causes, including food allergies and heartburn caused by overeating.
