Therapeutic uses of inorganic nitrite and nitrate - from the past to the future
No full textPotential carcinogenic effects, blue baby syndrome, and occasional intoxications caused by nitrite, as well as the suspected health risks related to fertilizer overuse, contributed to the negative image that inorganic nitrite and nitrate have had for decades. Recent experimental studies related to the molecular interaction between nitrite and heme proteins in blood and tissues, the potential role of nitrite in hypoxic vasodilatation, and an unexpected protective action of nitrite against ischemia/reperfusion injury, however, paint a different picture and have led to a renewed interest in the physiological and pharmacological properties of nitrite and nitrate. The range of effects reported suggests that these simple oxyanions of nitrogen have a much richer profile of biological actions than hitherto assumed, and several efforts are currently underway to investigate possible beneficial effects in the clinical arena. We provide here a brief historical account of the medical uses of nitrite and nitrate over the centuries that may serve as a basis for a careful reassessment of the health implications of their exposure and intake and may inform investigations into their therapeutic potential in the future
Reflections of a Jewish, Lesbian Author

No full textRecent events in the Mediterranean call up for a radical questioning of our categories and
representations. Sinking boats and emergency landings, reception policies and detention centres,
crossings, deviations and refoulements symbolize an era when mobility is fatally related to security
policies and new biopolitical regimes. Migrant bodies crossing the Mediterranean address a demand
and a challenge that cultural geography is urged to accomplish. The aim of this paper is therefore to
rethink spatiality in an ethical sense. Drawing on the philosophy of Emmanuel Lévinas and Judith
Butler, we will try to imagine a new spatiality starting from bodies, displacements, and the complex
open weave produced and reproduced by them. A precarious space, where singular bodies expose
themselves to the event of the other, revealing how vulnerability can lead to new forms of resistance
and political action
Integration of vestibular and proprioceptive signals for spatial updating
No full textFrissen I, Campos JL, Souman JL, Ernst MO. Integration of vestibular and proprioceptive signals for spatial updating. Experimental Brain Research. 2011;212(2):163-176.Spatial updating during self-motion typically involves the appropriate integration of both visual and non-visual cues, including vestibular and proprioceptive information. Here, we investigated how human observers combine these two non-visual cues during full-stride curvilinear walking. To obtain a continuous, real-time estimate of perceived position, observers were asked to continuously point toward a previously viewed target in the absence of vision. They did so while moving on a large circular treadmill under various movement conditions. Two conditions were designed to evaluate spatial updating when information was largely limited to either proprioceptive information (walking in place) or vestibular information (passive movement). A third condition evaluated updating when both sources of information were available (walking through space) and were either congruent or in conflict. During both the passive movement condition and while walking through space, the pattern of pointing behavior demonstrated evidence of accurate egocentric updating. In contrast, when walking in place, perceived self-motion was underestimated and participants always adjusted the pointer at a constant rate, irrespective of changes in the rate at which the participant moved relative to the target. The results are discussed in relation to the maximum likelihood estimation model of sensory integration. They show that when the two cues were congruent, estimates were combined, such that the variance of the adjustments was generally reduced. Results also suggest that when conflicts were introduced between the vestibular and proprioceptive cues, spatial updating was based on a weighted average of the two inputs
A quantitative description of fluorescence excitation spectra in intact bean leaves greened under intermittent light
No full textPfündel E, Baake E. A quantitative description of fluorescence excitation spectra in intact bean leaves greened under intermittent light. Photosynthesis Research. 1990;26(1):19-28.We present a simple approach for the calculation of in vivo fluorescence excitation spectra from measured absorbance spectra of the isolated pigments involved. Taking into account shading of the pigments by each other, energy transfer from carotene to chlorophyll a, and light scattering by the leaf tissue, we arrive at a model function with 6 free parameters. Fitting them to the measured fluorescence excitation spectrum yields good correspondence between theory and experiment, and parameter estimates which agree with independent measurements. The results are discussed with respect to the origin and the interpretation of in vivo excitation spectra in general
