So my conclusion would be that long term sensitivity must be more than 4.5°C.
But some former lawyers for the department warned on Friday in a letter to Attorney General Michael B. Mukasey that the probe might violate department policy of not initiating such investigations until after an election, citing the "long recognized sensitivity to the role of federal law enforcement officials in elections".
A similar result is expected for Corythoichthys pipefish, given that long wavelength sensitivity is known from other Syngnathids [ 17].
Differences in long wavelength sensitivity have also been found using MSP between species and populations of mollies, which are also in the genus Poecilia [ 87].
Interestingly, molecular data suggest that Xiphophorus and Poecilia species have expanded their LWS opsin repertoires through gene duplication [ 6- 8] corroborating this expansion in long wavelength sensitivity suggested by MSP.
Underlying the relevance of these observations is the long known sensitivity of the heart to β adrenergic stimulation that exerts dynamic physiological control over both chronotropic (rate) and inotropic (strength) properties of cardiac contraction.
Indeed, MSP data have shown considerable variation in retinal long wavelength sensitivity within a single guppy population [ 30, 31], suggesting that relative opsin expression levels are not necessarily fixed between individuals of the same population or species.
The elevated long-wave sensitivity could represent the long-wave tail of the L opsin tuning curve.
However, these methods have various disadvantages including low sensitivity, long assay time, use of toxic substances or unsuitability for field diagnosis.
Up to date, several TP probes for intracellular H2S imaging have been designed, but real-time imaging of endogenous H2S-related biological processes in tissues is hampered due to low sensitivity, long response time and interference from other biothiols.
