DETECTION OF STRYCHNINE.

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Strychnine and Memory Process

feedback training can lead to large and significant changes in alpha densities when conditions have lowered alpha density below the levels seen spontaneously under optimal conditions. Subjects can acquire volitional control over alpha activity only under conditions which normally lead to decreased densities. Thus, during the initial orientation in the dark, when subjects experiment, but are not...

Strychnine in Fever

Sin,?Mr. Hall, of the Royal Artillery, in the last number of the Gazette, calls attention to the use of strychnine as a substitute for quinine in the treatment of malarious fevers, and " has never yet met with any mention, in books, of this medicine having been given as a substitute for quinine." In the Year Book of the new Sydenham Society for 1862, at page 51, there will be found a record of ...

Modulation of nicotinic acetylcholine receptors by strychnine.

Strychnine, a potent and selective antagonist at glycine receptors, was found to inhibit muscle (alpha1beta1gammadelta, alpha1beta1gamma, and alpha1beta1delta) and neuronal (alpha2beta2 and alpha2beta4) nicotinic acetylcholine receptors (AcChoRs) expressed in Xenopus oocytes. Strychnine alone (up to 500 microM) did not elicit membrane currents in oocytes expressing AcChoRs, but, when applied be...
