    Parkinson's disease, a condition involving progressive deterioration of the nervous system, is at present incurable by conventional medicine. Here we report on a study in which we have evidence of clinical improvement from using a treatment modality recommended by Edgar Cayce, a subtle energy device known as the wet cell battery. Cayce said that the wet cell would transfer vibratory energy into the body, and specifically recommended it for neurological disorders, but there have been no previous clinical studies of this modality. T en participants with Parkinson's disease used the wet cell, a chemical battery, with gold and silver solutions, for a four-month treatment period at home. Nine of the ten people followed the protocol consistently (but none completely or perfectly). They averaged slight to moderate improvement in Parkinson's disease symptoms over four months, based on observations by researchers and subjective questionnaires. Over the long term (three years), one participant obtained almost complete remission of his Parkinson's disease symptoms. Since there was no control group the placebo effect cannot be ruled out. However, many minor symptoms showed interesting improvement in several individuals. For example, two people reported regaining their sense of smell, and one had improved color vision. Several people had more facial emotional expressiveness, and reported reduced tremors

    The purpose of this study was to determine if a subtle energy device, the Cayce Radial Appliance, could improve circulation in the extremities. There were two aspects to the study: a doubleblind, placebo-controlled experiment and a small clinical investigation. In the experiment, 30 subjects were selected for cold extremities, with the criterion that either the hands or the feet had to be below 800 F during the initial measurement session. To measure improvement of circulation, we used digital thermometers to record the temperatures of the thumbs and big toes on both hands and feet. Subjects were instructed to use the appliance 16 times; laboratory measurements were taken during the 1st, 4th and 16th sessions. Skin temperature turned our to be a difficult variable to work with, due to the wide variability in temperature apparently unrelated to the experimental siruation. The strongest results were observed in the 4th session. During session baseline, differences between hand and foot temperatures of the experimental group were significantly greater than those of the control group (t [13,11] 2.49, p '" .02). The 16th session did not yield significant differences between the experimental and control groups. However, in the experimental group, there was a correlation of r (9) -.56 (p '" .07) of hand temperarure increase with the number of days it took to complete the 16 sessions. That is, those subjects who were more consistent in using the appliance may have obtained better results, though statistically the result is only suggestive due to the small sample size. In contrast, in a clinical follow-up study with five subjects and no control group, we found that all subjects had a substantial increase in hand temperature following three sessions on the appliance (Mean increase'" 8.40 F, SO = 3.3). This increase was well in excess of that seen in either the experimental or control groups in the previous study. One important difference was that in the clinical study, use of the appliance was closely supervised, whereas in the blind study most of the appliance sessions were conducted by the subjects alone in their homes

    High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data II: The Spring Equatorial Stripe

    This is the second paper in a series aimed at finding high-redshift quasars from five-color (u'g'r'i'z') imaging data taken along the Celestial Equator by the Sloan Digital Sky Survey (SDSS) during its commissioning phase. In this paper, we present 22 high-redshift quasars (z>3.6) discovered from ~250 deg^2 of data in the spring Equatorial Stripe, plus photometry for two previously known high-redshift quasars in the same region of sky. Our success rate of identifying high-redshift quasars is 68%. Five of the newly discovered quasars have redshifts higher than 4.6 (z=4.62, 4.69, 4.70, 4.92 and 5.03). All the quasars have i* < 20.2 with absolute magnitude -28.8 < M_B < -26.1 (h=0.5, q_0=0.5). Several of the quasars show unusual emission and absorption features in their spectra, including an object at z=4.62 without detectable emission lines, and a Broad Absorption Line (BAL) quasar at z=4.92.Comment: 28 pages, AJ in press (Jan 2000), final version with minor changes; high resolution finding charts available at http://www.astro.princeton.edu/~fan/paper/qso2.htm

    Polymer-tethered glyconanoparticle colourimetric biosensors for lectin binding : structural and experimental parameters to ensure a robust output

    Get PDF
    Glycan–lectin interactions play essential roles in biology; as the site of attachment for pathogens, cell–cell communication, and as crucial players in the immune system. Identifying if a new glycan (natural or unnatural) binds a protein partner, or if a new protein (or mutant) binds a glycan remains a non-trivial problem, with few accessible or low-cost tools available. Micro-arrays allow for the interrogation of 100's of glycans but are not widely available in individual laboratories. Biophysical techniques such as isothermal titration calorimetry, surface plasmon resonance spectrometry, biolayer interferometry and nuclear magnetic resonance spectroscopy all provide detailed understanding of glycan binding but are relatively expensive. Glycosylated plasmonic nanoparticles based on gold cores with polymeric tethers have emerged as biosensors to detect glycan–protein binding, based on colourimetric (red to blue) outputs which can be easily interpreted by a simple UV-visible spectrometer or by eye. Despite the large number of reports there are no standard protocols for each system or recommended start points, to allow a new user to deploy this technology. Here we explore the key parameters of nanoparticle size, polymeric tether length and gold concentration to provide some guidelines for how polymer-tethered glycosylated gold nanoparticles can be used to probe a new glycan/protein interactions, with minimal optimisation barriers. This work aimed to remove the need to explore chemical and nanoparticle space and hence remove a barrier for other users when deploying this system. We show that the concentration of the gold core is crucial to balance strong responses versus false positives and recommend a gold core size and polymer tether length which balances sufficient colloidal stability and output. Whilst subtle differences between glycans/lectins will impact the outcomes, these parameters should enable a lab user to quickly evaluate binding using minimal quantities of the glycan and lectin, to select candidates for further study

    Telecommunication wavelength GaAsBi light emitting diodes

    GaAsBi light emitting diodes containing ∼6% Bi are grown on GaAs substrates. Good room-temperature electroluminescence spectra are obtained at current densities as low as 8 Acm − 2. Measurements of the integrated emitted luminescence suggest that there is a continuum of localised Bi states extending up to 75 meV into the bandgap, which is in good agreement with previous photoluminescence studies. X-ray diffraction analysis shows that strain relaxation has probably occurred in the thicker samples grown in this study

    We present an empirical investigation of the colors of quasars in the Sloan Digital Sky Survey (SDSS) photometric system. The sample studied includes 2625 quasars with SDSS photometry. The quasars are distributed in a 2.5 degree wide stripe centered on the Celestial Equator covering 529\sim529 square degrees. Positions and SDSS magnitudes are given for the 898 quasars known prior to SDSS spectroscopic commissioning. New SDSS quasars represent an increase of over 200% in the number of known quasars in this area of the sky. The ensemble average of the observed colors of quasars in the SDSS passbands are well represented by a power-law continuum with αν=0.5\alpha_{\nu} = -0.5 (fνναf_{\nu} \propto \nu^{\alpha}). However, the contributions of the 3000A˚3000 {\rm \AA} bump and other strong emission lines have a significant effect upon the colors. The color-redshift relation exhibits considerable structure, which may be of use in determining photometric redshifts for quasars. The range of colors can be accounted for by a range in the optical spectral index with a distribution αν=0.5±0.65\alpha_{\nu}=-0.5\pm0.65 (95% confidence), but there is a red tail in the distribution. This tail may be a sign of internal reddening. Finally, we show that there is a continuum of properties between quasars and Seyfert galaxies and we test the validity of the traditional division between the two classes of AGN.Comment: 66 pages, 15 figures (3 color), accepted by A
