An Ulceronecrotic Foot Lesion in a Patient with Essential Thrombocythemia: Successful Treatment with Hydroxyurea
The patient was a 47-year-old woman with a painful ulcer that had appeared on the right 5th toe two weeks before she visited our hospital. Histopathological examination showed that thrombi were present in small blood vessels in the dermis and pancytosis was detected in a blood test, suggesting polycythemia-associated ulceration of the toe. Essential thrombocythemia was diagnosed based on bone marrow puncture and chromosomal test findings. Platelet count and the ulcer were improved by oral hydroxyurea
Resonant Control of Interaction Between Different Electronic States
We observe a magnetic Feshbach resonance in a collision between the ground
and metastable states of two-electron atoms of ytterbium (Yb). We measure the
on-site interaction of doubly-occupied sites of an atomic Mott insulator state
in a three-dimensional optical lattice as a collisional frequency shift in a
high-resolution laser spectroscopy. The observed spectra are well fitted by a
simple theoretical formula, in which two particles with an s-wave contact
interaction are confined in a harmonic trap. This analysis reveals a wide
variation of the interaction with a resonance behavior around a magnetic field
of about 1.1 Gauss for the energetically lowest magnetic sublevel of
Yb, as well as around 360 mG for the energetically highest magnetic
sublevel of Yb. The observed Feshbach resonance can only be induced
by an anisotropic inter-atomic interaction. This novel scheme will open the
door to a variety of study using two-electron atoms with tunable interaction.Comment: 5 pages, 5 figure
Global Aerosol Direct Radiative Effect from CALIOP and C3M
Aerosols are responsible for the largest uncertainties in current estimates of climate forcing. These uncertainties are due in part to the limited abilities of passive sensors to retrieve aerosols in cloudy skies. We use a dataset which merges CALIOP observations together with other A-train observations to estimate aerosol radiative effects in cloudy skies as well as in cloud-free skies. The results can be used to quantify the reduction of aerosol radiative effects in cloudy skies relative to clear skies and to reduce current uncertainties in aerosol radiative effects

Improvement of teaching methods and student learning status in teacher training course II â Topics in teaching Relative Value
We would like to explain our concrete plans on the pre-service of mathematics education methodology in teacher training course of university. It is difficult for many pupils at elementary school to understand on Relative Value in Japan. Students at university, who want to be teachers, donât understand Relative Value, sufficiently, too. We have taught the new teaching methods to students. They understood the meaning of Relative Value and learned how to teach it to pupils
Cutaneous Small Vessel Vasculitis Accompanied by Pustulosis Palmaris et Plantaris
We present the case of a 64-year-old woman who has suffered from pustulosis palmaris et plantaris for 10 years. At the first examination, many erythematous lesions with purpura, blood crusts, and blisters were present in the lower legs and dorsum of the feet. Painful swelling in the sternal region and dorsal pain were also noted. Elevation of the CRP and myogenic enzyme levels, and liver and renal dysfunctions were noted on blood testing. Histopathologically, leukocytoclastic vasculitis was noted in small blood vessels in the whole dermal layers, and deposition of IgM and C3 in the vascular wall was detected by the direct immunofluorescence techniques. Based on these findings, cutaneous small vessel vasculitis was diagnosed. Because the patient complained of a toothache during the clinical course, an X-ray examination was performed. On pantomography, a radicular cyst and apical periodontitis were noted. The tooth symptoms changed with exacerbation and remission of the skin symptoms. These findings indicate that odontogenic infection is very likely to be a cause of cutaneous small vessel vasculitis in a manner similar to pustulosis palmaris et plantaris
Ueber den Einfluss des Tetanustoxins auf die elektrische Bewegung der Lipoidteilchen aus dem Zentralnervensystem
Wenn man die obenerwĂ€hnten Ansichten zusammenfasst, so kommt man zum folgenden Schlusse: 1. Wenn man das Tetanusgift einem Tiere wie Meerschweinchen, Kaninchen, Huhn, Taube und Schildkröte injiziert, so verĂ€ndert sich die elektrische Ladung der Lipoidteilchen aus den Zentralorganen. 2. Solche VerĂ€nderug vermehrt bei Meerschweinchen, Kaninchen und Schildkröte die elektrisch negative Ladung und setzt bei Huhn und Taube die negative Ladung herab. 3. Wenn man das Tetanusgift direkt auf die Lipoidteilchen aus dem Genirn und RĂŒckenmark des Normaltieres einwirken lĂ€sst, so setzt es die elektrisch negative Ladung der Lipoidteilchen nach und nach herab, um endlich den elektrischen Neutralpunkt zu erreichen. Wenn man aber eine grosse Menge Giftlösung mit den Lipoidteilchen bei dem Kaninchen vermischt, bei welchem sich durch die Giftinjektion seine elektrisch negative Ladung vermehrt, so tritt eine zeitweilige Vermehrung der Ladung auf und geht die negative Ladung danach mit Verlauf der Zeit nach und nach herab, was wahrscheinlich auf der Wirkung des im Tetanusgift enthaltenen Ammoniumsulfates beruht. Daher kann man auf die Erscheinung keinen grossen Wert legen. Bei der Taube, bei welcher die elektrisch negative Ladung durch die Giftinjektion herabgesetzt wird, vermindert sich die Ladung von Anfang an. 4. Wenn man die Lipoidteilchen aus dem Gehirn und RĂŒckenmark des Normaltieres in 1%, 3%, und 5%ige wĂ€sserige Lösung von Ammoniumsulfat bringt, so wird die eigentĂŒmliche Ladung der Lipoidteilchen herabgesetzt. Je grösser die Menge von Ammoniumsulfat wird, desto deutlicher wird immer die Herabsetzung. 5. Die Verbindungskraft des Tetanusgiftes mit den Nervenzellen oder den Nervenfasern ist sehr verschieden je nach der Tierspezies. Bei SĂ€ugetieren und Schildkröten ist diese Kraft mehr oder weniger bedeutend, wĂ€hrend sie beim Vogel nur sehr schwach oder so gut wie gar nichts ist. Es ist wahrscheinlich ein Moment, dass der Vogel immun gegen Tetanus ist. Obschon das Gift bei der Schildkröte krĂ€ftig mit dem Gehirn und RĂŒckenmark sich verbindet, so vermag das Tier, von Natur unempfĂ€nglich gegen Tetanusgift zu sein
