Clinical applications of anginin in ophthalmology. I. A case of the arteriosclerotic retinopathy with the retinal venous thrombosis favorably treated with anginin, especially effects of anginin on white sheating of the retinal artery

A case of arteriosclerotic retinopathy associated with retinal venous thrombosis was treated with Anginin and the following results obtained: 1) Visual acuity was improved from 0.03 to 0.7. 2) Retinal hemorrhages were absorbed and pipe-stem sheathing of the branch of retinal artery decrease, with white sheathing remaining partially. 3) It was therefore considered that the pipe-stem sheathing was decreased because Anginin removed venous spasm and improved the blood stream of the branch of the artery, and that the organic changes already established on the arterial wall would remain as white sheathing. 4) Anginin could not prevent retinal veins from changing into white lines. 5) Consequently the authors considered that Anginin may be a drug effectively used for retinal arteriosclerosis and retinal venous thrombosis associated therewith.</p

Photonic-crystal nano-photodetector with ultrasmall capacitance for on-chip light-to-voltage conversion without an amplifier

The power consumption of a conventional photoreceiver is dominated by that of the electric amplifier connected to the photodetector (PD). An ultralow-capacitance PD can overcome this limitation, because it can generate sufficiently large voltage without an amplifier when combined with a high-impedance load. In this work, we demonstrate an ultracompact InGaAs PD based on a photonic crystal waveguide with a length of only 1.7 μm and a capacitance of less than 1 fF. Despite the small size of the device, a high responsivity of 1 A/W and a clear 40 Gbit/s eye diagram are observed, overcoming the conventional trade-off between size and responsivity. A resistor-loaded PD was actually fabricated for light-to-voltage conversion, and a kilo-volt/watt efficiency with a gigahertz bandwidth even without amplifiers was measured with an electro-optic probe. Combined experimental and theoretical results reveal that a bandwidth in excess of 10 GHz can be expected, leading to an ultralow energy consumption of less than 1 fJ/bit for the photoreceiver. Amplifier-less PDs with attractive performance levels are therefore feasible and a step toward a densely integrated photonic network/processor on a chip

Studies on the treatment of keratoconjunctivitis sicca.

Fifteen cases of keratoconjunctivitis sicca (KCS) of unknown etiology were treated with soft contact lenses for the purpose of their bandage effects and moisuture supply. A soft contact lens was worn on one of the eyes of each case but not on the other to compare its effectiveness. New opthalmic drops or contact lens wearers were dropped in both eyes. Furthermore, the KCS-index was worked out on the basis of the complaints of 23 patients of KCS of unknouwn etiology. The indexes before and after treatment were compared. Corneal objective findings were improved in all the eyes wearing soft contact lensen for along period, and seven stopped wearing them although corneal objective findings were much better, because they had some troubles with handlings were much better, because they had some troubles with handling the lenses, because they had lost rhem, or because their visual acuity decreased while wearing the lenses. Forlong term wearing the flattest lenses should be used in the beginning and changed gradually to lenses of greater curvature which are better able to keep their centering. Then immediately after successful fitting, the lenses should be given appropriate refractive power. The new ophthalmic drops for soft contact lens wearers were very much effective as artificial tears to both eyes with and without sofy contact lenses. KCS-indexes were numerical values relating to patients subjective symptoms. KSC-indexes improves by an average of +6.4&#177;7.5 after treatment. On the other hand, KCS-indexes improved by +10.7&#177;7.9 in the group that succeeded in wearing SCL for a long period, and by +7.6&#177;2.1 even in the group that failed. </p

Changes in Knowledge Levels through Lectures on Radiotherapy to Nursing Students in Japan

Background:Recently, the number of patients choosing radiotherapy is increasing in Japan. It is necessary for even nurses to have knowledge of radiotherapy. We measured the degree of awareness with a lecture on how a nursing student can obtain knowledge of radiotherapy.Materials and methods: Forty nursing students who were in their third year and preparing for their national nursing certification in two months were recruited. The 90-min lecture covered a range of topics from general theories to specific concepts. The students were not informed that they would be required to fill a survey at the end of the lecture. This was to avoid bias that could occur from knowing in advance that a survey would be conducted.Results: The following items below were particularly remarkable. The distinction between the radiologist and the radiation oncologist. The radiotherapy is a local therapy. The pain from bone metastasis could be relieved.Conclusion: Students had very little knowledge on radiotherapy before the lecture. the results of this study indicated the need to increase the number of lectures on radiotherapy for nursing as well medical students. As the number of radiotherapy patients increases

Large Population of ALMA Galaxies at z>6 with Very High [OIII]88um to [CII]158um Flux Ratios: Evidence of Extremely High Ionization Parameter or PDR Deficit?

We present our new ALMA observations targeting [OIII]88um, [CII]158um, [NII]122um, and dust continuum emission for three Lyman break galaxies at z=6.0293-6.2037 identified in the Subaru/Hyper Suprime-Cam survey. We clearly detect [OIII] and [CII] lines from all of the galaxies at 4.3-11.8sigma levels, and identify multi-band dust continuum emission in two of the three galaxies, allowing us to estimate infrared luminosities and dust temperatures simultaneously. In conjunction with previous ALMA observations for six galaxies at z>6, we confirm that all the nine z=6-9 galaxies have high [OIII]/[CII] ratios of L[OIII]/L[CII]~3-20, ~10 times higher than z~0 galaxies. We also find a positive correlation between the [OIII]/[CII] ratio and the Lya equivalent width (EW) at the ~90% confidence level. We carefully investigate physical origins of the high [OIII]/[CII] ratios at z=6-9 using Cloudy, and find that high density of the interstellar medium, low C/O abundance ratio, and the cosmic microwave background attenuation are responsible to only a part of the z=6-9 galaxies. Instead, the observed high [OIII]/[CII] ratios are explained by 10-100 times higher ionization parameters or low photodissociation region (PDR) covering fractions of 0-10%, both of which are consistent with our [NII] observations. The latter scenario can be reproduced with a density bounded nebula with PDR deficit, which would enhance the Lya, Lyman continuum, and C+ ionizing photons escape from galaxies, consistent with the [OIII]/[CII]-Lya EW correlation we find.Comment: 20 pages, 18 figures, Accepted for publication in Ap

Problematika Permohonan Grasi Menurut Undang-undang Nomor 22 Tahun 2002

According to executor attorney opinion, no time limit for application clemency, it wills be performing deep constraint on dead punishment execution. Execution of dead punishment also constraint by rule that allows criminal to propose the second clemency application. This constraint still is added by condition that second clemency application is two years of first clemency rejection. Meanwhile according to criminal lawyer reception, with no rule upon, constitute a advantage by criminal dead, since it can propose clemency without time limit for first clemency application and also second application, so execution could be delayed. At Yogyakarta court since year 2002 until now there is no criminal propose clemencies. It is caused, firstly, certain verdict type that could be requested for clemency, secondary by apply clemency cause dead sentence is no postpone except for dead verdict, thirdly most criminal on narcotic and drug abuse case was pleased with first grade verdict

A Homozygous Mutation in UGT1A1 Exon 5 May Be Responsible for Persistent Hyperbilirubinemia in a Japanese Girl with Gilbert’s Syndrome

The UGT1A1 gene encodes a responsible enzyme, UDP-glucuronosyltransferase1A1, for bilirubin metabolism. Many mutations have already been identified in patients with inherited disorders with hyperbilirubinemia, Crigler-Najjar syndrome and Gilbert’s syndrome. In this study, we identified a UGT1A1 mutation in an 8-year-old Japanese girl with persistent hyperbilirubinemia who was clinically diagnosed as having Gilbert’s syndrome. For the mutational analysis of UGT1A1, we performed a full sequence analysis of the gene using the patient’s DNA. She was homozygous for a T to G transversion at nucleotide position 1456 in UGT1A1 exon 5 (c.1456T>G), leading to the substitution of aspartate for tyrosine at position 486 of the UGT1A1 protein (p.Y486D). In conclusion, the homozygous mutation of UGT1A1 may be responsible for persistent hyperbilirubinemia in this patient
