Circular DNA's from HeLa cell nuclei and mitochondria

An electron microscopic observation was made on the DNA's extracted from purified HeLa cell nuclei, mitochondria, and the whole cell, and fractionated by ethidium bromide-cesium chloride density gradient method or sucrose density gradient method. Nuclear DNA presents mainly long linear DNA derived from fragmented chromosomal DNA. In addition to this, the existence of small circular DNA molecules measuring 0.32 -1.78 &#956;, was confirmed. Mitochondrial DNA was mainly circular DNA, which measured 4.87 &#956; in the mean value of the contour lengths in the highest frequency group, and small circular DNA molecules, measuring 0.3-1.01 &#956; in contour length, were also found in an extremely low frequency.</p

Occurrence of Hyperon Superfluidity in Neutron Star Cores

Superfluidity of $\Lambda$ and $\Sigma^-$ admixed in neutron star (NS) cores is investigated realistically for hyperon ($Y$)-mixed NS models obtained using a $G$-matrix-based effective interaction approach. Numerical results for the equation of state (EOS) with the mixing ratios of the respective components and the hyperon energy gaps including the temperature dependence are presented. These are meant to serve as physical inputs for $Y$-cooling calculations of NSs. By paying attention to the uncertainties of the EOS and the $YY$ interactions, it is shown that both $\Lambda$ and $\Sigma^-$ are superfluid as soon as they appear although the magnitude of the critical temperature and the density region where superfluidity exists depend considerably on the $YY$ pairing potential. Considering momentum triangle condition and the occurrence of superfluidity, it is found that a so-called `` hyperon cooling\rq\rq~(neutrino-emission from direct Urca process including $Y$) combined with $Y$-superfluidity may be able to account for observations of the colder class of NSs. It is remarked that $\Lambda$-hyperons play a decisive role in the hyperon cooling scenario. Some comments are given regarding the consequences of the less attractive $\Lambda\Lambda$ interaction recently suggested by the `` NAGARA event\rq\rq~$^6_{\Lambda\Lambda}$He.Comment: 25 pages, 12figures; final version; will appear in Prog.

Fan-shaped aurora as seen from Japan during a great magnetic storm on February 11, 1958

During a great magnetic storm on Feb 11, 1958, a fan-shaped aurora was photographed at Memambetsu, Hokkaido, Japan – the first and oldest photograph record of auroras observed in Japan, accompanied by many hand-made drawings, thus, portraying a rare opportunity of coexistence between photograph images and hand-made drawings. In fact, the same portrayal reminds us of the great red aurora with fan-shaped white pillars observed during the 1872 and 1770 great magnetic storms. The hand-made sketches, photographs, and the spectral data revealed that the white pillars and red glow of the fan-shaped aurora were dominated by auroral green and red lines, respectively. From the analysis of newly digitized microfilm data and hand-made drawings, we found that the fan-shaped aurora appeared during the peak activity of magnetic storm and moved westward at 0.4 km/s at 400-km altitude at 38°–40° magnetic latitudes, which is consistent with the enhanced convection pattern in the middle latitude at storm time. Such a fan-shaped aurora can fundamentally characterize the middle-latitude evening-to-midnight auroras during great magnetic storms, which show the most destabilized transient appearance of the inner magnetosphere

[総説］Nucleic acids and their components : A requirement for cellular development and immune function

Dietary sources of nucleic acids and their components (nucleosides and nucleotides) have not been considered to be essential for normal growth and development. The liver has an active de novo synthesis of nucleic acid components and supplies them to some tissues such as intestinal epithelium and lymphoid cells which lack the de novo synthesis. However in certain clinical conditions such as infection and surgical stress the requirement of the components increases and the endogenous supply becomes insufficent. In such circumstances, the cells require exogenous sources. The significance of exogenously administered nucleic acids and their components for opitimal function of cellular development and immune response is reviewed.論文http://purl.org/coar/resource_type/c_650

In the article by Tomoda T et al. entitled “A Multicenter, Prospective, Randomized Controlled Trial Evaluating the Efficacy of Rectal Diclofenac and Sublingual Nitroglycerin as a Combined Prophylactic Treatment for Post-ERCP Pancreatitis”, which appeared in the October 2016 issue, Vol. 70, No. 5, pp405-408, the word “nitroglycerin” should be corrected to “nitrate” throughout the manuscript

A model-free predictive control method by ℓ1-minimization

We propose a new predictive control method utilizing a sparse solution of a minimization problem defined by both online and stored input/output data of the controlled system. The conventional predictive control methods generally require a mathematical model of the controlled system to predict an optimal future input to control the system. The mathematical model is usually obtained by applying a standard system identification method to the measured input/output data. The proposed method in this paper requires no mathematical model to predict future control input to achieve the desired output. This model-free control method, also called just-in-time predictive control, was originally proposed by Inoue and Yamamoto in 2004 and simplified by Yamamoto in 2014. In this paper, to develop another simplified method, we formulate an ℓ1-minimization problem. © 2015 IEEE.10th Asian Control Conference, ASCC 2015; Sutera Harbour ResortKota Kinabalu; Malaysia; 31 May 2015 through 3 June 2015; Category numberCFP15832-ART; Code 117644, Article number 724444
