It has been known that most patients with Korean Hemorrhagic Fever (KHF) were recovered without any significant renal complication. But several cases of renal hypertension, chronic pyelonephritis, and chronic renal failure after KHF have been reported. Recently, we experienced one case of chronic pyelonephritis as a sequela of KHF, which has been diagnosed at the 78th month of illness. This case showed reduced thickness of renal parenchyme, small and irregular shaped kidney, focal loss of normal cupping of calyces, and accumulation of radiacontrast media at distal calyes by IVP. This case suggested that chronic pyelonephritis may develop as a sequela of KHF,

The fundamental physical concepts underlying filamentation are discussed. These include sliceby- slice self-focusing, intensity clamping, back ground reservoir and self-compression of the pulse during propagation.

Studies of group participation in the policymaking process often focus on the activities of groups at discrete points in the policy process such as lobbying Congress (Baumgartner and Leech 2000; Hojnacki and Kimball 2001), or participating in the activities of federal advisory committees (FACs) at the rule-making or policy implementation stage (Balla and Wright 2000; Petracca 1986). The policymaking process, however, encompasses multiple stages in which issues are defined, agendas are set and policies are implemented (see Anderson 1994, 280-287); yet there are no studies that examine group participation throughout all facets of this process. Any normative conclusions regarding the impact of group politics on representative democracy depend on whether or not groups that participate at one stage are also major players in other stages of the policy process. We report findings from a case study of a transportation policy FAC and preliminary analysis of membership in a sample of FACs in health, agriculture and science policy domains in 2000. Interest group participation in FACs does not appear to be biased in favor of business interests.
DISCOVERY OF AN X-RAY-EMITTING CONTACT BINARY SYSTEM 2MASS J11201034−2201340
Hu, Chin-Ping,Yang, Ting-Chang,Chou, Yi,Liu, L.,Qian, S.-B.,Hui, C. Y.,Kong, Albert K. H.,Lin, L. C. C.,Tam, P. H. T.,Li, K. L.,Ngeow, Chow-Choong,Chen, W. P.,Ip, Wing-Huen American Astronomical Society 2016 The Astronomical journal Vol.151 No.6
<P>We report the detection of orbital modulation, a model solution, and the X-ray properties of a newly discovered contact binary, Two Micron All Sky Survey (2MASS) J11201034-2201340. We serendipitously found this X-ray point source outside the error ellipse when searching for possible X-ray counterparts of 7-ray millisecond pulsars among the unidentified objects detected by the Fermi Gamma-ray Space Telescope. The optical counterpart of the X-ray source (unrelated to the 7-ray source) was then identified using archival databases. The long-term Catalina Real-Time Transient Survey detected a precise signal with a period of P = 0.28876208 (56) days. A follow-up observation made by the Super Light Telescope of Lulin Observatory revealed the binary nature of the object. Utilizing archived photometric data of multi-band surveys, we construct the spectral energy distribution (SED), which is well fit by a K2V spectral template. The fitting result of the orbital profile using the Wilson Devinney code suggests that 2MASS J11201034-2201340 is a short-period A-type contact binary and the more massive component has a cool spot. The X-ray emission was first noted in observations made by Swift, and then further confirmed and characterized by an XMM-Newton observation. The X-ray spectrum can be described by a power law or thermal Bremsstrahlung. Unfortunately, we could not observe significant X-ray orbital modulation. Finally, according to the SED, this system is estimated to be 690 pc from Earth with a calculated X-ray intensity of (0.7 - 1.5) x 10(30) erg s(-1), which is in the expected range of an X-ray emitting contact binary.</P>

<P>Enormous advances in genome editing technology have been achieved in recent decades. Among newly born genome editing technologies, CRISPR/Cas9 is considered revolutionary because it is easy to use and highly precise for editing genes in target organisms. CRISPR/Cas9 technology has also been applied for removing unfavorable target genes. In this study, we used CRISPR/Cas9 technology to reduce ethyl carbamate (EC), a potential carcinogen, which was formed during the ethanol fermentation process by yeast. Because the yeast CAR1 gene encoding arginase is the key gene to form ethyl carbamate, we inactivated the yeast CAR1 gene by the complete deletion of the gene or the introduction of a nonsense mutation in the CAR1 locus using CRISPR/Cas9 technology. The engineered yeast strain showed a 98 % decrease in specific activity of arginase while displaying a comparable ethanol fermentation performance. In addition, the CAR1-inactivated mutants showed reduced formation of EC and urea, as compared to the parental yeast strain. Importantly, CRISPR/Cas9 technology enabled generation of a CAR1-inactivated yeast strains without leaving remnants of heterologous genes from a vector, suggesting that the engineered yeast by CRISPR/Cas9 technology might sidestep GMO regulation.</P>
The Closing-in Phenomenon in Alzheimer's Disease and Vascular Dementia

<P><B>Background and Purpose</B></P><P>The closing-in phenomenon is the tendency to draw near or on the target when copying figures, which has been found mostly in patients with Alzheimer's disease (AD). We attempted to quantify the degree of closing-in and to compare it between patients with AD and vascular dementia (VaD).</P><P><B>Methods</B></P><P>The subjects (55 AD, 39 VaD and 38 normal controls) were asked to copy the figure of alternating square and triangle, starting at the designated point and continuing from left to right. The patients with AD and VaD did not differ in age, education, severity of dementia or Rey Complex Figure Test copy score. The proximity (Y-axis) of the subject's drawing to the target was plotted at intervals of 2 mm along the X-axis and the degree of closing-in was computed from the slope of the regression line.</P><P><B>Results</B></P><P>The AD and VaD patients showed a steeper slope than the controls. There was no significant difference, however, in the magnitude of closing-in of the AD and VaD patients. When closing-in was defined as a slope that was greater than the mean+2SD of the slope observed for the controls, 32.7% of the AD and 25.6% of the VaD patients showed closing-in.</P><P><B>Conclusions</B></P><P>Our study, using a new method of measuring the degree of closing-in, suggests that this phenomenon is not specific to AD.</P>

Mixing and dilution are essential procedures in pharmaceutical operation to aliquot two or more components serially to produce less concentrated and well mixed solutions. However, conventional serial dilution method used in laboratory is tedious and utilized large quantity of plasticwares. In this study, a two-tier microdilution device with two inlets and four outlets was designed, simulated, and prototyped to dilute Cytochalasin-B (CB). Using the microdilution device, CB in linear concentration gradients were produced based on one-step dilution method. The different concentrations of CB were applied to treat monolayer and microtissues of ORL-48 cells. The morphological responses, cell viability and cell proliferation of ORL-48 monolayer cells (2D) and microtissues (3D) treated in four different CB concentrations were investigated via phase contrast microscopy, live/dead stainings, and Alamar Blue® assay, respectively. The results showed that 2D ORL-48 cells were morphologically affected but 3D ORL-48 cells stayed viable and proliferative after treated with similar concentrations of CB. The microdilution device enables serial dilutions to produce reagents in linear concentration gradients via a one-step dilution method.
