We built a 8 $\mu$m selected sample of galaxies in the NEP-AKARI field by defining 4redshift bins with the four AKARI bands at 11, 15, 18 and 24 microns (0.15 < z < 0.49,0.75 < z < 1.34, 1.34 < z < 1.7 and 1.7 < z < 2.05) . Our sample contains 4079 sources, 599 are securely detected with$Herschel$/PACS. Also adding ultraviolet (UV) data from $GALEX$, we fit the spectral energy distributions using the physically motivated codeCIGALE to extract the star formation rate, stellar mass, dustattenuation and the AGN contribution to the total infrared luminosity ($L_{\rm IR}$). We discuss the impact of the adoptedattenuation curve and that of the wavelength coverage to estimate these physical parameters. We focus on galaxies with a luminosity close the characteristic $L_{\rm IR}^*$ in the different redshift bins to studythe evolution with redshift of the dust attenuation in these galaxies.

The recent updates of the North Ecliptic Pole deep (0.5~deg$^2$, NEP-Deep)multi-wavelength survey covering from X-ray to radio-wave is presented. The NEP-Deep provides us with several thousands of 15~$\mu$m or 18~$\mu$mselected galaxies, which is the largest sample ever made at thesewavelengths. A continuous filter coverage in the mid-infrared wavelength(7, 9, 11, 15, 18, and 24~$\mu$m) is unique and vital to diagnose thecontributions from starbursts and AGNs in the galaxies out to $z$=2. The new goal of the project is to resolve the nature of the cosmic star formationhistory at the violent epoch (e.g. $z$=1--2), and to find a clue to understandits decline from $z$=1 to presentuniverse by utilizing the unique power of the multiwavelength survey. The progressin this context is briefly mentioned.

<P>Purpose: To evaluate transarterial chemoembolization (TACE) use prior to and concomitantly with sorafenib in patients with unresectable hepatocellular carcinoma (HCC) across different global regions. Materials and Methods: GIDEON is an observational registry study of more than 3000 HCC patients. Patients with histologically, cytologically, or radiographically diagnosed HCC, and for whom a decision had been made to treat with sorafenib, were eligible. Patients were enrolled into the registry from 39 countries beginning in January 2009, with the last patient follow-up in April 2012. Detailed data on treatment history, treatment patterns, adverse events, and outcomes were collected. All treatment decisions were at the discretion of the treating physicians. Documented approval from local ethics committees was obtained, and all patients provided signed informed consent. Descriptive statistics, including minimum, median, and maximum, were calculated for metric data, and frequency tables for categorical data. Kaplan-Meier estimates with 95% confidence intervals were calculated for survival end points. Results: A total of 3202 patients were eligible for safety analysis, of whom 2631 (82.2%) were male. Median age was 62 years (range, 15-98 years). A total of 1511 (47.2%) patients underwent TACE prior to sorafenib; 325 (10.1%) underwent TACE concomitantly. TACE prior to sorafenib was more common in Japan and Asia- Pacific compared with all other regions (362 [71.3%] and 560 [60.3%] vs 12-209 [13.3%-37.1%]). Adverse events were reported in 2732 (85.3%) patients overall, with no notable differences in the incidence of adverse events, regardless of TACE treatment history. Overall survival was 12.7 months in prior-TACE patients, 9.2 months in non-prior-TACE patients, 21.6 months in concomitant-TACE patients, and 9.7 months in non-concomitant-TACE patients. Conclusion: Global variation exists in TACE use in sorafenib-treated HCC patients. The combination of TACE with sorafenib appears to be a well-tolerated and viable therapeutic approach.

<P>Abstract. Equatorial Kelvin and mixed Rossby-gravity (MRG) waves in the tropical tropopause layer and stratosphere represented in recent reanalyses for the period of 1981-2010 are compared in terms of spectral characteristics, spatial structures, long-term variations, and their forcing of the quasi-biennial oscillation (QBO). For both wave types, the spectral distributions are broadly similar among most of the reanalyses, while the peak amplitudes exhibit considerable spread. The longitudinal distributions and spatial patterns of wave perturbations show reasonable agreement between the reanalyses. A few exceptions to the similarity of the spectral shapes and spatial structures among them are also noted. While the interannual variations of wave activity appear to be coherent for both the Kelvin and MRG waves, there is substantial variability in long-term trends among the reanalyses. Most of the reanalyses which assimilate satellite data exhibit large increasing trends in wave variance (∼15 %-50 % increase in 30 years at 100-10 hPa), whereas one reanalysis (Japanese 55-year Reanalysis assimilating conventional observations only; JRA-55C) produced without satellite data does not. Several discontinuities are found around 1998 in the time series of the Kelvin and MRG wave variances, which manifest in different ways depending on the reanalysis, and are indicative of impacts of the transition of satellite measurements during that year. The equatorial wave forcing of the QBO, estimated by the Eliassen-Palm (EP) flux divergence, occurs in similar phase-speed ranges in the lower stratosphere among the reanalyses. However, the EP flux and its divergence are found to be dependent on the zonal-mean winds represented in reanalyses, exhibiting different magnitudes, altitudes, and phase-speed ranges of the Kelvin wave forcing between the reanalyses, especially at 20-10 hPa. In addition, at around 20 hPa, a wave signal which appears only in easterly mean winds with westward phase speeds is found and discussed. </P>

Cerebral small vessel disease (cSVD) has a crucial role in lacunar stroke and brain hemorrhages and is a leading cause of cognitive decline and functional loss in elderly patients. Based on underlying pathophysiology, cSVD can be subdivided into amyloidal and non-amyloidal subtypes. Genetic factors of cSVD play a pivotal role in terms of unraveling molecular mechanism. An important pathophysiological mechanism of cSVD is blood-brain barrier leakage and endothelium dysfunction which gives a clue in identification of the disease through circulating biological markers. Detection of cSVD is routinely carried out by key neuroimaging markers including white matter hyperintensities, lacunes, small subcortical infarcts, perivascular spaces, cerebral microbleeds, and brain atrophy. Application of neural networking, machine learning and deep learning in image processing have increased significantly for correct severity of cSVD. A linkage between cSVD and other neurological disorder, such as Alzheimer’s and Parkinson’s disease and non-cerebral disease, has also been investigated recently. This review draws a broad picture of cSVD, aiming to inculcate new insights into its pathogenesis and biomarkers. It also focuses on the role of deep machine strategies and other dimensions of cSVD by linking it with several cerebral and non-cerebral diseases as well as recent advances in the field to achieve sensitive detection, effective prevention and disease management.
