Effects of 12 Weeks of Continuous Exercise and Accumulation of Short-Duration Exercise on Body Composition, Physical Fitness, and Lifestyle Disease indices in Overweight Men in their 30s
PURPOSE This study aimed to investigate the effects of continuous exercise and the accumulation of short-duration exercise for 12 weeks on body composition, physical fitness, and lifestyle disease indices in overweight men in their 30s. METHODS Participants in the continuous exercise group (CE; n=13) performed a circuit exercise program of 30 min/session, 3 sessions/week for 12 weeks. Participants in the accumulation of short duration exercise group (ASE; n=12) performed the same exercise time of 30 min per day, divided into three sessions of 10 min. Body composition, physical fitness, and lifestyle disease indices were measured pre- and post-test and were compared by utilizing a repeated two-way ANOVA. RESULTS 1) Regarding body composition, body weight, body mass index, skeletal muscle mass, waist circumference, and fat mass decreased significantly, while hip circumference increased significantly in the CE group. Waist circumference and skeletal muscle mass decreased significantly, while hip circumference increased significantly in the ASE group. 2) Regarding physical fitness, right grip strength, sit and reach, sit up, and maximal oxygen uptake increased significantly in both groups. 3) Regarding hypertension indices, there were no significant differences in both groups, but they showed a tendency to improve. 4) Regarding hyperlipidemia indices, triglycerides (TG) decreased significantly in both groups, and total cholesterol (TC) decreased significantly in the CE group. 5) Regarding diabetes indices, there were no significant differences in both groups, but a tendency to improve was noticed. 6) Regarding arteriosclerosis indices: TG/high density lipoprotein-cholesterol ratio decreased significantly in both groups, and the TC/high density lipoprotein-cholesterol ratio decreased significantly in the CE group. CONCLUSIONS We concluded that both the accumulation of short duration exercise and continuous exercise can be effective in improving body composition, physical fitness, and lifestyle disease in overweight men
The Connection between Star-Forming Galaxies, AGN Host Galaxies and Early-Type Galaxies in the SDSS
We present a study of the connection between star-forming galaxies, AGN host
galaxies, and normal early-type galaxies in the Sloan Digital Sky Survey
(SDSS). Using the SDSS DR5 and DR4plus data, we select our early-type galaxy
sample in the color versus color-gradient space, and we classify the spectral
types of the selected early-type galaxies into normal, star-forming, Seyfert,
and LINER classes, using several spectral line flux ratios. We investigate the
slope in the fundamental space for each class of early-type galaxies and find
that there are obvious differences in the slopes of the fundamental planes
(FPs) among the different classes of early-type galaxies, in the sense that the
slopes for Seyferts and star-forming galaxies are flatter than those for normal
galaxies and LINERs. This may be the first identification of the systematic
variation of the FP slope among the subclasses of early-type galaxies. The
difference in the FP slope might be caused by the difference in the degree of
nonhomology among different classes or by the difference of gas contents in
their merging progenitors. One possible scenario is that the AGN host galaxies
and star-forming galaxies are formed by gas-rich merging and that they may
evolve into normal early-type galaxies after finishing their star formation or
AGN activities.Comment: 5 pages with emulateapj, 2 figures, accepted for publication in the

Nuclear starburst activity induced by elongated bulges in spiral galaxies
We study the effects of bulge elongation on the star formation activity in
the centers of spiral galaxies using the data from the Sloan Digital Sky Survey
Data Release 7. We construct a volume-limited sample of face-on spiral galaxies
with 19.5 mag at 0.02 0.055 by excluding barred galaxies,
where the aperture of the SDSS spectroscopic fibre covers the bulges of the
galaxies. We adopt the ellipticity of bulges measured by Simard et al. (2011)
who performed two-dimensional bulge+disc decompositions using the SDSS images
of galaxies, and identify nuclear starbursts using the fibre specific star
formation rates derived from the SDSS spectra. We find a statistically
significant correlation between bulge elongation and nuclear starbursts in the
sense that the fraction of nuclear starbursts increases with bulge elongation.
This correlation is more prominent for fainter and redder galaxies, which
exhibit higher ratios of elongated bulges. We find no significant environmental
dependence of the correlation between bulge elongation and nuclear starbursts.
These results suggest that non-axisymmetric bulges can efficiently feed the gas
into the centre of galaxies to trigger nuclear starburst activity.Comment: 9 pages, 7 figures, accepted for publication in MNRA
Cerebral oximetry monitoring during aortic arch aneurysm replacement surgery in Jehovah's Witness patient -A case report-
Anesthetic management for aortic arch aneurysm (AAA) surgery employing deep hypothermic circulatory arrest in a Jehovah's Witness (JW) patient is a challenge to anesthesiologist due to its complexity of procedures and their refusal of allogeneic transfusion. Even in the strict application of intraoperative acute normovolemic hemodilution (ANH) and intraopertive cell salvage (ICS) technique, prompt timing of re-administration of salvaged blood is essential for successful operation without allogeneic transfusion or ischemic complication of major organs. Cerebral oximetery (rSO2) monitoring using near infrared spectroscopy is a useful modality for detecting cerebral ischemia during the AAA surgery requiring direct interruption of cerebral flow. The present case showed that rSO2 can be used as a trigger facilitating to find a better timing for the re-administration of salvaged blood acquired during the AAA surgery for JW patient
North Ecliptic Pole Wide Field Survey of AKARI: Survey Strategy and Data Characteristics
We present the survey strategy and the data characteristics of the North
Ecliptic Pole (NEP) Wide Survey of AKARI. The survey was carried out for about
one year starting from May 2006 with 9 passbands from 2.5 to 24 micron and the
areal coverage of about 5.8 sq. degrees centered on NEP. The survey depth
reaches to 21.8 AB magnitude near infrared (NIR) bands, and ~ 18.6 AB
maggnitude at the mid infrared (MIR) bands such as 15 and 18 micron. The total
number of sources detected in this survey is about 104,000, with more sources
in NIR than in the MIR. We have cross matched infrared sources with optically
identified sources in CFHT imaging survey which covered about 2 sq. degrees
within NEP-Wide survey region in order to characterize the nature of infrared
sources. The majority of the mid infrared sources at 15 and 18 micron band are
found to be star forming disk galaxies, with smaller fraction of early type
galaxies and AGNs. We found that a large fraction (60~80 %) of bright sources
in 9 and 11 micron stars while stellar fraction decreases toward fainter
sources. We present the histograms of the sources at mid infrared bands at 9,
11, 15 and 18 micron. The number of sources per magnitude thus varies as m^0.6
for longer wavelength sources while shorter wavelength sources show steeper
variation with m, where m is the AB magnitude.Comment: 18 pages, 11 figures, to appear in PASJ, Vol. 61, No. 2. April 25,

Washington CCD Photometry of the Globular Cluster System of the Giant Elliptical Galaxy M60 in Virgo
We present a photometric study of the globular clusters in the giant
elliptical galaxy M60 in the Virgo cluster, based on deep, relatively wide
field Washington CT_1 CCD images. The color-magnitude diagram reveals a
significant population of globular clusters in M60, and a large number of young
luminous clusters in NGC 4647, a small companion spiral galaxy north-west of
M60. The color distribution of the globular clusters in M60 is clearly bimodal,
with a blue peak at (C-T_1)=1.37, and a red peak at (C-T_1)=1.87. We derive two
new transformation relations between the (C-T_1)_0 color and [Fe/H] using the
data for the globular clusters in our Galaxy and M49. Using these relations we
derive the metallicity distribution of the globular clusters in M60, which is
also bimodal: a dominant metal-poor component with center at [Fe/H]=-1.2, and a
weaker metal-rich component with center at [Fe/H]=-0.2. The radial number
density profile of the globular clusters is more extended than that of the
stellar halo, and the radial number density profile of the blue globular
clusters is more extended than that of the red globular clusters. The number
density maps of the globular clusters show that the spatial distribution of the
blue globular clusters is roughly circular, while that of the red globular
cluster is elongated similarly to that of the stellar halo. We estimate the
total number of the globular clusters in M60 to be 3600+/-500$,and the specific
frequency to be S_N=3.8+/-0.4. The mean color of the bright blue globular
clusters gets redder as they get brighter in both the inner and outer region of
M60. This blue tilt is seen also in the outer region of M49, the brightest
Virgo galaxy. Implications of these results are discussed.Comment: 32 pages, 22 figues, Accepted by Ap
Abrupt formation of intracardiac thrombus during cardiopulmonary bypass with full heparinization -A case report-
Intracardiac thrombus during cardiopulmonary bypass (CPB) with full heparinization is very rare but fatal. A 60-year-old woman was scheduled for aortic and mitral valve repairs with a maze procedure for mixed aortic and mitral valvular heart disease with atrial fibrillation. Preoperative transthoracic echocardiography and cardiac computed tomography showed moderate aortic regurgitation and moderate mitral stenosis with regurgitation. There was no intracardiac thrombus. Aortic and mitral valve repairs with the maze procedure were successfully performed without unexpected events. During CPB weaning, a mobile hyper-echogenic mass in the left atrium was detected on transesophageal echocardiography. After cardiac arrest, it was surgically removed. On completion of the operation, weaning from CPB was accomplished uneventfully. The patient fully recovered and was discharged from the intensive care unit on her third postoperative day
The Globular Cluster System of M60 (NGC 4649). I. CFHT MOS Spectroscopy and Database
We present the measurement of radial velocities for globular clusters in M60,
giant elliptical galaxy in the Virgo cluster. Target globular cluster
candidates were selected using the Washington photometry based on the deep
16\arcmin \times 16\arcmin images taken at the KPNO 4m and using the
photometry derived from the HST/WFPC2 archive images. The spectra of the target
objects were obtained using the Multi-Object Spectrograph (MOS) at the
Canada-France-Hawaii Telescope (CFHT). We have measured the radial velocity for
111 objects in the field of M60: 93 globular clusters (72 blue globular
clusters with and 21 red globular clusters with
), 11 foreground stars, 6 small galaxies, and the nucleus of
M60. The measured velocities of the 93 globular clusters range from
km s to km s, with a mean value of
km s, which is in good agreement with the velocity of the nucleus of M60
( km s). Combining our results with data in the
literature, we present a master catalog of radial velocities for 121 globular
clusters in M60. The velocity dispersion of the globular clusters in the master
catalog is found to be km s for the entire sample,
km s for 83 blue globular clusters, and
km s for 38 red globular clusters.Comment: 29 pages, 8 figures. To appear in Ap
