The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) is the first interferometer dedicated to studying the cosmic microwave background (CMB) radiation at 3mm wavelength. The choice of 3 mm was made to minimize the contributions from foreground synchrotron radiation and Galactic dust emission. The initial configuration of seven 0.6 m telescopes mounted on a 6-m hexapod platform was dedicated in October 2006 on Mauna Loa, Hawaii. Scientific operations began with the detection of a number of clusters of galaxies via the thermal Sunyaev-Zel'dovich effect. We compare our data with Subaru weak lensing data in order to study the structure of dark matter. We also compare our data with X-ray data in order to derive the Hubble constant.
Our results showed that administration of DHEA during allergic sensitization could attenuate the subsequent allergic responses elicited by challenge, and that the suppressive effect of DHEA was associated with a down-regulation of TH2 response.
We developed a forced non-electric-shock running wheel (FNESRW) system that provides
rats with high-intensity exercise training using automatic exercise training patterns
that are controlled by a microcontroller. The proposed system successfully makes a
breakthrough in the traditional motorized running wheel to allow rats to perform
high-intensity training and to enable comparisons with the treadmill at the same
exercise intensity without any electric shock. A polyvinyl chloride runway with a
rough rubber surface was coated on the periphery of the wheel so as to permit
automatic acceleration training, and which allowed the rats to run consistently at
high speeds (30 m/min for 1 h). An animal ischemic stroke model was used to validate
the proposed system. FNESRW, treadmill, control, and sham groups were studied. The
FNESRW and treadmill groups underwent 3 weeks of endurance running training. After 3
weeks, the experiments of middle cerebral artery occlusion, the modified neurological
severity score (mNSS), an inclined plane test, and triphenyltetrazolium chloride were
performed to evaluate the effectiveness of the proposed platform. The proposed
platform showed that enhancement of motor function, mNSS, and infarct volumes was
significantly stronger in the FNESRW group than the control group (P<0.05) and
similar to the treadmill group. The experimental data demonstrated that the proposed
platform can be applied to test the benefit of exercise-preconditioning-induced
neuroprotection using the animal stroke model. Additional advantages of the FNESRW
system include stand-alone capability, independence of subjective human adjustment,
and ease of use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
