A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions tens milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up ~15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from September late November 2014, culminating in end-to-end observations, calibrations, imaging selected Science Verification (SV) targets. This paper presents an overview campaign its main results,...
Genotype-specific incompatibility in legume-rhizobium symbiosis has been suggested to be controlled by effector-triggered immunity underlying pathogenic host-bacteria interactions. However, the rhizobial determinant interacting with host resistance protein (e.g., Rj2) and molecular mechanism of symbiotic remain unclear. Using natural mutants Bradyrhizobium diazoefficiens USDA 122, we identified a type III-secretory NopP as Rj2-soybean. The analysis nopP mutations variants culture collection...
ABSTRACT Background Possible associations of chronic kidney disease (CKD) with fatty liver (FL) and nonalcoholic (NAFLD) have recently been focused on. Metabolic dysfunction–associated (MAFLD), defined as FL overweight/obesity, type 2 diabetes mellitus or metabolic abnormalities, has proposed a new feature disease. However, the relationship between MAFLD onset CKD not fully addressed. Methods We investigated FL, NAFLD development CKD, an estimated glomerular filtration rate (eGFR) <60...
We present a high angular resolution map of 850 um continuum emission the Orion Molecular Cloud-3 (OMC 3) obtained with Submillimeter Array (SMA); is mosaic 85 pointings covering an approximate area 6'.5 x 2'.0 (0.88 0.27 pc). detect 12 spatially resolved sources, each H_2 mass between 0.3-5.7 Mo and projected source size 1400-8200 AU. All detected sources are on filamentary main ridge n_H2>10^6 cm^-3), analysis based Jeans theorem suggests that they most likely gravitationally unstable....
Abstract Most protostars have luminosities that are fainter than expected from steady accretion over the protostellar lifetime. The solution to this problem may lie in episodic mass accretion—prolonged periods of very low punctuated by short bursts rapid accretion. However, timescale and amplitude for variability at phase is almost entirely unconstrained. In A James Clerk Maxwell Telescope/SCUBA-2 Transient Survey Protostars Nearby Star-forming Regions, we monitoring monthly with SCUBA-2...
We present sensitive, high angular resolution ($\sim$ 0.2 arcsec) submillimeter continuum and line observations of IRAS 16293-2422B made with the Atacama Large Millimeter/Submillimeter Array (ALMA). The 0.45 mm reveal a single very compact source associated 16293-2422B. This has deconvolved size about 400 {\it milli-arcseconds} (50 AU), does not show any inner structure inside this diameter. H$^{13}$CN, HC$^{15}$N, CH$_{3}$OH emission regions are twice as large pronounced depression or...

Abstract We analyze results from the first 18 months of monthly submillimeter monitoring eight star-forming regions in JCMT Transient Survey. In our search for stochastic variability 1643 bright peaks, only previously identified source, EC 53, shows behavior well above expected measurement uncertainty. Another four sources—two disks and two protostars—show moderately enhanced standard deviations brightness, as variables. For protostars, this apparent is result single epochs that are much...
Fatty liver index (FLI) calculated by using body mass (BMI), waist circumference and levels of γ-glutamyl transferase triglycerides is a non-invasive predictor nonalcoholic fatty disease (NAFLD). The original study in Italy showed that the cutoff level for prediction NAFLD was FLI ≥60. However, sex difference not taken into consideration, it unclear whether value can be applied to other races. We investigated determined abdominal ultrasonography receiver operating characteristic curve...

Heat stress inhibits ovarian follicular development in mammalian species. We hypothesized that heat the function of granulosa cells and suppresses development. To test this, immature female rats were injected with pregnant mare serum gonadotropin (PMSG) at 48 h after start temperature treatment (control: 25 degrees C, 50% RH; stress: 35 70% Relative Humidity). The ovaries follicles different developmental stages analyzed for receptor levels aromatase activity; estradiol measured fluid....

We investigated the relationship index (FLI), a noninvasive simple predictor of NAFLD, development CKD defined as estimated glomerular filtration rate < 60 mL/min/1.73 m 2 or positive for urinary protein during 10-year follow-up period in subjects who received annual health examinations (n = 28,890). After exclusion at baseline, total 14,163 (male/female: 9077/5086)...
Background Fatty liver index (FLI), a predictor of nonalcoholic fatty disease, has been reported to be associated with several metabolic disorders. Because sex difference in FLI level, we hypothesized that is development hypertension greater extent men or women. Methods and Results We investigated the relationship between during 10-year period general population subjects who received annual health examinations (n=28 990).

Using the ASTE 10 m submillimeter telescope and 1.4 Infrared Survey Facility (IRSF), we performed an extensive outflow survey in Orion Molecular Cloud 2 3 region. Our survey, which includes 41 potential star-forming sites, has been newly compiled using multiwavelength data based on millimeter- submillimeter-continuum observations, as well radio continuum observations. From CO(3-2) observations with Atacama Submillimeter Telescope Experiment (ASTE) telescope, detected 14 CO molecular...
We present subarcsecond resolution HCN (4–3) and CO (3–2) observations made with the Submillimeter Array, toward an extremely young intermediate-mass protostellar core, MMS 6-main, located in Orion Molecular Cloud 3 region (OMC-3). have successfully imaged a compact molecular outflow lobe (≈1000 AU) associated which is also smallest ever found cores.

Both high- and low-velocity outflows are occasionally observed around a protostar by molecular line emission. The high-velocity component is called `Extremely High-Velocity (EHV) flow,' while the simply referred as `(molecular) outflow.' This study reports newly found EHV flow outflow MMS $5$ in Orion Molecular Cloud 3 with ALMA. In observation, CO $J$=2--1 emission traces both ($|v_{\rm{LSR}} - v_{\rm{sys}}|$ $\simeq$ 50--100 $\rm{km\ s^{-1}}$) 10--50 s^{-1}}$). On other hand, SiO $J$=5--4...
