We apply the Tremaine-Weinberg method of pattern speed determination to data cubes of CO emission in six spiral galaxies from the BIMA SONG survey each with an ISM dominated by molecular gas. We compare derived pattern speeds with estimates based on other methods, usually involving the identification of a predicted behavior at one or more resonances of the pattern(s). In two cases (NGC 1068 and...

Background: Relatively little is known about acute exacerbation (AE) of interstitial pneumonia associated with collagen vascular diseases (CVD-IPs). Objectives: This study was aimed at clarifying clinical characteristics and outcome in AE of CVD-IPs, compared with those of idiopathic interstitial pneumonias (IIPs). Methods: We retrospectively reviewed 112 admission cases with suspected AE of CV...

BACKGROUND In many HIV programmes in Africa, patients are assessed clinically and prepared for antiretroviral treatment over a period of 4-12 weeks. Mortality rates following initiation of ART are very high largely because patients present late with advanced disease. The rates of mortality and retention during the pre-treatment period are not well understood. We conducted an observational study...

BACKGROUND Visceral leishmaniasis (VL) is a multifactorial disease, where the host genetics play a significant role in determining the disease outcome. The immunological role of anti-inflammatory cytokine, Interleukin 10 (IL10), has been well-documented in parasite infections and considered as a key regulatory cytokine for VL. Although VL patients in India display high level of IL10 in blood se...

BACKGROUND Off-pump coronary artery bypass surgery has been demonstrated to reduce morbidity in elective patients. However, high-risk patients might benefit the most from this surgical procedure. Our goal was to investigate the effectiveness of on-pump and off-pump coronary artery bypass surgery on early clinical outcome in a consecutive series of overweight patients. METHODS AND RESULTS From...

We study the old problem of the uniqueness of chemical evolution models by analyzing a set of multiphase models for the galaxy NGC 4303 computed for a variety of plausible physical input parameters. We showed in Mollá et al. (1999) that multiphase chemical evolution models for the three Virgo cluster galaxies NGC 4303, NGC 4321 and NGC 4535, were able to reproduce the observed radial distributi...

The CO-to-H$_2$ conversion factor ($\alpha_\rm{CO}$) is central to measuring the amount and properties of molecular gas. It known vary with environmental conditions, previous studies have revealed lower $\alpha_\rm{CO}$ in centers some barred galaxies on kpc scales. To unveil physical drivers such variations, we obtained ALMA Band 3, 6, 7 observations toward inner 2 NGC 3627 4321 tracing $^{12}...

New photometric and spectroscopic observations of galaxies in the directions of three distant clusters are presented as part of our on-going high-redshift cluster survey. The clusters are CL1324+3011 at z = 0.76, CL1604+4304 at z = 0.90, and CL1604+4321 at z = 0.92. We have spectroscopically confirmed cluster membership for 20 to 40 galaxies in each system and have also obtained spectra for ove...
