We establish a robust statistical description of the star-forming galaxy population at the end of cosmic HI reionization ($5.0\le{}z\le6.6$) from a large sample of 52 galaxies with spectroscopically confirmed redshifts from the VIMOS UltraDeep Survey. We identify galaxies with Ly$��$ either in absorption or in emission, at variance with most spectroscopic samples in the literature where Ly$��$ emitters dominate. We find that star-forming galaxies at these redshifts are distributed along a main sequence in the stellar mass vs. SFR plane. We report a flat evolution of the sSFR(z) in 32. The bright end of the Ly$��$ luminosity function has a high number density, indicating a significant star formation activity concentrated in the brightest Ly$��$ emitters (LAE) at these redshifts. LAE with EW>25��~contribute to about 75\% of the total UV-derived SFRD. While our analysis favors a low dust content in 5.0, 27 pages, submitted to A&A

Cushing's syndrome is a state of cortisol excess, possibly from a tumor in the pituitary gland, the adrenal gland, or an ectopic nonpituitary ACTH-secreting source. The first form, pituitary in origin, was originally described by Harvey Cushing, MD, and was labeled as Cushing's disease. Long-term therapy with glucocorticoids also can lead to iatrogenic Cushing's syndrome.

We obtained optical/near-IR rest-frame Magellan FIRE spectra (including Pa$��$ and Pa$��$) of 25 starburst galaxies at 0.5, ApJ Letters in press; the key result is in Figure 4 (left)

Deep observations are revealing a growing number of young galaxies in the first billion year of cosmic time. Compared to typical galaxies at later times, they show more extreme emission-line properties, higher star formation rates, lower masses, and smaller sizes. However, their faintness precludes studies of their chemical abundances and ionization conditions, strongly limiting our understanding of the physics driving early galaxy build-up and metal enrichment. Here we study a rare population of UV-selected, sub$-L^{*}$(z=3) galaxies at redshift 2.4$, Comment: 25 pages, 8 figs, 2 tables. Accepted for publication

Objective. To determine the effect of laparoscopic adjustable gastric banding (LAGB) on weight loss and the association between initial body mass index (BMI) and successful weight loss, defined as >50% excess weight loss (EWL) among obese Filipino adults at St. Luke’s Medical Center. Methodology. Data from 97 patients who were at least 18 years old at the time of gastric banding were reviewed retrospectively. Patient follow-up was poor 2 years post-surgery, which precluded analysis of follow-up data beyond 2 years. Changes in weight loss parameters from baseline to the different observation periods were carried out using paired t- test. To determine the association of different factors with success in weight loss, Independent t-test and Chi-square tests were used. A p-value ≤0.05 was considered significant. Results. Majority of the patients were female (61%) and Southeast Asian (77%). Ages ranged from 18 to 68 years. Mean BMI was 44.1 ± 0.1 kg/m 2 and mean excess weight was 61.4 ± 26.5 kg. Excess weight loss of 43.84 ± 25.09% and BMI reduction of 21.54 ± 13.39% were attained at 2 years. Lower initial BMI with a mean of 38.12±3.28 kg/m 2 was associated with successful weight loss, 1 year after gastric banding (p

We investigate the burstiness of star formation histories (SFHs) of galaxies at $0.4, 13 pages, 8 figures. ApJ accepted. The main conclusions are not changed. Major modifications include: (1) to be consistent with the literature, now reporting H\beta--to--FUV ratio (rather than FUV--to--H\beta\ in the first version); (2) detailed discussions on dust extinction correction; (3) new SF bustiness calculation; and (4) enriched discussions in Introduction

(Abridged) The properties of stellar clumps in star forming galaxies and their evolution over the redshift range $2\lesssim z \lesssim 6$ are presented and discussed in the context of the build-up of massive galaxies at early cosmic times. We use HST/ACS images of galaxies with spectroscopic redshifts from the VIMOS Ultra Deep Survey (VUDS) to identify clumps within a 20 kpc radius. We find that the population of galaxies with more than one clump is dominated by galaxies with two clumps, representing $\sim21-25$\% of the population, while the fraction of galaxies with 3, or 4 and more, clumps is 8-11 and 7-9\%, respectively. The fraction of clumpy galaxies is in the range $\sim35-55\%$ over $2, 17 pages, 11 figures, A&A (in press)

We measure galaxy sizes on a sample of $\sim1200$ galaxies with confirmed spectroscopic redshifts $2 \leq z_{spec} \leq 4.5$ in the VIMOS Ultra Deep Survey (VUDS), representative of star-forming galaxies with $i_\mathrm{AB} \leq 25$. We first derive galaxy sizes applying a classical parametric profile fitting method using GALFIT. We then measure the total pixel area covered by a galaxy above a given surface brightness threshold, which overcomes the difficulty of measuring sizes of galaxies with irregular shapes. We then compare the results obtained for the equivalent circularized radius enclosing 100\% of the measured galaxy light $r_T^{100}$ to those obtained with the effective radius $r_{e,\mathrm{circ}}$ measured with GALFIT. We find that the sizes of galaxies computed with our non-parametric approach span a large range but remain roughly constant on average with a median value $r_T^{100}\sim2.2$ kpc for galaxies with $2, 22 pages, 20 figures (+3 in appendix), submitted to A&A

Advances in the medical management of secondary hyperparathyroidism due to renal failure have decreased the use of parathyroidectomy as a treatment option. However, some patients with end-stage renal disease still progress to refractory hyperparathyroidism and debilitating bone disease, for which parathyroidectomy may be warranted. We describe a case of a 35-year-old female on chronic hemodialysis who presented with bone pains, deformities, decrease in height and recurrent pathologic fractures. She had markedly elevated parathyroid hormone (PTH), vitamin D deficiency, persistent hyperphosphatemia and hypocalcemia despite therapeutic measures. Subtotal parathyroidectomy was done with eventual improvement of biochemical abnormalities, resolution of bone pains and healing of fractures.

The aim of this paper is to investigate spectral and photometric properties of 854 faint ($i_{AB}$$0��), and Ly$��$ emitters (LAEs; EW$\ge$20��). The fraction of LAEs at these redshifts is $\sim$10%, which is consistent with previous observations. We compared best-fit SED-estimated stellar parameters of the SFG$_{\rm N}$, SFG$_{\rm L}$ and LAE samples. For the luminosities probed here ($\sim$L$^*$), we find that galaxies with and without Ly$��$ in emission have small but significant differences in their SED-based properties. We find that LAEs have less dust, and lower star-formation rates (SFR) compared to non-LAEs. We also find that LAEs are less massive compared to non-LAEs, though the difference is smaller and less significant compared to the SFR and E$_{\rm s}$(B-V).

We study the stellar population properties of the IRAC-detected $6 \lesssim z \lesssim 10$ galaxy candidates from the Spitzer UltRa Faint SUrvey Program (SURFS UP). Using the Lyman Break selection technique, we find a total of 16 new galaxy candidates at $6 \lesssim z \lesssim 10$ with $S/N \geq 3$ in at least one of the IRAC $3.6��$m and $4.5��$m bands. According to the best mass models available for the surveyed galaxy clusters, these IRAC-detected galaxy candidates are magnified by factors of $\sim 1.2$--$5.5$. We find that the IRAC-detected $6 \lesssim z \lesssim 10$ sample is likely not a homogeneous galaxy population: some are relatively massive (stellar mass as high as $4 \times 10^9\,M_{\odot}$) and evolved (age $\lesssim 500$ Myr) galaxies, while others are less massive ($M_{\text{stellar}}\sim 10^8\,M_{\odot}$) and very young ($\sim 10$ Myr) galaxies with strong nebular emission lines that boost their rest-frame optical fluxes. We identify two Ly$��$ emitters in our sample from the Keck DEIMOS spectra, one at $z_{\text{Ly}��}=6.76$ (in RXJ1347) and one at $z_{\text{Ly}��}=6.32$ (in MACS0454). We show that IRAC $[3.6]-[4.5]$ color, when combined with photometric redshift, can be used to identify galaxies likely with strong nebular emission lines within certain redshift windows., ApJ in press
