The ensemble of chemical element abundance measurements for stars, along with precision distances and orbit properties, provides high-dimensional data to study the evolution Milky Way. With this third release Galactic Archaeology HERMES (GALAH) survey, we publish 678 423 spectra 588 571 mostly nearby stars (81.2% are within <2 kpc), observed spectrograph at Anglo-Australian Telescope. This (hereafter GALAH+ DR3) includes all observations from GALAH Phase 1 (bright, main, faint 70%),...
PURPOSE To provide expert guidance to clinicians and policymakers in resource-constrained settings on the management of patients with late-stage colorectal cancer. METHODS ASCO convened a multidisciplinary, multinational Expert Panel that reviewed existing guidelines, conducted modified ADAPTE process, used formal consensus process additional experts for two rounds ratings. RESULTS Existing sets guidelines from four guideline developers were identified reviewed; adapted recommendations five...

Abstract Chemical characterization of the Galactic center is essential for understanding its formation and structural evolution. Trends alpha ( α ) elements, such as magnesium, silicon, calcium, serve powerful diagnostic tools, offering insights into star rates gas-infall history. However, high extinction has previously hindered studies. In this study, we present a detailed chemical abundance analysis M giants in Milky Way's nuclear cluster (NSC), focusing on -element trends with...
Baade's window (BW) is one of the most observed Galactic bulge fields in terms chemical abundances. Due to its low and homogeneous interstellar absorption it considered as a calibration field for studies. In era large spectroscopic surveys, such BW are necessary cross calibrate stellar parameters individual abundances APOGEE survey. We use stars derive their metallicity distribution function (MDF) abundances, $\alpha$- iron-peak elements ASPCAP pipeline (DR13), well age BW. determine MDF...
Abstract We report the first high-resolution, detailed abundances of 21 elements for giants in Galactic bulge/bar within 1° plane, where high extinction has rendered such studies challenging. Our high-signal-to-noise-ratio and near-infrared spectra seven M inner bulge, located at ( l , b ) = (0°, +1°), are observed using IGRINS spectrograph. multichemical study bulge by investigating, relative to a robust new solar neighborhood sample, abundance trends elements, including relatively...
Cutaneous leishmaniasis (CL), a neglected tropical disease, is reported to be prevalent in tribal villages located the Agasthyamala Biosphere Reserve forests of Western Ghats, Kerala state, India. We carried out an investigation characterize species Leishmania parasites involved these infections among one oldest human populations Skin aspirates collected from 13 clinically diagnosed cases were subjected histopathological investigations, serological rapid tests using 'rk39' and molecular...
The nuclear stellar disc (NSD) is, together with the star cluster (NSC) and central massive black hole, one of main components in parts our Milky Way. However, until recently, only few studies content NSD have been obtained due to extreme extinction crowding. With a dedicated KMOS (VLT, ESO) spectroscopic survey, we study kinematics global metallicities based on observations K/M giant stars. We trace radial velocities which were derived spectral indices (Na I CO) along compare those Galactic...
Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided (EUS-GBS) have been proposed as safe effective modalities drainage.Data from patients with cholecystitis were prospectively collected August 2004 to May 2013 two United States academic university hospitals analyzed retrospectively. The following algorithm was adopted. retrograde...
Introduction: White Spot Lesions (WSL) are a common problem in orthodontic treatment due to improper oral hygiene maintenance and plaque accumulation, which reduce the bond strength of appliance. To address this issue, various bonding materials have been introduced over time enhance adhesives. Recently, different kinds nanoparticles added composite resins with goal enhancing efficiency without affecting strength. Aim: evaluate shear Titanium Dioxide (TiO2 ) nanoparticle-incorporated...
Abstract An important step in understanding the formation and evolution of nuclear star cluster (NSC) is to investigate its chemistry chemical evolution. Additionally, exploring NSC’s relationship other structures Galactic center Milky Way disks great interest. Extreme optical extinction has previously prevented studies, but near-IR high-resolution spectroscopy now possible. Here, we present a detailed abundance analysis 19 elements—more than 4 times as many published—for nine stars NSC Way,...

Although there have been numerous studies of chemical abundances in the Galactic bulge, central two degrees relatively unexplored due to heavy and variable interstellar extinction, extreme stellar crowding, presence complex foreground disk populations. In this paper we discuss metallicity distribution function, vertical radial gradients $\alpha$-elements inner Milky Way, as obtained by recent IR spectroscopic surveys. We use a compilation measurements metallicities $\alpha$-element derived...
ABSTRACT APOGEE and GALAH are two high resolution multi-object spectroscopic surveys that provide fundamental stellar parameters multiple elemental abundance estimates for about half a million stars in the Milky Way. Both observe different wavelength regimes use data reduction pipelines leading to significant offsets trends abundances common observed both surveys. Such systematic differences/offsets make it difficult effectively utilize them investigate Galactic spite of unique advantage...
Cool stars, such as M giants, can only be analysed in the near-infrared (NIR) regime due to ubiquitous TiO features optical spectra of stars with Teff < 4000 K. In dust obscured regions, like inner bulge and Galactic Center, intrinsically bright giants observed NIR is an optimal option determine their stellar abundances. Due uncertainties photometric methods, a method parameters for from themselves needed. We have carried out new observations 44 giant (also APOGEE DR17) IGRINS (R=45,000)...
