ABSTRACT Background and Aims Obesity is a growing public health concern and major risk factor for conditions including non‐alcoholic fatty liver disease (NAFLD), cardiovascular disease, and diabetes. This study aimed to assess the early effects of one anastomosis gastric bypass (OAGB) surgery on metabolic risk factors and liver‐related parameters in ...

ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

AGB and post-AGB stars at high angular resolution [PDF]
High angular resolution observations have provided some valuable information on the circumstellar environment of AGB and post-AGB stars.We review the recent results obtained in this field and focus on observations showing evidence of non-sphericity at different spatial scales (envelope, jets, binarity, maser clumps, stellar “photosphere”, hot spots ...

ISO observations of AGB and post AGB stars
We review some of the highlights of the ISO observing programmes dedicated to the photospheres and winds of late-type stars. The ISO mission has provided for the first time an unbiased view of the gas-phase molecular components in the extended atmospheres of cool stars.

Abundance analysis of post-AGB stars
Using BD+46 442 as an example, we describe our analysis of the spectra of post-AGB stars (SpTs F-K, luminosity types I-II, [Fe/H]=−2.0...+0.5), obtained with the echelle spectrograph HERMES on the 1.2 m Mercator telescope. We obtain atmospheric parameters and atomic abundances using hydrogen line profiles and equivalent widths (EW) of weak metal lines.

Post-AGB stars in the AKARI survey
Obscured by their circumstellar dusty envelopes post-AGB stars emit a large fraction of their energy in the infrared and thus, infrared sky surveys like IRAS were essential for discoveries of post-AGBs in the past. Now, with the AKARI infrared sky survey we can extend our knowledge about the late stages of stellar evolution.

Evolution and Pulsations of Population I Post-AGB Stars [PDF]
Evolutionary calculations of population I stars with initial masses $M_0=1M_\odot$, $1.5M_\odot$ and $2M_\odot$ were carried out up to the stage of the proto--planetary nebula. Selected models of post--AGB evolutionary sequences with effective temperatures $3.6\times 10^3\,\mathrm{K}\lesssim T_\mathrm{eff}\lesssim 2\times 10^4\,\mathrm{K}$ were used as

Post-AGB Stars with Circumbinary Discs
Circumbinary discs are commonly observed around post-asymptotic giant branch (AGB) systems and are known to play an important role in their evolution. Several studies have pointed out that a circumbinary disc interacts through resonances with the central binary and leads to angular momentum transfer from the central binary orbit to the disc.
