Early Improvements in Metabolic Risk Factors and Non‐Alcoholic Fatty Liver Disease Following One Anastomosis Gastric Bypass Surgery: A 4‐Month Prospective Study

open access: yesHealth Science Reports, Volume 9, Issue 8, August 2026.
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 ...

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

open access: yesAustralian Endodontic Journal, Volume 52, Issue 2, Page 585-605, August 2026.
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]

open access: yesSymposium - International Astronomical Union, 1999
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

open access: yes, 1999
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

open access: yesJournal of Physics: Conference Series, 2011
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

open access: yes, 2009
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]

open access: yesAstronomy Letters, 2019
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

open access: yes, 2012
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.
