Journal of Gastroenterology and Hepatology, EarlyView.ABSTRACT Ulcerative colitis (UC) and Crohn's disease (CD) are increasingly prevalent in the Asia Pacific region, necessitating updated, region‐specific guidance on advanced therapies. Targeted small molecule agents, such as filgotinib, tofacitinib, upadacitinib, etrasimod, and ozanimod; and the IL‐23 p19 inhibitors (guselkumab, mirikizumab ...

Search for quasar pairs with Gaia astrometric data
Astronomy & AstrophysicsQuasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction and clustering, the coevolution between the two quasars’ host galaxies, and the growth of supermassive black holes, as well as the formation and ...

Quasars and their host galaxies
, 2006 This review attempts to describe developments in the fields of quasar and quasar host galaxies in the past five. In this time period, the Sloan and 2dF quasar surveys have added several tens of thousands of quasars, with Sloan quasars being found to z>6.

Microlensing variability in the gravitationally lensed quasar Q2237+0305 = the Einstein Cross, I. Spectrophotometric monitoring with the VLT [PDF]
, 2008 We present the results of the first long-term (2.2 years) spectroscopic monitoring of a gravitationally lensed quasar, namely the Einstein Cross Q2237+0305.

Skepticism and Ontological Parsimony
Pacific Philosophical Quarterly, EarlyView.ABSTRACT External world skepticism is often thought to entail that we should suspend judgment about the existence of the external world. I challenge this orthodoxy by arguing that, when combined with a plausible principle of ontological parsimony, the skeptical challenge intensifies into an argument for outright disbelief in the external world.

Symposium - International Astronomical Union, 1994 I review recent results for quasars and discuss how they are related to activity in galaxies. Topics included are studies of quasar host galaxies with HST; searches for quasars in the Hubble Deep Field; evolution of the quasar luminosity function; news highlights from astro-ph; and current observational research problems and their relation to ...

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.This study examined the association between attention‐deficit/hyperactivity disorder (ADHD) traits and gray matter volume (GMV) in 534 healthy young adults. Higher Hyperactivity/Restlessness scores were associated with greater GMV in the right dorsolateral prefrontal cortex (DLPFC), a region implicated in executive control and behavioral regulation. No

The Astrophysical Journal, 2023 Massive galaxies formed most actively at redshifts z = 1–3 during the period known as “cosmic noon.” Here we present an emission-line study of the extremely red quasar SDSSJ165202.64+172852.3’s host galaxy at z = 2.94, based on observations with the Near

Binary Quasars in the Sloan Digital Sky Survey: Evidence for Excess Clustering on Small Scales
, 2005 We present a sample of 218 new quasar pairs with proper transverse separations R_prop < 1 Mpc/h over the redshift range 0.5 < z < 3.0, discovered from an extensive follow up campaign to find companions around the Sloan Digital Sky Survey and 2dF Quasar ...

ChemMedChem, Volume 21, Issue 9, 14 May 2026.The anticancer activity of the complexes Pd3Spd2, Pt3Spd2, Pt2Put2(NH3)4 and Pd2Put2 against human TNBC, non‐TNBC and healthy breast cells was evaluated. The metabolic impact of the most promising metal complexes—Pd3Spd2 and Pt2Put2(NH3)4—was further assessed using vibrational microspectroscopies, providing detailed insights into the drug‐induced ...
