A Freeform Forward-modeling Pipeline for High-contrast Images of Circumstellar Disks Based on Automatic Differentiation

The Astronomical Journal
Modeling circumstellar disks in the traditional sense carries the assumption that the dust density distribution can be accurately described with a fixed parametric form.

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

GALACTICNUCLEUS: A high-angular-resolution JHKs imaging survey of the Galactic center

Astronomy & Astrophysics
Context. The center of the Milky Way presents a unique environment of fundamental astrophysical interest. However, its extreme crowding and extinction make this region particularly challenging to study.

Optical photometry of Sco X-2

Astronomy & Astrophysics, 1997
We present optical photometry of the galactic bulge low-mass X-ray binary GX 349+2 (Sco X-2) obtained in July 1993 and March 1996. Short-term variations up to one magnitude are present on time scales of a few hours, which are related to the known X-ray behaviour of the source.

An Olfactory Piriform Cortex‐Lateral Hypothalamus Neural Circuit Contributes to Linalool‐Induced Analgesia

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Linalool odor exposure activates a glutamatergic projection from the piriform cortex to the lateral hypothalamus (PiriGlu‐LH), mediating descending inhibitory pain pathways. This demonstrates a novel neural mechanism for olfactory‐induced pain modulation and suggests potential therapeutic implications for pain management.

Cleaning Efficacy of Air Polishing on Tobacco‐Stained Resin Composite: An In‐Vitro Study

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objective To evaluate the efficacy of air‐polishing on color change and surface roughness of resin composite and enamel specimens after standardized cigarette smoke exposure. Methods Sixty composite/enamel specimens were exposed daily to cigarette smoke in an automated chamber over four 14‐day cycles (five cigarettes/day).

Levetiracetam inhibits the Na+ HCO3− transporter Ncbe/NBCn2 (Slc4a10) in the choroid plexus of mice

Acta Physiologica, Volume 242, Issue 8, August 2026.
ABSTRACT Aim The Na+‐dependent Cl−/HCO3− exchanger Ncbe/NBCn2 (Slc4a10) constitutes a major basolateral HCO3− uptake pathway in the choroid plexus and contributes to cerebrospinal fluid secretion and pH regulation. This study examined whether levetiracetam inhibits Ncbe/NBCn2‐mediated transport and alters cerebrospinal fluid acid–base balance ...
