Delta Opioid Receptors within the Cortico‐Thalamic Circuitry Underlie Hyperactivity Induced by High‐Dose Morphine

open access: yesAdvanced Science, EarlyView.
Morphine activates the excitatory cingulate cortex–intermediate rostrocaudal division of zona incerta (Cg‐ZIm) pathway to drive hyperlocomotion in mice. Inhibiting the Cg‐ZIm pathway attenuates both acute and chronic morphine‐induced hyperlocomotion, while its activation mimics morphine's motor effects.

Jitter Across 15 yr: Leveraging Precise Photometry from Kepler and TESS to Extract Exoplanets from Radial Velocity Time Series

open access: yesThe Astronomical Journal
Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme-precision RV science. Previous work has shown that photometry can be very effective at removing such signals from RV data, especially ...

AS 314: A Massive Dusty Hypergiant or a Low-Mass Post-Asymptotic Giant Branch Object?

open access: yesGalaxies
AS 314 (V452 Sct) is a poorly studied early-type emission-line star, which exhibits an infrared excess at wavelengths longer than 10 μm. Its earlier studies have been limited to small amounts of observational data and led to controversial conclusions ...

Photometric Redshifts and Photometry Errors

open access: yes, 2007
We examine the impact of non-Gaussian photometry errors on photometric redshift performance. We find that they greatly increase the scatter, but this can be mitigated to some extent by incorporating the correct noise model into the photometric redshift ...

Forelimb Motor Learning and Memory Consolidation Drives Distinct Oligodendrocyte Plasticity to Regulate Task‐related Neuronal Activity

open access: yesAdvanced Science, EarlyView.
Genetic and chemical tracking of oligodendrogenesis, combining fiber photometric neuronal activity recording, reveals that distinct oligodendrocyte plasticities are adopted during different phases of motor learning to fine‐tune task‐related neuronal activity, with a preferential involvement of oligodendrogenesis suppression and node lengthening (type 2

New Light Curves and Orbital Period Investigations of the Interacting Binary System UV Piscium

open access: yesJournal of Astronomy and Space Sciences, 2019
UV Psc is a typical RS CVn type system undergoing dynamic chromosphere activity. We performed photometric observations of the system in 2015 and secured new BVR light curves showing well-defined photometric waves.

LncRNA THUMPD3‐AS1 Regulates Behavioral and Synaptic Structural Abnormalities in Schizophrenia via miR‐485‐5p and ARHGAP8

open access: yesAdvanced Science, EarlyView.
Schizophrenia (SCZ) is linked to synaptic structural deficits driven by dysregulated noncoding RNAs. Using the novel ceRNAxis pipeline, THUMPD3‐AS1/miR‐485‐5p/ARHGAP8 is identified as a key regulator of actin cytoskeletal remodeling through noncanonical RhoB/C‐ROCK2 signaling. Modulating this axis ameliorates SCZ‐like phenotypes in mice and aligns with

Photometric Confirmation of MACHO Large Magellanic Cloud Microlensing Events

open access: yes, 2005
We present previously unpublished photometry of three Large Magellanic Cloud (LMC) microlensing events and show that the new photometry confirms the microlensing interpretation of these events.

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...
