Estrogen Alleviates Sevoflurane‐Induced Neurotoxicity by Inhibiting ERα‐Tau Binding

Advanced Science, EarlyView.
Sevoflurane‐induced neurotoxicity exhibits sex differences, and estrogen can mitigate these effects; however, its protective action appears to be time‐window dependent, which may be related to the competitive binding of estrogen and Tau to ERα. Abstract Sevoflurane‐induced neurotoxicity is age‐dependent, but the role of sex differences is unclear ...

TRIPP: An Aperture Photometry Package for the Reduction of CCD Time Series Images

Open Astronomy, 2003
TRIPP is an aperture photometry program designed with the purpose of extracting light curves from large sets of similar CCD frames typically obtained during time-resolved photometric monitoring campaigns such as, for example, WET runs.

Photocatalytic Activity of Ionic Carbon Nitrides is Governed by Cation‐Modulated Dark Exciton Dynamics

Advanced Science, EarlyView.
This study establishes a direct link between photocatalytic activity, spectroscopic properties, and theoretical analysis of structural effects on exciton behavior in ionic carbon nitrides with different cations. The exciton lifetimes and photocatalytic activity are shown to be primarily related to different dark exciton dynamics governed by changes in ...

Symbiotic Nova PU Vul - 33 Years of Observations

Open Astronomy, 2012
We present UBVRI light curves of the symbiotic nova PU Vul after its outburst in 1978. Three observed eclipses of the hot component by the cool one were used to determine the ephemeris of the binary system as JD (Min I) = 2444550(15) + 4897(10) × E days.

A Universal Doping Strategy for Boosting Luminescence Efficiency of Blue‐Emitting Hybrid Zn Halides as Ultrastable and Underwater Scintillators

Aggregate, EarlyView.
A Pb2+‐doping method is demonstrated to be a universal strategy to realize near‐unity photoluminescence quantum yield and high water‐resistance stability for a family of blue‐emitting zero‐dimensional Zn2+‐based halides through increasing the exciton binding energy and carrier density.

Identification and Characterization of a Novel Biallelic SLC12A2 Variant Associated With Kilquist Syndrome (OMIM #619080)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study presents the case of a child with multiple congenital anomalies, severe hypotonia, and profound bilateral sensorineural hearing loss. Functional bioenergetic assessments showed no significant mitochondrial respiratory defects, and riboflavin (Rf) status evaluation excluded a deficiency in Rf transporters as a cause of hearing loss ...

Development of an efficient mice model of cancer‐associated cardiac cachexia

Animal Models and Experimental Medicine, EarlyView.
This work establishes a preclinical framework for targeting ubiquitin pathways to mitigate the morbidity of cancer‐related cardiopathy. Our integrated approach delineates a hierarchical progression from subcellular dysfunction to macroscopic cardiac deterioration. These findings mechanistically link tumor‐induced cachexia to cardiac dysfunction through

Classification of Metal-Deficient Dwarfs in the Vilnius Photometric System

Open Astronomy, 2003
Methods used for the quantitative classification of metal-deficient stars in the Vilnius photometric system are reviewed. We present a new calibration of absolute magnitudes for dwarfs and subdwarfs, based on Hipparcos parallaxes.
