Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).

Diastereoselectivity in the Synthesis of m‐ and p‐Substituted 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐one Sulfoxides With Oxone

Journal of Heterocyclic Chemistry, EarlyView.
Highly selective oxidation of thiazolidin‐4‐ones to sulfoxides and sulfones with Oxone and KMnO4, respectively. ABSTRACT S‐Oxidation of 3‐Aryl‐2‐trichloromethyl‐1,3‐thiazolidin‐4‐ones with Oxone was investigated. For all compounds evaluated, selective oxidation to the sulfoxide versus the sulfone was realized using 3 equivalents of Oxone at room ...

Galaxy mergers in a fractal cosmology

European Physical Journal C: Particles and Fields
This work discusses the influence of galaxy mergers in the evolution of a parabolic Lemaître–Tolman–Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive single fractal galaxy distributions systems possessing fractal dimension D ...

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, EarlyView.
Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Buzzard to Cardinal: Improved Mock Catalogs for Large Galaxy Surveys

The Astrophysical Journal
We present the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including the Dark Energy Survey (DES), DESI, and LSST.

AMPK‐Dependent Epigenetic Regulation of Metabolism Mediates the Anti‐Cancer Action of Pterostilbene in Hepatocellular Carcinoma

Molecular Nutrition &Food Research, EarlyView.
This study investigates the anti‐cancer effects of pterostilbene (PTS), a naturally occurring dietary phytoestrogen, in a rat model of hepatocellular carcinoma (HCC) induced by a choline‐deficient L‐amino acid‐defined (CDAA) diet. Supplementation with PTS significantly reduces liver steatosis and tumor formation.

Stacking and Analyzing MOSDEF Galaxies by Spectral Types: Implications for Dust Geometry and Galaxy Evolution

The Astrophysical Journal
We examine star formation and dust properties for a sample of 660 galaxies at 1.37 ≤ z ≤ 2.61 in the MOSDEF survey by dividing them into groups with similarly shaped spectral energy distributions (SEDs).

Chandra Observations of the Interacting NGC 4410 Galaxy Group

, 2003
We present high resolution X-ray imaging data from the ACIS-S instrument on the Chandra telescope of the nearby interacting galaxy group NGC 4410. Four galaxies in the inner portion of this group are clearly detected by Chandra, including the peculiar ...
