Synthesis of Five‐Membered Heterocycle Fused Quinazolinone Via Buchwald–Hartwig Cross Coupling Reaction

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Efficient Buchwald‐Hartwig cross‐coupling reactions were utilized to synthesize quinazolinone derivatives with a five‐membered heterocyclic ring substituted onto the quinazolinone structure, through reactions with various 2‐amino pyridine derivatives. This synthetic method is applicable to a total of six different five‐membered heterocyclic compounds ...

Spexin in the European sea bass, Dicentrarchus labrax: Characterization, brain distribution, and interaction with Gnrh and Gnih neurons

open access: yesJournal of Comparative Neurology, Volume 531, Issue 2, Page 314-335, February 2023., 2023
The main objective of this work was to obtain detailed information on the distribution and localization of the spexin (Spx) system in the sea bass brain. To this purpose, we first identified and characterized the spx1 gene and analyzed its expression in the central nervous system (CNS) of the European sea bass by using quantitative Real‐Time Polymerase

Accretion process of the moon [PDF]

open access: yes
Recent geochemical and geophysical data suggest that the initial temperature of the moon was strongly peaked toward the lunar surface. To explain such an initial temperature distribution, a simple model of accretion process of the moon is presented.

The Association of the Moon and the Sun with Large Earthquakes [PDF]

open access: yesarXiv, 2012
The role of the moon in triggering earthquakes has been studied since the early 1900s. Theory states that as land tides swept by the moon cross fault lines, stress in the Earth's plates intensifies, increasing the likelihood of small earthquakes. This paper studied the association of the moon and sun with larger magnitude earthquakes (magnitude 5 and ...

The comparative evaluation of the effects of quercetin, α‐tocopherol, and chlorhexidine dentin pretreatments on the durability of universal adhesives

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1638-1644, December 2022., 2022
Abstract Objective The aim of this study was to evaluate and compare the effects of chlorhexidine, quercetin, and α‐tocopherol on the shear bond strength of universal adhesives in the short (24h) and long term (6 months). Material and Methods Ninety‐six extracted sound molars were collected and divided randomly into four groups: control (no treatment),

Binocular disparity as an explanation for the moon illusion [PDF]

open access: yesarXiv, 2013
We present another explanation for the moon illusion, the phenomenon in which the moon looks larger near the horizon than near the zenith. In our model of the moon illusion, the sky is considered a spatially-contiguous and geometrically-smooth surface.
