Phosphine oxide reduction with silanes is governed by phosphine oxide distortion and silane interaction energies. In R3SiH silanes, NBO analysis reveals that n(O)→σ*(SiR) donation is distributed among several acceptor orbitals, whereas in Ph2RSiH silanes, small electronegative substituents directly bonded to silicon (RCl, OCN, OH) enhance the σ ...

Parasite–Host Associations in Pinworms (Trypanoxyuris spp.) From Spider Monkeys (Ateles spp.)
Lineages in pinworms from Ateles monkeys are highly host‐specific and their diversification patterns reflect host biogeographic and evolutionary histories. ABSTRACT Pinworms of primates are highly host‐specific parasites that, in several lineages, are known to share their evolutionary history with that of their hosts.

Eryngium heterophyllum has 85 metabolites according to nontargeted UHPLC‐QTOF‐MS profiling, with flavonoids and phenylpropionic acids emerging as significantly related bioactive families. In silico compound–disease–target networks connect 31 metabolites to inflammation, diabetes, obesity, and cardiovascular disease associated with metabolic syndrome ...

A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

Problema de ajustes del año calendárico mesoamericano al año trópico
En varios estudios recientes se ha argumentado que el año calendárico mesoamericano mantenía una correlación fija con el año trópico; también se han propuesto distintos métodos de ajustes periódicos mediante los cuales se habría logrado esta concordancia
