Oxidative Addition of Aryl Bromides at Palladium(I) to form Palladium(III) Complexes. [PDF]

Angew Chem Int Ed Engl
This work reveals a detailed mechanistic study of the oxidative addition of aryl bromides to a Pd(I) center to generate an isolable Pd(III) species. UV–vis and cryo stopped‐flow kinetic studies, including Eyring and Hammett analyses, reveal a rapid oxidative addition step occurring at a Pd(I) center, and a zero‐order dependence on the substrate ...

Endothelial cellular senescence and tau accumulation: An interplay full of opportunities? [PDF]

Ibrain
Recent research has shown that tau protein can be passed to neighbouring cells, leading to cellular senescence in the endothelial cells present in the central nervous system (CNS). This discovery could potentially open new doors for testing novel therapeutic compounds that specifically target senescent cells (senolytics), or for identifying new ...

Antibiotic Susceptibility of Zoonotic Bacteria Isolated From Oral Cavities of Indigenous Dogs From Semi-Urban Areas in Uganda. [PDF]

Vet Med Sci
Dog bites lead to bacterial infections. Isolation and identification of zoonotic bacterial species from the oral cavities of indigenous dogs using biochemical tests were carried out. The antibiotic susceptibility profile of the commonly identified bacteria species was established using Kirby–Bauer disk diffusion approach.

Sexually dimorphic developmental changes in rat spinal cord pain pathways following neonatal inflammation. [PDF]

Physiol Rep
Abstract Early‐life inflammation has a long‐lasting impact on pain behaviors, with neonatal inflammation resulting in altered pain behaviors throughout life. Possible mechanisms underlying these changes lie within the first and second order neurons in the pain neuroaxis. We investigated neuroinflammatory markers in dorsal root ganglia (DRGs) and spinal

Is the third coefficient of the Jones knot polynomial a quantum state of gravity? [PDF]

, 1995
Some time ago it was conjectured that the coefficients of an expansion of the Jones polynomial in terms of the cosmological constant could provide an infinite string of knot invariants that are solutions of the vacuum Hamiltonian constraint of quantum ...

Extended Loops: A New Arena for Nonperturbative Quantum Gravity [PDF]

, 1993
We propose a new representation for gauge theories and quantum gravity. It can be viewed as a generalization of the loop representation. We make use of a recently introduced extension of the group of loops into a Lie Group.

La adopción de modelos foráneos en la Ibiza púnica: dos moldes para la elaboración de terracotas hallados en la isla [PDF]

Boletín del Museo Arqueológico Nacional, 2017
Presentamos dos moldes para la producción de figuras femeninas de terracota, hallados en Ibiza. Su estudio da pie para plantear algunas cuestiones sobre los procesos de fabricación, la iconografía de las representaciones, así como la adopción y ...

La traducción al árabe entre la mediación lingüística y la difícil asimilación cultural en el periodo abasí

Trans, 2020
Durante la Alta Edad Media, el movimiento de traducción hacia el árabe, fuera transmisión directa o indirecta contando con la mediación de otras lenguas como el siríaco o el persa, no sólo fue una cuestión de traslación de textos, sino un proceso de ...
