O Tratado sobre a Proibição de Armas Nucleares (TPAN): inovação no desarmamento nuclear ou esforço inócuo?

open access: yesMeridiano 47 - Journal of Global Studies, 2019
O Tratado sobre a Proibição de Armas Nucleares (TPAN) foi aberto para assinaturas em 2017, e em outubro de 2019 o tratado tinha 79 signatários. No entanto, nenhum Estado Nuclearmente Armado assinou o tratado. Este artigo argumenta que o TPAN é tanto uma inovação no regime de não proliferação de armas nucleares quanto um tratado inadequado para atingir ...

Electrochemical and Spectroscopic Studies on Triarylamine‐Polychlorotriphenylmethyl Dyads with Particularly Strong Triarylamine Donors

open access: yesEuropean Journal of Organic Chemistry, Volume 2021, Issue 33, Page 4690-4700, September 7, 2021., 2021
Two new donor‐acceptor dyads with a particular electron‐rich triarylamine (TAA) donor and the perchlorotriphenylmethyl radical acceptor (PCT) are probed for their propensity to equilibrate with their zwitterionic valence tautomers TAA+‐PCT−. The UV/vis/NIR and EPR spectroscopic profiles of their oxidized and reduced forms were recorded, but failed to ...

A Procedural Transhiatal Approach for the Thoracic Para-Aortic Lymph Node: A Case Report. [PDF]

open access: yesAsian J Endosc Surg
ABSTRACT The thoracic posterior para‐aortic lymph node (TPAN) is classified as an extra‐regional lymph node in esophageal cancer, with metastasis indicating poor prognosis. However, some cases with suspected TPAN metastasis may benefit from esophagectomy with lymph node dissection, including TPAN. This report presents the case of a 58‐year‐old man with

Omega‐6: Its Pharmacology, Effect on the Broiler Production, and Health

open access: yesVeterinary Medicine International, Volume 2023, Issue 1, 2023., 2023
Lipids and oils are the primary sources of monounsaturated and polyunsaturated fatty acids (MUFA and PUFA), which are necessary for human and animal health. Omega‐3 and omega‐6 are essential nutrients for broilers. Omega‐6 members, such as linolenic acid, are essential for broilers and must be obtained through feed.

Soils in ancient irrigated agricultural terraces in the Atacama Desert, Chile

open access: yesGeoarchaeology, Volume 37, Issue 1, Page 96-119, January/February 2022., 2022
Abstract The Atacama Desert is among the driest places on Earth, yet ancient agricultural systems are present in the region. Here, we present a study of terraced agricultural soils in the high‐altitude eastern margin of the Atacama Desert in northern Chile, mainly dating to the Late Intermediate Period (ca. 950–1400 AD) and Inka period (ca.

Overconsumption of Omega‐6 Polyunsaturated Fatty Acids (PUFAs) versus Deficiency of Omega‐3 PUFAs in Modern‐Day Diets: The Disturbing Factor for Their “Balanced Antagonistic Metabolic Functions” in the Human Body

open access: yesJournal of Lipids, Volume 2021, Issue 1, 2021., 2021
Polyunsaturated fatty acids (PUFAs) contain ≥2 double‐bond desaturations within the acyl chain. Omega‐3 (n‐3) and Omega‐6 (n‐6) PUFAs are the two known important families in human health and nutrition. In both Omega families, many forms of PUFAs exist: α‐linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) from the n‐3 ...
