Phytochemical and Biological Evaluation of Leaves, Stems, and Roots of Schinus weinmanniifolia Mart. Ex Engl. [PDF]

Chem Biodivers
Ethanolic extracts from leaves, stems, and roots of Schinus weinmanniifolia Mart. ex Engl. were evaluated for phytochemical composition and biological activities. The extracts exhibited antioxidant, photoprotective, and antimicrobial activity, without hemolytic effects or cytotoxicity at active concentrations. Syringic acid, epicatechin, and rutin were

Embryonic and juvenile snakes (Natrix maura, Linnaeus 1758) compensate for high elevation hypoxia via shifts in cardiovascular physiology and metabolism

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 10, Page 1102-1115, December 1, 2023., 2023
Hypoxia suppressed heart rates at the end of incubation and altered respiratory quotients of juvenile snakes, but did not affect fitness‐related traits at hatching or at age 1 month. This suggests that embryonic physiological plasticity may facilitate responses to novel environments as species' ranges expand.

Genome‐wide phylogeography reveals cryptic speciation in the circumglobal planktonic calcifier Limacina bulimoides

Molecular Ecology, Volume 32, Issue 12, Page 3200-3219, June 2023., 2023
Abstract Little is known about when and how planktonic species arise and persist in the open ocean without apparent dispersal barriers. Pteropods are planktonic snails with thin shells susceptible to dissolution that are used as bio‐indicators of ocean acidification.

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

Clinical 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),

Defensa comunitaria y culturas del terror: Crimen organizado y violencia de Estado en comunidades originarias de Guerrero, México

The Journal of Latin American and Caribbean Anthropology, Volume 27, Issue 4, Page 564-574, December 2022., 2022
Abstract Rich in raw materials, the state of Guerrero, Mexico, is one of the main enclaves of opium production, mineral extraction, and a focus for the multiplication of armed actors in Latin America, which, together with the overlapping of counterinsurgent violence in the past, post‐colonial violence and the militarization of the policies of the so ...

Carceral spectres: Hyperincarceration and the haunting of Aboriginal life

The Australian Journal of Anthropology, Volume 33, Issue S1, Page 35-45, August 2022., 2022
Abstract Drawing on recent participant observation‐based data from the Northern Territory's Victoria River region, I propose that the coercive and custodial arms of the settler state are predominant features of, and constant and permanent forces of rupture in, remote Aboriginal life.
