Earliest evidence of granivory from China (Shanxi Formation) points to seeds as a food source and nursing habitat for insects in the earliest Permian humid tropical forests of Cathaysia

by Artai A. Santos, Torsten Wappler, Stephen McLoughlin

Three types of plant-insect interactions are identified on seeds from the lower Permian (Asselian) Shanxi and lower Shihhotse formations of the Taiyuan district, North China. This enhances the relatively meagre fossil record of seed predation in global late Paleozoic floras, adding the earliest record of granivory from Cathaysia. The dispersed seeds cannot be attributed with confidence to any particular plant group, but associated fossil leaves belong to a broad spectrum of plants... Читать дальше...

Depot-specific mRNA expression programs in human adipocytes suggest physiological specialization via distinct developmental programs

by Heather J. Clemons, Daniel J. Hogan, Patrick O. Brown

Adipose tissue is distributed in diverse locations throughout the human body. Not much is known about the extent to which anatomically distinct adipose depots are functionally distinct, specialized organs, nor whether depot-specific characteristics result from intrinsic developmental programs, as opposed to reversible physiological responses to differences in tissue microenvironment. We used DNA microarrays to compare mRNA expression... Читать дальше...

Tropical forest cover, oil palm plantations, and precipitation drive flooding events in Aceh, Indonesia, and hit the poorest people hardest

by Muhammad Irfansyah Lubis, Matthew Linkie, Janice Ser Huay Lee

Tropical forest loss and degradation in watersheds disrupt essential ecosystem services that regulate water flow, often causing devastating floods that impact agricultural productivity and impoverish downstream communities. Despite its importance, evaluations of the interconnectedness between the depletion of hydrological services and flooding lack an evidence-base in the Global South and, therefore, have little influence on policy dialogue.

Korean Triage and Acuity Scale education using role-playing and its effects on triage competency: A quasi-experimental design

by Yon Hee Seo, Sun-Og Lim

Triage is the process of prioritizing patients in the emergency department (ED). This has a pivotal role in ensuring patient safety and that the ED operates smoothly; therefore, triage training education is an important aspect of triage nurses’ preparedness in different emergency situations. This study employed a quasi-experimental research design using a non-equivalent control group pre–post-test design to verify the effect of the Korean Triage and Acuity Scale... Читать дальше...

Memory modulation: Dominance of negative visual context over neutral verbal memory

by Stas Kozak, Noa Herz, Maya Tocker, Yair Bar-Haim, Nitzan Censor

Neutral memories can be modulated via intentional memory control paradigms such as directed forgetting. In addition, previous studies have shown that neutral visual memories can be modulated indirectly, via remember and forget instructions towards competing verbal memories. Here we show that direct modulation of neutral verbal memory strength is impaired by negative visual context, and that negative visual context is resistant to indirect memory modulation.

Using multivariate partial least squares on fNIRS data to examine load-dependent brain-behaviour relationships in aging

by Claudia Gonzalez, Supreeta Ranchod, Mark Rakobowchuk

Researchers implementing non-invasive neuroimaging have reported distinct load-dependent brain activity patterns in older adults compared with younger adults. Although findings are mixed, these age-related patterns are often associated with compensatory mechanisms of cognitive decline even in the absence of direct comparisons between brain activity and cognitive performance. This study investigated the effects of cognitive load on brain-behavior... Читать дальше...
