Impact of Geography on Institutions in Agricultural and Nomadic Societies

International Studies of Economics, EarlyView.
ABSTRACT How geography affects the choice of institutions is studied in a theoretical model. In this model, nations are located around a circle. Rulers compete through choosing tax rates, the level of military spending, and the degree of formality of institutions. Geographic condition is captured by population density.

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Pre‐operative transcranial Doppler ultrasound assessment of cerebral collateral circulation in children undergoing veno‐arterial extracorporeal membrane oxygenation or cardiac surgery

Journal of Medical Radiation Sciences, EarlyView.
A pre‐cannulation survey of the circle of Willis (CoW) using transcranial Doppler (TCD) ultrasound was implemented to assess cerebral collateral circulation in children undergoing VA ECMO or cardiac surgery with cervical cannulation. The technique, in use since 2019, employs high‐end ultrasound platforms to assess brain morphology, haemorrhage and ...

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

Acidification of Biogas Residues Stimulates Manganese Uptake in Wheat

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Efficient application of organic fertilizers contributes to resource‐efficient agriculture. Acidification of liquid manure effectively reduces ammonia (NH3) emissions. However, the effect of acidification on other plant nutrients, such as Mn, often a yield‐limiting nutrient in cereal production, is not well understood.
