Vole hunting: novel predatory and carnivorous behavior by California ground squirrels.

Unlabelled: Dietary flexibility allows animals to respond adaptively to food pulses in the environment. Here we document the novel emergence of widespread hunting of California voles and carnivorous feeding behavior by California ground squirrels. Over two months in the twelfth year of a long-term study on the squirrel population, we document 74 events of juvenile and adult ground squirrels of both sexes depredating, consuming, and/or competing over vole prey.

Preclinical study investigating the potential of low-dose-rate brachytherapy with P stents for the prevention of restenosis of paranasal neo-ostia.

Purpose: Ostial restenosis is a common cause of failures in paranasal sinus surgery. The aim of the current study was to investigate the use of low-dose-rate brachytherapy to prevent neo-ostial restenosis in an animal model.

Methods And Materials: In 14 rabbits, maxillary neo-ostia were created and measured.

Hidden and Neglected: Food Poverty in the Global North - The Case of Germany.

Although still a powerful economy, Germany faces rising income inequality and food insecurity. Quantitative data show that nutritional poverty in Germany has become a fact, especially for social welfare recipients. This contribution gives an overview and discusses the limits of results from different data sources, such as German food surveys, and addresses how affected population groups are systematically underrepresented.

Ultrasound-assisted enzymatic transesterification of methyl benzoate and glycerol to 1-glyceryl benzoate in organic solvent.

The aim of this work is to report the enzymatic transesterification production of 1-glyceryl benzoate under ultrasound irradiation, using a commercial immobilized lipase, Novozym 435. Firstly, a preliminary evaluation was carried out at 2, 4 and 6h, at constant temperature of 50 °C, methyl benzoate to glycerol molar ratio of 1:1 and 5.5 wt% of enzyme concentration.

Studies on immobilization and partial characterization of lipases from wheat seeds (Triticum aestivum).

The objective of this study was to provide some features on immobilization and partial characterization of lipases from wheat seeds. The optimum pH and temperature were found to be 5.5 and 32-37 °C, respectively.
