Lessons learned from 150 total gastrectomies for prevention of cancer.

Background: Prophylactic total gastrectomy (PTG) is performed in carriers of CDH1 pathogenic and likely pathogenic (P/LP) variants and is becoming more frequent with broader use of germline genetic testing. There is an unmet need to standardize care and enhance outcomes among patients undergoing surgery for the prevention of gastric cancer.

Methods: This was a retrospective analysis of 150 individuals with germline CDH1 P/LP variants who underwent PTG as part of a prospective natural history study from October 2017 to May 2023.

Free-Wilson Analysis of Comprehensive Data on Phosphoinositide-3-kinase (PI3K) Inhibitors Reveals Importance of -Methylation for PI3Kδ Activity.

Phosphoinositide-3-kinase δ (PI3Kδ) is a critical regulator of cell growth and transformation and has been explored as a therapeutic target for a range of diseases. Through the exploration of the thienopyrimidine scaffold, we have identified a ligand-efficient methylation that leads to remarkable selectivity for PI3Kδ over the closely related isoforms. Interrogation through the Free-Wilson analysis highlights the innate selectivity the thienopyrimidine scaffold has for PI3Kδ and provides a predictive model for the activity against the PI3K isoforms.

Ten-year assessment of the 100 priority questions for global biodiversity conservation.

In 2008, a group of conservation scientists compiled a list of 100 priority questions for the conservation of the world's biodiversity. However, now almost a decade later, no one has yet published a study gauging how much progress has been made in addressing these 100 high-priority questions in the peer-reviewed literature. We took a first step toward reexamining the 100 questions to identify key knowledge gaps that remain.

Ecosystem Services from Edible Insects in Agricultural Systems: A Review.

Many of the most nutritionally and economically important edible insects are those that are harvested from existing agricultural systems. Current strategies of agricultural intensification focus predominantly on increasing crop yields, with no or little consideration of the repercussions this may have for the additional harvest and ecology of accompanying food insects. Yet such insects provide many valuable ecosystem services, and their sustainable management could be crucial to ensuring future food security.

Nested Houses: Domestication dynamics of human-wasp relations in contemporary rural Japan.

Background: Domestication is an important and contested concept. Insects are used as food worldwide, and while some have been described as domesticated and even 'semi-domesticated', the assumptions and implications of this designation are not clear. The purpose of this paper is to explore these aspects of insect domestication, and broader debates in domestication studies, through the case of edible wasps in central rural Japan.

Do low-carbon-emission diets lead to higher nutritional quality and positive health outcomes? A systematic review of the literature.

Objective: To evaluate what is known about the relative health impacts, in terms of nutrient intake and health outcomes, of diets with reduced greenhouse gas emissions (GHGE).

Design: We systematically reviewed the results of published studies that link GHGE of dietary patterns to nutritional content or associated consequences for health.

Setting: We included studies published in English in peer-reviewed journals that included data on actual and modelled diets and enabled a matched comparison of GHGE with nutrient composition and/or health outcomes.

Selective insectivory at Toro-Semliki, Uganda: comparative analyses suggest no 'savanna' chimpanzee pattern.

Chimpanzee (Pan troglodytes) insectivory across Africa is ubiquitous. Insects provide a significant nutritional payoff and may be important for chimpanzees in dry, open habitats with narrow diets. We tested this hypothesis at Semliki, Uganda, a long-term dry study site.
