The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Globalisation and Food Sovereignty: Impact of Foreign Direct Investments and Government Expenditure in Ghana in 2001–2010

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The article looks at the globalisation effects on food availability in Ghana. The aim of the article is to analyse which of the selected macroeconomic indicators have a statistically significant impact on the increase of food availability in the country.

Availability of junk food should be reduced

BMJ, 2012
Prison inmates rely on two sources of food—main meals (provided by the prison) and items purchased from the canteen,1 2 the penal equivalent of a convenience store. Prison meals meet nutritional guidelines, but purchased items—much of it “junk” food—may not.3We analysed macronutrient and energy content of food available in a canteen from …

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Covid-19 and the Subsequent Lockdown Modified Dietary Habits of Almost Half the Population in an Italian Sample

Foods, 2020
The Covid-19 pandemic led to lockdowns in several parts of the world and, hence, changed some daily habits, including social interactions, the ability to perform sports, and—possibly—diet.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A systematic review of food deserts, 1966-2007. [PDF]

, 2009
INTRODUCTION: "Food deserts," areas characterized by poor access to healthy and affordable food, may contribute to social and spatial disparities in diet and diet-related health outcomes. However, the extent to which food deserts exist is debated.

Individual-based modelling of elephant population dynamics using remote sensing to estimate food availability [PDF]

, 2018
Strategies for the conservation and management of many wild species requires an improved understanding of how population dynamics respond to changes in environmental conditions, including key drivers such as food availability.
