Metabolic Derangement of Essential Transition Metals and Potential Antioxidant Therapies.

Essential transition metals have key roles in oxygen transport, neurotransmitter synthesis, nucleic acid repair, cellular structure maintenance and stability, oxidative phosphorylation, and metabolism. The balance between metal deficiency and excess is typically ensured by several extracellular and intracellular mechanisms involved in uptake, distribution, and excretion. However, provoked by either intrinsic or extrinsic factors, excess iron, zinc, copper, or manganese can lead to cellular damage upon chronic or acute exposure, frequently attributed to oxidative stress.

Copper impairs the intestinal barrier integrity in Wilson disease.

In Wilson disease (WD), liver copper (Cu) excess, caused by mutations in the ATPase Cu transporting beta (ATP7B), has been extensively studied. In contrast, in the gastrointestinal tract, responsible for dietary Cu uptake, ATP7B malfunction is poorly explored. We therefore investigated gut biopsies from WD patients and compared intestines from two rodent WD models and from human ATP7B knock-out intestinal cells to their respective wild-type controls.

A Healthy Liver Will Always Deliver: Impact Study of a Non-Alcoholic Fatty Liver Disease (NAFLD) Awareness Comic.

Based on previous work, we developed the comic "A healthy liver will always deliver!" to raise awareness about Non-Alcoholic Fatty Liver Disease (NAFLD) and promote healthy lifestyles. An online pre-post questionnaire design demonstrated an increase in health-threat beliefs regarding NAFLD among the general public, as well as response efficacy and self-efficacy beliefs, normative and control beliefs regarding the maintenance of preventive strategies involving healthy diets and active lifestyles, after interaction with the comic's narrative. This effect was more evident in women.

Towards symbiotic approaches between universities, sustainable development, and cities.

Universities are key actors and play a central role in the cities which host them, either as employers, consumers or simply as a magnet to young people and cultural activities. They can be also influencers and supporters of cities in the field of sustainable development. Through an exploratory method and aiming to explore the efforts deployed to foster closer links between universities, sustainable development, and cities and address a literature gap in this regard, this study considers the contribution of universities to sustainable development at the city level.

Deploying digitalisation and artificial intelligence in sustainable development research.

Many industrialised countries have benefited from the advent of twenty-first century technologies, especially automation, that have fundamentally changed manufacturing and industrial production processes. The next step in the evolution of automation is the development of artificial intelligence (AI), i.e.

Unhealthy lifestyles, environment, well-being and health capability in rural neighbourhoods: a community-based cross-sectional study.

Background: Non-communicable diseases are a leading cause of health loss worldwide, in part due to unhealthy lifestyles. Metabolic-based diseases are rising with an unhealthy body-mass index (BMI) in rural areas as the main risk factor in adults, which may be amplified by wider determinants of health. Changes in rural environments reflect the need of better understanding the factors affecting the self-ability for making balanced decisions.

Mushrooms on the plate: Trends towards NAFLD treatment, health improvement and sustainable diets.

Non-alcoholic fatty liver disease (NAFLD) is a most important cause of liver disease. Similar to other non-communicable diseases (NCD), such as obesity and type II diabetes mellitus, NAFLD can strongly affected by diet. Diet-related NCD and malnutrition are rising in all regions being a major cause of the global health, economic and environmental burdens.

The use of comics to promote health awareness: A template using nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) constitutes a major threat to public health systems worldwide on account of its widespread prevalence and increasing incidence. More effective tools to raise awareness and increase health communication are therefore needed. Comics may constitute an effective language for this purpose, given the permanence, adaptability and ability of this form of communication to convey complex information, using both visual components and the creation of narrative involvement, thus promoting both awareness and health-conscious behaviours.

COVID-19: the impact of a global crisis on sustainable development research.

The crisis caused by COVID-19 has affected research in a variety of ways. As far as research on sustainable development is concerned, the lockdown has significantly disrupted the usual communication channels and, among other things, has led to the cancellation of meetings and long-planned events. It has also led to delay in the delivery of research projects.

Insights from qualitative research on NAFLD awareness with a cohort of T2DM patients: time to go public with insulin resistance?

Background: It is estimated that around 70% of Type 2 Diabetes Mellitus patients (T2DM) have Non-Alcoholic Fatty Liver Disease (NAFLD). Awareness and education are amongst the major shortcomings of the public health response to the increasing threat of NAFLD. Characterizing the specific NAFLD-related information needs of particular high-risk metabolic communities, for instance, T2DM patients, might aid in the development of evidence-based health promotion strategies, ultimately promoting NAFLD-awareness, treatment adherence and therapeutic success rates.

Antioxidant Versus Pro-Apoptotic Effects of Mushroom-Enriched Diets on Mitochondria in Liver Disease.

Mitochondria play a central role in non-alcoholic fatty liver disease (NAFLD) progression and in the control of cell death signalling during the progression to hepatocellular carcinoma (HCC). Associated with the metabolic syndrome, NAFLD is mostly driven by insulin-resistant white adipose tissue lipolysis that results in an increased hepatic fatty acid influx and the ectopic accumulation of fat in the liver. Upregulation of beta-oxidation as one compensatory mechanism leads to an increase in mitochondrial tricarboxylic acid cycle flux and ATP generation.

Use of lignocellulosic wastes of pecan (Carya illinoinensis) in the cultivation of Ganoderma lucidum.

Background: The wastes of pecan nut (Carya illinoinensis (Wangenh.) K. Koch) production are increasing worldwide and have high concentrations of tannins and phenols.

Development, optimization and application of an analytical methodology by ultra performance liquid chromatography-tandem mass spectrometry for determination of amanitins in urine and liver samples.

Amanitins, highly toxic cyclopeptides isolated from various Amanita species, are the most potent poisons accounting for the hazardous effects on intestinal epithelium cells and hepatocytes, and probably the sole cause of fatal human poisoning. The present study was focused on the development, optimization and application of an analytical methodology by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), following urine and liver sample preparation by protein precipitation with organic solvents, and solid phase extraction (SPE) procedure, for the determination of the amatoxins, α- and β-amanitin. Linearity, detection and quantification limits, selectivity, sensitivity, intra and inter-assay precision and recovery were studied, in order to guarantee reliability in the analytical results.

Land use practices and ectomycorrhizal fungal communities from oak woodlands dominated by Quercus suber L. considering drought scenarios.

Oak woodlands in the Mediterranean basin have been traditionally converted into agro-silvo-pastoral systems and exemplified sustainable land use in Europe. In Portugal, in line with the trend of other European countries, profound changes in management options during the twentieth century have led to landscape simplification. Landscapes are dynamic and the knowledge of future management planning combining biological conservation and soil productivity is needed, especially under the actual scenarios of drought and increasing evidence of heavy oak mortality.
