Public knowledge and attitudes toward liver diseases and liver cancer in the Brazilian population: a cross sectional study.

Background: Little is known about the knowledge of the Brazilian population regarding prevention/screening/diagnosis of cirrhosis and hepatocellular carcinoma (HCC). We aimed to investigate the public knowledge/attitudes toward liver diseases in Brazil.

Methods: A cross-sectional survey was conducted in which 1.

The influence of parental high-fat high-sugar diet on the gut-brain axis in male offspring.

Purpose: The gut-brain axis (GBA) is implicated in the development of obesity, and its role in developmental programming needs to be explored. This study uncovers the effects of a parental high-fat, high-sugar diet (HFS) on the gut (colon) and brain (hypothalamus) GBA of male Wistar rat offspring at weaning until adulthood.

Methods: For ten weeks before mating, male progenitors were fed a control diet (CD) or HFS, whereas dams were fed CD or HFS during pregnancy and lactation.

Parental High-Fat High-Sugar Diet Intake Programming Inflammatory and Oxidative Parameters of Reproductive Health in Male Offspring.

Parental nutrition can impact the health of future generations, programming the offspring for the development of diseases. The developing germ cells of the offspring could be damaged by the maternal or the paternal environment. The germ cells in development and their function could be affected by nutritional adversity and therefore, harm the health of subsequent generations.

Parental high-fat high-sugar diet programming and hypothalamus adipose tissue axis in male Wistar rats.

Purpose: Maternal nutrition during early development and paternal nutrition pre-conception can programme offspring health status. Hypothalamus adipose axis is a target of developmental programming, and paternal and maternal high-fat, high-sugar diet (HFS) may be an important factor that predisposes offspring to develop obesity later in life. This study aims to investigate Wistar rats' maternal and paternal HFS differential contribution on the development, adiposity, and hypothalamic inflammation in male offspring from weaning until adulthood.

Obesity-related inflammatory modulation by juçara berry (Euterpe edulis Mart.) supplementation in Brazilian adults: a double-blind randomized controlled trial.

Purpose: Obesity is an inflammatory-related disease, which recruits immune system cells triggering to imbalanced production of cytokines. Obesity management and treatment using foods bioactive compounds have gained clinical and scientific relevance. Juçara (Euterpe edulis Mart.

The Use of Juçara ( Mart.) Supplementation for Suppression of NF-κB Pathway in the Hypothalamus after High-Fat Diet in Wistar Rats.

Obesity is associated with modern diets that are rich in saturated fatty acids. These dietary patterns are linked to low-grade proinflammatory mechanisms, such as the toll-like receptor 4/nuclear factor kappa-B (NF-κB) pathway rapidly activated through high-fat diets. Juçara is a berry rich in anthocyanins and unsaturated fatty acids, which prevents obesity and associated comorbidities.

Fatty-acid-mediated hypothalamic inflammation and epigenetic programming.

A high-fat diet is the main environmental cue that has been studied in the hypothalamus since the discovery of its connection with hypothalamic inflammation. Current evidence shows hypothalamic inflammation as a likely mechanism for the dysregulation on the homeostatic control of energy balance, which leads to metabolic alterations and obesity. Although this mechanism seems to be reversible when set during adulthood, we argue whether dietary fatty acids, during critical periods of development, could affect hypothalamic function permanently and set an increased susceptibility to obesity.

Modeling of an anoxic/methanogenic biofilm: effect of pH calculation within the biofilm.

The models of anoxic/methanogenic processes in biofilm reactors published until now have supposed that pH does not change between the bulk liquid and biofilm. These assumptions are not necessarily valid for processes in reactors with biofilms. The present work studied an anoxic/methanogenic biofilm reactor incorporating the pH variation in both bulk and biofilm.

Marine ecosystem appropriation in the Indo-Pacific: a case study of the live reef fish food trade.

Our ecological footprint analyses of coral reef fish fisheries and, in particular, the live reef fish food trade (FT), indicate many countries' current consumption exceeds estimated sustainable per capita global, regional and local coral reef production levels. Hong Kong appropriates 25% of SE Asia's annual reef fish production of 135 260-286 560 tonnes (t) through its FT demand, exceeding regional biocapacity by 8.3 times; reef fish fisheries demand out-paces sustainable production in the Indo-Pacific and SE Asia by 2.

Evaluation of human exposure to ambient PM10 in the metropolitan area of Mexico City using a GIS-based methodology.

The main goal of this study was to evaluate the magnitude of outdoor exposure to fine particulate matter (PM10) potentially experienced by the population of metropolitan Mexico City. With the use of a geographic information system (GIS), spatially resolved PM10 distributions were generated and linked to the local population. The PM10 concentration exceeded the 24-hr air quality standard of 150 microg/m3 on 16% of the days, and the annual air quality standard of 50 microg/m3 was exceeded by almost twice its value in some places.

Snoring in Portuguese primary school children.

Objective: To determine the prevalence of snoring and its potential associations with sleep problems, such as daytime symptoms, medical conditions, school performance, and behavioral disturbances in Portuguese children attending primary school.

Methods: A previously validated questionnaire was sent to the parents of 1381 children attending primary schools in a parish of Coimbra, Portugal. To assess behavioral disturbances, the Portuguese version of Rutter's Children's Behavior Questionnaire for completion by teachers was used.
