High hydrostatic pressure (HHP) is an emerging technology that can be applied to improve the functional properties of emulsified meat products. The aim of this study was to evaluate the effect of HHP (100 and 200 MPa) on low-sodium mortadella produced with high content of mechanically deboned poultry meat (MDPM). Seven treatments were produced: FC (2.

Background: Due to the ongoing organ shortage, marginal grafts with steatosis are more frequently used in liver transplantation, leading to higher occurrences of graft dysfunction. A histological analysis is the gold standard for the quantification of liver steatosis (LS), but has its drawbacks: it is an invasive method that varies from one pathologist to another and is not available in every hospital at the time of organ procurement. This study aimed to compare non-invasive diagnostic tools to a histological analysis for the quantification of liver steatosis.

The implementation of non-invasive PGT-A offers a new strategy to genetically assess the preimplantation embryo and to enhance IVF results. The extraction of DNA from the embryo culture medium has been sufficiently demonstrated, and the ability to obtain chromosomal information as a result is particularly interesting. As morphological criteria have proven to have a weak correlation with embryo ploidy status, this technique emerges as a promising alternative for embryo selection.

Article Synopsis
  • - The study aimed to evaluate a software designed for tracking oncological CT scans in the Radiology department using data from 37 cancer patients.
  • - Findings showed no major differences between the software's assessments and traditional PACS reports regarding tumor responses, though some discrepancies were noted in a few cases related to lesion evaluations.
  • - The conclusion suggests that this specialized software could enhance efficiency and diminish human errors in interpreting follow-up CT scans for cancer patients.

  • Teachers' voices are essential tools for their work, but voice disorders can significantly affect their teaching effectiveness and overall well-being.* -
  • A study involving interviews with 18 teachers identified six key themes, including the importance of vocal health, the impact of working conditions, and the need for better resources and training in vocal care.* -
  • The findings underscore that vocal health not only affects teaching quality but also influences teachers' self-image and emotional well-being, indicating a need for comprehensive support systems.*

Article Synopsis
  • Leishmaniasis is a serious disease that's hard to control because there are no vaccines, the medicines can be toxic, and some parasites have become super strong against treatments.
  • Researchers want to find a simple way to study how Leishmania interacts with cells, and they think Acanthamoeba, tiny organisms similar to the cells Leishmania infects, could help.
  • The study showed that Leishmania can infect and multiply inside Acanthamoeba without harming them, which means Acanthamoeba might be useful for understanding Leishmania infections better.

In recent years, many countries have significantly increased military spending, mainly due to geopolitical instability in several regions and the potential risk of armed conflicts spreading worldwide. In this context, understanding the nutritional needs of soldiers in different climates (warm, cold and high altitude) is important and directly impacts the performance and health of soldiers, especially in extreme environments. The amount of liquids, calories, and macro- and micronutrients contained in military rations must be determined considering the type of exercise, duration and environment.

This work investigates the interaction between gas channels in a vertical Hele-Shaw cell when air is injected simultaneously from two points at a constant flow rate. Unlike single-injection experiments, this dual-point system induces the formation of numerous bubbles, thereby intensifying the interactions between air channels. We use an image analysis technique for tracking motion in the granular bed to define a flow density parameter throughout the cell.

Faecal contamination is a widespread environmental and public health problem on recreational beaches around the world. The implementation of predictive models has been recommended by the World Health Organization as a complement to traditional monitoring to assist decision-makers and reduce health risks. Despite several advances that have been made in the modeling of faecal coliforms, tools and algorithms from machine learning are still scarcely used in the field and their implementation in nowcast systems is delayed.

The exposome approach, emphasizing lifelong environmental exposures, is a holistic framework exploring the intricate interplay between genetics and the environment in shaping health outcomes. Complementing this, the one health approach recognizes the interconnectedness of human and ecological health within a shared ecosystem, extending to planetary health, which encompasses the entire planet. Integrating Disease Surveillance Systems with exposome, one health, and planetary health signifies a paradigm shift in health management, fostering a comprehensive public health framework.

Article Synopsis
  • The increase in global wildfires, driven by climate change and land use changes, reached a critical peak in February 2024, when a devastating wildfire affected central Chile, particularly the Valparaíso region, resulting in massive destruction and loss of life.
  • An air quality monitoring campaign on the campus of Federico Santa María Technical University collected unprecedented data during the wildfires, showing extremely high concentrations of black carbon (BC) and particulate matter (PM), significantly exceeding both Chilean and World Health Organization air quality standards.
  • The study highlights the rapid decline in air quality during wildfire events, with pollution levels remaining elevated for days afterward, emphasizing the severe consequences of climate change on public health and the environment.

To continue sleep research activities during the lockdown resulting from the COVID-19 pandemic, experiments that were previously conducted in laboratories were shifted to the homes of volunteers. Furthermore, for extensive data collection, it is necessary to use a large number of portable devices. Hence, to achieve these objectives, we developed a low-cost and open-source portable monitor (PM) device capable of acquiring electroencephalographic (EEG) signals using the popular ESP32 microcontroller.

Inclusive education involves the interaction of diverse actors from different societal sectors, such as education, health, and policy. Inclusion laws and regulations in Chile are relatively new and have been taken as a regional model. However, the efforts to implement them have revealed some structural difficulties that must be discussed.

Background: Internal hemorrhoids (IH) is a common medical condition that can result in morbidity secondary to bleeding and discomfort. Treatment for IH has traditionally consisted of dietary and conservative medical management, focal treatments including banding and sclerotherapy or hemorrhoidectomy. Recently, rectal artery embolization (RAE) has been studied as a potential treatment for bleeding predominant IH.

Introduction: Age-related hearing loss is an important risk factor for cognitive decline. However, audiogram thresholds are not good estimators of dementia risk in subjects with normal hearing or mild hearing loss. Here we propose to use distortion product otoacoustic emissions (DPOAEs) as an objective and sensitive tool to estimate the risk of cognitive decline in older adults with normal hearing or mild hearing loss.

A selenium-containing metal-organic framework with remarkable antioxidant capacity and ROS-scavenging activity was constructed by a controlled encapsulation approach of a glycoconjugate mimetic, specifically a sp-iminoglycolipid bearing a selenoureido fragment (DSeU), within a zeolitic-imidazolate framework exoskeleton. Biocompatible and homogeneous nanosized particles of ∼70 nm (DSeU@ZIF8) were obtained, which could be efficiently internalized in cells, overcoming the poor solubility in biological media and limited bioavailability of glycolipids. The ZIF-particle served as nanocarrier for the intracellular delivery of the selenocompound to cells, promoted by the acidic pH inside endosomes/lysosomes.
