A new study reveals that factors present in aged blood can accelerate the accumulation of amyloid proteins and influence behavior in an experimental mouse model of Alzheimer's. The study found more than 250 differentially expressed proteins linked to synaptic functions, endocannabinoid signaling, and calcium channels.
A study has identified KPC-type carbapenemase-producing bacteria in Chilean wastewater, raising concerns about environmental circulation of microorganisms with high antibiotic resistance levels. The finding emphasizes the need for surveillance within the framework of
A natural experiment-based study in Chile found a significant impact of the COVID-19 pandemic on maternal mortality from non-respiratory causes. The study revealed an increase in indirect obstetric causes, possibly linked to comorbidities such as diabetes and hypertension.
Researchers identified key factors contributing to long-term lung dysfunction in COVID-19 patients, including hypoxia, systemic inflammation and metabolic syndrome. The study highlights the importance of multidisciplinary treatment approaches for individuals with LONG-COVID.
A research study led by Mabel Vidal identified a common genetic signature among infiltrating T cells of different cancer types. The study used AI to analyze data from public repositories and confirmed the results through proteomics experiments.
Researchers developed a risk algorithm specific to the region, incorporating factors such as age, cholesterol level, and blood pressure. The new score aims to provide greater accuracy in identifying people at high risk of cardiovascular disease in clinical practice.
Research reveals Patagonian sheepdogs share common traits with European herding breeds, tracing back to extinct UK shepherds. The study uses genomic characterization and DNA sequencing to identify the connection between the two populations.
A natural experiment found that Argentina's vital records detected significant and transient impacts of the 2009 H1N1 influenza pandemic on maternal health. The study also confirmed a decline in direct obstetric causes and an increase in indirect causes due to non-pregnancy comorbidities.
Researchers identified a key mechanism in which tumor microenvironment induces an anti-inflammatory phenotype, promoting tumor growth. The vitamin D signaling pathway plays a crucial role in this process.
A study by Elard Koch reveals that hospital discharges due to abortion complications decreased significantly in Chile since 2001. The decline was attributed to improved maternal health policies and increased women's educational level, rather than changes in abortion laws.
Scientists discuss significant correlations between abortion and coercion, intimate partner violence, psychological consequences, and suicide rates. Countries with restrictive abortion laws display lower abortion rates and maternal mortality rates compared to those with more permissive laws.
