Background: The main challenge in new drug development is accurately predicting the human response in preclinical models.

Methods: In this study, we developed three different intestinal barrier models using advanced biofabrication techniques: (i) a manual model containing Caco-2 and HT-29 cells on a collagen bed, (ii) a manual model with a Caco-2/HT-29 layer on a HDFn-laden collagen layer, and (iii) a 3D bioprinted model incorporating both cellular layers. Each model was rigorously tested for its ability to simulate a functional intestinal membrane.

Bimetallic nanoparticles are used in numerous applications in catalysis, plasmonics or fuel cell technology. The addition of the second metal to the nanoparticles allows enhancing and fine-tuning their properties by choosing their composition, size, shape and environment. However, the crucial additional parameter of chemical structure within the particle is difficult to predict and access experimentally, even though segregated core-shell structures and random alloys can have drastically different physicochemical properties.

Contamination with potentially toxic metals and metalloids (PTMs) in mining areas poses significant environment and human health risks. Using biochar as an amendment can be a cost-effective and eco-friendly method to reduce PTM bioavailability in contaminated soils, thus lowering plant uptake. This study investigated biochar derived from the organic fraction of municipal solid waste (OFMSW) at three pyrolysis temperatures (300, 500, and 700 °C) and two application rates (1% and 5%, w/w) for the remediation of slag-contaminated soils from an old environmental liability in the Ribeira Valley (Brazil).

Cancer remains one of the leading causes of mortality worldwide, characterized by uncontrolled cell growth and the ability of tumors to invade surrounding tissues and spread to distant organs. Despite significant advancements in early detection, diagnosis, and treatment, many cancers still present substantial challenges due to their heterogeneity, resistance to conventional therapies, and severe side effects of existing treatments. Consequently, there is an ongoing need for novel therapeutic agents to selectively target cancer cells, enhance the efficacy of current treatments, and minimize adverse effects.

Background: Cancer navigation programs aim to support, educate, and empower patients and families, addressing barriers to diagnostics, treatment, and care. Navigators engage with people to ensure timely access to services and resources. While promising for older people with cancer, these programs are scarce in Europe, and research on their effectiveness and implementation is limited.

Background/objectives: Approximately 25% of the world's population and more than 60% of patients with type 2 diabetes (T2D) have metabolic-dysfunction-associated steatotic liver disease (MASLD). The association between these pathologies is an important cause of morbidity and mortality in Brazil and worldwide due to the high frequency of advanced fibrosis and cirrhosis. The objective of this study was to determine the epidemiologic and clinical-laboratory profile of patients with T2D and MASLD treated at an endocrinology reference service in a state in northeastern Brazil, and to investigate the association of liver fibrosis with anthropometric and laboratory measurements.

Irisin-based interventions have gained attention for their potential to modulate the adenosine monophosphate (AMP)-activated protein kinase (AMPK) pathway in various diseases. Physiologically, irisin is a myokine released during physical exercise that exerts anti-inflammatory effects and is a metabolic and cardiometabolic enhancer. On the other hand, AMPK is crucial for maintaining energy balance and metabolic homeostasis.

Article Synopsis
  • - Type 1 diabetes (T1D) is a chronic condition where the immune system attacks beta cells in the pancreas that produce insulin; C-peptide, released alongside insulin, is a helpful marker for evaluating pancreatic function due to its longer lifespan in the body.
  • - A study involving 95 T1D patients focused on the levels of C-peptide and its relationship with factors like age, revealing that nearly 30% had some remaining insulin secretion, primarily linked to their age at diagnosis.
  • - No significant differences were found in metabolic control or microvascular complications based on C-peptide levels, and it was noted that ancestry did not affect residual C-peptide function; future research should explore additional factors like HLA and pancreatic auto

Introduction: Pituitary adenomas (PAs) are benign tumors with high prevalence and, occasionally, aggressive course. The tumorigenesis of these lesions is not completely understood at the molecular level. BAK1 and BAX proteins play fundamental roles in apoptosis and seem to interact with VDAC proteins, whose expressions have been markedly altered in cancer, impacting their prognosis.
