Biomonitoring of firefighters' exposure to priority pollutant metal(loid)s duri...

Wildland firefighters are exposed to metal(loid)s released during wildfires through vegetation combustion, which also promotes remobilization of accumulated anthropogenic metal(loid)s. Studies biomonitoring metal(loid)s exposure promoted exclusively by wildfire suppression activities are lacking. This work aimed to characterize, for the first time, the impact of real-life wildland firefighting operations on uri...

Exploring geographical influences on physicochemical characteristics of honey: ...

Objectives In recent years, there has been a substantial increase in the global consumption of honey, driven by the high demand for natural products that offer health benefits. Consequently, consumers show a preference for honey, recognised for its superior quality, namely honey with a Protected Designation of Origin (PDO) or honey produced in protected areas, as it is associated with superior attributes and ch...

Uncovering the effects of copper feed supplementation on the selection of coppe...

Glycoproteomics identifies HOMER3 as a potentially targetable biomarker trigger...

Background: Muscle invasive bladder cancer (MIBC) remains amongst the deadliest genitourinary malignancies due to treatment failure and extensive molecular heterogeneity, delaying effective targeted therapeutics. Hypoxia and nutrient deprivation, oversialylation and O-glycans shortening are salient features of aggressive tumours, creating cell surface glycoproteome fingerprints with theranostics potential. Meth...

Target score—a proteomics data selection tool applied to esophageal cancer iden...

Esophageal cancer (EC) is a life-threatening disease, demanding the discovery of new biomarkers and molecular targets for precision oncology. Aberrantly glycosylated proteins hold tremendous potential towards this objective. In the current study, a series of esophageal squamous cell carcinomas (ESCC) and EC-derived circulating tumor cells (CTCs) were screened by immunoassays for the sialyl-Tn (STn) antigen, a g...

Nucleolin-sle a glycoforms as E-selectin ligands and potentially targetable bio...

Background: Gastric cancer (GC) is a major health burden worldwide, with half of patients developing metastases within 5 years after treatment, urging novel biomarkers for diagnosis and efficient therapeutic targeting. Sialyl-Lewis A (SLeA), a terminal glycoepitope of glycoproteins and glycolipids, offers tremendous potential towards this objective. It is rarely expressed in healthy tissues and blood cells, whi...

Protein glycosylation and tumor microenvironment alterations driving cancer hal...

Decades of research have disclosed a plethora of alterations in protein glycosylation that decisively impact in all stages of disease and ultimately contribute to more aggressive cell phenotypes. The biosynthesis of cancer-associated glycans and its reflection in the glycoproteome is driven by microenvironmental cues and these events act synergistically toward disease evolution. Such intricate crosstalk provide...

Experiences During a Psychoeducational Intervention Program Run in a Pediatric ...

Hospitalization, despite its duration, is likely to result in emotional, social, and academic costs to school-age children and adolescents. Developing adequate psychoeducational activities and assuring inpatients' own class teachers' collaboration, allows for the enhancement of their personal and emotional competences and the maintenance of a connection with school and academic life. These educational programs ...

CD44 glycoprotein in cancer: A molecular conundrum hampering clinical applications

CD44 is a heavily glycosylated membrane receptor playing a key role in cell adhesion, signal transduction and cytoskeleton remodelling. It is also one of the most studied glycoproteins in cancer, frequently explored for stem cell identification, and associated with chemoresistance and metastasis. However, CD44 is a general designation for a large family of splicing variants exhibiting different degrees of glyco...
