Cryptococcosis predominantly affects immunocompromised individuals, particularly those with advanced HIV disease, with meningitis being the most severe form and linked to high mortality. Diagnosis typically relies on rapid Cryptococcus antigen (CrAg) testing, and antigen titer quantification helps in early detection and assessing disease severity. However, conventional titer methods are often more expensive than qualitative antigen detection.

However, their environmental and economic impact in the tropical region of Peru has been scarcely studied. The CLEANED tool, developed by the Alliance of Bioversity International and the International Center for Tropical Agriculture, allows us to assess the productive situation and the environmental and economic impact of different dairy systems.

- Nanometer-scale control over the surface functionalization of soft gels is crucial for applications in cell culture and regenerative medicine.
- Researchers have demonstrated the ability to transfer a precision polymer layer to the surface of stiff polyacrylamide gels and are now extending this technique to softer hydrogels, which are more similar to soft tissue.
- This innovative approach results in hydrogel surfaces that feature exposed nanostructured functional arrays, allowing for more controlled ligand presentation, which is vital for tissue engineering and cellular interactions.
New complex cell junctions in and around the intervertebral discs discovered using autoantibodies from patients affected by endemic pemphigus foliaceus in El Bagre, Colombia, South America.

Article Synopsis
- The study investigates a new variant of endemic pemphigus foliaceus in El Bagre, Colombia, which causes back pain in patients and focuses on the reactivity of their autoantibodies to intervertebral disks (IVDs).
- Researchers used various diagnostic methods, including questionnaires and advanced microscopy, to analyze patient sera and compare them with control sera from healthy individuals in the area.
- Results showed that patients' sera contained antibodies targeting newly identified cell junctions in the IVDs and surrounding structures, suggesting a deeper understanding of spinal diseases and potential implications for treatment.
