-Derived β-Glucan Capsules as a Delivery System for DNA Vaccines.

Background/objectives: DNA vaccines are rapidly produced and adaptable to different pathogens, but they face considerable challenges regarding stability and delivery to the cellular target. Thus, effective delivery methods are essential for the success of these vaccines. Here, we evaluated the efficacy of capsules derived from the cell wall of the yeast as a delivery system for DNA vaccines.

Patterning Functional Proteins in Ultrabithorax-Based Materials.

The ability to add bioactivities, such as cell signaling or ligand recognition, to biomaterials has generated the potential to include multiple bioactivities into a single material. In some cases, it is desirable to localize these activities to different areas of the biomaterial, creating functional patterns. While photolithography and 3D printing have been effective techniques for patterning functions in many materials, patterning remains a challenge in materials composed of protein, in part due to how these materials are artificially assembled.

Aquatic animal health: history, present and future.

Aquaculture stands as the fastest-growing food fish sector, expected to satisfy global demand for aquatic products. However, its expansion has led to disease emergence, adversely affecting both production and biodiversity. In response, since the mid-1990s the World Organisation for Animal Health (WOAH) has developed initiatives, notably the Aquatic Animal Health Code and the Manual of Diagnostic Tests for Aquatic Animals, aimed at harmonising health standards for international trade in aquatic animals.

Characterizing Drug use Typologies and Their Association with Sexual Risk Behaviors: A Latent Class Analysis Among Men who have Sex with Men in Mexico.

Introduction: Drug use behaviors are closely associated with increased risk for HIV and other STIs among men who have sex with men (MSM) globally. Less is known about the drug use characteristics and their association with HIV/STI risk among MSM in Mexico, who have 13 times higher risk of acquiring HIV than the general population. We characterized distinct classes of drug use behaviors among a nationwide sample of MSM in Mexico and tested their associations with HIV risk behaviors.
