Article Abstract

is a pathogenic fungus associated with high-mortality infections and forms resilient biofilms on various surfaces. In this study, we introduced a novel antifungal strategy against by integrating an AI-powered protein design tool, ProteinMPNN, with classical molecular dynamics (MD) simulations to design artificial proteins from a miniprotein library. This combined approach accelerated and enhanced the design process, enabling the rapid development of effective miniprotein inhibitors specifically targeting biofilm formation. The miniproteins developed in this study exhibited potent inhibitory effects on biofilms, representing a significant advancement in antifungal therapy. Notably, the combined application of these miniproteins enhanced suppression of biofilm formation. These findings highlight not only the strong therapeutic potential of these designed miniproteins but also the power of combining AI-driven protein design with MD simulations to advance biomedical research.

Biofilms-microbial communities encased in a self-produced extracellular matrix-pose a significant challenge in clinical settings due to their association with chronic infections and antibiotic resistance. Their formation in the human body is governed by a complex interplay of biological and environmental factors, including the biochemical composition of bodily fluids, fluid dynamics, and cell-cell and cell-surface interactions. Improving therapeutic strategies requires a deeper understanding of how host-specific conditions shape biofilm development.

Microswimmer locomotion in non-Newtonian fluids is crucial for biological processes, including infection, fertilization and biofilm formation. The behaviour of microswimmers in these media is an area with many conflicting results, with swimmers displaying varying responses depending on their morphology, actuation and the complex properties of the surrounding fluid. Using a hybrid computational approach, we numerically investigate the effect of shear-thinning rheology and viscoelasticity on a simple conceptual microswimmer consisting of three linked spheres.

Background: Malassezia genus includes lipodependent commensal yeasts of humans and animals' skin and mucous membranes. It can cause dermatological pathologies, and azoles are mainly used for treatment. However, in vitro susceptibility testing has shown decreased sensitivity to these antifungals.

The mechanisms by which vaginal microbiota shape spontaneous preterm birth (sPTB) risk remain poorly defined. Using electronic clinical records data from 74,913 maternities in conjunction with metaxanomic (n = 596) and immune profiling (n = 314) data, we show that the B blood group phenotype associates with increased risk of sPTB and adverse vaginal microbiota composition. The O blood group associates with sPTB in women who have a combination of a previous history of sPTB, an adverse vaginal microbial composition and pro-inflammatory cervicovaginal milieu.

Purpose: This study aimed to evaluate the performance of 3D-printed denture base resins (DBRs) compared with conventionally printed DBRs, examine their biofilm formation and physical properties, and determine the viability of 3D-printed DBRs as a superior alternative in removable prosthodontics.

Methods: The DBR samples were fabricated using traditional packing (TRA), milling (MIL), and 3D printing (3DP) methods. All samples were serially polished with an abrasive paper.
