We study the coevolution of culture and cooperation by combining the Axelrod model of cultural dissemination with a spatial public goods game, incorporating both noise and social influence. Both participation and cooperation in public goods games are conditional on cultural similarity. We find that a larger "scope of cultural possibilities" in the model leads to the survival of cooperation, when noise is not present, and a higher probability of a multicultural state evolving, for low noise rates. High noise rates, however, lead to both rapid extinction of cooperation and collapse into cultural "anomie," in which stable cultural regions fail to form. These results suggest that cultural diversity can actually be beneficial for the evolution of cooperation, but that cultural information needs to be transmitted accurately in order to maintain both coherent cultural groups and cooperation.

Comparative study of polymeric nanoparticles and traditional agents in dental implant decontamination.

Peri-implant diseases, such as peri-implantitis, affect up to 47% of dental implant recipients, primarily due to biofilm formation. Current decontamination methods vary in efficacy, prompting interest in polymeric nanoparticles (NPs) for their antimicrobial and protein-specific cleaning properties. This study evaluated the efficacy of polymeric nanoparticles (NPs) in decontaminating titanium dental implants by removing proteinaceous pellicle layers and resisting recontamination.

Objectives: Plastics in the environment have moved from an "eye-sore" to a public health threat. Hospitals are one of the biggest users of single-use plastics, and there is growing literature looking at not only plastics in the environment but health care's overall contribution to its growth.
Methods: This study was a retrospective review at a 411-bed level II trauma hospital over 47 months pre and post the last wave of COVID-19 affecting this hospital.
Hook plate fixation and tension band wiring in the treatment of Mayo type II olecranon fractures.

Department of Orthopedic Trauma, Beijing Jishuitan Hospital, Capital Medical University, No. 31 Xinjiekou East Street, Xicheng District, Beijing, 100035, China.
Background: Olecranon fractures account for 8 ∼ 10% of all elbow fractures and usually require surgical intervention. Tension band wiring (TBW) is considered as the standard treatment while it is associated with high re-operation rates.
Objective: This study aims to compare the functional outcomes, complications and re-operations of hook plate fixation (HPF) versus TBW in treating Mayo Type II olecranon fractures.

Background: Both oxidative stress and autoimmune responses play crucial roles in the development of vitiligo. Under oxidative stress, the apoptotic melanocytes expose self-antigens and release high mobility group box 1 (HMGB1), triggering autoimmune activation and recruiting CD8 T cells. This process further leads to the destruction of melanocytes, resulting in the lack of melanin granules.

Department of Orthopedics, Jingzhou Hospital Affiliated to Yangtze University, Jingzhou Hubei, 434020, China.
Background: Although non-surgical and surgical approaches have been developed to repair acute closed Achilles tendon ruptures, the medical community still lacks a definitive consensus on which approach is superior. This study describes a new minimally invasive internal splinting technique combined with knotless anchors for the treatment of 22 patients with acute closed Achilles tendon rupture.
Methods: A retrospective study was conducted involving 22 patients with acute closed Achilles tendon rupture who were treated with a minimally invasive internal splinting technique at Jingzhou Hospital of Yangtze University between January 2022 to October 2023.
