Less cytotoxic phthalocyanine derivative promotes in vitro wound healing compared to chlorhexidine.

The use of adjunct chemical substances in the early postoperative period of periodontal surgical procedures is recommended due to the potential risk of trauma in the operated area. Chlorhexidine digluconate mouthwash is widely used but can cause adverse effects. Phthalocyanine derivatives are being studied as an alternative, demonstrating good antimicrobial activity, especially in the self-activated form, which does not require additional light or chemicals.

Background: COVID-19 was first identified in Wuhan, China, in December 2019, where it spread over a wide geographic area until it reached the status of a pandemic in 2020. We postulated that patients who were diagnosed with incidental COVID-19, and underwent surgery, did not have a worse outcome due to the COVID-19 virus compared to their counterparts who did not have the virus.
Methods: This retrospective study included surgical patients (COVID-19 incidentals and COVID-19 negatives) who were admitted to the surgical intensive care unit (SICU) at Tygerberg Academic Hospital between 1 May 2020 and 31 December 2021.
Comparative study of polymeric nanoparticles and traditional agents in dental implant decontamination.

Faculty of Dentistry, Department of Periodontics, Complutense University of Madrid, Madrid, Spain.
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.

Introduction: Circulating tumor cells (CTCs) have attracted significant interest as a biomarker for cancer diagnosis. In this study, we judiciously constructed a recombinant MUC1-dependent adenovirus (rAdF35-MUC1) that can selectively replicate and overexpress copepod super green fluorescent proteins (copGFP) in MUC1-positive tumor cells to investigate its role in the detection of CTCs.
Methods: We conducted a comparative study between rAdF35-MUC1 and the existing hTERT-dependent adenovirus (rAdF35-hTERT).
Evaluation of vaccine perceptions in Israel's Elderly: A Comparative study of COVID-19 and influenza vaccination attitudes.

Clinical Microbiology Laboratory, Tzafon Medical Center, Poriya, Israel, affiliated with Azrieli Faculty of Medicine, Bar Ilan University, Safed, Israel.
Purpose: This study aimed to evaluate the attitudes of Israeli elderly population towards COVID-19 and influenza vaccines, and to assess factors contributing to these attitudes.
Methods: Four-hundred and one participants exhibiting symptoms consistent with COVID-19 or influenza were enrolled and filled out a questionnaire. A second questionnaire was filled out for hospitalized patients at discharge.
