Combined Antibiotic and Photodynamic Therapies in : From Synergy to Antagonism.

Antibiotics remain the most effective option for combating infections. However, the situation has shifted from ideal to concerning, as bacterial resistance to antibiotics is increasing in both prevalence and strength. : This study explores the synergistic/antagonistic potential of combining antibiotic and photodynamic therapy (PDT) against .

Photodynamic therapy as a potential approach for preventing fungal spread associated with the use of endotracheal tubes.

Fungal infections related to biofilm formation on medical devices, such as endotracheal tubes (ETTs), pose significant health risks, especially during intubation procedures where fungi like Candida spp. can migrate into the lower respiratory tract. This study explores the use of Photodynamic Therapy (PDT) to prevent fungal cell migration from ETT surfaces to lungs, focusing on the role of curcumin as a photosensitizer.

HLA-B*15 Is Associated With SARS-CoV-2 Infection in a Brazilian Population.

Studies have suggested an association between polymorphisms in class I genes of the major histocompatibility complex, specifically the human leukocyte antigen (HLA), and susceptibility to SARS-CoV-2. To explore this, 135 individuals with positive serological tests for SARS-CoV-2 were recruited. All the samples were collected before the advent of vaccines, avoiding immunization effects.

Production of dendritic cell vaccines using different methods with equivalent results: Implications for emerging centers.

Introduction: Dendritic cell (DC) vaccines have demonstrated good efficacy in preventing relapse and in increasing survival of patients affected by a variety of both solid and hematological tumors. Most protocols used to generate these cells involve the automated separation of peripheral blood monocytes from patients. This approach requires specialized equipment, which elevates the cost of this type of therapy, potentially limiting the widespread access to patients.

Selection of plasma donors for the production of anti-SARS-CoV-2 immunoglobulin-based therapies: Strategies for quantitative antibody measurements.

Even after two years of the pandemic, a completely effective treatment against SARS-CoV-2 has not yet been established. Considering this fact and the emergence of successive new viral variants, the development of therapies based on natural polyclonal antibodies recovered from convalescent plasma remains relevant. This study presents a comparison between different methods of screening antibodies in samples of 41 individuals previously diagnosed with COVID-19.
