Black Goji Berry Extract as a Natural Photosensitizer for Photodynamic Inactivation of Microbial Strains: A Promising Approach

Journal of Medical Microbiology and Infectious Diseases, 2023
Introduction: Antimicrobial resistance is a critical public health concern directly contributing to many deaths globally. Unearthing new protocols to tackle pathogenic microorganisms is vital. Photodynamic inactivation (PDI) is an efficient method for

Photodynamic Inactivation of the Vacuolating Virus, SV40

Experimental Biology and Medicine, 1962
SummaryThe vacuolating virus, SV40, is inactivated by visible light in the presence of toluidine blue (6 μg/ml) at quantum densities which have previously been shown to have almost no effect upon infectivity of poliovirus. The possible application of this process as a means of differential inactivation of SV40 in suspensions of live poliovirus was ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Photodynamic inactivation of oropharyngeal Candida strains

Phytomedicine, 2014
Oropharyngeal candidiasis (OPC) is an infection frequent in immunocompromised patients. Photodynamic therapy is an alternative to conventional treatments, based on the utilization of compounds that inhibit or kill microorganisms only under the effect of light, process known as Photodynamic Inactivation (PDI).

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

BMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

Tackling cancer stemness with nanotechnology in the era of precision medicine

BMEMat, EarlyView.
Precise customization of nanoparticles (NPs) enables active targeting of cancer stem cells (CSCs), thereby improving drug delivery and therapeutic efficacy. NP‐based probing enhances CSC detection through imaging and liquid biopsy, whereas diverse therapeutic payloads improve therapeutic outcomes.

Inativação fotodinâmica de microrganismos Photodynamic inactivation of microorganisms

Química Nova, 2007
Photodynamic Therapy uses photosensitive dyes and visible light that, combined in the presence of oxygen, produce cytotoxic species that cause tumor death. Microorganisms such as bacteria, fungi, yeasts and viruses (including HIV) can also be inactivated

From pathogen to “living drug factory” innovative strategies and clinical translation of bacteria as programmable intelligent vectors for cancer therapy

BMEMat, EarlyView.
Engineered bacteria serve as smart, living therapeutics that target tumors, deliver drugs, and remodel immunosuppressive microenvironments. This review highlights their potential to potentiate immunotherapy, radiotherapy, and chemotherapy, offering a promising paradigm for precise and synergistic cancer treatment. Abstract The dynamic interplay between
