() is a Gram-positive bacterium that causes infections ranging from mild superficial cases to more severe, potentially fatal conditions. Many photosensitisers used in photodynamic therapy are more effective against superficial infections due to limitations in treating deeper tissue infections. Recently, attention to this bacterium has increased due to the emergence of multidrug-resistant strains, which complicate antibiotic treatment.

Article Synopsis
- Lung transplantation is often necessary for severe lung diseases, but the success rates are low, making lung bioengineering a potential alternative using decellularized lung extracellular matrix (ECM).
- The study focused on improving lung recellularization by seeding decellularized lungs with mesenchymal stem cells and applying photobiomodulation therapy (PBMT) at two different wavelengths (660 nm for recellularization and 880 nm for sterilization).
- Results showed that PBMT helped maintain important structural components of the lungs and modulated pro-inflammatory cytokines, indicating its potential to enhance therapeutic strategies in lung bioengineering.

Article Synopsis
- - Chronic respiratory diseases can lead to irreversible lung damage, making lung transplantation necessary, and organ engineering with stem cells shows promise for generating new organs.
- - This study systematically reviewed literature on decellularised lungs' extracellular matrix (ECM) conditions after various sterilisation processes, following PRISMA guidelines and analyzing five positive-result articles.
- - The findings indicate that all sterilisation methods, whether physical or chemical, negatively impact the ECM, and no ideal sterilisation protocol was identified for effective pulmonary scaffold preparation in tissue or organ engineering.
Objective: The aim of the present study was to compare the effect of low-level laser therapy (LLLT) and low-intensity pulsed ultrasound (LIPUS) on the cytoskeleton and endoplasmic reticulum of L929 cells. Thermal and non-thermal physical mechanisms such as LLLT and LIPUS induce clinically significant responses in cells, tissues, and organs.
Materials And Methods: L929 fibroblast cell cultures were irradiated with LLLT and subjected to LIPUS.
Objective: The objective of this study was to compare the effect of low-level laser therapy (LLLT) and low-intensity pulsed ultrasound (LIPUS) on fibroblast cell culture. Several methods, including ultrasound treatment and LLLT, are being used to facilitate tissue repair and healing processes.
Materials And Methods: L929 fibroblast cell cultures were irradiated with low-level laser energy and LIPUS.
The objective of the study was to establish the prevalence rate of depression among the elderly population (those 60 and older) who frequent community centers. From February to July of 2001, a cross-sectional survey was conducted with elderly people from community centers in Taguatinga, Brasilia, FD (Federal District). The sample included 118 elderly people, distributed in five-year age brackets, who responded to a simplified version of the Yesavage Geriatric Depression Scale with 15 questions.
