Optimal Timing of Photobiomodulation Therapy for Retinal Diseases: Leveraging Circadian Mitochondrial Rhythms.

Age-related retinal degeneration is associated with mitochondrial dysfunction. Emerging evidence suggests that photobiomodulation therapy (PBMT) using near-infrared light may improve mitochondrial function and visual performance, but its efficacy is critically time-dependent. This article explores how daily biological rhythms and mitochondrial function interact, focusing on the potential of timed PMBT for age-related eye diseases.

The impact of aging on neutrophil functions and the contribution to periodontitis.

The increasing aging population and aging-associated diseases have become a global issue for decades. People over 65 show an increased prevalence and greater severity of periodontitis, which poses threats to overall health. Studies have demonstrated a significant association between aging and the dysfunction of neutrophils, critical cells in the early stages of periodontitis, and their crosstalk with macrophages and T and B lymphocytes to establish the periodontal lesion.

A New Heteroleptic Zn(II) Complex with Schiff Bases Sensitizes Triple-Negative Breast Cancer Cells to Doxorubicin and Paclitaxel.

: Triple-negative breast cancer (TNBC) is the most challenging molecular subtype of breast cancer (BC) in clinical practice, associated with a worse prognosis due to limited treatment strategies and its insensitivity to conventional drugs. Zinc is an important trace element for homeostasis, and its Schiff base metal complexes have shown promise in treating advanced tumors. In this study, four new heteroleptic Zn(II) complexes (-) with Schiff bases were synthesized, characterized, and evaluated for their activity in BC cells.

Short-Term Results of Multiwavelength Photobiomodulation in Retinitis Pigmentosa.

Objective: To assess the short-term effects of Multiwavelength Photobiomodulation (LumiThera Valeda Light Delivery System) on retinal functional behavior in patients with retinitis pigmentosa (RP).

Materials And Methods: Twelve RP patients (24 eyes) underwent treatment involving nine photobiomodulation (PBM) sessions using the Valeda system, which emits three distinct wavelengths within the yellow (590 nm; 4 mW/cm2), red (660 nm; 65 mW/cm2), and near-infrared (NIR) (850 nm; 0.6 mW/cm2) spectrum.

[Experience of setting up a state pharmacovigilance committee during the COVID-19 pandemicExperiencia de la puesta en marcha de un comité estatal de farmacovigilancia durante la pandemia de COVID-19].

Objective: To describe the implementation and pioneering work of a vaccine pharmacovigilance committee in the state of São Paulo, Brazil, for the analysis of events supposedly attributable to vaccination or immunization (ESAVI) during the COVID-19 pandemic.

Methods: This is a retrospective, mixed-methods (qualitative and quantitative) case study focusing on the work carried out by the pharmacovigilance committee in the years 2021 and 2022. The minutes of committee meetings were used to describe how the committee operates.
