Photobiomodulation therapy in diabetes: Benefits for pain relief, quality of life, and wound healing.

Globally, 537 million people suffer from diabetes mellitus (DM), a condition often associated with sensory disturbances, wound development, and chronic pain, which significantly affects the quality of life and imposes a substantial economic burden. This study evaluated the effects of photobiomodulation (PBM) therapy on nociceptive and sensory changes in diabetic patients to understand pain manifestations and explore PBM's molecular mechanisms on wound healing. Twenty patients with type 2 DM underwent clinical assessments, completed pain and quality of life questionnaires, and had their pain sensitivity evaluated using the quantitative sensory test (QST).

The interplay of edentulism, smoking, microbiota, oral rehabilitation on cytokineprofile and different conditions of hypertension.

Objective: To evaluate the influence of edentulism, smoking, microbiota, and oral rehabilitation on the cytokine profile in healthy and hypertensive edentulous individuals using complete dentures.

Design: This case-control study was divided into four groups: normotensives (control group - NH), controlled hypertensives (case group 1 - CH), unreported hypertensives (case group 2 - UnrH), and uncontrolled hypertensives (case group 3 - UncH). The participants were characterized by sociodemographic data, clinical and behavioral information, and systolic and diastolic blood pressure.

Long-term microbial functional responses in soil contaminated with biofuel/fossil fuel blends triggered by different bioremediation treatments.

The use of biofuel blends with fossil fuels is widespread globally, raising concerns over novel contamination types in environments impacted by these mixtures. This study investigates the microbial functional in soils contaminated by biofuel and fossil fuel blends and subjected to various bioremediation treatments. Using metagenomic analysis, it was compared hydrocarbon degradation functional profiles across areas polluted with ethanol/gasoline and biodiesel/diesel blends.

Balloon pulmonary angioplasty in patients with chronic thromboembolic pulmonary hypertension: short- and long-term results from a cohort in Brazil.

Objective: A significant number of patients with chronic thromboembolic pulmonary hypertension (CTEPH) are not eligible for pulmonary endarterectomy and may be treated with balloon pulmonary angioplasty (BPA). Although BPA programs have recently been developed in Brazil, no results have yet been published. The objective of this study was to assess the clinical and hemodynamic progression of the first patients treated with BPA at our center.

O-substituted Tertiary Amine-chitosans as Promising Nanocarriers for siRNA Delivery.

Introduction: The clinical translation of chitosan-based formulations for siRNA delivery has been partially limited by their poor stability/solubility at physiological conditions, although they have good biocompatibility and cost-effectiveness.

Method: In this study, the chitosan was O-substituted with diisopropylethylamine (DIPEA) groups, which improved its solubility at pH 7.4 by increasing the degree of ionization and enhanced the ability of chitosan to load siRNA at very low amine/phosphate (N/P) ratios.
