To investigate whether low-level laser therapy (LLLT), at different times of application (immediate and late) in the region of the parotid glands, has a distance effect on the microarchitecture of the trabecular bone in mandible of rats irradiated by volumetric modular arc therapy (VMAT). Thirty adult Wistar rats were randomly divided into placebo control groups (CG, n = 2), only radiotherapy (RG, n = 2), only LPLT (LG, n = 2), and two other groups using LLLT in the immediate time (24 h) (ILG, n = 12) and late (120 h) (LLG, n = 12) to radiotherapy by VMAT in a single dose of 12 Gy. LLLT with AsGaAl laser (660 nm, 100 mW), a spot size of 0.

Thirty-two adult male Wistar rats were used in this study. Samples were randomly assigned to three groups: control group (CG, n = 8), immediate laser group (24 hours) (ILG, n=12), and late laser group (120 hours) (LLG, n=12).

- - The study aimed to examine anemia's occurrence and severity in patients diagnosed with oral cancer, particularly its relation to tumor cell differentiation, using records from 366 patients at referral centers.
- - Among the patients, 15.7% with oral squamous cell carcinoma (OSCC) had anemia compared to 11.8% with benign lesions, though the association between anemia and OSCC wasn't statistically significant.
- - Normocytic anemia was most common at diagnosis, with moderate to severely low hemoglobin levels linked to OSCC, demonstrating a significant odds ratio of 6.49, although there were gaps in the hematological data.
Evaluation of Aquaporins 1 and 5 Expression in Rat Parotid Glands After Volumetric Modulated Arc Radiotherapy and Use of Low-Level Laser Therapy at Different Times.

Article Synopsis
- The study explored how low-level laser therapy (LLLT) affects the expression of aquaporins (AQPs 1 and 5) in the parotid glands of rats after they received volumetric modulated arc therapy (VMAT) radiation.
- The research involved 30 Wistar rats divided into control and experimental groups, with some receiving LLLT just after radiation and others later, to assess the timing's impact on gene expression.
- Results indicated that LLLT increased AQP expression in the glands, especially when administered alone and even after radiation treatment, suggesting a potential therapeutic benefit for maintaining these proteins post-radiotherapy.
