Intravitreal melatonin for the prevention of radiation retinopathy: a step beyond bevacizumab.

Purpose: Intravitreal bevacizumab has been utilized to mitigate radiation retinopathy, yet the potential role of intravitreal melatonin for its prevention remains unexplored. This study aims to evaluate and compare the efficacy of intravitreal melatonin and bevacizumab in preventing radiation retinopathy in an experimental animal model.

Materials And Methods: Twelve healthy male New Zealand white rabbits ( = 24 eyes) received a single 3000 cGy irradiation dose in both eyes.

Effect of Sertraline and Vortioxetine on Stress-Induced Brain Injury in Rats: Biochemical and Histopathological Evaluations.

Objectives: Our aim was to evaluate the comparative effects of sertraline and vortioxetine against stress-induced brain injury in rats.

Methods: The rats were assigned to a nonstress group (NSG), stress-treated control (StC), sertraline + stress (SSt), and vortioxetine + stress (VSt) groups. Sertraline and vortioxetine (10 mg/kg) were given orally by gavage to the SSt and VSt groups.

The role of radiotherapy in intracranial hemangiopericytoma/solitary fibrous tumors : A Turkish Society for Radiation Oncology Central Nervous System Tumors Group Study (TROD 07-008).

Objective: Intracranial hemangiopericytomas (HPC) are rare tumors. Radiotherapy (RT) is frequently performed after surgery, depending on tumor size, location, and the type of resection. Moreover, RT is preferred as an effective treatment for local recurrence and metastasis.

The Role of Radiotherapy in Indolent Ocular Adnexal and Orbital Lymphomas.

Background: This study evaluates the oncological outcomes and toxicities of indolent ocular adnexal and orbital lymphomas (OOLs) treated with radiotherapy (RT) ± systemic therapy.

Methods: A retrospective analysis of 44 patients with indolent OOLs treated with RT was conducted.

Results: Most patients (87%) had early-stage disease.

Analysis of patients with parotid recurrence after parotid-sparing IMRT for nasopharyngeal carcinoma: case series and review of the literature.

Purpose: Intensity-modulated radiotherapy (IMRT) is the standard treatment approach for nasopharyngeal cancer (NPC). IMRT enables effective sparing of the parotid glands and reduces the risk of xerostomia, a common complication of head and neck irradiation. Nevertheless, it is essential to determine whether the parotid-sparing IMRT (ps-IMRT) technique yields increased intra-/periparotid recurrence rates, which constitutes the main purpose of this study.
