Twenty-four Sprague-Dawley rats were divided into three groups: Rats in Group 1 (control group). Group 2 (X-ray irradiation) and group 3 (X-ray irradiation + Dexmedetomidine) were given a total of 10 Gy external beam total body irradiation.

Comparison of effects of dexmedetomidine and amifostine against X-ray radiation-induced parotid damage.

Radiotherapy can be employed as a therapeutic modality alone in the early stages of cancer and is used together with other treatments such as surgery and chemotherapy in more advanced stages. However, exposure to ionizing radiation in association with radiotherapy affects several organs in the head and neck and can give rise to early and late side effects. Exposure to ionizing radiation used in radiotherapy is known to cause cell damage by leading to oxygen stress through the production of free oxygen radicals (such as superoxide radicals, hydroxyl radical, hydrogen peroxide, and singlet oxygen), depending on the total radiation dosage, the fractionation rate, radiosensitivity, and linear energy transfer.

Can Dexmedetomidine Be Effective in the Protection of Radiotherapy-Induced Brain Damage in the Rat?

Approximately 7 million people are reported to be undergoing radiotherapy (RT) at any one time in the world. However, it is still not possible to prevent damage to secondary organs that are off-target. This study, therefore, investigated the potential adverse effects of RT on the brain, using cognitive, histopathological, and biochemical methods, and the counteractive effect of the α2-adrenergic receptor agonist dexmedetomidine.

An urban legend: Malignant transformation caused by radiotherapy in patients with presacral ganglioneuroma. The necessity and first-time administration of radiotherapy. Case report and literature review.

Ganglioneuromas (GNs) are well-differentiated, rare benign tumors of neural crest origin and are, for the most part, considered to be the benign equivalent of neuroblastomas. There are very few cases of GN reported to be at presacral location in the literature. The standard form of treatment is the total surgical excision.

F-FDG PET/CT Imaging of Metastatic Testicular Choriocarcinoma Mimicking Gastric Cancer which Initial Symptom is Melena.

Gastric metastasis of choriocarcinoma is rarely reported in the literature. This case report presents the case of multiple metastatic testicular choriocarcinoma mimicking gastric cancer, with melena as the initial symptom. In this case, fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) showed that the testis was the primary focus.

Method to prevent the target volume from escaping out of the field in breast irradiation: Forming a "fall-off margin".

Objectives: We aimed to obtain data that would enable the selection of the appropriate radiotherapy technique for whole breast irradiation (WBI) based on patients' physical characteristics and to evaluate the benefit of the new fall-off (FO) margin technique.

Materials And Methods: Ten patients with left-sided breast-conserving surgery, treated for breast carcinoma between August 2016 and September 2017, were included. The FO margin was created in five different plans of which two were formed by expanding the target volume out of the skin.

Interesting different survival status of musicians with malignant cerebral tumors.

The education of a musician may have an effect on the neuronal functions and organization of the brain, promote brain plasticity, resulting in functional and structural changes. A variety of malign cerebral tumors have affected the musician, instrumentalist or singer, at some time during their lives. No comprehensive investigation for musicians with malignant tumors has been performed yet.

Pelvic Radiation-Induced Testicular Damage: An Experimental Study at 1 Gray.

Therapeutic radiation of the pelvic region has been shown to cause damage to testicular germ cells. In this study we aimed to evaluate the effects of a low therapeutic dose of 1 Gy on the induction of cellular and histological damage in early-stage testicular germ cells and the impact of this radiation on offspring sex ratio. Unirradiated and irradiated male rats were mated with unirradiated female rats.

Colorful Screams of Silent Emotions: A Study with Oncological Patients.

Background: Art, as a product of human behavior, is the expression of emotions from inner states and may provide catharsis, purification, and release. Several branches of art, most notably music, dance, and painting, can be used for treatment purposes, especially in the case of psychological disorders. Cancer, which is defined as uncontrolled cell growth, has been an important health issue throughout history, but the recent increase in its frequency has made it one of the most significant public health problems.

The purpose of this study was therefore to investigate the effects of radiotherapy on the kidney and the potential use of agents such as N-acetylcysteine (NAC) in developing a future therapeutic protocol for radiation-induced nephrotoxicity at the histopathological and biochemical levels. Our study consisted of three groups: control (oral saline solution only; group 1), irradiation (IR; group 2), and NAC + IR (group 3). The irradiation groups received a single dose of whole-body 6-Gy x-irradiation.

Radioprotective effect of endogenous melatonin secretion associated with the circadian rhythm in irradiated rats.

We investigated the radioprotective effect of endogenous melatonin release at different times associated with the circadian rhythm on head and neck radiotherapy. Two groups of animals were subjected daily to 8 Gy single fraction radiotherapy in the head and neck region from 5:00 to 6:00 (the morning group) or from 19:00 to 20:00 (the evening group). Corresponding untreated groups served as controls.

Protective Effect of Whortleberry Extract on Salivary Gland Damage Induced by Neck Irradiation in Rats.

Radiotherapy is a method of treatment used on malignant head and neck tumors; however, it may lead to adverse effects by influencing other tissues because its effects are not specific to tumor tissues. These adverse effects limit the effectiveness of the treatment and sometimes lead to termination of the treatment. This study aims to histopathologically and biochemically investigate the protective effect of whortleberry against the cellular degeneration and oxidative stress that take place in salivary glands due to radiotherapy.

The effects of N-acetylcysteine on radiotherapy-induced small intestinal damage in rats.

Some six million cancer patients currently receive radiotherapy. Radiotherapy eliminates cancer cells by accelerating their death. However, radiotherapy is not selective, and it therefore harms healthy tissues around cancerous tissue.

An investigation of the effects of N-acetylcysteine on radiotherapy-induced testicular injury in rats.

According to data issued by the International Agency for Research on Cancer in 2012, the estimated number of new cases of all types of cancer worldwide was estimated to exceed 10 million, and 6 million of whom receive radiotherapy. Radiotherapy is the treatment of cancer using ionizing radiation. Our study investigated the effects of x-radiation resulting from radiotherapy (RT) on the testis at the molecular level, and prospectively considered the potential protective characteristics of antioxidants against testicular damage resulting from x-radiation.
