However, the administration of 1 mM of melatonin 1 h before irradiation significantly reduced the cell proliferation. Nonetheless, there was no significant difference between this treatment group and 1 mM melatonin group. Moreover, the administration of melatonin in combination with irradiation did not show any significant effects on radiation-induced apoptosis.

The current study results indicated that the treatment of A549 cells with melatonin could suppress cell proliferation, whereas it did not mediate the induction of apoptosis.

Melanoma causes the highest number of skin cancer-related deaths worldwide. New treatment methods are essential for the management of this life-threatening disease.

In this study, we investigated the efficacy of a standardized Cannabis sativa extract alone or in combination with single radiation dose (6 Gy) in B16F10 mouse melanoma cells in an extract dose-dependent manner.

C. sativa extract at three concentrations (25, 12.5, and 6.25 μg/mL) alone for 72 h or in combination with radiation (24 h incubation after the extract treatment + 48 h incubation after exposure to radiation) were evaluated for cell viability of melanoma cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Cells were also treated with 6.25 μg/mL extract alone for 72 h before analyzing C. TASIN-30 sativa-induced cell death by flow cytometry.

Administration of the extract alone or alongside radiation substantially inhibited melanoma cell viability and proliferation in the extract dose response-dependent manner. The anoma.
T1-contrast and T2-flair images of magnetic resonance imaging (MRI) are commonly fused with computed tomography (CT) and used for delineation of postoperative residual tumor and bed after surgery in patients with glioblastoma multiforme (GBM). Our prospective study was aimed to see the feasibility of incorporating perfusion MRI in delineation of brain tumor for radiotherapy planning and its implication on treatment volumes.

Twenty-four patients with histopathologically proven GBM were included in the study. All patients underwent radiotherapy planning with a contrast CT scan. In addition to radiotherapy (RT) planning protocol, T1-perfusion MRI was also done in all patients in the same sitting. Perfusion imaging was processed on the in-house-developed JAVA-based software. The images of CT and MRI were sent to the iPlan planning system (Brainlab AG, GmbH) using a Digital Imaging and Communications in Medicine - Radiation Therapy (DICOM-RT) protocol. A structure of gross tumor volume (GTV)-perfusion (GTV-P) future studies.
Meningiomas are common slow-growing primary intracranial neoplasms attached to the dura mater and are composed of neoplastic meningothelial cells. Increased incidence of meningiomas in women with an increased tumor growth during pregnancy and a possible association with breast cancer suggested that female sex hormones have been involved in the growth of meningiomas. Antihormonal-targeted therapy would be beneficial in such patients.

The aim of this study is to correlate the expression of estrogen receptor (ER) and progesterone receptor (PR) in meningiomas with gender, location, histological subtypes, and grade.

This is a 3½-year prospective and retrospective study of intracranial and intraspinal meningiomas. Clinical details of all the patients were noted from the computerized hospital information system. Immunohistochemistry for ER and PR was performed. Statistical analysis was performed using Chi-square test.

During the study period, there were 80 Grade I, 18 Grade II, and 2 Grade III meningiomas categorized as per the World Health Organization 2007 classification. The female-to-male ratio was 1.91 and the mean age was 47.8 years. ER was expressed in 2% of meningiomas. PR was expressed in 67.5% of Grade I and 66.6% of Grade II and none of Grade III meningiomas. Brain-invasive meningiomas showed 54.5% PR immunopositivity and negative for ER.

ER and PR were expressed in 2% and 66% of meningiomas, respectively. Statistically significant relationship was not found between the positivity of PR in females and males of Grade I and Grade II/III meningiomas, intracranial and spinal tumors, Grade I and Grade II/III cases, and various histological subtypes of meningiomas.

Isocitrate dehydrogenase-1 (IDH1) mutation is now an established early event in gliomagenesis. The ability to detect this mutation by several techniques including immunohistochemistry makes it a significant marker for diagnosing and prognosticating gliomas. This study was done to assess the expression of mutant IDH1 in different grades of gliomas and evaluate its utility in differentiating reactive gliosis from glioma and defining surgical margins of these tumors in the operative specimens.

A total of fifty cases including equal number of Grade I, II, III, and IV gliomas and gliosis were included in the study. Formalin-fixed, paraffin-embedded tissue sections from these lesions were immunostained with IDH1 and Ki-67 antibody, and percentage of tumor cells that stained positive with these markers was assessed.

Grades II, III, and IV showed consistent immunopositivity for IDH1. No immunostaining was noted in Grade I glioma and gliosis. Mean Ki-67 labeling index correlated with grades of gliomas with low activity in Grade I and high activity in Grade IV. Individual tumor cells infiltrating into adjacent normal brain parenchyma also stained positive with IDH1 antibody.

Immunostaining for IDH1 mutation can be utilized as a reliable marker in the precise diagnosis of diffuse gliomas and also in objective assessment of surgical margins to differentiate gliomas from gliosis.
