Introduction: and importance: Choriocarcinoma is a highly malignant epithelial tumor with often distant metastasis. The clinical presentation of choriocarcinoma depends upon extend of disease and location of metastasis.
Case Presentation: A 35-year-old multiparous woman was presented with severe pelvic pain, fatigue and cough.
On March 11th 2020, the coronavirus outbreak was declared a pandemic by the WHO. One of the groups that is considered high risk in this pandemic are cancer patients as they are treated with a variety of immune system suppressor treatment modalities and this puts them in a great risk for infectious disease (including COVID-19). Therefore, cancer patients require higher level measures for preventing and treating infectious diseases.

Background: Nowadays, image de-noising plays a very important role in medical analysis applications and pre-processing step. Many filters were designed for image processing, assuming a specific noise distribution, so the images which are acquired by different medical imaging modalities must be out of the noise.
Objectives: This study has focused on the sequence filters which are selected by a hybrid genetic algorithm and particle swarm optimization.
Background & Objective: Gliomas are the most common type of primary intracranial tumors in adults. The expression of estrogen receptors varies in different grades of glial tumors, and some studies have suggested that this expression might have a prognostic value. It seems that estrogen receptor expression negatively correlates with the histological grade of gliomas.

Materials And Methods: Twenty-five patients with biopsy-proved diagnosis of glioblastoma participated in this study. T, T-FLAIR images and diffusion tensor imaging (DTI) were acquired 1 week before radiotherapy.
