Incidental Diagnosis of Primary Pleural Liposarcoma in a COVID-19-Positive Patient.

A few cases of primary liposarcoma of pleura have been reported worldwide. We report a young gentleman who was admitted with what was initially thought as coronavirus disease 2019 (COVID-19)-related pulmonary symptoms. His chest CT showed a large pleural effusion causing a mediastinal shift and compressing vital structures.

A Rare Case of a Left Ventricular Pseudoaneurysm With Lateral Wall Rupture.

In this report, we present a case of a 51-year-old male patient with a left ventricular (LV) pseudoaneurysm and a ruptured lateral wall due to a previous myocardial infarction. This patient was referred to the Coronary Care Unit with a past history of acute coronary syndrome of two months. He presented with palpitations and acute pulmonary edema upon admission.

Radiation-inducible radioprotective exopolysaccharides of CV5 from irradiated roots of to decrease free radical damage produced by ionizing radiation.

To assess exopolysaccharides (EPS) of CV5, isolated from irradiated roots of , for their induction by ionizing radiation (IR) and their antioxidant and radioprotective power. Isolated bacteria from the roots of were screened for EPS production. The most EPS-producing bacterium was selected and the response surface methodology (RSM) was applied to elucidate the IR dose effects on EPS production.

Polyphenolic extracts from the xerophyte Rhamnus lycioides as a radiation biodosimeter.

The majority of dosimeters currently in use are synthetic and very expensive. Therefore, the study of the dosimetric characteristics of polyphenolic extracts of xerophytes is useful because drought stress causes an increase in the production of these cheap and natural compounds containing benzene rings. Here, the polyphenolic compounds were extracted from Rhamnus lycioides which was collected from Bou-Hedma National Park in Tunisia and identified using liquid chromatography-mass spectrometry (LC-MS).
