FeCrNi medium entropy alloys as potential shielding materials for nuclear applications.

Metallic alloys of different compositions are basic structures for building different types of nuclear reactors. This study evaluates the nuclear properties for three medium entropy alloys against incident neutrons and gamma radiation. The alloys had different chemical compositions prepared by powder technology and were compared with two stainless steel alloys for use in constructing different parts of nuclear power plant units.

Variations induced by body weight and background lesion normalization in standardized uptake value estimated by F18-FDG PET/CT.

Aim: This work aims to study the impact of different SUV variants in terms of mean and maximum measures as well as various normalization methods with respect to body weight, body mass index, body surface area, and lean body mass in patients with lymphoma.

Methods: Sixty-nine patients (34 male-35 female) were retrospectively selected. All patients had undergone F18-FDG PET/CT using the standard imaging protocol.

Quantifying inter- and intra-fraction variations of breast cancer radiotherapy with skin dose measurements.

. The aim of the current study was to compare between the deep inspiration breath-hold (DIBH) technique and free-breathing (FB) method in the treatment delivery uncertainty of breast cancer radiotherapy using skin dose measurements..

The necessity of using deep inspiration breath-hold in the radiotherapy of left breast cancer patients who undergo the UK FAST trial.

Aim: The purpose of the current study was to compare between deep inspiration breath-hold (DIBH) and free-breathing (FB) method in the setup reproducibility and to perform a dosimetric comparison between both methods in left-sided breast cancer patients who undergo the UK FAST trial.

Materials And Methods: The online matching correction data were retrospectively collected for 50 patients treated with the FAST trial. They were equally divided into DIBH and FB groups to compare between both methods in the setup reproducibility and create the appropriate planning target volume (PTV) margin.

Assessment of DNA damage in Ehlrich carcinoma after treatment with doxorubicin encapsulated in nanoscales thermosensitive liposomes in combination with localized hyperthermia.

Nanoscales thermosensitive liposomes (TSL) composed of synthetic lipids (dipalmitoylphosphatidylcholine, and distearoylphosphatidylcholine), were used for doxorubicin encapsulation with 70% encapsulated efficiency. The liposomes were characterized by dynamic light scattering, transmission electron microscopy and turbidity method. Additionally, the liposomes exhibited a significant release of doxorubicin (Dox) by 60% within 5 min at 42°C.

Nuclear fragmentation of clinical silicon beam.

Heavy ions used for biomedical studies fragment when they pass through matter. It is known that different fragments cause different types of biological damage. In this paper, results pertaining to different kinds of secondary fragments produced by a 28Si beam at 463 MeV/nucleon in its interaction with nuclear emulsion are presented.
