in the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. we have also investigated the structure of neutron stars. according to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.

Bladder cancer has been observed in patients after permanent iodine-125 brachytherapy （hereafter referred to as brachytherapy） for prostate cancer. We investigated secondary bladder brachytherapy. From January 2005 March 2021, a total of 1,478 underwent localized at Showa University Hospital and Koto Toyosu Hospital. A standardized incidence rate was calculated from the compared with national r...

Background: Prompt gamma neutron activation analysis (PGNAA) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. Also it is a valuable diagnostic tool for total body elemental measurements. 252Cf and 241Am-Be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...

background: the aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or pmma), a150 plastic and te- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. materials and methods: thermal neutron fluence, photon dose and epithermal neut...

This review summarizes the current understanding of the feasibility of functional imaging for brachytherapy. In following subsections the role of ultrasound, power doppler imaging, positron emission tomography, magnetic resonance imaging, dynamic dose calculation and targeted brachytherapy is analyzed. The combination of functional imaging with the new tools for intraoperative dose calculation ...

Radiotherapy is an integral component of management of high-grade soft tissue sarcomas. Interstitial brachytherapy is used to deliver a boost or radical dose with several advantages over external beam radiotherapy. There has always been a concern to use brachytherapy with flap reconstruction of skin defects after wide excision. We preset our initial experience with interstitial brachytherapy in...

Both primary and recurrent squamous cell carcinoma of the head and neck are classic indications for brachytherapy. A high rate of local tumor control at the cost of limited morbidity can be achieved with brachytherapy through good patient selection, meticulous source implantation and careful treatment planning. However, no randomized trials have been performed, and there is scant evidence in th...

PURPOSE To evaluate gold marker displacement due to needle insertion during HDR-brachytherapy for therapy of prostate cancer. PATIENTS AND METHODS 18 patients entered into this prospective evaluation. Three gold markers were implanted into the prostate during the first HDR-brachytherapy procedure after the irradiation was administered. Three days after marker implantation all patients had a C...

BACKGROUND This study assessed the survival outcomes and recurrent patterns in pelvic node-positive IB1-IIA2 cervical cancer patients treated with postoperative external beam irradiation with or without vaginal brachytherapy. METHODS The records of 1149 cervical cancer patients received radical surgery between February 2008 and March 2010 were retrospectively reviewed. 126 stages IB1-IIA2 pat...
