Published: December 2018

In this paper we'll shed some light on well-known physical parameters to introduce them as new tools, biophysical markers, for diagnosis and prognosis of the molecular, cellular, tissue and organ biosystems such as Haemoglobin representing the macromolecules' category. Where the data reveal a lot of information about the effect of radiation dose rate on the macromolecule that are not discovered by conventional ways. Also, data put forward the dielectric and thermodynamical parameters and classify them as premiers and superiors for the detection of any disturbance that occurs in the electrical homogeneity of the macromolecule. The interesting results showed an inverse response of the Hb molecule toward higher and lower dose rates for all tested parameters, Static permittivity and change in the following thermodynamical state functions Helmholtz free energy, internal energy and entropy.

Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.

Photon mini-GRID therapy for preoperative breast cancer tumor treatment: A treatment plan study.

Background: Breast cancer is the leading cause of female cancer mortality worldwide, accounting for 1 in 6 cancer deaths. Surgery, radiation, and systemic therapy are the three pillars of breast cancer treatment, with several strategies developed to combine them. The association of preoperative radiotherapy with immunotherapy may improve breast cancer tumor control by exploiting the tumor radio-induced immune priming.

MR imaging of proton beam-induced oxygen depletion.

Background: Previous studies have shown that in-beam magnetic resonance imaging (MRI) can be used to visualize a proton beam during the irradiation of liquid-filled phantoms. The beam energy- and current-dependent local image contrast observed in water was identified to be predominantly caused by beam-induced buoyant convection and associated flow effects. Besides this flow dependency, the MR signal change was found to be characterized by a change in the relaxation time of water, hinting at a radiochemical contribution, which was hypothesized to lie in oxygen depletion-evoked relaxation time lengthening.

Effects of UVC doses on the removal of antimicrobial resistance elements from secondary treated sewage.

Programa de Pós-Graduação Em Saneamento, Meio Ambiente E Recursos Hídricos, Departamento de Engenharia Sanitária E Ambiental, Universidade Federal de Minas Gerais, Av. Antonio Carlos 6627, Belo Horizonte, MG, 31270-901, Brazil.

Wastewater treatment plants (WWTPs) currently face major challenges toward the removal of microcontaminants and/or microbial matrices and consequently play an important role in the potential dissemination of biological resistance in freshwater. The ultraviolet (UV) system is a tertiary treatment strategy increasingly applied worldwide, although many studies have shown that disinfected effluent can still contain antibiotic-resistant bacteria and resistance genes. Therefore, to better understand the effects of UV radiation doses on the removal of all resistance elements (antibiotics, antibiotic-resistant bacteria, and antibiotic resistance genes), the present study was designed using a pilot-scale photoreactor.

Goal of the present study was to develop and build a phantom that replicates the air gaps under a gel bolus and to estimate the surface dose (D) under normal incidence with a 6 MV photon beam. For this, an acrylic phantom with 10 plates, each including five open slots (one in the centre and four off axis) with a size of 2 cm × 2 cm at depths of 0.54 cm, 0.
