Addressing the post-irradiation hypothalamic-pituitary endocrine abnormalities of brain tumors in pediatric patients
(2017)Purpose: Hypothalamic-pituitary axis is susceptible to radiotherapy, causing endocrine disorders to childhood cancer survivors. We conducted a systematic review in order to assess the radiation-induced toxicity that leads ... -
Breast radiotherapy and early adverse cardiac effects. The role of serum biomarkers and strain echocardiography
(2019)Breast cancer radiotherapy has a clear benefit for both long-term survival and local recurrence rate. However, there is still much concern about the early radiation-induced heart toxicity. This article aimed to clarify the ... -
Bridging plant and human radiation response and DNA repair through an in silico approach
(2017)The mechanisms of response to radiation exposure are conserved in plants and animals. The DNA damage response (DDR) pathways are the predominant molecular pathways activated upon exposure to radiation, both in plants and ... -
Clinical value of significance of hypoxia inducible factor-1α, glucose transporter-1 and carbonic anhydrase IX in rectal cancer after preoperative chemoradiotherapy
(2019)Purpose: The standard treatment of rectal cancer is surgery along with preoperative radiotherapy, administered alone or in combination with chemotherapy. Preoperative chemoradiotherapy (preCRT) is widely used as it allows ... -
Direct exposure of the head to solar heat radiation impairs motor-cognitive performance
(2020)Health and performance impairments provoked by thermal stress are societal challenges geographically spreading and intensifying with global warming. Yet, science may be underestimating the true impact, since no study has ... -
Flash proton radiotherapy spares normal epithelial and mesenchymal tissues while preserving sarcoma response
(2021)In studies of electron and proton radiotherapy, ultrahigh dose rates of FLASH radiotherapy appear to produce fewer toxicities than standard dose rates while maintaining local tumor control. FLASHproton radiotherapy (F-PRT) ... -
Frequency dependent non-thermal effects of oscillating electric fields in the microwave region on the properties of a solvated lysozyme system: A molecular dynamics study
(2017)The use of microwaves in every day's applications raises issues regarding the non thermal biological effects of microwaves. In this work we employ molecular dynamics simulations to advance further the dielectric studies ... -
High resolution computed tomography findings on the lung of early breast-cancer patients treated by postoperative breast irradiation with a hypofractionated radiotherapy schedule
(2005)BACKGROUND: Hypofractionated breast radiotherapy (RT), although convenient for patients and health care systems, could have a negative impact on normal tissues such as lung. AIM: To evaluate radiation-induced lung toxicity ... -
Irradiation induced inversions suppress recombination between the M locus and morphological markers in Aedes aegypti
(2020)Background: Aedes aegypti is the primary vector of arthropod-borne viruses and one of the most widespread and invasive mosquito species. Due to the lack of efficient specific drugs or vaccination strategies, vector population ... -
Is locally advanced head-neck cancer one more candidate for accelerated hypofractionation?
(2021)Background/Aim: Hypofractionated accelerated radiotherapy (HypoAR) is widely applied for the treatment of early laryngeal cancer. Its role in locally advanced head-neck cancer (LA-HNC) is unexplored. Patients and Methods: ... -
Lapatinib with whole brain radiotherapy in patients with brain metastases from breast and non-small cell lung cancer: a phase II study of the Hellenic Cooperative Oncology Group (HeCOG)
(2017)Small molecules, mainly tyrosine kinase inhibitors, are currently used in various malignancies. Lapatinib, a dual inhibitor of EGFR/HER2 tyrosine kinases, has demonstrated effectiveness in brain metastases from HER2-overexpressing ... -
Molecular determinants of radiosensitivity in normal and tumor tissue: A bioinformatic approach
(2017)Although radiation therapy is a treatment of choice for cancer, a high percentage of patients develop adverse effects in normal tissue following radiotherapy, mainly, due to genetic factors. Notably, although it is established ... -
Oligometastasis and local ablation in the era of systemic targeted and immunotherapy
(2020)Background: During these last years, new agents have dramatically improved the survival of the metastatic patients. Oligometastases represent a continuous field of interest in which the integration of metastases-directed ... -
Prognostic significance and therapeutic implications of Caveolin-1 in gastrointestinal tract malignancies
(2022)Caveolin-1 (CAV1) is expressed in several solid tumors both in cancerous cells as well as in tumor stroma and is reported to be related to cancer progression, metastasis, therapy resistance and clinical outcomes. Many ... -
Unraveling the mechanisms of extreme radioresistance in prokaryotes: Lessons from nature
(2016)The last 50 years, a variety of archaea and bacteria able to withstand extremely high doses of ionizing radiation, have been discovered. Several lines of evidence suggest a variety of mechanisms explaining the extreme ... -
Use of ultrasounds in the food industry–Methods and effects on quality, safety, and organoleptic characteristics of foods: A review
(2017)The use of ultrasounds has recently gained significant interest in the food industry mainly due to the new trends of consumers toward functional foods. Offering several advantages, this form of energy can be applied for ... -
UVB-mediated down-regulation of proteasome in cultured human primary pterygium fibroblasts
(2018)Background: Pterygium is a condition characterized by epithelial overgrowth of the cornea, inflammatory cell infiltration and an abnormal extracellular matrix accumulation. Chronic UV exposure is considered as a pathogenic ... -
Vaginal dilator use to promote sexual wellbeing after radiotherapy in gynecological cancer survivors
(2022)AbstractThis study investigated the efficacy of a vaginal dilator (VD) for the treatment of radiation-induced vaginal stenosis (VS) and the effect of a VD on sexual quality of life.Fifty three patients with endometrial or ...
