Ionizing radiation (IR) is used to treat more than half of human cancer patients. The therapeutic effect of IR is due to its ability to induce apoptosis. Success of radiation therapy relies not only on apoptosis induction but also on whether surviving cancer cells proliferate and regenerate a tumor. Drosophila melanogaster is a premier genetic model and, relevant to radiation biology of cancer, Drosophila larvae display an amazing capacity to regenerate. IR doses that kill more than half of the cells in larval tissues still allow complete regeneration to produce an adult fly of normal size and pattern. It is by understanding not only the initial effects of IR such as DNA damage and cell death but also longer-term regenerative responses that we may manipulate and improve radiation therapy of cancer. In this regard, Drosophila offers an unparalleled model to study both types of responses ...

As part of a tumour growth inhibition study, SK-N-SH xenografts were generated in BALB/c nu/nu mice. Mice (n = 8) were placed in a printed MR- and CT-compatible plastic cradle, imaged using a 4.7-T MRI scanner and then transferred to a small animal radiation research platform (SARRP) irradiator with on-board CBCT. MRI/CBCT co-registration was performed to enable RT planning using the soft-tissue contrast afforded by MRI prior to delivery of RT (5 Gy). Tumour response was assessed by serial MRI and calliper measurements.. ...

You all know the situation when you have so much to do that you seem to spend the whole day at work - you are sitting at your lab bench by a little lamp with pipette in hand or in the dimly lit room behind your computer, trying to make some sense of the data. And suddenly you get your blood results back: your levels of Vitamin D are critical! At the moment, it also might be because of the winter time and not because of the long hours in a dark laboratory (which, unfortunately, might be my case...). It is cloudy all the time, the sun rises late (you are already at work) and sets early (you are still at work) so you have basically no chance to produce any of the precious Vitamin D even though evolution equipped you perfectly (probably did not account for scientists...). Moreover, it seems that even your T-lymphocytes are becoming somehow lazy without the sun[1]! Even though it seems grim, dont worry, there is no need to panic. We all can get better during the 63rd annual Radiation Research ...

Images acquired by X-rays provide doctors with anatomical information and assist in diagnoses or progression of health problems. In a similar manner, this imaging technique is used for clinical and preclinical research. When used by doctors or in clinical research the amount of X-ray (ionising radiation) dose a person receives is regulated. This is not true in preclinical research where overexposure to ionising radiation occurs since X-ray doses are unknown, unregulated and there are no guidelines. Overexposure potentially causes unnecessary suffering to animals and may impact research results, especially in longitudinal studies.. The goal of this project is to set X-ray (CT) dose guidelines in order to minimise or eliminate any animal suffering and reduce the number of animals used by refining CT imaging experimental methods. It has been known for years that ionising radiation causes cell/DNA damage. For instance, ionising radiation is used as a cancer treatment to kill cells. Worldwide Cancer ...
CLINICAL RADIOBIOLOGY. Exchanges with the local Teachings Hospitals and pursuing Radiobiology matters that is of direct clinical relevance is an ongoing project. As a result 4 research papers on the clinical outcome of particle therapy protocols have been published during recent years. This includes a retrospective study evaluating the control rates of skull base meningiomas for patients treated using stereotactic proton therapy. By analysing different dose / fractionating schedules a tissue specific repair constant could be estimated from the clinical data that proves to be most useful to calculate the physical radiation dose needed for a given treatment protocol (Int. J Rad. Oncol. Biol. Phys. 2001). Also, it could be demonstrated that the hypofractionated proton treatments given at iThemba is iso-effectiveness to both conventional fractionated protocols and radiosurgery treatments given at other facilities.. ...

If a woman aged 35 years received a 0.01 Gy average breast dose from a mammographic examination, her lifetime risk of spontaneous breast cancer of about 7.58% might be expected to increase to 7.61%. If on the other hand, one million women received the same dose, 234-425 excess breast cancers are estimated to develop during the lifetimes of these women as a result of this radiation exposure. Age at irradiation has been found to be a major parameter of risk in epidemiological surveys. Women irradiated between ages 10 and 19 years of age were more susceptible than other ages. Data from the tuberculosis-fluoroscopy series suggest fractionating a large dose over many years does not mitigate the cancer risk. Latency is apparently unrelated to dose. The minimal latent period in the two largest series of irradiated breast cancer cases was found to be about 5 years in women irradiated at age 30 year or over, with perhaps another 5 years required before the excess risk became substantial. In younger ...
In view of their properties, laser-driven ion beams have the potential to be employed in innovative applications in the scientific, technological and medical areas. Among these, a particularly high-profile application is particle therapy for cancer treatment, which however requires significant improvements from current performances of laser-driven accelerators. The focus of current research in this field is on developing suitable strategies enabling laser-accelerated ions to match these requirements, while exploiting some of the unique features of a laser-driven process. LIBRA is a UK-wide consortium, aiming to address these issues, and develop laser-driven ion sources suitable for applicative purposes, with a particular focus on biomedical applications. We will report on the activities of the consortium aimed to optimizing the properties of the beams, by developing and employing advanced targetry and by exploring novel acceleration regimes enabling production of beams with reduced energy ...

The health effects of living/working near power transmission lines. A British study conducted by Dennis Henshaw and colleagues at the University of Bristol, published in the International Journal of Radiation Biology on February 14, 1996, found that power lines attract particles from radon gas, a known carcinogen. They have found evidence that the harmful concentrations of radon products may be present around overhead power lines. The electromagnetic fields associated with the lines can therefore concentrate a cocktail of potential carcinogens.. On November 28, 1999, The Sunday Times reported on a new study by Professor Henshaw to be published in the International Journal of Radiation Biology. The study confirms that people living near them are exposed to radiation levels dozens of times greater than the legal limit.. The research firmly links the power lines with childhood leukaemia and other forms of cancer. …In some areas children living near power lines could receive doses of 95 ...

Nuclear Regulatory Commission and Corporate Options for DU Disposal Risk Long-Term Violation of Health and Environmental Standards, New Analysis Indicates. TAKOMA PARK, MD, FEB. 23, 2005 - A new report about a uranium enrichment plant proposed to be built in New Mexico concludes that it would cost between $3 billion and $4 billion to properly manage and dispose of the depleted uranium (DU) waste that the plant would generate. Such high costs could not be recovered from the customers for enrichment services.. The report also discusses recent research on the health effects of DU, much of it performed at the Armed Forces Radiobiology Research Institute in Bethesda, Maryland after the 1991 Gulf War, that has implications far wider than the New Mexico plant. The research indicates that depleted uranium may be mutagenic, tumorigenic, teratogenic, cytotoxic, and neurotoxic, including in a manner analogous to exposure to lead. [1] It may also cross the placenta and harm the embryo/fetus. There is also ...

Radiation Oncology is a Clinical discipline and the most important activity within the Department is patient service, as more than 50% of cancers are curable. Where it is not possible to cure, the aim is to improve patient well-being. Palliative treatment is important in order to relieve symptoms such as pain and bleeding and may enable patients to return to useful functioning within their families and work place.. Approximately 3000 new patients are seen per annum and many patients return for follow up visits for long periods of time.. The planning and administration of Radiation Therapy is technically exacting and must be done with care and skill, as large doses of irradiation are delivered to the patient. Close collaboration with Medical Physics, Radiobiology, Planning and Treatment Radiation Therapists and Oncology Nursing staff is essential.. Within the Radiation Oncology Division, all new patients are assessed in multi-disciplinary clinics. The most appropriate treatment is recommended by ...

Yoshida, T., Tanabe, T., Okabe, Y., Sawasaki, T. and Chen, A. Decomposition of Carbon Dioxide by Metals during Gamma Irradiation. Radiat. Res. 164, 332-335 (2005).. We have proposed a technique to enhance the decomposition of carbon dioxide by γ irradiation. This is possible by putting metal components into CO2 gas to promote the conversion of γ rays to lower-energy electrons through Compton, photoelectron and cascading electron knock-on events in metals. Numerical simulations using the EGS code indicated that the number of lower-energy electrons ejected from metals into CO2 gas increases with increasing Z number and/or density of the metals; this was supported by the experimental results, i.e., the CO2-containing metals with a higher Z number exhibited a greater efficiency for production of CO. In addition, production of CO could be enhanced by carefully controlling the volume and surface area of metal components as well as the proximity to adjacent metal components. These experimental ...
X-Irradiation delays division of heat-synchronized Tetrahymena pyriformis (a ciliate protozoon) if exposure occurs prior to a critical time after the end of the synchronizing treatment (EST). Exposure after this critical time does not significantly delay the first synchronized division but does delay the second. The time of the transition from a state where the cells are delayed to one where they are not is somewhat dose dependent: within limits, the larger the exposure, the later is the transition time. The division delay response is always correlated with a resorption of the oral primordium of the presumptive posterior daughter cell. The amount of time for resorption varies with the time after EST at which the cells are irradiated and is dose dependent. The data are consistent with the hypothesis that irradiation produces damage during all parts of the synchronized cell cycle, but that, depending on the dose and the time of irradiation after EST, the damage may or may not trigger a response ...
Radioprotection, theoretical calculation of doses - radioactive fallout - biological effects of ionising radiation or radiobiology - experimental studies (dosimetry, reactor physics, radiochemistry), radiobiological risk management
I am a Marie Sklodowska Curie Fellow in the QUASAR group of the University of Liverpool, headed by Professor Carsten Welsch, and I am based at the Cockcroft Institute, UK. I am also part of the Optimising Medical Accelerator (OMA) training network, and my project is looking at both beam diagnostics and radiobiology.. In one of my studies, we are trying to figure out why proton therapy - a new form of cancer treatment - is more effective than conventional radiotherapy at the biological level: why it does more cluster damage to DNA, why this makes it harder to repair, or if it creates more strand breaks… basically pairing up the physics with the biology.. Although significant progress has been made in the use of particle beams for cancer treatment, there are still a lot of unanswered questions in proton therapy.. Its very difficult to pinpoint exactly why proton therapy is effective overall, because there are so many different factors. One thing that is agreed is that proton therapy can do more ...
R.E. Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology, NAS of Ukraine, Kyiv, Ukraine. [email protected] Introduction: It is known that the tumor growth is accompanied by changes of redox carriers in the mitochondrial electron transport chain. These changes may result in decrease of energy metabolism. The functional state of the mitochondrial electron transport chain also defines the intensity of production and accumulation of the oxygen and nitrogen reactive species (ROS and NOS), which affect different biological processes and can promote cell damage. It has already been observed that non-cytotoxic doses of oxyresveratrol (OXY) showed significant antineoplastic and anti-metastatic effects and prolonged the life of animals with tumors. Aim: To analyze the influence of OXY on the mitochondrial iron-sulfur centers and nitrosyl-hem complexes of tumor cells during Lewis lung carcinoma growth. Materials and Methods: EPR method was used to analyze the OXY influence on the ...
In 1939 Howard married Patrick William Rolleston and took up a Finney-Howell Research Fellowship at McGill. She was demonstrator in Genetics at McGill into 1940 and in the course of this work she discovered a new murine mutation.[4] In 1940, her first son, Francis, was born, followed by a second son, Patrick, in 1942. After World War II, she moved with her husband and children to England. However, her husband died in 1947 and her colleague Jack Boag would later note that she had to find work which would allow her freedom to bring up her two young sons.[4] At the same time, Louis Harold Gray was looking for a cytologist to work in his radiobiology team at the UK Medical Research Councils Radiotherapeutic Research Unit at Hammersmith Hospital. By fortunate chance he was introduced to Dr. Howard and flexible working arrangements were readily agreed.[4] On a preliminary visit to the Radiotherapeutic Research Unit, she met physicist Stephen Pelc who had developed a variant autoradiograph ...

VCU Massey Cancer Center has opened a Phase I clinical trial testing an innovative radiation therapy for patients with early stage prostate cancer that has the potential to drastically reduce treatment time. In comparison to the standard schedule of eight weeks of daily external beam radiation therapy, the new technique requires just four treatments, administered twice in the first week and twice in the fourth week.. Many patients travel a significant distance to undergo radiation therapy at Massey, says the creator of the innovative dosing schedule and lead investigator on the clinical trial Mitchell Anscher, M.D., Florence and Hyman Meyers Chair of Radiation Oncology and co-leader of the Radiation Biology and Oncology program at VCU Massey Cancer Center. If successful, not only does this shortened dosing schedule mean less time out of work and less time in the clinic for patients, but we also estimate that it will cost at least $7,000 less than the standard eight-week treatment ...
University of Iowa News. June 1, 2006. UI Cancer Researchers Receive Grant To Study Cell Cycle Checkpoints University of Iowa Roy J. and Lucille A. Carver College of Medicine researchers in the UI Holden Comprehensive Cancer Center have been awarded a five-year, $1.5 million grant from the National Cancer Institute to investigate a new hypothesis about how the mammalian cell cycle is regulated.. The cell cycle is the normal, orderly growth and division of cells. This process, also known as proliferation, is usually tightly controlled, but in cancers the process goes awry and malignant cells proliferate in an uncontrolled manner. Understanding the genetic and biochemical mechanisms that govern the cell cycle could lead to new and better cancer therapies that kill cancer cells but are not toxic to normal cells. The research team, led by Prabhat Goswami, Ph.D., UI assistant professor of radiation oncology in the Free Radical and Radiation Biology Graduate Program, will test the idea that reactive ...

Prediction of radiobiological response is a major challenge in radiotherapy. Of several radiobiological models, the linear-quadratic (LQ) model has been best validated by experimental and clinical data. Clinically, the LQ model is mainly used to estimate equivalent radiotherapy schedules (e.g. calculate the equivalent dose in 2 Gy fractions, EQD2), but increasingly also to predict tumour control probability (TCP) and normal tissue complication probability (NTCP) using logistic models. The selection of accurate LQ parameters α, β and α/β is pivotal for a reliable estimate of radiation response. The aim of this review is to provide an overview of published values for the LQ parameters of human tumours as a guideline for radiation oncologists and radiation researchers to select appropriate radiobiological parameter values for LQ modelling in clinical radiotherapy. We performed a systematic literature search and found sixty-four clinical studies reporting α, β and α/β for tumours. Tumour site,

Sato, Tatsuhiko. Hoshasen Seibutsu Kenkyu, 48(2), p.137 - 146, 2013/06. Radiation doses are inhomogeneously distributed through microscopic sites such as DNA and cell nuclei. Although this inhomogeneity has been regarded as an important factor to determine the relative biological effectiveness (RBE) over 50 years, it had not been frequently used in the quantitative analyses of radiation research because of the difficulty of evaluating the probability density function of dose in microscopic sites. We therefore developed a computational method for calculating the probability density functions in any radiation field and target size by means of combining a multi-scale particle transport simulation code with several mathematical models. Utilizing this method, we established a model for estimating cell-survival fractions in any radiation field. This model employs the probability density functions of domain and cell-nucleus doses as the indexes for characterizing the radiation fields.. ...

The concept of identity is used both (i) to distinguish a system as a particular material entity that is conserved as such in a given environment (token-identity: i.e., identity as permanence or endurance over time), and (ii) to relate a system with other members of a set (type-identity: i.e., identity as an equivalence relationship). Biological systems are characterized, in a minimal and universal sense, by a highly complex and dynamic, far-from-equilibrium organization of very diverse molecular components and transformation processes (i.e., genetically instructed cellular metabolisms) that maintain themselves in constant interaction with their corresponding environments, including other systems of similar nature. More precisely, all living entities depend on a deeply convoluted organization of molecules and processes (a naturalized von Neumann constructor architecture) that subsumes, in the form of current individuals (autonomous cells), a history of ecological and evolutionary interactions (across

Hofer, M., Pospisil, M., Dugek, L., Hoferova, Z. and Weiterova, L. A Single Dose of an Inhibitor of Cyclooxygenase 2, Meloxicam, Administered Shortly after Irradiation Increases Survival of Lethally Irradiated Mice. Radiat. Res. 176, 269-272 (2011). This study extends earlier findings of the authors demonstrating that meloxicam, a selective inhibitor of cyclooxygenase 2, supports hematopoietic recovery in sublethally irradiated mice and is radioprotective when given before irradiation. We report here that when meloxicam was administered in a single dose 1 h after a lethal 9-Gy whole-body dose, an increased 30-day survival was achieved. Additional studies showed that administration of meloxicam 24 h after lethal irradiation is ineffective and its repeated administration deleterious. Possible mechanisms of the therapeutic effects of meloxicam administered early after irradiation are discussed. (C) 2011 by Radiation Research Society. ...

According to the concept of the TESLA Accelerator Installation, the channel for production of radioisotopes has to routinely produce Tl-201, In-111, Ga-67, I-123 and F-18, and a number of other radionuclides for experimental purposes. The production of I-123 and F-18 will be performed in dedicated, commercial target stations, while a versatile solid target irradiation system is designed for the routine and experimental production of all other radioisotopes. The solid target station is designed to accept targets for both the 7degrees and 90degrees irradiation geometry. The targets used for the routine production will be prepared by electroplating on a silver substrate. They can be irradiated with a 1.5 kW beam using the 7degrees geometry. The cooling of these targets is enhanced by fins on the back of the silver substrate designed so that the highest temperature on the surface of the target does not exceed 110degreesC. The irradiation procedures will conform to the GMP requirements for ...the ...
