IN comparative studies of the mutagenic action of ionizing and ultraviolet radiation on conidia of the fungus Glomerella (5) it was evident that the shape of the mutation curve was different for the two types of radiation. The dose-mutation curve for the surviving spores was essentially linear for the ionizing radiations, but with the ultraviolet radiation the mutation curve rose with increasin...

The objective of the current study was to investigate the protective effects of hesperidin against oxidative stress, altered cytokines levels and histological changes in rats induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Rats were divided randomly into four equal groups (Control, TCDD, hesperidin and TCDD+hesperidin). TCDD and hesperidin were given by gavage, dissolved in corn oil at d...

Radiation-induced damage is a complex network of interlinked signaling pathways, which may result in apoptosis, cell cycle arrest, DNA repair, and cancer. The development of thyroid cancer in response to radiation, from nuclear catastrophes to chemotherapy, has long been an object of study. A basic overview of the ionizing and non-ionizing radiation effects of the sensitivity of the thyroid gla...

BACKGROUND We have previously shown that a combination of glucosyl hesperidin (G-hesperidin) plus caffeine reduces accumulation of body fat, whereas G-hesperidin or caffeine alone shows little effect on high-fat diet-induced obesity in mice. The aim of this study is to evaluate the anti-obesity effect of G-hesperidin plus caffeine on body fat and serum TG in healthy subjects with moderately hig...

CONTEXT Citrus fruits contain unique flavanones. One of the most abundant of the flavanones, hesperidin, has been shown to prevent bone loss in ovariectomized rats. OBJECTIVE The objective of the study was to measure the effect of hesperidin with or without calcium supplementation on bone calcium retention in postmenopausal women. DESIGN The study was a double-blind, placebo-controlled, ran...

Radiation is the emission or transmission of energy as waves particles through space a material medium which able to penetrate various materials and often categorized either ionizing non-ionizing depending on radiated particles. processing can be defined exposure with high radiation change their physical, chemical, biological characteristics, increase usefulness, safety purpose, reduce harmful ...

Astrophysical ionizing radiation events have been recognized as a potential threat to life on Earth, primarily through depletion of stratospheric ozone and subsequent increase in surface-level solar ultraviolet radiation. Simulations of the atmospheric effects of a variety of events (such as supernovae, gamma-ray bursts, and solar proton events) have been previously published, along with estima...

New technologies are evolving day to day life to facilitate human being. Mobile communication is currently the fastest growing communication system in the telecommunication industry. Due to the increased number of users using the mobile phone, the concern is now focused towards electromagnetic radiations emitted by the mobile phones itself. Electromagnetic radiation can be classified into ioniz...

introduction : the fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. to disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofrequ...

background : effects of electromagnetic fields on healing have been investigated for centuries. substantial data indicates that exposure to electromagnetic field can lead to enhanced healing in both soft and hard tissues. helmholtz coil is a device that generates pulsed electromagnetic fields. objective : in this study, a pair of helmholtz coils for enhancing the healing process in periodontiti...
