Background and purpose : Instalation of protective barrier against diagnostic x-ray is generally done based on the recommendations of NCRP49. There are analytic methods for designing protective barriers howerer, they lack sufficient efficiency and considering the NCRP49 reports, designing mechanical protective barrier in order to protect the initial x-ray radiation and absorption of the ray q...

Reflecting on the 40th anniversary of the Oncology Nursing Society led me to recall my own 30-plus years in nursing and how, as a new graduate nurse, almost all oncology care was delivered in the inpatient setting. In my first few years of practice, I mixed my patients' chemotherapy in a medicine room without a ventilated hood and administered those medications without personal protective equip...

OBJECTIVE The proper use of safety measures by welders is an important way of preventing and/or reducing a variety of health hazards that they are exposed to during welding. There is a lack of knowledge about hazards and personal protective equipments (PPEs) and the use of PPE among the welders in Nepal is limited. We designed a study to assess welders' awareness of hazards and PPE, and the use...

The treatment of cancer with chemotherapeutic agents and radiation has two major problems: time-dependent development of tumor resistance to therapy (chemoresistance and radioresistance) and nonspecific toxicity toward normal cells. Many plant-derived polyphenols have been studied intently for their potential chemopreventive properties and are pharmacologically safe. These compounds include gen...

A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, ch...

We analyzed occupational exposure to potentially infectious body fluids among health care workers (HCWs). Nurses were the most common exposed category of HCWs. In 73.6% cases needle sticks had been the reason of exposure. Recapping a needle was the cause of exposure in 6.9% accidents. Among 189 registered HCWs, 66 (34.9%) performed invasive procedures without any personal protective equipment. ...

Introduction: Despite the extensive use of ionizing radiation in diagnosis and therapeutic procedures, development of radio-protector agents is important in modulating normal tissue damages. Hesperidin(HES) is a Flavanone glycoside, belonging to the Flavonoid family in human diet abundantly and noted for its many beneficial effects. The aim of present study was investigated to ...
