When the body detects something that can cause disease, like a virus or bacteria or a cancer cell, the immune system sends out specific cells to try to destroy the invader. Antibodies connect to harmful molecules. The antibodies act as flags for other immune system cells to attack the harmful molecule. Monoclonal antibodies are made in a lab and are engineered to attach to very specific targets...

Solar ultraviolet-B (UVB) radiation is deleterious to plant-dwelling mites. Neoseiulus californicus (McGregor) is a predominant predator of agriculturally important pest species of spider mite. However, phytoseiid mites are more vulnerable to UVB radiation than spider mites. Thus, the UVB radiation may influence decision making in foraging phytoseiid mites whether disperse or not. We tested the...

background: recently, there have been many studies on the harmful effects of radiation and the regulations on radiation safety have been toughened both at the in nation and abroad. this study aims to identify the perceptions and actions taken as to radiation safety, and the degree of knowledge related to radiation held by the radiologists working in large hospitals. materials and methods: the r...

PURPOSE We assessed and evaluated attitudes and knowledge regarding ionizing radiation of urology surgery room staff. MATERIALS AND METHODS A questionnaire was sent by e-mail to urology surgery room personnel in Turkey, between June and August 2013. The questionnaire included demographic questions and questions regarding radiation exposure and protection. RESULTS In total, 127 questionnaire...

The long established notion that UV irradiation is always harmful to patients with systemic lupus erythematosus has been challenged by some recent reports of benefit using a form of phototherapy with UV-A1. In the review we discuss the different types of UV radiation, the links between certain forms of such radiation and clinical manifestations and consider the mechanisms involved.

Habitat use by animals often reflects the balance between conflicting demands such as foraging and avoiding predation. Environmental stressors such as temperature can also affect habitat use in many organisms, particularly in ectothermic animals. For example, warm, shallow thermal regimes in ponds can optimize growth and developmental rate of amphibian larvae but may also expose larvae to poten...

Radiation is the transmission of energy through space and matter. There are several forms of radiation, including ionizing and nonionizing. X-rays are the ionizing radiation used extensively in medical and dental practice. Even though they provide useful information and aid in diagnosis, they also have the potential to cause harmful effects. In dentistry, it is mainly used for diagnostic purpos...
