the harmful effects of the long-term ocular exposure to cumulative levels of infrared radiation (ir) in glassblowing and foundries have been recognized since the late 19th century. these effects include cataracts, keratitis, and chronic dry eye problems. therefore, infrared radiation measurements are critical and need to be assessed regularly in the industries and workplaces where there are hig...

high intensity optical radiation can cause damage to the eye and intense radiation in the range of 770-1400 nm can cause thermal retinal damage. in the workplaces where there are high temperature sources, the workers in front of these hot  sources without bright light maybe exposed to the  intense ir radiation, thus regular measurement of these radiations seems crucial. measurement of ir radiat...

Signaling through the insulin-like growth factor-I receptor (IGF-IR) is implicated in cellular proliferation, apoptosis, carcinogenesis, metastasis, and resistance to cytotoxic cancer therapies. Targeted disruption of IGF-IR signaling combined with cytotoxic therapy may therefore yield improved anticancer efficacy over conventional treatments alone. In this study, a fully human anti-IGF-IR mono...

micrornas (mirnas) represent a class of small non-coding rna molecules that regulate gene expression at the post-transcriptional level. they play a crucial role in diverse cellular pathways. ionizing radiation (ir) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. recently it has been discovered that mi...

2. Ionizing radiation Individual types of IR possess different biological effectiveness. In order to it unit of equivalent dose was defined – 1 Sievert (Sv). Equivalent dose represents absorbed dose multiplied with factor connected with biological effectiveness of IR. More precisely, this factor expresses how many times is precise IR effective than photons of X or gamma radiation (röentgen radi...

For more than a century, solar radiation has been known to contribute significantly to the extrinsic aging of skin. Until recently, this was almost exclusively attributed to the photodamage caused by ultraviolet (UV) light. However, a growing body of evidence now indicates that both infrared (IR) and visible light may also contribute to extrinsic skin aging. Infrared radiation, comprised of IR-...

Interventional procedures are used by a significant number of medical specialities. Radiation protection (RP) for patients and staff is one of the main issues in Interventional Radiology (IR). UNSCEAR, ICRP and IAEA have devoted significant time over the last years to improve radiation safety in IR. Several combined factors: prolonged localized fluoroscopy, multiple radiographic exposures, and ...

Targeted disruption of IGF-IR signaling combined with cytotoxic therapy may therefore yield improved anticancer efficacy over conventional treatments alone.

World conditions place large populations at risk from ionizing radiation (IR) from detonation of dirty bombs or nuclear devices. In a subgroup of patients, ionizing radiation exposure would be followed by a secondary infection. The effects of radiation combined injury are potentially more lethal than either insult in isolation. The purpose of this study was to determine mechanisms of mortality ...

In a synchrotron radiation source coherent infrared (IR) radiation is emitted when the bunch length is comparable to the wavelength of the emitted radiation. To generate coherent THz (far IR) radiation, the ANKA storage ring is operated regularly in a dedicated low-alpha optics. Different bunch lengths, corresponding to different spectral ranges of the THz spectrum and various electron beam ene...
