Effective protection from the harmful effects of UV radiation may be achieved by using sunscreens containing organic or inorganic UV filters. The number of currently available UV filters is limited and some of the allowed molecules possess limitations such as systemic absorption, endocrine disruption properties, contact and photocontact allergy ind...

Two nonrelated Goeldi's monkeys (Callimico goeldii) from the same enclosure developed multifocal alopecia with hyperkeratotic to ulcerative skin lesions on the lower abdomen and inner thighs. Necropsy samples of the first animal showed hyperplastic dermatitis together with in situ carcinoma and intralesional Demodex organisms. The second monkey dev...

BackgroundSpathiphyllum is one of the best plants for indoor gardening as it is a rhizome and undemanding of light care. It is a member of lily family (Araceae). The plant itself should live for 10 years or more if not maltreated. Spthiphyllum cannifolium plants are used in clean air study for their ability to remove formaldehyde, benezyne, and CO2...

To report a case of amelanotic ciliochoroidal melanoma in a patient with oculocutaneous albinism. A 76-year-old Caucasian male with a past medical history of oculocutaneous albinism and recurrent urothelial carcinoma was found to have a mass in the left eye, suspicious for ciliochoroidal melanoma. On examination, visual acuity was 20/400 in both ey...

Evidence suggests that beta human papillomaviruses (HPVs), together with ultraviolet radiation, contribute to the development of cutaneous squamous cell carcinoma. Beta HPVs appear to be not the main drivers of carcinogenesis but rather facilitators of the accumulation of ultraviolet-induced DNA mutations. Beta HPVs are promoters of skin carcinogen...

Climate changes and anthropogenic factors are the main factors contributing to the destruction of natural ecosystems. The aim of this study was to investigate the extent to which wild plants adapt to UV, gamma background, and gross beta activity, as well as the possible damage that can be recorded in plants growing at different altitudes in Rila Mo...
A vegetable tannin, a flavonoid-type natural polyphenolic compound, was used to promote the stabilization of polyurethane foams against UV radiation. Several polyurethane foams were synthesized by using an isocyanate, and a mixture of ethoxylated cocoalkyl amine and vegetable tannin. The content of vegetable tannin was varied from 0 to 40 wt %. The...

AbstractPhotoelectric characteristics of the focal plane arrays working in the visual-blind UV spectral range are studied. The dependences of the signal-to-noise ratio (SNR) on the integration time and the bias voltage on photodiodes and I–V characteristics of the photodiodes are measured. It is shown that ROIC noise dominates over the noise of pho...

AbstractUV radiation is calculated for Russian regions where anomalies of the total ozone content were observed in the first quarter of 2016. Winter ozone depletion in northern regions of Siberia, even to the levels of the so-called ozone hole, is not critical. However, much weaker ozone reduction in the early spring can lead to dangerous levels of...
