Ultraviolet Rays
That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
Ultraviolet Therapy
The use of ultraviolet electromagnetic radiation in the treatment of disease, usually of the skin. This is the part of the sun's spectrum that causes sunburn and tanning. Ultraviolet A, used in PUVA, is closer to visible light and less damaging than Ultraviolet B, which is ionizing.
Spectrophotometry, Ultraviolet
Determination of the spectra of ultraviolet absorption by specific molecules in gases or liquids, for example Cl2, SO2, NO2, CS2, ozone, mercury vapor, and various unsaturated compounds. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Gamma Rays
Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.
Radiation Effects
The effects of ionizing and nonionizing radiation upon living organisms, organs and tissues, and their constituents, and upon physiologic processes. It includes the effect of irradiation on food, drugs, and chemicals.
PUVA Therapy
Photochemotherapy using PSORALENS as the photosensitizing agent and ultraviolet light type A (UVA).

JNK2 is required for efficient T-cell activation and apoptosis but not for normal lymphocyte development. (1/12422)

BACKGROUND: The Jun N-terminal kinase (JNK) signaling pathway has been implicated in cell proliferation and apoptosis, but its function seems to depend on the cell type and inducing signal. In T cells, JNK has been implicated in both antigen-induced activation and apoptosis. RESULTS: We generated mice lacking the JNK2 isozymes. The mutant mice were healthy and fertile but defective in peripheral T-cell activation induced by antibody to the CD3 component of the T-cell receptor (TCR) complex - proliferation and production of interleukin-2 (IL-2), IL-4 and interferon-gamma (IFN-gamma) were reduced. The proliferation defect was restored by exogenous IL-2. B-cell activation was normal in the absence of JNK2. Activation-induced peripheral T-cell apoptosis was comparable between mutant and wild-type mice, but immature (CD4(+) CD8(+)) thymocytes lacking JNK2 were resistant to apoptosis induced by administration of anti-CD3 antibody in vivo. The lack of JNK2 also resulted in partial resistance of thymocytes to anti-CD3 antibody in vitro, but had little or no effect on apoptosis induced by anti-Fas antibody, dexamethasone or ultraviolet-C (UVC) radiation. CONCLUSIONS: JNK2 is essential for efficient activation of peripheral T cells but not B cells. Peripheral T-cell activation is probably required indirectly for induction of thymocyte apoptosis resulting from administration of anti-CD3 antibody in vivo. JNK2 functions in a cell-type-specific and stimulus-dependent manner, being required for apoptosis of immature thymocytes induced by anti-CD3 antibody but not for apoptosis induced by anti-Fas antibody, UVC or dexamethasone. JNK2 is not required for activation-induced cell death of mature T cells.  (+info)

Activation of telomerase and its association with G1-phase of the cell cycle during UVB-induced skin tumorigenesis in SKH-1 hairless mouse. (2/12422)

Telomerase is a ribonucleoprotein enzyme that adds hexanucleotide repeats TTAGGG to the ends of chromosomes. Telomerase activation is known to play a crucial role in cell-immortalization and carcinogenesis. Telomerase is shown to have a correlation with cell cycle progression, which is controlled by the regulation of cyclins, cyclin dependent kinases (cdks) and cyclin dependent kinase inhibitors (cdkis). Abnormal expression of these regulatory molecules may cause alterations in cell cycle with uncontrolled cell growth, a universal feature of neoplasia. Skin cancer is the most prevalent form of cancer in humans and the solar UV radiation is its major cause. Here, we investigated modulation in telomerase activity and protein expression of cell cycle regulatory molecules during the development of UVB-induced tumors in SKH-1 hairless mice. The mice were exposed to 180 mjoules/cm2 UVB radiation, thrice weekly for 24 weeks. The animals were sacrificed at 4 week intervals and the studies were performed in epidermis. Telomerase activity was barely detectable in the epidermis of non-irradiated mouse. UVB exposure resulted in a progressive increase in telomerase activity starting from the 4th week of exposure. The increased telomerase activity either persisted or further increased with the increased exposure. In papillomas and carcinomas the enzyme activity was comparable and was 45-fold higher than in the epidermis of control mice. Western blot analysis showed an upregulation in the protein expression of cyclin D1 and cyclin E and their regulatory subunits cdk4 and cdk2 during the course of UVB exposure and in papillomas and carcinomas. The protein expression of cdk6 and ckis viz. p16/Ink4A, p21/Waf1 and p27/Kip1 did not show any significant change in UVB exposed skin, but significant upregulation was observed both in papillomas and carcinomas. The results suggest that telomerase activation may be involved in UVB-induced tumorigenesis in mouse skin and that increased telomerase activity may be associated with G1 phase of the cell cycle.  (+info)

Activation of c-Jun N-terminal kinase 1 by UV irradiation is inhibited by wortmannin without affecting c-iun expression. (3/12422)

Activation of c-Jun N-terminal kinases (JNKs)/stress-activated protein kinases is an early response of cells upon exposure to DNA-damaging agents. JNK-mediated phosphorylation of c-Jun is currently understood to stimulate the transactivating potency of AP-1 (e.g., c-Jun/c-Fos; c-Jun/ATF-2), thereby increasing the expression of AP-1 target genes. Here we show that stimulation of JNK1 activity is not a general early response of cells exposed to genotoxic agents. Treatment of NIH 3T3 cells with UV light (UV-C) as well as with methyl methanesulfonate (MMS) caused activation of JNK1 and an increase in c-Jun protein and AP-1 binding activity, whereas antineoplastic drugs such as mafosfamide, mitomycin C, N-hydroxyethyl-N-chloroethylnitrosourea, and treosulfan did not elicit this response. The phosphatidylinositol 3-kinase inhibitor wortmannin specifically blocked the UV-stimulated activation of JNK1 but did not affect UV-driven activation of extracellular regulated kinase 2 (ERK2). To investigate the significance of JNK1 for transactivation of c-jun, we analyzed the effect of UV irradiation on c-jun expression under conditions of wortmannin-mediated inhibition of UV-induced stimulation of JNK1. Neither the UV-induced increase in c-jun mRNA, c-Jun protein, and AP-1 binding nor the activation of the collagenase and c-jun promoters was affected by wortmannin. In contrast, the mitogen-activated protein kinase/ERK kinase inhibitor PD98056, which blocked ERK2 but not JNK1 activation by UV irradiation, impaired UV-driven c-Jun protein induction and AP-1 binding. Based on the data, we suggest that JNK1 stimulation is not essential for transactivation of c-jun after UV exposure, whereas activation of ERK2 is required for UV-induced signaling leading to elevated c-jun expression.  (+info)

The Jun kinase 2 isoform is preferentially required for epidermal growth factor-induced transformation of human A549 lung carcinoma cells. (4/12422)

We have previously found that epidermal growth factor (EGF) mediates growth through the Jun N-terminal kinase/stress-activated kinase (JNK/SAPK) pathway in A549 human lung carcinoma cells. As observed here, EGF treatment also greatly enhances the tumorigenicity of A549 cells, suggesting an important role for JNK in cancer cell growth (F. Bost, R. McKay, N. Dean, and D. Mercola, J. Biol. Chem. 272:33422-33429, 1997). Several isoforms families of JNK, JNK1, JNK2, and JNK3, have been isolated; they arise from alternative splicing of three different genes and have distinct substrate binding properties. Here we have used specific phosphorothioate oligonucleotides targeted against the two major isoforms, JNK1 and JNK2, to discriminate their roles in EGF-induced transformation. Multiple antisense sequences have been screened, and two high-affinity and specific candidates have been identified. Antisense JNK1 eliminated steady-state mRNA and JNK1 protein expression with a 50% effective concentration (EC50) of <0.1 microM but did not alter JNK2 mRNA or protein levels. Conversely, antisense JNK2 specifically eliminated JNK2 steady-state mRNA and protein expression with an EC50 of 0.1 microM. Antisense JNK1 and antisense JNK2 inhibited by 40 and 70%, respectively, EGF-induced total JNK activity, whereas sense and scrambled-sequence control oligonucleotides had no effect. The elimination of mRNA, protein, and JNK activities lasted 48 and 72 h following a single Lipofectin treatment with antisense JNK1 and JNK2, respectively, indicating sufficient duration for examining the impact of specific elimination on the phenotype. Direct proliferation assays demonstrated that antisense JNK2 inhibited EGF-induced doubling of growth as well as the combination of active antisense oligonucleotides did. EGF treatment also induced colony formation in soft agar. This effect was completely inhibited by antisense JNK2 and combined-antisense treatment but not altered by antisense JNK1 alone. These results show that EGF doubles the proliferation (growth in soft agar as well as tumorigenicity in athymic mice) of A549 lung carcinoma cells and that the JNK2 isoform but not JNK1 is utilized for mediating the effects of EGF. This study represents the first demonstration of a cellular phenotype regulated by a JNK isoform family, JNK2.  (+info)

Postnatal growth failure, short life span, and early onset of cellular senescence and subsequent immortalization in mice lacking the xeroderma pigmentosum group G gene. (5/12422)

The xeroderma pigmentosum group G (XP-G) gene (XPG) encodes a structure-specific DNA endonuclease that functions in nucleotide excision repair (NER). XP-G patients show various symptoms, ranging from mild cutaneous abnormalities to severe dermatological impairments. In some cases, patients exhibit growth failure and life-shortening and neurological dysfunctions, which are characteristics of Cockayne syndrome (CS). The known XPG protein function as the 3' nuclease in NER, however, cannot explain the development of CS in certain XP-G patients. To gain an insight into the functions of the XPG protein, we have generated and examined mice lacking xpg (the mouse counterpart of the human XPG gene) alleles. The xpg-deficient mice exhibited postnatal growth failure and underwent premature death. Since XPA-deficient mice, which are totally defective in NER, do not show such symptoms, our data indicate that XPG performs an additional function(s) besides its role in NER. Our in vitro studies showed that primary embryonic fibroblasts isolated from the xpg-deficient mice underwent premature senescence and exhibited the early onset of immortalization and accumulation of p53.  (+info)

The C-terminal region of hPrp8 interacts with the conserved GU dinucleotide at the 5' splice site. (6/12422)

A U5 snRNP protein, hPrp8, forms a UV-induced crosslink with the 5' splice site (5'SS) RNA within splicing complex B assembled in trans- as well as in cis-splicing reactions. Both yeast and human Prp8 interact with the 5'SS, branch site, polypyrimidine tract, and 3'SS during splicing. To begin to define functional domains in Prp8 we have mapped the site of the 5'SS crosslink within the hPrp8 protein. Immunoprecipitation analysis limited the site of crosslink to the C-terminal 5060-kDa segment of hPrp8. In addition, size comparison of the crosslink-containing peptides generated with different proteolytic reagents with the pattern of fragments predicted from the hPrp8 sequence allowed for mapping of the crosslink to a stretch of five amino acids in the C-terminal portion of hPrp8 (positions 1894-1898). The site of the 5'SS:hPrp8 crosslink falls within a segment spanning the previously defined polypyrimidine tract recognition domain in yPrp8, suggesting that an overlapping region of Prp8 may be involved both in the 5'SS and polypyrimidine tract recognition events. In the context of other known interactions of Prp8, these results suggest that this protein may participate in formation of the catalytic center of the spliceosome.  (+info)

Photocrosslinking of 4-thio uracil-containing RNAs supports a side-by-side arrangement of domains 5 and 6 of a group II intron. (7/12422)

Previous studies suggested that domains 5 and 6 (D5 and D6) of group II introns act together in splicing and that the two helical structures probably do not interact by helix stacking. Here, we characterized the major Mg2+ ion- and salt-dependent, long-wave UV light-induced, intramolecular crosslinks formed in 4-thiouridine-containing D56 RNA from intron 5gamma (aI5gamma) of the COXI gene of yeast mtDNA. Four major crosslinks were mapped and found to result from covalent bonds between nucleotides separating D5 from D6 [called J(56)] and residues of D6 near and including the branch nucleotide. These findings are extended by results of similar experiments using 4-thioU containing D56 RNAs from a mutant allele of aI5gamma and from the group IIA intron, aI1. Trans-splicing experiments show that the crosslinked wild-type aI5gamma D56 RNAs are active for both splicing reactions, including some first-step branching. An RNA containing the 3-nt J(56) sequence and D6 of aI5gamma yields one main crosslink that is identical to the most minor of the crosslinks obtained with D56 RNA, but in this case in a cation-independent fashion. We conclude that the interaction between J(56) and D6 is influenced by charge repulsion between the D5 and D6 helix backbones and that high concentrations of cations allow the helices to approach closely under self-splicing conditions. The interaction between J(56) and D6 appears to be a significant factor establishing a side-by-side (i.e., not stacked) orientation of the helices of the two domains.  (+info)

UV irradiation of polycyclic aromatic hydrocarbons in ices: production of alcohols, quinones, and ethers. (8/12422)

Polycyclic aromatic hydrocarbons (PAHs) in water ice were exposed to ultraviolet (UV) radiation under astrophysical conditions, and the products were analyzed by infrared spectroscopy and mass spectrometry. Peripheral carbon atoms were oxidized, producing aromatic alcohols, ketones, and ethers, and reduced, producing partially hydrogenated aromatic hydrocarbons, molecules that account for the interstellar 3.4-micrometer emission feature. These classes of compounds are all present in carbonaceous meteorites. Hydrogen and deuterium atoms exchange readily between the PAHs and the ice, which may explain the deuterium enrichments found in certain meteoritic molecules. This work has important implications for extraterrestrial organics in biogenesis.  (+info)

PDF] Effects of Collagen Peptide Ingestion on UV-B-Induced Skin Damage | Semantic ScholarPDF] Effects of Collagen Peptide Ingestion on UV-B-Induced Skin Damage | Semantic Scholar
The effect of daily ingestion of collagen peptide on the skin damage induced by repeated UV-B irradiation was examined. Ingestion of collagen peptide (0.2 g/kg/d) suppressed UV-B-induced decreases in skin hydration, hyperplasia of the epidermis, and decreases in soluble type I collagen. These results suggest that collagen peptide is beneficial as a dietary supplement to suppress UV-B-induced skin damage and photoaging.

DNA damage can cause cell death unless it is either repaired or tolerated. The precise contributions of repair and tolerance mechanisms to cell survival have not been previously evaluated. Here we have analyzed the cell killing effect of the two major UV light-induced DNA lesions, cyclobutane pyrimidine dimers (CPDs) and 6-4 pyrimidine-pyrimidone photoproducts (6-4PPs), in nucleotide excision repair-deficient human cells by expressing pliotolyase(s) for light-dependent photorepair of either or both lesions. Immediate repair of the less abundant 6-4PPs enhances the survival rate to a similar extent as the immediate repair of CPDs, indicating that a single 6-4PP lesion is severalfold more toxic than a CPD in the cells. Because UV light-induced DNA damage is not repaired at all in nucleotide excision repair-deficient cells, proliferation of these cells after UV light irradiation must be achieved by tolerance of the damage at replication. We found that RNA interference designed to suppress ...

BACKGROUND: Pathogen contamination, causing transfusion-transmitted diseases, is an ongoing concern in transfusion of cellular blood products. In this explorative study, the pathogen-inactivating capacity of UVC irradiation in platelet (PLT) concentrates was investigated. The dose dependencies of inactivation of several viruses and bacteria were compared with the effect on PLT quality.. STUDY DESIGN AND METHODS: The potential of UVC irradiation was studied with a range of lipid-enveloped (LE) and non-lipid-enveloped viruses (NLE) and bacteria. LE viruses were bovine viral diarrhea virus (BVDV), human immunodeficiency virus (HIV), pseudorabies virus (PRV), transmissible gastroenteritis virus (TGEV), and vesicular stomatitis virus (VSV). NLE viruses were canine parvovirus (CPV) and simian virus 40 (SV40). Bacteria were Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, and Bacillus cereus. After spiking and irradiation, samples were tested for residual infectivity and reduction ...

As an attractive dielectric material, polyimide has been widely used in the field of electronics, aerospace, and automobiles due to its useful mechanical properties and good chemical resistance. UV irradiation was considered to be the main factor related to the damage and failure of polyimide. Here the effects of UV irradiation on the surface morphology and microscale mechanical properties of polyimide films are characterized by atomic force microscopy (AFM). The surface roughness of the UV-irradiated samples developed and the mechanical properties degraded with the radiation dose increased. For comparison, uniaxial tensile test was performed to obtain the macroscale Youngs modulus of polyimide film. The UV-irradiated damaging depth was simulated with finite element method (FEM).

There are many things we consider invasive for our skin: chemical products, pollution, stress and even aging are on our list when it comes to things which will badly affect the texture and color of the skin. However, what many people tend to ignore when it comes to their skin is the harmful effect of the sun.. Sun is one of the worst enemies the human skin could have. First of all because there are very few ways in which we can stay out of its way. Everywhere we go we have to meet the dangerous sun rays, especially during the hot days of summer. Because we got so used with it, sun no longer is seen as a threat. Moreover, there are people who benevolently expose their skin to the powerful sun rays without any protection, thus damaging their skin willingly.. But why is sun a threat to human skin after all? Well, the ultraviolet rays which come from the sun are the ones which affect the skin. People with lighter color of skin feel the solar attacks more acutely than people with darker types of ...

The incidence of BCCs increases with age and with no sex predilection.10 However, in our study there were more women than men in all age categories except for those younger than 30 years (one young man affected and no women). The higher presence of women in our study is only partly explained by the demographics in our area.. The spectral sensitivity of the polysulphone film is restricted to wavelengths below 330 nm and consequently measures mainly erythema-producing UVB. The action spectrum for development of BCC is not known. However, the values at the different sites indicate the UVR exposure at that location and there is no reason to believe that different UV wavelengths should be differently distributed.. Sliney11 discussed the difficulties in estimating ocular exposure to UVR. Clearness of the sky, time of the day, time of the year, latitude, altitude, ground reflectance are some of the variables that influence ambient UVR. The fraction of ambient UVR that affects the skin of the eyelids ...

UV radiation causes several forms of DNA damage; the most prominent of these are cyclobutane pyrimidine dimers (CPDs) and 6-4 pyrimidine-photoproducts (6-4 PPs). Nucleotide excision repair (NER) is a repair process that repairs these DNA lesions. Defects in the NER pathway lead to cancer-related diseases such as xeroderma pigmentosum (XP) that is caused by a defect in the XPA to XPG genes that are involved in the NER pathway. To investigate protein recruitment to chromatin after DNA damage, SV40 minichromosomes containing pyrimidine-rich DNA were established to create a tool with high sensitivity to UV for in vivo studies. Using this tool these findings suggest that p54nrb, which exhibits multi-functional characteristics in a variety of cellular processes, including DNA and RNA binding, nuclear RNA processing and regulation of transcription, is a novel protein putatively involved in UV DNA damage response. The objective of this study was to gain a better insight into the mechanism(s) by which ...

What is your opinion on the following postings. This may include asking a clarifying question, highlighting a point of agreement, or professionally identifying a critique of something they stated.. Race is the distinct biological adaptions of an individual that differentiates people groups in society, however, race is not inherently genetic. Due to genetic diversity occurring more within than between, race is still not an accurate way of pinning down a particular genetic code (Jurmain 315). These phenotypic variations, differences that we can visually see (skin color, eye color, body, face, and head shape, etc.), are determined geographically and by the environment. Natural selection played a part in the visual ombré of geographical clines. For example, dark-skinned individuals have adapted to living near the equator where ultraviolet rays are the most intense. Those with light skin live in areas with less exposure to ultraviolet rays. Vitamin D production, stimulated by ultraviolet rays, is ...

Age spots and blemishes are a group of skin-aging pigmented skin diseases that usually appear in faces chronically exposed to ultraviolet rays. Blemishes appear as marks after sudden exposure to the sun, or as dermatitis, folliculitis and external injuries. Age spots, which appear as a phenomenon of skin-aging problems, look uneven mantises or appear as brown, flat, and round specks. They are caused by excessively thickly growing epidermis and deposits of pigment. The ultraviolet rays begin in spring, become strongest in summer and weaken in winter. As a result, freckles and blemishes also seriously appear in spring and summer and may be eased in winter. In addition to getting treatment, it is important to prevent the skin from becoming dark by blocking ultraviolet rays. ...

Few studies in China have examined personal ultraviolet radiation (UVR) exposure using polysulfone dosimetry. In this study, 93 mother and adolescent child pairs (N = 186) from two locations in China, one rural (higher latitude) and one urban (lower latitude), completed 3 days of personal UVR dosimetry and a sun/clothing diary, as part of a larger pilot study. The average daily ambient UVR in each location as measured by dosimetry was 20.24 Minimal Erythemal Doses (MED) in the rural location and 20.53 MED in the urban location. Rural mothers had more average daily time outdoors than urban mothers (5.5 h, compared with 1.5 h, in urban mothers) and a much higher daily average personal UVR exposure (4.50 MED, compared with 0.78 MED in urban mothers). Amongst adolescents, rural males had the highest average daily personal UVR exposure, followed by rural females, urban females and urban males (average 2.16, 1.05, 0.81, and 0.48 MED, respectively).

Ultraviolet Rays Myth and the Ability to Digest Light | Blackseed Diet
Proficiency in the Kemetic language isnt needed to comprehend the message being displayed in the above illustration, it is quite obvious. Clearly, these ancient Africans are telling us here that they understood that the same relationship that the plants have with our Sun is equally shared with us. We cannot separate ourselves from nature, for nature is not just our environment, we are nature itself. If this divine agreement, understanding, and obligation are violated the consequences will be severe, like what we are facing today due to our anti-Sun ways of life. Some people are adversely affected by ultraviolet (UV) rays, while others need them to obtain optimal health. Being affected by something doesnt automatically make it bad for everyone else; neither does it make it bad in general. The human biology is a microcosmic Sun; Melanin (eumelanin) is a physical embodiment of natural light and all of its components, including the ultraviolet range. Contrary to common beliefs, ultraviolet ...

PLANT BREEDING: March 2005PLANT BREEDING: March 2005
Elevated levels of UV-B radiation will have many direct and indirect effects on plants (Fig. 3). Even present-day levels of UV-B radiation affect the growth and development of plants. The direct effects of UV-B radiation on plant cells are mostly damaging, because UV-B photons have enough energy to create lesions in important UV-B-absorbing biomolecules such as nucleic acids and proteins. It is known that the photoproducts of DNA formed by UV-B radiation, cyclobutane pyrimidine dimers and pyrimidine (6-4) pyrimidone and (6-4) photoproducts, are all toxic and mutagenic. In addition, the altered DNA and RNA structures may interfere with transcription and replication; and therefore protein synthesis may be slowed down during UV-B stress. In order to avoid the effects of DNA damage, plants have efficient systems for DNA repair, including photoreactivation and excision repair, which are involved in restoring the structure of genetic material during exposure to UV-B radiation. However, the indirect ...

The aim of the present work was to evaluate the antioxidant and photoprotective effect of blanch water (BW), a byproduct of the almond processing industry. The polyphenolic content of a BW extract, the level of proanthocyanidins and the vanillin index determination were determined. The antioxidant activity and the radical scavenging activity of the BW were evaluated by a range of in vitro tests. The in vivo photoprotective effect was investigated using a formulation containing 2% of the BW extract on skin erythema induced by acute UV-B exposure in twelve volunteers. Results confirmed the presence of added-value antioxidant compounds in the industrial BW extract, and the most representative compounds were naringenin-7-O-glucoside and kaempferol-7-O-rutinoside. The proanthocyanidin content was 71.84 ± 5.21 cyanidin equivalents/g of BW extract. The good antiradical activity of the BW extract was demonstrated in both the DPPH• test and in the Reducing Power test. The percentage inhibition of erythema

Ultraviolet (UV) irradiation kills microorganisms mainly by damaging the microorganisms nucleic acids, but also by affecting their enzymes, amino acids, and the membrane phospholipids. UV wavelength in the range of 200 to 295 nm is the most effective in breaking cellular DNA, thereby destroying the organism. Indeed most UV room disinfection devices use UV-C irradiation which has a characteristic wavelength of 200-270 nm. The efficacy of UV irradiation devices depends on many parameters, such as the organic load present, dose, exposure time, distance of the microorganisms from the device, the device intensity, lamp placement and direct line between the device and the location of the microorganisms. It has been found that double stranded viruses were more resistant than single DNA viruses, and that bacterial and fungal spores are highly resistant to UV inactivation, and photoreactivation has been demonstrated (3). In general, microbes are better inactivated by the UV irradiation when in the air ...

DNA damage-binding protein 2DNA damage-binding protein 2
Required for DNA repair. Binds to DDB1 to form the UV-damaged DNA-binding protein complex (the UV-DDB complex). The UV-DDB complex may recognize UV-induced DNA damage and recruit proteins of the nucleotide excision repair pathway (the NER pathway) to initiate DNA repair. The UV-DDB complex preferentially binds to cyclobutane pyrimidine dimers (CPD), 6-4 photoproducts (6-4 PP), apurinic sites and short mismatches. Also appears to function as the substrate recognition module for the DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex DDB1-CUL4-ROC1 (also known as CUL4-DDB-ROC1 and CUL4-DDB-RBX1). The DDB1-CUL4-ROC1 complex may ubiquitinate histone H2A, histone H3 and histone H4 at sites of UV-induced DNA damage. The ubiquitination of histones may facilitate their removal from the nucleosome and promote subsequent DNA repair. The DDB1-CUL4-ROC1 complex also ubiquitinates XPC, which may enhance DNA-binding by XPC and promote NER. Isoform D1 and isoform D2 inhibit UV-damaged DNA repair ...

Ozone - Digital Library
In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.

N2 - We have exposed confluent normal human fibroblasts to ultraviolet (UV) fluences of 5, 14, or 40 J/m2 and monitored the specific activity of post-UV repair synthesis in chromatin with [3H]thymidine pulses. We have shown that under conditions where no semiconservative deoxyribonucleic acid (DNA) synthesis is detectable, the specific activity of repair label in micrococcal nuclease resistant (core particle) DNA is about one-fifth that in bulk DNA at all three UV fluences. On the other hand, the distribution of thymine-containing pyrimidine dimers in bulk and nuclease-resistant regions measured either immediately after irradiation or at later times showed no significant differences; preferential labeling of linker (nuclease-sensitive) DNA during repair synthesis is thus apparently not due to a predominance of ...

IGF-1 activates p21 to inhibit UV-induced cell death - CSHL Scientific Digital RepositoryIGF-1 activates p21 to inhibit UV-induced cell death - CSHL Scientific Digital Repository
The insulin-like growth factor-1 (IGF-1) and its downstream effector Akt have been documented as survival factors in response to a variety of stress signals. In this study, we show that IGF-1 activates p21 protein expression in a p53-dependent manner. Inhibition of PI-3 kinase or ectopic expression of a dominant-negative Akt blocks the effect of IGF-1 on the upregulation of p21 expression. In addition, IGF-1 prevents the UV irradiation-mediated suppression of p21 and MDM2 expression. Furthermore, p21 is important for IGF-1-mediated cell survival upon UV irradiation. Taken together, these data indicate that IGF-1 may activate p21 in executing its survival function upon genotoxic insults.. ...

UV-B radiation damages nuclear, chloroplast and mitochondrial DNA by the formation of cyclobutane pyrimidine dimers (CPDs), which are the primary UV-B-induced DNA lesions, and are a principal cause of UV-B-induced growth inhibition in plants. Repair of CPDs is therefore essential for plant survival while exposed to UV-B-containing sunlight. Nuclear repair of the UV-B-induced CPDs involves the ...

Sensitivity of Human Skin to Ultraviolet Radiation, Expressed as Minimal Erythema Dose (MED) | CIESensitivity of Human Skin to Ultraviolet Radiation, Expressed as Minimal Erythema Dose (MED) | CIE
Sensitivity of human skin to ultraviolet radiation (UVR) varies dramatically depending on its colour and also varies within each colour band. Yet, public health policies regarding UVR exposure of human skin are mostly based on our knowledge of the UVR effects in only one skin type class: fair-skinned White Caucasians. This report gives a review of the different approaches to predicting and measuring UVR sensitivity using the Minimal Erythema Dose (MED). The MED is defined as the smallest amount of radiation that causes a noticeable reddening of the skin in an individual after a single exposure (evaluated 1 day post-exposure). Ultraviolet radiation is used to diagnose and treat skin conditions in patients with a broad range of complexions (skin colour) from very fair to very dark. Occupational UVR exposures also concern workers representing all types of skin. A sizable proportion of the population in Western countries uses UVR-emitting indoor tanning equipment. Environmental UVR can induce damage ...

Narrowband ultraviolet B exposures maintain vitamin D levels during winter : A randomized controlled trial
Exposure to solar ultraviolet B radiation during the summer months is the main source of vitamin D (VD) for people living in northern latitudes. The aim of this study was to determine whether artificial narrowband ultraviolet B (NB-UVB) whole-body exposures could maintain VD levels in winter. The intervention group received 2 standard erythema doses (SEDs) of NB-UVB exposures every second week from October 2013 to April 2014. In October 2013 serum 25-hydroxyvitamin D concentrations were 78.3 nmol/l in the intervention group (n = 16) and 76.8 nmol/l in the control group (n = 18). By April 2014 the concentrations had increased by 11.7 nmol/l (p = 0.029) in the intervention group and decreased by 11.1 nmol/l (p = 0.022) in the control group. The baseline VD concentration showed a negative correlation (p = 0.012) with body mass index (BMI). In conclusion, a suberythemal NB-UVB dose of 2 SED every second week maintains and even increases serum VD concentrations during the winter. A high BMI seems to ...

UV radiation has been shown to play a role in the initiation of human cutaneous melanoma, but its role in the development of malignant melanoma to the metastatic state is not very well defined. Although previous studies have concentrated on the effect of UV-B on the host immune response, the effect of UV-B on the tumor cells was not elucidated. Here we show that UV-B can induce interleukin 8 (IL-8) mRNA and protein secretion in human cutaneous melanoma with negligible expression of IL-8. UV-B-induced IL-8 was constitutively expressed 60 days after irradiation in tumors implanted in mice. Induction of IL-8 was UV-B dose dependent and blocked by cyclohexamide, indicating that de novo protein synthesis is required for its expression. The UV-irradiated cells demonstrated enhanced tumorigenicity and metastatic potential in nude mice. The increase in tumorigenicity and metastatic ability could be explained by the increase in Mr 72,000 type IV collagenase activity and angiogenesis attributed to the ...

AU - Tyrrell, Rex M.. PY - 1987/10/25. Y1 - 1987/10/25. N2 - We have analyzed the pattern of protein synthesis in solar near ultraviolet (334 nm, 365 nm) and near visible (405 nm) irradiated normal human skin fibroblasts. Two hours after irradiation we find that one major stress protein of approximately 32 kDa is induced in irradiated cells. This protein is not induced by ultraviolet radiation at wavelengths shorter than 334 nm and is not inducible by heat shock treatment of these cells. Although sodium arsenite, diamide, and menadione all induced a 32-kDa protein, they also induced the major heat shock proteins. In contrast, the oxidizing agent, hydrogen peroxide, induced the low molecular weight stress protein without causing induction of the major heat shock proteins. A comparison of the 32-kDa proteins induced by ...

DIGITAL.CSIC: Influence of aerosol multiple scattering of ultraviolet radiation on martian atmospheric sensingDIGITAL.CSIC: Influence of aerosol multiple scattering of ultraviolet radiation on martian atmospheric sensing
The ultraviolet (UV) radiative transfer problem in the martian atmosphere is dominated by multiple scattering of photons with the micron-sized aerosols that are suspended in the thin atmosphere. By implementing a multiple stream, vertical fine layering description of the radiative transfer equation that is able to cope with the strong vertical variations of the atmospheric properties, we estimate the resulting upwelling and downwelling UV irradiances under different martian scenarios in equatorial and close to equatorial latitudes. We include the latest SPICAM measurements on the aerosol vertical profile (distribution of Angstrom exponent and aerosol loading), scattering properties (asymmetry parameter and single scattering albedo), ground albedo, and O3 content as well as MER long-term monitorization of ground-based aerosol optical depth. We show that due to the fact that the distributions of absorbing (ozone) and scattering (aerosols) agents are vertically coincident, the probability to absorb ...

Overexposure to UVB radiation not only can cause sunburn but also some forms of skin cancer. However, the degree of redness and eye irritation (which are largely not caused by UVA) do not predict the long-term effects of UV, although they do mirror the direct damage of DNA by ultraviolet.[51] All bands of UV radiation damage collagen fibers and accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause further damage.[52] UVB radiation can cause direct DNA damage.[53] This cancer connection is one reason for concern about ozone depletion and the ozone hole. The most deadly form of skin cancer, malignant melanoma, is mostly caused by DNA damage independent from UVA radiation. This can be seen from the absence of a direct UV signature mutation in 92% of all melanoma.[54] Occasional overexposure and sunburn are probably greater risk factors for melanoma than long-term moderate exposure.[55] UVC is the highest-energy, most-dangerous type of ultraviolet radiation, and ...

Stress Responses of Peanut (Arachis hypogaea L.) Genotypes as Measured by Trigonelline Content after Exposure to UV-B RadiationStress Responses of Peanut (Arachis hypogaea L.) Genotypes as Measured by Trigonelline Content after Exposure to UV-B Radiation
UV-B radiation has been widely documented as a stressor for plants that can cause decreased biomass, reduction in photosynthesis, and oxidative stress. Trigonelline is a secondary metabolite that is biosynthesized in some plants in response to abiotic stress such as UV-B irradiation. The objectives of this study were to examine biochemical stress responses for peanut plants (Arachis hypogaea L.) of four different genotypes (Spanish, Valencia, Virginia, and Runner) after exposure at various lengths to UV-B radiation and to examine the alteration of trigonelline biosynthesis due to the age of the plants. Peanut plants from the genotypes were exposed to UV-B radiation at three exposure times (60, 120, and 180 min); plants from two growth stages, the flowering (R1) and early maturity (R7), were used. Significant positive correlations (rs 0.29-0.74, P≤0.05) were found for trigonelline concentrations and UV-B exposure times. With longer exposure times of 180 min for plants at R7, trigonelline biosynthesis

Objectives Preventable risk factors for prostate cancer are poorly understood; sun exposure is a possible protective factor. The goal of this study was to investigate prostate cancer risk in outdoor workers, a population with high sun exposure. Methods Prostate cancer cases and controls from a large study (conducted between 1994 and 1997) were used for this analysis. A job exposure matrix ( JEM) was used to assign solar ultraviolet radiation (UVR) at work as moderate (2 to ,6 hours outside/day) or high (≥6 hours). Average daily satellite UV-B measures were linked to the latitude/longitude of the residences of each participant. Several other exposure metrics were also examined, including ever/never exposed and standard erythemal dose by years (SED×years). Logistic regression was used to evaluate the association between solar UVR exposure and the odds of prostate cancer. Results A total of 1638 cases and 1697 controls were included. Men of Indian and Asian descent had reduced odds of prostate ...

Research: UV Radiation, Sunlight | The Elevation of WineResearch: UV Radiation, Sunlight | The Elevation of Wine
Allen, D., S Nogues and N Baker (1998). Review article. Ozone depletion and increased UV-B radiation: is there a real threat to photosynthesis? Journal of Experimental Botany 49(328): 1775- 1788.. This critical review of recent literature questions earlier predictions that photosynthetic productivity of higher plants is vulnerable to increased ultraviolet-B (UV-B) radiation as a result of stratospheric ozone (O3) depletion. Direct UV-B-induced inhibition of photosynthetic competence is observed only at high UV-B irradiances and primarily involves the loss of soluble Calvin cycle enzymes and adaxial stomatal closure in amphistomatous plants. However, even under these extreme UV-B exposures, acclimation (e.g. induction of UV-B absorbing flavonoids) can protect the photosynthetic processes. In plants irradiated with UV-B throughout development a reduction in productivity is usually associated with a reduced ability to intercept light (i.e. smaller leaf area) and not an inhibition of ...

Tendency to Sunburn Easily | Digital Naturopath
Sunburns hurt, and the damage they inflict on your skin is long lasting and dangerous. The redness of a sunburn is caused by clogged and swollen capillaries that supply blood to the skin. Severe burns, caused by the ultraviolet rays in sunlight, damage blood vessels and destroy elastic fibers in the skin, causing it to sag and wrinkle. Excessive sun exposure can also lead to skin cancer, the most common of all cancers.. Prevention is best. Perform outdoor activities before 10:00 A.M. or after 2:00 P.M., when the ultraviolet rays are less intense. Remember to wear a sunscreen with an SPF (sun protection factor) of 15 or higher.. The sun is bad for your skin - or is it? With all the warnings were given about sun exposure, skin cancer, and aging, youd think that God was playing a cruel trick on us by placing that large, warm, inviting ball in the sky. Actually, sunlight - in moderate, regular doses - is good and even mandatory for good health and healthy skin.. We need sunlight for several ...

Effects of UVB irradiation on limbal stem cell niche and its role in cornea lymphangiogenesis | IOVS | ARVO JournalsEffects of UVB irradiation on limbal stem cell niche and its role in cornea lymphangiogenesis | IOVS | ARVO Journals
Purpose: UVB radiation is linked to various ocular pathologies including photokeratitis and pterygium. However the response mechanisms of the limbal epithelial stem cell (LESC) compartment are unclear. Here, the effect of UVB irradiation on the LESC phenotype and the subsequent role of the LESC niche in cornea (lymph)angiogenesis were investigated.. Methods: Primary human limbal epithelial cells (HLE) and fibroblasts (HLF) have been irradiated with 0.02 J/cm2 of UVB. Cell proliferation was tested by using the Alamar Blue assay. The putative LESC phenotype was assessed using the markers P63a, ABCG2, integrin b1 and CK3 (immunophenotyping and QPCR) as well as a colony forming efficiency (CFE) assay. An HLE-HLF co-culture model mimicking the LESC niche was used to compare the ability of irradiated and non-irradiated HLF to support HLE putative LESC phenotype. The levels of angiogenesis-related cytokine and growth factors in conditioned media of irradiated and non-irradiated cells were assessed in a ...

Responses of beech seedlings to supplemental UV-B radiation were investigated during three consecutive seasons, in three repeated experiments. Our attention was paid on the alteration of the photosynthetic pigment composition - especially on the xanthophyll cycle pigments - chlorophyll fluorescence parameters, furthermore the accumulation of UV-B absorbing compounds in leaves, the specific leaf mass and leaf water content. The enhanced UV-B radiation generally affected significantly neither photochemical efficiency of PSII, nor photosynthetic pigment composition. UV-B radiation induced some protective mechanisms, thus VAZ-pool increased in beech leaves in every experiment, parallel with the enhancement of non-photochemical quenching. Amount of UV-B absorbing compounds in leaves increased under enhanced UV-B, but no significant changes were observed in the specific leaf mass. Sensitivity of plants to UV-B is largely influenced by other environmental factors and experimental conditions.. ...

Oral sunscreenOral sunscreen
If theres one thing every skincare expert can agree on, its the importance of slapping on some SPF before you head outside (or even walk by a window). Now, its easier than ever to protect your skin from harmful ultraviolet rays thanks to a relatively new product: oral sunscreen. Oral sunscreens, which typically come in pill form, arent meant to be a complete substitute for the topical version, but they do make a nice addition to your routine. We repeat: DO NOT USE THESE INSTEAD OF TOPICAL SUNSCREEN.. Oral sunscreen agents are typically antioxidants called polypodium leucotomos, said board-certified dermatologist and ethnic skin expert Dr. William Kwan. They may be helpful by increasing the time it takes for a person to burn when exposed to ultraviolet rays..

Ultraviolet (UV) Radiation - Windows to the UniverseUltraviolet (UV) Radiation - Windows to the Universe
Ultraviolet (UV) light is a type of electromagnetic radiation. UV light has a shorter wavelength than visible light. Purple and violet light have shorter wavelengths than other colors of light, and ultraviolet has even shorter waves than violet does; so ultraviolet is sort of purpler-than-purple light or beyond violet light. Ultraviolet radiation lies between visible light and X-rays on the electromagnetic spectrum. UV light has wavelengths between about 380 and 10 nanometers. The wavelength of violet light is around 400 nanometers (or 4,000 ). Ultraviolet radiation oscillates at rates between about 800 terahertz (THz or 1012 hertz) and 30,000 THz.. The ultraviolet spectrum is sometimes subdivided into the near UV (380 to 200 nanometer wavelengths) and extreme UV (200 to 10 nm wavelengths). Normal air is largely opaque to UV with wavelengths shorter than 200 nm (the extreme UV range); oxygen absorbs light in that part of the UV spectrum..

Miscellaneous Sprout EquipmentMiscellaneous Sprout Equipment
Water purification through the use of ultraviolet rays is effectively and rapidly accomplished without the use of heat or chemicals. Special germicidal ultraviolet lamps are utilized to produce short wave radiation lethal to bacteria, viruses, and other microorganism present in common water. Ultraviolet energy at 2,537 angstroms (a measure of wavelength) is required for complete destruction of some microorganisms. The rays created by these lamps are shorter in wavelength than the shortest ultraviolet rays that penetrate the earths atmosphere from the sun. This unique and rapid method of water purification is often used in hospitals, laboratories and veterinaries. Pharmaceutical manufacturers, food processors and bottlers use germicidal lamps to prevent product contamination and, in some instances, for the cold sterilization of the finished product. For commercial sprouting, ultraviolet water purifiers are best utilized in treating incoming water or for water.. ...

We have shown previously that mTORC2 inhibition sensitizes keratinocytes to UVB-induced apoptosis mediated by the transcription factor FOXO3a. FOXO3a is a key regulator of apoptosis and a tumor suppressor in several cancer types. Activation of FOXO3a promotes apoptosis through the coordinated expression of a variety of target genes, including TRAIL and NOXA. We hypothesized that in the setting of mTORC2 inhibition, the UVB-induced expression of these factors would lead to apoptosis in a FOXO3a-dependent manner. Using spontaneously immortalized human keratinocytes (HaCaT cells), we observed that both TRAIL and NOXA expression ...

The physiological mechanisms controlling plant responses to dynamic changes in ambient solar ultraviolet (UV) radiation are not fully understood: this information is important to further comprehend plant adaptation to their natural habitats. We used the fluorimeter Dualex to estimate in vivo the epidermal flavonoid contents by measuring epidermal UV absorbance (A375) in Betula pendula Roth (silver birch) leaves of different ages under altered UV. Seedlings were grown in a greenhouse for 15 days without UV and transferred outdoors under three UV treatments (UV‐0, UV‐A and UV‐A+B) created by three types of plastic film. After 7 and 13 days, Dualex measurements were taken at adaxial and abaxial epidermis of the first three leaves (L1, L2 and L3) of the seedlings.

Every spring for the past two decades, depletion of stratospheric ozone has caused increases in ultraviolet B radiation (UVB, 280-320 nm) reaching Antarctic terrestrial and aquatic habitats. Research efforts to evaluate the impact of this phenomenon have focused on phytoplankton under the assumption that ecosystem effects will most likely originate through reductions in primary productivity; however, phytoplankton do not represent the only significant component in ecosystem response to elevated UVB. Antarctic bacterioplankton are adversely affected by UVB exposure; and invertebrates and fish, particularly early developmental stages that reside in the plankton, are sensitive to UVB. There is little information available on UV responses of larger Antarctic marine animals (e.g., birds, seals and whales). Understanding the balance between direct biological damage and species-specific potentials for UV tolerance (protection and recovery) relative to trophic dynamics and biogeochemical cycling is a ...

MCC is a potential tumor suppressor gene, which is silenced by promoter hypermethylation in a subset of colorectal cancers. However, its functions have remained poorly understood. In the present study, we describe a novel function of MCC in the DNA damage response. Several novel phosphorylation sites were identified by mass spectrometry, including 2 highly conserved ATM/ATR consensus sites at serine 118 and serine 120. In addition, exposure to ultraviolet radiation (UV), but not phleomycin, caused PI3K-dependent phosphorylation of MCC and its nuclear localization. Re-expression of MCC in HCT15 colorectal cancer cells led to a G2/M arrest, and MCC knockdown impaired the induction of a G2/M arrest following UV radiation. Finally, mutation of S118/120 to alanine did not affect MCC nuclear shuttling following UV but did impair MCC G2/M checkpoint activity. Thus, these results suggest that MCC is a novel target of the DNA damage checkpoint and that MCC is required for the complete cell cycle arrest in the G2

Interplay between Transcription and Homologous Recombination in the Presence of DNA DamageInterplay between Transcription and Homologous Recombination in the Presence of DNA Damage
The biochemical processes of DNA repair, replication and recombination compete for the same substrate, the DNA molecule. This competition is natural, as each process requires the same template. In order to resolve possible conflicts between these processes, when they take place on a particular stretch of DNA, certain crosstalk is expected. The complexity is additionally increased by the existence of another DNA dependent process, which occurs in all phases of the cell cycle: transcription.. This thesis aims to investigate the link between transcription inhibition and homologous recombination, especially in the context of UV-induced DNA damage. The results show that the transcription inhibitor 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) induces homologous recombination. The DNA damage caused by UVC irradiation is repaired mainly via nucleotide excision repair, however, it is also known to trigger recombinational repair. In the presence of UV-induced damage, transcription inhibition by ...
