OBJECTIVE: To investigate Australian adults' awareness of the ultraviolet (UV) indexes forecast in the media, and whether these UV forecasts influence their behaviour in the sun. METHODS: A self-administered questionnaire was used on two occasions in 1997 to ask about knowledge of UV indexes shown in the media and about possible influence on outdoor behaviour. SETTING AND PARTICIPANTS: Participants were 977 residents (423 men; 554 women) of Nambour originally randomly selected in 1986 from the electoral roll, who have been followed up subsequently. RESULTS: The majority of people--92% of men and 86% of women--reported having seen or heard the UV indexes forecast during summer. Of these, significantly fewer men (107; 28%) than women (209; 46%) reported that their outdoor behaviour was influenced by knowledge of the forecast (p = 0.001). Neither age nor skin type, nor history of sunburns or skin cancer, affected knowledge of UV forecasts or their influence on behaviour. CONCLUSIONS AND IMPLICATIONS: Although most people are aware of the forecasts of UV indexes in the media, the majority do not take them into account in their outdoor behaviour. Compared with women, men were more aware of, but less influenced by, forecasts of UV indexes. Better communication of the implications of the UV indexes is needed, particularly to men, if they are to adapt their outdoor behaviour to improve their sun protection. 相似文献

· Background: Acute follicular conjunctivitis is a clinical diagnosis common to multiple etiologies, of which chlamydial infection
requires specific antibiotic treatment. · Purpose: This prospective study was designed to evaluate Chlamydia trachomatis as the cause of acute follicular conjunctivitis by two sensitive tests: direct enzyme-linked immunosorbent assay (ELISA)
and polymerase chain reaction (PCR). · Methods: Conjunctival scrapings from patients presented with untreated acute follicular
conjunctivitis were examined by ELISA and PCR, and patients were followed up for prolongation of the disease course. · Results:
All 36 consecutive patients presented with acute follicular conjunctivitis were negative for Chlamydia trachomatis by ELISA and PCR. None of the patients had a prolonged course of more than 4 weeks or required treatment with systemic antibiotics
as would be expected from chlamydial infection. · Conclusions: Chlamydia trachomatis was probably not responsible for the acute follicular conjunctivitis in this series, and ELISA and PCR may not be cost effective
for evaluation of acute follicular conjunctivitis due to chlamydial infection. Further evaluation of the cost effectiveness
of these tests is required in chronic follicular conjunctivitis.

Characterization of Powassan viruses from Far Eastern Russia 总被引:1,自引:0,他引:1
Galina N. Leonova Ilia G. Kondratov Vladimir A. Ternovoi Elena V. Romanova Elena V. Protopopova Eugene V. Chausov Elena V. Pavlenko Elena I. Ryabchikova Sergey I. Belikov Valery B. Loktev 《Archives of virology》2009,154(5):811-820
We report the isolation and detailed characterization of the novel strain, Partizansk/2006, of Powassan virus (POWV) from
a human case of infection, which occurred in Primorsky krai, Russia, in 2006. Comparative complete genome sequence analysis
of the Far Eastern strains Spassk-9 (1975), Nadezdinsk-1991 and Partizansk/2006 of POWV revealed that these strains are 99.8%
similar to the LB strain, which was isolated in Canada in 1958. Phylogenetic analysis of 5′ UTR sequences of five other strains
of POWV isolated from 1972 to 1986 in Primorsky krai produced similar results. Presumably, Far Eastern POWV has common putative
ancestor with LB strain POWV from North America, and the time of divergence of these POWVs is relatively short. We conclude
that POWV has become endemic in Far Eastern Russia. 相似文献

Release of ATP in the central nervous system during systemic inflammation: real-time measurement in the hypothalamus of conscious rabbits 总被引:1,自引:0,他引:1

Receptors for extracellular ATP (both ionotropic and metabotropic) are widely expressed in the CNS both in neurones and glia. ATP can modulate neuronal activity in many parts of the brain and contributes to the central nervous control of several physiological functions. Here we show that during the systemic inflammatory response the extracellular concentrations of ATP increase in the anterior hypothalamus and this has a profound effect on the development of the thermoregulatory febrile response. In conscious rabbits we measured ATP release in real time with novel amperometric biosensors and monitored a marked increase in the concentration of ATP (4.0 ± 0.7 μ m ) in the anterior hypothalamus in response to intravenous injection of bacterial endotoxin – lipopolysaccharide (LPS). No ATP release was observed in the posterior hypothalamus. The release of ATP coincided with the development of the initial phase of the febrile response, starting 18 ± 2 min and reaching its peak 45 ± 2 min after LPS injection. Application of the ATP receptor antagonists pyridoxal-5'-phosphate-6-azophenyl-2',4'-disulphonic acid, Brilliant Blue G or periodate oxidized ATP dialdehyde to the site of ATP release in the anterior hypothalamus markedly augmented and prolonged the febrile response. These data indicate that during the development of the systemic inflammation, ATP is released in the anterior hypothalamus to limit the magnitude and duration of fever. This release may also have a profound effect on the hypothalamic control of other physiological functions in which ATP and related purines have been implicated to play modulatory roles, such as food intake, hormone secretion, cardiovascular activity and sleep. 相似文献
