A novel papillomavirus was cloned from hyperkeratotic cutaneous lesions of a Persian domestic cat. The Felis domesticus papillomavirus (FdPV-1) genome counts 8300 bp and has a typical genome structure with an early region (E1, E2, E4, E6, E7), a late region (L1, L2), and a noncoding upstream regulatory region (URR or NCR1) between the end of L1 and the beginning of E6. The FdPV-1 also shows an unusual second noncoding region (NCR2) of 1.3 kb, situated between the end of E2 and the beginning of L2. This NCR2 is uniquely related to a similar region in the canine oral papillomavirus (COPV). Phylogenetic analysis places FdPV-1 together with COPV, the cottontail rabbit papillomavirus, human papillomavirus type 1 (HPV-1), and HPV-63 in the group of the benign cutaneous papillomaviruses. The position of FdPV-1 in the phylogenetic tree allows us to hypothesize that already in an early phase of the papillomavirus molecular evolution, a split occurred into viruses with a dual tropism primarily for cutaneous epithelia but also secondarily for mucosal surfaces, and viruses with a specific monotropism for mucosal surfaces. The close relationship between FdPV-1 and COPV, and between their Canidae and Felidae hosts, supports the hypothesis that papillomaviruses have speciated and coevolved together with their hosts throughout vertebrate evolution. A papillomavirus mutation rate of 0.73 to 0.96 x 10(-8) nucleotide substitutions per base per year was calculated. 相似文献

Macrophages play essential roles in infection and resolution of inflammation. This review summarizes recent findings that suggest a relevant role for the nuclear receptor liver X receptor (LXR) in the evolution of immune responses. By exerting both positive and negative regulation of specific macrophage gene expression networks, LXRs display anti-inflammatory activities and promote macrophage survival in bacterial infection settings. Agonists that activate the LXR pathway may be used to enhance innate immunity to highly virulent pathogens that otherwise induce macrophage apoptosis as a means to subvert host immune defense. 相似文献

Background and Aims: Work plays an important role in adults' well-being, irrespective of health status. Vocational rehabilitation can enable people with mental illness to return to open employment. A narrative approach was used to explore how individuals with a mental illness made sense of their work-related experiences.
Methods and Results: Four Clubhouse members in open employment for at least 6 months completed in-depth, semistructured interviews, from which narratives were created to reveal events, significant persons and actions that assisted these individuals to resume work. Woven into the participants' stories were four 'impelling forces' contributing to a sense-of-self as a worker. These impelling forces were: support from significant others, the personal meaning of work, experiences within the Clubhouse programme, and the ongoing struggle with illness. Implications for occupational therapy practice are discussed.
Conclusion: The findings of this study urge occupational therapists and others to provide opportunities to provide on-going support to people with a mental illness who seek paid employment. 相似文献

Background: The Perceived Need for Care Questionnaire (PNCQ) was designed for the Australian National Survey of Mental Health and Wellbeing.
The PNCQ complemented collection of data on diagnosis and disability with the survey participants' perceptions of their needs
for mental health care and the meeting of those needs. The four-stage design of the PNCQ mimics a conversational exploration
of the topic of perceived needs. Five categories of perceived need are each assigned to one of four levels of perceived need
(no need, unmet need, partially met need and met need). For unmet need and partially met need, information on barriers to
care is collected. Methods: Inter-rater reliabilities of perceived needs assessed by the PNCQ were examined in a study of 145 anxiety clinic attenders.
Construct validity of these items was tested, using a multi-trait multi-method approach and hypotheses regarding extreme groups,
in a study with a sample of 51 general practice and community psychiatric service patients. Results: The instrument is brief to administer and has proved feasible for use in various settings. Inter-rater reliabilities for
major categories, measured by the kappa statistic, exceeded 0.60 in most cases; for the summary category of all perceived
needs, inter-rater reliability was 0.62. The multi-trait multi-method approach lent support to the construct validity of the
instrument, as did findings in extreme groups. Conclusions: The PNCQ shows acceptable feasibility, reliability and validity, adding to the range of assessment tools available for epidemiological
and health services research.

Building workforce capacity for ethical reflection in health promotion: a practitioner's experience

Health promotion does not have a code of ethics, although attempts have been made to assist practitioners in their understanding and application of ethical concepts. This article describes and analyses one such attempt, sustained from 2006 to 2014 in rural South Australia. The attempt comprised capacity‐building activities that were informed by principles of organisational change management, especially the principle of creating champions. The article also presents a framework (largely comprising ethical questions) that may help practitioners as a prompt and guide to ethical reflection. The framework was developed to be as accessible as possible in light of the diverse educational backgrounds found in rural settings. Finally, the article highlights some philosophical dimensions to the framework and defends its role, proposing that ethical reflection is integral to good practice and never simply the province of theorists. The article does all this with a view to stimulating discussion on how to increase the frequency and quality of ethical reflection undertaken by health promotion practitioners. 相似文献
