In the Tajik National Park (TNP) - a high-altitude area of nearly 26,000 km2 in Central Asia - past and present human activities visibly contrast with standard conservation requirements for protected areas worldwide. This paper focuses on resource management, and highlights three major processes that threaten both the sustainable use of natural resources and the preservation of nature per se: (i) intensified use of biomass as a fuel resource, (ii) inappropriate pasture management, and (iii) increased pressure on endangered wildlife. From analysis of these processes - their historical background, root causes, trends and interrelationships - options and needs to improve park management are proposed and discussed.

Background Complementary medicine (CM) is popular in Switzerland. Several CM methods (traditional Chinese medicine/acupuncture, homeopathy, anthroposophic medicine, neural therapy, and herbal medicine) are currently covered by the mandatory basic health insurance when performed by a certified physician. Treatments by non-medical therapists are partially covered by a supplemental and optional health insurance. In this study, we investigated the frequency of CM use including the evolvement over time, the most popular methods, and the user profile. Methods Data of the Swiss Health Surveys 2007 and 2012 were used. In 2007 and 2012, a population of 14,432 and 18,357, respectively, aged 15 years or older answered the written questionnaire. A set of questions queried about the frequency of use of various CM methods within the last 12 months before the survey. Proportions of usage and 95% confidence intervals were calculated for these methods and CM in general. Users and non-users of CM were compared using logistic regression models. Results The most popular methods in 2012 were homeopathy, naturopathy, osteopathy, herbal medicine, and acupuncture. The average number of treatments within the 12 months preceding the survey ranged from 3 for homeopathy to 6 for acupuncture. 25.0% of the population at the age of 15 and older had used at least one CM method in the previous 12 months. People with a chronic illness or a poor self-perceived health status were more likely to use CM. Similar to other countries, women, people of middle age, and those with higher education were more likely to use CM. 59.9% of the adult population had a supplemental health insurance that partly covered CM treatments. Conclusions Usage of CM in Switzerland remained unchanged between 2007 and 2012. The user profile in Switzerland was similar to other countries, such as Germany, United Kingdom, United States or Australia.

Background: Recombinant allergens are preferred over natural allergen extracts in measuring antibodies. We tested the use of recombinant variants of the major mouse allergen Mus m 1 in detection of mouse-specific antibodies in sera of laboratory animal workers and children. Methods: Six recombinant major urinary proteins (MUPs) were produced and antibody-binding capacity was compared to natural Mus m 1 and to mouse urine extract. In a specific subset, cross-reactivity of MUP with Mus m 1 and between the different recombinant MUPs was determined. Results: For IgE antibodies, MUP8 showed high cross-reactivity with Mus m 1. MUP8-specific IgE was found in 55% of the mouse urine IgE-positive sera. Specific IgG and IgG4 antibodies against natural Mus m 1 correlated strongly with antibodies against recombinant MUP8 and were cross-reactive. IgG4 levels against MUP8 and mouse urine extract correlated, but detection of mouse urine-specific IgG4 in the absence of MUP-specific IgG4 was not uncommon. Cross-reactivity of IgG antibodies between MUP8 and Mus m 1 as well as between the different MUPs was high and inhibition varied between 54 and 99%. Conclusion: The mouse allergen Mus m 1 can be replaced in antibody testing by recombinant MUP8. Other MUPs, except MUP4, are interchangeable with MUP8. However, mouse urine extract showed better detection of both mouse-specific IgE and IgG4 levels. Other components in the mouse urine, like mouse albumin and other yet unidentified components, also induce IgE and IgG(4) antibodies.

Traditionally, keratinocytes have been considered inert constituents of the multilayered epidermis. Today's understanding has fundamentally changed. The keratinocyte is now recognized as an active player in epidermal renewal with key functions in the skin's immune defence. Under homeostatic conditions, keratinocyte progenitor cells are believed to divide symmetrically or asymmetrically, that is they continue to proliferate or go on to terminally differentiate and build up the overlaying epidermis. The fine-tuned process of epidermal renewal relies on an extraordinary network of signalling cascades which are governed by keratinocyte-receptor interactions with the environment through paracrine and autocrine circuits. Opposing this coordinated homeostatic process are signals of wounding and inflammation. They alter the fate of the keratinocyte and its response to the environment through changes in adhesion molecules and surface receptors, in addition to triggering an immediate inflammatory keratinocyte response in terms of secretion of cytokines, chemokines and antimicrobial peptides. If uncontrolled, the fundamental changes imposed by wounding and inflammation upon the homeostatic programme can lead to severe skin lesions including chronic inflammatory disorders. This review will describe the current knowledge of the regulatory signalling network which allows the keratinocyte to actively impact both epidermal homeostasis and the inflammatory response.
