Butterflies are believed to use mainly visual cues when searching for food and oviposition sites despite that their olfactory system is morphologically similar to their nocturnal relatives, the moths. The olfactory ability in butterflies has, however, not been thoroughly investigated. Therefore, we performed the first study of odour representation in the primary olfactory centre, the antennal l...
BACKGROUND The common stinging nettle, Urtica dioica L. sensu lato, is an invertebrate "superhost", its clonal patches maintaining large populations of insects and molluscs. It is extremely widespread in Europe and highly variable, and two ploidy levels (diploid and tetraploid) are known. However, geographical patterns in cytotype variation require further study. NEW INFORMATION We assembled ...
The aims of the present study were to investigate the effect of Gokshura and nettle root extracts on growth rate and sex reversal in Convict cichlid fish. Seven-day hatchlings were immersed in water containing 0 (Control, T1), 200 mg/l nettle root extract (T2), 300 mg/l nettle root extract (T3), 10 mg/l Gokshura extract (T4) and 10 mg/l Gokshura plus 200 mg/l nettle root extracts (T5) for two m...
Acne is a cutaneous pleomorphic disorder of the pilosebaceous unit involving abnormalities in sebum production and is characterized by both inflammatory (papules, pustules and nodules) and no inflammatory (comedones, open and closed) lesions. Propionibacterium acnes and Staphylococcus epidermidis are common pus-forming microbes responsible for the development of various forms of, acne vulgaris....
A study was designed to evaluate the frequency of complementary/alternative therapy (CAM) knowledge and usage in cancer patients. A 23-item survey questionnaire was administered to 494 patients who received chemotherapy in the medical oncology department of three hospitals between June 2011 and December 2011. After giving written informed consent, patients completed a selfadministered questionn...
Despite the intensive research on plant chitinases, largely bolstered by their antifungal properties, little is known at present about the structure-activity relationships of these enzymes. Here we report the identification of essential active site residues in endochitinase Ch3, a class I enzyme abundant in chestnut seeds. Knowledge-based protein modeling as well as structural and sequence comp...
We describe a language-centric approach to solving the complex, low-level, and error-prone nature of network control. Specifically, we have designed a domain-specific language called Nettle, embedded in Haskell, that allows programming OpenFlow networks in an elegant, declarative style. Nettle is designed in layers to accommodate a family of DSLs targeted for specific network applications. The ...
Abstract Understanding metal plant availability as influenced by soil conditions is of key importance for phytoremediation research and for quantification of environmental risk assessment in polluted areas. Urtica dioica L. was chosen as study object as it is omnipresent in the temperate climate region and in the area under study in particular. The study area stretched over 630 km2 in Flanders,...
