Spider web is being used in India and other countries to promote wound healing. Its ointment at 2.5 and 5% w/w concentrations was tested for wound healing activity in excision and incision wound models in rats. A significant reduction in the area of excision wound was observed for both the treatments when compared to normal healing and control ointment treatments. The period of epithelization f...

Most spider threads are on the micrometre and sub-micrometre scale. Yet, there are some spiders that spin true nano-scale fibres such as the cribellate orb spider, Uloborus plumipes. Here, we analyse the highly specialized capture silk-spinning system of this spider and compare it with the silk extrusion systems of the more standard spider dragline threads. The cribellar silk extrusion system c...

Postmortem proteolysis in skeletal muscle and factors affecting this process were examined in pork, lamb and beef longissimus muscles (LM) to determine the cause of differences in meat tenderness among these species. Fat thickness differed among species in the following order: pork greater than beef greater than lamb. The following patterns were observed for rate of temperature and pH decline: ...

It is well known that age influences organism mobility. This was demonstrated in vertebrates (such as mammals, and birds) but has been less studied in invertebrates with the exception of Drosophila and the nematode Caennorhabditis elegans. Here we studied the influence of age on the mobility of the orb-weaving spider Zygiella x-notata during web construction. The orb-web is a good model because...

Twenty-four women with spider phobia and 45 nonphobic women completed the Disgust Questionnaire (DQ; P. Rozin, A. E. Fallon, & R. Mandell, 1984) and the Spider Phobia Questionnaire (SPQ; R. Klorman, T. C. Weerts, J. E. Hastings, B. G. Melamed, & P. J. Lang, 1974). Participants also underwent behavioral tests concerning disgust sensitivity and fear of spiders. Spider phobic women showed stronger...

People with anxiety or stress-related disorders attend differently to threat-relevant compared with non-threat stimuli, yet the temporal mechanisms of differential allocation of attention are not well understood. We investigated two independent mechanisms of temporal processing of visual threat by comparing spider-phobic and non-fearful participants using a rapid serial visual presentation task...

Temporal visual working memory (VWM) biases in spider anxiety were studied with an Attentional Blink paradigm. In Experiment 1, participants viewed pictures sequentially presented at rates of 80 ms and were instructed to memorize two target pictures. We varied time between targets and valence of the second target (neutral: mushroom, positive: blossom, negative: spider). In Experiment 2, spider ...

Antifungal prophylaxis for patients at high risk for aspergillosis is appealing due to the high morbidity and mortality of aspergillosis despite antifungal therapy (1–3). While voriconazole is a logical option, reports of breakthrough mucormycosis are a cause for concern (5). To identify alternative prophylactic strategies, we utilized our novel, inhalational model of pulmonary Aspergillus fumi...

We have studied the immunological relatedness of LamB proteins from a wide range of enterobacterial species, using antibodies directed against denatured Escherichia coli K12 and Klebsiella pneumoniae LamB proteins (LamBE.c. and LamBK.p., respectively), and anti-peptide antibodies directed against 10 distinct loops of LamB from E. coli K12 predicted to protrude either side of the outer membrane....

Understanding the compatibility between spider silk and conducting materials is essential to advance the use of spider silk in electronic applications. Spider silk is tough, but becomes soft when exposed to water. Here we report a strong affinity of amine-functionalised multi-walled carbon nanotubes for spider silk, with coating assisted by a water and mechanical shear method. The nanotubes adh...
