Bumblebees (B. terrestris) were trained to fly through an experimental setup containing two tunnels which led to a single feeder. A variety of patterns were fitted onto the tunnel walls, each producing a different pattern of optic flow onto the retinae, in order to test for differences in flight behaviour and decision making as a response to the visual cues presented in the tunnels. The results sh
As chaperones, heat shock proteins (HSPs)protect host cells against misfolded proteins that constitute a by-product of protein synthesis. Certain HSPs are also expressed on the surface of tumor cells, possibly to scavenge extracellular unfolded protein ligands and prevent them from becoming cytotoxic. HAMLET—a complex of partially unfolded alpha-lactalbumin and oleic acid—is relying on its N-termi
Based on their review of abstracts submitted to the German Cardiac Society, Boehm et al. (2014) report better success of female vs male cardiologists publishing in journals with an impact factor ≥5. However, only 25% of conference abstracts were submitted by women, perhaps suggesting a paucity of women in academic cardiology. In this 'letter to the editor' we review gender statistics in the medica
The effect of strain and transforming growth factor beta on equine tendon fibroblasts (tenocytes) was assessed in vitro. Tenocytes were isolated from flexor and extensor tendons of horses from foetal to 10 years of age. These cells were cultured until confluent on collagen-coated silicone dishes. Cyclic biaxial strain of 9 +/- 1% was applied at 0.5 Hz for 24 hours with or without added TGFbeta1 or
A generalized equation for cell survival or tissue effects after fractionated low dose-rate irradiations, when there is incomplete repair between fractions and significant repair during fractions, is derived in terms of the h- and g-functions of the 'incomplete-repair' (IR) model. This model was developed originally from the concept of 'dose equivalent of incomplete repair', assuming that the repa
During the last decade there has been an ongoing controversy regarding the extent to which nitrogen fertilization can increase carbon sequestration and net ecosystem production in forest ecosystems. The debate is complicated by the fact that increased nitrogen availability caused by nitrogen deposition has coincided with increasing atmospheric carbon dioxide concentrations. The latter could furthe

Background and Objectives. Thalidomide modulates the production of tumor necrosis factor (TNF-alpha). Soluble TNF receptors, TNFR p55 and TNFR p75, modify TNF-a activity. In this study, we explored the relation between soluble TNF receptors and outcome in patients with advanced multiple myeloma treated with thalidomide. Design and Methods. The levels of soluble TNF receptor p55 and p75 were assess
OBJECTIVES: To study bowel ischaemia in transfemorally placed endoluminal grafting (TPEG) for abdominal aortic aneurysms, and any relation to cytokine response or postoperative fever. DESIGN: Prospective not randomised. University hospital setting. MATERIAL: Fourteen cases of conventional surgery and 23 cases of endovascular technique for infrarenal abdominal aortic aneurysm repair. METHODS: Tonom
The present study is included in a project with the aim to develop attractants from food odors for trapping female moths. Males and mated, but not unmated, females of Ephestia cautella and Plodia interpunctella were attracted by odors of three different chocolate products in flight tunnel experiments. Chocolate containing nut or rum elicited upwind flight and landing responses. Extracts of the cho
Both abundant epidermal growth factor receptor (EGFR or ErbB1) and high activity of the phosphatidylinositol 3-kinase (PI3K)-Akt pathway are common and therapeutically targeted in triple-negative breast cancer (TNBC). However, activation of another EGFR family member [human epidermal growth factor receptor 3 (HER3) (or ErbB3)] may limit the antitumor effects of these drugs. We found that TNBC cell
