Commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only. Bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation, or if the distribution of valuations is very peaked around the mean. ∗This note unbundles results previously provi...

introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...

conclusions alterations were present in both the aspect and spacing of collagen fibrils and in the shape of elastic fibers. the present familial combination of scad and edsh, with almost similar ultrastructural features suggests a possible connection between both conditions. case presentation we present a woman with scad and her five close relatives showing obvious or suggestive signs of edsh. ...

combination formulations of liposomes with collagen have been previously introduced as a means of obtaining more stable and less permeable liposomes. in this study, the effect of aqueous solutions of the collagen products collapur? (col) and collapuron-dak? (cold) from henkle co., on the release rate of sodium chromate (chr) as a water-soluble model drug from stable plurilamellar vesicles (splv...

tendons are frequently targets of injury in sports and work. whether nonsteroidal anti-inflammatory drugs (nsaids) have beneficial effects on tendon healing is still a matter of debate. this study was conducted to evaluate effects of flunixin meglumine (fm) on tendon healing after experimentally induced acute trauma. twenty eight adult male new zealand white rabbits were subjected to complete t...

nicotine is one the chemical substance with high level of toxically. it crosses the placenta and accumulates in the developing organs of fetus. our previous investigations indicated that collagen type iv plays a key role in basement membrane of various embryonic organs. in this study we evaluated the effect of maternal nicotine exposure pre and postnatal period on collagen iv expression during ...

objective(s):skin extracellular matrix, which contains type i and type iii collagens, is involved in skin development. the aim of this study was to investigate type iii collagen distribution pattern as well as its changes during pre and post-natal skin morphogenesis in rats. materials and methods: ventral skins of wistar rat embryos at different stages from 10 to 20 gestational day (e10-e20) an...

Radiofrequency catheter ablation uses programmed electrical stimulation to alter or destroy cells causing irregular parenchymal activity. Despite its history of clinical adoption across a range therapeutic areas, the 3D volume ablated tissue has yet be quantified. To address this gap, we developed novel Serial Two-Photon Plus (STP2) pipeline visualize and quantify through imaging sub-micron cel...
