Catch is a mechanical state occurring in some invertebrate smooth muscles characterized by high force maintenance and resistance to stretch during extremely slow relaxation. During catch, intracellular calcium is near basal concentration and myosin crossbridge cyctng rate is extremely slow. Catch force is relaxed by a protein kinase A-mediated phosphorylation of sites near the N- and C- temini ...

BACKGROUND AND PURPOSE The purpose of the study was to compare efficacy and potential complications of 2 commercially available devices for mechanical thromboembolectomy. METHODS Devices were tested in an established animal model allowing the use of routine angiography catheters and thrombectomy devices. Radio-opaque thrombi were used for visualization of thrombus-device interaction during an...

Baltic seals are recovering after a population decline. The increasing seal stocks cause notable damage to fisheries in the Baltic Sea, with an unknown number of seals drowning in fishing gear every year. Thus, sustainable seal management requires updated knowledge of the by-catch of seals--the number of specimens that die in fishing gear. We analyse the by-catch of grey seals (Halichoerus gryp...

The shrimp fishery is the most economically important fishery in Mexico. The trawler-based portion of this fishery results in high rates of by-catch. This study quantifies and describes the biodiversity of by-catch associated with trawling in the Bahía de Kino region of Sonora, Mexico. Data were collected from 55 trawls, on six boats, over 14 nights, during November of 2003, 2004, 2006-2009. By...

The relationship between annual water level of Danube and annual catches of Pontic shad (Alosa immaculata, Bennett 1835) in Romania were analyzed. For analysis of long term data on the Danube water level and Pontic shad catch (1920-2013), combinations of different methods were applied using programs Statistica, SPSS 13.0 and MATLAB 6. Periodograms, containing cyclic patterns, were obtained usin...

This paper explores whether Ethiopia's rapid economic growth is transformative enough for the country to eventually catch up with high-income countries. It does so by exploring change and continuity of four elements social capability from 1950 2020: structural transformation, inclusion state's autonomy accountability. finds that modestly strengthened until mid-1970s, then weakened early 2000s, ...
