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 ...

The appropriateness of paraphrases for words depends often on context: “grab” can replace “catch” in “catch a ball”, but not in “catch a cold”. Structured Vector Space (SVS) (Erk and Padó, 2008) is a model that computes word meaning in context in order to assess the appropriateness of such paraphrases. This paper investigates “best-practice” parameter settings for SVS, and it presents a method ...

This study examined trends along a gradient of fishing intensity in an artisanal coral reef fishery over a 10-year period along 75 km of Kenya's most populated coastline. As predicted by Malthusian scenarios, catch per unit effort (CPUE), mean trophic level, the functional diversity of fished taxa, and the diversity of gear declined, while total annual catch and catch variability increased alon...

In commercial and recreational fisheries, catch rate is often assumed to be proportional stock size used by managers fishers as an indicator of fishery sustainability. If size, it can signal a decline stocks impose restrictive harvest policies or anglers move new system allow the over-exploited rebound. A growing literature has documented rates remaining high even fish (i.e., hyperstability rat...

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 ClpXP protease of bacteria can degrade a wide variety of proteins while maintaining remarkable substrate selectivity. New work in Escherichia coli implicates adaptor proteins in enhancing substrate selectivity and regulating the flow of substrates to cellular proteases.

Catch-up growth early in life (after fetal, neonatal or infantile growth retardation) is a major risk factor for later obesity, type-2 diabetes and cardiovascular diseases. These risks are generally interpreted alongside teleological arguments that environmental exposures which hinder growth early in life lead to programming of 'thrifty mechanisms' that are adaptive during the period of limited...
