About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). By using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the dynamic maximum economic yield (MEY), the biomass that produces ...
PURPOSE Characteristic hypoglycemia, hypotriglyceridemia, hypocholesterolemia, lower body mass, and fat as well as pronounced insulin-sensitivity of RLIP76⁻/⁻ mice suggested to us the possibility that elevation of RLIP76 in response to stress could itself elicit metabolic syndrome (MSy). Indeed, if it were required for MSy, drugs used to treat MSy should have no effect on RLIP76⁻/⁻ mice. RESE...
Y chromosome deletions arise frequently in human populations, where they cause sex reversal and Turner syndrome and predispose individuals to infertility and germ cell cancer. Knowledge of the nucleotide sequence of the male-specific region of the Y chromosome (MSY) makes it possible to precisely demarcate such deletions and the repertoires of genes lost, offering insights into mechanisms of de...
Many studies of human populations have used the male-specific region of the Y chromosome (MSY) as a marker, but MSY sequence variants have traditionally been subject to ascertainment bias. Also, dating of haplogroups has relied on Y-specific short tandem repeats (STRs), involving problems of mutation rate choice, and possible long-term mutation saturation. Next-generation sequencing can ascerta...
The major goal of the Chromosome-Centric Human Proteome Project (C-HPP) is to systematically map the entire human proteome with the intent to enhance our understanding of human biology at the cellular level. However, this goal may be hindered by the lack of quality observations of given proteins due to absence of expression in a given tissue, very low abundance, and expression only in rare samp...
In this paper, maximum sustainable yield policy in prey-predator system is discussed where the prey population follows logistic law of growth. Here a model is proposed involving linear prey–predator interaction and intra-specific competition among predator populations. The growth rate of the predator depends upon predation on the modelled and alternate prey. In traditional prey–predator system,...
Mesoporous high-silica zeolite Y with advantages of improved accessibility acid sites and mass transport properties is highly desired catalytic materials for oil refinery, fine chemistry emerging biorefinery. Here, we report the direct synthesis mesoporous (named MSY, SiO2/Al2O3 ? 9.8) their excellent cracking performance. The obtained MSY are single crystals octahedral morphology, abundant mes...
The focus of this article is to investigate the biological reference points, such as the maximum sustainable yield (MSY), in a common Schaefer (logistic) surplus production model in the presence of a multiplicative environmental noise. This type of model is used in fisheries stock assessment as a first-hand tool for biomass modelling. Under the assumption that catches are proportional to the bi...
INTRODUCTION In this article are demonstrated differences in the aspects of the metabolic syndrome (MSy) between genders, as well as the association of MSy and neuropathy. THE AIM The aim of our study was that in patients with newly discovered metabolic syndrome of both sexes make comparison of fasting blood glucose levels and after oral glucose tolerance test, as well as neurophysiological p...
The massive green tide blooms caused by macroalgae Ulva in the Southern Yellow Sea, China, threaten local fish populations. However, tides are not factored into determination of sustainable fisheries targets, which hinders achievement maximum yield (MSY). Using a fishery as case study we highlighted need to redefine MSY-based targets face tides. We modeled natural mortality events and evaluated...
