Abstract
Harnessing the economic potential of the oceans is key to combating poverty, enhancing food security, and strengthening economies. But the concomitant risk of intensified resource extraction to migratory species is worrying given these species contribute to important ecological processes, often underpin alternative livelihoods, and are mostly already threatened. We thus sought to quantify the potential conflict between key economic activities (5 fisheries and hydrocarbon exploitation) and sea turtle migration corridors in a region with rapid economic development: southern and eastern Africa. We satellite tracked the movement of 20 loggerhead (Caretta caretta) and 14 leatherback (Dermochelys coriacea) turtles during their postnesting migrations. We used movement-based kernel density estimation to identify migration corridors for each species. We overlaid these corridors on maps of the distribution and intensity of economic activities, quantified the extent of overlap and threat posed by each activity on each species, and compared the effects of activities. These results were compared with annual bycatch rates in the respective fisheries. Both species' 3 corridors overlapped most with longline fishing, but the effect was worse for leatherbacks: their bycatch rates of approximately 1500/year were substantial relative to the regional population size of <100 nesting females/annum. This bycatch rate is likely slowing population growth. Artisanal fisheries may be of greater concern for loggerheads than for leatherbacks, but the population appears to be withstanding the high bycatch rates because it is increasing exponentially. The hydrocarbon industry currently has a moderately low impact on both species, but mining in key areas (e.g., Southern Mozambique) may undermine >50 years of conservation, potentially affecting >80% of loggerheads, 33% of the (critically endangered) leatherbacks, and their nesting beaches. We support establishing blue economies (i.e., generating wealth from the ocean), but oceans need to be carefully zoned and responsibly managed in both space and time to achieve economic (resource extraction), ecological (conservation, maintenance of processes), and social (maintenance of alternative livelihood opportunities, alleviate poverty) objectives.

Abstract
In a previous study, it was shown that a combined treatment of hyperthyroidism and hindlimb suspension effectively converted the slow-twitch soleus muscle to a fast-twitch muscle. The objective of this study was to test the hypothesis that hypothyroidism [absence of triiodothyronine (-T(3))] and mechanical overload (OV) would convert the plantaris (Plan) muscle from a fast- to a slow-twitch muscle. Single-fiber analyses demonstrated that the normal rodent Plan muscle was composed of approximately 13 different fiber types as defined by myosin heavy chain (MHC) isoform content. The largest proportion of fibers ( approximately 35%) coexpressed the fast type IIX and IIB MHC isoforms (i.e., type IIX/IIB fibers). In this context, the combined intervention of -T(3) and OV produced a significant reduction in the relative proportion of the fast type IIB MHC isoform and a concomitant increase in the slow type I MHC isoform. These transitions were manifested by a large decrease in the proportion of type IIX/IIB fibers and a large increase in fibers coexpressing all four MHC protein isoforms. The mechanical consequences of these transitions, however, were modest, producing a 15% decrease in maximal shortening velocity. The findings of this study demonstrate that -T(3) + OV does produce a partial shift toward a slower phenotype; however, the high degree of polymorphism found in the Plan muscle represents a unique design that appears to minimize the functional consequences of these significant MHC transitions.

Abstract
Preterm infants are not physiologically or developmentally prepared for life outside the supportive environment of the mother's womb. Their response to stimuli is often immature and disorganized rather than adaptive. The Roy Adaptation Model's theory of an adaptive person may provide a framework for nurses to assess, plan, and evaluate nursing care for fragile preterm infants. The article examines actual and potential stressors of the premature infant; describes commonly observed disorganized, ineffective responses; and proposes a clinical tool (the STRESS tool: signs of stress, touch interventions, reduction of pain, environmental considerations, state, and stability) that nurses can use when caring for medically fragile infants.

Abstract
The purpose of this study was to determine the effects of a novel combination of mechanical activity paradigms on the isomyosin distribution in rat hindlimb muscles. Thirty female Sprague-Dawley rats were divided into five experimental groups as follows: normal control, functional overload (OV) of the plantaris, OV in conjunction with hindlimb suspension (OV-S), and a combination of OV-S and either static standing weight-bearing activity (OV-SS) or high-incline treadmill exercise (OV-SE). OV of the plantaris resulted in significant hypertrophy and significant fast-to-slow isomyosin shifts. These changes were completely inhibited by the addition of hindlimb suspension (OV-S). Also, neither of the two weight-bearing regimes (OV-SS and OV-SE) was able to attenuate the suspension-induced atrophy. In the vastus intermedius and vastus lateralis, however, OV-SS was able to partially retard the atrophy associated with suspension. In both the plantaris and vastus intermedius, only OV-SS was able to partially reverse the slow-to-fast isomyosin transitions associated with suspension. These results suggest that the type of mechanical activity is important in determining adaptation to altered loading conditions, with OV-SS appearing more effective than OV-SE in reversing the effects of unweighting.

Abstract
The relationship between vestibular stimulation and language development in a group of five primary trainable mentally deficient and five developmentally retarded preschoolers was studied. Subjects received vestibular stimulation prior to a free play situation and were monitored for spontaneous recognizable language use. Results indicated an increase in spontaneous verbal language use for both groups immediately after the stimulation periods, and suggest vestibular stimulation as an effective nonverbal intervention method for the facilitation of spontaneous language.
