Origin and Offshore Extent of Floating Algae in Olympic Sailing Area

Abstract: Extensive patches of floating algae have appeared since mid-June in coastal waters off Qingdao, China, where the Olympic sailing competitions will be held on 9–23 August. By 27 June, field surveys showed that the patches occupied about 30%, or 15 square kilometers, of the 50-square-kilometer region designated for the competitions, posing potential problems for them, according to reports in local news media. The floating algae, whose spatial extent is the largest ever reported in the literature for the world's oceans (as revealed by satellite estimates indicated below), have attracted wide national and international attention since late June.

Midlife vascular risk factors and the risk of Alzheimer's disease: a systematic review and meta-analysis.

Abstract: Background/objective We examine whether midlife vascular risk factors (VRFs) are associated with increased risk of incident Alzheimer's disease (AD) in a systematic review and meta-analysis of published cohort studies. Methods Original cohort studies were included if they reported adjusted combined odds ratio (COR) and corresponding 95% confidence intervals (CIs) or enough information to quantify the association between risk for AD in late-life and baseline VRFs of midlife. Results There were positive and significant associations between high blood pressure (COR 1.31; 95% CI: 1.01-1.70), hypercholesterolemia (COR 1.72; 95% CI: 1.32-2.24), obesity (COR 1.88; 95% CI: 1.32-2.69), and diabetes mellitus in midlife (COR 1.4; 95% CI: 1.25-1.57). Smoking and hyperhomocysteinemia (although only one high-quality paper) were also associated with an increased risk of AD generally. Conclusions These results strengthen the epidemiological evidence that VRFs of midlife significantly increase risk for AD.

Optimal dietary protein requirement of grouper Epinephelus coioides juveniles fed isoenergetic diets in floating net cages

Abstract: Summary An experiment to determine the optimal protein requirement of grouper Epinephelus coioides juveniles was conducted in floating net cages (1.5 m × 1 m × 1.5 m). Six isoenergetic fishmeal–casein-based experimental diets containing 350–600 g kg−1 crude protein (CP) were fed to triplicate groups of 20 fish (10.7 ± 0.2 g) for 56 days. Weight gain (WG) and specific growth rate (SGR) increased with increasing dietary protein level from 350 to 450 g kg−1 and then plateaued above these levels. Feed intake (FI) showed no significant difference among fish fed more than 350 g kg−1 CP. Lowest feed conversion ratio (FCR) was found for fish fed 500 g kg−1 CP but this was not significantly different from that of fish fed the 450 and 600 g kg−1 CP. Lowest protein efficiency ratio (PER) was found for fish fed 550 and 600 g kg−1 CP. Fish fed the 600 g kg−1 CP had the highest body protein and moisture contents but the lowest body lipid content. Body ash content was unaffected by protein level for fish fed >400 g kg−1 CP. Dietary protein level had no significant effect on hepatosomatic index (HSI). Fish fed the 350 g kg−1 CP had significantly lower condition factor (CF) and viscerosomatic index (VSI). Based on broken-line regression analysis of SGR the optimal dietary protein requirement for E. coioides juveniles was determined to be close to 480 g kg−1.
