Retraction fibers (RFs) determine orientation of the cell division axis and guide the spreading of daughter cells. Long and unidirectional RFs, which are especially apparent during mitosis of cells in three-dimensional (3D) environments, enable improved control over cell fate, following division. However, 3D gel environments lack the cues necessary for...
This study investigated potential application of lactic acid bacteria (LAB) in depuration for
reducing Vibrio parahaemolyticus in oysters. Lactobacillus plantarum ATCC 8014, which
exhibited strong bactericidal effects against V. parahaemolyticus in vitro, was added to artificial
seawater for depuration of Pacific oysters (Crassostrea gigas) inoculated with V.
parahaemolyticus BE 98-2029...
Consumption of raw oysters has been linked to several outbreaks of Vibrio parahaemolyticus
infection in the United States. This study investigated effects of ice storage and UV-sterilized
seawater depuration at various temperatures on reducing V. parahaemolyticus in oysters. Raw
Pacific oysters (Crassostrea gigas) were inoculated with a mixed culture of...
Vibrio parahaemolyticus infections in the United States have been linked to consumption of raw oysters. Depuration has the potential to reduce contamination in live oysters after harvest. This study investigated the impact of depuration flow rate to reduce V. parahaemolyticus in raw oysters. Pacific oysters (n = 35 per trial)...
A beta Poisson dose-response model for Vibrio vulnificus food poisoning cases leading to septicemia was used when evaluating the effect of 15°C depuration on the estimated risk of raw oyster consumption. Statistical variability sources included V. vulnificus load at harvest, time and temperature during harvest and transportation to processing plants,...
A Monte Carlo procedure considering the variability in oyster handling from harvest to raw consumption estimated reductions in the number of Vibrio vulnificus induced septicemia cases achieved by high-pressure processing (HPP). The calculations yielded pathogen load distributions in raw oysters from harvest to consumption. In the warm season, 2-6 min...
Coring/logging data and physical property measurements from International Ocean Discovery Program Expedition 349 are integrated with, and correlated to, reflection seismic data to map seismic sequence boundaries and facies of the central basin and neighboring regions of the South China Sea. First-order sequence boundaries are interpreted, which are Oligocene/Miocene, middle...
Combined analyses of deep tow magnetic anomalies and International Ocean Discovery Program Expedition 349 cores show that initial seafloor spreading started around 33 Ma in the northeastern South China Sea (SCS), but varied slightly by 1-2 Myr along the northern continent-ocean boundary (COB). A southward ridge jump of ∼20 km...
