Crustaceans are known for their trace element bioaccumulation abilities. Muscle tissues of lagoon crab, marine pink shrimp and mantis marketed consumption in Nigeria were analyzed Mn, Fe, Cu, Zn, Hg Cr levels using standard methods. mg kg-1 Mn (0.03±0.00 crab), Fe (0.072±0.01 shrimp), Cu (0.344±0.01 crab) Zn (0.073±0.00 shrimp) significantly different (p<0.05) from corresponding values other...

Mitochondria isolated from the hepatopancreas of the blue crab Callinectes sapidus show up to 12-fold stimulation of respiration on addition of Ca(2+), which is accompanied by Ca(2+) accumulation (Ca(2+):site = 1.9) and H(+) ejection (H(+):Ca(2+) = 0.85). Sr(2+) and Mn(2+) are also accumulated; Mg(2+) is not. A strongly hypertonic medium (383 mosM), Mg(2+), and phosphate are required for maxima...

Crustacean allergy is a major cause of food-induced anaphylaxis. We showed previously that heating increases IgE reactivity of crustacean allergens. Here we investigate the effects of thermal processing of crustacean extracts on cellular immune reactivity. Raw and cooked black tiger prawn, banana prawn, mud crab and blue swimmer crab extracts were prepared and IgE reactivity assessed by ELISA. ...

The purpose of this study was to find an alternative instrumental method to sensory analysis and to further investigate the aroma properties of spoiling blue crab meat. This was accomplished by use of a Cyranose 320TM Electronic Nose, Draeger-Tubes®, and solid-phase microextraction gas chromatography-mass spectrometry (SPME-GC-MS). These techniques were compared to the more established techniqu...

The high luminosity upgrade planned for the LHC requires crab cavities to rotate bunches into alignment at the interaction points. They compensate for a crossing angle near to 500 μRad. It is anticipated that four crab cavities in succession will be utilized to achieve this rotation either side of each IP in a local crossing scheme. A crab cavity operates in a dipole mode but always has an acce...

Each spring adult horseshoe crabs migrate from deep bay waters and the Atlantic continental shelf to intertidal sandy beaches to spawn. Horseshoe crabs are an important food source for migrating shorebirds that feed on the eggs, for migrating fish that feed on the eggs and larvae and for Atlantic loggerhead turtles that feed on horseshoe crabs while using the Chesapeake Bay as a summer nursery ...

OBJECTIVES This investigation was conducted to study co-colonization by carbapenem-resistant Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) and Acinetobacter baumannii (CRAB) in intensive care unit (ICU) patients in Palermo, Sicily, a geographic area where both organisms are endemic in the healthcare setting. Risk factors at admission and during ICU stay and outcomes were ...

This in vitro study aimed to determine the activity of colistin plus sulbactam and colistin plus fosfomycin against carbapenem-resistant A. baumannii (CRAB). Fifteen clinical isolates were obtained from patients admitted to Phyathai II International Hospital, Bangkok, Thailand, from August 2014 to April 2015. The antimicrobial susceptibilities of colistin, sulbactam, and fosfomycin were evaluat...

Coupling experiments at small spatial scales with large-scale surveys can help to generalize experimental results across large spatial scales. The goal of the present study was to evaluate patterns of crab herbivory within and, at a larger scale, between many southwestern (SW) Atlantic salt marshes. Hence, we conducted experiments in an Argentinean salt marsh to elucidate the effects of crab Ch...

Interannual variability in the abundances of blue crab (Callinectes sapidus) in populations along the U.S. east coast is well documented, but the mechanisms driving these fluctuations remain poorly understood. Using principal component analysis and dynamic factor analysis we quantified the patterns in variability and the degree of synchrony among blue crab populations along the U.S. east coast ...
