Analysis of the abundance of ejecta boulders Z2 m in diameter on the rims of twelve lunar craters (150– 950 m in diameter) of known formation ages (2–300 Ma) led to estimates of the survival times of metersized boulders against collisional destruction on the Moon. The median survival time, when 50% of the original rock population 42 m was destroyed, is about 40–80 Ma, while the 99% survival tim...
Phytoplankton community structure at the Cariaco Basin Time-Series site (101300N, 641400W) within the Cariaco Basin was examined using high performance liquid chromatography (HPLC) and microscopy between January 1996 to October 2000, and July 2006 to December 2010. Microscopy results from the upper 55 m indicated that the abundance of microphytoplankton (420 mm) decreased by more than 5-fold fr...
Putative colonization factor PCFO20 was recently identified in an enterotoxigenic Escherichia coli (ETEC) strain of serogroup O20 isolated from a child with diarrhea in Argentina. The gene encoding the structural subunit of PCFO20 fimbriae, fotA, was cloned from strain ARG-2 in the expression phage vector lambda ZAP Express. One positive clone, pGV29, that carried a 3.3-kb fragment was identifi...
Evidence has been accumulating for some time regarding the reduced life-expectancy experienced by people living with a mental illness. In developed world settings this can involve a two-decade reduction in life expectancy, whilst in the developing world the gap may be as high as thirty years. Whilst genetic risk factors and suicide contribute to this ‘scandal of premature mortality’...
BACKGROUND The global incidence of foodborne infections and antibiotic resistance is recently increased and considered of public health concern. Currently, scarcely information is available on foodborne infections and ESBL associated with poultry and beef meat in Egypt. METHODS In total, 180 chicken and beef meat samples as well as internal organs were collected from different districts in no...

No past studies of diarrhea in children of the Middle East have examined in detail the phenotypes of enterotoxigenic Escherichia coli (ETEC) strains, which are important pathogens in this setting. During a prospective study conducted from November 1993 to September 1995 with 242 children under 3 years of age with diarrhea living near Alexandria, Egypt, 125 episodes of diarrhea were positive for...
This is the report of the American College of Veterinary Internal Medicine (ACVIM) Specialty of Cardiology consensus panel convened to formulate guidelines for the diagnosis and treatment of chronic valvular heart disease (CVHD, also known as endocardiosis and myxomatous valve degeneration) in dogs. It is estimated that approximately 10% of dogs presented to primary care veterinary practices ha...
