Currently used industry testing programs require the ability to detect Escherichia coli O157:H7 in samples of beef trim or ground beef at levels as low as 1 CFU/375 g. We present a reliable protocol for generating a control inoculum for verification testing at this low concentration and evaluate its use. Results show that half of all samples received no cells when 1 CFU was the target concentra...

Horzinek, Marian (Tierärztliche Hochschule, Hannover, West Germany). Characterization of hog cholera virus. I. Determination of buoyant density. J. Bacteriol. 92:1723-1726. 1966.-Hog cholera virus was subjected to cesium chloride density gradient centrifugation. Most of the infectious activity was detected in fractions with densities between 1.15 and 1.20 g/ml, with a peak at 1.16 g/ml. Infecti...

The DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT) removes mutagenic adducts from the O6 position of guanine, thereby protecting the genome against G to A transition mutations. MGMT is inactivated by promoter hypermethylation in many human cancers and has been associated with G to A mutations in K-ras in colorectal cancer. We hypothesized that MGMT promoter hypermethylation wo...

A nanohybrid containing 2 mol% La3+ doped MnO2 and carbon nanotubes produced hydrothermally exhibits a specific capacitance of ?1530 F g?1 at 1 92% capacity retention after 5000 cycles showing its potential as electrode for supercapacitors.

AIM To determine neurosensory outcome at 8 years of age of extremely low birthweight (ELBW) children born in the 1990s, how it varies with birth weight, and how it compares with ELBW children born in the 1980s and 1970s. METHODS Subjects were born in the state of Victoria during 1991-92 and comprised 224 of 241 consecutive survivors with a birth weight of 500-999 g, and 223 of 262 normal birt...

BACKGROUND Giardia duodenalis is a species complex consisting of multiple genetically distinct assemblages. The species imposes a major public health crisis on developing countries. However, the molecular diversity, transmission dynamics and risk factors of the species in these countries are indeterminate. This study was conducted to determine the molecular epidemiology of G. duodenalis infecti...

The hyperfine structure of highly charged 238 92 U ions with rotationally excited nuclei Abstract The hyperfine structure (hfs) of electron levels of 238 92 U ions with the nucleus excited in the low-lying rotational 2 + state with an energy E 2 + = 44.91 keV is investigated. In hydrogenlike uranium, the hfs splitting for the 1s 1/2-ground state of the electron constitutes 1.8 eV. The hyperfine...
