The 2.05-Å resolution structure of the aquaglyceroporin from the malarial parasite Plasmodium falciparum (PfAQP), a protein important in the parasite’s life cycle, has been solved. The structure provides key evidence for the basis of water versus glycerol selectivity in aquaporin family members. Unlike its closest homolog of known structure, GlpF, the channel conducts both glycerol and water at...

Escherichia (E.) coli and Salmonella (S.) choleraesuis (subsp. choleraesuis and subsp. salamae) from apparently healthy slaughtered cattle and pigs in 1989 in Zambia, were examined for antibiotic resistance and the presence of conjugative R plasmid. Salmonella strains from diseased animals (cattle, chickens, leopards, lions and warthogs) were similarly tested. The majority of the cattle had bee...

Powder bed binder jet printing (BJP) is an additive manufacturing method in which powder is deposited layer-by-layer and selectively joined in each layer with binder. The data presented here relates to the characterization of the as-received feedstock powder, BJP processing parameters, sample preparation and sintering profile ("Effect of solutionizing and aging on the microstructure and mechani...

Dysregulated microRNA (miR)-625 expression has been observed in several kinds of cancer. MicroRNAs are important factors in the development and progression of malignant melanoma, though the clinical significance and function of miR-625 in human malignant melanoma remain unclear. Levels of miR-625 expression were therefore determined in 36 pairs of malignant melanoma and adjacent non-tumor tissu...

This survey aimed to evaluate the level of lead (Pb) pollution in cattle in the vicinity of the Shiraz oil and petrochemical industries using hair samples. Dairy farms located within 10 km of the Shiraz oil and petrochemical industries were identified and divided into four groups. Farms that were located in the radial zones of 0.5-1.5 km, 1.5-5 km, 5-7 km, 7-10.5 km were considered as groups A,...

seventy poultry farms’ drinking water was tested for escherichia coli contamination in qom province iniran. the cases of colibacillosis from positive farms were also collected and tested. the isolates wereexamined for serotype, detection of virulence genes by multiplex pcr and antibiotic resistance. thirtypoultry farm water samples were e. coli positive (18.57%), although 13 e. coli isolates we...

A randomised controlled trial was used to investigate the effect of three complex management intervention packages to reduce the burden of E. coli O157 in groups of young-stock on cattle farms in England and Wales. All intervention farms were assigned measures to avoid buying in new animals and having direct contact or sharing water sources with other cattle. Furthermore, package A (7 farms) ai...

Microbiological analyses of fruits and vegetables produced by farms in Minnesota and Wisconsin were conducted to determine the prevalence of Escherichia coli in pre-harvest fruits and vegetables. During the 2003 and 2004 harvest seasons, 14 organic (certified by accredited organic agencies), 30 semi-organic (used organic practices but not certified) and 19 conventional farms were sampled to ana...

In the Alps, summer farms are temporary units where the livestock herds are moved during summer to graze on highland pastures. Th is study aimed to analyze the role of summer farms in the dairy farming systems of the Trento province, in the eastern Italian Alps. Data on the structures and management of the 395 active summer farms were collected from the veterinarian services of the province: 34...
