BACKGROUND Poor diet is thought to be a risk factor for many diseases, including age-related macular disease (ARMD), which is the leading cause of blind registration in those aged over 60 years in the developed world. The aims of this study were 1) to evaluate the dietary food intake of three subject groups: participants under the age of 50 years without ARMD (U50), participants over the age of...
Although sewage sludge is a rich source of nutrients for arable farming and soil improvement, it can also be a source of pollutants. The effects of the land application of sludge on the PCB and nutrient content of leachate were investigated using cylindrical 650 mm length columns filled with poor quality soil. Treatments included no fertilization (control), fertilization using a 62.5 t/ha dose ...
Filtration performance of woven geotextiles is strongly related to their pore structure parameters, i.e., percent open area (POA) and pore-opening size distribution (PSD). Current methods of determination of pore structure parameters contain inherent disadvantages, whereas image analysis, taking advantage of the two-dimensional structure of woven geotextiles, can be used effectively for this pu...
Escherichia coli O157, Salmonella enterica O30, and Citrobacter freundii F90 have identical O-antigen structures, as do E. coli O55 and S. enterica O50. The O-antigen gene cluster sequences for E. coli O157 and E. coli O55 have been published, and the genes necessary for O-antigen biosynthesis have been identified, although transferase genes for glycosidic linkages are only generic and have not...
Introduction Complete heart block rarely occurs in patients o50 years of age and is less common during pregnancy. It is important to establish that symptoms are related to the heart block, and the management of the condition may be challenging. We present a case of symptomatic complete heart block developing during pregnancy and a treatment strategy minimizing fetal exposure to ionizing radiation.
The filtration performance of a geotextile is controlled by its pore opening size distribution ~PSD!. Current methods for determining PSD are mostly indirect and contain inherent disadvantages. Recent technological advancements in image analysis offer great potential for a more accurate and direct way of determining the PSD of nonwoven geotextiles. A new and accurate method of image analysis fo...
Clostridium thermocellum polynucleotide kinase (CthPnk), the 50 end-healing module of a bacterial RNA repair system, catalyzes reversible phosphoryl transfer from an NTP donor to a 50-OH polynucleotide acceptor. Here we report the crystal structures of CthPnk-D38N in a Michaelis complex with GTP Mg and a 50-OH oligonucleotide and a product complex with GDP Mgand a 5-PO4 oligonucleotide. The O50...
BACKGROUND Studies have reported antioxidant effect of oleuropein in isolated rat heart. OBJECTIVE This study was conducted to investigate whether perfusion of isolated rat heart with oleuropein, before induction of ischemia or at the onset of reperfusion, had any effect on the hemodynamic parameters, infarct size and biochemical factors following ischemic - reperfusion injury. MATERIALS AN...
Background Information on the metabolome in early life is still limited. Here, we describe evolution of preterm babies during their first weeks life. Methods Multiple stool samples from 69 were collected across 7 hospitals UK. Volatile organic compounds (VOCs) analysed by running an aliquot (mean=80.6 mg, SD=12.3 mg) gas chromatography/mass spectrometry. Data interpreted using...
