The occurrence and behavior of wastewater indicator compounds in the Santa Arm River (SAR) water and the underlying aquifer recharged by the SAR has been studied. The SAR contains a high proportion of tertiary treated wastewater effluents, up to 100% during summer and fall. The following water quality parameters were quantified: four specific wastewater indicator compounds, ethylene diaminetetr...

The objectives of this research work was to evaluate the reduction of THM precursors by cationic pDADMAC and determine the correlations between the chlorine demand and trihalomethane formation in the presence of electrolyte solutions and ambient light. The chlorine demand was found to be significantly reduced provided that the H2SO 4 electrolyte was fed to the sample solutions. The amount of CH...

The present study was conducted to determine the effects of L-carnosine (LC) and/or alpha-lipoic acid (ALA) supplementation on growth performance, blood thyroid hormones and lipid profiles in finishing pigs. A total of 40 (Landrace×Yorkshire) pigs with an initial body weight of 57.93±3.14 kg were randomly allocated to 4 experimental diets using a 2×2 factorial arrangement with 2 LC supplemental...

BACKGROUND Plasma Citrulline concentration has been correlated to functional enterocyte mass. Dried blood spot (DBS) analysis using LC-MSMS reduces sample amount needed. We optimized DBS elution to increase precision and accuracy of DBS LC-MSMS analysis. METHOD DBS control samples were eluted in varying pH (2.2-7.0) and for varying times (15-75 min) and Cit, Arg and Orn were analyzed using LC...

Laundry detergent containing anionic surfactants was used to test their effects on plant growth through irrigation water. Lettuce and okra were cultivated in pot experiment and irrigated with distilled water containing domestic detergent at three different concentrations: low concentration (LC) of 0.1 g L-1; normal concentration (NC) of 1.0 g L-1 and high concentration (HC) of 5.0 g L-1 and dis...

Bromodeoxyuridine (BrdU) labeling indices (LI) of liver biopsied specimens from 27 control liver cirrhosis patients (control LC) without hepatocellular carcinoma (HCC), 26 cirrhotic patients with HCC, and from 6 control subjects were examined using an in vitro BrdU labeling technique. The mean BrdU LI +/- S.E. of HCC cancerous portion, HCC non-cancerous cirrhotic portion, control LC, and contro...

Online comprehensive two-dimensional liquid chromatography (LC × LC) offers ways to achieve high-performance separations in terms of peak capacity (exceeding 1000) and additional selectivity to realize applications that cannot be addressed with one-dimensional chromatography (1D-LC). However, the greater resolving power of LC × LC comes at the price of higher dilutions (thus, reduced sensitivit...

Bottom-up proteomics provides often small amounts of highly complex samples that cannot be analysed by direct mass spectrometry (MS). To gain a better insight in the sample composition, liquid chromatography (LC) and (comprehensive) two-dimensional (2D-LC or LC × LC) can coupled to MS. Low-flow separations are attractive for HRMS analysis, but they tend lengthy. In this work, low-flow, online, ...

AIM OF THE STUDY To determine the cost-effectiveness of lung cancer (LC) screening with low-dose computerised tomography of the chest, as compared to an approach without screening, reimbursed today by the National Health Fund (NHF) in Poland. MATERIAL AND METHODS In order to analyse the current costs of diagnostic and therapeutic procedures of a model LC patient treated today, a model group c...

It was hypothesized that metabolic programming of processes underlying puberty can be shifted temporally through the use of a stair-step compensatory growth model such that puberty is optimally timed to occur at 11 to 12 mo of age. Forty crossbred beef heifers were weaned at approximately 3.5 mo of age and, after a 2-wk acclimation period, were assigned randomly to 1 of 4 nutritional groups: 1)...
