Early-life experiences can shape life histories and population dynamics of wild animals. To examine whether stressful stimuli experienced in early resulted carryover effects later stages, we conducted several experimental manipulations then monitored fish with passive integrated transponder tags during juvenile out-migration adult return migration. In total, 3,217 brown trout (Salmo trutta) wer...

(1) Background: The Clearfield™ system (CL) is currently the primary tool for selective weedy-rice management in irrigated rice. However, herbicide persistence soil may cause damage to successive crops. Thus, it necessary understand agricultural practices that can favor dissipation of these herbicides. objective this study was analyze factors affect imidazolinones and use information provide st...

A bioassay study was conducted to determine the differences in susceptibility of selected crops simulated imazethapyr residues based on morphological and anatomical parameters. Sugar beet, white mustard, rapeseed oil were found be most sensitive ED50 values for root length fresh weight. Corn sunflower less sensitive, wheat least sensitive. The measured parameters confirmed different sensitiviti...

essary, which greatly increases throughput and reduces the risk of carryover contamination. Our data highlight the concept that the detection of tumor-associated RNA in plasma may be a promising new direction for cancer detection. Recent advances in the expression genetics of cancer have successfully identified large panels of differentially expressed genes in human malignancies (10 ) and could...

We describe an adaptation of automated multiple flow-injection analysis instrumentation to an analysis for albumin in serum. The bromcresol green reaction was used to test the utility of the system. The approach yielded albumin results with excellent sensitivity, no measurable carryover, a relative standard deviation of less than 1%, good correlations with published procedures, and no measurabl...

Molecular beacons are oligonucleotide probes that become fluorescent upon hybridization. We designed molecular beacons to detect a point mutation in the methylenetetrahydrofolate reductase (MTHFR) gene, a mutation that has been related to an increased risk for cardiovascular disease and neural tube defects. The application of molecular beacons enables fast, semiautomated, accurate mutation dete...

A common finding in task-switching studies is switch preparation (commonly known as the preparation effect), in which a longer interval between task cue and trial stimulus (i.e., a longer stimulus onset asynchrony, or SOA) reduces the cost of switching to a different task. Three experiments link switch preparation to within-subjects manipulations of SOA. In Experiment 1, SOA was randomized with...
