The nematode Caenorhabditis elegans is a central laboratory model system in almost all biological disciplines, yet its natural life history and population biology are largely unexplored. Such information is essential for in-depth understanding of the nematode's biology because its natural ecology provides the context, in which its traits and the underlying molecular mechanisms evolved. We chara...

National reference standards (NRSs) for biologics are established through potency estimation by a multicenter joint study of standard materials used in the approval process for national lot release and quality control of vaccines, blood products, and other biologics. In this study, a stability evaluation was conducted to determine whether the potency of NRSs for six blood products was being mai...

Most of economic and financial time series have a nonstationary behavior. There are different types of nonstationary processes, such as those with stochastic trend and those with deterministic trend. In practice, it can be quite difficult to distinguish between the two processes. In this paper, we compare random walk and determinist trend processes using sample autocorrelation, sample partial a...

abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

conclusions the mtbdrplus and mtbdrsl genotypic testing can serve as useful additional tools for dst in a high-burden country like pakistan provided it is used in combination with phenotypic testing. results the sensitivity of mtbdrplus for isoniazid and rifampicin was found to be 88.8% and 90.2%, respectively, while sensitivity of mtbdrsl for fluoroquinolones, amikacin/capreomycin, and ethambu...

PURPOSE To evaluate the effects of tafluprost treatment for 3 years on intraocular pressure (IOP) and visual field performance. METHODS The IOP of 55 patients with normal-tension glaucoma was monitored every 1-3 months for 3 years. The Humphrey visual field test was performed every 6 months after treatment and results compared with before-treatment results. Visual field performance was also e...

Predictions of uprising or falling trends are helpful in different scenarios in which users have to deal with huge amount of information in a timely manner,such as during financial analysis. This temporal aspect in various cases of data analysis requires novel data mining techniques. Assuming that a given set of data, e.g. web news, contains information about a potential trend, e.g. financial c...

OBJECTIVE To investigate risk factors for lentigo maligna melanoma (LMM) compared with superficial spreading melanoma (SSM). DESIGN Population-based case-control study in Queensland, Australia. SETTING General community. PARTICIPANTS Population-based sample of 49 patients with LMM and 141 with SSM (in situ or invasive) aged 14 to 86 years at diagnosis in 1979 and 1980 and 232 control subj...

The objective of this study was to investigate field trends in agronomic characters of soybean (Glycine max [L.] Merr.) performance trials. Field experiments were arranged as lattice designs, and for each plot within an experiment, an environmental covariate representing the spatial trend was calculated using neighbour analysis. Correlations between environmental covariates of different charact...
