TL;DR: Ginsenoside Rg1 induced an augmentation of the production of IL-1 by macrophages and exerted a direct mitogenic effect on microcultured thymus cells, and partly restored the impaired immune reactivity by cyclophosphamide treatment.

TL;DR: A genetic algorithm-called BASIC, which is designed to take advantage of well known genetic schemes so as to be able to deal with numerous optimization problems, and provides an opportunity to the genetic operators to be extended with new schemes.

TL;DR: In this paper, the first results of the differential cross-section are presented covering a |t|-range from 0.36 to 2.5 GeV 2, where |t is the square of four-momentum transferred in the elastic scattering process.
Abstract: Proton-proton elastic scattering has been measured by the TOTEM experiment at the CERN Large Hadron Collider at √ s = 7 TeV in dedicated runs with the Roman Pot detectors placed as close as seven times the transverse beam size (σbeam) from the outgoing beams. After careful study of the accelerator optics and the detector alignment, |t|, the square of four-momentum transferred in the elastic scattering process, has been determined with an uncertainty of δt = 0.1 GeV p |t|. In this letter, first results of the differential cross-section are presented covering a |t|-range from 0.36 to 2.5 GeV 2 . The differential cross-section in the range 0.36 < |t| < 0.47 GeV 2 is described by an exponential with a slope parameter B =( 23.6 ± 0.5 stat ± 0.4 syst )G eV −2 , followed by a significant diffractive minimum at |t| =( 0.53 ± 0.01 stat ± 0.01 syst )G eV 2 .F or|t|-values larger than ∼ 1. 5G eV 2 , the cross-section exhibits a power law behaviour with an exponent of −7.8 ± 0.3 stat ± 0.1 syst . When compared to predictions based on the different available models, the data show a strong discriminative power despite the small t-range covered. open access Copyright c EPLA, 2011

TL;DR: An overview of the available methods for studying propolis in different aspects is given in this article, where the authors give an overview of different aspects of propolis, such as propolis production in the bee colony, chemical composition and plant sources, biological activity, and standardization and quality control for industrial application.
Abstract: Propolis is one of the most fascinating honey bee (Apis mellifera L) products It is a plant derived product that bees produce from resins that they collect from different plant organs and with which they mix beeswax Propolis is a building material and a protective agent in the bee hive It also plays an important role in honey bee social immunity, and is widely used by humans as an ingredient of nutraceuticals, over-the-counter preparations and cosmetics Its chemical composition varies by geographic location, climatic zone and local flora The understanding of the chemical diversity of propolis is very important in propolis research In this manuscript, we give an overview of the available methods for studying propolis in different aspects: propolis in the bee colony; chemical composition and plant sources of propolis; biological activity of propolis with respect to bees and humans; and approaches for standardization and quality control for the purposes of industrial application

TL;DR: In this paper, the solution behavior of poly(2-ethyl-2-oxazoline) (PEtOx) in water has been investigated, and the dependence of the cloud points on the molecular weight and concentration indicates a typical Flory-Huggins demixing behavior with a lower critical solution temperature (LCST).
