Supernatants from cell cultures (also called conditioned media, CMs) are commonly analyzed to study the pool of secreted proteins (secretome). To reduce the exogenous protein background, serum-free media are often used to obtain CMs. Serum deprivation, however, can severely affect cell viability and phenotype, including protein secretion. We present a strategy to analyze the proteins secreted by cells in fetal bovine serum-containing CMs, which combines the advantage of metabolic labeling and protein concentration linearization techniques. Incubation of CMs with a hexapeptide ligand library was used to reduce the dynamic range of the samples and led to the identification of 3 times more proteins than in untreated CM samples. Labeling with a deuterated amino acid was used to distinguish between cellular proteins and homologous bovine proteins contained in the medium. Application of the strategy to two breast cancer cell lines led to the identification of proteins secreted in different amounts and which could correlate with their varying degree of aggressiveness. Selected reaction monitoring (SRM)-based quantitation of three proteins of interest in the crude samples yielded data in good agreement with the results from concentration-equalized samples.

The traditionally coercive and state-controlled governance of protected areas for nature conservation in developing countries has in many cases undergone change in the context of widespread decentralization and liberalization. This article examines an emerging "mixed" (coercive, community- and market-oriented) conservation approach in managed-resource protected areas and its effects on state power through a case study on forest protection in the central Indian state of Madhya Pradesh. The findings suggest that imperfect decentralization and partial liberalization resulted in changed forms, rather than uniform loss, of state power. A forest co-management program paradoxically strengthened local capacity and influence of the Forest Department, which generally maintained its territorial and knowledge-based control over forests and timber management. Furthermore, deregulation and reregulation enabled the state to withdraw from uneconomic activities but also implied reduced place-based control of non-timber forest products. Generally, the new policies and programs contributed to the separation of livelihoods and forests in Madhya Pradesh. The article concludes that regulatory, community- and market-based initiatives would need to be better coordinated to lead to more effective nature conservation and positive livelihood outcomes.

There is increasing evidence to suggest that the presence of mesoscopic heterogeneities constitutes the predominant attenuation mechanism at seismic frequencies. As a consequence, centimeter-scale perturbations of the subsurface physical properties should be taken into account for seismic modeling whenever detailed and accurate responses of the target structures are desired. This is, however, computationally prohibitive since extremely small grid spacings would be necessary. A convenient way to circumvent this problem is to use an upscaling procedure to replace the heterogeneous porous media by equivalent visco-elastic solids. In this work, we solve Biot's equations of motion to perform numerical simulations of seismic wave propagation through porous media containing mesoscopic heterogeneities. We then use an upscaling procedure to replace the heterogeneous poro-elastic regions by homogeneous equivalent visco-elastic solids and repeat the simulations using visco-elastic equations of motion. We find that, despite the equivalent attenuation behavior of the heterogeneous poro-elastic medium and the equivalent visco-elastic solid, the seismograms may differ due to diverging boundary conditions at fluid-solid interfaces, where there exist additional options for the poro-elastic case. In particular, we observe that the seismograms agree for closed-pore boundary conditions, but differ significantly for open-pore boundary conditions. This is an interesting result, which has potentially important implications for wave-equation-based algorithms in exploration geophysics involving fluid-solid interfaces, such as, for example, wave field decomposition.

Opinnäytetyömme tarkoituksena oli antaa Omnia ammattikoulun media-assistenttiopiskelijoille tietoa näyttöpäätetyöhön liittyvistä kuormitustekijöistä ja ergonomiasta. Opinnäytetyömme tavoitteena on vastata kysymykseen " Mitä media-assistenttiopiskelijoiden tulisi tietää, jotta he osaisivat kuormittaa itseään sopivasti näyttöpäätetyössä?". Koostimme opinnäytetyömme kirjallisuudesta ja tutkimuksista saatujen tietojen pohjalta. Näistä muodostui opinnäytetyömme teoreettinen viitekehys sekä perustelut opinnäytetyömme tuotoksen sisällölle. Tutkimusten mukaan tuki- ja liikuntaelimistön kuormituksen tasaamiseen voi vaikuttaa vähentämällä haitallisesti kuormittavia työjaksoja, vaihtamalla työasentoja, säätämällä työvälineitä ja tauottamalla työntekoa. Opinnäytetyömme kirjallisessa osiossa perehdyimme näyttöpäätetyön ergonomiaan ja kuormittavuuteen media-assistenttiopiskelijoilla. Opinnäytetyömme tuotoksena oli "Kevennä kuormitusta näyttöpäätteen äärellä"- CD-Rom, jossa on 39 diaa. CD-Rom sisältää tietoa niska-hartiaseudun ja selän rakenteesta sekä toiminnasta, lihastyötavoista, niskaa ja selkää kuormittavista tekijöistä näyttöpäätteen äärellä työskennellessä, työpisteen säätelystä ja optimaalisesta istuma-asennosta, sekä vinkkejä kuormituksen keventämiseen mm. tauottamisen avulla. Testasimme CD-Rom:n sisältöä yhdellä Omnia ammattikoulun media-assistenttiopiskelijaryhmällä järjestämällä ergonomiaohjauksen. Palautteen pohjalta kehittelimme työn lopulliseen muotoonsa. Opinnäytetyömme tuotosta käytetään Omnia ammattikoulun media-assistenttiopiskelijoiden ergonomiaohjauksen välineenä. Työmme soveltuu myös muiden näyttöpäätteen äärellä työskentelevien henkilöiden ja ryhmien ergonomiaohjauksen välineeksi. "Kevennä kuormitusta näyttöpäätteen äärellä" - CD-Romia voivat hyödyntää fysioterapeutit, muut ergonomiaohjauksia antavat toimihenkilöt sekä Kunto-Stadia.

Analysis of variance is commonly used in morphometry in order to ascertain differences in parameters between several populations. Failure to detect significant differences between populations (type II error) may be due to suboptimal sampling and lead to erroneous conclusions; the concept of statistical power allows one to avoid such failures by means of an adequate sampling. Several examples are given in the morphometry of the nervous system, showing the use of the power of a hierarchical analysis of variance test for the choice of appropriate sample and subsample sizes. In the first case chosen, neuronal densities in the human visual cortex, we find the number of observations to be of little effect. For dendritic spine densities in the visual cortex of mice and humans, the effect is somewhat larger. A substantial effect is shown in our last example, dendritic segmental lengths in monkey lateral geniculate nucleus. It is in the nature of the hierarchical model that sample size is always more important than subsample size. The relative weight to be attributed to subsample size thus depends on the relative magnitude of the between observations variance compared to the between individuals variance.
