The three gaps A survey of publications in Conservation


The three gaps A survey of publications in Conservation

Biology between issues 1 and 12 (1986–1998) showed that of the 223 respondents, 78 % (n = 173) had included management recommendations, but of these, only 54 % (n = 164) believed their recommendations were being used (Flaspohler et al. 2000). This is the well-known knowing-doing gap, i.e. the lack of translation from theoretical knowledge into practical action. A survey of research papers dealing with conservation assessments published between 1998 and 2002 still indicated that less than one-third (n = 29, total n = 88) of conservation assessments led to any implementation (Knight et al. 2008). Two-thirds of these studies, however, did not deliver direct conservation recommendations or did not translate the findings into suitable recommendations. Because conservation advice that arose from Selonsertib solubility dmso a scientific TGF-beta inhibitor study is not implemented in practice, the knowing-doing gap is primarily a communication gap. It is related to scientists preferring to publish in peer-reviewed international journals and refraining from publishing

in the more Selleckchem PHA-848125 easily accessible and interpretable non-peer-reviewed journals as these contribute little of bibliometric value (i.e. citations, impact factors) to their scientific career—but would contribute to conversion from theory into practice (Prendergast et al. 1999). Conservation biologists are mostly employed by universities and therefore experience the general pressures of academics (teaching, tenure, publishing, grant acquisition). Conservation practitioners, on the other hand, are a much broader group that includes non-profit organizations, land managers, politicians, private landowners, etc. In contrast to the knowing-doing gap, the thematic gap highlights the discrepancy between the topics which are of interest for the respective groups, scientists or practitioners, which have been argued repeatedly to be different (e.g. Pullin et al. 2009). The thematic gap is highlighted by a recent survey asking practitioners to rate the importance of scientific findings for conservation activities.

They identified that questions related to Rapamycin order economic, societal, and stakeholder conflicts are more important than conceptual questions often addressed in research papers (Braunisch et al. 2012). This thematic gap between conservation needs and conservation research is fundamentally different from the knowing-doing gap, as research on a question not relevant for conservation cannot generate knowledge that is applicable to conservation. Hence it cannot contribute to overcoming the “not-knowing but doing” problem in conservation. For example, Linklater (2003) reported an increasing number of scientific publications about the highly endangered and declining rhinoceros species. But these studies predominantly comprised ex situ laboratory-based conservation approaches, while conservation action plans created by practitioners focused to safeguard the species in situ.

Our assay using two monoclonal antibodies appears to be specific

Our assay using two monoclonal antibodies appears to be specific because it accurately detects MLH1 and MSH2 in control cell lines that contain one or the other or both of these proteins (Figure 1A) and the assay also detects MLH1 and MSH2 proteins in mixing experiments where these proteins are present in varying proportions

(Figure 1C). Our buy Pevonedistat immunoassay also appears to be sensitive since it will detect MLH1 and MSH2 proteins in a sample from SW480 cells that contains as little as 10 ug of cellular protein (Figure 1B). Moreover, our assay appears to have an acceptable level of precision in that it is highly reproducible (Table 2). The fact that MLH1 and MSH2 are not readily detected in untreated fresh lymphocytes or monocytes is likely due to the fact that they are not rapidly proliferating. see more This is supported by the fact that MLH1 and MSH2 are detectable in immortalized lymphocytes [7], which are proliferative cells by virtue of the fact that they have been transfected with an attenuated

Epstein Barr Virus (EBV) and PHA treatment has little affect on MLH1 and MSH2 levels in these already proliferative cells. It should be noted that colon cancer cell lines (e.g., SW480) are also proliferating cells and have readily detectable levels of MMR proteins. The importance of our finding that PHA stimulation makes MLH1 and MSH2 detectable in fresh lymphocytes has relevance to the development of a practical immunoassay for the identification of carriers of an LS trait in a population-based Sodium butyrate setting. A second finding is that the distribution of MMR ratios among individuals in a genetic counseling program, which includes carriers of an LS trait, was bimodal (Figure 3) with

one peak close to 1.0 (less likely to be affected) and another lower than 1.0 (more likely to be affected). A bimodal distribution was not seen for healthy controls. This suggests that a subpopulation within the cohort of individuals at high risk for LS has substantially reduced levels of one of the two MMR proteins, which is what we predicted. This finding is consistent with our previous retrospective study [7] that also found a bimodal distribution. That earlier study was done using immortalized lymphocytes and involved individuals with a known MMR genotype, those who carried the LS trait and those who did not. Our findings are consistent with other studies [10, 11] that report microsatellite instability (MSI) in lymphocytes from LS patients – including ones with germline MSH2 or MLH1 mutations. If lymphocytes from LS patients have MSI, it can be assumed that they have reduced levels of the wild type DNA mismatch repair protein caused by the corresponding germline mutation. Another study by Marra et al [12] reported that MSH2 protein levels are decreased in immortalized lymphocytes from LS patients carrying known MSH2 germline mutations.

The β-galactosidase was released into the culture medium after os

The β-galactosidase was released into the culture medium after osmotic shock of the recombinant S. cerevisiae osmotic-remedial thermosensitive-autolytic mutants [20, 21]. To improve the secretion of the Selleck ARRY-438162 K. lactis β-D-galactosidase, cytosolic in origin, the hybrid protein from this enzyme and its A. niger homologue, that is naturally extracellular, was constructed. The hybrid protein was active and secreted by recombinant K. lactis strain, but the amount of extracellular enzyme still remained low [22]. Yeast species especially

designated for the production of extracellular proteins are for example Pichia pastoris or Hansenula polymorpha. There is only one recently published example of an extracellular

β-galactosidase production system using P. pastoris as a host, however, it concerns thermostable enzyme from Alicyclobacillus SB202190 datasheet acidocaldarius [23]. S. cerevisiae is usually the first choice for industrial processes involving alcoholic fermentation but this yeast is unable to metabolize lactose and, therefore, the lactose consuming yeast, K. fragilis, has been used in most industrial plants producing ethanol from whey [24]. The engineering of S. cerevisiae for lactose utilization has been addressed over the past 20 years by different strategies [25]. However, most recombinant strains obtained displayed no ideal characteristics (such as slow growth, genetic instability or problems derived from the use of glucose/galactose mixtures) or were ineffective for ethanol production [24, 26, 27]. There is only one published example of efficient ethanol production with a recombinant S. cerevisiae strain expressing the LAC4 (β-galactosidase) and LAC12 (lactose permease) genes of K. lactis [28]. Hence, there is still a need for S. cerevisiae

strains producing new β-galactosidases which may appear to be an interesting L-gulonolactone oxidase alternative for the production of ethanol from lactose-based feedstock. In this respect, here we report on a new cold-adapted β-D-galactosidase, isolated from psychrothrophic, Antarctic Arthrobacter sp. 32c bacterium strain, that possesses low molecular weight of 75.9 kDa of monomer and 195 kDa of native protein. In addition, the presented enzyme is active in the range of temperature 4–8°C that is suitable for milk industry applications and can be produced extracellularly on a large scale using recombinant P. pastoris strains cultivated either on methanol or glycerol (a cheap by-product in biodiesel industry). Results Characterisation of 32c isolate Many different colonies were isolated from the Antarctic soil. One isolate, named 32c, that formed yellow colonies was chosen for further study because of its ability to hydrolyze X-Gal – the cromogenic analogue of lactose. The cells were Gram-negative rods. The optimum ICG-001 in vitro growth in LAS medium was observed between 25–27°C. No growth occurred at 37°C.
