However, in its original definition, resilience does not recognise that social change mainly implies transitions to new forms of production, consumption and distribution with new combinations of technology, organisation, institutions and lifestyles (Jerneck and Olsson 2008). The inner logic and utility of the increasingly popular resilience framework (Folke et al. 2002) should, therefore, be scrutinised. Material flow analysis and various cycles Modern society is heavily dependent on manipulating a number of bio-geo-chemical cycles, such as: the carbon cycle for the provision of energy; the nitrogen and phosphorous cycles for

the provision of food; and the water cycle for the provision of water, food, energy and transport. In the natural sciences, the study of such cycles has resulted in biogeochemistry, an area of scientific inquiry that integrates the disciplines of biology, RG7204 solubility dmso geosciences and chemistry (Schlesinger 1997; ABT-263 order Megonigal 2002).

Material flow analysis (MFA) represents a similar development in the social sciences, as mentioned above. To some extent, MFA resembles macro-economic modelling, with the difference that MFA deals with physical units of materials rather than monetary units. The challenge to integrate the complete cycles, both the natural and the social components of these cycles, is at the very heart of sustainability science. But this requires a rethinking of the ontology and epistemology of disciplines. The natural science ontology

of the carbon cycle is based on carbon as a bio-physical entity. If the ontology is reframed to incorporate also carbon used in the manufacturing, transporting and consumption of goods, then the cycling of carbon becomes as much a social as a natural cycle. Analogous reasoning of integration can be applied to the water and the nutrient cycles. Theme two: sustainability goals This theme explores the process of formulating and establishing various global sustainability goals, including their very content. Since Molecular motor the publication of ‘Our Common Future’ in 1987 (WCED 1987), social goal setting has changed from a broad qualitative vision of a sustainable society to more precise policies, including specific planning instruments and targets of efficiency and effectiveness that are measurable in quantitative terms, such as the Lisbon Agenda in the EU (Gros 2005). The Brundtland Commission (WCED 1987) defined sustainable development as development that “meets the needs of the present without compromising the ability of future generations to meet their own needs.” The concept, comprising environmental, economic and social pillars, is subject to criticism on many grounds, especially for its ambiguity and the lack of tangible operationalisation.

9% NaCl as collecting fluid (exact volume determined for each sample). The samples were frozen at -80 °C and shipped to Zürich on dry ice for further analyses. There, freshly defrosted samples were vortexted for 1 min, sonicated for 5 s, aliquoted and assessed by FISH. Aliquots were also grown at 37 °C anaerobically and in 10% CO2 on LBS agar (Becton Dickinson) with the aim to isolate and type representative strains by partial 16S Trametinib cost rDNA sequencing. Demineralization of discs was determined by quantitative

light-induced fluorescence as described [29]. Preparation of multi-well slides for FISH Overnight cultures of lactobacilli (LBS broth) were washed in 0.9% NaCl, diluted in coating buffer [30], spotted on 18- or 24-well

slides (Cel-Line Associates), air-dried, and fixed in 4% paraformaldehyde/PBS (20 min, 4 °C). Analogously, in situ grown biofilm samples, supragingival plaque samples and tongue scrapings were vortexed at maximum speed for 60 s, diluted in coating buffer and coated to 18- or 24-well slides as described [30]. To improve cell wall permeability https://www.selleckchem.com/products/GDC-0980-RG7422.html each well selected for FISH of lactobacilli was treated individually at room temperature first for 5 min with 9 μl of lysozyme (1 mg ml-1; Sigma-Aldrich L-7651) and achromopeptidase (1 mg ml-1; Sigma-Aldrich A-7550) Thiamine-diphosphate kinase in Tris-HCl (pH 7.5) with 5 mM EDTA, and then for 30 min with 9 μ l of lipase (Sigma-Aldrich L-1754; at 25 mg ml-1 in water the lipase suspension was centrifuged for 5 min at 16’000 × g after which the supernatant was used). Thereafter, to limit unspecific FISH probe binding all wells were covered for 30 min at 37 °C with 9 μ l of PBS containing Denhardt’s solution (Fluka 30915; diluted 1:50) in the presence of protectRNA RNase inhibitor (Sigma-Aldrich R-7397; diluted 1:500) [15, 16, 26, 27]. At the end of the respective incubation periods the solutions were carefully aspirated and the slides briefly washed

in wash-buffer (0.9% NaCl, 0.05% Tween 20, 0.01% NaN3), dipped in water, and air-dried. All solutions were made with water of nano-pure quality. Fluorescent in situ hybridization The 16S rRNA targeted oligonucleotide probes used in this study are listed in Table 1. Custom-synthesized by Microsynth, they were labeled at 5′-end with Cy3 or 6-FAM, or in some cases at both ends with 6-FAM. Probes marked by “”L-”" in front of the probe name, contain one or two LNA to improve in situ hybridization efficiency [16]. Probes were designed as described previously [30] using the ARB software [31] with the SILVA rRNA database [32, 33] and additional rRNA sequence information from ‘The Ribosomal Data Base Project II’ [34, 35] and the ‘National Center for Biotechnology Information’ [36].

g. oak Quercus robur, lime Tilia cordata, maple Acer platanoides, ash Fraxinus excelsior, elm Ulmus glabra, and hazel Corylus avellana, on richer soils and on sites with a warmer microclimate. All land with southern deciduous trees is much affected by present and former human land-use. Lime trees rarely dominate the stands, being rather scattered among other southern deciduous trees, mainly oak. Parks and a few other stands are exceptions. As in most of Europe, the older trees in the Mälaren area grew up in a landscape with large areas of hay meadows and grazing lands for cattle (Emanuelsson 2009), which are today PCI-32765 order either still grazed or

regrowing with younger trees. Fig. 1 Map over the sampling sites. Characteristics

for the sites CHIR-99021 mouse are listed in Table 6 Lime trees were often pollarded to produce winter fodder for cattle, and wood, including the tough fibres in the bast, for a variety of uses. This practice was almost totally abandoned in the first half of the 1900s, but on many of the inventoried sites the trees have a conspicuous conformation from having been pollarded in earlier times. Lime trees in parks have also usually been pollarded, but for aesthetic reasons. On some of the natural stands however, there are no visible traces of pollarding. The limes in the natural sites are the small-leaved lime T. cordata, whereas most limes in parks are the common lime T. × europea, a hybrid between T. cordata and T. platyphyllos (Bengtsson 2005). Around lake Mälaren there are many old estates that were built by the nobility. As described above, most of these estates had large parks established 250–350 years ago, an important feature of which were avenues of limes. Selection

of sites Most study sites were selected for survey according to the criterion that they should contain lime trees that had the potential to host those species encompassed by an action plan for saproxylic beetles on lime (Ehnström 2006; Jonsell and Sahlin 2010) i.e. sites with old hollow lime-trees. The selection was mainly made by the county administrative boards in the respective county (three are included) based on information from inventories of valuable trees IMP dehydrogenase and on their personal knowledge. In addition, data from three other park inventories were included in this study (Andersson 2010; Jonsell 2004, 2008). In total, 27 sites were used and they were categorised as either ‘Open’ (8), ‘Re-grown’ (11) or ‘Park’ (8). The maximum area of a site was a few hectares, but was usually less than one. Each site was registered by GPS according to its Swedish national grid coordinates, RT90, where one unit = 1 m. All ‘Open’ sites were grazed wooded meadows (Fig. 2a). Lime dominated only one site. In the other sites lime was mixed with other coarse trees, mainly oaks.

Imports for non-commercial purposes, e.g. exchange between zoos or export for scientific purposes, over this

period involved <700 live individuals and are excluded here. Numbers of dendrobatid frogs in international zoos and aquariums (excluding hybrids) were retrieved from the International Species Information System website (https://​app.​isis.​org/​) listing collection information from its 735 institutional members (zoos, Saracatinib aquariums, and other zoological collections). Systematics of poison arrow frogs is a field in motion, with seemingly ever-changing genus and species names; for consistency we followed the taxonomy as used in the WCMC-CITES database which is based on Frost (2004) and Brown et al. (2006). Definitions in this paper follow those of CITES (2009): ‘captive-bred’ refers to at least second generation offspring of parents bred in a controlled captive environment (or first generation offspring from a facility that is managed in a manner that has been demonstrated to be capable of reliably producing second-generation offspring in a controlled environment); ‘F1 captive-bred’ refers to specimens born in captivity

to wild-caught parents and that are not considered as captive selleck bred under CITES; ‘ranch-raised’ refers to specimens either directly removed from the wild and reared in a controlled environment or progeny from gravid females captured from the wild; ‘wild-caught’ refers to specimens that originate from the wild. While we know to which country specimens are imported, and for what purposes, we do not have information who are the individuals or organisations behind the imports; therefore ‘country MycoClean Mycoplasma Removal Kit X imports….’ is shorthand for ‘traders or other

individuals or institutions operating in country X import….’ and does not necessary imply that it is the government or government institutions of country X that does the importing. Results From 2004 to 2008, a total of 32 species were reported to CITES as being commercially traded, totalling 63,165 specimens of live dendrobatid frogs of four genera, i.e. Dendrobates, Phyllobates, Epipedobates and Cryptophyllobates (Table 1). For all but one species (E. trivittatus), the majority of individuals was reported as captive-bred, with all imports for 21 species declared as originating from captive-bred sources (captive-bred and F1 captive born). Seven species are ranched in relatively small numbers (mainly in Panama and Peru) and imports of five species include wild-caught individuals (from Guyana, Panama and Suriname).

We established HT-29 human colorectal cells and MCF-7 breast cancer cells stably transfected with the pcDNA-CSE1L vector, a eukaryotic expression vector carrying the full-length human CSE1L cDNA to study the effect of increased CSE1L expression on cancer cell apoptosis induced by chemotherapeutic drugs [12, 13]. The chemotherapeutic drugs we tested including paclitaxel, doxorubicin,

5-fluorouracil, cisplatin, etoposide, and 4-OH-tamoxifen. Our results showed that CSE1L regulated cancer cell apoptosis MK2206 induced by most of the chemotherapeutic drugs that we tested [12, 13]. Increased CSE1L expression enhanced apoptosis induced by doxorubicin, 5-fluorouracil, cisplatin, and 4-OH-tamoxifen, but decreased apoptosis induced by paclitaxel in HT-29 cancer cells and MCF-7 cancer cells [12, 13]. Therefore, CSE1L-mediated apoptosis is not limited to apoptosis induced by ADP-ribosylating toxins and tumor necrosis factor. Microtubules are the target of paclitaxel-induced cancer cell apoptosis [12], thus the expression of microtubule-associated protein may have an impact on cancer cell apoptosis induced by paclitaxel. For example, selleck the expression of the microtubule-associated protein, caveolin-1, was reported to enhance paclitaxel-mediated apoptosis of MCF-7 cells [17]. Low expression level of the microtubule-binding protein, tau, was reported to enhance the sensitivity

of human breast cancer to paclitaxel treatment [18]. CSE1L is also a microtubule-associated protein [5]. Paclitaxel treatment can block or prolong cells in the G2/M phase of the cell cycle during apoptosis induction [19], and to induce microtubule aster formation in apoptotic cells [20]. Cell cycle analyses showed that increased CSE1L expression inhibited paclitaxel-induced G2/M phase cell cycle arrest, and immunofluorescence

studies showed that increased CSE1L expression inhibited paclitaxel-induced microtubule aster formation in cells [12]. Therefore, 4��8C CSE1L might inhibit paclitaxel-induced apoptosis by affecting G2/M phase cell cycle arrest and microtubule aster formation induced by paclitaxel. CPP32 (caspase-3) is one of the central apoptosis executioner molecules, and elevation of cleaved CPP32 is a sign of increased apoptosis [21]. Pathological studies showed that the expression of CPP32 was positively correlated with CSE1L expression in endometrial carcinoma (p = 0.008) [22]. Increased CSE1L expression can enhance both interferon-γ-induced CPP32 expression and the level of the cleaved CPP32 product, thereby inducing apoptosis of HT-29 cancer cells [23]. Therefore, the CPP32 apoptotic pathway is involved in CSE1L-mediated cancer cell apoptosis. p53 is crucial in mediating cell apoptosis induced by various apoptosis-inducing stimuli, and most chemotherapeutic drugs exert their antitumor activity through a p53-dependent mechanism [24–28].

The specimens of tumor xenografts, the skins around the tumors, hearts, livers and lungs, were immediately harvested, embedded in optimal cutting temperature

compound (OCT, Tissue-Tek, Sakura Finetek, Torrance, CA, USA), and stored at -80°C until further analyses. Cross sections buy LDK378 (10 μm-thick slices) were cut with a cryostat (CM1900, Leica, Germany) and affixed to glass slides. Fluorescence expression and distribution pattern were observed with confocal laser microscopy (Fluoview FV500, Olympus, Japan). Digital image subtraction method was devised to eliminate autofluorescence. Slices were coded so that analyses were performed without knowledge of which treatment each individual HIF inhibitor animal had received. For each sample, RFP expression and transfection efficiency were evaluated in six randomly chosen fields per section. For examination of luciferase reporter gene expression, tumor xenografts and the non-targeted organs in group d and e were removed and homogenized, frozen in liquid nitrogen, and stored at -80°C. Luciferase activity in the tissue lysate was measured using a Lumat LB9507 instrument (Berthold, Bad Wildbad, Germany). Luciferase background (100-200 RLU) was subtracted from each value and transfection efficacy

is expressed as RLU/organ or RLU/tumor [31]. One million RLU correspond approximately to 2 ng luciferase. Gene Silencing and Apoptosis Induction Effects of shRNA Expression Vector Targeting Survivin Transfected by UTMD and PEI A total of 18 mice were randomly divided into 3 experimental groups, 6 mice each group. Control group, mice were received injections of PBS; pSIREN-S +UTMD group, mice were received injections of pSIREN-S/SonoVue and followed by local ultrasound Megestrol Acetate irradiation; pSIREN-S

+ UTMD + PEI group, mice were received injections of pSIREN-S/SonoVue/PEI complexes and followed by local ultrasound irradiation. All injections were performed with the plasmid DNA dose of 30 μg/mouse. The number of dead mice was noted every day. 21 days after injection, the tumor-bearing mice were humanely sacrificed and the solid tumors were harvested. Immunohistochemistry The samples were fixed with formaldehyde, dehydrated with a graded alcohol series, and embedded in paraffin. The sections were incubated with primary antibodies against survivin, bcl-2, bax and caspase-3 (1:100 dilution, Santa Cruz Biotechnology) and then incubated with appropriate biotinylated secondary antibody as detailed previously [32]. The colorimetric detection was performed by using a DAB detection kit (Boster Biological Technology Co. Ltd., Wuhan, China). Images were acquired with a microscope (BX51, Olympus, Japan). The assessment of the immunohistochemical results were modified from that described previously [33, 34].

Finally, the sample was spin-coated at 500 rpm for AZD1152-HQPA mouse 6 min (spin coater: Laurell Technologies Corporation, North Wales, PA, USA; model: WS-400B-6NPP/LITE). The polyNIPAM microspheres were fixed to the surface by silanization. For this purpose, the samples were treated with APTES vapor for 30 min and afterwards baked at 80°C for 1 h. Results and discussion In Figure 1a,b, SEM images of a bare pSi film as well as a pSi film covered with polyNIPAM microspheres, taken at high magnification, are displayed. SEM images

taken at low magnification can be found in Additional file 1: Figure S1. High-magnification SEM images reveal that both porous layers have open pores. The polyNIPAM spheres appear as black circles and form a quasi-hexagonally non-close packed array on top of the pSi layer, whose geometrical arrangement was analyzed with the software package ImageJ. Of the porous surface, 42 ± 3% was covered with hydrogel spheres with a diameter of 837 ± 17 nm and a center to center distance of 1,032 ± 175 nm. The chosen fabrication parameters for the pSi film resulted in a pSi layer thickness of 1,503 ± 334 nm, determined from cross-sectional SEM images, and a porosity of 65 ± 9%, obtained by using the spectroscopic liquid infiltration

method (SLIM) [22]. Figure 1 SEM images of the investigated structures. (a) pSi monolayer and (b) pSi monolayer with a non-close packed array of polyNIPAM microspheres on top. Scale bars, 500 nm. In order to study the influence

of selleck products the polyNIPAM microspheres on the optical properties of the pSi layer, interferometric reflectance spectra of porous silicon films with and without polyNIPAM spheres were taken at normal incidence. The fringe patterns, observed in the reflectance spectra, result from the interference of reflected light rays at the boundaries of the pSi film, and the position of the fringe maxima can be calculated using the Fabry-Pérot equation: (1) where m is an integer, λ is the wavelength of the incident light, n is the effective refractive index of the pSi film, and L is its thickness. By applying a fast Fourier L-gulonolactone oxidase transform to the reflectance spectra, the effective optical thicknesses (EOTs, 2 nL) of the porous structures can be directly extracted from the position of the resulting single peak in the frequency spectrum. Changes in the position and amplitude of the FFT peak provide information on the effective refractive index of the pSi layer and the appearance of the involved interfaces, respectively. Hence, a variation in the EOT documents the infiltration of the surrounding medium into the porous layer, and an increase or decrease of the FFT peak indicates variations in the appearance of the porous silicon interfaces, including refractive index contrast and light scattering. This method is referred to as reflective interferometric Fourier transform spectroscopy (RIFTS) [17].

The inconspicuous profile of the theca opening is visible in some cells as “whiskers” at the base of the collar (Figure 5A, arrowheads). Length of the

body is 3–4.5 μm, width – 2 μm (n = 18). The length of the collar is equal to the body length, the flagellum is approx. 2 times longer than the body and the stalk covers up to 3 body lengths. Strain IOW73 was present as sedentary stalked solitary cells and as colonies of 2–4 cells (Figure 6A). The most typical colonies were two cells on a rather long stalk (up to 7 μm). The strain has an elongated vase-shaped cell with a narrow and prominent neck, surrounded Crizotinib with a delicate, tightly enveloping, theca (see ultrastructure) with visible whisker. The body length is 2–4 μm, width – 1 μm (n = 22). The

length of the collar is equal to the body; the flagellum is 1.5-2 times longer than the body. The cell shape of both strains is similar to C. gracilis, studied by Leadbeater and Morton [28]. A contractile vacuole was not visible for cells cultivated at 22 ‰ but appeared when the salinity was reduced to 8–10 ‰ (Figure Akt inhibitor 6A, B). Ultrastructure The electron microscopical investigations revealed an in general typical choanoflagellate cell structure for both strains (Figures 5, 6). As in many others colonial choanoflagellates: (1) the cells were covered with a thin sheath, which envelopes the whole body and the base of the collar (Figures 5A, B, 6B); (2) the collar was composed of approximately 30 microvilli in both isolates (not shown); (3) the Golgi apparatus lies under the base of flagellum (Figure 5B); (4) the flagellar

apparatus has a long transition zone, a flagellar kinetosome with radiating microtubules, and a non-flagellar centriole, all typical for choanoflagellates (Figure 5B, 6D); (5) a nucleus of vesicular type (Figure 6B) is located in the anterior-middle part of the cell; and (6) other organelles and inclusions are also those common for choanoflagellates. Ixazomib Additionally, food vacuoles with bacteria in different stages of digestion were found in the posterior half of the cell, and a contractile vacuole is located at the cell posterior. This latter structure has the typical appearance of a folded reservoir with coated pits and vesicles around it (Figure 6B). Finally, lipid droplets occur in the cytoplasm of some cells (Figures 5D, G, 6C). In contrast to these similarities, the internal structure of mitochondria—the shape of the cristae—is cardinally different from all other choanoflagellates investigated to date. The cells in both strains have mitochondria with tubular or sac-like cristae (Figure 1B including left upper insert, 5F, G, 6B insert lower left). In both types the cristae have tubular or saccular shape (Figure 5B, F, G). In the strain IOW94 mitochondria of two types can be seen: with normal matrix and developed cristae (Figure 5B, F), and with light matrix and rare cristae (Figure 5G).
