The plate reader was controlled by Gen 5 software. The ORAC was determined as described by Ou, Hampsch-Woodill, and Prior (2001), with slight modifications. The reaction was

carried out in phosphate buffer (pH 7.4, 75 mmol L−1): 150 μL of Fluorescein (FL, 40 nmol L−1, final concentration) and 25 μL of free or complexed MGN solutions were placed into the microplate wells and pre-incubated for 15 min at 37 °C, thereafter 25 μL of the AAPH solution (18 mmol L−1, final concentration) were added. The microplate selleck chemical was immediately placed in the reader and the fluorescence was recorded every 1 min for 90 min. A blank with FL and AAPH, using water and ethanol instead of the antioxidant solution, and five calibration solutions using Trolox (0.5, 1.0, 1.5, 2.0 and 2.5 μmol L−1) were

also used in each assay. The inhibition capacity was expressed as Trolox equivalents (mol L−1) and was quantified by integration of the area under the fluorescence decay curve (AUC). The ORAC value was calculated by plotting the net AUC against the concentration as described by Folch-Cano, Jullian, see more Speisky, and Olea-Azar (2010). Unilamellar vesicles of soy phosphatidylcholine (1 mmol L−1) were prepared by extrusion (100 nm pore diameter membrane, at 25 °C) in 10 mL of phosphate buffer (50 mmol L−1, pH 7.4 with the additional incorporation of 0.1 μmol L−1 of the peroxyl-sensitive fluorescent probe C11-BODIPY581/591 as described by Oliveira et al. (2009)). The particle size was confirmed by Nanotrac-Zetatrac, NPA151-31A-0000-D30-10M model being around 100 nm. Fluorescence measurements were carried out at 37 °C using a RF-5301PC spectrofluorophotometer (Shimadzu, Japan). In a 1 mL-quartz cuvette, adequate amounts of the unilamellar vesicle suspension, of the phosphate buffer pH 7.4, and of the sample (100 μmol L−1 MGN or MGN:β-CD complex) or Trolox (100 μmol L−1), as a positive control, were mixed. The β-CD aqueous solution and 4��8C buffer were used

as negative controls. The reaction was initiated with the addition of 100 μL of AAPH (100 mmol L−1). The fluorescence decay (λexcitation = 580 nm, λemission = 600 nm) was continuously monitored over 30 min. The FT-IR spectrum of β-CD (Fig. 2a) showed absorption bands at 3400 cm−1 (for O–H stretching), 2927 cm−1 (for C–H stretching) and 1157, 1082 and 1028 cm−1 (C–H, C–O stretching), as shown in the amplified spectra (Fig. 2b). For MGN (Fig. 2a), absorption bands of the hydroxyl group (3373 cm−1) and C–H asymmetric stretching at 2933 cm−1 were observed, while in Fig. 2b, an aromatic conjugated carbonyl group can be observed at 1651 cm−1 together with signals of aromatic nucleus (1622, 1492 (C C), 1407 cm−1). Bands at 1255 and 1093 cm−1 are attributed to –C–O and C–O–C stretching, respectively (Fig. 2b) (Abu-Yousef, Gunasekar, Dghaim, Abdo, & Narasimhan, 2011). The interaction between MGN and β-CD was confirmed by FT-IR spectroscopy.

These factors enable CD8+ T cells to kill cells displaying pathogen-derived peptides presented by MHC class I molecules, for example a virus-infected cell. By killing cells expressing high levels of virus-derived peptides at

their surface, CD8+ cells are able to eliminate infected cells before the completion of a viral replication cycle, thus limiting viral spread within an infected individual. In addition, CD8+ T cells can http://www.selleckchem.com/products/wnt-c59-c59.html inhibit viral replication without destroying the target cells by producing cytokines that are able to interfere with pathogen replication. CD8+ cytolytic cells can also eliminate cells displaying abnormal host peptides, such as those presented by tumour cells, p38 MAPK assay and therefore play an important role in the immune control of aberrant cell growth. Although CD8+ T cells can directly react to cells expressing the appropriate antigen/MHC class I complexes, their optimal activation

programme (proliferation and acquisition of full cytolytic potential) is best achieved in the presence of cytokines produced by type 1 CD4+ T helper cells. Antibodies represent a highly diverse set of soluble proteins secreted by the subset of lymphocytes referred to as B cells. B cells develop in the bone marrow before undergoing a process of differentiation and maturation in the spleen. As with T lymphocytes, each B lymphocyte expresses a unique antigen receptor (B-cell receptor [BCR]) enabling the cells to react to a specific antigen. In marked contrast to TCRs, BCRs can directly bind to molecules expressed by pathogens, with no need for previous internalisation and presentation by APCs or other innate immune cells. Upon antigen encounter, B cells expressing the cognate BCR are induced to proliferate and differentiate into plasma cells, which can secrete large amounts of a soluble form of the BCR that we know as an antibody. This soluble protein is thus released in the blood Pomalidomide in vivo and other body

fluids (referred to as the ‘humors’) enabling them to fight infection at distant sites. Antibodies play multiple roles in the control and elimination of pathogens, and in the response to vaccination. Binding of targets by antibodies is often sufficient to initiate processes that render the pathogen harmless. Antibodies can be viewed as bifunctional molecules, able to both recognise and eliminate a given antigen or pathogen. Antibody molecules consist of a ‘constant’ fragment, a structural feature common to all antibodies of a given isotype, and a ‘variable’ region, which includes the portion that gives the antigen specificity (or antigen-binding characteristics) of the antibody. The variable region of the antibody can exist in a huge number of molecular configurations, and an individual’s BCR repertoire is generated to maximise capability to produce antibodies that are useful against diverse potential pathogenic threats.

1). There was no evidence of pneumothorax or soft tissue emphysema. After discussing with the surgeons, upper endoscopy under general anesthesia was performed, with patient consent, in the presence of a surgical team. An across located sharp-edged chicken bone (4 cm long) was identified in the mid-esophagus, with bilateral MAPK inhibitor perforation of submucosa and muscular layers with the surrounding area being ulcerated bilaterally. The chicken bone was gently removed with a mouse tooth forceps (Fig. 2) after identification of the shallower end, with immediately drainage of

the abscess onto the esophageal lumen. A 2 cm long midesophageal perforation was visualized. Given the lack of pulmonary symptoms and no evidence of mediastinitis, the team decided on nonsurgical management. To allow further drainage, without blocking with a stent, a nasogastric tube was placed under direct visualization.

The patient was started on broad-spectrum antibiotherapy, proton pump inhibitors and total parenteral nutrition. The control esophagogram (Fig. 3) and computed tomography scan, performed in the day after, revealed a small-contained leak, with no evidence of mediastinic extravasation and no regional signs of infection. The patient was kept on total parenteral nutrition for 8 days, started enteral nutrition on the eighth day and progressed to oral feeding on the twelfth day. The two-week control esophagogram this website revealed no signs of leakage. Patient improved steadily, with normalization of blood chemistry Dynein parameters of infection (C-reactive protein 3 mg/L at discharge), with no in-hospital complications and no complaints of difficulty in swallowing. He was discharged on proton pump inhibitors. Although the primary treatment for esophageal perforation is surgical, endoscopic therapies may play a role and be appropriate in individualized cases. Treatment depends on the etiology, site, and size of perforation, the time elapsed between perforation and diagnosis, underlying

esophageal disease and the overall health status of the patient. Criteria for non-surgical treatment include perforation that is confined to the mediastinum, drainage of the cavity back into the esophagus, clinical stability, and minimal clinical signs of sepsis.10 and 11 Perforation of the cervical esophagus can be managed conservatively in most cases, as well as, perforations of the intrathoracic esophagus that are confined to the mediastinum12; however, perforations of the lower two thirds of the esophagus that affect the pleura, pericardium, or peritoneum require rapid surgical intervention. Choosing an endoscopic therapy for an esophageal perforation requires differentiating between acute and chronic cases.

colitis are recommended to have surgery when a colonic stricture is found. The authors thank Drs. Shinji Tanaka, Ronald Yeh, and Hazem Hammad for their generous contributions. “

” photo Axel Perez/Pleine ouverture Jean-Daniel Picard nous a quittés le 16 décembre 2013. Quelques semaines avant son décès qu’il estimait proche, il m’avait fait parvenir ce qu’il appelait son Journal

où il rappelait les étapes essentielles de sa vie. Jean est né dans une famille juive alsacienne qui était devenue allemande en 1871. Son père, né en Alsace allemande en 1887, avait 8 fils qui normalement auraient dû aller faire leur BYL719 supplier service militaire en Allemagne, mais tous préférèrent s’expatrier et se retrouvèrent en Suisse. Le père de Jean commença des études à l’École horlogère heptaminol de la Chaux-de-Fonds, mais ce travail trop immobile n’était pas fait pour lui. Il se lança dans plusieurs métiers et en définitive devint voyageur de commerce. Quelques années plus tard, il était

devenu un importateur très réputé de vins français, spécialement de Bourgogne, en Suisse. Il se maria à l’âge de 35 ans avec une jeune française modeste dont la mère tenait une mercerie rue de Beaune à Paris. Jean naquit à Lausanne en 1927 puis, pour des raisons essentiellement familiales, ses parents sont revenus vivre à Paris tandis que son père continuait son commerce en Suisse. Jean commença sa scolarité primaire à Paris et ses études secondaires au Collège Chaptal. Puis, la guerre entre la France et l’Allemagne se déclencha et la famille ne put rentrer en Suisse qui avait fermé ses frontières. Tous ses membres se retrouvèrent en Bourgogne alors que Jean allait en bicyclette au lycée de Beaune, mais il avait toujours considéré cette obligation comme une partie de plaisir. La guerre se poursuivant, la famille partit se réfugier à Lyon où Jean continua le lycée. Mais ils furent dénoncés et ce fut la fuite vers le Mont-Dore en Auvergne, puis à Perpignan.

, 2007 and Lundqvist et al., 2010) and ensure irregular low-rate CAL 101 firing (Brunel and Wang, 2003 and Lundqvist et al., 2010). To illustrate the local origin of gamma, the basket cells were demonstrated to fire with a slight delay in time when compared to the pyramidal cells (Fig. 5A), which created the descending slope of the gamma cycle. This preferred phase of firing was not seen (in fact, tests for uniform circular distribution could not be rejected) when the same analysis was performed with the use of spiking activity of basket cells in the neighboring hypercolumns. We

were also interested in the mechanism underlying the relatively broad gamma peak, seen in Fig. 2C and D, when compared to the other distinct frequency components in the power spectrum. For this purpose, we examined the temporal evolution

of the rhythm over the attractor activation period. We found that the dominant gamma frequency was higher at the burst onset and then gradually slowed down (black and red curves, respectively, in Fig. 5B) due to adaptation. We have previously reported that the modularization into distinct hypercolumns with local feedback inhibition significantly increases the stability of persistent oscillatory activity (Lundqvist et al., 2010) through desynchronization of excitatory inputs. Here, we aimed to study how this desynchronization affected long-range coherence in the gamma band. To this end, we applied a moving window approach over entire trials in both simulation paradigms and examined the Ponatinib order average coherence. As expected, strong coherence was found locally within each hypercolumn (Jacobs et al., 2007 and Sirota et al., 2008) whereas between different hypercolumns over distances up Bacterial neuraminidase to 500 μm the coherence was significantly weaker (Fig. 5C) in agreement with experimental findings (Sirota et al., 2008). Further, we increased the conductance of long-range excitation, forming the cell assemblies, to gain insight into the effect of long-range excitatory connections on the synchronization of distant minicolumns. As a result, a considerable

difference between the lowest and the highest level of long-range excitation tested in our simulations was observed (Fig. 5D, shown only for memory pattern completion) with higher coherence for lower excitation. This was likely due to the shorter attractor dwell times for low excitation configurations. When CaNMDACaNMDA influx rate was reduced in such a manner that attractors were stationary (see Experimental procedures), coherence dropped overall by ~0.1 (dotted line in Fig. 5D). In order to examine whether coherence accounted only for amplitude covariance, we estimated local and global phase locking in the gamma band. As expected, we found locally strong phase locking close to 1 (Fig. 5E), with essentially all firing events occurring at a specific phase of the gamma cycle (Fig. 8A), as observed experimentally (Jacobs et al., 2007 and Sirota et al., 2008).

Both ANP and BNP are abundantly expressed in the heart and are secreted mainly from the atria and ventricles, respectively.

However, CNP is mainly expressed in the central nervous system, bone and vasculature (Nishikime et al., 2010 and Tobias, 2011). Classically, the clearance of all NPs is carried out by NPR-C and by the neutral endopeptidase (NEP); both of learn more these proteins are widely expressed in the kidneys, lungs and vascular walls (Chen and Burnett, 2006). The three mammalian NPs have been extensively investigated for use as therapeutic agents in the treatment of cardiovascular diseases. Over almost 30 years of research, NPs have been found in mammals, amphibians, reptiles, fish, and in plants. Recently, they have also been found in bacteria (Vink et al., 2010). The first natriuretic peptide isolated from animal venoms was a vasorelaxant peptide. This 38 amino acid residue peptide was isolated from green mamba venom and named dendroaspis natriuretic peptide (DNP). Many natriuretic peptides have subsequently been isolated from snake venoms, including Brazilian snakes, such as Crotalus durissus cascavella ( Evangelista et al., 2008), Bothrops jararaca ( Higuchi et al., 1999), Bothrops Doxorubicin nmr moojeni ( Menin et al., 2008) and Lachesis muta ( Soares et al., 2005). Many genes encoding C-type natriuretic peptides have also been described ( Harvey,

2006). Scorpion venoms are rich sources of small peptide toxins. However, no natriuretic peptides have been isolated from scorpion venom thus far. However, a new family of peptides, called hypotensins, has been isolated from the venom of the yellow scorpion, Tityus serrulatus. These toxins share a similar amino acid signature with the bradykinin-potentiating peptides (BPPs) found in snake venoms ( Verano-Braga et al., 2008 and Verano-Braga et al., 2010). In snakes, BPPs and CNP are encoded by the same gene ( Assakura et al., 2000). This work describes the isolation, sequencing and tridimensional homology modeling of the first C-type natriuretic peptide from scorpion venom. Its effects on the

renal function of rats and the mRNA expression of the natriuretic peptide receptors in the kidneys were also evaluated. T. serrulatus venom was acquired from the Instituto Butantan (São Paulo, Brazil). All salts and reagents were of analytical grade dipyridamole and were obtained from certified suppliers. Crude T. serrulatus venom (35 mg) was dissolved in 1.0 mL of ammonium bicarbonate buffer (1 M, pH 8.0). The solution was centrifuged at 4500 × g for 10 min and the supernatant was filtered with a 0.22 μm PVDF filter membrane. Then, 300 μL of the venom solution was loaded onto a Superdex® Gel Filtration Column Peptide HR10/300 GL coupled in a semi preparative Jasco HPLC system (Easton, MD, USA). This column was equilibrated with ammonium bicarbonate buffer (0.25 M, pH 7.8) for 40 min before sample application.

The figures presented are shown with ± one standard deviation. KP did not demonstrate any decrements in intellectual function or memory following surgery for her right-hemisphere cavernoma, when tested 15 weeks after

surgery (see Table 1). There were no significant changes in focal cognitive ability, except a very mild decline in her performance on the Symbol Digit Modalities Test, on which she was considered borderline impaired, whereas she had previously been Dabrafenib in vivo average. KP was tested once on the STOP task, on the second occasion we saw her (Table 1). The SSRT provides an estimate of the time required for an individual to correctly inhibit an initial response on 50% of trials. On this task KP’s SSRT (150 msec) was not significantly different (t = −.78; p > .22) to the control group (mean = 177 msec, SD = 32.1; Fig. 3A). KP’s leftward SSRT was longer than rightwards (12 msec), but this deviation was not significantly different to the controls (t = .29; p > .39) who also showed slightly greater leftward slowing (7.3 msec, SD = 15.4). In terms of GO reaction

time, KP (532 msec) was not significantly different to the control group (mean = 434, SD = 114.3; t = .82). She demonstrated virtually no lateralisation in GO reaction time, being only 2 msec quicker when making leftward responses. This was not significantly different to the control group (t = −.14; p > .45), who overall were slightly slower when making leftward responses (5 msec, SD = 20.9). Thus, KP’s performance on the STOP task was entirely within normal Omipalisib order limits when assessed (Session 2, S2). KP was tested three times on the CHANGE task over the course of 10 weeks (see Table 1). Performance on this paradigm uses a similar metric to the STOP-signal paradigm, however here the CHANGE-signal reaction time (CSRT) reflects the time

taken to inhibit an initial response and then correctly execute a second response on 50% of trials. In the first session (S1), four weeks after surgery, KP’s CSRT (382 msec) was significantly higher (t = 2.85; p < .01) than the control group (mean = 268 msec, SD = 37.7), see Fig. 3B. KP also demonstrated a highly significant lateralisation in CSRT (t = 2.6; p < .005; paired-samples t-test), with leftward CSRT 46 msec slower than rightward. This lateralisation was significantly different to the 3-oxoacyl-(acyl-carrier-protein) reductase control group (t = 2.61; p < .028), who demonstrated a leftward slowing of only 6 msec (SD = 4.6). Both leftward and rightward CSRT measurements were still highly significantly different to the controls (t = 3.05; p < .007). Importantly, in terms of GO reaction time KP (mean = 435 msec) was not significantly slower than the control group (mean = 395 msec, SD = 160.1; t = .24). She did demonstrate an increased latency in responding to leftward GO signals (11 msec), but this was also not significantly different to the controls (t = −.17) who showed a similar lateralisation (mean = 14.9 msec, SD = 21.9).

The most recent generation of FADs are equipped with echosounders that transmit daily or hourly estimates of biomass beneath the buoy, allowing skippers to confirm the presence of a school beneath a FAD before visiting it, and in some oceans (e.g. Atlantic and Indian oceans), auxiliary supply vessels are allied with purse seine skippers and used to deploy and monitor FADs using sonar and other fish-finding technologies [5]. Whilst FADs are evidently useful fishing tools, their use has been associated Selleckchem Ipilimumab with several potential negative ecosystem impacts, including catch of juvenile tunas and bycatch of vulnerable non-target

species [6], [7] and [8]. Furthermore, there is concern that the highly efficient practice of FAD fishing, if left unchecked, might exacerbate

issues of overcapacity and ultimately lead to the unsustainable exploitation of tuna stocks [2] and [9]. There is currently little control on the use of FADs in purse seine fisheries and there has been increasing discussion within tuna Regional Fisheries Management Organisations (tRFMOs) on managing their use more strictly [9]. So far, this discussion has served mainly to highlight uncertainties in our understanding of the sustainability of catches on FADs and the consequences of modification of the pelagic habitat on tuna biology but has also begun to tentatively explore the impact of potential management acetylcholine solutions on purse seine catches [9], [10], [11] and [12]. Consideration of potential management must also consider Selleckchem Roxadustat how fishers will respond to the introduction of management measures [13] and [14]. It is widely recognised

that designing fisheries management with the behaviour of fishers explicitly accounted for can reduce the risk of implementation error, i.e. where management outcomes deviate from those intended [15]. In considering how purse seine fleets will respond to controls on the use of FADs it is necessary to have an understanding of the role FADs play in fleet dynamics, from long term trends in fleet characteristics to how effort is allocated in space. Yet, despite the importance of understanding the role of FADs in driving these dynamics, to date this topic has received much less attention than the ecological issues associated with the use of FADs. This paper characterises the past and present use of FADs in the Indian Ocean tropical tuna purse seine fishery. First, the potential ecological impacts of FADs are summarised (see [5] for a full review). Next, the role of FADs in the development of the Indian Ocean purse seine fishery is discussed, spatio-temporal patterns in their use are characterised, and their influence on effort allocation dynamics is examined.

The intermediate washing steps with PBS-T and developing were as described earlier using AP substrate. Background was assessed by incubating the wells with the non-induced periplasmic extract. All assays were conducted in duplicate. We used a rapid dot-immunoblotting protocol. Volumes of 10 μl of sera samples from Toxoplasma sero-negative and sero-positive

patients KU-57788 supplier were spotted onto nitrocellulose membrane, allowed to air dry and then blocked with blotto. The membrane was incubated for 1 h at room temperature with a periplasmic preparation containing the SAG1–AP fusion protein. Specific immunocomplexes were detected by incubation for 20 min in the BCIP/NBT AP substrate buffer. The membrane was washed three times with PBS-T between each step. Background learn more was assessed in the same conditions with the non-induced periplasmic extract. According to the primers used, sag1

coding gene fragment was PCR-amplified as 867 bp including SfiI/NotI clamp sequences (data not shown). After digestion with restriction enzymes, DNA fragment was ligated into the SfiI/NotI cloning site of the pLIP6-GN vector. The recombinant plasmid was transformed into the E. coli DH5α strain; rapid visual screening on BCIP containing agar plates allowed detection of recombinant clones and the corresponding plasmids were sequenced. As expected in all blue colonies, insertion of the sag1 gene between codons + 6 and Ureohydrolase + 7 of AP gene restored the initial frame of the AP gene in the vector. In the retained plasmid, nucleotide and deduced amino acid sequences of sag1 were in agreement with GenBank database (accession no. X14080) (data not shown). The recombinant pLIP6-sag1–AP vector was subsequently used to transform E. coli XL1-blue strain. The colonies were grown in LB medium at 37 °C, and then induced with 0.5 mM IPTG at 28 °C overnight. Periplasmic fusion protein was extracted using cold osmotic shock. A protein band with an apparent molecular weight of 78 kDa

was detected after SDS-PAGE on homogenous 10% silver staining gel ( Fig. 1A, lane 2), in agreement with the SAG1–AP predicted molecular mass. This band was absent in the non-induced cell culture. The identity and the integrity of this band as the SAG1–AP conjugate were confirmed further by two Western blotting after SDS-PAGE. The first was revealed with the anti-bacterial AP MAb ( Fig. 1B) and detected the 78 kDa-recombinant protein in periplasmic and cytoplasmic fractions from induced recombinant bacteria tested. The second blot was revealed with the conformational anti-T. gondii SAG1 Mab ( Fig. 1C) and only the periplasmic SAG1–AP was detected. This means that the intact SAG1–AP fusion protein was released in soluble form into the bacterial periplasm, where the SAG1 antigen adopts a native-like structure. No visible degradation products are revealed using anti-SAG1, suggesting the stability of the fusion protein.

Under an Ohio State University IACUC-approved protocol, sixty-four female (47 day old) rats of equivalent weights were divided into four groups (16 per group): 2 control and 2 treatment groups.

Controls were fed a semi-synthetic diet containing 0.6% calcium and 0.6% phosphorus as published elsewhere [24] for 2 or 4 weeks and β-APN treated animals were fed a diet inclusive of β-aminopropionitrile (0.1% dry weight) for 2 or 4 weeks . The 2 and 4 week-time points were used to allow formation of new bone with varying degrees of cross-linking in limited anatomical areas, without affecting the whole bone. Rats were sacrificed at the assigned time points and intact spines were harvested, dissected free from soft tissue

and stored in 70% ethanol. L3 vertebra from each animal were Erismodegib cost equilibrated Talazoparib nmr with phosphate buffered saline, pH 7.8, pulverized and reduced with KBH4 for 1 h. After this time, the pH was adjusted to 4 with acetic acid to destroy excess reagent, the tissue washed extensively with water and freeze dried. The reduced bone was hydrolyzed in 6 M HCl at 107 °C for 22 h and the acid was removed by evaporation. Following preliminary fractionation of cross-linked amino acids by partition chromatography, the intermediate compounds (DHLNL and HLNL) were assayed by ion-exchange chromatography with post-column derivatization and the mature bonds (PYD and DPD) were quantified using RP-HPLC using

their natural fluorescence, as described previously [25]. Cross-link concentrations were expressed relative to collagen content determined by colorimetric measurement of hydroxyproline in the original hydrolysate. It should be noted here that both cortical and trabecular bone were included in the analysis. The endplates of each L2 vertebra were carefully removed with a low speed diamond-coated saw (Isomet, Buehler, Germany) to provide samples with a height of approximately 3 mm. The vertebral Ponatinib datasheet body was then isolated from the posterior elements and one of the plane surfaces was glued on a carbon rod with a thin layer of cyanoacrylate glue. The other surface was polished to achieve parallel faces. The average final height was 2.5 mm. The vertebral body was scanned in 70% ethanol by μCT with a 12 μm voxel size (μCT40, Scanco, Switzerland). The reconstructions were segmented with an optimal threshold, separated into trabecular and cortical compartments and standard histomorphometric parameters were computed with the manufacturer’s software (IPL, Scanco, Switzerland). Vertebrae (L5) were fixed in 70% ethanol, dehydrated through a graded series of ethanol and embedded undecalcified in polymethylmethacrylate (PMMA). About 5 millimeter thick blocks containing a sagittal vertebral bone section were cut using a low speed diamond saw (Buehler Isomed, Lake Pluff, USA).
