, 2003, Xu et al., 2003 and Shu et al.,

2012). This macrophage proliferation, coupled with increased TLR4 and other pattern recognition receptors on adipocytes, leads to an increase in the pro-inflammatory cytokine profile (Hotamisligil et al., 1993, Hotamisligil et al., 1995, Uysal et HDAC inhibitor al., 1997 and Shu et al., 2012). Increased pro-inflammatory cytokines, adipokines, and fatty acids then have downstream effects on liver and muscle, which contribute to systemic insulin resistance (Shu et al., 2012). Pro-inflammatory cytokines, such as tumor necrosis factor (TNF)α activate serine kinases that directly and indirectly phosphorylate insulin receptor substrate (IRS) 1 and 2, resulting in a reduced ability of insulin to stimulate phosphatidylinositol-3 kinase (PI-3K)-dependent pathways that normally result in glucose uptake and metabolism (Hirabara et al., 2012). Feeding-related pathways in the hypothalamus are also disrupted by inflammation, with insulin and leptin less able to suppress hunger and feeding, further contributing to the maintenance of a high fat diet and thus obesity find more (Thaler and Schwartz, 2010). Obesity- and high fat diet-associated systemic inflammation was identified some time ago, with early reports suggesting obese humans and high fat diet-fed rodents

have elevated circulating pro-inflammatory cytokines compared with controls, and macrophage infiltration into the WAT (Pickup and Crook, 1998, Weisberg et al., 2003 and Wellen and Hotamisligil, 2003). The suggestion that obesity can also result in central inflammation, however, Teicoplanin is a relatively recent one. In 2005, de Souza and colleagues showed high fat diet elevates the expression of pro-inflammatory cytokines and activation of the pro-inflammatory

transcription factor nuclear factor κB (NFκB) in the hypothalamus (De Souza et al., 2005). Several other investigations followed, suggesting high fat diet can cause hypothalamic inflammation and that this inflammation can interrupt normal feeding- and metabolism- related signaling. Thus, high fat feeding leads to infiltration and activation of microglia (the brain’s resident macrophages) in the hypothalamus, activation of inflammatory signaling, and increases in local inflammatory mediators such as cytokines (Fig. 1) (De Souza et al., 2005, Zhang et al., 2008, Milanski et al., 2009, Posey et al., 2009 and Thaler et al., 2012). Importantly, this central inflammation can actually contribute to leptin and insulin resistance, favoring weight gain and maintaining an elevated body weight (De Souza et al., 2005 and Posey et al., 2009). As with systemic increases in pro-inflammatory cytokines, increases in TNFα, IL-6 etc.

Die Plasma- und Serumzinkspiegel sind leicht zugängliche Messwerte, physiologisch aber nicht aussagekräftig, da sie den zellulären Zinkstatus nicht

unbedingt wiedergeben [36], [45], [101] and [102]. So blieben z. B. die Plasmakonzentrationen über mehrere Wochen bis Monate innerhalb des allgemein anerkannten Normalbereichs, obwohl mit der Nahrung nur 2,6 bis 3,6 mg/Tag (40 bis 55 μmol/Tag) zugeführt wurden [36] and [103], Zinkmengen, die für eine intakte neurobiologische Funktion [104] inadäquat sind. Der Zinkgehalt von Leukozyten oder Lymphozyten spiegelt den SGI-1776 Zinkstatus und damit assoziierte Funktionen, wie z. B. Wachstum in allen Stadien des Lebenszyklus und Immunität, wesentlich genauer wider als der Plasmazinkspiegel [105]. So war z. B. der Zinkgehalt in Leukozyten und nicht der im Plasma ein Indikator für das Wachstum des Fetus und darüber hinaus auch abhängig von der Muskel-Zinkkonzentration bei der Mutter [87]. Die Ecto-5’-Nukleotidase-Aktivität ist bezüglich des Zinkstatus empfindlicher als die Plasma-5’-Nukleotidase-Aktivität oder der Plasmazinkspiegel [106], [107] and [108]. Ein konzeptionell unterschiedlicher Ansatz stützt sich auf die Expression zinkabhängiger

Gene in Lymphozyten als Biotest auf den Zinkstatus [109]. Die Autoren beobachteten, dass bei einer Supplementierung mit 22 mg/Tag Zinkgluconat über 27 Tage die Expression des zellulären Zinktransporters hZip1 um 17% zurückging. Das Verhältnis zwischen CD4+- und CD8+-T-Lymphozyten wurde als robuster www.selleckchem.com/products/byl719.html immunologischer Test auf einen Zinkmangel vorgeschlagen [110]. Darüber hinaus inaktiviert schon ein sehr milder Zinkmangel das Peptidhormon Thymulin, da die Zinkonzentration in diesem Fall für eine Bindung an das Hormon nicht mehr ausreicht. Dies führt zu einer Beeinträchtigung

der Immunität ohne gleichzeitige Thymusatrophie [111], die eine Manifestation das Zinkmangels ist [112]. Thymulin vermittelt die T-Zell-Differenzierung und verschiedene Funktionen von T-Zell-Subpopulationen [113]. Niedrige Thymulinaktivitäten im Plasma wurden bei älteren Personen mit normalem Plasmazinkspiegel, Fludarabine in vivo aber niedrigem Zinkgehalt in Leukozyten festgestellt [114]. Metallothionein in menschlichen Erythrozyten spricht auf Zinksupplementierung (50 mg/Tag) und beschränkte Zinkzufuhr mit der Nahrung an [115]. Ein Zinkmangel kann auch anhand von Effekten einer Zinksupplementierung auf physiologische Funktionen gemessen werden. In der Labormedizin gehen auffällige klinisch-chemische Messwerte oft den funktionellen und körperlichen Anzeichen einer Erkrankung voraus. Dies gilt jedoch nicht für den Zinkspiegel im Plasma (oder Serum), den am häufigsten bestimmten Indikator für den Zinkstatus. Funktionelle Effekte können u. U.

By the end of the time period, simulation M2M2-tight has values of ΔEb′ within 5% of the high resolution fixed mesh simulation F-high1 whilst using one order of magnitude SCH772984 fewer vertices. Simulation M2M2-tight therefore offers an improvement in Eb′ over M2M2-mid but has an increased computational cost.

The diapycnal mixing behaviour and distribution of vertices indicate that it is the ability of M2M2 to increase resolution even when the curvature is weaker that allows the improved representation of the field and the reduction in the diapycnal mixing. Snapshots of the mesh for simulation M∞M∞-var and M2M2-mid show higher resolution of the billows, particularly at their centre, and also extending away from the billow edges, Fig. 3 and Fig. 5. As the fluid in the billow begins to mix and the fields homogenise, the curvature of the fields is reduced (particularly in the temperature field). The smaller-scale variations in the fields are not captured adequately in the simulation with

M∞M∞ but are given more weight in M2M2 and, hence, are better represented. Furthermore, during the oscillatory stages, the simulations that use M∞M∞ have Selleck ABT 199 much coarser resolution in the majority of the domain than simulation M2M2-mid, Fig. 3 and Fig. 5. It is not surprising, therefore, that simulation M2M2-mid behaves more like the higher resolution fixed meshes and demonstrates that M2M2 provides a better guide of where the mesh resolution is needed. The values of the no-slip and free-slip Froude number tend to near constant

values as the fixed mesh resolution increases, Fig. 9. The no-slip values for the two higher resolution simulations, F-high1 and F-high2, are affected by the shedding of a billow at the nose of the gravity current; this results in an acceleration and deceleration of the front and is captured by the large error bars for these values (cf. Hiester et al., Thymidine kinase 2011). For F-high2 only part of the acceleration/deceleration occurs within the window over which the values of Froude number are calculated and, therefore, the average value is slightly over-estimated (Hiester, 2011). The values of the Froude number for simulations with MRMR and M2M2 show good agreement with the fixed meshes and M∞M∞-var, Fig. 9. Simulation M2M2-loose presents the best performance for the Froude number diagnostic, compared to both the fixed meshes and other adaptive meshes. The next best performing adaptive mesh simulation is M2M2-mid, followed by M∞M∞-var. Only simulation M∞M∞-const significantly under performs. An increase in boundary resolution ahead of the gravity current fronts can be seen in the mesh for simulations with M2M2 and MRMR, Fig. 5.

Each set of data contains multiple-year observations of soil and runoff loss under widely varied rainstorms, which are typical to semi-arid climates. With an increase of slope angles, runoff per unit area slightly increased on

SSP, but it decreased after reaching a maximum at 15° on LSP, which may be related to the complicated effect of several factors (e.g. crusting, rill development, rainfall conditions) on soil infiltrability. Soil loss per unit area increased with slope angles on both SSP and LSP. There were 36.4% less runoff but only 3.6% less soil loss per unit area produced on LSP than on SSP, which selleck chemicals was likely ascribed to more runoff infiltration and greater flow velocity on long slope as a comparison of short slope. Event recurrence interval is a better rainfall index than event rainfall amount in correlating rainfall to soil loss and runoff. The correlation between soil loss and recurrence interval can be best fitted with a linear equation on SSP and a polynomial equation on LSP. Storms with recurrence intervals greater than 2 years contributed to about two thirds of the total runoff and soil loss. Z-VAD-FMK The slope equations in USLE/RUSLE overestimated the S factor in this region.

On the steep cropland, a fraction of annual precipitation was often responsible for majority of annual total erosion in this semi-arid region. In general, the soil conservation practices were more effective in reducing soil loss than in reducing runoff on steep cultivated croplands. The five conservation practices (earth banks,

woodland, alfalfa, terrace and grassland) generated 123.8%, 118.9%, 111.0%, 30.3% and 15.2% of the mean annual runoff on cropland, and correspondingly yielded 48.9%, 25.1%, 10.6%, 6.9%, and 6.4% of mean soil loss on cropland. The effectiveness of soil erosion control in storms greater than 2 years in recurrence intervals decreased in the order of terraces > grasses > woodland > alfalfa > earth bank, while the effectiveness in reducing runoff caused by storms greater than 10 years in recurrence intervals decreased in the order of grasses > terraces > woodland > earth banks > alfalfa.

“Perth, located on the west coast of Western Australia (Fig. 1), is Australia’s fourth most populous (∼2 million people) city and experiences a Mediterranean-type climate, dominated by wet winters and relatively dry summers.

Samples were tested at three different concentrations (5, 15 and 30 μg/mL). Three cell culture flasks were used for each concentration/experiment totalizing 6 different volunteers. The mutagenic potential on human cell cultures was analyzed for B. jararacussu, B. alternatus, B. atrox, B. moojeni and B. brazili crude venoms and isolated toxins (BthTX-I,

BthTX-II, BjussuMP-II and BatxLAAO). The samples were added 24 h after the initiation of the cultures. After 44 h, cytochalasin-B (4 μg/mL, Sigma) was added to the cultures. The CBMN test preparations were performed according to Fenech and Morley, 1985a and Fenech and Morley, 1985b. The analyses were carried out after 72 h. Scores were taken according to the criteria of Fenech (2000). All slides

were coded and scored blindly. Three slides were made for each flask/treatment/experiment, MDV3100 in vivo and 1000 binuclear cells were counted considering the presence or absence of micronuclei, this way making it possible to determine the genotoxic effect of venoms or isolated toxins. Based on the values obtained for the controls that contained only cells and culture media, in which the micronuclei formation mean was of approximately 1.0, mean values higher than 2 micronuclei/1000 binuclear cells (MN/1000 BN cells) were considered significant for the assayed samples. The antineoplastic drug, Cisplatin (PLATINIL®, Quiral Química do Brasil S.A.) (6 μg/mL) was used as positive control. The cytokinesis-block proliferation index (CBPI) was calculated by counting 500 cells, considering the number of nuclei (mono, bi, tri or tetranucleated). The CBPI defines whether the Everolimus concentration cultures are multiplying normally after the addition of samples. The following formula was used according

to Kirsch-Volders (1997): CBPI = [1 (mono) + 2 (bi) + 3 (tri + tetra)] / 500. This test was performed according to the methodology described by Singh et al. (1988). The lymphocytes were cultured in total blood obtained from 6 healthy volunteers and each one corresponded to one experiment. The concentration and incubation times were performed according to Marcussi 3-mercaptopyruvate sulfurtransferase et al. (2011). Three cell culture flasks were used for each treatment/experiment, and the culture period was of 7 h at 37 °C. The cells were incubated with different treatments for 4 h at 37 °C, and were then utilized to prepare the slides before the first cellular division. A cellular suspension containing approximately 105 cells/mL was used to obtain 5–8 million cells per slide. Three slides were made for each flask of each treatment/experiment, although only 100 nucleoids were evaluated per flask/treatment/experiment-volunteer, totalizing 300 nucleoids/treatment/volunteer. Approximately 60 μL of each cell culture were transferred to microtubes containing 300 μL of LMP (low melting point) agarose, for the slides preparation in triplicate.

1 ± 0.05 μmol g−1) (Fig. 1). The highest concentration of GL was found in the stalks of organic broccoli (1.5 ± 0.4 μmol g−1); this value is similar to values

reported by Aires, Galunisertib research buy Rosa, and Carvalho (2006). However, the GL stalk concentration is considerably higher than those reported by Song and Thornalley (2007), which resembled the concentrations we observed in inflorescences. Some authors have attributed these differences to the type of cultivation, soil conditions, climate, humidity, photoperiod and several other environmental factors (Fahey et al., 2001). The high glucosinolate concentration found in this present study could be due to the extraction medium, which contained TFA. Data reported by other authors (Song & Thornalley, 2007) utilized an extraction method conducted with pure methanol. This hypothesis is supported by the data shown in Fig. 1, which compares the extraction of GL with and without TFA. Another possibility for the discrepancy is the time period used for calculating thioglucosidase activity (24 h). This time check details duration was optimized for complete GL hydrolysis, and this may have led to the

generation of increased amounts of glucose, the product of the hydrolysis reaction. These data are interesting, and we verified some differences in glucosinolate concentrations among different plant parts. We also considered the vegetable parts that are usually discarded by consumers. Some of the discarded plant tissues contain the highest concentration of these substances, which have been reported to have possible positive effects on human health (Tang and Zhang, 2005 and Hu et al., 2006). Furthermore, our data suggest that plants cultivated in accordance with organic procedures can be promising sources for elucidating the metabolic synthesis pathways of glucosinolates and for extracting bioactive and natural compounds for industrial use. The data reported in Fig. 1 show that no significant differences in GL content were observed among various morphological

parts of the broccoli grown under conventional cultivation. Furthermore, as first reported by Song and Thornalley (2007), the cooking process did not significantly decrease the total GL content in these conventionally cultivated vegetables. However, this result is controversial and has been discussed by Vallejo, Tomas-Barberan, and much Garcia-Viguera (2002). This present work noted a significant decrease in the GL content of organic broccoli following simulated cooking. According to Song and Thornalley (2007), cooking affects glucosinolate composition and content in Brassica vegetables; these changes in composition depending on the processing manner, cooking time, vegetable type and damage to vegetable tissues. In our study, cooking time was short (5 min) and minimized the loss of these compounds from conventional vegetables. However, inactivation of myrosinase and tissue damage by the boiling water treatment may have affected the organic broccoli.

C11, PCP and DMA (Fig. 1a) were initially assayed for their click here ability to inhibit the kinase activity of CK2. As shown in Fig. 1b and summarized in Table 1, C11 inhibited both the CK2α subunit (IC50 4.96 μM) and CK2 holoenzyme (IC50 4.64 μM) in the low micromolar range. In the case of PCP, the IC50 was 3.73 μM and 1.99 μM for CK2α and CK2 holoenzyme, respectively. DMA did not exert

any inhibitory effect on both enzymes indicating that PCP is the active component in the C11 mixture. Further, a kinetic analysis was performed with two different PCP concentrations (i.e. 1 μM and 10 μM, respectively) in order to address the mechanism by which CK2 is inhibited by the aforementioned compounds. As shown in Fig. 1c and Table 1, Km values increased concomitantly to increasing concentrations of Protease Inhibitor Library order PCP, moreover, the double reciprocal plots indicated that the inhibition is consistent with an ATP-competitive binding

of the enzyme. We performed a WST-1 viability assay with two human pancreatic cancer cell lines, i.e. Panc-1 and MIA PaCa-2, for studying the effects of treatment with C11 and its individual components. As shown in Fig. 2a, incubation of cells with increasing concentrations of C11 or PCP for 48 h resulted in progressive cytotoxicity in both cell lines. Similar effects, albeit less pronounced, were obtained when PCP and DMA where combined in a 1:1 ratio. Incubation of cells with DMA alone did not result in reduced metabolic activity indicating that PCP is the component within C11 responsible for the reduced metabolic activity of the cells. A subpopulation of cells within the Panc-1 cell line exhibits features of cancer stem cells (CSCs) such as extensive self-renewal, proliferation, tumorigenesis and high chemoresistance

[19] and [20]. Thus, we asked the question whether PCP induced cytotoxic effects also in this fraction of cells by performing a WST-1 assay. Panc-1 cells were enriched in CSCs expressing the cell surface markers CD44 and CD24. The percentage of CD44+/CD24+ cells was determined by flow cytometry showing an increase from 4.35% to 23.33% (Fig. 2b). A batch of Panc-1 Olopatadine cells as well as a population of depleted and enriched CSCs were left untreated or exposed to C11 and PCP, respectively, for 48 h. Data reported in Figure 2c show that PCP is toxic to all cell populations in a dose dependent manner and independently of the stem-like properties of the cells. Next, flow cytometry analysis was performed to measure the percentage of cells in sub-G1 indicative of cell death, in response to C11 and PCP treatment, respectively, (Fig. 3a). Cells were left untreated or incubated with 100 μM C11, PCP and DMA for the indicated time, respectively. In Panc-1 cells, 72 h incubation with C11 and PCP resulted in 23% and 29% of hypodiploid cells (fraction of cells in sub-G1), respectively.

This way, the generated

damage extent and oil outflow calculations are used primarily to learn the parameters in the BBN in realistic areas of the impact scenario space. A direct, uncorrelated sampling of yT, yL, l and θ would lead to a large number Selleckchem ABT-199 of cases in unrealistic areas of the impact scenario space, which is unnecessary in actual applications. The ranges for the impact scenario variables in the MC sampling are shown in Table 2. The resulting data set from which the Bayesian submodel GI(XI, AI) is learned consists of following variables for all damage cases: • Vessel particulars: length L, width B, displacement Displ, deadweight DWT, tank type TT, number of side tanks ST and number of center tanks CT, see Fig.

3. Learning a Bayesian network from data is a two-step procedure: structure search and parameter fitting, for which a large number of methods have been proposed (Buntine, 1996 and Daly et al., 2011). In the presented model, use was made of the greedy thick thinning (GTT) algorithm (Dash and Cooper, 2004) implemented in the GeNIe free modeling software.4 The GTT is a score + search Bayesian learning method, in which a heuristic search algorithm is applied to explore the space of DAGs along with a score function to evaluate the candidate network structures, guiding the search. The GTT algorithm discovers a Bayesian network structure using a 2-stage procedure, given an initial graph

G(X, A) and a dataset T: I. Thicking GSI-IX step: while the K2-score function (Eq. (12)) increases: The above algorithm starts with an initial empty graph G, to which iteratively arcs are added which maximize the K2-score function in the thicking step. When adding additional arcs does not lead to increases in K2-score, the thinning step is applied. Here, arcs are iteratively deleted until no arc removal results in a K2-score increase, which is when the algorithm is stopped and the network returned. The oxyclozanide K2-score function is chosen to evaluate the candidate network structures (Cooper and Herskovits, 1992). This method measures the logarithm of the joint probability of the Bayesian network structure G and the dataset T, as follows: equation(12) K2(G,T)=log(P(G))+∑i=1n∑j=1qilog(ri-1)!Nij+ri-1!+∑k=1rilog(Nijk!)where P(G) is the prior probability of the network structure G, ri the number of distinct values of Xi, qi the number of possible configurations of Pa(Xi), Nij the number of instances in the data set T where the set of parents Pa(Xi) takes their j-th configuration, and Nijk is the number of instances where the variables Xi takes the k-th value xik and Pa(Xi) takes their j-th configuration: equation(13) Nij=∑k=1riNijk In the construction of the submodel GI(XI, AI) through Bayesian learning, two preparatory steps are required to transform the oil outflow dataset from Section 4.3.2 in a BN.

Grade 3 complications were infrequent, and all such cases eventually had resolution of these effects with minor surgical intervention. It is important to note that no severe GI complications were encountered in this cohort, despite having had previous very high doses of EBRT. Local recurrence after definitive EBRT is not infrequent. It has been estimated that nearly one-third of patients who undergo EBRT will have positive post-treatment biopsies of the prostate, and 15% of patients who received 8100 cGy were

found to have positive biopsies (9). The consequences of locally recurrent disease after radiotherapy can be significant. In a report of the outcomes of locally see more recurrent prostate cancer after EBRT, Kuban et al. reported that nearly one-third of patients suffered from major complications associated with

local recurrence (10). Locally recurrent diseases pose as well a significant risk for the development of distant metastases [1], [9] and [11]. http://www.selleckchem.com/products/BI6727-Volasertib.html Often patients who have developed locally recurrent disease after radiotherapy are not candidates for salvage prostatectomy due to age or coexisting medical comorbidities. Salvage prostatectomy also carries a significant risk of rectal injury (16–58%), and 68% of patients will require the use of at least one pad for urinary incontinence (12). Long-term followup suggests that up to 54% of patients who undergo salvage prostatectomy will achieve biochemical control of their disease (13). The use of other salvage modalities such as cryoablation after failed radiotherapy has been reported. In a large study of quality of life, 72% of patients reported incontinence at a median of 17 months, and two-thirds of patients

reported significant urinary symptoms (14). Rectal injury rates of 2% and incontinence rates between 4% and 8% have been reported. The fistula rate was 3.4% (15). In a large study of salvage cryotherapy, 17% of patients were noted to positive biopsies after treatment (16). Therefore, effective treatment options without significant morbidity in the setting of locally Fossariinae recurrent prostate cancer after radiotherapy are limited. The results of low-dose-rate salvage brachytherapy have also been reported. Reports published over 10 years ago [17] and [18] have indicated that while tumor control can be achieved with low-dose-rate salvage brachytherapy in 30–50% of patients, toxicity outcomes were increased possibly related to the use of less sophisticated planning techniques or the selection of less optimal patients based on the presence of baseline symptoms. More recently Chen et al. (7) have described preliminary outcomes of MRI-based partial prostate salvage low-dose-rate brachytherapy in 15 patients with a median followup of 23 months (8–88 months), with no cases of Grade 3 or higher GU complications. Biochemical control was achieved in 73% of patients at 3 years. Aaronson et al.

1% trifluoroacetic acid (TFA) in water (solvent A), and acetonitrile and solvent A (9:1) as solvent B. The separations were performed at a flow rate of 1 mL/min using a Shim-pack VP-ODS C-18 column (4.6 × 150 mm) and a 20–60% gradient of solvent B over 20 min. In all cases, elution was followed by ultraviolet absorption (214 nm). The scissile bonds in the peptides were determined by mass spectrometry analyses. The peptide fragments were detected by scanning from m/z 100 to m/z 1300 using an Esquire 3000 Plus Ion trap Mass Spectrometer with ESI and esquire CONTROL

software (Bruker Daltonics, MA, USA). Purified 18O-labeled or unlabeled oxidized W derivatives were dissolved in a mixture of 0.01% formic acid:acetonitrile (1:1) and infused into the mass (direct infusion pump) spectrometer at a flow rate of 240 μL/h. The skimmer voltage of the capillary was 40 kV, the dry gas was kept at 5.0 L/min, and the source this website temperature was maintained at 300 °C. After defining the natural peptides that were hydrolyzed by BjV, the ability of the other venoms to hydrolyze

angiotensin I (65 μM) was analyzed using 4 μL of each selleck products one (B. alternatus [5.74 mg/mL], B. jararacussu [3.11 mg/mL], B. moojeni [0.86 mg/mL] and B. neuwiedi [0.11 mg/mL]). The scissile bonds found in angiotensin-I produced by these venoms were deduced by internal standardization of the HPLC system, using the results obtained with B. jararaca as reference. The ability of the antibothropic serum to neutralize the venoms proteolytic activities was estimated by incubating Rho it with Bothrops spp. venoms. Samples of Bothrops venoms were incubated, at room temperature, in the presence and absence of the antibothropic serum. The residual proteolytic activities of the venoms were measured as described above, using both FRETs substrates. The volume of the antibothropic serum and the pre-incubation time for serum neutralization of the proteolytic activities were established by using the B. jararaca venom. After establishing the best conditions to neutralize the metallo- and serine peptidases from the B. jararaca venom, the other Bothops spp venoms were tested (B. alternatus, B. jararacussu, B. moojeni and B. neuwiedi). The venoms were

used in volumes of 2.0 μL when the Abz-Metal was utilized as substrate and 0.2 μL for the kinetics with the Abz-Serine (see concentration on 2.5). For the maximum blocking effect of the proteolytic activity, the venoms were incubated with 10 μL of the antibothropic serum for 30 min at room temperature. After this period, 5 μM of each substrate was added and the residual activity was measured as described above. The experiments were made in triplicate. The same concentrations of Bothrops spp venoms described in the angiotensin-I degrading assays were utilized to determine the neutralizing potential of the commercial serum. Thus, after a pre-incubation time (venoms and antivenom), 65 μM of angiotensin I was added and after 1 h more samples were analyzed by HPLC reverse-phase.
