05) in both cities, which indicated that climatic conditions differed between the months with or without floods. During the flooded months, the morbidity of dysentery was higher than the non-flooded months, followed by more precipitation, higher temperature, higher relative humidity and more sunshine duration. Fig. 2 shows that the morbidity of dysentery declined from 2004 to 2009, and more cases occurred in spring and summer in these cities. Table 4 shows the results of Spearman’s correlation test conducted to determine

the lagged effects between the morbidity of dysentery and explanatory check details variables during the study period in each city. The results indicated that the floods were positively correlated to the monthly morbidity of dysentery with no month lagged among the three cities. The lagged values of climatic variables in these cities were the same except for the monthly average temperature

in Kaifeng according to the coefficients in Table 4. The parameters of the models and RRs of floods on the risk of dysentery are presented in Table 5. Results showed that floods were significantly associated with the morbidity of dysentery in each of the three cities (Coefficients: 2.44 in Kaifeng; 0.30 in Xinxiang; and 1.01 in Zhengzhou). However, flood duration was negatively correlated with the morbidity of dysentery (Coefficients: −0.63 in Kaifeng; −0.50 in Xinxiang learn more and −0.36 in Zhengzhou). During the flooded months, floods were significantly associated with an increased risk of dysentery with adjustment for meteorological factors in Kaifeng (RR = 11.47, 95% CI: 8.67–15.33). The RRs of dysentery for floods in Xinxiang and Zhengzhou were 1.35 (95% CI: 1.23–3.90) and 2.75 (1.36, 4.85), respectively. In addition, the overall effects of Oxalosuccinic acid floods on dysentery in the entire region were estimated through the overall function. As shown in Table 6, an increased risk of dysentery in this region was found, which indicated that floods could increase the

morbidity of dysentery in flooded months (RR = 1.66, 95% CI: 1.52–1.82). This overall model also indicated the extent of dysentery epidemics in the cities. Compared with Kaifeng city, the intensity of dysentery epidemic in Zhengzhou was the greatest with the highest morbidity in terms of the coefficients of the model (Coefficient: 1.13, 95% CI: 1.11–1.16), followed by Xinxiang with lower intensity and morbidity (Coefficient: 0.19, 95% CI: 0.15–0.22). Our study is the first time to demonstrate the quantitative risk of the relationship between the morbidity of dysentery and floods on the basis of a longitudinal data from 2004 to 2009. The results indicated that floods play an important role in the dysentery epidemics during the flood-month.

Importantly, CD5 was one of only two proteins identified with at

Importantly, CD5 was one of only two proteins identified with at least BMS-907351 molecular weight 2 peptides specifically in the VLR32-containing IP compared to the ‘minus-VLR32’ negative control.

The other identified protein, myosin-9 was only identified with 2 spectra from 2 unique peptides, corresponding to a sequence coverage of only 1%. Using this approach we determined that VLR32 immunoprecipitations contained the CD5 antigen (Table 2). We verified these results in parallel experiments testing the reactivity of VLR32 with cells transfected with CD5–GFP fusion constructs, by western blot analysis and immunoprecipitation experiments. VLR32, but not the negative control VLR4, was able to detect CD5–GFP fusion proteins in cell lysates from transiently transfected HEK293T cells (Fig. 3A). This Protein Tyrosine Kinase inhibitor reactivity was limited to lysates separated under non-reducing conditions as separation of cell lysates under reducing conditions abolished VLR32 binding (data not shown). In additional experiments, we demonstrated that VLR32 but not the negative control VLR4

precipitated CD5–GFP fusion proteins from cell lysates of transiently transfected HEK293T cells (Fig. 3B) and that VLR32 but not VLR4 stained HEK293T cells transfected with CD5 expression constructs in flow cytometry experiments (Fig. 3C). These experiments demonstrate the CD5-specificity of VLR32. Prior studies of VLR antibodies suggest that binding of the antibody to the antigen is avidity-based and that the affinity of

the individual antigen-binding unit to the antigen is often comparatively low (Herrin et al., 2008 and Kirchdoerfer et al., 2012). To investigate the affinity versus avidity-based binding of VLR32 to the CD5 antigen, we generated monomeric VLR32 antibodies by deleting the C-terminal 42 residues of the VLR antibody. As learn more expected, the resulting individual VLR units displayed a slightly faster migration pattern compared to full-length VLR proteins (Fig. 3B). Only the multimeric VLR32 was able to bind to CD5 efficiently as shown for immunoprecipitation (Fig. 3B) and flow cytometry analyses (Fig. 3D). VLR binding was not detected by flow cytometry using the monomeric VLR32 (Fig. 3D) and only a weak signal was obtained for immunoprecipitated CD5–GFP using the monomeric VLR32 (Fig. 3B). These data indicate an avidity-based contribution to the binding of the VLR32 lamprey antibody to human CD5. In this study, we demonstrate for the first time that monoclonal lamprey VLR antibodies can be used for purification and mass spectrometry-based identification of cell surface expressed protein antigens. Unlike conventional immunoglobulin-based antibodies, VLR antibodies utilize their leucine-rich repeats as basic structural units, resulting in a fundamentally different protein architecture of antigen receptors.

tackled this problem by integration of MS, NMR, and IM-MS data [74] to characterize αB-crystallin, a small heat shock protein

(Fig. 4). MS data indicated that this system exists in a dynamic equilibrium of differently sized oligomers. NMR spectra revealed that each monomer exists in a symmetrical environment. A range of candidate structures was constructed formed by either series of regular polyhedra or rings. Computed collision cross-sections (CCS) of these models were compared to those obtained experimentally. Enzalutamide datasheet Using the observed trends in CCS, consistent models of the dominant αB-crystallin 24-, 26- and 28-mer oligomers were identified as polyhedral architectures. These arrangements provide a structural rationale for the interconversion of these oligomers via loss and addition of a subunit. In a similar integrated approach atomic structures of 24-mer αB-crystallin complexes have been derived [75] and [76]. Lack of symmetry in a check details complex also means a significant loss of information to drive the modeling. Thus studies on non-symmetrical complexes are typically limited to dock two subunits together, of which one may be a known, multi-subunit complex itself. Recent work of the Kay lab

focused on the interaction between the 70 kDa DnaK and the 580 kDa hexameric ClpB in protein disaggregation [77]. Using an impressive, and pragmatic, combination of backbone and methyl-group based TROSY and complexes with hexameric and monomeric

variants of ClpB, the authors could define the binding surfaces on both proteins from CSP measurements and identify a 1:6 stoichiometry of the DnaK:ClpB complex. PRE measurements were performed on complexes of ILVM-labeled DnaK nucleotide binding domain bound to monomeric ClpB, labeled with MTSL at five different positions. The resulting 29 distance restraints were combined with CSP-derived Calpain ambiguous interaction restraints to dock the DnaK-NBD to a ClpB monomer (Fig. 5). The models were validated by mutagenesis and used to devise functional test of ClpB–DnaK function in protein disaggregation, revealing that the DnaK–ClpB interaction stimulates ClpB activity on the substrate. A nice example of how different types of NMR data can be used comes from the docking of a nuclear export signal (NES) peptide to the 150 kDa exportin CRM1/RanGTP complex [42] and [78]. Using an intricate combination of 13C-direct detection, CRINEPT-TROSY, several ambiguous and unambiguous intermolecular NOEs and solvent PREs, the peptide was docked precisely and in a well-defined conformation to its binding site. The resulting structures were consistent with the crystal structure of the complex based on a NES-fusion protein and explained structural basis of NES recognition. As a large DNA–protein complex, nucleosomes present an additional challenge in modeling of their complexes with other chromatin factors.

The recombinant protein was maintained at −80 °C and diluted in s

The recombinant protein was maintained at −80 °C and diluted in sterile phosphate buffered saline (PBS). Polyoma middle T oncogene-transformed mouse endothelioma cells derived from thymus (t-End) (Willians et al., 1988) were cultured in RPMI 1640 supplemented with Neratinib 10% fetal bovine serum (FBS) in a 5% CO2, humidified atmosphere, at 37 °C. Cells were used in the 3rd passage. t-End cells were used to carry out the in vivo and in vitro studies in mice, and the expression of PECAM-1 was determined before the beginning of assays, which provided data about the responsiveness of the cell strain to be employed.

The dorsal skinfold chamber was implanted in male Swiss mice under anesthesia, as previously described by Harder et al. (2004). Amblyomin-X (1, 10 or 100 ng/10 μl) or PBS was topically applied and in sequence VEGF-A (10 ng/10 μl) or PBS (10 μl) was also locally applied. This treatment schedule was carried out on the 3rd, 5th and 7th days after chamber implantation. Animals were immobilized in a polycarbonate tube and the microcirculatory network in the windows was digitized using intravital microscopy equipment (Carl Zeiss, Germany) and photographed using a digital camera (Sony–Cyber-Shot – 7.2 Mega Pixels/Optical

3X, Japan). The images obtained before (day 3) and after the treatments (day 9) were quantified according to Dellian et al. (1996). Results were expressed as percentage of vessels in comparison to the control VE-821 mouse group of animals (PBS-treated animals). Fertilized chicken eggs were incubated (65% humidity, 37 °C), and on 11th day of incubation, a sterile cellulose disc (2 mm) was placed on the CAM and Ringer solution (10 μl, control), Amblyomin-X (100 ng/10 μl) with or without VEGF-A (0.25 ng/10 μl) was subsequently applied topically. Treatments were daily

until the 14th day. The discs were removed and photographed with a digital camera coupled to a magnifying glass (Nikon, magnification 1×). Quantification of CAM vascular network was assessed by counting the number of vessels present on the disc area. Results were expressed as percentage of vessels in comparison to control membranes, treated with Ringer Exoribonuclease solution. All experiments were conducted with a FACS Canto Flow Cytometer (Becton Dickinson, Mountain View, CA, USA) and analyzed using the Flow Jo (version 9.1) software. Data from 10.000 cells were obtained and only the morphologically viable endothelial cells were considered in the analysis. t-End confluent cells were incubated with PBS or Amblyomin-X (100 ng/ml) in medium supplemented with 10 or 1% BSA. Afterwards at 72 h, cells were harvested and necrosis and apoptosis were measured by adding propidium iodide (PI) or annexin-V, respectively. Cell proliferation was measured in adherent t-End cells labeled with carboxyfluorescein diacetate succinimidyl ester (CFSE) according to the manufacturer’s instructions.

“Although mortality rates for seafaring have declined grea

“Although mortality rates for seafaring have declined greatly over the course of the 20th century, seafaring has continued to remain amongst the most hazardous of occupations. Merchant shipping is known to have a high rate of fatalities caused by occupational accidents and maritime disasters [1] and [2]. Human and organizational factors account for the vast majority of unanticipated significant problems associated with the design, construction, and operation of ships. For example, Moore et al. [3] found that most accidents result

from a compounding sequence of breakdowns in physical components, human error, and www.selleckchem.com/products/3-methyladenine.html organizational failures. Technology and automation are often introduced to increase efficiency and safety, reduce workload, reduce human involvement and the effect of human error. However, the human-automation interaction can have consequences for human work and safety as the automation can create new error pathways and delay opportunities for error detection and recovery [4]. The human role in the system is complex since a person’s individual characteristics and states, abilities and competencies affect decision-making and performance on board. The human in the system is both error inducing and an important source of expertise for decision-making and recovery [5]. While the human and system aspects are vital for safety, the organizational aspect also has a fundamental influence on safety [6]. Crizotinib clinical trial The capsizing of

this website the Herald of Free Enterprise just outside the Belgian port of Zeebrügge in 1987, with the loss of 193 lives, is one important example. It emphasizes the organizational aspect of having a poor safety culture on different levels in a shipping company [7]. Corporate safety cultures shaped by the degree of commitment to safety on the management level are often highlighted as the overriding factor for safety performance. Conflicting

safety and production goals, ineffective communication, time pressure, and fierce competition in a complex industry environment, can very likely lead to the stretching of safety margins (often unconsciously), and the migration of behavior towards the boundary of acceptable performance [8], also known as a “drift into failure”. A safety culture that stresses proactive measures for maintaining safety in an organization is a vital counterforce to the possible drift into failure. Thus, to maintain and improve safety and efficiency in safety critical maritime organizations, knowledge is needed about the safety culture and the way it is expressed in attitudes, behaviors, and artifacts. Questionnaires developed for this purpose are often used when assessing an organization’s safety culture. The analysis and interpretation of questionnaire results can provide more knowledge about the maritime safety culture concept and contribute to the formulation of effective interventions to maintain and improve safety and safety culture on board ships.

above) is by no means exhaustive and that for this particular case, the correct binding pose could not be identified. Most of these compounds bind to proteins with large binding pockets, such as hERG, LXR, PPARγ and CYP3A4. On the other hand, compounds predicted too strongly ( Fig. 4: points above the diagonal) might trigger an induced fit that has been simulated but could not be appropriately quantified. Other factors of uncertainty include entropic effects and the quantification ERK inhibitor mouse of protein-bound solvent released upon ligand binding. A final source of inaccuracy

may stem from the sampling of a compound’s representations in aqueous solution (software Aquarius). While currently the 25 energetically most favorable conformations (obtained from conformational sampling employing an implicit solvent model; software MacroModel), are optimized in explicit solvent, they may not include all relevant representations. We modified the protocol to include 100 conformers (requiring approximately 2–4 extra CPU hours per compound) but, unfortunately,

with only minimal benefit. The philosophy underlying selleck products the VirtualToxLab is to estimate the toxic potential of a compound through the normalized individual binding affinities towards a series of protein models known or suspected to trigger adverse effects. The result is a value ranging from 0.0 (none) to 1.0 (extreme), which may be interpreted as a toxicity alert. In a first step, the individual binding affinities are normalized for each individual target protein according to Eq. (1). equation(1) affinity>1.0×10−2M→affinitynorm=0.01.0×10−2M≥1.0×10−10M→affinitynorm=[log⁡(1.0×10−2)−log⁡(affinity)][log⁡(1.0×10−10)−log⁡(1.0×10−2)]affinity<1.0×10−10M→affinitynorm=1.0}Next, the individual toxic potential, TPindividual, is calculated, again for each individual target protein (Eq.

(2)): equation(2) TPindividual=affinitynormalized×weightstandarddeviationTPindividual=affinitynormalized×weightstandarddeviationwith Epothilone B (EPO906, Patupilone) weightstandarddeviation = 1.0–0.125 × (standard deviation/affinity); standard deviation over the 12 (24) models and therein: 0.125 = 1/ΔpKmin,max (ΔpKmin,max = 8.0: affinity range from 1.0 × 10−2 M to 1.0 × 10−10 M). Therefrom, the overall toxic potential (TPoverall) is determined as follows: first, the 16 TPindividual are ranked by their value. Then, their contribution to the TPoverall is summed up according to Eq. (3). equation(3) TPoverall=∑n=116(1.0−TPoverall,current)×TPindividual,n×Wsuperfamilywith wsuper family = 1.0/n (n: nth member of a super family). To avoid substantial TPs resulting from high affinities to evolutionary similar protein targets (e.g., ERα and ERβ), a correcting weight, wsuperfamily, is applied. It decreases the contribution for the nth member to the TP.

The potential applications of this technique in the food industry

The potential applications of this technique in the food industry are very wide and include blanching, evaporation, dehydration, fermentation and pasteurization (FDA., 2000 and Sarang et al., 2008). l-ascorbic acid (AA) is one of the most important natural antioxidants supplied by fruits and vegetables; it is the main biologically active form of vitamin C. This vitamin, present in high levels in the acerola pulp, is used as a quality index because it is very sensitive to degradation during processing

and storage ( Lee & Kader, 2000). The degradation of vitamin C occurs under both aerobic and anaerobic conditions. The first case is characterized by the reversible oxidation of AA to l-dehydroascorbic acid (DHA), selleck inhibitor which also exhibits biological

activity. Further irreversible oxidation of DHA generates diketogulonic acid (DCG), which has no biological function. The degradation of vitamin C under anaerobic condition is not yet elucidated due to its complexity ( Fennema, 1996). Vitamin C is most sensitive AZD8055 datasheet to destruction when the product is subjected to adverse handling and storage conditions. Losses are increased by extended storage, high temperatures, low relative humidity, physical damage, and chilling injury ( Lee & Kader, 2000). The objective of this study is to evaluate the degradation of vitamin C in acerola pulp after thermal processing by both ohmic and conventional heating. The ohmic heating technology was studied using a Central Composite Rotatable Design in which the variables evaluated were the total solids content of the pulp (2–8 g/100 g) and the heating voltage (120–200 V; electric field strength 21–36 V cm−1). Acerola Selleck Osimertinib pulp, supplied by Mais Fruta Company, was received frozen in packs of 100 g and was stored at −18 °C for later analyses. The samples were diluted by adding deionized water to adjust the total solids content to five different amounts (ranging from 2.0 to 8.0 g/100 g) and then homogenized using a magnetic stirrer

(Instrulab, Model ARE, Brazil). The experimental setup comprises a power supply, a variable transformer (Sociedade Técnica Paulista LTDA, model Varivolt, Brazil), a stabilizer (Forceline, model EV 1000 T/2-2, Brazil), a data acquisition system, a computer and an ohmic cell. The experimental apparatus is schematically shown in Fig. 1. The voltage across and the current through the ohmically heated sample were measured using voltage and current transducers. The temperature was monitored by two temperature sensors (Novus, model pt-100, Brazil). These variables were recorded at constant time intervals by a data logger (Novus, model Field logger, Brazil) linked to a computer. The ohmic cell was made of a 400 mL Pyrex glass vessel and was equipped with a water jacket. The lid of the vessel contained four ports for temperature sensors and two ports for the electrodes. The electrodes were made of platinum with cross-sectional areas of 7.0 cm2.

Furthermore, the 8-day (August 23–30 2008) composite of MODIS/Aqu

Furthermore, the 8-day (August 23–30 2008) composite of MODIS/Aqua derived SST over the affected area was 0.5–1 °C lower than adjacent offshore waters (Fig. 5b). Therefore, it can be hypothesized that the bloom was initiated offshore and transported nearshore by bottom Ekman layer. This is similar to the observations made on the West Florida Shelf, where Weisberg et al. (2009) showed that the pathway of bloom to the nearshore was primarily via the bottom Ekman layer by an upwelling circulation. Fig. 6 shows an example of the existence of upwelling during the bloom period. The cold-core eddy was characterized by anticlockwise spinning and relatively STAT inhibitor low SSH (Fig. 6a) and induced upwelling. MODIS derived

SST on the same day (Fig. 6b) confirmed the occurrence of eddy-induced upwelling. Two patches of low temperature can be recognized north of UAE in the Strait of Hormuz and south of Iran in the Gulf of Oman, respectively. The anomalously low SST indicates that cold, nutrient-rich bottom waters was moved upward and subsequently provided nutrient supplies for phytoplankton growth. Cold-core eddies can also be identified in Fig. 4, e.g. south of Iran in the Arabian Gulf and in the eastern Gulf of Oman on September 24 2008. A La Niña episode occurred from late 2008 to early 2009. La Niña conditions have the effect of intensifying

upwelling, which brings the pycnocline and nutricline up closer to the sea surface, more easily entrained

into the upper euphotic zone (Linacre et al., 2010). AOT is an estimate of FK866 manufacturer the particle loads in the air column, and has been used as an indicator of atmospheric turbidity (Volpe et al., 2009 and Gallisai et al., 2012). Although high loads of atmospheric dust does not necessarily mean high deposition, strong positive correlations have been found between AOT and chlorophyll-a by Volpe et al. (2009). Additionally, these high dust levels affect significantly the chlorophyll-a estimates by increasing AOT estimates from satellite resulting in artificially high chlorophyll-a concentrations. Region-specific atmospheric correction algorithms calibrated and validated in the dusty environment NADPH-cytochrome-c2 reductase of the Arabian Gulf would help to improve the accuracy of satellite-derived estimates. The contribution of dust-induced nutrients to the enhancement of marine productivity in the Arabian Gulf has been proposed by Hamza et al. (2011). Furthermore, Nezlin et al. (2010) showed that the atmospheric deposition is an important factor regulating phytoplankton growth in the Arabian Gulf. Fig. 7 presents the monthly anomaly of MODIS/Aqua derived AOT at 869 nm for February 2009. Positive anomalies were found in the middle and eastern Arabian Gulf, along the east coast of UAE, and in the northeastern Gulf of Oman. Hence, dust deposition may have served as an important source of nutrient supply.

Neuroticism is a complex construct that includes several differen

Neuroticism is a complex construct that includes several different traits and facets (see Eysenck & Eysenck, 1985), including thinking styles such as being “irrational”, and denotes an increased general tendency towards negative emotional reactivity and arousal. There is evidence that the relation between neuroticism and depressive symptoms is mediated by ruminative tendencies and increased cognitive reactivity, which

is defined as the tendency for negative thinking to become triggered through only subtle changes in mood (Barnhofer and Chittka, 2010 and Roelofs et al., 2008). Ruminative tendencies Selleckchem EPZ015666 and cognitive reactivity both play an important role in the recurrence and maintenance of depressive symptoms and are therefore important targets for preventative interventions (Nolen-Hoeksema et al., 2008 and Scher et al., 2005). Recently interest has increased

in the use of training in mindfulness meditation as a way of addressing these factors. Mindfulness has been described as the ability to maintain awareness moment by moment in an open and acceptant way (Kabat-Zinn, 2003). Importantly for clinical care, training in mindfulness can help individuals become better able to identify and disengage from maladaptive patterns of responding and thus prevent downward spirals of negative mood and thinking (e.g. Segal, Williams, & Teasdale, 2002). Other research Sirolimus clinical trial on mindfulness-based interventions lends further support: In those who are at

risk for depression, intensive Liothyronine Sodium training in mindfulness reduces ruminative tendencies (Ramel, Goldin, Carmona, & McQuaid, 2004) and the negative effects of cognitive reactivity (Kuyken et al., 2010). Rumination and cognitive reactivity are processes that are high in people who are high in neuroticism, so if mindfulness can reduce these processes, it seems plausible that mindfulness is a skill that can help to prevent neuroticism from translating into depressive symptoms. Thus, delineating such effects would be helpful in understanding how the negative emotional outcomes of neuroticism can be prevented. This would be important for the prevention of depression, as well as the broad range of emotional disorders given that neuroticism accounts for a significant amount of common variance across the mood and anxiety disorders (Griffith et al., 2010). Mindfulness-based interventions are now increasingly being adapted for the whole spectrum of these disorders (Hofmann, Sawyer, Witt, & Oh, 2010) and demonstrating the effects on global vulnerability factors would be an important step in justifying such broadening of application.

Microinjection of aCSF into the contralateral PVN (n = 6) did not affect either MAP (101 ± 3 vs. 98 ± 2 mm Hg, t = 0.5, P > 0.05) or HR (353 ± 11 vs. 361 ± 7 bpm, t = 0.5, P > 0.05) baseline values. Contralateral PVN treatment with aCSF also did not affect the pressor (43 ± 4 vs. 39 ± 3 mm Hg, t = 0.8, P > 0.05) and bradycardiac (− 76 ± 9 vs. − 68 ± 6 bpm, t = 0.8, P > 0.05) response to carbachol microinjection into the BST ( Fig. 6A).

values. Moreover, contralateral PVN pretreatment with CoCl2 did not affect the pressor (42 ± 4 vs. 41 ± 2 mm Hg, t = 0.1, P > 0.05) and bradycardiac (− 70 ± 9 vs. − 65 ± 8 bpm, t = 0.5, P > 0.05) response to carbachol microinjection into the BST ( Fig. 6A). Time-course analysis did not show a significant effect of contralateral PVN pretreatment with CoCl2 in carbachol cardiovascular responses (ΔMAP: F(1,380) = 2, P > 0.05; ΔHR: F(1,380) = 0.2, P > 0.05) ( Fig. 6B), but indicated a significant Wnt inhibitor effect over time on the MAP (F(37,380) = 44, P < 0.0001) and HR (F(37,380) = 11, P < 0.0001). Photomicrography of coronal brain section showing the microinjection site in the ipsilateral and contralateral PVN of representative animals is presented in Fig. 7 and Fig. 8, respectively. Diagrammatic representation showing microinjection sites of CoCl2

and aCSF in the ipsilateral and contralateral PVN is also shown in Fig. 7 and Fig. 8, respectively. The BST is localized in the rostral prosencephalon, and is associated with autonomic and neuroendocrine functions (Dunn, Celecoxib 1987, Dunn and Williams, 1995 and Ulrich-Lai and Herman, 2009). Cholinergic synaptic terminals were indentified in the BST (Ruggiero et al., 1990). Moreover, binding studies described the presence of muscarinic and nicotinic receptors in the BST (Clarke et al., 1985 and Wamsley et al., 1984). Electrophysiological studies reported that BST neurons showed an increase in firing rate in response to local administration of acetylcholine through activation of local muscarinic cholinergic receptors (Casada and Dafny, 1993a and Casada and Dafny, 1993b). We have previously reported that microinjection of carbachol, a cholinergic agonist, into the BST of unanesthetized rats evoked a pressor response that was followed by a baroreflex-mediated bradycardia (Alves et al., 2007). These cardiovascular effects were blocked after local pretreatment with an M2-muscarinic receptor antagonist as well as after systemic pretreatment with a V1-vasopressinergic receptor antagonist (Alves et al.
