, 1996, Majchrowski, 2001 and Woźniak and Dera, 2007). The relationship between the number of quanta and the energy of the light absorbed by phytoplankton pigments is given by the so-called quantum equivalent of light energy X, which is equal to the ratio of the number of quanta absorbed to the sum of their energies. By taking this equivalent X into account, we can calculate the energy efficiencies of fluorescence Rfl and Fulvestrant rfl on the basis of the corresponding quantum yields of this process Φfl and qfl, using the equations given in Table 1 (lines 1, 2). For these calculations, we take the value of X that we calculated for the

light absorbed by all phytoplankton pigments 1. using the equations from the earlier comprehensive light-photosynthesis model ( Woźniak et al. 2003). The vertical distributions of X in sea waters of different trophic types and at different depths

in the upper water layers, of thicknesses from 1 to 2 times the depth of the euphotic zone, are given in Figure 2. From the characteristics of the variability of X it becomes clear that the energy efficiencies of chlorophyll Rapamycin a fluorescence (Rfl and rfl) are usually somewhat lower than the quantum yields of this process (Φfl and qfl), especially in oligotrophic, mesotrophic and weakly eutrophic basins. Again, the energy efficiencies of photosynthesis (Rph and rph) are usually some four times smaller than the corresponding quantum yields of the process (Φph and qph). This is because a minimum of eight quanta from all the light quanta absorbed by PSP molecules (together with the chlorophyll a molecules at the photosynthetic reaction centres) are required to close off the cycle of endoenergetic chemical

reactions in photosynthesis leading to the assimilation of one atom of carbon, even though not Mannose-binding protein-associated serine protease all of the energy of these eight quanta is utilized in these reactions ( Govindjee, 1975 and Najafpour, 2012). The energy equivalent of organic carbon kep contained in various organic substances may fluctuate within quite wide limits, depending on the type of substance involved. For substances photosynthesized by phytoplankton this equivalent kep ≈ 40 kJ g− 1 ( Koblentz Mischke et al. 1985). This calculation shows that for one atom of carbon to be assimilated, that is, for it to be bound in an organic form, the energy contained in two quanta of light from the visible spectrum is more than sufficient. The resulting relationships between the energy efficiencies (Rph and rph) and quantum yields (Φph and qph) of the photosynthesis of phytoplankton in the sea are given in Table 1, lines 2 and 4. Likewise, the efficiencies of the conversion of pigment molecule excitation energy into heat (in the radiationless and nonphotochemical dissipation of this energy) RH and rH differ from the quantum yields of these processes ΦH and qH.

Furthermore, an intensification of the oceanic heat transport at

Furthermore, an intensification of the oceanic heat transport at 45°N is consistent with a capture of heat from the atmosphere into the ocean between 30°N and 45°N, as seen along the North Atlantic Current path (Fig. 11 bottom colours). Fig. 12 shows the annual mean transport of freshwater (in mSv, using 34.8 psu as a reference) across the same selected sections. This figure can be compared to estimates by Talley et al., 2003) (the net volume transports were removed prior to computing the freshwater transports).

The sign of these transports generally agrees with the observations: The ACC transports freshwater eastward, which enters at the southern edge of each oceanic basin. In the North Atlantic and North Pacific, on the other hand,

the net transport is southward, and convergences occur in the subtropics, where evaporation selleck screening library (colours) is maximum. Comparing CM5_piStart and CM5_RETRO, we notice generally Linsitinib cost a qualitative compensation in terms of density between the anomalous heat and freshwater transports, in particular in the Atlantic and the Indian oceans and zonally in the Southern Ocean. In the tropics, anomalies of the total atmospheric freshwater fluxes out of the ocean are generally strong, except in the Pacific, and consistent with a northward shift of the ITCZ in CM5_piStart in the Atlantic and the Indian Ocean, as described above. In the Pacific, anomalous freshwater fluxes are rather indicative of a stronger SPCZ (or double ITCZ) (not shown). All these changes in the atmospheric flux induce associated salinity anomalies in surface as described earlier (Fig. 4). Finally, as indicated above, strong changes are also found in the northern Indian basin, where colder conditions in CM5_piStart induce less evaporation Adenosine and weakened northward freshwater. Fig. 13 shows the total net mass transport across the same selected sections as for the heat and freshwater

transport in CM5_piStart (top) and in terms of differences between CM5_piStart and CM5_RETRO (bottom). The net mass transport is generally stronger in CM5_piStart than in CM5_RETRO. At the Drake Passage, in particular, the total transport amounts about 109 Sv in CM5_piStart, which is 23% more than in CM5_RETRO, but still weaker than the value inferred from observations (136.7 ± 7.8 Sv Cunningham et al., 2003). Such an intensification of the ACC from AR4 to AR5 configuration is very close to the 21% increase diagnosed in the forced configurations described above. This suggests an important role of the changes in the oceanic component in this evolution (rather than changes in the atmosphere, impacting wind stress for instance). The weak ACC intensity was a known deficiency of the IPSL-CM4 climate model (e.g. Marti et al., 2010; Marini et al., 2010). The latter is enhanced from 50 Sv in CM4_piCtrl (references above) to 98 Sv in CM5_piCtrl (Fig. 1), thus an increase of roughly 50%, which is twice as much as what is found from CM5_RETRO to CM5_piStart (Fig.

Table 1 summarizes our results The vast majority of the tumors e

Table 1 summarizes our results. The vast majority of the tumors expressed SCF ( Figure 1B and Supplemental Figure 1B and F); it was largely found in the duct-type epithelial component ( Figure 1C) where c-Kit was predominantly elevated ( Figure 1B). We used antibody-based IHC to detect active forms of ERK1/2 on tumor sections (Figure 1E). The Ras-Raf-MEK1/2-ERK1/2 cascade is a major downstream effector-signaling pathway of RTKs, including c-Kit. Thus, SCF-induced Trichostatin A cost activation of c-Kit would accompany

active ERK1/2 expression in the inner duct-type epithelial component of the tumor cells where c-Kit was elevated. Table summarizes our results. In 17 of 27 ACCs, active ERK1/2 protein was substantially increased in more than 20% of tumor cells. Interestingly, other types of non-cancerous cells adjacent to tumors

within salivary glands were positive for SCF. They included stromal fibroblasts (Figure 2A and Supplemental Figure 2A and B), neutrophils ( Figure 2B and Supplemental Figure 2C and D), peripheral nerve ( Figure 2, C–E and Supplemental Figure 2E), skeletal muscle ( Figure 2F and Supplemental Figure 2F), vascular endothelial cells ( Figure 2G), and mucous acinar cells and intercalated ducts selleck chemical ( Figure 2H). Strong immunoreactivity to the SCF antibody was found in neutrophils and peripheral nerve ( Figure 2, B and D). In addition, Figure 2E shows that staining for SCF highlights a peripheral nerve with a tumor wrapping around the nerve bundle,

creating a targetoid pattern. We investigated whether mRNA expression of c-Kit and SCF was also elevated in ACC (Figure 3, A and B), and also included EGFR because it has been implicated in the development of ACC ( [17] and [18]; Figure 3C). mRNA was isolated from FFPE sections as described above, and quantitative PCR performed. Figure 3A shows that c-Kit mRNA expression was elevated Roflumilast in ACC, with the relative expression increased by 1.88 (P < .05) over the average of normal samples. The top quartile of mRNA expression of c-Kit particularly distinguished ACCs from normal salivary tissues. In contrast, the expression levels of SCF and EGFR mRNA showed a broad range, which overlapped with those in normal tissue ( Figure 3, B and C) and showed no significant difference (P > .05) from ACC samples. Given that SCF-mediated c-Kit activity is important for local invasion and metastasis, we determined the strength of correlation between SCF and c-Kit mRNA expression in the presence (cases 1, 11, 15, 16, 21, 23, 25 and 26; Table) or absence of perineural invasion (PNI). We generated scatter plots with trend lines to show correlations (Figure 4, A–C). Trend line equations and R-squared values were calculated with Microsoft Excel and are displayed atop each chart.

However, optical tracking techniques are limited to transparent systems and suffer a low resolution due to refraction of light. A significant amount of food is processed after packing into cans or pouches, and the solid and liquid motions cannot be tracked through optical technique. A number of models have been developed for

such systems, such as Chen and Ramaswamy, 2002, García María-Sonia et al., 2006, Miri et al., 2008, find more Abdul Ghani and Farid, 2006, Jun and Sastry, 2007 and Kannan and Sandaka, 2008. Positron Emission Particle Tracking (PEPT) was developed at the University of Birmingham for tracking a single particle accurately and non-invasively (Bakalis et al., 2006, Cox et al., 2003, Parker et al., 1993 and Yang et al., 2008a). The significant advantage of the method is that PEPT can track particles accurately through 20–30 mm of metal. The equipment used thus need not be transparent as with particle imagery velocimetry (PIV) (Duursma, Glass, Rix, & Yorquez-Ramirez, 2001) or be metal free as with magnetic resonance imaging (MRI) experiments (Reyes, Lafi, & Saloner, 1998). The technique has been recently further improved to track three particles simultaneously (Yang, Parker, Fryer, Bakalis, &

Fan, 2006). This makes it possible to track both translational and rotational motions of a particle simultaneously. Yang, Fan, Bakalis, Parker, and Fryer (2008b) presented the algorithm, and have demonstrated the use of the method for one simple case. In this study the solids behaviours CHIR99021 in a rotating can system are investigated systematically using our newly developed technique called Multiple-PEPT. The translational motion gives the solids velocity profile, whilst from the rotational motion the distribution of rotational speed is constructed. The aim of the work is to demonstrate

the method and to give data which can be incorporated into future models of food flows. Experimental methods consist of Multiple-PEPT and reconstruction Avelestat (AZD9668) of the translational and rotational motions by three tracked tracers, described as follows. The technique involves a positron camera at the University of Birmingham, radioactively labelled tracers (Fan et al., 2006a and Fan et al., 2006b), and a location algorithm used for calculating the tracer location and speed. The camera consists of two position-sensitive detectors to detect pairs of 511 keV γ-rays as shown in Fig. 1. Each detector has an active area of 500 × 400 mm2. The tracer particles are 200-micron resin beads which are labelled with radionuclide 18F. Three of the labelled resins beads were mounted to different corners of a potato cube. 18F has a short half-life of 109 min. It will decay to oxygen next morning. The nuclear dose used in the experiments is much less than the dose used in hospital for tumour diagnosis.

Most importantly, we detected all expected ratio and congruency e

Most importantly, we detected all expected ratio and congruency effects in the symbolic and non-symbolic magnitude discrimination tasks and detected other group × measure interactions at good significance levels. Second, in order to achieve high intra-individual power our study deliberately had a large number of trials in each experiment. There were 40 trials for each level of symbolic numerical distance in the symbolic discrimination task

(80 stimuli all together) and 40 trials for each level of ratio in the non-symbolic discrimination task selleck chemical (120 stimuli all together). That is, across the study we collected 12 × 40 = 480 trials for each ratio level in the DD group. In comparison to studies with positive MR results our study had 1.66–4 times as many Ku0059436 trials per ratio level than other studies: Price et al. (2007) presented 12 trials per ratio level (24 stimuli, eight DD children,

i.e., 96 trials for each ratio across the whole study), Mazzocco et al. (2011) used 20 trials per ratio level (80 stimuli, 10 DD children, i.e., 200 trials per ratio level across the whole study), Mussolin et al., 2010a and Mussolin et al., 2010b used 24 trials per ratio level (96 stimuli for each presentation format, 15 DD children, 360 trials per ratio level for each presentation format across the whole study), Piazza et al. (2010) used 10 trials per ratio level (80 stimuli, 23 DD children including 12 dyslexic children, i.e., 230 trials per ratio level across the study). In addition our study had 12 DD children which is more than oxyclozanide the number

of DD children in two out of the above four studies. Even when factoring in the larger number of DD children in the two remaining studies (Mussolin et al., 2010a, Mussolin et al., 2010b and Piazza et al., 2010) our study collected 1.33–2.08 times more trials per ratio level for each presentation format than other studies. This is advantageous because the larger number of trials effectively suppresses the amount of noise inherent to the data which increases power. Third, the impaired MR theory predicts that ratio effects in non-symbolic number discrimination will differ in DD relative to controls (Piazza et al., 2010, Mazzocco et al., 2011 and Price et al., 2007). In our study the between group difference in the mean ratio effect was .1%. In a similar non-symbolic number discrimination task Price et al. (2007) observed a 2.5% difference between groups in the ratio effect with the DD group showing a larger effect than controls because DD children were less accurate than controls at close ratios (close vs far ratio difference in controls: 3.87%, DD: 6.37%; accuracy for close vs far ratios in controls: 95.75% vs. 99.62%. In DD: 92.75% vs. 99.12%). In that study the standard deviation of the error data was about 1.65% and the group difference in the ratio effect was about 1.51SD. For the 12 subjects in our study this gives a Power estimate of Power > .99.

The other end was coupled to an isomeric transducer F-60 connecte

The other end was coupled to an isomeric transducer F-60 connected to a polygraph, both from NARCO BioSystems. The preparation was stabilized for 30 min, ventilated with carbogen (5% CO2 and 95 O2) and changing solution each 10 min. After stabilized, bradykinin at concentrations

16 × 103 to 4 × 103 μM was applied into the system, and the effects registered for 1 min. After that, the preparation was rinsed with Tyrode solution for five times. The bradykinin potentiating activity of kappa-KTx2.5 was evaluated by adding the synthetic peptide at concentrations of 3.19, 6.38 or 9.58 μM to the bath 3 min before the application signaling pathway of 4 × 103 μM bradykinin to the bath. The experiment was done in triplicate. The experimental protocol was approved by the University of Brasilia Animal Care and Use Committee (number 46594/2009). The activity of kappa-KTx2.5 toward Gram-positive Navitoclax (Staphylococcus aureus ATCC 29213) and Gram-negative (Escherichia coli ATCC 25922) bacteria was tested by the broth microdilution assay. The bacteria were grown in Luria-Bertani (LB) medium to the optical density of 0.5 at 600 nm. The highest concentration of the peptide used was 256 μM. Positive and negative controls were carried out with the inoculums plus LB medium and medium only, respectively. The spectrophotometric reading (630 nm) was performed after 12 h incubation time at

37 °C. The docking of the κ-KTx2.5 to the Kv1.2 was performed by AutoDock Suplatast tosilate 4 (http://autodock.scripps.edu/). The κ-KTx2.5 was modeled by Modeller9v6, using the template PDB ID: 1WQD [31]. The Kv1.2 potassium channel coordinates were obtained from its crystal structure PDB ID: 2A79 in its open conformation, and for the docking only the S5 and S6 helices were selected. The interacting portion channel-peptide of Kv1.1, 1.2 and 1.4 are similar. The Kv1.2 channel has a crystal structure, which explains our choice to modeling with the Kv1.2

channel, despite the biological assays done in different in Kv1.1 and 1.4. Both molecules were submitted to atomic charges calculation according to Gasteiger method [10]. The affinity grid maps were built with X-126, Y-126 and Z-126 dimensions, spacing by 0.6 Å. The channel was remained rigid while the peptide flexible, so the docking was carried out through the Lamarkian Genetic Algorithm [20]. For each run were used 15 million evaluations, and the other parameters in default. The results were analyzed with Pymol (http://www.pymol.org/) and the contact maps by the server Sting (http://www.nbi.cnptia.embrapa.br). The fractionation of the crude soluble venom of O. cayaporum by RP-HPLC yielded more than 80 fractions [30]. The component that eluted at 25.9% acetonitrile/0.1% TFA was further purified by analytical RP-HPLC as shown in Fig. 1. The component eluting at retention time of 12.58 min (see inset Fig. 1) was found to be the pure peptide here named κ-KTx 2.

Survival curves based on Cox proportional hazard regression model

Survival curves based on Cox proportional hazard regression models

are shown for systolic BP in Figure 2 and diastolic BP in eFigure 1. In initial age- and sex-adjusted analysis of the total sample (model 1), compared with systolic BP ≤ 125 mm Hg, mortality risk decreased with increasing BP category (126–139 mm Hg: HR 0.70, 95% confidence interval [CI] 0.53–0.93; 140–149 mm Hg: HR 0.63, 95% CI 0.48–0.83; 150–164 mm Hg: HR 0.59, 95% CI 0.45–0.76; ≥165 mm Hg: HR 0.50, 95% CI 0.38–0.66; Table 3, Figure 2A). find more None of these associations was significant in the fully adjusted model for the total sample (model 2). For diastolic BP, mortality risk was significantly increased in the quartile of BP lower than 70 mm Hg in model 1 (HR 1.42, 95% CI 1.11–1.81) and in the quartile of 70 to 74 mm Hg in models 1 (HR 1.32, 95% CI 1.03–1.69) and 2 (HR 1.37, 95% CI 1.03–1.83), compared with the quartile of 75 to 80 mm Hg (eTable 1, eFigure 1A). The association of BP with mortality differed among gait speed subcohorts. In the slower-walking subcohort, patterns of association were similar to those

of the total sample (Table 3, Figure 2B, eTable 1, eFigure 1B). In age- and sex-adjusted analysis of the faster-walking subcohort, mortality risk was more than twice higher in participants with systolic BP of 125 mm Hg or lower than in those with systolic BP of 126 to 139 mm Hg (HR 2.38, 95% CI 1.05–5.41). This association did not reach statistical significance in the fully adjusted 17-DMAG (Alvespimycin) HCl analysis (model 2); instead, mortality risk check details was more than twice higher in participants with systolic BP of 165 mm Hg or higher (HR 2.13, 95% CI 1.01–4.49) and 140 to 149 mm Hg (HR 2.25, 95% CI 1.03–4.94) than in those with systolic BP of 126 to 139 mm

Hg (Table 3, Figure 2C). For diastolic BP, mortality was significantly higher in the highest quartile (>80 mm Hg) in models 1 (HR 1.65, 95% CI 1.01–2.69) and 2 (HR 1.76, 95% CI 1.07–2.90) compared with the quartile of 75 to 80 mm Hg in the faster-walking subcohort (eTable 1, eFigure 1C). In the age- and sex-adjusted analysis, interaction effects between gait speed subcohort and BP in the association with mortality were significant for systolic BP (P = .031), but not for diastolic BP (P = .283). Interaction effects were not significant for systolic BP (P = .327) or diastolic BP (P = .272) in the fully adjusted model. Repeated analyses with the exclusion of data from participants who died in the first year of study inclusion produced essentially the same results (data not shown). In this study of a representative sample of very old individuals, low systolic and diastolic BP were significantly associated with increased mortality risk in initial age- and sex-adjusted analyses, but not in analyses adjusted for all covariates, including previous disease.

A pre-planned interim analysis was undertaken on 17 September 200

A pre-planned interim analysis was undertaken on 17 September 2008. This analysis was to assess whether to stop or evaluate the study if efficacy in the BE arm was worse than the BC arm. If the HR was greater than 1.25, indicating BC treatment was better than BE, the study would be re-evaluated. An updated analysis was performed on 6 January 2009 in order to increase the follow-up period of the randomized patients. The final analysis was on 9 September 2011. From

31 December 2007 to 17 September 2008, 124 patients were randomized (BE, n = 63; BC, n = 61; Fig. 1); 14 patients were withdrawn from trial treatment for safety reasons (8 BC and 6 BE). After results of the updated interim selleck inhibitor analysis were communicated, 10 patients were withdrawn due to administrative reasons in the BE arm (5 patients switched to commercially available erlotinib, 2 patients were withdrawn due to investigator decision and 3 patients were withdrawn due to study end). In the BC arm 4 patients switched to commercially available erlotinib. At Pexidartinib purchase the pre-planned interim analysis (data cut-off 17 September 2008) there were no post-baseline PFS assessments for 20 BE patients and 18 BC patients due to

<6 weeks between randomization and data cut-off. A further 12 patients in each arm were censored after randomization but before week 6. The HR for PFS for BE relative to BC treatment was above the predefined threshold of 1.25 (HR 2.17, 95% CI: 0.88–5.34). To account for the patients with no PFS events or insufficient time between randomization and cut-off to be accurately assessed, an updated interim analysis (data cut-off 6 January 2009) was performed. Recruitment was kept on hold but enrolled patients continued treatment. The HR for PFS at Resminostat the updated interim analysis was above the pre-defined value of 1.25 (HR 2.05, 95% CI: 1.11–3.77; p = 0.0183). Therefore recruitment was stopped permanently. Baseline demographics and patient characteristics for the intent-to-treat population are shown in Table 1. Both arms

had a higher proportion of males than females, and more patients with ECOG PS 1 compared with PS 0. Most patients had adenocarcinoma histology and most had stage IV disease. By the final analysis (9 September 2011) all patients had been withdrawn from trial treatment, therefore final analysis data are not available for some endpoints. All presented results are from the updated interim analysis (6 January 2009) unless otherwise stated. At the updated analysis, the risk of disease progression or death was significantly higher with BE compared with BC (HR 2.05, 95% CI: 1.11–3.77; log rank p = 0.0183). A total of 30 events in the BE arm (47.6%) and 16 events in the BC arm (26.2%) were observed. Median PFS was 18.4 weeks (95% CI: 17.0–25.1) with BE and 25.0 weeks (95% CI: 20.6–[not reached]) with BC. The p value of 0.0183 indicated a significant difference in PFS in favor of BC ( Fig. 2).

Other studies were conducted by scientists supported by Exxon (subsequently Exxon Mobil). These

different groups of scientists often collected different types of data and interpreted data somewhat differently; these Gefitinib manufacturer varied approaches, which often yielded disparate findings, enhanced scientific rigor, even if it led to less-certain conclusions. This paper was motivated by a series of recent reports asserting, definitively, that sea otters in one area of WPWS that was heavily oiled continue to suffer, individually and demographically, from residual effects of the 1989 spill (Bodkin et al., 2011, Bodkin et al., 2012, Monson et al., 2011 and Miles et al., 2012). Here we critically evaluate these and other previous studies that collectively have argued that selleck chemical effects of the spill persisted for more than two decades, thus providing the basis for keeping sea otters on the short list of species that

have not yet recovered from EVOS (Exxon Valdez Oil Spill Trustee Council, 2009). Our intent is not to present a comprehensive review of the impacts of the spill on sea otters, but rather to focus on results that have been interpreted as evidence of effects continuing to the present. We do not discredit any of the investigators who reached these conclusions; we simply aim to offer an alternate interpretation of data related to long-term demographic consequences. Acute effects of the spill on sea otters were well documented, and the vulnerability of this species to oil contamination confirmed (Bayha and Kormendy, 1990 and Lipscomb et al., 1994). Whereas estimates of direct, spill-related mortality varied widely with varying methodological procedures and assumptions (Garrott et al., 1993, DeGange et al., 1994, Garshelis, 1997 and Garshelis and Estes, 1997), there was no doubt that a large proportion of otters in WPWS

died. With time, and the continued weathering of the oil residues, it was generally presumed that sea otters would gradually rebound to baseline conditions. In an introductory chapter to a book summarizing a symposium on effects of EVOS, held 4 years Thiamine-diphosphate kinase after the spill, Spies et al. (1996, p. 11) wrote: “These results do not preclude ongoing toxic effects in highly sensitive species in some areas, but they do support a conclusion that direct effects of the oil in the intertidal zone [where the residual oil settled] were largely over by 1991, when major cleanup activities ceased.” Indications that this was not the case for sea otters began to emerge by the mid-1990s, stimulating further studies of recovery of this species (Holland-Bartels et al., 1996).

Despite the good agreement between nTMS and DCS (Fig 3), we have

Despite the good agreement between nTMS and DCS (Fig. 3), we have to be aware that these results strongly rely on many parameters, such as definition of resting motor threshold (rMT), the voltage at which CMAP is considered significant, registration

errors, navigation C59 wnt concentration errors of both systems, and brain shift after durotomy [23] and [24]. Therefore, it seems to be unlikely that nTMS is capable to completely replace intraoperative neuromonitoring (IOM). Yet, when the rolandic region is compromised by tumor growth, it is highly valuable to have another modality at hand, which confirms the results of DCS mapping. Compared to fMRI, nTMS is also less affected by the patient’s cooperation or claustrophobia. Further newly evolved possibilities of nTMS are to decide whether or not DCS is mandatory or not and it enhances IOM by guiding the DCS probe, thus accelerating DCS mapping significantly. The adaptation of nTMS motor mapping data for outlining functionally crucial seed regions was simple, and compatibility between the Nexstim eXimia 3.2 and iPlan® Cranial 3.0.1 using iPlan® Net was given by the DICOM standard and remained trouble-free when changing to iPlan® Cranial Unlimited (BrainLAB AG, Feldkirchen,

Germany). Traditional outlining of the primary motor cortex can be quite challenging when tumors affect the rolandic region. Mostly due to mass effects and edema. Such structural alteration Birinapant concentration with impairment of the anatomy causes an imprecise outlining of the cortical Tau-protein kinase seed region with the manual technique. Thus, even tracts from accidently included non-eloquent regions are incorporated and lead to a broader and therefore less specific definition of the CST. Furthermore, tumors within the CST or the precentral

gyrus can cause cerebral plasticity so that functionally important motor areas do not have to coincide anymore with standard anatomical landmarks, which are also regularly hard to identify [17], [25], [26] and [27]. Especially due to this matter, only nTMS data and not anatomical landmarks can reliably identify functionally crucial motor regions prior to surgery. Because our technique, shown in this work, is based on functional and not structural anatomy, it should provide a more accurate white matter fiber reconstruction. Nonetheless, we have to keep in mind that in large volume lesions or largely infiltrating tumors, nTMS might not be able to elicit MEPs in all fibers of the CST due to impairment of these fibers by tumor or edema. Therefore the tract might appear more compact than observed with traditional tractography. In most cases, these missing fibers are located around the tumor in the upper part of the tract in standard tractography, which seem to be missing in the nTMS-designed tracts.
