, 2005 and Montes et al., 2010). A comparison of the two right panels of Fig. 6a illustrates PD-0332991 molecular weight the striking differences that can occur in the propagation of dynamical (δ′TSEδ′TSE) and spiciness (δ″TSEδ″TSE) signals, in this case with the spiciness signal extending more prominently equatorward. Similar differences occur in our other regional solutions, and have been noted previously by Nonaka and Xie, 2000 and Taguchi and Schneider, 2013. Equatorial response.   Fig. 6b illustrates the vertical structures of the dynamic and spiciness anomalies along the equator, plotting δTSE,δ′TSEδTSE,δ′TSE, and

δ″TSEδ″TSE fields averaged from 1 °S to 1 °N. Consistent with Fig. 6a (top panels), the deep dynamical signal δ′TSEδ′TSE ( Fig. 6b, middle panel) is spread throughout the equatorial ocean. There is also a near-surface, positive anomaly that is locally generated (see below). It is noteworthy that δ′TSEδ′TSE has fewer zero

crossings at the equator than it does in the forcing region ( Fig. 4b, middle-left panel south of 8 °S), an indication that either Rossby waves associated with higher-order vertical modes are preferentially damped or the large change in stratification modifies the structure of the modes. Also consistent with Fig. 6a, there is a strong, negative spiciness signal δ″TSEδ″TSE within the pycnocline selleck inhibitor ( Fig. 6b, bottom panel), which is advected to the equator from Region Mephenoxalone SE along the two pathways noted above. Below the pycnocline, there is a positive anomaly (bottom panel) near the western boundary. Most of it flows out of the basin as a deep part of the ITF (not shown; e.g., McCreary et al., 2007), with some bending eastward to join the southern

Tsuchiya Jet and the lower part of the EUC. There are also negative δ″TSEδ″TSE and positive δ′TSEδ′TSE signals above the pycnocline. Because of surface fluxes, however, these signals cannot be interpreted as arising solely from the remote forcing region. The negative δ″TSEδ″TSE signal is advected along the equator within the pycnocline by the EUC and is mixed upward into the surface layer in the eastern Pacific. The heat flux into the ocean is increased there, reducing the negative temperature anomaly (Fig. 6b, top panel) and leaving behind a negative salinity anomaly. At the same time, evaporation is reduced owing to the lower SST while precipitation is not affected (Section 2.1), enhancing the negative salinity anomaly. This anomaly is advected westward by the surface South Equatorial Current while the negative temperature anomaly is almost erased by the surface heating before reaching the western Pacific. Since the dominance of negative salinity anomaly implies a negative density anomaly in the western Pacific, the vanishing temperature anomaly there is projected onto δ′T>0δ′T>0 (see Eq. A.2c), resulting in δ″T<0δ″T<0 since δT=δ′T+δ″TδT=δ′T+δ″T.

The data were Smad inhibitor analyzed in GraphPad Prism 5.00® software (GraphPad Software, Inc., San Diego, CA) using one-way analysis of variance (ANOVA) followed by Dunnett’s test for multiple comparisons or Student’s t-tests to compare two groups. Non-parametric data were compared using the Kruskal–Wallis test followed by Dunn’s test, and percent data from two groups were compared using the Mann–Whitney test. Data are expressed as the mean ± SD,

or as the median with range, and differences were considered statistically significant at p < 0.05. We performed transcriptome analysis on isolated splenic NK cells from 20 mice (5 mice/group) that were treated daily by gavage

for 14 days with ptaquiloside and/or selenium to identify transcripts that were associated with ptaquiloside-induced immunosuppression. The gene expression profiles from the Pt, PtSe and Se experimental groups, compared with the control group, showed 872, 302 and 489 altered genes, RGFP966 supplier respectively (Table 1). Of the up-regulated gene transcripts from all experimental groups, 123 were mapped to biological processes, from which we highlighted five, although, as shown in Fig. 2, none had high enrichment scores (≥1.3). The Pt and Se groups showed a very different pattern of distribution of differentially expressed genes in these 5 biological processes, whereas no particular biological process was favored in the PtSe group. The corresponding genes for each enriched GO term are listed in Table 2 and in Supplementary Table 1. When considering

gene transcripts that could be related to the immunosuppressive effects of ptaquiloside, we did not find genes directly related to this effect, but selected the genes metallothionein all 1 (Mt1) and metallothionein 2 (Mt2), which are involved in cellular ion homeostasis and act as zinc regulator that is essential to normal immune function. Ptaquiloside treatment increased the expression of these gene transcripts 2.9-fold (p < 0.001758) and 3.0-fold (p < 0.025148) compared with the control group, respectively. Supplementary Table S1.   The GO terms are over-represented among the genes whose expression was up regulated in the experimental groups vs. the control group. Each category biological process (GOTERM_BP_FAT) is represented by at least 3 genes. Of the down-regulated gene transcripts, 1174 were mapped to a wide range of biological processes. Transcripts with enrichment scores ≥1.3 for at least one of these groups are presented in Fig. 3. These data showed no specific biological process that was associated with ptaquiloside-induced immunosuppression in NK cells. The corresponding genes for each enriched GO term are listed in Supplementary Table 2. Supplementary Table S2.   The GO terms are over-represented among the genes whose expression was up regulated in the experimental groups vs. the control group.

However, in many cases irreversible inactivation processes (which may involve a reversibly unfolded form as an intermediate) occur on a timescale comparable with that of the assay. Under these circumstances the reaction progress at higher temperatures is strongly curved, as enzyme is inactivated. Then it is difficult to estimate a meaningful

initial rate. Some studies will define activity based on a single time point measurement of product formed (or substrate consumed). In studies of temperature effects this is a particularly dangerous design. With progress selleck curve in reality strongly curved, the estimate of “activity” (based on an assumption of linear progress) will be higher the shorter the choice of reaction time. As temperature increases, the rate at the shortest times may continue to increase due to normal thermal effects, but faster inactivation will increase curvature of progress. Hence the apparent “optimum temperature” will depend on the arbitrary choice of assay duration, being highest for the shortest assays. • It is necessary that the buffer in which the thermal exposure is carried out is described completely. Ionic strength may play a role (see also Bisswanger,

2014). Presence of additives can significantly affect the temperature optimum. This includes presence of simple ions. Calcium ion, for example, affects both the activity INCB024360 molecular weight and/or stability of several enzymes. Thermal stability is the most frequently studied parameter in order to assess the stability of the enzyme in general terms. It is not an incorrect trend in as much as a more thermostable enzyme is more likely to be stable under other harsh conditions as well, for example, when exposed to organic solvents. The inactivation mechanisms of an enzyme under all

conditions involve presumably unfolding of the protein chain as the first common step (Gupta, 1993). However, in recent years, “native-like structures” are known to aggregate (Bemporad et al., 2012). At the same time, aggregation need not result in inactivation. As already mentioned, we have recently reported an aggregated form of α-chymotrypsin which shows higher activity in both aqueous buffers and non-aqueous media (Rather et al., 2012). Stabilization under extreme pH conditions is also a desirable goal in several cases. Stability of proteases Carnitine palmitoyltransferase II under alkaline conditions, for example, is useful for incorporating these enzymes in detergents. Often, such stability or stabilization is reported when the biocatalyst prepared is dissolved or suspended in aqueous buffers. In terms of validity of the data, that is not a problem provided all conditions are properly defined. This is necessary since for a protein solution, stability strongly depends upon the concentration, the nature of the buffer and the presence of any other additive. From practical point of view, such data merely provides a rough guideline.

3–1.5). Fig. 2A shows RT-sorted violation minus control difference ERPimages of all participants’ single trial EEG at PZ, aligned both to the onset of words inducing a morphosyntactic violation, and to RT, and the corresponding ERP. Onset-aligned ERPimages (150-epoch Gaussian smoothing) revealed an onset-aligned P600 with a broad, flat morphology, whereas in RT-aligned ERPs, the component peaked sharply, corresponding to a focused positive component in the RT-locked ERPimage. Semantic violation difference ERPimages (see Fig. 2B) reveal a similar RT-aligned

late positivity and a stimulus-aligned N400. To quantify onset and reaction time locking, we employed three measures: RT bin peak latencies, Woody filter estimates of component latency, and response- versus phase-locked ITC. For the syntactic violation condition, bin latency strictly increased with bin RT and RT bins were unlikely

Belnacasan concentration to reflect activity with identical latency (corrected F(3, 76) = 28; p < 0.0001). Bin latency monotonically rose with bin RT (mean 33% fractional area latency and mean bin RT for fastest to slowest bin: 770/606, 854/760, 926/920 and 1037/1190 ms; Spearman’s rho = 1). RT quartile-binned ERP latencies also correlated with mean bin RT for semantic violation trials (rho = 1). Woody filter-estimated single-trial latencies of the late positivity following syntactic violations correlated strongly with single-trial RT (95% CI: .5, .73), but the N400 following semantic violations did not (95% CI: −.1, .22). During the P600 peak window, phase locking of low-frequency activity (as measured by ITC) was greater for RT-aligned than for onset-aligned trials selleck chemicals (95%

CI: 5.4–11% greater ITC for RT-aligned trials). Parameter estimates for the Woody filter and ITC analyses are summarised in Table 1. mafosfamide The present study used single-trial EEG analyses to distinguish response – from stimulus-aligned effects in a linguistic deviancy detection task including button presses directly following critical parts of the sentence. The late positive EEG deflection following linguistically deviant material was strictly RT aligned, with no distinct, second positive peak aligned to stimulus onset. The N400 following semantic deviations behaved like an exogenous component in that it was stimulus – rather than response-aligned (compatible with Cummings et al., 2006). These results confirm an important prediction of the P600-as-LC/NE-P3 perspective. A dissociation between RT and P600 would have falsified this theory; the positive finding allows for a neurophysiological grounding of the P600 by association with the LC/NE system (Nieuwenhuis et al., 2005). It could be argued that the repetitive nature of our stimuli and our explicit task caused the sentences to be perceived in a more task-heavy processing mode, causing the appearance of a P3-like component instead of the components expected for more naturalistic stimuli.

Each electrode chip was fabricated by a semiconducting processes including a photoresist coating, patterning, lift off, and passivation. As can be seen in Fig. 1(a), approximately 250 chips on a 4 in glass wafer were fabricated for each process. A central circle shaped Au electrode with an area of π mm2 was utilized as the working electrode ( Fig 1(b)). An Au-electrode printed circuit board Cyclopamine mouse (PCB) chip was fabricated by an electroplating method and two types of PCB chips were made for use in other applications ( Fig 1(c and d)). Functionalization of GO nanosheets with MPHs was achieved by following a previous

study Veerapandian et al. Briefly, 200 μL of MPHs and 40 μL of 3-APTES were added to a tube containing anhydrous C2H5OH and kept for 10 h. After completion of the reaction process, FGO was drop-cast onto the oxygen plasma cleaned Au electrode PCB chip and allowed to evaporate at room temperature for 1 h. After modification of each Au electrode on the wafer, multiple layers were spin coated on the wafer. These layers were composed of a silane coupling layer on top of the FGO-Au electrode

followed by GOX composites, nafion, a silane coupling layer, and a restricted permeable polymer layer to form the multilayer-FGO-Au electrode. A customized reading platform was designed and built for the experiment. Fig. 2(a) shows the layout of the read out main board, the capable analog signal range of the system is between +5 and −5 V. As can be seen in Fig. 2(b), indicated with arrow, five different chips can be placed into the slots Inhibitor Library supplier for performing simultaneous measurements of different concentrations of glucose in TES and urine and between-run tests in same

concentration of glucose. All experiments were performed at room temperature in a 5 mL of collected urine samples and TES buffer for characterization. All amperometric measurements were performed at a working electrode potential of +0.6 V. The concentration of glucose in the TES buffer was examined by the fabricated Au-PCBs and the customized platform and the resultant images are displayed in Fig. 3. As can be seen in Fig. 3(a), the amperometric response with Niclosamide glucose concentration has strong proportionality to the concentration as it increases. Fig. 3(b) shows the amperometric responses measured 7 s after the immersion of five different chips with their variations from the mean values on each concentration. The between-run results show that their variations are within 6% from their mean values. Such materials including Ag/AgCl and Pt were not used as reference and auxiliary electrodes in this study despite these being the conventionally used materials in most electrochemical systems. Instead, we used an Au substrate as reference and auxiliary to reduce cost of chip production and increase stability during the field measurements.

, 2000 and Sollod et al., 2005). Although the major toxins of spider venoms are neurotoxic peptides, which act on a vast array of ion channels ( Kushmerick et al., 1999, Escoubas et al., 2000, Gomez et al., 2002, Matavel et al., 2002 and King and Hardy, 2013), non-neurotoxic peptides and also non-peptidic molecules have been described ( Bento et al., 1993, Marangoni et al., 1993, Rego et al.,

1996 and Rash and Hodgson, 2002). Lasiodora spiders are members of Theraphosidae family (suborder Mygalomorphae). They are commonly known in Brazil as caranguejeiras. The different species of Lasiodora spiders are difficult to distinguish ( Brazil and Vellard, 1926). These spiders, as predators, use their venom to feed on a variety of both vertebrate and invertebrate prey. Moreover, the ability to paralyze higher vertebrates makes the venoms of all mygalomorph spiders intriguing sources of compounds for Rucaparib the study Venetoclax of various receptors in vertebrates

( Escoubas and Rash, 2004). Reports on bites in humans caused by mygalomorph spiders are rare. The clinical symptoms observed after the bite are local pain, edema and erythema (Lucas et al., 1994 and Isbister et al., 2003). Lasiodora sp. spider venom has not been systematically studied. However, even venoms with low human toxicity can be sources for interesting physiological research ( Escoubas crotamiton and Rash, 2004). We have previously described that Lasiodora sp. crude venom inhibits L-type Ca2+ channels (Cav1) and modulates the activity of Na+ channel in GH3 cells ( Kushmerick et al., 2001). Vieira et al. (2004) identified three toxins expressed by the Lasiodora sp. venom gland. These toxins, named LTx1, LTx2 and LTx3, showed significant similarity with other toxins from Lasiodora parahybana, Eurypelma californicum, Brachypelma smithii and Selenocosmia huwena spider venoms. Dutra et al. (2008) observed that recombinant LTx2 blocks Cav1 channels in BC3H1 cells.

Our research group has also described the action of Lasiodora sp. venom on the isolated rat heart. This venom caused concentration-dependent bradycardia, with transient cardiac arrest and rhythm disturbances. Therefore, the authors suggested that Lasiodora crude venom evokes vesicular release of acetylcholine from parasympathetic nerve terminals by activating tetrodotoxin-resistant Na+ channels ( Kalapothakis et al., 2003). Thus, Lasiodora sp. venom may be a potential source of active toxins in various physiological systems, including the cardiovascular system. Many venom components, including bradykinin-potentiating peptides, sarafotoxins, and natriuretic peptides have significant cardiovascular effects ( Hodgson and Isbister, 2009 and Camargo et al., 2012). The aim of the present work was to characterize the pharmacological action of Lasiodora sp.

9 and 21 Levels of IFN-γ, IL-2, and CXCL10 in QFT-IT supernatant were significantly higher in TB patients than in normal controls whereas

none of the 3 analytes clearly differentiated between TB and LTBI as previously reported. 9, 22 and 23 These data indicate that assessment of a combination of IL-2 and CXCL10 may enhance the sensitivity of IGRA that measures only IFN-γ levels for diagnosis of M. tb infection. In addition, serum VEGF-A concentrations may serve as a biomarker to discriminate TB from LTBI. The relatively low specificity of serum VEGF-A concentrations may be improved by the combined measurement of IFN-γ, IL-2 and CXCL10 in response to M. tb antigens. Molecular tests have high specificity and sensitivity for rapid diagnosis and differentiation between pulmonary TB and NTM diseases, 5 and 6 but our data also provide a panel of serum cytokines Pifithrin�� (IL-2, IL-9, IL-13, IL-17, TNF-α and sCD40L) for differential diagnosis of active TB and NTM (P < 0.01). This panel may aid in early diagnosis prior to identification of clinical isolates by culture. CD40L (CD154) is a co-stimulatory molecule that plays a role in enhancing cell-mediated immunity to intracellular pathogens by inducing IL-12, which subsequently generates Th1-type cytokines through interactions with CD40 on macrophages click here or dendritic cells.24 Defective CD40L expression in PBMCs from TB patients contributes

to decreased IFN-γ production by PBMCs.25 Significantly higher levels of plasma sCD40L is present in plasma from TB patients in the fifth week of anti-TB treatment compared to pre-treatment,7 which is consistent with our findings. However, sCD40L

responses did not change significantly in response to M. tb antigens. It has been suggested that the IGRA is not appropriate as a monitoring tool for anti-TB treatment due to the substantial proportion of patients with positive QFT-IT (46%) and T-SPOT.TB® (79%) results after TB treatment. 26 There was no difference in IP-10 levels of QFT-IT plasma between pre- and post-treatment whereas significant changes in IP-10 release were observed in response to RD1 selected peptides (ESAT-6 and CFP-10). 27 Our study also showed no significant change in IP-10 levels of QFT-IT plasma between baseline and post-treatment. Meanwhile, Non-specific serine/threonine protein kinase both the magnitude of IFN-γ responses and the proportion of the responders showing high IFN-γ production (>1000 pg/mL) were significantly reduced post-treatment (P < 0.001). Rapid decreases in TNF-α and IL-2 responses and the percentage of responders correlated with M. tb sputum conversion in culture after 2 months of treatment. These results suggest that screening levels of serum sCD40L together with M. tb antigen-specific IFN-γ, TNF-α, and IL-2 responses may help evaluate drug efficacy, particularly the early therapeutic effect, in TB patients. However, our findings of M.

By creating paullones able to bind to ruthenium(II) and osmium(II) arene moieties, we expected to reduce the encountered problems markedly. Moreover, synergistic effects and the differing targets of metals and ligands could be an advantage for inhibiting cancer cell

growth. Indolobenzazepines with the general formula [MIICl(η6-p-cymene)L]Cl (L = L1 or L2; M = Ru or Os) ( Fig. 1) have been synthesized and characterized previously [13]. These substances have shown their potency in a cytotoxicity test in three human cancer cell lines, Trichostatin A purchase with IC50 values in the lower micromolar range. Hydrolysis behavior and reactivity to 5′-GMP were also reported. High cytotoxic activity was the reason for further studies on AZD6244 purchase their impact on human cancer cells. Because of the known Cdk-inhibitory activity of the metal-free paullones, inhibition of Cdk2/cyclin E was also investigated in a cell-free assay with the metal complexes. Effects on the cell cycle were quantified by flow cytometry, and the metal accumulation in the cells, inhibition of DNA synthesis and induction of apoptosis were

compared to cytotoxic potency. Compounds 1–4 were prepared as described previously [13]. For all experiments, the compounds were first dissolved in DMSO and then diluted in medium/buffer as appropriate. Flavopiridol was kindly provided by Sanofi-Aventis. CH1 (ovarian carcinoma, human) cells were donated by Lloyd R. Kelland (CRC Centre for Cancer Therapeutics, Institute of Cancer Research, Sutton, U.K.). SW480 (colon adenocarcinoma, human)

and A549 (non-small cell lung cancer, human) cells were kindly provided by Brigitte Marian (Institute of Cancer Research, Department of Medicine I, Medical University of Vienna, Austria). Prostate carcinoma cell line LNCaP, mammary gland carcinoma cell line T47D as well as the gastric carcinoma cell line N87 were purchased from the American Type Culture Collection (ATCC). Cells were grown without antibiotics in 75-cm2 culture flasks Carnitine dehydrogenase (Iwaki/Asahi Technoglass) as adherent monolayer cultures in minimal essential medium (MEM) (for CH1, SW480 and A549 cells) or in RPMI 1640 medium (for LNCaP, N87 and T47D cells), both media supplemented with 10% heat-inactivated fetal bovine serum and 4 mM l-glutamine, but only MEM supplemented with 1 mM sodium pyruvate and 1% non-essential amino acids (from 100 × ready-to-use stock) (all purchased from Sigma-Aldrich) without antibiotics. Cultures were maintained at 37 °C in a humidified atmosphere containing 5% CO2 and 95% air. Cytotoxicity in the cell lines mentioned above was determined by the colorimetric MTT assay (MTT = 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide, purchased from Sigma-Aldrich).

“The 1 December 2013 edition of the Sunday Times featured an article entitled ‘Starkers, sinuous and gutsy and that’s just her eel’. It provided a photograph of the 45 year old ex X-Files actress Gillian Anderson, naked, but hiding her ‘altogether now’ with a dead conger eel (Conger conger) draped around her shoulders. Intrigued, I read on. Apparently, the actress is a supporter of the charity Fishlove and the conger eel is threatened with extirpation, if not extinction, by fishing activities.

Now, I did not know this and so am grateful to Gillian not just for her picture but also for the information that has allowed MAPK Inhibitor Library mouse 3-mercaptopyruvate sulfurtransferase me to examine this topic more closely. Figure options Download full-size image Download as PowerPoint slide The European Conger conger is the largest eel in the world and native to the Northeast Atlantic, including the Mediterranean Sea. The long, anguilliform, and grey-black, conger has a usual length of 150 cm but the largest eel caught in England was snared off Falmouth in Cornwall and weighed 95 kg. That’s more than I weigh! The world record, however, is held by Iceland for one individual weighing 139 kg. Now, that’s a big fish. The head is conical, flattened dorso-ventrally, with forward pointing malevolant eyes set above a brutish snout containing rows of conical, needle-sharp, teeth. The species usually lives among subtidal rocky habitats, wrecks, reefs and rough ground, sometimes sharing its refuge with moray eels, and from which they emerge at night to hunt. Congers mainly feed on fish, cephalopods, and crustaceans. Strangely, and something else I did not know (although I should since this is well known for its smaller cousin, Anguilla anguilla) congers reproduce only once in their lives, at an age of 5–15 years, but with females producing millions of eggs. The only known conger eel spawning site is located in the Mediterranean, near Sardinia.

This region of chromosome 2BS has a pleiotropic effect on both

powdery mildew and stripe rust responses and therefore could be useful in breeding for resistance to both diseases by marker assisted selection. QPm.caas-3BS, identified in marker interval Xwmc366–Xgwm77 on chromosome 3BS and contributed by Pingyuan 50, explained 9.1% of the phenotypic variation. Chen et al. [43] reported a QTL linked with Xwms533 on the short arm of chromosome 3B in Line 2174 with a genetic distance of about 56 cM from QPm.caas-3BS [35]. Donini et al. [44] mapped Pm13, derived from Ae. longissimum, to a similar selleck chemicals region on 3BS using RFLP markers. QPm.caas-3BS, however, seems to be a new QTL for powdery mildew resistance based on chromosomal location and origin. QPm.caas-3BL was mapped to the centromeric region of chromosome 3BL between SSR markers Xwmc527 and Xwmc418, explaining 18.1% of the phenotypic variance. It was contributed by Mingxian 169. Race specific resistance gene Pm41 in wild emmer was mapped to chromosome 3BL, but at a genetic distance of about

34 cM from QPm.caas-3BL [45]. Although the genetic distance between QPm.caas-3BS and QPm.caas-3BL is less than 10 cM [35], we considered them as two QTL check details due to their locations on different chromosome 3B arms. No other QTL for powdery mildew resistance have been reported on chromosome 3BL. QPm.caas-5AL in marker interval Xwmc410–Xbarc261 explained 10.2% of the phenotypic variance. Sources of previously mapped QTL in this chromosome include Folke [1], Saar [20], Triticum militinae [46], and Forno [12] with genetic distances of 80, 80, 77, and 68 cM, respectively, from QPm.caas-5AL based on the wheat consensus map  [35]. This appears to be a new locus for powdery mildew APR. In addition, the QTL QYr.caas-5AL

[22] was mapped in the same region of this Pingyuan 50/Mingxian 169 population, suggesting the possibility of a pleiotropic APR locus conferring resistance to both powdery mildew and stripe rust. Yr48, for partial resistance to stripe rust was mapped to the same position PDK4 [47]. This locus needs further investigation to determine whether it confers pleiotropic powdery mildew and stripe rust resistances. Pingyuan 50 is considered a valuable source of APR to both stripe rust and powdery mildew in local wheat breeding programs, and three QTL for APR to stripe rust were mapped in Pingyuan 50 [20]. In the present study, four QTL for APR to powdery mildew were mapped in the same population, and three of them were in Pingyuan 50. Although these QTL were not detected across all environments, QPm.caas-2BS.2 and QPm.caas-5AL were mapped to the same chromosome regions as QYr.caas-2BS and QYr.caas-5AL, respectively, for APR to stripe rust, indicating possible pleiotropic genes for APR to both powdery mildew and stripe rust in Pingyuan 50. Gene pyramiding is a useful approach to enhance disease resistance and a number of genes can be accumulated in a single line.
