As a physiological index for evaluating the effects of dental tre

As a physiological index for evaluating the effects of dental treatment, the usefulness of encephalic waves has been suggested GDC-0199 ic50 [15]. When neuronal function in the cerebral cortex is absent due to Alzheimer-type dementia, the electrical potential

distribution is distorted. Therefore, Hara et al. [16] established the diagnosis method of neuronal dysfunction (DIMENSION), which quantitatively estimates synaptic neuronal function in the brain using electroencephalographs (EEG). EEG can be used to instantly record brain waves through the head skin using electrodes. Musha et al. [17] reported that DIMENSION could distinguish between Alzheimer-type dementia patients and healthy individuals, and that there were strong correlations between DIMENSION and brain blood flow measurement IOX1 results obtained using single photon emission computed tomography (SPECT), which is applied for the diagnosis of dementia, and the results of patient interviews (Mini-Mental State Examination). Jelic and Kowalski [18] reported that evidence for the diagnostic utility of resting EEG in dementia and mild cognitive impairment is still insufficient to establish this method for the initial evaluation of subjects with cognitive impairment in routine clinical practice. Indeed, MRI shows high-level diagnostic accuracy in Alzheimer’s disease, dementia, and cognitive impairment, and

is frequently used for a differential diagnosis in these diseases [19], [20], [21] and [22]. However, several reports described abnormal brain waves in Alzheimer’s disease patients using EEG analysis [23], [24], [25], [26] and [27]. The purpose of this study was not to diagnose dementia, but evaluate brain function activity using EEG. In this research, it was necessary to measure in a short time brain function of denture wearers who sought denture treatment at the prosthodontic clinic. Also, they had no suspected brain disease. MRI can only be used in facilities, which have the required equipment. MRI measurement is necessary 10 or 20 times compared

with EEG Rebamipide measurement. Furthermore, to estimate the brain function activity before and after denture treatment or before and after gum chewing, we need to catch dynamic changes in brain function activity. EEG can perform dynamic measurement, but MRI cannot. The advantages of EEG are as follows: (1) EEG measurements are possible at prosthodontic clinics which have the device. (2) EEG measurements can be performed in a short time, so changes in the brain activity before and after denture treatment or before and after gum chewing can be measured easily. (3) Dynamic EEG can be measured. (4) EEG can be measured without damaging the living body such as through radiation or a strong magnetic field. (5) The EEG system is relatively inexpensive. Considering the above merits, brain function activities are evaluated by DIMENSION analysis using EEG data [28] and [29].

04 s) only in the second dimension. β-Santalol, that contributes to a woody aroma, (1tR = 53.10 min, 2tR = 2.17 s) also co-eluted with (E)-4-methyl-3-hepten-2-one

(1tR = 53.10 min, 2tR = 3.45 s), which is similarly associated with woody aroma attributes ( Brenna et al., 2003). Ethyl 9-decenoate contributes to wine aroma with fruity notes (Zhao, Wang, Li, Pei, & Liu, 2011). This compound coeluted in the first dimension and partially Buparlisib solubility dmso coeluted in the second dimension with 5-ethyldihydro-2(3H)-furanone and 2-ethylhexanal. Fig. 4A shows the superimposed chromatographic peaks. Spectral deconvolution based on mass spectra differences is quite useful in this case, especially to separate ethyl 9-decenoate from 5-ethyldihydro-2(3H)-furanone and 2-ethylhexanal, because they also co-elute in the second dimension. In Fig. 4B, mass spectra of the three compounds are compared with mass spectra from the NIST library. The discriminant volatile compounds related to wines produced with five different grape cultivars are shown in Table 3. It is interesting to observe that Chardonnay/Pinot Noir wines were differentiated from other wines only by terpenes, including nerol, β-santalol and 4-carene. Two esters (diethyl malonate and ethyl 9-decenoate) were considered discriminants for Chardonnay wines. Cabernet Sauvignon wines were differentiated only by the furanones tetrahydro-2(2H)-pyranone

and 3-methyl-2(5H)-furanone. The use of HS-GC × GC/TOFMS

associated with multivariate check details analysis (Fisher ratio, PCA and LDA) to investigate the volatile composition of wines proved to be an interesting find more approach to differentiate wines according to their original grape cultivars and also to find potential markers of these grape cultivars. These results may help the wine industry to develop more effective quality control methods, in order to produce added value wines. Twelve volatile compounds chosen from a large set of original variables, obtained by GC × GC/TOFMS, were enough to discriminate 100% of wines elaborated from five different grapes. Among these 12 compounds, some partially coeluted with other components in the first chromatographic dimension (1D) and were more properly assigned, due to the extra selectivity provided by the second chromatographic dimension and spectral deconvolution.

001) from 2008.73 (assay number 4) to 4632.13 mg/100 g (assay number 8). The highest values for antioxidant capacity were observed in extraction with 85.0% methanol for 20 min at 45 °C. The RSM application on DPPH showed that the model was significant (p <   0.001), did not present lack of fit (p   = 0.24) and could explain 97.14% of all variance in data (( Radj2 = 0.94). The temperature (X2) significantly decreased the DPPH levels and consequently increased the antioxidant capacity. Longer times (X1) and higher concentrations (X3) decreased the antioxidant

capacity (higher values of EC50). Interations of time (X1) and temperature (X2) had a significantly negative effect, PD-1/PD-L1 inhibitor and time (X1) and concentration (X3) interations had a positive effect, according to Eq. (4): equation(4) Y=2514.98+260.04X1-402.34X2+182.52X3+218.72X12+1010.48X32-659.24X1X22+374.83X1X3. selleck chemical Thoo, Ho, Liang, Ho, and Tan (2010) found similar results, where samples with better antioxidant capacity by DPPH, were obtained by extraction at 45 °C. Temperature

influences the extraction, since heat renders the cell wall more permeable, enhances the solubility of the compounds, and the diffusion coeficient of the solvent. However, high temperatures (above 50 °C) can degrade some flavonoids such as antocyanins and procyanidins (Escribano-Bailón & Santos-Buelga, 2004). The FRAP values ranged statistically (p   < 0.001) from 1450.06 (assay number 11) to 1853.40 μM/100 g (central point). Extraction with 85.0% methanol for 15 min at 25 °C had the highest antioxidant capacity. The RSM application of FRAP values showed that the model was significant (p   < 0.001), could explain 97.48% of all variance in data (( Radj2 = 0.96),

and did not present lack of fit (p = 0.25). The quadatic regression coefficient of time (X1), temperature (X2) and concentration (X3) was negative and significant. The interation of time (X1) and temperature (X2) and interation of temperature (X2) and concentrations (X3) had a significantly negative effect on antioxidant capacity by FRAP assay, as shown in Eq. (5): equation(5) Y=1843.80-105.98X12-159.18X22-171.75X32-36.71X1X2-61.08X2X3. Acetone is another solvent commonly Miconazole used in the extraction of phenolic compounds (Kchaou et al., 2013 and Wijekoon et al., 2011). The mean values of the total phenolic content, total flavonoid content and antioxidant capacity measured by DPPH and FRAP of the extraction performed in apple with acetone solutions are shown in Table 4. In the extracts obtained from acetone solutions, total phenols ranged statistically (p < 0.001) from 438.03 (assay number 6) to 778.65 mg/100 g (assay number 3). The better yields were observed in the extraction with 65% acetone at 40 °C for 10 min. Total phenol values showed that the model was significant (p   < 0.001), did not present lack of fit (p   = 0.15), and could explain 96.85% of all variance in data (( Radj2 = 0.94).

i. 400 ppm), and water as another control. Treatments were conducted after the pathogen

inoculation spray had dried on the seedlings. Five replicates were performed for the container experiment; the containers were arranged in a randomized block design. All results were analyzed using Duncan’s multiple range test. Disease incidence was rated as the mean number of diseased lesions per container and the total number of lesions was counted. Disease severity was rated as the mean diameter of the lesions; all the lesions on two seedlings per container were measured using a Vernier caliper. The percentage of leaf area per seedling covered with lesions was estimated visually. The protection rate of disease incidence (PI) was calculated as PI (%) = (Nc − Nt)/(Nc × 100), where Nc = number of lesions in the control

learn more and Nt = number of lesions in the treatment sample. The inhibition rate (IR) of lesion size was defined as IR (%) = (Dc − Dt)/(Dc × 100), where Dc = mean diameter of lesions in the control and Dt = mean diameter of lesions in the treatment. The protection rate of disease severity (PS) was defined as PS (%) = (Ac − At)/(Ac × 100), where Ac = total area of lesions in the control [Nc × π × (Dc/2)2] and At = total area of lesions in the treatment [Nt × π × (Dt/2)2]. To test if B. subtilis HK-CSM-1 had antagonistic Bosutinib effects on the growth of C. panacicola, we first carried out a dual-culture test on a PDA medium. An inhibition zone was evident, produced by the inhibition of mycelial growth via the antifungal activity of B. subtilis HK-CSM-1 ( Fig. 1A). However, normal growth of the fungus was observed in the control ( Fig. 1B). Several previous studies have documented the antagonistic effects of beneficial C59 solubility dmso microorganisms towards fungal pathogens as a result

of the inhibition of conidial germination and inducement of germ tube swelling [4]. In our study, frequent and consistent hyphal swelling of C. panacicola mycelia was induced by cocultivation with B. subtilis HK-CSM-1 ( Fig. 1C). Together, these results indicate that B. subtilis HK-CSM-1 inhibits the growth of C. panacicola. We then investigated the possibility of using B. subtilis HK-CSM-1 as a biological control agent against C. panacicola in vivo and determined its efficacy relative to treatment with the chemical fungicide ITA. The fungicide demonstrated good control of anthracnose in ginseng leaves ( Fig. 2D). Interestingly, as shown in Fig. 2B, B. subtilis HK-CSM-1 effectively attenuated the infection of C. panacicola on ginseng seedlings, whereas symptoms of an advanced infection were observed on the water and TSB controls ( Figs. 2A and 2C). The number of infected lesions per container is indicated in Table 1. B. subtilis HK-CSM-1 was not significantly different (p < 0.05) from ITA ( Table 1) in control efficacy 14 d after inoculation with the pathogen.

An experimental study design could clarify the rapid effects of p

An experimental study design could clarify the rapid effects of phytoestrogens on estrogenic and androgenic plasma activities. Research also needs to be extended to both males and females of different age groups, who have specific hormone profiles and may therefore respond differently to chemical exposures. The results of this

explorative study are not yet readily interpretable. However, they demonstrate that it is possible to identify associations between sources of potential endocrine disruptors and measurements of estrogenic and androgenic activities in total plasma among a reasonably sized group of men. Because the total estrogenic and androgenic Selleck GDC0199 plasma activities reflect receptor activation by any xenobiotics present as well as by endogenous hormones, they also capture indirect effects such as interference with the bioavailability of endogenous hormones or competitive receptor binding. Comparing these measurements ON-01910 datasheet with findings regarding the levels of endogenous hormones or with internal measurements of specific chemicals or chemical derivatives could clarify

the endocrine disrupting potential of certain chemicals as well as their behavior within the human body. Measurements of total estrogenic and androgenic plasma activities could thereby help to better understand associations between potential exposure sources of endocrine disruptors and specific health outcomes in epidemiological studies.

“The prospective widespread usage of carbon nanotubes (CNTs) in industrial applications and consumer products and articles creates the Meloxicam potential for release of CNTs that could result in a possible increase of human and environmental exposure to CNTs (Gottschalk and Nowack, 2011 and Koehler et al., 2008). As a starting point to exposure assessment, exploring sources and pathways of release helps to identify relevant applications and situations where humans or the environment may encounter releases of CNTs. By tracking the life cycle of products, it is possible to explore whether and in which situations a release of CNTs from applications may occur (Upadhyayula et al., 2012). The focus of this review is on release as a prerequisite for exposure.

Kohda and Tanaka [44] reported crude preparations of several glyc

Kohda and Tanaka [44] reported crude preparations of several glycoside hydrolases for the hydrolysis of ginseng ginsenosides; cellulase and amylase exhibited very low hydrolytic activities, whereas pectinase, naringinase, and hesperidinase had much higher activities for hydrolyzing ginsenosides. A permeability study of Rapidase-treated red ginseng extract in

rat skin was conducted by using Franz diffusion cells. The polyphenol contents of the samples transported through the rat skin was significantly increased over time (Fig. 5). The skin permeability of the red ginseng extract treated with Rapidase was higher than that of the control. In particular, after 4 h, the skin permeability of the red ginseng extract treated with Rapidase showed a significant increase (p < 0.05) compared with that of the control. Although total polyphenol contents are similar in the presence or absence of Rapidase treatment, Rapidase treatment showed a significant improvement of skin permeability. This result suggests that Rapidase can also act on polyphenol glycosides to produce aglycone

forms of polyphenols. Recently, the study to maximize the bioactivity of plant extracts via the enzyme reaction has been performed in the cosmetic industry using natural compounds [45]. The bioactive ingredients of plants mostly include mixtures of compounds that are present in the form of aglycones and hydrophilic glycosides. However, Selleck GSK-3 inhibitor glycosides have some difficulties in their application for skin cosmetics attributable to their low skin permeability. By contrast, aglycone, a hydrophobic polyphenol, can permeate human skin [46]. Wiechers [47] reported that low molecular weight contributes to easier skin penetration; there is a size limitation for chemical compounds and drugs to be absorbed across the human skin barrier. Therefore, Bos and Meinardi [48] reported that certain skin penetration enhancers have low molecular weight. Thus, the hydrolysis of glycoside ingredients into their aglycone

forms has attracted attention as an effective means of enhancing the Epothilone B (EPO906, Patupilone) permeability and, consequently, bioactivity of extracts [45]. Most commercial ginseng products are produced from chemical processes such as solvent extractions and chromatographic purifications. These processes are complicated, costly, and are usually associated with low yields of active compounds such as ginsenosides, oligosaccharides, and polysaccharides. Enzymatic extraction was found to be an easy and rapid method for the separation and concentration of bioactive compounds. Therefore, Rapidase will be a major enzyme to enhance bioactive compounds in the development of health-oriented ginseng products via enzymatic processes.

For such trials to take place and to further support the characte

For such trials to take place and to further support the characterisation of genetic variation, Koskela et al. (2014) indicate the Saracatinib supplier importance of streamlining the international

processes of germplasm exchange for research purposes, in the light of the implementation of the Nagoya Protocol. Such research will also be supported by studies to advance developments in seed and in vitro storage technology as advocated by Pritchard et al. (2014), investigations which need to proceed beyond the species level to study intraspecific variation in storage characteristics ( Daws and Pritchard, 2008). Graudal et al. (2014) are positive about the potential to develop appropriate indicators to monitor tree genetic variation. This is because a range of ‘state’ indicators considered unrealistic only two decades ago can now be proposed for immediate implementation due to advances in geographic information systems, in high throughput molecular genotyping and in bioinformatics. Molecular markers, for example, are now much cheaper to generate and use, and, importantly, can be associated directly with adaptive variation (e.g., Funk et al., 2012, Hansen et al., 2012 and Neale and Kremer, 2011). Careful experimental design is however still required if the current disappointingly low level of application of molecular genetic data

to on-the-ground check details forest management is to the be increased (FAO, 2004 and Jamnadass et al., 2009). Wickneswari et al. (2014) stress that the monitoring of genetic variation at genes that directly relate to productivity and fitness is required to further explore the consequences of selective timber cutting in forests. This is because actual data on how changes in the genetic structure of logged tree populations influence production

volumes, timber quality and economic value are surprisingly limited, representing a major gap that must be filled. Graudal et al. (2014) note that the establishment of ‘Sentinel Landscapes’ in Africa, Asia and Latin America by the CGIAR Consortium Research Programme on Forests, Trees and Agroforestry (FTA, 2014), with each landscape spanning national boundaries and land use systems, provides a new opportunity for testing the validity of indicator methods. Advances in molecular genetic characterisation that include methods such as next-generation high-throughput DNA and RNA sequencing mean that the low percentage of tree species analysed genetically to date should increase rapidly in the next decade (Russell et al., 2014). An interesting dawning application is in tracking timber origins and species. This is needed to reduce the serious problem of illegal trade in many commercially important timbers, which leads to losses of billions of USD in the formal economy, as well as environmental and social concerns (Degen et al., 2013 and Lowe and Cross, 2011).

The orange dye channel is reserved for the CC5-labelled Internal Lane Standard 500 Pro (CC5 ILS 500 Pro) size standard. Unless otherwise specified, amplification reactions were performed in triplicate. Each 25 μL amplification selleck reaction contained 5 μL of PowerPlex® ESI/ESX Fast 5× Master Mix and 2.5 μL of the respective 10× Primer Pair Mix, with 17.5 μL available for purified DNA sample and amplification grade water. Direct amplification reactions were set up in the same way except that 5 μL of 5× AmpSolution™ Reagent and 12.5 μL of amplification grade water

(10.5 μL if performing an amplification with 2 μL of SwabSolution™ extract) were used to bring the volume to 25 μL. AmpSolution™ Reagent protects the amplification reaction against chemicals in the FTA® cards, SwabSolution™ and PunchSolution™ Reagents that would otherwise inhibit the PCR. The following direct amplification sample types were used from three donors each. 1. One 1.2 mm blood FTA® punch Unless specified otherwise, thermal cycling was performed on the GeneAmp® PCR System 9700 thermal cycler with a silver or gold-plated silver sample block (Life Technologies, Foster City, CA) using the cycling parameters described in the technical manuals [14], [15], [16] and [17]. These consisted

of an initial activation of the thermostable DNA polymerase at 96 °C for 1 minute, followed by 30 cycles (26 cycles for direct amplification) of dentauration at 96 °C for 5 s, annealing at 60 °C for 35 s and extension at 72 °C for 5 s. This was followed by a final extension at 60 °C for 2 min Epigenetics Compound Library ic50 and a ramp down to a 4 °C soak. Max ramp mode was used on the GeneAmp® PCR System 9700 thermal cycler. The same cycling protocol was followed for experiments conducted

on the 96-well (0.2 mL) Veriti® thermal cycler (Life Technologies, Foster City, CA) and the GeneAmp® PCR System 2720 thermal cycler (Life Technologies, Foster City, CA). Ramp rate was left at “100%” on the 96-well (0.2 mL) Veriti® Thermal Cycler. Amplified samples and allelic ladder were processed according to the technical manuals [14], [15], [16] and [17]. One microliter of amplification product or allelic ladder was combined with 10 μL Hi-Di™ formamide and 2 μL of CC5-labelled Internal Phenylethanolamine N-methyltransferase Lane Standard 500 Pro (CC5 ILS 500 Pro). Samples were heated to 95 °C for 3 min prior to quick chilling in a crushed wet-ice bath for at least 3 min Samples were injected at 3 kV for 5 s on an Applied Biosystems 3130 or 3130xl Genetic Analyzer and at 1.2 kV for 24 seconds on the Applied Biosystems 3500xL Genetic Analyzer. Data generated on the Applied Biosystems 3130 or 3130xl Genetic Analyzer were analyzed using GeneMapper®ID 3.2.1 software (Life Technologies, Foster City, CA) and a 50 RFU detection threshold whereas data generated on the Applied Biosystems 3500xL Genetic Analyzer were analyzed using GeneMapper®ID-X software (Life Technologies, Foster City, CA) and a 175 RFU detection threshold.

HIV-1 reverse transcripts were determined by PCR using primers specific for LTR/gag (Schmidtmayerova et al., 1998) and GSK-3 inhibitor review for GAPDH (sense 5′-TTC TGT CTT CCA CTC ACT CC-3′, antisense 5′-GTA TTC CCC CAG GTT TAC ATG-3′) in a 50 μl reaction volume containing 1 U of Taq DNA polymerase (Top-Bio, Czech Republic), 1x PCR buffer (10 mM Tris–HCl, pH 8.8; 50 mM KCl; 0.1% Triton X-100), 200 nM each primer, 200 μM dNTPs, MgCl2 (1 mM for LTR/gag; 0.75 mM for GAPDH) and sample DNA (1000 ng for LTR/gag; 200 ng for GAPDH. PCR conditions: initial denaturation 94 °C/4 min

and 35 cycles of 94 °C/30 s, 52 °C/30 s for LTR/gag or 57 °C/30 s for GAPDH, 72 °C/60 s, with final extension 72 °C/10 min. The PCR products were resolved using a 1.5% agarose gel electrophoresis in 1× TBE buffer and 0.5 μg/ml ethidium bromide, and visualized under UV transilluminator. Cells were collected and lysed in Laemmli reducing sample buffer, boiled and analyzed by SDS–PAGE and western blotting as previously described (Harlow and Lane, 1988 and Laemmli, 1970), using chemiluminescence (West Femto, Thermo Fisher Scientific – Pierce, Rockford, IL). For p24 antigen, the cell lysates were resolved on a 14% SDS–PAGE and detected using a monoclonal

antibody ND-1 (dilution 1:500; Exbio, Prague, Czech Republic) and a peroxidase-conjugated goat anti-mouse IgG (dilution 1:20,000; Sigma Co., St. Louis, MO). EGFP was detected using a Selleck Sunitinib 12% SDS–PAGE, a rabbit polyclonal antibody (dilution 1:1000; Exbio, Prague, Czech Republic) and a peroxidase-conjugated goat anti-rabbit IgG (dilution 1:20,000; MP Biomedicals – Cappel, Solon, OH), HO-1 was detected using a 10% SDS–PAGE, a rabbit polyclonal antibody (dilution 1:20,000; Abcam, Cambridge, United Kingdom) and a peroxidase-conjugated goat anti-rabbit IgG (dilution 1:20,000). β-Actin was detected on a 10% gel, using either a goat polyclonal antibody (dilution 1:200; Santa Cruz Biotechnology, Santa Cruz, CA) and a peroxidase-conjugated donkey anti-goat IgG (dilution 1:20,000; Jackson ImmunoResearch Thiamine-diphosphate kinase Laboratories,

West Grove, PA) or using a rabbit polyclonal antibody (dilution 1:7500; Abcam, Cambridge, United Kingdom) and a peroxidase-conjugated goat anti-rabbit IgG (dilution 1:20,000). Flow cytometer Canto II (Becton Dickinson) equipped with 3 lasers emitting at 488, 405 and 633 nm, and with 8 detectors was used. Flow cytometry measurements were performed using the Diva 6 software (Becton Dickinson, Franklin Lakes, NJ). Subsequent analyses of the flow cytometric data were performed using Diva 6 and/or FlowJo (Tree Star, Inc., Ashland, OR). At each time point, cells were collected, stained with a fluorochrome, and used for further analysis in the appropriate detecting channel. Ten thousand cells were collected upon gating on a FSC-A × SSC-A dot plot. The region used for further analysis contained live cells, as well as their apoptotic counterparts (Fig. 1).

This precludes participants from making the kind of comments that

This precludes participants from making the kind of comments that we elicited. Second, excluding indirect responses, we are left with a rate of 88% correct responses to underinformative utterances with scalar expressions, comparable to the 83% reported by Guasti et al. (2005, experiment 4) and the 93% reported by Papafragou

and Musolino (2003, experiment 1)2. This dispels any concerns that our task elicited fewer categorical rejections from the adults than other tried-and-tested paradigms. Instead, our task design has elicited relevant additional data: even when adults do not categorically reject underinformative utterances, they are not oblivious to pragmatic infelicity, and their responses to underinformative utterances reflect this. Children performed significantly better when the correct response depended exclusively on the logical meaning of scalar and non-scalar expressions than when it Gefitinib supplier also depended on informativeness. In the latter case, but not the former, they also performed worse than the adults. This is exactly the picture

documented in previous studies which has been interpreted as evidence that children lack some aspect of pragmatic competence. However, we propose an alternative explanation for children’s acceptance of underinformative utterances, namely that children are tolerant of pragmatic infelicity in binary judgment tasks. To test this claim directly, in the following experiment we give participants a ternary judgment task. If children are not sensitive to violations of informativeness, they should assign the same rating to underinformative and optimal utterances. FG-4592 chemical structure However, if children are sensitive to informativeness and also tolerant of violations of informativeness they should consistently choose the middle Succinyl-CoA value for underinformative utterances, reserving the highest and lowest value for optimal (true and informative) and false utterances respectively. Exactly the same items and scenarios were used as in experiment 1. However, instead of judging whether Mr. Caveman’s

response was right or wrong, participants were asked to reward his response using a 3-point scale consisting of different-sized strawberries. These strawberries are introduced as Mr. Caveman’s ‘favourite food’, and are depicted visually in a horizontal line on printed paper, with the smallest on the left and the biggest on the right, each strawberry being twice the size of the previous one. Each point in the scale was explicitly introduced with its label, ‘the small strawberry’, ‘the big strawberry’ and ‘the huge strawberry’. Previous studies in our lab (Katsos & Smith, 2010) using an earlier version of this task revealed that children of this age can give judgements using 5-point Likert-scales, so we did not administer training or special instructions on how to use this 3-point scale.
