Chitosan color was found through Minolta system (CR-300, Minolta Corporation, USA). Color was measured from three-dimensional color diagram (L-a-b), and numerical values (a-b) were converted in Hue angle according Eq. (4) (Srinivasa et al., 2004): equation(4) Hab=tan−1(a/b)Hab=tan−1(a/b)where, Hab is Hue angle (°), “a” is chromaticity from green to red and “b” is chromaticity from blue to yellow. Powder grain-size analysis was carried out in standardized mesh screen. The average diameter was calculated by definition of Sauter (Eq. (5)): equation(5) D¯Sauter=1∑ΔXiDmiwhere,

DSauter is the average diameter of Sauter (m), ΔXi is the weight fraction of particles size Dmi (%) and Dmi is the arithmetic average diameter PD-0332991 ic50 between two screens (m). Thermogravimetric (TG and DTG) curves were obtained in a thermobalance (TA Instruments, DSC 2010, USA), with a heating rate 10 °C min−1 under modified Anti-diabetic Compound Library atmosphere through N2 (50 mL min−1), the amount of

samples used was in the range of 1–5 mg in platinum pan in the temperature range of 20–800 °C (Yoshida, Bastos, & Franco, 2010). Chitosan powder was characterized by scanning electron microscopy, SEM (Jeol, JSM- 6060, Japan) (Yen & Mau, 2007). Chitosan characteristic bands and deacetylation degree were verified through FT-IR analysis. Chitosan powder was macerated and submitted to the spectroscopic determination in the region of the infra-red ray (Prestige 21, 210045, Japan), using the technique of diffuse reflectance in potassium bromide (Yen & Mau, 2007). Deacetylation degree was determined according to Eq.(6) (Cervera et al., 2004): equation(6) %DD=87.8−[3(AC=O/A−OH)]where, %DD is chitosan deacetylation old degree (%), AC=O is absorbance of C O group and A−OH is absorbance of –OH group. The responses considered in the drying experiments were compared statistically using Tukey test by the software Statistica 6.0 (Statsoft, USA), with difference significance level of 95% (p ≤ 0.05). Chitosan paste obtained

showed moisture content 94 ± 0.1 g 100 g−1 (wet basis), ashes 0.04 ± 0.01 g 100 g−1, N-chitosan 5 ± 1.0 g 100 g−1, molecular weight 140 ± 2 kDa and %DD 85 ± 1%. For drying experiments the chitosan paste was diluted until 4 g 100 g−1 solids. Through pressure drop velocity curves, the air drying velocity used in the experiments to guarantee spouted stability was determined. The pressure drop velocity curves obtained were similar to the generic pressure drop velocity curve showed by Mathur and Epstein (1974). In slot-rectangular geometry minimum spouting, the velocities found were 0.88 m s−1, 0.87 m s−1 and 0.85 m s−1 for temperatures of 90, 100 and 110 °C, respectively. In conical-cylindrical geometry minimum spouting, the velocities were 0.62 m s−1, 0.61 m s−1, 0.60 m s−1, for temperatures of 90, 100 and 110 °C, respectively. Chitosan paste was fed into the bed.

Il confronto fra vittoria “tecnica” nel gioco e raggiungimento di obiettivi di ESS, suggerisce di considerare i giochi per l׳ESS come finalizzati a costruire innanzi tutto una visione integrata, valoriale e strategica, necessaria a ottenere equilibri sostenibili

altrimenti solo “tecnici” o impreparati al cambiamento. La riflessione sulla necessità di tale visione integrata dovrebbe essere anche alla base del debriefing, indipendentemente dal gioco. Tali risultati evidenziano come giochi finalizzati all׳ESS costruiti sulla TdG permettano di definire operativamente l׳ESS come un׳educazione alla scelta di strategie comportamentali dinamiche, in base all׳interazione learn more dei saperi e dei valori soggiacenti all׳identità dell׳individuo con la sua realtà ambientale e socioeconomica. La TdG andrebbe sistematicamente

applicata nella sperimentazione o creazione di giochi per l׳ESS, basati su studi di caso proposti dagli stessi giocatori, spinti a condividere l׳analisi dei saperi necessari a interpretare il problema che vogliono affrontare e dei valori che vi riconoscono coinvolti, ma lasciando la scelta/realizzazione del gioco al docente. Questo lavoro apre diverse prospettive di ricerca: la ricchezza dei dati della SPC suggerisce di estenderne il campione e costruire modelli probabilistici quantitativi; l׳interpretazione in termini di visione valoriale e strategica è efficace, ma forse limitata al tipo molto semplice di gioco utilizzato: MK-1775 purchase altri dovrebbero essere realizzati e sperimentati;

data infine l׳esiguità dei campioni, elementi come il genere dei giocatori o lo studio dei loro saperi dovrebbero Acesulfame Potassium essere considerati.

“With the development of the World Wide Web, knowledge has become easily accessible to most people in all fields. Accompanying this accessibility, new constraints emerged for both teachers and learners: finding appropriate information on one hand and constructing meaningful knowledge within this wheat of information on the other hand. Indeed, once the information found, it still remains to verify their truthfulness, and to be able to link them together in order to construct, in precise, logic and explicit ways, a solid and reliable framework of knowledge. This requires understanding, analyzing, and evaluating what has been learned, and corresponds to a high degree of scientific expertise and advanced thinking skills. Teachers sometimes emphasize on memorizing information or specific terms (Mayer, 2002).

1 to derive a final feature BAY 73-4506 cost set. Parameters for the SCAD-SVM method were set to 1000 maximum iterations and 500 minimum evaluations. The n.threshold parameter for the PAM classification was set to 30, and the maxRuns parameter

for the RF-Boruta algorithm to 300. All other parameters were set to default values (for a detailed description of the parameter settings, refer to the documentation of the bootfs package). Abundance and co-occurrence of selected features were visualized graphically as network, termed the importance graph in the bootfs package. Parameters were set to vlabel.cex = 6, max_node_cex = 20, node.filter = 17, vlabel.cex.min = 0.8, vlabel.cex.max = 4, filter = 17, ewprop = 1.4, max_edge_cex=15. A decision rule was defined for the risk classification by setting up a logistic regression model for classifying the histologic grade depending on the protein expression levels of the selected biomarkers. Considering a binary response variable Y   (i.e. histologic grade, where G1 is coded as y   = 0 and G3 as y   = 1) the model is written as: P(Y=1|X=x)=π(x)P(Y=1|X=x)=π(x) [R2LC]=logit(π(x))=log(π(x)1−π(x))=β0+β1×1+β2×2+⋯+βpxp+ϵwhere X   is an N   × p  -matrix of RPPA derived protein expression values, N

  is the number of samples, CP 690550 and p   is the number of predictor variables. β is the vector of p   + 1 coefficients to be estimated (including an intercept term β0) and ϵ   is the random error component in the model. Thus, x = [x1, x2, …, xp] is a vector of predictors for one sample. The training matrix is log transformed and subsequently standardized by subtracting the overall median and dividing by the overall median absolute deviation (MAD) for each data

point. From this standardized training Metformin mouse matrix X the final coefficients βˆ are estimated using maximum likelihood estimation and are subsequently used for the calculation of the RPPA Risk Logistic Classification (R2LC) score. To classify a new sample, we standardized the predictor protein intensities for the 4 markers by subtracting the median and dividing by the MAD. Western blotting was done as described previously [20]. In brief, tumor lysates were prepared as described above and 20 µg total protein of representative tumor samples were used for blotting and subsequent incubation with antibodies specific for caveolin-1 (ab32577, Abcam), NDKA (5353, Cell Signaling Technologies), and RPS6 (2217, Cell Signaling Technologies). As a loading control, an antibody directed against β-actin (69,100, MP Biomedicals) was used. Total RNA was isolated from tumor samples using the miRNeasy Mini kit (Qiagen) according to manufacturer’s instructions. Quality control of total RNA as well as labeling and hybridization to Sentrix Human HT-12 v4 BeadChips (Illumina) was performed at the DKFZ Proteomics and Genomics Core Facility. Data were normalized using the quantile algorithm of the Bioconductor limma package [27].

, 2000), including one commercially available biochemical identification system (API 20E and API 20NE, Biomerieux, France). Antimicrobial susceptibility of all Gram-negative bacterial strains isolated either from the environmental water or from the mucus of P. motoro stingrays was determined by the standard disk diffusion method ( Bauer et al., 1966) utilizing commercially available sensitivity discs and Mueller-Hinton Agar. The results were evaluated according to the NCCLS, 2004 guidelines. The following antibiotics were tested: amikacin (AMI), amoxicillin/clavulanic acid (AMC), ampicillin (AMP), cephalotin (CFL), ceftazidime (CAZ),

ciprofloxacin (CIP), chloramphenicol (CLO), trimethoprim/sulfamethoxazole (SUT), streptomycin (EST) and tetracycline (TET). For quality control the test Gefitinib price Saracatinib was run against the following ATCC strains: Escherichia coli 25922 and P. aeruginosa 27853. Blood-agar culture plates were prepared according to Beutin et al. (1989). Briefly, 1.5 g of TSA (Tryptic Soy Agar) re-suspended in a 10 mM solution of CaCl2 was autoclave. When the temperature of the agar fell to 45 °C, goat red cells previously washed three times in PBS pH 7.2 were then added to the agar

until a final concentration of 5% was reached. The agar was then added to petri dish plates (20 mL per plate), left to solidify and kept at 4 °C until use. Forty microliters of bacterial culture previously grown in TSB (Tryptic Soy Broth) for Rebamipide 18 h at 37 °C were added in triplicates to 3 mL of TSB and incubated overnight at 37 °C. After incubation, 100 μL of each bacterial culture was added to blood-agar plates in aliquots of 10 μL each. The plates were then incubated for 18 h at 37 °C and the presence of hemolysin was determined by the formation of a halo of lysed erythrocytes around the bacterial growth. Bacterial isolates cultured in TSB were centrifuged at 12,000 g for 15 min at 4 °C and filtered

through a Millipore 0.45 μm pore-diameter syringe filter. Clarified supernatant was tested for proteolytic activity on casein agar plates. Casein agar plates consisted of 25 mM Tris (pH 7.2), 150 mM NaCl, 0.6% casein (Sigma technical grade) and 1% TSA. Aliquots (10 μL) of culture supernatants were placed in 3 mm diameter wells cut in the casein agar and incubated at 37 °C for 18 h. The plates were overlaid with 3% acetic acid, and proteolytic activities were noted as a clear zone around the sample well. Trypsin (1 μg/mL) was used as a positive control standard. Gelatinase production was determined by API 20E and API 20NE biochemical identification kit from Biomerieux, France. Forty microliters of bacterial culture previously grown in TSB at 37 °C for 18 h (106 cell/mL) were added in triplicate to 3 mL of TSB in the presence of either 5, 1 or 0.5 mg of P. motoro venom and incubated for 18 h at 37 °C. As control, the bacterial strains were grown in the presence of TSB alone.

“The Atlantic cod (Gadus morhua) fishery has historically been very important for several countries including Canada, Norway, and Iceland. However, unpredictable and variable harvests of wild Atlantic cod resulted in all of these countries, and others (e.g. United States, Scotland), initiating cod aquaculture research and production programs to meet consumer demand for this species ( Kjesbu et al., 2006 and Bowman

et al., 2011). Early life stage mortality, potentially caused by low egg quality, is an important issue for Atlantic cod aquaculture ( Seppola RG7420 solubility dmso et al., 2009 and Avery et al., 2009 and references therein). Indeed, poor egg quality and high levels of mortality during embryogenesis are serious issues in the aquaculture of many marine fish species ( Brooks et al., 1997). In the aquaculture industry, good quality eggs are defined as having low mortality at fertilization, eyed stage, hatch, and first-feeding ( Bromage et al., 1992; reviewed by Brooks et al., 1997). Potential influences on fish egg quality and embryonic health may include over-ripening, selleck compound the bacterial colonization of eggs, exposure to pollutants and other unfavourable environmental factors, and a variety of maternal contributions to the egg including mRNAs, proteins, and lipids (for reviews see Brooks et al., 1997, Bobe and Labbé, 2010 and Swain and Nayak, 2009). Maternal transcripts (mRNAs) deposited in the egg during

oogenesis play important roles in early embryogenesis (before the “maternal-to-embryo transition”, which occurs at mid-blastula stage in fish, and is therefore referred to as the midblastula transition), whereas zygotic transcripts play a more pronounced role after this developmental landmark ( Seppola et al., 2009, Bobe and Labbé, 2010 and Drivenes et al., 2012). Nonetheless, our understanding of how the fish maternal transcriptome influences egg quality (as assessed by embryonic mortality, percent hatch, or other indicators of developmental potential) is incomplete, and of great importance to aquaculture. Functional genomics techniques have been used to identify maternal transcript expression biomarkers of fish egg quality. For example, Mommens et al.

The polymorphism is located in the promoter region and cultured human kidney cells transfected Wee1 inhibitor with the rs28366003 G/G genotype responded with lower transcription efficiency to Cd exposure compared to cells transfected with the A/A genotype. While there are a number of polymorphisms in MT1A and MT2A, the minor allele frequency of the majority is low or unknown (http://www.ncbi.nlm.nih.gov/snp/). Variation of MT1A is described by three tagging SNPs, one of them is rs11076161, carrying information about variation in a larger genomic region (http://hapmap.ncbi.nlm.nih.gov/index.html.en).

In MT2A, only rs10636 and rs28366003 have minor allele frequency above 5%, which is suitable for gene–environment interaction analysis of medium size. However, it is not yet clear if these SNPs may modify Cd metabolism

and Cd-induced excretion of low molecular weight proteins in vivo. Our aim was to elucidate how variations in MT genes affect the metabolism of Cd and Cd-induced excretion of low molecular weight proteins. Therefore, inhabitants from areas to a varying extent polluted by Cd in South-Eastern China were genotyped for SNPs in MT1A (rs11076161) and MT2A (rs10636 and rs28366003). A cross-sectional study was performed in South-Eastern China in 2006 among persons with a history of Cd exposure through contaminated rice which is the main food consumed in this region (Jin et al., 1999 and Jin et al., 2002). The subjects included lived in either a Cd-polluted http://www.selleckchem.com/products/frax597.html area near a non-ferrous metal smelter or in a control area at 40 km from the smelter. Cd levels in rice in the contaminated areas, i.e. Methamphetamine Jiaoweibao (highly polluted) were 3.7 mg Cd/kg in rice on average, in Nanbaixiang (moderately polluted) 0.5 mg Cd/kg in rice, and these levels were higher than the State Hygienic Standard (0.2 mg Cd/kg). Yantuo (control area) demonstrated 0.072 mg Cd/kg in rice on average. In 1996, the residents of the Cd-contaminated areas were asked to stop

producing rice in their own fields and to eat commercial rice from non-polluted areas (0.03 mg Cd/kg). Based on registry information available from the local authorities, the characteristics of the populations (such as age, sex distribution and birth rate) were available for the three areas (highly polluted, moderately and control area). Data from nutrition surveys performed in the period after 1960 were collected and present nutritional status was assessed by means of a targeted interview of 10 families in each area. Participants were selected based on this information to ensure that living conditions, social and economic conditions, and lifestyles were similar in all areas. Only persons born in the respective areas who had lived there and consumed locally grown rice throughout their entire lifetime (apart from the years when the local rice was banned) were included in the present study.

Não podemos esquecer, que estes critérios não foram feitos para identificar síndromes de sobreposição e, na suspeita de autoimunidade, a biopsia hepática ainda é fundamental sendo, por vezes, o melhor árbitro e guia terapêutico. Seria útil uma comparação entre os 2 sistemas de classificação na determinação que doentes necessitariam realmente de biopsia hepática e quais beneficiariam com a terapêutica imunossupressora. Para além da necessidade de uma validação em grandes estudos prospectivos dos critérios simplificados, temos ainda por esclarecer se haverá algum critério de classificação melhor para uma determinada população. Será este baixo Tofacitinib valor

de concordância obtido no artigo de Correia L. et al 15 um aviso que os critérios simplificados não serão os ideais para a nossa população? Qual o melhor score para a nossa população

“A hepatite autoimune (HAI) é uma inflamação do fígado de etiologia desconhecida1 and 2. Pensa-se que na sua fisiopatologia estejam envolvidos fatores ambientais, falência de mecanismos de imunotolerância e predisposição genética que, em conjunto, vão induzir uma resposta celular contra antigénios Linsitinib research buy hepáticos, mediada pelos linfócitos T, levando a um processo progressivo de necroinflamação e de fibrose2, 3 and 4. É uma doença relativamente rara, sendo a prevalência de 11 a 17 indivíduos por cada 100 000, com uma incidência de 1 a 2 indivíduos DNA ligase por ano por cada 100 0002. Pode surgir em ambos os sexos (embora seja mais frequente no feminino) e em todos os grupos etários e raças1, 2, 5 and 6. O diagnóstico baseia-se nas alterações histológicas, nas características clínicas e nos achados laboratoriais (aumento das globulinas

séricas e presença de um ou mais autoanticorpos característicos)1, 2, 7, 8, 9 and 10. Tem apresentação clínica variável, pelo que o seu reconhecimento pode ser difícil. Frequentemente assintomática ou com sintomas inespecíficos (fadiga, icterícia, náuseas, dor abdominal e artralgias), pode também apresentar-se como hepatite aguda grave ou como falência hepática fulminante, com necessidade de transplante hepático9, 11 and 12. Assim, deve ser suspeitada em qualquer doente com aumento das aminotransferases6. Quando não é tratada, a HAI tem mau prognóstico, com desenvolvimento de cirrose hepática em menos de 10 anos e com sobrevivência de 50% aos 5 anos5 and 6. Por outro lado, com terapêutica imunossupressora, à qual mais de 80% dos doentes responde, a maioria pode esperar sobrevivência normal e com boa qualidade de vida13 and 14. Por esse motivo, o diagnóstico e o tratamento atempados são fundamentais5 and 6.

Along the Dariven Fault, the Hutton Sandstone, the Hooray Sandstone and the Cadna-owie Formation are partially juxtaposed against aquitards. For example, along the Dariven Fault, 71% of MAPK inhibitor the entire thickness of aquifers are displaced against impermeable units on opposite sides of the fault. Hence, the Marathona Monocline and the Dariven Fault are more likely to behave as barriers to horizontal groundwater flow. Understanding the role of faults

on hydraulic connectivity between aquifers is very important for groundwater management. For example, where different aquifers are juxtaposed across a fault, this fault displacement can result in preferential pathways for hydraulic connectivity between different aquifers. Within the study area, the entire Hutton Sandstone (approximately 90 m thick) and the Hooray Sandstone interface due to vertical displacement

along the Stormhill Fault (Fig. 8). A similar situation exists at the Lochern Fault, where all the main aquifers partially interface other aquifers on the opposite side of the fault (with 50% of the entire aquifer thickness interfacing other aquifers on the down-gradient side of the fault). This suggests that there are likely to be interactions between different aquifers at the Lochern Fault and that these aquifers (i.e. the Hutton Sandstone/Adori and Hooray sandstones, Adori Sandtone/Hooray Sandstone and Hooray Inhibitor Library Sandstone/Cadna-owie Formation) may form one connected groundwater flow system. Another example where two different aquifers may be connected occurs across a fault occurs at the Tara Structure where the Cadna-owie Formation aquifer interfaces the Hutton Sandstone aquifer (Fig. 8). In this case, groundwater Progesterone flow may be continuous from the Cadna-owie Formation into the Hutton Sandstone whereas it is likely to be impeded in the overlying aquifers (on the western side of the fault). Apart from the geometry and hydraulic properties

of the aquifers, the nature of connectivity across the fault also depends on the width and permeability/mineralogy of the fault zone. However, there are no data available on the fault zone characteristics in the model domain as no exploration wells intersect any faults. Possibly the most significant barrier to groundwater flow in aquifers shown on Fig. 8 is the Maneroo Platform (e.g. on the northern side of the Hulton-Rand Structure). The general groundwater flow direction is towards the west in this area, and the most important GAB aquifers are juxtaposed against the basement (which is displaced by 740 m). This relationship causes a potential barrier to groundwater flow due to the low permeability of the basement in the lower part of the Tara Structure, which is likely to result in flow to the surface or induce inter-aquifer connectivity.

A imunorreatividade «para»

Hep-par-1 revelou-se inconclusiva. O restante parênquima hepático apresentava aspetos diagnósticos de cirrose, com depósitos de cirrose. Foram consideradas as seguintes hipóteses de diagnóstico: colangiocarcinoma, IPI-145 in vivo hepato-colangiocarcinoma, CHC esclerosante. O caso foi apresentado em reunião de grupo oncológico hepatobiliar, que propôs tratamento cirúrgico da lesão. Em março de 2009 foi realizada laparotomia exploradora e, per-operatoriamente, uma ecografia hepática, que revelou nódulos hepáticos dispersos. Foram realizadas biopsias da lesão hepática com cerca de 10 cm, dos segmentos vii e viii e de 2 outros pequenos nódulos, sem outras intervenções. No exame histológico observaram-se características sobreponíveis às identificadas na biopsia percutânea. O caso foi enviado para consulta em centro de referência internacional (Centro Médico da Universidade de Chicago, EUA), cujo relatório descreve, no exame histológico, um parênquima hepático cirrótico, infiltrado por neoplasia maligna constituída por células dispostas em ninhos e cordões, com estruturas glandulares ocasionais, apresentando as células neoplásicas citoplasma eosinofílico e ligeiramente granular.

No exame imunocitoquímico observou-se positividade das células tumorais «para» o ON 1910 CK7 e CK19 e negatividade para o Hepar-1, CD10 e glipicano 3, sugerindo-se o diagnóstico de colangiolocarcinoma, que, pelas características morfológicas, poderá corresponder à entidade recentemente descrita como colangiolocarcinoma4. A evolução clínica após a cirurgia foi desfavorável, com descompensação da insuficiência hepática e rápida progressão da doença, tendo o doente falecido um mês depois. A hemocromatose é uma anomalia hereditária da população caucasiana, na qual a incidência da expressão da doença é de um em 300-4005. O gene da hemocromatose foi identificado no braço curto do cromossoma 6 e, 80-90% dos doentes são homozigotos para a mutação C282Y6. Complicações major da HH são a cirrose e o carcinoma hepatocelular. O carcinoma primário do fígado é responsável por até 45% das mortes em doentes com HH.

O risco relativo para o desenvolvimento duma neoplasia primária do fígado em doentes com HH e cirrose é cerca Inositol oxygenase de 200 x superior ao da população em geral. A maior parte dos tumores hepáticos, na HH, corresponde ao CHC clássico. No entanto, raros casos isolados de colangiocarcinoma (CC) foram relatados. A incidência de tumores hepáticos com diferenciação colangiolar permanece por esclarecer 2. O colangiolocarcinoma (CLC) é um tumor maligno primário do fígado, que é responsável por menos de 1% de todos os cancros primários do fígado, sendo portanto muito raro4. O CLC é categorizado pela Organização Mundial de Saúde (OMS) como um subtipo de hepato-colangiocarcinoma com características de células estaminais3. Esta entidade engloba 3 subtipos: o subtipo típico de células estaminais, o subtipo de células intermédias e o subtipo de colangiolocarcinoma3.

We have studied the subjective experience of volition, rather than the objective capacity to

initiate and control voluntary action. Nevertheless, our results suggest an interesting link between subjective experience of volition and capacity for voluntary control. Voluntary control is classically thought to be unaffected in pure GTS (Ganos GSK126 datasheet et al., 2014, Ganos et al., 2013 and Jung et al., 2012), and our patients were indeed able to perform the voluntary action task successfully. However, we found a strong relation in our patients between a negative aspect of voluntary control, i.e., the capacity to suppress tics, and the capacity to experience the intentional signals preceding initiation

of voluntary action. Specifically, participants who were able to suppress their tics reported earlier experiences of volition that those who did not. Importantly, these two measures were obtained independently, in separate experimental tests – no particular instruction was given regarding tic inhibition during the voluntary action task. This result Atezolizumab suggests that the capacity to discriminate signals for volition from signals related to other involuntary movements is directly related to successful voluntary self-control. The capacity to inhibit involuntary movements could cause a stronger experience of volition, by reducing the background motor noise within which signals related to voluntary action are embedded. This would improve the landscape for perceptual learning.

However, we cannot exclude the possibility that causation might run in the opposite direction. Patients who have early experiences of volition might be better able to control voluntary suppression of other, involuntary movements that lacked this marker. Our result establishes, for the first time, an association between perception of volition, and voluntary self-control, although it cannot prove the direction of causation. Irrespective of directionality, the association between experience of volition and voluntary self-control may have important implications for Sinomenine movement disorder therapies. For example, training that focuses on perception of internal volitional signals rather than on noise related to tics could potentially increase voluntary self-control. The ability to perceive the signals associated with volition, and to discriminate them from other internal motor events, is a crucial first stage in developing the capacity for voluntary control. Humans might acquire volition using mechanisms similar to reinforcement learning of operant actions in animals (Fetz, 1969). A gradual, implicit learning process would favour motor outputs that influenced the level of a specific class of sensations, associated with drives, desires and motivations – such as reducing hunger or inducing pleasure.
