Altered States of Consciousness during Exercise, Active-Alert Hypnosis, and Everyday Waking State.

This retrospective study was a nonrandomized comparison of exercisers' (runners and participants of a spinning class) states of consciousness with subjects of active-alert hypnosis (AAH) and students in a class (control). Three hundred and seventy-five participants completed the Phenomenology of Consciousness Inventory (PCI). Runners, spinners, and participants of AAH scored higher on the altered experience and altered state of awareness dimensions of the PCI than the control group. Runners scored higher than participants of AAH and the control condition on the rationality dimension, and spinners scored higher than participants in the AAH condition. The AAH group scored lowest on the self-awareness dimension. On the volitional control dimension, the spinning and control groups scored significantly higher than the runner and AAH groups. The results suggest that exercise may lead to states of consciousness similar to AAH and thus increase responsiveness to a coach's training suggestions.

The Characteristics and Prevalence of Dream Bizarreness, Inter-individual Differences and Their Relation to Quality of Life.

OBJECTIVE: As existing findings are inconclusive, this paper aims to provide a thorough analysis of the bizarreness of everyday dreams and to explore its relations to the emotional quality of dreams and the dreamers' quality of life. METHOD: 61 women's two week long dream journal (502 dreams) were analyzed using two different kinds of scales in order to capture the bizarre qualities of the reports. The emotional qualities of the dreams were also classified. At the end of the dream log participants filled in the WHOQOL-100 questionnaire to evaluate the different aspects of their quality of life. We examined the frequency and distribution of the distinct forms of distortions in every day dreams by using descriptive statistics. We carried out one-way analysis of variance to analyze the connection between the emotional tone of dreams and their bizarreness. To explore how the inter-individual differences in the qualities of dreams relate to the dreamers quality of life, Spearman correlation and Linear regression were calculated. RESULTS: According to our findings, although most home reported dreams contain some bizarre elements, they are rarely extremely unrealistic, and there is also a considerable amount of totally mundane dreams. The distortions are not randomly distributed but are mostly related to those parts of the reports which are created during the process of narrative formation. Our findings implicate substantial individual differences regarding the bizarreness and emotional tone of everyday dreams, and both of them correlate with some aspects of the subject's quality of life. CONCLUSIONS: Those theories should be favored, which can accommodate both unrealistic and totally mundane reports, and can account for the interpersonal differences in this quality of dreams.

Biscuits Enriched with Monofloral Bee Pollens: Nutritional Properties, Techno-Functional Parameters, Sensory Profile, and Consumer Preference.

Bee pollens are potential functional food ingredients as they contain essential nutrients and a wide range of bioactive compounds. The aim of this study was to investigate the effects of enrichment with monofloral bee pollens on the nutritional properties, techno-functional parameters, sensory profile, and consumer preference of biscuits. Biscuits were prepared according to the AACC-approved method by substituting wheat flour with pollens of rapeseed (Brassica napus L.), phacelia (Phacelia tanacetifolia Benth.) and sunflower (Helianthus annuus L.) at 2%, 5% and 10% levels. The macronutrient composition of the biscuits was determined: crude protein content (Kjeldahl method), crude fat content (Soxhlet extraction), ash content (carbonization), moisture content (drying), carbohydrate content (formula). Their total phenolic content (TPC) and in vitro antioxidant capacity (FRAP, TEAC, DPPH) were determined spectrophotometrically. The colour of the biscuits was measured using a tristimulus-based instrument, and their texture was characterized by using a texture analyser. Sensory profile of biscuits was determined by qualitative descriptive analysis (QDA). The consumer acceptance and purchase intention of the biscuits were also evaluated, based on the responses of 100 consumers. Additionally, an external preference map was created to illustrate the relationship between consumer preference and the sensory profile of the biscuits, and penalty analysis was conducted to identify directions for product development. Phacelia pollen appeared to be the most effective for improving the nutritional quality of biscuits. The addition of phacelia pollen at the 10% substitution level increased the protein content and TPC of the control biscuit by 21% and 145%, respectively. Significant changes (p < 0.05) were also observed regarding the colour and texture of biscuits. The results of the QDA revealed that biscuits containing pollens of different botanical sources have heterogeneous sensory attributes. The biscuit containing sunflower pollen at the 2% substitution level was preferred the most (overall liking = 6.9 ± 1.6), and purchase intentions were also the highest for this product. Based on the results of the present study, it is recommended to use sunflower pollen for developing pollen-enriched foods in the future.

Application of Near-Infrared Spectroscopy to Investigate Some Endogenic Properties of Pleurotus ostreatus Cultivars.

Fourteen different Pleurotus ostreatus cultivars (Po_1-Po_14) were tested for free amino acid content (fAA), total polyphenol content (TPC), and antioxidant capacity (Ferric Reducing Ability of Plasma-FRAP) to select the cultivars with the most favorable traits. Automatic amino acid analyzer (fAA) and spectrophotometric assay (TPC, FRAP) results as well as Fourier-transform near infrared (FT-NIR) spectra were evaluated with different chemometric methods (Kruskal-Wallis test, Principal Component Analysis-PCA, Linear Discriminant Analysis-LDA). Based on total free amino acid concentrations and FRAP values, the Po_2 cultivar was found to be the most favorable. Types Po_3, Po_8, Po_10 and Po_12 were separated using PCA. Based on the spectral profile, they may contain polyphenols and reducing compounds of different qualities. LDA classification that was based on the concentrations of all free amino acids, cysteine, and proline of the cultivars was performed with an accuracy of over 90%. LDA classification that was based on the TPC and FRAP values was performed with an accuracy of over 83%.

RECALLED PARENTAL REARING STYLE AND DIMENSIONS OF HYPNOTIC RESPONSE.

So far, only a few studies have investigated how memories of parental rearing style are associated with hypnotic response, and these were either qualitative or confined to the behavioral aspect of hypnotizability. The present study aims to employ standardized, quantitative measures to investigate the associations between recalled parental rearing style and the behavioral, phenomenological, and emotional dimensions of hypnotic response. Two samples of healthy adult subjects (N = 438) completed a questionnaire on their parents' behavior and participated in a standard group hypnosis session in which their hypnotizability score, hypnotic experiences, and archaic involvement were assessed. Memories of cold and punishing parental behavior were associated with negative experiences related to the hypnotic state and negative emotions toward the hypnotist. The authors conclude that assessing parental behavior may be important in planning hypnotherapeutic interventions.

Active-Alert Hypnosis: History, Research, and Applications.

After a brief review of the history of the idea of an activity-increasing hypnotic induction procedure with eyes open and pedaling a bicycle ergometer, the features of active-alert hypnotic induction are summarized. Results of research conducted on healthy volunteers revealed the behavioral, experiential, physiological, and interactional characteristics of the induced altered state of consciousness (ASC), showing both similarities and differences between traditional and active-alert hypnosis. A short description of the application of the method is followed by two brief case studies.

Total Polyphenol Content and Antioxidant Capacity of Rosehips of Some Rosa Species.

Background: Rosehips, the fruits of Rosa species, are well known for their various health benefits like strengthening the immune system and treating digestive disorders. Antioxidant, anti-inflammatory, and cell regenerative effects are also among their health enhancing impacts. Rosehips are rich in compounds having antioxidant properties, like vitamin C, carotenoids, and phenolics. Methods: Total polyphenol content (Folin-Ciocalteu's method), and in vitro total antioxidant capacity (ferric-reducing ability of plasma, FRAP) in rosehips of four Rosa species (R. canina, R. gallica, R. rugosa, R. spinosissima) were determined and compared. Ripe fruits were harvested at two locations. Water and ethanolic extracts of dried fruit flesh were analyzed. Results:R. spinosissima had the highest total phenolic content and antioxidant capacity, significantly higher than the other investigated Rosa species. Both parameters were reported in decreasing order for R. spinosissima > R. canina > R. rugosa > R. gallica. Ethanolic extracts of rosehips showed higher phenolic content and antioxidant activity than water extracts. Antioxidant properties were influenced by the growing site of Rosa species. Conclusions: This study indicates that R. spinosissima exhibited the greatest phenolic and antioxidant content, and therefore can be used as a reliable source of natural antioxidants, and serve as a suitable species for further plant breeding activities. Furthermore, investigations of various Rosa species for their antioxidant properties may draw more attention to their potential as functional foods.

[Health effects of sour cherries with unique polyphenolic composition in their fruits]. / A különleges és egyedi polifenol-összetételu meggy egészségi hatásai.

Health effects of fruit consumption are confirmed by many studies. Such effects are attributed to the polyphenolic compounds accumulating in fruit skin and mesocarp tissues. They contribute to the regulation on transcriptional, post-transcriptional and epigenetic levels. Since people consume much less fruits than the recommended quantities, a new approach includes the promotion of super fruits that are extremely rich sources of specific health compounds. A comparative analysis of Hungarian stone fruit cultivars detected a huge variability in fruit in vitro antioxidant capacity and total polyphenolic content. Two outstanding sour cherry cultivars ('Pipacs 1' and 'Fanal') were identified to accumulate elevated levels of polyphenolic compounds in their fruits. Sour cherries with different polyphenolic compositions were tested against alimentary induced hyperlipidemia using male Wistar rat model. Consumption of cherry fruit had different consequences for different cultivars: consumption of 'Pipacs 1' and 'Fanal' fruits resulted in 30% lower total cholesterol levels in the sera of hyperlipidemic animals after only 10 days of treatment. However, the consumption of 'Újfehértói fürtös' fruit has not induced significant alterations in the same parameter. Other lipid parameters also reflected the short-term beneficial effects of 'Pipacs 1' and 'Fanal' fruits. We suggest that not only some tropical and berry fruits might be considered as super fruits but certain genotypes of stone fruits as well. These have indeed marked physiological effects. Since 'Pipacs 1' and 'Fanal' are rich sources of colourless polyphenolics (e.g., phenolic acids and isoflavonoids) and anthocyanins, respectively, the protective effects associated with their consumption can be attributed to different polyphenolic compounds.

Production of Hypoallergenic Antibacterial Peptides from Defatted Soybean Meal in Membrane Bioreactor: A Bioprocess Engineering Study with Comprehensive Product Characterization.

Hypoallergenic antibacterial low-molecular-mass peptides were produced from defatted soybean meal in a membrane bioreactor. In the first step, soybean meal proteins were digested with trypsin in the bioreactor, operated in batch mode. For the tryptic digestion of soybean meal protein, optimum initial soybean meal concentration of 75 g/L, temperature of 40 °C and pH=9.0 were determined. After enzymatic digestion, low-molecular-mass peptides were purified with cross-flow flat sheet membrane (pore size 100 µm) and then with tubular ceramic ultrafiltration membrane (molecular mass cut-off 5 kDa). Effects of transmembrane pressure and the use of a static turbulence promoter to reduce the concentration polarization near the ultrafiltration membrane surface were examined and their positive effects were proven. For the filtration with ultrafiltration membrane, transmembrane pressure of 3·105 Pa with 3-stage discontinuous diafiltration was found optimal. The molecular mass distribution of purified peptides using ultrafiltration membrane was determined by a liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry setup. More than 96% of the peptides (calculated as relative frequency) from the ultrafiltration membrane permeate had the molecular mass M≤1.7 kDa and the highest molecular mass was found to be 3.1 kDa. The decrease of allergenic property due to the tryptic digestion and membrane filtration was determined by an enzyme-linked immunosorbent assay and it was found to exceed 99.9%. It was also found that the peptides purified in the ultrafiltration membrane promoted the growth of Pediococcus acidilactici HA6111-2 and they possessed antibacterial activity against Bacillus cereus.

New directions in hypnosis research: strategies for advancing the cognitive and clinical neuroscience of hypnosis.

This article summarizes key advances in hypnosis research during the past two decades, including (i) clinical research supporting the efficacy of hypnosis for managing a number of clinical symptoms and conditions, (ii) research supporting the role of various divisions in the anterior cingulate and prefrontal cortices in hypnotic responding, and (iii) an emerging finding that high hypnotic suggestibility is associated with atypical brain connectivity profiles. Key recommendations for a research agenda for the next decade include the recommendations that (i) laboratory hypnosis researchers should strongly consider how they assess hypnotic suggestibility in their studies, (ii) inclusion of study participants who score in the middle range of hypnotic suggestibility, and (iii) use of expanding research designs that more clearly delineate the roles of inductions and specific suggestions. Finally, we make two specific suggestions for helping to move the field forward including (i) the use of data sharing and (ii) redirecting resources away from contrasting state and nonstate positions toward studying (a) the efficacy of hypnotic treatments for clinical conditions influenced by central nervous system processes and (b) the neurophysiological underpinnings of hypnotic phenomena. As we learn more about the neurophysiological mechanisms underlying hypnosis and suggestion, we will strengthen our knowledge of both basic brain functions and a host of different psychological functions.

Dopaminergic and Serotonergic Genotypes and the Subjective Experiences of Hypnosis.

Hypnotizability is related to the Val158Met polymorphism of the COMT gene. The authors' aim was to find associations between candidate genes and subjective dimensions of hypnosis; 136 subjects participated in hypnosis and noninvasive DNA sampling. The phenomenological dimensions were tapped by the Archaic Involvement Measure (AIM), the Phenomenology of Consciousness Inventory (PCI), and the Dyadic Interactional Harmony Questionnaire (DIH). The main results were that the "Need of dependence" subscale of AIM was associated with the COMT genotypes. The GG subgroup showed higher scores, whereas AA had below average scores on the majority of the subjective measures. An association between the 5-HTTLPR polymorphism and the intimacy scores on the DIH was also evident. The effects are discussed in the social-psychobiological model of hypnosis.

Antihyperlipidemic Effects of Sour Cherries Characterized by Different In Vitro Antioxidant Power and Polyphenolic Composition.

The aims of the present study were to clarify in vivo effects of three sour cherry cultivars characterized by different polyphenolic composition in hyperlipidemic animals in a short term experiment. The three different sour cherry cultivars were chosen based on their total in vitro antioxidant capacity, total polyphenolic, monomeric anthocyanin and flavonoid content. Male Wistar rats were divided randomly into eight groups: rats kept on normal diet (control) and normal diet supplied with sour cherry powder of one of the three cultivars; others were kept on fat-rich diet and fat-rich diet supplied with sour cherry powder prepared from one of the three cultivars. The treatment lasted 10 days. Lyophilized sour cherry administered in the diet decreased both total cholesterol and LDL cholesterol levels, and increased the HDL cholesterol concentration in sera of hyperlipidemic animals. Significant differences were found in the efficacy of different sour cherry cultivars in case of hyperlipidemia. Sour cherries characterized by higher polyphenol content seem to have a more pronounced effect on serum cholesterol levels. Our results suggest that besides anthocyanins, colourless polyphenols also have lipid lowering effect.

Hungarian norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A.

Hungarian norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) are presented. The Hungarian translation of the HGSHS:A was administered under standard conditions to 434 participants (190 males, 244 females) of several professions. In addition to the traditional self-scoring, hypnotic behavior was also recorded by trained observers. Female participants proved to be more hypnotizable than males and so were psychology students and professionals as compared to nonpsychologists. Hypnotizability varied across different group sizes. The normative data-including means, standard deviations, and indicators of reliability-are comparable with previously published results. The authors conclude that measuring observer-scores increases the ecological validity of the scale. The Hungarian version of the HGSHS:A seems to be a reliable and valid measure of hypnotizability.

Differences in antioxidant properties of ginkgo leaves collected from male and female trees.

Total phenolic content and antioxidant capacity (FRAP method) of Ginkgo biloba L. leaves collected from male and female trees were determined and compared. Different water and aqueous ethanolic (water/ethanol 80/20, V/V) extracts were prepared by varying the time of infusing, boiling and steeping in order to determine the effect of the extraction method on the above parameters. Antioxidant activity and phenolic content of ginkgo leaf extracts correlated well with significant correlation coefficients. Slopes of linear regression lines were not statistically different for either sex.

Genistein isoflavone glycoconjugates in sour cherry (Prunus cerasus L.) cultivars.

The isoflavone genistein on the contrary to its well-established health-beneficial effects is not a major component of the Western diet, since soy consumption, considered as the main dietary source of genistein, in these populations is low. Genistein compounds in twelve commercial sour cherry (Prunus cerasus L.) cultivars grown in Hungary were studied. High performance liquid chromatography coupled to electrospray ionisation quadrupole/time-of-flight mass spectrometry (HPLC-ESI-qToF-MS) was used for screening and confirmatory analyses. Genistin and genistein were found in 'Pipacs1', 'Kántorjánosi', 'Debreceni botermo' and 'Éva', which are native cultivars to Hungary. Genistein content of the latter three were in the range of 0.4-0.6, while in 'Pipacs1' in total 4.4 mg genistein compounds were measured expressed as aglycone equivalents per 100g of fresh fruit flesh. These cultivars may play important role as complementary genistein sources in the Western diet. Especially 'Pipacs 1', may be best utilised in functional food products.

A comparative assessment of antioxidant properties, total phenolic content of einkorn, wheat, barley and their malts.

Two einkorn wheat, one barley, three optional winter cultivation wheat and five winter cultivation wheat samples harvested in Hungary in 2011, and their malts were evaluated for their DPPH radical and ABTS radical cation scavenging activity, ferric reduction capacity (FRAP) and total phenolic content (TPC). All einkorn and barley samples exhibited significant antioxidant activities determined by DPPH and ABTS radical scavenging activities. The einkorn samples show higher polyphenol content than the other wheat samples. In all cases the barley sample had the highest antioxidant potential and polyphenol content. The einkorn malts had high DPPH and ABTS radical cation scavenging activities, but the phenolic content was lower against wheat samples. There was significant difference between the antioxidant potential of optional and winter cultivation wheat samples except on ABTS scavenging activities. Einkorn wheat is potentially a new raw material to produce organic beer that might have beneficial effects with its increased antioxidant potential.

Coherences of instrumental and sensory characteristics: case study on cherry tomatoes.

The aim of this study was to investigate 6 cherry tomato varieties in terms of morphological, instrumental, and sensory attributes. Hungarian cherry tomato landraces have not been investigated in comparison with new commercial varieties for these traits. Parameters investigated were water-soluble antioxidant capacity (FRAP, DPPH, and TEAC), and total polyphenol, vitamin C, ß-carotene, lycopene, total soluble solids, and acid contents. Colorimetric measurements as well as sensory analyses were conducted. It was concluded that varied antioxidant assays should be used in parallel to overcome the selectivity of any 1 method. Total phenolic content significantly contributed to results of antioxidant assays for the investigated varieties. The sensory profiles of the 6 cherry tomato varieties have been created. The differences between the products based on the 18 attributes were analyzed by Tukey post hoc test. The biplot of the principal component analysis showed that the sensory panel could discriminate the samples along the principal components. No correlation was found between colorimetric data a* and b* measured from pulp and lycopene, but a negative connection of ß-carotene and hue was noted. Total polyphenol content showed correlations with colorimetric results, except for b*. The influence of tomato skin color on color perception is significant as in the present study instrumental data measured from pulp did not match that of the panelists evaluating intact fruit. Instrumental results of sugar content were supported by the ratings of the sensory panel.

The influence of time and gender on hungarian hypnotizability scores.

In a between-lab study, a constant and steady shift was found in hypnotizability scores measured with standard scales. To investigate a time effect in a Hungarian (within-lab) sample, 613 subjects' scores on Stanford Hypnotic Susceptibility Scale, Forms A and B, 1898 subjects' self-scores, and 1713 subjects' observer-scores on the Harvard Group Scale of Hypnotic Susceptibility were analyzed. From the 1970s to 2010, a significant increase was observed in the SHSS:A and B scores of female subjects and the HGSHS:A scores of both genders. Females proved to be significantly more hypnotizable than males in a group setting but not in an individual context. Time and gender did not interact. The possible reasons for these effects on hypnotizability and the role of the testing context are discussed.

Phenomenological aspects of hypnotic interactions: the effect of kinship.

This study analyzes the relationship of various measures of hypnosis as a function of kinship. Subjects with varying degrees of kinship (mono- and dizygotic twins, siblings, and parent-child pairs) participated. The Stanford Hypnotic Susceptibility Scale, Form A (SHSS:A), as well as other measures-including the Dyadic Interactional Harmony (DIH) and the Phenomenology of Consciousness Inventory (PCI)-were used with both subjects and hypnosis practitioners. Findings indicated that the phenomenological experience of hypnosis is not determined genetically. The subjects apparently evaluated the session as related to the degree of kinship. MZ twins-on the basis of reactive interactional pattern-evaluate the hypnotic interaction similarly. This was not true for SHSS:A scores or the phenomenological aspects of the state (PCI). These findings were interpreted within the sociopsychobiological model of hypnosis.

The effects of cocoa supplementation, caloric restriction, and regular exercise, on oxidative stress markers of brain and memory in the rat model.

The effects of treadmill running (8 weeks, 5 times/week, 1h/day at 27 m/min), caloric restriction, and cocoa supplementation on brain function and oxidative stress markers were tested. The Morris maze test was used to appraise rat memory. Regular exercise significantly improved spatial learning performance. The level of oxidative stress was measured by the concentration of carbonylated proteins. The free radical concentration increased in brain of the training groups but not the controls. The content of reactive carbonyl derivates did not change with exercise, suggesting that the increased production of reactive oxygen species (ROS) were well tolerated in this experimental model. Caloric restriction (CR) decreased the accumulation of free radicals in the frontal lobe. The protein content of brain-derived neutrophic factors (BDNFs) was evaluated and changes did not occur either with exercise or cocoa supplementation treatments. These data did not show significant effects of the administration of cocoa (2% w/w) on the concentration of ROS, BDNF or on spatial memory. Conversely, exercise and CR can play a role in ROS generation and brain function.
