Purpose

The purpose of this study was to explore the factors influencing post-traumatic growth in breast cancer patients during 3 years after diagnosis.

Materials and methods

Our longitudinal study involved 71 medium and high-risk breast cancer patients, who received special attention and either hypnosis or music psychological intervention while receiving the same chemotherapy protocol. The influences of the interventions, as well as the demographic (age, marital status, and educational level) and psychosocial factors (coping, post-traumatic stress, and well-being), on post-traumatic growth were explored.

Results

The results showed that over 97% of our patients experienced post-traumatic growth. It was positively associated with Quality of Life domains 3 years after diagnosis, and with Psychological Immune Competence cumulative scores after treatment and 3 years after diagnosis. Psychological Immune Competence, emotional severity of post-traumatic stress symptoms, and the social support scale of Quality of Life explained 33.9% of the variance of post-traumatic growth.

Conclusion

The results confirm that positive coping strategies, emotional severity of post-traumatic stress symptoms, and social support contribute to post-traumatic growth, and that post-traumatic growth has a weak to moderate association with quality of life.

Total phenolic content and antioxidant capacity (FRAP method) of Ginkgo biloba L. leaves and of different commercial ginkgo teas were determined and compared. Different water extracts (infusions and decoctions) were prepared varying the time of infusing, boiling, and steeping, and also aqueous ethanolic (water/ethanol 80/20 v/v) extract was made.

Total phenolic contents and FRAP values of collected ginkgo leaves were similar to those of commercial ginkgo mono teas, while these parameters were significantly higher for ginkgo teas containing ginseng or green tea. Decoction was more effective than infusion for extracting antioxidative compounds, in contradiction to suggested preparation methods by the producers. Aqueous ethanolic extracts had significantly higher total phenolic content and antioxidant capacity than water extracts. The correlation between phenolic content and FRAP values was very strong and positive for water extracts of collected leaves, while it was weak and negative for the tea products.

In the past decades many papers were published on the nutritional effect and bioactive components of edible mushrooms. The fungi are able to accumulate secondary metabolites, for example, phenolic compounds, polyketides, terpenes and steroids. In case of mushrooms the button mushrooms are preferred in the Eastern-European region. Therefore white and cream type button mushroom (Agaricus bisporus) and different A. subrufescens (syn. A. blazei) cultivars were cropped, total phenolic content and antioxidant capacity (FRAP) were measured in two years of experiments. To develop the description method of mushroom products, software-supported profile analysis was applied to characterize them. The aim of the research was to compare the sensory profiles of the samples, and to find those characteristics, they actually differ in.

The different methods of making herbal tea used in various cultures may decrease the efficiency of herbal tea, therefore the purpose of the present study was to examine the changes in antioxidant activity and metal ion concentration in aqueous extracts of “Tieguanyin Stomach Tea” obtained with different steeping times. Partial phytochemical examination, element analysis, and the determination of antioxidant properties were carried out. High Al, Cr, Mn, Ni, Pb and Ti content was observed in the tea drug. Aqueous extracts of the drug sample showed H-donor activity, reducing power and scavenging activity, depending on the steeping time and concentration. According to our findings, 5-min steeping was the least effective and redox parameters of the aqueous extracts did not change considerably between 15 and 120 min of steeping time.

Dietary intake of polyphenols and vitamins before surgery may have beneficial effect on survival of the patients. Table beet (Beta vulgaris L. var. rubra) contains bioactive agents, which have a wide range of different physiologic effects. These agents have beneficial antioxidant properties. The aim in the present study was to determine the gut protecting properties of bioactive substances of table beet in a model of ischaemic-reperfusion injury of the rat liver. Chemiluminescent intensity, H-donating ability, reducing power and free SH-group concentracion were determined by luminometry and spectrophotometry in duodenum and plasma. Lyophilized table beet increased significantly the free radical scavenging property of the plasma measured by chemiluminometry. Other antioxidant parameters of the plasma increased in rats fed table beet diet, and change in reducing power was significant. Beneficial effect of the treatment was found in changes of total scavenger capacity of the duodenum during ischaemia-reperfusion injury. H-donating ability and reducing power of the gut decreased in the table beet-fed group during ischaemia-reperfusion compared to normal group with ischaemia-reperfusion. Based on these data, it can be concluded that table beet can protect the entire body from the oxidative damage caused by ischaemia-reperfusion of the liver, but the effect of table beet treatment on gut mucosa needs further investigation.

Of the twenty table beet ( Beta vulgaris L. ssp. esculenta convar. crassa provar. conditiva ALEF.) cultivars investigated for several nutritionally important components (betaine, betanin, phenol, glucose, fructose, sucrose) formerly (Hájos et al., 2004), cultivar Ditroit having average quality parameters was chosen for in vitro animal experiments. The hyperlipidemic rat model is suitable to study the physiological effect of table beet on the metabolic alterations and the redox homeostasis in the liver. In fatty liver, as a consequence of hyperlipidemy, the redox homeostasis is strongly injured. General biologically active compounds of table beet have indirect lipid lowering effect and antioxidant properties. Therefore, the effect of lyophilised table beet powder was studied on altered lipid metabolism and redox parameters in hyperlipidemic rats. Hyperlipidemy was induced by a fat-rich diet, and both in the control group and in the hyperlipidemic group, animals were treated with the lyophilised table beet powder (2 g bwkg −1 ) added into rat chow for 10 days parallel with the feeding. Significant antioxidant activity of table beet was recorded in the hyperlipidemic liver. This phenomenon was expected because of the significant amount of betanin and the high total polyphenol content of the beet. Significant beneficial changes were also observed in the serum cholesterol level, alkaline phosphatase and alanine-aminotransferase activities, although a non-expected elevation was observed in the serum bilirubin level in hyperlipidemy. Non-specific H-donor activity was not changed, but protein related free SH-group concentration was decreased in the plasma. Serum triglyceride level was better after table beet treatment in normolipidemy, only. Change of redox-homeostasis was more favourable in the liver during the treatment. Diene conjugate content and the level of induced free radicals decreased during the table beet treatment in case of fatty liver. These changes were due to the bioactive components of the commercially available table beet. Consequently, table beet due to its specific qualities beneficially influences several metabolic pathways, therefore it can be considered as a functional food.

Purpose

The effectiveness of psychotherapeutic techniques with breast cancer patients has been extensively studied; however, there is limited information available on subjective experiences of patients. The aim of this study was to establish a category system and describe the characteristics of patients’ subjective experiences in three different intervention groups: hypnosis, music, and special attention.

Materials and methods

Content analysis of short interviews after 21 sessions of intervention was conducted to examine and compare subjective experiences in hypnosis, music, and special attention. Two types of coding system were developed: Characteristics of Involvement (CI) and Intensity of Involvement (II).

Results

Based on CI, the most dominant subjective experience of breast cancer patients was the “Pleasant Somatic Experience.” Furthermore, “Visualisation of Symbols” was the most frequent in the hypnosis intervention. Based on II, most common experience of the special attention group was coded as “low intensity.” The frequencies of “low/high intensity” experiences were different between hypnosis and music interventions. “High intensity” was more dominant in hypnosis than music intervention.

Conclusions

Both category systems may be reliable tools to examine patients’ subjective experience. Hypnosis as intervention can result in more extended subjective experiences in CI and II.

Abstract

The aim of our research was to study the water and ethanol extractable polyphenols of stinging nettle (Urtica dioica L.) harvested in different seasons and to determine their antimicrobial activity against certain human pathogenic and food spoiling bacteria and yeasts.

Our results indicate that the spring leaf extracts had higher polyphenol contents than the root one; however, close to the end of the vegetation period these values decreased considerably in both leaves and roots. Detection and quantification of the most abundant phenolic compounds in the spring extracts by HPLC revealed the occurrence of 12 different phenol carboxylic acids and flavonoids. Flavonoid compounds were more abundant than phenol carboxylic acids in the leaves; however, their proportion was equal in the case of the roots. Nettle leaf extracts had remarkable antimicrobial activity, the spring extracts were more efficient than the autumn ones. Escherichia coli and Staphylococcus aureus were sensitive to every leaf extract, while Listeria monocytogenes and Pseudomonas aeruginosa had reduced but remarkable sensitivity patterns. Among the yeasts, Candida glabrata was strongly inhibited by the aqueous leaf extracts. Most of the strains were insensitive to the root extracts, although Enterococcus faecalis was inhibited by the root and not the leaf extracts.
