The Effects of Tyrosol and Creatine on Exercise Performance and Cognition in Healthy Adults
This study will be a randomized, double-blind, placebo-controlled trial. It will be conducted over a 8-week intervention investigating the effects of creatine (5g Creatine monohydrate); placebo control (5g resistant dextrin), and a combination group containing both creatine and tyrosol (5g creatine monohydrate + 150mg tyrosol/day). Endurance, strength, cognition, and fatigue resistance will be examined through repeated strength and endurance testing (described below). Participants who pass initial screening will be invited on-site for day one (Visit 1) of testing where the participants will proceed with a series of tests which will include the following: (1) body composition; (2) mood and cognitive testing; (3) full-body strength testing; (4) 5RM (repetition maximum) bench press, leading to multiple sets of bench press (based on the previous weight) completed to failure; (5) finally, a time to exhaustion endurance test will be conducted followed by (6) repeat cognitive testing. After the 8-week supplementation period (\~56-60 days), all original measures will be repeated as before in the same order (Visit 2). Approximately 24 hours later (Visit 3) participants will complete a questionnaire for muscle soreness remotely, and again at 48 hours post-Visit 2 (visit 4).

The Effect of Foot Massage After Open Heart Surgery on Postoperative Pain, Sleep Quality and Mood of Patients
The randomized controlled experimental study was conducted in the cardiovascular surgery clinic of Atatürk University Health Practice and Research Center between April 2021 and September 2021.The research sample consisted of 91 patients who met the research criteria. Since exclusion criteria were met in 15 patients during the research process, the study was completed with 76 patients. Descriptive Information Form, Visual Analog Scale, State-Trait Anxiety Scale, Visual Analog Sleep Scale and Hospital Anxiety and Depression Scale were used as data collection tools. All scales were applied to the patients preoperatively. According to the Postoperative Visual Analog Scale, the patients in the experimental group who stated that they had more than 4 pains were given foot massage for a total of 20 minutes, 10 minutes on each foot. After the surgery, classical foot massage was applied to the patients for 3 consecutive days, including the day they came to the service from the intensive care unit. One day after each application, the patients' pain, sleep quality and mood levels were examined. Data were collected by applying the same procedure steps without foot massage to the patients in the control group.

Genistein, Equol, Cognitive Function and Mood: Acute. (GECFAMa)
Isoflavones (ISF) are naturally occurring compounds that can provide protective benefits for certain domains of cognitive function. Studies on the prevalence of cognitive decline and cancers in the Asian diet-eating areas of the world have investigated the effects of the ISFs and how they affect our bodies and brains. Previous literature has shown that ISFs are capable of binding oestrogen receptors in our brains that provide protection in terms of antioxidation, anti-inflammatory and promoting the growth and interaction of our brain cells. Genistein is an important ISF having been shown to provide a strong protective response in our brains and other aspects of healthcare; Equol is a metabolite of ISF and is thought to provide a similar (or stronger) response than Genistein due to its receptor binding strength. Unfortunately, not everyone is capable of digesting Equol from other Isoflavones (Daidzein) and therefore supplementing this directly could provide neurological benefits at a similar level, if not stronger than, Genistein. This acute study will aim to evaluate the efficacies of two ISFs (Genistein and Equol) versus a control group, in an immediately post-prandial timeframe. SIF are "Generally Recognised As Safe" ("GRAS") molecules by the United States of America's classification regulatory commission the Federal Drug Administration as well as deemed "Safe" by the European Food Safety Authority (EFSA). Participant will be required to undertake 2 one hour-long sessions. Interventions will be taken once after the baseline task battery is completed.

Investigating the Effects of Dietary Phospholipids on Measures of Human Brain Health and Psychological Wellbeing
The aim of this study is to investigate the effects of 6- and 12-week supplementation of a bioactive whey protein concentrate drink containing dairy phospholipids on cognitive function and mood in healthy young to middle aged adults. The proposed randomised, double blind, placebo-controlled, parallel groups design methodology will assess the cognitive, mood and lifestyle effects of 40g per day of bioactive whey protein concentrate powder mixed with water and matched placebo prior to (baseline) and after -6 and 12-week supplementation. The trial will utilise the COMPASS cognitive assessment system (Northumbria University) during the laboratory visits to measure performance on the cognitive tasks and a range of mood measures between visits examining general mood, stress, depression, anxiety, sleep quality, fatigue, and physical symptoms. Additionally, dairy dietary habits will be recorded throughout to allow for any significant changes to diet to be assessed for the potential influence on the outcome variables. Participants will be asked not to make any major changes to their diet or exercise regime for the duration of the trial. This will be checked by asking the participant if there has been any significant changes at each visit. Blood samples will also be taken from a subset of participants who opt into this part of the trial to measure any changes to plasma phospholipid profiles. 220 participants will participate, aged 25-49, and self-report as in good health. Participants will be supplied with the treatment whilst visiting the research centre on testing days and will then consume treatment at home daily. Participants will record the time they take their treatment each day in a diary that will then be returned to the research team at the end of the study testing period.

THE EFFECT OF REIKI APPLIED DURING THE POSTPARTUM PERIOD ON THE QUALITY OF POSTPARTUM RECOVERY, COMFORT AND MOOD.
The postpartum period, also defined as the fourth trimester of pregnancy, encompasses the approximately 6-8 week period following childbirth, during which the organs that underwent changes during pregnancy return to their previous state. This period is of great importance in terms of protecting the health of both mother and baby, meeting their care needs, and increasing their comfort. During the postpartum period, women experience physiological, psychological, and social changes; hormonal changes, assuming parental roles, changes in family dynamics, and increased responsibilities related to infant care can lead to adjustment difficulties. This can cause problems for the mother in both her own care and infant care. In the postpartum period, mothers may experience various health problems such as pain, fatigue, sleep disturbances, infections, breastfeeding problems, hemorrhoids, constipation, urinary incontinence, depressive symptoms, and mood swings. Pain, in particular, arises due to uterine contractions, breast engorgement, nipple tenderness, and other complications, negatively affecting the mother's mobility, sleep patterns, social interaction, and quality of life. Furthermore, stress and adjustment problems experienced during the postpartum period can lead to serious psychological problems such as delayed maternal bonding, postpartum blues, postpartum depression, psychosis, and communication problems between couples. Pharmacological and non-pharmacological methods are used in the management of these problems. However, due to the negative effects that pharmacological methods may have during breastfeeding, interest in complementary and alternative medicine practices has increased. Reflexology, aromatherapy, music therapy, acupressure, and Reiki are among these methods. Reiki is an energy therapy method that aims to balance an individual's life energy and support the natural healing process, applied through touch or the placement of hands on specific points. Reiki application is reported to have positive effects on pain, stress, anxiety, sleep quality, and coping skills. Although it is one of the preferred methods for adapting to changes and reducing problems experienced in the postpartum period, studies directly examining the effects of Reiki application on postpartum recovery quality, comfort, and mood are quite limited. Due to its low cost, ease of application, and lack of side effects, Reiki is considered an important complementary care approach that can be used in the postpartum period. The aim of this study is to determine the effect of face-to-face Reiki treatment on the quality of postpartum healing, comfort level, and mood in women who have had cesarean deliveries, on days 1, 2, and 7 of the postpartum period.

Physiological and Mood Changes After Walking in Green Spaces. A Comparison of Environments.
Natural environments, and more specifically forest environments, have shown in the last decade a growing interest as a protection against the frenetic pace of life of a large part of the urban population in developed countries, where symptoms related to stress and anxiety are associated with an increasingly frequent state of sub-health. The investigators propose to perform a randomized crossover study to analyze the effects of a walk in the forest on physiological and psychological markers related to autonomic nervous system activity in healthy adult. In addition, the investigators intend to observe whether the characteristics and perceptions of the forest environment could affect the results obtained in these markers using a scale created for this purpose. Participants will be healthy adults with no history of serious physical or psychological illnesses, who will be exposed to three forest environments. Physiological markers will be measured, including heart rate variability, which will be measured with a heart rate sensor that will monitor data throughout the exposure period, and heart rate and systolic and diastolic blood pressure, which will be measured with an automated device before and after each exposure. Before and after the walk through each of the forest environments, mood will be measured using the POMS scale, and our scale will be used to measure the perceived environmental quality after exposure to each environment. In addition to the walk through the three forest environments, a control environment on an indoor treadmill will be used as a comparator, where distance, slope and walking speed will be adjusted to replicate the intensity and physical demand of the three outdoor routes. The four interventions will be organized to create three different exposure sequences. Each exposure sequence will be randomly assigned to a different group. In turn, each participant will be randomly assigned to one of the three groups, so that all participants will undergo all four interventions in a repeated measures design. Our hypothesis supports the idea that exposure to forest environments causes changes in physiological parameters and mood associated with positive regulation for health and for the autonomic nervous system in healthy adults compared to a neutral non-forest environment. As a second hypothesis, environmental characteristics as well as the perceived quality of the forest environment would be related to the magnitude of such changes associated with autonomic nervous system regulation and mood in healthy adults.
