Previous research has demonstrated beneficial effects of acute exposure on a range of variables. The current study set out to investigate for the first time whether extended exposure to the aroma of peppermint essential oil could provide benefits to healthy young adults. One hundred participants were randomly assigned to either wear a peppermint infused non-transdermal skin patch or a blank patch, for a period of six hours during which time they went about their normal daily routine. Cognitive and mood assessments were completed and a multivariate analysis of variance indicated a significant difference to exist between the two groups when all variables were analysed together. Further analyses on the individual variables revealed small to medium positive effects of peppermint aroma on aspects of memory and attention and feelings of subjective alertness. These findings add to a growing body of evidence that suggests aroma of peppermint essential oil may act as a positive and easy intervention delivering beneficial objective and subjective outcomes. The findings are discussed in terms of putative mechanisms that might underpin the effects with a focus on possible pharmacological influences.展开更多

Twenty healthy adults were randomly allocated to consume either 330 ml of No. 1 Rosemary water or plain carbonated water. They then completed a series of subjective measures and cognitive tasks including a fifteen-minute session on a stress inducing multi-tasking framework, followed by a second completion of the subjective measures. Heart rate and blood pressure were monitored throughout the procedure. Given the pilot nature of the study, analysis of the data eschewed significance testing for the calculation of Cohen’s d measure of effect sizes. These revealed a number of small enhancement effects on cognition, consistent with those found previously for the inhalation of the aroma of Rosemary essential oil, and oral administration of dried herb. Of particular interest here are the reduced subjective evaluations of stress, and the blunted physiological reactivity noted for heart rate and blood pressure, which represent novel findings in this area. Taken together the data suggest further investigation of this product is warranted with regard to its potential beneficial properties.展开更多

This study aimed to investigate life balance of mothers of children with Cerebral palsy (MCCPs) based on the Life Balance Model. Method: Fifty MCCPs aged 3 to 9 years with sample convenient method participated in this descriptive and cross-sectional study. The Severity of cerebral palsy was determined by Gross Motor Function Classification System (GMFCS) and Manual Ability Classification System (MACS) and the life balance of mothers was evaluated by Persian version of the LBI (P_LBI). The collected data were evaluated and analyzed using SPSS software. Results: The total mean score of LBI and its subscales showed that there is no balanced or very balanced life in mothers and they could be categorized to unbalanced (n = 21) and very unbalanced (n = 29). The total mean score of LBI was 1.46. χ2 test revealed statistically significant difference between two categories (unbalanced and very unbalanced) of mothers regarding GMFCS level (p = 0.009). Also, the total mean score of LBI and its subscales showed no significant difference between two categories (unbalanced and very unbalanced) regarding mother job and age and child age (p > 0.05) but it has significant difference regarding mother education (p = 0.009). Evaluation of the results of LBI and its different subscales indicated that the life balance at balanced or very balanced levels was not observed in any of the studied mothers, and they could be categorized in 2 groups of unbalanced (21 mothers ) and very unbalanced (29 mothers) (Table 2). Discussion: Based on the result of this study, mothers of Cerebral Palsy do not experience balanced life and this feeling of unbalance is related to the level of their child’s disability. Thus, it is necessary to consider this fact in family-centered evaluations and Occupational therapy interventions.展开更多

They can look as if singly or in clusters, and they often cease to grow after menopause. Fibroids can be classified as intramural, sub serosal, pedunculated, or submucosal based on where they are positioned in the uterus. Although fibroids are benign, they can grow quickly and cause a range of symptoms, such as pelvic pressure, heavy menstrual flow, and infertility. As a result, fibroids are a main reason behind hysterectomy surgeries. The majority of cases of breast cancer are ductal and lobular cancers, making it the second utmost common cancer in women international. Gene mutations like those in BRCA1 or BRCA2 knowingly raise the risk of breast and other cancers, typically with an earlier cancer onset. Cancer risk is influenced by a complex interplay of genetic abnormalities, environmental factors, and lifestyle selections. Further research into these relations is domineering. Although they are common in uterine leiomyomas, especially multiple leiomyomas, MED12 mutations do not significantly correlate with tumor size. These mutations have also been noticed in smooth muscle tumors and leiomyosarcomas, two other types of uterine cancer. The identification of MED12 mutations as the sole genetic abnormality originates in leiomyomas raises the opportunity of a role in the genesis of cancer. 10% - 15% of women who are of reproductive age have endometriosis, which grants serious difficulties because of its chronic nature and range of clinical symptoms. Even after effective surgeries, issues reoccur often, adding to the enormous financial burden. The effects of MED12 mutations have been experiential in recent studies examining the molecular causes of endometriosis-associated infertility, which have shown anomalies in cellular connections and signaling cascades. Computational techniques were used in this study to investigate LifeGreenTM’s potential to prevent uterine fibroids and breast cancer. The efficacy of LifeGreenTM as a preventive measure or a treatment for common gynecological matters was examined and modeled. We investigated the mechanisms underlying LifeGreenTM’s benefits in the treatment of uterine fibroids and breast cancer using computational techniques. Our research contributes to our understanding of its potential therapeutic benefits for women’s health.展开更多

Evaluation of the results of LBI and its different subscales indicated that the life balance at balanced or very balanced levels was not observed in any of the studied mothers, and they could be categorized in 2 groups of unbalanced (21 mothers ) and very unbalanced (29 mothers) (Table 2). Discussion: Based on the result of this study, mothers of Cerebral Palsy do not experience balanced life and this feeling of unbalance is related to the level of their child’s disability. Thus, it is necessary to consider this fact in family-centered evaluations and Occupational therapy interventions.
文摘Aim: To examine the experiences of health care professional (HCP)-patient interactions in Multiple Sclerosis (MS), identifying factors that can influence these interactions. Methods: A three-stage systematic review and thematic synthesis of qualitative and quantitative research was undertaken. Stage 1: the systematic literature search;Stage 2: methodological appraisal of the qualitative papers;Stage 3: thematic synthesis of all qualitative papers and the integration of quantitative findings into the synthesis. Results: Forty-nine qualitative studies were identified. This included 1014 individuals with MS (244 male, 755 female and 15 unknown) and 106 carers and 86 HCPs. Seventeen quantitative studies were identified which included 7680 (2008 male, 5812 females, and 40 unknown) participants as well as 224 carers. Two themes are discussed: 1) The expectations, experiences and perceptions of interactions with HCPs, and 2) The factors that influenced interactions and relationships. Discussion: There is need for improvement in the content and provision of information to patients with MS from HCPs. Specific strategies are suggested and implications for patients and health care providers are considered.
文摘Fibroids, also called leiomyomas or myomas, are communal tumors of the muscle or uterine wall that affect about 20% of females who are of reproductive age. They can look as if singly or in clusters, and they often cease to grow after menopause. Fibroids can be classified as intramural, sub serosal, pedunculated, or submucosal based on where they are positioned in the uterus. Although fibroids are benign, they can grow quickly and cause a range of symptoms, such as pelvic pressure, heavy menstrual flow, and infertility. As a result, fibroids are a main reason behind hysterectomy surgeries. The majority of cases of breast cancer are ductal and lobular cancers, making it the second utmost common cancer in women international. Gene mutations like those in BRCA1 or BRCA2 knowingly raise the risk of breast and other cancers, typically with an earlier cancer onset. Cancer risk is influenced by a complex interplay of genetic abnormalities, environmental factors, and lifestyle selections. Further research into these relations is domineering. Although they are common in uterine leiomyomas, especially multiple leiomyomas, MED12 mutations do not significantly correlate with tumor size. These mutations have also been noticed in smooth muscle tumors and leiomyosarcomas, two other types of uterine cancer. The identification of MED12 mutations as the sole genetic abnormality originates in leiomyomas raises the opportunity of a role in the genesis of cancer. 10% - 15% of women who are of reproductive age have endometriosis, which grants serious difficulties because of its chronic nature and range of clinical symptoms. Even after effective surgeries, issues reoccur often, adding to the enormous financial burden. The effects of MED12 mutations have been experiential in recent studies examining the molecular causes of endometriosis-associated infertility, which have shown anomalies in cellular connections and signaling cascades. Computational techniques were used in this study to investigate LifeGreenTM’s potential to prevent uterine fibroids and breast cancer. The efficacy of LifeGreenTM as a preventive measure or a treatment for common gynecological matters was examined and modeled. We investigated the mechanisms underlying LifeGreenTM’s benefits in the treatment of uterine fibroids and breast cancer using computational techniques. Our research contributes to our understanding of its potential therapeutic benefits for women’s health.

文摘Myelin is the protective sheath surrounding nerve fibers, and its damage(demyelination) occurs in many central nervous system(CNS) diseases, including multiple sclerosis(MS), traumatic injury, neurodegenerative diseases such as Alzheimer's disease, and mental disorders such as schizophrenia(Barateiro et al., 2016). Repair of damaged myelin sheaths(remyelination) often fails in MS, leading to neuronal loss and irreversible functional deficits.

文摘Low-density lipoprotein receptor-related protein 1(LRP1)is a multifunctional endocytic receptor whose dysfunction is linked to developmental dysplasia of the hip,osteoporosis and osteoarthritis.Our work addresses the critical question of how these skeletal pathologies emerge.Here,we show the abundant expression of LRP1 in skeletal progenitor cells at mouse embryonic stage E10.5 and onwards,especially in the perichondrium,the stem cell layer surrounding developing limbs essential for bone formation.Lrp1 deficiency in these stem cells causes joint fusion,malformation of cartilage/bone template and markedly delayed or lack of primary ossification.
文摘Hypnosis is a promising tool in the management of various conditions,such as anxiety and chronic pain.Preliminary studies have shown that hypnosis can directly affect the cardiovascular system,as it increases parasympathetic activation and reduces sympathetic activity.However,the literature related to the effects of hypnosis on cardiovascular health is scarce,mainly due to misconceptions about hypnosis among researchers and medical professionals.This opinion paper examines the role that hypnosis may play in cardiovascular health,highlighting the physiological mechanisms behind it.The evidence suggests that hypnosis has both direct(e.g.,changes in the activity of the autonomic nervous system)and indirect(e.g.,changes in healthy behaviours)effects on the cardiovascular system;however,further studies are needed to properly define its mechanisms of action and its applicability in improving cardiovascular health.Thus,this opinion paper advocates the adoption of the term“hypno-cardiac physiology”to identify a new research area that gathers experts from neuroscience and cardiovascular science with the joint aim of seeking further understanding of the effects of hypnosis on the cardiovascular system.The adoption of a dedicated term to identify the study of the cardiovascular response to hypnosis will encourage its implementation in cardiovascular health interventions,promoting awareness of its effects among the public and the healthcare community,and promoting the formation of dedicated multidisciplinary research groups and dedicated educational training for healthcare professional interested in its applications.

文摘Liver diseases,particularly acute alcoholic liver injury(AALI),drug-induced liver injury(DILI),and hepatocellular carcinoma(HCC),have become global public health issues.Glutathione(GSH),as an important antioxidant,plays a crucial role in the liver,and its changes are closely associated with liver injury and the development of liver cancer.Therefore,accurately monitoring GSH variations is critical for understanding liver injury mechanisms,early diagnosis,and treatment evaluation.However,traditional detection methods suffer from insufficient sensitivity and selectivity.To address these challenges,we developed an innovative DR-Au^(3+)/DR-Pd^(2+)complex probe that can rapidly and sensitively detect GSH through near-infrared(NIR)fluorescence changes.This probe,with the optimal excitation and emission wavelengths of the probe both located in the NIR region,exhibits excellent selectivity and liver-targeting ability,overcoming the imprecision localization problems of traditional methods.In the AALI and DILI models,the optimized DR-Au^(3+)probe enables real-time monitoring of GSH level fluctuations,providing a powerful tool for early diagnosis of liver injury and dynamic evaluation of therapeutic efficacy.In the DILI and HCC models,the DR-Au^(3+)probe enables visualization and quantitative monitoring of the ferroptosis process,offering new perspectives and approaches for targeted therapy research.The DR-Au^(3+)probe we developed pioneers innovative strategies for establishing accurate diagnostic protocols and individualized therapeutic regimens in hepatic injury and hepatocellular carcinoma management.
