Abstract
Wearable sleep-tracking technology is of growing use in the sleep and circadian fields, including for applications across other disciplines, inclusive of a variety of disease states. Patients increasingly present sleep data derived from their wearable devices to their providers and the ever-increasing availability of commercial devices and new-generation research/clinical tools has led to the wide adoption of wearables in research, which has become even more relevant given the discontinuation of the Philips Respironics Actiwatch. Standards for evaluating the performance of wearable sleep-tracking devices have been introduced and the available evidence suggests that consumer-grade devices exceed the performance of traditional actigraphy in assessing sleep as defined by polysomnogram. However, clear limitations exist, for example, the misclassification of wakefulness during the sleep period, problems with sleep tracking outside of the main sleep bout or nighttime period, artifacts, and unclear translation of performance to individuals with certain characteristics or comorbidities. This is of particular relevance when person-specific factors (like skin color or obesity) negatively impact sensor performance with the potential downstream impact of augmenting already existing healthcare disparities. However, wearable sleep-tracking technology holds great promise for our field, given features distinct from traditional actigraphy such as measurement of autonomic parameters, estimation of circadian features, and the potential to integrate other self-reported, objective, and passively recorded health indicators. Scientists face numerous decision points and barriers when incorporating traditional actigraphy, consumer-grade multi-sensor devices, or contemporary research/clinical-grade sleep trackers into their research. Considerations include wearable device capabilities and performance, target population and goals of the study, wearable device outputs and availability of raw and aggregate data, and data extraction, processing, and analysis. Given the difficulties in the implementation and utilization of wearable sleep-tracking technology in real-world research and clinical settings, the following State of the Science review requested by the Sleep Research Society aims to address the following questions. What data can wearable sleep-tracking devices provide? How accurate are these data? What should be taken into account when incorporating wearable sleep-tracking devices into research? These outstanding questions and surrounding considerations motivated this work, outlining practical recommendations for using wearable technology in sleep and circadian research.

Abstract
OBJECTIVE Women's increasing workforce participation necessitates understanding unique life phases like menopause for enhanced workplace inclusivity. This research investigates the challenges and needs of peri-menopausal women in work settings, using the Job Demands-Resources model as a foundation. METHODS A cross-sectional survey was administered to 351 working women aged 40 to 65 years in the United States. Hierarchical multiple regression models were employed to assess the relationship between the severity of menopausal symptoms, emotional exhaustion, work engagement, and turnover intentions. RESULTS Most of the respondents reported moderate (38.46%) to severe (35.9%) menopausal symptoms. Notably, 54% of the women were caregivers for children or adults. About 77.7% of participants reported work-related challenges due to menopause, with a perceived reduction in productivity (56.8%) being the most common issue. The severity of menopausal symptoms was found to significantly predict more emotional exhaustion ( P < 0.001), less work engagement ( P < 0.001), and greater turnover intentions ( P = 0.03). Concerns about being perceived as less capable in the workplace due to menopausal symptoms were reported by 51.2% of respondents. A striking gap exists between the workplace measures desired by women, such as formal menopause policies and managerial training (65.4%-68%), and their actual implementation (2%-6.3%). CONCLUSIONS This study reveals an exigent need for increased awareness and structural changes to support working women going through menopause. The findings have far-reaching implications for not just promoting gender equity and well-being but are also pivotal for maintaining a diversified, engaged, and effective workforce.

Abstract
Wearable sleep trackers are increasingly used in applied psychology. Particularly, the recent boom in the fitness tracking industry has resulted in a number of relatively inexpensive consumer-oriented devices that further enlarge the potential applications of ambulatory sleep monitoring. While being largely positioned as wellness tools, wearable sleep trackers could be considered useful health devices supported by a growing number of independent peer-reviewed studies evaluating their accuracy. The inclusion of sensors that monitor cardiorespiratory physiology, diurnal activity data, and other environmental signals allows for a comprehensive and multidimensional approach to sleep health and its impact on psychological well-being. Moreover, the increasingly common combination of wearable trackers and experience sampling methods has the potential to uncover within-individual processes linking sleep to daily experiences, behaviors, and other psychosocial factors. Here, we provide a concise overview of the state-of-the-art, challenges, and opportunities of using wearable sleep-tracking technology in applied psychology. Specifically, we review key device profiles, capabilities, and limitations. By providing representative examples, we highlight how scholars and practitioners can fully exploit the potential of wearable sleep trackers while being aware of the most critical pitfalls characterizing these devices. Overall, consumer wearable sleep trackers are increasingly recognized as a valuable method to investigate, assess, and improve sleep health. Incorporating such devices in research and professional practice might significantly improve the quantity and quality of the collected information while opening the possibility of involving large samples over representative time periods. However, a rigorous and informed approach to their use is necessary.

Abstract
Workplace violence against healthcare workers is a widespread phenomenon with very severe consequences for the individuals affected and their organizations. The role played by psychosocial working conditions in healthcare workers' experiences of violence from patients and their family members has received relatively scant attention. In the present study, we investigated the idea that psychosocial working conditions (workload, job control, supervisor support, and team integration), by affecting the well-being and job performance of healthcare workers, play a critical role in the relationship between patients' demands and the escalation of workplace violence. Specifically, we tested the hypothesis that psychosocial working conditions moderate the relationship between patients' demands and workplace violence. Participants were 681 healthcare workers distributed in 55 work groups of three public healthcare facilities in Italy. Multilevel analysis showed significant interactions between patients' demands and each of the investigated psychosocial factors on workplace violence, which in all the cases were in the expected direction. The results suggest that improving the quality of the psychosocial work environment in which healthcare workers operate may be a critical aspect in the prevention of workplace violence.

Abstract
Workaholism is a current issue in modern organizations with well-characterized implications for individual health and well-being. Yet, the affective experience of workaholics at work and their emotional reactivity to job stressors have been poorly investigated, with the few available studies being cross-sectional or based on retrospective reports obtained outside the working time. Here, we conducted an experience sampling study to characterize workaholics' affective experience during work and their emotional reactivity to workday accumulation and momentary workload. A total of 139 full-time back-office workers participated in a 3-day protocol by reporting on their hedonic tone and momentary workload up to six times per workday. Multilevel modeling was used to investigate the relationship between trait workaholism and job-related hedonic tone as well as the cross-level interactions between workaholism and both workday accumulation and momentary workload. As expected, our results showed lower job-related hedonic tone for individuals with higher workaholic tendencies, with workaholism interacting with the two investigated job stressors. However, contrary to our hypotheses, we found that workaholism weakened, rather than strengthening, the negative trend of hedonic tone over the levels of both predictors, a result possibly explained by a blunted reactivity condition due to chronic job strain. Moreover, we corroborated previous findings suggesting worse outcomes in workaholic women compared to workaholic men. Organizations should consider taking action to monitor and manage the workaholism levels in the workforce and to create a psychosocial work environment that discourages the enactment of workaholic tendencies.

Abstract
Worldwide, population aging and unhealthy lifestyles have increased the incidence of high-risk health conditions such as cardiovascular diseases, sleep apnea, and other conditions. Recently, to facilitate early identification and diagnosis, efforts have been made in the research and development of new wearable devices to make them smaller, more comfortable, more accurate, and increasingly compatible with artificial intelligence technologies. These efforts can pave the way to the longer and continuous health monitoring of different biosignals, including the real-time detection of diseases, thus providing more timely and accurate predictions of health events that can drastically improve the healthcare management of patients. Most recent reviews focus on a specific category of disease, the use of artificial intelligence in 12-lead electrocardiograms, or on wearable technology. However, we present recent advances in the use of electrocardiogram signals acquired with wearable devices or from publicly available databases and the analysis of such signals with artificial intelligence methods to detect and predict diseases. As expected, most of the available research focuses on heart diseases, sleep apnea, and other emerging areas, such as mental stress. From a methodological point of view, although traditional statistical methods and machine learning are still widely used, we observe an increasing use of more advanced deep learning methods, specifically architectures that can handle the complexity of biosignal data. These deep learning methods typically include convolutional and recurrent neural networks. Moreover, when proposing new artificial intelligence methods, we observe that the prevalent choice is to use publicly available databases rather than collecting new data.

Abstract
OBJECTIVES Characterizing daily patterns of sleep, stress, presleep worry, and mood in adolescents with and without insomnia symptomatology. DESIGN Two months of continuous wearable tracking and daily diary ratings. SETTING Free-living conditions. PARTICIPANTS Ninety-three adolescents (59 girls; 16-19 years old) with (N = 47; 26 with clinical and 21 with sub-clinical) and without (N = 46; control) DSM-5 insomnia symptomatology. MEASUREMENTS Fitbit Charge 3 tracked sleep, heart rate, and steps. Evening electronic diaries collected ratings of daily stress, presleep worry, and mood. RESULTS While sleep duration (control: 6.88 ± 1.41 hours; insomnia: 6.92 ± 1.28 hours), architecture, timing, and night-to-night variability were similar between groups, the insomnia group reported higher levels of stress and worry, being mainly related to "school". At the intraindividual level, stress and worry predicted shorter sleep duration and earlier wake up times, which, in turn, predicted higher stress the following day. Moreover, higher-than-usual stress predicted higher sleep-time heart rate, with a more consistent effect in adolescents with insomnia. Results were overall consistent after controlling for covariates and several robustness checks. CONCLUSIONS There is a bidirectional relationship between daily stress and sleep, with daily stress negatively impacting sleep, which in turn leads to more stress in adolescents with and without insomnia symptoms. Findings also highlight the complexity of insomnia in adolescence, in which the core clinical features (perceived sleep difficulties) and the critical factors (stress/worry) implicated in the pathophysiology of the disorder are not necessarily reflected in objective sleep indicators.

Abstract
Abstract. Experience sampling methods are increasingly used in workplace stress assessment, yet rarely developed and validated following the available best practices. Here, we developed and evaluated parsimonious measures of momentary stressors (Task Demand and Task Control) and the Italian adaptation of the Multidimensional Mood Questionnaire as an indicator of momentary strain (Negative Valence, Tense Arousal, and Fatigue). Data from 139 full-time office workers that received seven experience sampling questionnaires per day over 3 workdays suggested satisfactory validity (including weak invariance cross-level isomorphism), level-specific reliability, and sensitivity to change. The scales also showed substantial correlations with retrospective measures of the corresponding or similar constructs and a degree of sensitivity to work sampling categories (type and mean of job task, people involved). Opportunities and recommendations for the investigation and the routine assessment of workplace stress are discussed.

Abstract
New sleep technologies have become pervasive in the consumer space, and are becoming highly common in research and clinical sleep settings. The rapid, widespread use of largely unregulated and unstandardized technology has enabled the quantification of many different facets of sleep health, driving scientific discovery. As sleep scientists, it is our responsibility to inform principles and practices for proper evaluation of any new technology used in the clinical and research settings, and by consumers. A current lack of standardized methods for evaluating technology performance challenges the rigor of our scientific methods for accurate representation of the sleep health facets of interest. This special article describes the rationale and priorities of an interdisciplinary effort for rigorous, standardized, and rapid performance evaluation (previously, "validation") of new sleep and sleep disorders related technologies of all kinds (eg, devices or algorithms), including an associated article template for a new initiative for publication in Sleep Health of empirical studies systematically evaluating the performance of new sleep technologies. A structured article type should streamline manuscript development and enable more rapid writing, review, and publication. The goal is to promote rapid and rigorous evaluation and dissemination of new sleep technology, to enhance sleep research integrity, and to standardize terminology used in Rigorous Performance Evaluation papers to prevent misinterpretation while facilitating comparisons across technologies.

Abstract
Sleep-tracking devices, particularly within the consumer sleep technology (CST) space, are increasingly used in both research and clinical settings, providing new opportunities for large-scale data collection in highly ecological conditions. Due to the fast pace of the CST industry combined with the lack of a standardized framework to evaluate the performance of sleep trackers, their accuracy and reliability in measuring sleep remains largely unknown. Here, we provide a step-by-step analytical framework for evaluating the performance of sleep trackers (including standard actigraphy), as compared with gold-standard polysomnography (PSG) or other reference methods. The analytical guidelines are based on recent recommendations for evaluating and using CST from our group and others (de Zambotti and colleagues; Depner and colleagues), and include raw data organization as well as critical analytical procedures, including discrepancy analysis, Bland-Altman plots, and epoch-by-epoch analysis. Analytical steps are accompanied by open-source R functions (depicted at https://sri-human-sleep.github.io/sleep-trackers-performance/AnalyticalPipeline_v1.0.0.html). In addition, an empirical sample dataset is used to describe and discuss the main outcomes of the proposed pipeline. The guidelines and the accompanying functions are aimed at standardizing the testing of CSTs performance, to not only increase the replicability of validation studies, but also to provide ready-to-use tools to researchers and clinicians. All in all, this work can help to increase the efficiency, interpretation, and quality of validation studies, and to improve the informed adoption of CST in research and clinical settings.

Abstract
We evaluated the performance of Fitbit Charge 3™ (FC3), a multi-sensor commercial sleep-tracker, for measuring sleep in adolescents against gold-standard laboratory polysomnography (PSG). Single-night PSG and FC3 sleep outcomes were compared in thirty-nine adolescents (22 girls; 16-19 years), 12 of whom presented with clinical/subclinical DSM-5 insomnia symptoms (7 girls). Discrepancy analysis, Bland-Altman plots, and epoch-by-epoch analyses were used to evaluate FC3 performance. The influence of several factors potentially affecting FC3 performance (e.g., sex, age, body mass index, firmware version, and magnitude of heart rate changes between consecutive PSG epochs) was also tested. In the sample of healthy adolescents, FC3 systematically underestimated PSG total sleep time by about 11 min and sleep efficiency by 2.5%, and overestimated wake after sleep onset by 9 min. Proportional biases were detected for "light" and "deep" sleep duration, resulting in significant underestimation of these parameters for those participants having longer PSG N1+ N2 and N3 durations, respectively. No significant systematic bias was detected for sleep efficiency and sleep onset latency. Epoch-by-epoch analysis showed sleep-stage sensitivity (average proportion of PSG epochs correctly classified by the device for a given sleep stage) of 68% for wake, 78% for "light" sleep, 59% for "deep" sleep, and 69% for rapid eye movement (REM) sleep in healthy sleepers. Similar results were found in the sample of adolescents with insomnia symptoms. Body mass index was positively associated with FC3-PSG discrepancies in wake after sleep onset (R2 = .16, p = .048). The magnitude of the heart rate acceleration/deceleration between consecutive PSG epochs was an important factor affecting FC3 classifications of sleep stages. Our results are in line with a general trend in the literature, suggesting better performance for the recently introduced multi-sensor devices compared to motion-only devices, although further developments are needed to improve accuracy in sleep stage classification and wake detection. Further insight is needed to determine factors potentially affecting device performance, such as accuracy and reliability (consistency of performance over time), in different samples and conditions.

Abstract
The routine assessment of workplace stress is mostly based on standardized self-report tools, including generic psychosocial risk indicators (G-PRIs) designed to fit very heterogeneous occupational sectors. However, the use "by default" of such indicators might be inadequate when they fail to characterize the specificity of the work environment; hence, the inclusion of more contextualized indicators (C-PRIs) has been recommended. We aimed at evaluating the additional contribution of three C-PRIs (Work-Family Conflict, Emotional Demands, and Excessive Demands from Patients) in predicting individual outcomes (Emotional Exhaustion, Turnover Intentions) compared to commonly used G-PRIs (e.g., Demand, Control, Support), in a sample of 787 healthcare workers involved in a routine workplace stress assessment. Multilevel hierarchical regression supported the additional contributions of C-PRIs in predicting both outcomes over G-PRIs, sex, age and shift work. More robust and consistent evidence emerged for Emotional Exhaustion, which was significantly predicted by all C-PRIs, whereas Turnover Intentions was only predicted by the C-PRI Emotional Demands. Importantly, not all G-PRIs showed a relationship with the two outcomes. Taken together, our results support the importance of including C-PRIs in workplace stress assessment carried out by organizations, which should be selected based on literature search and discussion with the stakeholders.

Abstract
Abstract
Introduction
Commercial wearable devices have shown the capability of collecting and processing multisensor information (motion, cardiac activity), claiming to be able to measure sleep-wake patterns and differentiate sleep stages. While using these devices, users should be aware of their accuracy, sources of measurement error and contextual factors that may affect their performance. Here, we evaluated the agreement between Fitbit Charge 2™ and PSG in adults, considering effects of two different sleep classification methods and pre-sleep alcohol consumption.
Methods
Laboratory-based synchronized recordings of device and PSG data were obtained from 14 healthy adults (42.6±9.7y; 6 women), who slept between one and three nights in the lab, for a total of 27 nights of data. On 10 of these nights, participants consumed alcohol (up to 4 standard drinks) in the 2 hours before bedtime. Device performance relative to PSG was evaluated using epoch-by-epoch and Bland-Altman analyses, with device data obtained from a data-management platform, Fitabase, via two
methods
one that accounts for short wakes (SW, awakenings that last less than 180s) and one that does not (not-SW).
Results
SW and not-SW methods were similar in scoring (96.76% agreement across epochs), although the SW method had better accuracy for differentiating “light”, “deep”, and REM sleep; but produced more false positives in wake detection. The device (SW-method) classified epochs of wake, “light” (N1+N2), “deep” (N3) and REM sleep with 56%, 77%, 46%, and 62% sensitivity, respectively. Bland-Altman analysis showed that the device significantly underestimated “light” (~19min) and “deep” (~26min) sleep. Alcohol consumption enhanced PSG-device discrepancies, in particular for REM sleep (p=0.01).
Conclusion
Our results indicate promising accuracy in sleep-wake and sleep stage identification for this device, particularly when accounting for short wakes, as compared to PSG. Alcohol consumption, as well as other potential confounders that could affect measurement accuracy should be further investigated.

Abstract
Sleep is crucial for the proper functioning of bodily systems and for cognitive and emotional processing. Evidence indicates that sleep is vital for health, well-being, mood, and performance. Consumer sleep technologies (CSTs), such as multisensory wearable devices, have brought attention to sleep and there is growing interest in using CSTs in research and clinical applications. This article reviews how CSTs can process information about sleep, physiology, and environment. The growing number of sensors in wearable devices and the meaning of the data collected are reviewed. CSTs have the potential to provide opportunities to measure sleep and sleep-related physiology on a large scale.

Abstract
Wearable sensors are promising instruments for conducting both laboratory and ambulatory research in psychophysiology. However, scholars should be aware of their measurement error and the conditions in which accuracy is achieved. This study aimed to assess the accuracy of a wearable sensor designed for research purposes, the E4 wristband (Empatica, Milan, Italy), in measuring heart rate (HR), heart rate variability (HRV), and skin conductance (SC) over five laboratory conditions widely used in stress reactivity research (seated rest, paced breathing, orthostatic, Stroop, speech task) and two ecological conditions (slow walking, keyboard typing). Forty healthy participants concurrently wore the wristband and two gold standard measurement systems (i.e., electrocardiography and finger SC sensor). The wristband accuracy was determined by evaluating the signal quality and the correlations with and the Bland-Altman plots against gold standard-derived measurements. Moreover, exploratory analyses were performed to assess predictors of measurement error. Mean HR measures showed the best accuracy over all conditions. HRV measures showed satisfactory accuracy in seated rest, paced breathing, and recovery conditions but not in dynamic conditions, including speaking. Accuracy was diminished by wrist movements, cognitive and emotional stress, nonstationarity, and larger wrist circumferences. Wrist SC measures showed neither correlation nor visual resemblance with finger SC signal, suggesting that the two sites may reflect different phenomena. Future studies are needed to assess the responsivity of wrist SC to emotional and cognitive stress. Limitations and implications for laboratory and ambulatory research are discussed.

Abstract
Abstract
Background. Treatment options for patients with hormone receptor positive metastatic breast cancer (MBC) and prior treatment with aromatase inhibitors (AIs) include EE or PF. To date no direct comparison has been presented between EE and Fulvestrant plus Cyclin-dependent Kinase 4/6 (CDK4/6) inhibitors in this setting. The objective of this study was to compare the efficacy of EE to PF or AF or EF in the treatment of metastatic HR+, HER2- breast cancer pre-treated with AIs.
Methods. An indirect comparison with a network meta-analysis comparing EE with PF or AF or EF in the treatment of metastatic HR+, HER2- breast cancer pre-treated with AIs was performed. The Progression-Free-Survival (PFS) was the primary end point of all our indirect comparisons. Efficacy data were expressed as Hazard Ratio (HR) and 95% Confidence Interval (95CI), assuming an α-error of 5% as index of statistical significance.
Results. All the data of the BOLERO-2 trial, the Bachelot et al network meta-analysis (Breast Cancer Treat Rep 2014), the Paloma-3, the Monarch-2, and the prECOG trials were analyzed and indirectly compared in a network meta-analysis. 6 orders of comparison were performed: AF vs PL, PF vs EE, AF vs EE, EF vs AF, EF vs PF and EF vs EE. The pooled HR and 95%CI are reported in table1.
Table 1: difference in PFS between comparatorsComparisonsHR (95% CI)AF vs PF1.202 (0.87-1.661) p = 0.265PF vs EE1.674 (0.995-2.818) p = 0.89AF vs EE2.012 (1.09-3.714) p = 0.025EF vs AF1.085 (0.681-1.728) p = 0.731EF vs PF1.304 (0.804-2.117) p = 0.283EF vs EE2.183 (1.072-4.444) p = 0.031Everolimus-exemestane (EE), palbociclib-fulvestrant (PF), abemaciclib-fulvestrant (AF), everolimus-fulvestrant (EF).
Conclusions. Till today EE and PF represent active and approved treatments for patients with metastatic HR+, HER2- breast cancer treated with AIs. The results of Monarch-2 study with AF vs Fulvestrant and prECOG study with FE vs Fulvestrant were recently presented and were included in this metaanalysis, while the results of Ribociclib and Fulvestrant vs Fulvestrant (Monaleesa-3 study) are not currently available.
These studies generally show that combination of hormone therapies with Everolimus or CDK4/6 inhibitors are better than hormone-therapy alone, however no direct comparisons between these treatment combinations exist in literature. The results of our indirect treatment comparisons suggests that EE is similar and, in some cases, it may be even better than other treatment options. The optimal treatment strategy and sequence for patient with MBC and prior treatment with AIs should be evaluated in clinical trials. Meanwhile these data could be considered together with safety and the economic profile to help physicians in daily clinical practice.

Abstract
Resveratrol (3,4’,5-trihydroxy-trans-stilbene) is a natural phytoalexin found in grapes and wine, which has been extensively studied for a wide range of biological effects. A large number of stilbene-containing derivatives have displayed antioxidant and antiproliferative activities on various cancer cell lines. In this study, a series of stilbene hybrids 1-9, previously reported as peroxisome proliferator-activated receptor (PPAR) agonists, were assessed at micromolar concentrations using MTT cell viability assay in C2C12 and MCF7 cell lines. The modulation of oxidative stress was also evaluated by measuring the protective effects on reactive oxygen species (ROS) production induced or not by oxidative stimulus. Among these, compounds 2 and 8 showed significant radical scavenging activity.

Abstract
Prostatitis is a common prostate disease that could be promoted by bacterial or non-bacterial infectious agents. In addition, inflammatory pathways involved in prostatitis have been increasingly studied, and herbal extracts endowed with anti-inflammatory effects are under investigation, individually or in combination, for their efficacy in alleviating the burden of inflammation, with possible improvements in symptoms. Serenoa repens (Serenoa), in combination with Crocus sativus (Crocus) and Pinus massoniana (Pinus), has previously shown to improve sexual function and limit urinary symptoms in patients suffering from concomitant erectile dysfunction and lower urinary tract symptoms. In this context, the aim of the present study is to evaluate the efficacy of Serenoa, Crocus and Pinus extracts, either alone or in combination, on immortalized prostate cells (PC3) and in an experimental model of bacterial prostatitis constituted by ex vivo prostate specimens challenged with lipopolysaccharide (LPS). We found that the tested extracts were able to reduce ROS production by PC3 cells and NFkB and PGE2 activity in prostate specimens challenged with LPS. In addition, the pharmacological association of the extracts displayed synergistic effects indicating a rational use of the mixture of the tested extracts as a novel anti-oxidant and anti-inflammatory formulation in bacterial prostatitis. Finally, we performed analytical and in vitro evaluation to better characterize the phytochemical profile and the mechanism of action of selected secondary metabolites.

Abstract
A pivotal role in osteoporosis development is played by radical oxygen species (ROS), the increased production of which is related to inhibited osteoblastic activity and bone formation. A new field of research could involve medicinal plants with antioxidant and protective effects in osteoporosis. Furthermore, considering the multifactorial metabolic aspects of osteoporosis, the pharmacological association of multiple medicinal plants could improve patient response. The aim of the present study is to evaluate in vitro and in vivo the protective effects of a natural formula containing lactoferrin 12%, Equisetum arvensis ES 54%, soy isoflavones 34% and vitamin D3 0.002%, in PBMC and C2C12 cells and in the bone matrix of young (3-month-old) and aged (12-month-old) female Sprague-Dawley rats, following chronic (21 days) administration. In this context, we assayed the activities of several inflammation and bone homeostasis mediators, such as IL-6, TNFα, PGE2, osteoprotegerin, RANK, RANKL and NFkB. In vitro studies showed that natural formula (5-1000μg/ml) was able to significantly inhibit ROS and PGE2 production. In the same concentration range, the natural formula inhibited both TNFα and IL-6 gene expression. In the in vivo studies, we administered to young and aged female rats the natural formula at 5mg/rat for 21 days, finding a significant reduction in inflammatory PGE2 and NFkB activity. Nevertheless, we observed a significant increase in osteoprotegerin/RANKL ratio only in aged rats, compared to the respective control group. In conclusion, our findings corroborate the rational use of natural formula in the prevention and management of osteoporotic disease.

Abstract
Imoviral is a natural product formulation containing a mixture of uncaria, shiitake and ribes extracts. All ingredients are recognized as antioxidant, anti-inflammatory agent and immunomodulant. In order to evaluate the rational basis of extract mixture as immunomodulatory agent, we tested the effect of Imoviral formulation on macrophage response to lipopolysaccharide (LPS)-induced stress. The effect was evaluated as variation of reactive oxygen species (ROS) and prostaglandin E2 (PGE2) production and as cytokine gene expression. The extract did not affect cell viability up to 250 μg/ml. Treatment with extract (10-150 μg/ml) reduced ROS and PGE2 production as well as IL-8 and TNF-α gene expression. A pre-treatment with extract blunted LPS-induced production of ROS and PGE2, markers of oxidative and inflammatory stress, as well as the gene expression of all cytokines tested, indicators, in vitro, of immune response activation. In conclusion, we demonstrated that Imoviral formulation could be a useful tool to modulate the immune function, reducing the oxidative and inflammatory markers related to bacterial attack. Experimental data suggest that Imoviral extract mixture could also represent a preventive pharmacological strategy to enhance cell resistance to bacterial infections.

Abstract
AIM Aim of this study was to evaluate the effects of phytocomplexes of Uncaria, Shiitake and Ribes in terms of viability and inflammatory response on immune cell-derived cultures. METHODS Standardized extracts of Uncaria, Shitake and Ribes and their commercial formulation were tested on cell lines PBMC, U937 and macrophage. The activity was evaluated in terms of cell viability (MTT test), variations of oxidative marker release (ROS and PGE2) and modulatory effects on immune response (gene expression of IL-6, IL-8 and TNFα, RT-PCR). RESULTS Cell viability was not affected by extracts, except subtle variations observed only at higher doses (>250 µg/mL). The extract mixture was well tolerated, with no effects on cell viability up to doses of 500 µg/mL. Pre-treatment of macrophages with subtoxic doses of the extracts reduced the basal release of oxidative markers and enhanced the cell response to exogenous oxidant stimulation, as revealed by ROS and PGE2 release reduction. The same treatment on macrophage resulted in a selective modulation of the immune response, as shown by an increase of IL-6 mRNA and, partially, IL-8 mRNA, while a reduction was observed for TNFα mRNA. CONCLUSION Data confirm that extracts and their formulations can act as regulator of the immune system with mechanisms involving the oxidative stress and the release of selected proinflammatory cytokines.

Abstract
Plants of cranberry (Vaccinium macrocarpon) furnish edible fruits and derivates that have been used for the prevention and treatment of urinary tract infections. In the present work we compare two commercial extracts that contain proanthocyanins (PACs) at 4 percent and 20 percent for antimicrobial, antiproliferative, antiradical and protective properties against oxidative stress on cell lines. Both extracts showed antimicrobial activity (MIC values range 3-100 microg/ml). Extract at 20 percent PACs showed higher antiproliferative activity against HepG2 and MCF7 cells, but not against C2C12 cells. Both extracts showed a dose-dependent free-radical scavenging capacity, and a protective effect on the cell damage was also revealed by reduction of intracellular active oxygen species release. Cranberry extracts confirmed antioxidative properties and efficacy in reduction of cell viability that resulted stronger against tumor cells. The pretreatment with cranberry extracts, furthermore, reveal an increase of cell resistance against oxidative stress, suggesting a potential role as a dietary supplement in preventing free-radical damage. The proanthocyanidin content is critical to determine the extract efficacy. In cellular experiments the extracts resulted clearly differentiated in their activity, and the activity was strongly influenced by PACs content. Only in DPPH test the free radical scavenging activity seemed to be directly related to proanthocyanidins content.

Abstract
INTRODUCTION Rhamnus alpinus L. (Rhamnaceae), a traditional plants in the flora of the Abruzzo region, is known to contain active anthraquinone secondary metabolites. However, the content of anthraquinones varies among R. alpinus samples depending on collection season and site. Thus, using simple, reliable and accurate analytical methods for the determination of anthraquinones in R. alpinus extracts allows comparative study of different methods of extraction. OBJECTIVE After a partial validation of an HPLC method for the simultaneous determination of five anthraquinones, aloe-emodine, rheine, emodine, chrysophanol and physcione, in the bark of R. alpinus, we compared three different methods of extraction. METHODOLOGY Anthraquinones were extracted from the bark of R. alpinus using different techniques (methanol maceration, ultrasonic and supercritical CO(2) extraction). Separation and quantification of anthraquinones were accomplished using a reversed-phase C(18) column with the mobile phase of H(2)O-methanol (40 : 60, v/v, 1% formic acid) at a wavelength of 254 nm. The qualitative analyses were also achieved at wavelength of 435 nm. RESULTS All calibration curves were linear over the concentration range tested (10-200 mM) with the determination coefficients >or=0.991. The detection limits (S/N = 3) were 5 mM for each analytes. All five anthraquinones were found in the samples tested at concentrations reported in experimental data. CONCLUSION The described HPLC method and optimised extraction procedure are simple, accurate and selective for separation and quantification of anthraquinones in the bark of R. alpinus and allow evaluation of the best extraction procedure between the tested assays.

Abstract
Artichoke, dandelion, turmeric extracts and rosemary essential oil are commonly used as ingredients in many herbal preparations to treat hepatic and gallbladder disorders. In the present work we compare the activity of each single extract with a commercial mixture for antiproliferative, antiradical and protective effects against induced oxidant stress effect. In ABTS and DPPH tests, turmeric extract is the most active, followed by artichoke and dandelion. All samples exhibited antiproliferative activity in a dose-dependent manner against HepG2 cells. In the same cell lines, the protective effect of pre-treatment with the extracts were detected by evaluating the prostaglandin E2 release, a marker of oxidative stress induced by hydrogen peroxide. The treatments with the extracts were efficient in reducing the release of PGE2 induced by oxidative stimulus. The positive results of the cell viability test, together with the protective and antiradical activity confirm the rationale for the use of these ingredients in commercial formulations as a health aid tool in modern phytotherapy.

Abstract
Verbascum mallophorum is part of a large family of Scrophulariaceae consisting of more than 360 species. Verbascum mallophorums contains diverse polysaccharides, iroid glycosides, flavonoids, saponins, volatile oils and phenylentanoids. Verbascum has been used in popular medicine for treating wounds, chilblains, respiratory ailments, acne and arthritic disturbances. Inducible nitric oxide synthase (iNOS) represents one of the three isoforms that produce nitric oxide using L-arginine as a substrate in response to an increase in superoxide anion activated by NF-kappaB. It is implicated in different pathophysiological events and its expression increases greatly during an inflammatory process due to oxidative stress. In our study we reproduced an inflammatory state by treating THP-1 cells (human myelomonocytic leukaemia) with pro-inflammatory stimuli, such as LPS and IFN-gamma, obtaining an up-regulation both in the expression and in the activity of iNOS. The aim of our work is to investigate the possible antiinflammatory action of verbascoside extract from Verbascum mallophorum using a concentration of 100 muM. Our results show a significant decrease in the expression and activity of iNOS and extracellular O2- when cells were treated with verbascoside. Based on these results we hypothesize that verbascoside extract from Verbascum mallophorum has anti-inflammatory properties since it reduces the production of superoxide radicals and consequently reduces the activity of iNOS.

Abstract
Eight entities of the genus Hypericum that spontaneously grow on the Central Italy (Appennino Umbro-Marchigiano) have been studied under the morphological, histochemical and phytochemical aspects. From the morphological standpoint, they differ in the shape and size of flowers and leaves and in the dimension and distribution of the secretory structures through the various parts of the plant. It has been possible, with the histochemical and phytochemical studies, to localize and identify some secondary metabolites inside the secretory structures.

Abstract
Recent studies suggest a role for prefrontal cortex abnormalities in the pathogenesis of attention deficit/hyperactivity disorder (ADHD). We evaluated young drug-naive ADHD outpatients without MRI structural abnormalities to detect prefrontal cortex regional cerebral blood flow (rCBF) functional dysregulation; correlation between age and rCBF; and correlation between symptoms profile and rCBF. Functional brain activities (i.e. rCBF), neuropsychological attention performance and symptom profile were evaluated respectively by single photon emission computerized tomography (SPECT) scan, Stroop Test and the Child Attention Problem Rating Scale. There was a decreased rCBF in the left dorso lateral prefrontal cortex (DLPFC) compared to the right DLPFC of the subjects. In addition, there were positive correlations between age and relative rCBFs of the dorsolateral and orbital prefrontal cortex, and negative correlations between age and absolute rCBFs of the dorsolateral and orbital prefrontal cortex. Finally, higher levels of right relative rCBF and lower levels of left relative rCBF were predictors of higher severity of clinical symptom expression and neuropsychological attention impairment. The results of this study highlight the role of the DLPFC blood flow impairment in the pathogenesis of ADHD even in young subjects without structural abnormalities.
