BACKGROUND & OBJECTIVES: Music captures attention, triggers a range of emotions, alters or regulates mood, increases work output, heightens arousal, induces states of higher functioning, reduces inhibitions and encourages rhythmic movement. Music has ergo-genic effect as well, it increases exercise performance, delays fatigue and increases performance and endurance, power and strength. Our study tried to evaluate the effect of music on exercise performance in young untrained subjects...

Orexins peptides exert a prominent role in arousal-related processes including stress responding, by activating orexin-1 (OX1R) and orexin-2 (OX2R) receptors located widely throughout the brain. Stress or orexin administration stimulates hyperarousal, adrenocorticotropic hormone (ACTH) and corticosterone release, and selective OX1R blockade can attenuate several stress-induced behavioral and cardiovascular responses but not the hypothalamic-pituitary-adrenal (HPA) axis activation. As opposed to OX1R, OX2R are preferentially expressed in the paraventricular hypothalamic nucleus which is involved in the HPA axis regulation...

BACKGROUND: Post-traumatic stress disorder (PTSD) is the most widely assessed form of mental distress in cross-cultural studies conducted amongst populations exposed to mass conflict and displacement. Nevertheless, there have been longstanding concerns about the universality of PTSD as a diagnostic category when applied across cultures. One approach to examining this question is to assess whether the same factor structure can be identified in culturally diverse populations as has been described in populations of western societies...

BACKGROUND: Anhedonia, the decreased interest and pleasure, is often described as 'flat' or 'blunted' positive affect (PA). Yet, little is known about PA functioning in anhedonic individuals' daily lives. The current study investigates PA reactivity to pleasurable experiences in anhedonia together with its relevant temporal dynamics (i.e., variability, instability, and inertia), and expands current knowledge by exploring the role of arousal therein. METHODS: Using the Experience Sampling Method (ESM), we collected 90 assessments of real-life PA experiences across 30 days in 18-24 year old individuals with anhedonia (N=69) and without anhedonia (N=69)...

Study Objectives: Upper airway surgery is often recommended to treat OSA patients who cannot tolerate continuous positive airways pressure (CPAP). However, the response to surgery is variable, potentially because it does not improve the non-anatomical factors (i.e. loop gain and arousal threshold) causing OSA. Measuring these traits clinically might predict responses to surgery. Our primary objective was to test the value of loop gain and arousal threshold to predict surgical success defined as 50% reduction in apnea-hypopnea index (AHI) and AHI <10 events/hr post-surgery...

Positive airway pressure (PAP) is the preferred treatment for obstructive sleep apnea (OSA), but adherence is low. Educational or ongoing supportive intervention improves the number of PAP adherent patients from the 50% to the 70% range. A common side effect of PAP is increased awakenings. This prospective trial examined baseline polysomnographically derived sleep efficiency and arousal index in PAP adherent and nonadherent patients, and in patients needing sedating medicines to attain PAP adherence versus those who did not need such medicines...

INTRODUCTION: Sexual relationship is a basis for mental health and continuity of the healthy generation. There are very few studies on the female sexual functioning, especially in India. Sterilization being the most common contraceptive method, sexual functioning in women undergoing this surgical intervention has not been adequately explored. Available studies have found conflicting results; some have reported that sterilization has positive effects on sexual functioning since anxiety of getting pregnant is abolished...

Infrared thermography (IRT) is increasingly applied as a noninvasive technique for measuring surface body temperature alterations related to e.g. stress, emotions and leg pathologies in avian species. As a basis for the validation of IRT as a future tool for veterinary diagnostics such as detection and/or prediction of subclinical footpad pathologies in broiler chickens, this study explored effects of manual restraint at two different ages on footpad temperatures. Head region temperatures were applied as additional measures of emotional arousal and stress...

BACKGROUND: Contemporary treatments assume that the inability to downregulate negative emotional arousal is a key problem in the development and maintenance of psychopathology and that lack of effective regulation efforts and a preference to use maladaptive regulation strategies is a primary mechanism. Though ubiquitous, there is limited empirical evidence to support this assumption. Therefore, the aim of the current study was to examine whether self-reported emotion dysregulation equated to difficulties reducing emotional arousal during a behavioral task and to primary use of maladaptive strategies to manage negative emotions...

Anxiety has been proposed to influence psychophysiological reactivity in children and adolescents. However, the extant empirical literature has not always found physiological reactivity to be associated with anxiety in youth. Further, most investigations have not examined psychophysiological reactivity in real time over the course of acute stress. To test the impact of anxiety disorder status on autonomic arousal in youth, we compared youth with primary anxiety disorders (N = 24) to typically developing (TD) youth (N = 22) on heart rate (HR), heart rate variability (HRV), and respiratory sinus arrhythmia (RSA) during an acute stressor in which youth received error-related feedback...

REVIEW
Barney S Graham
Respiratory syncytial virus (RSV) is an important and ubiquitous respiratory pathogen for which no vaccine is available notwithstanding more than 50 years of effort. It causes the most severe disease at the extremes of age and in settings of immunodeficiency. Although RSV is susceptible to neutralizing antibody, it has evolved multiple mechanisms of immune evasion allowing it to repeatedly infect people despite relatively little genetic diversity. Recent breakthroughs in determining the structure and antigenic content of the fusion (F) glycoprotein in its metastable untriggered prefusion form (pre-F) and the stable rearranged postfusion form (post-F) have yielded vaccine strategies that can induce potent neutralizing antibody responses and effectively boost pre-existing neutralizing activity...

Study Objectives: Menopausal transition is associated with increased dissatisfaction with sleep, but the effects on sleep architecture are conflicting. This prospective six-year follow-up study was designed to evaluate the changes in sleep stages and sleep continuity that occur in women during menopausal transition. Methods: Sixty women (mean age 46.0 years, SD 0.9) participated. All women were premenopausal at baseline, and at the six-year follow-up, women were in different stages of menopausal transition...

Organ transplantation is an ideal treatment for certain late-stage diseases. With the report of a penile transplantation in Tygerberg Hospital, South Africa, this topic has, once again, aroused exploration in the field. At present, two penile transplantation operations have been performed and gained some positive results. Patients can gain void standing, erectile function and better cosmetic appearance. However, debates and potential risks still exist. Here, we briefly review the progress of studies in this filed and discusses the potential risks and debates in penile transplantation...

To examine the factors that influence the inter-individual differences in the changes in primary motor cortex (M1) excitability seen after motor learning, we investigated the relationship between the amplitude of transcranial magnetic stimulation-induced motor evoked potentials (MEP) and short-latency afferent inhibition (SAI) after motor learning, based on the working hypothesis that SAI can be used to evaluate cortical acetylcholine (ACh) activity. To confirm this working hypothesis, we manipulated the arousal state of the subjects using a vigilance task, the outcomes of which might be correlated with cortical ACh activity, and investigated the effects of arousal state on SAI...

OBJECTIVES: The accuracy of respiratory polygraphy (RP) is limited because of the absence of electroencephalography (EEG). Pulse wave amplitude (PWA) reduction has been shown to be a marker of autonomic activation during arousal, and may represent a substitute for obstructive respiratory-related cortical arousal (RRCA). This study tested the hypothesis that PWA could be a surrogate for RRCA in detecting obstructive hypopnea (OH) in a pediatric population. MATERIALS AND METHODS: Two experienced readers scored 30 consecutive polysomnographies (PSG) using standard scoring rules...

Since their first synthesis back in the early 20th century, 1,2,4-triazolo[1,5-a]pyrimidines have aroused increasing interest in very diverse areas ranging from chemotherapy to agriculture or even photography. Their similarity to purines confers a potential bioactivity and this feature has been wisely exploited for therapeutic use, including antifungal, antipyretic, analgesic, antiinflammatory, antitumoral and antiparasitic properties. In this review, we focus on the compounds that these nitrogen heterocycles form with metal ions and their antiparasitic activity and therapeutic potential against two neglected diseases of tropical prevalence, leishmaniasis and Chagas disease...

INTRODUCTION: Affective responses during physical activity (PA) are important for engagement in PA programs and for adherence to a physically active lifestyle. Little is known about the affective responses to PA bouts lasting longer than 45 minutes. Therefore, the aims of the present study were to analyse acute effects on affective responses of a three-hour outdoor PA intervention (mountain hiking) compared to a sedentary control situation and to an indoor treadmill condition. METHODS: Using a randomized crossover design, 42 healthy participants were randomly exposed to three different conditions: outdoor mountain hiking, indoor treadmill walking, and sedentary control situation (approximately three hours each)...

Spin crossover (SCO) materials, revealing the externally tunable transition between two different spin states, arouse great scientific interest due to their perspective application in information storage, display devices and sensing. Of special importance are the molecular systems offering the possibility of multimodal switching within many spin centers. This is achievable in polynuclear clusters consisting of several SCO-active complexes, however, such molecules are very rare. Herein, we report a unique pair of nanometric pentadecanuclear {Fe9[M(CN)8]6(Me3tacn)8}·14MeOH (Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane, M = Re, 1; M = W, 2) clusters exhibiting a thermally induced spin crossover effect on Fe(ii) complexes, that is on both central and external Fe sites embedded in the cyanido-bridged cluster core...

The ventromedial prefrontal cortex's (vMPFC) role in regulating emotions in late life depression (LLD) remains unclarified. We assessed vMPFC activation in an emotional valence blood oxygenation level-dependent (BOLD) functional magnetic neuroimaging (fMRI) task and related the findings to extent of white matter hyperintensities (WMH). Sixteen participants with mild to moderate LLD were compared to 14 similar aged comparison participants. Participants in the scanner viewed words matched for length and arousal, indicated the perceived valence by pressing one of the three buttons i...
