Each resource guide offers: - Monthly themes focused on emotions, empathy, relationships, conflict resolution, bullying prevention, problem solving, decision making, teamwork, and self-esteem - Literature-based lessons with curriculum integrations for using the lessons as part of language arts, social studies, science, math, art, and music - Easy-to-implement lesson formats
OBJECTIVE: To provide a reference for the standardization of Tibetan medicine.METHOD: Investigating the hospital preparations , Tibetan formulated products, and the literature recorded preparations in the Tibetan, Qinghai, Gansu, Sichuan and Yunnan Provinces. Moreover, the varieties, original bases and standard conditions of these preparations were analyzed. According to Chinese Pharmacopoeia, Tibetan medicine part of ministerial standard, Tibetan medicine standards and related monographs and literatures of Tibetan medicine.
RESULT: About 502 various of herbs were used in 711 hospital preparations from 40 medical institutions, Tibetan formulated products from Tibetan pharmaceutical factories, and 439 literature recorded preparations. About 154 herbs were used in more than 10 preparations, while most of them were Tibetan endemic species. About 416 medicinal varieties have the original documented basis, including 287 botanicals, 78 animal medicines, 51 mineral medicines, involving a total of 94 families, 261 genus and 643 species of botanical origin (including species of the next grade), 35 families, 52 genera and 61 species of the animal origin (including species of the next grade). About 122 varieties of herbs were cross-used in the traditional Chinese medicine and Tibetan medicine, about 80% of Tibetan medicinal varieties are produced in the Tibetan Areas of Tibet Plateau. About 293 medicinal varieties were contained in the above standards. Most of the herb's standards only contains character, indentification, and examination, except for 8 varieties which were recorded in the Chinese Pharmacopoeia (2010) as Tibetan medicine.
CONCLUSION: This study of quality standard of Tibetan medicine should have an emphasis on the general varieties, especially the study on the arrangement research and the efficacious material basis of the varieties and the original, as well as term standardization of the National Medicine.
OBJECTIVES: To evaluate the acute and chronic effects of yoga practice. DESIGN: Quantitative study using a one-group pre-posttest design. SETTING: Visao Futuro Institute, Porangaba, Sao Paulo, Brazil. PARTICIPANTS: 22 volunteers (7 men and 15 women). INTERVENTION: Six weeks of a tantric yoga program (TYP), 50 minutes per session, held twice a week from 8 a.m. to 9 a.m. The local ethics committee approved the protocol. OUTCOME MEASURES: Data were collected in the first week and at the end of the sixth week of TYP. Salivary cortisol concentration (SCC) was used to measure physiology of distress and to analyze the short- and long-term effects of TYP. Psychological distress was evaluated by applying a specific perceived stress questionnaire (PSQ). Results (mean+/-standard deviation) were analyzed by Wilcoxon test (p<0.05). RESULTS: SCC decreased 24% after the first (0.66+/-0.20 mug/dL versus 0.50+/-0.13 mug/dL) and last (1.01+/-0.37 versus 0.76+/-0.31 mug/dL) sessions, showing the short-term effect of yoga. Long-term effects were analyzed by daily rhythm of cortisol production. In the beginning, volunteers showed altered SCC during the day, with nighttime values (0.42+/-0.28) higher than those at noon (0.30+/-0.06). After the TYP, SCC was higher in the morning (1.01+/-0.37) and decreased during the day, with lower values before sleep (0.30+/-0.13). The TYP was also efficient to reduce PSQ scores (0.45+/-0.13 versus 0.39+/-0.07). Specifically, the irritability, tension, and fatigue domains on the PSQ decreased (0.60+/-0.20 versus 0.46+/-0.13), as did the fear and anxiety domains (0.54+/-0.30 versus 0.30+/-0.20). CONCLUSION: Over the short term, TYP led to the decrease of cortisol production. Over the long term, TYP induced higher cortisol production in the morning and lower production in the evening. Those effects contributed to the physical and mental well-being of the participants.

BACKGROUND: College students are vulnerable to a critical period in developmental maturation, facing rigorous academic work and learning how to function independently. Western aerobic exercise (WAE), such as running and bicycling, has been shown to improve mood and relieve stress. However, college students often have low levels of physical activity. Yoga is an ancient physical and mental practice that may affect mood and stress. However, rigorous studies examining the psychological effects of yoga are rare in peerreviewed Western journals. The aim of this research was to establish preliminary evidence for the acute effects of Vinyasa yoga on affect and stress in young-adult college students. METHODS: Twenty healthy college students age 18 years and older were recruited to participate in this pilot study. Participants attended a Vinyasa yoga class at a local studio twice weekly for 8 weeks. Affect and stress were assessed before and after each yoga session. Measures included the Positive and Negative Affective Schedule (PANAS) and the Cohen Perceived Stress scale. RESULTS: Positive affect scores increased significantly (p < 0.05) for 14 of the 16 yoga sessions (mean increase = 23.2%). Negative affect decreased significantly from pre- to postyoga (p < 0.05) for 15 of the 16 sessions (mean decrease = 22%). Repeated measures ANOVAs examining pre-post composite scores across all 8 weeks showed significant changes in PANAS, but not stress scores. CONCLUSIONS: Findings suggest that yoga practice is associated with acute improvements in affect in a young-adult college population. Future research is needed to examine the extent to which different types of yoga address the needs of different college sub-populations (e.g., eating disordered, overweight/obese, sedentary, and smokers).

Chest physical therapy (CPT) has an important role in a medical team to assist in resolving the critical problems deriving from chronic lung disease. These critical problems include increased secretion volume, difficult breathing or dyspnea, ineffective coughing, inability to be weaned off a ventilator, and physical deterioration resulting from low aerobic capacity and endurance after prolonged bed rest. The inability to be weaned off a ventilator does not only result from secretion production or muscle weakness, but other conditions including chest stiffness or immobility. The procedure to increase chest mobility includes specific chest stretching and mobilization. Chest wall-stretching exercises were composed of thoracic rotation and anterior compression with stretching in sitting position, trunk extension and rib torsion in supine lying, and lateral stretching in side lying. These exercises were given to the patient as a regular daily program along with postural drainage, percussion, breathing exercise and limb exercises. The expired tidal volume, dyspnea level, and chest expansion were evaluated and clinical efficiency was analyzed during CPT, compared to Pre-CPT and Post-CPT with Bloom table. The results showed a significant clinical improvement of expired tidal volume, reduction in dyspnea level, and increase in chest expansion.
To test the effects of cortisol on affective experience, the authors orally administered a placebo, 20 mg cortisol, or 40 mg cortisol to 85 men. Participants' affective responses to negative and neutral stimuli were measured. Self-reported affective state was also assessed. Participants in the 40-mg group (showing extreme cortisol elevations within the physiological range) rated neutral stimuli as more highly arousing than did participants in the placebo and 20-mg groups. Furthermore, within the 20-mg group, individuals with higher cortisol elevations made higher arousal ratings of neutral stimuli. However, cortisol was unrelated to self-reported affective state. Thus, findings indicate that acute cortisol elevations cause heightened arousal in response to objectively nonarousing stimuli, in the absence of effects on mood.

Patients with posttraumatic stress disorder (PTSD) have elevated sympathetic nervous system reactivity and impaired sympathetic and cardiovagal baroreflex sensitivity (BRS). Device-guided slow breathing (DGB) has been shown to lower blood pressure (BP) and sympathetic activity in other patient populations. We hypothesized that DGB acutely lowers BP, heart rate (HR), and improves BRS in PTSD. In 23 prehypertensive veterans with PTSD, we measured continuous BP, ECG, and muscle sympathetic nerve activity (MSNA) at rest and during 15 min of DGB at 5 breaths/min ( n = 13) or identical sham device breathing at normal rates of 14 breaths/min (sham; n = 10). Sympathetic and cardiovagal BRS was quantified using pharmacological manipulation of BP via the modified Oxford technique at baseline and during the last 5 min of DGB or sham. There was a significant reduction in systolic BP (by −9 ± 2 mmHg, P < 0.001), diastolic BP (by −3 ± 1 mmHg, P = 0.019), mean arterial pressure (by −4 ± 1 mmHg, P = 0.002), and MSNA burst frequency (by −7.8 ± 2.1 bursts/min, P = 0.004) with DGB but no significant change in HR ( P > 0.05). Within the sham group, there was no significant change in diastolic BP, mean arterial pressure, HR, or MSNA burst frequency, but there was a small but significant decrease in systolic BP ( P = 0.034) and MSNA burst incidence ( P = 0.033). Sympathetic BRS increased significantly in the DGB group (−1.08 ± 0.25 to −2.29 ± 0.24 bursts·100 heart beats −1

NEW & NOTEWORTHY Posttraumatic stress disorder is characterized by augmented sympathetic reactivity, impaired baroreflex sensitivity, and an increased risk for developing hypertension and cardiovascular disease. This is the first study to examine the potential beneficial effects of device-guided slow breathing on hemodynamics, sympathetic activity, and arterial baroreflex sensitivity in prehypertensive veterans with posttraumatic stress disorder.
<p>The concept of recovery strategies includes various ways to achieve a state of well-being, prevent underrecovery syndromes from occurring and re-establish pre-performance states. A systematic application of individualised relaxation techniques is one of those. Following a counterbalanced cross-over design, 27 sport science students (age 25.22 +/- 1.08 years; sports participation 8.08 +/- 3.92 h/week) were randomly assigned to series of progressive muscle relaxation, systematic breathing, power nap, yoga, and a control condition. Once a week, over the course of five weeks, their repeated sprint ability was tested. Tests (6 sprints of 4 s each with 20 s breaks between them) were executed on a non-motorised treadmill twice during that day intermitted by 25 min breaks. RM-ANOVA revealed significant interaction effects between the relaxation conditions and the two sprint sessions with regard to average maximum speed over all six sprints, F(4,96) = 4.06, P = 0.004, [Formula: see text] = 0.15. Post-hoc tests indicated that after systematic breathing interventions, F(1,24) = 5.02, P = 0.033, [Formula: see text] = 0.18, participants performed significantly better compared to control sessions. As the focus of this study lied on basic mechanisms of relaxation techniques in sports, this randomised controlled trial provides us with distinct knowledge on their effects, i.e., systematic breathing led to better performances, and therefore, seems to be a suited relaxation method during high-intensity training.</p>

Objective The aim of this study is to evaluate the acute impact of breathing exercises based on yogic pranayama on cravings in abstaining smokers.Methods Participants visited the laboratory on two occasions 24 h apart and were asked to abstain from smoking12 h prior to the first visit until the end of the second visit. Smokers (N096) were randomly allocated to a yogic breathing exercise (YBG) or video control (VCG) group. The former was instructed on breathing exercises, practised these for 10 min and asked to use these when experiencing cravings until the next visit. The latter was shown a breathing exercise video for 10 min and asked to concentrate on their breathing. Strength of urges to smoke, other craving measures and mood and physical symptoms associated with cigarette withdrawal were assessed at the beginning and end of the first visit, and again at the second visit.
Results At immediate follow-up, in the laboratory, all craving measures were reduced in YBG compared with VCG (strength of urges: F(1, 96)016.1, p<0.001; cigarette craving: F(1, 96)0 11.3, p00.001; desire to smoke: F(1, 96)06.6, p00.012). There was no effect on mood or physical symptoms. Adherence to the breathing exercise regimen in the following 24 h was low, and at 24 h follow-up, there was no evidence of reduced cravings in YBG compared with VCG.
Conclusions Simple yogic-style breathing exercises can reduce cigarette craving acutely in the laboratory. Further
<p>BACKGROUND: In 2012, yoga was practiced by 20 million Americans, of whom 82% were women. A recent literature review on prenatal yoga noted a reduction in some pregnancy complications (ie, preterm birth, lumbar pain, and growth restriction) in those who practiced yoga; to date, there is no evidence on fetal response after yoga. OBJECTIVES: We aimed to characterize the acute changes in maternal and fetal response to prenatal yoga exercises using common standardized tests to assess the well-being of the maternal-fetal unit. STUDY DESIGN: We conducted a single, blinded, randomized controlled trial. Uncomplicated pregnancies between 28 0/7 and 36 6/7 weeks with a nonanomalous singleton fetus of women who did not smoke, use narcotics, or have prior experience with yoga were included. A computer-generated simple randomization sequence with a 1:1 allocation ratio was used to randomize participants into the yoga or control group. Women in the yoga group participated in a 1-time, 1 hour yoga class with a certified instructor who taught a predetermined yoga sequence. In the control group, each participant attended a 1-time, 1 hour PowerPoint presentation by an obstetrician on American Congress of Obstetricians and Gynecologists recommendations for exercise, nutrition, and obesity in pregnancy. All participants underwent pre- and postintervention testing, which consisted of umbilical and uterine artery Doppler ultrasound, nonstress testing, a biophysical profile, maternal blood pressure, and maternal heart rate. A board-certified maternal-fetal medicine specialist, at a different tertiary center, interpreted all nonstress tests and biophysical profile data and was blinded to group assignment and pre- or postintervention testing. The primary outcome was a change in umbilical artery Doppler systolic to diastolic ratio. Sample size calculations indicated 19 women per group would be sufficient to detect this difference in Doppler indices (alpha, 0.05; power, 80%). Data were analyzed using a repeated-measures analysis of variance, a chi(2), and a Fisher exact test. A value of P < .05 was considered significant. RESULTS: Of the 52 women randomized, 46 (88%) completed the study. There was no clinically significant change in umbilical artery systolic to diastolic ratio (P = .34), pulsatility index (P = .53), or resistance index (P = .66) between the 2 groups before and after the intervention. Fetal and maternal heart rate, maternal blood pressure, and uterine artery Dopplers remained unchanged over time. When umbilical artery indices were individually compared with gestational age references, there was no difference between those who improved or worsened between the groups. CONCLUSION: There was no significant change in fetal blood flow acutely after performing yoga for the first time in pregnancy. Yoga can be recommended for low-risk women to begin during pregnancy.</p>

Seven oleanane-type triterpene saponin bisdesmosides, perennisaponins N-T (<i>1</i>-<i>7</i>), were newly isolated from a methanol extract of daisy, the flowers of <i>Bellis perennis</i> L. (Asteraceae). The structures were determined based on chemical and physicochemical data and confirmed using previously isolated related compounds as references. The isolates, including 13 previously reported perennisaponins A-M (<i>8</i>-<i>20</i>), exhibited anti-proliferative activities against human digestive tract carcinoma HSC-2, HSC-4, and MKN-45 cells. Among them, perennisaponin O (<i>2</i>, IC<sub>50</sub> = 11.2, 14.3, and 6.9 μM, respectively) showed relatively strong activities. The mechanism of action of <i>2</i> against HSC-2 was found to involve apoptotic cell death.

AimsTo design, construct and validate a pharmacokinetics simulator that offers students hands‐on opportunities to participate in the design, administration and analysis of oral and intravenous dosing regimens.
Methods
The Alberta Drug Administration Modeller (ADAM) is a mechanical patient in which peristaltic circulation of water through a network of silicone tubing and glass bottles creates a representation of the outcomes of drug absorption, distribution, metabolism and elimination. Changing peristaltic pump rates and volumes in bottles allows values for pharmacokinetic constants to be varied, thereby simulating differences in drug properties and in patient physiologies and pathologies. Following administration of methylene blue dye by oral or intravenous routes, plasma and/or urine samples are collected and drug concentrations are determined spectrophotometrically. The effectiveness of the simulator in enhancing student competence and confidence was assessed in two undergraduate laboratory classes.
Results
The simulator effectively models one‐ and two‐compartment drug behaviour in a mathematically‐robust and realistic manner. Data allow calculation of numerous pharmacokinetic constants, by traditional graphing methods or with curve‐fitting software. Students' competence in solving pharmacokinetic problems involving calculations and graphing improved significantly, while an increase in confidence and understanding was reported.
Conclusions
The ADAM is relatively inexpensive and straightforward to construct, and offers a realistic, hands‐on pharmacokinetics learning opportunity for students that effectively complements didactic lectures.

People feel grateful when they have benefited from someone’s costly, intentional, voluntary effort on their behalf. Experiencing gratitude motivates beneficiaries to repay their benefactors and to extend generosity to third parties. Expressions of gratitude also reinforce benefactors for their generosity. These social features distinguish gratitude from related emotions such as happiness and feelings of indebtedness. Evolutionary theories propose that gratitude is an adaptation for reciprocal altruism (the sequential exchange of costly benefits between nonrelatives) and, perhaps, upstream reciprocity (a payit-forward style distribution of an unearned benefit to a third party after one has received a benefit from another benefactor). Gratitude therefore may have played a unique role in human social evolution.
