RESUMO

Six novel Maillard reaction products (MRPs) (1-6) were isolated from the processed Thermopsis lanceolata R. Br. seed extract, along with one biogenetically related intermediate (7). Compounds 1-4 possessed three rare dimerization patterns constructed by cytisine, whereas compounds 5 and 6 represented the first example of the addition products of cytisine and 5,6-dihydroxy-4-hexanolide. Their structures were elucidated by comprehensive spectroscopic data analysis and quantum chemistry calculations including GIAO 13C{1H} NMR and ECD calculation, combined with single-crystal X-ray diffraction analysis. Biologically, compound 3 displayed significant anti-tobacco mosaic virus activity compared with the positive control ningnanmycin.

RESUMO

Seven undescribed thermopsine-based alkaloids (1-7), including one undescribed biogenetically related intermediate (7), were isolated from the seeds of Thermopsis lanceolata R. Br. Compound 1 possessed a 6/6-6 tricyclic skeleton, while compounds 2-6 represented three rare dimerization patterns constructed by quinolizidine alkaloids. Their structures were elucidated by comprehensive spectroscopic data analysis as well as ECD calculations. Biologically, compound 6 displayed significant anti-Tomato spotted wilt virus (TSWV) activity compared with the positive control ningnanmycin. Moreover, compound 1 exhibited good insecticidal activity against Aphis fabae with LC50 value of 25.2 mg/L.

RESUMO

Objective To analyze the overall functioning of children with learning disabilities, and develop individualized exercise rehabilitation protocol using International Classification of Functioning, Disability and Health (ICF). Methods Based on the theoretical framework of ICF and the disease diagnosis of International Classification of Diseases (ICD-11), and with the perspective of child development, the functional profiles of cognition, understanding, attention, thinking, motor, and activity and participation of children with learning disabilities were analyzed. A function-oriented and individulized exercise rehabilitation protocol for children with learning disabilities was constructed in light of ICF bio-psycho-social health paradignm and the theory of somatic and mental interaction. Results The functional performance of children with learning disabilities mainly demonstrated in mental dysfunction in physical functioning in the activities and participation limitations, such as learning and applying knowledge, general tasks and demands, and communication. For the environment factors, products and technology for education, products and technology for culture, recreation and sports, and services, systems and policies could also affect children with learning disabilities. Physical activity was beneficial for children with learning disabilities to improve mental and motor functioning and to effectively enhance intellectual, cognitive, attentional, communication, and mobility skills for the overall development of the children. Physical activity for children with learning disabilities was selected according to WHO guidelines for physical activity and sedentary behavior for children, and moderate to vigorous physical activity for at least 60 minutes, as well as high-intensity training no less than three times a week, together with appropriate physical games and leisure physical activities could effectively improve learning outcomes and reduce learning disabilities. Conclusion The health condition, functioning and motor development of children with learning disability had been analyzed using ICD-11 and ICF, and with the theories of somatic and metal interaction and ICF bio-psycho-social model, the holistic and function-oriented exercise rehabilitation program was developed that recommended at least 60 minutes of moderate intensity physical activity, including aerobic exercise and physical games, per day, and at least three times a week of high intensity physical activity of no less than 30 minutes, including plyometrics and physical competition. The development of individualized function-based exercise rehabilitation programs incorporating the learning disability and motor function characteristics of children could effectively improve the cognitive, attentional, and thinking functions of children with learning disabilities, reduce learning disabilities, and promote the overall development of children.

RESUMO

The discovery of novel, effective, and botanical pesticides is one of the main strategies for modern plant protection and insect pest control. During the search for novel botanical pesticides from natural sources, the seeds of Sophora tonkinensis were systematically investigated to obtain 11 new matrine-type alkaloids (1-11), including one novel matrine-type alkaloid featuring an unprecedented 5/6/6/6 tetracyclic skeleton (1), along with 16 known compounds (12-27). Their structures were elucidated by comprehensive spectroscopic data analysis (IR, UV, NMR, and HRESIMS), ECD calculations, and single-crystal X-ray diffraction. The anti-tobacco mosaic virus (TMV) activity and insecticidal activities against Aphis fabae and Tetranychus urticae of the compounds were also respectively screened using the half-leaf method and spray method. Biological tests indicated that compounds 2, 4, 6, and 26 displayed significant anti-TMV biological activities compared with the positive control ningnanmycin. Compounds 7, 17, and 26 presented moderate activities against A. fabae with LC50 values of 38.29, 18.63, and 23.74 mg/L, respectively. Moreover, compounds 13 and 26 exhibited weak activities against T. urticae.

RESUMO

Three new tuberostemoamide-type alkaloids, stemtuberolines A-C (1-3), four new stenine-type alkaloids, stemtuberolines D-G (4-7), together with five known Stemona alkaloids (8-12), were isolated from the roots of Stemona tuberosa. Their structures were elucidated on the basis of comprehensive spectroscopic data analysis. Stemtuberoline C (3) exhibited significant anti-TMV activity with an inhibition rate of 60.48% at the concentration of 50 µg/mL, while that of ningnamycin, the positive control, was 52.89%.

RESUMO

Objective:To evaluate the effect of mindfulness on psychological rehabilitation in athletes. Methods:Literatures about mindfulness meditation for psychological rehabilitation of athletes were searched in Web of Science, EBSCO, PubMed, Medline, OpenDissertations, Psychology Behavioral Sciences Collection, Academic Search Premier, CNKI, VIP and Wanfang data from January 1st, 2010 to December 31st, 2019. The literature quality was evaluated, and the data were analyzed with Review Manager 5.3. Results:Finally, 18 researches were included. The immediate effect size of mindfulness on psychological rehabilitation was medium to large (d = 0.69, 95%CI 0.53 to 0.86, P < 0.001). There was no significant difference in the follow-up effect of psychological rehabilitation between two groups (d = -0.08, 95%CI -0.33 to 0.16, P = 0.50). The immediate effect of mindfulness was significantly moderated by research quality (I2 = 88.1%, P = 0.004). Conclusion:Mindfulness could improve mood, promote flow, improve acceptance of negative experiences, improve the ability to act on the goal, and increase training investment for athletes, which is moderated by research quality.

RESUMO

Objective:To determine the effectiveness of mind-body exercise, named Yoga, Taijiquan and Qigong, as a complementary and alternative therapy, on depression. Methods:Randomized controlled trials (RCTs) about Yoga, Taijiquan and Qigong for depression were searched from Web of Science, PubMed, EMbase, Cochrane Library, PaycINFO, SPORTDiscu, CBM and CNKI. They were assessed methodological quality, and analyzed with Revman 5.3. Results:A total of 29 RCTs involving 1379 subjects were included. Mind-body exercise alone was an effective intervention on depression (SMD = -0.73, 95%CI -1.00 to -0.47, P < 0.01), with significant heterogeneity and publication bias. Mind-body exercise combined with medicine was also effective on depression (SMD = -0.54, 95%CI-0.71 to -0.36, P < 0.01), without significant heterogeneity and publication bias. Conclusion:Mind-body exercise can be a complement of medicine for depression. Single mind-body exercise is not stable for depression intervention. More long-term and high-quality researches are needed to determine the actual effectiveness on depression in the future.
