instruction:
In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
question:
Context: This study investigated whether a 7-week yoga intervention could improve physical function, perceived stress, and mental/emotional wellness in elderly participants.', '8 participants (66.5\xa0±\xa00.3 years) attended 2 60-min Hatha yoga sessions/week for 7 weeks, and performed pre- and post-intervention assessments. Balance was assessed using a 5-test battery. Flexibility was measured by sit-and-reach and shoulder flexibility tests. Functional mobility tests included 8-ft up-and-go, 5 chair stands, and 4-m walk. Participants completed SF-12, exhaustion level, and Perceived Stress Scale (PSS) questionnaires.', 'SF-12 Mental Component Summary scores, exhaustion levels, and PSS scores improved post-intervention. No differences were found for physical function measures.\Question: Does yoga reduce perceived stress and exhaustion levels in healthy elderly individuals?
answer:
Yoga participation can improve mental/emotional wellness, exhaustion levels, and stress levels in elderly individuals, even without measurable improvements in physical function. Clinicians and health practitioners who work with the elderly should consider yoga as a potential therapeutic modality for improving important aspects of quality of life in this population.


question:
Context: L-Carnosine inhibits senescence of somatic cells and displays anticancer activity. Here we analyzed if L-carnosine (20 mM) retards senescence of human peritoneal mesothelial cells (HPMCs) and inhibits progression of ovarian cancer cells.', 'Experiments were performed with primary HPMCs established from patients undergoing abdominal surgery and with three ovarian cancer cell lines: A2780, OVCAR-3 and SKOV-3.', 'L-Carnosine retards senescence of HPMCs plausibly via inhibition of mitochondria-related oxidative stress. Prolonged exposure of HPMCs to L-carnosine prevented senescent HPMC-dependent exacerbation of cancer cell adhesion, migration, invasion and proliferation, which may be linked with decreased secretion of various pro-cancerogenic agents by HPMCs. Cancer cells exposed directly to L-carnosine displayed reduced viability, increased frequency of apoptosis and unaltered proliferation.\Question: Does l-Carnosine prevent the Pro-cancerogenic Activity of Senescent Peritoneal Mesothelium Towards Ovarian Cancer Cells?
answer:
L-carnosine may be a valuable anticancer drug, especially in the context of prevention and therapy of intraperitoneal ovarian cancer metastasis.


question:
Context: A previous systematic review showed that atraumatic restorative treatment (ART) can be an option to restore the occlusoproximal cavities in primary teeth; however, few studies fulfilled the criteria of inclusion to generate a high level of evidence.', 'To update the existing systematic review and address questions regarding survival rate of ART restorations compared to the conventional approach in occlusoproximal cavities in primary molars.', 'The search was extended beyond the original search through the PubMed/MEDLINE database up to February 2016. Furthermore, Web of Science and EMBASE were searched. The inclusion criteria were subjects related to the scope of the systematic review. After selection by title and abstract, potentially eligible articles were read in full and included in accordance with exclusion criteria. Meta-analysis was carried out with the outcome being the survival rate of restorations.', 'The search strategy identified 560 potentially relevant studies, in addition to 127 from the original systematic review. A total of four articles were included in the qualitative and quantitative analyses. Meta-analysis showed no statistically significant difference between ART and conventional approaches in survival rate of occlusoproximal cavities (OR = 0.887, 95% CI: 0.574-1.371).\Question: Is aRT an alternative for restoring occlusoproximal cavities in primary teeth - evidence from an updated systematic review and meta-analysis?
answer:

ART restorations have similar survival rate compared to conventional treatment and can be considered an option to restore occlusoproximal cavities in primary molars.
