Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: 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.

Output: Does yoga reduce perceived stress and exhaustion levels in healthy elderly individuals?


Input: Consider Input: G. rigescens Franch (Long Dan Cao in Chinese) is a well-known TCM herb. It is clinically used with other drugs for the treatment of brain diseases such as epilepsy, postherpetic neuralgia in China.', 'In our previous study, the 11 dihydroxybenzoates compounds with NGF mimicking activity from G. rigescens Franch were found. In the present study, the neurogenesis and neuroprotection of a mixture of benzoates (\xa0n-GS) were investigated in animal level.', 'The NGF mimicking activity of n-GS from G. rigescens Franch was examined in PC12 cells. The neurogenesis effects of n-GS were investigated in ICR mice with 5-bromo-2-deoxyuridine (BrdU) and neuronal neclei (NeuN) double immunostaining. Furthermore, the neuroprotection effects of n-GS on the memory in a scopolamine (SCO)-induced mouse model were evaluated with animal behavior tests.', "The NGF-mimicking function and neurogenesis of n-GS were observed in PC12 cells and in normal mice. Subsequently, we investigated the effects of n-GS on the memory in a SCO-induced mouse model. In Y-maze test, SCO significantly lowered the alternation. This finding was reversed by n-GS and donepezil (DONE). SCO significantly impaired the mice's performance in novel object recognition (NOR) and Morris water maze (MWM) tests. The time spent to explore the novel object was longer in the n-GS- and DONE-treated groups than in the SCO control group. In the MWM test, the escape latency of n-GS- and DONE-treated groups was shorter than that of the SCO control group. Mechanism study showed that SCO significantly reduced superoxide dismutase (SOD) but increased the activities of acetylcholinesterase (AChE) and the levels of malondialdehyde (MDA) in the hippocampus and cerebral cortex, which all can be improved by n-GS and DONE. Additionally, the phosphorylation of type 1 insulin-like growth factor (IGF-1) receptor, extracellular signal-regulated kinase (ERK), and cAMP responsive element-binding (CREB) protein in the hippocampus was significantly up-regulated in the treatment group compared with that in the SCO group.

Output: Does benzoate fraction from Gentiana rigescens Franch alleviate scopolamine-induced impaired memory in mice model in vivo?


Input: Consider Input: This study was to examine the association between plasma retinol binding protein 4 (RBP4) levels and the complexity of angiographic coronary lesion in patients with coronary artery disease (CAD).', 'A cross-sectional and prospective study was carried out in Guangzhou Chinese population. 672 persons were evaluated by medical history, clinical examination, coronary angiography, and fasting plasma samples, and were followed prospectively for 3 years. We measured the plasma RBP4 levels in 447 women (201 with stable CAD and 246 with acute coronary syndrome [ACS]). Coronary lesions were classified as having a simple or complex appearance based on the visual estimation of the coronary angiograms. Median plasma RBP4 levels were significantly higher in stable CAD patients with complex coronary lesions (n\xa0=\xa084) than in those with simple lesions (n\xa0=\xa0117) (38.78[range 32.65-46.91] vs. 30.78 [range 24.48-36.08] μg/ml, P\xa0<\xa00.001). Multiple logistic regression analysis demonstrated that higher RBP4 levels were independently associated with a 23% higher risk for complex lesions (odds ratio 1.228, 95% confidence interval [CI] 1.061 to 1.358; P\xa0=\xa00.031). Among the ACS patients, who had higher RBP4 levels than the stable CAD patients, those with multiple complex lesions had significantly higher median RBP4 levels than those with a single complex lesion (46.47\xa0μg/ml [range 37.68-53.29] vs. 38.15\xa0μg/ml [range 32.26-44.56], P\xa0<\xa00.001). Total plasma RBP4 levels were predictors of cardiac death (hazard ratio [HR]: 1.102; 95% CI: 1.086 to 1.191; P\xa0=\xa00.012) after adjustment for traditional risk factors for CAD.


Output: Is circulating retinol binding protein 4 associated with coronary lesion severity of patients with coronary artery disease?
