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.

Q: The Cochrane Central Register of Controlled Trials, PubMed Medline and Latin American and Caribbean Health Science literature databases were searched, and searches made by hand of identified papers, to source relevant data. (BIOSIS Previews) were searched. There were no language restrictions.', 'Studies were evaluated by two reviewers independently. Only clinical trials were included that were published in the English, Spanish and Portuguese languages and were performed on humans. Articles were excluded when the examiners were not calibrated; when they did not compare manual and electronic probing techniques; when they did not measure the clinical attachment level (CAL); and when the subjects did not present destructive periodontal disease or had already received periodontal treatment.', 'The quality of the identified studies was assessed and standardised data extracted. Only two studies met all the selection criteria so no meta-analysis was performed.', 'Only two of the 37 identified articles were included in the review. The results of these two studies showed that the mean variance and the absolute mean difference between CAL measurements for the two types of probes were not statistically different.

A: Do manual and electronic probes have similar reliability in the measurement of untreated periodontitis?

Q: Regular physical activity is an effective non-pharmacological therapy for prevention and control of hypertension. However, the underlying mechanisms are not fully understood. Accumulating evidence shows that the elevated vascular tone in hypertension is a consequence of the 'ion channel remodelling' that occurs during sustained high BP. The present study investigated the effects of aerobic exercise on the electrical remodelling of L-type Ca(2+) (Cav 1.2) and large-conductance Ca(2+) -activated K(+) (KCa 1.1) channels in mesenteric arteries (MAs) from spontaneously hypertensive rats (SHRs).", 'SHRs and normotensive (Wistar-Kyoto) rats were subjected to aerobic training or kept sedentary, and vascular mechanical and functional properties were evaluated.', 'Exercise did not affect the heart weight, but reduced the heart rate and body weight in SHR. In mesenteric arterial myocytes, exercise normalized the increased Cav 1.2 and KCa 1.1 current density in SHRs. Exercise also ameliorated the increased open probability and mean open time of the single KCa 1.1 channel in hypertension. The isometric contraction study revealed that both nifedipine (Cav 1.2 channel blocker) and NS11021 (KCa 1.1 channel activator) induced concentration-dependent vasorelaxation in MAs precontracted with noradrenaline. Exercise normalized the increased sensitivity of tissues to nifedipine and NS11021 in SHR. Furthermore, protein expression of the Cav 1.2 α1C -subunit together with the KCa 1.1 α- and β1-subunit was significantly increased in SHRs; and exercise ameliorated these molecular alterations in hypertension.

A: Does chronic exercise normalize changes in Cav 1.2 and KCa 1.1 channels in mesenteric arteries from spontaneously hypertensive rats?

Q: reduced fetal movements (RFM) are experienced by 46-50% of women prior to the diagnosis of stillbirth. Empowering women with evidenced-based information regarding RFM may allow for prompt contact with a health care provider and access to appropriate management. Use of the Internet is growing in popularity as a source of pregnancy information to aid mothers׳ decision-making. This study aimed to identify and examine the available online information for pregnant women regarding RFM.', 'a systematic search was performed using Google, Yahoo and Bing to identify the most popular websites giving information about RFM. The websites were assessed for readability, accountability and content using the Flesh-Kincaid ease of readability score; the Silberg criteria; and by comparison to evidence-based guidelines respectively. Chat forums were assessed using a qualitative thematic analysis.', "70 information articles and 63 chat forums were analysed from 77 unique websites. The mean readability score was 65.7 (suitable for the average 13-15 year old) and therefore above the recommended level set for health materials; only 15 (21.4%) websites met all accountability criteria; and 43 (70%) websites contained information that was not in accordance with evidence-based recommendations. Typical questions on forums were 'Is this normal? What should I do?' and responses were 'Better safe than sorry', 'There is no harm in calling'.

A:
Is online information for women and their families regarding reduced fetal movements of variable quality , readability and accountability?
