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.

Recently, there has been increasing concern about adverse health effects of exposure to desert dust events. However, the association between dust and the incidence of ischemic heart diseases is unknown. The aim of the present study was to elucidate whether Asian dust (AD), a windblown sand dust originating from mineral soil in China and Mongolia, is associated with the incidence of acute myocardial infarction (AMI).', 'We investigated the data regarding hospitalization because of AMI among 3068 consecutive patients from 4 AMI centers in Fukuoka, Japan, and data for AD from April 2003 to December 2010. We applied a time-stratified case-crossover design to examine the association between AD and the incidence of AMI. Using a conditional logistic regression analysis, we estimated the odds ratios of AMI associated with AD after controlling for ambient temperature and relative humidity. The occurrence of AD events 0 to 4 days before the day of admission was significantly associated with the incidence of AMI. In particular, the occurrence of AD 4 days before admission was significantly associated with the onset of AMI.

Ex Output:
Is desert dust a risk factor for the incidence of acute myocardial infarction in Western Japan?

Intellectual disability (ID) features in numerous heritable medical conditions that result from ATRX mutations. Alpha-thalassemia mental retardation syndrome (ATR-X syndrome) is the most notable manifestation of ATRX dysfunction. In addition to ID, genitourinary and craniofacial abnormalities are regularly observed with or without alpha-thalassemia.', 'The study sought to characterize two cases of ATR-X in a Yemeni family clinically and molecularly.', 'PCR amplification and Sanger sequencing were used to study the ATRX gene in a Yemeni family. Also, methylation-sensitive PCR was used to perform X-inactivation studies. CADD, SNAP2 and PolyPhen-2 helped to predict the functional consequences of the variant.', 'Molecular testing revealed a novel hemizygous missense mutation (c.5666T>G) in the ATRX gene in the two Yemeni brothers. This mutation was found in a heterozygous state in the mother, with the chromosome harboring the mutated allele being under strongly skewed X-inactivation.

Ex Output:
Does a novel missense mutation in ATRX uncovered in a Yemeni family lead to alpha-thalassemia/mental retardation syndrome without alpha-thalassemia?

Oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. The beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. This study was conducted to determine the effects of the hydro-alcoholic root extract of Withania coagulans on CA1 hippocampus oxidative damages following global cerebral ischemia/reperfusion in rat.', 'Male Wistar rats were randomly divided in five groups: control, sham operated, Ischemia/ Reperfiusion (IR), and Withania Coagulans Extract (WCE) 500 and 1000mg/kg + I/R groups. Ischemia was induced by ligation of bilateral common carotid arteries for 30 min after 30 days of WCE administration. Three days after, the animals were sacrificed, their brains were fixed for histological analysis (NISSL and TUNEL staining) and some samples were prepared for measurement of malondialdehyde (MDA) level and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activity in hippocampus.', 'WCE showed neuroprotective activity by significant decrease in MDA level and increase in the SOD, CAT and GPx activity in pretreated groups as compared to I/R groups (p<0.001). The number of intact neurons was increased while the number of TUNEL positive neurons in CA1 hippocampal region in pretreated groups were decreased as compared to I/R group (p<0.001).

Ex Output:
