[EX Q]: Circular RNAs are a subclass of non-coding RNAs detected within mammalian cells. This study was designed to test the roles of a circular RNA circ-Foxo3 in senescence using in vitro and in vivo approaches.', 'Using the approaches of molecular and cellular biology, we show that a circular RNA generated from a member of the forkhead family of transcription factors, Foxo3, namely circ-Foxo3, was highly expressed in heart samples of aged patients and mice, which was correlated with markers of cellular senescence. Doxorubicin-induced cardiomyopathy was aggravated by ectopic expression of circ-Foxo3 but was relieved by silencing endogenous circ-Foxo3. We also found that silencing circ-Foxo3 inhibited senescence of mouse embryonic fibroblasts and that ectopic expression of circ-Foxo3 induced senescence. We found that circ-Foxo3 was mainly distributed in the cytoplasm, where it interacted with the anti-senescent protein ID-1 and the transcription factor E2F1, as well as the anti-stress proteins FAK and HIF1α.

[EX Q]: Thromboembolic events represent a clinically significant cause of neurological morbidity during the endovascular management of cerebral aneurysms. We have implemented an anti-thromboembolic regimen consisting of pre- and postoperative dual antiplatelet therapy, as well as postoperative anticoagulation using heparin and dextran. The aims of our study were to examine the effect of this regimen on thromboembolic rates during elective aneurysm coiling, and to elucidate risk factors associated with the development of thromboembolic events in this setting.', 'We conducted a retrospective review of patients who underwent elective intracranial aneurysm coiling between January 2005 and February 2012. The primary outcome of interest was the occurrence of a clinically significant peri-procedural thromboembolic event. Secondary outcomes included the occurrence of a central nervous system (CNS) or systemic hemorrhage.', 'During the study period, 312 patients underwent elective aneurysm coiling and six (2\xa0%) thromboembolic events occurred; three (1\xa0%) occurred in the group that received the anti-thromboembolic regimen (261 patients) and three (6\xa0%) occurred in the group that did not receive the regimen (51 patients), resulting in a statistically significant difference (P\u2009=\u20090.024). Both the presence of a hypercoagulable state (P\u2009=\u20090.014) and the lack of the anti-thromboembolic regimen (P\u2009=\u20090.043) were significantly associated with the occurrence of a thromboembolic event.

[EX Q]: Enhanced insulin sensitivity is commonly seen following Roux-en-Y gastric bypass surgery (RYGB) whereas symptomatic hypoglycemia post-RYGB seems to occur infrequently. It is unclear how different plasma glucose and insulin responses are in patients with symptomatic hypoglycemia (SX-RYGB) versus those who remain asymptomatic (ASX-RYGB), nor when compared with non-surgical controls with varying degrees of insulin sensitivity.', 'Plasma glucose and insulin concentrations were determined following a 75-g oral glucose challenge in five groups: symptomatic and asymptomatic patients following RYGB (n = 9 each) and overweight/obese controls, divided into three subgroups (n = 30 each) on the basis of degree of insulin sensitivity measured by the insulin suppression test.', 'SX-RYGB group had higher 30-min glucose after oral glucose compared with the ASX-RYGB group (p = 0.04). The two groups did not differ in peak glucose and insulin concentrations, nadir glucose concentration, or insulin-to-glucose ratio 30 min after oral glucose. These values were significantly different from the three control groups, and peak insulin concentrations post-RYGB were increased at every degree of insulin sensitivity as compared with the control groups.
