BACKGROUND The association of preawake (difference between pre- and postwaking blood pressure (BP)) and sleep-through surge (difference between sleeping nadir and postwaking BP) with cardiovascular events is unclear. Examination of factors associated with surge may provide novel insights. We examined the association of race, which associates with nocturnal dipping, and plasma renin activity (PR...

To avoid co-surge the mass flows should be kept balanced. Still co-surge can occur when operating close to the surge line due to disturbances between the two mass flows. In that case the control system needs to detect the co-surge oscillation and take proper actions. The simulation model is used to evaluate detection and control algorithms, which are then tested in vehicle. −0.25 0 0.25 0.5 0.7...

Until now, clinicians have been relying solely on LH activity-dependent triggering of final oocyte maturation and thus taken it for granted that the natural midcycle FSH surge is biologically redundant. However, it is time to question this paradigm. Evidence from clinical studies hint that in a yet-to-be-defined subset of patients, dual LH and FSH surge is advantageous compared with LH-only sur...

a ruptured sinus of valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. a 36-year-old woman presented with low-threshold dyspnea on exertion and fever. transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgi...

This paper presents a new analysis of the effects of ambient temperature variations on the surge characteristics of turbo heat pumps. To this end, an analytical model capable of predicting unsteady behavior of surge in turbo heat pumps has been developed. In compression systems, surge is mostly caused by the compressor work exceeding the mechanical inertia of the system. In refrigeration system...

Background and Purpose: Candida endocarditis is an infrequent disease with a high mortality rate, which commonly occurs in immunosuppressed patients with cardiac valve replacement. We reported a 70-year-old woman diagnosed with Candida prosthetic valve endocarditis (PVE). This study also involved a review of all published cases of Candida PVE from 1970. Case report: Herein, we reported a 70-ye...

In sheep, the surge mode of gonadotropin secretion is sexually differentiated, i.e. the LH surge is present in the female, but not in the male. The present study tested the hypothesis that sexual differentiation of the LH surge mechanism reflects a sex difference in the pattern of GnRH, and that prenatal androgens abolish the surge mode of GnRH secretion. We monitored the pattern of GnRH secret...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

Gulf surges are transient disturbances that propagate along the Gulf of California (GoC) from south to north, transporting cool moist air toward the deserts of northwest Mexico and the southwest United States during the North American monsoon. They have been shown to modulate precipitation and have been linked to severe weather and flooding in northern Mexico and the southwest United States. Th...

The optimal time period for intrauterine insemination (IUI) in relation to either luteinizing hormone (LH) surge or human chorionic gonadotrophin (HCG) administration leading to the best pregnancy rates has not been determined. In this study, 856 consecutive human menopausal gonadotrophin (HMG)-stimulated and 49 natural unstimulated IUI cycles carried out at a reproductive medicine unit affilia...
