We investigated the effect of variations in ice shell thickness and of the tiger stripe fractures crossing Enceladus' south polar terrain on the moon's tidal deformation by performing finite element calculations in three-dimensional geometry. The combination of thinning in the polar region and the presence of faults has a synergistic effect that leads to an increase of both the displacement and stress in the south polar terrain by an order of magnitude compared to that of the traditional model with a uniform shell thickness and without faults...

BACKGROUND: Although delayed ejaculation (DE) is typically characterized as a persistently longer than anticipated or desired time to ejaculation (or orgasm) during sexual activity, a timing-based definition of DE and its association with serum testosterone has not been established in a large cohort. AIM: To examine in an observational study estimated intravaginal ejaculatory latency time (IELT) and masturbatory ejaculation latency time (MELT) in men self-reporting DE, assess the association of IELT and MELT with serum testosterone levels, and determine whether correlation with demographic and sexual parameters exist...

Initially, the transcatheter aortic valve replacement procedure was approved only for patients with aortic stenosis that was both severe and symptomatic who either also had too high a risk of aortic valve replacement surgery to have the surgery or who had a high risk for the surgery. Between the years 2012 and 2015, the death rate at 30 days declined from an initial rate of 7.5% to 4.6%. There has also been more use of the transfemoral approach over the years. In 2016, the transcatheter aortic valve replacement was approved for patients with aortic stenosis at intermediate risk of surgery...

We analyzed Cassini Imaging Science Subsystem (ISS) images of the plume of Enceladus to derive particle number densities for the purpose of comparing our results with those obtained from other Cassini instrument investigations. Initial discrepancies in the results from different instruments, as large as factors of 10-20, can be reduced to ∼2 to 3 by accounting for the different times and geometries at which measurements were taken. We estimate the average daily ice production rate, between 2006 and 2010, to be 29 ± 7 kg/s, and a solid-to-vapor ratio, S/V > 0...

INTRODUCTION: Triploidy is a lethal chromosomal numeric abnormality, characterized on extra haploid set of chromosomes. It occurs in 2 to 3% of conceptuses and accounts for approximately 20% of chromosomally abnormal first-trimester miscarriages. As such, triploidy is estimated to occur in 1 of 3,500 pregnancies at 12 weeks', 1 in 30,000 at 16 weeks', and 1 in 250,000 at 20 weeks' gestation. CASE REPORT: We present a case of second-trimester triploidy diagnosed prenataly at our center...

BACKGROUND: The efficacy of adipose-derived stem cells (ADSCs) in alleviating erectile dysfunction (ED) of diabetic rats has been demonstrated mainly through a paracrine effect. However, exosomes (EXOs), which are important bioactive substance vectors secreted by ADSCs, have never been associated with ED. AIM: To investigate the effect of ADSC-derived EXOs on erectile function in a type 2 diabetic ED rat model. METHODS: EXOs were isolated from the supernatants of cultured ADSCs by ultracentrifugation...

Methane on Mars is a topic of special interest because of its potential association with microbial life. The variable detections of methane by the Curiosity rover, orbiters, and terrestrial telescopes, coupled with methane's short lifetime in the martian atmosphere, may imply an active gas source in the planet's subsurface, with migration and surface emission processes similar to those known on Earth as "gas seepage." Here, we review the variety of subsurface processes that could result in methane seepage on Mars...

INTRODUCTION: Although pelvic fracture urethral injuries (PFUIs) are rare, approximately half these patients will report erectile dysfunction (ED) after their injuries. The anatomic relations of the cavernosal nerves and arteries to the bones of the pelvis and the urethra put these structures at significant risk at the time of PFUI. This review examines the epidemiology, evaluation, and management of ED in this patient population. AIM: To evaluate the epidemiology, pathophysiology, diagnosis, and management of patients with ED after PFUI...

REVIEW
Matthew S Brennan, Ryan M Barlotta, Jay Simhan
INTRODUCTION: Surgical frailty is a previously unrecognized clinical entity that objectifies a multiorgan decrease in physiologic reserve in those undergoing surgery. Although penile implantation has been demonstrated to be an effective means of restoring erectile function in patients whose previous conservative measures have failed, there are limited data regarding the assessment of frailty in patients undergoing penile implantation. AIM: To review the various objective methods used to describe surgical frailty in medical and surgical disciplines, report on methodologies of frailty assessment, and discuss the relevance of surgical frailty in the preoperative evaluation of patients undergoing implantation of an inflatable penile prosthesis...
