Twisting of Inflatable Penile Prosthesis Tubing Leading to Device Malfunction and Required Explantation: A Rare Complication.

Erectile dysfunction (ED), the impairment of achieving and maintaining an erection for satisfactory sexual intercourse, is a common pathology that men experience for a variety of different factors. Conservative treatment for ED includes changing medications, lifestyle modifications, and psychotherapy. Pharmaceutical and nonsurgical interventions include phosphodiesterase-5 inhibitors(PDE-5i), intracavernosal medication injections, and vacuum devices.

A case report of melanosis of the bladder within a bladder diverticulum and associated Aerococcus urinary infection.

Background: Melanosis vesicae is a rare condition characterized by the deposition of melanin within the bladder urothelium.

Case Presentation: We present a case of a 72-year-old male with a history of recurrent urinary retention, bladder diverticula, and concurrent Aerococcus urinary tract infection who presented with left-sided abdominal pain. Cystoscopy revealed diffuse black splotch lesions throughout the bladder and two diverticula.

Wastewater-based epidemiology for comprehensive communitywide exposome surveillance: A gradient of metals exposure.

Community wastewater surveillance is an established means to measure health threats. Exposure to toxic metals as one of the key environmental contaminants has been attracting public health attention as exposure can be related to contamination across air, water, and soil as well as associated with individual factors. This research uses Jefferson County, Kentucky, as an urban exposome case study to analyze sub-county metal concentrations in wastewater as a possible indicator of community toxicant exposure risk, and to test the feasibility of using wastewater to identify potential community areas of elevated metals exposure.

Auranofin targets UBA1 and enhances UBA1 activity by facilitating ubiquitin trans-thioesterification to E2 ubiquitin-conjugating enzymes.

UBA1 is the primary E1 ubiquitin-activating enzyme responsible for generation of activated ubiquitin required for ubiquitination, a process that regulates stability and function of numerous proteins. Decreased or insufficient ubiquitination can cause or drive aging and many diseases. Therefore, a small-molecule enhancing UBA1 activity could have broad therapeutic potential.

Infrared Reflection-Absorption Spectroscopy of α-Keto Acids at the Air-Water Interface: Effects of Chain Length and Headgroup on Environmentally Relevant Surfactant Films.

A variety of organic surfactants are found at air-water interfaces in natural environments, including on the surfaces of aqueous aerosols. The structure and morphology of these organic films can have profound impacts on material transfer between the gas and condensed phases, the optical properties of atmospheric aerosol, and chemical processing at air-water interfaces. Combined, these effects can have significant impacts on climate via radiative forcing, but our understanding of organic films at air-water interfaces is incomplete.
