Light-emitting electrochemical cells (LECs) show high technical potential for display and lighting utilizations owing to the superior properties of solution processability, low operation voltage, and employing inert cathodes. For maximizing the device efficiency, three approaches including development of efficient emissive materials, optimizing the carrier balance, and maximizing the light extraction have been reported. However, most reported works focused on only one of the three optimization approaches. In this work, a combinational approach is demonstrated to optimize the device efficiency of LECs. A sophisticatedly designed yellow complex exhibiting a superior steric hindrance and a good carrier balance is proposed as the emissive material of light-emitting electrochemical cells and thus the external quantum efficiency (EQE) is up to 13.6%. With an improved carrier balance and reduced self-quenching by employing the host-guest strategy, the device EQE can be enhanced to 16.9%. Finally, a diffusive layer embedded between the glass substrate and the indium-tin-oxide layer is utilized to scatter the light trapped in the layered device structure, and consequently, a high EQE of 23.7% can be obtained. Such an EQE is impressive and consequently proves that the proposed combinational approach including adopting efficient emissive materials, optimizing the carrier balance, and maximizing the light extraction is effective in realizing highly efficient LECs.Developing efficient non-precious-metal catalysts to accelerate the sluggish oxygen reduction reaction (ORR) is highly desired but remains a great challenge. Herein, using 2D bimetallic Zn/Fe-MOF as the precursor and g-C3N4 as the nitrogen source and stabilizer, porous carbon nanosheets doped with large amounts of single/paired Fe atoms (3.89 wt %) and N (10.28 wt %) are successfully prepared. It is found that the addition of g-C3N4 plays a key role in achieving a high loading of Fe single/paired atoms, and the 2D nanosheet structure gives the materials a high surface area and highly porous structure, resulting in outstanding ORR catalytic activity in both alkaline and acidic solutions. Our optimal sample achieved half-wave potentials in alkaline and acid media of up to 0.86 and 0.79 V (vs reversible hydrogen electrode (RHE)), respectively, values 20 mV higher than a commercial Pt/C catalyst in an alkaline medium and only 60 mV lower than Pt/C in an acidic medium. Moreover, its ORR durability was superior to that of commercial Pt/C in both electrolytes. We found that almost all the doped Fe in the sample existed as single or paired atoms coordinated with N. This work may provide an effective strategy for preparing high-performance catalysts bearing single/paired atoms by using MOFs as precursors.Ejaculatory duct obstruction is a rare condition identified in up to 5% of infertile men. Patients with ejaculatory duct obstruction can present with aspermia, azoospermia or oligoasthenospermia, painful ejaculation, hematospermia, prostatic pain, or male infertility. Semen analysis, transrectal ultrasonography, pelvic computerized tomography and magnetic resonance imaging are often used in the diagnostic work up, but with limited accuracy. While transurethral resection of the ejaculatory ducts has good efficacy for distal duct obstruction, results for proximal obstruction are less impressive, and it might cause severe complications, such as rectal injury and urinary incontinence. Recently, the use of high quality endourological devices and an improved understanding of ejaculatory ducts anatomy gleaned through the use of sophisticated imaging tools have led to the development of novel minimally invasive treatment options for this condition. The present study aims to report an index case of ejaculatory ducts obstruction managed with seminal vesiculoscopy, and review the current literature regarding this topic.Intralesional corticosteroids are associated with various, uncommon, local adverse events [1]. Atrophy and hypopigmentation most commonlyremain localized to sites of injection. However, outward radiation in a linear, streaky pattern has been reported and is termed "perilesional/perilymphatic hypopigmentation or atrophy [2]." We report a case of this rare adverse event.Online coupon retailers and pharmacies are popular sites that patients can access discounted medications when compared to cash prices. These sources are especially important for those patients without insurance. In our study, we analyzed commonly prescribed topical and oral medications and compared the cash prices to the discounted medications based on a typical month of usage. We found savings in every one of the medications that we analyzed, some with savings up to hundreds of dollars. Savings were present in all the sources analyzed, with the coupon-based programs often having the lowest price. We suggest certain alternative prescribing guidelines when considering patients who may not be able to afford cash prices of medications. Our hopes with this study are to quantify savings for discounted medications as well as to help physicians target more affordable medications for their patients.Pyoderma gangrenosum is a rare autoinflammatory skin disease. Treatment is multifactorial, addressing inflammation, pain, underlying disease, if present, and the wound. Gentian violet has been used for hundreds of years in a variety of dermatologic conditions for its anti-inflammatory properties. This study aims to evaluate gentian violet in wound healing for pyoderma gangrenosum. A-1331852 nmr We conducted a retrospective chart review of patients with pyoderma gangrenosum treated with gentian violet at the Wake Forest School of Medicine Department of Dermatology in the last 10 years. The primary outcome was clinical improvement. Of the 34 cases that met inclusion criteria, 70% improved with gentian violet, 24% had no documented change, 3% initially improved then worsened, and 3% had unclear results. Gentian violet is a safe and cheap treatment that may improve resolution of pyoderma gangrenosum lesions in addition to systemic therapy.Sox10 immunostaining is used for the diagnosis and margin evaluation of melanocytic lesions. Sox10 was initially thought not to stain fibrohistiocytic processes. Consequently, it was believed to reliably distinguish desmoplastic melanoma from scar. However, recent data from formalin sections suggest Sox10 is less specific than previously thought. In this report, we demonstrate that Sox10-stained Mohs sections commonly show strong, fractional staining of scar. When using Sox10 with frozen section immunohistochemistry, Mohs practitioners should recognize the potential of this marker to stain scar to avoid overdiagnosis of desmoplastic melanoma.
