The wettability of graphene on various substrates has been intensively investigated for practical applications including surgical and medical tools, textiles, water harvesting, self-cleaning, oil spill removal and microfluidic devices. However, most previous studies have been limited to investigating the intrinsic and passive wettability of graphene and graphene hybrid composites. Here, we report the electrowetting of graphene-coated metal meshes for use as electroactive flow control devices, utilizing two antagonistic functions, hydrophobic repellency versus liquid permeability...

Different metallic materials have different polarization characteristics as dictated by the open circuit potential, breakdown potential, and passivation potential of the material. The detection of these electrochemical parameters identifies the corrosion factors of a material. A reliable and well-functioning corrosion system is required to achieve this. Corrosion of the samples was achieved via a potentiodynamic polarization technique employing a three-electrode configuration, consisting of reference, counter, and working electrodes...

BACKGROUND: A part of damage-control laparotomy is to leave the fascial edges and the skin open to avoid abdominal compartment syndrome and allow further explorations. This condition, known as open abdomen (OA), although effective, is associated with severe complications. Our aim was to develop evidence-based recommendations to define indications for OA, techniques for temporary abdominal closure, management of enteric fistulas, and methods of definitive wall closure. METHODS: The literature from 1990 to 2014 was systematically screened according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-analyses] protocol...

There are many advantages of direct nose-to-brain drug delivery in the treatment of neurological disorders. However, its application is limited by the extremely low delivery efficiency (< 1%) to the olfactory mucosa that directly connects the brain. It is crucial to develop novel techniques to deliver neurological medications more effectively to the olfactory region. The objective of this study is to develop a numerical platform to simulate and improve intranasal olfactory drug delivery. A coupled image-CFD method was presented that synthetized the image-based model development, quality meshing, fluid simulation, and magnetic particle tracking...

BACKGROUND: Historically, Actinomyces infection has been associated primarily with the intrauterine device. Recently, case reports associating Actinomyces with other implants have been described, including nonwoven polypropylene mesh used for urethral slings and Mersilene cerclage placements. However, there are no reported cases of chronic Actinomyces infections associated with retained Mersilene cerclage. CASE: A 51-year-old woman, gravida 3, para 3, presented with a 10-year history of vaginal discharge and Actinomyces identified on endometrial biopsy...

The dissemination of information online and resultant public discourse through social media and other online channels has influenced the practice of medicine in dramatic ways. Physicians have historically worked to develop new techniques and devices for the benefit of their patients. It is only a more recent phenomenon, however, that these tools are either removed or their use is curtailed largely driven by anecdotal reports; passionate, vocal, often media-savvy advocates; and plaintiff attorneys. The use of power morcellation, hysteroscopic tubal sterilization, and mesh in urogynecologic procedures all have been victims of these societal pressures...

BACKGROUND: Many patients experience difficulties adhering to medication regimes. For people who forget or get confused about medication, there are products to help them such as multi-compartment medication devices (MMDs). Some of these, known as electronic MMDs (eMMDs), use audible and/or visual signals to prompt the patient when to take medication, dispense medications, give instructions to the patient, and contact a caregiver (mobile Internet or text to a carer) as needed. AIM: To systematically review the literature on the use of eMMDs, to determine what evidence for their effectiveness is available...

Pelvic organ prolapse (POP) is a common problem that negatively impacts women's quality of life. A variety of surgeries exist for POP treatment, including procedures performed with and without mesh augmentation. The growing use of mesh in prolapse surgeries in the 2000s was associated with increasing reports of complications, resulting in Food and Drug Administration (FDA) Safety Notifications, and in 2012, the FDA ordered transvaginal mesh manufacturers to conduct prospective studies to evaluate longer-term outcomes...

UNLABELLED: Surgical meshes are widely used in clinics to reinforce soft tissue's defects, and to give support to prolapsed organs. However, the implantation of surgical meshes is commonly related with an inflammatory response being difficult to eradicate without removing the mesh. Here we hypothesize that the combined use of surgical meshes and mesenchymal stem cells (MSCs) could be a useful tool to reduce the inflammatory reaction secondary to mesh implantation. In vitro determinations of viability, metabolic activity and immunomodulation assays were performed on MSCs-coated meshes...
