A new fiber pressure sensor is proposed and analyzed in this paper. A commercial arc fusion splicer and pressure-assisted arc discharge technology are used here to fabricate a silica hollow microbubble from a common glass tube with the characteristics of a thin film. Then the single mode fiber is embedded into the microbubble to form a fiber Fabry-Perot interferometer by measuring the reflected interference spectrum from the fiber tip and microbubble end. As the wall thickness of the micro-bubble can reach up to several micrometers, it can then be used for measuring the outer pressure with high sensitivity...

Right ventricular failure (RVF) after cardiac transplant (CTX) or implantation of a continuous-flow left ventricular assist device (CF-LVAD) is associated with significant post-operative morbidity and mortality. A variety of modalities have been used to treat post-operative RVF, including management of volume status, intravenous inotropes and vasodilators, and right-sided mechanical support. Inhaled vasodilator agents are a unique treatment option aimed at minimizing systemic absorption by delivering therapy directly to the pulmonary vasculature...

Children with a variety of diagnoses have impairments that limit their arm function. Despite the fact that arm function is important for early learning and activities of daily living, there are few tools to assist movement for these children, and existing devices have challenges related to cost, accessibility, comfort, and aesthetics. In this article, we describe the design process and development of the first garment-based exoskeleton to assist arm movement in young children with movement impairments: the Playskin Lift(TM)...

Cancer is a growing health problem worldwide. Common treatments include surgery, chemotherapy and radiation therapy. Systemic anti-cancer medications often result in an array of physical and psychological side effects. Supportive care assists patients with cancer in managing multidimensional symptoms that result from treatment or the illness itself. This review discusses supportive care and examines patient counselling and mind-diversion activities, which are safe and cost-effective strategies. Improving cancer patients' health and wellbeing should be encouraged in oncology nursing practice and by teaching students the knowledge and skills needed to provide supportive care...

RESUMEN Diseases like diabetes mellitus (DM) and hypertension (HT) generate high costs and are the most common cause of mortality in the Americas. In the case of Peru, given demographic and epidemiological changes, particularly the alarming increase in overweight and obesity, the burden of these diseases is constantly increasing, resulting in the need to budget more financial resources to the health services. The total care costs of these diseases and their complications represent a financial burden that should be considered very carefully by health institutions when they draft their budgets...

It is still a challenging issue to design earth-abundant electrocatalysts with low cost, high activity and long-term stability for the hydrogen evolution reaction (HER) based on water splitting in alkaline solutions. Here, we report a facile synthetic route for a three-dimensional, porous Ni/Ni3S2 nano-network on carbon cloth for the efficient catalysis of HER. This unique structure exposes a high proportion of Ni/Ni3S2 hetero-interfaces to the electrolyte, creating a synergetic effect between Ni and Ni3S2 that enhances HER...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by airflow obstruction due to an abnormal inflammatory response of the lungs to noxious particles or gases, for example, cigarette smoke. The pattern of care for people with moderate to very severe COPD often involves regular lengthy hospital admissions, which result in high healthcare costs and an undesirable effect on quality of life. Research over the past decade has focused on innovative methods for developing enabling and assistive technologies that facilitate patient self-management...

In see-through systems an observer watches a (background) scene partially occluded by a display. In this display, usually positioned close to the observer, a region of the background scene is shown, yielding the sensation that the display is transparent. To achieve the transparency effect, it is very important to compensate the parallax error and other distortions caused by the image acquisition system. In this paper a detailed study of a video see-through methodology with parallax correction is performed. In a system composed by two cameras - one directed to the user and another to the background scene - and a display, the relative position between the user, the display and the scene is estimated using a feature detection algorithm and the parallax error is compensated assuming a planar scene model...

Laparoscopy has become the standard surgery mode of right hemicolectomy, including conventional laparoscopy, hand-assisted laparoscopic surgery (HALS), single-port laparoscopic surgery (SPLS), natural orifices translumenal endoscopic surgery (NOTES) and robotic laparoscopy. How to select reasonable laparoscopic mode could be confusing sometimes. For patients, safety, cost-effectiveness and radical cure of the surgery are very important. For doctors, advance and convenience of the surgery must be considered as well...

A fast, simple and sustainable method based on choline chloride-urea deep eutectic solvent (known as Reline) was employed to synthesize nanosized fluorapatite (FA) particles. Using XRD, FESEM, TEM, EDS, and FTIR, the formation of FA nanoparticles with average crystal size of ~34nm, percent crystallinity of 93%, particle size of ~45nm, and high crystal, elemental, and structural purity was confirmed. The MTT cytotoxicity assay endorsed the non-toxicity of as-synthesized FA nanoparticles. The good biocompatibility, osteogenity and mineralization ability of as-synthesized FA nanoparticles were confirmed by Alizarin red staining, Acridine orange staining and ALP activity tests...

Two-dimensional thin Bi₂WO₆ nanoplates have been fabricated using a cetyltrimethylammonium bromide (CTAB)-assisted hydrothermal method. We investigated the proposed formation mechanism based on the crystalline structures of the thin Bi₂WO₆ nanoplates. The high adsorption ability and excellent visible-light driven photocatalytic activities of the Bi₂WO₆ nanoplates were illustrated, in view of exposed (001) facets of nanoplates possessing faster separation of photo-generated charge carriers and increased catalytically active sites...
