#1
Sebastian Hoth, Oliver Christian Dziemba
: Auditory evoked potentials (AEP) are highly demanded during the whole process of equipping patients with cochlear implants (CI). They play an essential role in preoperative diagnostics, intraoperative testing, and postoperative monitoring of auditory performance and success. The versatility of AEP's is essentially enhanced by their property to be evokable by acoustic as well as electric stimuli. Thus, the electric responses of the auditory system following acoustic stimulation and recorded by the conventional surface technique as well as by transtympanic derivation from the promontory (Electrocochleography [ECochG]) are used for the quantitative determination of hearing loss and, additionally, electrically evoked compound actions potentials (ECAP) can be recorded with the intracochlear electrodes of the implant just adjacent to the stimulation electrode to check the functional integrity of the device and its coupling to the auditory system...

Shukei Sugita, Takeo Matsumoto
Although elucidation of the mechanism of aortic aneurysm rupture is important, the characteristics of crack initiation and propagation sites remain unknown. To determine the microscopic properties of these sites, the characteristics of local strains and constituents at crack initiation and propagation sites were investigated during biaxial stretching of porcine thoracic aortas (PTAs). PTAs were sliced into approximately 50-[Formula: see text]-thick sections, and the center of the sections was made especially thin using our previously developed technique...

BACKGROUND: The World Health Organization has identified developing the knowledge and skills of healthcare professionals who are involved in dementia care as a priority. Most healthcare professionals lack the necessary knowledge, skills and understanding to provide high quality dementia care. While dementia education amongst most UK university health and social care programmes is inconsistent, we know little about the provision of dementia education in European universities. OBJECTIVES: To examine the provision of accredited higher education on dementia in European countries, to illustrate that it is highly variable despite universities being the major provider of education for healthcare professionals internationally...

High thermal conductive nanofibrillated cellulose (NFC) hybrid films based on nanodiamond (ND) were fabricated by a facile vacuum filtration technique. In this issue, the thermal conductivity (TC) on the in-plane direction of the NFC/ND hybrid film had a significant enhancement of 775.2% at a comparatively low ND content (0.5 wt %). The NFC not only helps ND to disperse in the aqueous medium stably but also plays a positive role in the formation of the hierarchical structure. ND could form a thermal conductive pathway in the hierarchical structures under the intermolecular hydrogen bonds...

PURPOSE OF REVIEW: Clinical islet transplantation does not enjoy the success seen for solid organ transplants, indicating a need for new therapeutic approaches to improve patient outcomes. This has prompted investigation into islet autonomous factors and pathways that may represent druggable targets. These have the potential to synergize with approaches aimed at generating graft-specific tolerance. RECENT FINDINGS: There are emerging data that nuclear factor κB (NF-κB) activation can prevent and or overcome tolerance, whereas dampening NF-κB activation in immune cells is associated with prolonged allograft survival...

BACKGROUND: The lower limb muscle may play an important role in decreasing the heart's pumping workload. Aging and inactivity cause atrophy and weakness of the muscle, leading to a loss of the heart-assisting role. An electrical lower limb muscle stimulator can prevent atrophy and weakness more effectively than conventional resistance training; however, it has been reported to increase the heart's pumping workload in some situations. Therefore, more effective tools should be developed...

As far back as the eighteenth and early nineteenth centuries, microbial infections were responsible for vast numbers of deaths. The trend reversed with the introduction of antibiotics coinciding with longer life. Increased life expectancy however, accompanied the emergence of age related chronic inflammatory states including the sporadic form of Alzheimer's disease (AD). Taken together, the true challenge of retaining health into later years of life now appears to lie in delaying and/or preventing the progression of chronic inflammatory diseases, through identifying and influencing modifiable risk factors...

High-throughput sequencing metabarcoding studies in marine biosecurity have largely focused on targeting environmental DNA (eDNA). DNA can persist extracellularly in the environment, making discrimination of living organisms difficult. In this study, bilge water samples (i.e., water accumulating on-board a vessel during transit) were collected from 15 small recreational and commercial vessels. eDNA and eRNA molecules were co-extracted and the V4 region of the 18S ribosomal RNA gene targeted for metabarcoding...

Gedankenexperiments have consistently played a major role in the development of quantum theory. A paradigmatic example is Wheeler's delayed-choice experiment, a wave-particle duality test that cannot be fully understood using only classical concepts. We implement Wheeler's idea along a satellite-ground interferometer that extends for thousands of kilometers in space. We exploit temporal and polarization degrees of freedom of photons reflected by a fast-moving satellite equipped with retroreflecting mirrors...

Making music at the highest international standards can be rewarding, but it is also challenging, with research highlighting pernicious ways in which practicing and performing can affect performers' health and wellbeing. Several studies indicate that music students' perceptions, attitudes, and behaviors toward health and healthy living are less than optimal, especially considering the multiple physical and psychological demands of their day-to-day work. This article presents the results of a comprehensive screening protocol that investigated lifestyle and health-related attitudes and behaviors among 483 undergraduate and postgraduate students (mean age = 21...

Obstructive sleep apnea (OSA) is one of the most common sleep disorders, especially in elderly population. Despite its high prevalence and severe consequences, most patients remain undiagnosed due to serious limitations on the existing equipment. Efforts are being done to find cost-effective alternatives and mHealth solutions could play a key role. One promising approach in this context is the acoustic analysis of snoring. The sensor it requires is a microphone, which is widely available in different models and even integrated in smartphones...

Estimation of breathing rate (BR) along with electrocardiogram signal plays an important role in patient health monitoring. Continuous monitoring of BR is often required during diagnosis of many diseases. Traditional methods like nasal air flow equipments employ cumbersome methods of BR monitoring which is not suitable for continuous monitoring. Therefore, a non-invasive method of estimation is required. This paper proposes a non-invasive way of BR estimation using dry-electrode ECG from the palm of a person...

In mechanical ventilation, in particular when neonates are ventilated, it is crucial to accurately control the amount of the gas delivered to the patients. Mechanical ventilators are equipped with one of more flowmeters. The signal of the flowmeter is used as feedback to control the amount of gas delivered to the patients. Therefore, the accuracy of the flowmeter plays a crucial role in the accurate adjustment of the gas amount delivered by the ventilator. Among several solutions, variable area orifice meters (VAOMs) have several valuable features (e...

REVIEW
Shelly Hen-Avivi, Roi Avraham
Despite the availability of antibiotics and immunization, infectious diseases remain a major cause of malignancy and death worldwide. Yet, it is well documented that for most infectious agents, clinical disease develops in only a small minority of infected individuals. There is, in fact, great heterogeneity in infection outcome, from complete clearance of the pathogen to severe illness. Understanding this variation remains elusive, despite its great potential to equip us with new tools for the treatment of infectious diseases...
