INTRODUCTION: isolated left ventricular non-compaction (LVNC) is a heart disease with rather distinct morphologic and clinical manifestations. Available in the literature information about LVNC considering multiple left ventricle abnormal chords (LVAC) as one of its criterion motivated us to review the results obtained in the study of young patients with this pathology. The aim of the research was to demonstrate different clinical variants of left ventricular non-compaction course in adult patients and to clarify some pathogenetic aspects of this pathology...

BACKGROUND: The proportion of registered nurses (RNs) with employment in health-related positions before their initial RN education has increased in the past two decades. Previous research found that prior health-related employment is positively associated with RN workforce supply, potentially due to the wage differences based on different career paths. This study's objective is to test the hypotheses that prior health-related employment is associated with differences in starting wages and with different rates of wage growth for experience as an RN...

In this paper, we have introduced a general modeling approach for dynamic nonlinear systems that utilizes a variant of the simulated annealing algorithm for training the Laguerre-Volterra network (LVN) to overcome the local minima and convergence problems and employs a pruning technique to achieve sparse LVN representations with ℓ₁ regularization. We tested this new approach with computer simulated systems and extended it to autoregressive sparse LVN (ASLVN) model structures that are suitable for input-output modeling of nonlinear systems that exhibit transitions in dynamic states, such as the Hodgkin-Huxley (H-H) equations of neuronal firing...

OBJECTIVES: Patients treated with definitive chemoradiation for oropharyngeal squamous cell carcinoma (OPC) experience excellent outcomes but treatment toxicities remain significant. The adoption of intensity modulated radiation therapy (IMRT) reduced morbidity by allowing targeting of at risk areas while sparing uninvolved regions. We explored whether level V lymphatics (LVN) can be omitted from elective volumes in OPC. MATERIALS AND METHODS: This analysis included 408 patients treated for stage III/IV OPC with IMRT at our institution...

Registered nurses (RN) who held prior health-related employment in occupations other than licensed practical or vocational nursing (LPN/LVN) are reported to have increased rapidly in the past decades. Researchers examined whether prior health-related employment affects RN workforce supply. A cross-sectional bivariate probit model using the 2008 National Sample Survey of Registered Nurses was esti- mated. Prior health-related employment in relatively lower-wage occupations, such as allied health, clerk, or nursing aide, was positively associated with working s an RN...

According to our previous studies, stimulation of the red nucleus (RN) facilitates the low-threshold afferent-evoked jaw-opening reflex (L-JOR). It has been reported that the RN projects to the superior (SVN), lateral (LVN) and inferior vestibular (IVN) nuclei. The SVN and the LVN have reciprocal intrinsic connections with the medial vestibular nucleus (MVN). Our previous study demonstrated that stimulation of the vestibular nuclear complex (VN) modulates the L-JOR. These facts suggest that RN-induced facilitation of the L-JOR is mediated via the VN...

In resting state fMRI (rs-fMRI), only functional connectivity (FC) reductions in the default mode network (DMN) are normally reported as a biomarker for Alzheimer's disease (AD). In this investigation we have developed a comprehensive strategy to characterize the FC changes occurring in multiple networks and applied it in a pilot study of subjects with AD and Mild Cognitive Impairment (MCI), compared to healthy controls (HC). Resting state networks (RSNs) were studied in 14 AD (70 ± 6 years), 12 MCI (74 ± 6 years), and 16 HC (69 ± 5 years)...

AIMS: Lavender essential oil (Lvn) has been reported to have anti-inflammatory effects. Bronchial asthma is characterized by bronchial allergic inflammation with airway remodeling. Therefore, we evaluated the anti-inflammatory effect of Lvn on experimentally induced bronchial asthma in a murine model. MAIN METHODS: BALB/c mice were sensitized by an intraperitoneal injection of ovalbumin (OVA) at days 0 and 14, and subsequently challenged with nebulized OVA on days 28-30 (Control-Asthma group)...

Alternative paradigm for spatial and fibre-type selective vagus nerve stimulation (VNS) was developed using realistic structural topography and tested in an isolated segment of a porcine cervical left vagus nerve (LVN). A spiral cuff (cuff) containing a matrix of ninety-nine electrodes was developed for selective VNS. A quasitrapezoidal stimulating pulse (stimulus) was applied to the LVN via an appointed group of three electrodes (triplet). The triplet and stimulus were configured to predominantly stimulate the B-fibres, minimizing stimulation of the A-fibres and by-passing the stimulation of the C-fibres...

The axons of transected and re-apposed vestibulocochlear nerve of the frog, in contrast to mammalian species, regenerate and establish functional contacts within their original termination areas of the vestibular nuclear complex and the cerebellum. The lack of regenerative capability of the mammalian central nervous system (CNS) is partially attributed to various extracellular matrix (ECM) molecules, such as chondroitin sulfate proteoglycans (CSPG) and tenascin-R (TN-R), which exert inhibition on axon regeneration...

To provide safe and quality care to patients on hemodialysis, nephrology registered nurses must fully understand the roles of the healthcare providers to whom they delegate patient care. A job analysis survey of hemodialysis technicians and licensed practical nurses/licensed vocational nurses (LPNs/LVNs) was conducted by the Nephrology Nursing Certification Commission (NNCC) in 2011 to 1) revalidate the Certified Clinical Hemodialysis Technician (CCHT) test blueprint, 2) delineate differences in practice between entry-level technicians and experienced/advanced technicians, and 3) delineate differences in practice between hemodialysis technicians and LPNs/LVNs in hemodialysis settings...

The association between nursing home (NH) characteristics and residents' quality of life (QOL) has not been systematically reviewed. This study synthesizes published evidence about the association between NH ownership, affiliation, location, chain membership, percentage of private rooms, facility size, and staffing with residents' QOL. We searched Medline, Web of Science, CINAHL, and Scirus for primary studies published between 1960 and March 31, 2012. We critically appraised risk of bias according to study design, QOL measurements, and adjustment for residents' characteristics...

The peripheral auditory and vestibular systems are recognised to be closely related anatomically and physiologically; however, less well understood is the interaction of these two sensory systems in the brain. A number of previous studies in different species have reported that the dorsal and ventral cochlear nuclei receive direct projections from the primary vestibular nerve and one previous study had reported projections from the vestibular nucleus to the dorsal cochlear nucleus (DCN) in rabbit. Recently, Barker et al...

The vestibular system is classically associated with postural control, oculomotor reflexes and self-motion perception. The patients with vestibular loss are primarily concerned with balance and gait problems including head and trunk tilt and walking trajectory deviation to the lesioned side. These long-lasting postural and locomotor biases are thought to originate from changes in spatial perception of self. Indeed, we show here that vestibular cues are necessary for an accurate representation of body orientation...

The dorsal cochlear nucleus (DCN) is a first relay of the central auditory system as well as a site for integration of multimodal information. Vesicular glutamate transporters VGLUT-1 and VGLUT-2 selectively package glutamate into synaptic vesicles and are found to have different patterns of organization in the DCN. Whereas auditory nerve fibers predominantly co-label with VGLUT-1, somatosensory inputs predominantly co-label with VGLUT-2. Here, we used retrograde and anterograde transport of fluorescent conjugated dextran amine (DA) to demonstrate that the lateral vestibular nucleus (LVN) exhibits ipsilateral projections to both fusiform and deep layers of the rat DCN...
