Simulation of the electromagnetic response of the human body relies upon efficient computational models. The objective of this paper is to describe a new platform-independent and computationally-efficient full-body electromagnetic model, the Visible Human Project® (VHP)-Female v.3.0 and to outline its distinct features. We also report model performance results using two leading commercial electromagnetic antenna simulation packages: ANSYS HFSS and CST MICROWAVE STUDIO®.

The Cluster-Span Threshold (CST) is a recently introduced unbiased threshold for functional connectivity networks. This binarisation technique offers a natural trade-off of sparsity and density of information by balancing the ratio of closed to open triples in the network topology. Here we present findings comparing it with the Union of Shortest Paths (USP), another recently proposed objective method. We analyse standard network metrics of binarised networks for sensitivity to clinical Alzheimer's disease in the Beta band of Electroencephalogram activity...

To generate voluntary forearm movements, the information that is encoded in the activity of the cortical neurons has to travel through the spinal cord and activate the skeletal muscles. The axons carrying these signals are tightly bundled together in the descending tracts that control the spinal circuitry innervating the forearm muscles. In this paper, we show that corticospinal tract (CST) signals can be used to predict forearm electromyographic (EMG) activities that are recorded during an isometric-pull task...

AIM: To maintain oral intake in elderly patients with dementia, it is important to evaluate their oral function. However, these patients often have difficulties following instructions during oral function tests, especially with the progression of dementia. The task of sucking a lollipop candy is simple for elderly patients with mild or severe dementia. The present study aimed to develop a new oral function test - the "candy sucking test" (CST) - for elderly patients with dementia. METHODS: We recruited 23 female elderly patients with dementia (mean age 89...

BACKGROUND: Cognitive stimulation therapy (CST) is a psychosocial group-based intervention for dementia shown to improve cognition and quality of life with a similar efficacy to cholinesterase inhibitors. Since CST can be delivered by non-specialist healthcare workers, it has potential for use in low-resource environments, such as sub-Saharan Africa (SSA). We aimed to assess the feasibility and clinical effectiveness of CST in rural Tanzania using a stepped-wedge design. METHODS: Participants and their carers were recruited through a community dementia screening program...

PURPOSE: Modern cataract surgery is generally considered to bring about modest and sustained intraocular pressure (IOP) reduction. However, the pathophysiological mechanism for this remains unclear. Moreover, a change in ocular biomechanical properties after surgery can affect the measurement of IOP. The aim of the study is to investigate ocular biomechanics, before and following cataract surgery, using Corvis ST tonometry (CST). PATIENTS AND METHODS: Fifty-nine eyes of 59 patients with cataract were analyzed...

BACKGROUND: Intraoperative electrophysiology is increasingly used for various lesion resections, both in adult and pediatric brain surgery. Subcortical mapping is often used in adult surgery when lesions lie in proximity to the corticospinal tract (CST). We describe a novel technique of continuous subcortical mapping using an electrified Cavitron UltraSonic Aspirator (CUSA) in children with supratentorial lesions. METHODS: We evaluated the method of subcortical mapping using a CUSA as a stimulation probe...

BACKGROUND: Chromogranin A (CgA) levels have previously been found to predict mortality in heart failure (HF), but currently no information is available regarding CgA processing in HF and whether the CgA fragment catestatin (CST) may directly influence cardiomyocyte function. METHODS AND RESULTS: CgA processing was characterized in postinfarction HF mice and in patients with acute HF, and the functional role of CST was explored in experimental models. Myocardial biopsies from HF, but not sham-operated mice, demonstrated high molecular weight CgA bands...

Identifying the temporal progression of a set of biological samples is crucial for comprehending the dynamics of the underlying molecular interactions. It is often also a basic step in data denoising and synchronization. Finally, identifying the progression order is crucial for problems like cell lineage identification, disease progression, tumor classification, and epidemiology and thus impacts the spectrum of disciplines spanning basic biology, drug discovery, and public health. Current methods that attempt solving this problem face difficulty when it is necessary to factor-in complex relationships within the data such as grouping, partial ordering or bifurcating or multifurcating progressions...

Some microstructure parameters, such as permeability, remain elusive because mathematical models that express their relationship to the MR signal accurately are intractable. Here, we propose to use computational models learned from simulations to estimate these parameters. We demonstrate the approach in an example which estimates water residence time in brain white matter. The residence time τi of water inside axons is a potentially important biomarker for white matter pathologies of the human central nervous system, as myelin damage is hypothesised to affect axonal permeability, and thus τi...

#12
Lauren Kois, James M Wellbeloved-Stone, Preeti Chauhan, Janet I Warren
Combined evaluations of competency to stand trial (CST; competency) and mental state at the time of the offense (MSO; sanity) frequently co-occur. However, most research examines the 2 as discrete constructs without considering 4 potential combined evaluation outcomes: competent-sane, incompetent-sane, competent-insane, and incompetent-insane. External validity can be improved if research more closely mirrored practice. It may be incorrect to assume incompetent defendants are similar across CST-only and combined evaluations, and insane defendants are similar across MSO-only and combined evaluations...

Shohag Barman, Yung-Keun Kwon
BACKGROUND: Inferring a gene regulatory network from time-series gene expression data in systems biology is a challenging problem. Many methods have been suggested, most of which have a scalability limitation due to the combinatorial cost of searching a regulatory set of genes. In addition, they have focused on the accurate inference of a network structure only. Therefore, there is a pressing need to develop a network inference method to search regulatory genes efficiently and to predict the network dynamics accurately...

Combination antimicrobial therapy is an important option in the fight against Gram-negative 'superbugs'. This study systematically investigated the synergistic effect of colistin (CST) and chloramphenicol (CHL) in combination against extensively drug-resistant Acinetobacter baumannii (XDR-AB). The microtitre plate chequerboard assay was used to test synergy against 50 XDR-AB clinical strains. Then, three XDR-AB clinical isolates and the type strain A. baumannii ATCC 19606 were chosen for further synergy studies using time-kill assay, mutant prevention concentration (MPC) assay and real-time population analysis profile (PAP) assay...

This study characterizes antibiotic mycelial residue (AMR) dewaterability with microwave (MW) treatment. Capillary suction time (CST) and the water content (WC) of AMR cake were used to evaluate AMR dewaterability. A thermogravimetric analysis and investigation of changes in AMR physical characteristics (e.g., extracellular polymeric substances (EPS) and particle size) were conducted to interpret AMR dewaterability variations. The results indicate that MW irradiation heavily influences the release of polymers and AMR particle size, which are significantly related to AMR dewaterability, e...

: 29 Background: Good communication is crucial to good patient care. Gynecologic oncology providers often face challenging communication scenarios, including giving serious news and discussing goals of care. Communication skills training (CST) has been shown to improve skill acquisition among providers of multiple specialties, but it has not been described in providers from gynecologic oncology or any surgical oncology specialty. METHODS: We conducted a two-day CST workshop, based on the VitalTalk© model, with four faculty members (2 gynecologic oncologists and 2 palliative care physicians) and 10 gynecologic oncology provider participants (5 fellows and 5 advanced practice providers)...
