To date, numerical simulations of the brain tissue have been limited by their lack of realism and flexibility. The purpose of this work is to propose a controlled and flexible generative model for brain cell morphology and an efficient computational pipeline for the reliable and robust simulation of realistic cellular structures with application to numerical simulation of intra-cellular diffusion-weighted MR (DW-MR) signal features. Inspired by the advances in computational neuroscience for modelling brain cells, we propose a generative model that enables users to simulate molecular diffusion within realistic digital brain cells, such as neurons, in a completely controlled and flexible fashion.

Objective: to evaluate the association of ulnar artery occlusion (UAO) assessed by Doppler Ultrasonography (dUS) with the severity markers of systemic sclerosis (SSc) METHODS: 204 unselected patients fulfilling 2013 ACR/EULAR classification criteria for SSc were included in this cross-sectional multicenter study. All patients benefit from bilateral hand dUS evaluating the presence of UAO and clinical/paraclinical visceral evaluation according to current guidelines. Univariable and multivariable ordinal regression models were conducted, grading the severity of UAO as "no UAO", "only one UAO" and "UAO on both hands" and assessing its association with clinical features of SSc.

Resistive RAM crossbar arrays offer an attractive solution to minimize off-chip data transfer and parallelize on-chip computations for neural networks. Here, we report a hardware/software co-design approach based on low energy subquantum conductive bridging RAM (CBRAM®) devices and a network pruning technique to reduce network level energy consumption. First, we demonstrate low energy subquantum CBRAM devices exhibiting gradual switching characteristics important for implementing weight updates in hardware during unsupervised learning. Read More

Introduction: The rising popularity of social media, since their inception around 20 years ago, has been echoed in the growth of health-related research using data derived from them. This has created a demand for literature reviews to synthesise this emerging evidence base and inform future activities. Existing reviews tend to be narrow in scope, with limited consideration of the different types of data, analytical methods and ethical issues involved. Read More

Background: Early detection of Atrial Fibrillation (AF) is a public health priority across the globe because AF-related strokes are preventable. Despite an ongoing stroke epidemic in India, a public health strategy for AF screening and treatment is missing because the epidemiology of AF in India remains poorly defined.
Methods: This population-based study used mobile technology to derive age and sex-stratified AF prevalence by screening 7 participants in each of six age and sex strata (age 40-55, 56-65, 65+, and male and female) from 50 villages (2100 participants). Read More

Citizen-collected arthropod vectors are useful for epidemiological studies of vector-borne disease, especially since the vectors encountered by the public are the subset of vectors in nature that have a disproportionate impact on health. Programs integrating educational efforts with collecting efforts may be particularly effective for public health initiatives, resulting in an empowered public with knowledge of vector-borne disease prevention. Citizen science programs have been successfully implemented for the collection of unprecedented sample sets of mosquitos, ticks, and triatomines. Read More

Circulating tumor cells (CTCs) are rare cells shed into the bloodstream by invasive tumors and their analysis offers a promising noninvasive tool to predict and monitor therapeutic responses. CTCs can be isolated from patient blood and their characterization at single-cell level can inform on the genomic landscape of a tumor. All CTC enrichment methods bear a burden of contaminating normal cells, which mandate a further step of purification to enable reliable downstream genetic analysis. Read More

A major effort has been focused on the detection of oncogenes' mutations in diverse types of clinical specimens including formalin-fixed and paraffin embedded tissues, presently the gold-standard samples, up to plasma, that constitute a noninvasive alternative source of tumor DNA. The reliable detection of mutations in circulating tumor DNA requires a high analytical sensitivity. Here, we applied three different highly sensitive methodologies (COLD-PCR, a microarray-based approach and the droplet digital PCR, ddPCR) to identify mutations in the plasma of 30 metastatic colorectal cancer patients previously genotyped on tissue biopsy.

Although mechanisms of acquired resistance to 1st and 3rd generation EGFR-TKI continue to be elucidated, there have been few clinical investigations into the mechanisms of acquired resistance to the 2nd generation EGFR-TKI afatinib. We analyzed data from 20 patients with advanced lung adenocarcinoma who acquired resistance to afatinib, including resistance during EGFR-TKI re-challenge. We examined EGFR T790M and C797S mutations, BRAF V600E mutation, and MET amplification with the MBP-QP method and with droplet digital PCR using ctDNA and re-biopsy samples obtained before and after afatinib treatment.

The size distribution of manufactured sand particles has a significant influence on the quality of concrete. To overcome the shortcomings of the traditional vibration-sieving method, a manufactured sand casting/dispersing system was developed, based on the characteristics of the sand particle contours (as determined by backlit image acquisition) and an extraction mechanism. Algorithms for eliminating particles from the image that had be repeatedly captured, as well as for identifying incomplete particles at the boundaries of the image, granular contour segmentation, and the determination of an equivalent particle size, are studied.

Objective: To use digital histology in a large autopsy cohort of Lewy Body Disorder (LBD) patients with dementia to test the hypotheses that co-occurring Alzheimer's disease (AD) pathology impacts the anatomic distribution of α-synuclein (SYN) pathology and that co-occurring neocortical tau pathology in LBD associates with worse cognitive performance and occurs in a pattern differing from AD.
Methods: Fifty-five autopsy-confirmed LBD (PDD: 36, DLB:19) patients and 25 AD patients were studied. LBD patients were categorized as having moderate/severe AD co-pathology (SYN+AD=20) or little/no AD co-pathology (SYN-AD=35). Read More

Purpose: In many medical schools, the study of Anatomy is becoming increasingly theoretical owing to the difficulty of having human body parts available, rather than offering the students the possibility of a more realistic and practical approach. We developed a project where we use a 3D printer to produce models of the human skull bones, with high quality and quantity to satisfy the needs for Anatomy classes and to be available for request to study at home.
Methods: We selected regular and well-shaped bones of the head upon which we based the 3D models. Read More

There is a growing recognition within cognitive enhancement and neuroethics debates of the need for greater emphasis on cognitive artefacts. This paper aims to contribute to this broadening and expansion of the cognitive-enhancement and neuroethics debates by focusing on a particular form of relation or coupling between humans and cognitive artefacts: interaction-dominance. We argue that interaction-dominance as an emergent property of some human-cognitive artefact relations has important implications for understanding the attribution and distribution of causal and other forms of responsibility as well as agency relating to the actions of human-cognitive artefact couplings.
