Importance: Acute zonal occult outer retinopathy (AZOOR) remains a challenging diagnosis. Early recognition of the disease depends on advances in imaging modalities that can improve phenotyping and contribute to the understanding of the underlying pathogenesis. Objectives: To expand the range of approaches available to assist in the identification of AZOOR by multimodal imaging and to analyze the fundus lesions by quantifying short-wavelength fundus autofluorescence (quantitative fundus autofluorescence [qAF]) and spectral-domain optical coherence tomography...

Combining the electrophoresis and conventional Coulter methods, we previously proposed the electrophoretic Coulter method (ECM), enabling simultaneous analysis of the size, number, and zeta potential of individual specimens. We validated the ECM experimentally using standard polystyrene particles and red blood cells (RBCs) from sheep; the latter was the first ECM application to biological particles in biotechnology research. However, specimens are prevented from passing through the ECM module aperture, which prevents accurate determination of the zeta potential of each specimen...

Medullary thyroid carcinoma (MTC) in multiple endocrine neoplasia type 2 (MEN2) is an autosomal dominant disorder caused by the mutation of the RET proto-oncogene, that shows nearly complete penetration. The American Thyroid Association guidelines recommend prophylactic thyroidectomy for patients with high-risk RET mutations. However, in Japan, ethical and medical issues may preclude prophylactic treatment in young patients. Hence, an early diagnosis of MTC is necessary to ensure a favorable outcome. Here, we report the case of a young Japanese girl with a high-risk RET mutation, diagnosed with very early stage MTC using serum calcitonin (Ctn) values measured using an electro chemiluminescence immuno-assay (ECLIA)...

The concept of epilepsy syndromes, introduced in 1989, was defined as "clusters of signs and symptoms customarily occurring together". Definition of epilepsy syndromes based on electro-clinical features facilitated clinical practice and, whenever possible, clinical research in homogeneous groups of patients with epilepsies. Progress in the fields of neuroimaging and genetics made it rapidly clear that, although crucial, the electro-clinical description of epilepsy syndromes was not sufficient to allow much needed development of targeted therapies and a better understanding of the underlying pathophysiological mechanisms of seizures...

Quadrilateral space syndrome (QSS) is a rare orthopedic condition caused by compression, entrapment, or injury to the axillary nerve or posterior humeral circumflex artery as they arise from the quadrilateral space. QSS can present with point tenderness over the quadrilateral space and weakness and paresthesia in the axillary nerve distribution. It is commonly associated with repetitive overhead activities and is seen in athletes engaging in such activities. Here we report a case of QSS in a 42-year-old male weight lifter who presented with pain and soreness in the posterior aspect of his right shoulder radiating around his arm as well as slight weakness of his right shoulder of a few weeks duration...

The monitoring of biomolecular interactions is a key requirement for the study of complex biological processes and the diagnosis of disease. Technologies that are capable of providing label-free, real-time insight into these interactions are of great value for the scientific and clinical communities. Greater understanding of biomolecular interactions alongside increased detection accuracy can be achieved using technology that can provide parallel information about multiple parameters of a single biomolecular process...

Atrial flutter (AFlu) is usually a fast (>240 bpm) and regular right atrial macroreentrant tachycardia, with a constrained critical region of the reentry circuit located at the cavotricuspid isthmus (CTI; typical CTI-dependent AFlu). However, a variety of right and left atrial tachycardias, resulting from different mechanisms, can also present as AFlu (atypical non-CTI-dependent AFlu). The electrocardiogram can provide clues to its origin and location; however, additional entrainment and more sophisticated electroanatomical mapping techniques may be required to identify its mechanism, location, and target area for a successful ablation...

Zahra Sharif Khodaei, M H Aliabadi
In this work, a multi-level decision fusion strategy is proposed which weighs the Value of Information (VoI) against the intended functions of a Structural Health Monitoring (SHM) system. This paper presents a multi-level approach for three different maintenance strategies in which the performance of the SHM systems is evaluated against its intended functions. Level 1 diagnosis results in damage existence with minimum sensors covering a large area by finding the maximum energy difference for the guided waves propagating in pristine structure and the post-impact state; Level 2 diagnosis provides damage detection and approximate localization using an approach based on Electro-Mechanical Impedance (EMI) measures, while Level 3 characterizes damage (exact location and size) in addition to its detection by utilising a Weighted Energy Arrival Method (WEAM)...

This chapter is intended as a primer to the most widely used neuroimaging methods available in the prediction, diagnosis and monitoring of the neurodegenerative diseases. We describe the imaging methods that allow us to examine brain structure, function and pathology and investigate neurodegenerative mechanisms in vivo. We describe methods to interrogate brain structure with magnetic resonance imaging (MRI), and brain function with molecular imaging, functional MRI and electro- and magneto-encephalography. We highlight the major neuroimaging advances, including brain stimulation and connectomics, which have brought new insights into a wide range of neurodegenerative diseases and describe some of the challenges in imaging clinical populations...

A novel label-free electrochemical strategy was established based on the unique electro-catalytic activity of graphene oxide (GO)-supported terminal deoxynucleotidyl transferase (TdT)-generated C-rich DNA nanotail-templated silver nanoclusters (DNA-AgNCs). TdT can catalyze the deoxycytidine triphosphate (dCTP) to the 3'-OH terminus of single-stranded DNA (ssDNA) with no template; then, in the presence of Ag(I), TdT-generated C-rich DNA sequence was employed for the synthetic template of AgNCs because of the formed complexes of nitrogen atoms of cytosine based with silver atoms...

INTRODUCTION: Human beings are accidental hosts for Cysticercus cellulosae showing varied clinical manifestations based on the site harbored by the parasitic cyst because of which disease profile remains unexplored at large. Besides this, diagnosis of the disease with a single conventional method is problematic due to lack of specificity and sensitivity. AIM: To assess the varied clinical manifestations and stratify based on imaging and serological methods for diagnosis of Neurocysticercosis (NCC) in our study population...

In the last twenty years, new imaging techniques to assess atrial function and to predict the risk of recurrence of atrial fibrillation after treatment have been developed. The present review deals with the role of these techniques in the detection of structural and functional changes of the atrium and diagnosis of atrial remodeling, particularly atrial fibrosis. Echocardiography allows the detection of anatomical, functional changes and deformation of the atrial wall during the phases of the cardiac cycle...
