Strongyluris oscari Travassos, 1923, parasite of Topidurus torquatus (Wied-Neuwied, 1820) (Tropiduridae) from Brazil and Pharyngodon mamillatus (Linstow, 1897) of Chalcides ocellatus (Forskal, 1775) (Scincidae) from Egypt, were redescribed based on light and scanning electron microscopy, and re-evaluation of specimens from parasitological collections. The following features were accurately observed in S. oscari for the first time: structure of lips and pharyngeal valve, presence and distribution of somatic papillae, number and arrangement of caudal papillae, presence of inner sclerotised structures supporting the ventral sucker and the ventral region in tail of males, and structure of the posterior anal lip in females...

INTRODUCTION: The aim of this study was to determine the morphologic characteristics of mandibular first molars having 2 canals in distal roots. Interorifice distance, buccal bone thickness, and root curvature were evaluated using cone-beam computed tomography images in a Korean population. METHODS: In total, 1958 mandibular first molars were evaluated in axial, coronal, sagittal, and paraxial planes. Distal roots having 2 canals were classified according to their root and canal shapes (2 roots, 2 canals [2R2C]; 1 root, 2 canals with 2 apical foramina [1R2C(2-2)]; and 1 root, 2 canals with 1 apical foramen [1R2C(2-1)])...

In this study, to advance smart health applications which have increasing security/privacy requirements, we propose a novel highly wearable ECG-based user identification system, empowered by both non-standard convenient ECG lead configurations and deep learning techniques. Specifically, to achieve a super wearability, we suggest situating all the ECG electrodes on the left upper-arm, or behind the ears, and successfully obtain weak but distinguishable ECG waveforms. Afterwards, to identify individuals from weak ECG, we further present a two-stage framework, including ECG imaging and deep feature learning/identification...

In this case study, we describe our experiences with a woman employed as a housemaid who sought unsafe abortion services from a private doctor. This was her sixth pregnancy, after previously giving birth to one son and two daughters and undergoing two induced abortions. Her husband remained opposed to the use of contraception. Initially, she had sought medical termination of pregnancy through a government hospital but was denied because of procedural delays, specifically the non-availability of an ultrasonography report consequent to a lack of proof of identity (ie, the AADHAAR card, a unique identification card for recording biometric and demographic data in India)...

The work describes features of the compressed sensing (CS) approach utilized for development of a wearable system for wrist vein recognition with single-pixel detection; we consider this system useful for biometrics authentication purposes. The CS approach implies use of a spatial light modulation (SLM) which, in our case, can be performed differently - with a liquid crystal display or diffusely scattering medium. We show that compressed sensing combined with above mentioned means of spatial light modulation allows us to avoid using an optical system - a limiting factor for wearable devices...

We propose an optical cryptosystem for encrypting images of multi-depth objects based on the combination of optical heterodyne technique and fingerprint keys. Optical heterodyning requires two optical beams to be mixed. For encryption, each optical beam is modulated by an optical mask containing either the fingerprint of the person who is sending, or receiving the image. The pair of optical masks are taken as the encryption keys. Subsequently, the two beams are used to scan over a multi-depth 3-D object to obtain an encrypted hologram...

The purpose of this study is to evaluate the effect of three-dimensional preformed titanium membrane (3D-PFTM) to enhance mechanical properties and ability of bone regeneration on the peri-implant bone defect. 3D-PFTMs by new mechanically compressive molding technology and manually shaped- (MS-) PFTMs by hand manipulation were applied in artificial peri-implant bone defect model for static compressive load test and cyclic fatigue load test. In 12 implants installed in the mandibular of three beagle dogs, six 3D-PFTMs, and six collagen membranes (CM) randomly were applied to 2...

PURPOSE: Our objective is to evaluate the "reach" component of the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework by comparing prediabetics who were and were not interested in enrolling in a free work site diabetes prevention program (DPP) during the first year of the program. Reach is defined as the proportion of eligible participants who enroll in a health program. DESIGN: A cross-sectional study design was used. SETTING: The setting was a large health system in the Midwest...

Prenatal alcohol exposure often results in an array of fetal developmental abnormalities termed fetal alcohol spectrum disorders (FASDs). Despite the high prevalence of FASDs, the pathophysiology of fetal damage by alcohol remains poorly understood. One of the major obstacles in studying fetal development in response to alcohol exposure is the inability to standardize the amount, pattern of alcohol consumption, and peak blood alcohol levels in pregnant mothers. In the present study, we used Doppler ultrasonography to assess fetal growth and cardiovascular parameters in response to alcohol exposure in pregnant baboons...

OBJECTIVE: Describe the ocular biometric parameters and their associations in a population of cataract surgery candidates. METHODS: A cross-sectional study of 13,012 eyes of 6,506 patients was performed. Biometric parameters of the eyes were measured by optical low-coherence reflectometry. The axial length (AL), mean keratometry (K) and astigmatism, anterior chamber depth (ACD) (epithelium to lens), lens thickness (LT), and Corneal Diameter (CD) were evaluated. RESULTS: The mean age was 69 ± 10 years (44-99 years)...

BACKGROUND: The aim of this study was to determine the prevalence of refractive errors and their association with glycaemic control among adults with type 2 diabetes mellitus (T2DM) in eastern China. METHODS: A community-based survey, including 913 adults with T2DM aged 30 to 89 years, was conducted. Refractive error was assessed by autorefraction, after which subjective refraction was performed. Ocular biometric parameters were measured by non-contact partial coherence laser interferometry...

Finger-vein recognition, a new and advanced biometrics recognition method, is attracting the attention of researchers because of its advantages such as high recognition performance and lesser likelihood of theft and inaccuracies occurring on account of skin condition defects. However, as reported by previous researchers, it is possible to attack a finger-vein recognition system by using presentation attack (fake) finger-vein images. As a result, spoof detection, named as presentation attack detection (PAD), is necessary in such recognition systems...

The use of the physical appearance of the deceased has become more important because the available antemortem information for comparisons may consist only of a physical description and photographs. Twenty-one articles dealing with the identification based on the physiognomic features of the human body were selected for review and were divided into four sections: (i) visual recognition, (ii) specific facial/body areas, (iii) biometrics, and (iv) dental superimposition. While opinions about the reliability of the visual recognition differ, the search showed that it has been used in mass disasters, even without testing its objectivity and reliability...

Selection indices commonly utilize economic weights, which become arbitrary genetic gains. In popcorn, this is even more evident due to the negative correlation between the main characteristics of economic importance - grain yield and popping expansion. As an option in the use of classical biometrics as a selection index, the optimal procedure restricted maximum likelihood/best linear unbiased predictor (REML/BLUP) allows the simultaneous estimation of genetic parameters and the prediction of genotypic values...

INTRODUCTION: Psoriasis is a chronic systemic inflammatory disease where the skin and the joints are the primary targets. Despite the fact that psoriasis carries minimal risk of mortality, it is associated with significant morbidity which may have a significant impact on quality of life of patients. Globally, psoriasis has been reported to be associated with Metabolic Syndrome (MS) including obesity, dyslipidemia, diabetes and hypertension. Association of MS and its various components with psoriasis has been consistently reported in various studies, but there is a paucity of data on this association from the Indian subcontinent...
