Surface flatness assessment is necessary for quality control of metal sheets manufactured from steel coils by roll leveling and cutting. Mechanical-contact-based flatness sensors are being replaced by modern laser-based optical sensors that deliver accurate and dense reconstruction of metal sheet surfaces for flatness index computation. However, the surface range images captured by these optical sensors are corrupted by very specific kinds of noise due to vibrations caused by mechanical processes like degreasing, cleaning, polishing, shearing, and transporting roll systems.

This paper describes a method for calibrating multi camera and multi laser 3D triangulation systems, particularly for those using Scheimpflug adapters. Under this configuration, the focus plane of the camera is located at the laser plane, making it difficult to use traditional calibration methods, such as chessboard pattern-based strategies. Our method uses a conical calibration object whose intersections with the laser planes generate stepped line patterns that can be used to calculate the camera-laser homographies.

Flatness sensors are required for quality control of metal sheets obtained from steel coils by roller leveling and cutting systems. This article presents an innovative system for real-time robust surface estimation of flattened metal sheets composed of two line lasers and a conventional 2D camera. Laser plane triangulation is used for surface height retrieval along virtual surface fibers.

Introduction: Within-person trajectories of cerebrospinal fluid (CSF) biomarkers in Alzheimer's disease (AD) are not well defined.

Methods: We included 467 subjects from the BIOMARKAPD study with at least two serial CSF samples. Diagnoses were subjective cognitive decline (n = 75), mild cognitive impairment (n = 128), and AD dementia (n = 110), and a group of cognitively unimpaired subjects (n = 154) were also included.

Background: There is an increasing demand for physicians in Germany. At the same time, there are many licensed doctors who are not actively working as physicians. To win them back to their original field of expertise would be a policy to bring doctors into the health care system in a timely manner.

Introduction: Hip fractures are considered among one of the most disabling injuries in patients older than 60 years of age. This fractures are associated with a high incidence of mortality and it is the leading cause of hospital admission that requires surgical treatment in Orthopaedic Trauma Centers.

Methods: This systematic review aimed to group, classify and report the best level of evidence of physical therapy and rehabilitation of patients that have been treated with osteostynthesis after trochanteric or subtrochanteric fracture.

Purpose: Nosocomial infections account for one of the most serious complications in hospitalized patients around the world. Surgical site infections have significant economic implications, and surgical antisepsis plays an important role in such processes.

Methods: With prior approval by the Institutional Review Board and informed consent, 10 volunteers were randomly assigned to 3 protocols on hand antisepsis: protocol A (chloroxylenol 3%), protocol B (benzalkonium chloride at 1%), and protocol C (ethyl alcohol 61%, 1% chlorhexidine gluconate).

Exposure to intimate partner violence (IPV) and child maltreatment may have devastating consequences on children's development. The aim of this research was to examine the predictive associations between exposure to violence at home (witnessing violence against the mother and/or direct victimization by the parents) and adolescent internalizing and externalizing problems. A total of 613 Spanish adolescents (13-18 years) took part in this study.

Invasive lionfish ( and ) have spread widely across the western Atlantic and are recognized as a major threat to native marine biodiversity. Although lionfish inhabit both shallow reefs and mesophotic coral ecosystems (MCEs; reefs from 30 to 150 m depth), the primary management response implemented by many countries has been diver-led culling limited to reefs less than 30 m. However, many reef fish undergo ontogenetic migrations, with the largest and therefore most fecund individuals found at greatest depths.

Witnessing intimate partner violence (IPV) may have damaging effects on children's well-being and development. How children understand IPV affects the risk of their developing negative outcomes. Talking with children about the violent episodes they have experienced can change their beliefs regarding their parents' IPV, and therefore may also be a way to help them deal with these adverse experiences.

Background: Discovery and incorporation of biomarker panels to cancer studies enabled the understanding of genetic variation and its interference in carcinogenesis at molecular level. The potential association between single nucleotide polymorphism (SNP) 309 and increased development of tumors, such as hepatocellular carcinoma, has been subject to several studies. This is the first study on this association conducted in Brazil.

Purpose: The purpose of this study was to evaluate the clinical and sequential imaging follow-up results at a mean of 36 months after an arthroscopic technique for implantation of matrix-encapsulated autologous chondrocytes for the treatment of articular cartilage lesions on the femoral condyles.

Methods: Ten patients underwent arthroscopic implantation of autologous chondrocytes seeded onto a bioabsorbable scaffold. The patients were evaluated clinically using a visual analog scale (VAS) for pain and International Knee Documentation Committee (IKDC), Lysholm, and Tegner scores.

Background: Hallmarks of the pathogenesis of rotator cuff disease (RCD) include an abnormal immune response, angiogenesis, and altered variables of vascularity. Degenerative changes enhance production of pro-inflammatory, anti-inflammatory, and vascular angiogenesis-related cytokines (ARC) that play a pivotal role in the immune response to arthroscopic surgery and participate in the pathogenesis of RCD. The purpose of this study was to evaluate the ARC profile, ie, interleukin (IL): IL-1β, IL-6, IL-8, IL-10, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and angiogenin (ANG), in human peripheral blood serum and correlate this with early degenerative changes in patients with RCD.

Aim: The aim of this paper was to evaluate the hemodynamic behavior of carotid kinking, as assessed by color Doppler ultrasonography at baseline and during neck movements, and their relation to neurological symptoms.

Methods: In this cross-sectional study, 60 consecutive patients with non-atheromatous carotid kinking in whom diagnostic color Doppler ultrasonography investigation of neck vessels had been requested for clinical suspicion of atherosclerotic disease were evaluated. To evaluate if there were significant changes of blood velocities as a consequence of kinking, for each carotid artery we recorded systolic and diastolic velocities both in the segments proximal to kinking, as well as intra-kinking.

Background: Total hip arthroplasty is the most successful orthopedic procedure and the frequency of use of revision components has grown exponentially. The increased number of revisions results from the longer life expectancy of the population and the greater frequency of the hip arthroplasty indication among young patients. The purpose of this study is to evaluate the functional results of patients subjected to revision of the acetabular component using reinforcement rings.

Pigmented villonodular synovitis (PVNS) is a proliferative disorder of the synovial membrane of uncertain etiology. It commonly affects synovial joints of the appendicular skeleton and rarely affects the spine. We present the case of a young man presenting with a rapidly progressive myelopathy due to spinal cord compression by PVNS arising from a thoracic facet joint, which finally resulted in paraplegia.

Dolichoarteriopathies consist of tortuosity, kinking, or coiling of the extracranial carotid arteries. Some authors consider these alterations a consequence of atherosclerotic vessel remodeling, while others ascribe them to anatomical variations of embryological origin. The objective was to establish whether carotid dolichoarteriopathies belonged to a congenital origin or to acquired conditions.

Introduction: The effect of rheumatic and infectious diseases on skeletal remains provides an important source of information for knowledge of contemporary medicine. Few pathologic conditions have attracted so much interest as treponematoses. One of these, syphilis, was the most feared venereal disease throughout the civilized world until the introduction of penicillin in the 20th century.
