Daniel Glodeck, Jürgen Hesser, Lei Zheng
This paper focuses on a novel strategy increasing robustness with respect to local optima when using Mutual Information (MI) in multi-modal image registration. This is realized by integrating additional geometry information in the cost function. Hereby, the main innovation is a generalization of multi-metric registration approaches by means of a metric homotopy. Particularly we realize a method which automatically determines the parameters of the metric homotopy. To construct the cost function independent of the choice of the optimizer, the weighting is defined as a function of one of the metrics instead of optimizer steps...

Facial landmark detection is typically cast as a point-wise regression problem that focuses on how to build an effective image-to-point mapping function. In this paper, we propose an end-to-end deep learning approach for contextually discriminative feature construction together with effective facial structure modeling. The proposed learning approach is able to predict more contextually discriminative facial landmarks by capturing their associated contextual information. Moreover, we present a tree model to characterize human face structure and a structural loss function to measure the deformation cost between the ground-truth and predicted tree model, which are further incorporated into the proposed learning approach and jointly optimized within a unified framework...

Purpose of review: To encapsulate past and current research efforts focused on stem cell transplantation strategies to resolve radiation-induced cognitive dysfunction. Recent Findings: Transplantation of human stem cells in the irradiated brain was first shown to resolve radiation-induced cognitive dysfunction in a landmark paper by Acharya et al., appearing in PNAS in 2009. Since that time, work from the same laboratory as well as other groups have reported on the beneficial (as well as detrimental) effects of stem cell grafting after cranial radiation exposure...

Mechanical hyperalgesia defined as decreased pressure pain thresholds (PPTs) is commonly associated with pain. In this narrative review, we report the current state of the art within topographical pressure sensitivity maps. Such maps are based on multiple PPT assessments. The PPTs are assessed by an a priori defined grid with special focus on both spatial and temporal summation issues. The grid covers the muscle or the body region of interest using absolute or relative values determined from anatomical landmarks or anthropometric values...

When the U.S. Environmental Protection Agency (EPA) was established nearly 50 years ago, the nation faced serious threats to its air, land, and water, which in turn impacted human health. These threats were effectively addressed by the creation of EPA (in 1970) and many subsequent landmark environmental legislations which in turn significantly reduced threats to the Nation's environment and public health. A key element of historic legislation is research aimed at dealing with current and future problems. Today we face national and global challenges that go beyond classic media-specific (air, land, water) environmental legislation and require an integrated paradigm of action and engagement based on (1) innovation based on science and technology, (2) stakeholder engagement and collaboration, and (3) public education and support...

During the 2017 IFOS international congress in Paris, a roundtable discussion on the topic of functional and aesthetic rhinoplasty was organised. Five experts, from the five continents and renown in the field of rhinoplasty, were brought together to discuss the issue from an international perspective and to put forward a consensus or on the contrary practical differences. Five questions were put to the experts beforehand to guarantee independent answers, which were then discussed during the roundtable. The questions were the following: - What are the age limits for achieving a rhinoplasty? - Do you use objective measurements before, during and after surgery? (facial landmarks, airflow, peroperative measurements) - How do you manage the preoperative general information and computer imaging of the patient? - What are the indications in your practice to perform a CT-scan or endoscopic examination before doing a rhinoplasty? - What kind of graft or prosthesis do you use for an augmentation rhinoplasty? This paper offers a synthesis of the roundtable based on the experts' answers to the different questions...

Percutaneous coronary intervention (PCI) is 40 years old this year. From its humble beginnings of experimental work, PCI has transitioned over years with coronary artery stenting now a standard medical procedure performed throughout the world. Areas covered: The conversion from plain old balloon angioplasty (POBA) to the present era of drug eluting stents (DES) has been driven by many technological advances and large bodies of clinical trial evidence. The journey to present day practice has seen many setbacks, such as acute vessel closure with POBA; rates of instant restenosis with bare metal stents (BMS) and more recently, high rates of stent thrombosis with bioabsorbable platforms...

This paper aims to update the information available on the lithic assemblage from the entire sequence of TD6 now that the most recent excavations have been completed, and to explore possible changes in both occupational patterns and technological strategies evidenced in the unit. This is the first study to analyse the entire TD6 sequence, including subunits TD6.3 and TD6.1, which have never been studied, along with the better-known TD6.2 Homo antecessor-bearing subunit. We also present an analysis of several lithic refits found in TD6, as well as certain technical features that may help characterise the hominin occupations...

The Méthode de nomenclature chimique, published by the Académie Royale des Sciences in 1787, is rightly praised as a landmark in the history of early modern chemistry. It is also - though less rightly - considered to be a fruit of Lavoisier's Chemical Revolution. In fact, main features of the Méthode's nomenclatural and classificatory proposal rest on fundamental chemical conceptions that were shared by adherents of the phlogistic chemical system as well. After a short presentation of the Méthode's four authors (Berthollet, Fourcroy, Guyton de Morveau, and Lavoisier) and the circumstances of their collaboration, my paper will focus on those features of the Méthode that illuminate decisive achievements of the entire community of eighteenth-century chemists, as well as those features that reveal an unsettled state of many of its convictions...

Introduction Recent changes in surgical education have had an impact on our congenital training programmes. The mandate of the 8-hour workweek, a rapidly expanding knowledge base, and a host of other mandates has had an impact on the readiness of the fellows who are entering congenital programmes. To understand these issues completely, we interviewed the top congenital experts in the United States of America. The purpose of this paper is to share their insight and offer suggestions to address these challenges...

CHD affects millions of patients worldwide. Interventional therapies for CHD goes back to the mid-1960s when Bill Rashkind performed balloon atrial septostomy on a cyanotic baby with transposition of the great vessels. This was followed by development of balloon catheters to perform balloon valvuloplasties and angioplasties in the early to late 1980s. Although King and Mills performed the first transcatheter closure of secundum atrial septal defect in the mid-1970s, this procedure was better realised in the mid-1990s...

The use of laparoscopy in trauma surgery remains a debated topic, despite having been discussed in the literature for decades. The publication history of trauma laparoscopy was reviewed to identify trends, analyze study demographics, and summarize key papers, with hopes to better inform future areas of research. A systematic search of PubMed and Cochrane libraries was performed for English-language literature involving trauma laparoscopy through August 2017. Year published, number of subjects, study design, mechanism, type of laparoscopy (screening, therapeutic, diagnostic), journal, and location of study were recorded...

Regulatory guidances for nonclinical toxicity testing require brain evaluation but do not require a specific analytical strategy. The Society of Toxicologic Pathology (STP) has produced "best practice" recommendations for brain sampling and processing in general toxicity (GT) studies in adult rodents and nonrodents as well as developmental neurotoxicity (DNT) studies in rodents. This article explains acceptable brain trimming strategies as described in these 2 STP documents. Figures in the DNT and GT "best practices" illustrate coronal brain trimming at specific levels as defined by discrete external and internal anatomic landmarks...

INTRODUCTION: Many biological structures show recurring tiling patterns on one structural level or the other. Current image acquisition techniques are able to resolve those tiling patterns to allow quantitative analyses. The resulting image data, however, may contain an enormous number of elements. This renders manual image analysis infeasible, in particular when statistical analysis is to be conducted, requiring a larger number of image data to be analyzed. As a consequence, the analysis process needs to be automated to a large degree...

PURPOSE OF REVIEW: The head and neck cancer (HNC) survivorship experience is unique among cancer populations. This review seeks to explore the HNC survivor experience associated with altered upper aerodigestive tract (UADT) function using principles of survivorship. RECENT FINDINGS: HNC survivors experience complex physical, functional, and psychosocial challenges related to UADT dysfunction. Interventions need to address all of these dimensions being mindful of the survivor experience...

This paper introduces statistical shape modelling (SSM) for use in osteoarchaeology research. SSM is a full field, multi-material analytical technique, and is presented as a supplementary geometric morphometric (GM) tool. Lower mandibular canines from two archaeological populations and one modern population were sampled, digitised using micro-CT, aligned, registered to a baseline and statistically modelled using principal component analysis (PCA). Sample material properties were incorporated as a binary enamel/dentin parameter...

Endoscopy imaging of the gastrointestinal (GI) tract has evolved tremendously over the last few decades. Key milestones in the development of endoscopy imaging include the use of various dyes for chromoendoscopy, the application of optical magnification in endoscopy, the introduction of high-definition image capturing and display technology and the application of altered illuminating light to achieve vascular and surface enhancement. Aims of this review paper are to summarize the development and evolution of modern endoscopy imaging and in particular, imaged-enhanced endoscopy (IEE), to promote appropriate usage, and to guide future development of good endoscopy practice...
