BACKGROUND: Distal involvement of autonomic nerve fibers is critical in familial amyloid polyneuropathy (FAP) due to transthyretin (TTR) mutation. This study compares different methods for assessing autonomic foot innervation in TTR-FAP patients. METHODS: Three groups of seven TTR-FAP patients were included, according to disease severity: clinically asymptomatic, moderate, or advanced neuropathy. Autonomic investigation included EMLA test and laser doppler flowmetry (LDF) for vasomotor aspects and Sudoscan® (measuring electrochemical skin conductance, ESC) and Neuropad® test for sudomotor aspects...

BACKGROUND/PURPOSE: Ankle sprains are common and potentially disabling musculoskeletal injuries that often lead to chronic ankle instability (CAI). CAI has been linked to impairments in postural and neuromuscular control; however, inconsistent findings have been reported. Individuals who experience a lateral ankle sprain, but do not develop instability, termed copers, may adapt different neuromuscular control strategies after injury. This study aimed to compare postural control and electromyographic (EMG) activity of hip and ankle muscles during the performance of the Star Excursion Balance Test (SEBT) in subjects with and without CAI...

INTRODUCTION: Totally minimally invasive esophagectomy (TMIE) is increasingly used in treatment of patients with esophageal carcinoma. However, it is currently unknown if McKeown TMIE or Ivor Lewis TMIE should be preferred for patients in whom both procedures are oncologically feasible. METHODS: The study was performed in 4 high-volume Dutch esophageal cancer centers between November 2009 and April 2017. Prospectively collected data from consecutive patients with esophageal cancer localized in the distal esophagus or gastroesophageal junction undergoing McKeown TMIE or Ivor Lewis TMIE were included...

Deep coalescence and introgression make it challenging to infer phylogenetic relationships among closely related species that arose through radiative speciation events. Despite numerous phylogenetic analyses and the availability of whole genomes, the phylogeny in the Anopheles gambiae species complex has not been confidently resolved. Here we extract over 80,000 coding and noncoding short segments from the genomes of six members of the species complex and use a Bayesian method under the multispecies coalescent model to infer the species tree, which takes into account genealogical heterogeneity across the genome and uncertainty in the gene trees...

Alternative splicing (AS) is a regulatory mechanism of gene expression that greatly expands the coding capacities of genomes by allowing the generation of multiple mRNAs from a single gene. In Drosophila, the mod(mdg4) locus is an extreme example of AS that produces more than 30 different mRNAs via trans-splicing that joins together the common exons and the 3' variable exons generated from alternative promoters. To map the regions required for trans-splicing, we have developed an assay for measuring trans-splicing events and identified a 73-bp region in the last common intron that is critical for trans-splicing of three pre-mRNAs synthesized from different DNA strands...

The relative biological effectiveness (RBE) of protons varies with multiple physical and biological factors. Phenomenological RBE models have been developed to include such factors in the estimation of a variable RBE, in contrast to the clinically applied constant RBE of 1.1. In this study, eleven published phenomenological RBE models and two plan-based models were explored and applied to simulated patient cases.
 Method and Materials: All models were analysed with respect to the distribution and range of linear energy transfer (LET) and reference radiation fractionation sensitivity ((α/β)<sub>x</sub>) of their respective experimental databases...

OBJECTIVES: To assess palatal vault height, tooth size, and dental arch dimensions in patients with unilateral and bilateral palatally displaced canines compared with a control group. MATERIALS AND METHODS: A sample of 66 patients (mean age: 11.5 ± 1.0 years) with 22 unilateral palatally displaced canines (UPDCs), 22 bilateral palatally displaced canines (BPDCs), and 22 controls (C) were consecutively recruited.

BACKGROUND: Madelung deformity is a congenital wrist condition characterized by volar subluxation of the wrist caused by premature growth arrest of the distal radius. Progressive symptoms can necessitate surgical intervention, yet optimal treatment strategy remains unknown. The aim of this study is to determine treatment options, surgical indications, and operative outcomes for Madelung deformity.

Aim Esophageal mucosal breaks are considered to occur circumferentially in locations with high exposure to acid. In the present study, we investigated the circumferential localization of esophageal mucosal breaks based on their distance from the esophagogastric junction. Subjects and methods The vertical and circumferential localization of 625 esophageal longitudinal mucosal breaks was examined in 398 patients with mild reflux esophagitis. Results The number of mucosal breaks in which the distal end was located 0-1 cm from the esophagogastric junction was 454, while those in which the distal end was located 1-2, 2-3, and >3 cm from the junction were 125, 28, and 18, respectively...

To facilitate the creation, modification, and optimization of patient-specific plates for distal femur fractures, a novel approach was proposed for the rapid and convenient design of patient-specific plates for patients' fractured femurs using feature parameterization. First, several femur parameter values were obtained for a specific patient and used to construct a restored surface model of the fractured femur. Next, combined with the particular femur anatomy and the fracture, a parameterized plate with a suitable shape was created automatically based on the parameter maps between the femur and plate...

Beclomethasone dipropionate (BDP) is a second-generation corticosteroid that use novel drug technologies to ensure colonic targeting and potentially reducing systemic corticosteroid concentrations. It is approved for treatment of patients with mild-to-moderate ulcerative colitis (UC) who do not respond to mesalazine. The gut-selective mechanism of action has the potential to improve the safety profile of beclomethasone dipropionate compared to other conventional corticosteroids. Areas covered: We reviewed the mechanism of action, efficacy and safety of beclomethasone dipropionate in the treatment of UC...

OBJECTIVE: Insulin resistance is associated with impaired receptor dependent hepatic uptake of triglyceride-rich lipoproteins (TRL), promoting hypertriglyceridemia and atherosclerosis. Next to low-density lipoprotein (LDL) receptor (LDLR) and syndecan-1, the LDLR-related protein 1 (LRP1) stimulated by insulin action contributes to the rapid clearance of TRL in the postprandial state. Here, we investigated the hypothesis that the adaptor protein phosphotyrosine interacting domain-containing protein 1 (PID1) regulates LRP1 function, thereby controlling hepatic endocytosis of postprandial lipoproteins...

BACKGROUND: The peripheral nervous system has greater regenerative potential than the CNS. This fact suggests the existence of molecules that act as key factors in nerve regeneration during molecular changes in the peripheral nervous system. METHODS: The right sciatic nerve of female Sprague-Dawley rats was exposed and transected at the mid-thigh level. Animals were sacrificed at 5, 10 or 35 days after nerve transection. Proximal and distal nerve segments (1-cm in length) were dissected...

Aim Self-application of properly performed compression bandages is generally considered as problematic. Therefore, the aim of this study was to measure the pressure of self-applied short stretch adjustable compression wrap compression systems (Juxta fit™) and to compare the results with the pressure achieved by bandaging other legs using the same material. Methods In the two training courses for nurses, specifically interested in leg ulcer treatment, the new bandage type of adjustable compression wrap was explained and workshops were organized, in which the interface pressure achieved by Juxta fit™ was measured...

Peripheral nerve injuries severely impair patients' quality of life since full recovery is seldom achieved. Upon axonal disruption, the distal nerve stump undergoes fragmentation, and myelin breaks down; the subsequent regeneration progression is dependent on cell debris removal. In addition to tissue clearance, macrophages release angiogenic and neurotrophic factors that contribute to axon growth. Based on the importance of macrophages for nerve regeneration, especially during the initial response to injury, we treated mice with granulocyte-macrophage colony-stimulating factor (GM-CSF) at various intervals after sciatic nerve crushing...
