Foot-and-mouth disease viruses from serotypes O, A and C have been crystallized. The particular strains studied include O1K, A1061, A22 Iraq 24/64, A24 Cruzeiro and C-S8c1. In addition, crystals have been grown of G67, a monoclonal antibody neutralization escape mutant derived from O1K, and of virus R100, recovered after the establishment of a persistent infection in baby hamster kidney cells with
A convolutional neural network for automatic myocardial segmentation of MR images is described and implemented, based on the readily available architecture SegNet. A general network trained on both end-systolic and end-diastolic images is determined to be superior to the networks trained on the separate data. The evaluation of myocardial segmentation is discussed, as well as the importance of manu
Fractional exhaled nitric oxide is elevated in allergen-provoked asthma. The cellular and molecular source of the elevated fractional exhaled nitric oxide is, however, uncertain.
There are limited data on human papillomavirus (HPV) type-specific cervical cancer risk among human immunodeficiency virus (HIV)-positive women. Previous studies have suggested that HPV 16 would be relatively less important as a causative agent among HIV-positive compared with HIV-negative women. This study investigates HPV type-specific cervical cancer risk in a population in which HIV is endemic
The NADPH oxidase 2 (NOX2) complex is a professional producer of reactive oxygen species (ROS) and is mainly expressed in phagocytes. While the activity of the NOX2 complex is essential for immunity against pathogens and protection against autoimmunity, its role in the development of malignant tumors remains unclear. We compared wild type and Ncf1 (m1J) mutated mice, which lack functional NOX2 com
Objectives To describe the clinical history and ultrasound findings in women with struma ovarii. Methods Women with a histological diagnosis of struma ovarii who bad undergone preoperative ultrasound examination were identified front the databases of five ultrasound centers. The tumors were characterized on the basis of ultrasound images,, ultrasound reports and research protocols (when applicable
The immobilization of functional biomolecules to surfaces is a critical process for the development of biosensors for disease diagnostics. In this work we report the patterned attachment of single chain fragment variable (scFv) antibodies to the surface of metal oxides by the photodeprotection of self-assembled monolayers, using near-UV light. The photodeprotection step alters the functionality at
Osteoblastoma is a bone forming tumor with histological features highly similar to osteoid osteoma; the discrimination between the tumor types is based on size and growth pattern. The vast majority of osteoblastomas are benign but there is a group of so-called aggressive osteoblastomas that can be diagnostically challenging at the histopathological level. The genetic aberrations required for osteo
OBJECTIVES: To develop and validate a recombinant vaccine to attenuate inflammation in arthritis by sustained neutralization of the anaphylatoxin C5a. METHODS: We constructed and expressed fusion protein of C5a and maltose binding protein. Efficacy of specific C5a neutralization was tested using the fusion protein as vaccine in three different arthritis mouse models: collagen induced arthritis (CI
Psoriasis is a complex genetic disease of unresolved pathogenesis with both heritable and environmental factors contributing to onset and severity. In addition to a disfiguring skin inflammation, approximately 10-40% of psoriasis patients suffer from destructive joint involvement. Previously, we reported that the CD18 hypomorphic PL/J mouse carrying a mutation resulting in reduced expression of th
The immune system is remarkable in many ways. It exerts immunity to defend us from foreign pathogens, while it is also responsible for maintaining tolerance to avoid autoimmune diseases and allergy. This thesis includes three separate papers concerning both tolerance and immunity. In paper I we report that repeated antigen stimulation results in an increased proportion of Foxp3+ cells in the CD4+
Human monocytes are a heterogeneous cell population classified into three different subsets: Classical CD14++CD16-, intermediate CD14++CD16+, and non-classical CD14+CD16++ monocytes. These subsets are distinguished by their differential expression of CD14 and CD16, and unique gene expression profile. So far, the variation in inter-cellular gene expression within the monocyte subsets is largely unk
The classical pathway complement regulator C4b-binding protein (C4BP) is composed of two polypeptides (alpha- and beta-chains), which form three plasma oligomers with different subunit compositions (alpha(7)beta(1), alpha(7)beta(0), and alpha(6)beta(1)). We show in this article that the C4BP alpha(7)beta(0) isoform (hereafter called C4BP[beta(-)] [C4BP lacking the beta-chain]), overexpressed under
Objective: To examine the contents of the Mayo-Portland Adaptability Inventory (MPAI-4) by mapping it to the International Classification of Functioning, Disability and Health (ICF). Methods: Each of the 30 scoreable items in the MPAI-4 was mapped to the most precise ICF categories. Results: All 30 items could be mapped to components and categories in the ICF. A total of 88 meaningful concepts wer
The objective of this study was to evaluate total antioxidant capacity (TAC), total phenolic content (TPH), and the identification of anthocyanidin and polyphenolic compounds in 13 colored potatoes collected from the Andean region of Bolivia, and understand how the chemical composition correlated with the botanical classification and molecular characterization of genes, ans (anthocyanidin synthase
Although Moraxella catarrhalis and Neisseria meningitidis are important human pathogens, they often colonize the human respiratory tract without causing overt clinical symptoms. Both pathogens express structurally unrelated proteins that share the ability to stimulate the adhesion molecule CEACAM1 expressed on human cells. Here we demonstrate that the interaction of CEACAM1 with ubiquitous surface
Objectives: The aim of this study was to evaluate the efficacy of the natural antioxidant astaxanthin in functional dyspepsia in different doses and compared with placebo. Design: The study was a controlled, prospective, randomized, and double blind trial. Participants: Patients with functional dyspepsia, divided into three groups with 44 individuals in each group (placebo, 16 mg, or 40 mg astaxan
Objective To describe the clinical history and ultrasound findings in women with ovarian Sertoli cell, Sertoli-Leydig cell and Leydig cell tumors. Methods Women with a histological diagnosis of Sertoli cell tumor, Sertoli-Leydig cell tumor or Leydig cell tumor who bad undergone preoperative ultrasound examination were identified from the databases of each of three participating ultrasound centers.
Older people often have companion animals, and the significance of animals in human lives should be considered by nurses-particularly in relation to older people's health, which can be affected by diseases. The incidence of stroke increases with age and disabilities as a result of stroke are common. This study aimed to explore older people's experiences of living with companion animals after strok
