Our understanding of how cells communicate has undergone a paradigm shift since the recent recognition of the role of exosomes in intercellular signaling. In this study, we investigated whether oxygen tension alters the exosome release and miRNA profile from extravillous trophoblast (EVT) cells, modifying their bioactivity on endothelial cells (EC). Furthermore, we have established the exosomal miRNA profile at early gestation in women who develop pre-eclampsia (PE) and spontaneous preterm birth (SPTB). HTR-8/SVneo cells were used as an EVT model...

BACKGROUND: Physical inactivity contributes to many health issues. The WHO-recommended physical activity for adolescents encompasses aerobic, resistance, and bone strengthening exercises aimed at achieving health-related physical fitness. Heart rate variability (HRV) and maximal aerobic capacity (VO2max) are considered as noninvasive measures of cardiovascular health. The objective of this study is to compare the effect of structured and unstructured physical training on maximal aerobic capacity and HRV among adolescents...

Ocular inflammatory diseases can present as isolated conditions but also as part of systemic inflammatory diseases. Anterior uveitis is closely related to SpA and shares the common genetic background of HLA-B27. Other ocular manifestations, such as episcleritis and scleritis, may also occur, although less frequently. Therefore, ocular involvement has been included as one of the important clinical features of SpA in the recently published classification criteria for axial and peripheral disease. However, there are a wide variety of aetiologies for ocular diseases and this must be considered in assessment of SpA...

Sclerosing polycystic adenosis (SPA) is a rare benign neoplasm of the salivary gland which resembles the fibrocystic disease of the breast clinically as well as morphologically. This entity has varied morphological presentation on fine needle aspiration. Only a few case reports and occasional case series are found in the literature describing its cytology. Here we are presenting a case of SPA in the parotid gland in a 13-year-old male patient who presented with a slow growing infra-auricular mass since one year without any other symptoms...

Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) is increasingly related to human infections. Farmers and veterinarians have the highest risk, but infections have also occurred in individuals without prior contact to livestock. Clonal complex (CC) 398 is the predominant LA-MRSA lineage causing human infections, and although pigs are the major source of CC398 worldwide, poultry and other animals are also reservoirs. This raises concern for transmission of MRSA via meat. In this study, the occurrence and characteristics of S...

Ankylosing Spondylitis (AS) is the prototype of a group of systemic rheumatic diseases collectively referred to as Spondyloarthitides (SpA). It is has recently become clear that AS is not as rare as previously thought and, although it has an early onset in life affecting patients in their reproductive years, it has not been proved to adversely affect fertility in females. Furthermore, new pharmaceutical agents have been introduced for its therapeutical management. The interaction between systematic rheumatic diseases and pregnancy has been under investigation with the majority of studies focusing on systemic lupus erythematosus and rheumatoid arthritis (RA)...

BACKGROUND: Atopic dermatitis (AD) is a prevalent disease with significant impact on physical health and quality of life. Staphylococcus aureus (S. aureus) has been directly correlated to disease severity, and may also be a contributing causal factor in the pathogenesis of AD. The primary aim of the present study was to assess differences in S. aureus colonization in AD patients with and without filaggrin gene (FLG) mutations. Secondarily, to assess disease severity in relation to S. aureus colonization...

The E3 ligase CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) has been known to mediate key signaling factors for degradation via the ubiquitin/26S proteasome pathway in both plants and animals. Here, we report a noncanonical function of Arabidopsis COP1, the central repressor of photomorphogenesis, in the form of a COP1/ SUPPRESSOR of phyA-105 (SPA) complex. We show that the COP1/SPA complex associates with and stabilizes PHYTOCHROME INTERACTING FACTOR 3 (PIF3) to repress photomorphogenesis in the dark. We identify the GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2) as a kinase of PIF3, which induces PIF3 degradation via 26S proteasome during skotomorphogenesis...

Soft pneumatic actuators (SPAs) are found in mobile robots, assistive wearable devices, and rehabilitative technologies. While soft actuators have been one of the most crucial elements of technology leading the development of the soft robotics field, they fall short of force output and bandwidth requirements for many tasks. In addition, other general problems remain open, including robustness, controllability, and repeatability. The SPA-pack architecture presented here aims to satisfy these standards of reliability crucial to the field of soft robotics, while also improving the basic performance capabilities of SPAs by borrowing advantages leveraged ubiquitously in biology; namely, the structured parallel arrangement of lower power actuators to form the basis of a larger and more powerful actuator module...

Background. Clinical, laboratory, and radiologic parameters are used for diagnosis and classification of spondyloarthritis (SpA). Magnetic resonance imaging (MRI) of sacroiliac (SI) joints is being increasingly used to detect early sacroiliitis. We decided to evaluate the interobserver agreement in MRI findings of SI joints of SpA patients between a local radiologist, a rheumatologist, and an expert radiologist in musculoskeletal diseases. Methods. 66 MRI images of the SI joints of patients with established diagnosis of SpA were evaluated...

Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) have been reported in various countries worldwide. However, although China is one of the biggest pig and pork producers, large-scale studies on pig-associated LA-MRSA from China are scarce. The aims of this study were to analyze 2420 non-duplicate samples collected from pigs at swine farms and slaughterhouses in different regions in China during 2014 for the prevalence of pig-associated MRSA and to determine the antimicrobial resistance pheno- and genotypes of the respective isolates...

OBJECTIVE: Radiographs of sacroiliac (SI) joints are used for the detection of structural damage in patients with axial spondyloarthritis (axSpA), but are often difficult to interpret. Here, we address the question how the T1-weighted MRI (T1w MRI) sequence compares with radiography for SI joints' structural lesions using low-dose CT as the standard of reference. METHODS: Radiographs, T1w MRI and low-dose CT of the SI joints from 110 patients (mean age 36.1 (19-57) years, 52% males and 48% females; 53% with axSpA, 21 non-radiographic axSpA and 32% radiographic axSpA, 47% with non-SpA) referred to the rheumatologist because of unclear chronic back pain, but possible axSpA, were scored for structural lesions (erosions, sclerosis, joint space changes and an overall impression of positivity)...
