OBJECTIVES: The majority of scleroderma (SSc) patients present gastrointestinal involvement. Motility is usually compromised but few studies address permeability changes in the intestinal wall. ASCA (anti-Saccharomyces cerevisiae antibodies) positivity is associated with increased intestinal permeability. In this study we aimed to investigate ASCA positivity in SSc patients and its association with clinical, serological and epidemiological data. METHODS: Seventy-four SSc patients and 57 healthy controls were studied for ASCA (IgG and IgA) positivity by ELISA...

Running downhill, in comparison to running on the flat, appears to involve an exaggerated stretch-shortening cycle (SSC) due to greater impact loads and higher vertical velocity on landing, whilst also incurring a lower metabolic cost. Therefore, downhill running could facilitate higher volumes of training at higher speeds whilst performing an exaggerated SSC, potentially inducing favourable adaptations in running mechanics and running economy (RE). This investigation assessed the efficacy of a supplementary 8-week programme of downhill running as a means of enhancing RE in well-trained distance runners...

Systemic sclerosis (SSc) is a rare connective tissue disease characterized by three pathogenetic hallmarks: vasculopathy, dysregulation of the immune system, and fibrosis. A particular feature of SSc is the increased frequency of some types of malignancies, namely breast, lung, and hematological malignancies. Moreover, SSc may also be a paraneoplastic disease, again indicating a strong link between cancer and scleroderma. The reason of this association is still unknown; therefore, we aimed at investigating whether particular genetic or epigenetic factors may play a role in promoting cancer development in patients with SSc and whether some features are shared by the two conditions...

Systemic sclerosis (SSc) is a multisystem connective tissue disease characterized by vascular damage with non-specific inflammation and progressive fibrosis. The disease exhibits a large heterogeneity in both clinical and serological features. This diversity refers to the course of the disease, which is difficult to predict in many cases. Although poor prognostic factors are well known, it is not always possible to predict the course of the disease and the prognosis. Furthermore, the activity of disease is difficult to assess since both reversible and irreversible lesions can occur in one patient...

Despite continuous progress in medicine, sepsis remains the main cause of deaths in the intensive care unit. Liver failure complicating sepsis/septic shock has a significant impact on mortality in this group of patients. The pathophysiology of sepsis-associated liver dysfunction is very complicated and still not well understood. According to the Surviving Sepsis Campaign (SSC) Guidelines, the diagnosis of liver dysfunction during sepsis is based on the increase in bilirubin concentration >2 mg/dL and the occurrence of coagulation disorders with INR > 1...

Objective Statins, a class of 3-hydroxy-3 methyl-glutaryl-coenzyme A reductase inhibitors, are widely used for the treatment of atherosclerosis. Less is known about the role of statins in the treatment of vascular complication in systemic sclerosis (SSc). We therefore performed a short-term interventional study with simvastatin in patients with the diffuse variant of SSc and normal lipid profiles. Methods Twenty-five patients with diffuse SSc were enrolled and received simvastatin at a daily dose of 20 mg for 28 days...

Bottom-contact trawling generates large, moving clouds of suspended sediments that can alter the behaviour of organisms adjacent to trawl paths. While increased suspended sediment concentrations (SSCs) are known to cause glass sponges to arrest filtration in lab studies, the response of sponges to sediment in situ is not yet known. Here we describe arrest behaviours in response to increased SSCs recorded from the glass sponge Aphrocallistes vastus at the Fraser Ridge sponge reef in the Strait of Georgia, British Columbia, Canada...

Flesh reddening of 'Friar' plum (Prunus salicina Lindl.) fruit developed rapidly during storage at intermediate temperatures of 5 and 15 °C in comparison to flesh turning yellow at 25 °C and almost no colour change at 0 °C. Thus, modifications of phytochemicals and antioxidant activity during flesh reddening were investigated. Anthocyanins accumulated rapidly in reddening flesh tissue and cyanidin-3-O-glucoside was identified as the absolutely predominant individual anthocyanin. Anthocyanins contributed greatly to the antioxidant activity at 5 °C, and especially at 15 °C by combining with non-anthocyanin phenolics, including protocatechuic, syringic, trans-p-coumaric and caffeic acids...

Systemic sclerosis (SSc) is a connective tissue disease with high morbidity and mortality, characterized by autoimmunity, obliterative vasculopathy involving mainly the microvasculature, and fibrosis. SSc-specific nailfold capillaroscopic changes have been defined, and nailfold capillaroscopy (NFC) is now unequivocally accepted to be a cornerstone for the early diagnosis of SSc. However, the use of NFC in patients already diagnosed with SSc is still not standardized. Several studies have shown that NFC abnormalities correlate with disease activity and severity and are predictive for disease worsening, such as occurrence of new digital ulcers...

BACKGROUND: Transforming growth factor-β (TGF-β)/Smad signaling is well known to play a critical role in the pathogenesis of systemic sclerosis (SSc). We previously developed an artificial molecule, the histidine-pyridine-histidine ligand derivative HPH-15, which may have an antifibrotic effect. The purpose of the present study was to clarify the effects of this drug in human skin fibroblasts and in a preclinical model of SSc. METHODS: The effects of HPH-15 on expression of extracellular matrix components and TGF-β signaling in human dermal fibroblasts were analyzed...

BACKGROUND: Allicin and soluble solid content (SSC) in garlic is the responsible for its pungent flavor and odor. However, current conventional methods such as high-pressure liquid chromatography (HPLC), refractometer has a critical drawbacks in that they are time-consuming, labor-intensive and destructive procedures. The present study aimed to predict the allicin and soluble solid content (SSC) in garlic using hyperspectral imaging in combination with variable selection algorithms and calibration models...

OBJECTIVES: In systemic sclerosis (SSc), vascular injury leads to endothelial dysfunction with reduced capillary blood flow and tissue hypoxia. In SSc the angiogenesis is impaired and implicated in the microvascular damage. In severe vascular damage VEGF is reduced and endostatin is increased. Aim of this study was to evaluate the correlation between endostatin serum levels and microvascular and digital arteries damage. METHODS: Seventeen SSc patients were enrolled in this study...

The mechanisms underlying persistent fibroblast activation and myofibroblast phenoconversion in underlying multi-organ fibrosis in systemic sclerosis (SSc) remain incompletely understood, hindering effective therapies to slow or reverse the process. Cyclin-dependent kinase 5 (CDK5) is a pleiotropic member of the CDK family originally identified in neuronal cells. In contrast to other CDKs, CDK5 activity depends on its CDK5R1 subunit p35. Here we demonstrate that expression of p35 and CDK5 activity are induced by TGF-ß in fibroblasts and adipocytic cell types...

Litter size has a great impact on the profit of swine producers. Uterine development is an important determinant of reproduction efficiency and could hence affect litter size. Chinese Erhualian pig is one of the most prolific breeds in the world, even though large phenotypic variation in litter size was observed within Erhualian sows. To dissect the genetic basis of the phenotypic variation, we herein conducted genome-wide association studies for total number born and number born alive (NBA) of Erhualian sows...

PREMISE OF THE STUDY: As more plastomes are assembled, it is evident that rearrangements, losses, intergenic spacer expansion and contraction, and syntenic breaks within otherwise functioning plastids are more common than was thought previously, and such changes have developed independently in disparate lineages. However, to date, the magnoliids remain characterized by their highly conserved plastid genomes (plastomes). METHODS: Illumina HiSeq and MiSeq platforms were used to sequence the plastomes of Saruma henryi and those of representative species from each of the six taxonomic sections of Asarum...
