PURPOSE OF REVIEW: The approach to systemic sclerosis (SSc) has changed over the years with an increasing focus on the very early diagnosis of the disease. The terminology identifying patients in the early phase of SSc has been significantly confusing in the last three decades. The purpose of this article is to analyze how the concept of "very early SSc" has evolved over the years, which is the role of an early diagnosis and how early treat patients. RECENT FINDINGS: Several attempts have been made over time, to create more sensitive and specific classification criteria to include the largest number of SSc patients, also in the earliest phase...

OBJECTIVES: Properties of mesenchymal stromal/stem cells (MSCs) from systemic sclerosis (SSc) patients have been reported to be altered. MSC-based therapy may therefore rely on the use of allogeneic MSCs from healthy subjects. Here, we investigated whether heterologous MSCs could exhibit altered properties following exposure to oxidative environment of SSc sera. METHODS: Human bone marrow-derived MSCs were cultured in the presence of various sera: control human serum AB (SAB), SAB with HOCl-induced AOPPs at 400 or 1,000 µmol/L (SAB400 or SAB1000, respectively), or H2O2-induced AOPPs or SSc patient serum (PS)...

Patients with bilateral vestibular failure (BVF) suffer from postural and gait unsteadiness with an increased risk of falls. The aim of this study was to elucidate the differential role of otolith, semicircular canal (SSC), visual, proprioceptive, and cognitive influences on the postural stability of BVF patients. Center-of-pressure displacements were recorded by posturography under six conditions: target visibility; tonic head positions in the pitch plane; horizontal head shaking; sensory deprivation; dual task; and tandem stance...

In systemic sclerosis (SSc) immuno-inflammatory events are central to disease development. Amongst other mediators of inflammation, interleukin 17 (IL-17) and Th17 cells have been reported to be increased in the peripheral blood and target organs including involved skin in SSc. They participate and amplify inflammatory responses by inducing the production of cytokines such as IL-6, chemokines such as CCL2 and CXCL8 (IL-8), matrix metalloproteinases-1, -2, -9 and the expression of adhesion molecules in stromal cells including fibroblasts and endothelial cells...

BACKGROUND: Patients with severe sepsis frequently require intensive care unit (ICU) admission and different ICU care models may influence their outcomes. The mortality of severe septic patients between physician's high and low care volume remains unclear. METHODS: We analyzed the data from a three-year prospective observation study, which was performed in an adult medical ICU of Chung Gung Memorial Hospital, Keelung. The data included initial bundle therapies based on the Surviving Sepsis Campaign (SSC) guidelines for patients with severe sepsis...

BACKGROUND: The incidence of cancer is increased in patients with systemic sclerosis (SSc). Further, recent studies have also shown that the presence of anti-RNA polymerase III antibodies is associated with a higher incidence of cancer in this population. PATIENTS AND METHODS: Herein we present the cases of two men aged 56 and 23 years presenting SSc without anti-Scl70 or anti-centromere antibodies but with anti-RNA polymerase III antibodies. Clinical symptoms led us to prescribe more laboratory exams and both patients were diagnosed with cancer of the nasopharyngeal area...

We propose and demonstrate a silicon-based spot size converter (SSC), composed of two identical tapered channel waveguides and a Y-junction. The SSC is designed for first-order mode fiber-to-chip coupling on the basis of mode petal separation and the recombination method. Compared with a traditional on-chip SSC, this method is superior with reduced coupling loss when dealing with a higher-order mode. To the best of our knowledge, we present the first experimental observations of a higher-order SSC which is fully compatible with a standard fabrication process...

Spermatogenesis is a differentiation process during which diploid spermatogonial stem cells (SSCs) produce haploid spermatozoa. This highly specialized process is precisely controlled at the transcriptional, posttranscriptional, and translational levels. Here we report that N(6)-methyladenosine (m(6)A), an epitranscriptomic mark regulating gene expression, plays essential roles during spermatogenesis. We present comprehensive m(6)A mRNA methylomes of mouse spermatogenic cells from five developmental stages: undifferentiated spermatogonia, type A1 spermatogonia, preleptotene spermatocytes, pachytene/diplotene spermatocytes, and round spermatids...

Bisphenol A (BPA) is widely used as an industrial plasticizer, which is also an endocrine disruptor and considered to have adverse effects on reproduction. In male mammals, the long-term production of billions of spermatozoa relies on the regulated proliferation and differentiation of spermatogonial stem cells (SSCs). However, little is known about the effects of BPA on the viability of SSCs. To investigate the influence of BPA exposure on SSCs in vitro, we isolated SSCs from mouse and successfully established in vitro propagation of SSCs...

The characterization of circulating endothelial progenitor cells (EPCs) is fundamental to any study related to angiogenesis. Unfortunately, current literature lacks consistency in the definition of EPC subsets due to variations in isolation strategies and inconsistencies in the use of lineage markers. Here we address critical points in the identification of hematopoietic progenitor cells (HPCs), circulating endothelial cells (CECs), and culture-generated outgrowth endothelial cells (OECs) from blood samples of healthy adults (AB) and umbilical cord (UCB)...

We aimed at assessing the efficacy of autologous haematopoietic stem cell transplantation (HSCT) for skin sclerosis and lung function in systemic sclerosis (SSc). We performed a systematic literature review in the Pubmed and Scopus databases from the earliest records to March 2016. We assessed quality using the Cochrane tool for randomized studies, Newcastle-Ottawa scale for controlled-cohort studies and an 18-item quality appraisal checklist for case series. The primary outcome was the improvement of skin thickening using the modified Rodnan Skin Score (mRSS)...

BACKGROUND: Systemic sclerosis (SSc) fibroblasts show resistance apoptosis mechanisms, which enhances the fibrosis stage of the disease. Impaired function of p53 upregulated modulator of apoptosis (PUMA) has been related to deficits in p53-dependant apoptosis pathway. This study aimed to evaluate the transcriptional levels of p53 and PUMA mRNAs in fibroblasts from SSc patients and compare it with healthy individuals. METHODS: In this case-control study, skin biopsy samples were obtained from 19 patients with diffuse cutaneous SSc (DcSSc) and 16 healthy controls...

Systemic sclerosis (SSc) is a connective tissue disease that results in fibrosis in multiple organs. Various animal models for this disease have been developed, both genetic and induced. One of the induced models, sclerodermatous graft-versus-host disease (scl-GvHD), exhibits the main characteristics of SSc, but involves lethal γ-irradiation of recipients. We sought to develop a modified scl-GvHD model. Spleen cells from B10.D2 donor mice were transplanted into immunodeficient Rag-2 recipients on the BALB/c genetic background...

Hopping, skipping, jumping and sprinting are common tasks in both active play and competitive sports. These movements utilise the stretch-shortening cycle (SSC), which is considered a naturally occurring muscle action for most forms of human locomotion. This muscle action results in more efficient movements and helps optimise relative force generated per motor unit recruited. Innate SSC development throughout childhood and adolescence enables children to increase power (jump higher and sprint faster) as they mature...

Spermatogonial stem cells (SSCs) are the basis of spermatogenesis, which is dependent on the ability to self-renew and differentiation. Controlling self-renewal and differentiation of SSCs could apply to treatment of disease such as male infertility. Recently, in the field of stem cell research, it was demonstrated that effective increase in stem cell activity can be achieved by using growth factors derived from plant extracts. In this study, our aim is to investigate components from natural plant to improve the self-renewal of SSCs...
