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: The WHO recommends maternity waiting homes (MWH) as one intervention to improve maternal and newborn health. However, persistent structural, cultural and financial barriers in their design and implementation have resulted in mixed success in both their uptake and utilization. Guidance is needed on how to design a MWH intervention that is acceptable and sustainable. Using formative research and guided by a sustainability framework for health programs, we systematically collected data from key stakeholders and potential users in order to design a MWH intervention in Zambia that could overcome multi-dimensional barriers to accessing facility delivery, be acceptable to the community and be financially and operationally sustainable...

Perceptual errors are common contributors to missed diagnoses in the clinical practice of radiology. While the physical attributes of an image such as image resolution, signal-to-noise characteristics, and anatomic complexity are major causes of poor conspicuity of pathologic lesions, there are major interrelated cognitive contributors to visual errors. The first is satisfaction of search (SOS), where the detection of an abnormality results in premature termination of further search. Another form of incomplete search pattern is visual isolation, where a radiologist's search pattern is truncated to the main areas of an image, while little or no attention is given to peripheral areas...

Unlike their Western counterparts, some of the Eastern/Southern Mediterranean countries lack centralized coordinated blood transfusion services leading to an unequal blood safety level. This was recently highlighted by a recent World Health Organization (WHO) regional committee report in which WHO urges these countries to establish and implement a national blood system with well-coordinated blood transfusion activities and to make attempts to reach 100% voluntary non-remunerated blood donation. The objective is thus to meet the same levels or standards as Western countries in term of self-sufficiency and blood safety...

BACKGROUND: Lanosterol demethylase (CYP51), is an enzyme essential for fungal growth, and catalyzes an early step in the biosynthetic pathway of ergosterol, a sterol required for fungal cell membrane formation and integrity. CYP51 is the molecular target of the class of drugs referred to as 'azole antifungals.' VT-1161 is a novel, oral, selective inhibitor of fungal CYP51, and is being developed for the treatment of recurrent vulvovaginal candidiasis. OBJECTIVE: We evaluated the efficacy and safety of 4 dosing regimens of oral VT-1161 compared to placebo in women with recurrent vulvovaginal candidiasis, defined as at least 3 symptomatic episodes of acute vulvovaginal candidiasis within a 12-month period...

Emergency center visits are mostly unscheduled, undifferentiated, and unpredictable. A standardized triage process is an opportunity to obtain real-time data that paints a picture of the variation in acuity found in emergency centers. This is particularly pertinent as the influx of people seeking asylum or in transit mostly present with emergency care needs or first seek help at an emergency center. Triage not only reduces the risk of missing or losing a patient that may be deteriorating in the waiting room but also enables a time-critical response in the emergency care service provision...

STUDY QUESTION: Is ceramide-1-phosphate (C1P) an ovarian protective agent during alkylating chemotherapy? SUMMARY ANSWER: Local administration of C1P drastically reduces ovarian damage induced by cyclophosphamide (Cy) via protection of follicular reserve, restoration of hormone levels, inhibition of apoptosis and improvement of stromal vasculature, while protecting fertility, oocyte quality and uterine morphology. WHAT IS KNOWN ALREADY: Cancer-directed therapies cause accelerated loss of ovarian reserve and lead to premature ovarian failure (POF)...

ONC201 is a first-in-class, orally active anti-tumor agent that upregulates cytotoxic TRAIL pathway signaling in cancer cells. ONC201 has demonstrated safety and preliminary efficacy in the first-in-human trial where patients were dosed every 3 weeks. We hypothesized that dose-intensification of ONC201 may impact anti-tumor efficacy. We discovered that ONC201 exerts dose- and schedule-dependent effects on tumor progression and cell-death signaling in vivo. With dose intensification, we note a potent anti-metastasis effect and inhibition of cancer cell migration and invasion...

BACKGROUND: Revascularisation therapy is the curent gold standard of care for critical limb ischaemia (CLI), although a significant proportion of patients with CLI either are not fit for or do not respond well to this procedure. Recently, novel angiogeneic therapies such as the use of autologous cell-based therapy (CBT) have been examined, but the results of individual trials were inconsistent. OBJECTIVE: To pool all published studies that compared the safety and efficacy of autologous CBT derived from different sources and phenotypes with non cell-based therapy (NCT) in CLI patients...

Bisphenol A (BPA) is a chemical used in numerous industrial applications. Due to its well ascertained toxicity as endocrine disruptor, industries have started to replace it with other bisphenols whose alleged greater safety is scarcely supported by literature studies. In this study, the toxicity of seven BPA analogues was evaluated using both in silico and in vitro techniques, as compared to BPA toxicity. Furthermore, their affinity indexes for phospholipids (i.e. phospholipophilicity) were determined by immobilized artificial membrane liquid chromatography (IAM-LC) and possible relationships with in vitro toxic activity were also investigated...
