Host recognition and immune-mediated foreign body response to biomaterials can compromise the performance of implanted medical devices. To identify key cell and cytokine targets, here we perform in-depth systems analysis of innate and adaptive immune system responses to implanted biomaterials in rodents and non-human primates. While macrophages are indispensable to the fibrotic cascade, surprisingly neutrophils and complement are not. Macrophages, via CXCL13, lead to downstream B cell recruitment, which further potentiated fibrosis, as confirmed by B cell knockout and CXCL13 neutralization...

BACKGROUND AND OBJECTIVE: The real-world tolerability of pirfenidone and nintedanib in non-clinical trial patients is unknown. Many patients with pulmonary fibrosis have significant medical co-morbidities or baseline characteristics that exclude them from clinical trial participation. METHODS: We conducted a retrospective chart review study on subjects prescribed nintedanib or pirfenidone for pulmonary fibrosis treatment (any aetiology) from September 2014 to February 2016...

Chordoid gliomas are slowly growing third ventricular tumors that can be challenging to manage clinically. Rapid progression causing death has not been previously reported for this tumor type. We present and discuss a case of chordoid glioma that arose in a 46-year-old female who presented with progressive fatigue, headache, and altered mental status, attributable to severe hydrocephalus caused by a third ventricular mass. She underwent urgent subtotal resection and ventriculo-peritoneal shunt placements. Post-operative MRI noted residual tumor in the anterior resection cavity...

BACKGROUND: Experimental work on skin hydration is technologically challenging, and mostly limited to observations where environmental conditions are constant. In some cases, like diapered baby skin, such work is practically unfeasible, yet it is important to understand potential effects of diapering on skin condition. To overcome this challenge, in part, we developed a computer simulation model of reversible transient skin hydration effects. METHODS: Skin hydration model by Li et al...

Neural crest cells (NCCs) are a multipotent, migratory cell population that generates an astonishingly diverse array of cell types during vertebrate development. The trunk neural crest has long been considered of particular significance. First, it has been held that the trunk neural crest has a morphogenetic role, acting to coordinate the development of the peripheral nervous system, secretory cells of the endocrine system and pigment cells of the skin. Second, the trunk neural crest additionally has skeletal potential...

The dramatic metamorphosis from larva to adult of insect orders such as Diptera cannot usually be witnessed because it occurs within an opaque structure. For the cyclorrhaphous dipterans, such as blow flies, this structure is the puparium, formed from the larval cuticle. Here, we reveal metamorphosis within the puparium of a blow fly at higher temporal resolution than previously possible with two-dimensional time-lapse videos created using the X-ray within a micro-computed tomography scanner, imaging development at 1 min and 2 min intervals...

Melanomas accumulate a high burden of mutations that could potentially generate neoantigens, yet somehow suppress the immune response to facilitate continued growth. In this study, we identify a subset of human melanomas that have loss-of-function mutations in ATR, a kinase that recognizes and repairs UV-induced DNA damage and is required for cellular proliferation. ATR mutant tumors exhibit both the accumulation of multiple mutations and the altered expression of inflammatory genes, resulting in decreased T cell recruitment and increased recruitment of macrophages known to spur tumor invasion...

The genus Prochyliza Walker is recorded for the first time from the Afrotropical Region. A new species, Prochyliza ignifera sp. nov., is described from the Indian Ocean islands of Aldabra and La Réunion. The status of this species as possibly the most primitive in the genus Prochyliza is hypothesised and discussed, raising some questions about the taxonomy and the zoogeographical origin of the group. The holotype of Piophila viridicollis Macquart from La Réunion was studied and it is instated as a subjective junior synonym of Piophila casei (Linnaeus), syn...

OBJECTIVES: Currently, the French High Authority for Health does not recommend mass screening for prostate cancer (PCa), due to the risk of over-treatment, notably of low risk patients. Our study is intended to reflect the therapeutic attitudes for the management of patients classified as low risk of progression in French clinical centers. METHODS: For all positive prostate biopsies performed during 2012 and 2013 in five French departments of urology, clinicopathological characteristics required to calculate the d'Amico risk group and the Cancer of the Prostate Risk Assessment (CAPRA) score were filled...

Molecular dynamics (MD) simulations were conducted to study nucleation of water at 350 K in argon using TIP4P and TIP4P/2005 water models. We found that the stability of any cluster, even if large, strongly depends on the energetic interactions with its vicinity, while the stable clusters change their composition almost entirely during nucleation. Using the threshold method, direct nucleation rates are obtained. Our nucleation rates are found to be 1.08×10(27) cm(-3) s(-1) for TIP4P and 2.30×10(27) cm(-3) s(-1) for TIP4P/2005...

INTRODUCTION: Glucagon-like peptide-1 (GLP-1) receptor agonists are used successfully in the treatment of patients with type 2 diabetes as they are associated with low hypoglycemia rates, weight loss and improved glycemic control. This study compared, in the Spanish setting, the cost-effectiveness of liraglutide 1.8 mg versus lixisenatide 20 μg, both GLP-1 receptor agonists, for patients with type 2 diabetes who had not achieved glycemic control targets on metformin monotherapy. METHODS: The IMS CORE Diabetes Model was used to project clinical outcomes and costs, expressed in 2015 Euros, over patient lifetimes...

Endothelial progenitor cells (EPCs) constitute a promising alternative in cardiovascular regenerative medicine due to their assigned role in angiogenesis and vascular repair. In response to injury, EPCs promote vascular remodeling by replacement of damaged endothelial cells and/or by secreting angiogenic factors over the damaged tissue. Nevertheless, such mechanisms need to be further characterized. In the current approach we have evaluated the initial response of early EPCs (eEPCs) from healthy individuals after direct contact with the factors released by carotid arteries complicated with atherosclerotic plaques (AP), in order to understand the mechanisms underlying the neovascularization and remodeling properties assigned to these cells...
