Single-walled carbon nanotubes (SWCNTs) are thoroughly purified and dispersed in an aqueous solution of high molecular weight poly-L-lysine (pLlys). Human intestinal epithelial Caco-2/TC7 cells are incubated with the SWCNT dispersions in pLlys, and their effects on cell viability are studied by image flow cytometry. No significant changes are observed in the cell culture wells up to pLlys concentrations of 10 μg ml(-1). However, high mortality is detected at pLlys concentrations of 100 μg ml(-1). The presence of oxygen-free SWCNTs does not modify the effects of pLlys on cell cultures at any of the tested concentrations (≤1 μg ml(-1))...

REVIEW
Kyra Campbell, Jordi Casanova
During development, cells often switch between static and migratory behaviours. Such transitions are fundamental events in development and are linked to harmful consequences in pathology. It has long been considered that epithelial cells either migrate collectively as epithelial cells, or undergo an epithelial-to-mesenchymal transition and migrate as individual mesenchymal cells. Here, we assess what is currently known about in vivo cell migratory phenomena and hypothesise that such migratory behaviours do not fit into alternative and mutually exclusive categories...

Mutations of the IL12B and IL12RB1 genes underlie the development of IL-12 p40 and IL-12Rβ1 deficiencies, respectively, both of which cause predisposition to infection with weakly virulent mycobacteria and Salmonella. Infections with other intramacrophagic organisms have only been rarely observed. We identified two patients with visceral leishmaniasis who had autosomal recessive IL-12 p40 and IL-12Rβ1 deficiencies, respectively. This finding demonstrates the importance of IFN-γ immunity in the control of leishmaniasis...

Preclinical changes that precede the onset of symptoms and eventual diagnosis of Alzheimer's disease (AD) are a target for potential preventive interventions. A large body of evidence suggests that inflammation is closely associated with AD pathogenesis and may be a promising target pathway for such interventions. However, little is known about the association between systemic inflammation and preclinical AD pathophysiology. We first examined whether the acute-phase protein, alpha-2 macroglobulin (A2M), a major component of the innate immune system, was associated with cerebrospinal fluid (CSF) markers of neuronal injury in preclinical AD and risk of incident AD in the predictors of cognitive decline among normal individuals (BIOCARD) cohort...

BACKGROUND: Ischemia-reperfusion injury (IRI) is associated with morbidity and mortality. MicroRNAs (miRNAs) have emerged as regulators of IRI, and they are involved in the pathogenesis of organ rejection. Lidocaine has proven anti-inflammatory activity in several tissues but its modulation of miRNAs has not been investigated. This work aims to investigate the involvement of miRNAs in lung IRI in a lung auto-transplantation model and to investigate the effect of lidocaine. METHODS: Three groups (sham, control, and Lidocaine), each comprising 6 pigs, underwent a lung autotransplantation...

OBJECTIVE: Researchers in public health are often interested in examining the effect of several exposures on the incidence of a recurrent event. The aim of the present study is to assess how well the common-baseline hazard models perform to estimate the effect of multiple exposures on the hazard of presenting an episode of a recurrent event, in presence of event dependence and when the history of prior-episodes is unknown or is not taken into account. METHODS: Through a comprehensive simulation study, using specific-baseline hazard models as the reference, we evaluate the performance of common-baseline hazard models by means of several criteria: bias, mean squared error, coverage, confidence intervals mean length and compliance with the assumption of proportional hazards...

Several types of tumor are currently treated with antiangiogenic drugs. Unfortunately, most of these patients develop therapy resistance and succumb to the disease. Recently, a novel mechanism of resistance to antiangiogenics involving metabolic symbiosis of tumor cells has been described. Strategies to block resistance are emerging as a promising therapeutic approach.

Renal cell carcinoma (RCC) is a complex disease characterized by mutations in several genes. Loss of function of the von Hippel-Lindau (VHL) tumour suppressor gene is a very common finding in RCC and leads to up-regulation of hypoxia-inducible factor (HIF)-responsive genes accountable for angiogenesis and cell growth, such as platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF). Binding of these proteins to their cognate tyrosine kinase receptors on endothelial cells promotes angiogenesis...

Future development in spintronic devices will require an advanced control of spin currents, for example by an electric field. Here we demonstrate an approach that differs from previous proposals such as the Datta and Das modulator, and that is based on a van de Waals heterostructure of atomically thin graphene and semiconducting MoS2. Our device combines the superior spin transport properties of graphene with the strong spin-orbit coupling of MoS2 and allows switching of the spin current in the graphene channel between ON and OFF states by tuning the spin absorption into the MoS2 with a gate electrode...

2-Alkenylphenols react with allenes, upon treatment with catalytic amounts of Pd(II) and Cu(II), to give benzoxepine products in high yields and with very good regio- and diastereoselectivities. This contrasts with the results obtained with Rh catalysts, which provided chromene-like products through a pathway involving a β-hydrogen elimination step. Computational studies suggest that the square planar geometry of the palladium is critical to favor the reductive elimination process required for the formation of the oxepine products...

Given the low detection rates of CSF IgG-Oligoclonal bands (IgG-OCB) in non-European Multiple Sclerosis (MS) patients and higher specificity of the MRZH-reaction, we evaluated whether associating MRZH-reaction to CSF IgG-OCB detection improved investigation of suspected MS. Paired CSF and sera were analyzed for IgG-OCB and polyspecific viral antibodies. IgG-OCB were detected in 72% of MS patients and an MRZH-reaction in 67%. Combining IgG-OCB and MRZH raised detection of IgG abnormalities to 97% of studied MS patients...
