XB 1254-690 is a dipping low mass X-ray binary system hosting a neutron star and showing type I X-ray bursts. We aim at obtaining a more accurate orbital ephemeris and at constraining the orbital period derivative of the system for the first time. In addition, we want to better constrain the distance to the source in order to locate the system in a well defined evolutive scenario. We apply, for the first time, an orbital timing technique to XB 1254-690, using the arrival times of the dips present in the light curves that have been collected during 26 yr of X-ray pointed observations acquired from different space missions. We estimate the dip arrival times using a statistical method that weights the count-rate inside the dip with respect to the level of persistent emission outside the dip. We fit the obtained delays as a function of the orbital cycles both with a linear and a quadratic function. We infer the orbital ephemeris of XB 1254-690, improving the accuracy of the orbital period with respect to previous estimates. We infer a mass of M2 = 0.42 ± 0.04 M for the donor star, in agreement with estimations already present in literature, assuming that the star is in thermal equilibrium while it transfers part of its mass via the inner Lagrangian point, and assuming a neutron star mass of 1.4 Mo. Using these assumptions, we also constrain the distance to the source, finding a value of 7.6±0.8 kpc. Finally, we discuss the evolution of the system, suggesting that it is compatible with a conservative mass transfer driven by magnetic braking.

In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry(eXTP) mission for determining the nature of dense matter; neutron star cores host an extreme density regime which cannot be replicated in a terrestrial laboratory. The tightest statistical constraints on the dense matter equation of state will come from pulse profile modelling of accretion-powered pulsars, burst oscillation sources, and rotation-powered pulsars. Additional constraints will derive from spin measurements, burst spectra, and properties of the accretion flows in the vicinity of the neutron star. Under development by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Sciences, the eXTP mission is expected to be launched in the mid 2020 s.

In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to accretion flows in the strong field gravity regime around both stellar-mass and supermassive black-holes. eXTP has the unique capability of using advanced "spectral-timing-polarimetry" techniques to analyze the rapid variations with three orthogonal diagnostics of the flow and its geometry, yielding unprecedented insight into the inner accreting regions, the effects of strong field gravity on the material within them and the powerful outflows which are driven by the accretion process.

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s.

Chronic wounds are defined as wounds that fail to proceed through the normal phases of wound healing in an orderly and timely manner.The most common and inevitable impairment to wound healing is the installation of an infection,usually in the case of chronic wounds.Therefore,the objective of the present review was to identify the importance of copper nanoparticles in dressings for wound healing.Nanoparticles such as silver,gold and copper combat infectious processes through the inhibition of protein synthesis,peroxidation of the cell membrane and destroying the nucleic acids of bacteria and viruses.Among bioactive nanoparticles,copper plays a complex role in various cells,it modulates several cytokines and growth factor mechanisms of action and is essentially involved in all stages of the wound healing process.More importantly,copper plays a key role in skin regeneration and angiogenesis and accelerates the healing process through induction of vascular endothelial growth factor(VEGF)and angiogenesis by hypoxia-induced factor-1-alpha(HIF-1α)action where copper enhances HIF-1αexpression and HIF-1αbinding to the critical motifs in the promoter and putative enhancer regions of HIF-1-regulated genes.

Magnetic resonance imaging markers for early diagnosis of Parkinson's disease

Parkinson＇s disease （PD） is a neurodegenerative disorder characterized by selective and progressive degeneration, as well as loss of dopaminergic neurons in the substantia nigra. In PD, approximately 60-70% of nigrostriatal neurons are degenerated and 80% of content of the striatal dopamine is reduced before the diagnosis can be established according to widely accepted clinical diagnostic criteria. This condition describes a stage of disease called ＂prodromal＂, where non-motor symptoms, such as olfactory dysfunction, constipation, rapid eye movement behaviour disorder, depression, precede motor sign of PD. Detection of prodromal phase of PD is becoming an important goal for determining the prognosis and choosing a suitable treatment strategy. In this review, we present some non-invasive instrumental approaches that could be useful to identify patients in the prodromal phase of PD or in an early clinical phase, when the first motor symptoms begin to be apparent. Conventional magnetic resonance imaging （MRI） and advanced MRI techniques, such as magnetic resonance spectroscopy imaging, diffusion-weighted and diffusion tensor imaging and functional MRI, are useful to differentiate early PD with initial motor symptoms from atypical parkinsonian disorders, thus, making easier early diagnosis. Functional MRI and diffusion tensor imaging techniques can show abnormalities in the olfactory system in prodromal PD.

Background:Still little is known about the impact on right ventricle function of the 2 main approaches to Norwood palliation in Hypoplastic left heart syndrome,the right ventricle-pulmonary artery shunt(RVPAS)and the modified Blalock-Taussig shunt(mBTS).Methods:The cohort included 27 patients with Hypoplastic left heart syndrome(10 in the mBTS group,17 in the RVPAS group).Longitudinal strain,tricuspid annulus peak systolic excursion and fractional area change were evaluated before Norwood and in four different breakpoints in the steady-state after Norwood procedure(30-days,90-days,140-days and 200-days after Norwood).Results:No significant differences were found in all standard echocardiographic functional parameters between the two groups at any times.However,when we compared right ventricle function before and after Norwood procedure,longitudinal strain significantly improved in mBTS group compared to pre-surgical assessment(after 90-days:mBTS+27,35%±43,47 vs.RVPAS-8,20%±25,25,p=0,03;after 200-days:mBTS+10.19%±36.58 vs.RVPAS-21.64%±30.43,p=0.04).Conclusion:The mBTS group,which did not receive any ventriculotomy,showed a significant increase in right ventricle longitudinal strain during convalescence.These data support the use of longitudinal strain in Hypoplastic left heart syndrome evaluation and may suggest potential value in terms of cardiac mechanics in using mBTS,preserving the right ventricle integrity.

Anxiety and depression in Parkinson's disease(PD)reduce well-being of the patients.Emotional alterations influence motor skills and cognitive performance;moreover,they contribute significantly and independently to worsen rehabilitative treatment response.We investigated anxiety,depression,and quality of life in PD patients subjected to multidisciplinary rehabilitative training.The self-controlled study included 100 PD patients(49 males and 51 females with the mean age of 64.66 years)admitted to 60 days hospitalization rehabilitative program,between January 2017 and December 2018.Motor,cognitive,linguistic abilities,and functional independence were evaluated at admission(T0 baseline visit)and 60 days after(T1)the multidisciplinary rehabilitation including motor exercises,speech therapies,and cognitive intervention.The multidisciplinary rehabilitation improved functional status in PD patients and exerted its positive effects on mood,motor abilities,autonomy in the activities of daily life,perception of quality of life,cognitive performance and speech skills.Non-motor symptoms may worsen severe disability and reduce quality of life.They are often poorly recognized and inadequately treated.Nonetheless,multidisciplinary rehabilitative training represents an optimal strategy to improve disease management.The study was approved by Istituito di Ricovero e Cura a Carattere Scientifico(IRCCS)Centro Neurolesi"Bonino-Pulejo"Ethical Committee(approval No.6/2016)in June 2016.

During the past three decades, the Wingless-type MMTV integration site (Wnt) signaling cascade has emerged as an essential system regulating multiple processes in developing and adult brain. Accumulating evidence points to a dysregulation of Wnt signaling in major neurodegenerative pathologies including Parkinson's disease (PD), a common neurodegenerative disorder characterized by the progressive loss of midbrain dopaminergic (mDA) neurons and deregulated activation of astrocytes and microglia. This review highlights the emerging link between Wnt signaling and key inflammatory pathways during mDA neuron damage/repair in PD progression. In particular, we summarize recent evidence documenting that aging and neurotoxicant exposure strongly antagonize Wnt/β-catenin signaling in mDA neurons and subventricular zone (SVZ) neuroprogenitors via astrocyte-microglial interactions. Dysregulation of the crosstalk between Wnt/β-catenin signaling and anti-oxidant/anti-inflammatory pathways delineate novel mechanisms driving the decline of SVZ plasticity with age and the limited nigrostriatal dopaminergic self-repair in PD. These findings hold a promise in developing therapies that target Wnt/β-catenin signaling to enhance endogenous restoration and neuronal outcome in age-dependent diseases, such as PD.
