The burden of neurocognitive impairment (NCI) in patients receiving maintenance dialysis represents a spectrum of deficits across multiple cognitive domains which are associated with hospitalisation, reduced quality-of-life, mortality and forced decision-making around dialysis withdrawal. Point prevalence data suggests that dialysis patients manifest NCI at rates 3-5 fold higher than the general population with executive function the most commonly affected cognitive domain. The unique physiology of the renal failure state and maintenance dialysis appears to drive an excess of vascular dementia subtype compared to the general population where classical Alzheimer's disease predominates...

Objectives Strategies were explored to improve patient adherence to cardioprotective medications by borrowing from a motivational framework used in psychology, regulatory focus theory. The current study is part of a larger randomized control trial and was aimed at understanding what written educational messages, based on patients' regulatory focus tendency, resonated with each individual as a potential reminder to take medications. This study was also aimed at understanding why messages resonated with the patients...

BACKGROUND: The pathogenesis of vitiligo remains a topic of extensive debate. This is partly due to the moderate efficacy of current treatments. The role of oxidative stress pathway in vitiligo is a popular although controversial research topic. OBJECTIVE: To clarify the role of the oxidative stress pathway in vitiligo compared to other inflammatory skin disorders and to assess the therapeutic role of antioxidants. METHODS: We conducted a systematic search of the existing literature on the aberrancies of the oxidative stress pathway in vitiligo...

We show that carbon-based nanostructured materials are a novel testbed for controlling thermoelectricity and have the potential to underpin the development of new cost-effective environmentally-friendly thermoelectric materials. In single-molecule junctions, it is known that transport resonances associated with the discrete molecular levels play a key role in the thermoelectric performance, but such resonances have not been exploited in carbon nanotubes (CNTs). Here we study junctions formed from tapered CNTs and demonstrate that such structures possess transport resonances near the Fermi level, whose energetic location can be varied by applying strain, resulting in an ability to tune the sign of their Seebeck coefficient...

Mucosal-associated invariant T (MAIT) cells are semi-invariant Vα7.2+ CD161highCD4- T cells that recognize microbial riboflavin precursor derivatives such as 5-OP-RU presented by MR1. Human MAIT cells are abundant in adult blood, but there are very few in cord blood. We longitudinally studied Vα7.2+ CD161high T cell and related subset levels in infancy and after cord blood transplantation. We show that Vα7.2+ and Vα7.2- CD161high T cells are generated early during gestation and likely share a common prenatal developmental program...

Dysregulated mitophagy has been linked to Parkinson's disease (PD) due to the role of PTEN-induced kinase 1 (PINK1) in mediating depolarization-induced mitophagy in vitro. Elegant mouse reporters have revealed the pervasive nature of basal mitophagy in vivo, yet the role of PINK1 and tissue metabolic context remains unknown. Using mito-QC, we investigated the contribution of PINK1 to mitophagy in metabolically active tissues. We observed a high degree of mitophagy in neural cells, including PD-relevant mesencephalic dopaminergic neurons and microglia...

METHODS: We present a rare case with atypical presenting features of unilateral CPEO with a false positive Acetylcholine Receptor Antibody (AchRA) test resulting in diagnostic delay. We illustrate the unilateral nature of this case and demonstrate the caveats of performing myogenic ptosis correction in such patients. We also discuss the differential diagnosis of false positive AchRA, a test commonly performed in the investigation of ptosis. RESULTS: A 34-year old female presented with a more than 3-year history of slowly-progressive, unilateral, right-sided restriction in eye movements and ptosis...

The aim of this project is to gain insights into the uptake and cellular actions of the enantiomeric R- and S-1,1'-binaphthyl-2,2'-diaminodichlorido-Pt(ii) complexes (R- and S-[Pt(DABN)Cl2]) in the cisplatin-sensitive human Burkitt lymphoma cell line (Gumbus, IC50: 1.3 ± 0.2 μM) and its cisplatin-resistant sub-line (CDDPrGB, IC50: 6.6 ± 1.2 μM). The cellular uptakes of R- and S-[Pt(DABN)Cl2] are ca. 4-fold higher than cisplatin, and involve a transport mechanism independent of the volume-sensitive, organic anion-channel complex, which facilitates cisplatin accumulation...

The use of solar energy to power chemical reactions is a long-standing dream of the chemical community. Recently, visible-light-mediated photoredox catalysis has been recognized as the ideal catalytic transformation to convert solar energy into chemical bonds. However, scaling photochemical transformations has been extremely challenging due to Bouguer-Lambert-Beer law. Recently, we have pioneered the development of luminescent solar concentrator photomicroreactors (LSC-PMs), which display an excellent energy efficiency...

This article reports findings from a participative and qualitative study conducted with children who had experienced domestic violence, focusing on their perspectives on their relationships with their mothers. Three focus groups and 46 individual interviews were conducted with children to gather their experiences. The research findings demonstrate that women's and children's victimizations are inextricably linked, and that domestic violence affects mother-child relationships. They also show that, despite the challenges and difficulties, children generally consider their mothers as very significant individuals in their lives, and have close relationships with them...

Terminal branches of the superficial fibular nerve are at risk of iatrogenic damage during foot surgery, including hallux valgus rigidus correction, bunionectomy, cheilectomy, and extensor hallucis longus tendon transfer. One terminal branch, the dorsomedial cutaneous nerve of the hallux, is particularly at risk of injury at its intersection with the extensor hallucis longus tendon. Iatrogenic injuries of the dorsomedial cutaneous nerve of the hallux can result in sensory loss, neuroma formation, and/or debilitating causalgia...

Ecosystem fragmentation is a serious threat to biodiversity and one of the main challenges in ecosystem restoration. River continuity restoration (RCR) has often targeted diadromous fishes, a group of species supporting strong cultural and economic values and especially sensitive to river fragmentation. Yet it has frequently produced mixed results and diadromous fishes remain at very low levels of abundance. Against this background, this paper presents the main challenges for defining, evaluating and achieving effective RCR...

This pilot study pursued three objectives: to assess the effect of a 1-month multilevel intervention on the PA of children, to assess the impact of the intervention on the theory of planned behavior (TPB) variables, and to evaluate the extent to which the impact of the intervention on PA and TPB variables varied according to personal (i.e., gender and age) and situational (i.e., class and school) moderating variables. Children were aged 7 to 11 years ( n = 306). Analyses revealed a significant increase of PA practice and TPB variables ( ps < ...

Acute myocardial infarction (MI) triggers an adverse increase in cardiac sympathetic nerve activity (SNA). While β-adrenergic receptor (β-AR)-blockers are routinely used for the management of MI, they may also counter β-AR-mediated vasodilation of coronary vessels. We have reported that ghrelin prevents sympathetic activation following MI. Whether ghrelin modulates coronary vascular tone following MI, either through the modulation of SNA, or directly as a vasoactive mediator, has never been addressed.We utilized synchrotron microangiography to image coronary perfusion and vessel internal diameter (ID) in anesthetized Sprague Dawley rats before, and then again 30 mins after induction of an MI (left coronary artery ligation)...

During inattentive wakefulness and non-rapid eye movement (NREM) sleep, the neocortex and thalamus cooperatively engage in rhythmic activities that are exquisitely reflected in the electroencephalogram as distinctive rhythms spanning a range of frequencies from <1 Hz slow waves to 13 Hz alpha waves. In the thalamus, these diverse activities emerge through the interaction of cell-intrinsic mechanisms and local and long-range synaptic inputs. One crucial feature, however, unifies thalamic oscillations of different frequencies: repetitive burst firing driven by voltage-dependent Ca2+ spikes...
