Time representation is a fundamental property of human cognition. Ample evidence shows that time (and numbers) are represented in space. However, how the conceptual mapping varies across individuals, scales, and temporal structures remains largely unknown. To investigate this issue, we conducted a large online study consisting in five experiments that addressed different time scales and topology: Zones of time, Seasons, Days of the week, Parts of the day and Timeline. Participants were asked to map different kinds of time events to a location in space and to determine their size and color...

Organic-inorganic hybrid halide perovskites compounds are emerging as new materials with great potential for efficient solar cells. This paper explores the possibility of increasing their photovoltaic efficiency through sub-bandgap absorption by way of the in gap band (IGB) concept. Thus, we assess the formation of an in gap band as well as its effect on the absorption features of Organic-inorganic hybrid halide perovskites CH3NH3PbI3 (MAPI). For this task, we use density functional theory (DFT) as well as many-body perturbation methods along to spin-orbit coupling (SOC) to study structural, energetic and electronic properties of partially Cr-substituted MAPI perovskites (CH3NH3Pb1-xCrxI3)...

PURPOSE: Breast cancer (BC) survivors are becoming increasingly predisposed to cardiovascular disease (CVD) mortality. Low cardiorespiratory fitness and physical activity (PA) levels, as well as high values of adiposity indices, contribute to CVD risk. We evaluated adiposity, cardiorespiratory profile, and PA levels in two independent cohorts of BC survivors. METHODS: Data were collected from two groups (99% women) from different areas of Madrid (Spain): group 1, n = 110, age 51...

The pluripotency-controlling stem-cell protein SRY-box 2 (SOX2) plays a pivotal role in maintaining the self-renewal and pluripotency of embryonic stem cells and also of teratocarcinoma or embryonic carcinoma cells. SOX2 is monomethylated at lysine 119 (Lys-119 or K119) in mouse embryonic stem cells by the SET7 methyltransferase, and this methylation triggers ubiquitin-dependent SOX2 proteolysis. However, the molecular regulators and mechanisms controlling SET7-induced SOX2 proteolysis are unknown. Here, we report that in human ovarian teratocarcinoma PA-1 cells, methylation-dependent SOX2 proteolysis is dynamically regulated by the LSD1 lysine demethylase and a methyl-binding protein, PHD finger protein 20-like 1 (PHF20L1)...

Lactate dehydrogenase (LDH) is key for anaerobic glycolysis. LDH is induced by the hypoxia inducible factor -1 (HIF-1). HIF-1 induces genes involved in glucose metabolism and regulates cellular oxygen homeostasis. HIF-1 is formed by a regulatory α-subunit (HIF-1α) and a constitutive β-subunit (HIF-1β). The white spot syndrome virus (WSSV) induces anaerobic glycolysis in shrimp hemocytes, associated with lactate accumulation. Although infection and lactate production are associated, the LDH role in WSSV-infected shrimp has not been examined...

Underwater visual census (UVC) is the most common approach for estimating diversity, abundance and size of reef fishes in shallow and clear waters. Abundance estimation through UVC is particularly problematic in species occurring at low densities and/or highly aggregated because of their high variability at both spatial and temporal scales. The statistical power of experiments involving UVC techniques may be increased by augmenting the number of replicates or the area surveyed. In this work we present and test the efficiency of an UVC method based on diver towed GPS, the Tracked Roaming Transect (TRT), designed to maximize transect length (and thus the surveyed area) with respect to diving time invested in monitoring, as compared to Conventional Strip Transects (CST)...

Haematopoiesis, the process of mature blood and immune cell production, is functionally organized as a hierarchy, with self-renewing haematopoietic stem cells and multipotent progenitor cells sitting at the very top. Multiple models have been proposed as to what the earliest lineage choices are in these primitive haematopoietic compartments, the cellular intermediates, and the resulting lineage trees that emerge from them. Given that the bulk of studies addressing lineage outcomes have been performed in the context of haematopoietic transplantation, current models of lineage branching are more likely to represent roadmaps of lineage potential than native fate...

We read with great interest the paper by Navarrete-Dechent et al recently published on the Journal of European Academy of Dermatology1 , in which the authors detail the dermoscopic findings of trichobacteriosis and highlight the importance of dermoscopy in these cases. We present the case of a 44-year-old man, who emanated an unpleasant axilary odor during a routine check-up. Close examination of the axillary hair shafts showed soft, brown to yellow irregular masses adherent to the central segment of the hairs, suggesting the diagnosis of trichobacteriosis axilaris (TA)...

We report on the first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam. Strong magnetic fields (≥1  T) are measured, via means of a proton radiography technique, after the propagation of a neutral electron-positron beam through a background electron-ion plasma. The experimentally determined equipartition parameter of ε_{B}≈10^{-3} is typical of values inferred from models of astrophysical gamma-ray bursts, in which the relativistic flows are also expected to be pair dominated...

OBJECTIVES: CD4/CD8 ratio and CD4+ T-cell percentage (CD4%) predicts the risk of AIDS and non-AIDS events. Multiple T-cell marker recovery (MTMR) has been proposed as the most complete level of immune reconstitution. We quantified differences in the CD4/CD8 ratio, CD4% recovery and MTMR after starting HIV-1 treatment with dolutegravir/abacavir/lamivudine vs. efavirenz (EFV)/tenofovir (TDF)/emtricitabine (FTC). METHODS: Exploratory post hoc analysis of the SINGLE study, a randomized double-blind, clinical trial...

The objective of this research is to characterize the variability of trace metals in the Rio Santa watershed based on synoptic sampling applied at a large scale. To that end, we propose a combination of methods based on the collection of water, suspended sediments, and riverbed sediments at different points of the watershed within a very limited period. Forty points within the Rio Santa watershed were sampled between June 21 and July 8, 2013. Forty water samples, 36 suspended sediments, and 34 riverbed sediments were analyzed for seven trace metals...

BACKGROUND: Historically, the "temporary" or short-term ventricular assist device (VAD) was used only as a quick bridge to recovery for children with an acute process. In the current era, the devices that were originally used for temporary support are now being used to support children for longer durations and for a variety of indications. In this study we aimed to describe the overall use, patients' characteristics and outcomes of "temporary" VAD use in children. METHODS: The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a National Institutes of Health-supported national registry for United States Food and Drug Administration-approved VADs in patients <19 years of age at the time of VAD implantation (either durable or temporary VAD)...

In this paper, we analyze how a political blog author (Spanish Alejo Vidal-Quadras) establishes the reference to self and other in his blog entries. We furthermore look into how the commentators to this blog react and establish reference to self and other in the digital public sphere. More concretely, we show that they not only take up the references established by the main blog author but also create new references. These allow, on the one hand, for profiling themselves as part of a group and, on the other hand, identifying their interlocutor among the variety of possible interlocutors in the digital public sphere...

The present study verified if the translational component of locomotion modulated cortical activity recorded at action observation. Previous studies focusing on visual processing of biological motion mainly presented point light walker that were fixed on a spot, thus removing the net translation toward a goal that yet remains a critical feature of locomotor behavior. We hypothesized that if biological motion recognition relies on the transformation of seeing in doing and its expected sensory consequences, a significant effect of translation compared to centered displays on sensorimotor cortical activity is expected...

Common photosensitizers used in photodynamic therapy do not penetrate the skin effectively. In addition, the visible blue and red lights used to excite such photosensitizers have shallow penetration depths through tissue. To overcome these limitations, we have synthesized ultraviolet and visible light emitting, energy-transfer based upconversion nanoparticles, and co-encapsulated them inside PLGA-PEG nanoparticles with photosensitizer protoporphyrin IX. Nd3+ has been introduced as sensitizer in the upconversion nanostructures to allow their excitation at 808 nm...

INTRODUCTION: It was observed that women with aneurysmal subarachnoid hemorrhage (aSAH) tended to have earlier menses than a typical 21- to 28-day cycle. The goal was to determine whether there is an association between aSAH and early onset of menses. METHODS: All cases of aSAH in women aged 18 to 55 years who were admitted to our facility's neuroscience intensive care unit from June 1, 2011, to June 30, 2012, were reviewed. The electronic healthcare record for each of these patients was examined for documentation of menses onset, computed tomography of the head, brain aneurysm characteristics, modified Fisher score and Glasgow Coma Scale on admission, presence/absence of vasospasm, medical/surgical history, and use of medications that affect the menstrual cycle...
