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...

OBJECTIVE: 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. In this study we quantified differences in the CD4/CD8 ratio, CD4% recovery and MTMR after starting HIV-1 treatment with DTG/ABC/3TC vs. EFV/TDF/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...

As other spiny lobsters, Panulirus argus is supposed to use preferentially proteins and lipids in energy metabolism, while carbohydrates are well digested but poorly utilized. The aim of this study was to evaluate the effect of dietary carbohydrate level on digestion and metabolism in the spiny lobster P. argus. We used complementary methodologies such as post-feeding flux of nutrients and metabolites, as well as measurements of α-amylase expression and activity in the digestive tract. Lobsters readily digested and absorbed carbohydrates with a time-course that is dependent on their content in diet...

INTRODUCTION: Diarrhea is a frequent complication in hematologic patients, being an infectious cause frequently suspected. Rapid and accurate detection of gastrointestinal pathogens is vital in immunocompromised hosts. The aim of this study was to compare routine diagnostic methods versus a multiplex polymerase chain reaction (PCR) assay for the diagnosis of infectious diarrhea in immunocompromised hematologic patients. MATERIAL AND METHODS: We conducted a prospective observational study from March 2015 to January 2016 to compare conventional methods for the diagnosis of infectious diarrhea with FIlmArray GI Panel (BioFire-bioMérieux, France)...

BACKGROUND: Debate persists over the association between blood transfusions, especially those considered discretionary, and outcomes after cardiac operations. Using data from the Maryland Cardiac Surgery Quality Initiative, we sought to determine whether outcomes differed among coronary artery bypass grafting (CABG) patients receiving 1 U of red blood cells (RBCs) vs none. METHODS: We used a statewide database to review patients who underwent isolated CABG from July 1, 2011, to June 30, 2016, across 10 Maryland cardiac surgery centers...

Alejo C Scarano, Bárbara Vera
Shape and age variation in dentition of Paleogene extinct native South American ungulates (Notoungulata) has been traditionally described using qualitative and quantitative approaches, and has played a controversial role in the systematics of several groups. Such is the case of the Notopithecidae, a group of notoungulates with low-crowned teeth, known from the middle Eocene of Patagonia (Argentina). In this group, as well as in other contemporary families, extreme morphological changes associated to increasing dental wear were originally assumed to represent taxonomic differences; thus, dozens of species were erected, clearly reflecting the difficulty of defining discrete characters...

We study the formation of caustic surfaces produced by conic lenses, considering a plane wavefront propagating parallel to the optical axis. The shape of the caustic can be modified by changing the parameters of the lens in such a way that if we are able to vanish the caustic, the optical system produces the sharpest diffraction-limited images. Alternatively, caustic surfaces with a large area can be applied to the design of non-imaging optical systems, with potential applications such as diffusers of light for illumination or solar concentrators...
