Pseudothrombocytopenia: a case of platelet satellitism and phagocytosis by neutrophils.

Thrombocytopenia is a clinically important condition that can lead to several problems when not correctly diagnosed. A decrease of platelet counts due to an phenomenon, Pseudothrombocytopenia, can be misunderstood and unnecessarily treated. The present case study describes a 57-year-old male with a history of pancreas adenocarcinoma and a current infection without any signs or symptoms that could explain the low levels of platelets obtained after blood analysis.

Distinct Phenotypic and Genomic Signatures Underlie Contrasting Pathogenic Potential of Clonal Lineages.

is a common skin commensal that has emerged as a pathogen in hospitals, mainly related to medical devices-associated infections. Noteworthy, infection rates by have the tendency to rise steeply in next decades together with medical devices use and immunocompromized population growth. population structure includes two major clonal lineages (A/C and B) that present contrasting pathogenic potentials.

underlies the evolution of male genital morphology.

Male genital structures are among the most rapidly evolving morphological traits and are often the only features that can distinguish closely related species. This process is thought to be driven by sexual selection and may reinforce species separation. However, while the genetic bases of many phenotypic differences have been identified, we still lack knowledge about the genes underlying evolutionary differences in male genital organs and organ size more generally.

Acute appendicitis may no longer be a predominant disease of the young population.

Background: Some authors consider acute appendicitis as the main cause of acute surgical abdomen. Incident in all ages, contemporary literature suggests that is more frequent in children and young adults, male predominantly. This study aims to test the hypothesis that the disease in question is no longer prevalent in young adults (excluding children) in the surveyed region.

Technical approaches to evaluate the surfactant-enhanced biodegradation of biodiesel and vegetable oils.

This research compared the effects of biosurfactant on the biodegradation of biodiesel and vegetable oils while validating two conceptually diverging methodologies. The two experimental setups were successfully modeled towards the effects of biosurfactants during biodegradation. We established the equivalence of both methodologies from the data output.

Access to healthcare for children with Congenital Zika Syndrome in Brazil: perspectives of mothers and health professionals.

The Congenital Zika Syndrome (CZS) epidemic took place in Brazil between 2015 and 2017 and led to the emergence of at least 3194 children born with CZS. We explored access to healthcare services and activities in the Unified Health Service (Sistema Único de Saúde: SUS) from the perspective of mothers of children with CZS and professionals in the Public Healthcare Network. We carried out a qualitative, exploratory study, using semi-structured interviews, in two Brazilian states-Pernambuco, which was the epicentre of the epidemic in Brazil, and Rio de Janeiro, where the epidemic was less intense.

Decay of the distance autocorrelation and Lyapunov exponents.

This work presents numerical evidence that for discrete dynamical systems with one positive Lyapunov exponent the decay of the distance autocorrelation is always related to the Lyapunov exponent. Distinct decay laws for the distance autocorrelation are observed for different systems, namely, exponential decays for the quadratic map, logarithmic for the Hénon map, and power-law for the conservative standard map. In all these cases the decay exponent is close to the positive Lyapunov exponent.

A social rank approach to disordered eating: Exploring relationships between shame, fears of compassion, striving, and body shame.

Objectives: The impact of a social rank mentality on eating-related difficulties has been previously recognized, although mediating processes involved remain to be clarified. The current study aimed to explore the roles of insecure striving and body image shame on the relationships between external shame and fears of receiving compassion from others with eating difficulties, while controlling for BMI effects.

Methods: A total of 335 women from the general population participated in this study, aged between 18 and 62 years, who completed an investigation protocol, with self-report measures.

The addition of a quaternary group in biopolymeric material increases the adsorptive capacity of Acid Blue 25 textile dye.

The quaternization of chitosan molecules creates materials with high adsorptive capacity towards textile dyes, which renders them capable of rapidly removing such dyes from a solution. In this study, a novel material was synthesized in bead form to adsorb the Acid Blue 25 textile dye. The adsorption isotherms, kinetics, and thermodynamics of this new material were investigated.

Enteric glial cells immunoreactive for P2X7 receptor are affected in the ileum following ischemia and reperfusion.

The aim of this study was to analyze the effect of ischemia and reperfusion injury (IS) on enteric glial cells (EGCs) and neurons immunoreactive for the P2X7 receptor. Intestinal ischemia was induced by obstructing blood flow in the ileal vessels for 35 min. Afterwards, the vessels were reperfused for 14 days.

ATLANTIC MAMMALS: a data set of assemblages of medium- and large-sized mammals of the Atlantic Forest of South America.

Biodiversity inventories contain important information about species richness, community structure, and composition, and are the first step in developing any conservation and mitigation strategies. The Atlantic Forest of South America is home to around 334 species of small-, medium-, and large-sized mammals, and is currently restricted to less than 12% of its original cover. Here, we present the ATLANTIC MAMMALS, an open data set on information on medium- and large-sized mammal assemblages in the Atlantic Forest of Brazil, Paraguay, and Argentina.

The evaluation of the potential ecotoxicity of pyroligneous acid obtained from fast pyrolysis.

Pyroligneous acid (PA) is a by-product of bio-oil, which is obtained by pyrolysis of the wood. This product has been tested for use in several areas, such as agriculture, as a promising green herbicide; however, there are few scientific data regarding its environmental impacts. For this study, an ecotoxicity testing battery, composed of Daphnia magna acute toxicity test, Allium cepa test and in vitro Comet assay with the rainbow trout gonad-2 cell fish line (RTG-2) were used to evaluate the acute toxicity and genotoxicity of PA obtained from fast pyrolysis of eucalyptus wood fines.

Sevoflurane Preconditioning plus Postconditioning Decreases Inflammatory Response with Hemodynamic Recovery in Experimental Liver Ischemia Reperfusion.

Objective: The inhalation anesthetic sevoflurane has presented numerous biological activities, including anti-inflammatory properties and protective effects against tissue ischemic injury.

Clinical and laboratory features of African-Brazilian patients with systemic sclerosis.

Objective: African-Brazilians comprise a group of blacks and "pardos." As racial differences can be associated with distinct presentations, we evaluated the clinical and serological associations of African-Brazilians with systemic sclerosis (SSc).

Methods: Sera from 260 adult SSc patients (203 whites and 57 African-Brazilians) were evaluated.

Evidence of Aquaporin 4 Regulation by Thyroid Hormone During Mouse Brain Development and in Cultured Human Glioblastoma Multiforme Cells.

Accumulating evidence indicates that thyroid function and the thyroid hormones L-thyroxine (T4) and L-triiodothyronine (T3) are important factors contributing to the improvement of various pathologies of the central nervous system, including stroke, and various types of cancer, including glioblastoma multiforme (GBM). Low levels of T3 are correlated with the poorest outcome of post-stroke brain function, as well as an increased migration and proliferation of GBM tumor cells. Thyroid hormones are known to stimulate maturation and brain development.

Insecure striving as an exacerbator of the toxic effect of shame feelings on disordered eating.

Background: Empirical evidence has previously shown the impact of shame and insecure striving on the emergence of eating psychopathology. However, interactions between these variables and the development of pathological eating remain unclear.

Objective: The present study aimed at exploring the moderator effect of insecure striving on the relationship between shame and disordered eating, while controlling for BMI effects.

Insulin treatment protects the brain against neuroinflammation by reducing cerebral cytokines and modulating mitochondrial function.

In the central nervous system, glial cells protect the brain against neuronal stress by inducing inflammatory responses; namely, intracellular signaling and cytokine production. However, chronic inflammation is often associated with degenerative diseases that can damage hormone signaling and mitochondrial function. Lipopolysaccharide (LPS) induces neuroinflammation by stimulating the production of interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α); moreover, it generates oxidative stress and impairs cognitive functions.

Diagnostic accuracy of thromboelastometry and its correlation with the HPLC-MS/MS quantification test.

The aim of the study was to evaluate the diagnostic accuracy of thromboelastometry for assessing rivaroxaban concentrations. The accuracy of thromboelastometry was compared with the high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) method, which is the gold standard for drug plasma monitoring (the reference standard). Forty-six clinically stable patients were treated with 10, 15, or 20 mg of rivaroxaban once daily (OD group) or 15 mg twice a day (BID group) (no particular indication for treatment).

Localization-delocalization transition in discrete-time quantum walks with long-range correlated disorder.

We study the effects of spatially long-range correlated phase disorder on the Hadamard quantum walk on a line. The shift operator is built to exhibit an intrinsic disorder distribution featuring long-range correlations. To impose such, we resort to fractional Brownian motion with power-law spectrum 1/k^{2α} with α≥0 being the exponent that controls the degree of correlations.
