Previous works have studied structural brain characteristics in first-episode psychosis (FEP), but few have focused on the relation between brain differences and illness trajectories. The aim of this study is to analyze gray and white matter changes in FEP patients and their relation with one-year clinical outcomes. A sample of 41 FEP patients and 41 healthy controls (HC), matched by age and educational level was scanned with a 3T MRI during the first month of illness onset. One year later, patients were assigned to two illness trajectories (schizophrenia and non-schizophrenia)...

Ecologists aim at disentangling how species vary in abundance through spatial and temporal scales, using a range of sampling techniques. Here, we investigated the circadian rhythm of seagrass-associated decapod crustaceans through three sampling techniques. Specifically, we compared the abundance, biomass and structure of seagrass-associated decapod assemblages between the day and night using a hand net, an airlift pump and baited traps. At night, the hand-net consistently collected a larger total abundance and biomass of decapods, what resulted in significant diel differences, which were detected for the total biomass, but not for the total abundance, when decapods were sampled through an airlift pump...

The high levels of oxidative stress and inflammation can be present in the etiology of degenerative intestinal pathologies associated with ethanol ingestion. The Rosmarinus officinalis L. has exhibited several physiological and medicinal activities. In this investigation, we intended to clarify, for the first time, the antioxidant and anti-inflammatory effects of ethanolic extract of Rosmarinus officinalis L. (eeRo) against an acute damage induced by ethanol, specifically in the small intestine of rats. The rats were treated three times, at every 24 h, with eeRo at 500-1000 mg/kg or vehicle, oral gavage...

BACKGROUND: Thrombocytopenia is a life-threatening complication in patients with advanced myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML). In this study (ASPIRE), we aimed to assess eltrombopag, an oral thrombopoietin receptor agonist, for thrombocytopenia (grade 4) treatment in adult patients with advanced MDS or AML. METHODS: ASPIRE consisted of an open-label, double-blind phase for 8 weeks and a randomised, double-blind phase (parts 1 and 2, reported here) for 12 weeks, and an open-label extension (part 3)...

In our ongoing pursuit of CXCR4 antagonists as potential anticancer agents, we recently developed a potent, selective and plasma stable peptide, Ac-Arg-Ala-[D-Cys-Arg-Phe-Phe-Cys]-COOH (3). Nevertheless, this compound was still not enough potent (IC50 ≈ 53 nM) to enter preclinical studies. Thus, a lead-optimization campaign was here undertaken to further improve the binding affinity of 3 while preserving its selectivity and proteolytic stability. Specifically, extensive structure-activity relationships (SARs) investigations were carried out on both its aromatic and disulfide forming amino acids...

PGD for HLA typing is a procedure that can be performed when an affected child requires a transplant to treat a non-hereditary disorder related to the hematopoietic and/or immune system. Hematopoietic stem cell transplantation from an HLA-identical donor provides the best treatment option. Three conventional ovarian stimulation procedures for IVF were performed in a couple with a 10-year-old child diagnosed with T-cell acute lymphoblastic leukemia of high risk. Trophectoderm biopsy and aCGH examination were performed on 15 blastocysts, three on the first IVF procedure, four on the second cycle, and eight on the third...

The use of a Kerr nonlinearity to generate squeezed light is a well-known way to surpass the quantum noise limit along a given field quadrature. Nevertheless, in the most common regime of weak nonlinearity, a single Kerr resonator is unable to provide the proper interrelation between the field amplitude and squeezing required to induce a sizable deviation from Poissonian statistics. We demonstrate experimentally that weakly coupled bosonic modes allow exploration of the interplay between squeezing and displacement, which can give rise to strong deviations from the Poissonian statistics...

In phase 2/3 trials, eltrombopag treatment of 6 months or less in patients with chronic/persistent immune thrombocytopenia (ITP) increased platelet counts and reduced bleeding. The open-label EXTEND study evaluated long-term safety and efficacy of eltrombopag in adults with ITP who had completed a previous eltrombopag study. For the 302 patients enrolled, median duration of eltrombopag treatment was 2.37 years (2 days-8.76 years). Median platelet counts increased to 50 × 109/L or more by week 2 and were sustained throughout the treatment period...

Cognitive symptoms play a central role in schizophrenia and are strongly associated with social functioning. Treatment with clozapine presents controversial results regarding its effects on cognition. The opposite effects of clozapine and n-desmethylclozapine (NDMC) on cholinergic system have been suggested to underlie these inconclusive findings. The aim of this study is to determine whether clozapine/NDMC ratio can predict cognitive performance in patients with treatment-resistant psychosis. Nineteen clinically stable patients with schizophrenia or schizoaffective disorder treated with clozapine monotherapy completed demographic and clinical interviews...

This text is a theoretical essay that discusses the concepts, types and scenarios of feminicides, and presents some proposals for the prevention of these premature, unjust and avoidable deaths. The text revisits the original concept of femicide proposed by Diana Russell and Jane Caputti and shows new and old scenarios where these crimes occur. It points to patriarchy, understood as being a hierarchical system of power between men and women, as one of the main determinants of these deaths. It ends by presenting actions and proposals to prevent and combat these gender crimes...

Sporotrichosis is a polymorphic chronic infection of humans and animals classically acquired after traumatic inoculation with soil and plant material contaminated with Sporothrix spp. propagules. An alternative and successful route of transmission is bites and scratches from diseased cats, through which Sporothrix yeasts are inoculated into mammalian tissue. The development of a murine model of subcutaneous sporotrichosis mimicking the alternative route of transmission is essential to understanding disease pathogenesis and the development of novel therapeutic strategies...

BACKGROUND: Abnormalities in the hippocampus have been implicated in the pathophysiology of psychosis. However, it is still unclear whether certain abnormalities are a pre-existing vulnerability factor, a sign of disease progression or a consequence of environmental factors. We hypothesized that first-episode psychosis patients who progress to schizophrenia after one year of follow up will display greater volumetric and morphological changes from the very beginning of the disorder. METHODS: We studied the hippocampus of 41 patients with a first-episode psychosis and 41 matched healthy controls...
