The clinical behavior of systemic mastocytosis (SM) is strongly associated with activating mutations in KIT (D816V in >80% of cases), with the severity of the phenotype influenced by additional somatic mutations, e.g. in SRSF2, ASXL1 or RUNX1. Complex molecular profiles are frequently associated with the presence of an associated hematologic neoplasm (AHN) and an unfavorable clinical outcome. However, little is known about the incidence and prognostic impact of cytogenetic aberrations. We analyzed cytogenetic and molecular characteristics of 109 patients (KIT D816V+, n=102, 94%) with indolent (ISM, n=26) and advanced SM (n=83) with (n=73, 88%) or without AHN...

Prosopis juliflora was introduced in northeastern Brazil in the 1940s, and since then, it has been available as an alternative for animal nutrition. However, the consumption of P. juliflora as main or sole source of food causes an illness in animals known locally as "cara torta" disease. Cattle and goats experimentally intoxicated presents neurotoxic damage in the central nervous system. Histologic lesions were mainly characterized by vacuolation and loss of neurons in trigeminal motor nuclei. Furthermore, mitochondrial damage in neurons and gliosis was reported in trigeminal nuclei of intoxicated cattle...

Sporotrichosis is the most prevalent subcutaneous mycosis and is characterized by a subacute or chronic development of a cutaneous or subcutaneous nodular lesion. It is caused by the dimorphic fungus Sporothrix spp, which may manifest in different clinical forms. The disseminated cutaneous form is uncommon and is more likely to occur in immunocompromised patients. We report a 47-year-old male patient with multiple cutaneous and subcutaneous nodules. The patient was diagnosed with disseminated cutaneous sporotrichosis based on the isolation and identification of Sporothrix spp...

Autoimmune retinopathy (AIR) is a rare and still poorly understood immune-mediated disease that may cause inflammation from circulating autoantibodies against the retina. It may be related to history of autoimmune disease in the patient or in a family member or the presence of neoplastic disease in the individual. The disease may be subdivided into paraneoplastic and non-paraneoplastic AIR. When related to melanoma, it is referred to as MAR, and when related to other cancers, it is called CAR. The exact prevalence of AIR is unknown...

Breast cancer remains the most prevalent cause of cancer mortality in woman worldwide due to the metastatic process and therapy resistance. Resistance against cancer therapy is partially attributed to cancer stem cells (CSCs). These cells arise from epithelial cells undergoing epithelial-to-mesenchymal transition (EMT) and might be responsible for tumor recurrence. In this study, we reported the relevance of miR-155 upregulation in chemoresistant cells associated with EMT. Notably, we found miR-155 induction in exosomes isolated from CSCs and resistant cells, followed by resistant cells' exosome transfer to the recipient sensitive cells...

Protease/anti-protease imbalance is the main pathogenic mechanism of emphysema and protease inhibitors have been recognized as potential molecules to treat the disease conditions. In this work the rBmTI-6 first domain (rBmTI-6-D1), a recombinant Kunitz-type serine proteinase inhibitor, was used to verify its effect in prevention or minimization of PPE-induced emphysema in mice. C57BL/6 mice were submitted to a PPE-induced emphysema model and treated with rBmTI-6-D1 before the emphysema development. We showed that the rBmTI-6-D1 treatment was sufficient to avoid the loss of elastic recoil, an effective decrease in alveolar enlargement and in the number of macrophages and lymphocytes in bronchoalveolar lavage fluid...

BACKGROUND: Mitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation can generate more efficient coupling of energy production. However, selection over mitochondrial DNA (mtDNA) genes has usually been evaluated at the population level. We sequenced by NGS 12 mitogenomes and with four published genomes, assessed genetic variation in ten penguin species distributed from the equator to Antarctica...

Although most Brazilian dairy products meet high technological standards, there are quality issues regarding milk production, which may reduce the final product quality. Several microbial species may contaminate milk during manufacture and handling. If antimicrobial usage remains uncontrolled in dairy cattle, the horizontal transfer of antimicrobial resistance genes in foodstuffs may be of particular concern for both food producers and dairy industry. This study focused on the evaluation of putative Gram positive cocci in Minas cheese and of antimicrobial and biocide resistance genes among the isolated bacteria...

Fungi are considered the most damaging microorganisms in agriculture. The indiscriminate use of chemical treatments in agricultural products causes the development of pest resistance and affects human health. An alternative to synthetic fungicides is the use of natural products such as plant extracts for the management of fungal diseases in plants. Extracts from different parts of Lupinus albescens (roots, stalks, leaves, and flowers) were obtained by extraction using supercritical carbon dioxide (CO2) or compressed liquefied petroleum gas (LPG)...

The complement system is essential for host defense, but uncontrolled complement system activation leads to severe, mostly renal pathologies, such as atypical hemolytic uremic syndrome or C3 glomerulopathy. Here, we investigated a novel combinational approach to modulate complement activation by targeting C3 and the terminal pathway simultaneously. The synthetic fusion protein MFHR1 links the regulatory domains of complement factor H (FH) with the C5 convertase/C5b-9 inhibitory fragment of the FH-related protein 1...

A Disintegrin And Metalloprotease 17 (ADAM17) modulates signaling events by releasing surface protein ectodomains such as TNFα and the EGFR-ligands. We have previously characterized cytoplasmic thioredoxin-1 (Trx-1) as a partner of ADAM17 cytoplasmic domain. Combining discovery and targeted proteomic approaches, we uncovered that Trx-1 negatively regulates ADAM17 by direct and indirect effect. We performed cell-based assays with synthetic peptides and site-directed mutagenesis and we demonstrated that the interaction interface of Trx-1 and ADAM17 is important for the negative regulation of ADAM17 activity...

INTRODUCTION: The management of anxious patients undergoing dental procedures is still a challenge in clinical practice. Despite a wide variety of drugs for oral sedation in adult patients, there are relatively few systematic reviews that compare the effectiveness and safety of different drugs administered via this route. Thus, this study will evaluate the effectiveness and safety of oral sedation with benzodiazepines and other agents to patients undergoing dental surgical procedures...

BACKGROUND: Obsessive-Compulsive Disorder (OCD) is a complex and chronic disorder characterized by recurrent thoughts and/or repetitive behaviors. Given the potent anti-obsessional effects of the so-called serotonin reuptake inhibitors, genes related to serotonergic system may be well implicated in the etiopathogenesis of OCD. The gene encoding the serotonin transporter (SLC6A4), which shows a variable number of tandem repeat (VNTR) polymorphism in intron 2 (STin2), have been previously associated with OCD...

Deposition of amyloid-β (Aβ), the proteolytic product of the amyloid precursor protein (APP), might cause neurodegeneration and cognitive decline in Alzheimer's disease (AD). However, the direct involvement of APP in the mechanism of Aβ-induced degeneration in AD remains on debate. Here, we analyzed the interaction of APP with heterotrimeric Go protein in primary hippocampal cultures and found that Aβ deposition dramatically enhanced APP-Go protein interaction in dystrophic neurites. APP overexpression rendered neurons vulnerable to Aβ toxicity by a mechanism that required Go-Gβγ complex signaling and p38-mitogen-activated protein kinase activation...

Allogeneic hematopoietic stem cell transplantation (HSCT) is the only treatment that enhances survival and stabilizes neurologic symptoms in X-linked adrenoleukodystrophy (X-ALD) with cerebral involvement, a severe demyelinating disease of childhood. Patients with X-ALD who lack a well-matched HLA donor need a rapid alternative. Haploidentical HSCT using post transplant cyclophosphamide (PT/Cy) has been performed in patients with malignant and nonmalignant diseases showing similar outcomes compared to other alternative sources...
