NO-cGMP-K Channels Pathways Participate in the Antihypertensive Effects of Martius ex Spreng Oil-Loaded Nanocapsules.

Martius ex Spreng is a palm tree that is widely distributed in the Central-West region of Brazil. In this study, we investigated whether the oil-loaded nanocapsules of (APON) have acute and long-lasting antihypertensive effects in male spontaneously hypertensive rats (SHR), as well as explored the underlying molecular mechanisms. APON was prepared using the interfacial polymer deposition method.

Clinicopathological characteristics of endometrial carcinomas according to DNA mismatch repair protein status.

DNA mismatch repair protein deficiency (MMRd) in endometrial carcinoma is associated with the risk of Lynch syndrome and response to immune checkpoint inhibitors. It is also related to microsatellite instability and corresponds to a molecular subtype of endometrial tumor with an unclear prognosis. Here, we evaluated the clinicopathological characteristics and prognosis of 312 consecutive endometrial carcinoma cases submitted to complete surgical staging at a single institution.

Natural Products as Modulators of Mitochondrial Dysfunctions Associated with Cardiovascular Diseases: Advances and Opportunities.

The mitochondria have an important role in modulating cell cycle progression, cell survival, and apoptosis. In the adult heart, the cardiac mitochondria have a unique spatial arrangement and occupy nearly one-third the volume of a cardiomyocyte, being highly efficient for converting the products of glucose or fatty acid metabolism into adenosine triphosphate (ATP). In cardiomyocytes, the decline of mitochondrial function reduces ATP generation and increases the production of reactive oxygen species, which generates impaired heart function.

Evidence of the Cardioprotective Effects of in Isoproterenol-Induced Myocardial Infarction in Rats.

is a plant species that is widely used in Brazilian folk medicine for the treatment of different disorders that affect the cardiovascular system. The aim of the study was to investigate the cardioprotective effects of an ethanol-soluble fraction of (ESAP) on isoproterenol-induced myocardial infarction in rats. Different groups of rats ( = 8) were orally treated with ESAP (30, 100, and 300 mg/kg), carvedilol (10 mg/kg), or vehicle (filtered water; 1 mL/100 g) for 7 days.

MHC Class I Stability is Modulated by Cell Surface Sialylation in Human Dendritic Cells.

Maturation of human Dendritic Cells (DCs) is characterized by increased expression of antigen presentation molecules, and overall decreased levels of sialic acid at cell surface. Here, we aimed to identify sialylated proteins at DC surface and comprehend their role and modulation. Mass spectrometry analysis of DC's proteins, pulled down by a sialic acid binding lectin, identified molecules of the major human histocompatibility complex class I (MHC-I), known as human leucocyte antigen (HLA).

Fluorescein Angiography Findings in Children With Congenital Zika Syndrome.

Background And Objective: To evaluate the retinal and vasculature changes in infants with congenital Zika syndrome (CZS) using fluorescein angiography (FA).

Patients And Methods: This consecutive case series included six infants with CZS. FA and color fundus imaging were performed under general anesthesia in both eyes of all infants using a contact widefield digital imaging system.

Vitexin inhibits inflammation in murine ovalbumin-induced allergic asthma.

Vitexin is an important component of various medicinal plants frequently used to treat asthma, such as Crataegus spp., Vitex spp., Passiflora spp.

Hydroethanolic extract from Echinodorus scaber Rataj leaves inhibits inflammation in ovalbumin-induced allergic asthma.

Ethnopharmacological Relevance: Echinodorus scaber, Alismataceae, is popularly known in Brazil as "chapéu-de-couro". The plant leaves are used by the population as decoction, infusion, or maceration in bottled spirits, to treat inflammatory respiratory diseases.

Aim Of The Study: To investigate the anti-inflammatory mechanism of the hydroethanolic extract of leaves of Echinodorus scaber (HEEs) in allergic asthma.

Mandevilla longiflora (Desf.) Pichon improves airway inflammation in a murine model of allergic asthma.

Ethnopharmacological Relevance: Mandevilla longiflora, popularly known as "velame" in central Brazil, is a subshrub widely distributed in South America. Its xylopodium is used in the form of a decoction or infusion to treat inflammation and other ailments.

Aim Of The Study: This study aimed to evaluate the anti-inflammatory potential of M.

Evaluation of anti-inflammatory and mechanism of action of extract of Macrosiphonia longiflora (Desf.) Müll. Arg.

Ethnopharmacological Relevance: Macrosiphonia longiflora (Desf.) Müll. Arg (Apocynaceae), popularly known as 'velame' and 'velame branco', is a native subshrub that grows in the Brazilian Cerrado.

Genotoxicity of corrosion eluates obtained from orthodontic brackets in vitro.

Introduction: The purpose of this study was to evaluate whether corrosion eluates obtained from commercially available orthodontic brackets are able to induce genetic damage in vitro.

Material And Methods: Genotoxicity was assessed by the single cell gel (comet) assay using Chinese hamster ovary (CHO) cells. The following orthodontic metallic brackets were used: Morelli (Sorocaba, Brazil); Abzil (São José do Rio Preto, Brazil); Dentaurum (Pforzheim, Germany); and 3M Unitek (Puchheim, Germany).

Cytoskeleton reassembly in cardiomyocytes infected by Trypanosoma cruzi is triggered by treatment with ergosterol biosynthesis inhibitors.

We have previously shown that Trypanosoma cruzi-infected cardiomyocytes present alterations in cytoskeletal organisation in vitro. The remarkable change in the host cell cytoskeleton opened up the question of whether treatment of infected cells with antitrypanosomal compounds, such as ergosterol biosynthesis inhibitors (EBIs), allows the reconstruction of myofibrils and the microtubule network, restoring the cell biological function. Therefore, 48-h-old T.

Trypanosoma cruzi infection disrupts vinculin costameres in cardiomyocytes.

Chagas' disease cardiomyopathy is an important manifestation of Trypanosoma cruzi infection, leading to cardiac dysfunction and serious arrhythmias. We have here investigated by indirect immunofluorescence assay the distribution of vinculin, a focal adhesion protein with a major role in the transmission of contraction force, during the T. cruzi-cardiomyocyte infection in vitro and in vivo.
