Antiviral Potential of (L.) Hitchc. Plant Extracts Against and Viruses.

Chikungunya and Mayaro fevers are viral infectious diseases characterized by fever and arthralgia, for which there are currently no effective vaccines or treatments. The urgent need for novel antiviral agents against Chikungunya virus (CHIKV) and Mayaro virus (MAYV) has led to interest in plant-based compounds that can disrupt the viral replication cycle. (L.

Methanolic Extracts of in Biorational Management: Larvicidal and Repellent Potential, and Selectivity against Non-Target Organisms.

The use of formulations containing botanical products for controlling insects that vector human and animal diseases has increased in recent years. Plant extracts seem to offer fewer risks to the environment and to human health without reducing the application strategy's efficacy when compared to synthetic and conventional insecticides and repellents. Here, we evaluated the potential of extracts obtained from caninana, (L.

Chemical composition, antioxidant activity and development of a facial serum formulation from the extract of .

The goal of this work was to chemically characterise extracts to develop an antioxidant serum formulation. Stem and bark extracts were prepared using 70% hydroethanol solution by Sohxlet and ultrasound assisted extraction. The content of total phenols, flavonoids, and antioxidant activity were evaluated, and chemical characterization was performed by HPLC -detector UV-VIS (SPD - 10 A).

Obtaining Hexoses from Chitosan through Depolymerization with Nitrous Acid.

Background And Objective: Residues from shrimp farming have a great potential for sugar production and the production of derivatives for the low-carbon chemical industry. Obtainment of bioactives from chitosan has been extensively investigated using different methodologies. The purpose of this work was to study the chitosan depolymerization reaction aiming at the production of monomers without the use of additional enzymes or mineral acids.

The effects of Rosmarinus officinalis L. essential oil and its nanoemulsion on dyslipidemic Wistar rats.

Dyslipidemias are lipid metabolism alterations that cause increased levels of serum lipoprotein, cholesterol, and triglycerides. These alterations are associated with a higher incidence of cardiovascular diseases and are a risk factor for atherosclerosis development. This study aimed to evaluate the effect of Rosmarinus officinalis essential oil (EORO, 100 mg/kg) and its nanoemulsion (NEORO, 500 µg/kg) on Triton and coconut saturated-fat-induced (CSF) dyslipidemias using Wistar rats.

Vascular Closure Devices Attenuate Femoral Access Complications of Primary Percutaneous Coronary Intervention.

Objectives: To compare severe complications related to radial access and those related to femoral access using vascular closure devices for patients undergoing primary percutaneous coronary intervention (PCI).

Background: Femoral artery access is still used for acute myocardial infarction management; studies comparing state-of-the-art radial and femoral techniques are required to minimize bias regarding the outcomes associated with operator preferences.

Methods: We performed a randomized study comparing radial access with a compression device and anatomic landmark-guided femoral access with a hemostatic vascular closure device.

Cochlospermum regium (Mart. ex Schrank) Pilg.: Evaluation of chemical profile, gastroprotective activity and mechanism of action of hydroethanolic extract of its xylopodium in acute and chronic experimental models.

Ethnopharmacological Relevance: Cochlospermum regium (Bixaceae) is a native shrub of Brazil and its xylopodium (infusion/decoction) is being used for the treatment of gastritis, ulcers, arthritis, intestinal infections, gynaecological infections, skin diseases, among others. The aim of the present study was to evaluate the gastroprotective/antiulcer activity and the mechanism of action of hydroethanolic extract of C. regium xylopodium (HECr), using in vitro and in vivo models.

Ocimum gratissimum L. leaf flavonoid-rich fraction suppress LPS-induced inflammatory response in RAW 264.7 macrophages and peritonitis in mice.

Ethnopharmacological Relevance: Ocimum gratissimum L. is a herbaceous plant that has been reported in several ethnopharmacological surveys as a plant readily accessible to the communities and widely used for the treatment of inflammatory diseases. The main goal of this study was to investigate the in vitro and in vivo anti-inflammatory activity and mechanism of action of the ethylacetate fraction of O.

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.

Comparison of a vascular closure device versus the radial approach to reduce access site complications in non-ST-segment elevation acute coronary syndrome patients: The angio-seal versus the radial approach in acute coronary syndrome trial.

Objectives: To compare the radial versus femoral approach using Angio-Seal for the incidence of access site complications among non-ST-segment elevation acute coronary syndrome patients undergoing invasive strategy.

Background: Arterial access is a major site of complications after invasive coronary procedures. Vascular closure devices provide more comfort to patients decreasing time to hemostasis and need for bed rest.

Femoral versus radial access in primary angioplasty. Analysis of the ACCEPT registry.

Background: The radial access provides a lower risk of bleeding and vascular complications related to the puncture site in comparison to the femoral access. Recent studies have suggested a reduction in mortality associated with the radial access in patients with acute myocardial infarction undergoing percutaneous coronary intervention.

Objective: To compare the occurrence of adverse cardiovascular ischemic and hemorrhagic events in patients undergoing primary angioplasty according to the type of arterial access route.

Design and rationale of the AngioSeal versus the Radial approach In acute coronary SyndromE (ARISE) trial: a randomized comparison of a vascular closure device versus the radial approach to prevent vascular access site complications in non-ST-segment elevation acute coronary syndrome patients.

Background: Arterial access is a major site of bleeding complications after invasive coronary procedures. Among strategies to decrease vascular complications, the radial approach is an established one. Vascular closure devices provide more comfort to patients and decrease hemostasis and need for bed rest.
