The present research aimed to study the chemical composition and acaricidal activity of Citrus limonum Piper nigrum essential oils against cattle tick Rhipicephalus microplus . GC-MS analysis C. oil showed limonene (50.3%), β -pinene (14.4%), γ -terpinene (11.7%) as major components; P. was mainly composed -caryophyllene (26.2%), σ -ocymene (5.8%), α (5.5%). Acaricide evaluated at concentrations 2.5, 5.0, 10.0% (v/v) each plant oil, well 1 : combination both (5% 5%, 2.5% 2.5%, 1.25% each),...
Background: Scedosporium apiospermum is a multidrug-resistant filamentous fungus that causes localized and disseminated diseases. Our group has previously described metalbased complexes containing copper(II) or silver(I) ions complexed with 1,10-phenanthroline-5,6- dione (phendione) inhibited the viability of S. conidial cells. Objective: The effects these promising complexes, [Cu(phendione)3](ClO4)2.4H2O (Cuphendione) [Ag(phendione)2]ClO4 (Ag-phendione), on vital biological processes,...
Acompanhar o desenvolvimento infantil é dever de todos os que são comprometidos com as infâncias. Dessa forma, necessário compreender infantil, além acesso a instrumentos eficazes acompanhamento. O vive uma suas fases mais importantes na primeira infância e por este motivo seu acompanhamento deve ser feito forma atenta cuidadosa, pela família, saúde educação. em seus domínios físico, cognitivo psicossocial, maneira apropriada, relaciona-se fundamentalmente aos cuidados humano recebe no...
This study evaluated the effect of hexamethyldisiloxane (HMDSO) plasma on fabrics surface to produce masks. Samples 400-thread count cotton fabric were used. The was covered with a layer HMDSO employing enhanced chemical vapor deposition. Optical Microscopy, helium ion beam microscopy (HIM) and atomic force (AFM) used for topographic analysis. Fourier transformed infrared spectroscopy technique analyze modifications surface. level hydrophobicity using contact angle measurements. To evaluate...
Antioxidants are currently used as efficient excipients that delay or inhibit the oxidation process of molecules. Excipients often associated with adverse reactions. Stability studies can guide search for solutions minimize processes degradation. The ability to predict reactions in different drugs is important. Methods: This study was conducted assess rational use butylated hydroxyanisole (BHA), hydroxytoluene (BHT), sodium metabisulfite (SMB), propyl gallate (PG) and cysteine (CYS) tablet...
Cutaneous leishmaniasis (CL) is a parasitic disease characterized by progressive skin sores. Currently, treatments for CL are limited to parenteral administration of the drug, which presents severe adverse effects and low cure rates. Therefore, this study aimed develop poly(vinyl-alcohol) (PVA) hydrogels containing Amphotericin B (AmB) intended topical treatment CL. Hydrogels were evaluated in vitro their potential eliminate promastigote forms Leishmania spp., prevent secondary infections,...
Aim . This study describes the biofilm formation and corrosive capacity of sulfate-reducing bacteria (SRB) on metallic structure used endodontic files. Methods Sulfate-reducing ( Desulfovibrio desulfuricans oral fairfieldensis or D. environmental) were inoculated into culture media (Postgate C medium modified Postgate E medium). The biocorrosive potential these will be an important component a biopharmaceutical under development called BACCOR. Afterwards, four files (UEFs) separately...
Leukocyte-platelet rich fibrin (PRF) is an autologous biomaterial formed by platelets, cytokines, growth factors and cells imprisoned on a mesh, produced according to Choukroun's protocol. The aim of the present article was report use PRF, associated with bone substitute, regenerative treatment large defect resulting from enucleation paradental cyst involving posterior mandible. resulted in maintenance volume, radiographic evaluation showed new formation after 40 days, suggesting osteogenic...
ABSTRACT Aim This study assessed the biocorrosive capacity of two bacteria: Desulfovibrio desulfuricans and fairfieldensis on endodontic files, as a preliminary step in development biopharmaceutical, to facilitate removal file fragments from root canals. Materials methods In first stage, corrosive potential artificial saliva medium (ASM), modified Postgate E (MPEM), 2.5 % sodium hypochlorite (NaOCl) solution white (WM), without inoculation bacteria was by immersion assays. second test...
Scedosporium apiospermum is a ubiquitous, emerging and multidrug-resistant fungal pathogen with still rather unknown virulence mechanisms.The cellular basis of the in vitro interaction between fungi host cells/tissues determinant factor for development successful vivo infection. Herein, we evaluated S. conidia lung epithelial (A549), fibroblast (MRC-5) RAW 264.7 macrophages by light scanning/transmission electron microscopy.After 4 h fungi-host cell contact, percentage infected mammalian...
Leishmaniasis is defined as a cluster of infectious diseases caused by protozoan parasites the genus Leishmania. It recognized worldwide major health problem, showing high endemicity in developing countries. The present review details this complex group neglected diseases, with important clinical spectrum and large epidemiological diversity, discusses evolution leishmaniasis treatment urgent need for less toxic, more specific effective drugs against these parasites. Finally, value natural...
This study assessed the cell viability of inoculation vehicle BACCOR (a combination sulfate-reducing bacteria plus a culture media for bacteria), biopharmaceutical product under development dental use as aid in fractured endodontic file removal from root canal. Different were evaluated: modified Postgate E (MCP-E mod), Modified without Agar-agar w/Ag), C with (MCP-C Ag) and w/Ag). Cytotoxicity was quantified by MTT test, exposing L929 Vero lines to vehicles over 24 h. The exposure line MCP-E...
The mechanism by which group B Streptococcus (GBS) interacts with human cells and disrupts physiological processes is an intriguing area of investigation continues to unfold. aim this study was investigate the adherence intracellular viability within endothelial ECV304 GBS serotypes Ia, III V isolates from patients asymptomatic carriers. (GBS-Ia 90222-urine, GBS-III 90356-liquor GBS-V 90186-blood strains) exhibited a more efficient survival mechanisms than those carriers 85147-oropharynx,...
ABSTRACT Purpose: to assess the advancement in communicative intention and cognition children with autism spectrum disorder after applying a personalized alternative communication method. Methods: patients had their (Vineland-3) assessed before intervention 10 structured sessions. The “Demystifying Alternative Communication” podcast was developed as supplementary material this study. Student’s t-test used, setting significance level at p < 0.05. Results: improved intention, higher scores...
The molecular mechanisms underlying entry of group B Streptococci (GBS) into human endothelial cells are not yet fully understood. This study is centered on the triggering signaling cascade in umbilical vein (HUVEC) during their interaction with different GBS serotypes/strains (type III: 80340-vagina and 90356-CSF type V: 88641-vagina 90186-blood). We have shown that analyzed microorganisms adhere to HUVEC, but only those strains 90356-CSF, 90186-blood presented intracellular viability....
Endothelial dysfunction is a major component of the pathophysiology septicaemic group B Streptococcus (GBS) infections. Although cytokines have been shown to activate human umbilical vein endothelial cells (HUVECs), capacity interferon (IFN)-γ enhance microbicidal activity HUVECs against GBS has not studied. We report that viability intracellular bacteria was reduced in activated by IFN-γ. Enhanced fusion lysosomes with bacteria-containing vacuoles observed acid phosphatase and...
