1. The Relationship Between Serum Concentration of Interleukin-35 and FoxP3 Polymorphism in Patients Undergoing Coronary Artery Bypass Graft Surgery
Abstract Objective: To investigate the association between interleukin-35 (IL-35) levels and single nucleotide polymorphisms (rs3761548, rs3761547) of the FoxP3 gene in coronary artery bypass grafting (CABG) patients. Methods: We conducted a prospective study including 140 patients, who were scheduled for elective isolated on-pump CABG with cardiopulmonary

2. Grafting polypropylene over hollow glass microspheres by reactive extrusion
Abstract Hollow glass microspheres HGM are light, round, hollow, hydrophilic microspheres used to produce polyolefin composites with reduced density. To maintain mechanical strength, it is necessary to improve the adhesion between the polymer matrix and the microspheres, which is done by a compatibilizer. For polypropylene composites a maleic anhydride graft

3. Reaction of wild Solanaceae rootstocks to the parasitism of (Meloidogyne javanica)
RESUMO A produção intensiva de hortaliças em ambiente protegido pode aumentar a quantidade de inóculo de patógenos habitantes do solo, a exemplo dos nematoides das galhas. Dessa forma, objetivou-se avaliar o potencial de solanáceas como porta-enxertos resistentes ao nematoide Meloidogyne javanica como alternativa à enxertia em tomateiro. O experimento

4. Differential expression of the genes involved in responses to water-deficit stress in peach trees cv. Chimarrita grafted onto two different rootstocks
ABSTRACT Water deficit is responsible for a negative impact on agricultural systems. Several physiological, biochemical, and molecular processes are initiated as a response to water-deficit stress. Quantifying the differential expression of the genes involved in the response to water-deficit stress plays a key role in the development of molecular strategies

5. Ultrasound-assisted synthesis of polyacrylamide-grafted sodium alginate and its application in dye removal
Abstract A polymeric adsorbent based on sodium alginate (SAG) grafted with polyacrylamide (PAM) (SAG- g-PAM) was synthesized using an ultrasound-assisted method. The addition polymerization was carried out with ammonium persulfate as the initiator, at different acrylamide (AM) concentrations. The SAG-g-PAM copolymers were evaluated by FTIR and 13C NMR spect

6. Non-invasive messenger RNA transcriptional evaluation in human kidney allograft dysfunction
The aim of the present study was to evaluate messenger RNA expression in kidney allograft recipients. Forty-four kidney transplant recipients were evaluated up to three months after grafting. After transplantation, peripheral blood samples were drawn sequentially for real-time polymerase chain reaction analyses of perforin and TIM-3 genes. Biopsies were obta

8. Preparation and Structural Characterization of Hydroxylethyl Methacrylate Grafted Natural Rubber Latex
The graft copolymer with semi-interpenetrating polymer networks (semi-IPNs) from 2-hydroxyethyl methacrylate (HEMA) and natural rubber (NR) latex was prepared using cumene hydroperoxide and tetraethylene pentamine redox initiator system. The changes of grafting ratios and grafting efficiency with the reaction time and temperature, the concentration of crossl

9. Synthesis and properties of collagen-g-poly(sodium acrylate-co-2-hydroxyethylacrylate) superabsorbent hydrogels
Novel biopolymer-based superabsorbent hydrogels were prepared by grafting crosslinked poly(acrylic acid-co-2-hydroxyethyl acrylate) (PAA-co-PHEA) chains onto collagen backbones through a free radical polymerization method. The graft copolymerization reaction was carried out in a homogeneous medium and in the presence of ammonium persulfate (APS) as initiator

10. Comparison of Citrus tristeza virus (CTV) isolates by RFLP analysis of the coat protein nucleotide sequences and by the severity of the symptoms
Plants of Pera sweet orange on Rangpur lime rootstocks, from orchards of the northwest and north of Paraná state, Brazil, were evaluated for severity of symptoms and genetic diversity of Citrus tristeza virus. The severity of symptoms was evaluated by the development of tree, fruit size and stem pitting symptoms. Isolates that infect these plants were compa

11. Avaliação clínica, histológica e imunológica de enxertos ósseos alógenos fresco-congelados utilizados como técnica na preservação de rebordo alveolar pós-extração / Preservation of alveolar bone in extraction sockets using fresh-frozen bone allograft: a clinical, histological and immunological study
The fresh-frozen bone allograft (FFBA) is an alternative to surgical procedures of bone grafts, mainly in the preservation of alveolar ridge prior the installation of osseointegrated implants. However there are paradigms that surround the relation between immune response to alloantigens present inside the graft and the clinical response of the graft. An atte

12. Efeito de métodos de propagação no desenvolvimento de doenças e na produtividade de um clone de maracujazeiro-azedo.
RESUMO: As doenças causadas por patógenos do solo provocam perdas expressivas em maracujazeiros comerciais. A utilização de porta-enxertos resistentes pode ser uma das alternativas para o controle dessas doenças. A Passiflora nitida é uma das espécies de Passifloraceae que apresentam resistência a essas doenças, mas suas sementes geram porta-exertos
