13. Comparing osteogenic effects between concentrated growth factors and the acellular dermal matrix
Abstract Concentrated growth factor (CGF) is an autogenuous product that contains highly concentrated number of platelets and can be derived from venous blood by selective centrifugation. It has been speculated that local growth factors in human platelets (insulinlike growth factor, IGF; transforming growth factor, TGF-b; platelet derived growth factor, PDGF

14. THE DYNAMICS OF THE SUBSTRATE RECOVERY OF WASTE DUMPS IN CALCARY MINING UNDER NATURAL REGENERATION
ABSTRACT This study aimed to evaluate the dynamics of the physical and chemical recovery of the substrates of waste dumps of different ages undergoing natural regeneration, in a calcary mining in Salto de Pirapora - SP, Brazil. Characterization of the vegetation, vegetation and physical and chemical cover of the substrates of the abandoned waste dumps since

15. Does mesenchymal stem cell improve the liver regeneration after the 70% hepatectomy?
Abstract Purpose: To evaluate the effects of mesenchymal stem cells on liver regeneration in rats following a 70% hepatectomy. Methods: Forty rats were subjected to 70% hepatectomy and then ~106 mesenchymal stem cells (test group), or saline solution (control group), were infused into their livers via the portal vein. Each treatment group was divided into

16. Effect of aqueous extract of the leaves of Baccharis trimera on the proliferation of hepatocytes after partial hepatectomy in rats
Abstract Purpose: To evaluate the effect of aqueous extract of Baccharis trimera leaves on the proliferative capacity of the liver after partial hepatectomy (PH) in rats. Methods: Twenty Wistar rats weighing between 300 and 450g were divided into two groups: control (HP) and test (HP100-rats that received the aqueous extract of Baccharis trimera for four d

17. Tissue culture efficiency of wheat species with different genomic formulas
Abstract Ancient wheats are increasingly considered as valuable resources for genes of interest which could be analyzed and introduced into cultivated varieties by genetic engineering technologies. The first stage of biotechnological crop improvement consists of successful in vitro plant regeneration. Twelve wheat germplasms with different genomic formulas (

18. Assessment of Genetic Fidelity of in vitro Raised Plants in Swertia chirayita through ISSR, RAPD analysis and Peroxidase Profiling during Organogenesis
ABSTRACT An efficient in vitro regeneration protocol for medicinally important herb Swertia chirayita was developed and the genetic fidelity was assessed using RAPD and ISSR markers. The best shoot regeneration was observed on MS basal supplemented with 1.0 mg/L Benzyl amino purine (BAP) in combination with Indole-3-acetic acid (IAA) (0.5 mg/L) that resulted

19. Litter Decomposition of Two Pioneer Tree Species and Associated Soil Fauna in Areas Reclaimed after Surface Coal Mining in Southern Brazil
ABSTRACT Decomposition of leaf litter from pioneer tree species and development of associated soil meso- and macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim of our study was to evaluate decomposition of Schinus terebinthifolius and Senna multijuga to answer three basic questions: (i) What type of leaf litter de

20. Establishment of an Embryonic Tip Regeneration System of Soybean
ABSTRACT In order to establish an optimal soybean embryonic tip regeneration system that can serve as soybean genetic transformation receptor, and be used for the study of genetic function verification, the influences of single factor on the adventitious bud of embryonic tip induction, elongation and rooting stage, are researched and compared.The single fact

21. Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in heart failure rats. MSCs were treated with different concentrat

22. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w

23. Influence of Benzyladenine and Thidiazuron on Shoot Regeneration from Leaf and Shoot tip Explants of Sedum sarmentosum Bunge
Effects of N6-benzyladenine (BA) or thidiazuron (TDZ) on adventitious shoot regeneration and axillary shoot multiplication of Sedum sarmentosum was investigated. Leaf and shoot tip explants obtained from in vitro-grown shoots of S. sarmentosum were cultured on Murashige and Skoog (MS) medium supplemented with 0, 2.0, 4.0 or 8.0 µM BA or TDZ. Of the two cyto

24. Chitosan-collagen biomembrane embedded with calcium-aluminate enhances dentinogenic potential of pulp cells
Abstract The development of biomaterials capable of driving dental pulp stem cell differentiation into odontoblast-like cells able to secrete reparative dentin is the goal of current conservative dentistry. In the present investigation, a biomembrane (BM) composed of a chitosan/collagen matrix embedded with calcium-aluminate microparticles was tested. The BM
