Available in PDF, EPUB and Kindle. Book excerpt: The use of dental implants has been an extremely relevant tool in oral rehabilitation. However, there are systemic conditions, such as osteoporosis, that may negatively influence the osseointegration process by decreasing bone mineral density. Modifications in the microtopography and surface of the implants, as well as the use of the Leukocyte Fibrin Rich Plasma (LPRF), are strategies that have been used to increase bone healing around the implant.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Osteoporosis is associated to decrease of bone mineral density, leading to an increase of skeletal frailty and fracture risk. Surface characteristics of dental implants may influence bone response, modulating cell proliferation and differentiation. Nanostructures applied to biomaterials may contribute to a higher bone to implant contact. Previous studies have shown that Leukocyte platelet rich fibrin (L-PRF) can increase the amount and formation rate of new bone around implants.Aim: To micro-tomographically evaluate, in osteoporotic rats, the bone repair around two implant surfaces, associated of not to L-PRF, analyzing Bone to Implant Contact (IS/TS,%), Bone Volume Fraction (BV/TV,%), Bone Surface/Volume (BS/BV,%) Trabecular Thickness (Tb.Th,mm), and Total Porosity (To.Po,%).Material and methods: Mini implants with 2 types of surface (double acid etched=DAE, or with the addition of nano-hydroxyapatite = NHA; 24 implants of each type) were installed in the tibias of osteoporotic rats. In 24 rats, L-PRF was obtained with blood collection by means of cardiac puncture and posterior centrifugation, and inserted in the prepared bone site before implant insertion. The 48 rats were randomly divided into 4 experimental groups of 12 rats each: G1- DAE implants installed; G2- NHA implants installed; G3- DAE implants installed in association to L-PRF; G4- NHA implants installed in association to L-PRF. All the mini implants were prepared for the study, measured 2.7mm in length x 1.4mm in diameter, and had the same macrostructure. The animals were euthanized 7 and 30 days (7d and 30d) after implants placement (6 from each group/period). The tibias were removed for microtomographic evaluation of the bone between the threads of the implants, analyzing the previously described parameters.Results: Inter-groups differences were assessed using One-way Analysis of Variance (p

Download or read book Molecular and Cellular Advances in Endometriosis Research written by Antonio Simone Laganà and published by . This book was released on 2022 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endometriosis is defined as the presence of endometrial-like endometrial cells, glands, and stroma outside the uterus, causing a strong inflammatory-like microenvironment in the affected tissue. The exact prevalence of endometriosis is unknown, but estimates range from 2%-10% of women of reproductive age to 50% of infertile women. The etiopathogenesis of endometriosis remains controversial--immune, hormonal, genetic, and epigenetic factors may all be involved, and several theories have been proposed to explain it.This book aims to summarize some of the most recent advancements in basic and translational science (immunology, cell biology, genetics, and epigenetics) in the field of endometriosis that may create new scenarios and change our perspective of the topic.

Download or read book Handbook of Sample Preparation for Scanning Electron Microscopy and X Ray Microanalysis written by Patrick Echlin and published by Springer Science & Business Media. This book was released on 2011-04-14 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scanning electr on microscopy (SEM) and x-ray microanalysis can produce magnified images and in situ chemical information from virtually any type of specimen. The two instruments generally operate in a high vacuum and a very dry environment in order to produce the high energy beam of electrons needed for imaging and analysis. With a few notable exceptions, most specimens destined for study in the SEM are poor conductors and composed of beam sensitive light elements containing variable amounts of water. In the SEM, the imaging system depends on the specimen being sufficiently electrically conductive to ensure that the bulk of the incoming electrons go to ground. The formation of the image depends on collecting the different signals that are scattered as a consequence of the high energy beam interacting with the sample. Backscattered electrons and secondary electrons are generated within the primary beam-sample interactive volume and are the two principal signals used to form images. The backscattered electron coefficient ( ? ) increases with increasing atomic number of the specimen, whereas the secondary electron coefficient ( ? ) is relatively insensitive to atomic number. This fundamental diff- ence in the two signals can have an important effect on the way samples may need to be prepared. The analytical system depends on collecting the x-ray photons that are generated within the sample as a consequence of interaction with the same high energy beam of primary electrons used to produce images.

Download or read book Engineering of Stem Cells written by Ulrich Martin and published by Springer Science & Business Media. This book was released on 2009-10-15 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am very pleased to present this volume on engineering stem cells in Advances in Biochemical Engineering and Biotechnology. This volume stays abreast of recent developments in stem cell biology and the high expectations concerning the dev- opment of stem cell based regenerative therapies. Regenerative medicine is the focus of current biomedical research, with unique challenges related to scientific, technical and ethical issues of stem cell research, and the potential added value of connecting biomedicine with enabling techno- gies such as materials sciences, mechanical- and nano-engineering. Research activities in regenerative medicine include strategies in endogenous regeneration of injured or degenerated tissues by means of gene therapy or cell transplantation, as well as complex approaches to replace or reconstruct lost or malformed tissue structures, by applying tissue engineering approaches. In most cases, the speci- ized functional cell types of interest cannot be isolated from the diseased organ or expanded to a sufficient degree, and various stem and progenitor cell types rep- sent the only applicable cell source. In almost all cases, stem cells have to be engineered, sometimes for functional improvement, in many cases to produce large numbers of cells, and frequently to achieve efficient and specific differentiation in the cell type(s) of interest.

Download or read book Alphaherpesviruses written by Sandra Knowles Weller and published by Caister Academic Press Limited. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
