(Elsevier, 2003)Helicobacter pylori ATCC43504 responds chemotactically to aspartic acid and serine, but not to arginine, nor to sodium bicarbonate. In contrast, H. pylori ATCC700392 (strain 26695) shows chemotaxis to all four attractants. ...
-
(2005)Background: The aim of this work was to improve the assessment of the periodontal disease status through measurements of extracellular matrix metalloproteinases (MMPs) and their tissular inhibitors (TIMPs) in the ...
-
(1992)Ni2+, Fe2+ and Cu2+ were attractants and aspartate was an apparent repellent for Leptospirillum ferrooxidans, a behaviour opposite to that for Escherichia coli. Membranes from L. ferrooxidans contained proteins with a ...
-
(2004)Background: Genetic polymorphisms for interleukin (IL)- 1α and - 1β have been proposed as potential genetic markers for periodontal diseases. Since the prevalence of these polymorphisms could be race-related, and no data ...
-
(American Academy of Periodontology, 2000)Background: The prevailing concept is that little or no clear benefit is derived from antibiotic therapy in chronic periodontitis. Studies to determine the effect of metronidazole plus amoxicillin (M+A) on adult periodontitis ...
-
(2005)Background: Several studies have investigated genetic polymorphisms for cytokines as potential genetic markers for periodontitis. Some studies have found that interleukin (IL)-1A and IL-1B polymorphisms are associated with ...
-
(2005)Background: One hypothesis to explain the association between periodontal disease (PD) preterm/low birth weight (PT/LBW) is that PT/LBW may be indirectly mediated through translocation of bacteria or bacterial products ...
-
(Elsevier Masson SAS, 2006)Introduction. Craniofacial growth in cleft lip and palate patientsis controversial. Structural alterations of the face in these patientscould be due to the surgical treatment combined with the primaryvariations of the ...
-
(BC Decker Inc., 2000)Objective: This study was conducted to compare craniofacial relationships, position, and curvature of the cervical spine between children with cleft lip and cleft palate who had been operated on and children without ...
-
(Churchill Livingstone, 2002)INTRODUCTION Osteochondral rib grafts are most commonly used for mandibular condylar replacements. However, when used in growing patients, unpredictable growth of the constructed condyle/ramus is a common complication. ...
-
(2001)This study examines a new surface treatment that uses coarse calcium phosphate, which provides the benefits of surface roughening without introducing any foreign materials that may become imbedded in the implants. It is ...
-
(John Wiley and Sons Ltd, 2000)We human beings live in the explanations of our existence as living beings. These explanations of our existence include what we call the 'laws of nature'. Though we name them laws, we cannot claim that they have an existence ...
-
(2002)Background: Recent studies have suggested that periodontal disease is a risk factor for preterm low birth weight (PLBW). A randomized controlled trial was undertaken to help further evaluate the proposed association ...
-
(1999)Objective: To determine the fraction of an ingested fluoride dose of 1 mg in 50 mL orange juice that is excreted through the urine (FUEF) of children aged 3-5 years. Methods: Eighty-eight controlled determinations involving ...
-
(1998)Due to limitations in the availability of autogeneic bone and to the inefficiency of the fresh allogencic bone grafts, it has been necessary to evaluate the use of allogeneic processed bone. Therefore, the ability of three ...
-
(John Wiley and Sons Inc., 2016)Polyethylene micro-sized wear particles released from orthopaedic implants promote inflammation and osteolysis; however, less is known about the bioactivity of polyethylene nano-sized wear particles released from the last ...
-
(Blackwell Munksgaard, 1998)The purpose of this case-control study was to determine the association between very-mild-to-moderate enamel fluorosis and exposure during early childhood to fluoridated water, mainly through ingestion of powdered milk. ...
-
(Blackwell Munksgaard, 1998)The purpose of this comparative study of caries and dental fluorosis experience in Chilean children was to estimate the optimal range of fluoride concentration in tap water under conditions currently prevailing in Chile. ...
-
(1992)The basal lamina anionic sites of the epithelial attachment apparatus (EAA) were investigated at the electron microscopic level in adult rat periodontium. After 1M NaCl junctional epithelium detachment, an irregular and ...
-
(1991)Integrated electromyographic activity of masseter and anterior temporal muscles was recorded using bipolar surface electrodes in 33 young adults. Subjects were skeletally classified according to ANB angle reading corrected ...
