Large-scale releases and establishment of wMel Wolbachia in Aedes aegypti mosquitoes throughout the Cities of Bello, Medellín and Itagüí, Colombia.

Background: The wMel strain of Wolbachia has been successfully introduced into Aedes aegypti mosquitoes and has been shown to reduce the transmission of dengue and other Aedes-borne viruses. Here we report the entomological results from phased, large-scale releases of Wolbachia infected Ae. aegypti mosquitoes throughout three contiguous cities located in the Aburrá Valley, Colombia.

Effectiveness of Wolbachia-infected mosquito deployments in reducing the incidence of dengue and other Aedes-borne diseases in Niterói, Brazil: A quasi-experimental study.

Background: The introduction of the bacterium Wolbachia (wMel strain) into Aedes aegypti mosquitoes reduces their capacity to transmit dengue and other arboviruses. Evidence of a reduction in dengue case incidence following field releases of wMel-infected Ae. aegypti has been reported previously from a cluster randomised controlled trial in Indonesia, and quasi-experimental studies in Indonesia and northern Australia.

Root defense analysis against Fusarium oxysporum reveals new regulators to confer resistance.

Fusarium oxysporum is a root-infecting fungal pathogen that causes wilt disease on a broad range of plant species, including Arabidopsis thaliana. Investigation of the defense response against this pathogen had primarily been conducted using leaf tissue and little was known about the root defense response. In this study, we profiled the expression of root genes after infection with F.

Plant growth in Arabidopsis is assisted by compost soil-derived microbial communities.

Plants in natural and agricultural environments are continuously exposed to a plethora of diverse microorganisms resulting in microbial colonization of roots and the rhizosphere. This process is believed to be accompanied by an intricate network of ongoing simultaneous interactions. In this study, we examined Arabidopsis thaliana roots and shoots in the presence or absence of whole microbial communities extracted from compost soil.

Understanding the implications of the PAX9 gene in tooth development.

Aim: Tooth agenesis is characterised by the congenital absence of one or more teeth. The Pax9 gene has been associated with nonsyndromic forms.

Materials And Methods: To investigate the molecular mechanisms, we evaluated specific haplotypes frequency in exon 3 of the Pax9 gene in 26 patients and 21 controls, using an Italian population.

Successful establishment of Wolbachia in Aedes populations to suppress dengue transmission.

Genetic manipulations of insect populations for pest control have been advocated for some time, but there are few cases where manipulated individuals have been released in the field and no cases where they have successfully invaded target populations. Population transformation using the intracellular bacterium Wolbachia is particularly attractive because this maternally-inherited agent provides a powerful mechanism to invade natural populations through cytoplasmic incompatibility. When Wolbachia are introduced into mosquitoes, they interfere with pathogen transmission and influence key life history traits such as lifespan.

Oral cavity rare lesions: 15 years case histories.

OBJECTIVES.: Oral cavity rare diseases include a various group of uncommon morbid conditions. For this reason they are often called "orphan diseases", as they are not interesting for research and the description of their natural history is not easy.

Fragile-X syndrome: genetic aspects and stomatologic evaluations.

Aim Of The Work: The fragile-X syndrome is the most common cause of inherited mental retardation and it is associated with the FMR1 gene on X chromosome. The origin of anatomic anomalies of maxillo-facial complex is still discussed in literature. The authors describe the syndrome and report a clinical case.

Five years of experience using palatal mini-implants for orthodontic anchorage.

Purpose: The authors review 5 years of clinical experience using Straumann Orthosystem (Straumann, Basel, Switzerland) palatal mini-implants for orthodontic anchorage, describe clinical procedures, and give statistical results.

Materials And Methods: Diagnostic planning, surgical phase, and clinical procedure are described. The diagnostic planning was performed on lateral cephalogram in 13 cases; in 1 case, with an ectopically included upper canine, a computed tomography was requested.

The effects of intense pulsed light (IPL) on blood vessels investigated by mathematical modeling.

Background And Objectives: Intense pulsed light (IPL) sources have been successfully used for coagulation of blood vessels in clinical practice. However, the broadband emission of IPL hampers the clinical evaluation of optimal light parameters. We describe a mathematical model in order to visualize the thermal effects of IPL on skin vessels, which was not available, so far.

Somatosensory evoked potentials of inferior alveolar nerve.

Purpose: The use of inferior alveolar nerve somatosensory evoked potentials may represent an objective means of evaluating sensory nerve function in the maxillofacial region. The aim of this work was to confirm the existence of a standard sequence of prominent events in the trigeminal somatosensory evoked potentials (TSEPs) of inferior alveolar nerve (IAN) waveform, examine those components and their normal variability by statistical analysis, and discuss TSEPs' nervous origin and some patterns of TSEPs' abnormalities due to dysfunctional nerves.

Materials And Methods: TSEPs were obtained following electrical stimulation (square wave pulses 0.

Suture in oral surgery. A comparative study.

Aim: The aim of the present paper is to continue the previous study, with 52 new additional cases, confronting in vivo the behavior of 4 different suture materials (Ethibond Excel, Monocryl, silk and Vicryl) in oral surgery.

Methods: The clinical aspects have been particularly underlined: the intraoperative easy handling, the estate of the nodes and the resistance of the thread, the plaque accumulation, the tissue response in the short term (within 3 weeks) as well as in the long term (90 days), all estimated with objective parameters.

Results: Fifty-two out of a total of 55 new subjects included in the program have been followed throughout all the experimentation.

Supernumerary teeth diagnosis and treatment approach. Six case reports.

Supernumerary teeth are relatively common in the general population, affecting the primary and the permanent dentition and have been reported in many genetic syndromes. They are classified according to form and shape. Seven different examples of hyperodontia are presented to highlight the numerical and morphological variation in dental abnormalities manifestations, empathising the importance of thorough clinical and radiological examination and of a correct therapeutic approach.

[Impacted third molars and facial typology].

Background: The increasingly frequent removal of asymptomatic or pathology free lower third molars raises several questions. In this paper, the relationships between inclusion of impacted third molars and facial typology, in studied in order to have a further evaluation parameter for their removal.

Methods: The study was carried out an 50 cephalometric radiographs.
