Clinical course of patients with episodic cluster headache treated with corticosteroids inproximity to the sphenopalatine ganglion: A preliminary stu…
2011
Objective: A study is made of the clinical course of patients with episodic cluster headache following the injection of corticosteroids in the proximity of the sphenopalatine ganglion of the affected side. Study Design: A retrospective observation study was made corresponding to the period between 2006 and 2010. Patients with episodic cluster headache received corticosteroid infiltrations in the vicinity of the sphenopalatine ganglion. Data were collected to assess the clinical course, quantifying pain intensity and quality of life. A total of 23 patients (11 women and 12 men) with a mean age of 50.4 years (range 25-65) were included. Forty percent of the patients had undergone dental extra…
Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish Population
2011
Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayıs University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontog…
Demographic profile of oral nonodontogenic cysts in a Brazilian population
2013
Objectives: The purpose of this study was to determine the clinical and demographic characteristics of oral non- odontogenic cysts (ONOC) in a Brazilian population over a 53-year period and to compare this data with the literature. Study D esign: A total of 20.391 biopsies records were evaluated, from April/1959 to August/2012. Cases of oral developmental cysts were selected. Data regarding age, gender, time of evolution, and anatomic site of all cases were collected. The data were analyzed by descriptive statistics. Results: Among 20.391 oral biopsies, 71 (0.35%) met the criteria of ONOC. Females accounted for 50.70% of all cases. The mean age observed was 38.14 years (range: 5-88 years). …
Outcomes of uvulopalatopharyngoplasty with harmonic scalpel after failure of continuous positive airway pressure in sleep apnea syndrome.
2012
Our data highlight that uvulopalatopharyngoplasty (UPPP) with harmonic scalpel (HS) is a reliable treatment in selected patients affected by obstructive sleep apnea (OSA) and users of continuous positive airway pressure (CPAP).The aim of this paper was to verify the efficacy and applicability of UPPP with HS in the treatment of patients affected by OSA and users of CPAP.A total of 21 patients with a retropalatal obstruction and users of CPAP underwent UPPP with HS and were evaluated (before and 6 months after surgery) using the apnea/hypopnea index (AHI); oxygen desaturation index ≥4% (ODI(4)); Epworth Sleepiness Scale (ESS); snoring level (SL); subjective assessment of the postoperative pa…
Breathe Right Nasal Strips and the Respiratory Disturbance Index in Sleep Related Breathing Disorders
1999
This investigation assesses the effects of Breathe Right nasal strips on the respiratory disturbance index (RDI) measured by polysomnography in patients suffering from obstructive sleep apnea and snoring. The positive effect of these strips on nasal ventilation was shown in earlier studies. Twenty-six patients with an RDI higher than 10 in an initial measurement underwent a second preoperative polysomnography with Breathe Right nasal strips in place. Nineteen of these 26 patients showed reduction of RDI during the second night of polysomnography using the nasal strips, indicating that nasal obstruction seems to be a predominant factor in the etiology of snoring and apnea in these individua…
Search for neutral MSSM Higgs bosons at LEP
2006
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of Higgs bosons. The search results are used to set upper bounds on the cross-sections of various Higgs-like event topologies. The results are interpreted within the MSSM in a number of "benchmark" models, including CP-conserving and CP-violating scenarios. Thes…
Effect of the addition of different doping agents on visible light activity of porous TiO2 photocatalysts
2018
Abstract The influence of the addition of different doping agents (N, W and Hf) on the macroporous TiO2 photoactivity toward the Rhodamine B degradation and ethanol photo-oxidation was evaluated. The samples were characterized by XRD, XPS, SEM, TEM, N2 adsorption-desorption, UV–vis Diffuse Reflectance and Photoluminescence spectroscopies to study also the changes in the physico-chemical properties due to the presence of dopants. The photonic effect and the high ordered porous structure of the macroporous TiO2 that lead to increase the path length of the light, were the key factors that allow to enhance the catalytic activity towards the dye and VOC degradation under visible and solar light …
Evolution of the Amygdala in Vertebrates
2007
The main aim of this article is to identify the homologues of the different components of the mammalian amygdala in the cerebral hemispheres of non-mammals using, primarily, a topological/embryological perspective. Thus, we first consider two main divisions of the amygdala of mammals, namely the pallial and subpallial (striatopallidal) amygdala. The pallial amygdala includes derivatives of both the lateral and ventral embryonic pallium that in the adult conform layered, superficial areas usually called cortical amygdala, and deep nuclei that conform the basolateral division of the amygdala plus the amygdalohippocampal area (AHA). The components of the subpallial amygdala are usually grouped…

Involvement of the Pseudomonas aeruginosa MexAB–OprM efflux pump in the secretion of the metallophore pseudopaline
2020
ABSTRACTThe ability for all organisms to acquire metals from their environment is essential for life. To overcome the metal restriction imposed by the host’s nutritional immunity, bacterial pathogens exploits the use of small high metal affinity molecules called metallophores. Metallophores are first synthetized in the cytoplasm, then secreted into the medium where they sequester the metal. The metal-metallophore complex is then imported into the bacterium following binding to dedicated cell surface receptors. Recently, a new family of metallophores has been discovered in pathogenic bacteria called staphylopine in Staphylococcus aureus and pseudopaline in Pseudomonas aeruginosa. Here, we ar…
