Failure of ProTaper rotary Ni-Ti instruments used by undergraduate students
2012
Objective: To evaluate the effect of number of uses, angle and radius of curvature and type of instrument on the fracture of ProTaper rotary instruments when used by undergraduate students. Study Design: Three hundred and seventy-six molars, with a total of 1114 root canals, extracted were instrumented by undergraduate students using ProTaper instruments according to the manufacturer´s recommendations. When fracture occurred, data were collected concerning the number of uses, type of instrument, level of fracture, angle and radius of curvature. ANOVA test were used to determine the influence of type of instrument in the incidence of instrument fracture. Logistic regression model was used to…
Surgical time for graft preparation using different suture techniques
2016
Background: The purpose of the present study was to compare the operative time for graft prepa- ration using different techniques for graft sutur- ing. Material and methods: Flexor profundus tendons were harvested from fresh pig hind-leg trotters. Three different suture techniques were investigat- ed: the Krackow stitch (K), the Whipstitch (W), and the Modified Finger-Trap suture (MFT). Ten- dons were sutured starting at 10 mm from the dis- tal free end of the tendon. The suture configura- tions of the Krackow stitch and Whipstitch were completed with five suture throws. According to the MFT technique, the suture was wrapped five times around the tendon over a distance of 30 mm. The time re…
A rare case of peri-implant distal radius fracture☆
2021
A peri-implant fracture near the volar plate of distal radius represent a very rare injury. The main factor of this lesion is high energy trauma on the wrist. We report a case of a 61-year-old woman with a peri-implant fracture located just proximally to the plate and a fracture of the ulnar head that occurred after a simple fall. The patient was surgically treated by plate and screws removal. The fracture was fixed using a longer volar plate for the radial fracture and a plate for the head ulnar fracture. Different factors such as osteoporosis, BMI and screw position could influence the fracture pattern. However, considering growing use of plates for distal radius fracture fixation, the fr…
Nutraceutical Value of Pantelleria Capers (Capparis spinosa L.)
2019
Abstract: Unopened flower buds of Capparis spinosa L. (capers), generally used in the Mediterranean area as food flavoring, are known to be a good source of bioactive compounds. The aim of this work was to evaluate the nutraceutical value of salt-fermented capers collected from different areas of Pantelleria Island (Italy), testing their methylglyoxal and glyoxal trapping capacity and antioxidant activity by 2,2-diphenyl-1-picryl hydrazyl (DPPH), [2,2-azinobis(3-ethylben- zothiazoline-6-sulfonic acid)] diammonium salt (ABTS), and oxygen radical absorbance capacity (ORAC) assays. Hydrophilic extracts were also characterized by high-performance liquid chromatography–electrospray ionization/ma…
Estroprogestins and cardiovascular risk in Polycystic Ovary Syndrome
2013
Because PCOS women present an increased cardiovascular risk, the safety of estroprogestin treatment is debated and contrasting data have been reported. However, cardiovascular risk is not the same in all PCOS women and individual cardiovascular risk should be assessed before staring any estroprogestin treatment. The available data show that products containing both second generation and third generation progestins (including drosperinone and cyproterone acetate) represent a safe treatment in PCOS patients with regular cardiovascular risk. In PCOS patients with increased cardiovascular risk, a careful choice of estroprogestin product is needed and cardiovascular risk should be monitored duri…
An international perspective on hospitalized patients with viral community-acquired pneumonia
2019
Background Who should be tested for viruses in patients with community acquired pneumonia (CAP), prevalence and risk factors for viral CAP are still debated. We evaluated the frequency of viral testing, virus prevalence, risk factors and treatment coverage with oseltamivir in patients admitted for CAP. Methods Secondary analysis of GLIMP, an international, multicenter, point-prevalence study of hospitalized adults with CAP. Testing frequency, prevalence of viral CAP and treatment with oseltamivir were assessed among patients who underwent a viral swab. Univariate and multivariate analysis was used to evaluate risk factors. Results 553 (14.9%) patients with CAP underwent nasal swab. Viral CA…
PPAR-γ Agonist GW1929 But Not Antagonist GW9662 Reduces TBBPA-Induced Neurotoxicity in Primary Neocortical Cells
2013
Tetrabromobisphenol A (2,2-bis(4-hydroxy-3,5-dibromophenyl)propane; TBBPA) is a widely used brominated flame retardant. TBBPA induces neuronal damage, but the mechanism by which this occurs is largely unknown. We studied the possible involvement of peroxisome proliferator-activated receptor gamma (PPAR-γ) in TBBPA-induced apoptosis and toxicity in mouse primary neuronal cell cultures. TBBPA enhanced both, caspase-3 activity and lactate dehydrogenase (LDH) release in neocortical cells after 6 and 24 h of exposition. These data were supported at the cellular level with Hoechst 33342 staining. Immunoblot analyses showed that, compared with control cells, 10 μM TBBPA decreased the expression of…

La teneur en lipides du régime affecte les capacitésd'absorption intestinale et la triglycéridémie postprandiale: contribution du récepteur nucléaire…

The dietary long chain fatty acid have crucial functions into the organism such as energysource, eicosanoïdes synthesis, gene regulation). The fat disposal is essential and depend onintestinal barrier. It is well known that intestinal fat absorption is efficient. However, we don'tif the high triglycerides bioavailability of gut is attributable to inborn properties or to acquiredproperties. To answer this question, mice were subjected to a high-fat diet (40%, w/w) during21 days. We have shown that high-fat induces : 1) intestinal LCFA uptake, 2) intestinalmitotic index which leads to an increase of intestinal relative mass, 3) expression of genesinvolved in fatty uptake (Fatty Acid Transport…
