MMP-2, MMP-9, and iNOS Expression in Human Dental Pulp Subjected to Orthodontic Traction
2009
Abstract Objective: To test the hypothesis that some metalloproteinases (MMP-2, MMP-9) and inducible nitric oxide synthetase (iNOS) enzymes in dental pulp samples do not vary when subjected to orthodontic treatment. Materials and Methods: Human dental pulps were taken from male and female patients (N=10; age 10–14 years). A straight wire technique was used with nickel-titanium or steel archwires. The increase of pressure applied on teeth was gradual. Five patients were subjected to premolar extractions after 14 months of treatment and one after 24 months. Samples were Bouin-fixed, paraffin-embedded, and afterwards processed for immunohistochemistry using anti-MMP-2, anti-MMP-9, and anti-iNO…
Assessment of pre and postoperative anxiety in patients undergoing ambulatory oral surgery in primary care.
2017
Background To analyze the pre- and postoperative anxiety level in patients undergoing ambulatory oral surgery (AOS) in a primary healthcare center (PHC). Material and Methods Prospective and descriptive clinical study on 45 patients who underwent AOS procedures in the dental clinic of a public PHC of Spain between April and September 2015. Anxiety analysis was carried out with pre- and postoperative anxiety-state (STAI-S), anxiety-trait (STAI-T) and dental anxiety (MDAS) questionnaires. A descriptive, inferential and binary logistic regression analysis were performed for the variables age, sex, educational level, previous experience of oral treatment, type of oral surgery, degree of third m…
Is Dexamethasone superior to Ketorolac in reducing pain, swelling and trismus following mandibular third molar removal? A split mouth triple-blind ra…
2021
Background The preemptive use of anti-inflammatory drugs, such as corticosteroids and NSAIDs, has the potential to reduce pain, swelling and trismus following oral surgery. The aim of this study was to compare the efficacy of dexamethasone and ketorolac tromethamine in reducing pain, swelling and trismus after mandibular third molar removal. Material and Methods The researches implemented a triple-blind, randomized clinical trial. The study was conducted with ASA I individuals aging between 18 and 35 years, which were randomized and submitted to two interventions, one with 8mg dexamethasone and the other with 20mg ketorolac tromethamine given 1h before the procedure. The primary predictor v…
SODIUM FRACTION EXCRETION RATE IN NOCTURNAL ENURESIS CORRELATES WITH NOCTURNAL POLYURIA AND OSMOLALITY
2004
Abstract: Purpose: We verify the sodium fraction excretion rate (FE Na) and potassium fraction excretion WE K) rates in monosymptomatic nocturnal enuresis. We also correlate FE Na and FE K to urinary osmolality, nocturnal polyuria and vasopressin in the same population. Materials and Methods: A total of 438 children 6 to 15 years old (mean age 9.7) presenting with monosymptomatic nocturnal enuresis were recruited from different centers. Inclusion criteria were 3 or greater wet nights a week, no daytime incontinence and no treatment in the previous 2 months. Exclusion criteria were cardiopathy, endocrinopathy, psychiatric problems and urinary tract abnormalities. Micturition chart, diurnal (…
Effects of passiflora incarnata and midazolam for control of anxiety in patients undergoing dental extraction
2017
Background Anxiety symptoms are frequently observed in dental patients, whether they are undergoing simple or more invasive procedures such as surgery. This research aimed to compare the effects of Passiflora incarnata and midazolam for the control of anxiety in patients undergoing mandibular third molar extraction. Material and Methods Forty volunteers underwent bilateral extraction of their mandibular third molars in a randomized, controlled, double-blind, crossover clinical trial. Passiflora incarnata (260 mg) or midazolam (15 mg) were orally administered 30 minutes before surgery. The anxiety level of participants was evaluated by questionnaires and measurement of physical parameters, i…
Fos-like expression and nuclear size in osmotically stimulated supraoptic nucleus neurons
1992
This study has analysed by immunocytochemistry the pattern of expression of Fos-related proteins, as well as variations in nuclear size, after the osmotically induced activation of supraoptic nucleus neurons of the rat. In control rats most supraoptic nucleus neurons were Fos-like negative. After acute and chronic dehydration by salt-loading, the number of Fos-like positive neurons increased dramatically. The level of Fos-like immunoreactivity was higher in chronically stimulated rats, and also the neurons of the ventral region of the supraoptic nucleus were more intensely stained than those of the dorsal region. The karyometric analysis was made on electron micrographs. The mean nuclear pr…
Mass Concentration of Plasma Phospholipid Transfer Protein in Normolipidemic, Type IIa Hyperlipidemic, Type IIb Hyperlipidemic, and Non–Insulin-Depen…
1999
Abstract —Mean plasma phospholipid transfer protein (PLTP) concentrations were measured for the first time by using a competitive enzyme-linked immunosorbent assay. PLTP mass levels and phospholipid transfer activity values, which were significantly correlated among normolipidemic plasma samples ( r =0.787, P <0.0001), did not differ between normolipidemic subjects (3.95±1.04 mg/L and 575±81 nmol · mL −1 · h −1 , respectively; n=30), type IIa hyperlipidemic patients (4.06±0.84 mg/L and 571±43 nmol · mL −1 · h −1 , respectively; n=36), and type IIb hyperlipidemic patients (3.90±0.79 mg/L and 575±48 nmol · mL −1 · h −1 , respectively; n=33). No significant correlations with plasma lipid p…
Uptake and metabolism of choline by rat brain after acute choline administration.
1992
The present study is concerned with the uptake and metabolism of choline by the rat brain. Intraperitoneal administration of choline chloride (4-60 mg/kg) caused a dose-dependent elevation of the plasma choline concentration from 11.8 to up to 165.2 microM within 10 min and the reversal of the negative arteriovenous difference (AVD) of choline across the brain to positive values at plasma choline levels of greater than 23 microM. Net choline release and uptake were linearly dependent on the plasma choline level in the physiological range of 10-50 microM, whereas the CSF choline level was significantly increased only at plasma choline levels of greater than 50 microM. The bolus injection of …
Effect of Intraperitoneal Sterile Urine Injection on Abdominal Myoelectrical Activity in the Spinal Rat Model
1991
The abdominal muscle reflex contractions in response to intraperitoneal injection of homologous sterile urine and acid, alkaline, hypo- and hyperosmolar solutions are studied in an acute spinal rat model by conventional and integrated electromyographic techniques. Intraperitoneal injection of homologous sterile urine causes a powerful and almost immediate abdominal muscle contracture of relative short duration. This response seems not to be related to urine pH or osmolarity, since only when solutions with extreme variations in these parameters are injected intraperitoneally are significant abdominal muscle contractions observed.
Binaural beats or 432 Hz music? which method is more effective for reducing preoperative dental anxiety?
2020
Background The aim of this prospective clinical study was to investigate the effectiveness of binaural beats and music at a frequency of 432 Hz and compare which method is more effective for reducing preoperative dental anxiety in impacted third molar surgery. Material and Methods Ninety patients were randomly selected to the binaural beats group, music group and control group. Visual analog scale used to evaluate dental anxiety before the local anesthesia in the first measurement. Local anesthesia was applied to the all patients. Patients in the music group listened to 432 Hz tuned music using earphones for 10 minutes. Patients in the binaural beats group listened to binaural beats using e…
