To evaluate the outcomes with and without aid of a computer-assisted surgical navigation system (CASNS) for treatment of unilateral orbital wall fracture (OWF).

Patients who came to our hospital for repairing unilateral traumatic OWF from 2014 to 2017 were included in this study. The patients were divided into the navigation group who accepted orbital wall reconstruction aided by CASNS and the conventional group. We evaluated the surgical precision in the navigation group by analyzing the difference between actual postoperative computed tomography data and preoperative virtual surgical plan through color order ratios. We also compared the duration of surgery, enophthalmos correction, restoration of orbital volumes, and improvement of clinical symptoms in both groups systemically. Quantitative data were presented as mean ± SD. Significance was determined by the two-sample t-test using SPSS Version 19.0 A p<0.05 was considered statistically significant.

Seventy patients with unilateral OWF were include with the conventional treatment for OWF, the use of CASNS can provide a significantly better surgical precision, greater improvements in orbital-cavity volume and eyeball projection, and better clinical results, without increasing the duration of surgery.The aim of this study was to develop and to validate a UPLC-MS/MS method for the quantification of morphine, morphine-3-glucuronide, and morphine-6-glucuronide in mouse plasma and tissue homogenates to support preclinical pharmacokinetic studies. The sample preparation consisted of protein precipitation with cold (2-8 °C) methanolacetonitrile (11, v/v), evaporation of the supernatant to dryness, and reconstitution of the dry-extracts in 4 mM ammonium formate pH 3.5. Separation was achieved on a Waters UPLC HSS T3 column (150 × 2.1 mm, 1.8 µm) maintained at 50 °C and using gradient elution with a total runtime of 6.7 min. Mobile phase A consisted of 4 mM ammonium formate pH 3.5 and mobile phase B of 0.1% formic acid in methanolacetonitrile (11, v/v). Detection was carried out by tandem mass spectrometry with electrospray ionization in the positive ion mode. The method was validated within a linear range of 1-2,000 ng/mL, 10-20,000 ng/mL, and 0.5-200 ng/mL for morphine, morphine-3-glucuronide, and morphine-6-glucuronide, respectively. In human plasma, the intra- and inter-run precision of all analytes, including the lower limit of quantification levels, were ≤ 15.8%, and the accuracies were between 88.1 and 111.9%. It has been shown that calibration standards prepared in control human plasma can be used for the quantification of the analytes in mouse plasma and tissue homogenates. The applicability of the method was successfully demonstrated in a preclinical pharmacokinetic study in mice.Urinary catecholamines and their methylated metabolites are biochemical indicators of pheochromocytoma, paraganglioma and neuroblastoma. A rapid and precise analytical method based on solid-phase extraction (SPE) and liquid chromatography separation coupled to high-resolution mass spectrometry (LC-HRMS) was developed and validated to measure urinary catecholamines (epinephrine (E), norepinephrine (NorE), dopamine (D)) and total methylated metabolites (normetanephrine (NorMN), metanephrine(MN) and 3-methoxytyramine (3-MT)) in a clinical setting. Results of 51 urine specimens measured using this LC-HRMS method were compared with a liquid chromatography assay with electrochemical detection (LC-EC). Urine samples (200 μL) were spiked with an internal standard solution followed by SPE purification. In the case of total methylated metabolites, urine was hydrolyzed before SPE purification. Separation was achieved on an Acclaim Mixed Mode WCX column, with an 8.5 min runtime. All compounds were detected in electrosprahput.
The purpose of this in vitro study was to determine and compare the shear bond strength and ARI score of one traditional etch-and-rinse adhesive system serving as control, with those of two other all-in-one adhesives but with enamel acid etching preceding their application, and of one new 8th generation all-in-one bonding agent combined with a traditional adhesive used to bond stainless steel buccal tubes to molar teeth.

Four groups of teeth were formulated according to the adhesive system used to bond the tubes on the molars. Shear bond strength was measured using a universal testing machine (Hounsfield, UK). buy PIK-75 After debonding, each enamel surface was imaged using Inspex HD l080p Vesa camera (Ash Technologies Ltd., Ireland) to determine the ARI score.

The mean SBSs in MPa for the four groups were respectively A 9.640 (±3.69), B 10.261 (±3.03), C 9.689 (±2.48), D 8.412 (±3.02). No statistically significant differences were neither found through one-way ANOVA to exist between the group means (P 0.715), nor for the ARI score frequence through Chi
(P 0.534). Maxcem Elite showed four and G-Premio Bond zero instances of enamel fracture.

1.SBSs of all adhesives and ARI score distributions did not present any significant differences when used to bond stainless steel molar tubes. 2.All adhesives presented with acceptable shear bond strengths for clinical use. 3.Maxcem Elite under the tested conditions presented the greatest and G-Premio the least number of enamel fractures.

One of the most commonly used materials is polylactic acid (PLA) - a material, which is non-toxic, biodegradable and biocompatible. Fused filament fabrication (FFF) is a preferable additive manufacturing technique to manufacture polymers, where PLA is one of the most common materials. FFF is a promising technique for customised biomedical applications due to its relatively low cost and geometrical flexibility where biomedical applications are patient tailored. This study is the first to consider FFF monolayered thin films of PLA in terms of mechanical and hydrolytic properties at 37 °C in vitro degradation. Throughout degradation, the reduction in mechanical properties was examined by analysing molecular weight and thermal properties. FFF monolayered PLA underwent autocatalytic bulk degradation with no proof of significant mass loss. Young's modulus, ultimate tensile strength and molecular weight reduced by approximately 60%, 86%, and 80% after 280 days, respectively, while the degree of crystallinity increased by 143% in comparison to benchmark thin films at day 0.
