Correlations between incisor and condylar movements during lateral excursion in children with primary dentition

The purpose of this study was to look for associations between lower incisor movement and working and balancing condylar movement during lateral excursion in children with primary dentition and adults with permanent dentition. Mandibular movement was recorded using a TRI-MET (an optoelectronic analysis system with six degrees-of-freedom) at a sampling frequency of 100 Hz. The movement data was transferred to a graphics workstation for analysis. Subjects were categorized by age into two groups. The primary dentition group consisted of 19 children (mean age: 5 years and 5 months, s.d.: 8.7 months), and the permanent dentition group consisted of 22 women (mean age: 20 years and 5 months, s.d.: 26.3 months). The occlusion and TMJ in both groups were normal, with no history of orthodontic treatment. Three orthogonal excursive ranges and the 3D linear distance of the incisal and balancing and working condylar points, along with inter- and intra-individual correlations between the incisor and the balancing and working condyles during lateral excursion, were estimated by using multilevel statistical models. Lateral excursion in children with primary dentition was characterized by smaller incisor excursive ranges and 3D linear distance than in adults, and stronger inter- and intra-individual correlations between incisor and balancing condylar movements than in adults. In both children and adults the lateral excursion of the incisor was a good indicator of the extent of balancing condylar movement, but not working condylar movement.

Copper and Nickel Microsensors Produced by Selective Laser Reductive Sintering for Non-Enzymatic Glucose Detection

In this work, the method of selective laser reductive sintering was used to fabricate the sensor-active copper and nickel microstructures on the surface of glass-ceramics suitable for non-enzymatic detection of glucose. The calculated sensitivities for these microsensors are 1110 and 2080 μA mM⁻¹·cm⁻² for copper and nickel, respectively. Linear regime of enzymeless glucose sensing is provided between 0.003 and 3 mM for copper and between 0.01 and 3 mM for nickel. Limits of glucose detection for these manufactured micropatterns are equal to 0.91 and 2.1 µM for copper and nickel, respectively. In addition, the fabricated materials demonstrate rather good selectivity, long-term stability and reproducibility.     

A case of planned pregnancy with an interruption in infliximab administration in a 27-year-old female patient with rheumatoid-factor-positive polyarthritis juvenile idiopathic arthritis which improved after restarting infliximab and methotrexate

We report a 27-year-old case of juvenile idiopathic arthritis (JIA) having been stopped infliximab during pregnancy. She was safely treated by infliximab therapy with premedications for preventing infusin reactions after her delivery, and then improved in the same manner as when she had been treated with infliximab therapy before pregnancy. As a result, it remains unclear whether or not we can use infliximab to control disease activities during pregnancy. In addition, it is also important to clarify whether or not premedications should be used when resuming infliximab treatment in such patients after pregnancy. These problems still remain controversial. More definitive data are needed in order to allow rheumatologists to better select the optimal TNF-alpha inhibitor therapy when treating pregnant JIA patients.     

Direct ESR Measurement of Free Radicals in Mouse Pancreatic Lesions

In this experiment, free radicals in the pancreas of endotoxemia and ethionine induced acute pancreatitis in mice were attempted to be detected directly by ESR spectroscopy, using 77 freeze-trapping and 25 °C DMPO spin trapping techniques. In the 77 K freeze-trapping method, Mn (II) ion and R-00’ radical were detected in endotoxemia and ethionine induced pancreatic lesions. The heme-NO radical was observed at 6 and 24 h after isolation of the normal pancreas, and signal intensity was increased with time. This finding supports that ESR spectroscopy is a useful method for detecting the tissue degeneration process from ischemia to necrosis. Using the DMPO spin trapping technique (25 °C), 6-line was detected at 6 h after intraperitoneal administration ofE. coli in the model of endotoxemia, and 3- and 6-lines and a signal suggestive of DMPO-OH adduct were noted at 12 and 24 h in ethionine pancreatitis. These findings suggest that impaired, pancreatic tissues exist in a considerably oxidative environment and oxygen derived free radicals may be considered to play an important role in the development of pancreatic lesions.
