Among these, the degree of varus was the only significant factor on the multivariable regression analysis (p = 0.005).

The mean VCA in our population was 6.03°; however, the wide distribution of the VCA in our patients does not support the use of a fixed value. The severity of the pre-operative varus seems to be an independent factor with a positive correlation to the VCA and may also provide a clue to the ideal VCA if measurement of this angle is not available.

To evaluate the effects of mixed chlorhexidine (CHX)/hydrogen peroxide (H

O

) mouthrinses compared with CHX mouthrinse alone on plaque, tooth stain, and gingivitis.

This study was a double-blind, randomized two group parallel experiment, using a 14-day non-brushing half-mouth model. learn more The test group was randomly assigned to the mixed 0.12% CHX and 1.5% H

O

mouthrinse, whereas the control group used 0.12% CHX. Sixty healthy volunteers were enrolled in the study and received scaling and polishing 2weeks prior to the experiment and then rinsed with the allocated mouthrinses twice daily for 2weeks. The plaque, stain, and gingivitis scores were evaluated and recorded by a calibrated investigator.

Fifty-two subjects completed the study (CHX + H

O

n = 25/CHX n = 27). There were significant differences between the control and test groups for plaque index (CHX 0.64 ± 0.41 vs. CHX + H

O

0.46 ± 0.36, p = 0.035) and stain intensity at proximal areas (CHX 0.26 ± 0.36 vs. CHX + H

O

0.09 ± 0.14, p = 0.019) at the end of the experimental non-brushing side. However, the gingival indices did not differ significantly (CHX 0.61 ± 0.34 vs. CHX + H

O

0.62 ± 0.31, p = 0.938) between groups.

In the absence of oral hygiene practice, the mixed CHX + H

O

mouthrinse was slightly superior in reducing plaque scores and stain compared with CHX alone.

The clinical effectiveness of CHX + H

O

is comparable with CHX mouthwash alone. Therefore, the use of the mixed mouthrinse is beneficial compared with CHX for minimizing biofilm and tooth staining.

Immunocytochemical and molecular analyses reveal that the disassembly of the cell wall may be mediated by changes in the level and subcellular location of extensin protein and hemicelluloses during olive-fruit abscission. Although cell-wall modification is believed to underlie the changes in organ abscission, information concerning the changes in cell-wall proteins and hemicellulose polysaccharides is still limited. The aim of this work was to analyze the spatio-temporal patterns of the distribution of different extensin proteins and hemicelluloses in the abscission zone (AZ) during natural ripe-fruit abscission in olive (Olea europaea L.). In this study, we employed immunogold labeling in the ripe-fruit AZ during olive AZ cell separation, using an expanded set of monoclonal antibodies that recognize different types of hemicelluloses (LM11, LM15, and LM21), callose (anti-(1,3)-β-D-glucan) and extensin (JIM19) epitopes, and transmission electron microscopy imaging. Our data demonstrate that AZ cell separatioion of the LM15 xyloglucan epitopes in AZ cell walls, whereas AZ cells were found to be enriched with respect to the xylan and callose levels of the cell wall during olive ripe-fruit abscission. By contrast, AZ cell-wall polysaccharide remodeling did not involve mannans. Moreover, in ripe-fruit AZ, quantitative RT-PCR analysis revealed that OeEXT1, OeEXT2, OeXTH9, and OeXTH13 genes were downregulated during abscission, whereas the expression of OeXTH1, OeXTH5, and OeXTH14 genes increased during abscission. Taken together, the results indicate that AZ cell-wall dynamics during olive ripe-fruit abscission involves extensin protein and hemicellulose modifications, as well as related expressed genes. This is the first study available demonstrating temporal degradation of extensin protein and hemicelluloses in the AZ at the subcellular level.

This study was carried out to evaluate the utility of susceptibility-weighted imaging (SWI) in demonstrating retinal hemorrhages (RH) in pediatric head trauma.

Over a period of 7 years 67children (age 0-4years) with head trauma and MRI were included as either abusive head trauma (AHT) (n = 23), non-abusive head trauma (NAHT) (n = 38), or indeterminate (n = 6). Two pediatric neuroradiologists jointly reviewed the MR images for the presence of RH and sensitivity and specificity of SWI and T2WI were calculated.

The dilated fundoscopic examination (DFE) was positive for RH in 18/23 (78.3%) of the AHT group, 5/38 (13.2%) in the NAHT group, and 4/6 (66.7%) in the indeterminate group. Regarding the SWI MRI findings, SWI was positive for RH in 13/23 (%56.5), while T2WI was positive in 6/23 (%26.1) of the AHT group. Based on utilizing DFE as astandard, the sensitivity and specificity of SWI in the detection of RH was 63% and 100%, respectively and 30% and 100%, respectively on T2WI.

Our results suggest that SWI is auseful diagnostic tool for detection of RH in pediatric head trauma in whom DFE is difficult to perform.

However, these entities share many epidemiologic, radiologic, and pathologic features. While recent surgical and pathological literature has supported classifying MEST and ACN within the same tumor family, most radiologists and radiology texts continue to describe MEST and ACN as separate entities.
