Abstract
BACKGROUND AND OBJECTIVE MMP-8 in gingival crevicular fluid is considered as a protease with high destructive potential because of its ability to degrade collagen in periodontitis-affected patients. The aim of this study was to investigate whether there was a relationship between clinical diagnostic parameters and the concentration of active MMP-8 (aMMP-8) in gingival crevicular fluid in a site-level full-mouth analysis. Based on these data, the prognostic value of aMMP-8 levels in relation to pocket depth may be evaluated. MATERIAL AND METHODS Clinical measurements of pocket depth, bleeding on probing (BOP), plaque index (PlI) and gingival index (GI), as well as samples of gingival crevicular fluid, were obtained from four sites of each tooth of nine healthy female patients with chronic generalized periodontitis. The aMMP-8 concentration in gingival crevicular fluid was quantified by ELISA using specific monoclonal antibodies. Multiple linear regression models for the single measures of aMMP-8 and pocket depth were calculated with GI and BOP as additional variables. RESULTS Between 92 and 112 recordings were obtained for each parameter in each patient. Mean values of between 31.5 and 88.8% were calculated for pocket depths of ≥ 4 mm. Mean pocket depths ranged from 3.11 to 4.73 mm, the mean BOP values ranged from 34.0 to 96.7% and the mean full-mouth gingival crevicular fluid aMMP-8 concentration ranged from 3.2 to 23.7 ng/mL. CONCLUSION In this sample of female periodontitis patients, a broad range of intra-individual and interindividual aMMP-8 values was found. Although the explained variance was rather weak, a statistically significant relationship between aMMP-8 and pocket depth was proven.

Abstract
Interdiffusion during growth of Fe on As-rich GaAs(001) substrates has been investigated by real time stress measurements. Compared to Ga-rich GaAs(001), interdiffusion processes are decisively reduced. The optimum growth temperature (characterized by abrupt interfaces, pseudomorphic growth and negligible intermixing) is found to lie below 50 °C. At higher growth temperatures interdiffusion effects increase and eventually lead to the formation of a compact crystalline alloy layer of presumably Fe(2 + x)Ga(1 - x), as evidenced by transmission electron microscopy and x-ray diffraction.

Abstract
INTRODUCTION More than 125 million (2 %) people worldwide wear contact lenses (CL). 0.011 - 0.2 % of the wearers develop keratitis per year. The aim of this study was to explore and analyse the spectrum of germs in different microbiological analysis techniques to optimize the strategy of antiobiotic therapy. PATIENTS AND METHODS A retrospective study about 65 eyes with CL induced keratitis or corneal ulceration who were treated in our hospital between 2005 - 2010. We analysed and compared the development of best-corrected visual acuity (BCVA) under single and combined antibiotic therapy and microbiological analysis of conjunctiva (CS) and CL and CL-container swabs (CLS). RESULTS Of the patients 96.9 % were soft contact lenses wearers. 48.8 % had microbiological findings in the CS, 81.3 % in CLS. 19.6 % (n = 9) coagulase-negative Stapyhlococcus and 17.3 (n = 8) Pseudomonas species were found. Different spectra of germs in CS and CLS were found. Gram-positive bacteria in CS (54.5 %) were dominant, whereas Gram-negative bacteria were dominant in CLS. No significant difference of mean BCVA changes between single (0.09 ± 0.2) and double (0.14 ± 0.29) topical antibiotic therapy (p = 0.16) were seen, but significant differences between the groups of "gentamicin & ofloxacin" (0.2 ± 0.2) and "moxifloxacin & tobramycin" (0.1 ± 0.43) (p < 0.05) were found. No significant differences of BCVA change between patients with positive (0.12 ± 0.23) and negative (0.20 ± 0.37) microbiological results of conjunctival swabs were observed (p = 0.5). CONCLUSIONS A strong association between keratitis among wearers of soft lenses and typical spectra of germs was found. Different microbiological findings in different swabs, a lack of findings in around 51.2 % of CS combined with the comparable clinical outcomes between sterile and "microbial" disease means the findings from CS are less important. No differences in development of BCVA between single and double antibiotical therapy were found. There was a better outcome of BCVA with ofloxacin with gentamicin compared to newer generation agents. To improve current treatment strategies in future we recommend increasing the microbiological analysis of CL and CL containers.

Abstract
BACKGROUND The National Institute of Health (NIH) published a Consensus Statement on the screening and management of Phenylketonuria (PKU) in 2000. The panel involved in the development of this consensus statement acknowledged the lack of data regarding the potential for more subtle suboptimal outcomes and the need for further research into treatment options. In subsequent years, the approval of new treatment options for PKU and outcome data for patients treated from the newborn period by dietary therapy alone have become available. We hypothesized that a review of the PKU literature since 2000 would provide further evidence related to neurocognitive, psychosocial, and physical outcomes that could serve as a basis for reassessment of the 2000 NIH Consensus Statement. METHODS A systematic review of literature residing in PubMed, Scopus and PsychInfo was performed in order to assess the outcome data over the last decade in diet-alone early-treated PKU patients to assess the need for new recommendations and validity of older recommendations in light of new evidence. RESULTS The majority of publications (140/150) that contained primary outcome data presented at least one suboptimal outcome compared to control groups or standardized norms/reference values in at least one of the following areas: neurocognitive/psychosocial (N=60; 58 reporting suboptimal outcomes); quality of life (N=6; 4 reporting suboptimal outcomes); brain pathology (N=32; 30 reporting suboptimal outcomes); growth/nutrition (N=34; 29 reporting suboptimal outcomes); bone pathology (N=9; 9 reporting suboptimal outcomes); and/or maternal PKU (N=19; 19 reporting suboptimal outcomes). CONCLUSIONS Despite the remarkable success of public health programs that have instituted newborn screening and early introduction of dietary therapy for PKU, there is a growing body of evidence that suggests that neurocognitive, psychosocial, quality of life, growth, nutrition, bone pathology and maternal PKU outcomes are suboptimal. The time may be right for revisiting the 2000 NIH Consensus Statement in order to address a number of important issues related to PKU management, including treatment advancements for metabolic control in PKU, blood Phe variability, neurocognitive and psychological assessments, routine screening measures for nutritional biomarkers, and bone pathology.
