Quality of Barley From 2001 Crop - Brewery Section.

In this work, analytical parameters and sensorial properties of 11% beers brewed from 2001 crop barleys were assessed. For semipilot Czech technology beer brewing, 6 samples of barleys taken from Bohemian and Moravian regions were malted. In most cases, analytical parameters were better than the ones in 2000. The prepared malts show a low protein content, low soluble nitrogen and β-glucanes, have good values of DFLU extract difference, a low pH value of hopped wort (5,5 in average), a low content of diacetyl in beer (less than 10 mg/l) and show a relatively higher content of dimethyl sulfide precursors. Enzymatic capability of the malts was assessed as very good. When comparing with previous years, especially the clarity during run off of wort was worse. All beers showed an excellent filterability. The sensorial properties of brewed beers can be assessed as good to average. Overall, it can be said the barleys can be assessed as of highest quality in the course of the last three years. The comparison of the samples from various regions shows a better equability than in previous years.In this work, analytical parameters and sensorial properties of 11% beers brewed from 2001 crop barleys were assessed.

A prospective multicenter randomized clinical trial of autogenous bone versus beta-tricalcium phosphate graft alone for bilateral sinus elevation: histologic and histomorphometric evaluation

Purpose: Two different graft materials, beta-tricalcium phosphate (Cerasorb) and autogenous bone, were used in the same patient. The objective was to determine whether donor site morbidity could be avoided by using pure-phase beta-tricalcium phosphate (Cerasorb). Materials and Methods: Bilateral sinus grafting was performed on 20 selected patients; Cerasorb was used on the experimental side, and autogenous bone was used on the control side. In each patient, one side was randomly designated the experimental side. In 10 of the 20 patients, the maxilla reconstruction included sinus grafting and onlay bone grafting. Implants were placed 6 months after the procedure. In addition to routine panoramic radiographs, in 10 of the 20 patients, 2- and 3-dimensional computerized tomographic examinations were performed pre- and postoperatively and after implantation. Eighty bone biopsy specimens were taken at the time of implant placement. Results: Histologically and histomorphometrically, there was no significant difference between the experimental and control grafts in terms of the quantity and rate of ossification. For each histologic sample, the total surface area, the surface area that consisted of bone, and the surface area that consisted of graft material were measured in mm(2), and bone and graft material were analyzed as percentages of the total. The mean percentage bone areas were 36.47% +/- 6.9% and 38.34% +/- 7.4%, respectively, the difference was not significant (P = .25). Discussion and Conclusion: Comparisons with other studies reveal that beta-tricalcium phosphate (Cerasorb) is a satisfactory graft material, even without autogenous bone
