The effects of temperature and calcium on pectin methylesterase (PME) activity and texture in tomato pericarp material were examined. Heating thin slices of pericarp to temperatures between 50 °C and 75 °C led to the rapid evolution of methanol from the material, indicating an activation of PME. This activity was further stimulated when CaCl2 (up to 2.0% w/v) was added. When applied to half-inc...

The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

The electrical impedance of kiwifruit [Actinidia deliciosa (A. Chev) C.F. Liang et A.R. Ferguson, cv. Hayward] was studied during fruit ripening. Measurements were made on whole fruit, and tissues excised from the outer pericarp, inner pericarp and core. Alternating current at frequencies between 50 Hz and 1 MHz was passed through fruit and tissue samples, and complex impedance spectra were sep...

Fruit firmness and crispness are important traits of cucumber because they directly affect its commercial value. We performed quantitative trait locus (QTL) analysis these fruit texture with the double-digest restriction-site-associated DNA sequencing (ddRAD-Seq) technique detected 31 QTLs for firmness: 11 placenta firmness, 12 skin 8 flesh firmness; 25 crispness-related scores: 10 index, appar...

BACKGROUND Rotational thromboelastometry is increasingly used to detect hyperfibrinolysis, which is a predictor of unfavorable outcome in patients with coagulation disturbances. In an in vitro study, the authors investigated which thromboelastometric hemostatic parameters could be valuable for fast diagnosis of the severity of hyperfibrinolysis and confirmed their findings in a patient populati...

The paper presents different objective instrumental methods for studying the rheological behaviour of either fresh or thermally treated potato tissue at large and small deformations. It describes the methodology followed and the equipment used to perform fundamental objective assays of compression, tension, shear, stress-relaxation and creep compliance, and imitative direct texture profile anal...

The influence of CaCl2 and borax on growth, yield, and quality of tomato was investigated during the years 2009 and 2010. The experiment was laid out with a randomized complete block design. Calcium chloride (0.3% and 0.6%) and borax (0.2% and 0.4%) solutions were applied as foliar sprays either alone or in combination and data were recorded for plant height, branches per plant, flowers per clu...

INTRODUCTION During liver transplantation, continuous laboratory monitoring of complex changes of the hemostatic system is necessary. The aim of this study was to compare two methods of monitoring: standard coagulation tests and rotational thromboelastometry. MATERIAL AND METHODS The study included 17 patients who had undergone orthotopic liver transplantation in the Clinical Centre of Vojvod...
