Adhesion measurements in vitro
Dvořáková, Petra ; Šnejdrová, Eva (advisor) ; Mužíková, Jitka (referee)
Dvořáková Petra: Adhesion measurements in vitro. Diploma thesis. Faculty of Pharmacy in Hradec Králové, 2008. SUMMARY Introduced diploma work devotes mechanism and theory of bioadhesion, mucoadhesion and factors influencing bioadhesion in the theoretic part. Further it intents on pharmaceutical bioadhesives and introduces basic view usually used testing methods too. Experimental part this work deals with the study of adhesive and reological properties of branched terpolymers of acid D, L - lactic, glycolic and mannitol (dipentaerythritol) in concentration 3%, 5%, 8%. These oligoesters were plastified with ES in concentrations 10 - 50%. For measurement of adhesion was used material testing machine T1-FR050TH.A1K Zwick/Roell and it is at setting these experimental parameters: contact time 60s, contact force 5N and speed of detachment sample from base 300 mm/min. Rate of adhesive properties was maximal strength Fmax (strength needed for detachement sample from base). For adhesion is the most significant factor concentration of plasticizer. Increasing concentration of ES leads to declines, whereas the greatest decline was discover on increasing concentration ES from 20% to 30%. On adhesive strength has also influence molar weight of the porter, when adhesive strength increases with increasing molar weight....
Domestic violence and its prevention
Dvořáková, Petra ; Zapletal, Josef (advisor) ; Vanduchová, Marie (referee)
Domestic violence as a negative social phenomenon of our society has started to be considered as a serious topic in the Czech Republic in the last few years. It has started to be discussed in public in the 90's. Before, it was considered as a private matter not supposed to be governed by the law or any other state regulations. The aim of this thesis is to describe domestic violence in the light of criminological aspects of this topic. It is focused on concept and definitions of domestic violence, its phenomenology and etiology. Attention is paid to the victim of domestic violence, influence of domestic violence on her psyche and behavior, consequences of domestic violence and relationship between the victim and the aggressor. At least but not last there is mentioned a prevention of domestic violence and efficient help offered to victims. There are many definitions of domestic violence and we cannot say that only one is correct. Domestic violence is very comprehensive and a complicated phenomenon so it is not possible to assign only one definition as generally valid. However, it has some typical features: domestic violence differs from other violent acts in the existence of intimate relationship between aggressor and his victim, it happens in privacy and mostly without witnesses, it happens...
Chromatography method optimization for HPLC determination of carotenoids.
Dvořáková, Petra ; Šatínský, Dalibor (advisor) ; Solich, Petr (referee)
This thesis deals with searching for optimal conditions for determination of carotenoids lutein, betacarotene and zeaxanthin. High performance liquid chromatography - HPLC was used for determination. During searching for optimal conditions many various columns and mobile phases were tested. Primary information about carotenoids separation was obtained from scientific literature. There were tested both types of chromatography - normal phases chromatography and reversed phases chromatography. The most frequently tested columns were C18 columns from different producers. The biggest problem for HPLC determination and separation of these three substance were position isomers of lutein and zeaxanthin. Separation of these substances is relatively difficult and it wasn't completely solved in this thesis. In spite of it new metod for determination and separation of three carotenoids was developed. This method used isocratic elution at column Zorbax SB C18 (50 x 4,6 mm, 2 μm), UV detection at 450 nm, mobile phase of methylene chloride:hexan:acetonitrile (2,5:2,5:95), injected volume 1 μl and flow rate at 1 ml/min.
The role of fibroblast activation protein and other proteases in tumour progression
Dvořáková, Petra ; Konvalinka, Jan (advisor) ; Gemperle, Jakub (referee)
Proteases are often associated with cancer and play a role of leading enzymes responsible for tumour cell invasion and metastasis. Proteolytic activity enables proteases to influence tumour progression in many ways, including cleavage of extracellular matrix, which is necessary for invasion. This thesis deals with the study of processes by which proteases regulate tumour development, either positively or negatively, and also mentions factors influencing the activity of the proteases. In connection with invasiveness of tumour cells, a major part of the thesis is dedicated to the role of fibroblast activation protein. This serine protease is expressed in stromal fibroblasts, is able to cleave collagen and has been thus established as a therapeutic target for the treatment of carcinomas. The emphasis is also put on dipeptidyl peptidase IV, a close homologue of fibroblast activation protein, especially in relation with a selective targeting of fibroblast activation protein using the inhibitors and other therapeutic agents, whose development and use are also outlined in this thesis.
