Purchase of prescription and OTC medicines in Slovakia: factors influencing patients' expectations and satisfaction

ABSTRACT Slovakia is a country where the purchase of OTC (over the counter) medicines outside the pharmacy is not allowed by the government. This study aimed at evaluating patients' satisfaction and acceptance of community pharmacists. Customer's behaviour and expectations influencing the purchase of prescription and OTC medicines were analyzed. A structured questionnaire having 15 multiple-choice questions was used to analyze the descriptive parameters. Data collection lasted from January to February 2014. The sample size consisted of 357 high-school educated individuals under 40 years of age. The survey showed that the prescription and OTC medicines were bought equally. The participants reported a 96.0%, 96.3% and 90.2% satisfaction rate with willingness and approach of the community pharmacist, pharmacy services and provision of drug information respectively. As for the OTC medicines, 89.5% people considered the pharmacist an expert: 88.2% purchased medicines with pharmacist's recommendation, 97.8% needed a professional counselling and 97.2% required a pharmacist's guidance. As for the prescription drugs, only 72.1% considered the pharmacist an expert: 96.3% suggested that physician's prescription was significant and 88.3% considered pharmacist's guidance in the process of selection of prescription medicines nonessential. A comprehensible and respectable conversation was highly expected in regards to both the OTC and prescription medicines

Domain Analysis Reveals That a Deubiquitinating Enzyme USP13 Performs Non-Activating Catalysis for Lys63-Linked Polyubiquitin

Deubiquitination is a reverse process of cellular ubiquitination important for many biological events. Ubiquitin (Ub)-specific protease 13 (USP13) is an ortholog of USP5 implicated in catalyzing hydrolysis of various Ub chains, but its enzymatic properties and catalytic regulation remain to be explored. Here we report studies of the roles of the Ub-binding domains of USP13 in regulatory catalysis by biochemical and NMR structural approaches. Our data demonstrate that USP13, distinct from USP5, exhibits a weak deubiquitinating activity preferring to Lys63-linked polyubiquitin (K63-polyUb) in a non-activation manner. The zinc finger (ZnF) domain of USP13 shares a similar fold with that of USP5, but it cannot bind with Ub, so that USP13 has lost its ability to be activated by free Ub. Substitution of the ZnF domain with that of USP5 confers USP13 the property of catalytic activation. The tandem Ub-associated (UBA) domains of USP13 can bind with different types of diUb but preferentially with K63-linked, providing a possible explanation for the weak activity preferring to K63-polyUb. USP13 can also regulate the protein level of CD3δ in cells, probably depending on its weak deubiquitinating activity and the Ub-binding properties of the UBA domains. Thus, the non-activating catalysis of USP13 for K63-polyUb chains implies that it may function differently from USP5 in cellular deubiquitination processes

The disruption of proteostasis in neurodegenerative diseases

Cells count on surveillance systems to monitor and protect the cellular proteome which, besides being highly heterogeneous, is constantly being challenged by intrinsic and environmental factors. In this context, the proteostasis network (PN) is essential to achieve a stable and functional proteome. Disruption of the PN is associated with aging and can lead to and/or potentiate the occurrence of many neurodegenerative diseases (ND). This not only emphasizes the importance of the PN in health span and aging but also how its modulation can be a potential target for intervention and treatment of human diseases.info:eu-repo/semantics/publishedVersio

Product range models supporting design knowledge reuse

This is an article from the journal, Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture [© IMechE ]. It is also available at: http://journals.pepublishing.com/content/7l714058h9813667/Redesign, where previous information is recovered in order to be adapted to a new situation, is an area of design where information technology can potentially provide substantial benefits. Information support to product design and manufacturing has been pursued through the use of product and manufacturing models. This paper introduces a new concept of a complementary information model, called a product range model, that aims to support variant and adaptive design activities. The general concept and structure of such an information model is defined in terms of product functions and their respective design solutions. The interactions taking place between particular design solution options are discussed, and methods are proposed for their evaluation against product specifications and design constraints. The concept of knowledge links is introduced to maintain the relationships between solutions within the product range model and the particular model of the product being developed. The work has been explored using injection mould tooling as an appropriate product range and evaluated through the design and implementation of a design support system utilizing an object-oriented database
