Abstract Purpose Wire-based coronary physiology pullback performed before percutaneous coronary intervention (PCI) discriminates coronary artery disease (CAD) distribution and extent, and is able to predict functional PCI result. No research investigated if quantitative flow ratio (QFR)–based physiology assessment is able to provide similar information. Methods In 111 patients (120 vessels) treated with PCI, QFR was measured both before and after PCI. Pre-PCI QFR trace was used to discriminate functional patterns of CAD (focal, serial lesions, diffuse disease, combination). Functional CAD patterns were identified analyzing changes in the QFR virtual pullback trace (qualitative method) or after computation of the QFR virtual pullback index (QVPindex) (quantitative method). QVPindex calculation was based on the maximal QFR drop over 20 mm and the length of epicardial coronary segment with QFR most relevant drop. Then, the ability of the different functional patterns of CAD to predict post-PCI QFR value was tested. Results By qualitative method, 51 (43%), 20 (17%), 15 (12%), and 34 (28%) vessels were classified as focal, serial focal lesions, diffuse disease, and combination, respectively. QVPindex values >0.71 and ≤0.51 predicted focal and diffuse patterns, respectively. Suboptimal PCI result (post-PCI QFR value ≤0.89) was present in 22 (18%) vessels. Its occurrence differed across functional patterns of CAD (focal 8% vs. serial lesions 15% vs. diffuse disease 33% vs. combination 29%, p=0.03). Similarly, QVPindex was correlated with post-PCI QFR value (r=0.62, 95% CI 0.50–0.72). Conclusion Our results suggest that functional patterns of CAD based on pre-PCI QFR trace can predict the functional outcome after PCI.

COMBINING FUNCTIONAL AND COMPOSITIONAL ASPECTS OF THE ANALYSIS OF URBAN STRUCTURE: A CASE STUDY OF LOCAL CENTRES IN VILNIUS / FUNKCINIŲ IR KOMPOZICINIŲ URBANISTINĖS STRUKTŪROS ANALIZĖS ASPEKTŲ SUJUNGIMAS: VILNIAUS MIESTO LOKALIŲ CENTRŲ TYRIMAS

A possibility from every location in an urban grid to easily access a range of shops and local services that meet the everyday needs, as well as workplaces, educational institutions and places for recreation is one of the biggest advantages of living in a city. This paper considers that combining tasks of encouraging the growth of local centres and developing street network in a way to promote walking and to provide conditions for using different modes of transport is one of the most appropriate ways to achieve urban sustainability. The problem addressed in this paper is the “separate” (i.e. “non-combined”) approach to functional and compositional aspects of the analysis of urban structure. The main proposal presented in this paper is to combine the two methods for analysing spatial and functional patterns. The first method deals with spatial configuration and how it is used by people, the second is aimed at investigating the role of urban composition at a macro and a micro scale in ensuring coherence of the elements of urban structure. The aim of the paper is to introduce the method for analysing the spatial structure of local centres in Vilnius and present the results which were obtained using the proposed model for investigating the interdependence of functional and compositional structures of the city. The scope of the study is to reveal some inconsistencies in the spatial patterns of three local centres in the north-western part of Vilnius where the distribution of the pre-determined functions and urban composition are in non-corresponding relation. Using the spatial accessibility model of Vilnius city, the study focuses on spatial structure at the level of urban blocks, which constitute local centres. The linear elements of the model are overlaid on a ground plan where convex spaces are highlighted considering their artistic and visual potential. Choice (betweenness, a measure of centrality) as a critical measure for analysing local centres is used to identify movement related structural patterns. Santrauka Galimybė iš bet kurios miesto vietos patogiai pasiekti kasdienius gyventojų poreikius tenkinančias prekybos ir paslaugų įmones, darbo ir mokymo įstaigas bei laisvalaikio leidimo vietas yra neabejotinas gyvenimo mieste privalumas. Lokalių centrų stiprinimo ir gatvių tinklo plėtros, sudarant sąlygas susisiekti pėsčiomis bei naudotis įvairių rūšių transportu, uždavinių derinimas sprendžiant veiksmingos, efektyvios urbanistinės struktūros formavimo klausimus yra viena iš pagrindinių darnios plėtros užtikrinimo priemonių. Straipsnyje keliama funkcinių ir kompozicinių urbanistinės struktūros analizės aspektų sujungimo problema. Siekiant išplėsti urbanistinės struktūros analizės galimybes, šiame straipsnyje siūloma kartu taikyti space syntax – viešųjų erdvių tyrimo – metodiką ir urbanistinės kompozicijos vaidmens lokaliu ir globaliu lygmeniu, užtikrinant urbanistinės struktūros elementų funkcinį ir erdvinį sąryšį, nustatymo būdą. Straipsnio tikslas yra pristatyti remiantis sudarytu miesto funkcinės ir kompozicinės struktūrų sąveikos tyrimo modeliu atliktą Vilniaus miesto lokalių centrų urbanistinės struktūros tyrimą, atskleisti taikytą metodiką ir gautus rezultatus. Tyrimo metu siekta nustatyti struktūrų prieštaringumus, kurie pasireiškia suplanuotų funkcijų išsidėstymo ir urbanistinės kompozicijos neatitikimu. Nagrinėti trys lokalūs centrai, esantys Vilniaus miesto šiaurės vakarų dalyje. Naudojant Vilniaus miesto viešųjų erdvių pasiekiamumo modelį, plane išryškinti lokalius centrus sudarantys kvartalai ir jų urbanistinės erdvės struktūra – linijiniai modelio elementai ir juos dengiančios vizualiai atskiros urbanistinės erdvės dalys, kurių meninio ir vizualinio potencialo įvertinimai išreikšti sutartiniais žymenimis. Apskaičiuotos prognozuojamą žmonių srautų pasiskirstymą gatvių tinkle atspindinčios pasirinkimo arba matematinio pereinamumo vertės.

Summary: Surgical correction of dentofacial deformities may produce dramatic results. It is essential that a thorough pre-operative evaluation be performed. Therefore a close working relationship between the oral and maxillofacial surgeon and the orthodontist is essential, however consultation with other professionals is mandatory. Among these are the general dentist, family physician, psychologist, speech clinician and myofunctional therapist. An overview of orthognathic surgery has been presented in order to familiarize the myofunctional clinician with these procedures, so that functional patterns both prior to and after surgical repositioning can be properly evaluated and treated.

The results of studies general patterns formation heterogeneous structure biofilms gram-negative and gram-positive bacteria, as well as yeast-like fungi Candida spp. are presented. Рrocesses intercellular communication of various systematic groups microorganisms has common morphological and functional patterns biofilm formation. Heteromorphic structures of biofilms united by the intercellular matrix have been revealed in natural, industrial, and clinical conditions, both in the body of mammals and birds, and in food products, devices and equipment, animal husbandry and food production technologies. Indication in a large number of microcolonies, as well as yeast and micellar phases in isolates from pathological material of animals, was a differential sign in local and systemic pathologies. Under the influence drugs on biofilms microorganisms, a direct correlation was established between morphometric and densitometric indicators, reflecting a decrease in the frequency occurrence clusters and optical density, respectively. Under the bacteriostatic effect of chemotherapeutic and disinfecting drugs, accumulations altered cells of spheroplastic type, capable forming stable and unstable L-forms, were revealed. For detection of viable microorganisms in a heterogeneous population microorganisms in vitro and in vivo, fluorescence microscopy and culture media with growth factors for the repair cell wall of L-forms bacteria are promising.
