Full textAbstract:
The objective of this study was to evaluate the impact of female urinary incontinence (UI) on quality of life. The method of research is based on a literature search on PubMed, Cochrane library and relevant articles from 1977 to 2012. Forty-eight works were found. Literature showed that UI affects a large percentage of the aged out patients. Women experience UI because of many reasons such as childbirth, menopause and previous gynaecologic surgery. Incontinence is to be treated as it impacts physiological and psychological aspects of patient’s life. Treatments include medical, physical (rehabilitation) and surgical approaches. Measures for assessment are made up by specific and non-specific questionnaires. Evaluation of female incontinence must take into account patients with and without medical treatment. Every sort of therapy has to consider the psychological impact too. In current literature depression, anxiety, shame and decreed selfefficacy resulted as the most important factors involving women with UI.

Full textAbstract:
The article contains an exposition of the theoretical analysis of the main scientific approaches to the study of the concept of "anxiety states" and the differentiation and correlation of the concepts of anxiety, situational and personal anxiety, anxiety state. The psychological, physiological and social aspects of the emergence and manifestation of anxiety states are analyzed. Phobic to asthenic components of anxiety states are described. The reasons and consequences of anxiety in various senses of anxiety as an emotional and psychological state are considered. We see the importance of studying anxiety states in the growth trend of negative emotions in society, and in the demand for psychological support. Among modern methods of psychotherapy for anxiety states, we choose art therapy as one of the ecological means of overcoming feelings of fear, anger, shame and other negative emotional states. Particular attention is paid to the consideration of art therapy work with clay as a psychotherapeutic method of anxious personality states. A description is made and general characteristics and features of art therapy work with clay are given. Based on the study of a number of foreign studies on art therapy with clay, we saw evidence of a close correlation between the physiological and psychological aspects of human life through the experience of contact, as one of the very first basic personal experiences. When interacting with clay in the context of an art therapy process, each hand movement provides instant feedback to the brain, provides non-verbal access to psychological and sensorimotor processes. Natural clay is a natural, ecological and affordable material that provides the creation of three-dimensional objects and naturally promotes significant psychological processes through touch, revealing significant information about the inner world of the creators. Therefore, clay art therapy can be a powerful tool for solving many basic problems and stimulating an individual to social-emotional development. The relevance of the upcoming study is due to the urgent need to use psychotherapeutic methods of an innovative and systemic nature in working with anxiety states. We determine the prospect of our research in the development of a program for a therapeutic program for anxiety states using clay as a method of art therapy.

Full textAbstract:
The article presents the view on the problem of psychological maladaptation as a factor of dissatisfaction with sexual life, which is manifested in the disclosure of the data of the concepts, descriptions and characteristic features that are manifested in these concepts. The psychological aspects of the manifestation of psychological maladaptation and sexual dissatisfaction are revealed, and an empirical study of the relationship between psychological maladaptation and sexual dissatisfaction was conducted. Sexual and psychological relationships are caused by a determinant relationship (have their internal causes and external effects), this in turn indicates that sex life has an impact on interpersonal, intimate relationships among partners, and can also serve as a cause of the psychological defining of the individual. An important aspect was the sexual satisfaction with its physiological and psychological components, and the special role of various manifestations of feelings (mood, anxiety, emotions, stresses) on the sexual function of the individual was proved. The result of the study is the significance of the statistical relationship between psychological maladaptation and sexual dissatisfaction. This means that the psychological state of a person has a great influence on sexual life and vice versa, the sexual sphere of human life provides a certain amount of filling and general mental background state of personality in any life situations. With the help of theoretical and empirical analysis we received the following results: high indicators of sexual satisfaction and realized evidence of the ability of a person to feel pleasure during sexual intercourse, to control their own sexual behavior In accordance with the norms of social and personal ethics. Such a person is free of fear, a sense of shame and guilt, false representations and other psychological factors that inhibit sexual response and violate sexual relations.

Full textAbstract:
Child poverty occupies a special place in the fight against poverty of national governments and international organizations. Reducing child poverty and eradicating child extreme poverty should be a priority in the social and economic policy of any state. The aim of the study is to analyze child poverty in Russia, the United States and developing countries. Special attention is paid to the analysis of approaches to the study and tracking of child poverty by national systems and international organizations; the special significance of the negative impact of poverty in children on epigenetic, immunological, physiological, psychological types of adaptation at the age of 2-3 years was noted. This requires effective regulation to offset the negative impact of extreme poverty on children. it is substantiated that the policy of state aid to poor families with children in the Russian Federation should not be based on income poverty indicators. The influence of the depression of the Russian economy in 2014 on a sharp increase in the proportion of poor families with three or more children is shown. The special role of the experience of shame and threats to their dignity by poor children, which penetrate into all aspects of the life of poor children, negatively affects their future, is noted. The study of the role of the family, society, state, and international organizations in the elimination of child poverty in its extreme forms showed that the eradication of child poverty should be a top priority in any country.

Full textAbstract:
Deconvolution-based analysis of CT and MR brain perfusion data is widely used in clinical practice and it is still a topic of ongoing research activities. In this paper, we present a comprehensive derivation and explanation of the underlying physiological model for intravascular tracer systems. We also discuss practical details that are needed to properly implement algorithms for perfusion analysis. Our description of the practical computer implementation is focused on the most frequently employed algebraic deconvolution methods based on the singular value decomposition. In particular, we further discuss the need for regularization in order to obtain physiologically reasonable results. We include an overview of relevant preprocessing steps and provide numerous references to the literature. We cover both CT and MR brain perfusion imaging in this paper because they share many common aspects. The combination of both the theoretical as well as the practical aspects of perfusion analysis explicitly emphasizes the simplifications to the underlying physiological model that are necessary in order to apply it to measured data acquired with current CT and MR scanners.

Full textAbstract:
The response of single breast cancer cells (cell line T‐47D) to 17β‐estradiol (E2) under different concentrations was studied by using an instrument that allows to combine far‐field light microscopy with high resolution scanning near‐field (AFM/SNOM) microscopy on the same cell. Different concentrations of E2induce clearly different effects as well on cellular shape (in classical bright‐field imaging) as on surface topography (atomic force imaging) and absorbance (near‐field light transmission imaging). The differences range from a polygonal shape at zero via a roughly spherical shape at physiological up to a spindle‐like shape at un‐physiologically high concentrations. The surface topography of untreated control cells was found to be regular and smooth with small overall height modulations. At physiological E2concentrations the surfaces became increasingly jagged as detected by an increase in membrane height. After application of the un‐physiological high E2concentration the cell surface structures appeared to be smoother again with an irregular fine structure. The general behaviour of dose dependent differences was also found in the near‐field light transmission images. In order to quantify the treatment effects, line scans through the normalised topography images were drawn and a rate of co‐localisation between high topography and high transmission areas was calculated. The cell biological aspects of these observations are, so far, not studied in detail but measurements on single cells offer new perspectives to be empirically used in diagnosis and therapy control of breast cancers.

Full textAbstract:
This review discusses different aspects of the uropygial gland of birds. The gland exhibits a striking morphological diversity in size, shape and presence/absence of tufts of feathers. It was shown that acidic mucins, neutral lipids, glycolipids and phospholipids are normal components of secretion. Several morphological and physiological aspects of the gland were studied on Rock Pigeon Columba livia Gmelin, 1879. The amount of the uropygial gland secretion, its lipid content and fatty acids profile were determined. The extracted lipid mixture contained of C14 to C20 fatty acids, mostly unsaturated; the saturated fatty acids were mainly 14:0, 16:0 and 18:0. No correlation was found between the size of the gland and the aquatic/terrestrial nature of the species. Ablation of the gland did not affect survival, body weight, feeding rate and serum cholesterol, total lipids or calcium levels after 32-120 days. The possible role of the gland in the protection against lipophilic compounds was discussed. The function of the gland is still a subject of controversy. It is accepted that its secretion confers water-repellent properties on the feather coat and maintain the suppleness of the feathers. Other physiological roles of the gland secretion may be associated to pheromone production, control of plumage hygiene, thermal insulation and defence against predators. Concerning the endocrine regulation of the uropygial function, there is scarce information presenting evidence for steroid regulated mechanisms.

Full textAbstract:
AbstractFibrillar collagen is an abundant extracellular matrix (ECM) component of interstitial tissues which supports the structure of many organs, including the skin and breast. Many different physiological processes, but also pathological processes such as metastatic cancer invasion, involve interstitial cell migration. Often, cell movement takes place through small ECM gaps and pores and depends upon the ability of the cell and its stiff nucleus to deform. Such nuclear deformation during cell migration may impact nuclear integrity, such as of chromatin or the nuclear envelope, and therefore the morphometric analysis of nuclear shapes can provide valuable insight into a broad variety of biological processes. Here, we describe a protocol on how to generate a cell-collagen model in vitro and how to use confocal microscopy for the static and dynamic visualization of labeled nuclei in single migratory cells. We developed, and here provide, two scripts that (Fidler, Nat Rev Cancer 3(6):453–458, 2003) enable the semi-automated and fast quantification of static single nuclear shape descriptors, such as aspect ratio or circularity, and the nuclear irregularity index that forms a combination of four distinct shape descriptors, as well as (Frantz et al., J Cell Sci 123 (Pt 24):4195–4200, 2010) a quantification of their changes over time. Finally, we provide quantitative measurements on nuclear shapes from cells that migrated through collagen either in the presence or the absence of an inhibitor of collagen degradation, showing the distinctive power of this approach. This pipeline can also be applied to cell migration studied in different assays, ranging from 3D microfluidics to migration in the living organism.

Chapter 4 covers postreceptor intracellular messenger cascades through which neurotransmitters and neurotrophic factors, and their receptors, produce their diverse physiological effects. A major advance over the past generation of research has been an appreciation of the complex webs of intracellular signaling pathways that control every aspect of a neuron’s functioning, from neurotransmitter signaling to cell shape and motility to gene expression. While only a small number of medications used in psychiatry today have as their initial target intracellular signaling proteins, it is likely that drug development efforts will look increasingly to such proteins for the discovery of novel medications with fundamentally new mechanisms of action.

Full textAbstract:
Teeth are without doubt some of the most useful structures for zoological and archaeozoological research. Their complex crown morphology renders them extremely important in taxonomic determination, since subtle differences in shape and form can exist to species level. Of the various calcified tissues present in the mammalian body, tooth enamel is also the hardest and most stable. This is extremely important for the study of fossil remains, since teeth are very resilient to many taphonomic variables. Teeth can provide many clues about an animal’s past life. They are extremely conservative in their development and growth, which progresses in a relatively well-understood chronological sequence. As a result, crown development, and tooth eruption can provide some of the most useful archaeozoological evidence for the age at death of an individual. The mouth is also the place where the initial physical and chemical breakdown of food occurs; the teeth are the means of shearing, chopping, and mastication, and as such will be affected to varying degrees by any major changes in the physical and chemical make up of ingested food. Thus, normal progressive wear on the teeth at a macroscopic level also provides a useful and widely used methodology with which to estimate the relative age at death. Tooth development is also adversely affected by a wide range of physiological factors, which can leave a number of tell-tale ‘footprints’ in the dental tissues themselves. As a result, a permanent (and chronological) record of physiological stress can be routinely reconstructed from the study of ancient teeth. All of these approaches can be used to shed further light on aspects of animal husbandry regimes in the past. This chapter deals with the pig remains excavated at Sagalassos, a Roman to Early Byzantine town in south-western Turkey. The ruins can be found approximately 7 km north of the village of Ağlasun in the province of Burdur, and 110 km to the north of Antalya. The site lies on the southern slope of the western Taurus at an altitude of between 1450 and 1600 m a.s.l., and extends over 4km2 (Waelkens 1993).

The presented study is focused on the hemodynamics aspects of thoracic aortic aneurysm and approaches for restoring hemodynamics in the aortic arch. The study includes numerical investigation of the aortic arch hemodynamics of a healthy aorta, aorta with aneurysm, and of two endovascular repairing procedures. The first endovascular repair approach is the total aortic arch hybrid debranching. The second implantation uses chimney graft technique. The analysis includes the fluid dynamics in the aorta and branching arteries under time-dependent physiological conditions. The results show the effect of aneurysm on blood flow in the descending aorta and in aortic arch side branches. In the aneurysmatic case, the aneurysm provokes a highly disturbed flow and large recirculation regions, especially during diastole. Out of the two endovascular techniques, the hybrid procedure was found preferred from hemodynamics point of view, with less disturbed and recirculating regions. Although the chimney procedure requires less manufacturing times and cost, it is associated with higher risks rate, and therefore, it is recommended only for emergency cases. This study may shade light on the hemodynamic factors for these complications, and provide insights on ways to improve the procedure.

Full textAbstract:
Aneurysm rupture rates are often associated with factors such as size, location, and patient specific risks such as age and health. However, the actual physiological causes of the pathogenesis, enlargement, and rupture are unclear. Many studies have shown aneurysm formation to be mechanically mediated. Hemodynamic forces such as wall shear stress (WSS), pressure, and flow patterns have been examined as causes for aneurysm development and eventual rupture [1]. Geometric factors such as the aneurysm size, shape, and aspect ratio may also be important in predicting rupture [2,3].

Full textAbstract:
In a comparative ergonomic study, the ergonomic quality of 10 various screwdriver handles from European manufacturers which exhibited decisive differences in the design aspects “shape”, “dimension”, “material” and “surface” was tested. For this purpose, a test layout was developed in order to analyze the potential advantages and disadvantages of each handle type taking into account the anatomical and physiological characteristics of the human hand-arm-shoulder system. A group of 21 male right-handed test subjects (Ss) aged between 20 and 32 years, had to carry out different static and dynamic screw driving tests. In order to reveal possible model-specific differences in muscle strain, the electromyographic activity (EA) of 4 muscles involved in the different screwing tasks was measured via surface electrodes. Each of the Ss had to complete the test series with all screwdrivers under identical, controlled working conditions.Before and after the tests, the Ss had to assess specific criteria of the handles using a specially developed questionnaire addressing aspects such as handling, design features, material, surface finish as well as color design and manufacturing quality. In a second approach, the Ss were asked to express potential physical complaints in the fingers, hand, palm and forearm with respect to intensity and occurrence. This test-procedure with an objective and subjective evaluation offered a differentiated view on the impacts of the work situation and should reflect the advantages and disadvantages of the different handle types. When analyzing the results from the determined EA data and the users’ subjective perceptions while handling the screwdrivers, a great impact of the design features “shape”, “dimension”, “material” and “surface” became quite apparent. Only those screwdrivers designed according to appropriate ergonomic criteria enable a high operational performance with lower physiological costs which have to be paid by the muscles.

Abstract The temperature difference between active austenite finish temperature, Af, and the intended operating temperature in the range of 3.2 °C to 20.8 °C. has been reported to have an influence on the fatigue lifetime of a pseudoelastic shape-memory device. The negative effect on fatigue life increases with the temperature difference between active Af and, in case of a biomedical device, 37 °C body temperature. In this study, samples were prepared and processed in a manner to replicate aspects of the complex manufacturing process, device design, and geometry of state-of-the-art stents, and physiological loading conditions. Following explantation from the mock vessels after fatigue testing, the stents were inspected using optical microscopy to detect and document the location and number of strut fractures. The fatigue results were compared and assessed for statistical significance between the groups with various active Af temperatures. The variations in the heat treatments, as part of the manufacturing process, resulted in three distinct groups of samples with varying target active Af temperatures. These variances corresponded to differences in fatigue damage.
