Triggers and markers of skin aging in women with menopausal syndrome

Introduction. External manifestations of aging, and especially skin aging are the most important for modern women.Aim. The aim of our study was to identify a set of adverse factors that effect on the skin of women in menopausal transition (MP) and in postmenopause (PM), and to identify markers of skin aging in this category of women.Materials and methods. The study included 36 women in MP and PM suffering from MS. At the first stage, anamnesis was collected, anthropometric data and severity of MS were evaluated, and the hormonal profile of patients was determined. At the second stage, computer mapping of the skin was performed using the digital video camera Aramo SG with the skin XPpro program. Statistic analysis was performed using the SPSS v13.0 program. Spearman’s analysis was used to determine the relationship between anthropometric, clinical and anamnestic data and the measurements of skin condition of women in MP and PM. Results. According to the obtained data, the main triggers of skin aging of women in MP and PM are: the presence of metabolic disorders (obesity, metabolic syndrome), decrease of estradiol and progesterone levels in blood serum as well as increase of prolactin level and rhythm disturbance of melatonin secretion. Markers of skin aging in women with menopausal syndrome are decreased moisture, increased oiliness in T-zone, increased of skin pigmentation and enlarged pore size.Conclusions. The obtained data are useful for management involuting skin changes of women in PM and MP suffering from MS. The data justifies the relevancy to normalization not only the estradiol level, but other sex steroids, melatonin, as well as correction of metabolic endocrine processes, and treatment of MS.

The Relationship

Background: Acanthosis nigricans (AN) is a skin condition that presents clinically with hyperpigmented, hyperkeratotic, and velvety skin changes, especially in the intertriginous areas. The intertriginous areas are also susceptible to superficial cutaneous fungal infections. The potential relationship between AN and cutaneous fungal infection has not been investigated. Objective: The aim of this study was to determine the relationship, if any, between AN and fungal infection, both clinically and pathologically. Methods: A retrospective review was performed using electronic medical records and histology of biopsy slides obtained from 29 patients who were diagnosed with AN by two dermatopathologists. Comparison was made between the clinical and pathological findings of AN with fungal infection (ANFI+) and AN without fungal infection (ANFI-). Results: Among the 29 patients with AN, fungal spores were detected on the biopsy slides of 18 patients (62.1%) and appeared in the epidermal furrow more often than in the epidermal ridge. No significant clinical difference was found between the ANFI+ and ANFI- groups; however, in the ANFI+ group, lesions were more prevalent in the neck area (p = 0.048). In addition, the ANFI+ biopsy slides revealed more papillomatosis than ANFI- biopsy slides (p = 0.006). Conclusion: Fungal infection tends to appear in combination with AN when more severe papillomatosis is also present.

Background: Nicotine has a negative infuence on the human body, but its efect is particularly noticeable on the skin. It might quicken the natural skin aging process, cause unfavorable skin changes or intensify the course of many skin or mucosa diseases including cancer. It might also inhibit wound healing processes. Furthermore, tobacco smoke damages DNA as it is the source of free radicals. Nicotine increases the degradation of collagen and elastic fbres forming the basic skin structure and causes angiogenesis, too. These processes result in forming wrinkles and losing skin frmness as well as elasticity.Aim of the study: The study aims at assessing the infuence of active tobacco smoke on skin condition factors like hydration, lubrication, faking and the infammation of epidermis in a group of young women. Material and methods: The study was carried out in a group of young women (20 with tobacco dependence and 20 never smoking) aged 21-26. An interview was performed before the study. The study of greasiness, exfoliation and skin hydration was done using the device named Nati Analizer Beauty of Science. The skin of the subjects was not washed before the test and any skin caring preparations had not been applied since the day before. For a period of fve weeks the subjects underwent the treatments with the use of sonophoresis along with the introduction of a moisturizing and sebum regulating ampoule, in order to verify the efectiveness of cosmetic treatment. After a series of treatments the test was performed again with the use of the same device. Before the study, the researchers hypothesized that active nicotine smokers will have a worse skin condition than non-smokers.Results: The interview performed did show that smokers are aware of negative efects of nicotine on their skin, so they pay more attention to daily care, and use cosmetics with a strong moisturizing action. Active nicotine smokers did not have a worse skin condition than non-smokers. Conclusions: The results received have not confrmed the hypothesis and popular beliefs that skin condition of active smokers is worse than this of none-smokers. The sonophoresis treatment had a greater impact on reducing sebum secretion in non-smokers, but they increased the degree of moisture in non-smokers.Keywords: active smoking, passive smoking, skin hydration, skin lubrication

The Relationship

This book offers a study of the subject matter protected by each of the main intellectual property (IP) regimes. With a focus on European and UK law particularly, it considers the meaning of the terms used to denote the objects to which IP rights attach, such as ‘invention’, ‘authorial work’, ‘trade mark’, and ‘design’, with reference to the practice of legal officials and the nature of those objects specifically. To that end it proceeds in three stages. At the first stage, in Chapter 2, the nature, aims, and values of IP rights and systems are considered. As historically and currently conceived, IP rights are limited (and generally transferable) exclusionary rights that attach to certain intellectual creations, broadly conceived, and that serve a range of instrumentalist and deontological ends. At the second stage, in Chapter 3, a theoretical framework for thinking about IP subject matter is proposed with the assistance of certain devices from philosophy. That framework supports a paradigmatic conception of the objects protected by IP rights as artifact types distinguished by their properties and categorized accordingly. From this framework, four questions are derived concerning: the nature of the (categories of) subject matter denoted by the terms ‘invention’, ‘authorial work’, ‘trade mark’, ‘design’ etc, including their essential properties; the means by which each subject matter is individuated within the relevant IP regime; the relationship between each subject matter and its concrete instances; and the manner in which the existence of a subject matter and its concrete instances is known. That leaves the book’s final stage, in Chapters 3 to 7. Here legal officials’ use of the terms above, and understanding of the objects that they denote, are studied, and the results presented as answers to the four questions identified previously.

SummaryFeline cutaneous paraneoplastic syndrome is a rare disorder associated mainly with pancreatic carcinoma and thymoma. In this report the authors describe the case of a 12-year-old cat with paraneoplastic exfoliative dermatitis associated with thymoma. Lateral radiographic examination of the chest showed a small subtle soft tissue density in the ventral part of the first and second intercostal space, which together with skin changes suggested thymoma. Because of pain associated with the skin condition, costs of treatment and the risk associated with surgical treatment, the owner chose euthanasia of the cat. Post-mortem examination revealed a tumour which was diagnosed as thymoma by histopathological examination.

The Relationship

The self-loosening process of a bolted joint consists of two distinct stages. The early stage of self-loosening is due to the cyclic plastic deformation of the materials. The second stage of self-loosening is characterized by the backing off of the nut. The current work is concentrated on an experimental investigation of the second stage self-loosening. Over one hundred bolted joints with M12×1.75 bolts and nuts were experimentally tested using a specially designed testing apparatus. The experiments mimicked two plates jointed by a bolt and a nut and were subjected to cyclic transverse shear loading. During an experiment, the relative displacement between the two clamped plates, denoted by δ, was a controlling parameter. For a given preload, the relationship between, Δδ/2, the amplitude of the relative displacement between the two clamped plates, and, NL, the number of loading cycles to loosening followed a pattern similar to a fatigue curve. There existed an endurance limit below which self-loosening would not persist. A larger preload resulted in a larger endurance limit. However, a large preload increased the possibility for the bolt to fail in fatigue. The results suggest that the use of a regular nut is superior to the use of a flange nut in terms of self-loosening resistance.

This research proposed a methodology for specifying the location of an object with image processing. The objectives of this methodology are to capture the target area, and specify the location of the object by using image. In order to locate the dropping object on the image plane efficiently, consecutive images are analyzed and a threshold operation is proposed. Because the accuracy of the dropping objects location on the difference of consecutive images image plane is usually influenced by noise. Moreover, transformation unit is adopted to map the XY coordinate on image plane into the world coordinate for an accuracy of the dropping objects position. After we get the actual XY coordinate of the dropping object, we can find the distance from the target point (center) and clock direction of the dropping object related to the center also. In addition, by using one digital video camera set on the tower and pan to capture the image on the target area to detect the dropping object from the air to the ground. It made the proposed methodology provide easier portability to detect the dropping object in any area.
