The Media, A Polarized America & ADR Tools to Enhance Understanding of Perspectives

This article will survey: (1) the intended role of the media in a democracy; (2) the current polarized political climate in the United States; (3) the challenges facing the twenty-first century with the growth of technology, cable news, and online platforms; (4) the media\u27s role in perpetuating conflict; and (5) propose that media professionals use Alternative Dispute Resolution (ADR) tools and processes to increase the public’s understanding of differing perspectives in our conflict-laden political discourse

Acrylates in Dental Applications

In the presented chapter, the role that is played by acrylates in dentistry has been characterized. In the introduction, subject of oral diseases has been raised as well as an issue of development of dentistry over the centuries. Furthermore, characteristics of the materials that have been used over the years to receive elements used in the form of prosthetic devices or dental implants that in the most favourable way from the user’s point of view enable the restoration of the missing piece of the dentition have been performed. Next, composition, functions and types of teeth have been described. In the following sections, materials (including dentures, adhesives, impression trays and dental crowns) widely used in dentistry and dental prosthetics in the preparation of which the key role is played by acrylates have been characterized. The preparation of prostheses was described. Particular attention has been drawn on the possibility of modification of the synthesis of acrylic materials that can lead to the improvement of their properties and result in making them more favourable from the point of view of the patient. The chapter is crowned with a brief description of the studies of properties, which are subjected to dental materials before application in the dental office

ASSOCIATION BETWEEN AFFECTIVE DISORDERS AND THE USAGE OF LOW AND MEDIUM DOSES OF CORTICOSTEROIDS

It is well known that high doses of corticosteroids can induce psychiatric disorders, especially the maniacal states. However there are only a few studies that investigate the effects of low and medium doses of such drugs used for a long period of time on the patient’s mental health. The aim of the study was to investigate the prevalence and severity of affective disorders among the patients using up to 40 mg of corticosteroids (prednisone or equivalent). 54 patients during the corticosteroid therapy and 51 healthy controls were assessed with the use of the following questionnaires: Hypomania Checklist 16 (HCL-16), Beck Depression Inventory (BDI) and authors’ questionnaire. The results were analysed using SPSS Statistics version 12.5. The results indicated statistically significant differences in the prevalence of hypomania and depression between controls and study group. There were no evident correlations between either the dose or the length of the therapy and the severity of affective disorders. The study has shown that the usage of corticosteroids doses below 40 mg does have an effect on the prevalence of affective disorders. The occurrence of hypomania and depression was more common among the study group. To assess correlations further studies are needed

Barium concentration in cast roe deer antlers related to air pollution caused by burning of barium-enriched coals in southern Poland

Concentrations of Ba, Zn, Pb, Fe, and Mn were determined by atomic absorption spectroscopy in freshly cast antlers from male roe deer of different ages (2 to 4 years old and older than 4 years) collected in Balin near Chrzanów and in the vicinity of Żywiec, S Poland. Barium content ranged from 124 to 196 ppm (mean 165 ppm) in the Balin 12 samples and from 207 to 351 ppm (mean 287 ppm) in 3 antlers from Żywiec. The concentration of Ba was comparable to that of Zn (134–275 ppm, mean 169 ppm). Elevated concentrations of Ba in antlers most probably originated from direct uptake of airborne barite nanocrystals through the respiratory system and/or by digestion of barite-rich dust particles deposited on plants. Burning of Ba-enriched coals is regarded as the principal source of Ba in the investigated areas inhabited by roe deer. Increased concentrations of Ba in antlers from the Żywiec area compared to Balin reflect particularly high air pollution caused by coal-burning mostly for domestic purposes combined with an unfavorable topography that impedes efficient air circulation

Physicochemical Investigations of Hydrogels Containing Gold Nanoparticles Designed for Biomedical Use

Currently, many investigations are being performed to develop dressing materials with a positive effect on the wound healingprocess. In general, innovative dressings should ensure wound exudate absorption, constitute an external barrier limiting thepossibility of wound contamination and, importantly, also provide therapeutic properties. This work is focused on obtainingmaterials with potential use as dressings for treatment of difficult-to-heal wounds. The synthesis methodology of acrylic hydrogelsmodified with selected modifiers, i.e. arabic gum, nanogold, bee pollen and chamomile extract, was developed. Next, thesorption properties of the materials were determined as well as their behavior during the incubation in fluids imitating theenvironment of the human body. Additionally, the impact of such an incubation on their structure was evaluated by FT-IR spectroscopy.It was proved that the modifiers affected the sorption properties of hydrogels, i.e. samples with additives showed evenapprox. 2.5-fold lower swelling ability. In turn, incubation of hydrogels in simulated body fluids did not cause any rapid changesin pH, which may indicate the biocompatibility of the tested materials with the tested fluids. Thus, it may be concluded that thedeveloped materials show great application potential for biomedical purposes and may be subjected to more advanced studiessuch as cytotoxicity assessments towards selected cell lines

THE PREVALENCE OF SEASONAL AFFECTIVE DISORDER AMONG THE BLIND AND PATIENTS WITH SERIOUS VISUAL IMPAIRMENT

Background: Seasonal affective disorder (SAD) is an interesting disorder in which depression should occur at a particular time of a year, each year and it should disappear at a specific time of the year. While the prevalence of SAD among generally healthy individuals is well known, the information about the prevalence of this disorder among the blind and visually impaired patients is very limited. The aim of the study was to investigate the prevalence of SAD among the blind and people with serious visual impairment in polish population. Subjects and methods: 250 blind or seriously visually impaired individuals and 258 healthy controls were assessed with the usage of Seasonal Pattern Assessment Questionnaire (SPAQ). In research group survey was conducted with the Computer Assisted Telephone Interview (CATI) technique. In control group the questionnaire was distributed via Internet. The results were analysed with the usage statistical package - Statistica 13.1. Results: The results revealed that among people suffering from SAD there is statistically significant difference in SPAQ scores between completely blind and seriously visually impaired people. The study shows that is the control group age is negatively correlated with score in SPAQ score, while in the study group age is positively correlated with SPAQ score. The data show that there is a difference in occurrence of SAD between men and women. Conclusion: The study has shown a significant difference in occurrence of SAD between study and control groups. What is more the analysis has indicated major difference in the occurrence of SAD between men and women from the study group. Taking into consideration the fact that this is the second analysis of this type in Europe further investigations are needed

ASSOCIATION BETWEEN DEPRESSION AND HEMODIALYSIS IN PATIENTS WITH CHRONIC KIDNEY DISEASE

Depression is the most common and serious psychiatric disorder that affects patients with chronic kidney disease and end-stage renal disease, and, has a significant impact on their quality of life. The aim of this study was to investigate and compare prevalence rates of depression among hemodialyzed patients, and non-dialyzed patients with a glomerular filtration rate <30 ml/min/1.73m2 receiving conservative treatment or following kidney transplantation. A total of 50 hemodialyzed and 50 non-dialyzed patients with stage 4/5 of CKD was assessed using the following questionnaires: Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), The Satisfaction with Life Scale (SWLS), The Acceptance of Illness Scale (AIS), and The Life Orientation Test-Revised (LOT-R). The use of steroids and immunosuppressant drugs was also investigated. Symptoms of depression and anxiety were present in both groups, however the proportion of persons with mild or severe depression was higher among dialyzed patients. The AIS, LOT-R and SWLS scores were very similar in both the groups. The patients using steroids and/or immunosuppressant drugs were more prone to develop mild or severe depression according to the HAM-D scores. The results indicated a high prevalence of depression and anxiety among patients with CKD. Furthermore, the fraction of patients with depression is greater among hemodialyzed patients. This indicates the importance of monitoring the mental state of the patients as well as the necessity of providing timely psychological care for patients with CKD
