This System Has Failed Us

When I go to a courtroom the only color I see is orange. I don’t want to talk down to people. The projection is level to the floor. There are 2,500 napkins. They are the people, the garbage, and the repetition of the excess, and my hope of giving them importance. There are roughly 2,500 people in the Orleans Parish Prison on any given day, but the system is bigger than them. It’s more consuming and this is not nearly the amount of napkins it would take to represent the people in even just one state\u27s carceral system. The space is empty. There are so many people that couldn’t be here. This isn’t about white guilt. This is a reflection of what I have seen, reformed and repurposed to be better understood. The system has failed us. But it hasn’t failed me, and I’m the system. I make art because I can’t change those truths without acknowledging them

Aufbrüche der Zivilgesellschaft: Wege, Positionen und Wirkungen der DDR-Bürgerbewegungen 1987-2014

Mit dem „Aufruf zur Einmischung in eigener Sache“ trat am 12. September 1989 „Demokratie Jetzt“ als Bürgerbewegung in der DDR in die Öffentlichkeit und erhob nachdrücklich einen politischen Mitwirkungs- und Gestaltungsanspruch in der SED-Diktatur. Genau ein Vierteljahrhundert nach der Berliner Gründungsversammlung führte die Tagung „Aufbrüche der Zivilgesellschaft“ zahlreiche der damaligen Initiatorinnen und Initiatoren, Zeitzeugen, Wissenschaftlerinnen und Wissenschaftler und interessiertes Publikum zusammen. Der runde Jahrestag war Anlass, Reverenz zu erweisen den historischen Leistungen von „Demokratie Jetzt“ und „Bündnis 90“ in der Friedlichen Revolution, im deutschen Einigungsprozess und in der Bundesrepublik. Diesen Rückblick kombinierte die Konferenz mit der Frage, welche Impulse die Bürgerbewegung der DDR und die Friedliche Revolution geben können für die Zivilgesellschaft in ihrem Verhältnis zum Staat im 21. Jahrhundert. Es ging also darum, den Aufbruch von 1989 zu aktualisieren mit Blick auf eine Gegenwart, in der die konstituierenden Faktoren dieses Verhältnisses durch dynamische Prozesse wie die Digitalisierung selbst aufgebrochen zu werden scheinen.

The Effects of Oral Consumption of Selenium Nanoparticles on Chemotactic and Respiratory Burst Activities of Neutrophils in Comparison with Sodium Selenite in Sheep

The present study was designed to compare the effects of nano-selenium and of sodium selenite on the chemotactic and respiratory burst activities of neutrophils in sheep. Fifteen sheep were randomly divided into three groups. Groups 1 and 2 received selenium nanoparticles (1 mg/kg) or sodium selenite (1 mg/kg) orally, respectively, for ten consecutive days, and the third group was considered as the control. To determine the chemotactic and respiratory burst activities of the neutrophils, the leading front assay and the NBT test were used on heparinized blood samples that were collected at different intervals (days 0, 10th, 20th, and 30th). The results obtained showed that the chemotactic activities in groups 1 and 2 increased significantly on the 10th, 20th, and 30th day, compared to day 0, and on the 20th day in comparison with the 10th day, while in group 2, there was a significant decrease on the 30th day compared to the 20th day. The chemotactic activities in group 1 were significantly higher than in group 2 on the 10th day and in the control group on the 10th, 20th, and 30th day, but the chemotactic activities in group 2 were significantly higher than those in the control group only on the 20th day. On the 30th day into the experiment, the respiratory bursts in groups 1 and 2 were significantly stronger in comparison with those at day 0. Overall, nano-selenium increased the chemotactic and respiratory burst activities more significantly than sodium selenite, which is suggestive of a stronger stimulatory effect of the Se nanoparticles on intracellular activities

Nanoparticles of Selenium as Species with Stronger Physiological Effects in Sheep in Comparison with Sodium Selenite

The present study was designed to compare the effects of nano red selenium and sodium selenite on the antioxidative activities of neutrophils and the hematological parameters in sheep. Fifteen sheep were randomly allocated into three groups. Groups 1 and 2 received selenium nanoparticles orally at 1 mg/kg and sodium selenite at 1 mg Se/kg for 10 consecutive days; group 3 served as the control. To assess the degrees of oxidative stress and of lipid peroxidation of the cellular membranes, the levels of thiobarbituric acid reactive substances (TBARS) were determined in serum samples that were collected at different supplementation intervals, i.e., after 0, 10, 20, and 30 days. In addition, hematological parameters in the serum samples were measured by routine procedures. It was found that TBARS levels in groups 1 and 2 were significantly higher on days 20 and 30 compared to the basal level on day 0. It was also found that on day 30, the TBARS activities in both treated groups were significantly higher than those of the controls (P < 0.05). These findings may explain the seemingly paradoxical effects of supplemental selenium on the indicators of oxidative stress, as the levels of TBARS were generally expected to decrease in the presence of selenium. There were no significant differences between the PCV and RBC values in the three groups. The white blood cell count (WBC) in group 1 showed a significant increase on days 20 and 30 in comparison with the control group. However, in group 2, there was a significant increase of the WBC value just on day 20 in comparison with the control group. Also, there were significant increases of the neutrophil counts and significant decreases of the lymphocyte counts on day 10 in group 1, in comparison with those in group 2 and controls, and on days 20 and 30 in groups 1 and 2 in comparison with those in the control group

A review of the renal system and diurnal variations of renal activity in livestock

Kidneys are the main organs regulating water-electrolyte homeostasis in the body. They are responsible for maintaining the total volume of water and its distribution in particular water spaces, for electrolyte composition of systemic fluids and also for maintaining acid-base balance. These functions are performed by the plasma filtration process in renal glomeruli and the processes of active absorption and secretion in renal tubules, all adjusted to an 'activity-rest' rhythm. These diurnal changes are influenced by a 24-hour cycle of activity of hormones engaged in the regulation of renal activity. Studies on spontaneous rhythms of renal activity have been carried out mainly on humans and laboratory animals, but few studies have been carried out on livestock animals. Moreover, those results cover only some aspects of renal physiology. This review gives an overview of current knowledge concerning renal function and diurnal variations of some renal activity parameters in livestock, providing greater understanding of general chronobiological processes in mammals. Detailed knowledge of these rhythms is useful for clinical, practical and pharmacological purposes, as well as studies on their physical performance

A summary of new findings on the biological effects of selenium in selected animal species: a critical review.

Selenium is an essential trace element important for many physiological processes, especially for the functions of immune and reproductive systems, metabolism of thyroid hormones, as well as antioxidant defense. Selenium deficiency is usually manifested by an increased incidence of retention of placenta, metritis, mastitis, aborts, lowering fertility and increased susceptibility to infections. In calves, lambs and kids, the selenium deficiency demonstrates by WMD (white muscle disease), in foals and donkey foals, it is associated with incidence of WMD and yellow fat disease, and in pigs it causes VESD (vitamin E/selenium deficiency) syndrome. The prevention of these health disorders can be achieved by an adequate selenium supplementation to the diet. The review summarizes the survey of knowledge on selenium, its biological significance in the organism, the impact of its deficiency in mammalian livestock (comparison of ruminants vs. non-ruminants, herbivore vs. omnivore) and possibilities of its peroral administration. The databases employed were as follows: Web of Science, PubMed, MEDLINE and Google Scholar
