Abstract

The theory of aesthetic education treats art as an educational space. It is interesting to look at theories of the end of art from a pedagogical perspective. The article presents a few selected items, symptoms of the collapse of art, which have appeared in theories of a crisis of art. Are they relevant to the theory of aesthetic education? Is education “for” and “through” art justified in the face of the end of art? In this article the author presents catastrophic visions of art from the pedagogical perspective.

Abstract

Since the foramina provide important reference points to radiologists and surgeons, and because their shape and size may affect the blood supply to the cerebellum and the brainstem, the knowledge of the variation of foramina transversaria is essential from the medical point of view. The variation in the number, size and shape of foramina transversaria was studied based on 129 skeletons (68 male, 61 female, total of 1065 foramina) from the environs of Sypniewo. In both sexes single foramina were the most frequent (ca. 70%); in females no double foramina were observed, while triple foramina appeared only twice. In males double foramina formed ca. 40% and triple foramina were very rare. The shape and size of foramina depended to the same extent on the position of the vertebra and on the body side.

Abstract

Oral contraceptive agents are currently the most popular and one of the most effective methods for preventing pregnancy. The data shows that over 300 million women in the world use contraceptive drugs containing synthetic hormones to avoid an unwanted pregnancy. Their effects may affect other systems, leading to the occurrence of various problems associated with the use of the drug. The aim of the study is to estimate the frequency of prevalence of subjective effects associated with the use of combined hormonal contraception with a predominance of gestagens by young women Surveys were conducted among female students of Wrocław universities from December 2010 to January 2011. They covered 257 women aged statistically 23.58 (SD=2.95). They were divided into three age classes: 19-22, 23-24, 25-28. The individual age of menarche and the hormonal type of body were determined. Only persons with a gestagenic or estrogenic type of body were qualified for the study. Results: 64.6% of all respondents declared the use of hormonal contraception. Combined agents with a predominance of gestagens constituted 87% in this group. Their use brings both positive (90%) and negative (65%) aspects. The most common positive effects include high contraceptive effectiveness, regulation of menstruation and minimisation of skin problems. The most frequent negative effects include: weight gain, spotting, breast swelling and decreased libido. Surprisingly, the study did not show any correlation between the hormonal type and the occurrence of side effects. There was no significant statistical relationship between the type of hormonal contraception used and the hormonal type.

Abstract

In the study two human skulls recovered from archaeological excavations at St. Elizabeth’s Church in Wrocław, dating from the 13-14th centuries were assessed. Direct measurements of each skull were recorded, and X-ray images in P-A, lateral and basal projections were taken. The skulls represented adult males. Large, bony, lobular tumours were found on the palatine bones of both skulls. X-ray examination identified these tumours as osteoid osteomas, which are benign bone tumours that may originate in the periosteum or may be located inside the bone, distorting the maxilla or mandible. However, osteoid osteoma of the palatine is very rare. This study extends our knowledge regarding the health and diseases of historical populations.

Abstract

Hepatic stellate cells (HSC) are a nonparenchymal population of liver cells. In normal conditions, they store vitamin A, control the turnover of the extracellular matrix, and regulate the contractility of the sinusoids. Acute and chronic damage such as that brought about by alcohol activates the stellate cells and they are then responsible for the liver's inflammatory fibrotic response. Hence, alcohol consumption leads to hepatitis, steatosis, fibrosis and cirrhosis of liver by way of different mechanisms depending on effect upon the nonparenchymal cells of the liver.

The aim of our study was to assess the histological changes in the liver of rats after chronic alcohol consumption. In our work, we evaluated the intensity of liver fibrosis and the number of Kupffer cells and active hepatic stellate cells present within a test population. In the experiment, we used 10 Wistar rats of 250 gram weight. The animals were placed within one of two groups: A (experimental) and C (control). Group A received alcohol for 4 weeks, while group C received just water. The rats of both groups were decapitated 24 hours after the end of the experiment. The samples of liver were then evaluated after H&E, Masson’s trichrome staining and an immunohistochemical reaction to desmin (a marker of quiescent HSC) and α-smooth muscle actin (marker of active HSC) antibody. In our work, we observed intensive fibrosis in the portal spaces and perivenular areas in group A samples. Moreover, Kupffer cells and stellate cells with positive α-SMA expression were more numerous in group A than in the group C, and these correlate with the area of intensive fibrosis. The expression of desmin in the HSC was seen in both groups to a similar level.

Conclusion: Chronic alcohol consumption activates the transdifferentiation of hepatic stellate cells into the positive α-SMA myofibroblast-like cells which are responsible for fibrogenesis.
