Giant mitochondria of various shapes and with different internal structures and matrix density have been observed in a great number of tissues including nerves. In most instances, the presence of giant mitochondria has been associated with a known disease or with abnormal physiological conditions such as anoxia or exposure to cytotoxic compounds. In these cases degenerative changes occurred in other cell organelles and, therefore the giant mitochondria also were believed to be induced structural abnormalities.Schwann cells ensheating unmyelinated axons of bovine splenic nerve regularly contain giant mitochondria in addition to the conventional smaller type (Fig. 1). These nerves come from healthy inspected animals presumed not to have been exposed to noxious agents. As there are no drastic changes in the small mitochondria and because other cell components also appear reasonably well preserved, it is believed that the giant mitochondria are normally present jin vivo and have not formed as a post-mortem artifact.

Needle Liver Biopsy

A white boy six months of age was hospitalized with respiratory distress and congestive heart failure. Control of the heart failure was achieved but marked cardiomegaly, moderate hepatomegaly, and minimal muscular weakness persisted.At birth a chest x-ray had been taken because of rapid breathing and jaundice and showed the heart to be of normal size. Clinical studies included: EKG which showed biventricular hypertrophy, needle liver biopsy which showed toxic hepatitis, and cardiac catheterization which showed no obstruction to left ventricular outflow. Liver and muscle biopsies revealed no biochemical or histological evidence of type II glycogexiosis (Pompe's disease). At thoracotomy, 14 milligrams of left ventricular muscle were removed. Total phosphorylase activity in the biopsy specimen was normal by biochemical analysis as was the degree of phosphorylase activation. By light microscopy, vacuoles and fine granules were seen in practically all myocardial fibers. The fibers were not hypertrophic. The endocardium was not thickened excluding endocardial fibroelastosis. Based on these findings, the diagnosis of idiopathic non-obstructive cardiomyopathy was made.

The Way

This is a reflection on the power of endings and time boundaries, exploring the way that time can act as a catalyst in psychotherapeutic processes. The article describes the ending processes with five clients. These occurred simultaneously due to the author’s relocation. Some responses illuminate hitherto hidden and intractable internal structures, and in others the intensity of the limit acts an impetus for the client to grasp something new. Drawing on Power’s comprehensive book: Forced Endings in Psychotherapy and Psychoanalysis (2016), the author reflects on the power and energy springing from the setting of the time boundary and the different dynamics created in client and therapist. There is acknowledgement of the pressure that this can create in the therapist and also there are reflections about what ultimately may be achieved.

This paper discusses the organisations involved in the development of application standards, European regulations and best practice guides, their scope of work and internal structures. It considers their respective visions for the requirements for future standardisation work and considers in more detail those areas where these overlap, namely human centric or integrative lighting, connectivity and the Internet of Things, inclusivity and sustainability.

Excavation at a crop-mark site found close to Annan, Dumfries and Galloway, revealed evidence of a ring-ditch containing a number of intriguing internal structures. Initially this was presumed to be a prehistoric monument, but pottery and radiocarbon dating, unexpectedly, indicated that the main structural phase of the site falls between the 11th-13th centuries AD. This suggests that a degree of caution is required when interpreting crop-mark sites on morphological characteristics alone. Moreover this excavation makes clear that morphological interpretation can have a constraining influence on excavation strategy, so caution is required when designing fieldwork programmes.

AbstractConstituting the key element of a democratic system, political parties are among entities obliged by the Polish legislator to comply with the principle of disclosure by providing public information. The main objective of this paper is to determine the level of Polish political parties’ disclosure, understood here as their willingness to disclose information on their own structures. It seems that the practice of disclosing such basic organizational data may constitute a specific measure of Polish political parties’ respect for the idea of disclosure. The subject matter of the conducted research was particular parties’ sites in the Public Information Bulletin as well as their official websites. An attempt was made to acquire data concerning party structures by way of direct contact with particular parties’ organizational units – questionnaires were sent to both central and regional/district organizational units. In order to acquire a wider perspective, the research also included data provided by the Central Statistical Office concerning political parties’ organizational structures and election manifestos. The conducted analysis was summarized in the form of a ranking of the examined political parties based on a proposed political party disclosure index. This attempt to measure disclosure on the basis of data on internal structures provided by parties themselves is of a preliminary character which, nevertheless, makes it possible to capture the general properties of the phenomenon under analysis. Among the examined parties, it is PSL, SLD, and PO that, to an acceptable degree, follow the principle of disclosure in the analysed scope (indexes at the level of 60%-80% of the maximum value). Four other parties, i.e. N, Wolność, Razem, and Kukiz’15, are on the edge of the zone making it possible to regard their disclosure as sufficient (indexes at the level of around 50% of the maximum value). In the case of PiS, whose index does not reach 20% of the maximum value, it should be concluded that this party implements the principle of disclosure at a minimum level. The ranking did not show relationships between parties’ willingness towards providing information and their sizes or positions on the political scene (parliamentary parties vs. extra-parliamentary parties).

The economic crisis showed the weaknesses of the institutional system of the European Union, raising questions about its shape. The article aims to determine whether internal structures of the EU institutions and their modes of operation are chances or barriers for effective treaty implementation and the ability of institutions to face unexpected, difficult situations. The article focuses both on the formal structure of the institutions and their human resources. The article aims to conclude if the crisis may give impetus to a significant improvement in the EU institutional system.

The introduction of the newest technologies of organic pig breeding has the basic principle of minimizing the use in pigs of chemicals, trace amounts of which in pig production adversely affect the quality of products and the health of consumers. The transition to herbal remedies, the maximum possible rejection of chemical synthesis products, is inhibited, in the main, by the relatively small spectrum of plant compounds with the investigated activity. According to the results of previous studies, six working solutions of Juglans regia L phytosupply extracts - potential phytosine disinfectants were developed: To investigate the bactericidal activity of the experimental preparations of Juglans regia, flushes were made from the internal structures and technological equipment of the housing of the pig stock of the experimental base v. Takhtaulove. Obtained samples of typical banal microflora of the pig complex were mixed to obtain a bacterial-containing suspension averaged over the concentration of microbial bodies and the spectrum of types of microflora in the microbiota. When cultured on nutrient media, with the superficial sowing of a suspension of banal microflora of a pig in the presence of a potential phytodisinfectant, processes of development of individual colonies of the microflora are observed. The amount and intensity of their development, the degree of inhibition of life, assess the level of bactericidal activity of the extracts. The highest bactericidal and fungicidal activity, and consequently, the potential efficacy as a possible disinfectant in the technology of organic pig breeding was revealed by the extracts of phytosupply Juglans regia L No. 2 (extractant - acetic acid to 5 %, nut of wax ripeness) and 4 (extractant, alcohol 20 % nutrient wax ripeness (proven after obtaining the primary extract of up to 5 % alcohol), which have bactericidal properties against gram-positive cocci and gram-negative sticks, but have a weak effect on the spore-forming bacilli. Key words: organic pig breeding, bactericidal activity, phyto-disinfectant, commonplace typical microflora of a pig complex, phyto row materials, walnut extract.
