Crystal structure of hydrocortisone 17-butyrate

2014

In the title compound, C25H36O6, the two central cyclohexane rings exhibit a chair conformation. The terminal cyclohexene and cyclopentane rings are in half-chair and envelope conformations (with the C atom bearing the methyl substituent as the flap), respectively. The methyl group of the butyrate chain is disordered over two orientations, with a refined occupancy ratio of 0.742 (6):0.258 (6). Intramolecular O—H...O and C—H...O hydrogen bonds are observed. In the crystal, molecules are linked by O—H...O hydrogen bonds into chains running parallel to theaaxis.

Angioedema Coexisting Chronic Spontaneous Urticaria Negatively Influences Patients’ Sense of Coherence, What Results in Susceptibility to Anxiety Sym…

2021

Background: Angioedema coexisting chronic spontaneous urticaria (CSU) is proved to result in patient anxiety occurrence, but the mechanisms and susceptibility patterns are unknown. Sense of coherence (SOC) is one of methods of coping with stress and is defined as a person’s general orientation toward life. We decided to assess SOC disturbances in CSU patients in the context of possible angioedema association. Methods: The study comprised 71 CSU subjects. To analyze disease activity, the Urticaria Activity Score seven-day assessment questionnaire (UAS7) was used. For anxiety assessment, the STAI questionnaire was used. The SOC-29 questionnaire, consisting of questions related to comprehensib…

Characterization of a Double Metal Cyanide (DMC)-Type Catalyst in the Polyoxypropylation Process: Effects of Catalyst Concentration

2014

The alkaline catalysts commonly applied to alkoxylation are characterized by a limited spectrum of activity caused by an irreversible termination of the polyether chains. The presented results show that double metal cyanide (DMC) catalysts reduce or eliminate the aforementioned adverse rearrangement of hydroxyl groups. Moreover, DMC catalysts indicate high activity at low concentrations (ppm range), as expressed by high polymerization rates. It was demonstrated that decreased concentrations of DMC catalyst irreversibly influence its reactivity and the dispersity of the obtained products, as exemplified by the production and determination of selected polyoxypropylenediols at different concen…

Structural and functional diversity of Bacillus thuringiensis toxins on animal, plant and microbial cells

2018

Debido a los efectos nocivos de los insecticidas químicos en los ecosistemas y sobre los organismos beneficiosos, la implementación de agentes de control biológico ha recibido considerable atención. Entre los agentes de control biológico, se ha dedicado gran interés a los entomopatógenos, debido a su potencial para controlar plagas agrícolas y domésticas, vectores de enfermedades humanas y animales, sin introducir material no degradable en el medio ambiente. Bacillus thuringiensis (Bt) es el agente de control microbiano comercial más utilizado en la actualidad, con efectividad contra diferentes especies de insectos plaga. Las cepas de Bt producen cristales paraesporales proteináceos durante…

Ochotnicze Hufce Pracy – instytucja państwowa dla młodzieży i pracy z młodzieżą

2019

The article presents Voluntary Labour Corps (OHP) as an educational institution of the labour market in Poland. It attends difficult, young people who are socially excluded. The OHP is seen as the institution of the second chance, which embraces the needs of young people in a competent and complex way. It concentrates on providing the youth with proper education and preventing them from further social exclusion. The institution undertakes actions to include the youth in normal, adult life. Research shows that it is effective in its work and more than half of the graduates obtain a stable professional and social position

Increased carrier peptide stability through ph adjustment improves insulin and pth(1-34) delivery in vitro and in vivo rather than by enforced carrie…

2020

Oral delivery of therapeutic peptides is hampered by their large molecular size and labile nature, thus limiting their permeation across the intestinal epithelium. Promising approaches to overcome the latter include co-administration with carrier peptides. In this study, the cell-penetrating peptide penetratin was employed to investigate effects of co-administration with insulin and the pharmacologically active part of parathyroid hormone (PTH(1-34)) at pH 5, 6.5, and 7.4 with respect to complexation, enzymatic stability, and transepithelial permeation of the therapeutic peptide in vitro and in vivo. Complex formation between insulin or PTH(1-34) and penetratin was pH-dependent. Micron-size…

Aktywność celowa a dobrostan psychiczny

2020

The central problem dealt with in this monograph is the question connected with the possibilities of raising people’s psychological well-being. In recent years there has been a lot of research conducted which proved that taking up an intentional activity brings positive effects for the psychological well-being. Simultaneously, a good number of researchers adhere to the thesis advancing a steady potential level of happiness and the lack of possibility of its lasting change. The model of dependence between an intentional activity and well-being is founded on the conception of happiness deriving from the frontiers of eudaimonic and hedonic schools, whereas the theory consolidating the base of …

The need for information in purchase situation and the information behavior in front of the shelf : use and effects of electronic interactive communi…

1999

The classic approach of buying behavior supposes that the consumption value derives from the evaluation of the technical, functionnal and symbolic features of the product. But, most of recents works use an experiential approach, for which the anticiped situation of consumption or use and the self concept are the essential elements of the consumption value. This thesis, devoted to information behavior in buying situation, attemps to conciliate these two paradigms until here opposite. The first part of this search investigates the concept of need for information. Its results, according to us, the activation ot two schemes, the first concerning the product acquisition, the second relative to t…

MODELING MANAGERIAL ACTIVITY, A CHALLENGE OR A NEED INTO THE INTERCONECTED ECONOMIC SPACE

2009

In the European economic area, which becomes more and more interconnected, the management system provides ways of obtaining a performance which, on changing the size of the firm, sometimes prove to be inadequate. During that lapse of time from triggering the action when the results can be measured should be as small continuously decreasing. The information required to be used in the decision support are required more avid. The manager will use different models for measurements of indicators of discrete evaluation, but it proves that not to be the best solution. Only the availability of this information will enable them to make better decisions, and by changing the way of how the decision ma…
