Pillar 3: Does banking regulation support stakeholders' interest in banks financial and risk profile?

The paper examines the interest of the commercial banks' stakeholders in Pillar 3 disclosures and their behaviour during the timing of serious market turbulence. The aim is to discover to which extent current banking regulation supports stakeholders' interest in the information required by regulators to be disclosed. The examined data consists of log files that were pre-processed using web mining techniques and from which were extracted frequent item sets by quarters and evaluated in terms of quantity.

Improving fake news classification using dependency grammar.

Fake news is a complex problem that leads to different approaches used to identify them. In our paper, we focus on identifying fake news using its content. The used dataset containing fake and real news was pre-processed using syntactic analysis.

Using of n-grams from morphological tags for fake news classification.

Research of the techniques for effective fake news detection has become very needed and attractive. These techniques have a background in many research disciplines, including morphological analysis. Several researchers stated that simple content-related n-grams and POS tagging had been proven insufficient for fake news classification.

Micropropagation of transgenic lettuce containing HBsAg as a method of mass-scale production of standardised plant material for biofarming purposes.

Micropropagation protocol of transgenic lettuce bearing S-, M- and L-HBsAg was developed for increased production of uniformised material for oral vaccine preparation. Effective manufacturing of plant-based biopharmaceuticals, including oral vaccines, depends on sufficient content of a protein of interest in the initial material and its efficient conversion into an administrable formulation. However, stable production of plants with a uniformised antigen content is equally important for reproducible processing.

Immunogenicity of parenterally delivered plant-derived small and medium surface antigens of hepatitis B virus.

Intramuscularly delivered plant-derived M-HBsAg was compared to S-HBsAg, and as a result elicited specific anti-preS2 antibodies and significantly higher titre of anti-HBs antibodies, together with IgG isotype profile indicating some Th1 polarisation, apart from the main Th2 response. HBV prevalence is still threatening, regardless of prevention programmes using vaccines containing S-HBsAg, supplemented by third-generation vaccines, comprising also M- and L-HBsAg. Plant expression systems offer a cost-effective production option of the antigens.

Plant expression, lyophilisation and storage of HBV medium and large surface antigens for a prototype oral vaccine formulation.

Current immunisation programmes against hepatitis B virus (HBV) increasingly often involve novel tri-component vaccines containing-together with the small (S-HBsAg)-also medium and large surface antigens of HBV (M- and L-HBsAg). Plants producing all HBsAg proteins can be a source of components for a potential oral 'triple' anti-HBV vaccine. The objective of the presented research was to study the potential of M/L-HBsAg expression in leaf tissue and conditions of its processing for a prototype oral vaccine.

Low-dose oral immunization with lyophilized tissue of herbicide-resistant lettuce expressing hepatitis B surface antigen for prototype plant-derived vaccine tablet formulation.

Efficient immunization against hepatitis B virus (HBV) and other pathogens with plant-based oral vaccines requires appropriate plant expressors and the optimization of vaccine compositions and administration protocols. Previous immunization studies were mainly based on a combination of the injection of a small surface antigen of HBV (S-HBsAg) and the feeding with raw tissue containing the antigen, supplemented with an adjuvant, and coming from plants conferring resistance to kanamycin. The objective of this study was to develop a prototype oral vaccine formula suitable for human immunization.

Nanogram doses of alum-adjuvanted HBs antigen induce humoral immune response in mice when orally administered.

Mucosal immunity elicited by plant-based and other orally administered vaccines can serve as the first line of defense against most pathogens infecting through mucosal surfaces, but it is also considered for systemic immunity against blood-borne diseases such as hepatitis B (HB). Previous oral immunization trials based on multiple administration of high doses of HBs antigen elicited an immune response; however, a reproducible and long-lasting immunization protocol was difficult to design. The objective of this study was to evaluate the effect of dose and timing of orally delivered alum-adsorbed antigen on the magnitude of the anti-HBs humoral response.

Agrobacterium-mediated transformation of yellow lupin to generate callus tissue producing HBV surface antigen in a long-term culture.

The idea of an oral vaccine administered as a portion of plant tissue requires a high level of antigen production. An improved protocol for the induction of transgenic yellow lupin calli or tumours, reaching 44% of transformation rate, is presented here. It has been developed by using the nptII marker gene and the uidA reporter gene as well as various Agrobacterium strains and plant explants.

Efficiency of transformation of Polish cultivars of pea (Pisum sativum L.) with various regeneration capacity by using hypervirulent Agrobacterium tumefaciens strains.

An Agrobacterium-mediated transformation method of pea has been developed for several edible and fodder cultivars of pea (Pisum sativum L.), characterized previously in their potential for regeneration via organogenesis. The most appropriate explant, which was susceptible to Agrobacterium infection and capable of regenerating transgenic plants, turned out to be a slice of an immature embryo, including the embryo axis and the basal part of a cotyledon.
