Research topics
The use of ionising radiation for the diagnosis and treatment of lymphoma and brain tumours has significantly improved healthcare and patient outcomes. Ionising radiation is now relied on heavily for patient diagnosis and treatment. We investigate the effects of radiation exposure on patients, workers and carers as well as the public and the environment during patient management. It will organise high-level multidisciplinary training in the field of radiation dosimetry, risk appraisal and radiation protection. More specifically, we develop new dosimetry and risk appraisal methods and tools. Artificial intelligence (AI) will be used to determine the radiation burden on patients, and new techniques will be designed to manage data from radiation therapy sessions.

Research topics
Our group is a multidisciplinary research team operating at the interfaces of biophysics, nanobiology and nanomedicine. In our research, we focus on studying the mechanism of permeability of the outer bacterial membrane by antibacterial dendritic nanoparticles eg. dendrimers. Dendrimers, by virtue of the unique ramified nanostructure and multivalent cooperativity, are emerging as promising nanomaterials thanks to their antibacterial activity and their ability to deliver antibacterial like phage-endolysin. As antibacterial resistance has become a global threat, there is a pressing need for new antibacterial agents to treat bacterial infection and overcome drug resistance. Drug resistance is mainly due to the presence of an additional outer membrane (OM) in Gram-negative bacteria. Therefore, we study the antibacterial properties of cationic dendrimers with antibacterial activity closely related to membrane permeabilization or membrane disruption.
Moreover, we are focusing on study the synergic effect of antibacterial dendritic nanoparticles together with phage-endolysin as a new tool to kill antibiotic resistance bacteria. Another area of our research is the study of the nanotoxicity of dendritic nanoparticles and the study of the effect of dendronization of selected proteins.

Research topics
Optical properties of chemical substances are widely used at present for assays thereof in a variety of scientific disciplines. Instrumental optical methods, based on measurement of selective absorption of radiation (absorptiometry), the twist angle of polarised light surface (polarimetry) or intensity of substance-emitted fluorescent radiation (fluorimetry), constitute the canon of standard analytical techniques, used in biological sciences. One of the measurement techniques used in physical sciences, with a potential for new applications in biology, is laser interferometry. This method, based on the phenomenon of wave interference, enables quantitative substance assays by means of measurement of the difference between light refractive indexes for the studied and control substances. Moreover, properties of laser-generated radiation, i.e. low beam divergence, narrow spectral band and high degree of coherence all have a positive influence on assay sensitivity. In studies, we used the nowel laser interferometry system to measure the diffusion properties of new antibacterial agents and anticancer drugs through bacterial biofilm and eukaryotic cell monolayer, respectively. These results are compared with the biological effect of testing agent by microbiological cultivation methods, flow cytometry or molecular biology methods.

Acute Myeloid Leukemia (AML) is the most commonly diagnosed aggressive leukemia. It originates from a single dominant mutation, and then transfers into a complex disease during which abnormally proliferating cells acquire collaborative mutations with different clinical/biological importance. Quick and exact profiling of patients mutational profile is important for the introduction of precise and personalized therapies. The spectrum of possible mutations that are observed in AML results in fact that the significance of many of them remain unclear. We focus on investigation the molecular mechanisms (mutations, translocations and genes expression) driving AML development using Next Generation Sequencing (NGS) that allows testing genetic diversity in multiple genes parallelly with significantly high sensitivity of detections. Testing the relationship between patients mutational profiles and course of diseases/therapies outcomes will help in classification of mutations as prognostic factors and searching of new therapeutic targets. In addition use of NGS will allow also to investigate the occurrence of minimal residual disease (MRD) after treatment, that is important for risk stratification and treatment planning.
Colorectal cancer is one of the most commonly diagnosed malignant neoplasms in men and women. Despite the availability of colonoscopy, most cases are diagnosed at an advanced stage, when metastases to other organs are already present. Unfortunately, recent studies indicate that 80% of colorectal cancer cases metastasize in very early stage of disease. The aim of the research is to find out about the molecular biology of colon cancer and the interaction of cancer cells with cells of the immune system and the microbiome. Understanding these complex interactions will help identify new therapy targets and strategies for early detection of colorectal cancer.The next topic of our work is in vitro analysis of the anticancer properties of transition metal complexes and nanoparticles. In our study we focus on cyto- and genotoxic activities of new antitumor agents on DNA and protein level as well as mechanism of their action using normal and cancer cell lines.

Research topics
The research focuses mainly on the activity of the lysosomal system (with particular emphasis on the processes of autophagy) in cells and tissues of animals after loading with compounds of plant origin with potential antitumor activity (vinblastine, vincristine, taxol, colchicine, iscador, anthraquinones) and after combined action of these compounds with selected components of antioxidant protection. Moreover, the range of changes in cells induced by glucocorticosteroids, antihistamines, vanadium, and magnesium compounds, and ionizing radiation are analyzed at the ultrastructural and biochemical levels. In vitro and in vivo studies include the assessment of the dynamics of ultrastructural and biochemical changes in the lysosomal compartment, peroxisomes, Golgi apparatus, microtubules and mitochondria, and the regulation of autophagy and apoptosis in normal and neoplastic cells. The research also includes an evaluation of the correlation of allergen concentration in urban agglomerations with cytological changes in selected groups of patients, before and after treatment with antihistamines.
