[Evaluation of the regeneration process of the sciatic nerve of a mouse animal model after application of freezing, crushing or electrocoagulation damage].

The problem of regeneration of damaged peripheral nerves is an ongoing topic and has long been the subject of intensive research worldwide. This study examined the morphological and functional evaluation of the regeneration process within the damaged sciatic nerve, a mouse animal model. The effect of impaired expression of the TSC-1 gene on the process of nerve regeneration was evaluated, depending on the mode of damage.

[The mTOR pathway and transgenic animals with deletion of the TSC gene in the regeneration of the nervous system and selected models of sciatic nerve damage].

Traumatic damage to the nervous system has been a common occurrence for years, reducing patients' quality of life. The mammalian target of rapamycin (mTOR) pathway plays a key role in nervous system physiology, including by controlling nerve cell survival and differentiation. Excessive activation of the mTOR pathway leads to an increase in cell cycle protein activity and apoptosis of nerve cells.

[Assessment of metabolomics in patients with multiple sclerosis as an indicator of disease development, including relapsing-remitting, primary progressive and secondary progressive stage].

Metabolomics is a scientific field whose topics include qualitative and quantitative analysis of metabolites, defined as the total set of low-molecular-weight chemical compounds not exceeding 1500 Da. Along with genomics, transcriptomics, and proteomics, it is categorized as a field of science, currently using state-of-the-art diagnostic tools that, in the face of modern medicine, allow a holistic approach to the patient. The presence of metabolites in the analyzed biological material, in contrast to the information contained directly in the genetic material, reflects the current physiological state of the cell, and represents an integral relationship between genotype and phenotype, which can directly contribute in the future to the knowledge of the molecular basis in specific disease entities.

[Neuroprotective effect of curcumin and its potential use in the treatment of neurodegenerative diseases].

The development of methods used in molecular biology has allowed a milestone in medical and pharmaceutical sciences. Progress has also been made in the field of pharmacognosy, which places substances of natural origin contained in plant raw materials at the center of attention. The beneficial effects of some of them have been known for years, while scientific evidence of their health-promoting properties was lacking for a long time.

[Bcl-2-proteins and neurotrophins as important factors for the survival of peripheral neurons in transgenic animals].

Apoptosis is an orderly, active process with the activation of certain genes that allows the cell to follow the path of programmed death. During embryogenesis, programmed cell death templates are essential for the proper formation of organs and the functioning of the nervous system in the regression of primary or abnormal structures. Increased cell mortality in the mature nervous system can lead to various neurodegenerative diseases.

[Cerebral metabolism of glucose and selected glucose transporters in neurodegenerative diseases].

Cerebral glucose metabolism is an issue of researchers’ interest for a long time. Disturbed transport and metabolism of glucose in the brain lead to development of numerous neurological pathologies. Recently, a significant correlation between perturbed cerebral glucose metabolism and development of neurodegenerative diseases has been shown.
