Encephalitis is a condition with a variety of etiologies, clinical presentations, and degrees of severity. The causes of these disorders include both neuroinfections and autoimmune diseases in which host antibodies are pathologically directed against self-antigens. In autoimmune encephalitis, autoantibodies are expressed in the central nervous system. The incidence of this disease is approximately 4% of all reported cases of encephalitis. Autoimmune encephalitis can be induced by antibodies against neuronal surface antigens such as N-methyl-D-aspartate-activated glutamate receptors (NMDAR), α-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptors (AMPAR) or gangliosides GQ1b, DPPX, CASPR2, LGI1, as well as by antibodies against neuronal intracellular antigens. The paper presents a number of both mental and neurological symptoms of autoimmune encephalitis. Moreover, the coexistence of psychoses, neoplastic diseases, and the methods of diagnosing autoimmune encephalitis are discussed. Attention was also drawn to the fact that early diagnosis, as well as early initiation of targeted treatment, increases the chance of a successful course of the therapeutic process. Strategy and Methodology: The articles on which the following paper was based were searched using search engines such as PubMed and Medline. Considering that anti-NMDAR antibodies were first described in 2007, the articles were from 2007 to 2023. The selection of papers was made by entering the phrases “autoimmune encephalitis and psychosis/paraneplastic syndromes or cancer”. The total number of articles that could be searched was 747, of which 100 items were selected, the most recent reports illustrating the presented topic. Thirty-four of them were rejected in connection with case reports or papers that could not be accessed.

The aim of this study is to review and analyze the pleiotropic effects of TGF-β in physiological and pathological conditions of the liver, with particular emphasis on its role in immune suppression, wound healing, regulation of cell growth and differentiation, and liver cell apoptosis. A literature review was conducted, including 52 studies, comprising review articles, in vitro and in vivo studies, and meta-analyses. Only studies published in peer-reviewed scientific journals were included in the analysis. TGF-β is a pleiotropic growth factor that is crucial for the liver, both in physiology and pathophysiology. Although its functions are complex and diverse, TGF-β plays a constant role in immune suppression, wound healing, and the regulation of cell growth and differentiation. In concentrations exceeding the norm, it can induce the apoptosis of liver cells. Increased TGF-β levels are observed in many liver diseases, such as fibrosis, inflammation, and steatosis. TGF-β has been shown to play a key role in many physiological and pathological processes of the liver, and its concentration may be a potential diagnostic and prognostic marker in liver diseases.

Sleep is a key component of everyone's health. It plays an important role in the body's recovery, improvement of cognitive function, and overall well-being. This thesis explores various aspects of sleep, focusing on its physiology, functions, and role in daily life. The paper includes detailed analyses of the effects of sleep on memory, the effects of deprivation, and techniques to improve sleep quality, such as sleep duration and regularity, minimising alcohol and caffeine intake, and meditation practices. The link between sleep and physical activity is also proving to be extremely important. Regular activity affects sleep quality and mental health. Finally, sleep is the foundation of health and well-being. Despite the wealth of information we already have, the importance and role of sleep presented in the following article demonstrate that this area should invariably be the subject of further research to help us gain an even better understanding of, and therefore influence, the quality of our sleep.

The effects of physical activity on brain function, the mechanisms involved, adaptations, and clinical implications are topics of great importance given the increasingly common sedentary lifestyle. This paper explores these relationships, starting with the evolutionary aspects of brain development in the context of physical activity. It discusses a variety of forms of exercise, from intense exercise to daily NEAT (non-exercise activity thermogenesis). A key issue is neuroplasticity, which plays an important role in adaptation to external stimuli. The article identifies key neurotrophic factors, such as BDNF (brain-derived neurotrophic factor) and VEGF (vascular endothelial growth factor), which are regulated by physical activity and contribute to improved cognitive function and mental health. The paper demonstrates the multifaceted effects of physical activity on neuroplasticity and brain health.
