The first part provides a glimpse of the long-awaited unified theory, which explains the parallel activation of different levels of the universe: intellectual (humans), psychological (animals), biological (vegetation), physical (matter), and cosmological (energies) levels, whereas in the conventional approach, the physical and cosmological levels are grouped into the same category. This paper explains the evolution and structure of elementary physical particles (EPPs) based on the evolution and structure of elementary biological particles (cells). The second part of the paper explains the structure and ingredients of the PPE, which are responsible for the creation of the following four fields, as suggested by the author: visibility, forcibility (magnetism), the fullness field, and the hollowness field. All these fields comprise different unknown cosmological substances. These cosmological fields are present in all physical entities and are responsible for all kinds of physical activations. Finally, the paper explains the evolution of electromagnetic waves, electromagnetic fields, gravitation, and repulsion (repulsive gravitation). The theory is consistent with all previously conducted experiments and systematically unfolds several mysteries, thereby demonstrating the validity of the proposed theory. tromagnetic waves, and mass. The present paper elucidates that EPPs are not point particles, but possess positive mass and an internal cosmological structure. The paper presents a modified model of EPP, with the placement of different energy fields therein, and the placement of energy fields is responsible for all physical properties. During the journey of evolving the structure of the EPPs, the paper automatically solves several quantum mysteries, including the unitarity of “four fundamental forces” and “string theory”.","PeriodicalId":19083,"journal":{"name":"Natural Science","volume":"158 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80136641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypoxia therapy is a potentially novel therapeutic strategy for a variety of pathologies including: mitochondrial disorders, exercise training, and mild cognitive impairments. Mitochondrial dysfunction, hyperkinetic movements, and cognitive impairments are hallmarks of seizures and status epilepticus (SE). A seizure can be considered uncontrolled electrical activity in the brain and SE is a seizure lasting more than 30 minutes, or multiple seizures without regaining con-sciousness in between. We examined the possibility of using the Pilocarpine model for seizure like activity on brown planaria (Dugesia tigrine). Pilocarpine is a muscarinic acetylcholine receptor agonist capable of creating seizure related brain damage. We utilized 5 mM dosages of pilocarpine and then measured open field behaviour for 3 minutes. Mobility and aversive hyperkinetic movements were observed throughout the measurement phase. After exposure to 5 mM pilocarpine, the planaria displayed behaviours consistent with seizures (e.g. aversive hyperkinetic movements and decreased mobility). Additionally, we measured the effects of an acute hypoxic event on Planaria behaviour. We used 25% carbonated water to create a hypoxic environment for the planaria and then measured mobility and hyperkinetic movements for 3 minutes. We noted that exposure to the hypoxic environment produced no changes in behaviour. However, the aversive hyperkinetic movements produced with pilocarpine administration were completely absent when a brief (3 minutes) hypoxic episode followed the pilocarpine exposure (p < 0.05). Aversive behaviours remained present when the ordering of pilocarpine and hypoxia were counterbalanced. This ordering effect was consistent across 40 trials. Further evaluation of the pilocarpine seizure model and intermittent hypoxia on planarian behaviour is warranted.","PeriodicalId":19083,"journal":{"name":"Natural Science","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89639942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration levels of cholyglycine and total bile acid in each group were detected, and the differences among each group were compared. Results: By statistical analysis, serum CG concentration in viral hepatitis group, cirrhosis group, primary liver cancer group and other hepatobiliary diseases group was significantly higher than that in asymptomatic HEPATITIS B carriers and healthy control group, the differences were statistically significant (p < 0.05).
