Traditional methods of experimentally testing these conditions are time-consuming, labor-intensive and costly, necessitating advanced optimization strategies. Recently, the rapid development of computational tools has significantly accelerated the optimization process for mRNA vaccines. In this review, we systematically examine computation-aided approaches for optimizing mRNA components, including coding and non-coding regions, and for improving the efficiency of lipid nanoparticle (LNP) delivery systems by focusing on their composition, ratios, and characterization.

Additionally, some literature suggests that undernutrition during later life or adulthood may lead to metabolic consequences, including diabetes, despite an individual's normal nutritional status earlier in life. Notably, individuals with diabetes and undernutrition show some unique features that do not fit the usual phenotype of type 2 diabetes mellitus - such as a low body mass index of <18.5 kg/m<sup>2</sup>, resistance to ketosis, and low serum C-peptide levels. Many global descriptions of this unique phenotype have led to a controversy that 'Undernutrition-associated diabetes mellitus' is a distinct form of diabetes, deserving a separate diabetes category in the WHO classification of diabetes. However, a few investigators argue that undernutrition-associated diabetes mellitus is one of the variants of the classical forms of diabetes. The second controversy is whether adult undernutrition is independently associated with metabolic abnormalities. Its pathophysiology has been difficult to determine, given confounding factors such as infections that can complicate the direct effects of malnutrition. Studies have shown that insulin deficiency due to pancreatic β cell impairment is likely to contribute to the development of undernutrition-associated diabetes. To examine these controversies, further research is warranted to understand the role of undernutrition in the pathogenesis of undernutrition-associated diabetes. This review aims to shed more light on these controversies, focusing on whether diabetes in malnourished individuals represents a distinct diabetes category and the association between malnutrition and diabetes in adults.</p>","PeriodicalId":49694,"journal":{"name":"Physiology","volume":" ","pages":""},"PeriodicalIF":5.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143574417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Altogether, the balance of SUMOylation states among relevant ion channels can result in graded biophysical effects that tune excitability and contribute to a range of disease states including cardiac arrhythmia, epilepsy, pain transmission, and inflammation.

Although these insects vary in their reliance on atmospheric oxygen, with many having the ability to extract dissolved oxygen directly from the water, all retain an internal air-filled respiratory system, their tracheal system, due to their terrestrial origins. However, carrying air within their tracheal system, and even augmenting this volume with additional air bubbles carried on their body, dramatically increases their buoyancy, which can make it challenging to remain submerged. But by manipulating this air volume a few aquatic insects can deliberately alter or regulate their position in the water column. Unlike cephalopods and teleost fish that control the volume of gas within their hydrostatic organs by either using osmosis to pull liquid from a rigid chamber or secreting oxygen at high pressure to inflate a flexible chamber, insects have evolved hydrostatic control mechanisms that rely either on the temporary stabilization of a compressible air bubble volume with O<sub>2</sub> unloaded from hemoglobin or on the mechanical expansion and contraction of a gas-filled volume with rigid, gas-permeable walls. The ability to increase their buoyancy while submerged separates aquatic insects from the buoyancy compensation achieved by other air-breathing aquatic animals that also use air within their respiratory systems to offset their submerged weight. The mechanisms they have evolved to achieve this are unique and provide new insights into the function and evolution of mechanochemical systems.</p>","PeriodicalId":49694,"journal":{"name":"Physiology","volume":" ","pages":"0"},"PeriodicalIF":5.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
