Chemical analysis showed that pH, values, myosin turbidity, carbonyl content, and surface hydrophobicity elevated in hooked, trawl-net, and radar-net hairtail (, HH, TH, and RH) muscles with the prolonged cryopreservation time (-18℃, 120 d). In contrast, , values, textural properties, and myosin solubility existed decreasing trends. Microstructural results showed that freezing resulted in disordered myofibrils, decreased collagen fibers, widened myofibrillar space, and increased fragmentation in hairtail muscles.

The fungal cell wall consists of glucans, mannoproteins, and chitin and is essential for cell viability, morphogenesis, and pathogenesis. The enzymes of the GH72 family are responsible for ß-(1,3)-glucan elongation and branching, which is crucial for the formation of the glucan-chitin polymer at the bud neck of yeast cells. In the human fungal pathogen Candida albicans, there are five GH72 enzyme-encoding genes: , and .

Chitinases are hydrolytic enzymes that break down glycosidic bonds in the chitin. Chitinases are classified into three categories, endochitinases, exochitinases and N-acetylglucosaminases, according to the manner in which the enzyme cleaves the chitin polymer.

Springiness, chewiness, myofibrillar active sulfhydryl content, and Ca-ATPase activity significantly decreased, suggesting that cold stress altered muscle proteins. Compared with fresh hairtail (FH), 66 common differentially abundant proteins (DAPs) had lower abundances in chilled (3 d; CSH) and frozen (120 d; FSH) hairtail, including myosin binding proteins, filamins, actinin, troponin, and muscle-restricted coiled-coil protein.

Chemical results indicated that the PV and TBARS values in hairtail muscle significantly increased during 120 days of frozen storage. Lipidomics results detected 1223 lipids in hairtail muscle assigned to 26 lipid categories, including 261 triglycerides (TGs), 251 phosphatidylcholines (PCs), 153 phosphatidylethanolamines (PEs), and 66 diglycerides (DGs).

With the development of data information acquisition technology, ultrasound imaging is increasingly susceptible to speckle noise, which leads to defects, such as low resolution, poor contrast, spots, and shadows, which affect the accuracy of physician analysis and diagnosis. To solve this problem, we proposed a frequency division denoising algorithm combining transform domain and spatial domain.

Activation of this sensor complex induces a proteolytical complex composed of Rim13 and Rim20 and leads to the C-terminal processing and activation of the transcription factor Rim101. Deletion mutants for RIM8, RIM9, RIM13, RIM20, RIM21 and RIM101 causes yeast cells to be sensitive to calcium stress, but how they regulate calcium sensitivity remain unknown.

Electronic nose analysis indicated that CO treatments maintained the stability of the overall volatile flavor profiles in frozen mackerel. Protein oxidation analysis suggested that the incorporation of CO significantly retarded the rapid decrease of Ca-ATPase activity and active sulphydryl (A-SH) contents while also effectively inhibiting the increases in carbonyl content and surface hydrophobicity of myofibrillar proteins (MPs) compared to the control treatments.
