Skin hyperspectral imaging and machine learning to accurately predict the muscular poly-unsaturated fatty acids contents in fish.

The polyunsaturated fatty acids (PUFAs), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are critical determinants of the nutritional quality of fish. To rapidly and non-destructively determine the muscular PUFAs in living fish, an accuracy technique is urgently needed. In this study, we combined skin hyperspectral imaging (HSI) and machine learning (ML) methods to assess the muscular PUFAs contents of common carp.

Single-Nucleus RNA Sequencing Reveals the Transcriptome Profiling of Ovarian Cells in Adolescent .

The common carp () is a crucial freshwater species cultivated worldwide for food consumption. Female carp have better growth performance than males, which fascinates scholars to uncover the mechanism of gonadal differentiation and produce mono-sex populations. However, the mechanism of ovarian development at single-cell resolution is limited.

Effects of adsorption of O and HO molecules on the corrosion behavior of the NiTi alloy surface: a DFT investigation.

The influence of O and HO adsorption significantly affects the electrochemical corrosion of the NiTi alloy, with unresolved corrosion disparities between the NiTi-B and NiTi-B19' phases. Density functional theory (DFT) calculations are utilized in this investigation to explore the adsorption of O atoms at varying coverages on the NiTi-B(110) and NiTi-B19'(010) surfaces. The goal is to elucidate their oxidation behavior differences.

Analysis of Chromatin Accessibility and DNA Methylation to Reveal the Functions of Epigenetic Modifications in Gonads.

Epigenetic modifications are critical in precisely regulating gene expression. The common carp () is an economically important fish species, and females exhibit faster growth rates than males. However, the studies related to epigenetic modifications in the common carp gonads are limited.

Differential Expression of miRNAs, lncRNAs, and circRNAs between Ovaries and Testes in Common Carp ().

Female common carp grow faster than male individuals, implying that rearing females could be more profitable in aquaculture. Non-coding RNAs (ncRNAs) serve as versatile regulators with multiple functions in diverse biological processes. However, the roles of ncRNAs in the sex differentiation of common carp are less studied.

DFT investigation of the dissolution trends of NiTi alloys with the B and B19' phases during the initial oxidation stage.

The selective corrosion of NiTi alloys was studied using density functional theory calculations, and the dissolution trends of the NiTi-B and NiTi-B19' phases in the initial oxidation stage were compared to predict their corrosion difference. The dissolution process of Ni and Ti was simulated by creating Ni or Ti vacancies on the unoxidized and oxidized NiTi alloy surfaces. The results show that the surface vacancy formation energy of Ti vacancies is higher than that of Ni vacancies, indicating that Ti is more difficult to dissolve than Ni.

Comparison of P2Y12 Inhibitors in Acute Coronary Syndromes in the Australian Population.

Background: Clopidogrel in combination with aspirin after acute coronary syndromes (ACS) reduces recurrent ischaemic events compared to aspirin alone. Further reductions in events have been demonstrated when clopidogrel is replaced by ticagrelor or prasugrel albeit with increases in bleeding. There are few studies documenting the patterns of use of P2Y12 inhibitors or their association with outcomes in the Australian population.

Preparation, characterization and evaluation of cellulose nanocrystal/poly(lactic acid) in situ nanocomposite scaffolds for tissue engineering.

Cellulose nanocrystal (CNC)/poly(lactic acid) (PLA) in situ nanocomposite scaffolds were fabricated by in situ polymerization of lactic acid and CNC which was directly utilized as aqueous suspension, followed by a process of thermally induced phase separation. The CNC/PLA in situ nanocomposite porous scaffolds were characterized by mechanical test, protein adsorption, hemolysis test, in vitro degradation measurement, TEM, FTIR, SEM and WAXD. Compared to the PLA scaffold, the CNC/PLA in situ nanocomposite scaffolds showed a greatly increased compression modulus, an improved hemocompatibility and protein adsorption capacity.

Alternative splicing of GnRH2 and GnRH2-associated peptide plays roles in gonadal differentiation of the rice field eel, Monopterus albus.

The rice field eel, Monopterus albus, is a protogynous hermaphrodite fish, in which the gonads are initially female ovaries which then transform into male testes. The exact mechanisms governing sex reversal in the rice field eel are unknown. In this study, a novel alternative splicing variant of GnRH2 (GnRH2-SV), retaining the second intron, was discovered in the gonad of the rice field eel.
