Summary: This study investigated the genetic polymorphism of CSN2 and CSN3 genes in Maghrebi camels using PCR-SSCP and DNA sequencing tools. The results identified different genotypes and SNP variants in these genes, and showed that specific alleles had an impact on milk composition traits, such as milk fat. The findings suggest that genetic discrimination of these genes can be used as a valuable marker in selecting superior camels to improve milk composition.

Summary: This study identified suitable reference miRNAs for quantitative expression analysis of miRNAs in Japanese flounder (Paralichthys olivaceus). Through miRNA-Seq analysis and literature search, 10 candidates were selected and their expression stability was evaluated using qRT-PCR and multiple methods. The results showed that miR-22-3p and miR-23a-3p were suitable reference miRNAs for both normal tissues and livers infected with E. tarda in P. olivaceus. These findings provide valuable information for future miRNA expression analysis in P. olivaceus.

Summary: This study found that variations in the leptin gene can impact milk traits in cows, particularly affecting protein content. While there was no association between LEP genotypes and milk yield and fat percentage, cows with the AB genotype had lower protein content in their milk. This research suggests that variations in exon 3 of LEP may be useful for selecting cows for improvement in key milk traits.

Summary: This study proposed an improved Gradient Boosting Regression Tree (IGBRT) method to invert copper contents using hyperspectral remote sensing. By introducing the iron element as an intermediate variable, a relationship between iron and copper contents was established to improve accuracy and efficiency. The results showed that the IGBRT algorithm had a higher coefficient of determination (R-2) and increased learning efficiency compared to traditional methods, providing important implications for remote sensing inversion of copper contents in uninhabited areas.

Summary: Seed longevity is important for preserving genetic diversity, and it is acquired during late maturation through the dismantlement of chloroplasts. The gene ABI4 plays a role in coordinating this process in Medicago truncatula, as its mutation leads to increased chlorophyll retention and reduced longevity. The study also found that the shutdown of photosynthesis during maturation is crucial for the acquisition of seed longevity.

Summary: This study focused on evaluating the responses of the cockle, Cerastoderma glaucum, to metal exposures at different contamination levels in the Gulf of Gabes. The study examined the physiological state, bioaccumulation of metals, histological changes in gametogenesis and sexual maturity, and gene expression of key enzymes and proteins involved in responses to environmental stressors. Results showed a decrease in physiological status, consistent bioaccumulation of metals with contamination gradient, minimal differences in reproductive cycle, and varied patterns of gene expression. Overall, these findings suggest that measures of physiological condition, sex ratios, and gene expression could serve as biomarkers for assessing metal impacts on cockles, but further proteomics studies are needed.

Summary: Natural astaxanthin is richer than synthetic astaxanthin, but cultivating it in photobioreactors is expensive and downstream processing techniques for solubilization are not cost-effective. As a result, the cost of astaxanthin is high, leading pharmaceutical and nutraceutical companies to opt for synthetic astaxanthin. This review discusses the chemical character of astaxanthin, more cost-effective cultivating techniques, and its bioavailability. Moreover, the antioxidant properties of this microalgal product against various diseases are discussed, which make it a promising drug for reducing inflammation and its consequences.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
