“…Currently, in the literature the time scale of nutritional-intervention studies in CKD patients is variable and in most of them, this comprises between one and twenty-four weeks. For this reason, the choice of 9 weeks of treatment with EVOO and of 2 months of wash-out period has been driven by the mean time of treatment present in the literature [11,13,19,[40][41][42][43][44].…”

Chronic kidney disease (CKD) is one of the most common chronic non-communicable degenerative diseases and it represents an important risk factor for cardiovascular morbidity and mortality. The Mediterranean diet, in which extra virgin olive oil (EVOO) is the main source of vegetal fats, represents a nutritional-diet regimen that is useful for the treatment of CKD and its comorbidities. We tested two different EVOOs, characterized by a high (Synergy) and medium (Luxolio) content of minor polar compounds (MPCs), detected by HPLC-DAD-MS analysis, in 40 nephropathic patients, at a dose of 40 mL/day for 9 weeks. We evaluated the effects of these two EVOOs on renal function, body composition, oxidative stress, and inflammatory state, after 9 weeks of EVOOs consumption (T1) and after 2 months of wash-out (T2). We observed an improvement of renal function biomarkers (estimated-glomerular filtration rate, albuminuria, azotemia, uric acid), lipid profile, oxidative stress, inflammatory parameters (erythrocyte sedimentation rate, C-reactive protein) and in body composition at T1. These healthy effects were greater and persisted over time after the wash-out period in Synergy patients. The high MPC EVOO content seems to exert an antioxidant and anti-inflammatory effect in nephropathic patients and these protective actions are maintained over time.

“…Liang et al [51] suggested that hybridisation between two populations increased genetic diversity indicators such as N a , H e , and H o in oysters and significantly reduced F is . Hu et al [52] suggested that intraspecific hybridisation can cause recombination of existing genes, which is an important way to increase biodiversity. However, genetic pollution is indeed a noteworthy problem, which reminds us that we cannot cross randomly, but must develop appropriate crossbreeding strategies to avoid genetic pollution.…”

With the increasing scale of crayfish breeding, the self-propagation and “catch large and keep small” breeding patterns have led to serious degradation of the fry, so the selection and breeding of high-quality fry is very important. Selecting a population with a high genetic diversity as the base population for breeding can greatly improve the breeding efficiency. Fifteen microsatellite loci were used to understand the genetic structure and diversity of three Procambarus clarkii populations in Chongming, Shanghai; Gaoyou, Jiangsu; and Xuancheng, Anhui. The results indicated that the three populations were diverse and the number of alleles, observed heterozygosity, expected heterozygosity, Shannon information index, and polymorphic information content ranged from 4.8 to 6.2, 0.5567 to 0.6257, 0.6166 to 0.7086, 1.1292 to 1.3987, and 0.5446 to 0.6452, respectively. The Xuancheng population had the highest genetic diversity. The genetic differentiation coefficient and gene flow of the three populations were between 0.0553 and 0.1068 and 2.0908 and 4.2708, respectively, and there was extensive genetic exchange between the Chongming and Xuancheng populations. Analyses of molecular variance indicated that the genetic variation was mainly within the population (91.51%) and inter-population genetic variation accounted for 8.49%. The unweighted pair group method with an arithmetic mean clustering map was utilised based on the genetic distance between groups, and the results showed that the Gaoyou group was grouped alone, while the Chongming and Xuancheng groups were clustered together. The structural results indicated that the Chongming and Xuancheng groups had the same origin, although the Xuancheng group possessed a more complex genetic structure. This study indicated that all three populations had a high genetic diversity, with the Xuancheng population exhibiting the highest diversity. The results of the study provide a reference for the selection of base populations in breeding programs and confirm that the Xuancheng population in Anhui has a better genetic background. The selection of the Xuancheng population as one of the base populations for genetic breeding will be more efficient to accumulate superior traits.

The bay scallop and Peruvian scallop are economically important species. Interspecific hybrids of these two scallops outperformed both of their parent species in multiple growth traits but exhibited decreased fertility, which provides good models for the study of heterosis and species divergence. Genetic mapping serves as a chromosomal-level framework to investigate the molecular mechanisms of hybridization and introgression. In this study, high-resolution linkage maps were constructed for the bay and Peruvian scallops with an interspecific hybrid family. The linkage map of the bay scallop covered over 98.9% of the whole genome with 2994 mapped markers and the average marker interval of 0.32 cM. For the Peruvian scallop, 1585 markers were mapped with the average maker interval of 0.51 cM, covering 97.7% of the genome. Both the two linkage maps have 16 linkage groups, corresponding to the haploid chromosome number of the two species. Approximately, 54.5% of markers exhibited significant deviation from the expected Mendelian ratio of segregation, lending insights into the intrinsic incompatibility between the two species. QTLs related to growth and shell coloration were detected, which could explain 13.1% and 74.9% of the phenotypic variance, respectively. This represents important information for further evaluation. These findings are an important addition to the genomic resources for scallop genetic studies, and are especially useful for investigations on genomic incompatibility for hybridization, genome evolution of closely related species, and genetic enhancement programs in aquaculture.
