Appearance traits in fish, those external body characteristics that influence consumer acceptance at point of sale, have come to the forefront of commercial fish farming, as culture profitability is closely linked to management of these traits. Appearance traits comprise mainly body shape and skin pigmentation. Analysis of the genetic basis of these traits in different fish reveals significant genetic variation within populations, indicating potential for their genetic improvement. Work into ascertaining the minor or major genes underlying appearance traits for commercial fish is emerging, with substantial progress in model fish in terms of identifying genes that control body shape and skin colors. In this review, we describe research progress to date, especially with regard to commercial fish, and discuss genomic findings in model fish in order to better address the genetic basis of the traits. Given that appearance traits are important in commercial fish, the genomic information related to this issue promises to accelerate the selection process in coming years.

Background: Alzheimer's disease (AD) is neurodegenerative disease brought on by a combination of changes in multiple pathways that conglomerate to promote disease progression. AD often occurs alongside comorbid diseases, most often immune or vascular in nature, which have been shown to further increase AD risk. We previously showed that known AD variants also associate with secondary diseases in these categories, including rheumatoid arthritis, ischemic myocardial infarction, and both Type 1 and Type 2 diabetes.

Background: Recent research shows that individuals exhibiting schizotypal traits (ST) are more prone to developing other psychiatric disorders such as anxiety and depression. Regarding the relationship between empathy and schizotypy, a considerable degree of heterogeneity has been observed. The objective of this study was to describe the presence of ST in college students and the relationships among ST, psychiatric symptoms, and empathy.

Romantic love plays a central role in the lives of individuals and influences decisions about lasting relationships such as marriage or cohabitation. To understand the dynamics of intimate relationships, both personality traits and attitudes toward love styles need to be explored. This cross-sectional study aimed to examine the possible differences between married/cohabiting and single individuals in terms of Dark Triad personality traits and attitudes towards love styles, and to investigate which of these factors can significantly predict participants' relationship status.

Global warming and declining rainfall in recent years have led to increased water and soil salinity in Iran agricultural lands. To address these challenges, greenhouse cultivation, particularly soilless culture, emerges as a critical solution for mitigating the effect of soil salinity and water scarcity on vegetable plant production in Iran. The aim of this experiment was to compare the growth and physiological responses of cucumber plants cultivated in both soil and soilless systems, using three distinct nutrient solutions.

Tumor suppressor BRCA2 executes homologous recombination to repair DNA double-strand breaks in collaboration with RAD51, involving exon 11 and 27. Exon 11 constitutes a region where pathogenic variants (PVs) accumulate, and mutations in this region are known to contribute to carcinogenesis. However, the impact of the heterozygous PVs of BRCA2 exon 11 on the life quality beyond cancer risk, including male fertility, remains unclear.
