Two women, one 27 years old (case 1) and the other 20 years old (case 2), were evaluated due to right lower quadrant pain. The lactate dehydrogenase level was increased in case 1 and the dihydroepiandostrone level was increased in both cases. Preoperative transvaginal ultrasonography revealed solid masses, but the tumour markers were within normal limits. At laparoscopy, oedematous ovaries were diagnosed in both cases. Untwisting of the ovaries and laparoscopic wedge resection combined with frozen section analysis resulted in conservation of the ovaries in both cases. The patients are symptom-free after 1 year of follow-up.

Female reproduction comes at great expense to energy metabolism compensated by extensive organ adaptations including intestinal size. Upon mating, endocrine signals orchestrate a 30% net increase of absorptive epithelium. Mating increases production of the steroid hormone Ecdysone released by the Drosophila ovaries that stimulates intestinal stem cell (ISC) divisions.

The zig-zag eel exhibits both sexual dimorphism and sex reversal, making it crucial to understand the mechanisms of sex determination and differentiation. Additionally, the wild populations of the zig-zag eel are significantly declining, emphasizing the need for urgent conservation efforts. In this study, we identified 7 Dmrt, 62 HMG-box, and 73 TGF-β family members in the zig-zag eel genome.

Uridine diphosphate-glycosyltransferases (UGTs) are responsible for glycosylation by combining various small lipophilic molecules with sugars to produce water-soluble glycosides, which are crucial for the metabolism of plant secondary metabolites and detoxification in insects. This study presents a genome-wide analysis of the UGT gene family in the brown planthopper, Nilaparvata lugens, a destructive insect pest of rice in Asia. Based on the similarity to UGT homologs from other organisms, 20 putative NlUGT genes were identified in N.

Grass carp is an important commercial fish in China that is plagued by various diseases, especially the hemorrhagic disease induced by grass carp reovirus (GCRV). Autophagy, a highly conserved biological process among eukaryotes, is pivotal in maintaining cellular homeostasis and managing various stressors, including viral infections. Uncoordinated (Unc) 51-like kinase 2 (ULK2) is considered an initiator of the autophagic process.

Background: In humans and other mammals, the process of oogenesis initiates asynchronously in specific ovarian regions, leading to the localization of dormant and growing follicles in the cortex and medulla, respectively; however, the current understanding of this process remains insufficient.
Results: Here, we integrate single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) to comprehend spatial-temporal gene expression profiles and explore the spatial organization of ovarian microenvironments during early oogenesis in pigs. Projection of the germ cell clusters at different stages of oogenesis into the spatial atlas unveils a "cortical to medullary (C-M)" distribution of germ cells in the developing porcine ovaries.
