AI Article Synopsis

  • Changes in harvesting methods in the early 1990s led to the Mahanarva fimbriolata becoming the dominant pest in sugarcane plantations, highlighting a need for more research on its reproductive biology.
  • This study provides a detailed description of the male reproductive system and sperm structure of M. fimbriolata using light microscopy, revealing key components like testes, vasa deferentia, and seminal vesicles.
  • The research also investigates the formation of secondary sperm bundles, suggesting that their unique structure may enhance the reproductive success of this cercopid pest.

Article Abstract

Changes in harvesting methods in the early 1990s led to Mahanarva fimbriolata becoming the most prevalent pest in sugarcane plantations. Encouraged by the scarcity of research on the reproductive system and spermatology of Auchenorrhyncha, we provide a detailed description of the male reproductive system and spermatozoa of this cercopid. This will not only aid in taxonomic purposes but also help in understanding the reproductive biology of the species. The male reproductive system, spermatozoa, and sperm bundles of M. fimbriolata were investigated using light microscopy. Our results reveal a reproductive system consisting of a pair of testes, each with 36 follicles, two vasa deferentia, two well-developed seminal vesicles, a single pair of accessory glands, and an ejaculatory duct. Here, we also describe and explore the particularities of the formation of secondary sperm bundles, where cells interestingly bind only to the apical region of the spermatostyle. We also propose some possible benefits of this unusual organization for the reproductive success of the species.

In many plants, the asymmetric division of the zygote sets up the apical-basal body axis. In the cress , the zygote coexpresses regulators of the apical and basal embryo lineages, the transcription factors WOX2 and WRKY2/WOX8, respectively. WRKY2/WOX8 activity promotes nuclear migration, cellular polarity, and mitotic asymmetry of the zygote, which are hallmarks of axis formation in many plant species.

In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature-dependent sex determination (TSD).

Using the PROMOTE Screener to Identify Psychosocial Risk Factors for Prenatal Substance Use.

J Addict Med

November 2024

From the National Institute on Minority Health and Health Disparities, National Institutes of Health, Bethesda, MD (AA); Department of Obstetrics, Gynecology, and Reproductive Medicine, Renaissance School of Medicine, Stony Brook University, Stony Brook, NY (ML, HP); and Department of Psychology, Stony Brook University, Stony Brook, NY (ML, CH, HP).

Introduction: There is an urgent need to improve the identification of psychosocial vulnerabilities in clinical practice (eg, stress, unstable living conditions) and examine their contribution to prenatal substance use, especially for legal substances such as alcohol, tobacco, and recently, cannabis.

Methods: We conducted a retrospective chart review of 1842 patients who completed the PROMOTE screening instrument during their first prenatal visit to outpatient clinics of a New York State health system in 6/2019-11/2020. The PROMOTE includes 18 core items to assess psychosocial vulnerabilities including the NIDA Quick Screen assessing past year substance use.

BACKGROUND Vulvar melanoma during pregnancy is exceptionally rare. Hormonal and immunological changes in pregnancy have raised concerns about the potential for accelerated melanoma progression and poorer maternal outcomes. This case report describes an unusual presentation of vulvar melanoma in a pregnant patient, which rapidly progressed despite previous treatments, but resulted in a favorable fetal outcome.

Diabetes exacerbates periodontitis by overexpressing reactive oxygen species (ROS), which leads to periodontal bone resorption. Consequently, it is imperative to relieve inflammation and promote alveolar bone regeneration comprehensively for the development of diabetic periodontal treatment strategies. Furthermore, an orderly treatment to avoid interference between these two processes can achieve the optimal therapeutic effect.
