Cerebral microbleeds (CMBs) are small, hypointense hemosiderin deposits in the brain measuring 2-10 mm in diameter. As one of the important biomarkers of small vessel disease, they have been associated with various neurodegenerative and cerebrovascular diseases. Hence, automated detection, and subsequent extraction of clinically useful metrics (e.

Catharanthus roseus leaves have been traditionally described to possess potent antidiabetic activity and some leaf-specific alkaloids, including vindoline, have been studied for their antidiabetic potential. The aim of the present study was to validate the antidiabetic property of the plant with special reference to vindoline. An Ayurveda-based method was used to prepare the Swaras [leaf juice extract (LJE)] of three familial C.

Background And Objective: As most Prostate Imaging Reporting and Data System (PI-RADS) 5 lesions on MRI harbor Gleason grade (GG) group ≥2 disease on biopsy, optimal management of patients with imaging-biopsy discordance remains unclear. To estimate grade misclassification, we evaluated the incidence of Gleason upgrading among patients with GG1 disease in the setting of a PI-RADS 5 lesion.

Methods: We conducted a single-institution retrospective analysis to identify patients with GG1 prostate cancer on fusion biopsy with MRI demonstrating ≥1 PI-RADS 5 lesion.

Induction of parthenogenesis (embryo formation from unfertilized egg cells) by embryogenic transcription factors is associated with twin formation at high frequencies, and involves two distinct mechanisms. Synthetic apomixis has been achieved through the induction of parthenogenesis by ectopic expression of the Baby Boom family of transcription factors. An associated phenomenon from this process is the formation of polyembryony including twin progeny at high frequencies, but the underlying mechanisms have not been explored.

Article Synopsis
  • In rice, the transcription factor BABY BOOM 1 (OsBBM1) is crucial for activating the embryo development process right after fertilization, allowing for the formation of embryos without fertilization (parthenogenesis).
  • Researchers found that another transcription factor, DWARF TILLER1 (OsDWT1/OsWOX9A), when expressed alongside OsBBM1 in egg cells, significantly boosts the chances of embryo formation—up to 91% parthenogenesis compared to just OsBBM1 alone.
  • These findings highlight that the combined action of paternal genes is key to initiating embryo development, which can be applied to improve the production of haploid plants and hybrid seeds in agriculture.
