Familial pancreatic cancer (FPC) represents a significant yet underexplored area in pancreatic cancer research. Basic research efforts are notably limited, and when present, they are predominantly centered on the and mutations due to the scarcity of other genetic variants associated with FPC, leading to a limited understanding of the broader genetic landscape of FPC. This review examines the current state of FPC research, focusing on the molecular mechanisms driving pancreatic ductal adenocarcinoma (PDAC) progression.

Due to the development of magnetic resonance (MR) imaging processing technology, image-based identification of endolymphatic hydrops (EH) has played an important role in understanding inner ear illnesses, such as Meniere's disease or fluctuating sensorineural hearing loss. We segmented the inner ear, consisting of the cochlea, vestibule, and semicircular canals, using a 3D-based deep neural network model for accurate and automated EH volume ratio calculations. We built a dataset of MR cisternography (MRC) and HYDROPS-Mi2 stacks labeled with the segmentation of the perilymph fluid space and endolymph fluid space of the inner ear to devise a 3D segmentation deep neural network model.

Article Synopsis
  • Several drugs can harm cochlear hair cells, leading to hearing loss, and while some treatments have shown promise in animal models, they often fail to translate effectively to humans due to complex cellular damage mechanisms.
  • The study tested various combinations of compounds aimed at different cellular damage processes in hair cells affected by gentamicin, a drug known to cause damage, to find the most protective combinations.
  • Results demonstrated that combinations of two to four protective compounds improved hair cell survival, with the most effective combination including an antioxidant, an apoptosis inhibitor, an autophagy inhibitor, and a protective growth factor, while using too many compounds decreased the protective effect.

  • Osteoporosis (OP) is a growing health issue linked to aging, and there's increasing interest in using herbal medicines (HMs) alongside bisphosphonates (BPs), the standard OP treatment, to enhance bone mineral density (BMD).
  • A systematic review analyzed 43 randomized controlled trials (RCTs) involving about 4,470 participants to compare the effects of HMs with BPs against BPs alone on BMD.
  • Results indicated that combining HMs and BPs significantly improved BMD more than BPs alone, but the findings are tempered by high variability among the studies and low confidence in the evidence, suggesting more rigorous research is needed.
