There is merit in investigating novel therapeutic molecules that hit vital targets during the viral infection cycle disrupting the interaction between SARS-CoV-2's spike glycoprotein and the host's angiotensin converting enzyme 2 (ACE2) receptor, potentially offering new avenues for treatment. Accordingly, lipid-based vesicular systems like liposomes or niosomes are frequently utilized to overcome these hurdles. Thus, chemically synthesized compounds were encapsulated within PEGylated bilosomes (PBs) to improve their solubility and intestinal permeability, thereby enhancing their anti-SARS-CoV-2 effectiveness.

  • Preterm infants often experience feeding intolerance due to their immature digestive systems, which can lead to increased risks of complications.
  • A study was conducted to evaluate the effects of oral bovine lactoferrin (LF) supplementation on feeding intolerance and intestinal health in these infants, using a randomized double-blind design with 60 preterm neonates.
  • Results showed that infants receiving lactoferrin achieved full feeding sooner (9 days vs. 15 days) and had lower serum zonulin levels, indicating improved intestinal permeability and feeding tolerance compared to the control group.
