This study aimed to develop patches containing quercetin-loaded microcapsules and to evaluate their in vitro and in vivo safety and efficacy in preclinical surveys. A set of in vitro experiments evidenced the virucidal activity of quercetin against the HSV-1-KOS (sensitive to acyclovir) and HSV-1-AR (resistant to acyclovir) strains, with improved outcomes upon the first. The patches presented a homogeneous aspect, were easily handled, had a suitable bioadhesion, and possessed mechanical properties of soft and weak material, besides a pH compatible with human skin.

Article Synopsis
  • Recent research utilizing rolling circle amplification (RCA) and high-throughput sequencing (HTS) has advanced our understanding of bovine papillomavirus (BPV) types associated with lesions in bulls.
  • This study successfully sequenced the genomes of BPV types from esophageal lesions in a bull, revealing the presence of both BPV2 and BPV4—indicating a mixed viral infection in the carcinoma in situ.

Deoxynivalenol (DON) is associated with reproductive toxicity in animals. The frequent contamination of cereal-based foods with DON and the high intake of these by children raises particular concern about the susceptibility of this subpopulation to adverse effects from this mycotoxin. However, age-related differences in the in vivo reproductive toxicity of DON have not been evaluated.

The mycotoxin deoxynivalenol (DON) is frequently present in cereals at low levels, resulting in its occurrence in food and feed. DON has been proven to alter the immune response and induce inflammation in all species, with pigs exhibiting heightened sensitivity and exposure. However, no study has yet evaluated the effects of exposure to DON at the recommended levels in pig feed.

Article Synopsis
  • Resolvin D5 (RvD5) is a lipid mediator known for its anti-inflammatory properties and its ability to increase reactive oxygen species (ROS) during bacterial infections, which can be harmful.
  • In a study involving female hairless mice, RvD5 was administered before UVB exposure, leading to reduced skin swelling and oxidative stress by enhancing antioxidants and decreasing harmful oxidants.
  • The treatment also lowered the levels of inflammatory markers and cell counts, which ultimately resulted in less collagen degradation and skin damage from UVB exposure, suggesting that RvD5 could be a potential treatment for UVB-related skin issues.
