AI Article Synopsis

  • Mannosylerythritol-lipids-B (MEL-B) are glycolipids with benefits for skincare, including moisturizing and antimicrobial properties, which might be useful for treating acne-prone skin.
  • A study aimed to evaluate the antimicrobial effect of MEL-B against certain bacteria using a broth macro dilution method, but the results showed that MEL-B did not inhibit the growth of C. acnes and may even support it.
  • While MEL-B is recognized as beneficial for skincare, the findings suggest it should be avoided in formulations for acneic skin due to its lack of antimicrobial effects.

Article Abstract

Mannosylerythritol-lipids-B (MEL-B) are microbial-produced glycolipids with skincare properties, notably moisturizing, antimelanogenic, antimicrobial, and antiaging. Thus, there is a potential use of MEL-B in a formulation for treating acne-prone skin. This study investigated the antimicrobial effect of MEL-B against the Gram-positive bacteria . The broth macro dilution method was used to evaluate the growth of (3-4 CFU/mL), in the absence (positive control) or presence of MEL-B (128, 192, 256, and 512 μg/mL). Additionally, the leakage of genetic materials was used to determine the potential drug-induced membrane disruption of glycolipids. The amount of DNA and RNA release was quantified spectrophotometrically at 260 nm. Macro dilution technique and membrane integrity experiments showed that MEL-B does not have antimicrobial activity against C. acnes. Indeed, MEL-B assisted growth. Ultimately, MEL-B has been reported as a remarkably active compound for skincare formulations; however, preliminarily, it should be avoided for acneic skin.

Background And Objectives: is a common pathogen associated with healthcare-related infections. It is particularly notable for its ability to develop resistance to multiple antibiotics, making treatment challenging. During the COVID-19 pandemic, increased antibiotic use to manage critically ill patients was contributed to the rise of multidrug-resistant .

Article Synopsis
  • The study aimed to assess the quality of frozen semen from manila ducks after cryopreservation using a specific extender with varying concentrations of dimethyl sulfoxide (DMSO).
  • Fresh semen was collected, evaluated, and cryopreserved with DMSO at concentrations of 4%, 6%, 8%, 10%, and 12%, with the effects analyzed through One-Way ANOVA.
  • Results showed that DMSO at 8% and 6% concentrations significantly improved sperm motility and viability both after equilibration and thawing, with DMSO8 being identified as the most effective formulation for maintaining semen quality.

  • The study aimed to compare the antibacterial effects of four types of honey—two medical-grade and two non-medical-grade—against bacteria found in wounds of dogs and cats.
  • Results showed that medical-grade honey was the most effective in killing bacteria like Staphylococcus and Pseudomonas, while non-medical-grade honey had similar effects against some bacteria.
  • The findings suggest that medical-grade honey is best for treating wounds in pets, but more research is needed to fully understand the effectiveness of other honey types for veterinary use.

Gel-Gel Phase Separation in Clustered Poly(ethylene glycol) Hydrogel with Enhanced Hydrophobicity.

ACS Macro Lett

October 2024

Department of Chemistry & Biotechnology, School of Engineering, The University of Tokyo, Tokyo 113-8656, Japan.

Article Synopsis
  • Researchers developed new hydrophobic PEG hydrogels by using a method called gel-gel phase separation (GGPS) to enhance their applications as artificial extracellular matrices.
  • They found that increased elasticity of the gels improves hydrophobicity and cell adhesion, even though PEG gels are usually water-attracting.
  • The study demonstrated that these specially designed oligo-PEG gels showed better structural properties and cell attachment, paving the way for advancements in tissue engineering and regenerative medicine.

In Situ Antimicrobial Properties of Sabinene Hydrate, a Secondary Plant Metabolite.

Molecules

September 2024

Institute of Biosciences, Life Sciences Center, Vilnius University, Saulėtekio Avenue 7, LT-10257 Vilnius, Lithuania.

The objective of this research was to investigate natural products for their potential against pathogenic microorganisms. Sabinene hydrate (SH), a monoterpenoid, is synthesised by numerous different plants as a secondary metabolite. At present, there is a lack of definite investigations regarding the antimicrobial activity of SH itself and its different isomers.
