A study conducted by researchers at the Military University of Technology in Warsaw, Poland, explored the use of graphene paper as a carrier for medicinal substances. The researchers incorporated the antibiotics ciprofloxacin, cefazolin, and methicillin into the graphene paper and tested its impact on bacterial strains. The study found that graphene paper with ciprofloxacin had a bactericidal effect on Staphylococcus aureus and Pseudomonas aeruginosa strains, while methicillin and cefazolin acted mainly locally. The research suggests that graphene paper can be used as a carrier for selected medicinal substances. [Extracted from the article]

A recent preprint abstract discusses a cryopreservation strategy for storing myoblasts, which are cells involved in skeletal muscle health, in paper-based scaffolds. The goal of this research is to make it easier for the broader biology community to use three-dimensional tissue-engineered models for studying skeletal muscle pathophysiology and developing therapeutic agents. The researchers developed a protocol using commercially available reagents that allows myoblasts to be cryopreserved in a format that can be easily transferred to users without expertise in skeletal muscle cell culture. The study validates that the cryopreserved myoblasts maintain cell viability, differentiation, and function, and demonstrates successful shipping and use of the tissues by collaborators. The researchers also applied their method to study muscle endogenous repair. This research has not yet undergone peer review. [Extracted from the article]

Researchers from Mustansiriyah University in Baghdad, Iraq have developed a spectrophotometric method and a paper-based microfluidic device for the quantitative determination of Amoxicillin in pure form and pharmaceutical preparations. The detection method involves a coupling reaction of Amoxicillin with diazotized sulfadimidine in an alkaline medium, and the reaction product is measured at a specific wavelength. The paper-based microfluidic device can be used for the semi-quantitative determination of Amoxicillin in pure solution and commercial pharmaceutical products for rapid screening. This research provides a low-cost and portable method for analyzing active pharmaceutical ingredients in the pharmaceutical industry. [Extracted from the article]

A recent study conducted by researchers at Beijing Normal University explores the use of drawing paper as a therapeutic tool in drama counseling. The study focuses on a case study involving a Chinese primary school student who used drawing paper as a stage to act out a drama, allowing for emotional catharsis and expression. The research suggests that this approach could lead to a new therapeutic model in individual mental health counseling. The study also highlights the cultural significance of the drawing in drama counseling model within the Chinese culture.

A recent study conducted by researchers at Shanghai University in China has developed a simple and affordable paper analytical device for on-site detection of lead (Pb). The device utilizes a visual distance-based method to detect Pb by inhibiting the catalytic activity of G-quadruplex/hemin DNAzyme induced by potassium (K+). The device has been optimized to detect Pb concentrations ranging from 0.02 μM to 50 μM, with a lowest detection limit of 1 nM. The researchers believe that this device could be particularly useful for detecting heavy metal ions in resource-limited areas. [Extracted from the article]

A recent study conducted by researchers at the Harbin Institute of Technology in Shenzhen, China, has developed a paper-based microfluidic sensor array for the discrimination of tetracycline antibiotics. The sensor array utilizes lanthanide metal-carbon quantum dots composite ink and inkjet printing technology to create a portable and cost-effective device. The platform successfully differentiated six different tetracycline antibiotics and demonstrated its practicality in real samples. This research has potential applications in disease diagnosis, food safety, and environmental contamination. [Extracted from the article]

Researchers at the University of Karachi in Pakistan have developed a highly stable and sensitive colorimetric sensor using silver nanoparticles (AgNPs) for the detection of omeprazole at trace levels. The sensor combines AgNPs-based paper technology with smartphone technology for real-time analysis of omeprazole. The sensor demonstrated high stability, sensitivity, and versatility, making it suitable for on-site and point-of-care omeprazole detection in various samples. This research provides a promising solution for real-time omeprazole analysis with potential applications beyond pharmaceutical formulations. [Extracted from the article]

A new report discusses research on antimicrobials, specifically focusing on sea buckthorn (Hippophae rhamnoides L.). Sea buckthorn is a species that has shown high productivity and contains bioactive compounds such as polyphenols and carotenoids that have positive effects on the human body. The aim of the study was to investigate the productivity and correlation between the chemical composition and antibacterial effect of four cultivars of sea buckthorn. The research found that the sea buckthorn cultivars tested had different carotenoid contents, ascorbic acid contents, organic acids, total dry matter contents, titratable acidities, and pH values. The antimicrobial activity of sea buckthorn was also evaluated and found to vary depending on the form of the fruit. [Extracted from the article]
