Objective: To study preliminarily on the relationship between properties of the mixture composed of Tongsaimai extract and different excipients and pellet molding.
Method: The multivariate regression analysis was used to investigate the correlation of different mixture and pellet molding by measuring the cohesion, liquid-plastic limit of mixture, and the powder properties of pellets. The weighted coefficients of the powder properties were determined by analytic hierarchy process combined with criteria importance through intercriteria correlation.
Result: The results showed that liquid-plastic limit seemed to be a major factor, which had positive correlation with pellet molding, while cohesion had negative correlation with pellet molding in the measured range.
Conclusion: The physical properties of the mixture has marked influence on pellet molding.

Melt-based 3D printing technologies are currently extensively evaluated for research purposes as well as for industrial applications. Classical approaches often require intermediates, which can pose a risk to stability and add additional complexity to the process. The Advanced Melt Drop Deposition (AMDD) technology, is a 3D printing process that combines the principles of melt extrusion with pressure-driven ejection, similar to injection molding.

Article Synopsis
- A clinical trial tested the effectiveness of adding nanogold particles to denture bases made of polymethyl methacrylate (PMMA) against standard acrylic bases, focusing on their impact on bacterial growth.
- Twenty-two male patients with no teeth received either traditional acrylic dentures or those enhanced with nanogold, and microbial growth was measured over time around the implants.
- Results showed that dentures with nanogold significantly reduced bacteria counts (Candida albicans, Escherichia coli, and Streptococcus mutans) at 2, 4, and 6 months compared to traditional dentures, suggesting a promising improvement in oral hygiene.

Anaerobic gut fungi of the phylum Neocallimastigomycota are microbes proficient in valorizing low-cost but difficult-to-breakdown lignocellulosic plant biomass. Characterization of different fungal life stages and how they contribute to biomass breakdown are critical for biotechnological applications, yet we lack foundational knowledge about the transcriptional, metabolic, and enzyme secretion behavior of different life stages of anaerobic gut fungi: zoospores, germlings, immature thalli, and mature zoosporangia. A Miracloth-based technique was developed to enrich cell pellets with zoospores - the free-swimming, flagellated, young life stage of anaerobic gut fungi.

Article Synopsis
- - The study examined how the ctnA gene affects the growth and characteristics of M. purpureus by creating strains that either knocked out or overexpressed the gene, focusing on citrinin production.
- - Findings showed that deleting ctnA led to longer mycelium and less citrinin (22% of the wild-type), while overexpressing it resulted in slower growth and more citrinin (120% of the wild-type).
- - The research highlights a link between citrinin production and the physical structure of the fungus, suggesting methods to enhance metabolite production for industrial use.
