Ganoderma have been regarded as a traditional source of natural bioactive compounds for centuries and have recently been exploited for potential components in the cosmetics industry. Besides Ganoderma polysaccharides and triterpenes, multiple proteins have been found in Ganoderma. With the in-depth study of these proteins, various pharmacological functions of Ganoderma have become important in the discovery and development of new products. In the review, we summarized and discussed the kinds and characteristics of Ganoderma proteins, especially on fungal immunomodulatory proteins (FIPs) which can be potentially developed into cosmeceuticals or nutricosmetics and are a suitable target for production using established biotechnological methods. Furthermore, we discuss their pharmacological activities of the proteins with a focus on their pharmacological functions related to cosmetics, such as antioxidant activity, inhibition of melanin, antibacterial activity, and regulation of inflammatory mediators. Numerous other questions also are addressed before the proteins can be widely accepted and used as cosmetic additives.

Article Synopsis
- Synthetic polysaccharides can be utilized to design new drugs by examining their structure-activity relationships (SAR), particularly in terms of protein stability.
- The study focuses on the glucan GLSWA-1 and its substructures, revealing that compound 2 enhances insulin secretion in a dose-dependent manner while maintaining insulin's thermal stability.
- Molecular dynamics simulations indicate that compound 2 forms a "groove-binding model" with insulin, suggesting its potential as a hypoglycemic agent due to its favorable structural characteristics.
Novel Spectroscopic Studies of the Interaction of Three Different Types of Iron Oxide Nanoparticles with Albumin.
Nanomaterials (Basel)

Research Institute, Medical University of Plovdiv, 4002 Plovdiv, Bulgaria.
In the present work, we studied the interactions of three types of iron oxide nanoparticles (IONPs) with human serum albumin (HSA) by fluorescence and UV-Vis spectroscopy. The determined binding parameters of the reactions and the thermodynamic parameters, including ΔHo, ΔSo, and ΔGo indicated that electrostatic forces play a major role in the interaction of IONPs with HSA. These measurements indicate a fluorescent quenching mechanism based on IONPs-HSA static complex formation.

Herein, we investigate the yield, micro-structures, rheological properties and bioactivities of new Ganoderma leucocontextum polysaccharide (GLP) obtained from Kangding via ultrasound combined mechanical wall-breaking extraction (UBE), and examine the effect of GLP as a structural and functional improver on the physicochemical, sensory, aromatic, water-holding capacity (WHC), textural, rheological, micro-structural and protein structural properties, and bioactivities of set fat-free goat yogurt (set-FGY). Through response surface optimisation, the extracted GLP achieved a maximum yield of 2.18 %, showing good apparent viscosity and elastic behaviour in 3 % aqueous solution as well as good micro-structure and significant anti-oxidant and anti-diabetic activities.

The hepatoprotective effect of the alcoholic extracts of Ganoderma lucidum fermentation products (GFE) was investigated. C57BL/6 mice were pretreated with GFE for 7 days and then subjected to the chronic-binge ethanol feeding model. GFE pretreatment significantly reduced the ethanol-induced elevated serum levels of aspartate aminotransferase (AST) and alanine transaminase (ALT), hepatic steatosis, and increased triglyceride content.
