“…69 The peak at 965 cm −1 is due to the −CH bending vibration of poly(ethylene glycol) (PEG). 70 The surface-enhanced Raman spectrum (SERS) at 438 cm −1 is dominated by the −CH stretching of out-of-plane bending of alkanes of polyols, 71 while that at 1967 cm −1 is due to CC stretching, 72 and those at 2449 and 3173 cm −1 are due to the −CH stretching of the carboxylic group of L-ascorbic acid. 73 Besides, the Raman scattering spectrum of β-Cu 2 O NPs is dominated by ring deformation, ring twisting deformation, and ring breathing and wagging (Figure 3).…”

The physicochemical approaches and biological principles in bio-nanotechnology favor specially functionalized nanosized particles. Cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase with a little tenorite (CuO) may be very effective in the development of novel therapeutic approaches against several fatalities including A-549 lung carcinoma cell lines. Consequently, the synthesis of β-Cu2O NPs for the improvement in the therapeutic index and drug delivery application is becoming an effective strategy in conventional anticarcinoma treatment. Hence, surface-enhanced nanosized spherical cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase were successfully prepared using poly(ethylene glycol) (PEG) as an amphiphilic nonionic surfactant and l-ascorbic acid (K3[Cu(Cl5)]@LAA-PEG) reduced to cuprites β-Cu2O NPs via the sonochemical route. Less improved toxicity and better solubility of β-Cu2O NPs compared with Axitinib were a major reason for producing β-Cu2O NPs from K3[Cu(Cl5)]@LAA-PEG (LAA, l-ascorbic acid, PEG, poly(ethylene glycol) (PEG)). These nanoparticle syntheses have been suggested to influence their cytotoxicity, free-radical scavenging analysis, and reactive oxygen species (ROS) using poly(ethylene glycol) (PEG) and l-ascorbic acid (LAA) as coated and grafted materials due to their dose-dependent nature and IC50 calculations. The surface morphology of the formed β-Cu2O NPs has been examined via UV–vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy with energy diffraction scattering spectroscopy (SEM@EDS), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) analysis. X-ray diffraction (XRD) and Brunauer–Emmett–Teller (BET) surface analysis results confirm the presence of pure cuprite with a very little amount of tenorite (CuO) phase, Dynamic light scattering (DLS) confirms the negative ζ-value with stable nature. Docking was performed using PDB of lung carcinomas and others, as rigid receptors, whereas the β-Cu2O NP cluster was treated as a flexible ligand.

“…Bamboo leaf extract has free radical scavenging, antioxidant, anti-inflammatory and antibacterial properties and its main functional components are phenolic acids and flavonoids, which are considered safe functional food additives [ 7 – 9 ]. Additionally, numerous studies have extracted flavonoids and phenolic acids from different structural bamboo parts such as shoots, culms [ 10 ], shoot sheaths [ 11 ], shavings extract [ 12 ] and fruits [ 13 ]. Flavonoids give plants a wide range of colors from light yellow to blue and improve their ability to resist biotic and abiotic stresses.…”

Background Chimonobambusa hejiangensis (C.hejiangensis) is a high-quality bamboo species native to China, known for its shoots that are a popular nutritional food. Three C.hejiangensis cultivars exhibit unique color variation in their shoot sheaths, however, the molecular mechanism behind this color change remains unclear. Methods We investigated flavonoid accumulation in the three bamboo cultivar sheaths using metabolomics and transcriptomics. Results UPLC-MS/MS identified 969 metabolites, with 187, 103, and 132 having differential accumulation in the yellow-sheath (YShe) vs. spot-sheath (SShe)/black-sheath (BShe) and SShe vs. BShe comparison groups. Flavonoids were the major metabolites that determined bamboo sheath color through differential accumulation of metabolites (DAMs) analysis. Additionally, there were 33 significantly differentially expressed flavonoid structural genes involved in the anthocyanin synthesis pathway based on transcriptome data. We conducted a KEGG analysis on DEGs and DAMs, revealing significant enrichment of phenylpropanoid and flavonoid biosynthetic pathways. Using gene co-expression network analysis, we identified nine structural genes and 29 transcription factors strongly linked to anthocyanin biosynthesis. Conclusion We identified a comprehensive regulatory network for flavonoid biosynthesis which should improve our comprehension of the molecular mechanisms responsible for color variation and flavonoid biosynthesis in bamboo sheaths.

“…Similar to other edible mushrooms, strain degeneration is an important limiting factor in the development of V. volvacea . Degenerate strains suffer from slow mycelial growth, delayed mushroom emergence, decreased yield, and weakened resistance, all of which significantly impact the industrialization of edible mushrooms ( Li H. B. et al, 2020 ). Cryopreservation is an effective method to slow down the decline in strain quality by reducing mycelial growth and the occurrence of genetic mutations ( Liu et al, 2018 ).…”

The fungal fruiting body is the organized mycelium. Tissue isolation and mycelium succession are common methods of fungal species purification and rejuvenation in the production of edible mushrooms. However, repeated succession increases strain degeneration. In this study, we examined the effect of repeated tissue isolation from Volvariella volvacea fruitbodies on the occurrence of degeneration. The results showed that less than four times in succession improved production capacity, however, after 12 successions, the traits indicating strain degeneration were apparent. For instance, the density of aerophytic hyphae, hyphal growth rate and hyphal biomass were gradually reduced, while the hyphae branching was increased. Also, other degenerative traits such as prolonged production cycles and decreased biological efficiency became evident. In particular, after 19 successions, the strain degeneration became so severe no fruiting bodies were produces anymore. Meanwhile, with the increase in successions, the antioxidant enzyme activity decreased, reactive oxygen species (ROS) increased, the number of nuclei decreased, and the mitochondrial membrane potential decreased along with morphological changes in the mitochondria. This study showed that repeated tissue isolation increased oxidative damage in the succession strain due to the accumulation of ROS, causing cellular senescence, in turn, degeneration in V. volvacea strain.
