The total phenolic content and total flavonoid content of leaves and stems of T. berythea have been estimated. An extraction and purification of phenolic mixture compounds from the leaves and stems of this plant have been performed and their antioxidant potential using the DPPH, H2O2 and chelating of ferrous ions tests has been evaluated. Then, their cytotoxicity on the MCF7 breast cancer cell line by the XTT Cell Viability technique has been studied. Our results demonstrated that leaves of T. berythea had higher total phenolic content and total flavonoid content than stems. On the other hand, the six extract from leaves and stems of this plant demonstrated a high antioxidant potential reaches more than 80%. Also, extracts from leaves of T. berythea had the highest inhibitory effect on MCF7 and U937 cell growth than that of stems. This inhibition was more than 60% for all extracts. These results provide new insight into the health functions of leaves and stems and demonstrate that T. berythea extracts can potentially have health benefits.

39728160 2024 12 27 2079-4983 15 12 2024 Nov 27 Journal of functional biomaterials J Funct Biomater Patient Experience and Wound Healing Outcomes Using Different Palatal Protection Methods After Free Gingival Grafts: A Systematic Review. 360 10.3390/jfb15120360 (1) Background: A free gingival graft (FGG) is a common technique used to reconstruct or enhance the area of keratinized mucosa, while a connective tissue graft (CTG) is utilized to boost soft tissue thickness, thereby promoting stability in interproximal marginal bone levels. Most reported complications following FGG procedure are associated with the donor site. In addition to a painful, open wound in the palate, the most frequent complications linked to FGG harvesting include excessive bleeding, postoperative bone exposure, and recurrent herpes lesions. Numerous methods for securing the donor site after a free gingival graft surgery have been documented in research publications. The main objective of this systematic review was to assess various techniques for protecting the palate after graft harvesting and their impact on patient experience, with a focus on pain management. The secondary objective was to evaluate these techniques in relation to donor site wound healing. (2) Methods: The search was performed across four databases: Medline (PubMed Central), Scopus, Web of Science, and Embase, in accordance with PRISMA guidelines and the recommendations set forth in the Cochrane Handbook for Systematic Reviews of Interventions. The initial search took place on 9 October 2023, followed by an update on 28 June 2024. The search utilized the following keywords: ("wound" OR "injury") AND ("graft" OR "free gingival graft" OR "graft harvesting") AND ("healing" OR "recovery") AND "palate". (3) Results: After conducting the follow-up search, a total of 958 papers were identified: 193 from PubMed, 314 from Scopus, 101 from Web of Science, and 350 from Embase. Ultimately, of the 49 papers that remained, 11 were excluded due to not fulfilling the inclusion criteria, leaving 38 full-text papers on free gingival grafts (FGG) for qualitative analysis. (4) Conclusions: Various methods for palatal protection after free gingival grafts (FGG) are described in the literature, stemming from biological, physical, or chemical sources. Most studies in this review examined platelet-rich fibrin and suggested that it provides no benefits for patients' subjective experiences or wound healing outcomes. While photobiomodulation appears to support wound epithelialization, it does not influence pain perception. Alternatives such as propolis, hyaluronic acid, and medicinal plant extracts show potential for palatal protection; however, further research is needed to thoroughly evaluate their effectiveness.

After its accidental introduction to Korea around the 1980s, it quickly became one of the dominant invasive weeds on the Korean peninsula and is now considered a significant threat to the Korean agroecosystem (Park et al., 2020). In June 2013, a leaf blight was first observed on C. glomeratum in Jeju island, Korea. Voucher specimens (n = 12) from several locations throughout Korea were deposited in the Korea University Herbarium (KUS-F). Symptoms appeared as pale-greenish discolorations in indistinct, poorly defined leaf lesions, which progressed into pallid to brownish lesions without definite margins. The leaf spots were rarely observed on stems and bracts. The black conidiomata became visible in the lesions. Conidiomata were pycnidial, epigenous, and rarely hypogenous, scattered, dark brown to rusty brown, globose, embedded in host tissue or partly erumpent, 60 to 130 µm in diameter, with ostioles measuring 20 to 40 µm in diameter, and released cirriform conidial masses. The conidiomatal wall was composed of textura angularis without distinctly differentiated layers, but the outer cells were darker and somewhat thicker walls than the inner cells. Conidiogenous cells were submerged in the conidiomata wall, ampulliform or elongated ampulliform with a distinct neck and hyaline. Conidia were straight to mildly curved, hyaline, 25 to 65 × 1.5 to 2.5 µm, and 2 to 4-septate. Based on the morphological characteristics, the fungus was consistent with Septoria cerastii Roberge ex Desm. (Priest 1997, Verkley et al. 2013). Pure cultures were obtained by collecting conidia from pycnidia on leaf lesions and streaking them onto water agar media. After incubating at 24°C for 48 hours, germinating conidia were transferred to potato dextrose agar (PDA) plates. An isolate was deposited in the Korean Agricultural Culture Collection under Accession No. KACC 410466. To confirm morphological identification, six phylogenetic loci, including the internal transcribed spacer (ITS), 28S rDNA (LSU), β-tubulin (TUB2), translation elongation factor 1-α (EF), actin (ACT), and RNA polymerase II second largest subunit (RPB2), were sequenced (Verkley et al. 2013) and deposited in GenBank (Accession Nos: PQ061282, PQ106848, PQ120988, PQ120980, PQ120993, and PQ120983). Results of the BLASTn search revealed a nucleotide difference with the ex-epitype culture (CBS 102323) of Septoria cerastii in ITS and LSU regions but a 100% match with reference sequences of S. cerastii (KF252834.1 for TUB2, KF253309.1 for EF, KF253666.1 for ACT, and KF252363.1 for RPB2). In a phylogenetic tree reconstructed using the multi-loci sequences, the Korean isolate formed a well-supported group with reference isolates of Septoria cerastii. Pathogenicity was tested by spraying a conidial suspension (2 × 105 conidia/ml) harvested from a four-week-old PDA culture (KACC 410466) onto the leaf surface of three healthy C. glomeratum plants. Three control plants were sprayed with sterile distilled water. All plants were kept in a dark dew chamber at 26 °C for 24 h and then moved to a greenhouse (22 to 24 °C, >70% relative humidity, and a 12-h photoperiod). After a week, symptoms identical to those observed in the field developed on the leaves inoculated with the fungus. No symptoms were observed on control plants. Septoria cerastii was re-isolated from symptomatic lesions of the inoculated plants, and its identity was confirmed by morphology, thus fulfilling Koch's postulates. This pathogen has been recorded on many species of Cerastium worldwide, including the occurrences on C. glomeratum reported in Australia, New Zealand, and Portugal (Priest 1997, Farr & Rossman 2024). To our knowledge, this is the first report of leaf blight on C. glomeratum caused by S. cerastii in Asia as well as in Korea.

However, Denmark stood out as an exception, maintaining steady life expectancy during this period. This raises important questions about the factors that strengthened the Danish healthcare system and society against the pandemic's challenges. The Danish healthcare system serves 5.8 million citizens with free care, advanced digital infrastructure, and comprehensive health registers. Under the auspices of the Danish Society for Patient Safety, insights from Denmark's response to COVID-19 were collected from the onset of the pandemic. This paper builds on these collected experiences, covering crucial areas such as strategies to reduce transmission, digitalization, management of non-COVID diseases, tracking adverse events, workplace well-being, development and use of predictive models, and maintaining public trust. Patient-level data on contacts, contact types, and clinical procedures were obtained from health administrative systems and clinical quality registries. All results were reported as raw counts, with no statistical analyses applied. During COVID-19, Denmark's healthcare system demonstrated resilience by adapting swiftly, achieving a high vaccination rate, shifting to virtual care, enhancing response capacity through real-time adverse event tracking, and supporting healthcare workers through crisis teams minimizing prolonged sick leave. Predictive models accurately forecasted healthcare demands, while public health strategies focused on monitoring public behavior and trust in authorities. A key lesson from Denmark's handling of COVID-19 is that much of the observed resilience stemmed from pre-existing structures that could be reused, further developed, and expanded. This resilience was further enhanced by an unprecedented readiness for change, cross-sectoral and interdisciplinary collaboration, and the removal of typical barriers. These experiences aim to further improve the quality and resilience of healthcare in Denmark and inspire other countries' healthcare systems. Moving forward, acknowledging chronic conflicts as the new normal, coupled with the reminder that "hope is not a strategy", could serve as a pivotal approach. © 2024 Knudsen et al.

In this study, we characterized the sequences of key downstream genes (PaFPPS, PaSQS, PaSQE, PaCAS, PaHYD1, and PaDWF5-1) involved in the biosynthesis of withanolides, marking the first characterization of these genes in P. alkekengi. Our findings revealed highly conserved amino acid sequences in P. alkekengi, with maximum similarity observed with Withania somnifera. Notably, essential domains crucial for enzyme function were preserved in P. alkekengi, indicating conserved enzyme activity. Comparative analysis of secondary structures, 3D topologies, and evolutionary studies supported ancestral homology. Investigations into the differential gene expression of these genes across seven tissues (young leaves, stems, roots, flowers, mature green fruit, breaker fruit, and red ripe fruit) highlighted higher expression levels in P. alkekengi leaves. These gene expression patterns were corroborated by phytochemical analyses using chromatographic techniques. High-Performance Liquid Chromatography (HPLC) confirmed the production of two key withanolides, withanolide A and withanone, in P. alkekengi, with maximum production observed in leaves and flowers. These findings suggest that P. alkekengi holds promise as an alternative to W. somnifera for large-scale industrial production of withanolides, particularly withanolide A. Using P. alkekengi eliminates the need to sacrifice the plant, which is typically required in traditional extraction methods from the roots of W. somnifera. Copyright © 2024.

Current wood nutrient dynamics models are extensions of those developed for leaf litter decomposition. However, tissue structure and dominant decomposers differ between leaf and woody litter, and recent evidence suggests that decomposer stoichiometry, in combination with litter quality, may affect nutrient release. We quantified decomposition and release of C and nutrients from woody litter for two stem sizes of 22 tree species in a P-limited temperate forest near Sydney, Australia, and compared these to estimates from leaf litter literature. Following theory, N and P accumulated during early decomposition, but began to decline earlier than expected based on work in leaves. Woody litter converged on higher C : N (50) and N : P (80) ratios than in leaf litter studies. C : N at which N was released was higher in larger stems (c. 124) than in smaller stems (c. 82), both being higher than in leaf litter. Drawing from the literature, these differences in N and P dynamics may be due to the identity of wood decomposers. C : N of wood decomposers is higher than the mean C : N of leaf litter decomposers, and this difference in stoichiometry may have important flow-on effects for nutrient cycles in forests. © 2024 The Author(s).

Chemical composition, in vitro cytotoxicity and anti-free radical properties of six extracts from Lebanese Trigonella berythea Boiss. | LitMetric
This study represents an original work aimed to recognize the main constitution of Trigonella berythea. The total phenolic content and total flavonoid content of leaves and stems of T. berythea have been estimated. An extraction and purification of phenolic mixture compounds from the leaves and stems of this plant have been performed and their antioxidant potential using the DPPH, H2O2 and chelating of ferrous ions tests has been evaluated. Then, their cytotoxicity on the MCF7 breast cancer cell line by the XTT Cell Viability technique has been studied. Our results demonstrated that leaves of T. berythea had higher total phenolic content and total flavonoid content than stems. On the other hand, the six extract from leaves and stems of this plant demonstrated a high antioxidant potential reaches more than 80%. Also, extracts from leaves of T. berythea had the highest inhibitory effect on MCF7 and U937 cell growth than that of stems. This inhibition was more than 60% for all extracts. These results provide new insight into the health functions of leaves and stems and demonstrate that T. berythea extracts can potentially have health benefits.
