To reduce the risks associated with cytokine storms, alternative approaches are needed. Traditional Thai herbal extracts are recognized for their potential as safe and effective anti-inflammatory agents against various diseases. Hence, this study aims to examine the anti-inflammatory effects of ethanolic extracts from Terminalia chebula, Terminalia bellirica, Phyllanthus emblica, and Andrographis paniculata in reducing inflammation in the A549 alveolar basal epithelial cell lines. We conducted a comparative analysis of the anti-inflammation efficacy of four extracts in reducing the COX-2 upregulation induced by TNF-α stimulation in A549 cells. Among them, T. bellirica exhibited the highest effectiveness in reducing COX-2 levels to 0.38-fold. Furthermore, we validated the anti-inflammation properties of T. bellirica in diminishing inflammation-induced SARS-CoV-2 nucleocapsid. Lentivirus transduction expressing SARS-CoV-2 nucleocapsid demonstrated a dose-dependent increase in the expression of pro-inflammatory cytokines and mediators including TNF-α, IL-8, CXCL-10, and COX-2. Interestingly, treatment with sublethal doses of T. bellirica (30 and 60 μg/mL) led to a significant reduction in COX-2 expression by 30% and 70%, TNF-α by 46% and 75%, IL-8 by 39% and 48%, and CXCL-10 by 46% and 80%, respectively. These findings confirm the potent anti-inflammatory effects of T. bellirica, highlighting its potential as a novel treatment for alleviating the severity of cytokine storms in SARS-CoV-2 and related diseases.","PeriodicalId":132692,"journal":{"name":"Natural and Life Sciences Communications","volume":"107 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140725034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rice landraces are genetically diverse, but with a variation that can be well structured, not random. This review examines the population structure and functional diversity revealed in the rice germplasm acquired from farmers in recent decades. Sizable areas of local varieties are found in parts of Asia with distinctive agroecological environment and cultural heritage. A tally of variety names provides a first approximation of diversity, a frequency distribution of the varieties describes a basic structure of diversity in an agroecosystem. Genetic variation is detectable by microsatellites analysis or expressed in specific functional traits, at various organizational levels of the population, even among those exhibiting uniform appearances. The population dynamics of genetically diverse landraces perpetuated by many farmers are shaped by variations in the bio-physical environment and management practices, but those relying on one or two farmers for their maintenance face a risk of extinction. Diversity in widely grown varieties may either be within the farmer’s seed cache, or among populations of the same variety maintained by different farmers. Local rice varieties or landraces continue to play a crucial role in rice farming, the economic value of some is enhanced by their unique grain quality features. Genetically diverse rice landraces that either contribute towards meeting the household’s rice requirement or those that have become commercially successful, also provide an important service in the in situ conservation of germplasm.","PeriodicalId":132692,"journal":{"name":"Natural and Life Sciences Communications","volume":"57 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140723382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also explored the feasibility of using CVM as an alternative to hand-wrist radiographs among Thai children and adolescents. The samples comprised 95 males and 67 females from Thailand, aged 7–17 years. A total of 162 hand-wrist radiographs and lateral cephalometric radiographs were included. Two experienced oral radiologists independently assessed SM (using Fishman’s method) and CVM (using Baccetti’s method); a third referee observer resolved any discrepancies. The correlation and agreement between the methods were evaluated. The results found a substantial agreement (weighted kappa = 0.594) between SM and CVM. The interobserver discrepancy in categorizing SM stages was mostly found at stage 5, while the most common discrepancy for CVM was at stage 6. A significant positive correlation (Spearman’s correlation coefficient = 0.677, P < 0.001) indicated a moderate to strong association between SM and CVM. The substantial agreement and moderate to strong correlation between CVM and SM highlighted the feasibility of using CVM to assess skeletal growth. However, to ensure reliability, it was necessary to precisely evaluate the appearance of the capping of the epiphyseal plate for SM and the distinction between a rectangular and square cervical spine shape at C3 and C4 for CVM differentiation.

Firstly, extraction procedures using solvent fractionation with various polarity: hexane, ethyl acetate and 95% (v/v) ethanol. The physicochemical properties of B-SE were investigated in terms of partition coefficient (LogP), solubility and pH-stability. To optimize the transethosomes formulation, the compositions were varied in sorts of percent cosurfactant, types of cosurfactant, extract concentration, percent total surfactant and types of particle ingredients (phospholipid or cholesterol). The significant factors influencing physical characteristics of the transethosomes were statistically identified using the 25-1 fractional factorial design. Particle size, polydispersity index (PDI), percent entrapment efficiency (%EE) and ultrastructural morphology of the optimized formulation was then characterized. As a marker of B-SE, ellagic acid (EA) was identified by HPLC at a retention time of 32.506 ± 0.16 min. The LogP of B-SE was 0.17. B-SE was practically insoluble in water but freely soluble in propylene glycol and ethanol. The pH condition that stabilized the extract was pH-5. The optimized formulation, consisted of phospholipid, propylene glycol, TWEEN 20, SPAN 80 and 2.5 mg/ml of B-SE presenting particle sizes of 79.72 ± 2.42 nm, PDI of 0.26±0.02 and %EE of 83.10±0.03% along with a spherical particle shape. To conclude, the optimized transethosomes loaded with B-SE fabricated by phospholipid and propylene glycol has desirable attributes for further developing into an anti-acne cosmeceutical.

The effect of extraction parameters was evaluated using response surface methodology (RSM) with Box-Behnken design. The optimum condition for extraction of bioactive compounds from Napier grass was selected through RSM as 10 mL of ethanol (47.68% v/v) and 50 min of extraction time with ultrasound assisted process (100% amplitude and 20 kHz). The extract from 50 days old grass showed excellent antioxidant properties (68.4 μm Fe (II)/g, 5.1 mg AAE/g, 56.7% of DPPH activity), higher phenolic (8.5 mg GAE/g), flavonoid (3.9 mg QE/g) and protein content (14.9% w/w) which also good antimicrobial and antimutagenic activity.
