Solvents—purified water (PW, pH 7), 70% and 99% ethanol (70%E and 99%E, pH 6.5), and acidified ethanol (AE, pH 2)—were employed for extraction. When the different pH solutions were applied to the red cabbage extracts, they altered the extract's color, ranging from pink to yellow, influenced by various anthocyanin forms responsive to pH levels. The AE-extracted red cabbage displayed the highest UV and visible light barrier and total phenolic content (TPC). Then, the AE extract was used to formulate the green-based gelatin active films, alongside the 99%E extract, which had similar alcohol content and TPC values. The films averaged 20-21 μm in thickness. Moreover, incorporating both extracts into the gelatin films increased moisture content and water solubility, though the change in water vapor permeability was not significant compared to the neat gelatin film. The gelatin film incorporating AE-extracted red cabbage (GAE) showed higher water solubility than that incorporating the 99%E extract (GE). Both green-based gelatin active films showed differences in appearance color in the third week. The GAE film exhibited greater color stability, attributed to anthocyanin's distinctive chemical structures favoring acidic environments. This gelatin film incorporating red cabbage by AE-extracted holds promise as an eco-friendly active food packaging material.","PeriodicalId":36369,"journal":{"name":"Journal of Current Science and Technology","volume":"58 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141022257","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}

For this purpose, the anti-inflammatory and anti-acne-inducing bacterial activities of Kameng crude ethanol extract, grown in Suphan Buri Province were investigated, with anti-inflammatory properties assessed by the inhibition of protein degradation and proteinase inhibitory assays. Findings indicated the potential of Kameng extracts as anti-inflammatory drugs that reduce protein degradation and proteinase activities. Kameng extract concentrations ranging from 0.4 to 4.0 x 104 ppm inhibited protein degradation and proteinase activity by 14.66%-50.75% and 28.57%-72.08%, respectively. The agar disc diffusion method revealed that Kameng extracts had strong inhibitory effects against S. aureus and C. acnes, with inhibition zone diameters of 31.15±0.47 and 37.28±0.47 mm, respectively. The minimal inhibitory concentration (MIC) of Kameng extract against S. aureus and C. acnes was 5.0 mg/mL and 2.5 mg/mL while minimal bactericidal concentration (MBC) of Kameng extract against S. aureus and C. acnes was 20.0 mg/mL and 10.0 mg/mL, respectively.

The purpose of this study was to assess associations of age and gender with refractive errors of the elderly presenting at a university clinic. Retrospective review of medical records of elderly patients presenting for eye services in 2020-2021. Demographic, ocular disease and refractive data were collected and analyzed. The number of 1,452 patients aged 60 and over with a mean age of 69.6 ± 8.09 years (range 60 to 101 years) were included. The prevalence of myopia, hyperopia, astigmatism, and anisometropia was 22.4%, 36.5%, 22.7%, and 19.4%, respectively. Compared to those aged 80 and above, myopia increased 5.171 times in those 60-69 yrs and 4.930 times among those 70-79 yrs. Men were significantly more likely to have myopia than women (p<0.001). Hyperopia was significantly less prevalent in those aged 70-79 and aged 80 and above compared to those aged 60-69 (p<0.001). Gender was not associated with hyperopia (p=0.066). The prevalence of astigmatism and anisometropia was higher in older subjects. Astigmatism shifted from with-the-rule (WTR) to against-the-rule (ATR) with age. Astigmatism had no gender difference, but anisometropia was more common in women. Most anisometropia was due to refractive error. Rates of myopia and hyperopia decreased with age while astigmatism increased with age.

This research aimed to investigate the impact of ACA on cytotoxicity, anti-proliferation, and antimigration potential in A549 human non-small cell lung cell lines. The investigation utilized MTT assays to assess cell viability and determined the IC50 values of ACA at 24, 48, and 72 hours to be 50.42 µM, 33.22 µM, and 21.66 µM, respectively. These results reveal a concentration- and time-dependent reduction in cell viability following ACA treatment. In addition, anti-proliferation was performed using colony-forming assays, and ACA showed notable efficacy in significantly decreasing colony formation, highlighting its strong impact on cell proliferation and viability. In the final part, ACA had promising inhibitory effects on migration, which varied depending on the dose used in the scratch assay. In conclusion, ACA highlighted cytotoxic and anti-proliferation properties of A549 cell line, supporting its potential role in lung cancer therapy pending further investigation and development.","PeriodicalId":36369,"journal":{"name":"Journal of Current Science and Technology","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141021588","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}

The copper supported on mesoporous carbon/silica composite (Cu/MCS) in this research was developed as a novel adsorbent to remove caffeine from aqueous solutions. The Cu/MCS material was prepared in two steps. The first step was the preparation of a precursor consisting of copper and natural rubber distributed inside a hexagonal mesoporous silica matrix (Cu/NR/HMS). Then, the composite was carbonized at high temperature under inert gas conditions to obtain Cu/MCS material. The amount of Cu loading in the MCS structure was studied. The Cu/MCS composites revealed a high level of copper distribution incorporated into the mesoporous carbon/silica framework as confirmed by Powder X-ray diffraction (XRD) and Scanning Electron Microscope and Energy Dispersive X-ray Spectrometer (SEM-EDS). The Cu/MCS materials possessed a high specific surface area (523–748 m2 g−1), large pore volume (0.80–0.86 cm3 g−1) and mesoporous diameter (3.07-3.30 nm). Fourier Transform Infrared Spectroscopy (FT-IR) and CHN analysis revealed a high amount of carbonaceous species dispersed in the Cu/MCS material. The Cu (0.010)/MCS, with copper loading of 1 mmol/g, revealed good properties for CAF removal when compared to other series of Cu/MCS adsorbents.

Anaerobic germination significantly affected the moisture and carbohydrate contents in germinated riceberry rice (GRR), whereas the contents of crude protein, crude fat, ash and crude fiber were not changed significantly. During anaerobic germination, production of ATP was limited; therefore, the enzyme activity in the seed could be delayed in order to conserve the nutrients. With increasing germination time, gamma-aminobutyric acid (GABA) increased, reaching a maximum percentage of 58.6% in 96-hour GRR but total phenolics and total anthocyanins significantly decreased with a loss percentage of 26.5% and 44.4%, respectively. Enzymatic saccharification using a-amylase and a-glucoamylase significantly increased sugar (total sugar, reducing sugar and glucose) contents in GRR extract, depending on incubation duration of both enzymes. The 0.5 hour-incubation with a-amylase in combination with the 12 hours-incubation with a-glucoamylase was the condition under which the extract contained the highest amount of reducing sugar (22.5 g/L), glucose (11.1 g/L) and total phenolics (22.5 g gallic acid equivalent/L).

This study evaluates the antimicrobial, antioxidant, and cytotoxic activities of Hawaiian-grown Boesenbergia rotunda. Test bacteria included clinical isolates of Gram-positive MRSA and methicillin-susceptible S. aureus (MSSA) as well as Gram-negative Serratia marcescens and Escherichia coli. Five compounds–cardamonin, pinostrobin, pinocembrin, pinostrobin chalcone, and isopanduratin A–were isolated from the ethyl acetate extract of B. rotunda rhizome, and their structures were identified by NMR spectroscopy. These samples exhibited antimicrobial activity against MRSA and MSSA strains, with minimum inhibitory concentration (MIC) values between 128 and 2 µg/mL, with isopanduratin A giving MIC values as low as 2 µg/mL. The antioxidant potential of samples was examined using ferric-reducing antioxidant power (FRAP) assay. At 1 mg/mL of tested samples, FRAP values ranged between 8.74 to 17.76 µM/µg, with pinostrobin chalcone exhibiting the highest FRAP value (17.76 ± 0.65 μM/μg).

Multimodal biometric authentication is a hot emerging area of research. The memory requirements, response times, and adoption/operating costs of conventional multimodal biometric identification methods are all higher than those of single-modal approaches. In this article, we conducted an examination of a framework for multimodal biometric identification systems, which demonstrates a practical implementation of soft computing strategies adaptable to face, finger, and palmprint biometrics. We applied a modified Gabor filter for feature extraction to increase processing speed and reduces the timing. Validation of the proposed system was achieved by the development of a fusion system using principal component analysis as a single matcher classifier. An adaptive fuzzy genetic algorithm was applied for weight optimization which generates verification at a high-rate performance using the fuzzy logic function. Employing fusion in identification mode, the technology was critically examined. The results indicated that the multimodal biometric system outperforms in terms of TPR, FPR, TNR, FNR, Precision, Recall, F-score, and Accuracy, resulting in reduced processing time and memory footprint, and speedier implementation.","PeriodicalId":36369,"journal":{"name":"Journal of Current Science and Technology","volume":"1 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138596940","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}
