This study is the first report on antioxidant activities and chemical composition of S. cambodianum Baill. ethanolic leaf extract. The results showed that ethanolic extract had potent in vitro antioxidant activities in DPPH, ABTS•+ assays (the low concentrations of IC50 were 19.51 ± 0.78 μg/mL and 4.89 ± 0.07 μg/mL, respectively), and in RP, TAC methods (the Abs0.5 were 20.80 ± 0.26 μg/mL and 36.15 ± 1.03 μg/mL).

In this study, we evaluated and compared the effectiveness of four different protocols (D, MJ, MA, and S) for separating MPs from water of different types (brackish, marine, and river). Known combinations of MP particles (polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS) and polyvinyl chloride (PVC) with size ranging between 150 μm and 700 μm were spiked into water samples. Our results showed that the average recovery effectiveness of microplastics using four studied methods ranged from 53% to 86%.

Resistance to pathogenic bacteria may lead to serious health problems. Scientists found that discovering novel antimicrobial compounds is possible by exploring rarely investigated environments. Therefore, this work focused on isolating and identifying some fungal strains collected from the Co To sea. We tested whether such strains can produce compounds with vital activities, including antibacterial and antifungal. The antimicrobial activity of the marine fungi crude extracts was performed by the Bioassay method in a 96-well tray.

This paper focuses on optimizing the chromatographic instrumental operating parameters and the solid phase extraction conditions using HLB cartridges. Results from the method validation showed that the method has sub ng/L LOQs (0.10-0.60 ng/L), quantitative recoveries at the concentrations near the LOQs (74.4-122.8%) and high repeatability with acceptable %RSD (15.6-38.3%).

The present study focuses on the preparation of silver/copper bimetallic hybrid nanoparticles by green method from precursor solutions of silver nitrate & copper nitrate and the locally available citrus fruit (lemon) peel extract which behaves as the stabilizing and reducing agent. Initially, the formation of hybrid nanoparticles was noticed in the reaction mixture by colour change.

Photocatalytic degradation proficiency was studied for bromothymol blue dye. Phytochemicals-coated Nickel Oxide nanoparticles demonstrated antibacterial properties against bacteria (gram negative strain of E. coli, Pseudomonas spp. and gram positive strain of Bacillus spp.) by showing highest zone of inhibition (19 mm, 22 mm, 15 mm).the antioxidant activity of the synthesized nanoparticles were also examined and the result show that the fabricated nanoparticles exhibited significant radical scavenging activity.

To study analgesic effects of basil extracts (Ocimum basilicum L.) on mice. Subjects and methods: The experiments were conducted according to heat stimulation (hot plate) and needle slide methods. In each experiment, mice were divided into 4 groups of 10 each, in which the negative control group was given distilled water, the positive one took the control drug, and the others were treated with basil extracts at the doses of 2.4 and 7.2 g/kg/day for 7 consecutive days.

Delay is one of the serious problems in the construction industry, particularly in high-rise building construction projects in Thailand. Therefore, this research aims to investigate the major resource supply causes and effects of delay problems in high-rise building construction projects in Thailand. The study employs both quantitative and qualitative study with concurrent mixed method design. Thirty-three resource supply causes and nine effects extracted from the literature review were used as the basis for further analysis.

Patterns in expression data conserved across multiple independent disease studies are likely to represent important molecular events underlying the disease. We present the INSPIRE method to infer modules of co-expressed genes and the dependencies among the modules from multiple expression datasets that may contain different sets of genes.

This article examines the relation of integrated curriculum with implementation of modern teaching methods through the supply chain strategy in education. The research method in this article is analytical-deductive. Considering the fact that in order to extract the dimensions of integrated curriculum, its analysis is done in terms of effective factors in the integration of the curriculum, the research method is an analytical type, and considering that the relation between the integrated curriculum and the application of modern teaching methods is examined, it is deductive.
