The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

Zoanthid is a potential natural resource with many biological activities, such as antioxidant, antiviral, antiinflammatory, and cytotoxic activity. Therefore, this study aimed to evaluate the antioxidant activity of 70% ethanol crude extract and dichloromethane fraction from Zoanthus vietnamensis. The total polyphenol content of ethanol and dichloromethane extracts were 19.36 ± 1.37 and 24.95 ± 0.63 mg GAE/g extract, respectively.

In this work, a new sulfated polysaccharide was isolated from green seaweed Caulerpa racemosa harvested at Nha Trang sea. The structure of obtained polysaccharide was determined and its cytotoxic activity was evaluated. The results showed that structure of the polysaccharide has a main chain of (1→4)-β-D-galactopyranose residues and branches are (1→3)-α-L-glucopyranose-2,4-disulfate residues linked to the main chain at C-6 position.

natural fiber for the construction of hybrid bio-composites. In the current research project, a thorough analysis of the use of soy-PF resin for the creation of composites reinforced with jute was conducted. A novel and practical cutlery material was created after the mechanical properties were evaluated and optimized. In order to study the value addition of these newly proposed biocomposite materials as an ecological alternative in terms of natural resources versus synthetic resources, variables such as hardness, cytotoxicity, and degrading qualities of composites were also explored.

Overcoming drug resistance is critical for increasing the survival rate of prostate cancer (PCa). Doc‑ etaxel is the first cytotoxic chemotherapeutical approved for treatment of PCa. However, 99% of PCa patients will develop resistance to docetaxel within 3 years. Understanding how resistance arises is important to increasing PCa survival.

Eribulin or capecitabine monotherapy is the next cytotoxic chemotherapy option for patients with metastatic or recurrent breast cancer who have previously received an anthracycline or a taxane. However, it is unclear what factors can guide the selection of eribulin or capecitabine in this setting, and prognostic factors are needed to guide appropriate treatment selection.

In the present study, we have follwed the hydrothermal path for the synthesis of gold nanoparticles (Au NPs) from the biomaterial Elaeocarpus ganitrus seeds extract, which is a rapid, eco-friendly, non-chemical way. The prepared NPs were thoroughly analysed by powder x-ray diffraction and high resolution transmission electron microscopy studies and were also tested for anticancer studies.
