Identification of the best plant ratios for a polyherbal tea mix to obtain optimum antioxidant, antidiabetic, and β-glucuronidase inhibition activities.

Background: The influence of plant types and their ratios on the effectiveness of polyherbal formulations is a crucial yet underexplored area of research.

Objectives: This study aimed to identify the optimal ratios of Phylanthus debilis (PW), Osbeckia octrandra (HB), and Artrocarpus heterophyllus (WR) leaf powders for a polyherbal tea to achieve the best functional properties.

Material And Methods: A three-level factorial design was used to examine the combined effect of three independent variables (PW, WR, and HB) on antioxidant, antidiabetic, and β-glucuronidase inhibitory activities.

Nutritional intake of sport undergraduates in Sabaragamuwa University of Sri Lanka.

Background: Nutritional intake plays an important role in determining energy availability which is vital to health, wellbeing, and sports performance in an active population. This research assessed the sports undergraduates' nutritional intake compared to the Dietary Guidelines for Americans and nutrition goals provided by WHO.

Methods: This study is a quantitative, cross-sectional descriptive study.

Hydrothermal Synthesis and In Vivo Fluorescent Bioimaging Application of Eu/Gd Co-Doped Fluoroapatite Nanocrystals.

In this study, Eu/Gd co-doped fluoroapatitååe (Eu/Gd:FAP) nanocrystals were synthesized by the hydrothermal method as a fluorescent bioimaging agent. The phase composition, morphology, fluorescence, and biosafety of the resulting samples were characterized. Moreover, the in vivo fluorescent bioimaging application of Eu/Gd:FAP nanocrystals was evaluated in mice with subcutaneously transplanted tumors.

Applications of Nano Hydroxyapatite as Adsorbents: A Review.

Nano hydroxyapatite (Ca(PO)(OH), HAp) has aroused widespread attention as a green and environmentally friendly adsorbent due to its outstanding ability in removing heavy metal ions, radio nuclides, organic pollutants and fluoride ions for wastewater treatment. The hexagonal crystal structure of HAp supports the adsorption mechanisms including ionic exchange reaction, surface complexation, the co-precipitation of new partially soluble phases and physical adsorption such as electrostatic interaction and hydrogen bonding. However, nano HAp has some drawbacks such as agglomeration and a significant pressure drop during filtration when used in powder form.

Electrospun preparation and biological properties in vitro of polyvinyl alcohol/sodium alginate/nano-hydroxyapatite composite fiber membrane.

The composite fiber membrane of polyvinyl alcohol (PVA)/sodium alginate (SA)/nano-hydroxyapatite (nHAP) was fabricated by electrospinning method. In order to prevent the agglomeration and precipitation of nHAP in aqueous spinning solution, nHAP was ultrasonically suspended in aqueous solution using SA (the component of composite membrane) as stabilizer. The effect of nHAP on the morphology and mechanical property of composite fiber membrane was investigated.
