In this work, Pleurotus eryngii protein-polysaccharide conjugates (PE-PPCs) were used as the only stabilizer for the preparation of high internal phase emulsions (HIPEs). PE-PPCs presented spherical particles in solution, and their three-phase contact angle had a strong correlation with pH values, and the angle at pH 10.0 was almost 90°, showing the most balanced hydrophilicity and hydrophobicity.

Overexpression of the leaf color (Lc) gene in Ma bamboo substantially increased the accumulation level of anthocyanin, and improved plant tolerance to cold and drought stresses, probably due to the increased antioxidant capacity. Most bamboos, including Ma bamboo (Dendrocalamus latiflorus Munro), are naturally evergreen and sensitive to cold and drought stresses, while it's nearly impossible to make improvements through conventual breeding due to their long and irregular flowering habit. Moreover, few studies have reported bamboo germplasm innovation through genetic engineering as bamboo genetic transformation remains difficult.

This study aimed to explore the basic structural features of phosphorylated Pleurotus ostreatus polysaccharide (PPOP) and study the protective effect of PPOP on liver injury induced by carbon tetrachloride in male Kunming mice. The phosphorylated polysaccharide was prepared from the natural polysaccharide extracted from Pleurotus ostreatus (POP). The structures of PPOP and POP were characterized by FT-IR, ESEM spectroscopy, and Congo red test.

This work aims to analyze the immunomodulatory effect of pomegranate peel polysaccharides (PPP) on the immunosuppressed mice induced by cyclophosphamide (CTX). All the mice were divided into 6 groups randomly and the immunoprophylaxis mice were administrated with PPP [100, 200, 400 mg/(kg·d)] by gavage for consecutive 28 days. The results showed that PPP can slow down the decline of body weight and increase the immune organ index of the immunosuppressed mice.

The magadiite⁻magnetite (MAG⁻Fe₃O₄) nanocomposite has great potential applications in the field of biomaterials research. It has been used as a novel magnetic sorbent, prepared by co-precipitation method. It has the dual advantage of having the magnetism of Fe₃O₄ and the high adsorption capacity of pure magadiite (MAG).

This proposed work aimed to investigate the chemical characteristic, antioxidant capacities and hepatoprotection effect of pomegranate peel polysaccharides (PPP) on CCl-induced oxidative damage in mice. PPP was identified as the acidic heteropolysaccharides by HPLC methods. In vitro test showed that PPP had excellent reducing power and scavenging effects against free radicals.

In this work, based on response surface methodology (RSM), an optimized method of extracting water-soluble polysaccharide from pomegranate peel (PPP) with pectinase was proposed. Additionally, the chemical composition and the antioxidant activities of the extracted PPP were studied. The effects of three factors of enzymolysis time, ratio of liquid to solid and dosage of enzyme on the PPP yield were investigated.

Background: Sleep apnoea hypopnoea syndrome (SAHS) is characterised by repetitive nocturnal hypoxemia and has a high prevalence among patients with acute myocardial infarction (AMI). But there are few studies on patients with AMI undergoing emergency primary percutaneous coronary intervention (pPCI). In this study, we want to find the prevalence of SAHS among patients with AMI undergoing emergency pPCI and determine whether SAHS would worsen the condition among these people, and especially affect the damage degree of the coronary artery.

Genetic engineering technology has been successfully used in many plant species, but is limited in woody plants, especially in bamboos. Ma bamboo ( Munro) is one of the most important bamboo species in Asia, and its genetic improvement was largely restricted by the lack of an efficient regeneration and transformation method. Here we reported a plantlet regeneration and -mediated transformation protocol by using Ma bamboo young shoots as explants.

Ultrasonic technique was employed to extract polysaccharides from pomegranate peel. The optimal conditions for ultrasonic extraction of pomegranate peel polysaccharide (PPP) were determined by response surface methodology. Box-Behnken design was applied to evaluate the effects of four independent variables (ratio of water to raw material, extraction time, extraction temperature, ultrasonic power) on the yield of PPP.

A study about the ultrasonic extraction, antioxidant capacity and identification of phenolics from Semen Astragali Complanati was undertaken. The optimised extraction condition with an orthogonal experiment design of L9(3(4)) was 50°C, 30min and 15:1 (methanol solution:sample, mL:g). An extraction yield of 40.

In this study, response surface methodology was employed to optimize the extraction process of crude polysaccharides from Pomegranate peel with water. Three independent and main variables, including extraction time (h), extraction temperature (°C) and ratio of water to raw material (ml/g), which were of significance for the yields of polysaccharides were studied and the Box-Behnken design was based on the results of a single-factors test. The experimental data were fitted to a second-order polynomial equation using multiple regression analysis and also examined using the appropriate statistical methods.

Background: Lycium barbarum polysaccharide (LBP), isolated with boiling water from the famous Chinese medicinal herb Lycium barbarum fruits, is one of the most important functional constituents in Lycium barbarum. In this study the effects of LBP on cell proliferation, cell cycle and apoptosis in human cervical carcinoma cells (HeLa cells) were investigated.

Results: LBP could inhibit the proliferation of HeLa cells by changing cell cycle distribution and inducing apoptosis.

Soyasaponins are present in legumes and soybeans are the primary dietary source of saponins. SS-II, the second fraction of soyasaponins, was separated by column chromatographic method with D101A macroporous resin from soybean. In this paper, at the concentration range of 100-400 mg/L, SS-II had obvious cytotoxic effect on Hela cells by MTT assay.

Lycium barbarum polysaccharide (LBP), extracted from Lycium barbarum that is a kind of traditional Chinese herb, is found to have anticancer activity. In this study, the effect of LBP on the proliferation rate, cell cycle distribution and apoptosis in the human hepatoma QGY7703 cell line were investigated. The effects of this compound were also tested on the concentration of calcium in cells.
