Lectins are non-immunoglobulin proteins that bind diverse sugar structures with a high degree of selectivity. Lectins play crucial role in various biological processes such as cellular signaling, scavenging of glycoproteins from the circulatory system, cell-cell interactions in the immune system, differentiation and protein targeting to cellular compartments, as well as in host defence mechanis...

osseointegration has been the concern of implantology for many years. researchers have used various ceramic coatings for this purpose; however, piezoelectric ceramics (e.g., barium titanate [bto]) are a novel fi eld of interest. in this regard, bto (batio3 , bto) coating was fabricated by electrophoretic deposition on ti6al4v medical alloy, using sol-gel-synthesized nanometer bto powder. struct...

UNLABELLED BACKGROUND Cyrtomium fortumei (J.) Smith is an important Chinese herbal medicine because of its biological functions. However, systematic and comprehensive studies on the phytochemicals from Cyrtomium fortumei (J.) Smith and their bioactivity are limited. RESULTS Using the bioassay-guided technique, the ethyl acetate and n-BuOH extracts of the rhizomes of Cyrtomium fortumei (J.)...

Agaricus bisporus is one of the most consumed culinary mushrooms in the world. The white type of Agaricus bisporus has been demonstrated with various bioactivities beneficial to human health. However, little was known about its brown type. In this study, the anti-cancer and immunoregulatory potential of Agaricus bisporus (brown) polysaccharide were investigated in vitro and in vivo. In vitro, t...

Paris polyphylla Smith var. yunnanensis, has been used in traditional Chinese medicine for its antibiotic and anti-inflammatory properties; in addition it has been used to cure liver cancer in particular. In this current study, β-ecdysterone (1) and three pennogenin steroidal saponins (2-4) were isolated from the EtOH extract of Paris polyphylla var. yunnanensis, and then tested for their antit...

Emerging evidence suggests that autophagic modulators have therapeutic potential. This study aims to identify novel autophagic inducers from traditional Chinese medicinal herbs as potential antitumor agents. Using an image-based screen and bioactivity-guided purification, we identified alisol B 23-acetate, alisol A 24-acetate, and alisol B from the rhizome of Alisma orientale as novel inducers ...

Arbutus unedo, Prunus spinosa, Rosa micrantha and Rosa canina are good sources of phenolic compounds, including anthocyanins. These compounds have potent antioxidant properties, which have been related to anticancer activity. Herein, the in vitro antioxidant and antitumor properties of enriched phenolic extracts (non-anthocyanin phenolic compounds enriched extract- PE and anthocyanins enriched ...

The dimeric Nuphar alkaloids are a structurally unique family of natural products containing an unsymmetrical thiaspirane. These sulfur-containing alkaloids were first isolated from the fresh water plant Nuphar lutea by Achmatowicz in the early 1960s. The most potent member of the Nuphar dimer family (6-hydroxythiobinuphraidine, Figure 1) is a rapid inducer of apoptosis, exhibiting in vivo anti...

Scavenger receptor class B type I (SR-B1) binds pathogen-associated molecular patterns participating in the regulation of the inflammatory reaction but there is no information regarding potential interactions between SR-B1 and the interferon system. Herein, we report that SR-B1 ligands strongly regulate the transcriptional response to interferon α (IFNα) and enhance its antiviral and antitumor ...

The rhizome of Menispermum dauricum DC known as a traditional Chinese medicine, with high content of alkaloids, has been found to possess antitumor activity. In this research, an attempt to correlate fingerprinting with bioactivity was made for quality control of M. dauricum. Firstly, the cytotoxicity of extracts from ten batches of samples against human breast MCF-7 cancer cells was estimated ...
