Some protein pharmaceuticals from Chinese medicine have been developed to treat cardiovascular diseases, genetic diseases, and cancer. Bioactive proteins with various pharmacological properties have been successfully isolated from animals such as Hirudo medicinalis (medicinal leech), Eisenia fetida (earthworm), and Mesobuthus martensii (Chinese scorpion), and from herbal medicines derived from ...

A method for estimating the nucleotide diversity from AFLP data is developed by using the relationship between the number of nucleotide changes and the proportion of shared bands. The estimation equation is based on the assumption that GC-content is 0.5. Computer simulations, however, show that this method gives a reasonably accurate estimate even when GC-content deviates from 0.5, as long as t...

A soluble viscous protein was purified from yam (Dioscorea opposita Thunb.) tuber mucilage tororo by chromatographic steps, and its functional properties were estimated. The purified dioscorin having the molecular weight of about 200 kDa exhibited high scavenging activities against hydroxyl radicals (IC50 = 195.1 microg/ml) and superoxide anion radicals (IC50 = 92.7 microg/ml). Moreover, it sho...

Plant pathogens have evolved many dispersal mechanisms, using biotic or abiotic vectors or a combination of the two. Rain splash dispersal is known from a variety of fungi, and can be an efficient driver of crop epidemics, with infectious strains propagating rapidly among often genetically homogenous neighboring plants. Splashing is nevertheless a local dispersal process and spores taking the d...

Self-rising starch is a development product of self-rising flour. This minimizes the process, especially in salt and leavening agent weighing stage, so that it reduces time serving process. flour generally made wheat Currently, due to some medical considerations, many people cannot consume this product. Based on research results, gluten compound or triggers for type-1 diabetes. fact has caused ...

Seisyu Sakai (酒 井 清 周) (From the Medical Clinic of Prof. T. Kurokawa, Tohoku University, Sendai) (Received for publication, April 28, 1952) Among many ways of treatment for gastric and duodenal ulcer one which has been adopted by physicians, native and foreign, is to protect the wound surface of ulcer from various stimulants, chemical or physical, by which cure is hastened. Mucin has been used ...

A fast and effective UHPLC/QTOF‐MS method using a simple methanol extraction has been developed to determine the structural characteristics of steroidal saponins from dried rhizomes of two Dioscorea species (D. villosa L. and D. cayenensis Lam.) and dietary supplements. The saponins were identified or tentatively characterized from their retention times and mass spectra and the fragmentation pa...

THE TITLE COMPOUND [SYSTEMATIC NAME: (R)-2-trichloro-methyl-3a,3b,7a,8a-tetra-hydro-5H-pyrano[2',3':4,5]furano[2,3-d][1,3]dioxol-5-one], C(9)H(7)Cl(3)O(5), a triyclic system that contains a central α-d-furan-ose ring cis-fused with a dioxolane ring as well as a δ-lactone ring, exhibits a twisted conformation. The CCl(3) group has an axial orientation. The furan-ose ring approximates an envelope...

In this study, dioscin was isolated from Dioscoreae Rhizoma (DR), which is the rhizome of Dioscorea batatas D(ECNE). that inhabits broad areas of Korea and Japan. To determine whether dioscin induced growth hormone (GH) release, we evaluated its induction effects on GH release both in vitro and in vivo. The 70% methanol extract of DR, and its n-hexane and n-BuOH fractions, induced rat GH (rGH) ...
