Matrix metalloproteinases (MMPs) are endopeptidases that take significant roles in extracellular matrix degradation and therefore linked to several complications such as metastasis of cancer progression, oxidative stress, and hepatic fibrosis. Hizikia fusiformis, a brown algae, was reported to possess bioactivities, including but not limited to, antiviral, antimicrobial, and anti-inflammatory p...

the alginate was extracted with six different methods from iran south seacoast algae, sargassum sp, and the percentage yield of alginate was determined. we divided our methods to two groups including acidic extraction and non-acidic. in acidic methods, hcl and h 2 so 4 were used as a detergent in extraction process and cacl 2 was exerted in non-acidic treatments. all treatments compared with ea...

In this study, we designed a method to manufacture elevated fermented green tea by using Monascus pilosus, which is known as a functional microbe, and observe its antioxidant abilities and quality characteristics. The water-soluble substance (WSS) content of the fermented tea by M. pilosus (FTM) was lower than that of the non-fermented tea (NFT), although the alcohol-insoluble substance (AIS) c...

Three different fucoidan fractions were isolated and purified from the brown alga, Sargassum mcclurei. The SmF1 and SmF2 fucoidans are sulfated heteropolysaccharides that contain fucose, galactose, mannose, xylose and glucose. The SmF3 fucoidan is highly sulfated (35%) galactofucan, and the main chain of the polysaccharide contains a →3)-α-L-Fucp(2,4SO₃⁻)-(1→3)-α-L-Fucp(2,4SO₃⁻)-(1→ motif with ...

ter, Genetic markers, Electrophoresis. Nine cultivars representing four genotype classes involving two genes ra and rb which are implicated in the smooth-wrinkled character of seeds and in the simple-compound character of starch granules, have been investigated through storage protein electrophoretic patterns. Proteins were alternatively extracted from flours and from protein bodies which were ...

BACKGROUND We have previously reported several lignin-like activities of the alkaline extract of the leaves of Sasa senanensis Rehder (SE), such as anti-HIV and radical scavenging activity. As an extension, possible SE protection of cells from ultraviolet (UV)-induced injury (referred to "anti-UV activity") was investigated. MATERIALS AND METHODS HSC-2, human oral squamous cell carcinoma cell...

The structural modifications and immunochemical activities of several Streptococcus pneumoniae type 19A polysaccharide (PS) preparations have been studied by sugar compositional analysis and immunodiffusion. The 19A PS preparations Lab-A-1 and Lab-A-3 and one PS isolated from 19A strain OB contained fucose (Fuc) and galactose (Gal) in addition to rhamnose (Rha) and glucose (Glc). In contrast, 1...

In traditional medicine, extracts of polysaccharide-containing plants are widely employed for the treatment of cutaneus wounds. The brittle star, as one of marine organisms, encompasses bioactive compounds, which confer the healing potency of damaged arms. The aim of the present study is to investigate the effects of extracted polysaccharide from the Persian Gulf brittle star )Ophiocoma erinace...

deleanu, frei, and hilton have developed the notion of generalized adams completion in a categorical context. in this paper, we have obtained the postnikov-like approximation of a module, with the help of a suitable set of morphisms.

The production of volatile species in torrefaction cellulose, hemicellulose and lignin extracted from woody agricultural biomass was quantified as a function temperature. novel coupling TGA to GC/MS through heated storage loop system allowed sampling released at 11 different temperatures single experiment between 200 300 °C, 3 °C.min?1. results showed that the use fractions obtained samples led...
