Anticoagulant properties of marine algae have been extensively studied for the last 60 years. Sulphated polysaccharides (SPS) of three major divisions of marine algae, viz. Rhodophyta, Phaeophyta and Chlorophyta are reported to have such properties. Some of the active components have been chemically well characterized. Sulphated galactans and fucoidan sulphates from red and brown algae, respect...

This study was designed keeping in view the negative and harmful effects of high levels of Sulphates and Chlorides present in drinking water sources after investigating Sulphate and Chloride contents. Sadiqabad, Rahim Yar Khan, Khanpur and Liaqatpur cities of district RYK, Punjab, Pakistan were investigated for the Sulphate and Chloride levels in different drinking water sources.53 and 23 perce...

Primary alkanesulphonates were shown to serve as non-metabolizable (gratuitous) inducers of the P2 primary alkylsulphohydrolase enzyme in resting cell suspensions of Pseudomonas C12B. The effects of increasing concentrations of inducer on the production of enzyme were complex and suggestive of a multiphasic phenomenon. However, it was possible to determine Kinducer constants (analogous to Km or...

The sources and mechanisms of soluble salt uptake by porous limestone and the associated degradation patterns were investigated for the life-sized 15th century "entombment of Christ" sculpture group located in Pont-à-Mousson, France, using a multi-isotope approach on sulphates (δ(34)S and δ(18)O) and nitrates (δ(15)N and δ(18)O). The sculpture group, near the border of the Moselle River, is wit...

The recognition that keratan and chondroitin sulphates are based on the same polylactose backbone simplifies the study of heteroduplex formation between them, suggests insights into structure-function relationships in tissues, and permits new definitions of the linkage regions.

This study aims at determining the effect of the cement composition and mortar age on the optimum content of sulphates using maximization of compressive strength as a criterion. Extensive experimentation has been performed to achieve this purpose by utilizing four cement types and measuring the strength at ages ranging from 2 days up to 63 months. Strength is correlated with the ratio of sulpha...

velocities in the forward and reverse directions was 54.5: 1 , somewhat lower than that previously reported (McQuate & Utter, 1959). Product-inhibition experiments with a non-saturating concentration of the constant substrate showed that in every case competitive inhibition occurs. This is consistent with a rapidequilibrium random Bi Bi mechanism for the reverse reaction, a similar mechanism to...
