Amyloid fibrils were isolated by extraction in water from the livers and spleens of four patients who had died of monoclonal, light-chain (AL)-type, systemic amyloidosis and one with reactive systemic, amyloid A protein (AA)-type amyloidosis. Each fibril preparation contained 1-2% by weight of glycosaminoglycan (GAG) which was tightly associated with the fibrils and not just co-isolated from th...

An excessive production of indol in the intestine, manifested by increased elimination of indoxyi sulphate or indican in the urine occurs in a number of diseases. The causation of functional nervous disorders among others has been ascribed more than once to indol poisoning, and it is a fact of every-day laboratory observation that the urine of those suffering from migraine or “the blues” and th...

Impact craters and associated hydrothermal systems are regarded as sites within which life could originateonEarth,andonMars.TheHaughton impactcrater,oneof themostwell preservedcratersonEarth, is abundant inCa-sulphates. Selenite, a transparent form of gypsum, has been colonized by viable cyanobacteria. Basementrocks,whichhavebeenshocked,aremoreabundant inendolithicorganisms,whencomparedwithunsh...

Geotechnical engineers, in many cases face with low strength or high swelling potential of clayey soils. Stabilization methods are used to improve the mechanical properties of this type of soils. Lime and cement are the most popular materials used in chemical stabilization of clayey soils. If sulphate exists in the stabilized clayey soil with lime, or if soil is exposed to sulphates, problems s...

When the concentration of hyaluronic acid was monitored in primary cultures of mouse skin dermal fibroblasts, there was an increase in hyaluronic acid proportional to the increase in cell number during the logarithmic growth phase. The concentration reached the maximum value 2 days before the cells became confluent, and then decreased gradually. Hyaluronic acid added at 1 mg ml-1 during the log...

Macroinvertebrate communities and environmental variables were assessed seasonally for 1 year in a temporary river in South Portugal receiving an effluent with high conductivity, pH, sulphates, nitrates and low oxygen content. The usefulness of the ordination method canonical correspondence analysis (CCA) and the classification method cluster analysis (UPGMA) were examined to evaluate the pertu...

An earlier report from these laboratories described the metabolism of carbon and nitrogen compounds by Penicillium notatum in surface culture (Hockenhull, 1946), and some references were made to the utilization of sulphur by this organism. Further work on the latter aspect seemed desirable, especially as penicillin is a sulphur-containing compound. It is the purpose of the present communication...

The scenario of the present era shows that the environmental impact was high on water resources. Water is the eternal source for living with nature. The contamination of groundwater resources is hike at many areas. In this paper an attempt has been taken to analyze the physical and chemical parameters groundwater in the city of Tiruppur. The city of Tiruppur is famous for textiles. There is an ...
