Problem statement: Nephrolithiasis or renal stone disease remains a significant health problem in the adult population. Nephrolithiasis is a recurrent disorder prominent in males. It is significant medical and surgical problem because of incidence, recurrence and severe consequences. The present day medical management of nephrolithiasis is either costly or not without side effects. Invasive pro...

the successful aquaculture depends on different criteria, among them, selection of suitable food with required potential is of particular importance. in this study, effects of four diet trial including control diet (without spirulina algae) and three diets containing spirulina algae were investigated on the growth indices and skin color of flower horn (pseudotropheus demasoni). a total number o...

Surface characterization and metal ion adsorption properties of Spirulina sp. and Spirulina maxima were verified by various instrumental techniques. FTIR spectroscopy and potentiometric titration were used for qualitative and quantitative determination of metal ion-binding groups. Comparative FTIR spectra of natural and Cu(II)-treated biomass proved involvement of both phosphoryl and sulfone gr...

This work aimed to evaluate the thermal and photo stability of the antioxidant potential (AP) of the Spirulina platensis biomass. Thermal stability was established at 25ºC, 40ºC and 50ºC for 60 days, in the dark, protected from light. Photo stability was evaluated using UV (15 W, λ = 265 nm) and fluorescent (20 W, 0.16 A, power factor FP > 0.5, 50/60 Hz, 60 lm/w, 1200 lm) light for 90 days in c...

Background: Isolation of methyl gamma linolenate from Spirulina platensis using flash chromatography and its apoptosis inducing effect against human lung carcinoma A549 cell lines. Methods: Gamma linolenic acid is an important omega-6 polyunsaturated fatty acid (PUFA) of medicinal interest was isolated from microalgae Spirulina platensis using flash chromatography system (Isolera system) as its...

The cyanobacterium Arthrospira is among the most well-known food supplements worldwide known as "Spirulina." While it is a widely recognized health-promoting natural product, there are no reports on the molecular diversity of commercially available brands of "Spirulina" supplements and the occurrence of other cyanobacterial and heterotrophic bacterial microorganisms in these products. In this s...

Spirulina platensis trichomes grown in Zarrouks medium having total Na+ concentration as 0.14 M when transferred to fresh Zarrouks medium containing enhanced level of Na+ ions equal to 0.86 M showed 30% more accumulation of Na+ intracellularly as compared to the control. An inhibition of photosystem II activity to almost 66% was observed. Also due to this exposure to high Na+, the room temperat...

The blue-green microalgae Spirulina, used in daily diets of natives in Africa and America, have been found to be a rich natural source of proteins, carotenoids, and other micronutrients. Experimental studies in animal models have demonstrated an inhibitory effect of Spirulina algae on oral carcinogenesis. Studies among preschool children in India have demonstrated Spirulina fusiformis (SF) to b...
