TL;DR: Microalgae cultures offer an elegant solution to tertiary and quandary treatments due to the ability of microalgae to use inorganic nitrogen and phosphorus for their growth, therefore, it does not lead to secondary pollution.

TL;DR: In this article, the authors reviewed the current status on biotic indoor air pollution, role of fungi as biological contaminants and their impact on human health in indoor environments, including allergy, infections and toxicity.

TL;DR: Under the same conditions of this study, co-inoculation of PDB and KDB in conjunction with direct application of rock P and K materials (R(P + K)) into the soil increased P andK availability and uptake, and the plant growth (shoot and root growth) of maize plants grown on P and k limited soils.

TL;DR: Investigating the effect of four levels of cadmium in interaction with two analogs of brassinosteroids on the growth, fruit yield and quality of tomato found the metal had a negative impact on the antioxidant system of the resulting fruits.

TL;DR: It is concluded that inoculation with rhizobia and arbuscular mycorrhizal fungi could improve the efficiency in phosphorus use for symbiotic nitrogen fixation especially under phosphorus deficiency.

TL;DR: The results suggested that the P. aeruginosa strain PS1, exhibiting novel plant growth regulating physiological features, can be applied as an eco-friendly and plant growth catalyzing bio-inoculant to ameliorate the performance of greengram in fungicide stressed soils.

TL;DR: Up-to-date information on this mushroom including its taxonomy and health promoting benefits are presented and safety issues concerning the use of this fungus will be discussed.

TL;DR: Four barley and two wheat genotypes were evaluated in south-eastern Russia to identify heat- and drought-tolerant genotypes for future breeding programmes by identifying suitable sowing times for specific genotypes.

TL;DR: It was revealed that chronic exposure to lead produced significant histological and histochemical changes in the liver of the Wistar albino rats.

TL;DR: The results of this study showed that DMBPO is cytotoxic to cancer cells and possesses antioxidant property.

TL;DR: The vegetation type is fundamentally of chamaephytic nature with some phanerophytes, and distinguished into associations where the dominant perennial species give the permanent character of plant cover in each habitat.

TL;DR: The ability of 12 selected PSB and PSF to grow and solubilize tricalcium phosphate in the presence of different concentrations of NaCl was examined and the amount of P i released in general among PSF was found to decrease with increase in NaCl concentration at all the incubation periods.

TL;DR: It is suggested that the pre-administration of P. betle leaf extract exhibited remarkable protective effects against cadmium-induced oxidative hepatic injury in rats.

TL;DR: In this article, a study was initiated to screen the antioxidant activities, tyrosinase inhibitory effects on the fruiting bodies of Pleurotus ferulae extracted with acetone, methanol and hot water.

TL;DR: First report on the mosquito larvicidal activity the combined effect of Aloe vera leaf extract and B. sphaericus against as target species of A. aegypti is provided and it is established that there is a substantial amount of synergist act.

TL;DR: Some potential biotechnological approaches for the conservation and further manipulation of these rare and endangered plant species to enhance their yield and quality traits are described.

TL;DR: Evidence is provided that the polyphenolic extract of I. frutescens is a natural source of antioxidant against oxidative damage.

TL;DR: It is revealed that exposure to gentamicin can induce significant histological alterations in the kidney as well as remarkable blood chemical changes that might indicate marked renal failure.

TL;DR: The findings indicate that the extract of Agaricus blazei Murill can protect the liver against carbon tetrachloride induced oxidative damage in rats and is an efficient hepatoprotective and antioxidant agent against carbon gaelic acid induced liver injury.

TL;DR: It is suggested that gold NPs of 10 nm diameter produce significant lipid peroxidation in rat liver however lungs and heart do not show any oxidative stress.

TL;DR: Using spectrophotometric assays, it is shown that harmine ingestion provoked a severe reduction in protein, glycogen and lipid contents, revealing the potent bioinsecticidal effect of harmine.

TL;DR: This is the first study to report that B. flexus can degrade MCs, and the coexistence of such bacteria with MCs in the same environment can contribute to the self-purification of the ecosystem from such potent toxins.

TL;DR: The RNAi mechanism is reviewed and some of its applications in biomedical research such as treatment for HIV, viral hepatitis and several other diseases are focussed on.

TL;DR: Soil electrical conductivity, organic carbon and soil texture showed significant correlations with species richness and the cover values of some dominant species, suggesting the significant role of soil characteristics in weed community structure and diversity.

TL;DR: Ordination of stands by Detrended Correspondence Analysis (DCA) indicates that the stands of the three habitats are markedly distinguishable and show a clear pattern of segregation on the ordination planes, which indicates variations in the species composition among habitats.

TL;DR: This study represented the first report for the detection of group A rotavirus and B. abortus antigen and antibodies in calf camels in Saudi Arabia and indicates the strong correlation between the camel calf diarrhea and the detections of enterotoxogenic E. coli.

TL;DR: Results showed that ash and moisture contents were significantly higher in camel milk casein of all breeds compared to that of cow milk and the relative migration of αs-, β- and κ-casein of camel casein was slower than those of cow casein.

TL;DR: Results of the percent survival index and microbiological analysis clearly show that Asparagopsis extract incorporated medicated feed had broad therapeutic potential for managing shrimp Vibriosis.

TL;DR: In this article, the authors used date syrup as an economical source of carbohydrates and immobilized Aspergillus niger J4, which was entrapped in calcium alginate pellets, were employed for enhancing the production of citric acid.

TL;DR: The observations of this study show that in many cases T b is already close to the upper lethal limit of around 47° C in these species and therefore allowing their T b to increase as T a increases are not an option, so global warming will have a detrimental impact on a wide range of desert animals.
