Cyanobacterial bloom, also called blue-green algae, all over the world is generating great concern due to effect of temperature resulting from global warming. Microcystis aeruginosa well known be major causative agent algal bloom. However, there a need for more critical detection relationship between and growth rate Microcystic aeruginosa. In present study, we cultivated batch culture (Toxic No...

Nectins are Ca2+-independent immunoglobulin-like cell-cell-adhesion molecules consisting of four members. Nectins homophilically and heterophilically trans-interact to form a variety of cell-cell junctions, including cadherin-based adherens junctions in epithelial cells and fibroblasts in culture, synaptic junctions in neurons, and Sertoli cell-spermatid junctions in the testis, in cooperation ...

background and objectives : halophilic bacteria produce a variety of pigments, which function as immune modulators and have prophylactic action against cancers. in this study, colorful halophilic bacteria were isolated from solar salt lake and their pigments was extracted in optimal environmental conditions and compared with the pigments of halorubrum sodomense atcc 33755. materials and methods...

A scanty but varied ensemble of finds challenges the idea that Neandertal material culture was essentially static and did not include symbolic items. In this study we report on a fragmentary Miocene-Pliocene fossil marine shell, Aspamarginata, discovered in a Discoid Mousterian layer of the Fumane Cave, northern Italy, dated to at least 47.6-45.0 Cal ky BP. The shell was collected by Neandertal...

background bacillus thuringiensis is the most successful biological control agent used in agriculture, forestry and mosquito control. however, the insecticidal activity of the b. thuringiensis formulation is not very stable and rapidly loses its biological activity under field conditions, due to the ultraviolet radiation in sunlight. melanin is known to absorb radiation therefore photo protecti...

In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...

background and objective: pigment production by microorganisms is important due to more rapid growth, higher efficiency, easier extraction, and antimicrobial effects compared to other methods. the aim of the present study is to isolate and identify antibiotic pigment-producing actinomycetes from the soil of the persian gulf and to evaluate the antibiotic activity of their pigments in the second...

In this work, several red-colored paintings of post-Paleolithic schematic style found in 10 different shelters in the vicinity of the Vero River (Huesca) were sampled and subjected to analysis by means of scanning electron microscopy-energy-dispersive X-ray spectrometry (SEM-EDX), Raman spectroscopy, and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). The goal of this re...
