Ganoderma resinaceum tolerated sodium chloride salt stress within a range of 0 mM till 300 mM. It responded to salt stress with fluctuation in proline formation at different NaCl concentrations. However,the mycelial dry weight,total protein contents and exopolysaccharides did not changed considerably. Increasing sodium chloride concentration led to morphological alteration in fungal mycelia wit...

Dielectric spectroscopy is used to investigate fundamental length scales describing the structure of hyaluronic acid sodium salt (Na-HA) semidilute aqueous solutions. In salt-free regime, the length scale of the relaxation mode detected in MHz range scales with HA concentration as c(HA)(-0.5) and corresponds to the de Gennes-Pfeuty-Dobrynin correlation length of polyelectrolytes in semidilute s...

A comparison of two colorimetric procedures for the determination of serum glutamic oxaloacetic acid (SCOT) showed that both the dinitrophenylhydrazine and diazonium salt colorimetric assay procedures have good precision and reproducibility acceptable to most clinical laboratories. Babson’s diazonium salt procedure (3) definitely shows greater precision in the important borderline range of valu...

lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. table salt is one the mostly used food additive with unique place in food consumption. although purified table salt is expected to have lower level of contamination, some iranians still prefer to use rock salt. use of rock salt for food purposes has be...

The cement industry plays a fundamental role in the economic growth of country for both developed and under countries. However, it is posing great threat to environment. This study aimed investigate key environmental risks associated with industry. assessment was conducted eight industries situated Salt Range area, Pakistan. Ambient air monitoring carried out according USEPA prescribed merthods...

A very simple annulation reaction was designed, allowing an imidazole moiety to be fused onto a range of pyridine-based derivatives. The methodology consists of an activation step via the formation of a pyridinium salt to increase the electrophilicity of the pyridine ring, followed by a cascade reaction triggered by a nucleophilic attack of the iminium moiety. Depending on the pyridinium salt, ...

Characean plants provide an excellent experimental system for electrophysiology and physiology due to: (i) very large cell size, (ii) position on phylogenetic tree near the origin of land plants and (iii) continuous spectrum from very salt sensitive to very salt tolerant species. A range of experimental techniques is described, some unique to characean plants. Application of these methods provi...

RANGE EXPANSION OF BLACK MANGROVES (AVICENNIA GERMINANS) TO THE MISSISSIPPI BARRIER ISLANDS.—The expansion of the black mangrove (Avicennia germinans) into Gulf of Mexico salt marshes is among the many climateinduced poleward range shifts of tropically associated marine plants and animals that have been documented in recent decades (Perry et al., 2005; Lasram and Mouillot, 2009; Fodrie et al., ...
