Article history: Received on: 29/11/2014 Revised on: 01/01/2015 Accepted on: 04/02/2015 Available online: 28/03/2015 Microorganisms are capable to produce a wide range of surface active metabolites which are known as biosurfactant. In the present study, the production of biosurfactant from Bacillus subtilis MTCC 441 and evaluation of its synergistic activities with known antibiotics against dru...

Allergic rhinitis (AR) is a common inflammatory disease of the upper airway. Recent evidence suggests that gene‑gene interactions between tumor necrosis factor receptor superfamily 4 (TNFSF4) and B cell lymphocyte kinase (BLK) may have a synergistic effect on T and B cells in determining immunologic aberration, via the nuclear factor‑κB pathway. The present study was performed to evaluate the p...

fifty street dust samples were collected from southern and eastern parts of tehran, the capitalof iran. samples were collected during summer under dry and stable weather conditions. total concentrationsof copper (cu), cadmium (cd), lead (pb), chromium (cr), nickel (ni), zinc (zn), iron (fe), manganese (mn)and lithium (li) were determined. ten samples were then selected for characterization, met...

BACKGROUND Phikud Navakot (PN), a combination of nine herbs, has been used traditionally in Thai medicinal formulas to relieve circulatory disorder. The present study aimed to compare the synergistic antioxidant efficacy and toxicity of the hydroethanolic and water extracts of PN at cellular level. METHODS PN and its nine herbs were extracted with either 50% ethanol or water. All extracts wer...

Key words: in situ stabilization, bioavailable PB, soil remediation This study was conducted to evaluate the effects of P, Mn oxide, and time on bioavailable Pb in five metal-contaminated soils or mine spoils in the absence or the presence of plants, and to evaluate the effect of those treatments on phytoavailability of Pb, Cd, and Zn. The addition of P or Mn oxide reduced bioavailable Pb compa...

the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...

Intercalation-type Nb2O5, based on its inherent structural advantages in energy storage, shows excellent storage characteristics sodium-ion batteries (SIBs). The rapid pseudocapacitive Na-ion insertion/extraction dynamic mechanisms result outstanding rate performance. However, the low electronic conductivity hinders application and development SIBs. Though various modification projects can effe...
