Antibacterial peptides were isolated from immune haemolymph of Rhinoceros beetle (Oryctes rhinoceros L.) larvae and evaluated for antibacterial activity against bacterial pathogens, viz., Klebsiella pneumoniae, Micrococcus luteus, Bacillus subtilis, Paenebacillus macerans and Pseudomonas sp. The peptides were found to be stable upto 37°C and antibacterial activity observed at pH 7.0. The peptid...

High performance liquid chromatography (HPLC) is often the method of choice for the separation of nonvolatile solutes. LC commonly exhibits longer analysis times, larger pressure drops and lower efRciency than either supercritical Suid chromatography (SFC) or gas chromatography (GC). The greater viscosities and lower diffusivities of liquids compared to those of supercritical Suids or gases are...

The carbobenzyloxy (cbz) protecting group is evaluated for it's potential to enhance the resolution of chiral amine enantiomers using high-performance liquid chromatography (HPLC) and supercritical fluid chromatography (SFC). A series of cbz derivatives of commercially available racemates was prepared and analyzed by enantioselective chromatography using a variety of mobile phases and polysacch...

Dracocephalum heterophyllum Benth is well-known for its ability to alleviate liver heat. In this study, ethyl acetate extracts were evaluated on mouse models of nonalcoholic steatohepatitis and fibrosis. After 6 8 weeks treatment, serum parameters gene expressions in tissue samples, as well stained sections, demonstrated that the effective treating these diseases. The principal bioactive consti...

polycyclic aromatic hydrocarbons (pahs) which are toxic pollutants are released by various sources of urban combustion. ahvaz in iran with around a million population and the industrial and oil centers, has encountered air quality problems. samples of dibenzo (a,h) antheracen were collected from six stations in ahvaz particle and gas phase in summer 2010. dibenzo(a,h) antheracen were collected ...

Pharmaceutical analysis based on chromatographic separation is an important part of studies aimed at developing routine quality analysis of drugs. High-performance liquid chromatography (HPLC) is one of the main analytical techniques recommended for drug analysis. Although it meets many criteria vital for analysis, it is time-consuming and uses a relatively high amount of organic solvents compa...

This is a review of analytical methods, such as spectrophotometry, derivative spectrophotometry and various chromatographic (gas chromatography-GC, high-performance liquid chromatography-HPLC, thin-layer chromatography-TLC, high-performance thin-layer chromatography-HPTLC, liquid chromatography-tandem mass spectrometry-LC-MS, microchip electrophoresis-MCE, capillary electrophoresis-CE) and elec...

Abbreviation Key HBSS = Hanks balanced salt solution, HPLC = high performance liquid chromatography, IL-2 = interleukin-2, NK = natural killer, SAPLIP = saposin-like protein.
