Synthesis of some novel benzoxazolinonylcarboxamides as potential  anti-inflammatory agents  

Posted on 1. July, 2014.

Nonsteroidal anti-inflammatory drugs (NSAIDs) represent one of the most extensively utilised classes of pharmaceutical agents worldwide, and have been used in the treatment of pain, nociception, fever and inflammatory diseases, especially arthritis.

Speciation studies of Co(II), Ni(II) and Cu(II) complexes of L-valine in acetonitrile-water mixtures

Posted on 20. December, 2013.

Speciation study of essential metal ion complexes with amino acids is useful to understand the role played by the active site cavities in biological molecules and the bonding behaviour of protein residues with the metal ion. Chemical speciation of a molecule is governed by its structure and solvent effects. Hence, in recent years, researchers have shown interest in the study of metal ions interaction with various ligands

Diversity and distribution of avian lice on Greater Flamingo chicks (Phoenicopterus roseus) in Algeria

Posted on 20. December, 2013.

Interactions between wild birds and ectoparasites have received extensive attention by ecologists because the distribution and dynamics of parasites may drive population processes of their hosts by influencing survival and productivity. Areas of interest include the influence of host morphology and behaviour on ectoparasite numbers and distribution, and their vertical or horizontal transmission. Many studies reported that close proximity of individuals facilitates host infestation with colonial birds harbouring a large number and a great diversity of ectoparasites. Thus, chewing lice usually are transferred by direct contact and, less frequently, by louse flies.

Theoretical study of N2O formation from NO and H2 over Au nanoparticles

Posted on 20. December, 2013.

One of the exciting discoveries in the field of heterogeneous catalysis in the last decade has been the surprisingly high activity of gold-based catalysts towards several reactions of industrial and environmental importance. Gold, formerly considered as an uninteresting material for catalysis because of its unreactive character, was found in the form of nanoparticles, to be an extremely efficient catalyst for a number of important reactions such as CO oxidation, methanol decomposition, and the hydrogenation of unsaturated hydrocarbons.

Antimalarial and antileishmanial activity of novel 13-benzyl-15,16-bisnorlabdane derivatives

Posted on 20. December, 2013.

Malaria and leishmaniasis are protozoan diseases with a high mortality rate affecting millions of people every year. Globally, an estimated 3.3 billion people were at risk of malaria in 2011, and estimates by the World Health Organization (WHO) have indicated that approximately 80% of cases and 90% of deaths occur in Africa, with children less than five years of age and pregnant women most severely affected. The Plasmodium falciparum parasite is responsible for most fatal cases of malaria. Leishmaniasis threatens about 350 million people in 98 countries or territories around the world, about 2 million estimated new cases occurring each year, and 12 million people are believed to be currently infected. The synthesis of 12 novel related-labdane-related natural products with antiparasitic activity is reported.

Science Progress

Posted on 20. December, 2013.

In 2013, Science Progress has continued to deliver topical and diverse reviews by leading authorities from across the world.

In the latest issue, Professor Rod Bilton discusses the impact of climate change and diet on the evolution of human energy metabolism in “Averting comfortable lifestyle crises”.

Through the last three millennia observant physicians have noted the association of inappropriate diets with increased incidence of obesity, heart disease, diabetes and cancer, and over the past 300 years doctors in the UK observed that overeating increased the incidence of these diseases.
