Antibacterial Activity of a Novel Oligosaccharide from against subsp. .

The present study aims to characterize and predict models for antibacterial activity of a novel oligosaccharide from against subsp. using an adaptive neuro-fuzzy inference system and an artificial neural network. The mathematical predication models were used to determine the optimal conditions to produce oligosaccharide and determine the relationship between the factors (pH, temperature, and time).

Evaluating the biodeterioration enzymatic activities of fungal contamination isolated from some ancient yemeni mummies preserved in the national museum.

Sophisticated mummification using chemical preservation was prevalent in ancient Yemeni civilization as noted in the 4th century B.C. mummies of the National Museum of Yemen, Sana'a, used in this study.

Normalized real-time PCR for diagnosis of H. pylori infection.

Objectives: There is increasing interest in the use of quantitative PCR (q-PCR) for diagnosis of H. pylori infection. However, the assay remains largely unstandardized, making comparison between studies unreliable.
