I-8: Sperm Chemotaxis towards Progesterone,A Guiding Mechanism That May Be Used to Select The Best Spermatozoa for Assisted Reproduction

Background: Spermatozoa are able to sense an attractant molecule gradient and as a consequence, orient their movement towards the source of the attractant. This mechanism is known as sperm chemotaxis. In recent years, our laboratory contributed to the knowledge of several features of mammalian sperm chemotaxis. These include the size and physiological state of the chemotactic sperm population, ...

Half-Century Journey from Synthetic Organic Chemistry to Mathematical Stereochemistry through Chemoinformatics

My half-century journey started from synthetic organic chemistry. During the first stage of my journey, my interest in stereochemistry was initiated through the investigation on the participation of steric effects in reactive intermediates, cylophanes, strained heterocycles, and organic compounds for photography. In chemoinformatics as the next stage of the journey, I proposed the concept of im...

The Journey into Adulthood: Study of Military Service as a Rite of Passage in Ahmad Mahmoud’s The Neighbors

This paper attempts to investigate the adolescent narrator’s journey into adulthood in Ahmad Mahmoud’s The Neighbor. Considering the central character’s growth into adulthood, the paper argues that the compulsory military service can be fulfilled as a certain ‘rite of passage’ conventionalized within the society, as represented in the narrative. That is because, through this convention, Khaled ...

The Role of Different Sugars, Amino Acids and Few Other Substances in Chemotaxis Directed Motility of Helicobacter Pylori

Objective(s) Motility plays a major role in pathogenicity of Helicobacter pylori, yet there is  scarce data regarding its chemotactic behaviour. The present study was designed to investigate the chemotactic responses of local isolates of H. pylori towards various sugars, amino acids, as well as some other chemical substances. Materials and Methods Chemotaxis was assayed by a modified Adler’s...
