Alaa Y.Moustafa  Professor of invertebrates and marine toxins at Faculty of Science, Sohag University, Egypt. I have 24 years of experience  in studying marine invertebrates( specially molluscs) from the Egyptian coast of the Red Sea. The chemical defense strategies in marine mollusk from the Red Sea, isolation of natural products and marine toxins of these species and evaluate their effects in mammalian tissues, microorganisms, and Human cance cell lines

  In 2007 Visiting  Professor  of  the  Center of Advanced studies in Blanes –Spain  to study Natural products from sea hares

Distribution and morphology of defensive acid-secreting glands in Nudipleura (Gastropoda: Heterobranchia), with an emphasis on Pleurobranchomorpha.
Secretion of acidic substances with defence and repellent properties is known in several metazoan taxa, including Gastropoda. Here we investigate and compare defensive acid-secreting cell types of various genera within the heterobranch taxon Pleurobranchomorpha by analysing the sizes and distribution of the secretory epithelial cells and subepithelial glands of the epidermis. Additionally, we investigate the median buccal gland (MBG), which ... Read more

The ontogeny of appendages and carapace of Neonesidea schulzi (Ostracoda: Bairdiidae) from the Red Sea coast, Egypt
The ostracod genus _Neonesidea _is broadly distributed in shallow marine waters. The ontogeny of the _N. schulzi _(Bairdiidae) is described in detail by studying the development of the appendages and variations in carapace form, size and structure. _Neonesidea schulzi _has eight post-embryonic instars, and a gap in its ontogenetic development during instar A-6, where no new _Anlage _is added. The ... Read more

Assessment of Biochemical and Histopathological Effects of Crude Venom of Cone Snail Conus flavidus on albino Mice
The genus Conus is equipped with a unique venomous mixture of conopeptides which secreted for predation and defense purposes. This work is aiming to explore and determine the effect of the crude venom of Conus flavidus, a wormhunting cone snail inhabiting the Red Sea, on the oxidant/ antioxidant system in mice using some oxidative stress biomarker assays. In addition to ... Read more

A review of the genus Berthellina (Mollusca: Heterobranchia: Pleurobranchidae) in the Red Sea based on molecular and anatomical data
The genus _Berthellina_ Gardiner 1936 (Mollusca: Heterobranchia: Nudipleura) is a circumtropical group of pleurobranchid sea slugs including species with uniform coloration patterns, varying from yellow and orange to red. The systematics of Berthellina is in need of a revision for many areas of the world, particularly in the Indo-West Pacific region, where more than one species seem to occur. In ... Read more

Immunotoxicity of skin acid secretion produced by the sea slug Berthellina citrina in mice spleen: Histological and Immunohistochemical study
Acid secretion containing sulfuric and hydrochloric acids is a fascinating defensive phenomenon within many groups of marine organisms. This study aimed to investigate the mice spleen histology and immunotoxicity using skin acid secretion (SAS) of the sea slug _Berthellina citrina_ after oral administration. The spleen showed atrophy in the white pulp, decrease in the splenocytes density, megakaryocytes cytoplasmic degeneration as ... Read more
