Apitherapy and therapeutic properties
Apitherapy is an alternate therapy that relies on the usage of honeybee products, most importantly bee venom for the treatment of many human diseases. Bee venom contains several active molecules such as peptides and enzymes that have advantageous potential in treating inflammation and central nervous system diseases, such as Parkinson’s disease, and Alzheimer’s disease and autoimmume diseases like reumatic and atherosclerosis .Bee venom (BV) is usually associated with pain since, when humans are stung by bees,local inflammation and even an allergic reaction can be produced. It also consists of a mixture of proteins and peptides, including enzymes such as Melittin and phospholipase A2 (PLA2) are the most abundant and studied compounds of BV Stings of hymenoptera can induce IgE-mediated hypersensitivity reactions in venom-allergic patients, ranging from local up to severe systemic reactions and even fatal anaphylaxis. skin is larger than any other organ in humans.

Antifouling Compounds
Increasing awareness of the deleterious effects of toxic components in antifouling coatings has raised interest in the potential for nontoxic alternatives. This book examines how marine organisms from bacteria to invertebrates and plants use chemicals to communicate and defend themselves. Chemicals that prevent colonisation of living surfaces are particularly pertinent to antifouling technology and may inspire new solutions. The challenge is to identify such compounds, identify the means for sustainable production and incorporate them into coatings to give long-term antifouling efficacy.

Antibacterial effects of Algae
An alarm increase in the rate of emerging of resistance bacteria have been causing a great public concern worldwide. This problem of increasing resistance has necessitated the search for safe and effective factors that may be used to treat persistent bacterial infections or modify the currently available antibiotic. This study deals with the antimicrobial potential assessment of ulva flexuosa , ulva flexuosa was collected from at MAZAR ELKHODER. Crude organic extracts were prepared using methanolic and chloroformic extract and tested against 6 indicator microorganisms using the disk diffusion method and also applied against biofilm ( dental plaque).
Animal Models of T Cell-Mediated Skin Diseases
Pharmaceutical companies are spending increasing amounts of money on drug discovery and development. Nevertheless, attrition rates in clinical development are still very high, and up to 90% of new compounds fail in clinical phase I - III trials, which is partially due to lack of clinical efficacy. This indicates a strong need for highly predictive in vitro and in vivo models. The "50th International Workshop of the Ernst Schering Research Foundation" focussed on "Animal Models of T Cell-Mediated Skin Diseases". Such animal models should have impact not only on inflammatory dermatoses but also on other inflammatory disorders due to their model character. The current volume summarises recent advances in animal research that are important for anti-inflammatory drug discovery.

Abiotic Stress Tolerance in Plants : Toward the Improvement of Global Environment and Food
Stresses in plants caused by salt, drought, temperature, oxygen, and toxic compounds are the principal reason for reduction in crop yield. For example, high salinity in soils accounts for large decline in the yield of a wide variety of crops world over; ~1000 million ha of land is affected by soil salinity. Increased sunlight leads to the generation of reactive oxygen species, which damage the plant cells. The threat of global environment change makes it increasingly demanding to generate crop plants that could withstand such harsh conditions. Much progress has been made in the identification and characterization of the mechanisms that allow plants to tolerate abiotic stresses.
A Sea Change: The Exclusive Economic Zone and Governance Institutions for Living Marine Resources
A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth’s surface. They are a critical driver of the earth’s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the sea’s contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).
