Abstract:

Oxygenic photosynthesis is the process in plants, algae and cyanobacteria which converts light energy from the sun into carbohydrates and at the same time produces oxygen from water. Both carbohydrates and oxygen are essential to sustain life on earth. Sunlight is thus a necessity for life, but it can also cause severe problems for photosynthetic organisms, which have evolved several remarkable acclimation systems to cope with light fluctuations in the environment. In higher plants the light driven reactions of photosynthesis proceed in the chloroplast thylakoid membranes highly organized into

Abstract:

Diet has for many years been known to play a key role in the development of chronic diseases. There are clear associations between consumption of vegetables, fruits and berries, and risk of cardiovascular diseases, the number one cause of death in the world. To maintain homeostasis of the vascular wall the balance between angiotensin II, nitric oxide and reactive oxygen species is of great importance in order to affect the development of cardiovascular diseases. Angiotensin II, a potent vasoconstrictor causing cell growth and nitric oxide, a signalling molecule influencing the vascular system

Abstract:

Antigen expression through the Chloroplast Transformation Technology (CTT) produces bioencapsulated subunit-vaccines, capable of eliciting immune responses when delivered orally. Considerable challenges to effective plant-based vaccines are the normalization of dosage and preservation of accumulated antigen, which is complicated by variable high water content and protease activity. This study critically examines the efficacy of lyophilization in dehydrating plant-tissues and preserving plant-derived antigens with vaccine potential. Lyophilization was optimized through gravimetric analysis usin

Abstract:

Ladybird beetles produce a range of alkaloid compounds which are found a high concentration in the haemolymph and released in response to perceived threat. These alkaloids are thought to function as agents of chemical defence and a small number have been shown to antagonise the nicotinic acetylcholine receptor. As intraguild predators, the chemical defence may be under selective pressure from other predatory insects, the alkaloids may therefore have evolved to target insects predominantly. To discover if other ladybird alkaloids show activity at nAChRs and investigate mode of action, alkaloids

Abstract:

The use of indigenous plants by native healers has been in healthcare system for a long time. It is prevalent in many developing countries because of its wide benefits and rising popularity. But less is known about the chemistry behind the medicinal properties of those indigenous plants. Unraveling the knowledge helps develop drugs based on the indigenous plants and understand their mechanisms of the action. Malaria happens to be a vector borne protozoan parasitic disease which has been reported to affect 229 million people in 2019. Use of indigenous plant for treating malaria is widely practi

Abstract:

One of the pathological hallmarks of Alzheimer's disease (AD) is the amyloid plaque deposition in aging brains by aggregation of amyloid-? (A?) peptides. In this study, the effect of chloroplast derived myelin basic protein (MBP) fused with cholera toxin subunit B (CTB) was investigated in advanced diseased stage of human and mouse AD brains. The CTB-fusion protein in chloroplasts facilitates transmucosal delivery in the gut by the natural binding ability of CTB pentameric form with GM1 receptors on the intestinal epithelium. Further, bioencapsulation of the MBP within plant cells confers prot
