RFHX31XK–Computer model showing the structure of a molecule of botulinum neurotoxin (BTX) type A. This neurotoxic protein is produced by the bacterium Clostridium botulinum and related species. It is also produced commercially for medical, cosmetic, and research use, where it is used in for the treatment of upper motor neuron syndrome, focal hyperhidrosis, blepharospasm, strabismus, chronic migraine and bruxism. It is also widely used in cosmetic treatments, such as Botox injections.

RFHBX3XB–Functions of autophagy, computer illustration. Autophagy (autophagocytosis) is the natural mechanism that destroys unnecessary or dysfunctional cellular components and recycles their materials. Autophagy is important in different types of stresses, including starvation, infections, aging, type II diabetes, embryogenesis and other pathological and physiological conditions.

RF2BK5A21–Human ACE2 receptor, computer illustration. The receptor is an angiotensin-converting enzyme 2 (ACE2) type receptor, which is the entry route for all coronavirus particle types. Covid-19, which emerged in Wuhan, China, in December 2019, is a mild respiratory illness that can develop into pneumonia and be fatal in some cases. It is caused by the SARS-CoV-2 (previously 2019-nCoV) coronavirus.

RFHBX44F–Epstein-Barr virus (EBV), computer illustration. EBV, also known as human herpes virus 4, is 1 of 8 herpes viruses that infects humans. It is best known as the cause of infectious mononucleosis (glandular fever), but is also associated with some forms of cancer, including Burkitt's lymphoma. In both infections, the virus infects one type of white blood cell, the B lymphocytes. Infection with EBV is common and usually harmless; additional factors potentiate the development of more serious diseases.
RFMYDR19–Treatment and prevention of stroke due to atherosclerosis. Conceptual illustration showing an arterial blockage (expanded view at upper right) causing a stroke (cerebrovascular accident, CVA). This stroke is due to a build-up of the plaque that forms in atherosclerosis. This blockage causes an interruption (occlusion) of the oxygenated blood supply. This will cause a stroke, where the brain is damaged due to hypoxia (lack of oxygen). The grey area at upper right shows the area of the brain affected by lack of oxygen. This type of stroke is known as an atherosclerotic stroke. Common causes are

This stroke is due to a build-up of the plaque that forms in atherosclerosis. This blockage causes an interruption (occlusion) of the oxygenated blood supply. This will cause a stroke, where the brain is damaged due to hypoxia (lack of oxygen). The grey area at upper right shows the area of the brain affected by lack of oxygen. This type of stroke is known as an atherosclerotic stroke. Common causes are high blood pressure and arterial disease.
RFMYDRDF–Food infection caused by Shigella bacteria, conceptual illustration. Shigella sp. are Gram-negative rod-shaped bacteria (bacilli) and are the causative agent of human shigellosis. They infect the large intestine and cause dysentery, which can vary in severity from a mild attack of diarrhoea to an acute infection.

RFHX3220–Interferon gamma, molecular model. Interferon gamma is produced by certain immune cells (T cells, dendritic cells and NK cells) as part of the immune response to invading pathogens and tumours. It is able to directly inhibit viral replication and also prompts neighbouring cells to produce protective enzymes and activates immune system cells.
