The disassembly of a dying cell into smaller fragments is a fundamental biological process during apoptosis. Recently, a number of distinct morphologic changes have been identified that could mediate the fragmentation of an apoptotic cell. Presented here is a figure that describes the progression of apoptotic cell disassembly.

Rotavirus is the most common cause of diarrhoeal disease among infants and young children. It is a genus of double-stranded RNA viruses in the family Reoviridae. Nearly every child in the world is infected with rotavirus at least once by the age of five. Immunity develops with each infection, so subsequent infections are less severe; adults are rarely affected. There are eight species of this virus, referred to as A, B, C, D, E, F, G and H. Rotavirus A, the most common species, causes more than 90% of rotavirus infections in humans.

Gastrointestinal bleeding (GI bleed) is a common and potentially life-threatening reason for emergency room and intensive care unit admission. This article reports the case of an 83-year-old man with acute GI bleeding from an unusual cause. The clinical information is presented in a step-by-step and question-answer format for learning purposes. This paper is particularly aimed at an internal medicine readership.

Pneumonia is the most important cause of death in children under five years old. Vitamin D is cheap and known to improve the immune system response against respiratory diseases such as tuberculosis. This meta-analysis found three randomized placebo-controlled trials of vitamin D as an additional treatment for pneumonia in 997 infants and children. Taken together, these trials showed no effect of vitamin D cure rates, mortality, time to clinical recovery or duration of hospital stay for pneumonia in children. The quality of evidence is however still low.

Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) is a family of proteins present on the membrane surface of red blood cells (RBCs or erythrocytes) that are infected by the malarial parasite Plasmodium falciparum. PfEMP1 is synthesized during the parasite's blood stage (erythrocytic schizogony) inside the RBC, during which the clinical symptoms of falciparum malaria are manifested. Acting as both an antigen and adhesion protein, it is thought to play a key role in the high level of virulence associated with P. falciparum.

The hippocampus (named after its resemblance to the seahorse, from the Greek ἱππόκαμπος, "seahorse" from ἵππος hippos, "horse" and κάμπος kampos, "sea monster") is a major component of the brains of humans and other vertebrates. Humans and other mammals have two hippocampi, one in each side of the brain. It belongs to the limbic system and plays important roles in the consolidation of information from short-term memory to long-term memory and spatial memory that enables navigation.

Genes consist of multiple sequence elements that together encode the functional product and regulate its expression. Despite their fundamental importance, there are few freely available diagrams of gene structure. Presented here are two figures that summarise the different structures found in eukaryotic and prokaryotic genes. Common gene structural elements are colour-coded by their function in regulation, transcription, or translation.
