Protein secretion is an essential process in all eukaryotes including organisms belonging to the phylum Apicomplexa, which includes many intracellular parasites. The apicomplexan parasites possess a specialized collection of secretory organelles that release a number of proteins to facilitate the invasion of host cells and some of these proteins also participate in immune evasion.

Chloroplasts are essential organelles of plant cells for not only being the energy factory but also making plant cells adaptable to different environmental stimuli. The nuclear genome encodes most of the chloroplast proteins, among which a large percentage of membrane proteins have yet to be functionally characterized.

Membranes serve a number of essential cellular functions. They constitute the boundaries of cells and intracellular organelles, and they provide a surface where many important biological reactions and processes occur. Membranes have proteins that mediate and regulate the transport of metabolites, macromolecules, and ions.

Cellular manifestations of aging are most pronounced in postmitotic cells, such as neurons and cardiac myocytes. Alterations of these cells, which are responsible for essential functions of brain and heart, are particularly important contributors to the overall aging process. Mitochondria and lysosomes of postmitotic cells suffer the most remarkable age-related alterations of all cellular organelles.

The eye lens is composed of fiber cells that differentiate from epithelial cells on its anterior surface. In concert with this differentiation, a set of proteins essential for lens function is synthesized, and the cellular organelles are degraded. DNase II-like acid DNase, also called DNase IIb, is specifically expressed in the lens, and degrades the DNA in the lens fiber cells.

The nuage is a unique organelle in animal germ cells that is known as an electron-dense amorphous structure in the perinuclear region. Although the nuage is essential for primordial germ cell (PGC) determination and devel-opment, its roles and functions are poorly understood.

Cross-cutting finding: The health system could go much further and respond more deliberately to the majority of Ugandans, who live in rural poverty. Currently, the essential package of health services is underfunded, leading to stock-outs of essential medicines and low quality of care. OOP expenditure is high (at over 50 percent of total health expenditure) and there is also high risk of catastrophic health expenditures.
