Normal, appropriate sorrowful response to an immediate cause. It is self-limiting and gradually subsides within a reasonable time.

A convolution on the inferior surface of each cerebral hemisphere, lying between the hippocampal and collateral sulci. (Dorland, 28th ed)

A structural subclass of streptogramins. They are cyclic hexadepsipeptides with approximate molecular weight of 800 that contain a characteristic 3-hydroxy picolinoyl exocyclic component.

The branch of science concerned with the means and consequences of transmission and generation of the components of biological inheritance. (Stedman, 26th ed)

A bacteriostatic antibacterial agent that interferes with folic acid synthesis in susceptible bacteria. Its broad spectrum of activity has been limited by the development of resistance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p208)

A member of the Rho family of MONOMERIC-GTP-BINDING PROTEINS. It is associated with a diverse array of cellular functions including cytoskeletal changes, filopodia formation and transport through the GOLGI APPARATUS. EC 3.6.1.-.

Cell-surface proteins that bind GAMMA-AMINOBUTYRIC ACID with high affinity and trigger changes that influence the behavior of cells. GABA-A receptors control chloride channels formed by the receptor complex itself. They are blocked by bicuculline and usually have modulatory sites sensitive to benzodiazepines and barbiturates. GABA-B receptors act through G-proteins on several effector systems, are insensitive to bicuculline, and have a high affinity for L-baclofen.

A genus of bacteriophages of the family MICROVIRIDAE. The genome consists of isometric single-stranded DNA.

Phase of the cell cycle following DNA synthesis and preceding mitosis. The chromosomes are tetraploid in this phase.

Phase of the cell cycle preceding protein systhesis. The subphases of G1 include competence, entry (G1a), progression (G1b), and assembly (G1c), based on the effects of limiting growth factors, nutrients, or inhibitors.
