The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

Amitriptyline is used as an antidepressant and antimigraine drug. It blocks sodium channels on neuronal membrans. Sodium channels generate and propagate action potentials in neurons and muscle. Source: PDB entry 6AGF
Close-up of retail warehouse store purchased frozen turkey waiting in refrigerator freezer compartment to be unwrapped, thawed and prepared for a festive Thanksgiving or Christmas holiday season dinner.
Cell Membrane and Molecules, 3d rendering. Computer digital drawing.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Gram stain of the bacterium, Staphylococcus aureus. This bacteria is gram positive, as such it appears purple after staining due to the thick peptidoglycan. The round cells are also seen in clusters.
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.
The amyloid beta peptide (light blue) is a component of the amyloid precursor protein, which is bound to a cell membrane. The gamma secretase enzyme cuts the free form, that aggregates to amyloid plaques. Source: PDB entries 2beg, 1mwp
Burkitt lymphoma is a form of non-Hodgkin's lymphoma in which cancer starts in immune cells called B-cells. Recognized as a fast growing human tumor, Burkitt lymphoma is associated with impaired immunity and is rapidly fatal if left untreated.
