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
Digital Dispersed corona virus on petri dish. Animation of multiplication of CORONA VIRUS COVID-19
Microbiology. Microorganisms found in the environment, mainly bacteria. Space for text.
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.

Pathogen yeasts infections are treated with fluconazole, that blocks the lanosterol 14-alpha demethylase. This enzyme is essential for the biosynthesis of ergosterol, that is essential for the permeability and rigidity of the fungal plasma membrane. The magnification shows the active site with fluconazole interacting with a heme group. Source PDB entry 5esf.
Lactose-negative biofilm-forming Enterobacter cloacae, resistant to multiple drugs.  Enterobacter cloacae is a member of the normal gut flora. These bacteria are responsable for many hospital-acquired infections for which the mortality rate is generally high.

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.
