This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Mast cells in cell culture. Mast cells (mastocytes) are cells of the immune system and represent an important link between the innate and acquired immune response.They arise from precursor cells in the bone marrow and migrate as immature cells to many tissues, especially those in close contact with the outside world, where they differentiate.
Endogenous regeneration in the brain is the ability of cells to engage in the repair and regeneration process. While the brain has a limited capacity for regeneration, endogenous neural stem cells, as well as numerous pro-regenerative molecules, can participate in replacing and repairing damaged or diseased neurons and glial cells.
Neural stem cells differentiating to astrocytes (green) and sites of growth hormone receptor shown in red. There are two basic types of stem cell: adult stem cells, which are limited in their ability to differentiate, and embryonic stem cells (ESCs), which are pluripotent and have the capability of differentiating into any cell type.
Kidney and nerve tissue cells can form memories much like brain cells, one new study has found. Another recent study says that memories of obesity stored in fat tissue may be partly responsible ...
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
Arthritis: When senior dogs develop changes in their vertebral bones, their spine can be pressed upon, and they can display the type of changes in the back legs that you describe.
2. Hollow Food Puzzles. As the name implies, these food puzzles are hollow, as they are meant to be filled with food. Their shape makes it challenging for dogs to extract the food, keeping them ...
