Polysomnography (PSG) is a multi-parameter type of sleep study [1] and a diagnostic tool in sleep medicine.The test result is called a polysomnogram, also abbreviated PSG.The name is derived from Greek and Latin roots: the Greek πολύς (polus for "many, much", indicating many channels), the Latin somnus ("sleep"), and the Greek γράφειν (graphein, "to write").
PSG is a member of the immunoglobulin (Ig) superfamily and contains four immunoglobulin domains. [7] [8]The complete isolation of certain glycoproteins, later classified as pregnancy-specific, within human blood serum occurred in the early 1980s, when experimental techniques like molecular cloning became common practice.

A 2006 review found multiple studies where there were promising results for new drugs in animals, but human clinical studies did not show the same results. The researchers suggested that this might be due to researcher bias, or simply because animal models do not accurately reflect human biology. [ 320 ]
One of Pavlov’s dogs with a saliva-catch container and tube surgically implanted in its muzzle, Pavlov Museum, 2005. The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.

The horse genome is larger than the dog genome, but smaller than the human genome or the bovine genome. [2] It encompasses 31 pairs of autosomes and one sex chromosome pair. [3] As horses share over 90 hereditary diseases similar to those found in humans, the sequencing of the horse genome has potential applications to both equine and human ...

The Titan’s wreckage was seen for the first time in pictures after the Coast Guard announced on Thursday (23 June) that ROVs (remotely-operated vehicles) found its chambers in a sea of debris 1 ...
CH has been found in several species, including cats, dogs, cows and sheep. There are other diseases that lead to cerebellar degeneration , but the loss of Purkinje cells is a clear way to diagnose cerebellar abiotrophy, and the combination of clinical signs is sufficiently unique that cerebellar abiotrophy can easily be distinguished from ...
