Adam Boyko was part of a team of scientists who in 2015 discovered that the origin of domestic dogs was near Central Asia 15,000 years ago. [19] In 2016, he was the senior author of a study by Cornell College of Veterinary Medicine researchers that was the largest genetic study of dogs to ever be completed, with a collection of samples that ...
The idea behind cancer dogs is that there may be volatile compounds produced in cancer patients that dogs can detect by scent. In these studies, the compounds are not identified, not tested for, not named. There are many confounders, for example, in the few samples used, there may be other differences being detected by the dogs. [14]
PET, MRI, and overlaid images of a human brain. Positron emission tomography (PET) is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. The theory behind PET is simple enough. First a molecule is tagged with a positron emitting isotope.
PET-MRI systems don't offer a direct way to obtain attenuation maps, unlike stand-alone PET or PET-CT systems. [32] [33] Stand alone PET systems' attenuation correction (AC) is based on a transmission scan (mu - map) acquired using a 68 Ge (Germanium-68) rotating rod source, which directly measures photon attenuation at 511 keV.
Illustration of venereal granulomata on a dog's penis. A canine transmissible venereal tumor (CTVT), also known as a transmissible venereal tumor (TVT), canine transmissible venereal sarcoma (CTVS), sticker tumor and infectious sarcoma, is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.
PennHIP (an acronym for "University of Pennsylvania Hip Improvement Program") is a program which evaluates the quality of the hips in dogs. [1] The program was established at the University of Pennsylvania School of Veterinary Medicine by Gail Smith [2] in 1993, with the primary objective of reducing the prevalence of hip dysplasia in dogs.

Scanning is ridiculously easy. The Plustek features a large silver bar that contains the scanner. You slide the photo through the bar and it's scanned.
Biological systems exist as a complex interplay of countless cellular components interacting across four dimensions to produce the phenomenon called life. While it is common to reduce living organisms to non-living samples to accommodate traditional static imaging tools, the further the sample deviates from the native conditions, the more likely the delicate processes in question will exhibit ...
