New type of placental structure discovered in animals

New type of placental structure discovered in animals The Cyclostomata is an ancient group of aquatic colonial suspension-feeders from the phylum Bryozoa. The fact that they have unique placentae has been discovered by researchers at St Petersburg University and the University of Vienna. The coenocytes, i.e. large multinucleate cell structures, originate via nuclear multiplication and cytoplasmic growth among the cells surrounding the early embryo. Interestingly, the coenocytes are commonly found among fungi and plants, yet are quite rare in animals. It is the first time coenocytes have been discovered in placenta. Biologists are well aware that the cells of the living organisms are incredibly different in the way that they behave. They may happen to form a multinucleate structure resulting from cell fusion, i.e. so-called syncytium with a single membrane. Such behavior ensures nutrient circulation with no resources and time spent on transporting between the cells.

Biodegradable Nanoprobes Improve Cancer Diagnosis

Biodegradable Nanoprobes Improve Cancer Diagnosis Written by AZoNanoMar 12 2021 New nanoprobes, which were recently developed by Imperial College London (ICL) and tested in zebrafish, could help identify cancer more precisely and may support the diagnosis and treatment in the days to come. Purple cancer cells are labeled using bioharmonophores (white label). Image Credit: Imperial College London. To clearly visualize tumors in the body for cancer diagnosis, physicians can utilize miniature optical probes (nanoprobes) that illuminate upon binding to tumors. Such nanoprobes enable doctors to detect the size, shape and location of tumors in the body. The majority of the nanoprobes are fluorescent, which means they absorb light of a particular color, such as blue, and then produce a background light of a different color, such as green.

Tumours illuminated brightly and precisely with new biodegradable nanoprobe

E-Mail To highlight tumours in the body for cancer diagnosis, doctors can use tiny optical probes (nanoprobes) that light up when they attach to tumours. These nanoprobes allow doctors to detect the location, shape and size of cancers in the body. Most nanoprobes are fluorescent; they absorb light of a specific colour, like blue and then emit back light of a different colour, like green. However, as tissues of the human body can emit light as well, distinguishing the nanoprobe light from the background light can be tough and could lead to the wrong interpretation. Now, researchers at Imperial College London have developed new nanoprobes, named bioharmonophores and patented at Imperial, which emit light with a new type of glowing technology known as second harmonic generation (SHG).
