A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. [1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage , and from synostosis (ossified junctions), which is the fusion of two or more bones.
Numerous microbial antagonists, including yeasts and bacteria, are isolated from diverse environments such as soil, plants, compost, and oceans for their potential to control plant diseases. For example, endophyte microorganisms found inside guarana seeds and rhizospheric soil have shown their ability to fight harmful pathogens, making them ...

It was discovered that euglonophycin, a euglenoid ichthyotoxin derived from Euglena sanguinea, displays anticancer activity. [4] By sharing a similar chemical structure to solenopsin, an angiogenic inhibitor and alkaloid toxin derived from fire ant venom, euglonophycin has been studied for potential application in natural products and drug development for cancer therapy.

Protacanthopterygii is a superorder of ray-finned fish.They inhabit both marine and freshwater habitats.They appear to have evolved in the Cretaceous or perhaps late Jurassic, originating probably roughly 150 million years ago; fossils of them and the closely related Otocephala are known from throughout the Cretaceous.
Acanthodii or acanthodians is an extinct class of gnathostomes (jawed fishes).They are currently considered to represent a paraphyletic grade of various fish lineages basal to extant Chondrichthyes, which includes living sharks, rays, and chimaeras.
The Gonorynchiformes / ɡ ɒ n ə ˈ r ɪ ŋ k ɪ f ɔːr m iː z / are an order of ray-finned fish that includes the important food source, the milkfish (Chanos chanos, family Chanidae), and a number of lesser-known types, both marine and freshwater. The alternate spelling "Gonorhynchiformes", with an "h", is frequently seen but not official.
Following the convention of the major fish classification organizations (Fish Base, ITIS, Encyclopedia of Life), the Indostomidae are currently placed in the Gasterosteiformes. Morphological traits uniting the flying gurnards (Dactylopteridae) and the Syngnathiformes have long been noted. [10] Most authors, however, placed them with the ...
