Antibiotic resistance is becoming more and more common among both pathogenic and non-pathogenic bacteria alike. While measures which limit emerging resistance to our current range antibiotics are being adopted, new drugs are still needed. Traditionally marine invertebrates have been an excellent source of bioactive compounds with potential for pharmaceutical applications. Sponges, which are members of the phylum Porifera, represent an especially rich source of novel compounds. This account outlines the reasoning, procedures, results and applications of our study in which crude chemicals were successfully extracted from two unidentified Hexactinellida sponges and screened for bioactivity against six clinically important bacterial species,...

High Quality Content by WIKIPEDIA articles! Lithonida is an order of calcareous sponges in the class Calcarea in the animal phylum Porifera. Sponges are animals of the phylum Porifera (Pore bearer) (pronounced /p 'r f r /). Their bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells. While all animals have unspecialized cells that can transform into specialized cells, sponges are unique in having some specialized cells that can transform into other types, often migrating between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Данное издание не является оригинальным. Книга печатается по...

Schwamme (Phylum Porifera) sind der alteste rezente Tierstamm der Erde. Insbesondere marine Vertreter sind oftmals mit einem mikrobiellen Konsortium assoziiert, welches hochgradig wirtsspezifisch und phylogenetisch divers ist. Der Mangel an kultivierbaren Vertretern der Schwamm-spezifischen Kladen erschwert dabei eine gezielte funktionelle Charakterisierung. Von besonderem Interesse hierbei ist das exklusiv in marinen Schwammen vorzufindende Candidatus Phylum Poribacteria, fur das bislang kein kultivierter Vertreter vorliegt und sich durch das Vorhandensein einer Nukleoid-ahnlichen intrazellularen Struktur auszeichnet. Im Rahmen dieser Arbeit gelang durch die Anwendung von neuen, Einzelzell-basierten Methoden eine spezifische Verknupfung...

Survivin, a unique member of the family of inhibitors of apoptosis (IAP) proteins, orchestrates intracellular pathways during cell division and apoptosis. Its central regulatory function has inspired several approaches that target survivin for cancer therapy. Analyses in early-branching Metazoa so far propose an exclusive role of survivin as a chromosomal passenger protein, whereas only later during evolution the second, complementary antiapoptotic function might have arisen, concurrent with increased organismal complexity. To lift the veil on the ancestral function(s) of this key regulatory molecule, a survivin homologue of the phylogenetically oldest extant metazoan taxon (phylum Porifera) was identified and functionally characterized....
