Actinomycetes from the Red Sea Sponge Coscinoderma mathewsi: Isolation, Diversity, and Potential for Bioactive Compounds Discovery

open access: yesMicroorganisms, 2020
The diversity of actinomycetes associated with the marine sponge Coscinoderma mathewsi collected from Hurghada (Egypt) was studied. Twenty-three actinomycetes were separated and identified based on the 16S rDNA gene sequence analysis.

Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

open access: yesAdvanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Manifestations of attachment among the late Cretaceous epibenthos fauna (south-east of the Eastern European Province). Article 1. Attachment of Hexactinellide sponges [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Науки о Земле
The fouling of skeletons and shells of benthic organisms and the formation of multi-tiered skeletal formations are characteristic of carbonate-producing Porifera, which participated in the structure of reef communities during the Phanerozoic.

Hierarchical Collagen Nanofiber Gels Recapitulate a Physiologically Relevant Tumor Stromal Microenvironment

open access: yesAdvanced Healthcare Materials, EarlyView.
The collagen nanofiber (CNF) gel supports cancer cell culture, exhibiting cell morphology and cancer‐related protein expression similar to Matrigel. It offers a higher collagen concentration than commercial gels. Additionally, the CNF gel allows replication of the high elasticity of in vivo cancer tissue by controlling collagen fiber sizes, ranging ...

Vascularization of Human iPSC‐Derived Kidney Organoids Using Perfusion Culture, Pre‐Vascularized Collagen Scaffolds, and Decellularized Extracellular Matrix

open access: yesAdvanced Healthcare Materials, EarlyView.
An integrated perfusion‐based culture platform combining pre‐vascularized collagen scaffolds, stromal vascular fraction cells, and kidney decellularized extracellular matrix promotes vascularization of human iPSC‐derived kidney organoids. The platform provides evidence of interactions between vascular networks and glomerular‐like structures and enables

Estrus Synchronization and Conception Rates Using Locally Prepared Methylacetoxy- progesterone Sponges in Cyclic and Acyclic Nili-Ravi Buffaloes (Bubalus bubalis) [PDF]

open access: yesPakistan Veterinary Journal, 2013
A study was conducted to evaluate the efficacy of locally prepared intra-vaginal methylacetoxyprogesterone (MAP) sponges for estrus synchronization and conception rate in cyclic and acyclic Nili-Ravi buffaloes.

Demospongic Acids Revisited

open access: yesMarine Drugs, 2010
The well-known fatty acids with a D5,9 unsaturation system were designated for a long period as demospongic acids, taking into account that they originally occurred in marine Demospongia sponges.
