Olfaction Contributes to Pelagic Navigation in a Coastal Shark. [PDF]

, 2016
How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied.

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

In ovo omnia: diversification by duplication in fish and other vertebrates : [minireview] [PDF]

, 2009
Gene and genome duplications are considered to be the main evolutionary mechanisms contributing to the unrivalled biodiversity of bony fish. New studies of vitellogenin yolk proteins, including a report in BMC Evolutionary Biology, reveal that the genes ...

Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

Advanced Healthcare Materials, EarlyView.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Structural and functional diversification in the teleost S100 family of calcium-binding proteins

BMC Evolutionary Biology, 2008
Background Among the EF-Hand calcium-binding proteins the subgroup of S100 proteins constitute a large family with numerous and diverse functions in calcium-mediated signaling.

The valvula cerebelli of the spiny eel, Macrognathus aculeatus, receives primary lateral-line afferents from the rostrum of the upper jaw [PDF]

, 1991
In the spiny eel, Macrognathus aculeatus, anterodorsal and (to a lesser degree) anteroventral lateralline nerves project massively to the granular layer of the valvula cerebelli, throughout its rostrocaudal extent.

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

人工種苗生産されたキジハタ仔稚魚の遊泳・摂餌関連形質の発達 [PDF]

, 2019
人工種苗生産されたキジハタ仔稚魚について、遊泳と摂餌に関する形質の発育を記載し発育段階の設定を行った。遊泳では以下の5段階に分けられた：1）遊泳未発達期（D0～1）－遊泳に関する形質は出現しない時期；2）浮遊および胸鰭発達期（D2～9）－肩帯の構成要素が出現する時期；3）尾鰭推進準備期（D10－12～15－17）－脊索末端の上屈が開始・完了する時期；4）尾鰭＋体全体推進期（D15－17～20－22）－脊椎要素が出現・完成し、臀鰭と腹鰭、尾鰭の鰭条が定数になる時期；5）遊泳機能完成期（D20－22 ...

Fully Wireless and Flexible Valves for Multiplexed and Prolonged Intravesical Liquid Release

Advanced Healthcare Materials, EarlyView.
A fundamental mechanism for the simultaneous control of multiple magnetic valves is reported in a miniature soft robotic patch for intravesical drug delivery, enabling fully wireless and programmable liquid release. Integrated with a bioadhesive interface and induction‐coupling‐based liquid volume sensing, the soft robotic patch is promising to enable ...
