3D‐Printed Titanium Implants with Bioactive Peptide‐Polysaccharide Scaffolds for Personalized Bone Reconstruction

open access: yesAdvanced Healthcare Materials, EarlyView.
Porous 3D‐printed titanium implants are made bioactive by integration with a supramolecular peptide‐hyaluronic acid nanofibrillar scaffold, without the addition of exogenous cells or growth factors. Uniform filling of the implant architecture promotes vascularized, spatially homogeneous bone regeneration, significantly enhancing osteogenesis throughout

Maritrema orensenseandMaritrema bonaerense(Digenea: Microphallidae): Descriptions, Life Cycles, and Comparative Morphometric Analyses [PDF]

open access: yesJournal of Parasitology, 2013
We elucidate the life cycle of Maritrema orensense for the first time and experimentally confirm that of the sympatric Maritrema bonaerense. In Argentinean estuaries, both species parasitize the cochliopid snail Heleobia australis as first intermediate host, the grapsid crabs Neohelice granulata and Cyrtograpsus angulatus as second intermediate hosts ...

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

open access: yesAdvanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

COMPARATIVE-MORPHOLOGICAL AND ECOLOGICAL AND BIOLOGICAL ANALYSIS OF CESTODA ERINACEOLEPIS ERINACEI (GMELIN, 1789) GULYAEV ET IRZHAVSKY COMB.N

open access: yesЮг России: экология, развитие, 2014
The article gives the historical background of the tribe and clan. We consider a diagnosis of the genus. Given distribution of the species, its definitive and intermediate hosts, life cycle, the localization of the cestode in the host's body.

Integrating species distribution models, genetics and morphology to infer species dynamics of New Zealand Phaulacridium grasshoppers : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Zoology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
Species comparison studies have used a number of different methods that can contribute to our understanding of processes that influence the differences and similarities observed between species.

Biological compatibility between two temperate lineages of brown dog ticks, Rhipicephalus sanguineus (sensu lato) [PDF]

open access: yes, 2018
Background: The brown dog tick Rhipicephalus sanguineus (sensu stricto) is reputed to be the most widespread tick of domestic dogs worldwide and has also been implicated in the transmission of many pathogens to dogs and humans.

Description and ontogenetic morphometrics of nymphs of Belminus herreri Lent & Wygodzinsky (Hemiptera: Reduviidae, Triatominae) [PDF]

open access: yesNeotropical Entomology, 2005
For the first time all instars of a species of the genus Belminus are described based on laboratory F1 generation specimens from adults caught in department of Cesar, Colombia. Ontogenetic morphometrics of postembryonic head development was made, suggesting that the greatest changes occur between the 1st and 2nd instars.

Biocatalytic Nanoregulators Restore Joint Redox‐Immune Homeostasis in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Mesenchymal stem cell‐derived extracellular vesicles (EVs) coat ruthenium‐loaded metal‐organic frameworks (Ru@ZrMOF), creating a targeted therapeutic (Ru@ZrMOF/EVs). This platform scavenges ROS, generates oxygen, and polarizes macrophages from M1 to M2, alleviating inflammation, inhibiting pannus, promoting cartilage repair, and downregulating HIF‐1α ...

Micro-CT Characterization of Human Trabecular Bone in Osteogenesis Imperfecta [PDF]

open access: yes, 2011
Osteogenesis imperfecta (OI) is a genetic syndrome affecting collagen synthesis and assembly. Its symptoms vary widely but commonly include bone fragility, reduced stature, and bone deformity.

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...
