3D‐Printed Multidimensional Bionic Mg‐MC/PLGA Composite for Tailored Repair of Segmental Long Bone Defects

Advanced Healthcare Materials, EarlyView.
This study develops 3D‐printed Mg‐MC/PLGA scaffolds with varying Mg concentrations (0–20%). The 5% Mg scaffold shows optimal cytocompatibility, osteogenic activity in vitro, and significantly enhances bone regeneration in rabbits, improving bone volume and mechanical strength.

New and old species of Ommatius Wiedemann (Diptera: Asilidae) from Hispaniola [PDF]

, 2011
Four new species of Ommatius Wiedemann, the female of O. stramineus Scarbrough, and the male of 0. nigellus Scarbrough from Hispaniola are described. A lectotype for O. gwenae Scarbrough and a neotype for O. cinnamomeus are selected.

Experimental studies on diagnosis of death from drowning by means of detection of vegetative planktons (diatoms) II. Detection of diatoms from putrefied and cremated bones of drowned bodies [PDF]

, 1961
A series of experiments have been conducted with ten adult rabbits, drowning them to death in a ditch those water contains diatoms in abundance. The bones (selected ones are the femur, humerus, riHand vertebra) of these drowned rabbits have been buried ...

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

Advanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.

Chthonius hungaricus and Larca lata new to the fauna of Slovakia (Pseudoscorpiones: Chthoniidae, Larcidae) [PDF]

, 2011
Chthonius (Chthonius) hungaricus Mahnert, 1980 and Larca lata (Hansen, 1884) were recorded for the first time from Slovakia. The finding of C. hungaricus in Slovakia is the second known record since its description and the finding of L. lata is the first

Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

Advanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Wild or Domestic? Biometric Variation in the Cat Felis silvestris Schreber [PDF]

, 2007
Investigation of modern biometric data indicates that it may be possible to distinguish wildcats from house cats in many instances. Applying the log-ratio (log-difference) technique to archaeological samples from medieval northern Europe, and to mixed ...

Porous Decellularized Nerve Grafts Facilitate Recellularization and Nerve Regeneration in a Rat Model of Critical Long‐Gap Peripheral Nerve Injury

Advanced Healthcare Materials, EarlyView.
A decellularized nerve graft (DNG) is modified to generate a porous DNG (PDNG). The PDNG is used to repair a 30‐mm peripheral nerve injury (PNI) defect, and is compared with isograft, serving as the standard, and DNG, a widely used alternative. The result shows that PDNG facilitated nerve regeneration in long‐gap PNI, evidenced by better‐aligned axonal

Wrapped Up in Rarity: A Case of Pathologic Fracture-associated Telangiectatic Osteosarcoma

Journal of Orthopaedic Diseases and Traumatology
Telangiectatic osteosarcoma (TO) is one of the rare subtypes of osteosarcoma. As radiographic findings of TO are often confused with aneurysmal bone cysts, early tissue biopsy should be encouraged for diagnostic purposes. We report an original case of TO
