Megakaryocyte quantitation [PDF]

open access: yesJournal of Clinical Investigation, 1968
A method is described for the quantitation of megakaryocytes. In this technic bone marrow sections obtained at the time of maximal marrow uptake of previously injected plasma bound (59)Fe are counted for radioactivity as well as the number of megakaryocytes and nucleated red cells.

The Quantitative Electrokymograph [PDF]

open access: yesCirculation, 1951
The quantitative electrokymograph has been developed in an effort to provide an instrument which will be easier to operate than the electrokymographic equipment currently available. In addition, provision has been made for the recording of both border-motion phenomena and densitometric changes within the heart and great vessels.

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Determination of Chitin Content in Insects: An Alternate Method Based on Calcofluor Staining

open access: yesFrontiers in Physiology, 2020
Chitin is an aminopolysaccharide present in yeast cells and arthropod cuticle and is one of the most abundant biopolymers. The conventional methods for the quantitation of chitin content in biological samples are based on its hydrolysis (acid or ...

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...
