Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

High Cell Density Cultivation of HEK293 Cells Using a 2L Membrane‐Stirred Bioreactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The use of perfusion systems for the continuous cultivation of animal cells at high cell density (HCD) for the production of recombinant proteins, viruses, and viral vectors has many advantages. Besides an enhancement of volumetric productivity and high cell viability, the product quality can be improved through a steady‐state environment ...

Ten‐year follow‐up of bilateral gingival recession treatment: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background This work aims to present a 10‐year follow‐up of a young patient who underwent treatment with collagen matrix (CM) combined with enamel matrix derivative (EMD) for bilateral gingival recessions in the maxillary canine region. Methods The patient, a 25‐year‐old woman, presented with bilateral Cairo type 1 recessions.

A Comparison of Blade Tip-Timing Data Analysis Methods

, 1999
The determination of the vibration characteristics of rotating engine blades is very important for fatigue failure considerations. One of the most promising techniques for measuring blade vibrations is blade tip-timing. Three vibration analysis methods

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Applications of Biomaterials in Separators for Secondary Batteries

Carbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
