Engineering of Transmembrane Alkane Monooxygenases to Improve a Key Reaction Step in the Synthesis of Polymer Precursor Tulipalin A

Angewandte Chemie International Edition, Accepted Article.
The α‐methylene‐γ‐butyrolactone tulipalin A, a defense compound found in tulips, can polymerize via addition at the vinyl group or via ring‐opening polymerization, making it a highly promising monomer for bio‐based polymers. Since the biosynthesis of tulipalin A in plants remains elusive, we propose an alternative pathway for its synthesis starting ...

Titanium implant surface roughness after different implantoplasty protocols: A laboratory study

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1315-1321, December 2022., 2022
Abstract Objective To compare the surface roughness of sandblasted, large grit, acid‐etched (SLA) surfaced titanium discs, after implantoplasty (IP) with different combinations of rotating instruments without or with the subsequent use of a silicone polisher.

Assessing the efficiency of ethyl acetate for lipid extraction as an alternative to the Folch method in selected marine low‐trophic species

Journal of the American Oil Chemists' Society, EarlyView.
The EtOAc method offers a straightforward and environmentally friendly protocol for lipid extraction, showing efficiency comparable to the Folch method, particularly in extracting lipids with high proportions of neutral lipids and free fatty acids. Abstract The recognized health benefits associated with marine omega‐3 polyunsaturated fatty acids (PUFAs)

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

The Anatomical Record, EarlyView.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.
