Analysing a Group of Homologous BAHD Enzymes Provides Insights into the Evolutionary Transition of Rosmarinic Acid Synthases from Hydroxycinnamoyl-CoA:Shikimate/Quinate Hydroxycinnamoyl Transferases

Plants
The interplay of various enzymes and compounds gives rise to the intricate secondary metabolic networks observed today. However, the current understanding of their formation and expansion remains limited. BAHD acyltransferases play important roles in the

Transcriptional regulation os phenylalaline biosynthesis and utilization [PDF]

, 2016
Conifer trees divert large quantities of carbon into the biosynthesis of phenylpropanoids, particularly to generate lignin, an important constituent of wood. Since phenylalanine is the precursor for phenylpropanoid biosynthesis, the precise regulation of

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

Advanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Plant sesquiterpene lactones [PDF]

arXiv
Sesquiterpene lactones (STLs) are a prominent group of plant secondary metabolites predominantly found in the Asteraceae family and have multiple ecological roles and medicinal applications. This review describes the ecological significance of STLs, highlighting their roles in plant defense mechanisms against herbivory and as phytotoxins, alongside ...

New Perspectives on Semiconducting Conjugated Oligomers for Neuromodulation in Hydra vulgaris

Advanced Materials Interfaces, EarlyView.
Semiconducting organic compounds, thiophene‐based, modify the rhythmic electrical activity of the cnidarian Hydra vulgaris acting on specific neuronal circuits. The ETE‐S trimer also forms electronically conducting wires in the living tissues of the animal.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

Advanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals
