Energy metabolic state in hypothermically stored boar spermatozoa using a revised protocol for efficient ATP extraction

Biology Open, 2016
Mammalian spermatozoa utilize ATP as the energy source for key functions on the route to fertilization. ATP and its precursor nucleotides ADP and AMP are regularly investigated in sperm physiology studies, mostly by bioluminescence assays.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Dairy sheep and goats prefer the single components over the mixed ration

Frontiers in Veterinary Science, 2022
Mixed rations provide ruminants with a balanced diet by aiming to prevent selective feeding. However, this is a natural behavior of sheep and goats based on their dietary needs and the nutritional properties of feedstuffs.

Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics

Advanced Functional Materials, EarlyView.
Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Effect of rubber mats and perforation in the lying area on claw and limb lesions of fattening pigs

Animal, 2018
Claw and leg lesions are frequently observed in finishing pigs and are likely to compromise their welfare. Providing softer than the usual concrete flooring may reduce both the frequency and severity of these lesions.

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Management and performance of fattening lambs and goat kids in various rearing systems from Swiss dairy farms

Frontiers in Veterinary Science
Many of the lambs and goat kids born annually on dairy sheep and goat farms are not needed for herd replacement and are slaughtered for meat. The goal of this study was to describe rearing and fattening systems for lambs and goat kids from dairy ...

Circular RNA transcriptome analysis responses to heat stress in the hypothalamus of sows

Journal of Applied Animal Research, 2021
Circular RNAs (circRNAs), as miRNA sponges, have been found to participate in transcriptional control and many important biological processes. Heat stress (HS) severely affects feed intake and milk production of sows. However, the expression and function

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels

Advanced Healthcare Materials, EarlyView.
We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess
