Tentative exploration of the 3D printing performance of the mixed inks with egg white proteins and mycoprotein fibrous to improve the quality of mycoprotein alternatives.

Mycoprotein (MYC) has unique mycelial properties that make it suitable for mimicking meat fibers. However, the irregular structure of mycelium creates challenges in achieving fiber alignment in meat alternatives. This study explored 3D printing technology to align MYC fibers by formulating inks with various proportions of egg white proteins (EWP) (4 %, 5 %, 6 %, 7 %) and assessing their printing performance.

Influence of mycelial integrity damaged by ultrasonic treatment on product textural properties and in vitro digestibility.

This study investigated the effects of ultrasonic treatment with different intensities (200, 400, and 600 W) and durations (15, 30, and 45 min) on the mycelial integrity, product quality, and in-vitro digestibility of mycoprotein. Results showed that the mycelium was damaged to varying degrees under different ultrasonic parameters. The mycelium showed obvious damage when the time of ultrasonic treatment lasted more than 30 min or the power exceeded 400 W.

Morphology-Based Prediction of Proliferation and Differentiation Potencies of Porcine Muscle Stem Cells for Cultured Meat Production.

Inconsistent efficiency of cell production caused by cellular quality variations has become a significant problem in the cultured meat industry. In our study, morphological information on passages 5-9 of porcine muscle stem cells (pMuSCs) from three lots was analyzed and used as input data in prediction models. Cell proliferation and differentiation potencies were measured by cell growth rate and average stained area of the myosin heavy chain.

The change in nutritional status is related to cardiovascular events in patients with pacemaker implantation: A 4-year follow-up study.

Background: The aim of our study was to evaluate changes in nutritional status as measured by the prognostic nutritional index (PNI) and geriatric nutritional risk index (GNRI) scores, and their abilities to predict clinical prognosis in patients with pacemaker implantation (PMI).

Methods: A total of 595 patients who underwent permanent PMI from January 2011 to December 2020 were included. PNI and GNRI scores were separately calculated at the beginning day of PMI operation and at the end of 12-month follow-up, and their net changes (Δ) were calculated by PNI or GNRI scores at follow-up minus the corresponding scores on admission.
