Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Inhibition of apricot polyphenol oxidase by combinations of plant proteases and ascorbic acid

Food Chemistry: X, 2019
The present research investigates the long term inhibition of enzymatic browning by inactivating the polyphenol oxidase (PPO) of apricot, using combinations of plant proteases and ascorbic acid (AA).

Biodegradable Wireless Soil Urea Sensor Using Metamaterial Perfect Absorber for Distributed Deployment in Precision Agriculture

Advanced Materials Technologies, EarlyView.
In this study, we propose a biodegradable wireless soil urea sensor for precision agriculture. The sensor's electromagnetic response varies depending on the urea concentration, allowing the measurement of relative soil urea concentrations by analyzing the time‐transient electromagnetic response.

Bioprotection using a selected strain of Metschnikowia pulcherrima as an alternative to SO₂ for preventing the browning of white grape must

IVES Technical Reviews
Enzymatic browning of grape must still represent one of the major problems in oenology today (Li et al., 2008), and is especially serious when the grapes are affected by grey rot (Ky et al., 2012).

Enzymatic Browning of Stored Parsnip Roots1

Journal of the American Society for Horticultural Science, 1972
Abstract We established that surface browning in parsnips is due to enzymatic oxidation of phenolic compounds by an active polyphenoloxidase system. Potential browning was highest in the tissue immediately below the surface. The total phenolic content was lowest on the root surface and highest in the vascular cylinder region, whereas ...

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study

Advanced Science, EarlyView.
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...

Enzymatic Study on Browning and Respiration of Potato

Journal of the agricultural chemical society of Japan, 1955
馬鈴薯より分離したtyrosinaseは酸化還元色素で阻害され,その阻害は電位の低いもの程強い. 馬鈴薯切片は調製後時間の経過につれて酸素吸収が増加し, 70時間位で最高に達する. 酸素吸収が増加している切片は酸化還元色素で酸素吸収が阻害され,其の様子は分離したtyrosinaseに類似する. 馬鈴薯切片の酸素吸収の増加とmethylene blueの脱色時間とは反対の結果を示し,酸素吸収の増加は脱水素系に無関係に行われている.併し馬鈴薯の熱抽出物を加えるとmethylene blueの脱色時間は短かくなる. 新鮮な切片はmono-iodoacetateで酸素吸収が阻害され, thioureaでは阻害されない.
