Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Transfer Learning Approaches in Bioprocess Engineering: Opportunities and Challenges

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Transfer learning (TL) has recently emerged as a promising approach to overcoming one of the key limitations of bioprocess engineering: data scarcity. By leveraging knowledge from one bioprocess to another, TL allows existing models and data sets to be reused efficiently, accelerating process development, improving prediction accuracy, and ...

The Adaptation of MCF-7 Breast Cancer Spheroids to the Chemotherapeutic Doxorubicin: The Dynamic Role of Phase I Drug Metabolizing Enzymes

open access: yesMetabolites
Background/Objectives: Drug resistance (DR) is a major challenge in cancer therapy, contributing to approximately 90% of cancer-related deaths. While alterations in drug metabolism are known to be key drivers of DR, their role—particularly in the early ...

Engineering of CoA‐Acylating Butyraldehyde Dehydrogenase for Enhanced 1,3‐Butanediol Production in Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Microbial production of 1,3‐butanediol (1,3‐BDO) offers a renewable route to this versatile C4 chemical. However, the low performance of CoA‐acylating butyraldehyde dehydrogenase (Bld), which contains a catalytic cysteine, limits efficient production in recombinant Escherichia coli (E. coli).

Deciphering the catalytic and pharmacological mechanisms of Coptis chinensis herbzymes to renovate intestinal microenvironment for colitis alleviation

open access: yesBMEMat, EarlyView.
The synthesized CCzymes possess both antioxidant enzyme activity and pharmacological properties inherent to Coptis chinensis. By their antioxidant enzyme activity, CCzymes can attenuate oxidative stress within the inflammatory region of ulcerative colitis (UC), while their pharmacological activity acts on macrophage polarization and the intestinal ...

A Chemical Proteomic Probe for Detecting Dehydrogenases: \u3cem\u3eCatechol Rhodanine\u3c/em\u3e [PDF]

open access: yes, 2012
The inherent complexity of the proteome often demands that it be studied as manageable subsets, termed subproteomes. A subproteome can be defined in a number of ways, although a pragmatic approach is to define it based on common features in an active ...
