Flavin Biosynthesis Enhances Extracellular Electron Transfer in Bioengineered Escherichia coli

Advanced Science, Volume 13, Issue 2, 9 January 2026.
Microbial electronics are promising for energy, sensing, environmental, and synthesis applications. E. coli are engineered with extracellular electron transfer (EET) pathways from a microbe that naturally produces current to enable bioelectronics based on E. coli.

Functionalized Donor–π–Acceptor (D–π–A) Organic Linkers for Metal–Organic Frameworks with Extended Visible‐Light Absorption

Chemistry–Methods, Volume 6, Issue 1, January 2026.
Triphenylamine‐based dyes L0‐TA and L1‐TA are synthesized and electrochemically characterized to assess their suitability for photocatalytic hydrogen production via water splitting. Crystallographic simulations confirm their structural compatibility with the MIL‐125 framework, allowing incorporation without steric clashes.

Lipidomic Comparison of Detergent‐Soluble and Detergent‐Resistant Lipid Domains Isolated From Rat Cerebellum and the Effect of Hypoxia–Ischemia Using UPLC‐HDMSE

Journal of Mass Spectrometry, Volume 61, Issue 1, January 2026.
ABSTRACT Hypoxic ischemic encephalopathy (HIE) due to insufficient oxygen or blood flow to the brain can result in inflammation, impaired neurodevelopment, or death. Changes to microdomain lipid composition may contribute to altered structure and function of key regulatory processes; however, knowledge regarding changes to membrane lipid composition ...

Use of quadrupole time-of-flight mass spectrometry for proposal of transformation products of the herbicide bromacil after water chlorination [PDF]

, 2011
The herbicide bromacil has been extensively used in the Spanish Mediterranean region, and although plant protection products containing bromacil have been withdrawn by the European Union, this compound is still frequently detected in surface and ground ...

Molecular basis of domain‐specific angiotensin I‐converting enzyme inhibition by the antihypertensive drugs enalaprilat, ramiprilat, trandolaprilat, quinaprilat and perindoprilat

The FEBS Journal, Volume 293, Issue 2, Page 475-491, January 2026.
Inhibition of angiotensin I‐converting enzyme is an effective strategy for the treatment of hypertension. However, the clinically available ACE inhibitors cause side effects due to nonselective inhibition of the two catalytic domains of ACE (nACE and cACE).

Metabolic signatures of the integrated profile of cardiovascular autonomic modulation and cardiorespiratory fitness in apparently healthy individuals

Physiological Reports, Volume 14, Issue 2, January 2026.
Abstract Cardiovascular autonomic modulation (CAM) and cardiorespiratory fitness (CRF) are well‐established predictors of health. Identifying metabolites associated with integrated CAM‐CRF profiles may help characterize healthy physiological states.

Kinetics of chymotrypsin- and papain-catalysed synthesis of [leucine]enkephalin and [methionine]enkephalin [PDF]

Biochemical Journal, 1984
The proteinase-catalysed synthesis of [Leu]enkephalin and [Met]enkephalin was studied kinetically. N alpha-t-Butoxycarbonyl-amino acids and peptides or their ethyl esters served as acyl donors, and amino acid phenylhydrazides were used as acyl acceptors.

Stable Nitrogen Isotope Analysis of Amino Acids by Orbitrap Mass Spectrometry: Application for Extraterrestrial Samples

Rapid Communications in Mass Spectrometry, Volume 39, Issue 23, 15 December 2025.
ABSTRACT Background Obtaining isotopic data on soluble organic compounds, such as amino acids, in extraterrestrial samples is crucial for understanding their origins, prebiotic chemistry, and potential contamination. Conventional GC‐IRMS requires grams of material to measure isotopic compositions, limiting the analysis of low‐concentration organics in ...

Double labelling immunohistochemical characterization of autonomic sympathetic neurons innervating the sow retractor clitoridis muscle [PDF]

, 2008
Retrograde neuronal tracing and immunohistochemical methods were used to define the neurochemical content of sympathetic neurons projecting to the sow retractor clitoridis muscle (RCM). Differently from the other smooth muscles of genital organs, the RCM
