Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

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

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used in the Spanish Mediterranean region, and although plant protection products containing bromacil have been withdrawn by the European Union, this compound is still frequently detected in surface and ground ...

Candidate Obesity Biomarkers Identified Through Multi‐Omics Analysis, Mendelian Randomization, and Mediation Analysis

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Untargeted metabolomics and lipidomics integrated with two‐sample bidirectional Mendelian randomization identified hexanoylglycine and LPC (16:0) as obesity‐associated biomarkers. Hexanoylglycine and LPC (16:0) showed potential causal links to BMI, were partially mediated by immune cell traits, and were associated with blood pressure, indicating ...

Optimization of Hot and Cold‐Water Extractions of Cistus salviifolius L. for Enhanced Phenolic Content and Antimicrobial Efficacy

ChemistrySelect, Volume 11, Issue 13, 6 April 2026.
This study optimized cold and hot water extractions for maximizing phenolic content and antibacterial activity against S. aureus and P. aeruginosa. Hot water yielded higher total phenolics and were more effective against P. aeruginosa. Conversely, cold water enriched specific ellagitannins (punicalagin and cistusin), showing potent, targeted ...

Traditional Chinese Herbal Formula XuMingZhuSan Alleviates Neuronal Ferroptosis in Rats After Stroke by Activating the NRF2/GPX4/SLC7A11 Pathway

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
Traditional Chinese herbal formula XuMingZhuSan showed its efficacy in treating stroke. It was capable of attenuating neuronal damage and mitochondrial damage and reducing infarction volume in rats with stroke. Mechanically, XuMingZhuSan might treat stroke by relieving neuronal ferroptosis via activating the NRF2/GPX4/SLC7A11 pathway.

The synthesis and characterization of polypeptide-adriamycin conjugates and its complexes with adriamycin. Part I [PDF]

, 1985
Poly(α-l-glutamic acid) (PGA) was grafted with amino acid and oligopeptide spacers up to 5 amino acids with the use of N,N'-carbonyldiimidazole and 2,3-dihydro-1,2-benz-isothiazole-3-on-1, 1-dioxide (saccharin) as an additive, and these polypeptides were

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 260-281, March/April 2026.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.
