Immunohistochemical distribution of surfactant apoprotein-A in congenital diaphragmatic hernia

Journal of Pediatric Surgery, 1997
Morphometric analyses of the immunohistochemical expression of surfactant apoprotein A (SP-A) were carried out on the bronchioles of human congenital diaphragmatic hernia (CDH) neonates and then compared with those in a gestational and postnatal age-matched control group.

Placental iron utilisation in fetal growth restriction: alterations in mitochondrial haem synthesis and iron–sulphur cluster assembly pathways

The Journal of Physiology, Volume 604, Issue 5, Page 2229-2249, 1 March 2026.
Abstract figure legend Altered iron handling and mitochondrial pathways in FGR placentas. Placental tissue from FGR pregnancies showed increased expression of iron importers, transferrin and divalent metal transporter 1, and decreased expression of the iron exporter ferroportin, suggesting that the FGR placenta is retaining iron to meet its own ...

Characterization of plasma lipoproteins of grain- and cholesterol-fed White Carneau and Show Racer pigeons.

Journal of Lipid Research, 1985
Plasma cholesterol concentrations from White Carneau (WC) and Show Racer (SR) pigeons consuming a cholesterol-free grain diet averaged about 300 mg/dl, approximately 200 mg/dl as high density lipoproteins (HDL) and the remainder as low density ...

Identification of putative methanol dehydrogenase (moxF) structural genes in methylotrophs and cloning of moxF genes from Methylococcus capsulatus bath and Methylomonas albus BG8 [PDF]

, 1988
An open-reading-frame fragment of a Methylobacterium sp. strain AM1 gene (moxF) encoding a portion of the methanol dehydrogenase structural protein has been used as a hybridization probe to detect similar sequences in a variety of methylotrophic bacteria.

High-Potential C112D/M121X (X = M, E, H, L) Pseudomonas aeruginosa Azurins [PDF]

, 2009
Site-directed mutagenesis of Pseudomonas aeruginosa azurin C112D at the M121 position has afforded a series of proteins with elevated Cu^(II/I) reduction potentials relative to the CuII aquo ion.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

FEBS Letters, Volume 600, Issue 4, Page 467-480, February 2026.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

The lecithin–cholesterol acyl transferase activity of rat intestinal lymph

Journal of Lipid Research, 1977
The lecithin-cholesterol acyl transferase (LCAT) activity in rat mesenteric lymph was examined as a possible source of chylomicron cholesteryl ester. Lymph activity was only 2–3% of rat serum activity.

Defining Resonance Raman Spectral Responses to Substrate Binding by Cytochrome P450 from \u3cem\u3ePseudomonas putida\u3c/em\u3e [PDF]

, 2008
Resonance Raman spectra are reported for substrate-free and camphor-bound cytochrome P450cam and its isotopically labeled analogues that have been reconstituted with protoheme derivatives that bear -CD3 groups at the 1, 3, 5, and 8-positions (d12 ...

Tyrosine 263 in Cyanobacterial Phytochrome Cph1 Optimizes Photochemistry at the prelumi-R→lumi-R Step [PDF]

, 2014
We report a low-temperature fluorescence spectroscopy study of the PAS-GAF-PHY sensory module of Cph1 phytochrome, its Y263F mutant (both with known 3D structures) as well as Y263H and Y263S to connect their photochemical parameters with intramolecular ...

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

Advanced Science, Volume 13, Issue 8, 9 February 2026.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...
