BACKGROUND AND AIMS Human breast milk is an extremely dynamic fluid containing many biologically-active components which change throughout the feeding period and throughout the day. We designed a miRNA assay on minimized amounts of raw milk obtained from mothers of preterm infants. We investigated changes in miRNA expression within month 2 of lactation and then over the course of 24 hours. MA...

BACKGROUND/AIMS Viral infection during pregnancy is known to affect the fetal brain. The toll-like receptor (TLR)-3 is a pattern recognition receptor activated by viruses known to elicit adverse fetal neurological outcomes. The P-glycoprotein (P-gp) efflux transporter protects the developing fetus by limiting the transfer of substrates across both the placenta and the fetal blood-brain barrier ...

The sequence and structural selectivity of 15 different DNA binding agents was explored using a novel, thermodynamically rigorous, competition dialysis procedure. In the competition dialysis method, 13 different nucleic acid structures were dialyzed against a common ligand solution. More ligand accumulated in the dialysis tube containing the structural form with the highest ligand binding affin...

The application of photosensitizers for the treatment of fungal infections is a new and promising development within the field of photodynamic treatment (PDT). Dermatophytes, fungi that can cause infections of the skin, hair and nails, are able to feed on keratin. Superficial mycoses are probably the most prevalent of infectious diseases in all parts of the world. One of the most important rest...

Abstract BACKGROUND Macrophages can cross blood-brain-barrier (BBB) and infiltrate brain parenchyma with malignancies such as glioma. Recently, many efforts have been made to develop macrophage-based cancer therapy, including CAR–macrophages. However, lack of proliferation in differentiated macrophages hinders their utility. We sought ameliorate this problem by immortalizing assist potential th...

Numerous studies showing statistically significant associations between environmental noise and adverse health effects already exist for short-term (over one day at most) and long-term (over a year or more) noise exposure, both for morbidity and (albeit to a lesser extent) mortality. Recently, several studies have shown this association to be independent from confounders, mainly those of air po...

Two methods based on ion chromatography (IC) were developed for the detection of methyl and ethyl alkyl amines (methylamine (MA), ethylamine (EA), dimethylamine (DMA), diethylamine (DEA), trimethylamine (TMA) and triethylamine (TEA)) and NH(3)/NH(4)(+) in online atmospheric gas-particle and size-resolved particulate samples. The two IC methods were developed to analyze samples collected with an...

Electron transfer is an essential step in many important processes and has been the subject of intensive research, with relevance to areas such as molecular electronics, electrochemistry, biology, catalysis, information storage, and solarenergy conversion. Therefore, understanding interfacial electron transfer between molecules and electrodes, and their dynamics at the molecular level, is impor...

Free-base porphyrin (5,10,15,20-tetrakis(1-methyl-4-pyridyl)-21H,23H-porphine) (H(2)TMPyP4) has been shown to be an effective telomerase inhibitor by an in vitro assay. Here, we examined the interactions of the H(2)TMPyP4 with three distinct G-quadruplex DNAs, the parallel-stranded (TG(4)T)4, dimer-hairpin-folded (G(4)T(4)G(4))2, and monomer-folded AG(3)(T(2)AG(3))(3), by ultraviolet resonance ...
