Custard pudding gels were prepared from fresh whole egg, milk and sugar. The effects of D-psicose (Psi), a non-calorie rare hexose, on the antioxidative activity and rheological properties of the custard pudding gels were investigated at different temperatures for comparison with those of control sugars (sucrose, Suc; D-fructose, Fru). The rheological behavior of the heat-induced pudding gels w...

In oxygenic photosynthetic organisms the PSI-C polypeptide, encoded by the psaC gene, provides the ligands for two [4Fe-4S] centers, FA and FB, the terminal electron acceptors in the photosystem I (PSI) complex. An insertion mutation introduced in the psaC locus of the filamentous cyanobacterium Anabaena variabilis ATCC 29413 resulted in the creation of a mutant strain, T398-1, that lacks the P...

OBJECTIVES/HYPOTHESIS This study assessed the long-term efficacy and recurrence rates of percutaneous steroid injections (PSIs) for benign vocal fold lesions. STUDY DESIGN Prospective clinical study. METHODS A prospective human clinical trial was performed from October 2008 to September 2014 at Soonchunhyang University Hospital, Bucheon, Korea. Percutaneous steroid injection was performed i...

The intricate assembly of photosystem I (PSI), a large multiprotein complex in the thylakoid membrane, depends on auxiliary protein factors. One of the essential assembly factors for PSI is encoded by ycf3 (hypothetical chloroplast reading frame number 3) in the chloroplast genome of algae and higher plants. To identify novel factors involved in PSI assembly, we constructed an epitope-tagged ve...

Electron microscope preparations were made of specimens of Actinosphaerium nucleofilum fixed in glutaraldehyde before, during, and after exposure to high pressures (4,000 to 8,000 psi). A study of this material showed that, although other organelles were relatively stable, the microtubular elements of the axopodia and cytosome became unstable under pressure. Their rapid disintegration under pre...

Pressure-volume curves and shoot water potentials were determined for black spruce (Picea mariana (Mill.) BSP) trees from four full-sib families at the Petawawa Research Forest, Ontario, Canada. Trees were sampled from a dry site in 1992 and from the dry site and a wet site in 1993. Modulus of elasticity (epsilon), osmotic potential at turgor loss point (Psi(tlp)) and relative water at turgor l...

In this paper, results on preparation of stable and uniform SERS solid substrates using macroporous silicon (pSi) with deposited silver and gold are presented. Macroporous silicon is produced by anodisation of p-type silicon in hydrofluoric acid. The as prepared pSi is then used as a template for Ag and Au depositions. The noble metals were deposited in three different ways: by immersion in sil...

When cells undergo nuclear apoptosis (chromatin condensation, DNA fragmentation), they already manifest at least three alterations that can be quantified cytofluorometrically at the single-cell level: 1) a loss of mitochondrial transmembrane potential (delta psi m), 2) an increased production of superoxide anions, and 3) the aberrant exposure of phosphatidylserine (PS) residues on the outer pla...
