The malaria parasite Plasmodium falciparum degrades hemoglobin in its acidic food vacuole for use as a major nutrient source. A novel metallopeptidase activity, falcilysin, was purified from food vacuoles and characterized. Falcilysin appears to function downstream of the aspartic proteases plasmepsins I and II and the cysteine protease falcipain in the hemoglobin proteolytic pathway. It is una...
We report here on the precise ability of mouse androgenetic embryos produced by in-vitro fertilization of enucleated oocytes to develop to day 9.5 of gestation when cultured with M16 and CZB media. Androgenetic embryos cultured with CZB rather than M16 medium developed to the blastocyst stage in a more significant proportion (56.6% versus 45.0%, P < 0.001). However, after cavitation, the rate o...
Minichromosome maintenance (MCM) proteins are essential DNA replication factors conserved among eukaryotes. MCMs cycle between chromatin bound and dissociated states during each cell cycle. Their absence on chromatin is thought to contribute to the inability of a G2 nucleus to replicate DNA. Passage through mitosis restores the ability of MCMs to bind chromatin and the ability to replicate DNA....
We present a search for water maser emission at 22 GHz associated with young low-mass protostars in six H ii regions —M16, M20, NGC 2264, NGC 6357, S125, and S140. The survey was conducted with the NRAO Very Large Array from 2000 to 2002. For several of these H ii regions, ours are the first high-resolution observations of water masers. We detected 16 water masers: eight in M16, four in M20, th...
BACKGROUND The permanent hearing loss following exposure to intense noise can be due either to mechanical structural damage (tearing) caused directly by the noise or to metabolic (biochemical) damage resulting from the elevated levels of free radicals released during transduction of the sound overstimulation. Drugs which depress active cochlear mechanics (e.g. furosemide and salicylic acid) or ...
In this study, a new series of 16 methyl salicylate derivatives bearing a piperazine moiety were synthesized and characterized. The in vivo anti-inflammatory activities of target compounds were investigated against xylol-induced ear edema and carrageenan-induced paw edema in mice. The results showed that all synthesized compounds exhibited potent anti-inflammatory activities. Especially, the an...
We study the effects of SO(10) D-terms on the allowed parameter space ( APS ) in models with t− b− τ and b− τ Yukawa unifiction. The former is allowed only for moderate values of the D-term, if very precise ( ≤ 5% ) unification is required. Next we constrain the parameter space by looking for different dangerous directions where the scalar potential may be unbounded from below ( UFB1 and UFB3 )...
Preimplantation mouse embryos exhibit growth at the blastocyst stage when there is a dramatic increase in protein content between days 4 and 5 after hCG treatment. This increse in protein synthesis requires the uptake of amino acids from the surrounding medium, but the consumption of individual amino acids present as a mixture has not been examined. We therefore measured the simultaneous deplet...
KAE609 [(1'R,3'S)-5,7'-dichloro-6'-fluoro-3'-methyl-2',3',4',9'-tetrahydrospiro[indoline-3,1'-pyridol[3,4-b]indol]-2-one] is a potent, fast-acting, schizonticidal agent in clinical development for the treatment of malaria. This study investigated the absorption, distribution, metabolism, and excretion of KAE609 after oral administration of [(14)C]KAE609 in healthy subjects. After oral administr...
Long-term response to within full-sib family selection for increased postweaning gain was evaluated in lines having different effective population sized (Ne) and selection intensities (i). Line designations were I4(4), I8(2), I16(2), M4(4), M8(2) and M16(2), where I and M indicate selection of the top 50% and 25%, respectively; 4, 8 and 16 represent the number of parental pairs per replicate an...
