The first life was believed to emerge in the early Earth via a process involving synthesis of organic compounds and formation protocells. However, it is still puzzle how protocell with hierarchal structure desirable functions spontaneously generated non-living environment composed mainly water minerals. In this work, using muscovite as an example minerals, we systemically studied coacervation p...

The purpose of this study was to investigate clinical outcomes following stereotactic body radiotherapy (SBRT) for lung metastases as oligo-recurrence. From May 2003 to June 2014, records for 66 patients with 76 oligo-recurrences in the lungs treated with SBRT were retrospectively reviewed. Oligo-recurrence primary sites and patient numbers were as follows: lungs, 31; colorectal, 13; head and n...

This paper reports a study of the adsorption of four proteins-fibrinogen, lysozyme, pyruvate kinase, and RNAse A-to self-assembled monolayers (SAMs) on gold. The SAMs examined were derived from thiols of the structure HS(CH2)loR, where R was CH3, CHzOH, and oligo(ethy1eneoxide). Monolayers that contained a sufficiently large mole fraction of alkanethiolate groups terminated in oligo(ethy1eneoxi...

antisense oligodeoxynucleotides (oligos) are the tools that bind to complemen¬tary sequence of targeted mrna and block specifically protein translation. in the present study, a novel 20 mer oligo as an antisense for human il-13 is introduced. this oligo is designed according to the il-13 mrna coding region and synthesized in two hplc purified and fitc conjugated forms. fluorescence oligo cell u...

A maize zein cDNA clone was used to synthesize mRNA with the SP6 in vitro transcription system. Although we obtained full-length transcripts of the cDNA sequence, these were inefficient templates for protein synthesis. Removal of the 5' oligo(G) sequence that was synthesized during the cDNA cloning procedure allowed efficient translation of the mRNAs in a wheat germ cell-free protein synthesis ...

The resonances of the imino protons and all of the non-exchangeable protons (except for H5'/H5'') of d(CGCAAAAAAGCG)d(CGCTTTTTTGCG) have been assigned by means of one- and two-dimensional NMR spectroscopies. Qualitative analyses showed that the overall structure is of the B-form, but local conformational deviations exist. The NOEs between the imino protons of thymines and H2 of adenines suggest...

A capacitive DNA-sensor model system was used to monitor the capture of complementary single-stranded DNAs. The sensor chip consisted of a gold electrode, which was carefully insulated with a polytyramine layer and covalently tagged with 25-mer oligo-C. As low as 10-11 moles per liter of target oligo-G could be detected by injecting 250 μL of sample. Elevated temperature was used to reduce non-...

The genome of human immunodeficiency virus (HIV) and especially the envelope gene are mutated with unusually high frequency during in vivo replication. Recent studies indicate that HIV reverse transcriptase (RT) is unusually error prone and that the number of generated mutations is disproportionately high within repetitive base sequences. To study the ability of recombinant and wild-type HIV RT...

Previous studies have shown that the action of bacterial or synthetic oligodeoxynucleotide (oligo-DNA) on mouse NK cells to produce IFN-gamma is mediated mostly by monocytes/macrophages activated by olig-DNA. However, its action on human IFN-gamma-producing cells has not been well investigated. In the present study, we examined the effect of oligo-DNAs on highly purified human NK and T cells. B...

1 An intrathecal (i.t.) injection of a selective d2-opioid receptor agonist, [D-Ala]deltorphin II, produced an acute antinociceptive tolerance to the antinociceptive e€ect of a subsequent i.t. challenge of [DAla]deltorphin II. This acute tolerance lasted 3 to 9 h and completely subsided by 12 h. The experiments were designed to examine the e€ect of pretreatment with an antisense oligodeoxynucle...
