The synthesis, spectroscopic characterization, and X-ray crystal structure of the sodium salt of a new sulfonated water-soluble ligand, sodium 2-(2-pyridin-2-yl-ethylamino)-benzenesulfonate (L) are described. Compound L crystallizes in the centrosymmetric space group Pbcn, orthorhombic, a=31.930(13) A, b=7.153(3) A,c=14.193(6) A, alpha=90.00, beta=90.00, gamma=90.00, V=3220(2) A(3), Z=9. pi-pi ...

Patterns of HIV-1 protease inhibitor (PI) resistance-associated mutations (RAMs) and effects on PI susceptibility associated with the L76V mutation were studied in a large database. Of 20,501 sequences with ≥1 PI RAM, 3.2% contained L76V; L76V was alone in 0.04%. Common partner mutations included M46I, I54V, V82A, I84V, and L90M. L76V was associated with a 2- to 6-fold decrease in susceptibilit...

We discuss a problem posed by Bárány, Katchalski and Pach: if {Pi : i ∈ I} is a family of closed convex sets in R such that diam (⋂ i∈I Pi ) = 1 then there exist s 6 2n and i1, . . . , is ∈ I such that diam (Pi1 ∩ · · · ∩ Pis) 6 Cn, where Cn 6 c √ n for an absolute constant c > 0. We prove that this statement holds true with Cn 6 cn. All the previously known estimates for Cn were exponential or...

A digitizer-microcomputer combination was utilized to determine soybean seedling response to population densities of M. incognita (Mi) under varied environmental conditions. Plant age, temperature, soil texture, and initial Mi inoculum (Pi) influenced the pattern of shoot and root growth. Effects of Mi on plant top growth were evident on plants inoculated 2 days after seeding, but generally wer...

Two different forms of glucose 6-phosphate dehydrogenase (EC 1.1.1.49) have been purified from etiolated and green leaves, respectively, of 6-day maize (Zea mays L. cv Fronica) seedlings. The procedure includes an ammonium sulfate step, an ion exchange chromatography, and a second gel filtration in Sephadex G-200 in the presence of NADP(+) to take advantage of the corresponding molecular weight...

Toxoplasma gondii Korean isolate (KI-1) tachyzoites were inoculated intraduodenally to BALB/c mice using a silicon tube, and the course of infection and immune responses of mice were studied. Whereas control mice, that were infected intraperitoneally, died within day 7 post-infection (PI), the intraduodenally infected mice survived until day 9 PI (infection with 1 × 10(5) tachyzoites) or day 11...

Severe neutropenia and bone marrow (BM) morphologic abnormalities occur during experimentally induced primary infection with feline immunodeficiency virus (FIV), a lentivirus biologically similar to human immunodeficiency virus (HIV). To further characterize the mechanisms involved in this acute infection model of lentivirus-induced BM suppression, peripheral blood counts, histologic BM studies...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.
