We report here results from 45 primate V4 visual cortical neurons to the preattentive presentations of seven different patterns located in two separate areas of the same receptive field and to combinations of the patterns in the two locations. For many neurons, we could not determine any clear relationship for the responses to two simultaneous stimuli. However, for a substantial fraction of the...

background: like several other parasites, teladorsagia circumcincta secretes or excretes urea, but nei-ther the rate of efflux nor the possible metabolic sources of the urea has been considered. methods: parasites were maintained by passage through sheep. urea efflux was measured using phe-nol/hypochlorite after treatment with urea aminohydrolase. the kinetics of creatine amidinohy-drolase and ...

• Multivariate extreme-value analysis is concerned with the extremes in a multivariate random sample, that is, points of which at least some components have exceptionally large values. Mathematical theory suggests the use of max-stable models for univariate and multivariate extremes. A comprehensive account is given of the various ways in which max-stable models are described. Furthermore, a co...

Heterodimerization of Max with the nuclear oncoprotein Myc and the differentiation-associated proteins Mad and Mxi1 enables these factors to bind E-box sites in DNA and control genes implicated in cell proliferation and differentiation. We show that in the PC12 pheochromocytoma tumor cell line, functional Max protein is not expressed because of the synthesis of a mutant max transcript. This tra...

We describe Mxi2, a human protein that interacts with Max protein, the heterodimeric partner of the Myc oncoprotein. Mxi2 encodes a 297-residue protein whose sequence indicates that it is related to extracellular signal-regulated kinases (ERK protein kinases). Mxi2 in yeast interacts with Max and with the C terminus of c-Myc. Mxi2 phosphorylates Max both in vitro and in vivo. The Mxi2 putative ...

The salivary protein maxadilan (MAX) is a vasodilator and immunomodulator from the sand fly vector of the protozoan parasite Leishmania chagasi. Vaccinating BALB/c mice with sand fly salivary gland extracts or with MAX protects the host against L. major infection. Because of the potential use of MAX in an anti-Leishmania vaccine, we characterized the vertebrate host IgG response to MAX in the p...

Max-E47 is a protein chimera generated from the fusion of the DNA-binding basic region of Max and the dimerization region of E47, both members of the basic region/helix-loop-helix (bHLH) superfamily of transcription factors. Like native Max, Max-E47 binds with high affinity and specificity to the E-box site, 5'-CACGTG, both in vivo and in vitro. We have determined the crystal structure of Max-E...
