Prognostic value of p53 gene mutations in a large series of node-negative breast cancer patients
The most important subgroup of breast cancer patients for which reliable prognostic factors are needed are women without axillary lymph node involvement. Although overall, these patients have a good prognosis, it is known ...
Functional role of the noncatalytic domains of elongation factor tu in the interactions with ligands
Elongation factor (EF) Tu from Escherichia coli contains three domains, of which domain 1 (N-terminal domain) harbors the site for nucleotide binding and GTP hydrolysis. To analyze the function of domains 2 [middle (M) ...
Germline hMSH2 and hMLH1 gene mutations in incomplete HNPCC families
Hereditary non-polyposis colon cancer (HNPCC) is a common hereditary disease characterized by a predisposition to an early onset of colorectal cancer. The majority of the HNPCC families carry germline mutations of either ...
On the classification of the third reduction with a spectral value condition

Multiplex systems for the amplification of short tandem repeat loci: evaluation of laser fluorescence detection
Short tandem repeat (STR) loci are ideal markers for personal identification and for genomic mapping. Two fluorescent multiplex systems, each designed for simultaneous PCR amplification of four polymorphic STR loci (HUMCSF1PO, ...
Evaluation of chimerism with DNA polymorphisms in bone marrow transplantation
(International Children's Center (I C C), 1997)
Evaluation of chimeric status following allogenlc BMT is an Important tool for monitoring the replacement of host cells with donor cells and for determining the risk of relapse. Polymorphic DNA sequences can be used as ...
On the moduli space of real Enriques surfaces
We introduce a new invariant, Pontryagin-Viro form, of real algebraic surfaces. We evaluate it for real Enriques surfaces with non-negative minimal Euler characteristic of the components of the real part and prove that, ...
On convergence of attainability sets for controlled two-scale stochastic linear systems
(Society for Industrial and Applied Mathematics, 1997)
A limit of attainability sets is found for a linear two-scale stochastic system for the case when the diffusion coefficient of the fast variable is of order ε1/2. The attainability set is defined as the set of distributions ...
J-approximation of complex projective spaces by lens spaces
(Mathematical Sciences Publishers, 1999)
In this paper we study the group J(Lk(n)) of stable fibre homotopy classes of vector bundles over the lens space, Lk(n) = S2k+1/ℤn where ℤn is the cyclic group of order n. We establish the fundamental exact sequences and ...
Photoluminescence from a VCSEL structure a-SiNx:H microcavity
Microcavity effects on the photoluminescence (PL) of porous Si has already been reported. Recently, we have observed visible and near infrared (IR) PL from hydrogenated amorphous Si nitride (a-SiNx:H) grown by low temperature ...
