PL2-01: Advances in staging

Is PL2 a Tractable Language?

It is believed by the scientific community that PL1 and PL2 are the largest concept languages for which there exists a polynomial algorithm that solves the subsumption problem. This is due to Donini, Lenzerini, Nardi, and Nutt, who have presented two tractable algorithms that are intended to solve the subsumption problem in those languages. In contrast, this paper proves that the algorithm for ...

Advances in the clinical staging of chronic lymphocytic leukemia.

Featured Article: Rai KR, Sawitsky A, Cronkite EP, Chanana AD, Levy RN, Pasternack BS. Clinical staging of chronic lymphocytic leukemia. Blood 1975;46:219 –34. Before publication of this article, clinicians treating chronic lymphocytic leukemia (CLL) experienced a high level of frustration because of the vast heterogeneity in the clinical courses of patients with CLL. After their initial diagno...

Frequencies of HLA-E*01:01/*01:03 Alleles in an Iranian Healthy Population and Its Comparison with Hyperglycemia Patients

Background and Aims: The human leukocyte antigen-E (HLA-E) is a member of non-classical HLA class-I genes which is highly conserved through evolution. In general, so far 25 alleles of HLA-E have been described. However, the existence of only two allelic group; HLA-E*01:01 and HLA-E*01:03 have been demonstrated in all the populations. HLA-E*01:01 and HLA-E*01:03 differ only at codon 107 of exon ...
