The abundance of salamanders in forest stands with different histories of disturbance
(Elsevier: Forest Ecology and Management, 1987-07)Because of the importance of salamanders in forest food chains, the effects of forest management practices on populations of these animals warrant consideration. We compared the numbers and activity patterns of salamanders ... -
Specializations of the body form and food habits of snakes
(Oxford University Press: American Zoologist, 1983)Viperid snakes have stouter bodies, larger heads, and longer jaws than snakes in other families; there are no major differences between the two subfamilies of vipers in these features. A suite of morphological characters ... -
ALFRED: the ALelle FREquency Database. Update
(Oxford University Press: Nucleic Acids Research, 2003-01-01)Elaboration of ALFRED (http://alfred.med.yale.edu) is being continued in two directions. One of which is developing tools for efficiently annotating the entries and checking the integrity of the data already in the database ... -
ALFRED: An allele frequency database for anthropology
(Wiley: American Journal of Physical Anthropology, 2002-09)The deluge of data from the human genome project (HGP) presents new opportunities for molecular anthropologists to study human variation through the promise of vast numbers of new polymorphisms (e.g., single nucleotide ... -
A global perspective on genetic variation at the ADH genes reveals unusual patterns of linkage disequilibrium and diversity
(University of Chicago Press: American Journal of Human Genetics, 2002-07)Variants of different Class I alcohol dehydrogenase (ADH) genes have been shown to be associated with an effect that is protective against alcoholism. Previous work from our laboratory has shown that the two sites showing ... -
The dependence of postreplication repair on uvrB in a recF mutant of Escherichia coli K-12
(Springer: Molecular and General Genetics, 1977-01)Summary Mutants carrying recF143 or recF144 show wild type levels of host cell reactivation of UV-irradiated lambda vir and wild type rates of excision gap closure in repairing UV damage to their own DNA. The same mutants ... -
W-reactivation of phage lambda in recF, recL, uvrA, and uvrB mutants of E. coli K-12
(Springer: Molecular and General Genetics, 1979-01)W-reactivation is reduced by recF143 and recF144 mutations and is undetectable if a second mutation at either the uvrA or uvrB locus is combined with recF143. The uvrA and uvrB mutations alone block W-reactivation partially. ... -
Defective excision and postreplication repair of UV-damaged DNA in a recL mutant strain of E. coli K-12
(Springer: Molecular and General Genetics, 1977-01)The mutation recL152 leads to a reduction of excision repair as measured by an increase in the time required to close uvrA uvrB dependent incision breaks, and by a reduction of host cell reactivation ability. Postreplication ... -
Evolution of Class-I MHC Genes and Proteins: From Natural Selection to Thymic Selection
(Annual Reviews: Annual Review of Immunology, 1990-04) -
The Pem homeobox gene: rapid evolution of the homeodomain, X chromosomal localization, and expression in reproductive tissue
(Elsevier: Genomics, 1996-06-15)A hallmark of homeobox genes is their high degree of sequence conservation in distantly related species. Here, we report the chromosomal localization, sequence, and expression pattern of an orphan homeobox gene,Pem,that ... -
Ancient HLA genes from 7,500-year-old archaeological remains
(Nature Publishing Group: Nature, 1991-02-28)In the past decade there has been increasing interest in cloning DNA from ancient and preserved tissues1−6. Most studies, however, have focused on mitochondrial or chloroplast genes, present at hundreds to thousands of ... -
Gene conversion in the evolution of the human and chimpanzee MHC class I loci.
(Blackwell: Tissue Antigens, 1991-10)Sixty-five DNA sequences from human and chimpanzee major histocompatibility complex class I loci were searched for statistical evidence of past gene conversion. Twenty-four potential conversions were detected; they were ... -
A transposable epitope of HLA-137, B40 molecules
(Springer: Immunogenetics, 1987-05)The monoclonal antibody M1340.2 defines a novel subtype of HLA-1340 that is expressed by the Sweig cell line. This molecule, called HLA-B40*, lacks an antigenic determinant that is common to HLA-137 and the HLA-Bw60 subtype ... -
Mhc-A locus molecules in pygmy chimpanzees: conservation of peptide pockets

The human leukocyte antigen TAP2 gene defines the centromeric limit of melanoma susceptibility on chromosome 6p.
(Blackwell: Tissue Antigens, 1996-02)A single human leukocyte antigen (HLA) class II allele, DQB1*0301, is strongly associated with melanoma, and the HLA-DR locus provides the telomeric boundary for melanoma susceptibility in the HLA class II region of ... -
Structure of CD8 alpha and beta chains of the orangutan: novel patterns of mRNA splicing encoding hingeless polypeptides

Identification of new TAP2 alleles in gorilla: evolution of the locus within hominoids
(Springer: Immunogenetics, 1996-06)Transporters associated with antigen processing molecules (TAP1 and TAP2) mediate the transfer of cytosolic peptides into the lumen of the endoplasmic reticulum for association with newly synthesized class I molecules of ... -
Domain organization and sequence relationship of killer cell inhibitory receptors
(Blackwell: Immunological Reviews, 1997-02)Natural killer (NK) cells recognize class I HLA molecules via a family of related receptors composed of two Or three Ig-like domains. Using neighbor-joining analysis of available sequences, groups of these receptors were ... -
Rapid direct determination of HLA-DQB1 * 0301 in the whole blood of normal individuals and cancer patients by specific polymerase chain reaction amplification
(Elsevier: Journal of ImmunologicalMethods, 1996)The HLA class II DQB1 * 0301 allele is present at a higher frequency in patients with malignant melanoma than in Caucasian controls. Furthermore, HLA-DQB1 * 0301 identifies a group of melanoma patients presenting with ... -
Transporter associated with antigen-processing-1 (TAP1) alleles in gorilla gorilla: diversification of the locus postspeciation
(Elsevier: Human Immunology, 1996-10)The transporter associated with antigenprocessing (TAP) proteins are required for the transport of cytosolic peptides into the endoplasmic reticulum for assembly with class I major histocompatibility molecules. In the rat, ...
