Journal Article

Sequence and chromosomal location of the I-309 gene. Relationship to genes encoding a family of inflammatory cytokines.

TL;DR: The genomic organization is essentially identical to that found in the genes encoding the structurally similar proteins TCA-3, hJE/MCP-1, and mJE, strengthening the hypothesis that these genes are evolutionarily related.
Journal ArticleDOI

An analysis of tumor necrosis factor α gene polymorphisms and haplotypes with natural clearance of hepatitis C virus infection

TL;DR: Nine TNF SNPs were typed in a cohort of individuals with well-defined HCV outcomes and the common wild-type haplotype −863C/−308G was associated with viral persistence in black subjects, independent of linkage with human leukocyte antigen (HLA) alleles.
Journal ArticleDOI

Dispermic origin and clinical outcome of three complete hydatidiform moles with 46,XY karyotype☆

TL;DR: Levels of human chorionic gonadotropin decreased to normal spontaneously within a short time, indicating a benign course in these three cases of complete, classic hydatidiform mole with a 46,XY karyotype.
Journal ArticleDOI

THE α-GLYCEROPHOSPHATE CYCLE IN DROSOPHILA MELANOGASTER IV. Metabolic, Ultrastructural, and Adaptive Consequences of αGpdh-1 "Null" Mutations

TL;DR: There was a premature deterioration and atrophy of the ultrastructural integrity of flight muscle sarcosomes observed by electron microscopy in the "null" mutants, accompanied by premature mortality of the mutant heterozygotes.
