A case-control study of 268 patients with CBP and 268 healthy workers matched by age and sex, all of whom were occupationally exposed to benzene, was conducted.
      
His earliest significant publication, "Tsargolod" ("The Tsar of Hunger"), introduced Marxist thought to Russian workers.
      
The concept of the chemical structure of glasses, as developed by Shultz and co-workers, is then examined in the light of neutron scattering studies of oxide systems.
      
The dynamics of the sympathoadrenal function and the specific features of heart rhythm regulation were studied in female students and clothing factory female workers during their adaptation to academic and work conditions.
      
In clean-up workers, somatosensory disorders were significantly associated with hypochondriac and schizophrenic-like symptoms.
      
Studies were performed in subjects with various circulatory disorders and in healthy subjects at rest and during exercise; in skilled and apprentice workers at an electronics plant; and in students under examination stress.
      
This process was proposed a long time ago by Kolotyrkin and co-workers, but their experimental results were subjected to serious criticism which is taken care of in the present paper.
      
Variation in Lymphocyte Sensitivity to the Antimutagenic Effect of Retinol in Workers Exposed to Nickel Compounds
      
Individual sensitivity to nickel compounds was studied in workers employed in nickel industry.
      
The mutagen sensitivity was inferred from the number of sister chromatid exchanges (SCEs), which was used to characterize the structural alterations of the chromosomes in workers' lymphocytes before and after administration of retinol for a month.
      
The SCE number decreased after retinol administration in nine out of eleven workers.
      
Some of the workers experienced combined irradiation from external and internal (incorporated plutonium-239) sources.
      
A Study of the Genetic Basis of Susceptibility to Occupational Fluorosis in Aluminum Industry Workers of Siberia
      
The phenotype frequency distributions of several classical blood genetic markers and dermatoglyphic characters were analyzed in workers of Siberian aluminum plants who had occupational fluorosis.
      
Comparison with healthy workers revealed significant differences in frequencies of several markers.
      
Polymorphism of Xenobiotic Metabolism Genes in Petrochemical Workers
      
Genetic polymorphism of xenobiotic metabolizing enzymes responsible for individual susceptibility to different environmental factors was examined in a cohort of petrochemical workers occupationally exposed to adverse action of chemical compounds.
      
The odds ratio of the disease development in the workers carrying heterozygous CYP1A1 mutant allele was 2.2.
      
Analysis of the GSTM1 gene polymorphism demonstrated a decrease in the frequency of the homozygous deletion carriers in the workers compared to the control group.
      
In addition, the odds ratio of the disease development for the workers with slow acetylator phenotype was 1.7.
