Asymptotic freedom in strong magnetic fields.

Perturbative gluon exchange interaction between quark and antiquark, or in a 3q system, is enhanced in a magnetic field and may cause vanishing of the total qq[over ¯] or 3q mass, and even unlimited decrease of it-recently called the magnetic collapse of QCD. The analysis of the one-loop correction below shows a considerable softening of this phenomenon due to qq[over ¯] loop contribution, similar to the Coulomb case of QED, leading to approximately logarithmic damping of gluon exchange interaction (≈O(1/ln|eB|)) at large magnetic field.

[Correlation between long-term proton pump ingibitor use, homocysteine and lipoproteins serum concentrations in patients with comorbidity of ischemic heart disease and acid peptic disease].

Present article is devoted to the study of the correlation between vitamin B12 serum level, hyperhomocysteinaemia and dyslipidemia. During research there were discovered that the lowest vitamin B12 serum level and the highest homocysteine serum level have been registrated in associated pathology (ischemic heart disease and acid peptic disease according to long-term proton pump inhibitor use) patients. It was shown evident correlation between that changes and dyslipidemia.

Therapeutic AIDS vaccines.

Therapeutic HIV vaccines represent promising strategy as an adjunct or alternative to current antiretroviral treatment options for HIV. Unlike prophylactic AIDS vaccines designed to prevent HIV infection, therapeutic vaccines are given to already infected individuals to help fight the disease by modulating their immune response. The first immunotherapeutic trial in AIDS patients was conducted in 1983.

Molecular epidemiology of the hepatitis C virus in Western Siberia.

Western Siberia is the region with little information on the prevalence of hepatitis C virus (HCV) infection, genotypic diversity of HCV isolates and risk factors. A molecular epidemiological survey was conducted to clarify these issues. Four groups of volunteers were included in a cross-sectional study (n = 500 in each group): health care workers; daycare patients from a hospital for drug users, daycare patients from an AIDS prevention and control center; and persons admitted to a local general practice clinic for any reason (outpatients).

"Exaggerated" natriuresis in experimental hypertension and the role of the natriuretic factor.

In rabbits with experimental ischaemic cerebral hypertension the role of the natriuretic factor in the genesis of the phenomenon of "exaggerated" natriuresis after extracellular space expansion was studied. In control animals an expansion of the extracellular fluid was followed by an elevation of the natriuretic factor in blood, whereas in hypertensive rabbits the phenomenon did not appear. Besides, in hypertensive rabbits the urinary excretion and the clearance of the natriuretic factor were considerably higher than in the control animals.
