Increase in vitamin B-12 during highly active antiretroviral therapy.
With great interest, we read the article by Remacha et al (1) in which they discussed a role for homocysteine as a marker for vitamin B-12 status in HIV-infected patients undergoing highly active antiretroviral therapy (HAART). Compared with patients not receiving such therapy, patients receiving HAART not only had higher CD4 and CD8 cell counts and leukocyte counts, they also had higher hemogl...
متن کاملBiologic effects of 1,25-dihydroxycholecalciferol (a highly active vitamin D metabolite) in acutely uremic rats.
The development of a vitamin D-resistant state in the course of renal failure may be responsible for reduced intestinal absorption of calcium and an impaired response of skeletal tissue. Moreover, the kidney has been shown to carry out the conversion of 25-hydroxycholecalciferol (25-OH-CC) to a highly biologically active metabolite, 1,25-dihydroxycholecalciferol (1,25-diOH-CC). In the present s...
متن کاملA highly active immobilized ribonuclease.
adapter (like that available from Sigma) could aid in processing many samples simultaneously. The time required for the whole process, from picking up the colony for lysis to visualization of the amplified product on agarose gel, is only about 4 h, saving time in routine analysis of mycobacteria. We found that this method yields genomic DNA from common Gram-positive and -negative bacteria also ...
متن کاملHighly active antiretroviral therapy
The purpose of the present study was to assess the relationship between the awareness of HAART, beliefs regarding transmission of HIV of persons taking HAART, norms associated with sexual risk behaviour, fear of HIV/AIDS, optimism of finding a cure or vaccine, and sexual behaviour in the general population of Sweden. A mail survey was sent to 4,000 randomly selected individuals aged 16-44 years...
متن کاملCopolymerization of ethylene with α-olefins over highly active supported Ziegler-Natta catalyst with vanadium active component
The new highly active supported vanadium-magnesium catalyst (VMC) has been studied in α-olefin (1-butene, 1-hexene)/ ethylene copolymerization in the presence of hydrogen. Data on the effect of α-olefin/ethylene ratio in copolymerization on the content of branchings in copolymers, kinetic profile, copolymer yield, molecular weight and molecular weight distribution of copolymers have been obtain...
