Peripheral blood CD4+ T cell counts are a key measure for assessing disease progression and need for antiretroviral therapy in HIV-infected patients. More recently, studies have demonstrated a dramatic depletion of mucosal CD4+ T cells during acute infection that is maintained during chronic pathogenic HIV as well as SIV infection. A different clinical disease course is observed during the infe...
in order to study on effect of magnetic field on germination characteristics and early growth of marigold (calendula officinalis l.) seeds an experiment was carried out in laboratory conditions in arak university of iran. seeds were magnetically exposed to magnetic field strengths, 100 or 200 mt for different periods of time; d1 (control), d2 (1 h), d3 (6 h), d4 (12h), d5 (24 h) and d6 (continu...
The increasing rate of water and air pollution dramatically impacts natural ecosystems human health causing depletion biodiversity, climate changes, spreading respiratory diseases, and, as a consequence, negatively impacting the world economy [...]
Failure to separate unexpected capital gains and losses on natural assets from depletion breaks the link between Net National Product (NNP) and sustainability. In addition, for resource rich countries this can lead to large spurious fluctuations in NNP, making it virtually useless for policy purposes. In contrast, when depletion is measured correctly, the link between NNP and sustainability is ...
The circular economy represents a fundamental pillar for modern business models and sustainable development targets: the mandatory claim “reduce, reuse, recycle” is answer to global criticalities of natural resources depletion waste increase [...]
