Optimizing root yield of cassava under fertigation and the masked effect of atmospheric temperature.

Background: Fertigation is a rare and an expensive method of fertilizer application to cassava, and hence there is a need to optimize its efficiency for profitability. This study's objective was to optimize root yield of cassava through fertigation using a logistic model.

Results: The field treatments were six fertigation concentrations against three cassava varieties, selected according to their maturity period.

Transcriptome analysis reveals a dynamic and differential transcriptional response to sulforaphane in normal and prostate cancer cells and suggests a role for Sp1 in chemoprevention.

Scope: Epidemiological studies provide evidence that consumption of cruciferous vegetables, like broccoli, can reduce the risk of cancer development. Sulforaphane (SFN) is a phytochemical derived from cruciferous vegetables that induces anti-proliferative and pro-apoptotic responses in prostate cancer cells, but not in normal prostate cells. The mechanisms responsible for this cancer-specific cytotoxicity remain unclear.

Proof-of-concept rare cancers in drug development: the case for rhabdomyosarcoma.

Rare diseases typically affect fewer than 200,000 patients annually, yet because thousands of rare diseases exist, the cumulative impact is millions of patients worldwide. Every form of childhood cancer qualifies as a rare disease-including the childhood muscle cancer, rhabdomyosarcoma (RMS). The next few years promise to be an exceptionally good era of opportunity for public-private collaboration for rare and childhood cancers.

3,3'-Diindolylmethane, but not indole-3-carbinol, inhibits histone deacetylase activity in prostate cancer cells.

Increased consumption of cruciferous vegetables is associated with a reduced risk of developing prostate cancer. Indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) are phytochemicals derived from cruciferous vegetables that have shown promise in inhibiting prostate cancer in experimental models. Histone deacetylase (HDAC) inhibition is an emerging target for cancer prevention and therapy.

Alkylation of cyclomalto-oligosaccharides (cyclodextrins) with dialkyl sulfate-barium hydroxide: heterogeneity of products and the marked effect of the size of the macrocycle.

The alkylation of cyclomalto-oligosaccharides (cyclodextrins, CDs) with dialkyl sulfate-barium hydroxide has been claimed to yield 2,6-di-O-alkyl derivatives. Re-investigation by plasma desorption-m.s.

Effect of helium-oxygen mixture on myocardiac mitochondria of the rat.

Ultrastructural and stereological analysis of mitochondria of myocardiac cells from rats was performed after 2-hour breathing of helium-oxygen mixture. The following changes were observed in the cells of experimental animals as compared with the control ones: swelling of mitochondria, increase of the mean volume fraction of these structures and decrease of axial ratio of mitochondria.

Effect of breathing an oxygen-helium mixture under positive pressure on biochemical parameters.

In 35 subjects the effect of breathing an oxygen-helium mixture or oxygen during 10 minutes under positive pressure of 40 hPa was studied. Immediately before positive-pressure breathing, in the last minute of this breathing, and 30 minutes after its and blood samples were taken for investigations. Positive-pressure breathing caused in both groups a rise-in the haematocrit value, total protein, albumin and glucose levels.
