A Forecast of the HIV Clinician Workforce Need in the United States: Results of a Quantitative National Survey.

There is a decreasing HIV care workforce in the United States, whereas the need for HIV care and prevention continues to increase. To better understand this issue, a quantitative, anonymous, one-time, self-administered survey was conducted. The survey was completed by 1,004 prescribing clinicians currently providing HIV-related health care.

Induced accumulation of oleanolic acid and ursolic acid in cell suspension cultures of Uncaria tomentosa.

Increasing sucrose from 20 to 50 g l(-1) in Uncaria tomentosa cell suspension cultures enhanced ursolic acid and oleanolic acid production from 129 +/- 61 to 553 +/- 193 microg g(-1) cell dry wt. The maximal concentration of both triterpenes (1680 +/- 39 microg g(-1) cell dry wt) was 8 days after elicitation by jasmonic acid, while yeast extract or citrus pectin treatments produced 1189 +/- 20 or 1120 +/- 26 microg g(-1) cell dry wt, respectively. The ratio of ursolic acid:oleanolic acid was constant at 70:30.
