LONDON -- The FTSE 100 (INDEX: ^FTSE) is still on the up this week, gaining 21 points today to reach 5,946 and improve on the nine-month high it reached yesterday. Mining shares have helped push the index upward today, with a number of share prices rising in line with commodities prices.

Individual constituents of the various FTSE indexes are doing well, too. Here are three whose prices are rising today.

IDOX (IDOX 0.64%)
Shares in software and services supplier IDOX gained another 4.7%, taking the price up about 90% over the past 12 months. Today's boost came from full-year results that saw adjusted pre-tax profits rise by 36% to 14.8 million pounds, based on a combination of "acquisitions, organic growth and international expansion."

Adjusted earnings per share came in 55% higher at 3.83 pence, and the full-year dividend was lifted by 13% to 0.675 pence per share -- only a 1.3% yield.

Senior (SNR -1.24%)
The share price recovery of engineer Senior continued today, with the price rising 3.3% to 208.5 pence after the firm's preclose trading update told us that profit expectations are in line with October's positive trading statement.

That suggests we'll be seeing earnings per share near the current 16.5 pence consensus, putting the shares on a price-to-earnings ratio of about 12. And we should see a dividend yield of about 2.2%. Senior shares are now up more than 25% over the past 12 months, despite a couple of dips along the way.

Scancell (SCLP -1.67%)
Scancell Holdings shares continued the strong run that has seen the price rise sevenfold in the past 12 months, today putting on 0.2% to reach 49 pence. The developer of therapeutic cancer vaccines, which last week got a nice lift from favorable trial results, was further boosted today by the news that it has gained approval from the Gene Therapy Advisory Committee and the Healthcare products Regulatory Agency for a higher-dose trial of the same vaccine, SCIB1. The trial will commence in the new year.
