Indole test positive: appearance of pink layer at top (e.g. Escherichia coli) Like many biochemical tests on bacteria, results of an indole test are indicated by a change in color following a reaction with an added reagent. Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test.
HER2-positive breast cancer. Anaphylaxis, cardiac dysfunction and anaemia. Rituximab: IV: Anti-CD20 antibody. CD20-positive B cell non-Hodgkin lymphoma, chronic lymphocytic leukaemia, rheumatoid arthritis, granulomatosis with polyangiitis and microscopic polyangiitis
Most adjuvant breast cancer chemotherapy regimens do not routinely require growth factor support except for those associated with a high incidence of bone marrow suppression and infection. These may include chemotherapy given in the dose dense fashion i.e. 2-weekly instead of 3-weekly or TAC chemotherapy (see above). [10]
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
The A4 study on older individuals who are positive for indicators of AD but are negative for genetic risk factors will test Solanezumab in Phase III Clinical Trials, as a follow-up of previous Solanezumab studies. [26] DIAN-TU, launched in December 2012, focuses on young patients positive for genetic mutations that are risks for AD.
Also, IMViC is {+ + – -} for E. coli; as it is indole-positive (red ring) and methyl red-positive (bright red), but VP-negative (no change-colourless) and citrate-negative (no change-green colour). Tests for toxin production can use mammalian cells in tissue culture , which are rapidly killed by shiga toxin .
The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group.A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours.
Camptothecin (CPT) is a topoisomerase inhibitor.It was discovered in 1966 by M. E. Wall and M. C. Wani in systematic screening of natural products for anticancer drugs.It was isolated from the bark and stem of Camptotheca acuminata (Camptotheca, Happy tree), a tree native to China used in traditional Chinese medicine.
