In Vitro Anti-Proliferation/Cytotoxic Activity of Epingaione and its Derivatives on the Human SHSY5Y Neuroblastoma and TE-671 Sarcoma cells

Epingaione (4-Methyl-1-(5-methyl-2,3,4,5-tetrahydro-[2,3’]bifuranyl-5-yl)-pentan-2-one) was isolated as one of the major lipophilic secondary metabolites from the leaves and stems of Bontia daphnoides L. The compound gave 79.24% and 50.83% anti-proliferation/cytotoxic activity on the human SH-SY5Y neuroblastoma and TE-671 sarcoma cells in vitro at 50 μg/mL, respectively. Epingaione was transformed into eleven derivatives under laboratory conditions using ethanol, some gave greater anti-proliferation/cytotoxic activity on the cancer cell lines tested.

Evaluation and Management of Hypertension in the Elderly

Issue:

Vol 61, Issue 9 (2012)

DOI:

10.7727/wimj.2012.063

Pages:

907–11

Synopsis:

Screening for elevated blood pressure in the elderly is recommended, since the prevalence of hypertension increases with age, and can reduce the incidence of morbidity and mortality. A careful and individualized approach is needed when treating hypertension in the elderly, taking into account the presence of co-morbid diseases, drug interaction, side effects, lifestyle and functional state.

The Prevalence and Significance of Oestrogen Receptor (ER) Positivity in Breast Cancer at the University Hospital of the West Indies, Jamaica

Issue:

Vol 61, Issue 8 (2012)

DOI:

10.7727/wimj.2012.121

Pages:

795–801

Synopsis:

Oestrogen receptor (ER) status was positive in 125 (63%) and negative in 74 (37%) patients diagnosed with breast cancer. By comparing the cohorts of ER negative to ER positive patients, one can accurately identify which clinical variables bear clinical significance in this population and are affected by ER status, as well as impact patient outcome.

ABSTRACT

Objective: To identify the prevalence of oestrogen receptor (ER) positivity, and determine the relationship of ER status with patient and tumour characteristics, in patients with breast cancer.
