Evidence • The ALLHAT substudy1 (n = 19 731 with normal baseline K levels) found the following results at 1 year. -Overall, 3.5% of those taking chlorthalidone (12.5 to 25 mg), 0.2% of those taking lisinopril (10 to 40 mg), and 0.3% of those taking amlodipine (2.5 to 10 mg) had K levels less than 3.2 mmol/L; 1.2% of those taking chlorthalidone, 3.6% of those taking lisinopril, and 1.9% of those...

Drug resistance is a major obstacle for the successful treatment of many malignancies, including neuroblastoma, the most common extracranial solid tumor in childhood. Therefore, current attempts to improve the survival of neuroblastoma patients, as well as those with other cancers, largely depend on strategies to counter cancer cell drug resistance; hence, it is critical to understand the molec...

Until the mid-20th century, clinicians' concern was directed mainly to the systolic component of blood pressure. Later, however, when systolic blood pressure was found to be elevated with advancing age and decreased compliance of the arterial wall, it began to be considered an inevitable consequence of aging. Based on this belief, physicians often concluded that only the diastolic blood pressur...

High blood pressure is a well recognised major risk factor for cardiovascular disease, which is a primary cause of morbidity and mortality in patients aged 70 years or more. A number of studies including STOP-Hypertension-1, SHEP, and MRC II have shown that by lowering blood pressure in the elderly, cardiovascular morbidity and mortality can be significantly reduced. In fact, treatment of the e...

We previously reported that 3 p53 wild type (wt) MYCN amplified (MNA) neuroblastoma cell lines failed to G1 arrest after DNA damage despite induction of p53, p21(WAF1) and MDM2. We hypothesised that this was due to high MYCN expression. p53 responses to DNA damage were examined in an additional 13 p53 wt neuroblastoma cell lines. MNA was significantly associated with a failure to G1 arrest afte...
