Correlations in survivin expression with the expression of p53 and bcl-2 in invasive ductal carcinoma of the breast.

This work studied the correlations between survivin, bcl-2 and p53 in infiltrating ductal carcinoma of the breast. A total number of 382 cases were collected from 3 hospitals in northeastern Malaysia. Survivin, bcl-2 and p53 were detected by immunohistochemistry on samples prepared from tissue blocks.

Survivin expression correlates with unfavourable prognoses in invasive ductal carcinoma of the breast.

Survivin is a 16.5-kDa intracellular protein also known as AP14 or BIRC5. It inhibits apoptosis and regulates cell division and belongs to the inhibitors of apoptosis (IAP) gene family.

The prevalence of human cytomegalovirus seropositivity among blood donors at the Unit of Blood Transfusion Medicine, Hospital Universiti Sains Malaysia.

Human cytomegalovirus (HCMV) is a species-specific DNA virus of the Herpetoviridae family. After a primary infection, HCMV persists in a latent form most probably in bone marrow progenitor cells or in peripheral blood monocytes. The virus can reactivate to result in shedding of the virus leading to virus dissemination and new infections.

The utilization of an index for serum globulin compensation in diseases associated with decreased serum albumin.

The albumin globulin ratio (A/G ratio) is meant to represent the ratio of alterations in serum proteins, since, in liver disease, globulins (G) rise following serum albumin (SA) decrease. pathophysiological value, its' use has been limited. Alternatively, we have developed an index, the globulin compensation index (GCI) to measure the changes in serum globulins when albumin is decreased.

Spectrometry and dosimetric evaluation of the gamma-ray emissions of 241Am.

New, detailed measurements have been made of the photon spectrum of the radionuclide 241Am. Observations, recorded for a 95% confidence level over local background, provide affirmation of a number of lines previously considered to be of equivocal existence. A number of hitherto unreported emissions are similarly observed.

Medically important solar ultraviolet A. Radiation measurements.

Results from a 6-year study of solar ultraviolet A (UVA) radiation measurements at the equatorial location of Penang (5 degrees N) are presented. On clear days, the diurnal flux reaches a very high dosage of about 3.0 x 10(-2) KWHM-2 around midday.
