OBJECTIVES To report on the changes in fibrinolytic activity in human immunodeficiency virus (HIV) infected pregnant women who are undergoing highly active antiretroviral therapy (HAART). METHODS Blood was collected from 50 HIV positive women on HAART (test subjects), and 50 HIV positive women not on HAART (controls). These women were attending the prevention of mother to child clinic (PMTCT)...

The Notch signaling pathway is involved in a wide variety of cell-fate decisions during development. The diverse behavior of Notch-activated cells is thought to depend on tissue- or cell-type-specific transcription factors, yet the identities of such factors and the mechanism of cooperation with the Notch pathway are largely unknown. We identify here an enhancer in the promoter of ref-1, a C. e...

This paper argues that it would be useful for ergonomists and experienced English Language Teaching (ELT) professionals to collaborate as this would be of substantial interest to both sets of professionals. The ongoing debate in ELT on International English (IE) might usefully help to guide ergonomists if and when they require to judge that English is used at appropriately high levels in the wo...

The present study was an attempt to refine a qualitatively proposed model of ELT discipline-specific reading strategies to provide a better interpretation of qualitative findings. Hence, in line with the components of the previous model, that is, 6 factors and 32 categories, a 6-hypothetical factor and a 33-item questionnaire were considered in the design of the ELT discipline-specific question...

This paper develops a new approach to the adaptive line enhancement (ALE) of the emergency locator transmitter (ELT) signal where the input signal to the ALE is replaced by its autocorrelation function. This approach is related to the signal processing using Higher Order Statistics (HOS) of the signal recently introduced. The paper also compares the results of using the new approach with other ...
