So far, many promoters have been isolated and used to drive the expression of foreign gene in the mammary gland. However, none of these promoters were specific and the expression in the mammary gland tissue was associated with expression in other tissues. The need for discriminating sequences, which can drive the expression of foreign gene specifically in the mammary gland, is obvious. This stu...

T he SALL genes, similar to the Drosophila gene spalt, probably encode zinc-finger transcription factors. In humans, four such genes have been identified to date. Mutations at SALL1 on chromosome 16q12.1 have been associated with Townes-Brocks syndrome and related phenotypes, 3 and mutations at SALL4 have been shown to be causative in patients with Okihiro/Duane-radial ray syndrome (OMIM No 607...

This article presents the attitude of ESP learners towards the role of Self-Access Language Learning Centres in improving their reading comprehension. It provides an evaluation of the success of these contents as well as an interpretation of students’ understanding of the related concepts. Finally it identifies factors that enhance or hinder the successful implementation of Self-Access Language...

was leaf gas exchange. The basis of the N2 fixation tolerance to water deficit in the eight selected PI lines is Nitrogen fixation in soybean (Glycine max Merr.) is especially not known. sensitive to soil drying. The basis of this sensitivity appears to be related to the fact that ureides are transported from the nodules, Recent studies have focused on ureide accumulation and the ureide concent...

The PNM2mutation of Saccharomyces cereuisiaeeliminates the extrachromosomal element 9. PNM2 is closely linked to the omnipotent suppressor gene SUP35 (also previously identified as SUP2, SUFl2, SAL3 and G S T l ) . We cloned PNM2and showed that PNM2 and SUP35 are the same gene. We sequenced the P N M Z mutant allele and found a single G --f A transition within the N-terminal domain of the prote...

Dengue virus (DENV) exists in both sylvatic and urban/ endemic ecotypes (15), and the potential for emergence of sylvatic strains has become a focus of research. Recently Mota and Rico-Hesse (10) attempted to evaluate the pathogenic potential of viruses belonging to different genetic subgroups of DENV serotype 2 (DENV-2). Based on the viremia levels and erythema index profiles of one sylvatic g...

We determined sites in X ell mRNA that are cleaved by RNase III in the presence of X OOP antisense RNA, using a series of OOP RNAs with different internal deletions. In OOP RNA-cll mRNA structures containing a potential region of continuous double-stranded RNA bounded by a non-complementary unpaired region, RNase III cleaved the ell mRNA at one or more preferred sites located 10 to 14 bases fro...
