Investigates the role of the tryptophanase C (tnaC)-tnaA spacer region and Rho factor in the expression of the tryptophanase operon of Proteus vulgaris. Examination of the expression in Escherichia coli; Incorporation of the deletions into a tnaA'-'lacZ reporter construct; Indications that the ...
Chinese forces had suddenly intervened in Korea en masse, and American marine and army units were forced into a precarious fighting retreat toward the port of Hungnam. The role of the Royal Marines, operating with attached American troops and transport as an ad hoc task force was now to move...
However, there is an argument that many species interactions are asymmetric, where one species unilaterally affects another species (amensalism or commensalism). This raises the unanswered question of what is the role of unilateral interactions in community dynamics. Here I use a theoretical approach...
The critical role of enzymes that regulate sialic acid in tumour cell growth and metastasis points towards targeting sialylation as a potential new anti-metastatic cancer treatment strategy. Herein, we explore insights into the mechanisms by which hypersialylation plays a role in promoting metastasis, ...
Looking at figures like gomastahs, chowdranies, and peons means we need to pay more attention to the agency and complexity of Indian subordinate staff during British colonisation. Following Bayly’s lead (1996), recent studies have examined the significant role of Indians agents working within th...
Among several candidate adaptivemutations, those in the tryptophanase regulator tnaC stand out, because the tna operon inwhich it resides has a known role in indole metabolism. One of the highly recombining populations also shows a significant excess of large-scale segmental DNA amplifications that ...

While the role and impact of international organizations (IOs) remains debated in international relations (IR) (Abbott & Snidal, 1998; Barnett & Finnemore, 2004; Gruber, 2000), there is a growing recognition that they formulate and adopt policy in a wide range of areas (Hooghe et al., ...
A clear pattern of host preference was observed for Anisakis spp. at cetacean family level: A. simplex (s.s.) and A. pegreffii infected mainly delphinids; A. physeteris and A. brevispiculata were present only in physeterids, and A. ziphidarum occurred in ziphiids. The role of ...
The present study was undertaken in order to systematically investigate the role of erythrocyte supplements during extended normothermic kidney perfusion with high perfusate oxygenation in both groups. By using a pressure-controlled model, an automatic adaptation of flowrates to the different viscosities...
