Habitat fragmentation and degradation seriously threaten native animal communities. We studied the response of a small marsupial, the agile antechinus Antechinus agilis, to several environmental variables in anthropogenically fragmented Eucalyptus forest in south-east Australia. Agile antechinus were captured more in microhabitats dominated by woody debris than in other microhabitats. Relative ...

Recently, hammerhead ribozyme (HHR) motifs have been utilized as powerful tools for gene regulation. Here we present a novel design of expanded full-length HHRs that allows attaching additional functionalities to the ribozyme. These features allowed us to construct a very efficient artificial riboswitch in bacteria. Following the design of naturally occurring three-way junctions we attached an ...

Synthetic biology approaches often combine natural building blocks to generate new cellular activities. Here, we make use of two RNA elements to design a regulatory device with novel functionality. The system is based on a hammerhead ribozyme (HHR) that cleaves itself to generate a liberated ribosome-binding site and, thus, permits expression of a downstream gene. We connected a temperature-res...

Chromosomal translocations in acute leukemia that affect the AML-1/CBFbeta transcription factor complex create dominant inhibitory proteins. However, the mechanisms by which these proteins act remain obscure. Here we demonstrate that the multidrug resistance 1 (MDR-1) promoter is a target for AML/ETO transcriptional repression. This repression is of basal, not activated, expression from the MDR...

BACKGROUND The prevalence of gastroesophageal reflux disease (GERD) and/or hiatal hernia (HH) is significantly increased in morbidly obese patients. Laparoscopic bariatric procedures such as gastric banding (LGB) and Roux-en-Y gastric bypass have been shown to improve both obesity and reflux symptoms. The aim of this paper is to evaluate the effectiveness of laparoscopic sleeve gastrectomy (LSG...

Abstract Usually, social order is defined by the animal size, live weight, or age. This study aimed to evaluate association among horn presence (HP), and size (HS) on rank hierarchy. Adult Dorper rams (n=24) with similar weight (LW), body condition score (BCS), age (AG) were subjected a behavioral test define success index (SI, ranked form 0 1) based male-to-male interactions, determining three...

A competency-based approach to health human resources (HHR) planning is one that explicitly considers the spectrum of knowledge, skills and judgement (competencies) required for the health workforce based on the health needs of the relevant population in some specific circumstances. Such an approach is of particular benefit to planners challenged to make optimal use of limited HHR as it allows ...

Educational institutions have largely failed to provide innovative responses to emerging health human resources (HHR) needs. Reasons include the prevailing ratio policy, which simply increases the supply of professionals; university funding protocols; a guild structure that isolates health professions rather than integrating them; and current credentialing for entry to practice, which both cont...
