Riboswitches that couple binding of ligands to conformational changes offer sensors and control elements for RNA synthetic biology and medical biotechnology. However, design of these riboswitches has required expert intuition or software specialized to transcription or translation outputs; design has been particularly challenging for applications in which the riboswitch output cannot be amplified by other molecular machinery. We present a fully automated design method called RiboLogic for such 'stand-alone' riboswitches and test it via high-throughput experiments on 2,875 molecules using RNA-MaP (RNA on a massively parallel array) technology. These molecules consistently modulate their affinity to the MS2 bacteriophage coat protein upon binding of flavin mononucleotide, tryptophan, theophylline, and microRNA miR-208a, achieving activation ratios of up to 20 and significantly better performance than control designs. By encompassing a wide diversity of stand-alone switches and highly quantitative data, the resulting ribologic-solves experimental dataset provides a rich resource for further improvement of riboswitch models and design methods.

Riboswitches are cis-regulatory non-coding genomic segments that control the expression of downstream genes by undergoing conformational change upon ligand binding. We present a comprehensive database...
Since their discovery riboswitches have been attractive tools for the use-controlled regulation of gene expression in bacterial systems. Riboswitches facilitate small molecule mediated fine-tuning of ...
Medicinal chemistry and in particular "drug design" have often been perceived as more of an art than science. The many unknowns of human disease and the sheer complexity of chemical space render decis...
Standing up, sitting down and walking require considerable effort and coordination, which are crucial indicators to rehabilitation (e.g. stroke), and in older populations may indicate the onset of fra...
One of the many ways by which bacteria control gene expression is through cis-acting regulatory mRNA elements called riboswitches. By specifically binding to small molecules or metabolites and pairing...
The purpose of this study is to see if providing training using a Sit-to-Stand protocol for residents of Long-Term Care Facilities who have had a stroke will increase their independence in...
The study compares automated settings (Intellivent) with protocolized settings of the ventilator after cardiac surgery. The settings concern the respiratory rate, the inspiratory and expir...
A trial testing the efficacy of sit-stand workstations on decreasing sitting time and increasing light-intensity physical activity in samples of office worksites.
The purpose of this study is to investigate whether a device that allows office workers to sit or stand whilst working can reduce their sitting time at work and improve their health over 8...
The purpose of the expanded study is to examine the effectiveness of a "Stand Up and Move More" intervention to reduce sedentary behavior in older adults from underserved communities.
An approach, process, or methodology which emphasizes credible evidence and the best available scientific knowledge, judiciously integrated to achieve the best possible outcomes in structural design. For example, the design of a new OUTPATIENT CLINIC might incorporate a review of published research on outpatient clinic design, decisions on similar past projects, along with interviews with staff and consumers.
Architecture, exterior and interior design, and construction of facilities other than hospitals, e.g., dental schools, medical schools, ambulatory care clinics, and specified units of health care facilities. The concept also includes architecture, design, and construction of specialized contained, controlled, or closed research environments including those of space labs and stations.
The architecture, functional design, and construction of hospitals.
The art and science of designing buildings and structures. More generally, it is the design of the total built environment, including town planning, urban design, and landscape architecture.
A method of differentiating individuals based on the analysis of qualitative or quantitative biological traits or patterns. This process which has applications in forensics and identity theft prevention includes DNA profiles or DNA fingerprints, hand fingerprints, automated facial recognition, iris scan, hand geometry, retinal scan, vascular patterns, automated voice pattern recognition, and ultrasound of fingers.
