Field-domain rapid-scan EPR at 240GHz for studies of protein functional dynamics at room temperature.

We present field-domain rapid-scan (RS) electron paramagnetic resonance (EPR) at 8.6T and 240GHz. To enable this technique, we upgraded a home-built EPR spectrometer with an FPGA-enabled digitizer and real-time processing software.

Factors associated with neonatal sepsis among neonates admitted in Kibungo Referral Hospital, Rwanda.

More than one million neonatal deaths occur every year worldwide, of which 99% take place in low-income countries. In Rwanda, nearly 71% of neonatal deaths are preventable and among these, 10% are due to neonatal sepsis. Nevertheless, limited information exists on neonatal sepsis and its associated factors in Rwanda.

Routine Versus Selective Distal Perfusion Catheter Use in Venoarterial Extracorporeal Membrane Oxygenation.

Although current studies support the use of prophylactic distal perfusion catheters (DPCs) to decrease limb ischemia in patients on venoarterial extracorporeal membrane oxygenation (VA ECMO), methods for monitoring limb ischemia differ between studies. We evaluated the safety of a selective rather than prophylactic DPC strategy at a single center with a well-established protocol for limb ischemia monitoring. Distal perfusion catheters were placed selectively if there was evidence of hypoperfusion at any point until decannulation.

Spatial control of sensory adaptation modulates mechanosensing in .

Sensory signaling pathways use adaptation to dynamically respond to changes in their environment. Here, we report the mechanism of sensory adaptation in the Pil-Chp mechanosensory system, which the important human pathogen uses to sense mechanical stimuli during surface exploration. Using biochemistry, genetics, and cell biology, we discovered that the enzymes responsible for adaptation, a methyltransferase and a methylesterase, are segregated to opposing cell poles as explore surfaces.
