Stripe formation in bacterial systems with density-suppressed motility [PDF]
, 2012 Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of this process in a kinetic model that includes growth ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Clinical Chemistry, 2012 In 1947, Mandel and Metais discovered the unusual phenomenon of circulating cell-free DNA (1). Although one might naively think that DNA is found only in the nuclei of cells, it turns out that a substantial amount of small DNA fragments circulates within the blood.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

University of Western Ontario Medical Journal, 2020 Chromosomal disorders arise from errors in cell division and many are detected during prenatal development. Prenatal genomic screening techniques involve invasive methods such as chorionic villus sampling and amniocentesis. In this feature, current invasive techniques for genetic screening will be examined in relation to the development of non-invasive

How Much Do Downlink Pilots Improve Cell-Free Massive MIMO? [PDF]
, 2016 In this paper, we analyze the benefits of including downlink pilots in a cell-free massive MIMO system. We derive an approximate per-user achievable downlink rate for conjugate beamforming processing, which takes into account both uplink and downlink ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Community-acquired pneumonia in children: cell-free plasma sequencing for diagnosis and management. [PDF]
, 2019 Community-acquired pneumonia (CAP) is a common cause of pediatric hospital admission. Empiric antibiotic therapy for hospitalized children with serious CAP now targets the most likely pathogen(s), including those that may demonstrate significant ...

Downlink Power Control in User-Centric and Cell-Free Massive MIMO Wireless Networks
, 2017 Recently, the so-called cell-free Massive MIMO architecture has been introduced, wherein a very large number of distributed access points (APs) simultaneously and jointly serve a much smaller number of mobile stations (MSs).
