Computing Semantic Association: Comparing Spreading Activation and Spectral Association for Ontology Learning [PDF]

open access: yes, 2013
Spreading activation is a common method for searching semantic or neural networks, it iteratively propagates activation for one or more sources through a network { a process that is computationally intensive. Spectral association is a recent technique

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

Nitric oxide-induced activation of the AMP-activated protein kinase alpha2 subunit attenuates IKappaB kinase activity and inflammatory responses in endothelial cells [PDF]

open access: yes, 2011
Background: In endothelial cells, activation of the AMP-activated protein kinase (AMPK) has been linked with anti-inflammatory actions but the events downstream of kinase activation are not well understood.

Active voice, active writing [PDF]

open access: yesUbiquity, 2020
Each "Communication Corner" essay is self-contained; however, they build on each other. For best results, before reading this essay and doing the exercise, go to the first essay "How an Ugly Duckling Became a Swan," then read each succeeding essay. Knowing when to write in the active or passive voice can fundamentally improve your work, but ...

Abatacept for Prophylaxis of Acute and Chronic Graft‐Versus‐Host‐Disease in Children Undergoing Allogeneic Hematopoietic Stem Cell Transplantation—A Systematic Review and Meta‐Analysis of Cohort Studies

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Activation of hypoxia inducible factor 1 is a general phenomenon in infections with human pathogens [PDF]

open access: yes, 2010
Background: Hypoxia inducible factor (HIF)-1 is the key transcriptional factor involved in the adaptation process of cells and organisms to hypoxia. Recent findings suggest that HIF-1 plays also a crucial role in inflammatory and infectious diseases ...

Catalytic Asymmetric Synthesis of gem‐Dicyano‐Spirocyclopropyl Oxindoles by N‐9‐Anth‐PyBidine‐Co(OAc)2: Advantage of Three‐Component Coupling Approach

open access: yesChemistryEurope
A chiral N‐9‐Anth‐PyBidine‐Co(OAc)2 complex catalyzed the kinetically controlled asymmetric Michael/alkylation reaction of 3‐chlorooxindoles with alkylidenemalononitriles to give gem‐dicyano‐spirocyclopropyl oxindoles in a highly diastereo‐ and ...
