Association of PET-measured myocardial flow reserve with echocardiography-estimated pulmonary artery systolic pressure in patients with hypertrophic cardiomyopathy [PDF]

open access: yes, 2019
BackgroundPulmonary hypertension (PH) is a known complication of HCM and is a strong predictor of mortality. We aim to investigate the relationship between microvascular dysfunction measured by quantitative PET and PH in HCM patients.MethodsEighty-nine ...

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors

open access: yesAdvanced Science, EarlyView.
Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

Neural mechanisms underlying the after-effects of repetitive paired-pulse TMS with β tACS on the human primary motor cortex

open access: yesScientific Reports
We previously reported that repetitive paired-pulse transcranial magnetic stimulation (TMS; rPPS) synchronized to the peak phase of transcranial alternating current stimulation (tACS) at the β frequency induced long-lasting after-effects on primary motor

Use of computer modeling to investigate a dynamic interaction problem in the Skylab TACS quad-valve package [PDF]

open access: yes, 1975
A valve opening-response problem encountered during development of a control valve for the Skylab thruster attitude control system (TACS) is described. The problem involved effects of dynamic interaction among valves in the quad-redundant valve package ...

After-effects of 10 Hz tACS over the prefrontal cortex on phonological word decisions

open access: yes, 2019
Introduction Previous work in the language domain has shown that 10 Hz rTMS of the left or right posterior inferior frontal gyrus (pIFG) in the prefrontal cortex impaired phonological decision-making, arguing for a causal contribution of the bilateral ...

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

open access: yesAdvanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

In vivo PET quantification of the dopamine transporter in rat brain with [¹⁸F]LBT-999. [PDF]

open access: yes, 2013
INTRODUCTION: We examined whether [(18)F]LBT-999 ((E)-N-(4-fluorobut-2-enyl)2β-carbomethoxy-3β-(4'-tolyl)nortropane) is an efficient positron emission tomography (PET) tracer for the quantification of the dopamine transporter (DAT) in the healthy rat ...

Astrocytic TIA1‐Mediated Stress Granules Promote the Demyelination of Optic Neuritis by Sequestering mRNA of Cholesterol Synthesis Genes in an Experimental Autoimmune Encephalomyelitis Model

open access: yesAdvanced Science, EarlyView.
Astrocytic TIA1‐mediated stress granules (SGs) promote demyelination by sequestering the mRNA of cholesterol synthesis genes. In this model, astrocytic TIA1‐mediated SGs were increased in the optic nerves of EAE mice, leading to the downregulation of cholesterol synthesis genes such as HMGCS1 through sequestration of their mRNA into SGs, which ...
