Re-examining the potential effectiveness of interactive query expansion [PDF]

, 2003
Much attention has been paid to the relative effectiveness of interactive query expansion versus automatic query expansion. Although interactive query expansion has the potential to be an effective means of improving a search, in this paper we show that,

Expanding unilateral lung collapse using airway pressure release ventilation applied independently to the collapsed lung through the double-lumen endotracheal tube

Journal of Research in Medical Sciences, 2022
Unilateral lung collapse (ULC) is a clinical challenge in the intensive care unit and requires sophisticated treatment approaches, especially if the collapse continued over several hours.

Epithelial relaxation mediated by the myosin phosphatase regulator Mypt1 is required for brain ventricle lumen expansion and hindbrain morphogenesis [PDF]

Development, 2010
We demonstrate that in the zebrafish hindbrain, cell shape, rhombomere morphogenesis and, unexpectedly, brain ventricle lumen expansion depend on the contractile state of the neuroepithelium. The hindbrain neural tube opens in a specific sequence, with initial separation along the midline at rhombomere boundaries, subsequent openings within rhombomeres

Intracellular lumen extension requires ERM-1-dependent apical membrane expansion and AQP-8-mediated flux [PDF]

Nature Cell Biology, 2013
Many unicellular tubes such as capillaries form lumens intracellularly, a process that is not well understood. Here we show that the cortical membrane organizer ERM-1 is required to expand the intracellular apical/lumenal membrane and its actin undercoat during single-cell Caenorhabditis elegans excretory canal morphogenesis.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Abdominal aortic aneurysm classification based on dynamic intraluminal thrombus analysis during cardiac cycle

Journal of Vascular Surgery Cases and Innovative Techniques
The major complication of abdominal aortic aneurysm (AAA) is sudden rupture with an associated high mortality rate. The only clinical classifier for the risk of AAA rupture is the size of the aneurysm or its maximum diameter.

Claudin5a is required for proper inflation of Kupffer's vesicle lumen and organ laterality.

PLoS ONE, 2017
Left-right asymmetric organ development is critical to establish a proper body plan of vertebrates. In zebrafish, the Kupffer's vesicle (KV) is a fluid-filled sac which controls asymmetric organ development, and a properly inflated KV lumen by means of ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
