Inverted Treaps

ACM Transactions on Information Systems, 2017
We introduce a new representation of the inverted index that performs faster ranked unions and intersections while using similar space. Our index is based on the treap data structure, which allows us to intersect/merge the document identifiers while simultaneously thresholding by frequency, instead of the costlier two-step classical processing methods.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Comparison of Vertical and Inverted-T Mammaplasties Using Photographic Measurements

Plastic and Reconstructive Surgery, Global Open, 2013
Background: Surgeons have long debated the relative merits of vertical and inverted-T mammaplasties. These debates have centered on surgeons’ opinions. Without measurements, this controversy is unlikely to be resolved.

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Ion Inverted‐V Precipitation Adjoining Auroral Arc: Low‐Altitude Observations With High Time/Space Resolution by the Reimei Microsatellite

Geophysical Research Letters
Previous studies have verified that upward geomagnetic field‐aligned electric fields (FAEFs) produce inverted‐V signatures of precipitating electrons that generate discrete auroras in upward field‐aligned currents (FACs).

Effect of Hoffman’s Exercise Versus Inverted Syringe Technique on Nipple Length and Breastfeeding Outcomes among Primiparous Women with Inverted Nipples. [PDF]

Egyptian Journal of Health Care
Background: First-time breastfeeding mothers with inverted nipples often encounter difficulties with breastfeeding due to insufficient infant latching resulting in inadequate milk extraction, maternal dissatisfaction, and unsatisfactory infant satiety ...

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

FEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...
