IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

TRANSCENDING THE TRAJECTORY OF CYCLICAL IMPASSE: IN SEARCH OF A NEW BEGINNING IN ESIABA IROBI’S NWOKEDI [PDF]

open access: yesDiversitate si Identitate Culturala in Europa, 2013
Arguably, Nigeria’s transition from the military regime to the democratic rule in 1999 only marginally altered its political context dramatically. Nevertheless, corruption and mismanagement of her economic potential portentously remain her abiding ...

Rethinking the role of top-down attention in vision: effects attributable to a lossy representation in peripheral vision

open access: yesFrontiers in Psychology, 2012
Common wisdom in the field of human vision suggests that top-down selective attention is required in order to bind features into objects. Without selective attention, presumably we are unable even to distinguish such simple stimuli as a rotated T vs.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Moving towards Adaptive Search [PDF]

open access: yes, 2009
Information retrieval has become very popular over the last decade with the advent of the Web. Nevertheless, searching on the Web is very different to searching on smaller, often more structured collections such as intranets and digital libraries.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Search conversion journeys and the missed opportunity of associated keywords

open access: yesFrontiers in Communication
We map the conversion journey (i.e., the path a costumer takes to purchase a product or service) for phones, laptops, and vehicles (i.e., cars and trucks) by analyzing a massive corpus of online searches on Bing by people in the U.S. during 2021. We show

COMPUTER SEARCH VERSUS TECHNICAL-SCIENTIFIC FINDING [PDF]

open access: yesChallenges of the Knowledge Society, 2018
The study intends to establish delimitation between computer search and technical-scientific finding, having as a starting point certain cases encountered in the judicial practice when the law enforcement authorities confused the scopes of these two ...

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.
