Comparison of full-text versus metadata searching in an institutional repository: Case study of the UNT Scholarly Works [PDF]

, 2015
Authors in the library science field disagree about the importance of using costly resources to create local metadata records, particularly for scholarly materials that have full-text search alternatives. At the University of North Texas (UNT) Libraries,

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

Advanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

Advanced Science, EarlyView.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

Autophagy Activators Normalize Aberrant Tau Proteostasis and Rescue Synapses in Human Familial Alzheimer's Disease iPSC‐Derived Cortical Organoids

Advanced Science, EarlyView.
A new cerebrocortical organoid model using isogenic hiPSCs with familial Alzheimer's mutations recapitulates key AD features, including amyloid‐beta and phospho‐Tau aggregation, neuronal hyperexcitability, and synapse loss. Single‐cell RNA‐seq reveals aberrant pathways in excitatory and inhibitory neurons.

Aberrant Splicing Signatures Underpin Oligodendrocyte Damage in ALS and Neuron Loss in FTD

Advanced Science, EarlyView.
Integrating bulk and single‐nucleus RNA‐seq from ALS and FTD patients, we revealed distinct cellular dysfunctions, with severe oligodendrocyte damage in ALS and pronounced neuron loss in FTD. We identified cell‐type‐specific aberrant splicing events as potential biomarkers with robust classification performance, some of which produce de novo peptides ...

Modeling the Temporal Nature of Human Behavior for Demographics Prediction

, 2017
Mobile phone metadata is increasingly used for humanitarian purposes in developing countries as traditional data is scarce. Basic demographic information is however often absent from mobile phone datasets, limiting the operational impact of the datasets.

Evolution of Multivalent Aptamer Corona for High‐Throughput Multiplexed Detection of Multiple Cancers

Advanced Science, EarlyView.
A multivalent aptamer corona is evolved via established ProteoFish‐SELEX (systematic evolution of ligands by exponential enrichment) for high‐throughput multiplexed detection of multiple cancers. Clinical validation using multivalent aptamer corona demonstrated high accuracy and specificity in multiplexed detection of ovarian, lung, and colorectal ...

Parallel Genome‐Wide CRISPR Screens Reveal SORL1 and ZFYVE19 as Sequential Host Determinants of Salmonella Infection

Advanced Science, EarlyView.
To distinguish how Salmonella invades cells vs how it survives long‐term, a parallel CRISPR screening platform is developed. This approach reveals the host proteins that the bacterium exploits at different stages of infection. The study identifies SORL1 as a novel host factor for invasion and demonstrates that blocking it with an antibody effectively ...

Observation Centric Sensor Data Model [PDF]

, 2010
Management of sensor data requires metadata to understand the semantics of observations. While e-science researchers have high demands on metadata, they are selective in entering metadata.
