Determining the Extent of Soil Degradation Processes Using Trend Analyses at a Regional Multispectral Scale

open access: yesLand, 2023
In order to ensure the sustainability of production from agricultural lands, the degradation processes surrounding the fertile land environment must be monitored.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Influence of U-shaped structure on upward flame spread and heat transfer behaviors of PMMA used in building thermal engineering

open access: yesCase Studies in Thermal Engineering, 2020
Both experimental and theoretical study on upward flame spread and heat transfer behaviors of PMMA (polymethyl methacrylate) under different U-shaped structure factors (Π) was conducted. The main results are as follows. The progress of pyrolysis front is

Groundwater Recharge Potentiality Mapping in Wadi Qena, Eastern Desert Basins of Egypt for Sustainable Agriculture Base Using Geomatics Approaches

open access: yesHydrology, 2023
In arid and hyper-arid areas, groundwater is a precious and rare resource. The need for water supply has grown over the past few decades as a result of population growth, urbanization, and agricultural endeavors.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Object spaces for safe image surgery [PDF]

open access: yesProceedings of the International Workshop on Smalltalk Technologies, 2009
Long-lived systems rely on reflective self-modification to evolve. Unfortunately, since such a system is at both ends of a causal loop, this means modifications that impact the reflective layer itself can be overly difficult to apply. This paper introduces ObjectSpaces, a reification of the familiar Smalltalk image as a first-class entity. By confining

(Un)Safe spaces

open access: yesPsychotherapy & Politics International, 2023
Clinical psychology is traditionally a profession that is dominated by White, socioeconomically middle-class women. It took worldwide protests, campaigns, and initiatives following the murder of George Floyd to convince the field of psychology to finally acknowledge and admit its historic and present role in the reproduction of institutional racism. As

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly
