Assessing the Impact of Lichens on Saint Simeon Church, Paşabağ Valley (Cappadocia, Turkey): Potential Damaging Effects versus Protection from Rainfall and Winds

Applied Sciences
The impact of lichens on the conservation of monuments, such as the World Heritage Site (WHS) of Cappadocian churches, presents a multifaceted challenge for conservators. Previous studies have shown that lichens can both induce deterioration processes of

Development of sustainable georesources for the built environment in the United Kingdom [PDF]

Estonian Journal of Earth Sciences, 2008
The character of the UK’s built heritage has been largely determined by the country’s diverse geology. Indigenous natural stone forms a major component of the nation’s pre-1919 building stock.

A Metabolic‐Epigenetic Axis of AARS1/IGF2BP3‐K280 Lactylation Sustains Endometrial Cancer Stemness and Recurrence

Advanced Science, EarlyView.
Lactate‐driven endometrial cancer relapse is mediated by enzymatic protein modification. Elevated lactate levels activate AARS1, which catalyzes K280 lactylation of IGF2BP3, therefore stabilizing HMGA2 mRNA and promoting tumor stemness and recurrence.

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

Advanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Mitochondrial Localization of Cx26 Promotes Colorectal Cancer Malignancy and Exposes a Fatal Vulnerability to Drug Targeting

Advanced Science, EarlyView.
Mitochondrial localization of Cx26 emerges as a double‐edged sword in colorectal cancer. PIMT‐mediated methylation of Cx26 promotes its mitochondrial localization and stability. Mitochondrial Cx26 then facilitates ER‐mitochondria communication and Ca2+ signaling, thereby promoting metastatic progression. Bortezomib exploits this malignant adaptation by

Study on the Applicability of Deterioration Detection Techniques for Sandstone Heritage in Multi Environment using MLP-Attention Model [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Stone cultural heritage, encompassing a broad spectrum of artifacts such as stone artworks, buildings, tools, and utensils, represents one of the most significant categories of cultural heritage. However, the conservation of these cultural heritage faces

Laboratory studies for stone conservation at the Cathedral of Murcia

Materiales de Construcción, 1990
The results of a series of laboratory tests, carried out on the bioclastic limestone used in the construction of the Murcia cathedral, are presented in this paper in order to evaluate the efficiency of certain treatment products, that eventually could be applied to that stone for improving their state of conservation.

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

Advanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

Practical Computational Exploration of Chemical Reaction Space: Assessing the Chemical Stability of Active Pharmaceutical Ingredients Under Acidic Conditions

Angewandte Chemie, EarlyView.
Metadynamics simulations drive automated reaction exploration of acid‐catalysed drug degradation, generating a network spanning 1720 species and 2471 elementary steps. QM‐based filtering reduces the network to eight candidate pathways for rigorous DFT refinement and microkinetic modelling.
