Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Effect of chemical mixing state on the hygroscopicity and cloud nucleation properties of calcium mineral dust particles [PDF]

Atmospheric Chemistry and Physics, 2009
Atmospheric mineral dust particles can alter cloud properties and thus climate by acting as cloud condensation nuclei (CCN) that form cloud droplets. The CCN activation properties of various calcium mineral dust particles were studied experimentally to ...

Re‐evaluation of sulphuric acid and its sodium, potassium, calcium and ammonium salts (E 513, 514 (i), 514 (ii), 515 (i), 515 (ii), 516 and 517) as food additive

EFSA Journal, 2019
The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re‐evaluating the safety of sulphuric acid (E 513) and its sodium (E 514), potassium (E 515), calcium (E 516) and ammonium (E 517) salts when used as a food additive.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Observations on the reaction calcium sulphate hemihydrate + water ↔ gypsum

, 1965
A study by microscopy was made of the dehydration and rehydration of grains and single crystals of gypsum. The results confirm the view that, although dehydration of gypsum may be topotactic, hydration of calcium sulphate hemihydrate is merely a matter ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Comparison Between Βiphasic Alloplastic ß-Tricalcium Phosphate in Calcium Sulphate Matrix and ß-Tricalcium Phosphate Bone Grafts in Immediate Implant Placement in Mandibular Molars [PDF]

Alexandria Dental Journal
Introduction: One of the primary challenges associated with immediate implant placement was the presence of a "jumping gap" between the implant fixture and the surrounding bone.
