On the (α, β)-Metrics of Conformally Flat Type With Weakly Isotropic Scalar Curvature

Journal of Mathematics
This paper considers Matsumoto metrics of conformally flat type that have weakly isotropic scalar curvature and proves that they reduce to Riemannian metrics or locally Minkowski metrics. In this case, they have zero scalar curvature. Similar results are

Scalar curvature of definable CAT-spaces [PDF]

advg, 2003
For a compact connected set belonging to some \(o\)-minimal structure (e.g. a semialgebraic or subanalytic set) the author defined the notion of scalar curvature measure which shares many of the properties of the standard scalar curvature of Riemannian manifolds. Carrying on previous work [\textit{A. Bernig}, Adv. Geom. 2, 29-55 (2002; Zbl 1027.53041)]

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

On the role of the parity violating Hojman–Holst term in gravity theories

Physics Letters B
We study Parity Violating Gravity Theories whose gravitational Lagrangian is a generic function of the scalar curvature and the parity odd curvature pseudoscalar, commonly known as the Holst (or Hojmann) term.

Thermodynamic geometry of holographic superconductors

Physics Letters B, 2016
We obtain the thermodynamic geometry of a (2+1) dimensional strongly coupled quantum field theory at a finite temperature in a holographic setup, through the gauge/gravity correspondence.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...
