Short term variations in atmospheric electric potential gradient

, 1969
Short term variations of electrical potential gradient (sometimes called 'agitation') have been studied during fair and disturbed weather and on days with and without wind.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

A method for improving the performance of gradient systems for diffusion-weighted MRI [PDF]

, 2007
The MR signal is sensitive to diffusion. This effect can be increased by the use of large, balanced bipolar gradients. The gradient systems of MR scanners are calibrated at installation and during regular servicing visits.

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Killing potentials with geodesic gradients on Kaehler surfaces [PDF]

Indiana University Mathematics Journal, 2012
We classify compact Kähler surfaces with nonconstant Killing potentials such that all integral curves of their gradients are reparametrized geodesics.

Soft motions encoded by the fold and mediated by conserved hinge sites drive V‐ATPase allosteric machinery and autoinhibition

FEBS Letters, EarlyView.
Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Drought Stress Increases the Complexity of the Bacterial Network in the Rhizosphere and Endosphere of Rice (Oryza sativa L.)

Agronomy
The root microbiota plays a crucial role in assisting the plant host in combating various biotic and abiotic stresses, notably drought, which poses a significant threat to global food security.

Potential Gradients in Anodic Films

Transactions of The Electrochemical Society, 1932
Potential gradients calculated for anodic films in electrolytic condensers will vary from 160,000,000 to 2,000,000 volts per centimeter, depending upon the film theory used in the calculations. The solid oxide theory results in potential gradients that reach 5,000,000 volts per centimeter as a maximum, but dielectric constants of approximately 30 are ...

On the Potential Function of Gradient Steady Ricci Solitons [PDF]

Journal of Geometric Analysis, 2011
A steady gradient Ricci soliton is a Riemannian manifold \((M,g)\) together with a real potential function \(f\) satisfying \(\text{Ric}+ \text{Hess\,}f= 0\). For a complete and noncompact \(M\), it is shown that the infimum of the potential function decays linearly. In particular it cannot be bounded unless it is constant.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
