Phosphorylation of CREB affects its binding to high and low affinity sites [PDF]

open access: yes, 1992
Cyclic AMP treatment of hepatoma cells leads to increased protein binding at the cyclic AMP response element (CRE) of the tyrosine aminotransferase (TAT) gene in vivo, as revealed by genomic footprinting, whereas no increase is observed at the CRE of the

Advances in Hybrid Icing and Frosting Protection Strategies for Optics, Lens, and Photonics in Cold Environments Using Thin‐Film Acoustic Waves

open access: yesAdvanced Engineering Materials, EarlyView.
This article provides a comprehensive overview of fundamentals and recent advances of transparent thin‐film surface acoustic wave technologies on glass substrates for monitoring and prevention/elimination of fog, ice, and frost. Fogging, icing, or frosting on optical lenses, optics/photonics, windshields, vehicle/airplane windows, and solar panel ...

Acquired platelet dysfunction and overproduction of platelet cyclic AMP in two patients with myeloid malignancies

open access: yesPlatelets, 2019
The pathophysiology of impaired platelet function in acquired disorders is often poorly understood. We report two unrelated patients with hematologic malignancies associated with acquired severe bleeding diathesis, and complex platelet function ...

A Simple Derivation of AMP and its State Evolution via First-Order Cancellation [PDF]

open access: yes, 2019
We consider the linear regression problem, where the goal is to recover the vector $\boldsymbol{x}\in\mathbb{R}^n$ from measurements $\boldsymbol{y}=\boldsymbol{A}\boldsymbol{x}+\boldsymbol{w}\in\mathbb{R}^m$ under known matrix $\boldsymbol{A}$ and unknown noise $\boldsymbol{w}$. For large i.i.d.

Decreased Accumulation of Cyclic Adenosine 3′,5′-Monophosphate in “Ischemic” Skin after 12-0-Tetradecanoyl-phorbol-13-acetate Treatment [PDF]

open access: yes, 1982
The effect of 12-0-tetradecanoyl-phorbol-13-acetate (TPA) on cyclic adenosine 3′,5′-monophosphate (cyclic AMP) level in adult mouse skin in response to ischemia was examined.

Activation of hormone-sensitive lipase in extracts of adipose tissue

open access: yesJournal of Lipid Research, 1970
Rat adipose tissue was homogenized in 0.154 m KCI, and the supernatant fluid, obtained after centrifugation at 15,000 g, was extracted with benzene to remove triglycerides. Most of the lipase activity in the extracted fluid was precipitated with ammonium

Approximate Message Passing with Spectral Initialization for Generalized Linear Models [PDF]

open access: yesarXiv, 2020
We consider the problem of estimating a signal from measurements obtained via a generalized linear model. We focus on estimators based on approximate message passing (AMP), a family of iterative algorithms with many appealing features: the performance of AMP in the high-dimensional limit can be succinctly characterized under suitable model assumptions;

Low‐Activation Compositionally Complex Alloys for Advanced Nuclear Applications—A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐activation compositionally complex alloys (LACCAs) are advanced metallic materials primarily composed of low‐activation elements, offering advantages such as rapid compliance with operational standards and safe recyclability. This review highlights their potential for extreme high‐temperature irradiation environments as structural materials for ...

Ultrasonic controllable synthesis of sulfur-functionalized metal–organic frameworks (S-MOFs) and their application in piezo-photocatalytic rapid reduction of hexavalent chromium (Cr)

open access: yesUltrasonics Sonochemistry
The United Nations’ Sustainable Development Goals (SDGs) are significant in guiding modern scientific research. In recent years, scholars have paid much attention to MOFs materials as green materials.
