Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Is nurse-measured blood pressure a valid substitute for ambulatory blood pressure monitoring?

open access: yes, 2000
BACKGROUND: Because ambulatory blood pressure monitoring (ABPM) is not available everywhere, the objective of the study was to determine whether nurse-measured blood pressure could be an acceptable substitute to ABPM.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Experimental investigation on mechanical properties and permeability evolution law of frozen calcareous clay under fluid-solid coupling

open access: yesCase Studies in Construction Materials
In the Huainan-Huaibei deep tundra mining project, groundwater seepage and complex geostress significantly challenge construction safety. To systematically investigate the mechanical properties and permeability evolution of frozen ground under coupled in-

An Experimental and Modeling Study on the Response to Varying Pore Pressure and Reservoir Fluids in the Morrow A Sandstone

open access: yesInternational Journal of Geophysics, 2012
In mature oil fields undergoing enhanced oil recovery methods, such as CO2 injection, monitoring the reservoir changes becomes important. To understand how reservoir changes influence compressional wave (P) and shear wave (S) velocities, we conducted ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Compositional, mechanical and transport properties of carbonate fault rocks and the seismic cycle in limestone terrains: A case study of surface exposures on the Longmenshan Fault, Sichuan, China [PDF]

open access: yes, 2015
Destructive earthquakes are common in tectonically active regions dominated by carbonate cover rocks. The catastrophic Wenchuan earthquake that struck Sichuan, China, also affected a section of carbonate cover terrain.
