Intensity Calibration in the Presence of a Disturbing Effect Dependent on Wavelength [PDF]

Symposium - International Astronomical Union, 1994
Conversion of light detector signals to intensity values is one of the most important factors influencing precision of spectroscopic observations. Most of the classical light detectors used in astronomical practice are more or less nonlinear.

Disturbances of Sleep in the Intensive Care Unit

Critical Care Clinics, 1994
Sleep can be extremely difficult to achieve in ICUs. Sleep deprivation is a major problem in the ICU and physicians should be aware of the effects of sleep deprivation on physiologic and immune function. Sleep deprivation has been associated with the ICU syndrome.

Consequences of plateau pika disturbance on plant-soil carbon and nitrogen in alpine meadows

Frontiers in Plant Science
The presence of burrowing mammals can have extensive effects on plants and soils, creating bare soil patches in alpine meadows and potentially altering plant-soil carbon (C) and nitrogen (N). This study focuses on the plateau pika (Ochotona curzoniae) to

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Interoceptive Awareness Mediates Effects of Sleep Disturbance on Pain Outcomes in Chronic Pain Patients

Integrative Medicine Reports
Background: Sleep disorders are common in adults with chronic pain and are multifactorial. Recent evidence suggest sleep disturbance may affect interoceptive awareness (IA) in healthy adults.

Temporal effects of disturbance on community composition in simulated stage‐structured plant communities

Ecology and Evolution, 2018
In an era of global environmental change, understanding how disturbance affects the dynamics of ecological communities is crucial. However, few studies have theoretically explored the potential influence of disturbance including both intensity and ...

Coastal dynamic geomorphology under high intensity disturbance: research progress and perspectives

Shui kexue jinzhan, 2023
The coastal zone is the strongest interaction zone among the land, ocean, and atmosphere, and it is also the area that is most affected by global climate, sea-level change, and human activities.The dynamic process of the coastal zone has obvious ...
