conclusions patients receiving a cpvb in addition to tpvb after ldf reconstruction experienced similar pain to those receiving tpvb alone. a larger, randomized clinical trial is warranted to fully determine the benefits of using cpvb in addition to tpvb for this procedure. results a total of 22 patients were included in this study (11-cpvb and 11-tpvb). the mean nrs pain score of cpvb patients ...

Significant efforts have been done in order to improve adsorption desalination systems by developing advanced adsorbents. Silica-supported ionic liquid (SIL) has recently proposed as a promising material for water due its relatively high capacity around 1 kgwater.kgSIL−1. Such achieved performance can be considered an initial cornerstone that requires further important additional data before re...

Introduction. As a result of the coronavirus infection (COVID-19) pandemic, almost 74.9 thousand people died pneumonia in Russia 2021. Community-acquired (CAP) is accompanied by systemic re­sponse body to inflammation lung tissue and disorder microhemocirculation. The method laser Doppler flowmetry (LDF) allows assessing general parameters microcirculatory bed determining state various factors ...

We have developed a new fiber-optic system that combines diffuse reflectance spectroscopy (DRS) and laser Doppler Flowmetry (LDF) for a multi-modal assessment of the microcirculation. Quantitative data is achieved with an inverse Monte Carlo algorithm based on an individually adaptive skin model. The output parameters are calculated from the model and given in absolute units: hemoglobin oxygen ...

Local cooling of nonglabrous skin without functional sympathetic nerves causes an initial vasodilation followed by vasoconstriction. To further characterize these responses to local cooling, we examined the importance of the rate of local cooling and the effect of nitric oxide synthase (NOS) inhibition in intact skin and in skin with vasoconstrictor function inhibited. Release of norepinephrine...

Introduction. One of the main open problems in classical statistical physics is the formulation and derivation of simple laws that determine macroscopic quantities in strongly interacting systems far from equilibrium. A broad class of nonequilibrium systems can be characterized by the presence of a macroscopic current. An important diagnostic tool of non-equilibrium behaviour is then provided b...

Inhalation anesthetics (e.g. isoflurane) are preferable for longitudinal fMRI experiments in the same animals. We previously implemented isoflurane anesthesia for rodent forepaw stimulation studies, and optimized the stimulus parameters with short stimuli (1-3-s long stimulation with ten electric pulses). These parameters, however, may not be applicable for long periods of stimulation because r...

The normalization constant of the lateral distribution function (LDF) of an extensive air shower is a monotonous (almost linear) increasing function of the energy of the primary. Therefore, the interpolated signal at some fixed distance from the core can be calibrated to estimate the energy of the shower. There is, somehow surprisingly, a reconstructed optimal distance, ropt, at which the effec...

Postocclusive reactive hyperemia (PORH) was evaluated in three healthy volunteers and in three patients with different etiologies and suffering from peripheral arterial occlusive disease (PAOD). Three noninvasive methods were used: transcutaneous oximetry (TcPO2), near-infrared spectroscopy (NIRS), and laser Doppler flowmetry (LDF). Changes in perfusion and oxygenation of tissue were measured o...

Laser Doppler Flowmetry (LDF) is a non-invasive method to estimate the blood perfusion in the microcirculation. The method was first introduced over 30 years ago and has undergone a continuous development since. This work presents a thorough theoretical framework of the technique. It is described in detail how the laser light interacts with the tissue and moving red blood cells, how the light f...
