The main purpose of this study was to investigate the applicability of frequency domain analysis on laser Doppler flowmetry (LDF) data recorded from the index fingers of patients with carpal tunnel syndrome (CTS) and diabetic polyneuropathy (DPN). Patients with numbness of the palm were recruited and grouped according to the results of electrophysiological examinations into 2×2 groups by the ex...

We propose a motion-robust laser Doppler flowmetry (LDF) system that can be used as a non-contact blood perfusion sensor for medical diagnosis. Endoscopic LDF systems are typically limited in their usefulness in clinical contexts by the need for the natural organs to be immobilized, as serious motion artifacts due to the axial surface displacement can interfere with blood perfusion measurements...

Previous researchers have shown that there exists an interaction between gingival blood flow and gingival health. The purpose of this study was to compare the papillary blood flow at sites treated by a bridge with the blood flow at untreated sites. Twenty persons with resin-bonded fixed partial dentures were included in the study. The contralateral natural teeth of the site symmetrical to that ...

To test the hypothesis that cutaneous active vasodilation in heat stress is mediated by a redundant cholinergic cotransmitter system, we examined the effects of atropine on skin blood flow (SkBF) increases during heat stress in persons with (CF) and without cystic fibrosis (non-CF). Vasoactive intestinal peptide (VIP) has been implicated as a mediator of cutaneous vasodilation in heat stress. V...

BACKGROUD An important drawback of the traditional technique for harvesting latissimus dorsi (LD) myocutaneous flap is a long, posterior donor-site incision. Current techniques involve endoscopic or robotic harvesting via a combined approach of open and closed surgery, which necessitates an open axillary incision and the use of special retractors. In this paper, we introduce a fully enclosed la...

PURPOSE To assess the capability of the subfoveal choroidal circulation to regulate its blood flow in response to an acute increase in ocular perfusion pressure in the eyes of healthy elderly persons or of subjects with neovascular age-related macular degeneration (AMD). METHODS Changes of subfoveal choroidal blood velocity (ChBVel), volume (ChBVol), and flow (ChBF) induced by isometric exerc...

In this paper we focus on the differentiation and quantification of different heat mass transfer phenomena governing overall sorption dynamics, for example a binder-based aluminium fumarate (Alfum) coating transformation applications with water as refrigerant. The methodological emphasis is extending volume swing frequency response (FR) method to problems strong limitation. parameters are mappe...

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 ...

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 ...

AIMS To evaluate different algorithms used to analyse retinal nerve fibre layer thickness (RNFL) data obtained by scanning laser polarimetry, in order to compare their relative abilities to discriminate between patients with glaucomatous localised nerve fibre layer defects and normal subjects. METHODS 48 eyes of 48 glaucomatous patients with localised RNFL defects and 53 eyes of 53 healthy su...
