Evaluation of upper limb superficial venous percussion as a sign of anatomical location and venous permeability. A comparative study of superficial venous percussion to ultrasound findings on non-renal patients and on chronic kidney disease patients. [PDF]

open access: yesPLoS One, 2019
An analytical cross-sectional study with 70 individuals divided into two groups. Group A consisted of 35 volunteers who were being preoperatively prepared for the construction of arteriovenous fistula. Group B consisted of 35 non-renal patients selected by convenience. Each participant underwent physical examination, including venous percussion, of the

Imaging Venous Transit Time and Blood-Brain Barrier Permeability of the Deep Brain. [PDF]

open access: yesMagn Reson Med
ABSTRACT Purpose Imaging of venous vessels with advanced pulse sequences allows the assessment of important hemodynamic parameters. Previous work has measured venous transit time (VTT) and blood–brain barrier (BBB) water permeability in cortical tissue.

Effectiveness of heparin versus 0.9% saline solution in maintaining the permeability of central venous catheters: a systematic review [PDF]

open access: yesRevista Da Escola De Enfermagem Da U S P, 2015
Abstract OBJECTIVE Determining which is the most effective solution (heparin flush compared to 0.9% saline flush) for reducing the risk of occlusions in central venous catheters (CVC) in adults. METHOD The systematic review followed the principles proposed by the Cochrane Handbook; critical analysis, extraction and synthesis of data were performed by

Clinical outcomes and plasma clot permeability and lysability in patients with venous thromboembolism on rivaroxaban: a cohort study. [PDF]

open access: yesPolish archives of internal medicine, 2019
Denser fibrin structure and impaired fibrinolysis reported in patients following venous thromboembolism (VTE) can predict recurrent VTE after cessation of anticoagulation.The aim of the study was to investigate whether the properties of fibrin clot may be useful in predicting adverse events in patients with VTE receiving rivaroxaban.In 132 patients ...

Permeability and distribution of nerve growth factor in the brain of neonatal rats by periphery venous injection in hypoxic-ischemic state

open access: yesSpringerPlus, 2016
To investigate the permeability of β-NGF through blood-brain-barrier (BBB) in neonatal and adult rats, and the spatial distribution of β-NGF in different brain regions in hypoxic-ischemic (HI) and normal neonatal rats.To investigate the overall permeability of β-NGF through BBB, β-NGF labeled with I125 was injected into adult rats, neonatal rats and HI

Aspirin-induced increase in intestinal paracellular permeability does not affect the levels of LPS in venous blood of healthy women

open access: yesInnate Immunity, 2014
The presence of subclinical levels of LPS from Gram-negative bacteria, also referred to as endotoxin, in the circulation may induce a pro-inflammatory immune response that leads to the development of obesity and insulin resistance. Recent data indicate that high-fat meals may elevate circulating levels of LPS.
