Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

open access: yes, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

Recent advances in understanding acute respiratory distress syndrome [version 1; referees: 2 approved]

open access: yesF1000Research, 2018
Acute respiratory distress syndrome (ARDS) is characterized by acute diffuse lung injury, which results in increased pulmonary vascular permeability and loss of aerated lung tissue. This causes bilateral opacity consistent with pulmonary edema, hypoxemia,

Fluids in ARDS: more pros than cons

open access: yesIntensive Care Medicine Experimental, 2020
In acute respiratory distress syndrome (ARDS), increased pulmonary vascular permeability makes the lung vulnerable to edema. The use of conservative as compared to liberal fluid strategies may increase the number of ventilator-free days and survival, as ...

Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

open access: yesAdvanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.

Paracrine Factor Local Gradient‐Generating System for Engineering Perfusable Vascularized Hepatocyte Tissues with Perfusion‐Induced Proliferation

open access: yesAdvanced Healthcare Materials, EarlyView.
A paracrine factor local gradient (PFLG)‐generating system enables microvessel penetration across 3D hepatocyte tissues. The resulting vascularized constructs recapitulate hepatic sinusoidal hepatocyte—endothelial contact architecture and enhance hepatic functions in vitro.

VENOUS THROMBOEMBOLISM IN RELATION TO OVARIAN HYPERSTIMULATION SYNDROME: AN APPROACH TO DETERMINING THE LOW-MOLECULAR-WEIGHT-HEPARIN DOSES AND ACTIVITY

open access: yesАкушерство, гинекология и репродукция, 2016
Ovarian hyperstimulation syndrome (OHSS) is a relatively common complication of ovarian stimulation. The pathophysiology of OHSS is characterised by increased capillary permeability.

多时相计算机断层扫描血管成像对缺血性卒中的应用研究进展 Application of Multiphase Computed Tomography Angiography in Diagnosis and Evaluation of Ischemic Stroke

open access: yesZhongguo cuzhong zazhi, 2019
【摘要】 多时相CTA(multiphase CTA,mCTA)作为一项新型颅内血管影像检查技术,可通过追踪造影剂的空间分布及时间变化动态观察动脉峰值期、静脉峰值期及静脉晚期3个不同时相颅内血管显影情况。其特征性影像——“斑点征”可显示不同时相血管管壁的通透性,评估血栓长度及血栓渗透性,并评估颅内侧支循环状态、病变区血管通透性及静脉溶栓效果。本文就mCTA在侧支循环评估、血管通透性检测及血栓渗透性、血栓长度的识别等方面的研究现状和进展进行综述。 【Abstract】 Multiphase CTA (

Enhanced Na\u3csup\u3e+\u3c/sup\u3e/H\u3csup\u3e+\u3c/sup\u3e Exchange During Ischemia and Reperfusion Impairs Mitochondrial Bioenergetics and Myocardial Function [PDF]

open access: yes, 2008
Inhibition of Na+/H+ exchange (NHE) during ischemia reduces cardiac injury due to reduced reverse mode Na+/Ca2+ exchange. We hypothesized that activating NHE-1 at buffer pH 8 during ischemia increases mitochondrial oxidation, Ca2+ overload, and reactive ...
