Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

Advanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.

Non-cuffed dual lumen catheters in the external jugular veins versus other central veins for hemodialysis patients

Saudi Journal of Kidney Diseases and Transplantation, 2009
To compare prospective between insertion of non-cuffed dual lumen catheter in the external jugular vein and other central veins for hemodialysis (HD), we studied 68 chronic dialysis patients randomly allocated into two groups: one with external jugular ...

Cerebral venous thrombosis in a patient with Crohn's disease [PDF]

Intestinal Research, 2016
Patients with inflammatory bowel disease (IBD) have an elevated risk of venous thromboembolism compared with the general population. The most common sites of venous thromboembolism in IBD patients are the deep veins of the legs, the pulmonary system, and

Anatomic Diagram as a Novel Assessment Strategy for Subclinical Local Residual Disease in Sinonasal Squamous Cell Carcinoma and Intestinal‐type Adenocarcinoma

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Objective In the last two decades, transnasal endoscopic surgery (TES) has become pivotal in the management of sinonasal tumors. This approach involves a multiblock tumor resection, adding complexity to the interpretation of surgical margins after pathological examination.

Characterization of di‐gital, tri‐gital, and tetra‐gital temporal movement of systolic blood pressure on the arterial pulse waveform of rats at different vascular stiffness

Animal Models and Experimental Medicine, EarlyView.
The example of the time dependent fluctuation of systolic pressure on rat arterial pulse waveform in ms. The four levels of the systolic pressure fluctuation show di‐gital, tri‐gital and tetra‐gital fluctuation. The red dots represent particular heartbeats. Abstract Background An arterial stiffness is an indicator of many cardiovascular diseases.
