Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

open access: yesMolecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Poor expression of miR‐195‐5p can assist the diagnosis of cerebral vasospasm after subarachnoid hemorrhage and predict adverse outcomes

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Objective Patients with spontaneous subarachnoid hemorrhage (SAH) may develop refractory arterial cerebral vasospasm (CVS), which is the leading cause of death in SAH patients. This study explored the clinical diagnostic value of serum miR‐195‐5p levels in CVS after SAH (SAH + CVS) and its relationship with the prognosis of SAH + CVS.

Detection of spinning objects at oblique light incidence using the optical rotational Doppler effect.

open access: yesOptics Express, 2019
The optical rotational Doppler effect of light beams with angular momentum has recently found applications in the remote sensing of spinning objects. However, most of the reported experimental demonstrations rely on the particular condition of normal ...

Christian andreas doppler

open access: yesJournal of the Practice of Cardiovascular Sciences, 2019
CA Doppler described the doppler effect which was a shift in the frequency of light. This theory was later used for multiple applications in electromagnetics, astronomy, physics, aviation and health sciences.

Optimal nonlinear filtering of MPSK signals in the presence of a Doppler frequency shift

open access: yesРоссийский технологический журнал, 2022
Objectives. Phase-shift keyed (PSK) signals are widely used in many telecommunication, communication, and cellular information transmission systems. Phase-shift keying provides a higher noise immunity than amplitude and frequency modulations do.

Theoretical analysis and experimental verification on optical rotational Doppler effect. [PDF]

open access: yesOptics Express, 2016
We present a theoretical model to sufficiently investigate the optical rotational Doppler effect based on modal expansion method. We find that the frequency shift content is only determined by the surface of spinning object and the reduced Doppler shift ...

Cerebral autoregulation in patients with acute lacunar infarction: a reliable predictor of outcome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective To further investigate the association between dynamic cerebral autoregulation (dCA) and the outcomes in patients with acute lacunar infarction. Methods Patients were prospectively and consecutively enrolled at The First Hospital of Jilin University between 2016 and 2023. dCA was monitored at 1–3 and 7–10 days after the stroke.

ADCP Discharge Measurements on the River Danube: Post-Processing and Correction of Data

open access: yesSlovak Journal of Civil Engineering, 2019
Accurate measurements and analyses of river discharges are one of the key tasks of hydrology. Nowadays, the traditional methods of discharge measurements are being supplemented or even replaced by novel approaches that utilize state-of-the-art ...

Occurrence, Risk Factors, and Prognosis of Acute Cerebral Microinfarcts in CADASIL

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic cerebral small vessel disease in adults. This study investigates the occurrence, risk factors, and prognosis of acute cerebral microinfarcts (ACMIs) in patients with CADASIL.
