Dynamic thromboembolic left ventricular outflow tract obstruction after aggressive procoagulant treatment in hemorrhagic shock: a case report

Journal of Medical Case Reports, 2021
Background In cases of hypertrophic obstructive cardiomyopathy (HOCM), the systolic anterior motion of the mitral valve apparatus results in an obstruction of the left ventricular outflow tract (LVOT), which is known as the SAM [systolic anterior motion]

A simplified approach to quantitative coded aperture X-ray phase imaging [PDF]

, 2013
We recently demonstrated how quantitative X-ray phase contrast imaging may be performed with laboratory sources using the coded aperture technique. This technique required the knowledge of system parameters such as, for example, the source focal spot ...

Metabolic support of tumor-infiltrating regulatory T cells by lactic acid

Nature, 2020
Regulatory T (Treg) cells, although vital for immune homeostasis, also represent a major barrier to anti-cancer immunity, as the tumour microenvironment (TME) promotes the recruitment, differentiation and activity of these cells1,2.

Tumor hypoxia is associated with resistance to PD-1 blockade in squamous cell carcinoma of the head and neck

Journal for ImmunoTherapy of Cancer, 2021
The majority of patients with recurrent/metastatic squamous cell carcinoma of the head and neck (HNSCC) (R/M) do not benefit from anti-PD-1 therapy. Hypoxia induced immunosuppression may be a barrier to immunotherapy. Therefore, we examined the metabolic

Virtual edge illumination and one dimensional beam tracking for absorption, refraction, and scattering retrieval [PDF]

, 2014
We propose two different approaches to retrieve x-ray absorption, refraction, and scattering signals using a one dimensional scan and a high resolution detector.

Investigation of the performance of an optimised MicroCAT, a GEM and their combination by simulations and current measurements [PDF]

, 2003
A MicroCAT (Micro Compteur A Trous) structure which is used for avalanche charge multiplication in gas filled radiation detectors has been optimised with respect to maximum electron transparency and minimum ion feedback.

A mollified Ensemble Kalman filter

, 2010
It is well recognized that discontinuous analysis increments of sequential data assimilation systems, such as ensemble Kalman filters, might lead to spurious high frequency adjustment processes in the model dynamics.
