Optical Sensor System for 3D Jones Matrix Reconstruction of Optical Anisotropy Maps of Self-Assembled Polycrystalline Soft Matter Films.

Our work uses a polarization matrix formalism to analyze and algorithmically represent optical anisotropy by open dehydration of blood plasma films. Analytical relations for Jones matrix reconstruction of optical birefringence maps of protein crystal networks of dehydrated biofluid films are found. A technique for 3D step-by-step measurement of the distributions of the elements of the Jones matrix or Jones matrix images (JMI) of the optically birefringent structure of blood plasma films (BPF) has been created.

Multispectral High Temperature Thermography.

The paper considers the issues of creating high-temperature digital thermographs based on RGB photodetector arrays. It has been shown that increasing the reliability of temperature measurement of bodies with unknown spectral coefficient of thermal radiation can be ensured by optimal selection of the used spectral range and registration of the observed thermal radiation fields in three spectral ranges. The registration of thermal radiation in four or more spectral ranges was found to be inefficient due to the increasing error in temperature determination.

Utilization of Thromboelastogram and Inflammatory Markers in the Management of Hypercoagulable State in Patients with COVID-19 Requiring ECMO Support.

The role of extracorporeal membrane oxygenation (ECMO) in the management of critically ill patients with COVID-19 is evolving. Extracorporeal support independently confers an increased predilection for thrombosis, which can be exacerbated by COVID-19-associated coagulopathy. We present the successful management of a hypercoagulable state in two patients who required venovenous ECMO for the treatment of COVID-19.

Biphosphonate-induced osteonecrosis of the jaws: CT and MRI spectrum of findings in 32 patients.

Aim: To evaluate the computed tomography (CT) and magnetic resonance imaging (MRI) findings of biphosphonate therapy-associated changes of the mandible and maxilla.

Materials And Methods: Thirty-two patients with a clinical history of pain, purulent discharge, and swelling in the mandible or maxilla as well as non-healing dental extraction were examined. All patients had received biphosphonate medication for approximately 33 months.

A potential role for Dkk-1 in the pathogenesis of osteosarcoma predicts novel diagnostic and treatment strategies.

Canonical Wnt signalling is an osteoinductive signal that promotes bone repair through acceleration of osteogenic differentiation by progenitors. Dkk-1 is a secreted inhibitor of canonical Wnt signalling and thus inhibits osteogenesis. To examine a potential osteoinhibitory role of Dkk-1 in osteosarcoma (OS), we measured serum Dkk-1 in paediatric patients with OS (median age, 13.
