Ultra-weak photon emission (UPE) is a general feature of living -biological systems. To gain further insights into the origin of UPE and its physiological significance, the aim of the present study was to investigate the connection between hemodynamics (HD), oxygenation (OX), and UPE. Therefore, during venous and arterial occlusion (VO, AO), changes of UPE and surrogates of HD as well as OX wer...

Objective It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm22)), and the detection of such ultra-weak signals is hardly possi...

Urine protein electrophoresis (UPE) is often considered to have limited usefulness in evaluating proteinuria that is not associated with gammopathies. Unusual protein bands that are detected by UPE are commonly characterized by immunofixation electrophoresis (IFE). In this paper, electrophoretic gel patterns are shown to illustrate the greater sensitivity of IFE, compared to UPE. However, UPE r...

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due to acute myocardial infarction (AMI) without severe MR. The patient was successfully treate...

723 words): Background: Unplanned excision (UPE) is a common issue in soft tissue sarcoma treatment, but controversy still remains concerning its adverse effects on clinical outcomes. Some papers have reported even favorable patient survivals for UPE. However, different backgrounds should be considered because UPE tends to occur more often in superficial and small lesions. Residual tumor (ReT) ...

All biological samples emit ultra-low intensity light without any external stimulation. Recently, scientific communities have paid particular attention to this phenomenon, known as ultra-weak photon emission (UPE). UPE has been introduced in the literature as an alternative for biophoton, low-level chemiluminescence and ultra-weak bioluminescence, while it differs from ordinary bioluminescence,...

BACKGROUND The routine use of multidetector computed tomography has led to increased detection of unsuspected pulmonary embolism (UPE), with questionable benefit for diagnosis and treatment. OBJECTIVE The purpose of this work was to compare the clinical characteristics and prognosis of patients with UPE to patients with suspected PE (SPE). METHODS We retrospectively reviewed the charts of p...

BACKGROUND Cardiogenic unilateral pulmonary edema (UPE) is a rare entity, frequently leading to initial misdiagnosis. We sought to assess the prevalence of UPE and to determine its impact on prognosis compared with bilateral pulmonary edema. METHODS AND RESULTS We studied the characteristics and outcomes of patients admitted to our institution for cardiogenic pulmonary edema during an 8-year ...
