On-line and real-time analysis of micro-organ activity permits to use the endogenous analytical power of cellular signal transduction algorithms as biosensors. We have developed here such a sensor using only a few pancreatic endocrine islets and the avoidance of transgenes or chemical probes reduces bias and procures general usage. Nutrient and hormone-induced changes in islet ion fluxes through channels provide the first integrative read-out of micro-organ activity. Using extracellular electrodes we captured this read-out non-invasively as slow potentials which reflect glucose concentration-dependent (3-15 mM) micro-organ activation and coupling...

Non Muscle Invasive Bladder Cancer (NMIBC) is among the most frequent malignant cancers worldwide. NMIBC is treated by transurethral resection of the bladder tumor (TURBT) and intravesical therapies, and has the highest recurrence rate among solid tumors. It requires a lifelong patient monitoring based on repeated cystoscopy and urinary cytology, both having drawbacks that include lack of sensitivity and specificity, invasiveness and care costs. We conducted an investigative clinical study to examine changes in the urinary metabolome of NMBIC patients before and after TURBT, as well during the subsequent surveillance period...

INTRODUCTION: Stereoelectroencephalography (sEEG) is a diagnostic procedure for patients with refractory focal epilepsies that is performed to localize and define the epileptogenic zone. In contrast to grid electrodes, sEEG electrodes are implanted using minimal invasive operation techniques without large craniotomies. Previous studies provided good evidence that sEEG implantation is a safe and effective procedure; however, complications in asymptomatic patients after explantation may be underreported...

BACKGROUND: The gold standard for bladder cancer detection is cystoscopy, which is an invasive procedure that causes discomfort in patients. The currently available non-invasive approaches either show limited sensitivity in low-grade tumours or possess unsatisfying specificity. The aim of the present study is to develop a new non-invasive strategy based on chromosomal imbalance levels to detect bladder cancer effectively. METHODS: We enrolled 74 patients diagnosed with bladder cancer (BC), 51 healthy participants and 27 patients who were diagnosed with non-malignant urinary disease (UD)...

BACKGROUND: Subjective data and physical examinations of patients after total hip arthroplasty are used to assess the outcome. But regarding the physical activity, no objective data can be delivered by existing scores. The level of activity can be measured objectively by counting gait cycles. The aim of this study was to measure activity levels of patients before and after total hip arthroplasty (THA). METHODS: Forty-six patients were included in this prospective study...

Although disease progression in Mucopolysaccharidosis I (MPS-1) can be attenuated by hematopoietic cell transplantation (HCT), it is increasingly recognized that residual disease is substantial. Biomarkers that would allow us to evaluate the efficacy of HCT (and upcoming new therapies) in non-hematological tissues are needed. Current biomarkers, including the iduronidase (IDUA) activity in leukocytes, are not suitable for this purpose as they are assessed in tissues of hematological origin and may not reflect enzyme availability in non-hematologic tissues...

Patients with eosinophilic esophagitis (EoE) require frequent evaluation of mucosal inflammation via endoscopy. Instead of endoscopy, mucosal evaluation in adults with esophageal cancer and candidiasis is achieved using a cytology brush inserted through a nasogastric tube (NGT). We conducted a prospective cross-sectional study in children and young adults scheduled for routine esophagogastroduodenoscopy (EGD) where in Phase 1, we performed esophageal brushing through the endoscope under direct visualization and in Phase 2, we inserted the brush through a Cortrak® NGT prior to endoscopy...

With the use of coordinated complex between aliphatic diols and calcium chloride (CaCl2) as green electrolytes, a body compatible, eco-friendly and low-cost thermometer is successfully developed. This particular conductive liquid possesses unique features of ultrafast response and high sensitivity against temperature change. The influences of CaCl2 concentra-tion and the category of aliphatic diols on conductivity change reveal that the thermal sensing abilities of such a kind of green electrolytes are positively relevant to the viscosity change along with temperature change...

A comprehensive monitoring of fitness, fatigue, and performance is crucial for understanding an athlete's individual responses to training to optimize the scheduling of training and recovery strategies. Resting and exercise-related heart rate measures have received growing interest in recent decades and are considered potentially useful within multivariate response monitoring, as they provide non-invasive and time-efficient insights into the status of the autonomic nervous system (ANS) and aerobic fitness. In team sports, the practical implementation of athlete monitoring systems poses a particular challenge due to the complex and multidimensional structure of game demands and player and team performance, as well as logistic reasons, such as the typically large number of players and busy training and competition schedules...

BACKGROUND: There is no accurate, non-invasive measurement to estimate the degree of pulmonary oedema in acute respiratory distress syndrome (ARDS). We developed the Radiographic Assessment of Lung Oedema (RALE) score to evaluate the extent and density of alveolar opacities on chest radiographs. After first comparing the RALE score to gravimetric assessment of pulmonary oedema in organ donors, we then evaluated the RALE score in patients with ARDS for its relationship to oxygenation and clinical outcomes...

OBJECTIVES: There are substantial potential benefits to noninvasive cardiac monitoring methods, such as electrical cardiometry (EC), over more invasive methods, including significantly reduced risk of complications, lower up-front and operational costs, ease of use, and continuous monitoring. To take advantage of these technologies, clinical equivalence to currently established methods must be determined. The authors sought to determine if the noninvasive measurement of cardiac index (CI) by EC was clinically equivalent to thermodilution (TD) in adult patients with aortic stenosis (AS)...

Amphotericin B (AMB) is a polyene macrolide antibiotic used for treating invasive fungal infections. Liposomal AMB (L-AMB) is a lipid dosage form which reduces the side effects and toxicity of the drug. The quantitation of free AMB (F-AMB) and L-AMB in vivo is important to monitor quality control of the liposomal formulation and to ensure its safety during clinical use. In this study, an original strategy was developed to separately determine F-AMB and L-AMB in rat plasma using LC-MS/MS. F-AMB was analyzed after separation by solid phase extraction, total AMB (T-AMB) was determined after protein precipitation and L-AMB was determined by difference...

Aims: Ablation of atrial fibrillation (AF) is recommended in the guidelines as a Class Ia/IIa indication. However, associated complications should not be dismissed; specifically, inguinal vascular complications (IVC). Although IVCs are generally considered trivial, they represent an economic burden for the procedure-performing hospital and the patient. Therefore, the ability to monitor and ultimately minimize potential complications is of considerable interest. Methods and results: An economic model was developed to calculate the economic impact for certain IVC-types from a large German single-centre perspective in 2015 and 2016...

Treatment of severe traumatic brain injury (TBI) in the intensive care unit focuses on controlling intracranial pressure, ensuring sufficient cerebral perfusion, and monitoring for secondary injuries. Yet there are limited prognostic tools and no biomarkers or tests of the evolving neuropathology. Metabolomics has the potential to be a powerful tool to indirectly monitor evolving dysfunctional metabolism. We compared metabolite levels in simultaneously collected arterial and jugular venous samples in acute TBI patients undergoing intensive care as well as in healthy control volunteers...

Circulating lycopene level is negatively associated with the prevalence of cardiovascular disease, cancers (prostate and breast), type 2 diabetes mellitus, and aging. Traditionally, lycopene is measured in biological specimens by a combination of high-performance liquid chromatography (HPLC) and mass spectrometry methods. Moreover, as we recently reported, tissue/cell lycopene depositions can be observed by the immunohistochemistry method with a newly developed monoclonal antibody (mAb) against lycopene. A main objective of this study is to evaluate the performance of a new noninvasive immunofluorescence (IF) lycopene quantification skin test with mAbs against lycopene versus HPLC lycopene assay of serum lycopene in volunteers subjected to lycopene supplementation and represents its novelty...

The active form of the small GTPase RAS binds to downstream effectors to promote cell growth and proliferation. RAS signal enhancement contributes to tumorigenesis, invasion, and metastasis in various different cancers. HRAS proto-oncogene GTPase (HRAS), one of the RAS isoforms, was the first human oncogene for which mutations were reported in T24 bladder cancer (BC) cells in 1982, and HRAS mutation or upregulation has been reported in several cancers. According to data from The Cancer Genome Atlas, HRAS expression was significantly upregulated in clinical BC samples compared to healthy samples (P=0...

Volatile organic compound (VOC) profiles emitted in trace concentrations from bacteria or cells has gained increasing importance over the last decades. Analysis of VOCs in the headspace does not interfere with in vitro systems and, therefore, offers new options for noninvasive monitoring of cultures. Currently there is not any available standardized in-vitro sampling system which considers effects of dilution and contamination onto ppbV to pptV VOC concentrations during. In this study a new in-vitro system for online and offline headspace measurement of biological cultures was designed...
