PURPOSE: Although capnography is considered the gold standard for monitoring of ventilation, it may not work accurately in some situations. We compared the performance of two non-invasive continuous respiratory rate (RR) monitors that are alternatives for the detection of respiratory depression. METHODS: Fifty healthy volunteers ≥20 years old were enrolled in this study. After monitoring of the volunteers was started by the Masimo Radical-7(®) and Nellcor™ PM1000N, they breathed at the rate of 12 breaths/min for 3 min and then stopped breathing...

The odour pollution occurring in the initial decomposition stage of municipal solid waste (MSW), including collection, transfer and transportation, has not been sufficiently emphasised. Thus the emission characteristics of and variation in odorant generation in this stage were investigated through simulation experiments at different temperatures, waste composition and processing durations. Out of 120 odorous compounds, 52 were detected in seven categories under all tested conditions, with significant variations...

The aim of this case series was to describe the differences between maternal and fetal blood-gas results during anesthesia. Sixteen singleton adult merino ewes weighing 60.1 ± 5.1 kg at 125.7 d (124 to 126 d) gestation were anesthetized. Maternal (radial) and fetal (umbilical) arterial blood gas samples were collected 79 ± 6 min after the start of anesthesia if maternal mean arterial pressure (MAP) was stable and > 65 mmHg. Fetal pH, partial arterial pressure of oxygen (PaO2), glucose, arterial hemoglobin oxygen saturation (SaO2), sodium, and chloride were significantly lower and fetal partial arterial pressure of carbon dioxide (PaCO2), lactate, hematocrit, total hemoglobin, potassium, and calcium were significantly higher than maternal blood-gas values...

Mineral hydrocarbons consist of two fractions, mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOAH is a potential public health hazard because it may include carcinogenic polycyclic compounds. In the present study, 400 MHz nuclear magnetic resonance (NMR) spectroscopy was introduced, in the context of official controls, to measure MOSH and MOAH in raw materials or pure mineral hydrocarbon final products (cosmetics and medicinal products). Quantitative determination (qNMR) has been established using the ERETIC methodology (electronic reference to access in vivo concentrations) based on the PULCON principle (pulse length based concentration determination)...

BACKGROUND: Brain death (BD) is a donor-associated risk factor that negatively affects transplantation outcome. The inflammation associated with BD appears to have a negative effect on organ quality. Complement activation, apoptosis, and pro-inflammatory cytokine and chemokine expression are significantly increased after BD. To better understand this process, we investigated plasma chemokine and cytokine levels for 8h after BD in a rodent model. METHODS: Thirteen healthy adult male Sprague Dawley rats were intubated and mechanically ventilated...

Knowledge of intracellular metabolite levels is important for the understanding of metabolic flux distributions. Whole-cell biosensors of key metabolites are ideal for the monitoring of carbon flow in important metabolic pathways, thus guiding metabolic engineering for microbial improvement. However, lack of biosensors for metabolites of interests has limited their applications. In this study, a genetically encoded whole-cell biosensor specifically responding to shikimic acid has been developed by screening a site-saturation mutagenesis library of the binding pocket of a uric acid-responsive regulatory protein...

Diabetics may encounter different foot problems, which easily lead to infection, ulcers, and increased risk of amputation due to nerve or vascular injury. In order to reduce the risk of amputation, Buerger's exercise is one of the frequently used rehabilitation to improve the blood circulation in the lower limbs. However, it is difficult to evaluate the rehabilitation efficiency of Buerger's exercise objectively. In this study, a novel non-invasively optical system was developed to non-invasively monitor the change of the foot blood circulation before and after long-term Buerger's exercise...

Dichloroacetate (DCA) can reverse the glycolytic phenotype that is responsible of increased lactate production and extracellular pH acidification in cancer cells. Magnetic resonance imaging-chemical exchange saturation transfer (MRI-CEST) pH mapping is a novel non-invasive imaging approach that can measure in vivo extracellular tumour pH. We examined whether MRI-CEST pH mapping can monitor in vivo changes in tumour acidosis for assessing treatment response to DCA. Cell viability and extracellular pH were assessed in TS/A breast cancer cells treated with 1-10 mM DCA for 24 h in normoxia or hypoxia (1% O2) conditions...

Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insufflation (T2); surgery (T3); CO2PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO2, DP and SP were recorded compared with T0; a decrease in SatO2 was also observed at T5...

BACKGROUND: The therapeutic decision to close patent ductus arteriosus in preterm infants entails great uncertainty. Near-infrared spectroscopy is a noninvasive bedside technique used to monitor mixed regional oxygen saturation. We hypothesized that near-infrared spectroscopy could identify preterm infants at risk of mesenteric hypoperfusion associated with hemodynamically significant ductus arteriosus. METHODS: This is a prospective observational study including consecutively admitted preterm infants with a gestational age <32 weeks...

Chemical stabilization of tank residual waste is part of a Hanford Site tank closure strategy to reduce overall risk levels to human health and the environment. In this study, a set of column leaching experiments using tank C-104 residual waste were conducted to evaluate the leachability of uranium (U) and technetium (Tc) where grout and hydrated lime were applied as chemical stabilizing agents. The experiments were designed to simulate future scenarios where meteoric water infiltrates through the vadose zones into the interior of the tank filled with layers of grout or hydrated lime, and then contacts the residual waste...

Preterm infants often require mechanical ventilation due to lung immaturity including reduced or abnormal surfactant. Since cyclic stretch with cycle-by-cycle variability is known to augment surfactant release by epithelial cells, we hypothesized that such in vivo mechanotransduction improves surfactant maturation and hence lung physiology in preterm subjects. We thus tested whether breath-by-breath variability in tidal volume (VT) in variable ventilation (VV) can be tuned for optimal performance in a preterm lamb model...

INTRODUCTION: Rumination, cognitive control deficits, cognitive saturation, and loss of inhibition are the major hypotheses used to explain depressive disorders. A few studies have nevertheless looked at the form of thought. In this study, we will test a double measurement of the number of thoughts and a double measurement of the flow of thought together with their correlation with well-being, mental pain, and depression. MATERIAL AND METHODS: Between May and September 2015, 68 subjects, initially admitted as emergencies for acute anxiety depressive disorders and/or suicide attempts and subsequently monitored as post-emergency outpatients in medico-psychological consultations agreed to complete a set of Visual Analogue Scales measuring their well-being, their mental pain, their estimated number of thoughts and the how agitated these thoughts are estimated to be...

Oxygenation, measured by near-infrared spectroscopy (NIRS), in inactive muscles decreases during high-intensity exercise because of the decrease of oxygen supply. However, there have been few reports regarding recovery of inactive muscle oxygenation after exercise. This study was performed to examine reoxygenation in the biceps brachii muscle (BB) after supramaximal cycling exercise. Six active young male volunteers (age: 22  ±  3 years, peak oxygen uptake (VO2peak): 53.8  ±  5.4 mL/kg/min, mean  ±  S...

This study investigates the relationship between brain oxygenation, assessed by means of near infrared spectroscopy (NIRS), and brain function, assessed by means of electroencephalography (EEG). Using NIRS signals measuring the regional cerebral oxygen saturation (rScO2) and computing the fractional tissue oxygen extraction (FTOE), we compared how these variables relate to different features extracted from the EEG, such as the inter-burst interval (IBI) duration and amplitude, the amplitude of the EEG, and the amplitude of the burst...
