BACKGROUND: Asphyxia is the most common reason for newborns to fail to make a successful fetal to neonatal transition. There is currently a lack of data evaluating hemodynamic effects of epinephrine during neonatal cardiopulmonary resuscitation. METHODS: Twenty-four newborn piglets were exposed to asphyxia. Thereafter, positive pressure ventilation was commenced for 30 s, followed by chest compressions (CC). Piglets were randomized into three experimental groups: 3:1 compression:ventilation ratio; CC during sustained inflation (SI) at a rate of 90 CC per minute, or CC during SI at a rate of 120 CC per minute...

AIM: This work presents a label-free platform for dopamine (DA) monitoring based on the spectroscopic properties of laccase. RESULTS: Working in batch mode, DA ranging from 25 to 250 μM, can be determined without the interference of norepinephrine and epinephrine. Laccase immobilized in a polyacrylamide film is the basis of a platform for the label-free determination of DA. The linear range goes from 100 to 900 μM with an RSD of 5.3% and a film lifetime of more than 30 measurements...

Alcohol intake and sleep deprivation are conditions that cause changes in the physiological status. However, the relationship between biological markers and mood states is not entirely clear yet. The purpose of the study was to compare isolated and combined effects of alcohol intake and sleep deprivation on hormonal and inflammatory responses and in changes in the state of mood. Also, we intended to explain possible changes in mood states through biochemical variations using multiple stepwise regression analysis...

Anaphylaxis is defined as a severe life-threatening generalized or systemic hypersensitivity reaction characterized by rapidly developing airway and/or circulation problems. It presents with very different combinations of symptoms and apparently mild signs and can progress to fatal anaphylactic shock unpredictably. The difficulty in recognizing anaphylaxis is due, in part, to the variability of diagnostic criteria, which in turn leads to a delay in administration of appropriate treatment, thus increasing the risk of death...

Anaphylaxis is a severe, life-threatening generalized or systemic hypersensitivity reaction that requires rapid and adequate care. This study aimed to obtain an integrated view of the level of physicians' knowledge related with treatment of anaphylaxis in studies published within the last 5 years. Sixteen studies were found and four points were identified as of the great interest to the authors: (1) emergency pharmacological treatment, (2) epinephrine auto-injectors prescription, (3) knowledge of the main signs of anaphylaxis, and (4) admission of the patient to verify biphasic reactions...

Transitioning of rhinologic procedures from the operating room to the office setting in selected patients is a rising trend. An effective pain-control, patient-preparation protocol is essential, especially with advanced in-office rhinologic procedures such as hybrid balloon sinus dilation (BSD), in which other procedures such as ethmoidectomy, turbinate reduction, and other procedures are concomitantly performed. A regimen using oral sedation, topical tetracaine gel, topical tetracaine/epinephrine-soaked cottonoid packs, and intranasal local infiltrative anesthesia can vary significantly in effectiveness and be suboptimal at times (as determined by using treated patients as historical controls)...

OBJECTIVE: The time taken to reach maximal haemostatic effect following local anaesthesia with epinephrine is generally believed to be <10 min. This is based on clinical experience and indirect measurements of perfusion using methods such as laser Doppler flowmetry and oxygen spectroscopy. However, the only study in which bleeding has been measured quantitatively in an intra-operative setting in humans showed that the full haemostatic effect was not achieved until 30 min after anaesthesia...

Cardiac arrhythmia is a common cause of mortality, and its progression may be due to abnormal sympathetic nerve activity and catecholamine release. Besides, lactate dehydrogenase (LDH) and creatine kinase (CK) downregulation and adiponectin expression play important roles in promoting coronary artery disease. The study aimed to examine the possible cardioprotective effect of members of phosphodiesterase type 5 (PDE-5) inhibitors in epinephrine-induced arrhythmia in rats. Arrhythmia was induced by cumulative boluses of epinephrine (4, 8, 16, 32, 64, and 128 mg/kg) given at 10-min intervals...

We evaluated the feasibility, tolerability, and efficacy of a strategy for transaxillary artery intra-aortic balloon pump placement for extended mechanical circulatory support of patients with postcardiotomy shock as a bridge to recovery. Patients requiring prolonged intra-aortic balloon pump support for postcardiotomy heart failure were identified. Intra-aortic balloon pump was tunneled through a 6-mm Dacron graft anastomosed to the right axillary artery. The intra-aortic balloon pump catheter is advanced under fluoroscopic guidance into the descending thoracic aorta...

Monoamine neurotransmission is key to neuromodulation, but imaging monoamines in live neurons has remained a challenge. Here we show that externally added ortho-phthalaldehyde (OPA) can permeate live cells and form bright fluorogenic adducts with intracellular monoamines (e.g. setrotonin, dopamine and nor-epinephrine) and with L-DOPA, which can be imaged sensitively using conventional single-photon excitation in a fluorescence microscope. The peak excitation and emission wavelengths (λex = 401 nm and λem = 490 nm for serotonin; λex = 446 nm and λem = 557 nm for dopamine; and λex = 446 nm and λem = 544 nm for nor-epinephrine) are accessible to most modern confocal imaging instruments...

Neurotransmitters are important biochemical molecules that control behavioral and physiological functions in central and peripheral nervous system. Therefore, the analysis of neurotransmitters in biological samples has a great clinical and pharmaceutical importance. To date, various methods have been developed for their assay. Of the various methods, the electrochemical sensors demonstrated the potential of being robust, selective, sensitive, and real time measurements. Recently, conducting polymers (CPs) and their composites have been widely employed in the fabrication of various electrochemical sensors for the determination of neurotransmitters...

The purpose is devoted to test of hypothesis that patients with chronic cerebral ischemia (CCI) have decreased secretion of platelet ADP as the reason of platelet aggregation restriction in response to stimulation of adrenaline. Methods. We used platelet-rich plasma which was separated by centrifugation from peripheral blood of 55 patients with a diagnosis of CCI of stage 1-2. Platelets aggregation was studied on aggregometer Chrono - Log (USA). ADP and Epinephrine were used for platelet stimulation at effective concentration (EC50)...

In this case report we describe a 62-year-old man, intoxicated with losartan, an angiotensin-II receptor antagonist. The patient presented with a systolic blood pressure of 60 mmHg, metabolic acidosis, and hyperglycaemia. His condition worsened within the first hour of arrival despite infusion of four litres of saline, epinephrine, norepinephrine, and vasopressin as well as insulin and antibiotics. Intravenous methylene blue 75 mg was infused over five minutes. Within 30 minutes his systolic pressure increased to 100 mmHg, and the infusion of epinephrine could be reduced four hours later...

Exposure of chicks to a high ambient temperature (HT) has previously been shown to increase neuropeptide Y (NPY) mRNA expression in the brain. Furthermore, it was found that NPY has anti-stress functions in heat-exposed fasted chicks. The aim of the study was to reveal the role of central administration of NPY on thermotolerance ability and the induction of heat-shock protein (HSP) and NPY sub-receptors (NPYSRs) in fasted chicks with the contribution of plasma metabolite changes. Six- or seven-day-old chicks were centrally injected with 0 or 375 pmol of NPY and exposed to either HT (35 ± 1°C) or control thermoneutral temperature (CT: 30 ± 1°C) for 60 min while fasted...

Non-muscle myosin II has been implicated in regulation of von Willebrand factor (VWF) release from endothelial Weibel-Palade bodies (WPBs), but the specific role of myosin IIa isoform is poorly defined. Here, we report that myosin IIa is expressed both in primary human endothelial cells and intact mouse vessels, essential for cAMP-mediated endothelial VWF secretion. Down-regulation of myosin IIa by shRNAs significantly suppressed both forskolin- and epinephrine-induced VWF secretion. Endothelium-specific myosin IIa knockout mice exhibited impaired epinephrine-stimulated VWF release, prolonged bleeding time and thrombosis...

INTRODUCTION: It has been recommended to place patients in an upright position after administration of an inferior alveolar nerve block (IANB), theoretically allowing the anesthetic to diffuse in an inferior direction and resulting in better pulpal anesthesia. The purpose of this study was to compare an upright versus a supine position on the success of pulpal anesthesia when an IANB was administered in asymptomatic teeth. METHODS: One hundred ten asymptomatic subjects were randomly given IANBs by using 2% lidocaine with 1:100,000 epinephrine while they were in an upright position and supine position at 2 different appointments spaced at least 2 weeks apart...
