The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).

The cells found in the body fluid circulating throughout the CARDIOVASCULAR SYSTEM.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

One important index to assess left ventricular diastolic function is the quantitative measurement of atrioventricular junction (AVJ) motion in one cardiac cycle including systole and diastole. The best way to perform the measurement is to use a software tool that can conduct AVJ motion tracking from cine cardiovascular magnetic resonance (CMR) images. In this paper, a software tool for this purpose is presented by using the insight segmentation and registration toolkit (ITK), the visualization toolkit (VTK), and Qt. We propose a surface area-based tracking approach in the software tool. In the tracking approach to obtain the surface area swept by six points being tracked, we manually select six points from four-, three- and two-chamber views of CMR images. After that, we reconstruct the 3-D coordinates of the six points from image acquisition parameters extracted from DICOM files. We perform interpolation by using parametric cubic curve fitting techniques. From the curve fitting results, we ...
Injury to vital structures posterior to the sternum is a complication associated with redo sternotomy in congenital cardiac surgery. The goal of our study was a novel evaluation of real-time cine cardiovascular magnetic resonance (CMR) to predict the presence of significant retrosternal adhesions of cardiac and vascular structures prior to redo sternotomy in patients with congenital heart disease. Twenty-three patients who had prior congenital heart surgery via median sternotomy had comprehensive CMR studies prior to redo sternotomy. The real time cine (RTC) sequence that was used is an ungated balanced steady-state free precession (bSSFP) sequence using SENSitivity Encoding for acceleration with real-time reconstruction. Spontaneously breathing patients were instructed to take deep breaths during the acquisition whilst increased tidal volumes were delivered to mechanically ventilated patients. All patients underwent redo cardiac surgery subsequently and the presence and severity of retrosternal

Purpose: Patients undergoing radiotherapy (RT) for left-sided breast cancer have increased risk of coronary artery disease. Deep Inhalation Breath Hold assisted RT (DIBH-RT) is shown to increase the geometric separation of the target area and heart, reducing cardiac radiation dose. The purposes of this study are to use Cine MV portal images to determine the stability of spirometer-guided DIBH-RT and examine the dosimetric cardiopulmonary impact of this technique. Methods: Twenty consecutive patients with left-sided breast cancer were recruited to the IRB-approved study. Free-breathing (FB) and DIBH-CTs were acquired at simulation. Rigid registration of the FB-CT and DIBH-CT was performed using primarily breast tissue. Treatment plans were created for each FB-CT and DIBH-CT using identical paired tangent fields with field-in-field or electronic compensation techniques. Dosimetric evaluation included mean and maximum (Dmax) doses for the left anterior descending artery (LAD), mean heart dose, and ...
BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is guided bronchoscopy to pulmonary nodules (PN) that relies on a preprocedural chest CT to create a three-dimensional (3D) virtual airway map. The CT is traditionally done at a full inspiratory breath hold (INSP), but the procedure is performed while the patient tidal breaths, when lung volumes are closer to functional residual capacity. Movement of a PN from INSP to expiration (EXP) has been shown to average 17.6 mm. Therefore, the hypothesis of this study is that preprocedural virtual maps built off a CT closer to physiological lung volumes during bronchoscopy may better represent the actual 3D location of a PN ...
Cardiac magnetic resonance (CMR) is superior to other imaging modalities for determining infarct size (IS) (1) and late gadolinium enhancement (LGE) CMR is considered the gold standard for quantifying acute and chronic myocardial infarction (MI) (2,3). The pathophysiological foundation for hyperenhancement on LGE-CMR is based on an increased distribution volume of an extracellular contrast agent within scarred tissue in chronic MI and in cells that have lost their cellular integrity due to necrosis in acute myocardial infarction (AMI) (4,5). Reimer and Jennings (6) described an ischemic zone histopathologically in AMI containing viable myocytes adjacent to the infarction as the border zone, i.e., salvaged myocardium. Arheden et al. (4,5) showed that salvaged myocardium (myocardium at risk [MaR] − infarction) had an increased extracellular volume (ECV) compared with normal myocardium measured by CMR and validated this by radioisotopes in rats subjected to ischemia. Experimental studies with ...

Multislice CT scanners are the newest class of CT scanners and they have not one but many detectors. These scanners can acquire up to 4 slices of data from the body in the same time it takes a single-slice CT scanner to acquire one. Multislice CT allows for rapid cardiac imaging during a single breath-hold. A multislice scanner operated in helical mode provides information that can be used to reconstruct 3D cardiac images in arbitrary phases of the cardiac cycle.. A 71-year-old man with hypertension, hypercholesterolemia, and known aortic and peripheral vascular disease was imaged with a LightSpeed 4-slice, multislice CT scanner (GE Medical Systems). Ten minutes before the cardiac scan, the patient received intravenous contrast material (150 mL of 300 mgI/mL) for a CT study of his abdomen. The cardiac scan was acquired during a 35-s breath-hold, and simultaneous acquisition of the ECG enabled reconstruction using retrospective gating (Figure 1⇓). The helical pitch was 0.85 (relative to the ...

AU - Rosenzweig, K.. AU - Mageras, G.. PY - 2006/9. Y1 - 2006/9. N2 - Respiration-gated radiotherapy offers a significant potential for improvement in the irradiation of tumour sites affected by respiratory motion such as lung, breast and liver tumours. An increased conformality of irradiation fields leading to decreased complications rates of organs at risk (lung, heart) is expected. Four main strategies are used to reduce respiratory motion effects: integration of respiratory movements into treatment planning, breath-hold techniques, respiratory gating techniques, and tracking techniques. Measurements of respiratory movements can be performed either in a representative sample of the general population, or directly on the patient before irradiation. The measured amplitude could be applied to a ...
In this study, we did not observe any significant difference in the improvement in PEF after inhalation of salbutamol using a pMDI and VHC by either single maximal inhalation with a breath-hold technique or 5 tidal breaths technique.. It has been observed that many children who suffer from asthma use their inhaler devices incorrectly, even after instruction for correct use.8,9 The most difficult skill for children using a metered-dose inhaler was progressive inhalation of the medicine slowly and deeply through the mouth and the need to hold their breath for a count of 10.10-12. A simple and efficient method to deliver drug through a pMDI in children must be identified to improve compliance and symptom control, and to minimize side effects. Patients can take a slow single breath to retrieve the medication or take tidal breaths from the chamber as per the Global Initiative on Asthma. There are very few studies done in this area in children to compare effectiveness of either method. The usual ...

The main finding of this study is that MI can be accurately detected (91% accuracy) with the use of an ultrafast DE-CMR technique that can acquire snapshot images during free breathing. Importantly, the technique was robust and provided full coverage of the heart in ,30 seconds, and specificity was excellent at 96%. However, there were some limitations compared with the standard approach. Sensitivity was 11% lower (87% versus 98%), and there was a tendency to underestimate both global infarct size and the transmural extent of infarction.. Despite these limitations, the development of subsecond imaging has important clinical implications. For instance, although CMR is a highly attractive modality for the assessment of MI and viability,22 some practical drawbacks potentially limit the impact of this technology for general clinical practice. In comparison to other imaging modalities, standard CMR is more complex: Patient and protocol setup times are longer, and multiple breath-holds and longer ...
After your usual exhale, pinch your nose and count your BHT (breath holding time) in seconds. Keep nose pinched until you experience the first desire to breathe. Practice shows that this first desire appears together with an involuntary push of the diaphragm or swallowing movement in the throat. (Your body warns you, Enough!) If you release the nose and start breathing at this time, you can resume your usual breathing pattern (in the same way as you were breathing prior to the test). Do not extend breath holding too long. This is the most common mistake. You should not gasp for air or open your mouth when you release your nose. The test should be easy and not cause you any stress.

The most dangerous part of any dive is of course when the partial pressure of oxygen in the brain gets to a point where it can no longer sustain consciousnesses. As we progress with our training we slowly push of c02 threshold back (we also push our 02 threshold back, but often slower as it is more closely connected to fitness and condition), learning to deal with the 2nd and final third and moving us closer to the Danger zone. This may take months or years to achieve.. In-fact, new freedivers (as long as they follow training guidelines and have formal training) are often less likely to blackout/loose motor control than some more advanced divers, simply as they as new divers have a lower tolerance to c02 so will come up sooner, far away from the danger zone.

Roberto M. Lang, MD Victor Mor-Avi, PhD. OVER THE LAST 3 DECADES, 3D ECHOCARDIOGRAPHIC IMAGING HAS BEEN DEVELOPED with the aim of providing additional anatomic detail and improved spatial relationships that were not available from 2D images. To achieve this goal, the most significant advance during the last decade was the introduction of matrix-array transducers, which have enabled the transition from slow and labor-intense off-line reconstruction of 3D datasets to real-time volumetric imaging. These transducers, which contain arrays of piezoelectric elements capable of scanning pyramidal volumes rather than thin slices, allow fast acquisition of RT-3DE datasets during a single breath-hold, without the need for off-line reconstruction. This, to a large extent, has eliminated motion artifacts known to have adversely affected the now-outdated multiplane acquisition and reconstruction. The use of parallel processing met the need for increased computational power, which was necessary to process the ...

The smart e-bike monitoring system (SEMS) is a platform for the real-time acquisition of usage data from electrically-assisted bikes (also called pedelecs or e-bikes). It is autonomous (runs off the bike battery), replicable (open source and open hardware), scalable (different fleet sizes) and modular (sensors can be added), so it can be used for further research and development. The system monitors location (global positioning system), rider control data (level of assistance) and other custom sensor input in real time. The SEMS data feeds an online interface for data analysis, for riders to view their own data and for sharing on social media. The basic system can be replicated by other researchers and can be extended with modules to explore various issues in e-bike research. The source code and hardware design are publicly available, under the General Public License, for non-commercial use. SEMS was implemented on 30 bikes and collected data during 10 months of real-word trials in the UK. This study

PURPOSE: To combine global cardiac function imaging with compressed sensing (CS) in order to reduce scan time and to validate this technique in normal mouse hearts and in a murine model of chronic myocardial infarction. MATERIALS AND METHODS: To determine the maximally achievable acceleration factor, fully acquired cine data, obtained in sham and chronically infarcted (MI) mouse hearts were 2-4-fold undersampled retrospectively, followed by CS reconstruction and blinded image segmentation. Subsequently, dedicated CS sampling schemes were implemented at a preclinical 9.4 T magnetic resonance imaging (MRI) system, and 2- and 3-fold undersampled cine data were acquired in normal mouse hearts with high temporal and spatial resolution. RESULTS: The retrospective analysis demonstrated that an undersampling factor of three is feasible without impairing accuracy of cardiac functional parameters. Dedicated CS sampling schemes applied prospectively to normal mouse hearts yielded comparable left-ventricular

AU - Sinha, Debasish. AU - Lutty, Gerard Anthony. PY - 2012/3. Y1 - 2012/3. N2 - VEGF 165b is an anti-angiogenic form of VEGF 165 produced by alternative splicing. The localization of pro-angiogenic VEGF 165 and anti-angiogenic VEGF 165b was investigated during development of the vasculatures in fetal human eyes from 7 to 21 weeks gestation (WG). The fetal vasculature of vitreous, which includes tunica vasculosa lentis (TVL), had moderate VEGF 165 immunoreactivity at 7WG and very little VEGF 165b. Both forms were elevated at 12WG. VEGF 165 then decreased around 17WG when the TVL regresses but VEGF 165b remained elevated. In choroid, VEGF 165 was present in forming choriocapillaris (CC) and retinal pigment epithelium (RPE) at 7WG while VEGF165b was present in CC and mesenchymal precursors within the choroidal ...

Chronic breath holding can harm your health, lead to exhaustion and compromise your work performance. Prolonged sitting in front of your screen has been described as the new smoking. Research also has shown that chronic sitting in the same position can create other problems such as back and neck pain. Withhold breath throws the nervous system into flight-or-flight mode, contributing to stress-related illnesses like heart disease, type 2 diabetes and cancer. Some studies have found that it is equal or worse than smoking cigarettes. Screen apnea also could explain a related phenomenon known as Zoom fatigue for the legions of people spending hours on end remote working, practicing telemedicine or taking online classes. And with the worsening of the pandemic, more people are forced to resort to funerals, hospital room visits and holiday celebrations-all virtually. There are a number of actions you can take to prevent screen apnea, keep your natural breathing cycle and maintain your energy and job ...
Atherosclerotic cardiovascular disease is the leading cause of death worldwide. To decrease mortality and morbidity in cardiovascular disease, the development of accurate, non-invasive methods for early diagnosis of atherosclerotic cardiac and vascular engagement is of considerable clinical interest. Cardiovascular ultrasound imaging is today the cornerstone in the routine evaluation of cardiovascular function and recent development has resulted in two new techniques, tissue velocity imaging (TVI) and speckle tracking, which allow objective quantification of cardiovascular function. TVI and speckle tracking are the basis for three new approaches to cardiac and vascular monitoring presented in this thesis: wave intensity wall analysis (WIWA), two-dimensional strain imaging in the common carotid artery, and the state diagram of the heart.. WIWA uses longitudinal and radial strain rate as input for calculations of wave intensity in the arterial wall. In this thesis, WIWA was validated against a ...

Aging is a complex process. Progressive molecular changes lead to a decline in the ability of living beings to maintain homeostasis and overcome cellular stress, protein damage, and disease (1). At the organismal level, stem cells play a fundamental role in maintaining tissue integrity, and their functional and proliferative exhaustion is a major cause of aging (2). Hematopoietic stem cells, which reside in the bone marrow and give rise to all blood cell types, are a favored model for studying stem cell aging. However, the exact molecular mechanisms underlying their aging remain unknown. Sirtuins, a family of nutrient-sensing proteins (SIRT1 to SIRT7) that regulate gene expression and protein function in mammalian cells, orchestrate multiple pathways that are associated with age-related processes and longevity. On page 1374 of this issue, Mohrin et al. (3) connect SIRT7 to a metabolic checkpoint that controls aging in hematopoietic stem cells.. ...
