If they can be established as a TUMOR CELL LINE, they can be propagated in cell culture indefinitely.Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Skin Neoplasms: Tumors or cancer of the SKIN.Neoplasms, Second Primary: Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.Iridium Radioisotopes: Unstable isotopes of iridium that decay or disintegrate emitting radiation. Ir atoms with atomic weights 182-190, 192, and 194-198 are radioactive iridium isotopes.Microwaves: That portion of the electromagnetic spectrum from the UHF (ultrahigh frequency) radio waves and extending into the INFRARED RAYS frequencies.Models, Biological: Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.Cell Line: Established cell cultures that have the potential to propagate indefinitely.Analysis of Variance: A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.Cisplatin: An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.Brain Diseases: Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.Signal Transduction: 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.Cytogenetics: A subdiscipline of genetics which deals with the cytological and molecular analysis of the CHROMOSOMES, and location of the GENES on chromosomes, and the movements of chromosomes during the CELL CYCLE.Genetic Speciation: The splitting of an ancestral species into daughter species that coexist in time (King, Dictionary of Genetics, 6th ed). Causal factors may include geographic isolation, HABITAT geometry, migration, REPRODUCTIVE ISOLATION, random GENETIC DRIFT and MUTATION.Pedigree: The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.Space Flight: Travel beyond the earth's atmosphere.Mice, Nude: Mutant mice homozygous for the recessive gene "nude" which fail to develop a thymus.

Evaluation of the impact of Chernobyl on the prevalence of congenital anomalies in 16 regions of Europe. EUROCAT Working Group. (1/64)BACKGROUND: Surveillance data from population-based congenital anomaly registers in 16 regions of Europe (mainly Western Europe) were analysed to assess the impact of the Chernobyl accident on the prevalence of selected congenital anomalies. METHODS: Three cohorts of pregnancies were defined: those exposed during the first month following Chernobyl (External Exposure Cohort), the first year (Total Exposure Cohort) and the two subsequent years (Control Cohort). Expected numbers of congenital anomalies in these cohorts were calculated from 1980-1985 baseline rates. Registries were grouped into three exposure categories according to first-year exposure estimates. RESULTS: There was no overall or dose-related increase in prevalence in the two exposed cohorts for Down's Syndrome, neural tube defects, other central nervous system defects or eye defects. There was a statistically significant overall 22% (95% CI: 13-31%) excess of Down's Syndrome in the Control Cohort, with no dose-response relationship. CONCLUSIONS: Chernobyl had no detectable impact on the prevalence of congenital anomalies in Western Europe, suggesting that in retrospect the widespread fear in the population about the possible effects of exposure on the unborn fetus was not justified. An increasing prevalence of Down's Syndrome in the 1980s, probably unrelated to Chernobyl, merits further investigation. (+info)
Reduced inhibition in an animal model of cortical dysplasia. (2/64)Cortical dysplasia has a strong association with epilepsy in humans, but the underlying mechanisms for this are poorly understood. In utero irradiation of rats produces diffuse cortical dysplasia and neuronal heterotopia in the neocortex and hippocampus. Using in vitro neocortical slices, whole-cell patch-clamp recordings were obtained from pyramidal neurons in dysplastic cortex and control neocortex. Spontaneous IPSCs were reduced in amplitude (35%) and frequency (70%) in pyramidal cells from dysplastic cortex. Miniature IPSCs were reduced in frequency (66%) in dysplastic cortex. Two additional measures of cortical inhibition, monosynaptic evoked IPSCs and paired pulse depression of evoked EPSCs, were also impaired in dysplastic cortex. Spontaneous EPSCs were increased in amplitude (42%) and frequency (77%) in dysplastic cortex, but miniature EPSCs were not different between the two groups. These data demonstrate significant physiological impairment in inhibitory synaptic transmission in experimental cortical dysplasia. This supports previous immunohistochemical findings in this model and observations in humans of a reduction in the density of inhibitory interneurons in dysplastic cortex. (+info)
Maintaining a proper perspective of risk associated with radiation exposure. (3/64)OBJECTIVES: The objectives of this article are to provide the reader with (a) a brief discussion of actual, perceived, and acceptable risks associated with radiation exposure; (b) a basic review of radiation protection units and a discussion as to how these units are used to estimate risk associated with occupational radiation exposure; (c) a summary of radiation doses required for specific human biologic responses and a comparison of relative doses encountered in a variety of clinical situations; and (d) a practical approach to discussing relative risks associated with medical radiation exposures when patients inquire.

Dependence of malformation upon gestational age and exposed dose of gamma radiation. (4/64)In order to evaluate the importance of gestational age and the dose-incidence relationship by gamma radiation, pregnant ICR mice at gestational days from 2.5 to 15.5 days post-coitus (p.c.) were exposed to a single dose of 2.0 Gy and also at day 11.5 after conception, which was the most sensitive stage for the induction of major congenital malformations. The animals were sacrificed on day 18 of gestation and the fetuses were examined for mortality, growth retardation, changes in head size and other morphological abnormalities. The only demonstrable effect of irradiation during the pre-implantation period was an increase in prenatal mortality. Resorptions were maximal on exposure at day 2.5 after conception. The pre-implantation irradiated embryos which survived did not show any major fetal abnormalities. A small head, growth retardation, a cleft palate, dilatation of the cerebral ventricle, a renal pelvis, and abnormalities of the extremities and tail after exposure were prominent during the organogenesis period, especially on day 11.5 of gestation. As for the dose-incidence relationship, the incidence of a small head, growth-retarded fetuses, a cleft palate, dilatation of cerebral ventricle and abnormalities of the extremities in live fetuses rose as the radiation dose increased. The result indicated that the late period of organogenesis in the development of the brain, skull and extremities of a mouse was a particularly sensitive phase. The threshold doses of radiation that induced a cleft palate and dilatation of the cerebral ventricle, and abnormal extremities were between 1.0 and 2.0 Gy, and between 0.5 and 1.0 Gy, respectively.

The combined effects of MRI and X-rays on ICR mouse embryos during organogenesis. (5/64)The combined effects of X-rays and magnetic resonance imaging (MRI) on mouse embryos at an early stage of organogenesis were investigated. Pregnant ICR mice were irradiated on day 8 of gestation with X-rays at a dose of 1 Gy and/or MRI at 0.5 T for 1 hour. The mortality rates of the embryos or fetuses, the incidence of external malformations, the fetal body weight and the sex ratio were observed at day 18 of gestation. A significant increase in embryonic mortality was observed after exposure to either 1 Gy of X-radiation or 0.5 T MRI. However, the combined X-rays and MRI did not show a statistically significant increase in embryonic mortality compared with the control. External malformations, such as exencephaly, a cleft palate and anophthalmia, were observed in mice irradiated with X-rays and/or MRI. The incidence of each malformation in all treated groups increased with statistical significance compared with the control mice. The incidence in mice irradiated with both X-rays and MRI was lower than in mice irradiated with only X-rays. The combined effects of the combination of radiation and MRI on the external malformations might be antagonistic. There were no statistically significant differences in fetal death, fetal body weight and sex ratio among all experimental groups. (+info)
Effects of a 4.7 T static magnetic field on fetal development in ICR mice. (6/64)In order to determine the effects of a 4.7 T static magnetic field (SMF) on fetal development in mice, we evaluated fetal teratogenesis and endochondral ossification following exposure in utero. Pregnant ICR mice were exposed to a 4.7 T SMF from day 7.5 to 9.5 of gestation in a whole-body dose, and sacrificed on day 18.5 of gestation. We examined the incidence of prenatal death, external malformations and fetal skeletal malformations. There were no significant differences observed in the incidence of prenatal death and/or malformations between SMF-exposed mice and control mice. Further, we evaluated the immunoreactivity for the vascular endothelial growth factor (VEGF), which is implicated in angiogenesis and osteogenesis, in the sternum of fetal mice following magnetic exposure. Our studies also indicated that on day 16.5 of gestation following SMF exposure, the immunoreactivity for VEGF was increased compared to unexposed controls. However, it was decreased in the exposed group compared to the control group on day 18.5 of gestation. DNA and proteoglycan (PG) synthesis were also measured in rabbit costal growth plate chondrocytes in vitro. No significant differences were observed in DNA synthesis between the SMF exposed chondrocytes and the control chondrocytes; however, PG synthesis in SMF exposed chondrocytes increased compared to the controls. Based on these results, we suggest that while SMF exposure promoted the endochondral ossification of chondrocytes, it did not induce any harmful effects on fetal development in ICR mice. (+info)
Model prediction of treatment planning for dose-fractionated radioimmunotherapy. (7/64)BACKGROUND: Clinical trials of radioimmunotherapy (RIT) often use dose fractionation to reduce marrow toxicity. The dosing scheme can be optimized if marrow and tumor cell kinetics following radiation exposure are known. METHODS: A mathematic model of tumor clonogenic cell kinetics was combined with a previously reported marrow cell kinetics model that included marrow stromal cells, progenitor cells, megakaryocytes, and platelets. Reported values for murine tumor and marrow cellular turnover rates and radiosensitivity were used in the model calculation. RESULTS: Given a tolerated level of thrombocytopenia, there is a fractionation scheme in which total radioactive dose administration can be maximized. Isoeffect doses that had different numbers of fractions and total radioactivity, but induced identical platelet nadirs of 20%, were determined. Assuming identical tumor uptake for all dose fractions, six tumor types were examined: early-responding tumors, late-responding tumors, and tumors that lacked a late-responding effect, with either constant or accelerated doubling time. For most tumor types, better tumor control (tumor growth delay and nadir of survival fraction) was predicted for a dosing scheme in which total radioactive dose was maximized. For late-responding tumors with accelerated doubling time, tumor growth delay increased, but the nadir of survival fraction became shallower as the number of fractions increased. CONCLUSIONS: A mathematic model has been developed that allows prediction of the nadir and duration of thrombocytopenia as well as tumor clonogenic cell response to various RIT doses and fractionation schemes. Given a maximum tolerated level of thrombocytopenia, the model can be used to determine a dosing scheme for optimal tumor response. (+info)
Elevated minisatellite mutation rate in the post-chernobyl families from ukraine. (8/64)Germline mutation at eight human minisatellite loci has been studied among families from rural areas of the Kiev and Zhitomir regions of Ukraine, which were heavily contaminated by radionuclides after the Chernobyl accident. The control and exposed groups were composed of families containing children conceived before and after the Chernobyl accident, respectively. The groups were matched by ethnicity, maternal age, parental occupation, and smoking habits, and they differed only slightly by paternal age. A statistically significant 1.6-fold increase in mutation rate was found in the germline of exposed fathers, whereas the maternal germline mutation rate in the exposed families was not elevated. These data, together with the results of our previous analysis of the exposed families from Belarus, suggest that the elevated minisatellite mutation rate can be attributed to post-Chernobyl radioactive exposure. The mechanisms of mutation induction at human minisatellite loci are discussed. (+info)

Pregnant ICR mice (Nihon-SLC) were used for in utero electroporation. Noon of the day at which the vaginal plug was detected was designated as embryonic day 0.5 (E0.5) and E19.5 was defined as P0.5. In utero electroporation was conducted on E13.5-13.75 embryos as described previously (Hatanaka et al., 2004) with minor modifications. Briefly, a 1-1.5 μl plasmid solution was injected into the lateral ventricle and 30 V or 40 V electric pulses of 50 ms duration were delivered at 200 ms intervals. Plasmids were prepared with the NucleoBond Midi Kit (Macherey-Nagel), suspended in PBS (0.1 m, pH 7.4) and electroporated at the following final concentrations: 1.0 μg/μl pCAG-EGFP-IRES-mito-mCherry for analysis of the mitochondrial distribution during the development of dendritic arbors; 3.0 μg/μl pCAG-Mfn1 and 1.0 μg/μl pCAG-EGFP-IRES-mito-mCherry for analysis of the mitochondrial distribution and dendritic morphology in Mfn1-overexpressing neurons; 3.0 μg/μl pCAG-Mfn1 and 1.0 μg/μl ...

This study aimed to evaluate the accuracy of radiographers screen-reading mammograms. Currently, radiologist workforce shortages may be compromising the BreastScreen Australia screening program goal to detect early breast cancer. The solution to a similar problem in the United Kingdom has successfully encouraged radiographers to take on the role as one of two screen-readers. Prior to consideration of this strategy in Australia, educational and experiential differences between radiographers in the United Kingdom and Australia emphasise the need for an investigation of Australian radiographers screen-reading accuracy. Ten radiographers employed by the Westmead Breast Cancer Institute with a range of radiographic (median = 28 years), mammographic (median = 13 years) and BreastScreen (median = 8 years) experience were recruited to blindly and independently screen-read an image test set of 500 mammograms, without formal training.

Until about a decade ago, the substructures seen in the Balmer-line profiles of active stars were generally regarded as too complex for quantitative study. Since then, however, detector technology has improved to the point where we can monitor the evolution of these structures with temporal sampling rates high enough to allow us to see coherent patterns in the data. Although some of the patterns that have emerged from such studies are consistent with stochastic flare activity, a large part of the complex substructure seen in the Balmer lines appears to be caused by mass motions of clumps of Balmer emitting and absorbing material. As these clumps are embedded in the much hotter ambient medium of the stellar corona, they are usually dubbed ``prominences" by analogy to solar prominences. Some of the mass motions seen in association with stellar flares are transient, and appear to resemble the prominence eruptions seen on the Sun in connection with coronal mass ejections and two-ribbon flares. ...
When compared to other common cancers, lung cancer patients are less likely to survive their cancer. This is often due to a delay in the recognition of the condition and performance of the chest X-ray (CXR). Delayed diagnosis reduces treatment choices because the cancer may have spread further and the person may have become too ill for treatment to be given safely. It is hoped that by diagnosing lung cancer sooner this will help improve survival, help with patient satisfaction and potentially extend the range of treatment options, which are more limited in delayed diagnosis. CXRs are often used when lung cancer is suspected, but there can be long delays for the results to be available to the patient and the GP. Radiographers traditionally take the X-ray, but they are reported by a radiologist, a medical specialist. Recent studies show that radiographers who have completed further training can report CXRs with similar accuracy to radiologists. This project will help to reduce delays in diagnosis ...

Both Becketts and Enos plays are filled with a wicked sense of humor.What separates both authors from their contemporaries, however, is their profound depth. Their work burrows down into the most intimate vulnerabilities of the human soul. With both writers, at one moment I am laughing myself to the floor and the next I feel as though I am having an epiphany. What makes Eno a Samuel Beckett for the Jon Stewart generation is that he is so much of our time. Just as Beckett exploited the forms of slapstick comedy, vaudeville, and silent movies, Eno puts his profound ideas in the forms of stand-up comedy and the 24-hour news cycle. The fact that he is able to tackle such weighty themes in these forms is exactly what makes his work so surprising and catches us off guard. He is one of the most exciting playwrights alive today and having him in residence at Cutting Ball this March is an extraordinary treat ...
Using a custom build spectrophotometer equipped with Helmholtz coils and designed to study the effects of magnetic fields on enzyme reactions in real-time we have investigated the influence of fields, from 100 ?T to 10 mT and at a variety of field frequencies, on the membrane bound enzymes alkaline phosphatase and acetylcholinesterase. We have also employed other methods to apply a magnetic field, e.g. Biostim. In contrast to earlier reports we have been unable to detect any field effects on these enzymes under any field/frequency regime. We discuss possible reasons for the discrepancy between this and earlier work and note the particularly complex influence of small temperature changes that may confound analysis.. ...

We all stood in perplexed silence for a moment. I looked at the chest X-ray on the box in front of me and systematically began to analyze it. Based on the size of the chest it looked like an adult, probably male since no breast shadows were evident. Good quality film, no rotation. Heart normal size. Lungs… Something about the lungs. They were clear for the most part: Black fields indicating that the X-rays were going clear through the mostly-air of the lungs to expose the film behind, blocked at regular intervals by the gentle white arcs of ribs bordering and encircling the chest. But in the blackness where there should be nothing - more white, something, some things, in the lungs blocking the X-rays, things that looked like huge cotton balls. "Fluffy infiltrates" is the term radiologists use for lesions such as these. I thought I could rattle off a few things that did this, but it would help to know more about this patient.

An MRI scanner is a short tunnel which is open at both ends. During the procedure, you lie on a motorised bed, which is moved inside the scanner.. A small receiving device is placed behind or around the part of your body being scanned. You are moved into the scanning tube, either head- or feet-first, depending on which part of your body is being scanned.. A computer is used to operate the MRI scanner. The computer is located in a different room to the scanner to keep it away from the magnetic field generated by the scanner.. As the radiographer operates the computer, they will also be in a separate room to you. You will hold a bell in your hand during the scan and if you need to talk to the radiographer you can ring the bell and talk to them via the intercom. The radiographer will be able to see you at all times on a television monitor.. During your scan, a friend or family member may be allowed to stay in the room with you. Children can usually have a parent with them. Anyone who stays in the ...

The CT scanner is a large ring-shaped machine. You will be asked to lie on a motorised bed that moves in and out of the hole. Only the part of your body that is inside the ring can be scanned.. Your radiographer will position the bed so that the correct part of your body is in the scanner. They will then leave the room and operate the scanner from a control room behind a window. This is because it is dangerous for staff to be exposed to X-rays every day. You will still be able to hear and speak to the radiographer during the procedure through an intercom.. You will be asked to lie very still and breathe normally while each scan is taken, to avoid blurring the images. You may be asked to inhale, exhale or hold your breath at certain points.. The X-ray unit inside the ring will rotate around you. Each time it goes round it creates a new X-ray scan. After each X-ray is completed, the bed on which you are lying is moved forward a small amount.. Several scans will be carried out and the whole ...

We have theoretically studied the combination effects of the electric and magnetic fields on the binding energy of an on-center donor impurity in disc-shaped GaAs/Al0.3Ga0.7As quantum dots (QDs) with emphasis on the competition effects between the two fields under externally applied pressure and temperature. The electric field is applied along the radial direction of the QD, while the magnetic field is applied along the growth direction. The numerical method we employed in the present calculations is the potential morphing method in the framework of the effective mass approximation. Our results show that the two fields exhibit a competition effect on the donor binding energy, leading to an invariant binding energy as in the zero field case at a critical line. This line separates the region corresponding to the "red shift" of the donor binding energy from the one referring to the "blue shift" of the binding energy. Comparing to the magnetic field effect, increasing in the QD sizes or applied ...

Magnetic freezing is nowadays established as a commercial reality mainly oriented towards the food market. According to advertisements, magnetic freezing is able to generate tiny ice crystals throughout the frozen product, prevent cell destruction, and preserve the quality of fresh food intact after thawing. If all these advantages were true, magnetic freezing would represent a significant advance in freezing technology, not only for food preservation, but also for cryopreservation of biological specimens such as cells, tissues, and organs. Magnetic fields (MFs) are supposed to act directly on water by orientating, vibrating, and/or spinning molecules to prevent them from clustering and, thus, to promote supercooling. However, many doubts exist about the real effects of MFs on freezing and the science behind the potential mechanisms involved. To provide a basis for extending the understanding of magnetic freezing, this paper presents a critical review of the materials published in the literature ...

Over recent years, our working group has implemented the complete data processing chain for PET within the framework of the simulation platform GATE. This contribution has been the backbone of ongoing detector development and also for the complete design of complex systems. In addition to this, simulation is being used extensively during the development of novel fast reconstruction algorithms and, owing to the availability of ever more powerful computing systems (CPU/GPU), even very complex systems can now be simulated under various aspects. This includes the precise consideration and implementation of all physical effects, especially all types of interactions photons undergo in the surrounding material, and also includes the effect of strong magnetic field on the distribution of the positrons in hybrid devices as MR-PET.. For our studies we use the simulation package GATE, which was developed by the OpenGATE Collaboration (http://www.opengatecollaboration.org/home) and is based on GEANT4 (CERN) ...
Context. Capella is among the few binary stars with two evolved giant components. The hotter component is a chromospherically active star within the Hertzsprung gap, while the cooler star is possibly helium-core burning. |BR /| Aims: The known inclination of the orbital plane from astrometry in combination with precise radial velocities will allow very accurate masses to be determined for the individual Capella stars. This will constrain their evolutionary stage and possibly the role of the active stars magnetic field on the dynamical evolution of the binary system. |BR /| Methods: We obtained a total of 438 high-resolution échelle spectra during the years 2007-2010 and used the measured velocities to recompute the orbital elements. Our double-lined orbital solution yields average residuals of 64 m s|SUP|-1|/SUP| for the cool component and 297 m s|SUP|-1|/SUP| for the more rapidly rotating hotter component. |BR /| Results: The semi-amplitude of the cool component is smaller by 0.045 km s|SUP|-1|/SUP|

He checked the density in my breast and said in a nervous voice, "Lets go down the hall and get the mammogram". In a flurry of activity over the next hour, what remains so vivid in my memory was when they snapped the x-ray on the screen. No one needed to tell me what my own eyes saw. It was unmistakable. A child of five could have identified what looked like a snowball that had hit the x-ray, now hanging from the illuminated screen. No denials. No smiling faces. Sadness in the Radiologists eyes; and the color that had drained from the face of the young doctor, just out of med school. I knew. We all knew. Yet astonishingly, I told them it would be okay. I told them not to worry. I knew I would survive. I knew it, as well as I knew my own name. I dont know how, but I did. I could hear it echoing deep inside by body… I would survive, I would survive. ...

My first rabbinic position was as an assistant rabbi…. The rabbi [asked me] to daven Mussaf for the shul on the second day of Rosh ha-Shana. I was flattered… I went home, almost running the whole way, to tell my wife the good news… I immediately began practicing. I got tapes of various chazzanim and spent hours each day memorizing the tunes. I recorded myself so that I could hear how I sounded… My wife was enlisted to listen to Mussaf, over and over again. I had a friend in Yeshiva who was something of a Chazzan, and we spent time on the phone going over each tune I intended on using. In the end, I knew the entire Mussaf by heart, no small feat ...
The present study aims at solving the problem of stagnant water due to receiving of sewage water in a lake at Eastern Jeddah, using state of the art safe techniques. Samples were collected from the lake, then treated using magnetic fields with different intensities in two states, static and shaking, for 30 days. Hence, the physical and chemical properties for samples were measured, in addition to their bacterial content. In both cases of static and shaking, increasing the magnetic flux density caused water clearness, in addition to a relative increase in the pH value and a remarkable decrease in its odor and electric conductivity (EC). In addition, it was observed that lead ions and bacterial content decreased. The study shows that the increasing magnetic field intensity to the level used in this study, accompanied by shacking, is supplemented with the findings of the experiment. It also suggests that the magnetic field plays a major role in finding successful solutions for a lot
A general theory of radio propagation by wave-guide modes is given, which simultaneously makes allowance for the gradualness of the lowest part of the ionosphere, the earths curvature and the earths magnetic field. The method involves solving differential equations satisfied by the matrix admittance or matrix reflexion coefficient variables. The mode condition, excitation factor, and polarization of the waves in a mode are derived by evaluating the residues of a series of poles of a contour integral. The earths curvature is allowed for by the method of the modified refractive index, thus avoiding the use of cumbersome spherical wave functions. This also permits the replacement of a point source by a line source with consequent further simplification of the mathematics. Formulae are given which have been used for computations described elsewhere (Budden & Martin 1962; Martin 1961). ...

- This is complemented by gastro-coronary reflexes whereby the coronary arteries constrict with "functional cardiovascular symptoms" similar to chest-pain on the left side and radiation to the left shoulder, dyspnea, sweating, up to angina pectoris -like attacks with extrasystoles, drop of blood pressure, and tachycardia (high heart beat) or sinus bradycardia (heart beat below 60).

- If you have an ultrasound or sleep study, ensure that you know how to reproduce the symptoms, as it is difficult to detect any abnormalities when symptoms have subsided. (wikipedia.org)
