Anisotropic photoluminescence behaviour of vertical AlGaAs structures grown on gratings | Abstract The formation of vertical AlGaAs quantum wells during MOVPE growth of AlGaAs layers on submicron gratings has been investigated. The influence of the growth temperature, growth velocity, V/III ratio and the overall Al content has been examined and explained using surface diffusion effects of the group III atoms (or reactant species). 77 K PL measurements show a polarization anisotropy and indicate lateral quantum confinement. Also the growth of QWWs on submicron gratings is reported, showing very large PL intensities and polarization anisotropy. Finally the realization of QWWs has been proposed by growing Al x Ga 1- x As/Al y Ga 1- y As QWs on gratings and based on the different surface mobilities of Ga and Al. | We describe the first time on the direct and facile method for noble metal/graphene nanocomposites from graphite without reductants. In our system, the irradiant white-light instead of the chemical reductant exerts the influence on the synthesis of noble metal nanoparticles on graphene. Noble metal salts adsorbed on the surfaces of graphene flakes which were functionalized with ionic surfactants were reduced by irradiation with white light. In particular, noble metal nanoparticles were more evenly distributed on the surface of graphene which was functionalized with SDS than with CTAB. | eng_Latn | 11,800 |
Calculation of an effective pair interaction potential for liquid neon from structure factor measurements | A new approximate theory relating the radial distribution function to the pair interaction potential is applied to the calculation of an effective pair potential for neon by use of the recent structure factor measurements of de Graaf and Mozer (see abstr. A82693 of 1971). The approximation is constrained to reproduce the correct pressure and internal energy. | Abstract This research is focused on the effects of nonlinear terms on the dynamical behavior of graphene reinforced laminated composite plates. Firstly, the governing equations of the graphene reinforced composite thin plate subjected to transverse excitations are derived by using the Hamilton's principle and the von Karman deformation theory. Then numerical method is applied to investigate the nonlinear behaviors of graphene reinforced composite plates. Bifurcation diagram, waveform and phase portrait are demonstrated to analyze the nonlinear dynamics of the graphene reinforced laminated composite plates. Furthermore, the effects of nonlinear terms on the dynamical behavior are discussed in detail, where both the stronger and weaker nonlinear characteristics of lower modes of the plate are presented. Moreover, some interesting phenomena are obtained in numerical simulation. | eng_Latn | 11,801 |
Surface effects on the mechanical behavior of silicon nanowires: Consequence on the brittle to ductile transition at low scale and low temperature | Understanding the origin of the brittle to ductile transition at low scale in Si requires the characterization of the elementary mechanisms governing crack formation or dislocation nucleation. By molecular dynamics simulations, we have investigated the role of three surface states of silicon nanowires (NWs), fresh cut, reconstructed by annealing at 300 K and amorphized, for the activation of plastic mechanisms under tensile and compressive strains. We show that the onset of crack formation identified as wedge-shaped defect on the surface was only observed in fresh-cut NWs in tension. These NWs present high yield strain due to the high symmetry of the surface and the absence of surface defects favoring dislocation nucleation as for the other surface states. This result seems to confirm that the crack formation in nanostructures could be linked to dislocations interactions on intersecting glide planes as experimentally observed rather than direct crack opening. | Abstract We propose a new model which simulates the motion of free electrons in graphene by the evolution of strings on manifolds. In this model, molecules which constitute sheets of graphene are polygonal point-like structures which build ( N + 1 ) -dimensional manifolds. By breaking the gravitational-analogue symmetry of graphene sheets, we show that two separated child sheets and a Chern–Simons bridge are produced giving rise to a wormhole. In this structure, free electrons are transmitted from one child sheet to the other producing superconductivity. An analogue between “effective gravitons” and “Cooper pairs” is found. In principle, this phenomenology provides the possibility to construct superconductor structures by using the analogue of cosmological models. | eng_Latn | 11,802 |
Name the form of carbon considered (early 2000s) the strongest material ever, which having a thickness of one atom has just two dimensions? | nanotechnology - National Geographic Society nanotechnology Photograph by Mark Thiessen, National Geographic Nano-Graffiti In 1989, IBM researchers spelled out their company’s logo using 35 xenon atoms. Twenty years later, researchers at Stanford University spelled out “SU” using sub-atomic particles. The letters were so small they could be used to print the 32-volume Encyclopedia Britannica 2,000 times and the contents would fit on the head of a pin. Investing in Nanotech There are many ways of assessing investment in nanotechnology: government funding of research, venture capital funding of start-ups, or the number of new nanotech companies. These nations have made significant investment in nanotechnology. United States Your fingernails grow about one nanometer every second. When a seagull lands on an aircraft carrier, it sinks about one nanometer. A man’s beard grows about a nanometer between the time he picks up a razor and lifts it to his face. Nano-Cartography In 2010, researchers at IBM used nanotechnology to create a 3-D relief map of the world . . . 1/1000 the size of a grain of salt. Researchers used a sophisticated silicon tip in their microscope to carve into a glass substrate. Nano-Soccer Nanosoccer is an event where computer-driven “nanobots” the size of dust mites challenge one another on fields no bigger than a grain of rice. Often sponsored by government laboratories, nanosoccer teams from all over the world compete in events such as the “RoboCup.” See the rules and results of the 2009 nanosoccer tournament here . Nanotechnology involves the understanding and control of matter at the nanometer-scale. The so-called nanoscale deals with dimensions between approximately 1 and 100 nanometers. A nanometer is an extremely small unit of length—a billionth (10-9) of a meter. Just how small is a nanometer (nm)? A single human hair is about 80,000 to 100,000 nm wide. On the nanometer-scale, materials may exhibit unusual properties. When you change the size of a particle , it can change color, for example. That’s because in nanometer-scale particles, the arrangement of atoms reflects light differently. Gold can appear dark red or purple, while silver can appear yellowish or amber-colored. Nanotechnology can increase the surface area of a material. This allows more atoms to interact with other materials. An increased surface area is one of the chief reasons nanometer-scale materials can be stronger, more durable , and more conductive than their larger-scale (called bulk) counterparts. Nanotechnology is not microscopy . "Nanotechnology is not simply working at ever smaller dimensions," the National Nanotechnology Initiative says. "Rather, working at the nanoscale enables scientists to utilize the unique physical, chemical, mechanical, and optical properties of materials that naturally occur at that scale." Scientists study these properties for a range of uses, from altering consumer products such as clothes to revolutionizing medicine and tackling environmental issues. There are different types of nanomaterials, and different ways to classify them. Natural nanomaterials, as the name suggests, are those that occur naturally in the world. These include particles that make up volcanic ash , smoke, and even some molecules in our bodies, such as the hemoglobin in our blood. The brilliant colors of a peacock’s feathers are the result of spacing between nanometer-scale structures on their surface. Man-made nanomaterials are those that occur from objects or processes created by people. Examples include exhaust from fossil fuel burning engines and some forms of pollution . But while some of these just happen to be nanomaterials—vehicle exhaust, for instance, was not developed as one—scientists and engineer s are working to create them for use in industries from manufacturing to medicine. These are called intentionally produced nanomaterials. Fullerenes and Nanoparticles One way to classify nanomaterials is between fullerenes and nanoparticles. This classification includes both naturally occurring and m | Collecting The Heart Of the Matter by Greene, Graham - First edition identification guide Reviews (1) Graham Greene’s The Heart of the Matter, set in an unnamed West African colony towards the end of World War II, is loosely based on the author’s own experience as a British intelligence officer in Sierra Leone. The novel’s protagonist, Henry Scobie, struggles to make his miserable wife happy. In the process, Scobie begins to wonder if any individual can truly make another happy, resulting in a life-changing moral crisis. The Heart of the Matter, an insightful exploration of pity, suffering, religion, and responsibility, quickly became extremely popular, having sold more than 300,000 copies upon publication. The novel was critically acclaimed and received many favorable reviews. In 1948, The Heart of the Matter was awarded the James Tait Black Memorial Prize for fiction and it was shortlisted for the Best of the James Tait Black awardees in 2012. The novel is ranked 40th on Modern Library’s “100 Best” English-language novels of the 20th century and is also listed on TIME’s “100 Best Novels” (since 1923).

A Diamond as the Steppingstone to New Materials, Using Plasma Physics Technology | Newswise — BIRMINGHAM, Ala. – University of Alabama at Birmingham physicists have taken the first step in a five-year effort to create novel compounds that surpass diamonds in heat resistance and nearly rival them in hardness.
They are supported by a five-year, $20 million National Science Foundation award to create new materials and improve technologies using the fourth state of matter — plasma.
Plasma — unlike the other three states of matter, solid, liquid and gas — does not exist naturally on Earth. This ionized gaseous substance can be made by heating neutral gases. In the lab, Yogesh Vohra, a professor and university scholar in the UAB Department of Physics, uses plasma to create thin diamonds film. Such films have many potential uses, such as coatings to make artificial joints long-lasting or to maintain the sharpness of cutting tools, developing sensors for extreme environments or creating new super-hard materials.
To make a diamond film, Vohra and colleagues stream a mix of gases into a vacuum chamber, heating them with microwaves to create plasma. The low pressure in the chamber is equivalent to the atmosphere 14 miles above the Earth’s surface. After four hours, the vapor has deposited a thin diamond film on its target.
In a paper in the journal Materials, Vohra and colleagues in the UAB College of Arts and Sciences investigated how the addition of boron, while making a diamond film, changed properties of the diamond material.
It was already known that, if the gases are a mix of methane and hydrogen, the researchers get a microcrystalline diamond film made up of many tiny diamond crystals that average about 800 nanometers in size. If nitrogen is added to that gas mixture, the researchers get nanostructured diamond, made up of extremely tiny diamond crystals averaging just 60 nanometers in size.
In the present study, the Vohra team added boron, in the form of diborane, or B 2 H 6 , to the hydrogen/methane/nitrogen feed gas and found surprising results. The grain size in the diamond film abruptly increased from the 60-nanometer, nanostructured size seen with the hydrogen/methane/nitrogen feed gas to an 800-nanometer, microcrystalline size. Furthermore, this change occurred with just minute amounts of diborane, only 170 parts per million in the plasma.
Using optical emission spectroscopy and varying the amounts of diborane in the feed gas, Vohra’s group found that the diborane decreases the amounts of carbon-nitrogen radicals in the plasma. Thus, Vohra said, “our study has clearly identified the role of carbon-nitrogen species in the synthesis of nanostructured diamond and suppression of carbon-nitrogen species by addition of boron to the plasma.”
Since the addition of boron can also change the diamond film from a nonconductor into a semiconductor, the UAB results offer a new control of both diamond film grain size and electrical properties for various applications.
Over the next several years, Vohra and colleagues will probe the use of the microwave plasma chemical vapor deposition process to make thin films of boron carbides, boron nitrides and carbon-boron-nitrogen compounds, looking for compounds that survive heat better than diamonds and also have a diamond-like hardness. In the presence of oxygen, diamonds start to burn at about 1,100 degrees Fahrenheit.
Co-authors with Vohra of the paper, “Morphological transition in diamond thin-films induced by boron in a microwave plasma deposition process,” are Paul A. Baker, Ph.D., UAB Department of Physics, and David R. Goodloe, Birmingham Southern College. Goodloe did summer undergraduate research under a NASA program at UAB.
This work was supported by the National Science Foundation under a cooperative Agreement, OIA-1655280, and a NASA Alabama Space Grant Consortium-Research Experiences for Undergraduates program, NNX15AJ18H. | This week of Off the Shelf has an all-star procurement panel focusing on GSA’s Section 846 Implementation Plan.
Angela Styles, partner at Bracewell LLP, Jonathan Aronie, partner at Sheppard Mullin LLP, and Jon Etherton, president of Etherton & Associates, Inc., share their insights and analysis on the Implementation Plan findings and legislative recommendations.
In particular, the panel takes a close look at the implications of the proposed increase in the Micro Purchase Threshold and GSA’s portal of portals concept.
What key laws would be waived under plan? What is the impact on the procurement system as a whole? What are the next steps? Are the legislative proposals timely or premature? These questions and more are addressed in a wide-ranging, engaging discussion. | eng_Latn | 11,805 |

why are covalent network substances brittle | Because the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids. As solids they do not conduct electricity (again because of the localize electrons).However, they do conduct electricity as liquids (or when dissolved in water) since then the ions can move.istortion away from this geometry can only occur through a breaking of covalent sigma bonds. As a result, the melting point of covalent solids is extremely high. They also tend to be extremely hard substances that will break into pieces rather than smoothly change shape. We say that they are stiff and brittle. | A network solid or covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. Hardness: Very hard, due to the strong covalent bonds throughout the lattice (deformation can be easier, however, in directions that do not require the breaking of any covalent bonds, as with flexing or sliding of sheets in graphite or mica). | eng_Latn | 11,856 |

what do carbon atoms link together to form in fullerenes | Structure of a buckminsterfullerene molecule - a large ball of 60 atoms. Buckminster Fullerene is one type of fullerene. Fullerenes are made from carbon atoms joined together to make balls, âcagesâ or tubes of carbon. The molecules of Buckminster Fullerene are spherical and are also known as 'buckyballs' â formula C60. | Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in an hexagonal lattice.

what is graphites | Graphite (pronunciation: /ËÉ¡ræfaɪt/), archaically referred to as plumbago, is a crystalline form of carbon, a semimetal, a native element mineral, and one of the allotropes of carbon. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. | Graphite is an interesting material, an allotrope of carbon (as is diamond). It displays properties of both metals, and nonmetals. However, like a metal, graphite is a very good conductor of electricity due to the mobility of the electrons in its outer valence shells. | eng_Latn | 11,859 |

A review of the medical literature was carried out to determine guidelines for cost-effective and safe use of chest radiography in the emergency department. Screening radiographs are indicated in specific populations in the search for occult tuberculosis or carcinoma and in routine or preoperative cases. Radiography is clinically indicated in the asthmatic patient, the elderly patient, and the symptomatic patient, and its indications are modified by the patient's age and presenting signs and symptoms. Based on the information reviewed, rational guidelines for the use of chest radiography are presented. | PURPOSE ::: To assess the yield of chest radiography among a group of symptomatic adults presenting to a walk-in clinic. ::: ::: ::: PATIENTS AND METHODS ::: Outpatients presenting to a walk-in clinic for evaluation of cough, shortness of breath, or pleuritic chest pain were interviewed by nurses who recorded clinical data pertaining to the present illness and past medical history. Chest radiographs were then obtained prior to physician evaluation. ::: ::: ::: RESULTS ::: A total of 221 patients were enrolled in the study; 97% were men and the mean age was 62 (+/- 10.3) years. New clinically important radiographic abnormalities, defined as those necessitating acute intervention and/or follow-up evaluation, were identified for 77 (34.8%) of the 221 patients studied. Abnormalities included 39 (17.6%) cases of infiltrates, 23 (10.4%) cases of nodules or mass lesions, and 19 (8.6%) cases of cardiomegaly or congestive heart failure. Evaluation of clinical data obtained during the triage interview revealed no statistically significant difference between those patients with and those without new radiographic abnormalities on their chest x-rays. ::: ::: ::: CONCLUSION ::: Adult patients similar to those described in this study who present to a walk-in clinic with a chief complaint of cough, dyspnea, or pleuritic chest pain have a high likelihood of having new clinically important abnormalities found on their chest radiographs. Since patient characteristics did not predict which patients were more likely to have abnormal findings, the practice of obtaining chest radiographs for such individuals at the time of triage and prior to physician evaluation appears justified. | Blunt trauma abdomen rarely leads to gastrointestinal injury in children and isolated gastric rupture is even rarer presentation.

Disappearing signs of acute myocardial infarction in a patient with viral myocarditis. | A case of acute viral myocarditis with the rapid appearance and disappearance of clinical, laboratory, electrocardiographic, and vectorcardiographic signs of acute myocardial infarction is described in this report. Although segmentary alterations in contractility were demonstrated by ventriculography, coronary angiography revealed normal coronary arteries. | Recent advances in endoscopic surgical equipment, video monitoring, and endoscopic surgical techniques have expanded the application of thoracoscopic surgery to pulmonary resection. One of the major limitations of this technique is the difficulty in identifying invisible pulmonary nodules in which manual palpation is not possible. To resolve this problem, we employed intraoperative intrathoracic ultrasonography during video-assisted thoracoscopic pulmonary resection. We conclude that intraoperative ultrasonography during thoracoscopic pulmonary resection is useful to identify pulmonary nodules, except inflammatory lesions. | eng_Latn | 11,868 |
Care of patients with apparently asymptomatic severe aortic valve stenosis. | Although most asymptomatic patients with aortic stenosis (AS) have an excellent prognosis with observation only, some patients with severely stenotic aortic valves in the absence of symptoms may benefit from early intervention.

In literature there is no clear consensus about the diagnosis and treatment. We present a case of a 47 year old man who was diagnosed with slipping rib syndrome after a cycling incident 8 years ago. Also, we developed a flow chart according the diagnostic and therapeutic steps in the treatment of slipping rib syndrome.

Medically, what is affected by Myositis? | Myositis: Symptoms and Causes Cocaine Alcohol Myopathy may occur right after starting a medication, or may occur after taking a drug for months or years. Sometimes it is caused by an interaction between two different medications. Severe myositis caused by medications is rare. Injury. Vigorous exercise can lead to muscle pain , swelling, and weakness for hours or days after a workout . Inflammation contributes to these symptoms, technically making this a form of myositis. Myositis symptoms after exercise or injury nearly always resolve completely with rest and recovery. Rhabdomyolysis . Rhabdomyolysis occurs when muscles break down quickly. Muscle pain , weakness, and swelling are symptoms of rhabdomyolysis. Urine may also turn a dark brown or red color. Symptoms of Myositis The main symptom of myositis is muscle weakness. The weakness may be noticeable or may only be found with testing. Muscle pain (myalgias) may or may not be present. Continued Dermatomyositis , polymyositis, and other inflammatory myositis conditions tend to cause weakness that gets worse slowly over weeks or months. The weakness affects large muscle groups, including the neck, shoulders, hips, and back. Muscles on both sides are usually affected. The weakness from myositis can lead to falls and make it difficult to get up from a chair or after a fall. Other symptoms that may be present with inflammatory conditions include: Thickening of the skin on the hands Difficulty swallowing Difficulty breathing People with myositis caused by a virus usually have symptoms of a viral infection , such as runny nose , fever , cough and sore throat , or nausea and diarrhea . But the symptoms of viral infection may go away days or weeks before myositis symptoms begin. Some people with myositis have muscle pain, but many do not. Most muscle pain is not caused by myositis, but by strain injuries, or ordinary illnesses like colds and flu . These and other ordinary muscle pains are called myalgias. Diagnosis of Myositis A doctor may suspect myositis based on a person’s symptoms of muscle weakness or other evidence of myositis. Tests for myositis include: Blood tests. High levels of muscle enzymes, such as creatine kinase , may mean there is muscle inflammation. Other blood tests check for abnormal antibodies that may identify an autoimmune condition. MRI scan. A scanner using a high-powered magnet and a computer creates images of the muscles. An MRI scan can help identify areas of myositis and changes in the muscles over time. EMG. By inserting needle electrodes into muscles, a doctor can test the response of muscles to electrical nerve signals. EMG can identify muscles that are weak or damaged by myositis. Muscle biopsy . This is the most accurate test for diagnosing myositis. A doctor identifies a weak muscle, makes a small incision, and removes a small sample of muscle tissue for testing. Muscle biopsy leads to a final diagnosis in most people with myositis. There are many causes of muscle weakness and pain more common than myositis, and testing for myositis is not a straightforward process. For these reasons, the process of diagnosing myositis can be long.

Bulk up with knowledge via Groupon’s intro to isometrics. Charles Atlas, the mail-order fitness king, made his famous transformation from 97-pound weakling to “The World’s Most Perfectly Developed Man” partly by standing stock-still. In his system of self-perfection, he often used moves that pitted muscle against muscle without moving the joints, which is also known as isometrics. These kinds of exercises were ideal during the Great Depression because they required little to no equipment. Press your palms together, hold a plank position, push against a wall, or flex your biceps and you’re increasing tension and placing beneficial stress on your muscle fibers even though you’re not going anywhere. You’re also not requiring much from your joints, tendons, or connective tissue, so isometrics can be an excellent way to maintain muscle even while recovering from an injury or a career as human pretzel. People with arthritis who experience pain with movement can also find them beneficial. Because they involve holding one position, isometric exercises are tightly targeted on relatively small sections of muscle. For that reason, you probably won’t find a strength-training program that relies on isometric moves alone—in order to develop strength across your entire range of motion, you need to stress the muscle at every angle.

What is the most common symptom of MI? | The onset of symptoms in myocardial infarction (MI) is usually gradual, over several minutes, and rarely instantaneous. Chest pain is the most common symptom of acute MI and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischemia (a lack of blood and hence oxygen supply) of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen, where it may mimic heartburn. Levine's sign, in which a person localizes the chest pain by clenching their fists over their sternum, has classically been thought to be predictive of cardiac chest pain, although a prospective observational study showed it had a poor positive predictive value. | For the finals, American Idol debuted a new state-of-the-art set and stage on March 11, 2008, along with a new on-air look.

Once the decision is made to proceed with surgery, choices regarding the type of artificial valve (prosthesis) used should be considered. In broad terms there are two types of artificial valves or prostheses: mechanical valves and biological valves. | My advice is to see a doctor to see if they can come out.

i keep fracturing rib bones while playing racquetball (which i've played for 25 years) i'm 50 yr what can i do | Do you have osteoporosis? Some people loose calcium and bone mass density. They get what is called a "pathological fracture". This can happen just with strenuous exercise. I'd ask your doctor if a bone density test is right for you. Medications can be given to replace calcium AND prevent calcium loss, if this is the problem. (Can affect both women AND men) | See a doctor, and request a second opinion from a cardiologist. Doctors tend to dismiss healthy-looking young people as being hypochondriacs or just panic attacks, when it could be a simple heart condition treated with medication. Insist on seeing a cardiologist and/or having an echocardiogram - NOT an EKG, which will not detect valve problems.\n\nIt could be panic attacks, could be mitral valve prolapse. Either way, see a doctor because both are easily fixable and there is no reason for an otherwise healthy young lady to suffer. | eng_Latn | 11,876 |
Ive been going to the gym and for the past few days everything has gone fine, i see chest rising and chest hurting after workouts but recently, ive been doing the same workout and chest didnt hurt after 2nd or 3rd workout, so i increased the load and worked more effectively but only my arms seem to tire out and when i contract my chest with my arms it doesnt feel hurting whats wrong with me??\nBy the way i eat lots of protein and calcium^^ i am 15 nearly 16 | if you work out everyday then you almost become immune to it. so leave a day between workouts, then next time you go, increase the load but go slower and do fewer reps at a time. and really take your time doing it to get the most out of each rep. ita about quality not quantity. make sure you warm up too. | She should make an appointment to see her physician as soon as possible. Based upon the limited range of motion of her arm and where you describe the pain, it sounds very likely that she may have torn her rotator cuff. The primary muscle of the rotator cuff is the supraspinatus muscle and when it is torn completely, you can seldom lift the arm very high. Many people tear this muscle with no identified trauma and if she has had chronic shoulder problems this is even more likely. Also, if the rotator cuff is not torn, she may have a frozen shoulder "adhesive capsulitis". This problem usually onsets in females between the ages of say 45-65 and is highly prevalent with people who have diabetes but can occur with anyone. Usually a frozen shoulder is slow to onset but I have had many patients that have had onset over night. Regardless of the information I have given you, the first thing you should do is set up an appointment to see your physician. A formal diagnosis should be made only after a thorough orthopedic evaluation as there are many conditions that could case the symptoms that you describe. | eng_Latn | 11,877 |

The swelling is about the size of a golf ball. If I squish it, it dissappears for awhile, but always comes back. It appears to have been the cause of a few stomach aches (ie. If something rubs against it, while I have a stomach ache, it will cause even more pain, and once it actually felt like it was what caused me to vomit). So it might be linked to my stomach in some way, but I can't say for sure. | not being i a position to know whether you might have been injured in the testicle or to examine it, I cannot say exactly what it might be. Hoiwever, when dealing with lumps or swellings in such a sensitive area one should tend to consult their doctor and have it examined.

when it does hurt it hurts to breath, the doctor said it was just inflammation, but would that hurt this much-i have not injured the area either-today it hurt from my left rib area into my chest-i have had ekg's and my heart is good what could this sharp stupid pain be? | Sounds like the doc said, an inflamation, maybe caused by an infection. I've had it a few times, but normally following a rib injury, which does not have to be major. You don't breathe properly, or cough, so the air in the bottom of the lungs gets stagnant. | Working out to the point of being in pain is not good. Lifting until you can't lift any more is not good for the muscles. You are doing more damage that building. Your body uses the nutrients it needs to build muscle to heal the pain. \n\nIT is true that the muscle needs to reast before it lifts again. If you give your muscle a minute to rest between sets you'll be able to lift the same amount of weight more reps. \n\nIf your 'HUBBY' is trying to bulk up and is already in shape try superlifting. You start with the max weight and lift till you can't any more. Then drop the weight five or ten pounds. Lift that until you can't. Repeat process. This will use all of your muscle and build it up.

If it is interfering with your ability to get a good breathe though, you really should go have it checked out by the doctor. Even as an asthmatic, you should not need to take deep breaths constantly to avoid feeling breathless. Like as not it is just simply a pulled or strained muscle, but you might also benefit from something to ease your need to breathe so deeply so often.

Also was the pain in my neck related to the exercise or could it have been my heart, as i have this pain after i have chest pain. | Was this a "self test" or one supervised by a doctor or cardiologist? If it's a self test I would advise you to see a doctor before getting on a treadmill again. In fact, see a doctor anyway. That's a very high blood pressure. An increase in diastolic blood pressure of more than 10 mmHg (optimal is <120) during or after exercise represents an unstable form of hypertension, and may be associated with coronary artery disease. At 236 you could be classified as well above third stage hypertension. Really, see a doctor. | Na you just probably pulled a muscle.

It seemed to stop the fluttering. Have you heard of that before? | I have never heard of any treatments for MVP. I used to take medication to stop the racing and minimize the fluttering but as far as I had been told there was no other treatment other than possible surgery if it were bad enough (mine wasn't). Only other advice I was given was to avoid caffeine and not to worry about the MVP b/c it would not really affect much of anything. | get rid of the carpet? cover the metal? wear antishock bracelets? find some way to nuetralize yourself when you enter? | eng_Latn | 11,896 |
case study - swelling in the face, tried benadryl-no impact, went to emergency room, has dyspnoea on exertion, had full blood panel for kidneys, lungs and heart, hepatobiliary, urinalysis, ekg, heart failure, CPC, chest x-ray - all these tests came back negative... took diuretic and lost 4 lbs in 24 hrs, hints: this test can't be done at emergency care center, and requires no blood work, performed in a "special" place, and patient has to be put in condition that mimicks symptoms (test challenges body) Which cardiovascular-related test is next? | You want to a do a stress echocardiogram which is a specialized version of a stress test - it can be done either chemically or on a treadmill. The echocardiogram would give you information about the contractility of the heart muscle, both at rest and with stress; and the valvular function as well as pulmonary pressures which all could be implicated in the symptoms described. You did not mention the age of the patient in your case, so I wouldn't further hazard a guess on the etiology of the symptoms. | You will have to check with your doctor.

Muscle spasms under ribs while tapering off prednisone? | Normal ! This is normal when tapering off of this steroid. The problem is, you need to go back up an increment so that the muscle spasms stop. I would contact your dr and tell him that you're going through Prednisone Withdrawl Symptoms. He will or at least SHOULD, up your dosage just a very small bit, so that the spasms go away. Then you need to taper off SLOWER than before or you will end up with spasms in other parts of your body. I had this trouble years ago, and the muscle spasms were so bad that I needed help from my mom to be able to sit on the toilette. Horrible experience. Also, try drinking anything with calcium in it and also eat bannanas. | Type the name of your state and offical website into your search engine (florida official website).

why does my chest hurt and nose sting whenever I run or jog? | where do you live? It IS winter and the air could be pretty cold and dry which will hurt in your mose when you breath hard.

Monitor yourself carefully, it might or might not be anything. | dont worry that's not you, exactly. it's a demon named sexazel. he lives inside you. if you wanna get rid of him find a NY hooker named esmeralda. she's not really a hooker but an exorcist. hope this helps | eng_Latn | 11,899 |
