Nitric oxide inhibits cardiac energy production via inhibition of mitochondrial creatine kinase. (1/1169)
Nitric oxide biosynthesis in cardiac muscle leads to a decreased oxygen consumption and lower ATP synthesis. It is suggested that this effect of nitric oxide is mainly due to the inhibition of the mitochondrial respiratory chain enzyme, cytochrome c oxidase. However, this work demonstrates that nitric oxide is able to inhibit soluble mitochondrial creatine kinase (CK), mitochondrial CK bound in purified mitochondria, CK in situ in skinned fibres as well as the functional activity of mitochondrial CK in situ in skinned fibres. Since mitochondrial isoenzyme is functionally coupled to oxidative phosphorylation, its inhibition also leads to decreased sensitivity of mitochondrial respiration to ADP and thus decreases ATP synthesis and oxygen consumption under physiological ADP concentrations. (+info)Separation of urea, uric acid, creatine, and creatinine by micellar electrokinetic capillary chromatography with sodium cholate. (2/1169)
The capillary electrophoretic separation of the four nonprotein nitrogenous compounds (NPNs; urea, uric acid, creatine, and creatinine) typically employed in clinical and medical settings for the monitoring of renal function is described. Successful resolution of these compounds is achieved with the use of a bile salt micelle system composed of sodium cholate at phosphate buffer pH 7.4. The elution patterns of four NPNs are obtained within 30 min with a voltage of 30 kV. The effect of varying the applied voltage, temperature, and the mole ratio of phosphate buffer with bile salt surfactant on the migration behavior is also examined. (+info)Shortening of muscle relaxation time after creatine loading. (3/1169)
The effect of creatine (Cr) supplementation on muscle isometric torque generation and relaxation was investigated in healthy male volunteers. Maximal torque (Tmax), contraction time (CT) from 0.25 to 0.75 of Tmax, and relaxation time (RT) from 0.75 to 0.25 of Tmax were measured during 12 maximal isometric 3-s elbow flexions interspersed by 10-s rest intervals. Between the pretest and the posttest, subjects ingested Cr monohydrate (4 x 5 g/day; n = 8) or placebo (n = 8) for 5 days. Pretest Tmax, CT, and RT were similar in Cr and placebo groups. Also in the posttest, Tmax and CT were similar between groups. However, posttest RT was decreased consistently by approximately 20% (P < 0.05) in the Cr group from the first to the last of the 12 contractions. In addition, the mean decrease in RT after Cr loading was positively correlated with pretest RT (r = 0.82). It is concluded that Cr loading facilitates the rate of muscle relaxation during brief isometric muscle contractions without affecting torque production. (+info)Absolute quantification of brain metabolites by proton magnetic resonance spectroscopy in normal-appearing white matter of multiple sclerosis patients. (4/1169)
The aim of this research was to obtain an absolute quantification of the N-acetyl-aspartate, choline, creatine and phosphocreatine levels in normal-appearing white matter by means of 1H magnetic resonance spectroscopy in a group of multiple sclerosis patients (27 with the relapsing-remitting form and 13 with the secondary progressive form). These values were compared with those of a group of 12 age-matched healthy control subjects. A significant decrease in the N-acetyl-aspartate concentration was found in normal-appearing white matter of frontal and parietal brain areas in multiple sclerosis patients compared with the same areas in control subjects. This reduction was more evident in progressive patients. The decrease in the N-acetyl-aspartate concentration in normal-appearing white matter significantly correlated with the Expanded Disability Status and the lesional load. No significant change was found in the concentration of creatine or choline. This finding concurs with previous evidence of heterogeneity in the multiple sclerosis pathological process which is not confined to the lesions and involves not only myelin, but also axons, even in white matter which appears normal on MRI. (+info)Efficiency of oxidative phosphorylation and energy dissipation by H+ ion recycling in rat-liver mitochondrial metabolizing pyruvate. (5/1169)
A method was developed for the calculation of metabolic fluxes through individual enzymatic reactions of pyruvate metabolism including the citric acid cycle in rat liver mitochondrial incubated at metabolic states between state 4 and state 3. This method is based on the measurement of the specific radioactivities of the products formed from [2-14C]pyruvate. With this procedure the energy balance of mitochondria incubated in the presence of [2-14C]pyruvate, ATP, bicarbonate and phosphate at different ATP/ADP ratios in the medium was calculated. The ATP/ADP ratios were maintained at a steady state with creatine kinase plus creatine as a phosphoryl acceptor. The calculations revealed that by adding increasing concentrations of creatine up to 20 mM the energy dissipated by the mitochondria decreased but showed a local maximum at 13mM creatine. Omission of bicarbonate from the medium led to a shift of this maximum. When energy dissipation was minimal the overall P/O ratio was maximal. The amount of energy dissipated was paralleled by the magnitude of the pH gradient across the inner membrane. From these results it was concluded that the recycling of H+ ions which consists of a passive leakage of H+ ions into the matrix and an active extrusion of these ions out of this compartment, is an important energy dissipating process. The H+ ion recycling is thus one of the processes which give rise to the state 4 respiration in mitochondria. (+info)Cerebral metabolic abnormalities in congestive heart failure detected by proton magnetic resonance spectroscopy. (6/1169)
OBJECTIVES: Using proton magnetic resonance spectroscopy, we investigated cerebral metabolism and its determinants in congestive heart failure (CHF), and the effects of cardiac transplantation on these measurements. BACKGROUND: Few data are available about cerebral metabolism in CHF. METHODS: Fifty patients with CHF (ejection fraction < or = 35%) and 20 healthy volunteers were included for this study. Of the patients, 10 patients underwent heart transplantation. All subjects performed symptom-limited bicycle exercise test. Proton magnetic resonance spectroscopy (1H MRS) was obtained from localized regions (8 to 10 ml) of occipital gray matter (OGM) and parietal white matter (PWM). Absolute levels of the metabolites (N-acetylaspartate, creatine, choline, myo-inositol) were calculated. RESULTS: In PWM only creatine level was significantly lower in CHF than in control subjects, but in OGM all four metabolite levels were decreased in CHF. The creatine level was independently correlated with half-recovery time and duration of heart failure symptoms in PWM (r = -0.56, p < 0.05), and with peak oxygen consumption and serum sodium concentration in OGM (r = 0.58, p < 0.05). Cerebral metabolic abnormalities were improved after successful cardiac transplantation. CONCLUSIONS: This study shows that cerebral metabolism is abnormally deranged in advanced CHF and it may serve as a potential marker of the disease severity. (+info)Effect of thrombin inhibition in vascular dementia and silent cerebrovascular disease. An MR spectroscopy study. (7/1169)
BACKGROUND AND PURPOSE: Silent cerebrovascular disease (CVD) has been proposed as a predisposing condition for clinically overt stroke and vascular dementia. Recently, we found increased thrombin generation in silent CVD patients. Here, we report the effect of thrombin inhibition using a potent selective thrombin inhibitor on the cerebral metabolism and function in peripheral arterial occlusive disease (PAOD) patients with or without silent CVD. METHODS: We examined 17 mild chronic PAOD patients, including 2 cases of vascular dementia. We divided the patients into 2 groups: 1 was the advanced CVD group with multiple lacunar infarction and/or advanced periventricular hyperintensity detected by brain MRI (n=12), and the other was the no CVD group that had none of these abnormalities (n=5). We assessed the cerebral biochemical compounds in the deep white matter area and cerebellar hemisphere (8 cm3) by proton MR spectroscopy before and after infusion of argatroban (10 mg/d IV) over 2 hours for 7 days. RESULTS: The ratio of N-acetylasparate (NAA) to total creatine (Cre) in the deep white matter area was significantly lower in the advanced CVD group than in the no CVD group, whereas there were no significant differences in this ratio in the cerebellar hemisphere between the 2 groups. In the former group, this decreased NAA/Cre ratio significantly increased after argatroban therapy, whereas there was no change in the latter group. The 2 patients with vascular dementia showed clinical improvement with marked increases in the NAA/Cre ratio and mini-mental score. CONCLUSIONS: These results suggest that increased thrombin generation may have some pathophysiological roles in developing vascular dementia and its chronic predisposing conditions. Thrombin inhibition may break this vicious cycle and lead to clinical improvement. (+info)Proton MR spectroscopy in patients with complex partial seizures: single-voxel spectroscopy versus chemical-shift imaging. (8/1169)
BACKGROUND AND PURPOSE: Proton MR spectroscopy has recently been applied to the evaluation of seizures, but few comparisons have been made between different clinical spectroscopic techniques. Our goal was to determine whether there is a significant difference between hippocampal NAA/(Cho+Cr) ratios obtained by single-voxel spectroscopy (SVS) and by chemical-shift imaging (CSI). METHODS: Twelve healthy adults and eight patients with complex partial seizures were studied on a 1.5-T MR scanner using a proton SVS method. Another 12 healthy adults and 10 patients with complex partial seizures were recruited for a proton CSI study, which was performed on a different 1.5-T MR system. The NAA/(Cho+Cr) ratio was calculated from the integral peak areas by curve fitting. The two-tailed t-test was used for statistical analysis. RESULTS: The mean value +/- standard deviation of the hippocampal NAA/(Cho+Cr) ratio in healthy control subjects was 0.63 +/- 0.07 by SVS, with 0.62 +/- 0.15 for the anterior hippocampus and 0.65 +/- 0.11 for the posterior hippocampus by CSI. There was no significant difference between the control group data obtained by SVS and those by CSI, nor was there a regional difference in the CSI NAA/(Cho+Cr) ratio in the hippocampus. Relative to the control group, the patients with seizures had a significant decrease in the NAA/(Cho+Cr) ratio in the abnormal hippocampus: -28% by SVS, and -24% in the anterior hippocampus and -18% in the posterior hippocampus by CSI. Proton SVS and CSI detected hippocampal abnormalities, unilateral or bilateral, in all patients of each group. CONCLUSION: Under similar measurement conditions, proton SVS and CSI provide similar NAA/(Cho+Cr) ratios among healthy control subjects, and they possess comparable ability for detecting hippocampal abnormalities in patients with complex partial seizures. (+info)Rhabdomyolysis can be caused by a variety of factors, including:
1. Physical trauma or injury to the muscles
2. Overuse or strain of muscles
3. Poor physical conditioning or training
4. Infections such as viral or bacterial infections that affect the muscles
5. Certain medications or drugs, such as statins and antibiotics

In severe cases, hospitalization may be necessary to monitor and treat complications such as kidney failure or cardiac problems.
1. Muscular dystrophy: A group of genetic disorders characterized by progressive muscle weakness and degeneration.
2. Myopathy: A condition where the muscles become damaged or diseased, leading to muscle weakness and wasting.
3. Fibromyalgia: A chronic condition characterized by widespread pain, fatigue, and muscle stiffness.
4. Rhabdomyolysis: A condition where the muscle tissue is damaged, leading to the release of myoglobin into the bloodstream and potentially causing kidney damage.
5. Polymyositis/dermatomyositis: Inflammatory conditions that affect the muscles and skin.
6. Muscle strain: A common injury caused by overstretching or tearing of muscle fibers.
7. Cervical dystonia: A movement disorder characterized by involuntary contractions of the neck muscles.

9. Oculopharyngeal myopathy: A condition characterized by weakness of the muscles used for swallowing and eye movements.
10. Inclusion body myositis: An inflammatory condition that affects the muscles, leading to progressive muscle weakness and wasting.
These are just a few examples of the many different types of muscular diseases that can affect individuals. Each condition has its unique set of symptoms, causes, and treatment options. It's important for individuals experiencing muscle weakness or wasting to seek medical attention to receive an accurate diagnosis and appropriate care.
1. Polymyositis: This is an inflammatory disease that affects the muscles and can cause muscle weakness, pain, and stiffness.
2. Dercum's disease: This is a rare condition that causes fatty degeneration of the muscles, leading to muscle pain, weakness, and wasting.
3. Inflammatory myopathy: This is a group of conditions that cause inflammation in the muscles, leading to muscle weakness and pain.
4. Dermatomyositis: This is an inflammatory condition that affects both the skin and the muscles, causing skin rashes and muscle weakness.
5. Juvenile myositis: This is a rare condition that affects children and can cause muscle weakness, pain, and stiffness.
The symptoms of myositis can vary depending on the type of condition and its severity. Common symptoms include muscle weakness, muscle pain, stiffness, and fatigue. Other symptoms may include skin rashes, fever, and joint pain.
The diagnosis of myositis typically involves a combination of physical examination, medical history, and laboratory tests such as blood tests and muscle biopsies. Treatment for myositis depends on the underlying cause and may include medications such as corticosteroids, immunosuppressive drugs, and physical therapy. In some cases, surgery may be necessary to remove affected muscle tissue.
There are several types of muscular dystrophies, including:
1. Duchenne muscular dystrophy (DMD): This is the most common form of muscular dystrophy, affecting males primarily. It is caused by a mutation in the dystrophin gene and is characterized by progressive muscle weakness, wheelchair dependence, and shortened lifespan.
2. Becker muscular dystrophy (BMD): This is a less severe form of muscular dystrophy than DMD, affecting both males and females. It is caused by a mutation in the dystrophin gene and is characterized by progressive muscle weakness, but with a milder course than DMD.
3. Limb-girdle muscular dystrophy (LGMD): This is a group of disorders that affect the muscles around the shoulders and hips, leading to progressive weakness and degeneration. There are several subtypes of LGMD, each with different symptoms and courses.
4. Facioscapulohumeral muscular dystrophy (FSHD): This is a rare form of muscular dystrophy that affects the muscles of the face, shoulder, and upper arm. It is caused by a mutation in the D4Z4 repeat on chromosome 4.
5. Myotonic dystrophy: This is the most common adult-onset form of muscular dystrophy, affecting both males and females. It is characterized by progressive muscle stiffness, weakness, and wasting, as well as other symptoms such as cataracts, myotonia, and cognitive impairment.
There is currently no cure for muscular dystrophies, but various treatments are available to manage the symptoms and slow the progression of the disease. These include physical therapy, orthotics and assistive devices, medications to manage pain and other symptoms, and in some cases, surgery. Researchers are actively working to develop new treatments and a cure for muscular dystrophies, including gene therapy, stem cell therapy, and small molecule therapies.
It's important to note that muscular dystrophy can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner, depending on the specific type of dystrophy. This means that the risk of inheriting the condition depends on the mode of inheritance and the presence of mutations in specific genes.
In summary, muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. There are several types of muscular dystrophy, each with different symptoms and courses. While there is currently no cure for muscular dystrophy, various treatments are available to manage the symptoms and slow the progression of the disease. Researchers are actively working to develop new treatments and a cure for muscular dystrophy.
Here are some possible causes of myoglobinuria:
1. Muscle injury or trauma: This can cause myoglobin to leak into the bloodstream and then into the urine.
2. Muscle disease: Certain muscle diseases, such as muscular dystrophy, can cause myoglobinuria.
3. Kidney damage: Myoglobin can accumulate in the kidneys and cause damage if the kidneys are not functioning properly.
4. Sepsis: Sepsis is a systemic infection that can cause muscle breakdown and myoglobinuria.
5. Burns: Severe burns can cause muscle damage and lead to myoglobinuria.
6. Heart attack: A heart attack can cause muscle damage and myoglobinuria.
7. Rhabdomyolysis: This is a condition where the muscles break down and release myoglobin into the bloodstream. It can be caused by various factors such as medication, infection, or injury.
Symptoms of myoglobinuria may include dark urine, proteinuria (excess protein in the urine), and kidney damage. Treatment depends on the underlying cause and may involve supportive care, medication, or dialysis to remove waste products from the blood.
MRI can occur in various cardiovascular conditions, such as myocardial infarction (heart attack), cardiac arrest, and cardiac surgery. The severity of MRI can range from mild to severe, depending on the extent and duration of the ischemic event.
The pathophysiology of MRI involves a complex interplay of various cellular and molecular mechanisms. During ischemia, the heart muscle cells undergo changes in energy metabolism, electrolyte balance, and cell membrane function. When blood flow is restored, these changes can lead to an influx of calcium ions into the cells, activation of enzymes, and production of reactive oxygen species (ROS), which can damage the cells and their membranes.
The clinical presentation of MRI can vary depending on the severity of the injury. Some patients may experience chest pain, shortness of breath, and fatigue. Others may have more severe symptoms, such as cardiogenic shock or ventricular arrhythmias. The diagnosis of MRI is based on a combination of clinical findings, electrocardiography (ECG), echocardiography, and cardiac biomarkers.
The treatment of MRI is focused on addressing the underlying cause of the injury and managing its symptoms. For example, in patients with myocardial infarction, thrombolysis or percutaneous coronary intervention may be used to restore blood flow to the affected area. In patients with cardiac arrest, cardiopulmonary resuscitation (CPR) and other life-saving interventions may be necessary.
Prevention of MRI is crucial in reducing its incidence and severity. This involves aggressive risk factor management, such as controlling hypertension, diabetes, and dyslipidemia, as well as smoking cessation and stress reduction. Additionally, patients with a history of MI should adhere to their medication regimen, which may include beta blockers, ACE inhibitors or ARBs, statins, and aspirin.
In conclusion, myocardial injury with ST-segment elevation (MRI) is a life-threatening condition that requires prompt recognition and treatment. While the clinical presentation can vary depending on the severity of the injury, early diagnosis and management are crucial in reducing morbidity and mortality. Prevention through aggressive risk factor management and adherence to medication regimens is also essential in preventing MRI.
Glycosuria can also occur in healthy individuals who consume a diet high in sugar or refined carbohydrates, but this is not considered a pathological condition. In contrast, renal glycosuria is a sign of underlying kidney dysfunction and may be indicative of more severe complications if left untreated.
1. Duchenne muscular dystrophy: This is the most common form of muscular dystrophy in children, caused by a defect in the DMD gene that codes for dystrophin protein. It affects boys primarily and can lead to progressive muscle weakness and wasting, as well as cardiac and other complications.
2. Becker muscular dystrophy: This is a milder form of muscular dystrophy than Duchenne, caused by a defect in the DMD gene that codes for dystrophin protein. It primarily affects boys but can also affect girls.
3. Limb-girdle muscular dystrophy: This is a group of disorders characterized by progressive muscle weakness and degeneration, particularly affecting the shoulder and pelvic girdles. There are several types of limb-girdle muscular dystrophy, including type 1A, 1B, 2A, and 2B.
4. Facioscapulohumeral muscular dystrophy: This is a type of muscular dystrophy that affects the muscles of the face, shoulder blades, and upper arms. It can cause progressive muscle weakness, wasting, and fatigue.
5. Myotonic muscular dystrophy: This is the most common form of adult-onset muscular dystrophy, caused by a defect in the DMPK gene that codes for myotonia protein. It can cause progressive muscle stiffness, spasms, and weakness, as well as other complications such as cataracts and type 2 diabetes.
In animals, muscular dystrophy is similar to human forms of the disorder, caused by genetic mutations that affect muscle function and strength. It can be caused by a variety of factors, including genetics, nutrition, and environmental exposures.
Symptoms of muscular dystrophy in animals can include:
1. Progressive muscle weakness and wasting
2. Loss of coordination and balance
3. Difficulty walking or running
4. Muscle cramps and spasms
5. Poor appetite and weight loss
6. Increased breathing rate and difficulty breathing
7. Cardiac problems, such as arrhythmias and heart failure
8. Cognitive decline and seizures
Diagnosis of muscular dystrophy in animals is similar to human patients, involving a combination of physical examination, medical history, and diagnostic tests such as blood tests, imaging studies, and muscle biopsy.
Treatment for muscular dystrophy in animals is limited, but may include:
1. Supportive care, such as antibiotics for respiratory infections and pain management
2. Physical therapy to maintain joint mobility and prevent deformities
3. Nutritional support to ensure adequate nutrition and hydration
4. Medications to manage symptoms such as muscle spasms and seizures
5. Assistive devices, such as wheelchairs or slings, to improve mobility and quality of life
Prevention of muscular dystrophy in animals is not possible at present, but research into the genetic causes and potential treatments for the disease is ongoing. It is important for pet owners to be aware of the signs of muscular dystrophy and seek veterinary care if they suspect their pet may be affected.
Myocardial ischemia can be caused by a variety of factors, including coronary artery disease, high blood pressure, diabetes, and smoking. It can also be triggered by physical exertion or stress.
There are several types of myocardial ischemia, including:
1. Stable angina: This is the most common type of myocardial ischemia, and it is characterized by a predictable pattern of chest pain that occurs during physical activity or emotional stress.
2. Unstable angina: This is a more severe type of myocardial ischemia that can occur without any identifiable trigger, and can be accompanied by other symptoms such as shortness of breath or vomiting.
3. Acute coronary syndrome (ACS): This is a condition that includes both stable angina and unstable angina, and it is characterized by a sudden reduction in blood flow to the heart muscle.
4. Heart attack (myocardial infarction): This is a type of myocardial ischemia that occurs when the blood flow to the heart muscle is completely blocked, resulting in damage or death of the cardiac tissue.
Myocardial ischemia can be diagnosed through a variety of tests, including electrocardiograms (ECGs), stress tests, and imaging studies such as echocardiography or cardiac magnetic resonance imaging (MRI). Treatment options for myocardial ischemia include medications such as nitrates, beta blockers, and calcium channel blockers, as well as lifestyle changes such as quitting smoking, losing weight, and exercising regularly. In severe cases, surgical procedures such as coronary artery bypass grafting or angioplasty may be necessary.
