Duane Retraction Syndrome
A syndrome characterized by marked limitation of abduction of the eye, variable limitation of adduction and retraction of the globe, and narrowing of the palpebral fissure on attempted adduction. The condition is caused by aberrant innervation of the lateral rectus by fibers of the OCULOMOTOR NERVE.
A new alkali-resistant hemoglobin alpha2J Oxford gammaF2 in a Sicilian baby girl with homozygous beta0 thalassemia. (1/541)
A 10-mo-old baby girl with homozygous beta0 thalassemia and alphaJOxford, presenting the clinical picture of homozygous beta thalassemia is described. Hemoglobin electrophoresis showed three bands: the first two with the mobilities of hemoglobin Hb A2 (1%) and Hb F (69%), respectively, the third migrating a little faster than Hb A (30%). About 30% of her alpha chains were J Oxford which, bound to her gamma chains, produced a new alkali-resistant hemoglobin, alpha2 J Oxford gamma F2, which has not been described previously. Hemoglobin synthesis in vitro showed the absence of beta chain synthesis and an alpha/non-alpha ratio of 2. The patient's father was heterozygous for both the Hb J Oxford and beta0 thalassemia genes, the mother a carrier of beta0 thalassemia; four other relatives were carriers of Hb J Oxford, and one was a carrier of beta thalassemia. (+info)Alkali-treated collagen retained the triple helical conformation and the ligand activity for the cell adhesion via alpha2beta1 integrin. (2/541)
Alkaline treatment is a good method for extracting collagen with high recovery even from an aged animal specimen. However, the properties of collagen treated under alkaline conditions have not been well established yet. By the treatment with a solution of 3% sodium hydroxide and 1.9% monomethylamine, the isoelectric point of type I collagen was lowered from 9.3 to 4.8 because of the conversions of Asn and Gln to Asp and Glu. With the acidification of the pI, the denaturation temperature of the collagen was decreased from 42 to 35 degrees C after 20 d treatment, but the collagen-specific triple helical conformation was maintained. Human keratinocytes and fibroblasts adhered to the alkali-treated collagen via the collagen receptor integrin alpha2beta1. This indicates that the alkali-treated collagen maintained its property as a biological adherent molecule. Unlike acid-soluble collagen, alkali-treated collagen lost the ability to form fibrils at neutral pH under physiological conditions. This ability was lost even after 4 h of alkaline treatment, when the denaturation temperature of the collagen did not change. On the other hand, the alkali-treated collagen formed a fibrous precipitate with a uniform diameter of 50-70 nm under acidic conditions at 30 degrees C. (+info)Meningitis caused by an alkali-producing pseudomonad. (3/541)
The clinical and microbiological features of a case of meningitis, due to an alkali-producing pseudomonad which closely resembles Pseudomonas pseudoalcaligenes, are described. A respiratory infection and a course of antibiotic therapy before admission to hospital may have been predisposing factors to opportunistic infection by this normally saprophytic organism. The problems of identifying alkali-producing pseudomonads are discussed. (+info)Replication of African swine fever virus DNA in infected cells. (4/541)
We have examined the ultrastructural localization of African swine fever virus DNA in thin-sections of infected cells by in situ hybridization and autoradiography. Virus-specific DNA sequences were found in the nucleus of infected Vero cells at early times in the synthesis of the viral DNA, forming dense foci localized in proximity to the nuclear membrane. At later times, the viral DNA was found exclusively in the cytoplasm. Electron microscopic autoradiography of African swine fever virus-infected macrophages showed that the nucleus is also a site of viral DNA replication at early times. These results provide further evidence of the existence of nuclear and cytoplasmic stages in the synthesis of African swine fever virus DNA. On the other hand, alkaline sucrose sedimentation analysis of the replicative intermediates synthesized in the nucleus and cytoplasm of infected macrophages showed that small DNA fragments ( approximately 6-12S) were synthesized in the nucleus at an early time, whereas at later times, larger fragments of approximately 37-49S were labeled in the cytoplasm. Pulse-chase experiments demonstrated that these fragments are precursors of the mature cross-linked viral DNA. The formation of dimeric concatemers, which are predominantly head-to-head linked, was observed by pulsed-field electrophoresis and restriction enzyme analysis at intermediate and late times in the replication of African swine fever virus DNA. Our findings suggest that the replication of African swine fever virus DNA proceeds by a de novo start mechanism with the synthesis of small DNA fragments, which are then converted into larger size molecules. Ligation or further elongation of these molecules would originate a two-unit concatemer with dimeric ends that could be resolved to generate the genomic DNA by site-specific nicking, rearrangement, and ligation as has been proposed in the de novo start model of Baroudy et al. (B. M. Baroudy, S. Venkatesam, and B. Moss, 1982, Cold Spring Harbor Symp. Quant. Biol. 47, 723-729) for the replication of vaccinia virus DNA. (+info)Isolation and characterization of proteoglycans from human follicular fluid. (5/541)
Two proteoglycans differing in size and composition were isolated from human follicular fluid. The larger one of high density had a molecular mass of 3.0x10(6) Da, as determined by laser light-scattering, and was substituted with 15-20 chondroitin sulphate (CS) chains (Mr 60000-65000). Half of the CS disaccharides were 6-sulphated, whereas the remaining ones were non-sulphated. Digestion of the CS proteoglycan with chondroitinase ABC lyase, followed by SDS/PAGE, yielded a protein core of 600 to 700 kDa including substituted oligosaccharides, and a band of 70 kDa that was identified as the heavy-chain component of the inter-alpha-trypsin inhibitor (ITI). Western blotting of the CS proteoglycan showed that this had reactivity with antibodies raised against human versican. Electron microscopy (EM) of the CS proteoglycan also revealed a versican-like structure, with one globular domain at each end of a long extended segment substituted with CS side chains, as well as a structure interpreted as being the heavy chain of ITI attached to CS chains. Laser light-scattering revealed that the smaller proteoglycan had a molecular mass of 1. 1x10(6) Da, and EM demonstrated that it had a globular-protein core structure. The core protein, which showed immunological reactivity with perlecan antibodies, was substituted with approximately seven heparan sulphate (HS) and CS chains of similar size (50-55 kDa), the CS disaccharides being mainly 6-sulphated (68%), with a small proportion being 4-sulphated. The protein core was shown to be heterogeneous, with bands occurring at 215, 330 and 400 kDa after enzymic degradation of the glycosaminoglycan chains followed by SDS/PAGE analysis. The demonstration of intact molecules and fragments obtained after stepwise degradations, as shown by gel chromatography, supported a 'composite' structure of this proteoglycan. (+info)Isolation and properties of Enterococcus hirae mutants defective in the potassium/proton antiport system. (6/541)
A K+/H+ antiporter regulates cytoplasmic pH in Enterococcus hirae growing at alkaline pH. Mutants defective in this antiport activity were alkaline pH sensitive. One mutant, Pop1, lacked both K+/methylamine exchange at pH 9.5 and concomitant acidification of cytoplasmic pH. Pop1 grew well at pHs below 8 but did not at pHs above 9, conditions under which cytoplasmic pH was not fully acidified. (+info)Interaction of collagen molecules from the aspect of fibril formation: acid-soluble, alkali-treated, and MMP1-digested fragments of type I collagen. (7/541)
Collagen type I extracted with acid or digested with pepsin forms fibrils under physiological conditions, but this ability is lost when the collagen is treated with alkaline solution or digested with matrix metalloproteinase 1 (MMP1). When acid-soluble collagen was incubated with alkali-treated collagen, the fibril formation of acid-soluble collagen was inhibited. At 37 degrees C, at which alkali-treated collagen is denatured, the lag time was prolonged but the growth rate of fibrils was not affected. At 30 degrees C, at which the triple helical conformation of alkali-treated collagen is retained, the lag time was prolonged and the growth rate reduced. Heat-denatured alkali-treated collagen and MMP1-digested fragments have no inhibitory effect on the fibril formation of acid-soluble collagen. This means that the triple helical conformation and the molecular length are important factors in the interaction of collagen molecules and that alkali-treated collagen acts as a competitive inhibitor for fibril formation of collagen. We found that alkali-treated collagen and MMP1-digested fragments form fibrils that lack the D periodic banding pattern and twisted morphology under acidic conditions at the appropriate ionic strength. We also calculated the relative strengths of hydrophobic and electrostatic interactions between collagen molecules. When the hydrophobic interaction between linear collagen molecules was considered, we found a pattern of periodic maximization of the interactive force including the D period. On the other hand, the electrostatic interaction did not show the periodic pattern, but the overall interaction score affected fibril formation. (+info)Analysis of the in vivo interaction between a basic repressor and an acidic activator. (8/541)
The artificial basic repressor SSB24 represses transcription of a reporter construct activated by GCN4. We show that the positively charged SSB24 and the negatively charged acidic activator GCN4 interact in vitro and in vivo. However, deleting the interaction domain from the GCN4 activator does not result in loss of repression by SSB24. Similarly, transcription activated by the holoenzyme component SRB2 is repressed, although SSB24 and SRB2 do not interact. Repression by SSB24 therefore does not depend on the observed protein-protein interaction between SSB24 and GCN4. (+info)Alkalies, also known as basic compounds or bases, are substances that have a pH greater than 7 and can accept hydrogen ions (protons), thereby neutralizing acids and increasing the pH of a solution.
Alkalies are a type of basic compound that has a pH level greater than 7. They are also known as bases and can neutralize acids. Alkalies can react with acids to form salts and water. Some common alkalies include sodium hydroxide (lye), potassium hydroxide, and calcium hydroxide. When in solution, alkalies can increase the pH level of a substance, making it more basic or alkaline. They are widely used in various industries for different purposes such as cleaning, manufacturing, and processing.
Hypercalcemia is a condition characterized by an excessively high concentration of calcium ions in the blood serum, frequently exceeding 10.5 mg/dL or 2.6 mmol/L, which can lead to various symptoms and complications if not promptly addressed.
Hypercalcemia is a medical condition characterized by an excess of calcium ( Ca2+ ) in the blood. While the normal range for serum calcium levels is typically between 8.5 to 10.2 mg/dL (milligrams per deciliter) or 2.14 to 2.55 mmol/L (millimoles per liter), hypercalcemia is generally defined as a serum calcium level greater than 10.5 mg/dL or 2.6 mmol/L.
Hypercalcemia can result from various underlying medical disorders, including primary hyperparathyroidism, malignancy (cancer), certain medications, granulomatous diseases, and excessive vitamin D intake or production. Symptoms of hypercalcemia may include fatigue, weakness, confusion, memory loss, depression, constipation, nausea, vomiting, increased thirst, frequent urination, bone pain, and kidney stones. Severe or prolonged hypercalcemia can lead to serious complications such as kidney failure, cardiac arrhythmias, and calcification of soft tissues. Treatment depends on the underlying cause and severity of the condition.
Calcium Carbonate is a widely available and commonly used dietary supplement with the medical definition being a chemical compound, primarily used as an antacid for temporary relief of heartburn, indigestion, and upset stomach, which consists of three constituent parts: calcium (Ca2+), carbonate (CO3 2-), and water (H2O) molecules, often represented by the chemical formula CaCO3.
Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks and in the shells of many marine animals. As a mineral, it is known as calcite or aragonite.
In the medical field, calcium carbonate is often used as a dietary supplement to prevent or treat calcium deficiency. It is also commonly used as an antacid to neutralize stomach acid and relieve symptoms of heartburn, acid reflux, and indigestion.
Calcium carbonate works by reacting with hydrochloric acid in the stomach to form water, carbon dioxide, and calcium chloride. This reaction helps to raise the pH level in the stomach and neutralize excess acid.
It is important to note that excessive use of calcium carbonate can lead to hypercalcemia, a condition characterized by high levels of calcium in the blood, which can cause symptoms such as nausea, vomiting, constipation, confusion, and muscle weakness. Therefore, it is recommended to consult with a healthcare provider before starting any new supplement regimen.
A syndrome is a set of symptoms that collectively indicate a specific disease, disorder, or condition, often representing a common pathway or pattern of underlying physiological processes and/or anatomical abnormalities.
A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.
For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.
It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.
Calcinosis is a medical condition characterized by the abnormal deposition of calcium phosphate crystals in soft tissues, leading to the formation of hard nodular or plaque-like deposits that can cause pain, inflammation, and impaired mobility.
Calcinosis is a medical condition characterized by the abnormal deposit of calcium salts in various tissues of the body, commonly under the skin or in the muscles and tendons. These calcium deposits can form hard lumps or nodules that can cause pain, inflammation, and restricted mobility. Calcinosis can occur as a complication of other medical conditions, such as autoimmune disorders, kidney disease, and hypercalcemia (high levels of calcium in the blood). In some cases, the cause of calcinosis may be unknown. Treatment for calcinosis depends on the underlying cause and may include medications to manage calcium levels, physical therapy, and surgical removal of large deposits.
Technetium Tc 99m Medronate is a radiopharmaceutical preparation used in nuclear medicine imaging, specifically for bone scintigraphy, to evaluate various bone disorders such as fractures, tumors, and infections by visualizing bone metabolism through the uptake of the technetium-99m isotope in hydroxyapatite crystals of bone tissue.
Technetium Tc 99m Medronate is a radiopharmaceutical agent used in nuclear medicine for bone scintigraphy. It is a technetium-labeled bisphosphonate compound, which accumulates in areas of increased bone turnover and metabolism. This makes it useful for detecting and evaluating various bone diseases and conditions, such as fractures, tumors, infections, and arthritis.
The "Tc 99m" refers to the radioisotope technetium-99m, which has a half-life of approximately 6 hours and emits gamma rays that can be detected by a gamma camera. The medronate component is a bisphosphonate molecule that binds to hydroxyapatite crystals in bone tissue, allowing the radiolabeled compound to accumulate in areas of active bone remodeling.
Overall, Technetium Tc 99m Medronate is an important tool in nuclear medicine for diagnosing and managing various musculoskeletal disorders.
Duane Retraction Syndrome is a congenital ocular motility disorder characterized by limited abduction, narrowing of the palpebral fissure, and retraction of the globe on adduction, often associated with variable upshoot or downshoot.
Duane Retraction Syndrome (DRS) is a congenital eye movement disorder, characterized by limited abduction (lateral movement away from the nose) of the affected eye, and on attempted adduction (movement towards the nose), the eye retracts into the orbit and the lid narrows. It is often accompanied by other eye alignment or vision anomalies. The exact cause is not known, but it is believed to be a result of abnormal development of the cranial nerves that control eye movement during fetal development. DRS is usually idiopathic, but it can also be associated with other congenital anomalies. It is typically diagnosed in early childhood and managed with a combination of observation, prism glasses, and/or surgery, depending on the severity and impact on vision.
'Lung diseases' is a broad term that encompasses various respiratory disorders affecting the lung tissues, airways, or blood vessels, including but not limited to asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, tuberculosis, lung cancer, cystic fibrosis, and interstitial lung diseases, which can impair lung function, cause difficulty breathing, and potentially lead to severe complications or death if not properly managed.
Lung diseases refer to a broad category of disorders that affect the lungs and other structures within the respiratory system. These diseases can impair lung function, leading to symptoms such as coughing, shortness of breath, chest pain, and wheezing. They can be categorized into several types based on the underlying cause and nature of the disease process. Some common examples include:
1. Obstructive lung diseases: These are characterized by narrowing or blockage of the airways, making it difficult to breathe out. Examples include chronic obstructive pulmonary disease (COPD), asthma, bronchiectasis, and cystic fibrosis.
2. Restrictive lung diseases: These involve stiffening or scarring of the lungs, which reduces their ability to expand and take in air. Examples include idiopathic pulmonary fibrosis, sarcoidosis, and asbestosis.
3. Infectious lung diseases: These are caused by bacteria, viruses, fungi, or parasites that infect the lungs. Examples include pneumonia, tuberculosis, and influenza.
4. Vascular lung diseases: These affect the blood vessels in the lungs, impairing oxygen exchange. Examples include pulmonary embolism, pulmonary hypertension, and chronic thromboembolic pulmonary hypertension (CTEPH).
5. Neoplastic lung diseases: These involve abnormal growth of cells within the lungs, leading to cancer. Examples include small cell lung cancer, non-small cell lung cancer, and mesothelioma.
6. Other lung diseases: These include interstitial lung diseases, pleural effusions, and rare disorders such as pulmonary alveolar proteinosis and lymphangioleiomyomatosis (LAM).
It is important to note that this list is not exhaustive, and there are many other conditions that can affect the lungs. Proper diagnosis and treatment of lung diseases require consultation with a healthcare professional, such as a pulmonologist or respiratory therapist.
