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.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Site of myocardial infarction. A determinant of the cardiovascular changes induced in the cat by coronary occlusion. (1/2428)

The influence of site of acute myocardial infarction on heart rate, blood pressure, cardiac output, total peripheral resistance (TPR), cardiac rhythm, and mortality was determined in 58 anesthetized cats by occlusion of either the left anterior descending (LAD), left circumflex or right coronary artery. LAD occlusion resulted in immediate decrease in cardiac output, heart rate, and blood pressure, an increase in TPR, and cardiac rhythm changes including premature ventricular beats, ventricular tachycardia, and occasionally ventricular fibrillation. The decrease in cardiac output and increase in TPR persisted in the cats surviving a ventricular arrhythmia. In contrast, right coronary occlusion resulted in a considerably smaller decrease in cardiac output. TPR did not increase, atrioventricular condition disturbances were common, and sinus bradycardia and hypotension persisted in the cats recovering from an arrhythmia. Left circumflex ligation resulted in cardiovascular changes intermediate between those produced by occlusion of the LAD or the right coronary artery. Mortality was similar in each of the three groups. We studied the coronary artery anatomy in 12 cats. In 10, the blood supply to the sinus node was from the right coronary artery and in 2, from the left circumflex coronary artery. The atrioventricular node artery arose from the right in 9 cats, and from the left circumflex in 3. The right coronary artery was dominant in 9 cats and the left in 3. In conclusion, the site of experimental coronary occlusion in cats is a major determinant of the hemodynamic and cardiac rhythm changes occurring after acute myocardial infarction. The cardiovascular responses evoked by ligation are related in part to the anatomical distribution of the occluded artery.  (+info)

Control of ketogenesis from amino acids. IV. Tissue specificity in oxidation of leucine, tyrosine, and lysine. (2/2428)

In vitro and in vivo studies were made on the tissue specificity of oxidation of the ketogenic amino acids, leucine, tyrosine, and lysine. In in vitro studies the abilities of slices of various tissues of rats to form 14CO2 from 14C-amino acids were examined. With liver, but not kidney slices, addition of alpha-ketoglutarate was required for the maximum activities with these amino acids. Among the various tissues tested, kidney had the highest activity for lysine oxidation, followed by liver; other tissues showed very low activity. Kidney also had the highest activity for leucine oxidation, followed by diaphragm; liver and adipose tissue had lower activities. Liver had the highest activity for tyrosine oxidation, but kidney also showed considerable activity; other tissues had negligible activity. In in vivo studies the blood flow through the liver or kidney was stopped by ligation of the blood vessels. Then labeled amino acids were injected and recovery of radioactivity in respiratory 14CO2 was measured. In contrast to results with slices, no difference was found in the respiratory 14CO2 when the renal blood vessels were or were not ligated. On the contrary ligation of the hepatic vessels suppressed the oxidations of lysine and tyrosine completely and that of leucine partially. Thus in vivo, lysine and tyrosine seem to be metabolized mainly in the liver, whereas leucine is metabolized mostly in extrahepatic tissues and partly in liver. Use of tissue slices seems to be of only limited value in elucidating the metabolisms of these amino acids.  (+info)

Effects of chronic nitric oxide activation or inhibition on early hepatic fibrosis in rats with bile duct ligation. (4/2428)

Hepatic fibrosis or increased liver collagen contents drive functional abnormalities that, when extensive, may be life threatening. The purpose of this study was to assess the effects of the chronic stimulation or inhibition of nitric oxide synthesis in rats with hepatic fibrosis induced by permanent common bile duct ligation (3 weeks) and the role of expression of the different nitric oxide synthase isoforms. Bile duct ligation led to an important accumulation of collagen in the hepatic parenchyma, as shown both histologically and by the hydroxyproline contents of livers. Bilirubin and serum enzyme activities (measured as markers of cholestasis) increased several-fold after bile duct ligation. The area of fibrotic tissue, liver hydroxyproline content and serum markers of cholestasis were clearly related in obstructed rats. The absence of modifications in haemodynamic parameters excludes circulatory changes from being responsible for the development of liver alterations. In animals treated with NG-nitro-L-arginine methyl ester (L-NAME) the area of fibrosis was similar to that of untreated animals, the signs of cholestasis and cellular injury being more evident. In rats treated with L-arginine the area of fibrosis was almost three times larger than that found in bile duct ligated rats and in L-NAME-treated bile duct ligated rats, although the observed biochemical changes were similar to those seen in rats treated with L-NAME. Our results with inducible nitric oxide synthase, obtained by Western blots and immunohistochemistry, indicate a greater expression of the inducible enzyme in bile duct ligated and L-arginine-treated animals and a lower expression in the L-NAME and control groups. Constitutive nitric oxide synthase expression, obtained by Western blots, was very similar in all groups, except for the L-arginine-treated rats in which it was lower. These results suggest that nitric oxide production may be a key factor in the development of fibrosis in bile duct ligated rats. They also support the hypothesis of a dual role for nitric oxide; one beneficial, mediated by its circulatory effects, and the second negative, through its local toxic effects.  (+info)

Uninjured C-fiber nociceptors develop spontaneous activity and alpha-adrenergic sensitivity following L6 spinal nerve ligation in monkey. (5/2428)

We investigated whether uninjured cutaneous C-fiber nociceptors in primates develop abnormal responses after partial denervation of the skin. Partial denervation was induced by tightly ligating spinal nerve L6 that innervates the dorsum of the foot. Using an in vitro skin-nerve preparation, we recorded from uninjured single afferent nerve fibers in the superficial peroneal nerve. Recordings were made from 32 C-fiber nociceptors 2-3 wk after ligation and from 29 C-fiber nociceptors in control animals. Phenylephrine, a selective alpha1-adrenergic agonist, and UK14304 (UK), a selective alpha2-adrenergic agonist, were applied to the receptive field for 5 min in increasing concentrations from 0.1 to 100 microM. Nociceptors from in vitro control experiments were not significantly different from nociceptors recorded by us previously in in vivo experiments. In comparison to in vitro control animals, the afferents found in lesioned animals had 1) a significantly higher incidence of spontaneous activity, 2) a significantly higher incidence of response to phenylephrine, and 3) a higher incidence of response to UK. In lesioned animals, the peak response to phenylephrine was significantly greater than to UK, and the mechanical threshold of phenylephrine-sensitive afferents was significantly lower than for phenylephrine-insensitive afferents. Staining with protein gene product 9.5 revealed an approximately 55% reduction in the number of unmyelinated terminals in the epidermis of the lesioned limb compared with the contralateral limb. Thus uninjured cutaneous C-fiber nociceptors that innervate skin partially denervated by ligation of a spinal nerve acquire two abnormal properties: spontaneous activity and alpha-adrenergic sensitivity. These abnormalities in nociceptor function may contribute to neuropathic pain.  (+info)

Hypothermic neuroprotection of peripheral nerve of rats from ischaemia-reperfusion injury. (6/2428)

Although there is much information on experimental ischaemic neuropathy, there are only scant data on neuroprotection. We evaluated the effectiveness of hypothermia in protecting peripheral nerve from ischaemia-reperfusion injury using the model of experimental nerve ischaemia. Forty-eight male Sprague-Dawley rats were divided into six groups. We used a ligation-reperfusion model of nerve ischaemia where each of the supplying arteries to the sciatic-tibial nerves of the right hind limb was ligated and the ligatures were released after a predetermined period of ischaemia. The right hind limbs of one group (24 rats) were made ischaemic for 5 h and those of the other group (24 rats) for 3 h. Each group was further divided into three and the limbs were maintained at 37 degrees C (36 degrees C for 5 h of ischaemia) in one, 32 degrees C in the second and 28 degrees C in the third of these groups for the final 2 h of the ischaemic period and an additional 2 h of the reperfusion period. A behavioural score was recorded and nerve electrophysiology of motor and sensory nerves was undertaken 1 week after surgical procedures. At that time, entire sciatic-tibial nerves were harvested and fixed in situ. Four portions of each nerve were examined: proximal sciatic nerve, distal sciatic nerve, mid-tibial nerve and distal tibial nerve. To determine the degree of fibre degeneration, each section was studied by light microscopy, and we estimated an oedema index and a fibre degeneration index. The groups treated at 36-37 degrees C underwent marked fibre degeneration, associated with a reduction in action potential and impairment in behavioural score. The groups treated at 28 degrees C (for both 3 and 5 h) showed significantly less (P < 0.01; ANOVA, Bonferoni post hoc test) reperfusion injury for all indices (behavioural score, electrophysiology and neuropathology), and the groups treated at 32 degrees C had scores intermediate between the groups treated at 36-37 degrees C and 28 degrees C. Our results showed that cooling the limbs dramatically protects the peripheral nerve from ischaemia-reperfusion injury.  (+info)

Mid-term results of endoscopic perforator vein interruption for chronic venous insufficiency: lessons learned from the North American subfascial endoscopic perforator surgery registry. The North American Study Group. (7/2428)

PURPOSE: The safety, feasibility, and early efficacy of subfascial endoscopic perforator surgery (SEPS) for the treatment of chronic venous insufficiency were established in a preliminary report. The long-term clinical outcome and the late complications after SEPS are as yet undetermined. METHODS: The North American Subfascial Endoscopic Perforator Surgery registry collected information on 148 SEPS procedures that were performed in 17 centers in the United States and Canada between August 1, 1993, and February 15, 1996. The data analysis in this study focused on mid-term outcome in 146 patients. RESULTS: One hundred forty-six patients (79 men and 67 women; mean age, 56 years; range, 27 to 87 years) underwent SEPS. One hundred and one patients (69%) had active ulcers (class 6), and 21 (14%) had healed ulcers (class 5). One hundred and three patients (71%) underwent concomitant venous procedures (stripping, 70; high ligation, 17; varicosity avulsion alone, 16). There were no deaths or pulmonary embolisms. One deep venous thrombosis occurred at 2 months. The follow-up periods averaged 24 months (range, 1 to 53 months). Cumulative ulcer healing at 1 year was 88% (median time to healing, 54 days). Concomitant ablation of superficial reflux and lack of deep venous obstruction predicted ulcer healing (P <.05). Clinical score improved from 8.93 to 3.98 at the last follow-up (P <. 0001). Cumulative ulcer recurrence at 1 year was 16% and at 2 years was 28% (standard error, < 10%). Post-thrombotic limbs had a higher 2-year cumulative recurrence rate (46%) than did those limbs with primary valvular incompetence (20%; P <.05). Twenty-eight of the 122 patients (23%) who had class 5 or class 6 ulcers before surgery had an active ulcer at the last follow-up examination. CONCLUSIONS: The interruption of perforators with ablation of superficial reflux is effective in decreasing the symptoms of chronic venous insufficiency and rapidly healing ulcers. Recurrence or new ulcer development, however, is still significant, particularly in post-thrombotic limbs. The reevaluation of the indications for SEPS is warranted because operations in patients without previous deep vein thrombosis are successful but operations in those patients with deep vein thrombosis are less successful. Operations on patients with deep vein occlusion have poor outcomes.  (+info)

Contribution of extracranial lymphatics and arachnoid villi to the clearance of a CSF tracer in the rat. (8/2428)

The objective of this study was to determine the relative roles of arachnoid villi and cervical lymphatics in the clearance of a cerebrospinal fluid (CSF) tracer in rats. 125I-labeled human serum albumin (125I-HSA; 100 micrograms) was injected into one lateral ventricle, and an Evans blue dye-rat protein complex was injected intravenously. Arterial blood was sampled for 3 h. Immediately after this, multiple cervical vessels were ligated in the same animals, and plasma recoveries were monitored for a further 3 h after the intracerebroventricular injection of 100 micrograms 131I-HSA. Tracer recovery in plasma at 3 h averaged (%injected dose) 0.697 +/- 0.042 before lymphatic ligation and dropped significantly to 0.357 +/- 0. 060 after ligation. Estimates of the rate constant associated with the transport of the CSF tracer to plasma were also significantly lower after obstruction of cervical lymphatics (from 0.584 +/- 0. 072/h to 0.217 +/- 0.056/h). No significant changes were observed in sham-operated animals. Assuming that the movement of the CSF tracer to plasma in lymph-ligated animals was a result of arachnoid villi clearance, we conclude that arachnoid villi and extracranial lymphatic pathways contributed equally to the clearance of the CSF tracer from the cranial vault.  (+info)

Results:. Rebleeding tended to be less frequent with ligation than with sclerotherapy: 10 of 38 (26%) compared with 17 of 39 (44%) (difference, 17% [95% CI, 4% to 38%]), but results in the two groups were comparable for blood transfusions, for length of hospital stay, and for risk of death. Comparison of Kaplan-Meier estimates of time to rebleeding and death showed no statistical differences between treatments. Complications were less common in the ligation group: fewer patients in the ligation group had esophageal strictures (0 of 38 compared with 13 of 39 [33%]; P , 0.001) and had complicated esophageal ulcers (1 of 38 [2.6%] compared with 6 of 39 [15%]; P = 0.11). In addition, fewer ligation treatments were required to achieve variceal eradication (4.1 0.3 compared with 6.2 0.4; P , 0.001). ...
Results: Thirty seven files were included in the analysis. Files were divided in two groups according to the surgical technique performed; group (A) included 20 patients received transduodenal suture ligation of the bleeder and periduodenal triple ligation of the gastroduodenal, right gastro-epiploic and superior pancreatico-duodenal arteries and group (B) included 17 patients received only transduodenal suture ligation of the bleeder. There was neither rebleeding nor mortality in group (A). In group (B), four patients developed rebleeding postoperatively. Bleeding was haemodynamically insignificant and stopped spontaneously in 1 patient, 1 patient exsanguinated and died before re-surgery and 2 patients had re-surgery; one survived after periduodenal arterial ligation and the other died postoperatively due to complications of gastrectomy ...

Most commonly, following ligation the circularised plasmid, now containing your insert DNA, is transformed into competent bacteria for further selection and analysis. In bacteria, transformation refers to a genetic change brought about by taking up and expressing DNA i.e. your plasmid construct, and competence refers to the state of being able to take up DNA; most bacteria are not naturally transformable, but are made permeable to the plasmid DNA by chemical or electrochemical means. Competent cells are extremely fragile and should be handled gently, specifically kept cold and not vortexed. The transformation procedure is efficient enough for most lab purposes, with efficiencies as high as 109 transformed cells per microgram of DNA, but it is important to realize that even with high efficiency cells only 1 DNA molecule in about 10,000 is successfully transformed ...

from Brad Barbazuk Goal is to generate PCR fragments that contain the ends of PAC inserts that can be sequenced. For inverse PCR we cut the PAC once in the vector (near outward primer site) and once at unknown site in insert (and many other places outside these sites, that dont matter). Following ligation to generate small circles, PCR is performed with outward facing primers at the end of the vector that will amplify a product that contains the end of the insert. To increase the odds of getting an amplifiable product, we use two different enzymes (used singly!!) per pac end - NlaIII and RsaI for the SP6 end, and NlaIII and HinPI (or HhaI) for the T7 end. Primers ...
Objective-Accumulating evidence suggests a role of semaphorins in vascular homeostasis. Here, we investigate the role of Sema7A (semaphorin 7A) in atherosclerosis and its underlying mechanism. Approach and Results-Using genetically engineered Sema7A -/- ApoE -/- mice, we showed that deletion of Sema7A attenuates atherosclerotic plaque formation primarily in the aorta of ApoE -/- mice on a high-fat diet. A higher level of Sema7A in the atheroprone lesser curvature suggests a correlation of Sema7A with disturbed flow. This notion is supported by elevated Sema7A expression in human umbilical venous endothelial cells either subjected to oscillatory shear stress or treated with the PKA (protein kinase A)/CREB (cAMP response element-binding protein) inhibitor H89 (N-[2-(p-bromocinnamylamino)ethyl]-5-isoquinolinesulfonamide·2HCl hydrate). Further studies using the partial carotid artery ligation model showed that disturbed flow in the left carotid artery of Sema7A +/+ ApoE -/- mice promoted the ...

The impact of feeding after endoscopic treatment of gastroesophageal varices has never been investigated. It is still unknown whether early feeding may increase early rebleeding in patients with acute esophageal variceal bleeding treated with EVL. It is customary for clinicians to institute fasting for 2 or 3 days after emergency EVL. This may be a safe approach to watch against early rebleeding. However, many patients would be fasting for a longer time and nutrition may be impaired, possibly resulting in aggravation of ascites. Thus, the investigators conduct a controlled study to evaluate whether early feeding have a bad impact on patients receiving emergency EVL or histoacryl injection for bleeding gastric varices ...
The data supplied here convey a correlation of PDA closure with ventricular size/OFC normalization (Figs. 2-4) and represent the first documentation of this temporal relationship in the literature. The results must be interpreted with caution and should not be viewed as proof of a link between hsPDA, cerebral hemodynamics, and ventricular outflow. Although hydrocephalus is a well-documented consequence of PIVH,3,23 our case suggests that the unstable hemodynamic environment due to left-to-right shunting may also impede CSF outflow and, in addition to an underlying degree of IVH, may contribute mechanistically to ventriculomegaly. This relationship may not have been previously identified due to the nationwide variation in PDA diagnosis and treatment strategy,5 or to the lack of a definition surrounding PDA hemodynamic significance.6. It has been previously shown that a systemic hemodynamic change can immediately follow hsPDA ligation. Bissonnette and Benson detected both acute decline in CVP and ...

Anybody can get hemorrhoids especially now that diets have been leaning towards foods that have low fiber material and a high content of processed ingredients. Lack of proper water intake and the design of current toilet bowls also make the chances of getting hemorrhoids bigger. The cause of hemorrhoids is an increased pressure within the hemorrhoidal veins but there are countless number of ways that this increased pressure occurs. These are the risk factors that general increase the chance of one possessing a hemorrhoid ...

Medical treatment of hemorrhoids includes treatment of any underlying constipation, taking warm baths and applying an over-the-counter cream or suppository that may contain hydrocortisone. If medical treatment fails there are a number of ways to reduce the size or eliminate internal hemorrhoids. Each method varies in its success rate, risks and recovery time. Your doctor will discuss these options with you. Rubber band ligation is the most common outpatient procedure for hemorrhoids in the United States. It involves placing rubber bands around the base of an internal hemorrhoid to cut off its blood supply. This causes the hemorrhoid to shrink, and in a few days both the hemorrhoid and the rubber band fall off during a bowel movement. Possible complications include pain, bleeding and infection. After band ligation, your doctor may prescribe medications, including pain medication and stool softeners, before sending you home. Contact your doctor immediately if you notice severe pain, fever or ...
1. The inhibiting action of urine on catalase depends to a great extent on its reaction. The urine of a nephritic has no greater inhibiting power than normal urine provided the reaction of urines tested is neutral. 2. The catalytic activity of a single rabbits blood is constant from day to day. 3. There is considerable variation in the catalytic action of the blood of different rabbits. 4. Following ligation of the ureters the catalytic activity of the blood gradually decreases; the tissues of an animal which has died as a result of ligation of the ureters show a decided decrease in catalytic activity, when compared with those of normal animals. 5. Following bilateral nephrectomy the same decline of the catalytic action of the blood is observed as after bilateral ligation of ureters. 6. Following unilateral nephrectomy the catalytic activity of the blood may temporarily fall and then rise above its previous level, or it may fall continuously. Wherever the continuous fall occurs the animal dies. ...

Myocardial infarction (MI) is a disease of major consequence in the modern world, causing permanent, irreversible damage to the heart. Survivors are at risk for developing further cardiovascular pathologies such as heart failure. Further study of MI injury is crucial to improve the understanding and treatment of the post-MI heart. The most commonly used model for MI in vivo is surgical ligation of the left anterior descending coronary artery (LAD). There are two predominant approaches: permanent ligation (PL), where the LAD is permanently occluded with a suture, or ischaemia-reperfusion (IR), where the LAD is temporarily occluded before removing the suture to restore blood flow and tissue reperfusion. PL results in the majority of the area at risk becoming infarcted, leading to significant apoptotic cell death and a large scar. Conversely, IR salvages some of the area at risk; thus, the scar is smaller and includes reperfusion injury, an additional, albeit smaller, second wave of necrotic damage. PL may

For the Rapid DNA Ligation Kit, we guarantee , 1 x 106 transformants per μg religated pUC18 vector (sticky end as well as blunt end), i.e., this means that only 2.96 pg of vector (1 molecule of pUC 18 = of 2,96 ag [attogram!]), have be to be religated to result in this yield in transformants. This rate of religation is easily achieved in 5 minutes with the Rapid DNA Ligation Kit.. Note: This also means that when ligation products are checked using an agarose gel, a substantial proportion of the vector DNA used will still show up „unligated“. Considering the above mentioned molecular weight of pUC 18 this is is easily visualized..

An endoscopic instrument for the application of ligature binders and a ligature are described. A base body and an actuation part of a handle part are longitudinally displaceable relative to each other against an elastic force within a fixed range. Connected to the actuation part is an actuation rod at whose distal end a first ratchet heat is secured. A shaft, firmly connected to the base body, carries a second ratchet head at its distal end. With the help of the ratchet heads, which are matched to the toothed end zone of a ligature binder, a ligature can be drawn together. A ligature whose end zone has already been inserted into the endoscopic instrument prior to the operation can be brought into a closed shape with the help of a constricted zone in its binding part and of a longitudinal slot in its headpiece.

In the past I have had two main problems with failed ligation reactions. The first appeared to involve a seasonal decrease in the quality of MilliQ water (associated with filters which were not changed often enough). This wouldnt appear to have affected you, as your phosphorylated vector was religated. The second problem I have encountered, involves over CIPing your vector. Cheaper preparations of phosphatase have traces of exonuclease activity, these will nibble the ends of DNA. The more common problem is the carry over of CIP into the ligation reaction. This effectively removes the phosphates from your insert, thus no ligation and no transformants. I routinely use no more than 1unit CIP/pmole DNA ends (routinely 0.2unit/pmoleDNA). I heat inactivate the CIP (65C/20mins) in the presence of 5mM EDTA, phenol extract and gel purify the linearised vector. This method maybe a bit over the top, but I have had no problems cloning when my vector is purified in this way. Alternatively, one can use ...
