While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

Diving and the risk of barotrauma. (1/841)

STUDY OBJECTIVES: Pulmonary barotrauma (PBT) of ascent is a feared complication in compressed air diving. Although certain respiratory conditions are thought to increase the risk of suffering PBT and thus should preclude diving, in most cases of PBT, risk factors are described as not being present. The purpose of our study was to evaluate factors that possibly cause PBT. DESIGN: We analyzed 15 consecutive cases of PBT with respect to dive factors, clinical and radiologic features, and lung function. They were compared with 15 cases of decompression sickness without PBT, which appeared in the same period. RESULTS: Clinical features of PBT were arterial gas embolism (n = 13), mediastinal emphysema (n = 1), and pneumothorax (n = 1). CT of the chest (performed in 12 cases) revealed subpleural emphysematous blebs in 5 cases that were not detected in preinjury and postinjury chest radiographs. A comparison of predive lung function between groups showed significantly lower midexpiratory flow rates at 50% and 25% of vital capacity in PBT patients (p < 0.05 and p < 0.02, respectively). CONCLUSIONS: These results indicate that divers with preexisting small lung cysts and/or end-expiratory flow limitation may be at risk of PBT.  (+info)

Renal ischemia/reperfusion leads to macrophage-mediated increase in pulmonary vascular permeability. (2/841)

BACKGROUND: Despite the advent of dialysis, survival with acute renal failure when associated with multiorgan failure is poor. The development of lung injury after shock or visceral ischemia has been shown; however, the effects of isolated renal ischemia/reperfusion injury (IRI) on the lungs are unclear. We hypothesized that isolated renal IRI could alter pulmonary vascular permeability (PVP) and that macrophages could be important mediators in this response. METHODS: Rats (N = 5 per group) underwent renal ischemia for 30 minutes, followed by reperfusion. Lung vascular permeability was evaluated by quantitation of Evans blue dye extravasation from vascular space to lung parenchyma at 1, 24, 48, or 96 hours after reperfusion. Serum was collected for blood urea nitrogen and creatinine at each time point. To examine the role of the macrophage, the macrophage pacifant CNI-1493, which inhibits the release of macrophage-derived inflammatory products, was administered in a blinded fashion during renal IRI. RESULTS: PVP was significantly (P < 0.05) increased at 24 hours and peaked at 48 hours after IRI compared with shams as well as baseline levels. PVP after IRI became similar to shams after 96 hours. This correlated with increases in blood urea nitrogen and creatinine at similar time points. At 48 hours, CNI-1493 significantly abrogated the increase in PVP compared with IRI alone. However, CNI-1493 did not alter the course of the acute renal failure. Pulmonary histology demonstrated interstitial edema, alveolar hemorrhage, and red blood cell sludging after renal IRI, which was partially attenuated by CNI-1493. CONCLUSIONS: Increased PVP develops after isolated renal IRI, and macrophage-derived products are mediators in this response. These findings have implications for understanding the mechanisms underlying respiratory dysfunction associated with acute renal failure.  (+info)

Isoproterenol improves ability of lung to clear edema in rats exposed to hyperoxia. (3/841)

Exposure of adult rats to 100% O(2) results in lung injury and decreases active sodium transport and lung edema clearance. It has been reported that beta-adrenergic agonists increase lung edema clearance in normal rat lungs by upregulating alveolar epithelial Na(+)-K(+)-ATPase function. This study was designed to examine whether isoproterenol (Iso) affects lung edema clearance in rats exposed to 100% O(2) for 64 h. Active Na(+) transport and lung edema clearance decreased by approximately 44% in rats exposed to acute hyperoxia. Iso (10(-6) M) increased the ability of the lung to clear edema in room-air-breathing rats (from 0.50 +/- 0.02 to 0.99 +/- 0. 05 ml/h) and in rats exposed to 100% O(2) (from 0.28 +/- 0.03 to 0. 86 +/- 0.09 ml/h; P < 0.001). Disruption of intracellular microtubular transport of ion-transporting proteins by colchicine (0. 25 mg/100 g body wt) inhibited the stimulatory effects of Iso in hyperoxia-injured rat lungs, whereas the isomer beta-lumicolchicine, which does not affect microtubular transport, did not inhibit active Na(+) transport stimulated by Iso. Accordingly, Iso restored the lung's ability to clear edema after hyperoxic lung injury, probably by stimulation of the recruitment of ion-transporting proteins (Na(+)-K(+)-ATPase) from intracellular pools to the plasma membrane in rat alveolar epithelium.  (+info)

Inhaled NO preadministration modulates local and remote ischemia-reperfusion organ injury in a rat model. (4/841)

Inhaled nitric oxide (iNO) has been shown to have a protective effect in lung ischemia-reperfusion (I/R)-induced injuries. We studied the role of iNO (10 parts/million for 4 h) administered before I/R. In an isolated perfused lung preparation, iNO decreased the extravascular albumin accumulation from 2,059 +/- 522 to 615 +/- 105 microl and prevented the increase in lung wet-to-dry weight ratio. To study the mechanisms of this prevention, we evaluated the role of nitric oxide (NO) transport and lung exposure with matched experiments by using either lungs or blood of animals exposed to iNO and blood or lungs of naive animals. iNO-exposed blood with naive lungs did not limit the extravascular albumin accumulation (2,561 +/- 397 microl), but iNO-exposed lungs showed a leak not significantly different from the group in which both lungs and blood were iNO exposed (855 +/- 224 vs. 615 +/- 105 microl). An improvement in heart I/R left ventricular developed pressure in the animals exposed to iNO showed that blood-transported NO was, however, sufficient to trigger remote organ endothelium and reduce the consequences of a delayed injury. In conclusion, preventive iNO reduces the consequences of lung I/R injuries by a mechanism based on tissue or endothelium triggering.  (+info)

ICAM-1 and CD11b inhibition worsen outcome in rats with E. coli pneumonia. (5/841)

We investigated whether inhibiting an endothelial adhesion molecule [intracellular adhesion molecule 1 (ICAM-1)] would alter outcome and lung injury in a similar fashion to inhibition of a leukocyte adhesion molecule (integrin CD11b) in a rat model of gram-negative pneumonia. Inhibition of ICAM-1 with monoclonal antibody (MAb) 1A29 (1 mg/kg sc or 0.2 or 2 mg/kg iv, q 12 h x 3) or of CD11b with MAb 1B6 (1 mg/kg sc, q 12 h x 3) were compared against similarly administered placebo proteins in rats challenged with intrabronchial Escherichia coli. After challenge, all animals were treated with antibiotics. ICAM-1 MAb (6 mg/kg, iv, total dose) increased mortality vs. control (P = 0.03). CD11b MAb (3 mg/kg, sc, total dose) did not significantly (P = 0.16) increase mortality rates, but this was not in a range of probability to exclude a harmful effect. All other doses of MAb had no significant effect on survival rates. ICAM-1 and CD11b MAbs had significantly different effects on the time course of lung injury, circulating white cells and lymphocytes, and lung lavage white cells and neutrophils (P = 0.04-0.003). CD11b MAb decreased, whereas ICAM-1 MAb increased these measures compared with control from 6 to 12 h after E. coli. However, from 144 to 168 h after E. coli both MAbs increased these measures compared with control rats but to a greater level with CD11b MAb. Thus both ICAM-1 and CD11b appear to be necessary for survival during E. coli pneumonia. Although these adhesion molecules may participate differently in early lung injury, with CD11b increasing and ICAM-1 decreasing inflammation and injury, both are important for the resolution of later injury. During gram-negative pneumonia the protective roles of ICAM-1 and CD11b may make their therapeutic inhibition difficult.  (+info)

Intratracheal anti-tumor necrosis factor-alpha antibody attenuates ventilator-induced lung injury in rabbits. (6/841)

To evaluate the role of tumor necrosis factor (TNF)-alpha in the pathogenesis of ventilator-induced lung injury, we 1) measured TNF-alpha production in the lung caused by conventional mechanical ventilation (CMV) and 2) evaluated the protective effect of anti-TNF-alpha antibody (Ab) in saline-lavaged rabbit lungs. After they received saline lung lavage, rabbits were intratracheally instilled with 1 mg/kg of polyclonal anti-TNF-alpha Ab in the high-dose group (n = 6), 0.2 mg/kg of anti-TNF-alpha Ab in the low-dose group (n = 6), serum IgG fraction in the Ab control group (n = 6), and saline in the saline control group (n = 7). Animals then underwent CMV for 4 h. Levels of TNF-alpha in lung lavage fluid were significantly higher after CMV than before in both control groups. Pretreatment with intratracheal instillation of high and low doses of anti-TNF-alpha Ab improved oxygenation and respiratory compliance, reduced the infiltration of leukocytes, and ameliorated pathological findings. CMV led to TNF-alpha production in the lungs, and intratracheal instillation of anti-TNF-alpha Ab attenuated CMV-induced lung injury in this model.  (+info)

Pressure is proinflammatory in lung venular capillaries. (7/841)

Endothelial responses may contribute importantly to the pathology of high vascular pressure. In lung venular capillaries, we determined endothelial [Ca(2+)](i) by the fura-2 ratioing method and fusion pore formation by quantifying the fluorescence of FM1-43. Pressure elevation increased endothelial [Ca(2+)](i). Concomitantly evoked exocytotic events were evident in a novel spatial-temporal pattern of fusion pore formation. Fusion pores formed predominantly at vascular branch points and colocalized with the expression of P-selectin. Blockade of mechanogated Ca(2+) channels inhibited these responses, identifying entry of external Ca(2+) as the critical triggering mechanism. These endothelial responses point to a proinflammatory effect of high vascular pressure that may be relevant in the pathogenesis of pressure-induced lung disease.  (+info)

Pulmonary and bronchial circulatory responses to segmental lung injury. (8/841)

In regional lung injury, pulmonary blood flow decreases to the injured regions, and anastomotic bronchial blood flow and total bronchial blood flow increase. However, the pattern of redistribution of the two blood flows to the injured and noninjured areas is not known. In six anesthetized sheep, pulmonary and bronchial blood flows were measured with 15-microm fluorescent microspheres by using the reference flow method. Blood flows were measured in the control state and 1 h after instilling 1 ml/kg of 0. 1 N hydrochloric acid into a dependent segment of the left lung. The lungs were then removed, dried, and cubed into approximately 2-cm cubes while spatial coordinates were noted. Blood flow to each piece was calculated. Mean pulmonary blood flow to the noninjured pieces went from 730 +/- 246 to 574 +/- 347 ml/min (P = 0.22), whereas in the injured pieces the pulmonary blood flow decreased from 246 +/- 143 to 56 +/- 46 ml/min (P < 0.01). In contrast, bronchial blood flow to the injured pieces increased from 0.51 +/- 0.1 to 1.43 +/- 0. 85 ml/min (P = 0.005). We measured the change in flow as it related to the distance from the center of the injured area. Pulmonary blood flow decreased most at the center of the injury, whereas bronchial blood flow doubled at the center of injury and decreased with the distance away from the injury. The absolute increase in bronchial blood flow was substantially less than the decrease in pulmonary blood flow in the injured pieces. We also partitioned the observed variation in pulmonary and bronchial blood flow into that attributable to structure and that due to lung injury and found that 48% of the variation in pulmonary blood flow could be attributed to structure, whereas in the bronchial circulation 70% was attributable to structure. The reasons for these differences are not known and may reflect the intrinsic properties of the systemic and pulmonary circulations.  (+info)

FIGURE 9. FRH-augmented cell death is not mediated by a soluble factor. A, The media of MLE-15 cells exposed to TNF-a and various incubation temperatures for 18 h was collected and transferred to MLE-15 cells and then incubated at 37˚C for 18 h. No difference in the cell survival at each conditioning dose of TNF-a exists, although a trend for increased mortality from the cell-conditioned media of cells at 34˚C exists. This reflects increased production (B) of and increased stability (C) of the TNF-a at 34˚C compared with 39.5˚C. - Epithelial Apoptosis a Mechanism of Enhanced Alveolar Lipopolysaccharide-Induced Lung Injury by Febrile-Range Hyperthermia Augments
PHILADELPHIA, March 11, 2013 /3BL Media/ - Once the initial episode of influenza has passed, the chronic effects tend to be overlooked. The results of a new study indicate that the cytokine interleukin-22 (IL-22) plays a critical role in normal lung repair following influenza infection. This study is published in the April 2013 issue of The American Journal of Pathology.. With the increasing prevalence of more infective and/or virulent strains of influenza, understanding the impact of virus on the host epithelium and the processes involved in lung repair are of great importance, says John F. Alcorn, PhD, an immunologist affiliated with the department of pediatrics at the Childrens Hospital of Pittsburgh of UPMC. He notes that the findings open up new possibilities for developing therapeutic agents that promote recovery of normal lung function and architecture after influenza infection and lessen the likelihood of secondary infections. A key finding is that even after the resolution of ...
Unlike Hills criteria, the US Surgeon General Expert Committee suggested to consider alternative explanations as a causality criteria. First of all, the possibility of fungi as a cause of lung injury. Although there were no other significant risk factors than HDs in the studies of lung injury, the first epidemiological study showed significant association between fungi at room reported by questionnaire administration with lung injury, even after adjustment for various variables [12]. Association with fungi was substantially small compared to association with the HDs; in addition, there was no consistency of results, as there was no significance in the analysis of different control groups. Furthermore, fungi were not detected in the patients specimen. Above all, there was no significant association between fungi and lung injury among the study in children and community-based case control study [12,13]. Thus, the possibility that fungi may be a direct cause of lung injury is very low, and it is ...
While legal challenges form just one half of the effort to curb vaping-related injuries, medical providers are striving to better characterize and treat these illnesses. Such research is hampered by the unknown root cause of lung injury. Initial onset of vaping-related lung injuries can be hard to identify, with symptoms including fever, abdominal pain, and diarrhea. Later onset of respiratory injuries is also expected in the form of these vaping-associated lung injuries, which may include coughing, nausea, watery diarrhea, and chest or abdominal pain. Yet, over 1,000 cases of vaping associated-lung injury have been reported without a specified cause since June 2019. In response to this ongoing outbreak, the Utah Department of Health conducted a case study to describe the correlation between vape use and associated lung injuries. They found that individuals who used e-cigarettes with THC cartridges, the active ingredient in marijuana, experienced disproportionately greater hospitalization and ...

Cases of lung injuries in Stamford and Connecticut are similar to reports around the country involving e-cigarettes containing THC exclusively, a combination of nicotine and THC, or just nicotine, that have caused similar symptoms. However, the CDC found that the vast majority of lung injuries due to vaping come from cartridges that contain THC, which is the principal psychoactive component of cannabis.. ...
Currently, ALI and ARDS therapy focuses on the lungs to maintain gas exchange and minimize further injury. These researchers examined rats with lung injury and determined that the brain regions that control breathing are affected also. In fact, the characteristics of the pathologic breathing pattern remain even when the lungs are removed. In addition, inflammation was evident in the part of the brain that generates the breathing pattern. This indicates that the lungs are not the only factor involved in breathing disorders in lung injury ...

A pulmonary contusion, also known as lung contusion, is a bruise of the lung, caused by chest trauma. As a result of damage to capillaries, blood and other fluids accumulate in the lung tissue. The excess fluid interferes with gas exchange, potentially leading to inadequate oxygen levels (hypoxia). Unlike pulmonary laceration, another type of lung injury, pulmonary contusion does not involve a cut or tear of the lung tissue. A pulmonary contusion is usually caused directly by blunt trauma but can also result from explosion injuries or a shock wave associated with penetrating trauma. With the use of explosives during World Wars I and II, pulmonary contusion resulting from blasts gained recognition. In the 1960s its occurrence in civilians began to receive wider recognition, in which cases it is usually caused by traffic accidents. The use of seat belts and airbags reduces the risk to vehicle occupants. Diagnosis is made by studying the cause of the injury, physical examination and chest ...

N2 - The effects of phorbol myristate acetate (PMA) induced lung injury on the pulmonary and systemic blood flow contributions to the trachea and main bronchi (upper airways) were assessed in anesthetized dogs by injecting 15 μm radiolabeled microspheres into the right and left heart, respectively. Upper airway blood flow was studied in lungs given the following treatments: (1) PMA; (2) PMA in lungs pretreated with the thromboxane synthetase inhibitor OKY-046, and (3) PMA in lungs pretreated with the antioxidant catalase. After microsphere injections, the tracheal cartilage, tracheal muscle-mucosa, and main bronchi were excised. The results of this study indicate that under normal conditions, tracheal mucosa [33-52 ml·min-·(100 g)-1] and tracheal cartilage [18-27 ml·min-1·(100 g)-1] blood flow is primarily ...
Inflammation is involved in the pathogenesis of seawater aspiration-induced acute lung injury (ALI). Although several studies have shown that Semaphorin 7A (SEMA7A) promotes inflammation, there are limited reports regarding immunological function of SEMA7A in seawater aspiration-induced ALI. Therefore, we investigated the role of SEMA7A during seawater aspiration-induced ALI. Male Sprague-Dawley rats were underwent seawater instillation. Then, lung samples were collected at an indicated time for analysis. In addition, rat pulmonary microvascular endothelial cells (RPMVECs) were cultured and then stimulated with 25% seawater for indicated time point. After these treatments, cells samples were collected for analysis. In vivo, seawater instillation induced lung histopathologic changes, pro-inflammation cytokines release and increased expression of SEMA7A. In vitro, seawater stimulation led to pro-inflammation cytokine release, cytoskeleton remodeling and increased monolayer permeability in pulmonary

Comment on Assessment of Aspiration-Induced lung Injuries among Acute Drug Poisoning Patients; Loghman Hakim Hospital, Poisoning center
Acute lung injury complicates approximately 25-30% of subjects undergoing oesophagectomy. Experimental studies suggest that treatment with beta agonists may prevent the development of acute lung injury by decreasing inflammatory cell infiltration, activation and inflammatory cytokine release, enhancing basal alveolar fluid clearance and improving alveolar capillary barrier function.The Beta Agonist Lung Injury TrIal (prevention) is a multi-centre, randomised, double blind, placebo-controlled trial. The aim of the trial is to determine in patients undergoing elective transthoracic oesphagectomy, if treatment with inhaled salmeterol 100 mcg twice daily started at induction of anaesthesia and continued for 72 hours thereafter compared to placebo affect the incidence of early acute lung injury and other clinical, resource and patient focused outcomes. The primary outcome will be the development of acute lung injury within 72 hours of oesophagectomy. The trial secondary outcomes are the development of acute

BACKGROUND: Platelet-activating factor is a mediator of lung injury during cardiac operation. Platelet-activating factor antagonists reduce lung injury in animal models of cardiopulmonary bypass but there is no confirmatory evidence in clinical practice. METHODS: The effect of a low or high dose of a platelet-activating factor antagonist (Lexipafant) was assessed in a single center, double-blind, placebo-controlled, parallel group study. One hundred fifty patients undergoing coronary artery bypass grafting were randomized by minimization into three groups to receive placebo infusion, 10 or 100 mg of lexipafant for over 24 hours. Serial arterial oxygen and carbon dioxide tension, alveolar arterial oxygen gradient, and percent saturation were measured before operation and at 1, 6, 24, 48 hours, and 5 days after operation. RESULTS: Patient groups were similar with respect to age, sex, body surface area, and urgency of operation. Likewise, the groups were similar with respect to duration of cardiopulmonary
Ventilator-induced lung injury (VILI) contributes to mortality in ARDS. Particularly preinjured lungs are susceptible to VILI despite protective ventilation. We previously observed protection against VILI by Adrenomedullin (AM). Here we analyzed impact VILI on lung injury, pulmonary and systemic inflammation, bacterial burden and end-organ injury in established pneumonia. Further AM therapy was investigated.. 24h after infection with S. pneumoniae mice were subjected to MV (12ml/kg, 6h) and AM treatment. Lung permeability, oxygenation, lung mechanics, lung and plasma cytokines and leukocytes, bacterial burden in lung, blood spleen, ALT, AST, creatinine and urine output were assessed. Expression of AM and its receptor complex (CRLR; RAMP1-3) were studied. In pneumonia MV aggravated lung injury indicated by increased pulmonary permeability, oxygenation failure and worsening of lung mechanics. MV dramatically increased lung and blood cytokine levels in pneumonia, while lung leukocyte counts in ...

With the increasing prevalence of more infective and/or virulent strains of influenza, understanding the impact of virus on the host epithelium and the processes involved in lung repair are of great importance, says John F. Alcorn, PhD, an immunologist affiliated with the department of pediatrics at the Childrens Hospital of Pittsburgh of UPMC. He notes that the findings open up new possibilities for developing therapeutic agents that promote recovery of normal lung function and architecture after influenza infection and lessen the likelihood of secondary infections. A key finding is that even after the resolution of infection, influenza results in lung parenchymal remodeling that may be critical to susceptibility to further injury, says Dr. Alcorn. This series of experiments used 6- to 8-week-old wild-type (WT) mice (C57BL/6 strain) as well as IL-22-deficient mice, infected with influenza A PR/8/34 H1N1 or control vehicle. To determine the distribution of IL-22 in the lung, they used ...
Expression analysis, microscopy, chromatin immunoprecipitation, electrophoretic mobility shift assays, and VE-cadherin-luciferase reporter experiments demonstrated that KLF4 interacted with specific domains of VE-cadherin promoter and regulated the expression of VE-cadherin at AJs. KLF4 knockdown disrupted the endothelial barrier, indicating that KLF4 is required for normal barrier function. In vivo studies in mice showed augmented lipopolysaccharide-induced lung injury and pulmonary edema following Klf4 depletion.. ...

Invading pathogens may trigger overactivation of the innate immune system, which results in the release of large amounts of proinflammatory cytokines (cytokine storm) and leads to the development of pulmonary edema, multiorgan failure, and shock. PIAS1 is a multifunctional and potent anti-inflammatory protein that negatively regulates several key inflammatory pathways such as Janus kinase (JAK)-signal transducer and activator of transcription (STAT) and nuclear factor κB (NF-κB). We discovered a ubiquitin E3 ligase, HECTD2, which ubiquitinated and mediated the degradation of PIAS1, thus increasing inflammation in an experimental pneumonia model. We found that GSK3β phosphorylation of PIAS1 provided a phosphodegron for HECTD2 targeting. We also identified a mislocalized HECTD2 polymorphism, HECTD2A19P, that was present in 8.5% of the population and functioned to reduce inflammation. This polymorphism prevented HECTD2/PIAS1 nuclear interaction, thus preventing PIAS1 degradation. The HECTD2A19P ...
BACKGROUND: Major burns can alter the pharmacokinetics of opiate analgesics, which are commonly used perioperatively. Fentanyl undergoes a significant amount of pulmonary pharmacokinetic transition. This study was conducted to compare the pharmacokinetics of fentanyl in major burns, with and without lung injury, during the subacute hyperdynamic phase of recovery. METHODS: Twelve adults, with total body surface area (TBSA) 51.0 +/- 11.8% burns, aged 34.9 +/- 9.6 years, with a lung injury related to the burn, were studied at 15.4 +/- 9.4 days after the injury. Another 8 patients, aged 39.8 +/- 10.5 years, with TBSA 46.3 +/- 19.4%, at 19.3 +/- 10.9 days, without lung injury, served as controls. Fentanyl 200microgram was given intravenously over 10 seconds. Blood samples (n = 20) were collected at predetermined intervals. A two-compartment model was used for pharmacokinetic analyses of the fentanyl concentrations, as determined by LC/MS. The cardiac index (CI) was also measured using an esophageal ...
Acute lung injury (ALI) is an example of a critical care syndrome with limited treatment options once the condition is fully established.Not surprisingly, many treatments targeting the mechanisms identified in preclinical studies have failed to improve patient outcomes.The most likely reason could be due to inadequate and delayed recognition of patients at risk and the subsequent development of the full blown syndrome.ALI/ARDS usually develops during the first hours of ICU admission, and often is the very reason for ICU admission.. Clinical prediction models have been extensively used in the clinical practice to identify patients at high risks who may benefit from specific interventions. However, no such tool exists to predict the development of ALI in patients at risk. We have recently developed an ALI prediction model (Lung Injury Prediction Score:LIPS)which incorporates demographic, environmental and clinical characteristics at the time of, and before, hospital admission. If validated, this ...
The purpose of the study is to identify the patients at high risk of developing Acute Lung Injury (ALI) at the time of hospital admission, and before intensive care unit admission.. Aim 1- To validate the prediction model (Lung Injury Prediction Score) in a population based sample of hospitalized patients.. Aim 2- To determine the significance of health-care related ALI risk modifiers in a population based sample.. Aim 3- To compare the short and long term outcomes between patients at high risk who do, and do not develop ALI.. ...

Chief Investigator:. Miss Elena Cavallaro. Funding Amount:. $34,874. Recipient:. Flinders University. Overview:. Bronchiolitis and pneumonia are leading causes of infant hospitalisation in Australia. The exaggerated immunological insult stemming from these infections on developing lungs is associated with early-childhood asthma development. We have used a small protein, feG, to reduce the consequences of acute lung injury in various adult animal models, by dampening the immune response. We aim to assess feG efficacy in reducing the short and long-term effects of bronchiolitis and pneumonia during infancy, where feG may be an ideal candidate for returning the balance of the immune response in the airways.. ...
With modern therapy many patients are surviving an initial episode of acute lung injury (ALI). A patient surviving ALI may have a recurrent episode, which oftens has a high mortality rate. Therefore it is important to identify and correct any possible contributory factors.
Aim: This study was to observe the changes of the gene expression of microRNA-155 and 127 in the neonatal rats with Acute Lung Injury (ALI). Methods:..

Figure 3: The anti-inflammatory mechanism of omentin. Omentin activates AMPK, which further blocks E-selection and reduces endothelial inflammation. AMPK also activates eNOS, which has vasodilation effect and blocks JNK signaling. JNK activates inflammation through TNFα mediated COX2 effect. Moreover, omentin inhibits NF-κB signaling pathway and thus inhibits inflammation. Under obese state, the production of omentin is lower which is associated with worse proinflammation and possible lung injury ...
