Chemoprevention of mammary, cervix and nervous system carcinogenesis in animals using cultured Panax ginseng drugs and preliminary clinical trials in patients with precancerous lesions of the esophagus and endometrium. The anticarcinogenic effects and mechanisms of the biotechnological drugs of Panax ginseng C.A. Meyer cultivated in Russia, bioginseng, panaxel and panaxel- 5, were studied. Bioginseng was produced from a tissue culture of ginseng root cultured on standard medium, whereas panaxel and panaxel-5 were produced from ginseng tissue root cultures using standard mediums enriched with 2-carboxyethylgermanium sesquioxide and 1-hydroxygermatran-monohydrate respectively.

A seizure reported by witnesses or suspected from clinical signs observed prior to death and compatible with the definition raises the problematic of the relationship with sudden death. INCIDENCE AND RISK FACTORS: Sudden death is estimated to occur in 1 out of 450 to 2000 epileptic patients, giving an annual incidence of 0.55 to 9.3 per 1000 patients. Such a wide incidence range can be explained by the difficulties in providing a rigorous definition of sudden death and more importantly by the heterogeneous nature of the population at risk. The risk of sudden death is clearly related to the severity of the epilepsy. It is observed in young adults with symptomatic, often difficult to treat epilepsy. Death is frequently observed during sleep. PATHOPHYSIOLOGICAL HYPOTHESES: The circumstances of sudden death in the epileptic patient illustrate the complex relationships existing between seizures and irreversible cardiorespiratory dysfunction. Neurogenic lung edema is frequently observed at autopsy and has been confirmed by experimental data.

[Sudden death of epileptic patients]. DEFINITION: Sudden unexpected death in an epileptic patient which no likely cause--head trauma, drowning, grand mal, bronchial aspiration, suffocation--and no anatomic or toxicologic condition which could clearly explain the death. A seizure reported by witnesses or suspected from clinical signs observed prior to death and compatible with the definition raises the problematic of the relationship with sudden death. INCIDENCE AND RISK FACTORS: Sudden death is estimated to occur in 1 out of 450 to 2000 epileptic patients, giving an annual incidence of 0.55 to 9.3 per 1000 patients. Such a wide incidence range can be explained by the difficulties in providing a rigorous definition of sudden death and more importantly by the heterogeneous nature of the population at risk. The risk of sudden death is clearly related to the severity of the epilepsy. It is observed in young adults with symptomatic, often difficult to treat epilepsy. Death is frequently observed during sleep. PATHOPHYSIOLOGICAL HYPOTHESES: The circumstances of sudden death in the epileptic patient illustrate the complex relationships existing between seizures and irreversible cardiorespiratory dysfunction. Neurogenic lung edema is frequently observed at autopsy and has been confirmed by experimental data. Experimental work and clinical observations would suggest that central apnea, associated with cardiac dysrhythmia could be involved. Other risk factors, including sleep, compliance to treatment, arrhythmogenic effect of certain antiepileptics and the consequences of repeated seizures on the myocardium may also play a role.

Survival of patients with HUS and TTP has improved greatly over the past two decades with improved supportive care for patients with HUS and by the use of plasma exchange (PE) with fresh frozen plasma (FFP) for patients with TTP. Separate pathogenesis of these two disorders has become more evident, but management overlaps. OBJECTIVES: To evaluate the benefits and harms of different interventions for HUS and TTP separately, in patients of all ages. SEARCH STRATEGY: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), conference proceedings, reference lists of articles and text books and contact with investigators were used to identify relevant studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) evaluating any interventions for HUS or TTP in patients of all ages. DATA COLLECTION AND ANALYSIS: Three authors independently extracted data and evaluated study reporting quality using standard Cochrane criteria. Analysis was undertaken using a random effects model and results expressed as risk ratio (RR) and 95% confidence intervals (CI). MAIN RESULTS: For TTP, we found six RCTs (331 participants) evaluating PE with FFP as the control. Interventions tested included antiplatelet therapy (APT) plus PE with FFP, FFP transfusion and PE with cryosupernatant plasma (CSP). Two studies compared plasma infusion (PI) to PE with FFP and showed a significant increase in failure of remission at two weeks (RR 1.48, 95% 1.12 to 1.96) and all-cause mortality (RR 1.91, 95% 1.09 to 3.33) in the PI group. Seven RCTs were undertaken in children with HUS. None of the assessed interventions used (FFP transfusion, heparin with or without urokinase or dipyridamole, shiga toxin binding protein and steroids) were superior to supportive therapy alone, for all-cause mortality, neurological/extrarenal events, renal biopsy changes, proteinuria or hypertension at the last follow-up visit. Bleeding was significantly higher in those receiving anticoagulation therapy compared to supportive therapy alone (RR 25.89, 95% CI 3.67 to 182.83). AUTHORS' CONCLUSIONS: PE with FFP is still the most effective treatment available for TTP. For patients with HUS, supportive therapy including dialysis is still the most effective treatment. All studies in HUS have been conducted in the diarrhoeal form of the disease. There were no RCTs evaluating the effectiveness of any interventions on patients with atypical HUS who have a more chronic and relapsing course." ], "offsets": [ [ 87, 2750 ] ] } ]

Interventions for haemolytic uraemic syndrome and thrombotic thrombocytopenic purpura. BACKGROUND: Haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are related conditions with similar clinical features of variable severity. Survival of patients with HUS and TTP has improved greatly over the past two decades with improved supportive care for patients with HUS and by the use of plasma exchange (PE) with fresh frozen plasma (FFP) for patients with TTP. Separate pathogenesis of these two disorders has become more evident, but management overlaps. OBJECTIVES: To evaluate the benefits and harms of different interventions for HUS and TTP separately, in patients of all ages. SEARCH STRATEGY: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), conference proceedings, reference lists of articles and text books and contact with investigators were used to identify relevant studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) evaluating any interventions for HUS or TTP in patients of all ages. DATA COLLECTION AND ANALYSIS: Three authors independently extracted data and evaluated study reporting quality using standard Cochrane criteria. Analysis was undertaken using a random effects model and results expressed as risk ratio (RR) and 95% confidence intervals (CI). MAIN RESULTS: For TTP, we found six RCTs (331 participants) evaluating PE with FFP as the control. Interventions tested included antiplatelet therapy (APT) plus PE with FFP, FFP transfusion and PE with cryosupernatant plasma (CSP). Two studies compared plasma infusion (PI) to PE with FFP and showed a significant increase in failure of remission at two weeks (RR 1.48, 95% 1.12 to 1.96) and all-cause mortality (RR 1.91, 95% 1.09 to 3.33) in the PI group. Seven RCTs were undertaken in children with HUS. None of the assessed interventions used (FFP transfusion, heparin with or without urokinase or dipyridamole, shiga toxin binding protein and steroids) were superior to supportive therapy alone, for all-cause mortality, neurological/extrarenal events, renal biopsy changes, proteinuria or hypertension at the last follow-up visit. Bleeding was significantly higher in those receiving anticoagulation therapy compared to supportive therapy alone (RR 25.89, 95% CI 3.67 to 182.83). AUTHORS' CONCLUSIONS: PE with FFP is still the most effective treatment available for TTP. For patients with HUS, supportive therapy including dialysis is still the most effective treatment. All studies in HUS have been conducted in the diarrhoeal form of the disease. There were no RCTs evaluating the effectiveness of any interventions on patients with atypical HUS who have a more chronic and relapsing course.

METHODS: Participants underwent baseline in-clinic assessments, including the Unified Parkinson's Disease Rating Scale (UPDRS), and were provided smartphones with an Android operating system that contained a smartphone application that assessed voice, posture, gait, finger tapping, and response time. Participants then took the smart phones home to perform the five tasks four times a day for a month. Once a week participants had a remote (telemedicine) visit with a Parkinson disease specialist in which a modified (excluding assessments of rigidity and balance) UPDRS performed. Using statistical analyses of the five tasks recorded using the smartphone from 10 individuals with PD and 10 controls, we sought to: (1) discriminate whether the participant had PD and (2) predict the modified motor portion of the UPDRS. RESULTS: Twenty participants performed an average of 2.7 tests per day (68.9% adherence) for the study duration (average of 34.4 days) in a home and community setting. The analyses of the five tasks differed between those with Parkinson disease and those without. In discriminating participants with PD from controls, the mean sensitivity was 96.2% (SD 2%) and mean specificity was 96.9% (SD 1.9%).

Detecting and monitoring the symptoms of Parkinson's disease using smartphones: A pilot study. BACKGROUND: Remote, non-invasive and objective tests that can be used to support expert diagnosis for Parkinson's disease (PD) are lacking. METHODS: Participants underwent baseline in-clinic assessments, including the Unified Parkinson's Disease Rating Scale (UPDRS), and were provided smartphones with an Android operating system that contained a smartphone application that assessed voice, posture, gait, finger tapping, and response time. Participants then took the smart phones home to perform the five tasks four times a day for a month. Once a week participants had a remote (telemedicine) visit with a Parkinson disease specialist in which a modified (excluding assessments of rigidity and balance) UPDRS performed. Using statistical analyses of the five tasks recorded using the smartphone from 10 individuals with PD and 10 controls, we sought to: (1) discriminate whether the participant had PD and (2) predict the modified motor portion of the UPDRS. RESULTS: Twenty participants performed an average of 2.7 tests per day (68.9% adherence) for the study duration (average of 34.4 days) in a home and community setting. The analyses of the five tasks differed between those with Parkinson disease and those without. In discriminating participants with PD from controls, the mean sensitivity was 96.2% (SD 2%) and mean specificity was 96.9% (SD 1.9%). The mean error in predicting the modified motor component of the UPDRS (range 11-34) was 1.26 UPDRS points (SD 0.16). CONCLUSION: Measuring PD symptoms via a smartphone is feasible and has potential value as a diagnostic support tool.

PTH stimulates the production of 1,25-dihydroxyvitamin D [1,25(OH)2D] that in turn suppresses the synthesis of PTH in parathyroid cells. OBJECTIVE: The objective of the study was to clarify whether 1,25(OH)2D indeed inhibits circulating levels of PTH and influences bone turnover, even in a patient with primary hyperparathyroidism. DESIGN, SETTING, AND PATIENT: We evaluated PTH levels in a patient with primary hyperparathyroidism and coexistent sarcoidosis whose serum 1,25(OH)2D levels were independent of PTH. INTERVENTIONS AND MAIN OUTCOME MEASURES: The present case was treated with prednisolone before and after surgical resection of parathyroid adenoma, and Ca-regulating hormones and bone markers were measured. RESULTS: Serum Ca and PTH levels significantly decreased after parathyroid surgery, whereas serum 1,25(OH)2D levels remained high. Prednisolone administration promptly decreased serum 1,25(OH)2D levels and reciprocally increased PTH levels despite consistent serum Ca levels either before or after surgery. PTH levels were negatively correlated with serum 1,25(OH)2D levels before and after surgery. Urine N-telopeptides, serum osteocalcin, and bone-type alkaline phosphatase all decreased to physiological ranges after parathyroid surgery. CONCLUSIONS: These results suggest that 1,25(OH)2D indeed inhibits the production of PTH not to exacerbate hypercalcemia in a patient with primary hyperparathyroidism.

1,25-dihydroxyvitamin D suppresses circulating levels of parathyroid hormone in a patient with primary hyperparathyroidism and coexistent sarcoidosis. CONTEXT: PTH is excessively secreted to develop hypercalcemia and accelerate bone turnover in patients with primary hyperparathyroidism. PTH stimulates the production of 1,25-dihydroxyvitamin D [1,25(OH)2D] that in turn suppresses the synthesis of PTH in parathyroid cells. OBJECTIVE: The objective of the study was to clarify whether 1,25(OH)2D indeed inhibits circulating levels of PTH and influences bone turnover, even in a patient with primary hyperparathyroidism. DESIGN, SETTING, AND PATIENT: We evaluated PTH levels in a patient with primary hyperparathyroidism and coexistent sarcoidosis whose serum 1,25(OH)2D levels were independent of PTH. INTERVENTIONS AND MAIN OUTCOME MEASURES: The present case was treated with prednisolone before and after surgical resection of parathyroid adenoma, and Ca-regulating hormones and bone markers were measured. RESULTS: Serum Ca and PTH levels significantly decreased after parathyroid surgery, whereas serum 1,25(OH)2D levels remained high. Prednisolone administration promptly decreased serum 1,25(OH)2D levels and reciprocally increased PTH levels despite consistent serum Ca levels either before or after surgery. PTH levels were negatively correlated with serum 1,25(OH)2D levels before and after surgery. Urine N-telopeptides, serum osteocalcin, and bone-type alkaline phosphatase all decreased to physiological ranges after parathyroid surgery. CONCLUSIONS: These results suggest that 1,25(OH)2D indeed inhibits the production of PTH not to exacerbate hypercalcemia in a patient with primary hyperparathyroidism. Furthermore, PTH but not 1,25(OH)2D may primarily be involved in the stimulation of bone turnover.

The study was based on a community sample of 65 couples (130 men and women). The findings show that while there is no gender difference in the prevalence and incidence of verbal aggression, there is a difference in the levels of motivation to put one's partner \"in his or her place\" and avoid a confrontation with one's partner. Thus, there is a gender difference in escalatory tendency. This difference is evident in the greater motivation to put one's partner in his or her place observed among women, as compared with men, and in the lower motivation to avoid confrontation observed among women, as compared with men. Moreover, unlike among men, among women, the motivation to put one's partner in his place is higher than the motivation to avoid confrontation. It follows that the escalatory tendency among women is greater than the escalatory tendency among men.

Gender, Escalatory Tendencies, and Verbal Aggression in Intimate Relationships. This study examined the relationship between gender, escalatory tendencies, and the use of verbal aggression among four types of heterosexual dyads: couples with no verbal aggression, man-only verbal aggression, woman-only verbal aggression, and both-partner verbal aggression. The study was based on a community sample of 65 couples (130 men and women). The findings show that while there is no gender difference in the prevalence and incidence of verbal aggression, there is a difference in the levels of motivation to put one's partner "in his or her place" and avoid a confrontation with one's partner. Thus, there is a gender difference in escalatory tendency. This difference is evident in the greater motivation to put one's partner in his or her place observed among women, as compared with men, and in the lower motivation to avoid confrontation observed among women, as compared with men. Moreover, unlike among men, among women, the motivation to put one's partner in his place is higher than the motivation to avoid confrontation. It follows that the escalatory tendency among women is greater than the escalatory tendency among men. The findings also demonstrate significant gender differences in motivations and escalatory tendencies within the different types of dyads examined. These findings establish the relationship between escalation and aggression and also provide a glimpse into the mechanisms that sustain that relationship.

The history of the Prinzhorn collection illustrates many aspects of this interaction. Psychometric, psychodiagnostic and genetic research supports a link between creativity and psychiatric illness within the bipolar-psychotic continuum, with schizotypy/thymotypy as prototypes of creativity-related disorders. Evolutionary hypotheses connect the schizophrenia paradox to a survival advantage obtained as a result of enhanced creative ability. Neuro-aesthetics explains the neurologic correlates of the aesthetic experience on the basis of the features of the visual system. CONCLUSION: A specific challenge for scientific research in this complex and heterogeneous area is appropriate operationalisation of creativity and psychiatric illness within an truly artistic context. There is a continuing need for meaningful definitions and measurement instruments and for a multidisciplinary collaboration.

Effect of alcohol on the secretion of tumor necrosis factor-alpha by macrophages in the presence of rat serum. BACKGROUND: It is suggested that endotoxin, proinflammatory cytokines, and lipopolysaccharide-binding protein (LBP) play an important role in the development of alcoholic liver disease. Our previous study showed that splenic macrophages were important for endotoxin uptake and excessive production of tumor necrosis factor (TNF) in rats given large amounts of alcohol. To determine the pathophysiological roles of macrophages in alcoholic liver disease, we examined the effect of ethanol on TNF-alpha secretion of rat Kupffer cells, alveolar macrophages, and peritoneal macrophages in the presence or absence of LBP. METHODS: Kupffer cells, alveolar macrophages, and peritoneal macrophages were isolated from male Sprague Dawley rats. After the preculture in the medium containing 0, 10, 50, and 100 mmol/liter of ethanol, TNF-alpha secretion by these cells incubated with 100 ng/ml of endotoxin in the presence or absence of LBP (1% rat serum) was determined. RESULTS: In the absence of LBP, an addition of ethanol to the medium suppressed TNF-alpha secretion of alveolar macrophages. Kupffer cells and peritoneal macrophages were less affected. Addition of LBP led to marked enhancement (7- to 24-fold) of TNF-alpha secretion of macrophages either with or without ethanol in the medium. Although ethanol tended to suppress TNF-alpha secretion of these cells, alveolar macrophages were less affected in the presence of LBP. CONCLUSIONS: Serum LBP enhances the secretion of TNF-alpha by macrophages. Alveolar macrophages may be important for excessive production of TNF-alpha in chronic alcoholics with endotoxemia.

This technique offers technical advantages over the thrombin-clotting method, especially when measuring dilute solutions. Measurements made with the sulphite technique on fibrinogen solutions on plasma samples were not significantly different from those obtained with the thrombin-clotting method.

Gross and fine motor skills in children treated for acute lymphoblastic leukaemia. OBJECTIVE: Chemotherapy treatment for acute lymphoblastic leukaemia (ALL) may disrupt motor development, with suggestions that gross and fine motor deficits are different depending on time since treatment. METHODS: Thirty-seven participants aged between 2.5 to 5 years at the time of diagnosis were assessed using the Movement Assessment Battery for Children, 2nd Edition (MABC-2) and the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition, Short Form (BOT-2 SF), and divided into groups (i.e., months-off-treatment): (1) 0-12, (2) 13-24, and (3) 25-60 for comparison. RESULTS: MABC-2 and BOT-2 SF mean total scores fell within the average range. Twenty-six percent of the sample performed in the impaired range on the MABC-2. Group 2 had significantly lower Manual Dexterity scores than the normative population and lower BOT-2 SF scores than Group 1. CONCLUSION: Most children treated for ALL display appropriate motor skills, yet around a quarter experience general motor difficulties. Time-off-treatment did not affect the prevalence of motor impairments on any measure.

Cross-talk between human airway epithelial cells and 3T3-J2 feeder cells involves partial activation of human MET by murine HGF. There is considerable interest in the ex vivo propagation of primary human basal epithelial stem/progenitor cells with a view to their use in drug development, toxicity testing and regenerative medicine. These cells can be expanded in co-culture with mitotically inactivated 3T3-J2 murine embryonic feeder cells but, similar to other epithelial cell culture systems employing 3T3-J2 cells, the aspects of cross-talk between 3T3-J2 cells and human airway basal cells that are critical for their expansion remain largely unknown.

However, only a few genes that contribute to Cd resistance in plants have been identified. To identify additional Cd(II) resistance genes, we screened an Arabidopsis cDNA library using a yeast (Saccharomyces cerevisiae) expression system employing the Cd(II)-sensitive yeast mutant ycf1. This screening process yielded a small Cys-rich membrane protein (Arabidopsis plant cadmium resistance, AtPcrs). Database searches revealed that there are nine close homologs in Arabidopsis. Homologs were also found in other plants. Four of the five homologs that were tested also increased resistance to Cd(II) when expressed in ycf1.

A novel family of cys-rich membrane proteins mediates cadmium resistance in Arabidopsis. Cadmium (Cd) is a widespread pollutant that is toxic to plant growth. However, only a few genes that contribute to Cd resistance in plants have been identified. To identify additional Cd(II) resistance genes, we screened an Arabidopsis cDNA library using a yeast (Saccharomyces cerevisiae) expression system employing the Cd(II)-sensitive yeast mutant ycf1. This screening process yielded a small Cys-rich membrane protein (Arabidopsis plant cadmium resistance, AtPcrs). Database searches revealed that there are nine close homologs in Arabidopsis. Homologs were also found in other plants. Four of the five homologs that were tested also increased resistance to Cd(II) when expressed in ycf1. AtPcr1 localizes at the plasma membrane in both yeast and Arabidopsis. Arabidopsis plants overexpressing AtPcr1 exhibited increased Cd(II) resistance, whereas antisense plants that showed reduced AtPcr1 expression were more sensitive to Cd(II). AtPcr1 overexpression reduced Cd uptake by yeast cells and also reduced the Cd contents of both yeast and Arabidopsis protoplasts treated with Cd. Thus, it appears that the Pcr family members may play an important role in the Cd resistance of plants.

Case report: immunotherapy successfully treated brain metastasis in intrahepatic cholangiocarcinoma and literature review. Brain metastasis from intrahepatic cholangiocarcinoma (iCCA) is extremely rare, and no standard therapeutic strategy has been established. Camrelizumab is a programmed cell death protein 1 (PD-1) inhibitor that has been widely studied in treating liver cancer. Combined immunotherapy and targeted therapy are a promising approach for treating advanced iCCA. Despite that immune checkpoint inhibitor (ICI)-based neoadjuvant therapy on iCCA has shown a significant response rate and resection rate, few reports have shown the therapeutic efficacy of immunotherapy in treating brain metastasis from iCCA. Although PD-1 inhibitors such as pembrolizumab, nivolumab, or camrelizumab are increasingly applied in clinic practice to treat multiple malignancies, to the best of our knowledge, we report the first case of an iCCA patient with brain metastasis successfully treated with a combined immunotherapy and targeted therapy. The patient is a 54-year-old man with metastatic iCCA in brain treated though camrelizumab plus lenvatinib therapy with a complete response (CR). By the time of writing, he has had a progression-free survival of 17.5 months and did not experience any severe side effects related to this therapy. Camrelizumab plus lenvatinib therapy showed favorable efficacy and manageable toxicity for this patient with advanced iCCA and could be of interest for more prospective randomized trials to further verify the potential clinical benefits.

Nephrogenic adenoma in children. Nephrogenic adenoma is a rare, benign lesion of the bladder, occurring as an epithelial response to infection or trauma. Characteristically, it presents as a papillary lesion resembling a low grade, low stage transitional cell carcinoma. Although usually occurring in adults, there have been 5 reports in children, in whom the adenoma occurred following either surgery or localized inflammation. We report on 2 additional children with nephrogenic adenoma, including one who presented with a bladder mass and total occlusion of the ipsilateral ureter, while in the other it was found incidentally during closure of a vesicovaginal fistula. Successful treatment consisted of transurethral resection and low dose suppressive antibiotics. Nephrogenic adenoma, while rare in children, appears to be a uroepithelial metaplastic response to trauma or inflammation and is treated best by conservative management.

i4mC-EL: Identifying DNA N4-Methylcytosine Sites in the Mouse Genome Using Ensemble Learning. As one of important epigenetic modifications, DNA N4-methylcytosine (4mC) plays a crucial role in controlling gene replication, expression, cell cycle, DNA replication, and differentiation. The accurate identification of 4mC sites is necessary to understand biological functions. In the paper, we use ensemble learning to develop a model named i4mC-EL to identify 4mC sites in the mouse genome. Firstly, a multifeature encoding scheme consisting of Kmer and EIIP was adopted to describe the DNA sequences.

Although the pathogenesis of SLD is not clear, excessive fibrosis and inflammatory cell infiltration are the main histologic features of this disorder. Leukotrienes and lipoxins are two functionally different classes of lipoxygenase-derived eicosanoids. Leukotrienes are potent proinflammatory mediators and directly and indirectly stimulate fibroblast chemotaxis, proliferation, and collagen synthesis. Lipoxins counter-regulate the proinflammatory actions of leukotrienes and activate resolution of the inflammatory response. In addition, lipoxins inhibit growth-factor-induced fibroblast proliferation and collagen synthesis. Studies using bronchoalveolar lavage have revealed that there is an overproduction of proinflammatory and profibrotic leukotrienes in the lungs of patients with SLD, and that leukotriene levels correlate with inflammatory indices within the lungs. Moreover, the increased levels of leukotrienes in these patients are not balanced by an upregulation of anti-inflammatory and antifibrotic lipoxins. Unopposed actions of leukotrienes might, therefore, induce chronic inflammation and fibrosis in the lungs of SLD patients. Accordingly, pharmacologic correction of a leukotriene-lipoxin imbalance using leukotriene inhibitors or lipoxin analogs might be a new approach to the treatment of SLD." ], "offsets": [ [ 127, 1572 ] ] } ]

Mechanisms of Disease: leukotrienes and lipoxins in scleroderma lung disease--insights and potential therapeutic implications. Scleroderma interstitial lung disease (SLD) is a leading cause of morbidity and mortality in patients with systemic sclerosis. Although the pathogenesis of SLD is not clear, excessive fibrosis and inflammatory cell infiltration are the main histologic features of this disorder. Leukotrienes and lipoxins are two functionally different classes of lipoxygenase-derived eicosanoids. Leukotrienes are potent proinflammatory mediators and directly and indirectly stimulate fibroblast chemotaxis, proliferation, and collagen synthesis. Lipoxins counter-regulate the proinflammatory actions of leukotrienes and activate resolution of the inflammatory response. In addition, lipoxins inhibit growth-factor-induced fibroblast proliferation and collagen synthesis. Studies using bronchoalveolar lavage have revealed that there is an overproduction of proinflammatory and profibrotic leukotrienes in the lungs of patients with SLD, and that leukotriene levels correlate with inflammatory indices within the lungs. Moreover, the increased levels of leukotrienes in these patients are not balanced by an upregulation of anti-inflammatory and antifibrotic lipoxins. Unopposed actions of leukotrienes might, therefore, induce chronic inflammation and fibrosis in the lungs of SLD patients. Accordingly, pharmacologic correction of a leukotriene-lipoxin imbalance using leukotriene inhibitors or lipoxin analogs might be a new approach to the treatment of SLD.

We have studied the involvement of intracellular calcium and calcium-dependent signaling in the NPY-induced CRF release in trophoblastic cells. The incubation of trophoblasts with NPY for 3 and 8 h led to a dose-dependent increase in CRF secretion. Also, NPY stimulated synthesis of this peptide hormone upon an 8-h incubation period. BIBP3226, a selective Y1 receptor antagonist, and pertussis toxin (PTX) eliminated these effects. NPY-stimulated CRF secretion was mostly prevented by loading cells with BAPTA-AM, suggesting that elevation of intracellular calcium is responsible for the increase of CRF secretion. However, this calcium chelator had no effect on CRF synthesis. Furthermore, U-73122, a phospholipase C-betas (PLC) inhibitor or xestospongin C, an inositol triphosphate receptor (InsP3-R) blocker, have partially prevented the effect of NPY on CRF synthesis and secretion. Therefore, the increase in CRF synthesis and secretion rely in part on the release of calcium from intracellular store. Interestingly, SKF 96365, an inhibitor of store operated calcium (SOC) influx, also partially blocked the NPY stimulatory effect on CRF release but not its synthesis, suggesting that calcium influx is also involved in this stimulation. In the syncytiotrophoblast, known to possess a NPY-activated protein kinase C (PKCs) activity, NPY also stimulated calcium calmodulin kinase II (CaMKII) and extracellular regulated kinase (ERK1/2) activities. In the present study, we observed that bisindolylmaleimide (BIM), a nonspecific PKCs inhibitor partially prevented the NPY-induced CRF release. On the other hand, autocamtide-2 related inhibitory peptide (AIP), a CaMKII inhibitor, prevented most of the stimulatory effect of NPY on both CRF synthesis and release. Go6976, an inhibitor of the conventional and mu PKCs and PD 098059, an inhibitor of the ERK cascade, had no effect on neither CRF synthesis nor release. Altogether, these results support a Y1 receptor-mediated PTX-sensitive induction on CRF synthesis and release by NPY from human placental trophoblasts. The stimulation of CRF synthesis by NPY seems to depend mainly on a PLC-beta to InsP3-R axis and on CaMKII activity. Also, the release of CRF depends on the PLC-beta to InsP3-R axis and CaMKII activity but also entails the participation of a calcium-independent PKCs." ], "offsets": [ [ 132, 2552 ] ] } ]

Characterization of neuropeptide Y-mediated corticotropin-releasing factor synthesis and release from human placental trophoblasts. Neuropeptide Y (NPY) is a CRF secretagogue for human placental cells in culture. We have studied the involvement of intracellular calcium and calcium-dependent signaling in the NPY-induced CRF release in trophoblastic cells. The incubation of trophoblasts with NPY for 3 and 8 h led to a dose-dependent increase in CRF secretion. Also, NPY stimulated synthesis of this peptide hormone upon an 8-h incubation period. BIBP3226, a selective Y1 receptor antagonist, and pertussis toxin (PTX) eliminated these effects. NPY-stimulated CRF secretion was mostly prevented by loading cells with BAPTA-AM, suggesting that elevation of intracellular calcium is responsible for the increase of CRF secretion. However, this calcium chelator had no effect on CRF synthesis. Furthermore, U-73122, a phospholipase C-betas (PLC) inhibitor or xestospongin C, an inositol triphosphate receptor (InsP3-R) blocker, have partially prevented the effect of NPY on CRF synthesis and secretion. Therefore, the increase in CRF synthesis and secretion rely in part on the release of calcium from intracellular store. Interestingly, SKF 96365, an inhibitor of store operated calcium (SOC) influx, also partially blocked the NPY stimulatory effect on CRF release but not its synthesis, suggesting that calcium influx is also involved in this stimulation. In the syncytiotrophoblast, known to possess a NPY-activated protein kinase C (PKCs) activity, NPY also stimulated calcium calmodulin kinase II (CaMKII) and extracellular regulated kinase (ERK1/2) activities. In the present study, we observed that bisindolylmaleimide (BIM), a nonspecific PKCs inhibitor partially prevented the NPY-induced CRF release. On the other hand, autocamtide-2 related inhibitory peptide (AIP), a CaMKII inhibitor, prevented most of the stimulatory effect of NPY on both CRF synthesis and release. Go6976, an inhibitor of the conventional and mu PKCs and PD 098059, an inhibitor of the ERK cascade, had no effect on neither CRF synthesis nor release. Altogether, these results support a Y1 receptor-mediated PTX-sensitive induction on CRF synthesis and release by NPY from human placental trophoblasts. The stimulation of CRF synthesis by NPY seems to depend mainly on a PLC-beta to InsP3-R axis and on CaMKII activity. Also, the release of CRF depends on the PLC-beta to InsP3-R axis and CaMKII activity but also entails the participation of a calcium-independent PKCs.
