    Hypothalamic AgRP neurons potently coordinate feeding behavior to ensure an organism's viability. However, their acute role in glucose-regulatory function remains to be addressed. Steculorum et al. now report that activation of a specific set of AgRP neurons results in an impairment of insulin-stimulated glucose uptake in brown fat through a myogenic signature program.

    Full Text Available Acute glomerulonephritis (GNA is a wide group of diseases with the common characteristics of abrupt onset and proliferation of endocapillary glomerular cells. Clinically, they usually manifest as acute nephritic syndrome: hematuria, acute renal failure, hypertension and mild proteinuria, although they can appear as recurrent hematuria. GNA can be present in association with a variety of bacterial and viral infections, but in most cases the initial antigenic initiating stimulus is unknown. Patients with rapidly progressive glomerulonephritis often present acute onset of manifestations of nephritis, such as azotemia, oliguria, edema, hypertension, proteinuria, and hematuria with «active» urine sediment that often contains red blood cell casts, pigmented casts, and cellular debris. This article, aimed at all primary care staff and seeking to increase their awareness of this disease, discusses in more detail the clinical, pathogenesis, pathology, and treatments available from one of the glomerulonephritis with greater impact on survival patient.

    2007-08-01

    Full Text Available Abstract Background Dysphagia occurs in up to 50% of patients admitted to hospital with acute strokes with up to 27% remaining by seven days. Up to 8% continue to have swallowing problems six months after their stroke with 1.7% still requiring enteral feeding. Nasogastric tubes (NGT are the most commonly used method for providing enteral nutrition in early stroke, however they are easily and frequently removed leading to inadequate nutrition, early PEG (Percutaneous Endoscopic Gastrostomy insertion or abandoning of feeding attempts. Looped nasogastric tube feeding may improve the delivery of nutrition to such patients. Methods Three centre, two arm randomised controlled trial, with 50 participants in each arm comparing loop (the intervention versus conventional nasogastric tube feeding. The primary outcome measure is proportion of intended feed delivered in the first 2 weeks. The study is designed to show a mean increase of feed delivery of 16% in the intervention group as compared with the control group, with 90% power at a 5% significance level. Secondary outcomes are treatment failures, mean volume of feed received, adverse events, cost-effectiveness, number of chest x-rays, number of nasogastric tubes and tolerability.

    2015-01-01

    Full Text Available Background. The purpose of this study of preterm infants was to test the effect of four approaches to the time of transition from gavage to full oral feedings, time to discharge, and weight gain during the transition. Methods. A randomized experimental design was used with four intervention groups: early start (32 weeks’ postmenstrual age/slow progressing experience (gradually increasing oral feedings offered per day; early start/maximum experience (oral feedings offered at every feeding opportunity; late start (34 weeks’ postmenstrual age/slow progressing experience; and late start/maximum experience. Results. The analysis included 86 preterm infants. Once oral feedings were initiated, infants in the late start/maximum experience group achieved full oral feeding and were discharged to home significantly sooner than infants in either early start group. Although not significantly different, these infants also achieved these outcomes sooner than infants in the late start/slow progressing experience group. There were no differences in weight gain across groups. Conclusions. Results suggest starting oral feedings later in preterm infants may result in more rapid transition to full oral feedings and discharge although not at early postnatal ages. Provision of a more consistent approach to oral feeding may support infant neurodevelopment and reduce length of hospitalization.

  10. Role of macrophages in the progression of acute pancreatitis

    In addition to pancreatic cells,other inflammatory cell populations contribute to the generation of inflammatory mediators during acute pancreatitis.In particular,macrophages could be activated by mediators released during pancreatitis by a damaged pancreas.It has been reported that peritoneal macrophages,alveolar macrophages and Kupffer cells become activated in different stages of severe acute pancreatitis.However,macrophages display remarkable plasticity and can change their physiology in response to environmental cues.Depending on their microenvironmental stimulation,macrophages could follow different activation pathways resulting in marked phenotypic heterogeneity.This ability has made these cells interesting therapeutical targets and several approaches have been assayed to modulate the progression of inflammatory response secondary to acute pancreatitis.However,despite the recent advances in the modulation of macrophage function in vivo,the therapeutical applications of these strategies require a better understanding of the regulation of gene expression in these cells.

    Mortality from acute respiratory distress syndrome (ARDS) remains unacceptable, approaching 45% in certain high-risk patient populations. Treating fulminant ARDS is currently relegated to supportive care measures only. Thus, the best treatment for ARDS may lie with preventing this syndrome from ever occurring. Clinical studies were examined to determine why ARDS has remained resistant to treatment over the past several decades. In addition, both basic science and clinical studies were examined to determine the impact that early, protective mechanical ventilation may have on preventing the development of ARDS in at-risk patients. Fulminant ARDS is highly resistant to both pharmacologic treatment and methods of mechanical ventilation. However, ARDS is a progressive disease with an early treatment window that can be exploited. In particular, protective mechanical ventilation initiated before the onset of lung injury can prevent the progression to ARDS. Airway pressure release ventilation (APRV) is a novel mechanical ventilation strategy for delivering a protective breath that has been shown to block progressive acute lung injury (ALI) and prevent ALI from progressing to ARDS. ARDS mortality currently remains as high as 45% in some studies. As ARDS is a progressive disease, the key to treatment lies with preventing the disease from ever occurring while it remains subclinical. Early protective mechanical ventilation with APRV appears to offer substantial benefit in this regard and may be the prophylactic treatment of choice for preventing ARDS. PMID:26855896

  13. Feeding cues and injected nutrients induce acute expression of multiple clock genes in the mouse liver.

    Directory of Open Access Journals (Sweden)

    Hideaki Oike

    Full Text Available The circadian clock is closely associated with energy metabolism. The liver clock can rapidly adapt to a new feeding cycle within a few days, whereas the lung clock is gradually entrained over one week. However, the mechanism underlying tissue-specific clock resetting is not fully understood. To characterize the rapid response to feeding cues in the liver clock, we examined the effects of a single time-delayed feeding on circadian rhythms in the liver and lungs of Per2::Luc reporter knockin mice. After adapting to a night-time restricted feeding schedule, the mice were fed according to a 4, 8, or 13 h delayed schedule on the last day. The phase of the liver clock was delayed in all groups with delayed feeding, whereas the lung clock remained unaffected. We then examined the acute response of clock and metabolism-related genes in the liver using focused DNA-microarrays. Clock mutant mice were bred under constant light to attenuate the endogenous circadian rhythm, and gene expression profiles were determined during 24 h of fasting followed by 8 h of feeding. Per2 and Dec1 were significantly increased within 1 h of feeding. Real-time RT-PCR analysis revealed a similarly acute response in hepatic clock gene expression caused by feeding wild type mice after an overnight fast. In addition to Per2 and Dec1, the expression of Per1 increased, and that of Rev-erbα decreased in the liver within 1 h of feeding after fasting, whereas none of these clock genes were affected in the lung. Moreover, an intraperitoneal injection of glucose combined with amino acids, but not either alone, reproduced a similar hepatic response. Our findings show that multiple clock genes respond to nutritional cues within 1 h in the liver but not in the lung.

    International Renal Interest Society chronic kidney disease Stage 1 and acute kidney injury Grade I categorizations of kidney disease are often confused or ignored because patients are nonazotemic and generally asymptomatic. Recent evidence suggests these seemingly disparate conditions may be mechanistically linked and interrelated. Active kidney injury biomarkers have the potential to establish a new understanding for traditional views of chronic kidney disease, including its early identification and possible mediators of its progression, which, if validated, would establish a new and sophisticated paradigm for the understanding and approach to the diagnostic evaluation, and treatment of urinary disease in dogs and cats.

    Central oxytocin reduces food intake and increases energy expenditure. The ventromedial hypothalamic nucleus (VMN) is associated with energy balance and contains a high density of oxytocin receptors. We hypothesized that oxytocin in the VMN is a negative regulator of energy balance acting to reduce feeding and increase energy expenditure. To test this idea, oxytocin or vehicle was injected directly into the VMN of Sprague-Dawley rats during fasted and nonfasted conditions. Energy expenditure (via indirect calorimetry) and spontaneous physical activity (SPA) were recorded simultaneously. Animals were also exposed to a conditioned taste aversion test, to determine whether oxytocin's effects on food intake were associated with malaise. When food was available during testing, oxytocin-induced elevations in energy expenditure lasted for 1 h, after which overall energy expenditure was reduced. In the absence of food during the testing period, oxytocin similarly increased energy expenditure during the first hour, but differences in 12-h energy expenditure were eliminated, implying that the differences may have been due to the thermic effects of feeding (digestion, absorption, and metabolic processing). Oxytocin acutely elevated SPA and reduced feeding at doses that did not cause a conditioned taste aversion during both the fed and fasted states. Together, these data suggest that oxytocin in the VMN promotes satiety and acutely elevates energy expenditure and SPA and implicates the VMN as a relevant site for the antiobesity effects of oxytocin.

    Full Text Available Context Nasogastric tube feeding is safe and well tolerated in most critically ill patients. However, its safety and tolerance in the setting of severe acute pancreatitis is debatable. Objective We aimed to review all available studies on nasogastric feeding in patients with severe acute pancreatitis to determine the safety and tolerance of this approach. A further aim was to perform a meta-analysis of the available randomized controlled trials regarding nasogastric versus nasojejunal feeding. Methods Three electronic databases (Cochrane Central Register of Controlled Trials, EMBASE and MEDLINE and the abstracts of major gastroenterological meetings were reviewed. Meta-analysis was performed using the random effects model. Main outcome measures The summary estimates were reported as risk ratio (RR with 95% confidence interval (95% CI. Results A total of four studies on nasogastric tube feeding in 92 patients with predicted severe acute pancreatitis were identified. Documented infected pancreatic necrosis developed in 11 patients (16.9% and multiple organ failure in 10 (15.4% out of 65 patients with available data. Overall, there were 15 deaths (16.3%. An exacerbation of pain after initiation of feeding occurred in 3 (4.3% out of 69 patients with available data. Full tolerance was achieved in 73 (79.3% patients who did not require temporary reduction, stoppage or withdrawal of nasogastric feeding. The results of nasogastric feeding as compared to nasojejunal feeding, were no worse in terms of mortality (RR=0.77; 95% CI: 0.37 to 1.62; P=0.50 or intolerance of feeding (RR=1.09; 95% CI: 0.46 to 2.59; P=0.84. Conclusion Nasogastric feeding appears safe and well tolerated in patients with predicted severe acute pancreatitis. An adequately powered randomized trial on nasogastric versus nasojejunal feeding is required to support this approach as routine clinical management.

  19. Evidence for links between feeding inhibition, population characteristics, and sensitivity to acute toxicity for Daphnia magna.

    Science.gov (United States)

    Agatz, Annika; Brown, Colin D

    2013-08-20

    A population experiment with Daphnia magna tested the hypothesis that short-term feeding inhibition provokes a shift in population structure that will vary with conspecific pressure (e.g., pressure occurring from individuals of the same species due to competition for food and space) and increases population sensitivity to a xenobiotic exposure due to size-dependent toxicity (e.g., decreasing sensitivity with increasing body length). Populations were exposed for one week to a feeding inhibitor (imidacloprid, 0.15 or 12.0 mg/L) followed by one week of recovery and one day of exposure to an acute toxin (carbaryl, 0.0098 mg/L). Identical exposure under low and high conspecific pressure was studied by delaying the start of exposure for half of the populations by two weeks; thus populations were in a different stage of population development when exposure occurred. Feeding inhibition of 97% (12.0 mg/L imidacloprid) caused a shift in population structure toward smaller individuals but also reduced population abundance by up to 56 ± 7% with a strong influence of conspecific pressure. Increased population sensitivity to carbaryl was observed after feeding inhibition of 97% as hypothesized. Carbaryl exposure for one day resulted in population decline of up to 23 ± 6% when populations were not previously exposed to imidacloprid. Identical carbaryl exposure provoked a four times stronger decline in population abundance when exposure occurred following feeding inhibition of 97%. In conflict with the hypothesis, this was at least in part due to changes in the reproductive strategy of daphnids following exposure to imidacloprid rather than driven by the shift in population structure. The differences in population sensitivity to additional stress (carbaryl) occurring one week after feeding inhibition caused by exposure to imidacloprid adds a further challenge to understanding potential impacts from multiple stressors as occurring in the field at the population level.

    Full Text Available Progressive motor deficits are relatively common in acute pontine infarction and frequently associated with increased functional disability. However, the factors that affect the progression of clinical motor weakness are largely unknown. Previous studies have suggested that pontine infarctions are caused mainly by basilar artery stenosis and penetrating artery disease. Recently, lower pons lesions in patients with acute pontine infarctions have been reported to be related to progressive motor deficits, and ensuing that damage to the corticospinal tracts may be responsible for the worsening of neurological symptoms. Here, we review studies on motor weakness progression in pontine infarction and discuss the mechanisms that may underlie the neurologic worsening.

  8. Progress of feed-in tariff in Malaysia: A year after

    International Nuclear Information System (INIS)

    Malaysia enacted the Renewable Energy Act in April 2011. One of its important components is the feed-in tariff (FiT) scheme—launched in December 2011. The scheme is managed and administered by the Sustainable Energy Development Authority (SEDA) of Malaysia. This paper analyses the impact of the FiT mechanism in Malaysia a year after its implementation; particularly on the installation and economical aspects. First, the history of the scheme is presented before summarising the application process for the scheme. Next, a detailed evaluation on the implication of the scheme is discussed. Some of the key findings from the analysis include: (i) the uptake for renewable energy installations has been extremely high, particularly for solar photovoltaic installation; (ii) the foreign and domestic direct investment related to renewable sectors have increased significantly; (iii) more ‘green’ jobs have been created, particularly in the manufacturing and installation sectors, and (iv) there are plans to include wind and thermal energy in the FiT scheme. It can be concluded that the FiT scheme in Malaysia has produced significant impact during the first year of its implementation. With a proper monitoring by SEDA and more awareness among the people, renewable energy will most likely flourish in Malaysia. - Highlights: • Malaysia launched the feed-in tariff (FiT) scheme in December 2011. • The one year progress is evaluated in terms of installation and economical aspects. • The uptake for renewable energy installations has been extremely high. • Investment related to renewable sectors has increased significantly. • More ‘green’ jobs have been created in the country

  9. Unbiased transcriptional comparisons of generalist and specialist herbivores feeding on progressively defenseless Nicotiana attenuata plants.

    Directory of Open Access Journals (Sweden)

    Geetha Govind

    Full Text Available BACKGROUND: Herbivore feeding elicits dramatic increases in defenses, most of which require jasmonate (JA signaling, and against which specialist herbivores are thought to be better adapted than generalist herbivores. Unbiased transcriptional analyses of how neonate larvae cope with these induced plant defenses are lacking. METHODOLOGY/PRINCIPAL FINDINGS: We created cDNA microarrays for Manduca sexta and Heliothis virescens separately, by spotting normalized midgut-specific cDNA libraries created from larvae that fed for 24 hours on MeJA-elicited wild-type (WT Nicotiana attenuata plants. These microarrays were hybridized with labeled probes from neonates that fed for 24 hours on WT and isogenic plants progressively silenced in JA-mediated defenses (N: nicotine; N/PI: N and trypsin protease inhibitors; JA: all JA-mediated defenses. H. virescens neonates regulated 16 times more genes than did M. sexta neonates when they fed on plants silenced in JA-mediated defenses, and for both species, the greater the number of defenses silenced in the host plant (JA > N/PI > N, the greater were the number of transcripts regulated in the larvae. M. sexta larvae tended to down-regulate while H. virescens larvae up- and down-regulated transcripts from the same functional categories of genes. M. sexta larvae regulated transcripts in a diet-specific manner, while H. virescens larvae regulated a similar suite of transcripts across all diet types. CONCLUSIONS/SIGNIFICANCE: The observations are consistent with the expectation that specialists are better adapted than generalist herbivores to the defense responses elicited in their host plants by their feeding. While M. sexta larvae appear to be better adapted to N. attenuata's defenses, some of the elicited responses remain effective defenses against both herbivore species. The regulated genes provide novel insights into larval adaptations to N. attenuata's induced defenses, and represent potential targets for plant

  10. Acute respiratory infections in Pakistan: Have we made any progress?

    International Nuclear Information System (INIS)

    Acute respiratory infections (ARI) are the leading cause of death in young children in Pakistan, responsible for 20-30% of child deaths under age 5 years. This paper summarizes the research and technical development efforts over the last 15 years which have contributed to improving the effectiveness of the case management strategy to reduce mortality from 5' pneumonia in children in Pakistan. Community intervention is viable, effective and practical. Rising antimicrobial resistance among commonly used and A low-cost oral agent is of significant concern. Appropriate monitoring and evaluation of the impact of the ARI control programme is lacking. Lack of funding for programmatic activities, lack of coordination with other child survival programs, inadequate training for community health workers and general practitioners in the private sector, lack of public awareness about seeking timely and appropriate care and insufficient planning and support for ARI in the programmatic activities at provincial and district levels are major hindrances in decreasing the burden of ARI in the country. The recent introduction of the community-based Lady Health Worker (LHW) Programme and WHO and UNICEF-sponsored integrated management of childhood illness initiative present ideal opportunities for re-emphasizing early case detection and appropriate case management of ARI. Ultimately, focusing on preventive strategies such as improving nutrition, reducing indoor pollution, improving mass vaccination, as well as introduction of new vaccines effective against important respiratory pathogens will likely have the most impact on reducing severe ARI and deaths from severe disease.

    Background: exclusive breastfeeding has been shown to protect infants from contracting various diseases. The aims of this study were: to examine the relationships between infant feeding patterns and the risk of Acute Respiratory Infections (ARI, and to assess the importance of some factors that can increase such risk.

    Methods: a case-control study was carried out during the period between February 1st 2005 - May 1st 2005. The study included 137 infants who were hospitalized in the Children Welfare Teaching Hospital for ARIs during the period of study (a case definition of acute lower respiratory infection as given by the WHO (1995 was used. The Control group included 157 healthy infants who were randomly selected from two primary health care centers of the AI-Karkh sector of Baghdad for immunization. The risk of various factors thought to be associated to ARI were studied, these being: non-modifiable (age, gender, birth order, parent education, crowded residence, family history of asthma and history of ARIs in household members in previous 2 weeks and modifiable (short duration of breastfeeding, cigarette smoking in proximity to the infant, delayed immunization and malnutrition. Logistic regression was used to adjust for confounders and for calculating adjusted odds ratios.

    Results: formula fed infants had a 2.7 times higher risk (CI:1.6-4.68 for ARIs compared to breast fed infants. Infants who had undergone a short duration of breastfeeding (<3 months had a 1.4 times increased risk or ARI (CI: 0.89—2.23. Additional factors that were associated with higher ARIs were, female gender (OR= 2.0, CI:1.3-3.3, low educational level of mothers (OR= 6.4, CI:3.2-12.7 and fathers (OR=4.5, CI:2.27-8.78, crowded residence (OR= 4.5, CI: 2.6-7.8, positive history of ARIs in household members in the 2 weeks prior to the study (OR= 5.5, CI:3.3-9.3, family history of asthma (OR = 2.6, CI:1

    BACKGROUND: Acute pancreatitis (AP) is a common acute abdomen with high mortality, multiple complications and complicated causes. There is no effective therapy for AP. Radix salviae miltiorrhizae (Danshen), a traditional herbal medicine, has a low price and a wide range of clinical applications. It is effective to promote blood lfow, eliminate stagnancy, and relieve pain. It is also found to be effective in treating AP. We reviewed the progress in research into the mechanism of Radix salviae miltiorrhizae in treatment of AP. DATA SOURCES: An english-language literature search was conducted using MEDLINE (1988-2005) on Radix salviae miltiorrhizae (Danshen) and acute pancreatitis. RESULTS:The mechanisms of Danshen in the treatment of AP include improvement of microcirculatory disturbances;elimination of oxygen free radicals; modulation of the metabolism of lipid inlfammatory mediator;and blocking of calcium inlfow and prevention of calcium overload. CONCLUSION:Danshen can effectively reduce the mortality and complications of AP.

    Full Text Available Objective To investigate the MRI abnormalities and acute madopar responsiveness test in diagnosing progressive supranuclear palsy (PSP and Parkinson's disease (PD. Methods Seventeen patients with PSP and 17 gender and age matched patients with PD were studied with cranial MRI examinations and results of acute madopar responsiveness test, and the clinical manifestations of PSP were summarized. Results The atrophy of the midbrain tegmentum and hummingbird sign was demonstrated in all of the PSP patients in our study, but was not observed in the PD patients. The areas of the midbrain on mid-sagittal MRI in PSP patients [(77.35 ± 15.30 mm2] were significantly smaller than that in those with PD [(142.35 ± 31.49 mm2]. The average ratio of the area of the midbrain to the area of pons in the patients with PSP [(14.31 ± 2.47%] was significantly smaller than that in those with PD [(24.08 ± 4.73%; P = 0.000, for all]. According to the result of acute madopar responsiveness test, the maximum Unified Parkinson's Disease Rating Scale (UPDRS Ⅲ improvement rate of 2 patients with PSP and 16 patients with PD was more than 30% (χ2 = 23.142, P = 0.000. Conclusion The assessment of the mid-sagittal MRI and acute madopar responsiveness test may be a useful method to differentiate PSP from PD.

    AL amyloidosis is a clonal plasma cell proliferative disorder characterised by extracellular tissue deposits of insoluble fibrils derived from κ or λ immunoglobulin light chains. The most common organs affected by AL amyloidosis are the kidney, presenting with nephrotic syndrome and/or progressive renal dysfunction, and the heart, with restrictive cardiomyopathy. Hepatic deposition of fibrils occurs in half the cases but the liver is rarely the predominantly affected organ. The most common presentation of hepatic amyloidosis is hepatomegaly with elevated alkaline phosphatase. Acute liver failure with cholestasis and jaundice is a rare complication, with a prevalence of approximately 5%, and is usually associated with a worse prognosis. We report a case of a 39-year-old man admitted to our nephrology department with an unusual presentation of primary amyloidosis with nephrotic syndrome and acute liver failure, complicated by obstructive cholestasis resulting in death 2 months after diagnosis.

    Full Text Available BACKGROUND: Early diagnosis is vital to HIV control. γδ T cells play critical roles in viral infections, but their activation in acute HIV infected patients and follow up to 18 months has not been described. METHODS: Changes in γδ T cells, including subsets, function and activation, in treated and untreated acutely HIV-infected patients (n = 79 were compared by cytotoxicity assay and flow cytometry with healthy controls (n = 21 at month 0, 6, 12 and 18. RESULTS: In acutely HIV-infected patients, Vδ1 cell proportion was elevated (P = 0.027 with Vδ2 population reduced (P = 0.002. Effector and central memory γδ T cell factions were decreased (P = 0.006 and P = 0.001, respectively, while proportion of terminal γδ T cells increased (P = 0.002. γδ T cell cytotoxicity was compromised over time. Fraction of IL-17-producing cells increased (P = 0.008, and IFN-γ-producing cells were unaffected (P = 0.115. Elevation of a microbial translocation marker, sCD14, was associated with γδ T cell activation (P = 0.001, which increased in a time-dependent manner, correlating with CD4/CD8 T cell activation set-points and CD4 counts. Antiretroviral therapy did not affect these changes. CONCLUSIONS: γδ T cell subpopulation and functions change significantly in acute HIV infection and over time. Early γδ T cell activation was associated with CD4/CD8 T cell activation set-points, which predict AIDS progression. Therefore, γδ T cell activation represents a potential surrogate marker of AIDS progression.

    2007-01-01

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes ofvasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

    The cytokine interferon-gamma (IFNgamma) is implicated in the induction of acute CNS inflammation, but it is less clear what role if any IFNgamma plays in progression to chronic demyelination and neurological deficit. To address this issue, we have expressed IFNgamma in myelinating oligodendrocytes....... In contrast to control mice, which remit from EAE with resolution of glial reactivity and leukocytic infiltration, transgenics showed chronic neurological deficits. While activated microglia/macrophages persisted in demyelinating lesions for over 100 days, CD4(+) T lymphocytes were no longer present in CNS...

    Cancer progresses with a change in the structure of the gene network in normal cells. We define a measure of organizational hierarchy in gene networks of affected cells in adult acute myeloid leukemia (AML) patients. With a retrospective cohort analysis based on the gene expression profiles of 116 AML patients, we find that the likelihood of future cancer relapse and the level of clinical risk are directly correlated with the level of organization in the cancer related gene network. We also explore the variation of the level of organization in the gene network with cancer progression. We find that this variation is non-monotonic, which implies the fitness landscape in the evolution of AML cancer cells is non-trivial. We further find that the hierarchy in gene expression at the time of diagnosis may be a useful biomarker in AML prognosis. PMID:25685944

    Wound healing consists of three overlapping phases: inflammation, proliferation, and matrix synthesis and remodeling. Prolonged alcohol abuse can cause liver fibrosis due to deregulated matrix remodeling. Previous studies demonstrated that moderate ethanol feeding enhances liver fibrogenic markers and frank fibrosis independent of differences in CCl₄-induced liver injury. Our objective was to determine whether or not other phases of the hepatic wound healing response were affected by moderate ethanol after CCl₄ exposure. Mice were fed moderate ethanol (2% v/v) for two days and then were exposed to CCl₄ and euthanized 24-96 h later. Liver injury was not different between pair- and ethanol-fed mice; however, removal of necrotic tissue was delayed after CCl₄-induced liver injury in ethanol-fed mice. Inflammation, measured by TNFα mRNA and protein and hepatic Ly6c transcript accumulation, was reduced and associated with enhanced hepatocyte apoptosis after ethanol feeding. Hepatocytes entered the cell cycle equivalently in pair- and ethanol-fed mice after CCl₄ exposure, but hepatocyte proliferation was prolonged in livers from ethanol-fed mice. CCl₄-induced hepatic stellate cell activation was increased and matrix remodeling was prolonged in ethanol-fed mice compared to controls. Taken together, moderate ethanol affected each phase of the wound healing response to CCl₄. These data highlight previously unknown effects of moderate ethanol exposure on hepatic wound healing after acute hepatotoxicant exposure.

    Objective To determine the occurrence of neurological changes during the first 48 hours after acute stroke as it relates to the initial stroke severity assessment. Methods The assessment with the National Institutes of Health Stroke Scale (NIHSS) was performed serially for the first 48 hours on 68 consecutive ischemic stroke patients admitted to the Department of Geriatric Cardiology at the Khanh Hoa Hospital, Nha Trang, Vietnam. Incidence of stroke progression (a ≥ 3-point increase on the NIHSS) was recorded and analysis performed to determine its association with initial stroke severity and other demographic and physiological variables. Deficit resolution by 48 hours, defined as an NIHSS score of 0 or 1, measured the frequency of functional recovery predicted by the initial deficit.Results Overall progression was noted in 28% of events (19/68). Applying Bayes' solution to the observed frequency of worsening, the greatest likelihood of predicting future patient progression occurred with NIHSS score of =7 and >7. Patients with an initial NIHSS score of =7 experienced a 13% (6/47) worsening rate versus those of an initial score of>7 with a 62% (13/21) worsening rate (P<0.01). 42.5%(20/47) of those with an initial score of =7 were functionally normal at 48 hours, whereas only 4.7% (1/21) of those with scores of >7 retnrned to a normal examination within this period (x2, P<0.05). Conclusions This study suggests that the early clinical course of neurological deficit after acute stroke be dependent on the initial stroke severity and that a dichotomy in early outcome exist surrounding an initial NIHSS score of 7. These findings may have significant implications for the design and patient stratification in treatment protocols with respect to primary clinical outcome.

    This study was done to investigate the effects of acute intermittent hypoxia (IH) on metabolic factors associated with energy balance and body weight, and on hypothalamic satiety-inducing pathways. Adult male Sprague-Dawley rats were exposed to either 8h IH or normoxic control conditions. Food intake, locomotion and body weights were examined after IH. Additionally, plasma levels of leptin, adiponectin corticosterone, insulin and blood glucose were measured following exposure to IH. Furthermore, adipose tissue was removed and analyzed for leptin and adiponectin content. Finally, the hypothalamic arcuate nucleus (ARC) was assessed for alterations in protein signaling associated with satiety. IH reduced body weight, food intake and active cycle locomotion without altering adipose tissue mass. Leptin protein content was reduced while adiponectin content was elevated in adipose tissue after IH. Plasma concentration of leptin was significantly increased while adiponectin decreased after IH. No changes were found in plasma corticosterone, insulin and blood glucose. In ARC, phosphorylation of signal transducer and activator of transcription-3 and pro-opiomelanocortin (POMC) expression were elevated. In addition, POMC-expressing neurons were activated as determined by immediate early gene FRA-1/2 expression. Finally, ERK1/2 and its phosphorylation were reduced in response to IH. These data suggest that IH induces significant alterations to body energy balance through changes in the secretion of leptin which exert effects on satiety-inducing pathways within the hypothalamus.

  7. Acute coagulopathy of trauma: balancing progressive catecholamine induced endothelial activation and damage by fluid phase anticoagulation

    DEFF Research Database (Denmark)

    Johansson, P I; Ostrowski, S R

    2010-01-01

    Acute coagulopathy of trauma predicts a poor clinical outcome. Tissue trauma activates the sympathoadrenal system resulting in high circulating levels of catecholamines that influence hemostasis dose-dependently through immediate effects on the two major compartments of hemostasis, i.e., the...... circulating blood and the vascular endothelium. There appears to be a dose-dependency with regards to injury severity and the hemostatic response to trauma evaluated in whole blood by viscoelastic assays like thrombelastography (TEG), changing from normal to hypercoagulable, to hypocoagulable and finally...... evolutionary developed response that counterbalances the injury and catecholamine induced endothelial activation and damage. Given this, the rise in circulating catecholamines in trauma patients may favor a switch from hyper- to hypocoagulability in the blood to keep the progressively more procoagulant...

  8. Feed-in tariffs versus quotas: how to promote renewable s and stimulate technical progress for cost decrease?

    International Nuclear Information System (INIS)

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

    Since progressive hemorrhagic injury (PHI) was introduced in neurosurgical literatures, several studies have been performed, the results of which have influenced doctors but do not define guidelines for the best treatment of PHI. PHI may be confirmed by a serial computerized tomography (CT) scan, and it has been shown to be associated with a fivefold increase in the risk of clinical worsening and is a significant cause of morbidity and mortality as well. So, early detection of PHI is practically important in a clinical situation. To analyze the early CT signs of progressive hemorrhagic injury following acute traumatic brain injury (TBI) and explore their clinical significances, PHI was confirmed by comparing the first and repeated CT scans. Data were analyzed and compared including times from injury to the first CT and signs of the early CT scan. Logistic regression analysis was used to show the risk factors related to PHI. A cohort of 630 TBI patients was evaluated, and there were 189 (30%) patients who suffered from PHI. For patients with their first CT scan obtained as early as 2 h post-injury, there were 116 (77.25%) cases who suffered from PHI. The differences between PHIs and non-PHIs were significant in the initial CT scans showing fracture, subarachnoid hemorrhage (SAH), brain contusion, epidural hematoma (EDH), subdural hematoma (SDH), and multiple hematoma as well as the times from injury to the first CT scan (P < 0.01). Logistic regression analysis showed that early CT scans (EDH, SDH, SAH, fracture, and brain contusion) were predictors of PHI (P < 0.01). For patients with the first CT scan obtained as early as 2 h post-injury, a follow-up CT scan should be performed promptly. If the initial CT scan shows SAH, brain contusion, and primary hematoma with brain swelling, an earlier and dynamic CT scan should be performed for detection of PHI as early as possible and the medical intervention would be enforced in time.

    Objective: In acute pancreatitis, traditional treatment insists fasting on purpose to avoid activation of proteolytic enzymes and pancreatic enzyme secretion. The aim of our study was to evaluate the efficacy and feasibility of early oral feeding as compared to traditional fasting in patients with mild acute pancreatitis.Methods: Seventy-two patients were randomized to the two treatment groups, fasting or early oral feeding. The inclusion criteria were pancreas amylase≥3times above normal, onset of abdominal pain within 48h, acute physiological and chronic health evaluation-II score<8 and C-reactive protein(CRP)<150 mg/L. Measures were amylase, systemic inflammatory response, length of hospital stay. Results: The groups were comparable with respect to age, sex, etiology, APACHE II, time from onset of pain and amylase at admission. No significant differences were seen between the groups concerning levels of amylase, CRP, leukocytes, abdominal pain or number of gastrointestinal symptoms. The length of hospital stay time was significantly shorter in the oral feeding group (13 vs. 17 days; P<0.05).Conclusion: Early oral feeding would not exacerbate disease process. The differences between treatment groups for amylase or systemic inflammatory response were not obvious. In mild acute pancreatitis, early oral feeding was feasible and safe and may accelerate recovery.%目的: 比较轻型胰腺炎病人早期摄食与禁食两种治疗措施的安全性和对病情转归的影响.方法: 将72例急性轻型胰腺炎病人随机分为A(早期摄食)组与B(禁食治疗)组.对入选病人治疗过程中,淀粉酶水平、炎症反应和平均住院时间进行评价.结果: A组病人淀粉酶水平、C反应蛋白、WBC计数、腹痛或消化道症状与B组无显著性差异,但平均住院时间明显缩短(P<0.05).结论: 在急性轻型胰腺炎病人的治疗过程中,采取早期摄食不仅不会加重病情,而且还会促进病人康复.

    Most cancers evolve over time as patients initially responsive to therapy acquire resistance to the same drugs at relapse. Cancer stem cells have been postulated to represent a therapy-refractory reservoir for relapse, but formal proof of this model is lacking. We prospectively characterized leukemia stem cell populations (LSCs) from a well-defined cohort of patients with acute myelogenous leukemia (AML) at diagnosis and relapse to assess the effect of the disease course on these critical populations. Leukemic samples were collected from patients with newly diagnosed AML before therapy and after relapse, and LSC frequency was assessed by limiting dilution analyses. LSC populations were identified using fluorescent-labeled cell sorting and transplantation into immunodeficient NOD/SCID/interleukin 2 receptor γ chain null mice. The surface antigen expression profiles of pretherapy and postrelapse LSCs were determined for published LSC markers. We demonstrate a 9- to 90-fold increase in LSC frequency between diagnosis and relapse. LSC activity at relapse was identified in populations of leukemic blasts that did not demonstrate this activity before treatment and relapse. In addition, we describe genetic instability and exceptional phenotypic changes that accompany the evolution of these new LSC populations. This study is the first to characterize the evolution of LSCs in vivo after chemotherapy, identifying a dramatic change in the physiology of primitive AML cells when the disease progresses. Taken together, these findings provide a new frame of reference by which to evaluate candidate AML therapies in which both disease control and the induction of more advanced forms of disease should be considered.

    Anne-Sophie Liovat

    Full Text Available T cell activation levels, viral load and CD4(+ T cell counts at early stages of HIV-1 infection are predictive of the rate of progression towards AIDS. We evaluated whether the inflammatory profile during primary HIV-1 infection is predictive of the virological and immunological set-points and of disease progression. We quantified 28 plasma proteins during acute and post-acute HIV-1 infection in individuals with known disease progression profiles. Forty-six untreated patients, enrolled during primary HIV-1 infection, were categorized into rapid progressors, progressors and slow progressors according to their spontaneous progression profile over 42 months of follow-up. Already during primary infection, rapid progressors showed a higher number of increased plasma proteins than progressors or slow progressors. The plasma levels of TGF-β1 and IL-18 in primary HIV-1 infection were both positively associated with T cell activation level at set-point (6 months after acute infection and together able to predict 74% of the T cell activation variation at set-point. Plasma IP-10 was positively and negatively associated with, respectively, T cell activation and CD4(+ T cell counts at set-point and capable to predict 30% of the CD4(+ T cell count variation at set-point. Moreover, plasma IP-10 levels during primary infection were predictive of rapid progression. In primary infection, IP-10 was an even better predictor of rapid disease progression than viremia or CD4(+ T cell levels at this time point. The superior predictive capacity of IP-10 was confirmed in an independent group of 88 HIV-1 infected individuals. Altogether, this study shows that the inflammatory profile in primary HIV-1 infection is associated with T cell activation levels and CD4(+ T cell counts at set-point. Plasma IP-10 levels were of strong predictive value for rapid disease progression. The data suggest IP-10 being an earlier marker of disease progression than CD4(+ T cell counts or

    Malnutrition is common in patients with acute and chronic illness. Nutritional management of these malnourished patients is an essential part of healthcare. Enteral feeding is one component of nutritional support. It is the preferred method of nutritional support in patients that are not receiving adequate oral nutrition and have a functioning gastrointestinal tract (GIT). This method of nutritional support has undergone progression over recent times. The method of placement of enteral feedin...

  18. Progress of imaging research on the early diagnosis of acute osteomyelitis

    International Nuclear Information System (INIS)

    The imaging diagnostic techniques include X-ray plain film, ultrasound, CT, MRI and radionuclide imaging. X-ray plain film is less sensitive to early acute osteomyelitis. Ultrasound can detect abscesses in the soft tissues and subperiosteal space earlier, but there are variations in image quality based on the different operators' levels of proficiency. High-resolution CT can find minimal lesions on bone, but it has a low sensitivity to predict acute osteomyelitis. MRI is superior to other imaging techniques at visualizing bone marrow lesions, but it is less sensitive in detecting sequestrum and calcification than CT. A variety of radionuclide imaging agents have been used in the early diagnosis of acute osteomyelitis in order to find a more sensitive and specific imaging technique. In this paper, different imaging diagnostic techniques of acute osteomyelitis are reviewed. (authors)

    The effects of Dissostichus mawsoni-Calmodulin (Dm-CaM) on growth performance, enzyme activities, respiratory burst, MDA level and immune-related gene expressions of the orange-spotted grouper (Epinephelus coioides) exposed to the acute low temperature stress were evaluated. The commercial diet supplemented with Dm-CaM protein was fed to the groupers for 6 weeks. No significant difference was observed in the specific growth rates, weight gains and survivals. After the feeding trial, the groupers were exposed to acute low temperature challenge. The groupers fed with Dm-CaM additive diet showed a significant decrease in the respiratory burst activity, while the blood cell number increased significantly at 25 °C by comparing with the control and additive control group. The enzymatic activity of SOD, ACP and ALP increased significantly in Dm-CaM additive group, while MDA level maintained stable with the lowest value. qRT-PCR analysis indicated that the up-regulated transcript expressions of CaM, C3, SOD2, LysC and HSPA4 were observed in Dm-CaM additive group. These results indicated that Dm-CaM additive diet may regulate the grouper immune response to the acute low temperature challenge.

    Full Text Available 80 cytological preparations derived by fibrogastroduodenoscopy from 20 patients with cerebrospinal trauma at cervical part level served as the research subject. Dynamics of the progression of acute erosive ulcered lesions of mucous membrane of the upper parts of the gastrointestinal tract was studied on the basis of the cytological analyses of mucous membrane biopsy materials. In the course of our work we used endoscopic (fibrogastroduodenoscopy and cytological research methods. Cytological analyses of mucous membrane biopsy materials were carried out on the 7th, 14th, 21st and 28th day. Biopsy material cellular composition was evaluated on the grounds of the calculation of neutrophilic leukocytes and epithelial cells with the use of an immersion objective. In so doing we registered neutrophilic leukocyte number for 100 cells and determined neutrophilic and epithelial index. Monitoring of neutrophilic leukocyte number enables to determine presence or absence of inflammatory changes in stomach mucous membrane and duodenum in different periods of cerebrospinal trauma

    The aim of this study was to assess individual differences in temperament and stress response and quantify their impact on feed efficiency, performance, and methane (CH4) emissions in beef cattle. Eighty-four steers (castrated males) (Charolais or Luing) were used. Temperament was assessed using two standardized tests: restlessness when restrained [crush score (CS)] and flight speed (FS) on release from restraint. Over a 56-day period individual animal dry matter intake (DMI) and weekly body weight was measured. Ultrasound fat depth was measured at the end of 56 days. Average daily gain (ADG), feed conversion ratio (FCR), and residual feed intake (RFI) were calculated. After the 56-day test period, animals were transported in groups of six/week to respiration chamber facilities. Blood samples were taken before and 0, 3, 6, and 9 h after transport. Plasma cortisol, creatine kinase (CK), glucose, and free fatty acids (FFA) were determined to assess physiological stress response. Subsequently, CH4 emissions were measured over a 3-day period in individual respiration chambers. CS (1.7 ± 0.09) and FS (1.6 ± 0.60 m/s) were repeatable (0.63 and 0.51, respectively) and correlated (r = 0.36, P animals (FS; P = 0.032) and higher stress response (cortisol, P = 0.007; FFA, P = 0.007; and CK, P = 0.003) were associated with lower DMI. ADG was lower in more temperamental animals (CS, P = 0.097, and FS, P = 0.030). Fat depth was greater in steers showing calmer CS (P = 0.026) and lower plasma CK (P = 0.058). Temperament did not show any relationship with RFI or CH4 emissions. However, steers with higher cortisol showed improved feed efficiency (lower FCR and RFI) (P feed intake that may both increase the efficiency of consumed feed and the ratio of CH4 emissions/unit of feed. Therefore, temperament and stress response should be considered when designing strategies to improve efficiency and mitigate CH4 emissions in beef

    AIM: To utilize transcatheter arterial steroid injection therapy (TASIT) via the hepatic artery to reduce hepatic macrophage activity in patients with severe acute hepatic failure.METHODS: Thirty-four patients with severe acute hepatic failure were admitted to our hospital between June 2002 to June 2006 providing for the possibility of liver transplantation (LT). Seventeen patients were treated using traditional liver supportive procedures, and the other 17 patients additionally underwent TASIT with 1000 mg methylprednisolone per day for 3 continuous days.RESULTS: Of the 17 patients who received TASIT, 13 were cured without any complications, 2 died, and 2 underwent LT. Of the 17 patients who did not receive TASIT, 4 were self-limiting, 7 died, and 6 underwent LT.Univariate logistic analysis revealed that ascites, serum albumin, prothrombin time, platelet count, and TASIT were significant variables for predicating the prognosis.Multivariate logistic regression analysis using stepwise variable selection showed that prothrombin time, platelet count, and TASIT were independent predictive factors.CONCLUSION: TASIT might effectively prevent the progression of severe acute hepatic failure to a fatal stage of fulminant liver failure.

    Full Text Available Context :Current best evidence is in favour of early institution of enteral feeding in acute severe pancreatitis with promising results from trials in immunonutrition on other patient groups. Objective: To identify which groups of patients and products are associated with benefit, we investigated immunonutrition in patients with predicted acute severe pancreatitis. Design :A randomised trial of a study feed containing glutamine, arginine, tributyrin and antioxidants versus an isocaloric isonitrogenous control feed was undertaken. Patients: Thirty-one patients with a diagnosis of acute pancreatitis predicted to develop severe disease: 15 study feeds and 16 control feeds. Interventions: Enteral feeding via nasojejunal tube for 3 days. If patients required further feeding the study was continued up to 15 days. Main outcome measures :Reduction in Creactive protein (CRP by 40 mg/L after 3 days of enteral feeding was the primary endpoint. Carboxypeptidase B activation peptide (CAPAP levels were taken at regular intervals. Results :After 3 days of feeding, in the study group 2/15 (13% of patients had reduced their CRP by 40 mg/L or more. In the control group 6/16 (38% of patients had reduced their CRP by this amount. This difference was found to be near the statistical significant limit (P=0.220. Conclusions :The cause of the unexpectedly higher CRP values in the study group is unclear. The rise in CRP was without a commensurate rise in CAPAP or outcome measures so there was no evidence that this represented pancreatic necrosis. The contrast between the CRP and CAPAP results is of interest and we believe that specific pancreatic indices such as CAPAP should be considered in larger future studies.

  16. Superconducting open-gradient magnetic separation for the pretreatment of radioactive or mixed waste vitrification feeds. 1997 annual progress report

    International Nuclear Information System (INIS)

    'Vitrification has been selected as a final waste form technology in the US for long-term storage of high-level radioactive wastes (HLW). However, a foreseeable problem during vitrification in some waste feed streams lies in the presence of elements (e.g., transition metals) in the HLW that may cause instabilities in the final glass product. The formation of spinel compounds, such as Fe3O4 and FeCrO4, results in glass phase separation and reduces vitrifier lifetime, and durability of the final waste form. A superconducting open gradient magnetic separation (OGMS) system maybe suitable for the removal of the deleterious transition elements (e.g. Fe, Co, and Ni) and other elements (lanthanides) from vitrification feed streams due to their ferromagnetic or paramagnetic nature. The OGMS systems are designed to deflect and collect paramagnetic minerals as they interact with a magnetic field gradient. This system has the potential to reduce the volume of HLW for vitrification and ensure a stable product. In order to design efficient OGMS and High gradient magnetic separation (HGMS) processes, a fundamental understanding of the physical and chemical properties of the waste feed streams is required. Using HLW simulant and radioactive fly ash and sludge samples from the Savannah River Technology Center, Rocky Flats site, and the Hanford reservation, several techniques were used to characterize and predict the separation capability for a superconducting OGMS system.'

    BACKGROUND Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil's disease. CASE REPORT A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient's condition drastically improved after initiation of doxycycline. On subsequent days, the patient's Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. CONCLUSIONS As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis presenting as Weil's disease is a common cause of renal and hyperbilirubinemia in endemic areas. Often, as was the case for our patient where the time from presentation to acute

    Full Text Available The rotifer Brachionus sp. is commonly used for larval feeding in marine fish hatcheries. The aim of this study was to evaluate whether the inclusion of Acartia tonsa nauplii in the initial diet of carapeva larvae improves their survival, growth and resistance to stress when compared to the regimen containing only rotifers. Adult copepods were collected in the wild and cultured with the microalgae Chaetoceros muelleri, Isochrysis galbana and Nannochloropsis oculata to obtain nauplii. Carapeva larvae were grown for 15 days using four treatments and three replicates: 1 Brachionus plicatilis rotifers (10 to 15/mL; 2 A. tonsa nauplii (0.25 to 0.5/mL; 3 Brachionus plicatilis rotifers (5 to 7.5/mL + A. tonsa nauplii (0.12 to 0.25/mL, and 4 no supply of live feed. After 15 days, the carapeva larvae were subjected to stress by exposure to air for 10 seconds and then returned to the source tank to evaluate survival after 24 h. Survival and stress resistance were higher in carapeva larvae fed B. plicatilis + A. tonsa nauplii (P<0.05, 20.9 ± 11.2% and 88.9%, respectively. These results confirm the positive effect of the inclusion of copepod nauplii in the diet of fish larvae. However, more research is needed to validate these results.

Anxiety-related parameters decreased in RJ vs. RW mice. Rotarod latency times increased 72 h post-TBI in RJ vs RW mice. No overall changes in food and drink intake were observed along the experimental period. On the irradiation day, bout number was increased and bout duration was decreased in RW mice. The changes were reversed by purple grape juice intake. Grape juice intake before and after TBI can overcome several radiation-induced changes in behaviour within 24-72 hours after sub-lethal X-irradiation. This beneficial effect on short-term anxiety and mobility-related activities could probably be included in the list of flavonoid bio-effects. The present findings could be relevant in designing preventive interventions aimed to enhance body defense mechanisms against short-term irradiation damage.

  1. Dopaminergic modulation of effort-related choice behavior as assessed by a progressive ratio chow feeding choice task: pharmacological studies and the role of individual differences.

    Full Text Available Mesolimbic dopamine (DA is involved in behavioral activation and effort-related processes. Rats with impaired DA transmission reallocate their instrumental behavior away from food-reinforced tasks with high response requirements, and instead select less effortful food-seeking behaviors. In the present study, the effects of several drug treatments were assessed using a progressive ratio (PROG/chow feeding concurrent choice task. With this task, rats can lever press on a PROG schedule reinforced by a preferred high-carbohydrate food pellet, or alternatively approach and consume the less-preferred but concurrently available laboratory chow. Rats pass through each ratio level 15 times, after which the ratio requirement is incremented by one additional response. The DA D(2 antagonist haloperidol (0.025-0.1 mg/kg reduced number of lever presses and highest ratio achieved but did not reduce chow intake. In contrast, the adenosine A(2A antagonist MSX-3 increased lever presses and highest ratio achieved, but decreased chow consumption. The cannabinoid CB1 inverse agonist and putative appetite suppressant AM251 decreased lever presses, highest ratio achieved, and chow intake; this effect was similar to that produced by pre-feeding. Furthermore, DA-related signal transduction activity (pDARPP-32(Thr34 expression was greater in nucleus accumbens core of high responders (rats with high lever pressing output compared to low responders. Thus, the effects of DA antagonism differed greatly from those produced by pre-feeding or reduced CB1 transmission, and it appears unlikely that haloperidol reduces PROG responding because of a general reduction in primary food motivation or the unconditioned reinforcing properties of food. Furthermore, accumbens core signal transduction activity is related to individual differences in work output.

    The earliest description of what is now known as the acute respiratory distress syndrome (ARDS) was a highly lethal double pneumonia. Ashbaugh and colleagues (Ashbaugh DG, Bigelow DB, Petty TL, Levine BE Lancet 2: 319-323, 1967) correctly identified the disease as ARDS in 1967. Their initial study showing the positive effect of mechanical ventilation with positive end-expiratory pressure (PEEP) on ARDS mortality was dampened when it was discovered that improperly used mechanical ventilation can cause a secondary ventilator-induced lung injury (VILI), thereby greatly exacerbating ARDS mortality. This Synthesis Report will review the pathophysiology of ARDS and VILI from a mechanical stress-strain perspective. Although inflammation is also an important component of VILI pathology, it is secondary to the mechanical damage caused by excessive strain. The mechanical breath will be deconstructed to show that multiple parameters that comprise the breath-airway pressure, flows, volumes, and the duration during which they are applied to each breath-are critical to lung injury and protection. Specifically, the mechanisms by which a properly set mechanical breath can reduce the development of excessive fluid flux and pulmonary edema, which are a hallmark of ARDS pathology, are reviewed. Using our knowledge of how multiple parameters in the mechanical breath affect lung physiology, the optimal combination of pressures, volumes, flows, and durations that should offer maximum lung protection are postulated.

    2010-06-01

    Reperfusion therapy for acute myocardial infarction has dramatically reduced mortality. Coronary angioplasty and thrombolysis are the most effective reperfusion techniques. The controversy about which of the two methods is best has been superseded by a search for the most rapid and effective way of inducing reperfusion, given the overriding importance of time for saving myocardial tissue. Consequently, pharmaco-invasive strategies, prehospital thrombolysis and rapid patient transport systems have all been implemented. Typically, a certain percentage of patients do not undergo reperfusion for a range of reasons, one of the most important being treatment delay. Trends in Latin America are similar to those in other parts of the world: there is an increasing use of angioplasty instead of thrombolysis and a significant number of patients do not undergo reperfusion. Some patient registries indicate that hospital mortality tends to be higher than in Europe or the United States. There are numerous reasons for the difference, among which are a delay in presentation and a lack of access to properly equipped hospitals because of social inequality. Scientific societies have a key role to play in promoting awareness about the importance of early diagnosis and treatment throughout the health-care community, health authorities, and society in general.

    Highlights: • Ethanol administration increased GPD1 mRNA expression. • Ethanol administration increased glucose incorporation into TG glycerol moieties. • No increase in hepatic TG levels was observed in ethanol-injected GPD1 null mice. • We propose that GPD1 is required for ethanol-induced TG accumulation in the liver. - Abstract: Acute ethanol consumption leads to the accumulation of triglycerides (TGs) in hepatocytes. The increase in lipogenesis and reduction of fatty acid oxidation are implicated as the mechanisms underlying ethanol-induced hepatic TG accumulation. Although glycerol-3-phosphate (Gro3P), formed by glycerol kinase (GYK) or glycerol-3-phosphate dehydrogenase 1 (GPD1), is also required for TG synthesis, the roles of GYK and GPD1 have been the subject of some debate. In this study, we examine (1) the expression of genes involved in Gro3P production in the liver of C57BL/6J mice in the context of hepatic TG accumulation after acute ethanol intake, and (2) the role of GPD1 in the progression of ethanol-induced fatty liver using GPD1 null mice. As a result, in C57BL/6J mice, ethanol-induced hepatic TG accumulation began within 2 h and was 1.7-fold greater than that observed in the control group after 6 h. The up-regulation of GPD1 began 2 h after administering ethanol, and significantly increased 6 h later with the concomitant escalation in the glycolytic gene expression. The incorporation of {sup 14}C-labelled glucose into TG glycerol moieties increased during the same period. On the other hand, in GPD1 null mice carrying normal GYK activity, no significant increase in hepatic TG level was observed after acute ethanol intake. In conclusion, GPD1 and glycolytic gene expression is up-regulated by ethanol, and GPD1-mediated incorporation of glucose into TG glycerol moieties together with increased lipogenesis, is suggested to play an important role in ethanol-induced hepatic TG accumulation.

    Enteral nutrition comprises the delivery of a liquid formula beyond the esophagus via a feeding tube in a patient with insufficient oral intake, as well as the provision of specialized nutritional formula irrespective of the route of delivery. Pediatric formulae have been designed for different age groups, and for children with certain diseases; examples are special formulations for regurgitating infants, metabolic diseases, cow's milk or multiple food allergies, intestinal, pancreatic, renal, and hepatic insufficiency. Exclusive enteral nutrition is a therapeutic concept to induce remission in children and adolescents with active Crohn's disease. A new area of nutritional research in pediatrics is potential immunonutrition in critically ill children. Formulae are enriched with single components or a combination of key substrates that might play a crucial role during intermediary metabolism in sepsis, inflammation, tissue healing, and growth. For pharmaconutrition, single components are investigated in a scientific stepwise procedure in order to identify effective disease-dedicated nutrition therapy. Any new formula needs to be evaluated, if possible in comparison to a normal diet or the reference formulation to demonstrate its safety and efficacy (equal or superior to standard formula).

  8. Analysis of the effects of exposure to acute hypoxia on oxidative lesions and tumour progression in a transgenic mouse breast cancer model

    International Nuclear Information System (INIS)

    Tumour hypoxia is known to be a poor prognostic indicator, predictive of increased risk of metastatic disease and reduced survival. Genomic instability has been proposed as one of the potential mechanisms for hypoxic tumour progression. Both of these features are commonly found in many cancer types, but their relationship and association with tumour progression has not been examined in the same model. To address this issue, we determined the effects of 6 week in vivo acute hypoxic exposure on the levels of mutagenic lipid peroxidation product, malondialdehyde, and 8-oxo-7,8-dihydro-2'-deoxyguanosine DNA (8-oxo-dG) lesions in the transgenic polyomavirus middle T (PyMT) breast cancer mouse model. We observed significantly increased plasma lipid peroxidation and 8-oxo-dG lesion levels in the hypoxia-exposed mice. Consumption of malondialdehyde also induced a significant increase in the PyMT tumour DNA lesion levels, however, these increases did not translate into enhanced tumour progression. We further showed that the in vivo exposure to acute hypoxia induced accumulation of F4/80 positive tumour-associated macrophages (TAMs), demonstrating a relationship between hypoxia and macrophages in an experimental model. These data suggest that although exposure to acute hypoxia causes an increase in 8-oxo-dG lesions and TAMs in the PyMT tumours, these increases do not translate into significant changes in tumour progression at the primary or metastatic levels in this strong viral oncogene-driven breast cancer model

    Previous results indicated that miR-146b-5p is downregulated by TAL1, a transcription factor critical for early hematopoiesis that is frequently overexpressed in T-cell acute lymphoblastic leukemia (T-ALL) where it has an oncogenic role. Here, we confirmed that miR-146b-5p expression is lower in TAL1-positive patient samples than in other T-ALL cases. Furthermore, leukemia T-cells display decreased levels of miR-146b-5p as compared to normal T-cells, thymocytes and other hematopoietic progenitors. MiR-146b-5p silencing enhances the in vitro migration and invasion of T-ALL cells, associated with increased levels of filamentous actin and chemokinesis. In vivo, miR-146b overexpression in a TAL1-positive cell line extends mouse survival in a xenotransplant model of human T-ALL. In contrast, knockdown of miR-146b-5p results in leukemia acceleration and decreased mouse overall survival, paralleled by faster tumor infiltration of the central nervous system. Our results suggest that miR-146b-5p is a functionally relevant microRNA gene in the context of T-ALL, whose negative regulation by TAL1 and possibly other oncogenes contributes to disease progression by modulating leukemia cell motility and disease aggressiveness.

    Full Text Available Introduction: There is no significant difference between NFHS II &III with respect to under- nutrition data but Gross national income has increased many times, so poverty and unavailability of food alone cannot be the only reasons of under- nutrition. Under-nutrition is the result of many interrelated factors such as poverty, insufficient household food security, inadequate health services, poor maternal and child care practices and inadequate water and sanitation. For communities with a high prevalence of under- nutrition, it may take years or even decades before all of these factors can be addressed. Aims and Objectives:  to find out child feeding practices responsible for severe acute malnutrition among Under-five Children and to recommend a Community Action Plan based on Positive Deviance Approach to deal with under-nutrition quickly, affordably and sustainably in a culturally acceptable manner. Materials & Methods: Study design: Matched Case Control study. Sample size: 143 cases and age, socio-economic status matched 143 controls. Study place: MTC and Immunization clinic. Study Duration: May, 2013- May, 2014. Study Tool and Data Collection: Semi-structured pre-tested questionnaire. Data analysis: with help of SPSS16 (Mean, SD, Proportion, odds ratio. Results: Strong positive association was found between duration of exclusive breast feeding(both shorter and longer, prelacteals, diluted milk as weaning food, bottle feeding, giving excess milk and less solid protein diet, not able to recognize cue of hunger by mother, lack of demand feeding, and severe acute malnutrition. Conclusion: Not any nutritional programme can help in preventing SAM unless we motivate the mothers for good child feeding and rearing practices. This can be achieved by identification of the Positive Deviant mothers from the same community and SES, who can motivate the mothers of SAM children and can practically demonstrate positive child feeding practices in a culturally

    Full Text Available The current study evaluates the impact of high fructose feeding in rat model of gentamicin induced nephrotoxicity. Sprague-Dawley rats weighing 180–200 g were randomized into four groups; (C received standard rodents chow with free access to ad libitum drinking water for 8 weeks and was considered as control, (F received standard rodents chow with free access to drinking water supplemented with 20% (W/V fructose for the same abovementioned period, (FG was fed as group F and was given 80 mg/kg (body weight/day gentamicin sulphate intraperitoneally during the last 20 days of the feeding period, and (G was given gentamicin as above and fed as group C. Renal function was assessed at the end of the treatment period through measuring serum creatinine, uric acid and albumin, creatinine clearance, absolute and fractional excretion of both sodium and potassium, twenty-four-hour urinary excretion of albumin, and renal histology. For metabolic syndrome assessment, fasting plasma glucose and insulin were measured and oral glucose tolerance test was performed throughout the treatment period. Results showed that gentamicin enhances progression of fructose induced metabolic syndrome. On the other hand, fructose pretreatment before gentamicin injection produced a comparable degree of renal dysfunction to those which were given fructose-free water but the picture of nephrotoxicity was somewhat altered as it was characterized by higher extent of glomerular congestion and protein urea. Overall, more vigilance is required when nephrotoxic drugs are prescribed for patients with fructose induced metabolic syndrome.

    The value of perfusion MRI for identifying the tissue at risk has been questioned. Our objective was to assess baseline perfusion-weighted imaging parameters within infarct progression areas. Patients with anterior circulation stroke without early reperfusion were included from a prospective MRI database. Sequential MRI examinations were performed on admission, 2-3 h (H2), 2-3 days (D2), and between 15 and 30 days after the initial MRI. Maps of baseline time-to-peak (TTP), mean transit time (MTT), cerebral blood volume (CBV), and cerebral blood flow (CBF) were calculated. Lesion extension areas were defined as pixels showing de novo lesions between each MRI and were generated by subtracting successive lesion masks: V{sub 0}, baseline diffusion-weighted imaging (DWI) lesion; V{sub 1}, lesion extension between baseline and H2 DWI; V{sub 2}, lesion extension from H2 to D2 DWI; and V{sub 3}, lesion extension from D2 DWI to final FLAIR. Repeated measures analysis was used to compare hemodynamic parameters within the baseline diffusion lesion and subsequent lesion extension areas. Thirty-two patients were included. Baseline perfusion parameters were significantly more impaired within the acute DWI lesion compared to lesion extension areas (TTP, p<0.0001; MTT, p<0.0001; CBF p<0.0001; CBV, p<0.0001). A significant decrease in MTT (p = 0.01) and TTP (p = 0.01) was found within successive lesion growth areas. A decreasing gradient of severity for TTP and MTT was observed within successive infarct growth areas. (orig.)

  15. The onset of the progression of acute phase response mechanisms induced by extreme impacts can be followed by the decrease in blood levels of positive acute phase proteins.

    Larina, Olga; Bekker, Anna

    Studies performed at space flights and earth-based simulation models detected the plasma indices of acute phase reaction (APR), i.e. the increase of APR cytokine mediators and alterations in the production of blood acute phase proteins (APP) at the initial stages of adaptation to altered gravity conditions. Acute phase response is the principal constituent of the functional activity of innate immunity system. Changes in plasma APPs contents are considered to serve the restoration of homeostasis state. According to trends of their concentration shifts at the evolving of acute phase reaction APPs are denoted as positive, neutral, or negative. Plasma concentrations of positive acute phase proteins α1-acid glycoprotein (α1-AGP), α1-antitrypsin (α1-AT), and neutral α2-macroglobulin (α2-M) were measured in human study at 12-hour antiorthostatic position (AOP) with 15° head down tilt and hypoxia experiments at 14% oxygen in pressure chamber. Both of these impacts were shown to produce alterations in the APP levels indicative for acute phase response. Nevertheless, in AOP experiment noticeable decrease in α1-AGP concentration occurred by hour 12, and even more pronounced decline of α1-AGP and α1-AT were found on hypoxia hours 12 and 36. Acute phase proteins α1-AGP and α2-M possess the features of proteinase inhibitors. This function is implemented by the formation of complexes with the molecules of proteolytic enzymes which subsequently are removed from the blood flow. Transient decrease in plasma concentrations of protease inhibitors on early phases of APR development was reported to result from the growth of plasma protease activity due to cathepsin release from activated leukocytes, which had not yet been compensated by enhanced APP synthesis. Being a carrier protein for positively charged and neutral substances, α1-AGP shows pronounced elevation in its blood content during APR development. As assumed, it is required for the transportation of the increased

    Full Text Available Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations of reinforcement value and response costs. Furthermore, people with major depression and other disorders often show anergia, psychomotor retardation, fatigue, and alterations in effort-related decision making.

    Behavioral activation is a fundamental feature of motivation, and organisms frequently make effort-related decisions based upon evaluations of reinforcement value and response costs. Furthermore, people with major depression and other disorders often show anergia, psychomotor retardation, fatigue, and alterations in effort-related decision making. Tasks measuring effort-based decision making can be used as animal models of the motivational symptoms of depression, and the present studies characterized the effort-related effects of the vesicular monoamine transport (VMAT-2) inhibitor tetrabenazine.

    POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) syndrome is a rare cause of demyelinating neuropathy with monoclonal plasma cell proliferation, and POEMS neuropathy is usually chronically progressive. Herein, the authors report a 34-year-old woman with POEMS syndrome presenting as acute polyneuropathy. Within 2 weeks of disease onset, she became unable to walk with electrodiagnostic features of demyelination and was initially diagnosed as having Guillan-Barré syndrome. Other systemic features (oedema and skin changes) developed later, and an elevated serum level of vascular endothelial growth factor led to the diagnosis of POEMS syndrome. She received high-dose chemotherapy with autologous peripheral blood stem cell transplantation, resulting in good recovery. The authors also reviewed patterns and speed of progression of neuropathy in the 30 patients with POEMS syndrome; 22 (73%) of them were unable to walk independently with the median period of 9.5 months from POEMS onset (range 0.5-51 months). Whereas the speed of neuropathy progression varies considerably among patients, some POEMS patients can show acute or subacute polyneuropathy. The early diagnosis and treatment could result in rapid improvement as shown in the present patient.

    OBJECTIVE: All forms of commonly practiced enteral feeding techniques stimulate pancreatic secretion, and only intravenous feeding avoids it. In this study, we explored the possibility of more distal enteral infusions of tube feeds to see whether activation of the ileal brake mechanism can result...... in enteral feeding without pancreatic stimulation, with particular reference to trypsin, because the avoidance of trypsin stimulation may optimize enteral feeding in acute pancreatitis. METHODS: The pancreatic secretory responses to feeding were studied in 36 healthy volunteers by standard double...... in plasma glucagon-like peptide-1 and peptide YY concentrations. CONCLUSIONS: Our results suggest that enteral feeding can be given without stimulating pancreatic trypsin secretion provided it is delivered into the mid-distal jejunum. The mechanism may involve activation of the ileal brake mechanism....

    Chronic inflammatory disorders are thought to arise due to an interplay between predisposing host genetics and environmental factors. For example, the onset of inflammatory bowel disease is associated with enteric proteobacterial infection, yet the mechanistic basis for this association is unclear. We have shown previously that genetic defiency in TLR1 promotes acute enteric infection by the proteobacteria Yersinia enterocolitica. Examining that model further, we uncovered an altered cellular immune response that promotes the recruitment of neutrophils which in turn increases metabolism of the respiratory electron acceptor tetrathionate by Yersinia. These events drive permanent alterations in anti-commensal immunity, microbiota composition, and chronic inflammation, which persist long after Yersinia clearence. Deletion of the bacterial genes involved in tetrathionate respiration or treatment using targeted probiotics could prevent microbiota alterations and inflammation. Thus, acute infection can drive long term immune and microbiota alterations leading to chronic inflammatory disease in genetically predisposed individuals.

    Rats' performance on a progressive-ratio schedule maintained by sucrose (0.6M, 50 μl) and corn oil (100%, 25 μl) reinforcers was assessed using a model derived from Killeen's (1994) theory of schedule-controlled behaviour, 'Mathematical Principles of Reinforcement'. When the rats were maintained at 80% of their free-feeding body weights, the parameter expressing incentive value, a, was greater for the corn oil than for the sucrose reinforcer; the response-time parameter, δ, did not differ between the reinforcer types, but a parameter derived from the linear waiting principle (T0), indicated that the minimum post-reinforcement pause was longer for corn oil than for sucrose. When the rats were maintained under free-feeding conditions, a was reduced, indicating a reduction of incentive value, but δ was unaltered. Under the food-deprived condition, the CB1 cannabinoid receptor agonist Δ(9)-tetrahydrocannabinol (THC: 0.3, 1 and 3 mg kg(-1)) increased the value of a for sucrose but not for corn oil, suggesting a selective enhancement of the incentive value of sucrose; none of the other parameters was affected by THC. The results provide new information about the sensitivity of the model's parameters to deprivation and reinforcer quality, and suggest that THC selectively enhances the incentive value of sucrose.

  10. Acute chlorine gas exposure produces transient inflammation and a progressive alteration in surfactant composition with accompanying mechanical dysfunction

    International Nuclear Information System (INIS)

    Acute Cl2 exposure following industrial accidents or military/terrorist activity causes pulmonary injury and severe acute respiratory distress. Prior studies suggest that antioxidant depletion is important in producing dysfunction, however a pathophysiologic mechanism has not been elucidated. We propose that acute Cl2 inhalation leads to oxidative modification of lung lining fluid, producing surfactant inactivation, inflammation and mechanical respiratory dysfunction at the organ level. C57BL/6J mice underwent whole-body exposure to an effective 60 ppm-hour Cl2 dose, and were euthanized 3, 24 and 48 h later. Whereas pulmonary architecture and endothelial barrier function were preserved, transient neutrophilia, peaking at 24 h, was noted. Increased expression of ARG1, CCL2, RETLNA, IL-1b, and PTGS2 genes was observed in bronchoalveolar lavage (BAL) cells with peak change in all genes at 24 h. Cl2 exposure had no effect on NOS2 mRNA or iNOS protein expression, nor on BAL NO3− or NO2−. Expression of the alternative macrophage activation markers, Relm-α and mannose receptor was increased in alveolar macrophages and pulmonary epithelium. Capillary surfactometry demonstrated impaired surfactant function, and altered BAL phospholipid and surfactant protein content following exposure. Organ level respiratory function was assessed by forced oscillation technique at 5 end expiratory pressures. Cl2 exposure had no significant effect on either airway or tissue resistance. Pulmonary elastance was elevated with time following exposure and demonstrated PEEP refractory derecruitment at 48 h, despite waning inflammation. These data support a role for surfactant inactivation as a physiologic mechanism underlying respiratory dysfunction following Cl2 inhalation. - Highlights: • Effect of 60 ppm*hr Cl2 gas on lung inflammation and mechanical function examined. • Pulmonary inflammation is transient and minor. • Alterations in surfactant homeostasis and pulmonary mechanics

    Full Text Available Background: Ossification of the posterior longitudinal ligament (OPLL and cervical disc herniation are commonly encountered neurosurgical conditions. Here we present an unusual case of nontraumatic rapidly progressive myelopathy due to cervical disc herniation with comorbid OPLL and conduct a literature review focusing on the frequency and management of disc herniations with OPLL. Case Description: A 52-year-old healthy female presented with a 72-h history of rapid progression of dense quadriparesis with sensory deficits, with a precedent 4-week history of nontraumatic midline neck pain. Clinical examination revealed profound motor deficits below the C5 myotome. Spinal neuroimaging revealed OPLL (computed tomography [CT] and a cervical disc herniation spanning from C4/5 to C5/6 with significant retrovertebral disease (magnetic resonance imaging [MRI]. Operative management involved an anterior cervical corpectomy and instrumented fusion, with removal of both the sequestered disc material and the locally compressive OPLL. The patient recovered full motor function and independent ambulation with no residual signs or symptoms of myelopathy at the time of discharge. Conclusion: This unique case of a spontaneous cervical disc herniation in the context of OPLL causing rapidly progressive myelopathy illustrates the complementarity of CT and MRI in diagnosing the underlying cause of a rapidly progressive neurologic deficit in the absence of antecedent trauma. Though the optimal surgical management of such pathology remains uncertain; in this case, the anterior approach was motivated by the significant retrovertebral ventrally compressive sequestrum, and provided for excellent neurologic outcome. This article also reviews the occurrence/management of such acute cervical discs with OPLL.

Patients with AMI often have anemia. According to reports, the incidence of anemia in patients with AMI is between 6% and 43% . After AMI there is a decrease in the concentration of hemoglobin in the blood, which adds to myocardial ischemia and may cause cardiac dysrhythmias thereby increasing the infarction are-a. At the same time, it increases cardiac output and the oxygen consumption of myocardial cells. Anemia after AMI can increase the progression of heart failure and increase mortality. This article reviews the clinical research on anemia after acute myocardial infarction.

  15. Calpastatin overexpression prevents progression of S-1,2-dichlorovinyl-L-cysteine (DCVC)-initiated acute renal injury and renal failure (ARF) in diabetes

    International Nuclear Information System (INIS)

    Previously we have shown that 90% of streptozotocin (STZ)-induced type-1 diabetic (DB) mice survive from acute renal failure (ARF) and death induced by a normally LD9 dose (75 mg/kg, i.p.) of the nephrotoxicant S-1,2-dichlorovinyl-L-cysteine (DCVC). This remarkable protection is due to a combination of slower progression of DCVC-initiated renal injury and increased compensatory nephrogenic tissue repair in the DB kidneys. BRDU immunohistochemistry revealed that the DB condition led to 4-fold higher number of proximal tubular cells (PTC) entering S-phase of cell cycle. In the present study, we tested the hypothesis that DB-induced augmentation of PTC into S-phase is accompanied by overexpression of the calpain-inhibitor calpastatin, which endogenously prevents the progression of DCVC-initiated renal injury mediated by the calpain escaping out of damaged PTCs. Immunohistochemical detection of renal calpain and its activity in the urine, over a time course after treatment with the LD9 dose of DCVC, indicated progressive increase in leakage of calpain into the extracellular spaces of the injured PTCs of the non-diabetic (NDB) kidneys as compared to the DB kidneys. Calpastatin expression was minimally detected in the NDB kidneys, using immunohistochemistry, over the time course. On the other hand, consistently higher number of tubules in the DB kidney showed calpastatin expression over the time course. The lower leakage of calpain in the DB kidneys was commensurate with constitutively higher expression of calpastatin in the S-phase-laden PTCs of these mice. To test the protective role of newly divided/dividing PTCs, DB mice were given the anti-mitotic agent colchicine (CLC) (2 mg/kg and 1.5 mg/kg, i.p., on days 8 and 10 after STZ injection) prior to challenge with a LD9 dose of DCVC, which led to 100% mortality by 48 h. Mortality was due to rapid progression of DCVC-initiated renal injury, suggesting that newly divided/dividing cells are instrumental in mitigating the

  19. Inflammatory cascades driven by tumor necrosis factor-alpha play a major role in the progression of acute liver failure and its neurological complications.

    Directory of Open Access Journals (Sweden)

    Anne Chastre

    Full Text Available BACKGROUND/AIMS: Acute liver failure (ALF due to ischemic or toxic liver injury is a clinical condition that results from massive loss of hepatocytes and may lead to hepatic encephalopathy (HE, a serious neuropsychiatric complication. Although increased expression of tumor necrosis factor-alpha (TNF-α in liver, plasma and brain has been observed, conflicting results exist concerning its roles in drug-induced liver injury and on the progression of HE. The present study aimed to investigate the therapeutic value of etanercept, a TNF-α neutralizing molecule, on the progression of liver injury and HE in mice with ALF resulting from azoxymethane (AOM hepatotoxicity. METHODS/PRINCIPAL FINDINGS: Mice were administered saline or etanercept (10 mg/kg; i.p. 30 minutes prior to, or up to 6 h after AOM. Etanercept-treated ALF mice were sacrificed in parallel with vehicle-treated comatose ALF mice and controls. AOM induced severe hepatic necrosis, leading to HE, and etanercept administered prior or up to 3 h after AOM significantly delayed the onset of coma stages of HE. Etanercept pretreatment attenuated AOM-induced liver injury, as assessed by histological examination, plasma ammonia and transaminase levels, and by hepatic glutathione content. Peripheral inflammation was significantly reduced by etanercept as shown by decreased plasma IL-6 (4.1-fold; p<0.001 and CD40L levels (3.7-fold; p<0.001 compared to saline-treated ALF mice. Etanercept also decreased IL-6 levels in brain (1.2-fold; p<0.05, attenuated microglial activation (assessed by OX-42 immunoreactivity, and increased brain glutathione concentrations. CONCLUSIONS: These results indicate that systemic sequestration of TNF-α attenuates both peripheral and cerebral inflammation leading to delayed progression of liver disease and HE in mice with ALF due to toxic liver injury. These results suggest that etanercept may provide a novel therapeutic approach for the management of ALF patients awaiting

    Burkitt's lymphoma (BL) is an aggressive B-cell non-Hodgkin lymphoma that is found predominantly in children, with the highest incidence occurring in Africa. The sporadic form occurs in non-endemic areas and typically involves the ileo-caecum and the bowel, whereas orbital and paranasal sinus involvement is rare. Here, we present an unusual case of sporadic BL in a Caucasian male child with rapidly progressive painful proptosis of the right eye. Magnetic resonance imaging showed an oval-shaped, extraconal mass in the supero-lateral part of the right orbit that deformed and dislocated the eyeball antero-inferiorly. The patient underwent anterior orbitotomy, and a biopsy of the excised tissue revealed a starry-sky appearance characteristic of BL. Postoperative aggressive chemotherapy was initiated with a good response after one week. PMID:27006106

The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of “chyle” occurs rapidly, the patient may present with signs of peritonitis. Preoperative...

    Full Text Available The association of complement with the progression of acute T cell mediated rejection (ATCMR is not well understood. We investigated the production of complement components and the expression of complement regulatory proteins (Cregs in acute T-cell mediated rejection using rat and human renal allografts.We prepared rat allograft and syngeneic graft models of renal transplantation. The expression of Complement components and Cregs was assessed in the rat grafts using quantitative real-time PCR (qRT-PCR and immunofluorescent staining. We also administered anti-Crry and anti-CD59 antibodies to the rat allograft model. Further, we assessed the relationship between the expression of membrane cofactor protein (MCP by immunohistochemical staining in human renal grafts and their clinical course.qRT-PCR results showed that the expression of Cregs, CD59 and rodent-specific complement regulator complement receptor 1-related gene/protein-y (Crry, was diminished in the rat allograft model especially on day 5 after transplantation in comparison with the syngeneic model. In contrast, the expression of complement components and receptors: C3, C3a receptor, C5a receptor, Factor B, C9, C1q, was increased, but not the expression of C4 and C5, indicating a possible activation of the alternative pathway. When anti-Crry and anti-CD59 mAbs were administered to the allograft, the survival period for each group was shortened. In the human ATCMR cases, the group with higher MCP expression in the grafts showed improved serum creatinine levels after the ATCMR treatment as well as a better 5-year graft survival rate.We conclude that the expression of Cregs in allografts is connected with ATCMR. Our results suggest that controlling complement activation in renal grafts can be a new strategy for the treatment of ATCMR.

  5. The Role of M2 Macrophages in the Progression of Chronic Kidney Disease following Acute Kidney Injury.

    Myung-Gyu Kim

    Full Text Available Acute kidney injury (AKI is a major risk factor in the development of chronic kidney disease (CKD. However, the mechanisms linking AKI to CKD remain unclear. We examined the alteration of macrophage phenotypes during an extended recovery period following ischemia/reperfusion injury (IRI and determine their roles in the development of fibrosis.The left renal pedicle of mice was clamped for 40 min. To deplete monocyte/macrophage, liposome clodronate was injected or CD11b-DTR and CD11c-DTR transgenic mice were used.Throughout the phase of IRI recovery, M2-phenotype macrophages made up the predominant macrophage subset. On day 28, renal fibrosis was clearly shown with increased type IV collagen and TGF-β. The depletion of macrophages induced by the liposome clodronate injection improved renal fibrosis with a reduction of kidney IL-6, type IV collagen, and TGF-β levels. Additionally, the adoptive transfer of the M2c macrophages partially reversed the beneficial effect of macrophage depletion, whereas the adoptive transfer of the M1 macrophages did not. M2 macrophages isolated from the kidneys during the recovery phase expressed 2.5 fold higher levels of TGF-β than the M1 macrophages. The injection of the diphtheria toxin into CD11b or CD11c-DTR transgenic mice resulted in lesser depletion or no change in M2 macrophages and had little impact on renal fibrosis.Although M2 macrophages are known to be indispensible for short-term recovery, they are thought to be main culprit in the development of renal fibrosis following IRI.

    The prevalence of acute kidney injury (AKI) is increasing, with its definition, diagnosis and stage being updated. New biomarkers of AKI have become a hot study,but none can be applied clinically as a substitute of serum creatinine. Identificationearly intervention of risk factors are important lor AKI prevention. Management of AKI incluo.es treatment ol primary disease, prevention of multi-organ dysfunction,maintaining the balance of water,electrolytes,and acid-base,and appropriate renal replacement therapy. Early hemodialysis can improve the outcome of AKI. Hemodialysis is better than peritoneal dialysis in removal of small molecule substances and correction of acidosis. Peritoneal dialysis can be used in small children and patients with unstable hemodynamics. Continuous renal replacement therapy has been generally applied in AKI,which can be a complementation of intermittent hemodialysis,although current evidences do not support a higher dosage instead of the traditional prescription of CRRT. High dosage may be effective for several special diseases.%急性肾损伤(AKI)发病率逐年递增,其概念、诊断及分期日趋准确,寻找新的生物标志物的研究已成为热点,但仍无法完全替代血肌酐.AKI的预防在于早期发现并祛除危险因素;其治疗包括治疗原发病,防止多器官功能障碍,维持水、电解质、酸碱平衡以及肾脏替代治疗.早期透析可以改善患者预后,血液透析对小分子物质的清除及酸中毒的纠优于腹膜透析,小儿及血流动力学不稳定患者可选择腹膜透析.连续性肾脏替代治疗(CRRT)已被广泛应用于AKI的治疗,但其与间断性血液透析(IHD)互为补充,可随AKI的不同阶段和病情变化而转换,CRRT的治疗剂量仍然推荐传统剂量,对于某些特殊疾病高剂量CRRT可能有效.

    Breast feeding provides a lot of short and long-term benefits for the mother and the baby. It prevents the baby of gastrointestinal, urinary and respiratory infections, atopical conditions and assures long-term protection of cardiovascular and metabolic diseases. The breast feeding decreases the risk for the mother of ovary and breast carcinoma and creates a positive emotional bond between the mother and the baby Mother's milk is a species specific; its content is relatively stable regardless of mother's age race, way and place of living. Mother's milk is not sterile. There is a 10 year international trial held in Spanish and Finnish universities. It has identified and count all microorganisms in mother's milk (more than 700) and proved that their content and quantity varies according the age of the baby. Mother's milk is a source of lactobacillus for baby's intestines and most of them have probiotic potential. Lactobacillus fermentum Lc40 (hereditum) is isolated from mother's milk. It has a good viability in gastrointestinal system, high level of adhesion to intestinal epithelium cells, produces glutation--strong antioxidant, good antibacterial activity to entero-pathogens and potential of increasing the immunologic response. Clinical trials reveal that Lactobacillus fermentum plays important role to microflora balance of mother's milk in mastitis during lactation. Many trials estimating the efficiency of lactobacillus fermentum in prevention and treatment of acute and subacute mastitis have been carried out. The results of them open a new door in front of us in the treatment of these conditions--treatment with probiotics instead of antibiotics. PMID:27514147

    ón como el aseguramiento de la provisión de agua potable para el recién nacido.OBJECTIVE: To assess the effect of exclusive breastfeeding and its interactions with selected socioeconomic factors, on the incidence of acute infantile diarrhea during the first three months of life. MATERIAL AND METHODS: A prospective cohort study with a follow up of three months was conducted in 327 mother and child pairs, living in the city of Durango, Mexico, between April and June 1994. Data analyses included simple univariate and bivariate cross-tabulations, as well as multivariate logistic regression models with random effects. RESULTS: Infants who were not exclusively breastfed were at a significantly increased risk of having acute diarrhea during early infancy (ORcombined breastfeeding= 3.23; 95% CI 1.84-5.68 and ORartificial breastfeeding=4.36; 95% CI 2.32-8.19. Moreover, the protective effect of breastfeeding was independent from the effects of the following factors: poor maternal education, lack of social support for baby care, and being an adolescent mother. However, lack of potable water and lack of sewerage were potential effect modifiers of type of lactation deltaG=9.26; p=0.09; ORno water/no sewerage= 2.58; 95% CI 1.10-6.03 in the final multivariate model, for simultaneous lack of potable water and sewerage, which is greater than the sum of the individual OR for each variable. CONCLUSIONS: Similar to previous studies, exclusive breastfeeding was found to have great importance, since this practice protects the child's health and allows for a better development, despite unfavorable social and economic conditions. In particular, it seems that the protection conferred by breastfeeding is stronger when home conditions are poor, but this same condition presents an intervention opportunity, particularly the assurance of potable water provision for the infant when breastfeeding is not an option.

    Full Text Available Objective(s: T-cell acute lymphoblastic leukemia (T-ALL is an aggressive hematologic malignant tumor. Administration of chemical compounds influencing apoptosis and T cell development has been discussed as promising novel therapeutic strategies. Valproic acid (VPA as a recently emerged anti-neoplastic histone deacetylase (HDAC inhibitor and pioglitazone (PGZ as a high-affinity peroxisome proliferator-activated receptor-gamma (PPARγ agonist have been shown to induce apoptosis and cell cycle arrest in different studies. Here, we aimed to investigate the underlying molecular mechanisms involved in anti-proliferative effects of these compounds on human Jurkat cells. Materials and Methods: Treated cells were evaluated for cell cycle progression and apoptosis using flowcytometry and MTT viability assay. Real-time RT-PCR was carried out to measure the alterations in key genes associated with cell death and cell cycle arrest. Results: Our findings illustrated that both VPA and PGZ can inhibit Jurkat E6.1 cells in vitro after   24 hr; however, PGZ 400 μM presents the most anti-proliferative effect. Interestingly, treated cells have been arrested in G2/M with deregulated cell division cycle 25A (Cdc25A phosphatase and cyclin-dependent kinase inhibitor 1B (CDKN1B or p27 expression. Expression of cyclin D1 gene was inhibited when DNA synthesis entry was declined. Cell cycle deregulation in PGZ and VPA-exposed cells generated an increase in the proportion of aneuploid cell population, which has not reported before. Conclusion: These findings define that anti-proliferative effects of PGZ and VPA on Jurkat cell line are mediated by cell cycle deregulation. Thus, we suggest PGZ and VPA may relieve potential therapeutic application against apoptosis-resistant malignancies.

    Full Text Available Most fish farmers and ornamental fish hobbyists buy the bulk of their feed from commercial manufacturers. However, small quantities of specialized feeds are often needed for experimental purposes, feeding difficult-to maintain aquarium fishes, larval or small juvenile fishes, brood fish conditioning, or administering medication to sick fish. Small ornamental fish farms with an assortment of fish require small amounts of various diets with particular ingredients. It is not cost effective for commercial manufacturers to produce very small quantities of specialized feeds. Most feed mills will only produce custom formulations in quantities of more than one ton, and medicated feeds are usually sold in 50-pound bags. Small fish farmers, hobbyists and laboratory technicians are, therefore, left with the option of buying large quantities of expensive feed, which often goes to waste. Small quantities of fish feeds can be made quite easily in the laboratory, classroom, or at home, with common ingredients and simple kitchen or laboratory equipment. Hence, this review provides the knowledge about the fish feed formulation and feeding technology concerned with the live feed for fish larvae, fish feeds, fish feed ingredients, common fish feed stuffs, animal and plant sources of feeds for culture fish, and fish feeding methods.

    Myocarditis is defined as inflammation of the myocardium accompanied by myocellular necrosis. Acute myocarditis must be considered in patients who present with recent onset of cardiac failure or arrhythmia. Fulminant myocarditis is a distinct entity characterized by sudden onset of severe congestive heart failure or cardiogenic shock, usually following a flu-like illness, parvovirus B19, human herpesvirus 6, coxsackievirus and adenovirus being the most frequently viruses responsible for the disease. Treatment of myocarditis remains largely supportive, since immunosuppression has not been proven to be beneficial for acute lymphocytic myocarditis. Trials of antiviral therapies, or immunostimulants such as interferons, suggest a potential therapeutic role but require further investigation. Lastly, early recognition of patients rapidly progressing to refractory cardiac failure and their immediate transfer to a medical-surgical center experienced in mechanical circulatory support is warranted. In this setting, ECMO should be the first-line mechanical assistance. For highly unstable patients, a Mobile Cardiac Assistance Unit, that rapidly travels to primary care hospitals with a portable ECMO system and hooks it up before refractory multiorgan failure takes hold, is the preferred option.

    急性胰腺炎是一种常见的急性外科疾病,其重症患者发病率和死亡率较高。新的治疗指导方针最近由美国胃肠病学会和国际胰腺病学协会与美国胰腺协会联合出版发行。所有胰腺炎的患者均应该有其病史特征,包括实验室检查结果(肝功能检查、血清钙和甘油三酯水平)和经腹超声表现;而特发性胰腺炎应把超声内镜作为一线检查;胆源性胰腺炎并发胆管炎的患者应在24 h内行内镜逆行胰胆管造影;急性胰腺炎患者应积极静脉补液和禁食。在轻度胰腺炎中,当腹痛和恶心呕吐得到缓解,可早期开始经口腔营养;轻度胆源性胰腺炎患者可在住院期间行腹腔镜胆囊切除术;除了积极的静脉补液和禁食外,重症胰腺炎患者应在症状出现后48 h后开始营养支持(口服或鼻饲),应尽可能避免全胃肠外营养。%Acute pancreatitis is a common acute surgical condition associated with high morbidity and mortality in severe cases. New guidelines for management have recently been published by the American College of Gastroenterology and by the International Association of Pancreatology in collaboration with the American Pancreatic Association. All patients with pancreatitis should have its cause determined by features of the history, results of laboratory tests (liver function tests, serum calcium triglyceride levels) and findings on transabdominal ultrasound. Those with idiopathic pancreatitis should have endoscopic ultrasound as a first-line investigation. Patients with biliary pancreatitis and concurrent cholangitis should have endoscopic retrograde cholangiopancreatography within 24 hours of presentation. Acute pancreatitis should be managed with aggressive hydration with intravenous fluids and fasting. Oral feeding can be recommenced in mild pancreatitis once pain, nausea and vomiting have been resolved. Patients with mild biliary pancreatitis should have a

    Following the induction of ischemic or toxin-mediated acute kidney injury (AKI), cellular adaptations occur that ‘re-program’ how the kidney responds to future superimposed insults. This re-programming is not simply a short-lived phenomenon; rather it can persist for many weeks, implying that a state of ‘biologic memory’ has emerged. These changes can be both adaptive and maladaptive in nature and they can co-exist in time. A beneficial adaptation is the emergence of acquired cytoresistance, ...

    2-Methoxyestradiol(2-ME2)is an endogenous metabolite of 17β-estradiol(E2)with estrogen receptor-independent anti-cancer activity.The current study sought to deter mine the mechanism of anti-cancer activity of 2-ME2 in human acute T lymphoblastic leukemia CEM cells.Results showed that 2-ME2 markedly suppressed proliferation of CEM cells in a time-and dose-dependent manner.2-ME2-treated CEM cells underwent typical apoptotic changes.Exposure to 2-ME2 led to G2/M phase cell-cycle arrest,which preceded apoptosis characterized by the appearance of a sub-G1 cell population.In addition,cytosolic cytochrome c release,increased procaspase-9 and-3 expressions,poly(ADP-ribose)polymerase (PARP)cleavage,and induced expression of caspase-8 were detected,suggesting that both the intrinsic apoptotic pathway and extrinsic apoptotic pathway were involved in 2-ME2-induced apoptosis.Moreover,the expression level of p21 protein was upregulated,whereas Bcl-2 and dysfunctional p53 protein were downregulated,which also contributed to 2-ME2-induced apoptosis.Our findings revealed that 2-ME2 might be a potent natural candidate for chemotherapeutic treatment of human acute T lymphoblastic leukemia when the precise effects of 2-ME2 were investigated further in other T leukemia cell lines and in primary T-cell leukemias.

Several new laboratory markers of acute pancreatitis in children, which include procalcitonin, phospholipase A2, PankrinTM, trypsinogen activation peptide, carboxypeptidase B activation peptide, human pancreas-specific protein/procarboxypeptidase B, polymorphonuclear elastase, serum amyloid protein A, and as well as intercellular adhesion molecule- 1, have been found and applied in recent years .They can provide reliable judgment methods for early diagnosis and prediction of the severity of acute pancreatitis in children, but most of the new laboratory markers are rarely used in clinic because they are difficult to be detected and expensive. More sensitive, specific, cheap and operable laboratory markers which can be used in clinic are to be explored.

    This study was conducted to evaluate the effects of Zingiber officinale Roscoe (Ginger), Arabic gum (AG), and Boswellia on both acute and chronic renal failure (CRF) and the mechanisms underlying their effects. Acute renal failure was induced by 30 min ischemia followed by 24 h reperfusion, while CRF was induced by adenine feeding for 8 weeks. Prophylactic oral administration of ginger, AG, Boswellia, or vehicle (in control groups) was started 3 days before and along with adenine feeding in different groups or 7 days before ischemia-reperfusion. Ginger and AG showed renoprotective effects in both models of renal failure. These protective effects may be attributed at least in part to their anti-inflammatory properties as evident by attenuating serum C-reactive protein levels and antioxidant effects as evident by attenuating lipid peroxidation marker, malondialdehyde levels, and increasing renal superoxide dismutase activity. Ginger was more potent than AG in both models of renal failure. However, Boswellia showed only partial protective effect against both acute renal failure and CRF and it had no antioxidant effects. Finally, we can say that ginger and AG could be beneficial adjuvant therapy in patients with acute renal failure and CRF to prevent disease progression and delay the need for renal replacement therapy.

    We conducted a longitudinal analysis of 117 lymphedema patients in a filariasis-endemic area of Haiti during 1995-2008. No difference in lymphedema progression between those who received or did not receive mass drug administration (MDA) was found on measures of foot (P = 0.24), ankle (P = 0.87), or leg (P = 0.46) circumference; leg volume displacement (P = 0.09), lymphedema stage (P = 0.93), or frequency of adenolymphangitis (ADL) episodes (P = 0.57). Rates of ADL per year were greater after initiation of MDA among both groups (P < 0.01). Nevertheless, patients who received MDA reported improvement in four areas of lymphedema-related quality of life (P ≤ 0.01). Decreases in foot and ankle circumference and ADL episodes were observed during the 1995-1998 lymphedema management study (P ≤ 0.01). This study represents the first longitudinal, quantitative, leg-specific analysis examining the clinical effect of diethylcarbamazine on lymphedema progression and ADL episodes.

    Primary HIV-1 infection (PHI) includes acute HIV-1 infection (AHI)and early HIV-1 infection (EHI). AHI is often associated with an acute "retroviral syndrome" that usually includes fever with a variety of nonspecific clinical and laboratory abnormalities. Critical point of AHI and EHI is HIV-1 antibody seroconversion. Cut-off point of PHI and following chronic phage is whether HIV-1 RNA decrease to the set point. Early diagnosis depends on HIV RNA and P24 antigen tests. About 50% of new sexual transmission happens while a person is in this primary phase of infection. HIV pandemic could be slowed down by early diagnosis and immediate antiretroviral therapy intervention. Several studies have suggested that treatment of AHI allows long-term viral suppression and might lead to preservation and even increase of HIV-1 specific T helper cell responses. However, there are no sufficient data available to support the clinical benefit of early initiation of antiretroviral therapy and to address the risks of antiretroviral therapy and treatment interruptions.%原发Ⅰ型艾滋病病毒(HIV-1)感染(PHI)包括急性期感染(AHI)和早期感染(EHI).AHI通常与急性的"反转录病毒综合征"有关,包括一系列非特异的症状和实验室检测异常.AHI和EHI的分界点在于HIV抗体的阳转,而PHI和其后的慢性感染阶段的临界点在于体内何时达到HIV-1的调定点.早期诊断有赖于检测HIV-1RNA和P24抗原.大约50%经性传染HIV发生在急性期阶段,对急性期/早期感染者尽早诊断并给予抗病毒治疗,能明显减少HIV的传播.一些研究显示,早期抗病毒治疗能够使病毒得以长期抑制,并能保持甚至增加HIV-1特异性T细胞免疫应答,但早期治疗和治疗中断的临床益处还没有足够数据支持.

    2011-01-01

    Full Text Available A number of issues have weakened the public's confidence in the quality and wholesomeness of foods of animal origin. As a result farmers, nutritionists, industry and governments have been forced to pay serious attention to animal feedstuff production processes, thereby acknowledging that animal feed safety is an essential prerequisite for human food safety. Concerns about these issues have produced a number of important effects including the ban on the use of processed animal proteins, the ban on the addition of most antimicrobials to farm animals diets for growth‐promotion purposes, and the implementation of feed contaminant regulations in the EU. In this context it is essential to integrate knowledge on feed safety and feed supply. Consequently, purchase of new and more economic sources of energy and protein in animal diets, which is expected to conform to adequate quality, traceability, environmental sustainability and safety standards, is an emerging issue in livestock production system.

    The harmful effects of particulate matter with an aerodynamic diameter of PM2.5) and its association with acute coronary syndrome (ACS) has gained increased attention in recent years. Significant associations between PM2.5 and ACS have been found in most studies, although sometimes only observed in specific subgroups. PM2.5-induced detrimental effects and ACS arise through multiple mechanisms, including endothelial injury, an enhanced inflammatory response, oxidative stress, autonomic dysfunction, and mitochondria damage as well as genotoxic effects. These effects can lead to a series of physiopathological changes including coronary artery atherosclerosis, hypertension, an imbalance between energy supply and demand to heart tissue, and a systemic hypercoagulable state. Effective strategies to prevent the harmful effects of PM2.5 include reducing pollution sources of PM2.5 and population exposure to PM2.5, and governments and organizations publicizing the harmful effects of PM2.5 and establishing air quality standards for PM2.5. PM2.5 exposure is a significant risk factor for ACS, and effective strategies with which to prevent both susceptible and healthy populations from an increased risk for ACS have important clinical significance in the prevention and treatment of ACS.

    Full Text Available The harmful effects of particulate matter with an aerodynamic diameter of <2.5 µm (PM2.5 and its association with acute coronary syndrome (ACS has gained increased attention in recent years. Significant associations between PM2.5 and ACS have been found in most studies, although sometimes only observed in specific subgroups. PM2.5-induced detrimental effects and ACS arise through multiple mechanisms, including endothelial injury, an enhanced inflammatory response, oxidative stress, autonomic dysfunction, and mitochondria damage as well as genotoxic effects. These effects can lead to a series of physiopathological changes including coronary artery atherosclerosis, hypertension, an imbalance between energy supply and demand to heart tissue, and a systemic hypercoagulable state. Effective strategies to prevent the harmful effects of PM2.5 include reducing pollution sources of PM2.5 and population exposure to PM2.5, and governments and organizations publicizing the harmful effects of PM2.5 and establishing air quality standards for PM2.5. PM2.5 exposure is a significant risk factor for ACS, and effective strategies with which to prevent both susceptible and healthy populations from an increased risk for ACS have important clinical significance in the prevention and treatment of ACS.

  19. Viral Dose and Immunosuppression Modulate the Progression of Acute BVDV-1 Infection in Calves: Evidence of Long Term Persistence after Intra-Nasal Infection.

    Directory of Open Access Journals (Sweden)

    Rebecca Strong

    Full Text Available Bovine viral diarrhoea virus (BVDV infection of cattle causes a diverse range of clinical outcomes from being asymptomatic, or a transient mild disease, to producing severe cases of acute disease leading to death. Four groups of calves were challenged with a type 1 BVDV strain, originating from a severe outbreak of BVDV in England, to study the effect of viral dose and immunosuppression on the viral replication and transmission of BVDV. Three groups received increasing amounts of virus: Group A received 10(2.55TCID50/ml, group B 10(5.25TCID50/ml and group C 10(6.7TCID 50/ml. A fourth group (D was inoculated with a medium dose (10(5.25TCID50/ml and concomitantly treated with dexamethasone (DMS to assess the effects of chemically induced immunosuppression. Naïve calves were added as sentinel animals to assess virus transmission. The outcome of infection was dose dependent with animals given a higher dose developing severe disease and more pronounced viral replication. Despite virus being shed by the low-dose infection group, BVD was not transmitted to sentinel calves. Administration of dexamethasone (DMS resulted in more severe clinical signs, prolonged viraemia and virus shedding. Using PCR techniques, viral RNA was detected in blood, several weeks after the limit of infectious virus recovery. Finally, a recently developed strand-specific RT-PCR detected negative strand viral RNA, indicative of actively replicating virus, in blood samples from convalescent animals, as late as 85 days post inoculation. This detection of long term replicating virus may indicate the way in which the virus persists and/or is reintroduced within herds.

    Cocaine induces fast dopamine increases in brain striatal regions, which are recognized to underlie its rewarding effects. Both dopamine D1 and D2 receptors are involved in cocaine's reward but the dynamic downstream consequences of cocaine effects in striatum are not fully understood. Here we used transgenic mice expressing EGFP under the control of either the D1 receptor (D1R) or the D2 receptor (D2R) gene and microprobe optical imaging to assess the dynamic changes in intracellular calcium ([Ca{sup 2+}]{sub i} ) responses (used as marker of neuronal activation) to acute cocaine in vivo separately for D1R- versus D2R-expressing neurons in striatum. Acute cocaine (8 mg/kg, i.p.) rapidly increased [Ca{sup 2+}]{sub i} in D1R-expressing neurons (10.6 {+-} 3.2%) in striatum within 8.3 {+-} 2.3 min after cocaine administration after which the increases plateaued; these fast [Ca{sup 2+}]{sub i} increases were blocked by pretreatment with a D1R antagonist (SCH23390). In contrast, cocaine induced progressive decreases in [Ca{sup 2+}]{sub i} in D2R-expressing neurons (10.4 {+-} 5.8%) continuously throughout the 30 min that followed cocaine administration; these slower [Ca{sup 2+}]{sub i} decreases were blocked by pretreatment with a D2R antagonist (raclopride). Since activation of striatal D1R-expressing neurons (direct-pathway) enhances cocaine reward, whereas activation of D2R expressing neurons suppresses it (indirect-pathway) (Lobo et al., 2010), this suggests that cocaine's rewarding effects entail both its fast stimulation ofD1R (resulting in abrupt activation of direct-pathway neurons) and a slower stimulation of D2R (resulting in longer-lasting deactivation of indirect-pathway neurons). We also provide direct in vivo evidence of D2R and D1R interactions in the striatal responses to acute cocaine administration.

  3. Is gastric sham feeding really sham feeding?

    Science.gov (United States)

    Sclafani, A; Nissenbaum, J W

    1985-03-01

    Rats were fitted with gastric cannulas, food deprived, and allowed to drink a sugar solution that drained out of the opened cannula; i.e., the rats sham-fed. Although this procedure is thought to prevent absorption of ingested food, it was found that the sham feeding of a 32% glucose or sucrose solution significantly elevated blood glucose levels. The addition of acarbose, a drug that inhibits the digestion of sucrose, to the 32% sucrose solution blocked the blood glucose rise, as did closing the pylorus with an inflatable pyloric cuff. Neither the drug nor the cuff, however, reduced the amount of sucrose solution consumed. These findings indicate that gastric sham feeding does not necessarily prevent the digestion and absorption of food, although absorption is not essential for the appearance of a vigorous sham-feeding response. Nevertheless the possibility that neural or hormonal feedback from the stomach contributes to the sham-feeding response cannot be excluded, and until this issue is resolved the results of gastric sham-feeding studies should be interpreted with caution.

    The recently published guidelines for acute pancreatitis (AP) suggest that enteral nutrition (EN) should be the primary therapy in patients suffering from severe acute pancreatitis (SAP); however, none of the guidelines have recommendations on mild and moderate AP (MAP). A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The following PICO (problem, intervention, comparison, outcome) was applied: P: nutrition in AP; I: enteral nutrition (EN); C: nil per os diet (NPO); and O: outcome. There were 717 articles found in Embase, 831 in PubMed, and 10 in the Cochrane database. Altogether, seven SAP and six MAP articles were suitable for analyses. In SAP, forest plots were used to illustrate three primary endpoints (mortality, multiorgan failure, and intervention). In MAP, 14 additional secondary endpoints were analyzed (such as CRP (C-reactive protein), WCC (white cell count), complications, etc.). After pooling the data, the Mann–Whitney U test was used to detect significant differences. Funnel plots were created for testing heterogeneity. All of the primary endpoints investigated showed that EN is beneficial vs. NPO in SAP. In MAP, all of the six articles found merit in EN. Analyses of the primary endpoints did not show significant differences between the groups; however, analyzing the 17 endpoints together showed a significant difference in favor of EN vs. NPO. EN is beneficial compared to a nil per os diet not only in severe, but also in mild and moderate AP. PMID:27775609

    VLBI2010 requires a feed that simultaneously has high efficiency over the full 2.2-14 GHz frequency range. The simultaneity requirement implies that the feed must operate at high efficiency over the full frequency range without the need to adjust its focal position to account for frequency dependent phase centre variations. Two feeds meet this specification: The Eleven Feed developed at Chalmers University. (For more information, contact Miroslav Pantaleev, miroslav.pantaleev@chalmers.se. The Eleven Feed, integrated with LNA's in a cryogenic receiver, is available as a product from Omnisys Instruments, info@omnisys.se). The Quadruple Ridged Flared Horn (QRFH) developed at the California Institute of Technology. (For more information please contact Ahmed Akgiray, aakgiray@ieee.org or Sander Weinreb, sweinreb@caltech.edu) Although not VLBI2010 compliant, two triband S/X/Ka feeds are also being developed for the commissioning of VLBI2010 antennas, for S/X observations during the VLBI2010 transition period, and to support X/Ka CRF observations. The two feeds are: The Twin Telescopes Wettzell (TTW) triband feed developed by Mirad Microwave.

    Acute interstitial pneumonia (AIP) of feedlot cattle is a sporadically occurring respiratory condition that is often fatal. Affected cattle have a sudden onset of labored breathing. There is no confirmed effective treatment of feedlot AIP; however, administration of antibiotics effective against common bacterial respiratory pathogens and nonsteroidal anti-inflammatory drugs, especially aspirin, has been recommended. Protective strategies are not well defined, but efforts to limit dust exposure and heat stress; to ensure consistent formulation, mixing, and delivery of feed; and to identify and treat infectious respiratory disease in a timely manner may decrease rates of feedlot AIP.

    Acute myelogenous leukemia (AML) can involve the gastrointestinal tract but rarely involves the appendix.We report a male patient who had 1 year partial remission from AML and who presented with apparent acute appendicitis as the initial manifestation of leukemia relapse. Pathological findings of the appendix revealed transmural infiltrates of myeloblasts, whichindicated a diagnosis of leukemia. Unfortunately, the patient died from progression of the disease on the 19th d after admission. Although leukemic cell infiltration of the appendix is uncommon, patients with leukemia relapse can present with symptoms mimicking acute appendicitis.

  15. Urban Bird Feeding: Connecting People with Nature

    2016-01-01

    At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples’ relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.

    becomes catabolic due to the high priority of milk production and to current feeding practices. Indeed, feed is changed from a gestation to a lactation diet for most sows and the feed supply typically goes from a restricted supply to an ad libitum allowance. In addition, transition sows are often exposed...... the first few days of lactation, and milk yield increases throughout the transition period and becomes the most important determinant of nutrient requirements. Thus, nutrient requirements of transition sows are affected by many intrinsic factors and these requirements change rapidly, yet, sow feeding...... practices do not acknowledge these changes. Development of new feeding strategies specifically adapted for the transition sow is likely of importance to match the rapid changes in nutrient requirements....

    Full Text Available The management of acute pancreatitis differs according to its severity. Approximately 75% of patients with acute pancreatitis have mild disease with a mortality rate below 1%. Mortality increases up to 20% if the disease progresses to its severe necrotizing form and, in the most severe cases, mortality can increase to 30-40%. Severe acute pancreatitis is usually accompanied by systemic inflammatory response syndrome (SIRS which results in hypermetabolism with prominent protein catabolism. Acute malnutrition, commonly observed in patients with acute pancreatitis, is associated with immunological disturbances, septic complications and delayed healing of surgical wounds, and may lead to multiorgan dysfunction or failure syndrome (MODS or MOFS and increased morbidity and mortality [1].

    This is a report of an in vitro study evaluating the ability of six solutions to dissolve clotted enteral feeding, which can cause feeding tube occlusion. The following clotted enteral feeding products were tested: Ensure Plus, Ensure Plus with added protein (Promod 20 g/liter), Osmolite, Enrich, and Pulmocare. Clot dissolution was then tested by adding Adolf's Meat Tenderizer, Viokase, Sprite, Pepsi, Coke, or Mountain Dew. Distilled water served as control. Dissolution score for each mixture was assessed blindly. Best dissolution was observed with Viokase in pH 7.9 solution (p less than 0.01). Similar results were obtained when feeding tube patency was restored in eight in vitro occluded feeding tubes (Dobbhoff, French size 8) by using first Pepsi (two/eight successful) and then Viokase in pH 7.9 (six/six successful). We also report our experience in the first 10 patients with occluded feeding tubes using this Viokase solution injected through a Drum catheter into the feeding tube. In seven patients, this method proved to be successful, and the reasons for failure in three patients include a knotted tube, impacted tablet powder, and a formula clot fo 24 hr duration and 45 cm in length.

This may be because the occurrence and progression of AP, which involves various inflammatory cells and cytokines, includes a series of complex immune events. Considering the complex immune system alterations during the course of AP, it is necessary to monitor the indicators related to immune cells...

    Objective To study the effects of mosapride and domperidone on the pulmonary infection of acute stroke patients lying in bed and with nasal feeding. Methods Eighty-nine acute stroke patients lying in bed and with nasal feeding were divided randomly into the treatment group (47 cases) and the control group (42 cases). The control group was treated routinely,and the treatment group was treated with mosapride 5 mg and domporidone 20 mg thrice a day for 4 weeks, besides routine therapy. The incidence rate of pulmonary infection, gastric residual volume (GRV) and the number of cases with gastric contents remaining after 3 hours of nasal feeding were studied. All data were analyzed statistically. Results In the treatment group, 13 cases had pulmonary infection,and the incidence rate was 27.66%(13/47). In the control group,25 cases had pulmonary infection,and the incidence rate was 59.52% (25/42). There was significant difference between the two groups (P < 0.01 ). Three hours after nasal feeding,24 cases with gastric contents remaining were discovered in the treatment group,and GRV was (50.80±15.38) ml. Two hundred and thirty-seven cases with gastric contents remaining were discovered in the control group, and GRV was (112.17±32.54) ml. Significance differences were also detected between the two groups (P<0.01). Conclusion As for the acute stroke patients lying in bed and with nasal feeding,mosapride and domperidone can remarkably cut down the pulmonary infection upon common treatment.%目的 观察莫沙必利和多潘立酮对卧床、鼻饲的急性脑卒中患者医院内肺部感染发生率的影响.方法 89例卧床、鼻饲的急性脑卒中患者,采用随机数字表法分为研究组(47例)和对照组(42例),两组均给予脑卒中常规治疗,研究组在此基础上服用莫沙必利5 mg,多潘立酮20 mg,每日3次,连续4周.观察住院4周内两组患者肺部感染发生率及鼻饲后3 h胃内容物残留例次及残留量,

  16. Rhopalosiphum padi Feeding � Attempted Symptomatic Defence Mechanisms in Barley Leaves Include Wound Callose Deposition?

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available The deposition of callose and the damage-related symptoms subsequently expressed by infested plants were investigated after feeding on barley leaves by bird cherry-oat aphid (BCA, Rhopalosiphum padi L. Feeding by this aphid does not result in appearance of visible damage to the plants, provided the feeding population is small. Using aniline blue fluorochrome, we confirmed that whilst low feeding density (5 aphids results in appearance of wound callose in sieve tubes, this only occurs after 14d of feeding, when the feeding population had increased. Continued feeding results in progressively more callose deposition and by 21d, severe damage has been caused. In contrast, feeding by larger populations (50 adult aphids, results in the appearance of wound callose within 72h, in longitudinal and cross veins. We suggest that this wounding response appears to play a role in the appearance of golden yellow streak symptoms reported to occur in leaves where BCA feeding density was high.

    International Nuclear Information System (INIS)

    Cannabis is a drug derived from hemp plant, Cannabis sativa, used both as a recreational drug or as medicine. It is a widespread illegal substance, generally smoked for its hallucinogenic properties. Little is known about the adverse effects of postnatal cannabis exposure throw breast feeding because of a lack of studies in lactating women. The active substance of cannabis is the delta 9 Tetrahydrocannabinol (THC). Some studies conclude that it could decrease motor development of the child at one year of age. Therefore, cannabis use and abuse of other drugs like alcohol, tobacco, or cocaine must be contraindicated during breast feeding. Mothers who use cannabis must stop breast feeding, or ask for medical assistance to stop cannabis use in order to provide her baby with all the benefits of human milk.

    疗SAP,能明显缩短患者的临床症状缓解时间,减少并发症,降低患者的死亡率;SAP的发生发展可能与凋亡相关蛋白质有关.%AIM: To investigate the relationship between the development and progression of severe acute pancreatitis (SAP) and apoptosis-related proteins in rats. METHODS: Sixty SD rats were randomly divided into two groups: acute necrotizing pancreatitis (ANP) group and sham-operated (SO) group (n = 30 for each). At 3,6, and 12 h after induction of ANP, the rats were sacrificed and blood samples were collected from the inferior vena cava. Density gradient centrifugation was conducted to separate polymorpho nuclear neutrophils (PMNs), and PMN apoptosis was determined by flow cytometry. PMNs collected at 12 h were lysed, and label-free technology was used to identify apoptosis-related proteins. Twenty-eight SAP patients treated at our hospital from June 2008 to June 2012 were randomly divided into a treatment group and a control group (n = 14 for each). The control group underwent conventional treatment, while the treatment group was treated with conventional treatment plus continuous infusion of somatostatin. The mean duration of abdominal pain, amylase recovery time, length of hospital stay, and the incidence of complications, rate of conversion to surgery, and mortality were compared between the two groups. RESULTS: PMN apoptosis was significantly delayed in the ANP group compared to the SO group at all time points (all P < 0.01). Four PMN apoptosis-related proteins were identified: 78 Kda glucose-regulated protein, RhoGTPase, L-lactic acid dehydrogenase A chain, and hemoglobin a2 chain (ANP/SO ratios: 1.953614, 3.526625, 1.766764, 0.609825; all P < 0.05). The mean duration of abdominal pain, amylase recovery time and length of stay were significantly shorter (P = 0.041, 0.001, 0.000), and the incidence of complications, rate of conversion to surgery, and mortality were significantly lower in the treatment group than in the

    Hypothalamic pro-opiomelanocortin (POMC) neurons promote satiety. Cannabinoid receptor 1 (CB1R) is critical for the central regulation of food intake. Here we test whether CB1R-controlled feeding in sated mice is paralleled by decreased activity of POMC neurons. We show that chemical promotion of CB1R activity increases feeding, and notably, CB1R activation also promotes neuronal activity of POMC cells. This paradoxical increase in POMC activity was crucial for CB1R-induced feeding, because designer-receptors-exclusively-activated-by-designer-drugs (DREADD)-mediated inhibition of POMC neurons diminishes, whereas DREADD-mediated activation of POMC neurons enhances CB1R-driven feeding. The Pomc gene encodes both the anorexigenic peptide α-melanocyte-stimulating hormone, and the opioid peptide β-endorphin. CB1R activation selectively increases β-endorphin but not α-melanocyte-stimulating hormone release in the hypothalamus, and systemic or hypothalamic administration of the opioid receptor antagonist naloxone blocks acute CB1R-induced feeding. These processes involve mitochondrial adaptations that, when blocked, abolish CB1R-induced cellular responses and feeding. Together, these results uncover a previously unsuspected role of POMC neurons in the promotion of feeding by cannabinoids. PMID:25707796

  6. Nutritional support for acute pancreatitis.

    1992-09-01

    The current review has summarized current data relevant to the nutritional support of patients with acute pancreatitis. Selection of the most appropriate form of nutritional support for patients with acute pancreatitis is intimately linked to a thorough understanding of the effects of various forms of enteral and parenteral nutrition on physiologic exocrine secretory mechanisms. Two basic concepts have emerged from the multiple studies that have addressed these issues to date: 1, enteral feeds should have low fat composition and be delivered distal to the ligament of Treitz to minimize exocrine pancreatic secretion and 2, parenteral substrate infusions, alone or in combinations similar to those administered during TPN, do not stimulate exocrine pancreatic secretion. From a practical standpoint, most patients with acute pancreatitis are diagnosed by nonoperative means and will manifest some degree of paralytic ileus during the early phase of the disease. Therefore, jejunal feeds are usually not a therapeutic option early in the course of this disease. On the basis of the clinical studies reviewed herein we propose general guidelines for the nutritional support of patients with acute pancreatitis: 1, most patients with mild uncomplicated pancreatitis (one to two prognostic signs) do not benefit from nutritional support; 2, nutritional support should begin early in the course of patients with moderate to severe disease (as soon as hemodynamic and cardiorespiratory stability permit); 3, initial nutritional support should be through the parenteral route and include fat emulsion in amounts sufficient to prevent essential fatty acid deficiency (no objective data exist to recommend specific amino acid formulations); 4, patients requiring operation for diagnosis or complications of the disease should have a feeding jejunostomy placed at the time of operation for subsequent enteral nutrition using a low fat formula, such as Precision HN (Sandoz, 1.3 percent calories as fat

    This is a report of an in vitro study evaluating clotting ability of some formulas with intact protein and hydrolyzed protein sources in a series of buffers ranging from a pH of 1 thru 10. The following 10 products were tested: Ensure Plus, Ensure, Enrich, Osmolite, Pulmocare, Citrotein, Resource, Vivonex TEN, Vital, and Hepatic Acid II. Protein (10 and 20 g/liter) was added to Citrotein and Ensure Plus. All formulas were tested at full and some at half strength. Clotting occurred only in premixed intact protein formulas (Pulmocare, Ensure Plus, Osmolite, Enrich, Ensure) and in Resource. No clotting was observed for Citrotein (intact protein formula in powder form), Vital, Vivonex TEN, and Hepatic Aid II. Adding protein did not cause or increase clotting. In summary, clotting of some liquid formula diet appears to be an important factor causing possible gastric feeding tube occlusion. The following measures may help in preventing this problem: flushing before and after aspirating for gastric residuals to eliminate acid precipitation of formula in the feeding tube, advance the nasogastric feeding tube into the duodenum if possible, and avoid mixing these products with liquid medications having a pH value of 5.0 or less.

    To present a summary of current knowledge regarding acute kanamycin sulfate-induced deafness in guinea pig, by reviewing the published literature. Animal model of acute deafness induced by a single dose of kanamycin sulfate in combination with ethacrynic acid or furosemide in guinea pig was usually used to investigate the mechanism of cochlear cell degeneration. There were different time sequences of cell degeneration of spiral ganglion cell and hair cell in different studies. The findings may result from different doses, order of two drugs administration or rime point chosen. There remains scope for further research in chronic kanamycin-induced deafness, which more replicates the type of exposure to people than acute deafness.

    In this paper, we investigate effect of changing the connection of feed-forward loop based on error signal. Our motivation of this work is solution to progress of human skill. For the skill model, we study a human simple action such as arm motion. Many models that describe the human arm dynamics have been proposed in recent year. While one type does not need an inverse model of human dynamics, the system based on the model does not include feed-forward loop. On the other hand, another type model has a feed-forward loop and feedback loop systems. This type assumes feed-forward element includes an internal model by repeating action or training and this loop progress our skill. Then we usually have to exercise to get a good performance. This says that we design the internal motion model by training and we move on prediction for motion. Under the assumption, Kawato model is well known. The model proposed that learning of feed-forward element is promoted in brain so that the error of feedback loop decreases. Furthermore, we assume the connections in feedback loop and feed-forward loop are changed. We show numerical simulations and consider that the position error given by our vision changes the skill element and we confirm that the position error is the one of the estimate function for the improvement in our skill.

  1. Perinatal programming of neuroendocrine mechanisms connecting feeding behavior and stress

    Full Text Available Feeding behavior is closely regulated by neuroendocrine mechanisms that can be influenced by stressful life events. However, the feeding response to stress varies among individuals with some increasing and others decreasing food intake after stress. In addition to the impact of acute lifestyle and genetic backgrounds, the early life environment can have a life-long influence on neuroendocrine mechanisms connecting stress to feeding behavior and may partially explain these opposing feeding responses to stress. In this review I will discuss the perinatal programming of adult hypothalamic stress and feeding circuitry. Specifically I will address how early life (prenatal and postnatal nutrition, early life stress, and the early life hormonal profile can program the hypothalamic-pituitary-adrenal (HPA axis, the endocrine arm of the body’s response to stress long-term and how these changes can, in turn, influence the hypothalamic circuitry responsible for regulating feeding behavior. Thus, over- or under-feeding and / or stressful events during critical windows of early development can alter glucocorticoid (GC regulation of the HPA axis, leading to changes in the GC influence on energy storage and changes in GC negative feedback on HPA axis-derived satiety signals such as corticotropin-releasing-hormone. Furthermore, peripheral hormones controlling satiety, such as leptin and insulin are altered by early life events, and can be influenced, in early life and adulthood, by stress. Importantly, these neuroendocrine signals act as trophic factors during development to stimulate connectivity throughout the hypothalamus. The interplay between these neuroendocrine signals, the perinatal environment, and activation of the stress circuitry in adulthood thus strongly influences feeding behavior and may explain why individuals have unique feeding responses to similar stressors.

  3. Radiation pasteurization of poultry feed: Preliminary results of feeding tests

    International Nuclear Information System (INIS)

    Feed used to rear farm animals for human consumption has often been implicated as a vehicle for dissemination of microbial pathogens that can adversely affect both animals or birds, and humans. Radiation pasteurization of animal feed to improve its microbiological quality should reduce the incidence of feed-borne infection in the herd or flock. This would result in safer food for the consumer, and improved economic performance of the production unit. This latter benefit is particularly important because it would directly offset the cost of treating the feed. The likelihood of occurrence, as well as the magnitude, of any improved economic performance in the herd or flock consuming the irradiated feed must be determined experimentally. Accordingly, short term feeding tests were carried out to determine the effect of radiation pasteurization of poultry feed on growth performance of young chicks. The results suggest that radiation pasteurization of poultry feed may have a beneficial effect on the feed conversion efficiency of the birds consuming that feed. 10 refs, 8 tabs

    2011-01-01

    Acute viral bronchiolitis represents the most common lower respiratory tract infection in infants and young children and is associated with substantial morbidity and mortality. Respiratory syncytial virus is the most frequently identified virus, but many other viruses may also cause acute bronchiolitis. There is no common definition of acute viral bronchiolitis used internationally, and this may explain part of the confusion in the literature. Most children with bronchiolitis have a self limiting mild disease and can be safely managed at home with careful attention to feeding and respiratory status. Criteria for referral and admission vary between hospitals as do clinical practice in the management of acute viral bronchiolitis, and there is confusion and lack of evidence over the best treatment for this condition. Supportive care, including administration of oxygen and fluids, is the cornerstone of current treatment. The majority of infants and children with bronchiolitis do not require specific measures. Bronchodilators should not be routinely used in the management of acute viral bronchiolitis, but may be effective in some patients. Most of the commonly used management modalities have not been shown to have a clear beneficial effect on the course of the disease. For example, inhaled and systemic corticosteroids, leukotriene receptor antagonists, immunoglobulins and monoclonal antibodies, antibiotics, antiviral therapy, and chest physiotherapy should not be used routinely in the management of bronchiolitis. The potential effect of hypertonic saline on the course of the acute disease is promising, but further studies are required. In critically ill children with bronchiolitis, today there is little justification for the use of surfactant and heliox. Nasal continuous positive airway pressure may be beneficial in children with severe bronchiolitis but a large trial is needed to determine its value. Finally, very little is known on the effect of the various

    The effect of a therapeutically administered high calorie diet in a severely malnourished patient is discussed in this case report. In patients with advanced head and neck cancer prolonged periods of malnutrition prior to admission are frequently encountered. This case report highlights the need to constantly monitor the electrolyte and vitamin levels during the early stages of instituting enteral or parenteral nutrition. By vigilant monitoring and a high index of suspicion re-feeding syndrome or severe hypophosphataemia and its associated complications can be avoided.

    2013-03-01

    Full Text Available Oxytocin neurones have a physiological role in food intake and energy balance. Central administration of oxytocin is powerfully anorexigenic, reducing food intake and meal duration. The central mechanisms underlying this effect of oxytocin have become better understood in the past few years. Parvocellular neurones of the paraventricular nucleus project to the caudal brainstem to regulate feeding via autonomic functions including the gastrointestinal vago-vagal reflex. In contrast, magnocellular neurones of the supraoptic and paraventricular nuclei release oxytocin from their dendrites to diffuse to distant hypothalamic targets involved in satiety.The ventromedial hypothalamus, for example, expresses a high density of oxytocin receptors but does not contain detectable oxytocin nerve fibres. Magnocellular neurones represent targets for the anorexigenic neuropeptide α-melanocyte stimulating hormone. . In addition to homeostatic control, oxytocin may also have a role in reward-related feeding. Evidence suggests that oxytocin can selectively suppress sugar intake and that it may have a role in limiting the intake of palatable food by inhibiting the reward pathway.

    The Advanced Liquid Feed Experiment (ALFE) is a Hitchhiker experiment flown on board the Shuttle of STS-39 as part of the Space Test Payload-1 (STP-1). The purpose of ALFE is to evaluate new propellant management components and operations under the low gravity flight environment of the Space Shuttle for eventual use in an advanced spacecraft feed system. These components and operations include an electronic pressure regulator, an ultrasonic flowmeter, an ultrasonic point sensor gage, and on-orbit refill of an auxiliary propellant tank. The tests are performed with two transparent tanks with dyed Freon 113, observed by a camera and controlled by ground commands and an on-board computer. Results show that the electronic pressure regulator provides smooth pressure ramp-up, sustained pressure control, and the flexibility to change pressure settings in flight. The ultrasonic flowmeter accurately measures flow and detects gas ingestion. The ultrasonic point sensors function well in space, but not as a gage during sustained low-gravity conditions, as they, like other point gages, are subject to the uncertainties of propellant geometry in a given tank. Propellant transfer operations can be performed with liquid-free ullage equalization at a 20 percent fill level, gas-free liquid transfer from 20-65 percent fill level, minimal slosh, and can be automated.

    2008-01-01

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    2014-03-01

    Full Text Available Acute biliary pancreatitis is one of the major causes of acute pancreatitis.Gallstones, biliary sludge and microlithiasis, especially in pancreatitis without detectable reason, can be the cause of acute pancreatitis. Acute biliary pancreatitis has many controversions in the literature, and its classification and guidelines are being updated very frequently. Atlanta classifications which determine the definitions and guidelines about acute pancreatitis were renewed and published in 2013. It has various clinical aspects, ranging from a mild form which is easily treated, to a severe form that causes complications leading to mortality. The pathogenesis of this disease has not been fully elucidated and several theories have been suggested. New scoring systems and laboratory methods such as proteomics have been suggested for both diagnosis and to predict disease severity, and research on these topics is still in progress. Novel therapeutic approaches with technological developments such as ERCP, ES, MRCP, and EUS are also suggested.

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis' most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    Acute coagulopathy of trauma predicts a poor clinical outcome. Tissue trauma activates the sympathoadrenal system resulting in high circulating levels of catecholamines that influence hemostasis dose-dependently through immediate effects on the two major compartments of hemostasis, i.......e., the circulating blood and the vascular endothelium. There appears to be a dose-dependency with regards to injury severity and the hemostatic response to trauma evaluated in whole blood by viscoelastic assays like thrombelastography (TEG), changing from normal to hypercoagulable, to hypocoagulable and finally......, is an evolutionary developed response that counterbalances the injury and catecholamine induced endothelial activation and damage.

    Full Text Available The simian immunodeficiency virus- (SIV- infected rhesus macaque is the preferred animal model for vaccine development, but the correlates of protection in this model are not completely understood. In this paper, we document the cytotoxic T lymphocyte (CTL response to SIV and its effects on viral evolution in an effort to identify events associated with disease progression regardless of MHC allele expression. We observed the evolution of epitopes targeted by CTLs in a group of macaques that included long-term nonprogressing (LTNP, slowly progressing (SP, normally progressing (NP, and rapidly progressing (RP animals. Collectively, our data (1 identify novel CTL epitopes from an SP animal that are not restricted by known protective alleles, (2 illustrate that, in this small study, RP and NP animals accrue more mutations in CTL epitopes than in SP or LTNP macaques, and (3 demonstrate that the loss of CTL responses to immunodominant epitopes is associated with viral replication increases, which are not controlled by secondary CTL responses. These findings provide further evidence for the critical role of the primary cell-mediated immune responses in the control of retroviral infections.

    A class of feed antennas and feed antenna arrays used in the focal plane of paraboloid reflectors and exhibiting higher than normal levels of cross-polarized radiation in the diagonal planes is addressed. A model which allows prediction of element gain and aperture efficiency of the feed/reflector system is presented. The predictions are in good agreement with experimental results. Tapered slot antenna (TSA) elements are used an example of an element of this type. It is shown that TSA arrays used in multibeam systems with small beam spacings are competitive in terms of aperture efficiency with other, more standard types of arrays incorporating waveguide type elements.

    Objective To investigate the predictive value of plasma copeptin for acute traumatic progressive hemorrhagic brain injury (PHI). Methods A total of 112 craniocerebral trauma patients from January 2012 to January 2015 were enrolled as the trauma group, and 112 healthy people served as the control group at the same time. The levels of plasma copeptin, glial fibrillary acidic protein (GFAP), myelin basic protein (MBP), neuron specific enolase (NSE),S100B, ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1), phosphorylated axonal neurofilament subunit H (pNF-H) and tau were detected and compared between the two groups. And the correlation between all above indices and Glasgow coma scale (GCS) scores were analyzed by Pearson correlation. The ROC was used to analyze the predictive value of these biomarkers and GCS scores for PHI. Results The plasma copeptin [(355 ± 124) pmol/L vs. (86 ± 30) pmol/L], GFAP [(0.14 ± 0.05) pmol/L vs. (0.05 ± 0.03) pmol/L], MBP [(0.61 ± 0.22)μmol/L vs. (0.23 ± 0.17)μmol/L], NSE [(0.11 ± 0.04) nmol/L vs. (0.05 ± 0.03) nmol/L], S100B [(15.5 ± 6.9) pmol/L vs. (2.6 ± 0.9) pmol / L], UCH-L1 [(66 ± 28) pmol / L vs. (10 ± 3) pmol / L], pNF-H [(2.52 ± 0.71) pmol / L vs. (0.14 ± 0.11) pmol / L] and tau [(4.4 ± 1.6) pmol / L vs. (0.4 ± 0.3) pmol / L] concentrations in the trauma group were much higher than those in the control group ( t=22.308, 19.418, 18.531, 16.928, 20.221, 21.063, 39.625, 27.025; all P < 0.001). Pearson correlation showed that GCS scores were all negative related with plasma copeptin, GFAP, MBP, NSE, S100B, UCH-L1, pNF-H and tau concentrations (r = -0.519, -0.478, -0.455, -0.422, -0.431,-0.408, -0.423, -0.421, all P<0.001). The ROC presented that GCS scores, plasma copeptin, GFAP, MBP, NSE, S100B, UCH-L1, pNF-H and tau concentrations all had significant predictive value for PHI (all P<0.05), and the area under curve (AUC) of GFAP (Z=2.693, P=0.007), MBP (Z=2.551, P=0.011), NSE (Z=2.397, P=0.017), S100B (Z=2.446, P=0

    Compositional analysis is central to determining the nutritional value of feedstuffs for use in ration formulation. The utility of the values and how they should be used depends on how representative the feed subsample is, the nutritional relevance and analytical variability of the assays, and whether an analysis is suitable to be applied to a particular feedstuff. Commercial analyses presently available for carbohydrates, protein, and fats have improved nutritionally pertinent description of feed fractions. Factors affecting interpretation of feed analyses and the nutritional relevance and application of currently available analyses are discussed.

    Objective To give a review and commentary on the treatment of acute foot and ankle injuries. Methods Based on the treatment experience and recent literature, a commentary on acute foot and ankle injuries were given, included the basic and clinical research results, evaluation before operation, and treatment methods of the soft tissue and bone injuries. Results The treatment of acute foot and ankle injuries is still a hot point in orthopaedic surgery. Operative and non-operative treatment of fresh Achilles tendon rupture can achieve satisfactory results, and early weight-bearing do not increase the re-rupture rate. The time delay between first debridement and injury within 24 hours does not increase the infection rate. For the treatment of severe ankle fractures, attentions should be paid to the cartilage injury, and anatomic reduction, good realignment, and the congruity recovery are very important. The treatment determination of calcaneal fractures depends on the fully understanding injury mechanisms, classifications, and treatment method. Talus fractures should try to be treated by experienced surgeons. Operation and fixation methods of Lisfranc injury depends on different injury types. Conclusion Acute foot and ankle injuries are common in clinical, to achieve a satisfactory result in evaluation and treatment, it is important to have a fully evaluation of the injury type, and choose the best operation time and suitable treatment methods, as well as to fully understand the biomechanical characteristics of different regions.%目的 对足踝部急性损伤的评估、治疗要点及相关进展进行评述.方法 根据临床治疗经验和近期文献报道结果,对常见的足踝部损伤,包括软组织损伤和骨性损伤的相关基础研究结果 、术前评估、合理及个体化的治疗方案选择进行分析评述,并对相关临床报道进行总结.结果 足踝部急性损伤的修复仍是临床和基础研究的热点.急性跟腱断裂手术

  5. Feed palatability and the alternative protein sources in shrimp feed

    2014-02-01

    Full Text Available Feed palatability in carnivorous aquaculture species, shrimps in particular, has been crucially related to the presence of compounds acting as attractants that are commonly associated with the prey components under wild conditions. Thus a nutritionally adequate and organoleptically-pleasing diet is essential to achieve satisfactory intake and growth in shrimps. Historically, fishmeal has been an essential dietary component of intensive shrimp cultures because of its nutrient composition and compounds of high attractability. However, in recent years the fishmeal supplies have been dwindling due to over hunting, a diminishing natural fish-stock, elevating prices and market volatility. This has led to search for cheaper sources of suitable protein as fishmeal substitutes. To improve the palatability of diets, various substances have been investigated for their effectiveness in aqua-feed including natural feed ingredients and synthetic flavor substances. For crustacean, attractants characteristically are of low molecular weight, water and ethanol soluble, and amphoteric or basic compounds that are released from potential prey items. Compounds such as free amino acids, especially taurine, hydroxyproline, glycine, arginine, glutamic acid and alanine have been identified to stimulate feeding in shrimps. The same has been identified with organic acids, nucleotides and nucleosides, betaine, and some small peptides. Palatability also has been associated with animal’s past experience with the feed. Understanding the factors that regulate feed palatability is therefore primary for successful shrimp culture.

  6. The Potential for Engineering Enhanced Functional-Feed Soybeans for Sustainable Aquaculture Feed.

    2016-01-01

    Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvested fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean's anti-nutritional proteins. To produce soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for vaccines, altered protein composition, and to produce high levels of β-carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

    Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

    Retrospective nutritional data on 100 children, aged 6 months to 2 1/2 years, who were admitted to the University Hospital in Kuala Lumpur, Malaysia, was obtained by interviewing the mothers of the children. Analysis of the data revealed that 1) only 49% of the children were breast-fed as infants; 2) 50% of the mothers who did breast-feed discontinued breast-feeding before the children were 3 months old; and 3) the weaning diet of at least 1/3 of the children was inadequate. 18% of the children were Malays, 49% were Chinese, and 33% were Indian. The proportion of breast-fed children was highest among the Malays and lowest among the Chinese. Mothers with higher incomes tended to stop breast-feeding earlier than mothers with lower incomes. 67% of the women said they stopped breast-feeding due to inadequate lactation. Most of the children received supplementary foods at relatively early ages. 50% of the infants received starchy foods by the time they were 3 1/2 months old, and 50% received fruit or fruit juice by the time they were 3 1/2 months old. Vegetable products, meat, fish, and eggs were not added to the diet until the children were considerably older. Recommendations, based on the study findings, were 1) hospitals should discontinue the practice of deferring breast-feeding initiation for 24 hours after delivery; 2) mothers should be encouraged to breast-feed fully; and 3) health personnel should discourage the widespread use of costly precooked cereals for supplementary feeding. Tables depicted 1) the frequency distribution of the 100 children by income and by milk feeding patterns according to ethnic affiliation and 2) the cost of serving precooked cereals as compared to the cost of serving home cooked meals.

    Clinicians, public health advisors, nutritionists and others have been attempting to increase breastfeeding rates for the last few decades, with varying degrees of success. We need social science researchers to help us understand the role of infant feeding in the family. Some researchers in the area of food and nutrition have found Pierre Bourdieu's theoretical framework helpful. In this editorial, I introduce some of Bourdieu's ideas and suggest researchers interested in infant feeding should consider testing these theories. PMID:21676218

    Full Text Available The paper will demonstrate the quality of some feed used in swine diet. The emphasis will be on feed whose incorporation into mixes could result in unfavorable effects on production, health and economic production of swine. Data will be presented on maize and its possible negative effects, having in mind toxins. Soybean meal, or genetically modified soybean meal, will also be observed. The next feed which will be discussed will be soybean whey obtained by different procedures and the potential dangers of its use in swine diet rations. Sunflower meal, feed of animal origin, with emphasis on fish flour and meat-bone flour will also be covered in the work. A feed which has been attracting particular attention lately is yeast imported from Italy. Its quality characteristics will be discussed, the so-called non-protein nitrogen. Analyses of mineral feed will include sources of phosphorus, phosphates (monocalciumphosphate, dicalcium phosphate phytases and resolving the problem of phosphorus in swine rations. Finally, an inevitable segment are synthetic amino acids, especially lysine and its role in swine diet.

    2009-03-01

    We report a case of acute respiratory failure due to refeeding syndrome caused by hypocaloric enteral tube feeds. A 60-y-old obese man, with a diagnosis of esophageal carcinoma with local metastases, underwent feeding jejunostomy tube insertion. Enteral tube feeding was initiated at small volumes providing 4.4 kcal x kg(-1) x d(-1) and gradually increased over 48 h to 29 kcal x kg(-1) x d(-1) (based on adjusted body weight). The patient then developed acute respiratory distress requiring intubation and ventilatory support. Serum phosphorus (P) level was extremely low at 4 d to adequately correct the electrolyte derangements. Successful liberation from mechanical ventilation was then possible. In chronically malnourished patients undergoing nutritional support, even hypocaloric feeding should be considered a risk factor for developing refeeding syndrome leading to severe and acute electrolyte fluid-balance and metabolic abnormalities.

By definition a child provided with prelacteal feed (PLF is not exclusively breastfed and PLF has many implications for the success and early initiation of breastfeeding. Objectives. To describe the prevalence of, nature of, and reasons for and factors associated with PLF. Methods. 647 mother-infant dyads were studied. Data was collected about the sociodemographic features of the family and baby, maternity care, the type of first feed before suckling, and causes of PLF. Maternal weight and height were measured and body mass index was calculated. Results. About 58% of newborns received prelacteal feeds. The commonest PLF was sugar/glucose water (39.6%. The most frequent reasons for giving PLF are tradition (61.0% and mother’s/mother in law’s advice (58.3%. The logistic regression revealed that the independent predictors of PLF are urban residence; maternal education; father’s education; low, middle, and high social class; maternal obesity; receiving antenatal care at private clinics and no antenatal care; Caesarean section; female babies; low birth weight; and admission to neonatal intensive care. Conclusion. Indiscriminate use of PLF should be discouraged in medical education and in antenatal maternal health education.

    2014-01-01

    During critical periods of development early in life, excessive or scarce nutritional environments can disrupt the development of central feeding and metabolic neural circuitry, leading to obesity and metabolic disorders in adulthood. A better understanding of the genetic networks that control the development of feeding and metabolic neural circuits, along with knowledge of how and where dietary signals disrupt this process, can serve as the basis for future therapies aimed at reversing the public health crisis that is now building as a result of the global obesity epidemic. This review of animal and human studies highlights recent insights into the molecular mechanisms that regulate the development of central feeding circuitries, the mechanisms by which gestational and early postnatal nutritional status affects this process, and approaches aimed at counteracting the deleterious effects of early over- and underfeeding.

    Near-infrared images of the active galaxy NGC 1097, obtained with the NACO adaptive optics instrument on ESO's Very Large Telescope, disclose with unprecedented detail a complex central network of filamentary structure spiralling down to the centre of the galaxy. These observations provide astronomers with new insights on how super-massive black holes lurking inside galaxies get fed. "This is possibly the first time that a detailed view of the channelling process of matter, from the main part of the galaxy down to the very end in the nucleus is released," says Almudena Prieto (Max-Planck Institute, Heidelberg, Germany), lead author of the paper describing these results. Located at a distance of about 45 million light-years in the southern constellation Fornax (the Furnace), NGC 1097 is a relatively bright, barred spiral galaxy seen face-on. At magnitude 9.5, and thus just 25 times fainter than the faintest object that can be seen with the unaided eye, it appears in small telescopes as a bright, circular disc. NGC 1097 is a very moderate example of an Active Galactic Nucleus (AGN), whose emission is thought to arise from matter (gas and stars) falling into oblivion in a central black hole. However, NGC 1097 possesses a comparatively faint nucleus only, and the black hole in its centre must be on a very strict "diet": only a small amount of gas and stars is apparently being swallowed by the black hole at any given moment. Astronomers have been trying to understand for a long time how the matter is "gulped" down towards the black hole. Watching directly the feeding process requires very high spatial resolution at the centre of galaxies. This can be achieved by means of interferometry as was done with the VLTI MIDI instrument on the central parts of another AGN, NGC 1068 (see ESO PR 17/03), or with adaptive optics [1]. Thus, astronomers [2] obtained images of NGC 1097 with the adaptive optics NACO instrument attached to Yepun, the fourth Unit Telescope of ESO's VLT

    急性白血病(AL)是一类起源于白血病干细胞(LSC)的恶性克隆性疾病,且死亡率高.尽管联合化疗和造血干细胞移植明显改善了AL患者的完全缓解率和总体生存期,但耐药和复发仍是治疗的难题.越来越多的研究表明,白血病耐药和复发的原因之一是骨髓微环境对LSC的保护作用,LSC隐蔽在骨髓微环境中从而逃避化疗药物的杀伤,并在骨髓微环境内自我更新,还可通过改变骨髓微环境而促进AL的发展.因此,通过靶向调控骨髓微环境与LSC间的相互作用,有望找到治疗AL的新方法.%Acute leukemia (AL) is a kind of malignant clonal disease initiated by leukemia stem cells (LSC) with a high mortality.Although combined chemotherapy and hematopoietic stem cell transplantation significantly improved the complete remission rate and overall survival in AL patients,chemoresistance and relapse are still great challenges.Recently,increasing results of studies showed that LSC protected by bone marrow microenvironment was responsible in part of for AL relapse and chemoresistance.LSC hide in the bone marrow microenvironment to escape the killing of chemotherapy drugs and remain self-renewal ability.Furthermore,LSC also promote leukemogenesis by modulating the bone marrow microenvironment.Taken together,targeting the interaction between bone marrow microenvironment and LSC may provide a new promising and novel therapeutic strategies for curing AL.

    β-及γ-catenin均参与白血病干细胞(LSC)的自我更新过程,在急性髓细胞白血病(AML)中存在异常表达及易位,因此其可能成为清除LSC的新治疗靶点.β-catenin是经典Wnt信号通路中的关键细胞因子,其异常表达及核易位是AML预后不良的独立危险因素.新近研究结果显示,体外抑制β-catenin表达可以杀伤AML及其LSC.而γ-catenin是β-catenin的同源蛋白,在白血病中可以通过β-catenin依赖或非依赖途径发挥生物学作用.笔者就近年来,β及γ-catenin在AML及其LSC中的研究进展进行综述.%Overexpression and aberrant nuclear localization of β-catenin and γ-catenin is frequent in acute myelogenous leukemia (AML).They participate in the process of the leukemia stem cell (LSC) self-renewal,and may be important targets for elimination of LSC.β-catenin is a key signal transducer factor in the canonical Wnt pathway,and its abnormal expression and nuclear translocation is an independent risk factor for poor prognosis in AML.Recent studies showed that inhibition of β-catenin can kill AML and its LSC in vitro.γ-catenin,as a homologous protein to β-catenin,plays its biologic role through dependent or non-dependent on the β-catenin pathway.This article reviews literatures on advances of β-catenin and γ-catenin in AML and its LSC.

    Reported in vitro data implicated soluble CD40 ligand (sCD40L) in endothelial dysfunction and angiogenesis. However, whether sCD40L could exert that influence in endothelial dysfunction and angiogenesis after injury in acute myocardial infarction (AMI) patients remains unclear. In the present study, we evaluated the association of sCD40L with markers of platelet activation, endothelial, and vascular function during a recovery period early after AMI. To achieve this goal, the time changes of soluble, platelet-bound, and microparticle-bound CD40L levels over 1 month were assessed in AMI patients and correlated with endothelial nitric oxide synthase (eNOS) polymorphisms, vascular endothelial growth factor (VEGF) concentrations, and platelet expression of P-selectin (CD62P). The association of soluble form, platelet-bound, and microparticle-bound CD40L with CD62P expression on platelets, a marker of platelet activation, was also assessed to evaluate the role of CD40L in the thrombosis, whereas the association with eNOS and VEGF was to evaluate the role of CD40L in vascular dysfunction. This work shows for the first time that time changes of sCD40L over 1 month after myocardial infarct onset were associated with G894T eNOS polymorphism and with the VEGF concentrations, but not to the platelet CD62P expression. These results indicate that, in terms of AMI pathophysiology, the sCD40L cannot be consider just as being involved in thrombosis and inflammation but also as having a relevant role in vascular and endothelial dysfunction.

    Contrast-associated acute kidney injury (CAAKI) is a common iatrogenic condition. The principal risk factors for CAAKI are underlying renal impairment; diabetes in the setting of kidney disease; and intravascular volume depletion, effective or absolute. CAAKI is associated with serious adverse short-term and long-term outcomes, including mortality and more rapidly progressive chronic kidney disease, although the causal nature of these associations remains unproved. Patients with chronic kidney disease and other risk factors for CAAKI who present with acute coronary syndrome should undergo indicated angiographic procedures.

    In fish, the voluntary feed intake is influenced by dietary, environmental and/or physiological factors. It is well known that under hypoxia the concentration of oxygen in the water (DO) determines the feed intake of fish. However at non-limiting water DO levels (normoxia), several other mechanisms might play a role in feed intake regulation. Under hypoxia feed intake and oxygen consumption are interrelated. In this thesis we proposed the ‘oxystatic’ concept of feed intake regulat...

    Full Text Available Tumor lysis syndrome is a serious and dangerous complication usually associated with antiblastic treatment in some malignancies characterized by high cell turn-over. Mild or severe electrolyte abnormalities including high serum levels of uric acid, potassium, phosphorus, creatinine, bun and reduction of calcium can be responsible for multi-organ failure, involving mostly kidneys, heart and central nervous system. Renal damage can be followed by acute renal failure, weight gain, progressive liver impairment, overproduction of cytokines, and subsequent maintenance of multi-organ damage. Life-threatening acute respiratory failure associated with tumor lysis syndrome is rare. We describe a child with T-cell acute lymphoblastic leukemia, who developed an unusually dramatic tumor lysis syndrome, after administration of the first low doses of steroid, that was rapidly associated with severe acute respiratory distress syndrome. Subsequent clinical course and treatment modalities that resulted in the gradual and full recovery of the child are also described.

  2. Salmonella Radicidation of Dry Mixed Feeds and Feed Ingredients

    International Nuclear Information System (INIS)

    Feed components contaminated with salmonellae act as vehicles in the transmission of these bacteria to slaughter animals and hence to meat and poultry. Terminal decontamination of ingredients or mixed feed seems required because sanitary improvements in processing, bagging and storage do not always appear effective in considerably reducing salmonella contamination rates. Experiments were carried out to assay the decontamination effect of pelletization of mixed feed. Enumeration of enterobacteriaceae was used as the analytical criterion. It appeared that a temperature over 80°C generally led to five decimal reductions in enterobacteriaceae counts; however, also currently used lower temperatures may bring about two decimal reductions only. Following earlier experiments with fish meal, range finding tests on the decontamination of mixed feed with 60Co gamma rays were also performed. To achieve five decimal reductions in the counts of the most resistant enterobacteriaceae which were encountered about 0.5 Mrad was required; survival curves were generally not linear, so that overall effective dose had to be used as a parameter. Feeding experiments with rats, using 35% fish meal irradiated at 0.8 Mrad in the diet for two years, demonstrated that neither losses of nutritive value nor the occurrence of orally toxic factors is effected by such an irradiation treatment. It is recommended that pilot plant tests be carried out. In these tests an attempt should be made to combine improved sanitation and pelletizing with a terminal radiation treatment of the bagged material with the lowest dose required. Such tests should preferably be carried out in suitable areas of countries like Peru or Chile. A brief outline is given of the development work and training of scientific and technical staff that should be carried out during the installation of such a pilot plant. (author)

    Acute pancreatitis is an acute inflammation of the pancreas. Several classification systems have been used in the past but were considered unsatisfactory. A revised Atlanta classification of acute pancreatitis was published that assessed the clinical course and severity of disease; divided acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis; discerned an early phase (first week) from a late phase (after the first week); and focused on systemic inflammatory response syndrome and organ failure. This article focuses on the revised classification of acute pancreatitis, with emphasis on imaging features, particularly on newly-termed fluid collections and implications for the radiologist.

    The catalytic reforming of naphtha is one of the major refinery processes, designed to increase the octane number of naphtha or to produce aromatics. The naphtha used as catalytic reformer feedstock usually contains a mixture of paraffins, naphthenes, and aromatics in the carbon number range C{sub 6} to C{sub 10}. The detailed chemical composition of the feed is necessary to predict the aromatics and hydrogen production as well as the operation severity. The analysis of feed naphtha is usually reported in terms of its ASTM distillation curve and API or specific gravity. Since reforming reactions are described in terms of lumped chemical species (paraffins, naphthenes and aromatics), a feed characterisation technique should be useful in order to predict reforming operating conditions and detect feed quality changes. Unfortunately online analyzer applications as cromatography or recently introduced naphtha NMR [1] are scarce in most of refineries. This work proposes an algorithmic characterisation method focusing on its main steps description. The method could help on the subjects previously described, finally a calculation example is shown.

    To evaluate the status of feeding practices and analyze the association between feeding practice and health status among Tibetan infants, a cross-sectional survey of 386 women with children aged under 24 months was conducted in rural areas surrounding Lhasa, Tibet. All participants were selected using simple random sampling and were interviewed face-to-face by trained interviewers. Mothers were interviewed to collect information on their feeding practices. A feeding practices index was created using the rank sum ratio method. Most of the infants had been or were being breastfed at the time of the interview. The feeding practices index was significantly and inversely associated with the prevalence of acute upper respiratory infection, and the odds ratio for the qualified feeding practices index vs. the non-qualified feeding practices index was 0.43 (95% confidence interval: 0.20-0.94). There were no measurable associations observed between acute upper respiratory infection, diarrhea, and the feeding practices index after controlling for selected factors. The method of rank sum ratio provides a flexible way to evaluate feeding practices and is easy to understand. Furthermore, appropriate infant feeding practices might play a protective role in Tibetan infants' health.

  13. Obstructive acute abdomen: reviewing important points

    International Nuclear Information System (INIS)

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis.

    Full Text Available Abstract Background The human right to adequate food needs to be interpreted for the special case of young children because they are vulnerable, others make the choices for them, and their diets are not diverse. There are many public policy issues relating to child feeding. Discussion The core of the debate lies in differences in views on the merits of infant formula. In contexts in which there is strong evidence and a clear consensus that the use of formula would be seriously dangerous, it might be sensible to adopt rules limiting its use. However, until there is broad consensus on this point, the best universal rule would be to rely on informed choice by mothers, with their having a clearly recognized right to objective and consistent information on the risks of using different feeding methods in their particular local circumstances. Summary The obligation of the state to assure that mothers are well informed should be viewed as part of its broader obligation to establish social conditions that facilitate sound child feeding practices. This means that mothers should not be compelled to feed in particular ways by the state, but rather the state should assure that mothers are supported and enabled to make good feeding choices. Thus, children should be viewed as having the right to be breastfed, not in the sense that the mother is obligated to breastfeed the child, but in the sense that no one may interfere with the mother's right to breastfeed the child. Breastfeeding should be viewed as the right of the mother and child together.

    After acute myocardial infarction, ventricular remodeling is characterized by changes at the molecular, structural, geometrical and functional level that determine progression to heart failure. Inflammation plays a key role in wound healing and scar formation, affecting ventricular remodeling. Several, rather different, components of the inflammatory response were studied as biomarkers in ST-elevation acute myocardial infarction. Widely available and inexpensive tests, such as leukocyte count at admission, as well as more sophisticated immunoassays provide powerful predictors of adverse outcome in patients with ST-elevation acute myocardial infarction. We review the value of inflammatory markers in ST-elevation acute myocardial infarction and their association with ventricular remodeling, heart failure and sudden death. In conclusion, the use of these biomarkers may identify subjects at greater risk of adverse events and perhaps provide an insight into the mechanisms of disease progression.

  16. When Breast-feeding is not Contraindicated: Do you know when to stop breast-feeding?

    OpenAIRE

    Newman, Jack

    1991-01-01

    As more mothers elect to breast-feed, more concomitant problems in mothers and babies are reported that are thought to contraindicate breast-feeding. Many frequently cited maternal and infant reasons for stopping breast-feeding are not valid. Breast-feeding can usually be maintained if the physician remembers that breast-feeding is important for the baby and mother and not simply another feeding method.

    An estimated 165 million children are stunted due to the combined effects of poor nutrition, repeated infection and inadequate psychosocial stimulation. The complementary feeding period, generally corresponding to age 6-24 months, represents an important period of sensitivity to stunting with lifelong, possibly irrevocable consequences. Interventions to improve complementary feeding practices or the nutritional quality of complementary foods must take into consideration the contextual as well as proximal determinants of stunting. This review presents a conceptual framework that highlights the role of complementary feeding within the layers of contextual and causal factors that lead to stunted growth and development and the resulting short- and long-term consequences. Contextual factors are organized into the following groups: political economy; health and health care systems; education; society and culture; agriculture and food systems; and water, sanitation and environment. We argue that these community and societal conditions underlie infant and young child feeding practices, which are a central pillar to healthy growth and development, and can serve to either impede or enable progress. Effectiveness studies with a strong process evaluation component are needed to identify transdisciplinary solutions. Programme and policy interventions aimed at preventing stunting should be informed by careful assessment of these factors at all levels.

    Global demand for feed, especially cereal feed, is expected to increase in the decades to come. At the global level, demand for cereal feed will be met by the supply. There are, however, disparities between regions. As a result of strong livestock industry development, the Asian region as a whole will have a shortage of cereal feed and will become a major cereal feed importer. This paper examines existing projections of feed demand and supply in the Asian region. It also sheds light on the im...

    Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent of the level of production, and the lower the value the more efficient the animal is. This paper examines the current state of knowledge o...

    2009-10-20

    A feeding mechanism and method for feeding minute items, such as capacitors, resistors, or solder preforms. The mechanism is adapted to receive a plurality of the randomly-positioned and randomly-oriented extremely small or minute items, and to isolate, orient, and position one or more of the items in a specific repeatable pickup location wherefrom they may be removed for use by, for example, a computer-controlled automated assembly machine. The mechanism comprises a sliding shelf adapted to receive and support the items; a wiper arm adapted to achieve a single even layer of the items; and a pushing arm adapted to push the items into the pickup location. The mechanism can be adapted for providing the items with a more exact orientation, and can also be adapted for use in a liquid environment.

    Feed palatability in carnivorous aquaculture species, shrimps in particular, has been crucially related to the presence of compounds acting as attractants that are commonly associated with the prey components under wild conditions. Thus a nutritionally adequate and organoleptically-pleasing diet is essential to achieve satisfactory intake and growth in shrimps. Historically, fishmeal has been an essential dietary component of intensive shrimp cultures because of its nutrient composit...

    Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count. She was successfully managed by craniotomy and evacuation of subdural hematoma with intraoperative transfusion of platelets. The acute spontaneous subdural hematoma in her was probably related to the bleeding diathesis due to thrombocytopenia associated with chemotherapy.

  5. Acute otitis media and acute bacterial sinusitis.

    Wald, Ellen R

    2011-05-01

    Acute otitis media and acute bacterial sinusitis are 2 of the most common indications for antimicrobial agents in children. Together, they are responsible for billions of dollars of health care expenditures. The pathogenesis of the 2 conditions is identical. In the majority of children with each condition, a preceding viral upper respiratory tract infection predisposes to the development of the acute bacterial complication. It has been shown that viral upper respiratory tract infection predisposes to the development of acute otitis media in 37% of cases. Currently, precise microbiologic diagnosis of acute otitis media and acute bacterial sinusitis requires performance of tympanocentesis in the former and sinus aspiration in the latter. The identification of a virus from the nasopharynx in either case does not obviate the need for antimicrobial therapy. Furthermore, nasal and nasopharyngeal swabs are not useful in predicting the results of culture of the middle ear or paranasal sinus. However, it is possible that a combination of information regarding nasopharyngeal colonization with bacteria and infection with specific viruses may inform treatment decisions in the future.

    2011-04-01

    The United Nations Convention on the Rights of the Child holds governments responsible to ensure children's right to the highest attainable standard of health by providing breastfeeding support, and access to nutritious foods, appropriate health care, and clean drinking water. International experts have identified key child care practices and programmatic activities that are proven to be effective at reducing infant and young child undernutrition, morbidity, and mortality. Nevertheless, progress towards reducing the prevalence of undernutrition has been sporadic across countries of the Sahel sub-region of Sub-Saharan Africa. In view of this uneven progress, a working group of international agencies was convened to 'Reposition children's right to adequate nutrition in the Sahel.' The first step towards this goal was to organize a situational analysis of the legislative, research, and programmatic activities related to infant and young child nutrition (IYCN) in six countries of the sub-region: Burkina Faso, Chad, Mali, Mauritania, Niger, and Senegal. The purposes of this introductory paper are to review current information concerning the nutritional and health status of infants and young children in the Sahel and to summarize international guidelines on optimal IYCN practices. These guidelines were used in completing the above-mentioned situational analyses and encompass specific recommendations on: (i) breastfeeding (introduction within the first hour after birth, exclusivity to 6 months, continuation to at least 24 months); (ii) complementary feeding (introduction at 6 months, use of nutrient dense foods, adequate frequency and consistency, and responsive feeding); (iii) prevention and/or treatment of micronutrient deficiencies (vitamin A, zinc, iron and anaemia, and iodine); (iv) prevention and/or treatment of acute malnutrition; (v) feeding practices adapted to the maternal situation to reduce mother-to-child transmission of HIV; (vi) activities to ensure food

    Acute pancreatitis in pregnancy is rare and occurs in approximately 3 in 10,000 pregnancies. It rarely complicates pregnancy, and can occur during any trimester, however over half (52%) of cases occur during the third trimester and during the post-partum period. Gallstones are the most common cause of acute pancreatitis. On the other hand, acute pancreatitis caused by hypertriglyceridemia due to increase of estrogen during the gestational period is very unusual, but complication carries a higher risk of morbidity and mortality for both the mother and the fetus. We experienced a case of pregnant woman who died of acute exacerbation of hypertriglyceridemia-induced acute pancreatitis at 23 weeks of gestation. We report on progress and management of this case along with literature reviews.

  14. The Progressive BSSG Rat Model of Parkinson's: Recapitulating Multiple Key Features of the Human Disease.

    Directory of Open Access Journals (Sweden)

    Jackalina M Van Kampen

    Full Text Available The development of effective neuroprotective therapies for Parkinson's disease (PD has been severely hindered by the notable lack of an appropriate animal model for preclinical screening. Indeed, most models currently available are either acute in nature or fail to recapitulate all characteristic features of the disease. Here, we present a novel progressive model of PD, with behavioural and cellular features that closely approximate those observed in patients. Chronic exposure to dietary phytosterol glucosides has been found to be neurotoxic. When fed to rats, β-sitosterol β-d-glucoside (BSSG triggers the progressive development of parkinsonism, with clinical signs and histopathology beginning to appear following cessation of exposure to the neurotoxic insult and continuing to develop over several months. Here, we characterize the progressive nature of this model, its non-motor features, the anatomical spread of synucleinopathy, and response to levodopa administration. In Sprague Dawley rats, chronic BSSG feeding for 4 months triggered the progressive development of a parkinsonian phenotype and pathological events that evolved slowly over time, with neuronal loss beginning only after toxin exposure was terminated. At approximately 3 months following initiation of BSSG exposure, animals displayed the early emergence of an olfactory deficit, in the absence of significant dopaminergic nigral cell loss or locomotor deficits. Locomotor deficits developed gradually over time, initially appearing as locomotor asymmetry and developing into akinesia/bradykinesia, which was reversed by levodopa treatment. Late-stage cognitive impairment was observed in the form of spatial working memory deficits, as assessed by the radial arm maze. In addition to the progressive loss of TH+ cells in the substantia nigra, the appearance of proteinase K-resistant intracellular α-synuclein aggregates was also observed to develop progressively, appearing first in the

    2007-07-01

    Full Text Available The pathogenesis of acute pancreatitis relates to the inappropriate activation of trypsinogen to trypsin and a lack of the prompt elimination of the active trypsin inside the pancreas. Therefore, trypsin is believed to be the key enzyme in the initiation and exacerbation of acute pancreatitis by activating pancreatic zymogens. The activation of digestive enzymes causes pancreatic injury and results in an inflammatory response. The acute inflammatory response in the pancreas induces the systemic production of cytokines causing substantial tissue damage, and may progress beyond the pancreas to a systemic inflammatory response syndrome (SIRS, multi-organ failure (MOF or death [1]. In several studies, protease inhibitors have not been shown to be of significant value in the treatment of acute pancreatitis and are not available in the United States [2]. Several guidelines [3, 4, 5, 6, 7, 8, 9, 10, 11, 12] on the treatment of acute pancreatitis do not recommend them and the debate about the use of protease inhibitors is mentioned.

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    Full Text Available The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare. A randomized block design in a factorial scheme (3 × 2 with three feeding levels (30, 60 and 90 g/kg of body weight (BW/day and two feeding frequencies (1x and 2x/day was set up in duplicate, representing 24 experimental units. Data were analyzed using two-way ANOVA and the Tukey test for comparison between means. After 84 days, results indicated that both factors influenced fish performance. No interaction between these factors was, however, observed. Increased feeding level and feeding frequency resulted in increased feed intake. The feed conversion ratio was negatively affected by feeding level, but not affected by feeding frequency. Final weights were higher when fish were fed twice daily, at levels of 60 or 90 g/kg BW/day. Specific growth rate was higher when fish received 60 or 90 g/kg BW/day, regardless of the feeding frequency. Survival was not affected by any treatment, with mean survival rates higher than 90%. It is recommended that juveniles be fed at a level of 60 g/kg BW/day with a minimum of two meals per day, to attain optimal survival, growth and feed efficiency.

    The incidence of acute pancreatitis in Japan is increasing and ranges from 187 to 347 cases per million populations. Case fatality was 0.2% for mild to moderate, and 9.0% for severe acute pancreatitis in Japan in 2003. Experts in pancreatitis in Japan made this document focusing on the practical aspects in the early management of patients with acute pancreatitis.The correct diagnosis of acute pancreatitis and severity stratification should be made in all patients using the criteria for the diagnosis of acute pancreatitis and the multifactor scoring system proposed by the Research Committee of Intractable Diseases of the Pancreas as early as possible. All patients diagnosed with acute pancreatitis should be managed in the hospital.Monitoring of blood pressure, pulse and respiratory rate,body temperature, hourly urinary volume, and blood oxygen saturation level is essential in the management of such patients. Early vigorous intravenous hydration is of foremost importance to stabilize circulatory dynamics. Adequate pain relief with opiates is also important. In severe acute pancreatitis, prophylactic intravenous administration of antibiotics at an early stage is recommended. Administration of protease inhibitors should be initiated as soon as thediagnosis of acute pancreatitis is confirmed. A combination of enteral feeding with parenteral nutrition from early stage is recommended if there are no clear signs and symptoms of ileus and gastrointestinal bleeding. Patients with severe acute pancreatitis should be transferred to ICU as early as possible to perform special measures such as continuous regional arterial infusion of protease inhibitors and antibiotics, and continuous hemodiafiltration. The Japanese Government covers medical care expense for severe acute pancreatitis as one of the projects of Research on Measures for Intractable Diseases.

    Examples of the merits of blue-sky research in the history of science are legion. The invention of the laser, celebrating its 50th anniversary this year, is an excellent example. When it was invented it was considered to be 'a solution waiting for a problem', and yet the level to which it has now infiltrated our day-to-day technological landscape speaks volumes. At the same time it is also true to say that the direction of research is also at times rightly influenced by the needs and concerns of the general public. Over recent years, growing concerns about the environment have had a noticeable effect on research in nanotechnology, motivating work on a range of topics from green nanomaterial synthesis [1] to high-efficiency solar cells [2] and hydrogen storage [3]. The impact of the world's energy consumption on the welfare of the planet is now an enduring and well founded concern.

    Examples of the merits of blue-sky research in the history of science are legion. The invention of the laser, celebrating its 50th anniversary this year, is an excellent example. When it was invented it was considered to be 'a solution waiting for a problem', and yet the level to which it has now infiltrated our day-to-day technological landscape speaks volumes. At the same time it is also true to say that the direction of research is also at times rightly influenced by the needs and concerns of the general public. Over recent years, growing concerns about the environment have had a noticeable effect on research in nanotechnology, motivating work on a range of topics from green nanomaterial synthesis [1] to high-efficiency solar cells [2] and hydrogen storage [3]. The impact of the world's energy consumption on the welfare of the planet is now an enduring and well founded concern. In the face of an instinctive reluctance to curtail habits of comfort and convenience and the appendages of culture and consumerism, research into renewable and more efficient energy sources seem an encouraging approach to alleviating an impending energy crisis.

    Full Text Available The use of antibiotics as feed additive improves performance in livestock. However, scientific data related to the use of antibiotics in feed merge spreading of bacterial resistance in animal and human bodies, therefore the usage of antibiotics in animal production is restricted. This condition raise the utilization of natural antibiotic as functional feed such as phytogenics (essential oil, flavonoid, saponin, and tannin, enzyme, probiotic, and prebiotic to improve the livestock’s performance, quality, and health. Functional feeds increase profitability in animal husbandry production and its use is feeds are expected to be functional foods that may have positive effects in human nutrition.

    Full Text Available Context Percutaneous endoscopic gastrostomy (PEG feedings are generally considered safe with few serious complications. Acute pancreatitis is a rare complication associated with replacement percutaneous endoscopic gastrostomy tubes. Case report We report two cases of acute pancreatitis induced by migrated replacement percutaneous endoscopic gastrostomy tubes. Conclusions Migration of a balloon into the duodenum can result in external manipulation of the ampulla of Vater thereby disturbing the flow of pancreatic secretions leading to acute pancreatitis. Recognition of this complication is important and should be included as potential etiology of acute pancreatitis in patients receiving percutaneous endoscopic gastrostomy feedings. Periodic examination and documentation of the distance of the balloon from the skin should be performed to document the position of the tubes or any inadvertent migration of the tubes. The use of Foley catheters as permanent replacement tubes should be considered medically inappropriate.

    1997-01-01

    During the hospitalization in the Dhaka hospital of the international Centre for Diarrhoeal Disease Research, Bangladesh, of a group of partially breast-fed infants aged 1-12 weeks who had been admitted with acute diarrhoea, their mothers were individually counselled by breast-feeding counsellors to start exclusive breast-feeding. The counselling was repeated 1 week later at home, and the women's infant-feeding practices were evaluated 2 weeks after their infants had been discharged from hospital. A total of 25% of the mothers failed to breast-feed exclusively despite having been counselled. The case studies of these mothers illustrate that although they generally complained about having "insufficient breast milk" various factors such as domineering grandmothers, lack of financial support by their husbands, too much housework, or disinterest contributed to their failure to breast-feed exclusively. While family support is essential for all lactating mothers, women with familial or financial problems require special attention and extra counselling sessions so that they can be helped to identify how to achieve and sustain exclusive breast-feeding.

    Early nutrition is considered to be crucial for development of persistent obesity in later life. The aim of this paper is to present an overview of complementary feeding patterns across European countries. Most European infants introduce solid foods earlier than 6 completed months of age as recommended by WHO. The commonest risk factors for early introduction of solid foods have been shown to be smoking mothers of young age, low SES and no breastfeeding. The foods most frequently introduced as first solids are fruit and cereals followed by other foods that vary depending on the country of residence and the infants' type of feeding. Insufficient updated information has been made available in Europe in terms of infants' nutrient intake during complementary feeding, as well as on the potential acute metabolic effects of complementary feeding. Websites, e-forums and blogs on complementary feeding are widely spread in the web. The recipes and daily menus published in food industry websites are often nutritionally incorrect. Baby led-weaning (BLW) is based on the principle that babies, upon being started on complementary foods, should be allowed to eat whatever food they want (regular family foods included) in its normal shape. No nutrient intake and metabolic data are nevertheless available about BLW. The current scenario in terms of our understanding of complementary feeding in Europe opens several new research avenues. Not using and not improving our current knowledge of nutrition to improve children's health represents an infringement of children's rights.

    Vitz, P C; Hazan, D N

    1974-01-01

    Learning of simple numerical progressions and compound progressions formed by combining two or three simple progressions is investigated. In two experiments, time to solution was greater for compound vs simple progressions; greater the higher the progression's solution level; and greater if the progression consisted of large vs small numbers. A set of strategies is proposed to account for progression learning based on the assumption S computes differences between integers, differences between differences, etc., in a hierarchical fashion. Two measures of progression difficulty, each a summary of the strategies, are proposed; C1 is a count of the number of differences needed to solve a progression; C2 is the same count with higher level differences given more weight. The measures accurately predict in both experiments the mean time to solve 16 different progressions with C2 being somewhat superior. The measures also predict the learning difficulty of 10 other progressions reported by Bjork (1968).

    Background Growth and development of infants has been an impoRant topic in pediatrics for a long time.Infants must be provided with food containing all necessary nutrienls.Breast milk js believed to be the most desirable natural and cheapest food for well-balanced nutrition.But with the progress in the development of substitute food in developed countries,it is thought that formula milk can meet the requirement for infant growth.During early infancy,growth,as the most sensitive index of health,is therefore a critical component in evaluating the adequacy of breast-feeding,mixed-feeding and formula feeding.Iron status is another important index of infant health.Iron deficiency anemia remains the most prevalent nutritional deficiency index in infants worldwide.This study is to compare infants in Beijing at 4 months who are on three different feeding modes(breast feeding,mixed feeding and formula feeding)in physical changes and iron status.The results may provide new mothers with support in feeding mode selection,which will also be helpful to the China Nutrition Association in feeding mode education.Methods This is a cohort study.One thousand and one normal Beijing infants were followed regularly for 12 months.Body weight and horizontal length were measured.Hemoglobin,red blood cell counts,mean corpuscular volume,mean corpuscular hemoglobin and serum iron were analyzed at 4 months.Results The breast feeding percentage in the first 4 months was 47.9%.The feeding mode was not significantly related to maternal delivery age,education,labor pathway nor infant sex(P>0.05).Infant boys and girls exclusively breast-fed from 0 to 4 months had the highest weight at 0-6 months.The anemia rate of breast-fed infant boys at 4 months was the highest.Conclusions Breast feeding should be given more emphasis.It is compulsory for new mothers to breast-feed their Infants if possible.Social environment should also guarantee the requirement for breast feeding.Furthermore the normal values

We have used different com-binations of the keywords of“abdominal trauma”,“liver”,“spleen”,“renal”, to review the reference list of retrieved articles for further relevant studies. Nowadays, we are facing a major change in abdominal trauma therapeutic approach, due to the continuous extending indications and very high successful rate of selective nonoperative management, completed or not with minimally invasive techniques like angiography and angiographic embolization. New imaging methods offer a high-quality characterization of solid organ injuries, being a secure support for decision algorithm in polytrauma patients. After a continuous decrease in number of laparotomies for trauma, new techniques should be developed for maintaining and developing the trauma surgeons' skills. According to the current standards, for a low morbidity and mortality, the trauma patients may be approached by a multidisciplinary and experienced trauma team. Even if nonoperative management is continuously expanding, this may be applied only by a trained and skillful trauma surgeon, who is able to perform difficult surgical techniques at any moments.

  18. The research progress of acute small bowel perforation

    2015-01-01

    This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multiorgan failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

    2016-06-01

    Full Text Available ABSTRACT Objective: To draw attention to the importance of interaction between caregiver and child during feeding and the influence of parenting style on dietary habit formation. Source of data: A search was performed in the PubMed and Scopus databases for articles addressing responsive feeding; the articles considered most relevant by the authors were selected. Synthesis of data: The way children are fed is decisive for the formation of their eating habits, especially the strategies that parents/caregivers use to stimulate feeding. In this context, responsive feeding has been emphasized, with the key principles: feed the infant directly and assist older children when they already eat on their own; feed them slowly and patiently, and encourage children to eat but do not force them; if the child refuses many types of foods, experiment with different food combinations, tastes, textures, and methods of encouragement; minimize distractions during meals; and make the meals an opportunity for learning and love, talking to the child during feeding and maintaining eye contact. It is the caregiver's responsibility to be sensitive to the child's signs and alleviate tensions during feeding, and make feeding time pleasurable; whereas it is the child's role to clearly express signs of hunger and satiety and be receptive to the caregiver. Conclusion: Responsive feeding is very important in dietary habit formation and should be encouraged by health professionals in their advice to families.

  20. Residual feed intake in beef cattle

    Directory of Open Access Journals (Sweden)

    J P.F. Arthur

    2008-07-01

    Full Text Available Providing feed is a major input cost in beef production, hence improvements in the efficiency of feed utilisation will reduce the cost of production. Residual feed intake (RFI is a measure of feed efficiency, and is defined as the difference between an animal's actual feed intake and its expected feed intake based on its size and growth. It is independent of the level of production, and the lower the value the more efficient the animal is. This paper examines the current state of knowledge on RFI. Available information indicates that postweaning RFI is moderately heritable, and that selection for low RFI will result in progeny that consume less feed for the same level of production as progeny of high RFI cattle. Under ad libitum feeding, RFI is phenotypically independent of growth traits. There is a weak genetic relationship between RFI and fatness but additional studies are needed to assess the magnitude of this relationship in different breeds, sexes, ages and feeding regimes. Residual feed intake is believed to represent inherent variation in basic metabolic processes which determine efficiency. Economic analyses of genetic improvement schemes that incorporate testing of individuals for RFI have yielded substantial economic benefits over and above existing schemes that do not include RFI testing. Selection for low RFI has an additional benefit of reducing greenhouse gas emissions by cattle.

    The food heritage which Americans enjoy today owes its great diversity to the influences of many ethnic groups--the native Indians, Franciscan friars in California, Mexican-Americans, the British, the French, the Creoles, and later, northern Europeans and those of Mediterranean stock. Geography and climate in different parts of our large country and religious beliefs have also played a part in the development of our present-day, varied cuisine. In our colonial and pioneer days, most people raised their own food, but as our nation has become industrialized and urbanized, we find that now only 7 per cent of our population produces the food for our entire nation, and our consumers generally buy their food in stores. Even as late as the beginning of the twentieth century, infant feeding practices could be considered unscientific and primitive. Only in recent years have knowledge of metabolism and the rapid increase in nutritional science permitted progress in infant feeding. Problems of feeding families remain, nevertheless--different than in the early days of our nation--and their solution challenges American ingenuity.

    A prospective study was conducted over a 2-year period to detect the effect of feeding practice, in particular the role of artificial milk formulae, in children admitted with hypernatraemic dehydration (serum sodium > or = 150 mmol/L) caused by acute gastro-enteritis, and to record morbidity and mortality in these patients. A control group was selected from infants and children admitted with gastro-enteritis but normal sodium levels. Sixty-seven children aged 18 days to 18 months (mean 6.9 months) were studied and represented 4.6% of all children admitted during the study with acute gastro-enteritis. Their mean serum sodium level was 161 mmol/L, the highest being 194 mmol/L. Twenty-four infants (36%) with hypernatraemic dehydration were on evaporated cow's milk powder compared with ten (15%) in the control group (p hypernatraemic infants (7.5%) were breastfed compared with 40 (60%) isonatraemic controls (p hypernatraemic group developed convulsions and two died. Hypernatraemic dehydration remains an important and serious complication in infants with gastro-enteritis in our area. Artificial milk feeding, particularly the use of evaporated cow's milk powder, is a predisposing factor for hypernatraemia in infantile gastro-enteritis. This study emphasises the importance of breast-feeding and the need to educate mothers to avoid giving evaporated cow's milk formulae to babies under 1 year of age if breast-feeding is not possible.

    BACKGROUND:The role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of acute pancreatitis has evolved over years since its introduction in 1968. Its importance in diagnosing the etiology of pancreatitis has steadily declined with the advent of less invasive diagnostic tools. The therapeutic implications of ERCP in acute pancreatitis are many fold and are directed towards management of known etiological factors or its related complications. This article highlights the current status of ERCP in acute pancreatitis. DATA SOURCES:An English literature search using PubMed database was conducted on ERCP in acute pancreatitis, the etiologies and complications of pancreatitis amenable to endotherapy and other related subjects, which were reviewed. RESULTS: ERCP serves as a primary therapeutic modality for management of biliary pancreatitis in speciifc situations, pancreatitis due to microlithiasis, speciifc types of sphincter of Oddi dysfunction, pancreas divisum, ascariasis and malignancy. In recurrent acute pancreatitis and smoldering pancreatitis it has a deifnite therapeutic utility. Complications of acute pancreatitis including pancreatic-duct disruptions or leaks, benign pancreatic-lfuid collections and pancreatic necrosis can be beneifcially dealt with. Intraductal ultrasound and pancreatoscopy during ERCP are useful in detecting pancreatic malignancy. CONCLUSIONS:The role of ERCP in acute pancreatitis is predominantly therapeutic and occasionally diagnostic. Its role in the management continues to evolve and advanced invasive procedures should be undertaken only in centers dedicated to pancreatic care.

  4. Chronic loss of melanin-concentrating hormone affects motivational aspects of feeding in the rat.

    Full Text Available Current epidemic obesity levels apply great medical and financial pressure to the strenuous economy of obesity-prone cultures, and neuropeptides involved in body weight regulation are regarded as attractive targets for a possible treatment of obesity in humans. The lateral hypothalamus and the nucleus accumbens shell (AcbSh form a hypothalamic-limbic neuropeptide feeding circuit mediated by Melanin-Concentrating Hormone (MCH. MCH promotes feeding behavior via MCH receptor-1 (MCH1R in the AcbSh, although this relationship has not been fully characterized. Given the AcbSh mediates reinforcing properties of food, we hypothesized that MCH modulates motivational aspects of feeding.Here we show that chronic loss of the rat MCH-precursor Pmch decreased food intake predominantly via a reduction in meal size during rat development and reduced high-fat food-reinforced operant responding in adult rats. Moreover, acute AcbSh administration of Neuropeptide-GE and Neuropeptide-EI (NEI, both additional neuropeptides derived from Pmch, or chronic intracerebroventricular infusion of NEI, did not affect feeding behavior in adult pmch(+/+ or pmch(-/- rats. However, acute administration of MCH to the AcbSh of adult pmch(-/- rats elevated feeding behavior towards wild type levels. Finally, adult pmch(-/- rats showed increased ex vivo electrically evoked dopamine release and increased limbic dopamine transporter levels, indicating that chronic loss of Pmch in the rat affects the limbic dopamine system.Our findings support the MCH-MCH1R system as an amplifier of consummatory behavior, confirming this system as a possible target for the treatment of obesity. We propose that MCH-mediated signaling in the AcbSh positively mediates motivational aspects of feeding behavior. Thereby it provides a crucial signal by which hypothalamic neural circuits control energy balance and guide limbic brain areas to enhance motivational or incentive-related aspects of food consumption.

    A multistressor study was conducted to investigate interactive effects of nutritional status and salinity on osmoregulation of juvenile white sturgeon. Our hypothesis was that lower nutritional status would decrease the salinity tolerance of juvenile white sturgeon. A four-week feed restriction (12.5%, 25%, 50%, 100% of optimum feeding rate: OFR defined as the rate (% body weight per day) at which growth is maximal) trial was performed, and relevant indices of nutritional status were measured. Following the trial, sturgeon were acutely exposed to various salinities (0, 8, 16, 24 ppt) for 120 h, and relevant osmoregulatory measurements were made at 12, 72, and 120 h post-salinity exposures. The feed-restriction trial resulted in a graded nutritional response with the most feed-restricted group (12.5% OFR) showing the lowest nutritional status. The salinity exposure trial showed clear evidence that lower nutritional status decreased the salinity tolerance of juvenile white sturgeon. Increasing salinities resulted in significant alterations in osmoregulatory indices of all feeding groups; however, a significantly slower acclimatory response to 24 ppt was detected in the most feed-restricted group compared to the non-feed-restricted group (100% OFR). Furthermore, evaluation of the effect of nutritional status on the relationship between osmoregulatory measurements and body size showed that there was a significant negative relationship between osmoregulatory performance and body size within the most feed-restricted group. This suggests that there is a certain body size range (200-300 g based on our finding) where juvenile white sturgeon can maximize osmoregulatory capacity at a salinity of 24 ppt. PMID:26123778

    The diagnosis of acute pancreatitis is based on clinical examination and basic laboratory tests. The main role of sonography in acute pancreatitis is to evaluate gallstones and small fluid collections. However, sonography is frequently difficult due to intestinal ileus related to pancreatitis. CT is indicated early in the clinical course of acute severe pancreatitis when the diagnosis is uncertain or when complications such as abscess, hemorrhage, or necrosis, are suspected. In addition, CT may be used to assess the prognosis and follow-up of patients. (authors). 20 refs., 12 figs., 4 tabs.

    The impact of the protein content of feed barley on the costs of feeding beef, dairy cattle, and swine in Montana is evaluated. A model of least-cost feed rations is constructed to analyze the marginal value of additional protein content in feed barley.

    Full Text Available Abstract Background Early enteral nutrition is recommended in cases of critical illness. It is unclear whether this recommendation is of most benefit to extremely ill patients. We aim to determine the association between illness severity and commencement of enteral feeding. Methods One hundred and eight critically ill patients were grouped as “less severe” and “more severe” for this cross-sectional, retrospective observational study. The cut off value was based on Acute Physiology and Chronic Health Evaluation II score 20. Patients who received enteral feeding within 48 h of medical intensive care unit (ICU admission were considered early feeding cases otherwise they were assessed as late feeding cases. Feeding complications (gastric retention/vomiting/diarrhea/gastrointestinal bleeding, length of ICU stay, length of hospital stay, ventilator-associated pneumonia, hospital mortality, nutritional intake, serum albumin, serum prealbumin, nitrogen balance (NB, and 24-h urinary urea nitrogen data were collected over 21 days. Results There were no differences in measured outcomes between early and late feedings for less severely ill patients. Among more severely ill patients, however, the early feeding group showed improved serum albumin (p = 0.036 and prealbumin (p = 0.014 but worsened NB (p = 0.01, more feeding complications (p = 0.005, and prolonged ICU stays (p = 0.005 compared to their late feeding counterparts. Conclusions There is a significant association between severity of illness and timing of enteral feeding initiation. In more severe illness, early feeding was associated with improved nutritional outcomes, while late feeding was associated with reduced feeding complications and length of ICU stay. However, the feeding complications of more severely ill early feeders can be handled without significantly affecting nutritional intake and there is no eventual difference in length of hospital stay or mortality

    A three-year-old male child presented with erythematous maculopapular nonpruritic generalized rash, poor feeding, vomiting, and cramping generalized abdominal pain. He was previously healthy and there was no family history of immunologic or other diseases. On examination he was afebrile, hemodynamically stable, with painful palpation of the right upper quadrant and positive Murphy's sign. Laboratory tests revealed elevated inflammatory markers, elevated aminotransferase activity, and features of cholestasis. Abdominal ultrasound showed gallbladder wall thickening of 8 mm with a positive sonographic Murphy's sign, without gallstones or pericholecystic fluid. Acute Alithiasic Cholecystitis (AAC) was diagnosed. Tests for underlying infectious causes were negative except positive blood specimen for Human Herpes Virus Type-6 (HHV-6) by polymerase chain reaction. With supportive therapy the child became progressively less symptomatic with gradual improvement. The child was discharged on the sixth day, asymptomatic and with improved analytic values. Two months later he had IgM negative and IgG positive antibodies (1/160) for HHV-6, which confirmed the diagnosis of previous infection. In a six-month follow-up period he remains asymptomatic. To the best of our knowledge, this represents the first case of AAC associated with HHV-6 infection. PMID:27200203

    On 25 January 2014, a 1 mo old female Amazonian manatee Trichechus inunguis calf weighing 12 kg was rescued by air transport in Guajará, Brazil, and transferred to Mamirauá Institute's Community-based Amazonian Manatee Rehabilitation Center. The calf presented piercing/cutting lesions on the back, neck, and head, in addition to dehydration and intermittent involuntary buoyancy. X-ray analysis revealed a large amount of gases in the gastrointestinal tract. Daily procedures included wound cleaning and dressing, clinical and laboratory monitoring, treatment for intestinal tympanism, and artificial feeding. Adaptation to the nursing formula included 2 kinds of whole milk. Up to 20 d post-rescue the calf presented appetite, was active, and gained weight progressively. Past this period the calf started losing weight and presented constant involuntary buoyancy and died after 41 d in rehabilitation. The major findings at necropsy were pneumatosis intestinalis in cecum and colon, pulmonary edema, and hepatomegaly. The microscopic examination revealed pyogranulomatous and necrohemohrragic colitis with multinucleated giant cells, acute multifocal lymphadenitis with lymphoid depletion in cortical and paramedullary regions of mesenteric lymph nodes, and diffuse severe acinar atrophy of the pancreas. Anaerobic cultures of fragments of cecum and colon revealed colonies genotyped as Clostridium perfringens type A. We speculate that compromised immunity, thermoregulatory failure, and intolerance to artificial diet may have been contributing factors to the infection, leading to enterotoxemia and death.

  10. Behavioral Change Strategies for Improving Complementary Feeding and Breastfeeding.

    Osendarp, Saskia J M; Roche, Marion L

    2016-01-01

    Improving infant and young child feeding (IYCF) practices, including breastfeeding and complementary feeding, has been identified as one of the most effective interventions to improve child survival, stunting and wasting. Evidence from randomized controlled trials suggests that effective promotion of breastfeeding and complementary feeding, with or without food provision, has the potential to improve IYCF practices and child nutrition. However, in many countries, breastfeeding practices and complementary feeding practices are still far from optimal. The lack of implementation of available, effective, affordable interventions in scale-up programs is in part attributed to a lack of innovative, creative and effective behavioral change strategies that enable and encourage caregivers. Successful behavioral change strategies should be based on a rigorous situational analysis and formative research, and the findings and insights of formative research should be used to further design interventions that address the identified barriers and enablers, to select delivery channels, and to formulate appropriate and effective messages. In addition, successful behavioral change interventions should a priori define and investigate the program impact pathway to target behavioral change and should assess intermediary behavioral changes and indicators to learn why the expected outcome was achieved or not achieved by testing the program theory. The design of behavioral change communication must be flexible and responsive to shifts in societies and contexts. Performance of adequate IYCF also requires investments to generate community demand through social mobilization, relevant media and existing support systems. Applying these principles has been shown to be effective in improving IYCF practices in Vietnam, Bangladesh and Ethiopia and is recommended to be adopted by other programs and countries in order to accelerate progress in improving child nutrition.

    2012-02-01

    Researchers use the Caregiver's Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits which are used in a substantial body of parenting literature and allow for direct comparison across studies on dimensions of demandingness and responsiveness.

    Corn milling byproducts are expected to increase dramatically in supply as the ethanol industry expands. Distillers grains, corn gluten feed, or a combination of both byproducts offer many feeding options when included in feedlot rations. These byproduct feeds may effectively improve cattle performance and operation profitability. When these byproducts are fed in feedlot diets, adjustments to grain processing method and roughage level may improve cattle performance. Innovative storage methods for wet byproducts and the use of dried byproducts offer small operations flexibility when using byproducts. As new byproducts are developed by ethanol plants, they should be evaluated with performance data to determine their product-specific feeding values. PMID:17606148

    Researchers use the Caregiver's Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits which are used in a substantial body of parenting literature and allow for direct comparison across studies on dimensions of demandingness and responsiveness. No national norms currently exist for the CFSQ. This paper establishes and recommends cutoff points most relevant for low-income, minority US samples that researchers and clinicians can use to assign parents to feeding styles. Median scores for five studies are examined and the average across these studies reported. PMID:22119478

  14. Improving feed slurry rheology by colloidal techniques

    1984-06-01

    Pacific Northwest Laboratory (PSN) has investigated three colloidal techniques in the laboratory to improve the sedimentation and flowability of Hanford simulated (nonradioactive) current acid waste (CAW) melter feed slurry: polymer-induced bridging flocculation; manipulating glass former (raw SiO/sub 2/ or frit) particle size; and alteration of nitric acid content. All three methods proved successful in improving the rheology of the simulated CAW feed. This initially had exhibited nearly worst-case flow and clogging properties, but was transformed into a flowable, resuspendable (nonclogging) feed. While each has advantages and disadvantages, the following three specific alternatives proved successful: addition of a polyelectrolyte in 2000 ppM concentration to feed slurry; substitution of a 49 wt % SiO/sub 2/ colloidal suspension (approx. 10-micron particle size) for the -325 mesh (less than or equal to 44-micron particle size) raw-chemical SiO/sub 2/; and increase of nitric acid content from the reference 1.06 M to optimum 1.35 M. The first method, polymer-induced bridging flocculation, results in a high sediment volume, nonclogging CAW feed. The second method, involving the use of colloidal silica particles results in a nonsedimenting feed that when left unagitated forms a gel. The third method, increase in feed acidity, results in a highly resuspendable (nonclogging) melter feed. Further research is therefore required to determine which of the three alternatives is the preferred method of achieving rheological control of CAW melter feeds.

    Tidal disruption events (TDEs) occur when a star, passing too close to a massive black hole, is ripped apart by tidal forces. A less dramatic event occurs if the star orbits just outside the tidal radius, resulting in a mild stripping of mass. Thus, if a star orbits a central black hole on one of these bound eccentric orbits, weaker outbursts will occur recurring every orbital period. Thanks to five Swift observations, we observed a recent flare from the close by (92 Mpc) galaxy IC 3599, where a possible TDE was already observed in December 1990 during the Rosat All-Sky Survey. By light curve modeling and spectral fitting, we account for all these events as the non-disruptive tidal stripping of a single star into a 9.5 yr highly eccentric bound orbit. This is the first example of periodic partial tidal disruptions, possibly spoon-feeding the central black hole.

    OBJECTIVE: The authors' goal was to determine whether early termination of breast-feeding contributes to later alcohol dependence, as proposed more than 200 years ago by the British physician Thomas Trotter. METHOD: In 1959-1961, a multiple-specialty group of physicians studied 9, 182 consecutive...... diagnosed as alcohol dependent at age 30, 13 (48%) came from the group weaned from the breast before the age of 3 weeks; only 33 (19%) of the 173 non-alcohol-dependent subjects came from the early weaning group. When challenged by other perinatal variables in a multiple regression analysis, early weaning...... significantly contributed to the prediction of the severity of alcoholism at age 30. CONCLUSIONS: The data support the hypothesis that early weaning may be associated with a greater risk of alcohol dependence later in life....

    Full Text Available To evaluate date stones as dietary component for broilers, two trials were carried out. In the first trial, Tunisian Deglet date stones were used and in the second one, stones were the waste product of an Italian distillery. One-day-old Arbor Acres chickens were cage reared and fed for 6 weeks on 4 experimental diets, which were formulated to be isonitrogenous and isocaloric and differed in cereal component (maize or low tannin sorghum and in inclusion level (0 or 10 % of ground date stones. Birds ' performances were slightly different in the two trials, but overall results indicate that date stones are suitable for use in broiler's feeding under such conditions.

    Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers.

  4. Acute lymphocytic Leukemia masquerading as acute osteomyelitis

    International Nuclear Information System (INIS)

    Two children each developed a focal destructive bone lesion accompanied by intermittent fever, swelling, tenderness and elevated ESR. Blood counts were normal; bone marrow aspiration showed acute leukemia. The bone lesions healed in both patients after anti-leukemic therapy. We suggest that the similar roentgenographic appearance of osteomyelitis, bone infarction and focal destructive lesions in leukemia probably reflects a common, basically ischemic process of bone.

    Full Text Available Appendicitis in leukemic patients is uncommon but associated with increased mortality. Additionally, leukemic cell infiltration of the appendix is extremely rare. While appendectomy is the treatment of choice for these patients, diagnosis and management of leukemia have a greater impact on remission and survival. A 59-year-old Caucasian female was admitted to the surgical service with acute right lower quadrant pain, nausea, and anorexia. She was noted to have leukocytosis, anemia, and thrombocytopenia. Abdominal imaging demonstrated appendicitis with retroperitoneal and mesenteric lymphadenopathy for which she underwent laparoscopic appendectomy. Peripheral smear, bone marrow biopsy, and surgical pathology of the appendix demonstrated acute myeloid leukemia (AML with nonsuppurative appendicitis. In the setting of AML, prior cases described the development of appendicitis with active chemotherapy. Of these cases, less than ten patients had leukemic infiltration of the appendix, leading to leukostasis and nonsuppurative appendicitis. Acute appendicitis with leukemic infiltration as the initial manifestation of AML has only been described in two other cases in the literature with an average associated morbidity of 32.6 days. The prompt management in this case of appendicitis and AML resulted in an overall survival of 185 days.

    2016-01-01

    Introduction Hepatic injury of varied aetiology may progress to Acute Liver Failure (ALF). Compromised microcirculation is thought to be a deciding factor of hepatic hypoxia may be involved in disease progression that needs early detection. Ischaemia markers like serum Ischaemia- modified albumin (IMA), ALT-LDH ratio and ALT-LDH index have been suggested for its detection at early stage. Aim To find out the association of Ischaemia markers like serum IMA, ALT-LDH ratio and ALT-LDH index in acute hepatic injury cases. Materials and Methods Forty one diagnosed acute liver injury cases of varied aetiology admitted in Department of Medicine, and Gastroenterology of SCB Medical College, Cuttack were enrolled in the study along with 30 age and sex matched healthy controls. Blood collected at time of admission and at time of discharge (1st day and 7th day) were evaluated for FPG, RFT, LFT, Serum Albumin along with serum LDH, IMA, PT-INR and platelet count. Result Serum bilirubin, hepatic enzymes, IMA, PT-INR was more markedly raised in cases than controls on the 1st day of admission. ALT-LDH ratio and index were significantly low in complicated cases. However, on responding to treatment the ALT-LDH index on 7th day registered a rise in comparison to the 1st day, while serum IMA revealed an insignificant decline showing improvement in hepatic hypoxia. ALT-LDH ratio remains more or less same on response to treatment. Conclusion Serum IMA and ALT-LDH Index reveals association with disease process in Acute Hepatic Injury cases both clinically and biochemically and can be used as supportive parameters for the diagnosis of disease process.

    Monitoring of feeding and rumination behaviour can provide useful information for dairy herd management. The feeding behaviour of dairy cows can be recorded by different techniques, such as video cameras, weighing troughs or chewing sensors. Among feeding characteristics, individual feed intake of cows is of utmost interest, but as weighing troughs have high space and cost requirements they are used primarily in research studies. The objective of the present study was to evaluate whether records on feeding time or chewing activity or a combination of both contain enough information to estimate feed intake with sufficient accuracy. Feed intake and feeding time per cow were recorded by means of weighing troughs. Concurrently, chewing activity of seven cows was recorded by MSR-ART pressure sensors during five to eight measuring days per cow. Feeding and chewing behaviour were evaluated in time slots (1 min) and additionally assigned to feeding bouts for further analysis. The 1 min time slots were classified into feeding/no feeding or chewing/no chewing by the two systems, and agreement was found in 92.2% of the records. On average, cows spent 270±39 min/day at the feeding troughs and chewed 262±48 min/day. The average fresh matter intake (FMI) was 49.6±5.1 kg/day. Feed intake was divided into 9.7 bouts/day during which cows fed in average 27.8±21.7 min/bout and chewed 27.0±23.1 min/bout. The correlation between FMI and feeding time was r=0.891 and between FMI and chewing time r=0.780 overall cows. Hence, both systems delivered suitable information for estimating feed intake.

    2016-10-01

    Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

    Jejunostomy feeding tubes provide surgeons with an excellent method for providing nutritional support, but there are several complications associated with a tube jejunostomy, including complications resulting from placement of the tube, mechanical problems related to the location or function and development of focally thickened small-bowel folds. A 76-year old man who presented with multiple medical diseases was admitted to our hospital due to aspiration pneumonia with acute respiratory failure and septic shock. He underwent exploratory laparotomy with feeding jejunostomy using a 14-French nasogastric tube for nutritional support. However, occlusion of the feeding tube was found 30- d after operation, and a rare complication of knot formation in the tube occurred after a new tube was replaced. On the following day, the tube was removed and replaced with a similar tube, which was placed into the jejunum for only 15 cm. The patient's feedings were maintained smoothly for two months. Knot formation in the feeding tube seems to be very rare. To our knowledge, this is the third case in the literature review. Its incidence is probably related to the length of the tube inserted into the lumen.

  17. Scientific Opinion on Ergot alkaloids in food and feed

    EFSA Panel on Contaminants in the Food Chain

    2012-07-01

    Full Text Available

    The European Food Safety Authority (EFSA was asked by the European Commission to deliver a scientific opinion on ergot alkaloids (EAs in food and feed. EAs are produced by several members within the fungal orders of Hypocreales and Eurotiales. In Europe, Claviceps purpurea is the most widespread Claviceps species within the Hypocreales. A total of 20 558 analytical results for EAs in 1 716 food, 496 feed and 67 unprocessed grain samples were considered in this opinion. Based on the EAs identified in sclerotia of C. purpurea, and recent literature data, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel based its risk assessment on the main C. purpurea EAs, namely ergometrine, ergotamine, ergosine, ergocristine, ergocryptine (which is a mixture of α- and β- isomers, ergocornine, and the corresponding –inine epimers. The CONTAM Panel performed estimates of both chronic and acute exposure for various age groups across European countries. A BMDL10 of 0.33 mg/kg b.w. per day was calculated for the incidence of tail muscular atrophy in a 13-week rat feeding study of ergotamine. This effect was considered representative of the vasoconstrictive effects of EAs and provided a suitable reference point for establishment of a group acute reference dose of 1 μg/kg body weight (b.w. and a group tolerable daily intake of 0.6 μg/kg b.w. per day. The Panel concluded that whilst the available data do not indicate a concern for any population subgroup, the dietary exposure estimates relate to a limited number of food groups and a possible unknown contribution from other foods cannot be discounted. Estimates of exposure for livestock based on example diets and levels of EAs in cereal grains reported suggest that under normal conditions the risk of toxicosis is low.

  6. Irradiation effect on animal feeds and feedstuffs

    International Nuclear Information System (INIS)

    Aiming to secure the safety of animal feeds and develop the new resources, the effect of γ-irradiation on disinfection and the changes in components were investigated. Salmonellae and coliforms contaminating in animal feeds and feedstuffs were eliminated by 0.5 -- 0.6 Mrad and 0.5 -- 0.8 Mrad, and osmophilic moulds were sterilized by 0.7 -- 0.75 Mrad. From these results, it is concluded that the dose for disinfection of animal feeds is 0.8 Mrad. The main components were hardly changed by irradiation up to 5 Mrad, and the component changes in irradiated samples could be suppressed during storage while the components in unirradiated samples were markedly changed with the growth of osmophilic moulds. Histamine and lysinoalanine, which may cause the feed poisoning, were never accumulated in feedstuffs by irradiation. The nutritional value of chick feeds was not changed by 1.0 Mrad irradiation. From these results, it is considered that no problem for wholesomeness of animal feeds occurs by irradiation. Therefore, the irradiation is effective for disinfection and keeping the nutritional value of animal feeds during storage. Irradiation promotes the recovery of proteins in the wastewater by coagulation of proteins and improves the property of coagulants due to the degradation of polysaccharides. These results indicate that irradiation is effective to develop the new resources for animal feeds. (author)

  7. Aggressive and acute periodontal diseases.

    2014-06-01

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects. Diagnostic methods for this disease, based on a specific microbiologic, immunologic or

    Alcoholic hepatitis is an acute form of alcoholic liver disease with variable severity that develops in patients who usually have a history of prolonged and recent alcohol abuse. The diagnosis is clinical and depends on history, physical examination, and laboratory derangements. Liver biopsy is diagnostic but not universally performed, and noninvasive diagnostic modalities are under development. Scoring systems are used to assess severity of disease, predict mortality, and guide decisions for initiation of specific therapies. The natural history and long-term outcomes of alcoholic hepatitis, including recurrence, progression to cirrhosis, and mortality, vary and depend partly on abstinence from alcohol use. PMID:27373612

    Acute heart failure (AHF) is a life threatening clinical syndrome with a progressively increasing incidence in general population. Turkey is a country with a high cardiovascular mortality and recent national statistics show that the population structure has turned to an 'aged' population.As a consequence, AHF has become one of the main reasons of admission to cardiology clinics. This consensus report summarizes clinical and prognostic classification of AHF, its worldwide and national epidemiology, diagnostic work-up, principles of approach in emergency department,intensive care unit and ward, treatment in different clinical scenarios and approach in special conditions and how to plan hospital discharge.

    The strong emphasis on feeding in Asian cultures may influence decisions for nasogastric (NG) tube feeding in geriatric inpatients. We evaluated the utility, complications, and opinions of caregivers toward NG tube feeding in an acute geriatric ward in a teaching hospital in Kuala Lumpur. Consecutive patients aged 65 years and older receiving NG tube feeding were included. Sociodemographic, clinical, and laboratory indices were recorded. Opinion on NG tube feeding were evaluated through face-to-face interviews with caregivers, recruited through convenience sampling. Of 432 patients admitted, 96 (22%), age ± standard deviation = 80.8 ± 7.4 years, received NG tube feeding. The complication and mortality rates were 69% and 38%, respectively. Diabetes (odds ratio [95% confidence interval] = 3.34 [1.07, 10.44], aspiration pneumonia (8.15 [2.43, 27.24]), impaired consciousness (3.13 [1.05, 9.36]), and albumin ≤26 g/dl (4.43 [1.46, 13.44]) were independent predictors of mortality. Other relatives were more likely than spouses (23.5 [3.59, 154.2]) and caregivers with tertiary education more likely than those with no formal education ( 18 [1.23, 262.7]) to agree to NG feeding. Sixty-four percent of caregivers felt NG tube feeding was appropriate at the end of life, mostly due to the fear of starvation. NG tube feeding is widely used in our setting, despite high complication and mortality rates, with likely influences from cultural emphasis on feeding.

  13. Nutrition, feeding, and behavior of fish.

    Nutrition and feeding influence growth, reproduction, and health of fish and their response to physiologic and environmental stressors and pathogens. The basics of fish metabolism are similar to those of warm-blooded animals in that they involve food intake, digestion, absorption, and transport of nutrients to the various tissues. Fish, however, being the most primitive form of vertebrates, possess some distinguishing features which will be discussed. Unlike warm-blooded animals, which are homoeothermic, fish are poikilothermic, so their body temperature and metabolic rate depends on the water temperature and this has practical implications for the nutrition, feeding and health of fish. Several behavioral responses have been linked to methods of feeding, feeding habits, frequency of feeding, mechanisms of food detection, and food preferences. Fish are also unique among vertebrates in their ability to absorb minerals not only from their diets but also from water through their gills and skin. PMID:19341962

    Successful feeding is critical to biomass utilization processes, but difficult due to the heterogeneity, physical properties and moisture content of the particles. The objectives of the present study were to find the mechanisms of blockage in screw feeding and to determine the effects of particle mean size (0.5-15 mm), size distribution, shape, moisture content (10-60%), density and compressibility on biomass particle feeding at room temperature. Wood pellets, sawdust, hog fuel and wood shavings were tested in a screw feeder/lock hopper system previously employed to feed sawdust into a pilot-scale circulating fluidized-bed gasifier. Experimental results showed that large particles, wide size distributions, large bulk densities and high moisture contents generally led to larger torque requirements for screw feeding. The ''choke section'' and seal plug play important roles in determining the torque requirements. (author)

    1998-01-01

    For array of "brick" configuration there are electrical and mechanical advantages to feed the antenna with a feed on a substrate perpendicular to the antenna substrate. Different techniques have been proposed for exciting patch antennas using such a feed structure.Rncently, an aperture-coupled dielectric resonator antenna using a perpendicular feed substrate has been demonstrated to have very good power coupling efficiency. For a two-dimensional rectangular array with tapered slot antenna elements, a power combining network on perpendicular substrate is generally required to couple power to or from the array. In this paper, we will describe two aperture-coupled techniques for coupling microwave power from a linearly tapered slot antenna (LTSA) to a microstrip feed on a perpendicular substrate. In addition, we will present measured results for return losses and radiation patterns.

    Full Text Available Introduction: Feed is a potential and major source for introducing Salmonella into the animal-derived food chain. This is given special attention in the European Union (EU efforts to minimize human food-borne Salmonella infections from animal-derived food. The objective of this study was to estimate the total extra cost for preventing Salmonella contamination of feed above those measures required to produce commercial feed according to EU regulation (EC No 183/2005. The study was carried out in Sweden, a country where Salmonella infections in food-producing animals from feed have largely been eliminated. Methods: On the initiative and leadership of the competent authority, the different steps of feed production associated with control of Salmonella contamination were identified. Representatives for the major feed producers operating in the Swedish market then independently estimated the annual mean costs during the years 2009 and 2010. The feed producers had no known incentives to underestimate the costs. Results and discussion: The total cost for achieving a Salmonella-safe compound feed, when such a control is established, was estimated at 1.8–2.3 € per tonne of feed. Of that cost, 25% relates to the prevention of Salmonella contaminated high-risk vegetable feed materials (mainly soybean meal and rapeseed meal from entering feed mills, and 75% for measures within the feed mills. Based on the feed formulations applied, those costs in relation to the farmers’ 2012 price for compound feed were almost equal for broilers and dairy cows (0.7%. Due to less use of protein concentrate to fatten pigs, the costs were lower (0.6%. These limited costs suggest that previous recommendations to enforce a Salmonella-negative policy for animal feed are realistic and economically feasible to prevent a dissemination of the pathogen to animal herds, their environment, and potentially to human food products.

    Full Text Available introduction. Natural breastfeeding is the only proper way to feed newborns and infants because it ensures their proper development. Breastfeeding enhances health and protects against the development of many diseases in childhood and adulthood. The primary benefits of breastfeeding include reduced incidences of infection in the respiratory system as well as a reduction in gastrointestinal and systemic infections. The benefits of breastfeeding also include decreased inflammation and improved immunity to disease in the infant. Further benefits of breastfeeding are reduced incidences of type 1 diabetes, Crohn’s disease, and rheumatoid arthritis. objective. The aim of the study was to assess the degree of knowledge on maternal breastfeeding among current expecting mothers. materials and method.

For 139 (93.88% of the surveyed women, breastfeeding was a priority regarding the health of the child. Respondents most often used professional literature in order to gain knowledge about breastfeeding (63.27%. The least popular way of acquiring knowledge was through the media (27.21%. conclusions. Analysis of the collected material on the surveyed women showed that women have a diverse range of knowledge about breastfeeding. Currently, breastfeeding is required to be promoted and supported by midwives, paediatricians and other health professionals.

    Human milk is considered as the gold standard for infant feeding. Breastfeeding advantages extend beyond the properties of human milk itself. A complex of nutritional, environmental, socioeconomic, psychological as well as genetic interactions establish a massive list of benefits of breastfeeding to the health outcomes of the breastfed infant and to the breastfeeding mother. For this reason, exclusive breastfeeding is recommended for about 6 months and should be continued as long as mutually desired by mother and child. The evidence in the literature on the effect of breastfeeding on health outcomes is based on observational studies due to the fact that it is unethical and practically impossible to randomize children to be breastfed or not. As such, multiple confounders cloud the evidence and one must base conclusions on the accumulating evidence when not contradictory and on the only intervention study, PROBIT (Promotion of Breastfeeding Intervention Trial). This review highlights some of the health outcomes related to breastfeeding such as the prevention of infections, the effect of breastfeeding on neurodevelopmental outcome, obesity, allergy and celiac disease. Available evidence as well as some of the contradictory results is discussed. PMID:27336781

    Lots of green house gas (CH4) was produced and emitted in the sewage feeding and treatment processes of waster treatment plant (WWTP). This work summarized the mechanism of CH4 production in wastewater anaerobic treatment and listed out kinds of methanogens. Simultaneous,the influence factors of CH4 production and emission were also discussed. In the sewage treatment process, the CH4 production was related with DO, pH,temperature,sludge loading rate,nitrite/nitrate concentration etc. ; CH4 emissions quantity in the non-aerated u-nits was determined by CH4 production and CH, solubility, while in the aerated units, the CH4 emissions quantity was determined by wastewater disturbance caused by mechanical stirring or aeration.%污水输送和污水处理过程中会有大量的CH4温室气体产生和排放.总结了污水厌氧生化处理过程中CH4产生的机制,列举了产甲烷菌的种类.同时,分析了在污水生化处理各单元CH4产生与排放的影响因素:污水处理过程中,DO、pH、温度、污泥负荷、硝酸盐浓度和亚硝酸盐浓度等因素会影响CH4的产生.在污水处理过程中的厌氧段,CH4的排放主要是与CH4产生量及CH4在污水中的溶解度有关;在好氧段,CH4的排放与机械搅拌或曝气作用对水流的扰动有关.

    Acute asthma is the third commonest cause of pediatric emergency visits at PGIMER. Typically, it presents with acute onset respiratory distress and wheeze in a patient with past or family history of similar episodes. The severity of the acute episode of asthma is judged clinically and categorized as mild, moderate and severe. The initial therapy consists of oxygen, inhaled beta-2 agonists (salbutamol or terbutaline), inhaled budesonide (three doses over 1 h, at 20 min interval) in all and ipratropium bromide and systemic steroids (hydrocortisone or methylprednisolone) in acute severe asthma. Other causes of acute onset wheeze and breathing difficulty such as pneumonia, foreign body, cardiac failure etc. should be ruled out with help of chest radiography and appropriate laboratory investigations in first time wheezers and those not responding to 1 h of inhaled therapy. In case of inadequate response or worsening, intravenous infusion of magnesium sulphate, terbutaline or aminophylline may be used. Magnesium sulphate is the safest and most effective alternative among these. Severe cases may need ICU care and rarely, ventilatory support. PMID:21769523

    Full Text Available La pancreatitis aguda es una patología frecuente y potencialmente grave en la que el manejo nutricional influye de manera importante en su desarrollo, de tal forma que se puede considerar un tratamiento específico en los casos graves. Éstos suponen aproximadamente el 20% de los pacientes y presentan una mortalidad entre el 8-39%. En los casos leves se suele proceder a un ingreso en dieta absoluta y posterior reintroducción progresiva de la dieta. Aunque se ha demostrado que una reintroducción temprana acorta la duración del ingreso, existe incertidumbre acerca del momento y del tipo de dieta idóneos. Las pancreatitis graves son estados hipercatabólicos que se presentan en pacientes que frecuentemente presentan déficits nutricionales basales. El soporte nutricional iniciado precozmente por vía enteral ha demostrado un beneficio significativo respecto a la vía parenteral en cuanto a tasa de infección, control de glucemia y mortalidad. Este beneficio puede relacionarse con una disminución de la traslocación bacteriana. Si bien tradicionalmente se ha empleado la vía nasoyeyunal, existen estudios que apoyan la vía nasogástrica, mucho más accesible. En el siguiente texto ofrecemos una revisión actualizada del manejo nutricional en la pancreatitis aguda, intentando responder de manera clara y con un enfoque práctico a las preguntas que más frecuentemente se presentan en el manejo de esta patología.Acute pancreatitis is a common and potentially severe disease where nutritional support does affect its development in a way it may be considered a treatment in severe cases.

    Between 2012 and 2014, 2528 feed ingredient and complete feed samples were collected from central China. Numbers of 2083, 255 and 190 samples were analysed for aflatoxin B1 (AFB1), zearalenone (ZEN) and deoxynivalenol (DON), respectively, by high-performance liquid chromatography in combination with UV or fluorescence detection. The incidence rates of AFB1, ZEN and DON contamination of feed ingredients and complete feeds were 33.9%, 90.2% and 77.4%, respectively. The percentage of positive samples for AFB1 ranged from 13.1% to 97.1%. Cottonseed meal presented the most serious contamination by AFB1. ZEN and DON contamination levels of feeds ranged from 50% to 100%, indicating serious contamination over the studied 3-year period. This study demonstrates that AFB1, ZEN and DON contamination of feeds in central China is serious and differs over the years. Feeds are mostly contaminated with ZEN, followed by DON and AFB1.

    2006-04-01

    It is now widely recognized that malnutrition can partly be attributed to caregiver-child interaction during feeding episodes. Current conceptual frameworks emphasize the importance of responsiveness (including active and social behaviour), psychomotor abilities of the child to self-feed, and a non-distracting feeding environment. The present observational study had three main objectives: (1) to define operationally key terms such as responsive and active feeding and observe their frequency in a rural Bangladesh sample; (2) to examine whether self-feeding, responsive and active behaviours of the mother and child varied with child's age and amounts eaten; and (3) to determine associations between mother and child behaviours. Fifty-four mother-child pairs were observed during one feeding episode and behaviours were coded for 5 categories, namely self-feeding, responsive, active, social and distracting behaviours. Children were between 8 and 24 months of age. Results indicated that the five behaviours could be observed and reliably coded. Two-thirds of mothers had an active feeding style but only a third were responsive; the two styles did not overlap. With older children, mothers encouraged more eating and more self-feeding, but children did not feed themselves more; instead older children were more negatively responsive (refusing offered food). Positively responsive mothers tended to have active children who explicitly signaled their desire for food or water, and who ate more mouthfuls of food. Positively active mothers adopted different strategies to encourage eating, such as verbally directing the child to eat, focusing, and temporarily diverting. These mothers tended to have children who were negatively responsive and refused food. Children accepted on average 5.31 mouthfuls of food and rejected 2.13. Mothers who used intrusively active strategies (e.g. force feeding) tended to have children who were both positively and negatively responsive, thus partially

    Full Text Available Purpose. To review scientific sources on the use of feed yeast preparations in feeding of sturgeon species (Acipenserinae. Findings. The review of scientific works demonstrated that feed yeast in the feeding of sturgeons have been used as a source of vitamins and complete protein, the nutritional value of which is significantly higher than in the proteins of plant origin and are similar to the proteins of animal origin. In addition, a unit of yeast protein mass is significantly lower than in the feeds of animal origin. Moreover, based on the content of B group vitamins, feed yeast produced from the grain-potato spent wash exceed fish meal and meat-and-bone meal. The article highlights the peculiarities of the technological process of the production of different feed yeast species, amino acid and fatty acid composition of their preparations, basic physical and chemical parameters of their composition. The examples of feed yeast formulas for sturgeon species based on feed yeast preparations are presented. It was shown that sturgeon species, especially on early stages of their ontogenesis, could effectively use the feed yeast nucleotides. Thus, the latters can be an effective substitute of live zooplanktonic organisms. While the production of some feed yeast preparations (paprin, eprin was stopped in 1990s due to a number of social-economic reasons, the works on the creation of their full analogues was continued later. Currently, the trends of the development of world aquaculture anticipates the return to the use of yeast in fish feeding. Therefore, the interest of the agrarians of Ukraine in yeast lately increased and their use in agricultural sector increased by 2-2.5 times. Practical value. The array of the summarized information will be important for scientists who study the peculiarities of feeding of sturgeon species, because the data about the use of yeast as sources of complete protein in fish feeds is important in a constant search for the

    Full Text Available There is no specific treatment for acute pancreatitis. Majority of patients with acute pancreatitis respond to medical therapy. Supportive measures and close observations represent the cornerstone of the medical therapy. Failure to respond to medical treatment may indicate choledocholithiasis or infected necrosis. Endoscopic papillotomy with stone retrieval is beneficial in patients with severe biliary pancreatitis. Image-guided fine needle aspiration and bacteriological examination of aspirate is reliable in detecting infection and deliniating causative pathogen. Surgical debridement is the method of choice for treatment of infected necrosis. In contrast, in pancreatic abscess, surgery is preserved for those, who do not respond to percutaneous drainage combined with antibiotics. The benefit of antisecretory and antiproteolytic agents is debatable. A combination of antioxidants, calcium channel antagonists and antibiotics may play a major role in the treatment of acute pancreatitis in the future.

    2012-01-01

    Full Text Available Introduction. Acute pancreatitis in children is mostly due to abdominal trauma, diseases or congenital anomalies of the biliary-pancreatic tree. Both exogenous and endogenous functions of the gland could be disturbed by various levels of damage. Clinical Finding and Diagnostics. Acute abdominal pain, gastrointestinal signs and general deterioration are the main clinical findings. The examination can be completed by blood and urine tests of amylase, electrolytes level, and the C-reactive protein. In addition to these tests, ultrasound, computed tomography and endoscopy are required as well. Therapeutic Methods. The therapy of choice is non-operative treatment using medicaments to control the pain, decrease the pancreatic activity and prevent further complications. If the conservative treatment fails, the surgical approach is necessary: drainage, resections, by-pass procedures, etc. Conclusion. Acute pancreatitis is a very serious disease in childhood. Clinical experience and rational approach are very important in the diagnostic and therapeutic methods.

    Barie, Philip S; Eachempati, Soumitra R

    2003-08-01

    Acute cholecystitis can develop without gallstones in critically ill or injured patients. However, the development of acute acalculous cholecystitis is not limited to surgical or injured patients, or even to the intensive care unit. Diabetes, malignant disease, abdominal vasculitis, congestive heart failure, cholesterol embolization, and shock or cardiac arrest have been associated with acute acalculous cholecystitis. Children may also be affected, especially after a viral illness. The pathogenesis of acute acalculous cholecystitis is a paradigm of complexity. Ischemia and reperfusion injury, or the effects of eicosanoid proinflammatory mediators, appear to be the central mechanisms, but bile stasis, opioid therapy, positive-pressure ventilation, and total parenteral nutrition have all been implicated. Ultrasound of the gallbladder is the most accurate diagnostic modality in the critically ill patient, with gallbladder wall thickness of 3.5 mm or greater and pericholecystic fluid being the two most reliable criteria. The historical treatment of choice for acute acalculous cholecystitis has been cholecystectomy, but percutaneous cholecystostomy is now the mainstay of therapy, controlling the disease in about 85% of patients. Rapid improvement can be expected when the procedure is performed properly. The mortality rates (historically about 30%) for percutaneous and open cholecystostomy appear to be similar, reflecting the severity of illness, but improved resuscitation and critical care may portend a decreased risk of death. Interval cholecystectomy is usually not indicated after acute acalculous cholecystitis in survivors; if the absence of gallstones is confirmed and the precipitating disorder has been controlled, the cholecystostomy tube can be pulled out after the patient has recovered.

However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

    Summary Background: Pancreatitis in the pediatric age group is not as common as in adults. Etiologies are various and differ from those in adults. Although infectious etiology accounts for a significant number of cases of pancreatitis, acute infection with Human Immunodeficiency Virus (HIV) was rarely reported as a possible etiology for acute pancreatitis in adults. Acute pancreatitis has never been reported as a presenting manifestation of acute HIV infection in children. Case Report: We des...

    Sixty-eight patients with acute acalculous cholecystitis were reviewed. The results of history and physical examinations were usually nondiagnostic. IDA cholescintigraphy (93 per cent accuracy rate) was the only reliable diagnostic modality. The results of oral cholecystography, intravenous cholangiography and ultrasonography were considerably less reliable. One-half of the patients had gangrenous cholecystitis. Cholecystectomy was the preferred operation with an over-all mortality of 9 per cent. IDA cholescintigraphy is an important new modality for the diagnosis of acute acalculous cholecystitis which, in the past, has often been difficult to diagnose.

    Full Text Available Congenital leukemia (CL is an extremely rare disorder in the newborn, significant proportion of which is of myeloid origin, primarily of M4 or M5 morphology. As compared to pediatric leukemia, CL is a more aggressive disease. Acute myeloid leukemia (AML-M7 or acute megakaryocytic leukemia is a rare type of AML with an incidence of 0.5 per million per year. Median age of presentation is 6 years, and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions.

  20. Acute myocardial infarct imaging

    International Nuclear Information System (INIS)

    A brief review is presented of radiopharmaceuticals used for imaging acute myocardial infarction and instrumentation using the rectilinear scanner and the scintillation camera. Clinical experience indicates that myocardial imaging with /sup 99 m/Tc pyrophosphate is a useful adjunct to the electrocardiogram and serum enzyme activity in managing patients with myocardial infarction. The technique allows rapid diagnosis, accurate localization, and an estimate of the size of acute infarcts. It can also be used to document infarct extension and in association with myocardial perfusion imaging can help differentiate fresh from old myocardial infarction
