The immune-modulating effects of viable Weissella cibaria JW15 on RAW 264.7 macrophage cells

The objective of this study is to investigate the immune-enhancing ability of viable and heat-killed Weissella cibaria JW15(JW15)isolated from Kimchi in RAW 264.7 macrophages.The immune effects were evaluated by measuring the production of NO,cytokines,inflammatory enzyme,and activation of NF-κB.Viable JW15 executed higher activity on stimulating the release of TNF-αas well as activating NF-κB compared to that of heatkilled JW15.Additionally,viable and heat-killed JW15 significantly increased the production of NO,IL-6 and TNF-αmore than that of Lactobacillus rhamnosus GG(LGG).Furthermore,viable JW15 induced higher production of i NOS compared with that of viable LGG.Collectively,our finding indicates that viable JW15 had similar,if not more,immune-enhancing activities as heat-killed JW15.In addition,viable JW15 had higher immune-enhancing activity than commercial strain LGG.Therefore,viable JW15 has the potential to be used as a functional food to improve the host immune response.

Clinical Study on the Treatment of Neonatal Jaundice with Lidan Tuihuang Formula Combined with Bifid Lriple Viable and Blue Ray Irradiation

OBJECTIVE: To observe the clinical efficacy of Lidan Tuihuang formula combined with Peifeikang and blue light irradiation in the treatment of neonatal jaundice. METHODS: a total of 140 cases of neonatal jaundice were randomly divided into the observation group and the control group, with 70 cases in each group. The control group was treated with blue light irradiation and oral Bifid Lriple Viable, on the basis of conventional clinical interventions. The observation group was treated with Lidan Tuihuang formula on the basis of the control group. After 7 days of treatment, the scores of clinical symptom(skin yellowness, reduced milk volume, constipation, abdominal distension) and level of serum bilirubin before and after treatment were compared between the two groups, and the adverse reactions and clinical recurrence of the 2 groups were statistically analyzed. RESULTS: After treatment, the effective rate was 94.3% in the observation group which was significantly higher than that in the control group(77.1%)(P < 0.05). The degree of yellowing of the skin, the reduction of the amount of milk, the concentration of constipation and the distension of bloating were all significantly reduced in the 2 groups after treatment(P < 0.05), and the improvement of the above indexes in the observation group was significantly better than that in the control group(P < 0.05). The level of serum bilirubin was significantly lower in the 2 groups after treatment and even for 2 weeks after treatment(P < 0.05). The improvement level of serum bilirubin in the observation group after treatment and even for 2 weeks after treatment were significantly better than that in the control group(P < 0.05). The recurrence rate in the observation group was 8.7%, which was significantly lower than that in the control group 22.2 %(P < 0.05); No serious adverse reactions occurred in both groups. CONCLUSION: The combination of Lidan Tuihuang Formular, Bifid Lriple Viable, blue light irradiation for neonatal jaundice can rapidly improve the clinical symptoms of children, reduce the level of serum bilirubin and shorten the treatment time, with no obvious adverse reactions and high clinical safety.

Study on the mechanism of Yinzhihuang granules, Blue light irradiation combined with Bifid Triple Viable Capsules for neonatal jaundice treatment

Objective:To observe the mechanism of Yinzhihuang granules, Blue light irradiation combined with Bifid Triple Viable Capsules for neonatal jaundice treatment and offer clinical help to neonatal jaundice treatment. Methods:80 children with neonatal jaundice were selected and randomly divided into groups:the observation group (40 children) and the control group (40 children). The patient in the control group were treated with blue light and the patients in the observation group were treated with Yinzhihuang granules, Blue light irradiation combined with Bifid Triple Viable Capsules. Biochemical parameters [TBA (total bile acid), TSB (serum total bilirubin), DB (Direct bilirubin) and TCB (Percutaneous jaundice index)], nerve factor [NSE (neuronspecific enolase), Aβ(βamyloid protein) and S100B (Astrocyte derived protein)] and myocardial enzyme spectrum [LDH (lactate dehydrogenase), CK (creatine kinase) and CK-MB (isoenzymes of creatine kinase)], liver function [ALT (Alanine aminotransferase) and AST (glutamic-oxalacetic transaminase)] and renal function (BUN and Cr) were detected and analyzed before and after treatment.

The Stability of Some Viable Stars and Electromagnetic Field

We examine the impact of electromagnetic field on the stability of compact stars corresponding to embedded class one metric using the concept of cracking. For this purpose, we develop the generalized hydrostatic equi- librium equation for charged perfect fluid distribution of compact stars and perturb it by means of local density perturbation scheme to check the stability of inner matter configuration. We investigate the cracking of Her X-I, PSR 1937＋21, PSR J 1614-2230, PSR J 0348＋0432 and B.X J 1856-37. We conclude that PSR J 0348＋0432 and RX J 1856-37 exhibit cracking when charge is introduced on these astrophysical objects.

Detection of Target Genes in Viable Bacteria and Extracellular DNA Using Loop-Mediated Isothermal Amplification Assay

When the loop-mediated isothermal amplification(LAMP)assay is used for detecting target genes,DNA extraction is unnecessary in many cases.Simple pretreatment(e.g.heating)is enough to obtain rather sensitive responses.Even test samples without any pretreatment can be used as template.This feature suggests that LAMP is superior to PCR in developing point-of-care test strategies.In this study,using Stx1 gene from E.coli as model,we verified that viable cells,dead cells and extracellular DNA could function as template in the LAMP assay.In the incubation at 63℃,viable bacteria in the LAMP reaction mixture lysed completely within 2 min,providing DNA template for nucleic acid amplification.The Stx1 gene in diluted culture medium,spiked tap water,spiked seawater and real seawater all could be detected,with or without the step of DNA extraction.We found that the complex substances in real sample(e.g.natural seawater)exhibited considerable inhibitory effect on the sensitivity of the LAMP assay.These outcomes are meaningful for building a point-of-care strategy by employing the LAMP assay for environmental monitoring,bio-resource surveys,food safety,etc.in particular those based on environmental DNA.

Mass Media and Urban Tribes, Analysis of Their Relations by Stafford Beer＇s Viable System Model

This paper discusses the relations between mass media and urban tribes, by Stafford Beer＇s viable system model （VSM）. During 1950-2010, the influence of media and advertising over individual decision-making processes has deepened of age range to which have targeted advertising and expanded for Western world, leading the culture diversity, naturally given, toward only one standardized culture prevailing nowadays. In the 1960s they were the women, then the young people during 1970s, and then children in the 1980s and during the 1990s over early childhood, when we learnt to speak （3 years old）, achieving brand loyalty among very young children and the brands of products for this age group. From this perspective, urban tribes have taken control of the lives of young people, offering a false freedom, at the moment of choosing ＂How to be yourself＂ from options given in the market as a ＂catalogue of predesigned identities＂. A phenomenon is so complex, so it requires a holistic framework able to make explicit its components and relations between them and the relationship with internal and external environment. In particular, the VSM provides a way to analyze communication＇s problems thus clarifying： how, when and where, repair and controlling into the organization, identifying strategies to improve decision-making. Given the recursive nature of the VSM, it is possible to navigate within the phenomenon, through different recursions＇ levels. It will help to define more assertive and effective policies by health authorities, education and government in general, and also help someone among young people to see themselves inside of a dynamic consumption and thus can leave the domain and enter into a recta-domain, with more wisdom and consciousness.

Viable Myocardium Impact on Left Ventricular Function after Late Revascularization of Infarct-related Artery in Acute Myocardial Infarction

Objectives The long-term benefit of late reperfusion of infarct-related artery （IRA） after acute myocardial infarction （AMI） is controversial, and the benefit mechanisms remain uncertain. Low dose dobutamine stress echocardiography （LDSE） can identify viable myocardium and predict improvement of wall motion after revascularization. Methods Sixtynine patients with first AMI who did not received early reperfusion therapy were studied by LDSE at 5 to 10 days after AMI. Wall motion abnormality and left ventricular size were measured at the same time. Successful PCI were done in all patients at 10 to 21 days after AMI onset. Patients were divided in two groups based on the presence or absence of viable myocardium. Echocardiography was repeated six months later. Results There were 157 motion abnormality segments. 89 segments （57%） were viable during LDSE. 26 patients （38%） with viability and 43 （62%） without. In viable group, left ventricular ejection fraction （LVEF） was increased （P 〈 0.05）, and left ventricular end systolic volume index （LVESVI） and wall motion score （WMS） were decreased （P 〈 0.05 and P 〈 0.01） significantly at 6 months compared with baseline. But in patients without viability, LVEF was decreased （P 〈 0.01）, and LVESVI and left ventricular end diastolic volume index （LVEDVI） were increased （P 〈 0.05） significantly after 6 months, and the WMS did not changed （P 〉 0.05 ）. LVEF increased （P 〈 0.05 ） and WMS decreased （P 〈 0.05） on LDSE during acute phase in patients with viability, but they were not changed in the nonviable group. Conclusions Late revascularization of IRA in patients with presence of viable myocardium after AMI is associated with long-term preservation left ventricular function and less ventricular remodeling. Improvement of left ventricular systolic function on LDSE indicates late phase recovery of left ventricular function after late revascularization.

A portable viable Salmonella detection device based on microfluidic chip and recombinase aided amplification

creening of foodborne pathogens is important to prevent contaminated foods from their supply chains.n this study, a portable detection device was developed for rapid, sensitive and simple detection of viable almonella using a finger-actuated microfluidic chip and an improved recombinase aided amplification (RAA) assay. Improved propidium monoazide(PMAxx) was combined with RAA to enable this device to distinguish viable bacteria from dead ones. The modification of PMAxx into dead bacteria, the magnetic xtraction of nucleic acids from viable bacteria and the RAA detection of extracted nucleic acids were performed using the microfluidic chip on its supporting device by finger press-release operations. The fluorescent signal resulting from RAA amplification of the nucleic acids was collected using a USB camera nd analyzed using a self-developed smartphone App to quantitatively determine the bacterial concenration. This device could detect Salmonella typhimurium in spiked chicken meats from 1.3 × 10^(2) CFU/m L o 1.3 × 10^(7) CFU/m L in 2 h with a lower detection limit of 130 CFU/m L, and has shown its potential for on-site detection of foodborne pathogens.

Remaking a connection:molecular players involved in post-injury synapse formation

Functional recovery from central nervous system(CNS)trauma depends not only on axon regeneration or compensatory sprouting of uninjured fibers but also on the ability of newly grown axons to establish functional synapses with appropriate targets.Although several studies have successfully promoted long-distance axonal regeneration in distinct CNS injury models,none of them have resulted in a viable therapeutic approach for patient recovery.A possible reason may be the lack of new synaptogenesis for reestablishing the circuitry lost after injury.Herein,we discuss how our understanding of the mechanisms that instruct synapse formation in the injured nervous system may contribute to the design of new strategies to promote functional restoration in traumatic CNS disorders.

Eikenella corrodens isolated from pleural effusion:A case report

BACKGROUND The bacterium Eikenella,classified as a gram-negative member of the phylum Proteobacteria,is distinguished by its rarity,corrosive nature,facultative anaerobic properties,and conditional pathogenicity.It represents the sole species within its genus-Eikenella corrodens(E.corrodens)-and can be found colonizing both human and animal oral and nasopharyngeal regions.Additionally,it occasionally inhabits the gastrointestinal or urogenital tracts.However,its slow growth rate can be attributed to its high nutritional requirements.However,there is an uneven distribution of construction and diagnostic capacity in China which poses undeniable challenges for the clinical examination and analysis of this case,especially in the basic hospitals.CASE SUMMARY Here we presented a case of empyema associated with E.corrodens infection in a 67-year-old male patient without any previous history of infectious diseases in our primary hospital in Dongguan district of China.The patient was admitted due to recurrent worsening cough,sputum production,and dyspnea for 3 d,which had persisted for over 20 years.Moreover,the patient experienced a onehour episode of unconsciousness.Upon admission,immediate comprehensive examinations were conducted on the patient which subsequently led to his admission to the intensive care unit.Meanwhile,the patient presented with drowsiness and profuse sweating along with bilateral conjunctival edema observed during initiation of non-invasive ventilation,suggesting empyema.A significant amount of coffee-colored malodorous pleural fluid was drained during the procedure above and sent to the laboratory department for inspection.Finally,laboratory culture results confirmed the presence of E.corrodens infection in the pleural fluid sample.The patient received antimicrobial therapy until died on day 22 in the hospital.CONCLUSION In this report,we presented a case of empyema associated with E.corrodens infection.Multiple courses of morphological examination,viable culture analysis,and biochemical identification revealed its difficulties in detecting distinctive characteristics,as well as a detection model worth promoting.It’s just that there were still certain deficiencies in terms of morphological assessment,biochemical identification,and drug susceptibility testing.

Aiming Far Beyond the Moon--The Third Plenary Session highlights science and technological development

Change is the Chinese moon goddess.Named after her,the Chang'e-6 lunar module returned to Earth this June carrying 1,935.3grams of rocks and dust from the far side of the moon.China's lunar program began as recently as 2007 when Chang'e-I was placed in orbit to create a high resolution 3-D map of the moon's surface.As such,it illustrates China's enviable ability to concentrate its efforts on major tasks.This ability,as Chinese President Xi Jinping has suggested,is one of the major advantages of China's socialist system.

Feature extraction method of hyperspectral scattering images for prediction of total viable count in pork meat

This study aimed to investigate the capabilities of hyperspectral scattering imaging in tandem with Gaussian function,Exponential function and Lorentzian function for rapid and nondestructive determination of total viable count(TVC)in pork meat.Two batches of fresh pork meat was purchased from a local market and stored at 10°C for 1-9 d.Totally 60 samples were used,and several samples were taken out randomly for hyperspectral scattering imaging and conventional microbiological tests on each day of the experiments.The functions of Gaussian,Exponential and Lorentzian were employed to model the hyperspectral scattering profiles of pork meat,and good fitting results were obtained by all three functions between 455 nm and 1000 nm.The Lorentzian function performed best for fitting the hyperspectral scattering profiles of pork meat compared with other functions.Both principal component regression(PCR)and partial least squares regression(PLSR)methods were performed to establish the prediction models.Among all the developed models,the models developed using parameters CE(scattering width parameter of Exponential function)and CL(scattering width parameter of Lorentzian function)by PLSR method gave superior results for predicting pork meat TVC,with RV and RMSEV of 0.92,0.59 log CFU/g,and 0.91,0.61 log CFU/g,respectively.In addition,based on the improved hyperspectral scattering system,parameter c which represented the scattering widths in all three functions gave more accurate prediction results,regardless of the modeling methods(PCR or PLSR).The obtained results demonstrated that hyperspectral scattering imaging combined with the presented data analysis algorithm can be a powerful tool for evaluating the microbial safety of meat in the future.

Detection of viable myocardium by low dose of dobutamine cine MR imaging in miniswine

Objective To evaluate the diagnostic value of dobutamine stress magnetic resonance imaging (MRI) for myocardial viability.Methods Ten male miniswines underwent left ventriculography and coronary angiography, followed by stenosis of the left circumflex coronary artery (LCX) using ameroid constrictor. More than one month later, left ventriculography and coronary angiography were performed again, followed by cine-MRI at rest and during stress with incremental dose of dobutamine 5 -20 μg·kg-1·min-1. Traditional and/or breath-hold cine-MRI were used to evaluate regional left ventricular wall motion, corresponding to basal, midventricular and apical short-axis tomograms. Regional wall motion score index (WMSI) was calculated. The miniswines were finally sacrificed for pathological examination. Triphenyl tetrazolium chloride ( TTC) delineated myocardial infarction. Microscopy was used to identify myocardial cellular changes.Results One pig died, one pig suffered from aneurysm and another showed no negative findings. The other seven pigs were found with hypokinetic (n = 4) or akinetic (n = 3) myocardial regions related to stenosed LCX. Their mean WMSI at rest for the lateral and posteroinferior walls (ischemic regions) of the left ventricle was 2. 27±0.32, as compared with 1. 00±0. 00 ( P < 0. 01) for the corresponding nonischemic anteroseptal regions. Further, the mean WMSI for the ischemic regions was 2. 27±0. 32 at rest compared with 1. 40±0. 39(P<0. 01) at the dose of dobutamine 5 μg·kg-1 ·min-1. However, the mean WMSI at the doses of dobutamine 10 and 20 μg·kg-1·min-1 were 1. 70±0. 76 and 1. 75±0. 83, respectively, with no significant difference as compared with the mean WSCI at rest (P>0. 05). The pathologic examination showed viable myocardium at the ischemic regions.Conclusion Low-dose dobutamine (5μg·kg-1·min-1) recovers hypokinetic or akinetic myocardial regions, and dobutamine stress MRI can be used to detect myocardial viability.

Effects of Late Reperfusion on Left Ventricular Function and Its Relationship With Viable Myocardium After Acute Myocardial Infarction in Patients With or Without Diabetes

Objectives To compare the different effects of late successful reperfusion with PCI on left ventricular function and its relationship with viable myocardium after acute anterior wall myocardial infarction in patients with or without diabetes. Methods A total of 125 consecutive subjects with acute anterior wall myocardial infarction were selected, and divided into diabetes mellitus （DM） group （ n = 43） and Non-DM group （ n = 82） according to WHO diabetes diagnosis criteria. All patients received successful PCI at 12 ± 8 days from onset. Ischemic viable myocardium was detected with low-dose dobutamine echocardiography, and left ventricular function and wall motion abnormality were also assessed with echocardiography before PCI. The data of clinical manifestations and angiograms before and after PCI were analyzed. Levels of creatinine kinase-MB （CK-MB）, and troponin T （TnT） before PCI, 6 hours and 24 hours after PCI were assessed. All patients received clinic and echocardiography follow-up for 6 months. Results Higher rate of TIMI 2 flow, and lower rate of TIMI 3 flow in DM group were demonstrated immediately after PCI, and the rate of serum CK-MB and/or TnT levels were higher in DM group, compared with Non-DM group（P 〈 0.05）. 63% of DM patients and 56% of non-DM patients had viable myocardium before PCI（ P 〉 0. 05）. There were no significant differences of left ventricular ejection fraction （LVEF）, left ventricular end diastolic volume index （LVEDVI）, left ventricular end systolic volume index （LVESVI）, and wall motion score （WMS） between two groups at baseline before PCI（P 〉 0.05）. After six months, WMS was decreased and LVEF was increased in Non-DM group, but the WMS and the LVEF did not changed, and the LVEDVI was increased in DM group compared with baseline; the LVEDVI, LVESVI, LVEF, and WMS were significantly different between two groups （P 〈 0.05 or P 〈 0. 01 ）. Conclusions Compared with non-diabetics, delayed successful revascularization with PCI in diabetics patient with acute myocardial infarction has less benefitial effect on the improvement of late phase left ventricular function, and it may be because the insufficient reperfusion or reperfusion injury to myocardium but not the viable myocardium contributing to the poor result. （S Chin J Cardiol 2009; 10（4） ： 196 -203）
