4Standardizing a simpler, more sensitive and accurate tail bleeding assay in mice显示文摘AIM: To optimize the experimental protocols for a simple, sensitive and accurate bleeding assay.METHODS: Bleeding assay was performed in mice by tail tip amputation, immersing the tail in saline at 37 ℃, continuously monitoring bleeding patterns and measuring bleeding volume from changes in the body weight. Sensitivity and extent of variation of bleeding time and bleeding volume were compared in mice treated with the P2 Y receptor inhibitor prasugrel at various doses or in mice deficient of Fc Rγ, a signaling protein of the glycoprotein VI receptor.RESULTS: We described details of the bleeding assay with the aim of standardizing this commonly used assay. The bleeding assay detailed here was simple to operate and permitted continuous monitoring of bleedingpattern and detection of re-bleeding. We also reported a simple and accurate way of quantifying bleeding volume from changes in the body weight, which correlated well with chemical assay of hemoglobin levels(r2 = 0.990, P < 0.0001). We determined by tail bleeding assay the dose-effect relation of the anti-platelet drug prasugrel from 0.015 to 5 mg/kg. Our results showed that the correlation of bleeding time and volume was unsatisfactory and that compared with the bleeding time, bleeding volume was more sensitive in detecting a partial inhibition of platelet's haemostatic activity(P < 0.01). Similarly, in mice with genetic disruption of Fc Rγ as a signaling molecule of P-selectin glycoprotein ligand-1 leading to platelet dysfunction, both increased bleeding volume and repeated bleeding pattern defined the phenotype of the knockout mice better than that of a prolonged bleeding time.CONCLUSION: Determination of bleeding pattern and bleeding volume, in addition to bleeding time, improved the sensitivity and accuracy of this assay, particularly when platelet function is partially inhibited.Yang Liu Nicole L Jennings Anthony M Dart Xiao-Jun Du 2012World Journal of Experimental Medicine2012,2,2:6

6Plasma and platelet serotonin levels in patients with liver cirrhosis显示文摘AIM: To analyze the relationship between plasma and platelet serotonin levels and the degree of liver insufficiency. METHODS: The prospective study included 30 patients with liver cirrhosis and 30 healthy controls. The degree of liver failure was assessed according to the Child-Pugh classification. Platelet and platelet poor plasma serotonin levels were determined. RESULTS: The mean plasma serotonin level was higher in liver cirrhosis patients than in healthy subjects (215.0 ± 26.1 vs 63.1 ± 18.1 nmol/L; P < 0.0001). The mean platelet serotonin content was not significantly different in patients with liver cirrhosis compared with healthy individuals (4.8 ± 0.6; 4.2 ± 0.3 nmol/platelet; P > 0.05). Plasma serotonin levels were significantly higher in Child- Pugh grade A/B than in grade C patients (246.8 ± 35.0 vs 132.3 ± 30.7 nmol/L; P < 0.05). However, platelet serotonin content was not significantly different between Child-Pugh grade C and grade A/B (4.6 ± 0.7 vs 5.2 ± 0.8 nmol/platelet; P > 0.05). CONCLUSION: Plasma serotonin levels are significantly higher in patients with cirrhosis than in the controls and represent the degree of liver insufficiency. In addition, platelet poor plasma serotonin estimation is a better marker for liver insufficiency than platelet serotonin content.■or■e M ulafi Duko S Mirkovi Miodrag D Vukevi Jelena S Rudi 2007World Journal of Gastroenterology2007,13,43:5

8Assessing crop water stress of winter wheat by thermography under different irrigation regimes in North China Plain显示文摘Thermal imaging can be used as an indicator of water stress due to the closure of stomatal aperture.In this paper,we analyzed the robustness and sensitivity of thermography of winter wheat in the North China Plain.The seasonal and diurnal variations of Crop Water Stress Index(CWSI)were evaluated.Five treatments were applied by means of irrigation,with plots receiving 100%of ETo(DI),50%(D50),16%(D16)and no irrigation(NI).A high correlation was found between stomatal conductance(gs)and CWSI,depending on the phenological stage of the crop with R2=0.44 at pre-heading stage and R2=0.77 at post-heading stage.In addition,a high correlation between yield and CWSI at different growth stages indicates that thermography can predict yield.Hourly measurements of canopy temperature were taken to study the effect of the time of day on image acquisition and it was found that midday was the most appropriate time.These results should assist in designing precision irrigation scheduling for setting the threshold values.Shamaila Zia Du Wenyong Wolfram Spreer Klaus Spohrer He Xiongkui Joachim Müller 2012International Journal of Agricultural and Biological Engineering2012,5,3:4

10Utilization of Thermal Infrared Image for Inversion of Winter Wheat Yield and Biomass显示文摘The present paper utilizes thermal infrared image for inversion of winter wheat yield and biomass with different technology of irrigation(drip irrigation,sprinkler irrigation,flood irrigation).It is the first time that thermal infrared image is used for predicting the winter wheat yield and biomass.The temperature of crop and background was measured by thermal infrared image.It is necessary to get the crop background separation index(CBSIL,CBSIH),which can be used for distinguishing the crop value from the image.CBSIL and CBSIH(the temperature when the leaves are wet adequately;the temperature when the stomata of leaf is closed completely) are the threshold values.The temperature of crop ranged from CBSIL to CBSIH.Then the ICWSI was calculated based on relevant theoretical method.The value of stomata leaf has strong negative correlation with ICWSI proving the reliable value of ICWSI.In order to construct the high accuracy simulation model,the samples were divided into two parts.One was used for constructing the simulation model,the other for checking the accuracy of the model.Such result of the model was concluded as:(1) As for the simulation model of soil moisture,the correlation coefficient(R2) is larger than 0.887 6,the average of relative error(Er) ranges from 13.33% to 16.88%;(2) As for the simulation model of winter wheat yield,drip irrigation(0.887 6,16.89%,-0.12),sprinkler irrigation(0.970 0,14.85%,-0.12),flood irrigation(0.969 0,18.87%,0.18),with the values of R2,Er and CRM listed in the parentheses followed by the individual term.(3) As for winter wheat biomass,drip irrigation(0.980 0,13.70%,0.13),sprinkler irrigation(0.95,13.15%,-0.14),flood irrigation(0.970 0,14.48%,-0.13),and the values in the parentheses are demonstrated the same as above.Both the CRM and Er are shown to be very low values,which points to the accuracy and reliability of the model investigated.The accuracy of model is high and reliable.The results indicated that thermal infrared image can be used potentially for inversion of winter wheat yield and biomass.DU Wen-yong ZHANG Lu-da HU Zhen-fang Shamaila Z ZENG Ai-jun SONG Jian-li LIU Ya-jia Wolfram S Joachim M HE Xiong-kui 2011光谱学与光谱分析2011,31,6:3
11Neonatal vitamin A injection promotes cattle muscle growth and increases oxidative muscle fibers显示文摘Background: Vitamin A and its metabolite,retinoic acid(RA),are important regulators of cell differentiation and organ morphogenesis.Its impact on beef cattle muscle growth remains undefined.Method: Angus steer calves were administrated with 0(control) or 150,000 IU vitamin A(retinyl palmitate in glycerol,i.m.) per calf at birth and 1 month of age.At 2 months of age,a biopsy of the Biceps femoris muscle was obtained to analyze the immediate effects of vitamin A injection on myogenic capacity of muscle cells.The resulting steers were harvested at 14 months of age.Results: Vitamin A administration increased cattle growth at 2 months.At 2 months of age,Vitamin A increased PAX7 positive satellite cells and the expression of myogenic marker genes including PAX7,MYF5,MYOD and MYOG.Muscle derived mononuclear cells were further isolated and induced myogenesis in vitro.More myotubes and a higher degree of myogenesis was observed in vitamin A groups.Consistently,vitamin A increased Latissimus dorsi(LD) muscle fiber size at harvest.In addition,vitamin A increased the ratio of oxidative type I and type IIA fibers and reduced the glycolic type IIX fibers.Furthermore,we found that RA,a key bioactive metabolite of vitamin A,activated PPARGC1 A promoter,which explains the upregulated expression of PPARGC1 A in skeletal muscle.Conclusion: Vitamin A administration to neonatal calves enhanced postnatal muscle growth by promoting myogenesis and increasing satellite cell density,accompanied with a shift to oxidative muscle fibers.Bo Wang Wei Nie Xing Fu Jeanene M de Avila Yannan Ma Mei-Jun Zhu Martin Maquivar Steven M Parish Jan R Busboom Mark L Nelson Min Du 2019Journal of Animal Science and Biotechnology2019,10,1:3
12Rates and risk factors for suicidal ideation,suicide attempts and suicide deaths in persons with HIV:a systematic review and meta-analysis显示文摘Background People living with HIV/AIDS(PLWHA)must contend with a significant burden of disease.However,current studies of this demographic have yielded wide variations in the incidence of suicidality(defined as suicidal ideation,suicide attempt and suicide deaths).Aims This systematic review and meta-analysis aimed to assess the lifetime incidence and prevalence of suicidality in PLWHA.Methods Publications were identified from PubMed(MEDLINE),SCOPUS,OVID(MEDLINE),Joanna Briggs Institute EBP and Cochrane Library databases(from inception to before 1 February 2020).The search strategy included a combination of Medical Subject Headings associated with suicide and HIV.Researchers independently screened records,extracted outcome measures and assessed study quality.Data were pooled using a random-effects model.Subgroup and meta-regression analyses were conducted to explore the associated risk factors and to identify the sources of heterogeneity.Main outcomes were lifetime incidence of suicide completion and lifetime incidence and prevalence of suicidal ideation and suicide attempt.Results A total of 185199 PLWHA were identified from 40 studies(12 cohorts,27 cross-sectional and 1 nested case-control).The overall incidence of suicide completion in PLWHA was 10.2/1000 persons(95%CI:4.5 to 23.1),translating to 100-fold higher suicide deaths than the global general population rate of 0.11/1000 persons.The lifetime prevalence of suicide attempts was 158.3/1000 persons(95%CI:106.9 to 228.2)and of suicidal ideation was 228.3/1000 persons(95%CI:150.8 to 330.1).Meta-regression revealed that for every 10-percentage point increase in the proportion of people living with HIV with advanced disease(AIDS),the risk of suicide completion increased by 34 per 1000 persons.The quality of evidence by Grading of Recommendations,Assessment,Development and Evaluations for the suicide deaths was graded as‘moderate’quality.Conclusions The risk of suicide death is 100-fold higher in people living with HIV than in the general population.Lifetime incidence of suicidal ideation and attempts are substantially high.Suicide risk assessments should be a priority in PLWHA,especially for those with more advanced disease.Matt Pelton Matt Ciarletta Holly Wisnousky Nicholas Lazzara Monica Manglani Djibril M Ba Vernon M Chinchillli Ping Du Anna E Ssentongo Paddy Ssentongo 2021General Psychiatry2021,34,2:3
13Non-invasive water status detection in grapevine(Vitis vinifera L.)by thermography显示文摘Grapevines are preferentially grown under mild to moderate water stress conditions to achieve the best compromise between wine quality and quantity.Water status detection for advanced irrigation scheduling is frequently done by predawn leaf water potential(ΨPD)or leaf stomata conductance(gL)measurements.However,these measurements are time and labor consuming.Therefore,the use of infrared thermography(IRT)opens up the possibility to study large population of leaves and to give an overview on the stomatal variation and their dynamics.In the present study IRT was used to identify water stress of potted grapevines.In order to define the sensitivity of IRT measurements to water stress,the IRT-based water status information were compared with simultaneously measuredΨPD and gL data.Correlations between IRT-based CWSI data on the one hand and gL andΨPD on the other showed the potential of IRT for water stress detection.However,the CWSI calculation procedure is laborious and the sensitivity of CWSI for water stress detection still needs to be improved.Therefore,further improvements are necessary in order to apply remote IRT-based systems for irrigation scheduling in the field.Shamaila Zia Klaus Spohrer Nikolaus Merkt Du Wenyong Xiongkui He Joachim Müller 2009International Journal of Agricultural and Biological Engineering2009,2,4:3
14Monitoring physiological responses to water stress in two maize varieties by infrared thermography显示文摘Water stress is one of the main causes of yield reductions in crops,especially in arid and semi-arid regions where the water supply is limited.Plant water status is frequently assessed by pre-dawn leaf water potential(ΨPD)or leaf stomata conductance(gL)measurements,in support of advanced irrigation scheduling.However,both methods are time and labour consuming.A non-invasive approach to water status detection is the use of infrared thermography(IRT).This experiment was conducted in a greenhouse on two potted maize varieties under irrigated and non-irrigated conditions,and the measurements began when the crop had reached its twelve leaf stage.In order to establish the IRT measurements for detecting the water status of maize,an IRT-based crop water stress index(CWSI)was calculated and compared with simultaneously measuredΨPD and gL data.Good correlations were found between CWSI and gL data(r2=0.71&0.81),as well between CWSI andΨPD data(r2=0.53&0.81).These results highlight the appropriateness of infrared thermal imagery to detect and differentiate between the crop water statuses of different genotypes.Shamaila Zia Klaus Sophrer Du Wenyong Wolfram Spreer Giuseppe Romano He Xiongkui Joachim Müller 2011International Journal of Agricultural and Biological Engineering2011,4,3:3
