Magnesium is a divalent cation involved in more than 300 metabolic processes. Magnesium acts as an intracellular regulator of most energy-demanding pathways. Clinical investigation in the human medical field has determined risk factors for hypomagnesemia and its relationship to a number of disease processes. Experimental studies have established the effects of hypomagnesemia in dogs, but little is known of its prevalence, risk factors, or clinical associations in a hospital population of dogs. To study the prevalence, risk factors, and clinical associations of hypomagnesemia in dogs, a retrospective cross-sectional study of dogs admitted to the University of Minnesota Veterinary Teaching Hospital over a 2.5-year period was undertaken. The prevalence of hypomagnesemia in the study population was 6.1% (188 of 3,102 dogs). Using both categorical and continuous variables in a univariate analysis, significant associations with hypomagnesemia were identified and used to construct a multivariate analysis of the relative risk of hypomagnesemia. Results from evaluation of 3,102 dogs indicate that the most significant predictors of hypomagnesemia were albumin ( P ≤ .0001; odds ratio [OR] = 0.2), potassium ( P ≤ .0001; OR = 0.5), total CO₂ ( P ≤.05; OR = 0.9), and blood urea nitrogen concentrations ( P < .0001; OR = 0.9), a diagnosis of cardiovascular disease ( P < .02; OR = 1.9); and being a Collie ( P < .02; OR = 3.9) or German Shepherd Dog ( P < .002; OR = 2.2). These results can be used to better understand and predict hypomagnesemia in dogs.  相似文献

Full‐length cloning and phylogenetic analyses of translationally controlled tumour protein and ferritin genes from the Indian white prawn,Fenneropenaeus indicus (H. Milne Edwards)

Elucidation, through molecular analyses, of bacterial afflictions in commercially important aquaculture‐reared shrimps is pivotal for the prevention and/or control of disease outbreaks. In this study, we examined the phylogenetic relatedness and compared the possible immune‐related functional roles of both translationally controlled tumour protein (TCTP) and ferritin genes with previous studies. Both TCTP and ferritin genes were substantially upregulated in the Indian white prawn, Fenneropenaeus indicus (H. Milne Edwards), post‐larvae following bath challenge with the virulent strain of bacteria, Vibrio harveyi D3. Full‐length cloning of these genes by rapid amplification of complementary DNA ends ‐polymerase chain reaction (RACE‐PCR) yielded 727‐base pair (bp)‐long TCTP and 1212‐bp‐long ferritin gene sequences. Their open reading frames (ORFs) were 507 and 510 bp, respectively. The TCTP‐ORF coded for 168 amino acids with three substitutions at positions 37, 141, 155, and the ferritin ORF coded for 170 amino acids with no species‐specific substitutions. Phylogenetic analysis suggested the closest relatedness of both TCTP and ferritin from F. indicus to Chinese white prawn, Fenneropenaeus chinensis (Osbeck). In addition to reporting the full‐length sequences of these immune‐relevant genes, this study highlighted their conserved natures, which perhaps make them important defence‐related proteins in the innate immune system of F. indicus.  相似文献   

Effects of processing on immunoreactivity of cashew nut (Anacardium occidentale L.) seed flour proteins     

Venkatachalam M  Monaghan EK  Kshirsagar HH  Robotham JM  O'Donnell SE  Gerber MS  Roux KH  Sathe SK 《Journal of agricultural and food chemistry》2008,56(19):8998-9005

Cashew nut seeds were subjected to processing including autoclaving (121 degrees C for 5, 10, 20, and 30 min), blanching (100 degrees C for 1, 4, 7, and 10 min), microwave heating (1 and 2 min each at 500 and 1000 W), dry roasting (140 degrees C for 20 and 30 min; 170 degrees C for 15 and 20 min; and 200 degrees C for 10 and 15 min), gamma-irradiation (1, 5, 10, and 25 kGy), and pH (1, 3, 5, 7, 9, 11, and 13). Proteins from unprocessed and processed cashew nut seeds were probed for stability using anti-Ana o 2 rabbit polyclonal antibodies and mouse monoclonal antibodies directed against Ana o 1, Ana o 2, and Ana o 3 as detection agents. Results indicate that Ana o 1, Ana o 2, and Ana o 3 are stable regardless of the processing method to which the nut seeds are subjected.  相似文献   

Akt/FOXO3a/SIRT1-mediated cardioprotection by n-tyrosol against ischemic stress in rat in vivo model of myocardial infarction: switching gears toward survival and longevity     

Samuel SM  Thirunavukkarasu M  Penumathsa SV  Paul D  Maulik N 《Journal of agricultural and food chemistry》2008,56(20):9692-9698

Moderate consumption of wine has been associated with decreased risk of cardiovascular events. Recently we have shown that white wine is equally as cardioprotective as red wine. However, unlike resveratrol (polyphenol in red wine), the white wine component, n-tyrosol [2-(4-hydroxyphenyl)ethanol] has not been explored for its cardioprotective effect and mechanism of action. Therefore, the present study was designed to evaluate the effect of tyrosol treatment (5 mg/kg/day for 30 days) on myocardial ischemic stress in a rat in vivo model of Myocardial Infarction (MI) and to identify key molecular targets involved in this mechanism. MI was induced by Left Anterior Descending (LAD) coronary artery ligation. Reduced infarct size (32.42 vs 48.03%) and cardiomyocyte apoptosis (171 vs 256 counts/100 HPF) were observed along with improvement in the myocardial functional parameters such as LVIDs (5.89 vs 6.58 mm), ejection fraction (51.91 vs 45.09%), and fractional shortening (28.46 vs 23.52%) as assessed by echocardiography in the tyrosol-treated animals when compared to the nontreated controls. We have also observed significant increase in the phosphorylation of Akt (1.4-fold), eNOS (3-fold) and FOXO3a (2.6-fold). In addition, tyrosol induced the expression of longevity protein SIRT1 (3.2-fold) in the MI group as compared to the non-treated MI control. Therefore tyrosol's SIRT1, Akt and eNOS activating power adds another dimension to the white wine research, because it adds a great link to the French paradox. In conclusion these findings suggest that tyrosol induces myocardial protection against ischemia related stress by inducing survival and longevity proteins that may be considered as anti-aging therapy for the heart. However, human intervention studies would be necessary before establishing any recommendations about dietary habits for tyrosol intake or administration of dietary supplements containing tyrosol.  相似文献   

Effect of Cereal Rye and Hairy Vetch on Pest Suppression and Corn Yield     

Mahesh Bashyal  J. Connor Ferguson  Oscar Perez-Hernandez  Nigel Hoilett 《Communications in Soil Science and Plant Analysis》2019,50(9):1093-1105

A study was conducted in 2016 to determine the effect of cereal rye (Secale cereale) and hairy vetch (Vicia villosa) combination on pest suppression and corn yield in Northwest Missouri. The experiments consisted of six treatments corresponding to cereal rye and hairy vetch combinations, plus a control. The corn treatments included conventional corn and transgenic corn. Harvested ears were assessed for rating on corn earworm damage and fungal damage on ears. Similarly, corn yield was measured across the treatments on randomly selected ears. Visual assessments of weed suppression, pest suppression (corn earworm damage), and fungal ear rots revealed no significant treatment effects. However, relevant trends in higher corn yield were observed with increasing hairy vetch proportion from 33% to 66% level. Delayed termination of hairy vetch caused poor corn growth and higher true armyworm (Mythimna unipuncta) infestation.  相似文献   

Soil hydrophysical properties under different nutrient management practices,their relationship with soil organic carbon fractions and crop yield under pigeonpea-wheat sequence     

Nintu Mandal  Brahma S. Dwivedi  Siba P. Datta  Mahesh C. Meena  Rakesh K. Tomar 《Journal of plant nutrition》2019,42(4):384-400

Soil physical degradation is one of the serious production constraints in the Indo-Gangetic Plain region. The present investigation was undertaken to study the effect of different nutrient management practices involving the use of fertilizer NPK alone or in combination with Farm Yard Manure (FYM), sulphitation pressmud (SPM), or induced defoliation (ID, imposed in pigeonpea through foliar spray of 10% urea solution at physiological maturity) on soil hydrophysical properties of a Typic Haplustepts under pigeonpea-wheat sequence, in a field experiment that continued for 5 years at IARI, New Delhi. Fertilizer NPK at recommended rate to both the crops resulted in a significant increase in macroaggregates, mean weight diameter, geometric mean diameter, water-stable aggregates, and saturated hydraulic conductivity in surface soil. Conjoint use of fertilizers, organic manures, and ID also decreased soil bulk density (0–15?cm) significantly over control. Effectiveness of organics and ID in improving soil physical environment was in the order: FYM?>?ID?>?SPM.  相似文献   

Phosphorus skipping effect on productivity,profitability and sustainability of rice-wheat cropping systems in Indo-Gangetic plains of India     

Subhash Chandra Tripathi  Subhash Chander  Raj Pal Meena 《Archives of Agronomy and Soil Science》2019,65(8):1134-1146

A field experiment was conducted for eight years at ICAR-Indian Institute of Wheat and Barley Research, Karnal, Haryana, India to study the skipping effect of P application on productivity, profitability and sustainability of rice-wheat cropping system. Rice yield and biomass were 8.35% and 6.6% higher where cowpea was grown after wheat compared to rice-vegetable pea-wheat crop sequence, respectively. Phosphorus application to rice or wheat or both crops exhibited at par rice grain yield, biomass, harvest index. Phosphorus application to both crops or only in rice crop produced maximum and significantly higher wheat yield (4.62 t ha^?1) as compared to P application only to wheat (4.48 t ha^?1). Eight years growing of green gram, cowpea and vegetable pea increased the organic carbon content 42.89, 16.38 and 4.57 %, respectively compared to the initial level. Skipping of P to either crop, by considering 13.5 million ha rice-wheat area, will save approximately Rs 40,500 million (Rs = Indian rupee) or US $ 623 million ($ = Rs 65) per year. Air pollution may be checked, due to saving on diesel in transportation of P fertilizer, to the tune of 60,383 tonnes of CO₂ per year by reducing emission of one of important global warming gas.  相似文献   

Information Communication Technology for Extension: A Mobile Phone Based Voice Call System for Dissemination of Cotton Production Technologies     

Satnam Singh  Omender Sangwan  Bhagwan Singh Meena  Om Prakash Tuteja  Harinder Pal Singh  Rishi Kumar 《Journal Of Agricultural & Food Information》2019,20(1):50-58

Dissemination of newer crop production technologies among growers is the major bottleneck in the existing extension system. This study proposes an innovative method for dissemination of cotton cultivation technologies through mobile phones. The voice advisories on different aspects of cotton cultivation were sent to mobile phones of growers, as and when required in the field. Feedback from growers revealed it as a highly acceptable extension technique, which helped them to make crucial time-specific decisions for crop management. The system has the potential to reach and benefit each and every grower at a very low cost compared to conventional training and visit extension system.  相似文献   

Long‐term effects of vehicular passages on soil carbon sequestration and carbon dioxide emission in a no‐till corn‐soybean rotation on a Crosby silt loam in Central Ohio,USA     

Gulab Singh Yadav  Rattan Lal  Ram Swaroop Meena 《植物养料与土壤学杂志》2019,182(1):126-136

Research information from a systematic planned study on the effects of vehicular passages and axle load on soil carbon dioxide (CO₂) fluxes and soil carbon (C) sequestration under long‐term NT farming is scanty. Therefore, the present study was conducted on an on‐going 20‐year experiment to assess the impacts of variable vehicular passages of a low axle load on soil CO₂ emission and soil C sequestration from a no‐till (NT) managed corn (Zea mays L.)–soybean (Glycine max Linneo) rotation in comparison with that a soil under woodlots (soils under natural wooded plantation). The experimental treatment consisted of an empty wagon [0 Mg load for compaction (C‐0; control)] compared with 2 (C‐2) and 4 (C‐4) passages of 2.5 Mg water wagon axle load, applied to the entire plot every year during April/May for 20 consecutive years. Soil samples were obtained in November 2016 to determine the effects of various vehicular passages on C and nitrogen (N) contents and CO₂ emissions. Soil CO₂ fluxes were measured from November 16, 2016, to May 30, 2017, on the bi‐weekly (November to December and April to May) and monthly (January to March) basis by using high‐density polyvinyl chloride static gas chambers. The soil CO₂ fluxes ranged from –1.05 to 9.03 g CO₂ m^?2 d^?1. The lowest soil CO₂ fluxes were observed in December coinciding with the minimum soil temperature. In general, daily soil CO₂ fluxes were higher under C‐0 than those under other treatments. Vehicular traffic and axle load reduced the cumulative emission of CO₂ by 22.6 and 29.8% under C‐2 and C‐4, respectively, compared with that under C‐0 (6.09 Mg ha^?1). Soil and air temperatures had a significant positive correlation with the diurnal fluxes of soil CO₂ in all the treatments except that under C‐4. Electrical conductivity, soil C and N contents and pools did not differ significantly among the treatments. Further, 2 to 4 passages of vehicles with 2.5 Mg of axle load decreased the soil CO₂ emission on Crosby silt loam under NT as compared to that under the control. Therefore, continuous cultivation of row crops with moderate trafficking under NT and residue retention is recommended, and it also reduces the potential of soil CO₂ emission while improving the soil organic C pools of well‐drained soils of Central Ohio.  相似文献
