[Methods] Ninety two four-month-old Tan sheep were randomly divided into two treatment groups according to their body weight, 46 in each group. The control check group(CK) was feed with conventional diet, and the experimental group was fed with the addition of antimicrobial peptide on the basis of the conventional diet, with the added amount of 2.5 g/sheep per day. The experimental period was 60 d. [Results] The incidence rate was 75.06% lower in the experimental group than in the CK. The average daily weight gain per sheep was 11.27% higher in the experimental group than in the CK(P<0.05). The feed conversion ratio was 8.45% lower in the experimental group than in the CK(P<0.05). The average daily gross profit per sheep was 12.12% higher in the experimental group than in the CK. For slaughter performance, the data difference of each item was not significant. The PH at 45 min and 24 h after slaughter was within the normal range of fresh mutton. The cooked meat percentage and water loss rate showed no significant differences(P>0.05). The marbling ranged from 2.45 to 2.50, indicating that the fat content was moderate, and the difference between groups was not significant(P>0.05). The flesh color ranged from 3.00 to 3.15, between light red and bright red, belonging to the normal color of mutton, and the difference between groups was not significant(P>0.05). The shear force was between 2.50 and 2.65, without a significant difference between groups(P>0.05). The white blood cells, lymphocytes and platelets in the experimental group were lower than those in the CK(P<0.01). The erythrocytes and hemoglobin in the erythrocyte group were higher than those in the CK(P<0.05). The neutrophils and monocytes in the experimental group were lower than those in the CK(P<0.05). [Conclusions] This study provides a technical basis for the rational use of antimicrobial peptides and their application in ruminants.展开更多

Due to different pull-push electronic effects of ligands, the fluorescence intensities of these terbium complexes significantly varied, that is: LⅡ·Tb 〉L(Ⅲ)·Tb〉 LⅠ·Tb. Meanwhile, the characteristic peaks at 492 nm(5D4→7F6) and 547 nm(5 D4→7F5) showed "Off–On–Off" fluorescence response to various p H conditions,which indicated that all of them can be used as the highly sensitive pH fluorescent probes. Notably, using LⅡ·Tb with the best fluorescence performance as a probe, some patients' urine samples can be easily monitored through the response triggered by pH value. Therefore, LⅡ·Tb has the potential to auxiliarily diagnose some diseases in clinical practice through p H detection of routine urine test.展开更多

More advanced laboratory analyses to detect or monitor hypercoagulation have not yet been introduced into routine clinical management. Thromboelastography assesses the influence of plasma factors and platelets during all phases of haemostasis, thus permits evaluation of hypo- and hyper- coagulation status. This prospective study included assessment of 35 patients with thrombotic complications (II-nd group), compared with 34 healthy controls (I-st group). Haemostasis was analyzed with routine clotting tests: protrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, platelets and rotation thromboelastography (ROTEM~) with measuring time to 20 min. All data are presented as mean and standard deviation (SD). Statistical comparisons of samples were performed by student's t-test. The sensitivity, specificity, positive and negative predictive value of the parameters was calculated by using the receiver operator characteristic (ROC) curves for two groups. There was significant difference (P 〈 0.05) observed in the parameters of ROTEM: clot formation time (CFT), a-angle, maximum clot firmness (MCF) and thrombodynamic potential index (TPI) in the patient's population compared to the healthy controls. No significant difference was observed in CT (ROTEM) and routine coagulation tests when the two groups were compared. Rotation thromboelastography analysis demonstrated to be a reliable method for diagnosis of hypercoagulable state.展开更多

The transformation of dura palm kernel shells into micronized shell powder as well as its characterization was the subject of recent work. We carried out, the formulations by using the industrial scales of precision, the mixtures of the instrants with an industrial machine of mark HENSHLLE N˚2 MAIN 570762, the routine tests by ATG/DSC then by IRTF, the extrusion of the tubes with an extruder twin-screw with 9 rooms of transformation finally the tests of conformity by the observations and the analyses. We obtained for the formulations the dosage of 0%, 4.01%, 12.54%, 23.03%, 32.01%, 38.01%, 51.02% representing the percentage of hull powder in the mixture, the machine mixing gave perfectly homogeneous powders, the routine tests showed that the hull powder keeps all its properties until the end of the shaping whatever the percentage of hulls contained in the PVC, the extrusion gave tubes for each formulation and the conformity tests gave perfectly round tubes of diameter 90 × 82 mm, a coloration going from white grey at 0% to dark black at 51.02% showing the influence of the carbon black and the color of the shell powder according to its proportion. The infrared of the tubes obtained shows for each formulation a variation of the CH<sub>2</sub> and CH bonds and a decrease of the −OH bonds. The thermogravimetric analyses and the differential calorimetric analyses of the tubes of each formulation, show each time that the quantity of shell powders in the mixture influences the PVC tubes obtained. Thus, we obtain a variation of the phase temperatures according to the dosage, giving from 108.72<span style="white-space:normal;">˚</span>C to 76.56<span style="white-space:normal;">˚</span>C for the glass transition temperature and from 494.71<span style="white-space:normal;">˚</span>C to 414.56<span style="white-space:normal;">˚</span>C for the melting temperature, at the DSC and a progressive decrease of the mass following the heat absorption with each time 4 phases instead of 5 for the unloaded PVC tubes at the ATG according to the dosage.展开更多
