The serological prevalence of foot and mouth disease virus (FmDV) among the cattle population in the North region of Cameroon was determined using ELISA (Enzyme Linked Immunosorbent Assays) serological tests for structural as well as non-structural proteins. In these cattle, FmDV RNA was identified, amplified, sequenced and the sequences were used to construct a phylogenetic tree. A sedentary cattle population randomly selected from six veterinary centres in the North region was sampled twice, six months apart. High prevalence of FmDV antibody was recorded in the first (402/466 (85.84%)) and second (358/411 (86.90%)) sampling periods. There was no significant difference (P > 0.05) in prevalence of FmDV antibody between the two sampling periods. Goudali and Peulh breeds of cattle and animals of three to five years old were the most infected with FmDV and mostly in the months of may and August. A seroprevalence of 100% (n = 14) of FmDV against serotypes A and O was observed in sera from convalescent animals in the study area. FmDV antigen detection ELISA showed a prevalence of 18/37 (48.65%) for serotypes SAT1 (8.1%), SAT2 (35.1%), A (10.8%) and O (2.7%) among the clinically infected animals. There was no significant difference (P > 0.05) in prevalence of FmDV RNA between the sampling periods. A prevalence of FmDV RNA (17.5% (n = 120) and 16.7% (n = 240)) was observed among the sedentary animals that were sampled four to five months apart. FmDV RNA prevalence of 28/37 (75.6%) among clinically infected animals was also observed, thus confirming all the 12 outbreaks investigated. Sequence analysis of VP1 coding gene of the SAT2 serotype showed that it was homologous to the Libyan isolates (that caused epidemics in northern Africa in 2012) and also clustered with the serotypes isolated from both Nigeria and Sudan in 2007.

Introduction: Haemodialysis is an exchange of solutes and water between the patient’s blood and a dialysis solution with a composition close to that of normal extracellular fluid, through a semi-permeable membrane. It is used in the treatment of acute or chronic renal failure. The aim was to study the clinical and paraclinical aspects and the outcome of patients starting dialysis treatment for renal failure in an emergency setting. method: This was a prospective study from 1 January to 31 July 2020, with a sample of 62 patients receiving haemodialysis in an emergency setting in the nephrology department of the Point G University Hospital. Results: The study showed that the sex ratio was 1.38 in favour of men and that the mean age of patients was 36.82 years. The group of patients with a low socio-economic standard of living dominated, accounting for 71% of cases. Hypertension and anaemia were the predominant risk factors in 77.4% and 87.3% respectively. Hyperphosphaemia, hypocalcaemia and secondary hyperparathyroidism accounted for 94.7%, 98.2% and 97.7% respectively. Left ventricular hypertrophy was 29.27% on electrocardiogram and 22% on cardiac ultrasound. Isolated cardiomegaly was found in 30.76% of patients. The main indications for dialysis were uraemic syndrome (69.2%), pericardial friction (27.4), anuria for 48 hours (20.1%), hyperkalaemia (17.7%) and acute lung oedema (16.1%). The mean duration of haemodialysis was less than one month in one out of two cases. There was no significant association between age and time on dialysis (p = 0.178). The death rate was 20.97%. Case fatality was higher in patients whose duration of dialysis was less than one month than in the others (p = 0.0006). Conclusion: CKD is a public health problem in mali. It affects young people, especially males. Low economic income is an obstacle to the management of this disease.

For the first time, sodium metasilicate （SmS） doped ammonium dihydrogen phosphate （ADP） crystal was grown by slow evaporation solution technique. The unit cell parameters of grown crystal were deter- mined by means of single crystal X-ray diffraction technique. The qualitative analysis of SmS doped ADP crystal was carried out using energy dispersive X-ray and Fourier transform infrared analysis. The in- crease in optical transparency of doped ADP crystal was ascertained in the range of 200-900 nm using the UV-visible spectral analysis. The vital optical constants were evaluated using the transmittance data to explore various optical device applications of crystal. The assertive influence of SmS on mechanical and dielectric behavior of ADP crystal was investigated by means of Vickers microhardness analysis and dielectric studies, respectively. The enhancement in second harmonic generation （SHG） efficiency of SmS doped ADP crystal with reference to potassium dihydrogen phosphate （KDP） and ADP was confirmed from Kurtz-Perry SHG test. The Kerr lensing nonlinearity in SmS doped ADP crystal was identified by means of Z-scan analysis and the third order nonlinear optical susceptibility （χ3） was found to be 6.19 × 10-5 esu, which vitalizes its application for laser stabilization systems.

利用放射性束68Fe轰击液氢靶引起的敲出反应,研究了极端丰中子核^(63,65,67)mn的激发态,指认了它们的自旋宇称,建立了这三个原子核的能级纲图。纲图包含11/2^(-)、9/2^(-)和7/2^(-)三个激发态以及5/2^(-)_(g.s.)基态,它们由三条ΔI=1的γ跃迁连接。这种能级结构与K=5/2时强耦合转动带的特征一致。使用改进的LNPS有效相互作用(LNPSm)的大规模壳模型计算能很好地重现观测到的能级。计算表明,^(65,67)mn的低位激发态都主要包含处于4p-4h的中子组态和1p-1h的质子组态。基于实验结果发现,在吸积中子星壳中,与质量数A=63相关的Urea中微子冷却效果比预期的要强很多,而A=65,67的冷却效果比预期的更弱。

Introduction: Acute coronary syndrome is often the first event of coronary disease of young subjects. Objective: To study sociodemographic, clinical, paraclinical, therapeutic and evolutionary aspects of acute coronary syndrome of young subjects. Patients and methods: Descriptive cross-sectional study with prospective recruitment from October 01, 2020 to march 31, 2022. Were included all patients admitted for acute coronary syndrome whose age was less or equal to 45 years and who had undergone coronary angiography at the mother-Child University Hospital on Luxembourg from Bamako. Results: During the study period, we collected 60 patient files out of 198. These 60 patient files met our inclusion criteria. Hospital frequency was 30.30%. Average age of patients was 40.43 ± 3.9 years. Sex ratio m/F was 5.3. main cardiovascular risk factor was smoking tobacco (23.42%), followed by dyslipidemia (13.92%). Functional signs were dominated by angina 62% followed by dyspnea 25.3%. Persistent ST-segment elevation on electrocardiogram was present in 76.4%. Left ventricular systolic dysfunction was present in 26.5%. Time to first medical contact was more than 12 hours in 62.7% of cases. Radial approach was adopted in 94% of cases. Coronary angiography was pathological in 85% (n = 51) of cases. Lesions were single-vessel disease in 47.1% and culprit artery was anterior interventricular in 51% of cases. Dual anti-platelet aggregation was aspirin and ticagrelor in 91.8% of cases. Angioplasty was performed in all patients who had significant abnormalities at coronary angiography. In-hospital mortality was 3.9%. Conclusion: Acute coronary syndromes exist in young Africans with a male predominance. main cardiovascular risk factor is smoking tobacco. Coronary lesions are single vessel disease in the majority of case. most of patients meet medical team after 12 hours. Time to first medical contact is a main challenge in our country.

Optimization of a High Throughput, Cost Effective, and All-stage DNA Extraction Protocol for Sorghum （Sorghum bicolor）

引用

Journal of Agricultural Science and Technology 2011年第2期5卷 243-250页

作者： A. Adugna P. m. Sweeney A. A. Snow Department of Biology Addis Ababa University P.O. Box 3434 Addis A baba Ethiopia Department of Evolution Ecology and Organismal Biology Ohio State University Columbus Ohio 43210 USA

The extraction of DNA for molecular analyses is often a limiting factor in terms of cost, time, and availability of skilled labor Here the authors describe a simple extraction protocol for obtaining DNA from field and greenhouse grown plants. This method was optimized for sampling mature wild sorghum populations in remote areas of Ethiopia and young greenhouse grown seedlings for genetic studies using microsatellite loci. Initially, the leaf squashes are made on Whatman FTA plant saver cards or small cards of Whatman chromatography paper. After several washes, sufficient DNA to run up to 70 PCR amplifications is eluted from a 6 mm disk. Both types of cards were equally effective for collecting genomic DNA from young and mature sorghum plants for PCR-based analyses. The use of this technology for extracting genomic DNA from seedlings and/or mature plants in situ is particularly attractive for sampling at sites that are far from the laboratory where samples are ultimately analyzed. moreover, highly skilled personnel are not required to collect DNA samples using this protocol. The Whatman FTA card is more expensive than the Wbatman chromatography paper. Therefore, without compromising efficiency, the lower cost chromatography paper can be used for DNA extraction, especially for institutions in developing countries.
