Objective: The aim of this study was to determine maternal and perinatal complications of pregnancies complicated by severe preeclampsia in three tertiary care centers in Cameroon. Methods: We carried out a descriptive cross sectional study from the 1st of June 2012 to the 31th of June 2014, among pregnant women with severe preeclampsia followed up in three tertiary level hospitals in Yaoundé, Cameroon: the Yaoundé General Hospital, the Yaoundé Central Hospital, and the Yaoundé University Hospital. Statistical analysis was performed using EPI 3.5.5. Data were described as means ± standard deviation, percentages and numbers. Chi-square and Fisher exact tests were used where appropriate. Results: Of the 2500 deliveries registered during the study period, 111 cases (8.49%) were managed as severe preeclampsia. Four patients refused to participate and were excluded from the study. Most of these patients were non workers (58.0%), pauciparous (61.7%) and young (median age of 27.47 years ± 6.46). Eclampsia (12.14%), abruptio placentae (11.21%) and hypertensive retinopathy (7.47%) were the most frequent maternal complications. Two cases (1.86%) of maternal deaths occurred in patients who had eclampsia. Prematurity (48.6%), intra uterine fetal death (13.1%) and oligoamnios (11.2%) were the most frequent fetal complications. All four neonatal deaths occurred in women in whom the diagnosis of severe preeclampsia was done between 28 and 33 weeks of gestation. Conclusion: Pregnancies complicated by severe preeclampsia had significantly high maternal and perinatal morbidity and mortality in Cameroon. The complications of severe preeclampsia can be prevented by more widespread use of antenatal care, education of primary medical care personnel, prompt diagnosis of high-risk patients and timely referral to tertiary medical centers.

Introduction: Most cases of extrauterine pregnancies present in the ruptured state in low-resource settings and patients with haemodynamic instability risk mortality without swift intervention. An idea of when ectopic gestations are likely to present may be useful for logistic planning and facility readiness for case management. The study sought to assess the incidence of extrauterine gestation, mode of management and any link with seasonal and/or sociocultural events within the Cape Coast metropolis of Ghana over a 9-year review period.?Methods: A retrospective review of all cases of extrauterine pregnancies managed at the Cape Coast Teaching Hospital (CCTH) from January 2010 to December 2018 was conducted. Data on patient age, parity, month of presentation, site and laterality of ectopic gestation, number of abortions and deliveries were retrieved from hospital records and analysed. Yearly and monthly aggregated incidence of extrauterine pregnancies were computed.?Result: A total of 480 ectopic pregnancies out of 26,850 total pregnancies were seen over the period, giving an overall occurence of 17.9/1000 pregnancies and almost all were managed surgically. Half of all the cases occurred in the 20?-?29 years age group while the extremes of age recorded the lowest. An average of about 53 cases per year was recorded for the period under review. The peak months of occurrence were October and November. About 83% were ruptured with the ampulla region being the commonest site. Conclusion: The data suggests increased ectopic gestation occurrence in the Cape Coast metropolis about two months after the major traditional festivals and this may have implications for instituting mitigating measures, logistic management and facility preparedness for case management.

We propose and investigate,both experimentally and theoretically,a novel mechanism for switching and modulating plasmonic signals based on a Fano interference process,which arises from the coupling between a narrow-band optical Fabry–Pérot cavity and a surface plasmon polariton(SPP)*** SPP wave emitted from the cavity is actively modulated in the vicinity of the cavity resonances by altering the cavity Q-factor and/or resonant *** experimentally demonstrate dynamic SPP modulation both by mechanical control of the cavity length and all-optically by harnessing the ultrafast nonlinearity of the Au mirrors that form the *** electro-optical modulation scheme is also proposed and numerically *** operation of the switch via mechanical means yields a modulation in the SPP coupling efficiency of~80%,while the all-optical control provides an ultrafast modulation with an efficiency of 30%at a rate of~0.6 *** experimental observations are supported by both analytical and numerical calculations of the mechanical,all-optical and electro-optical modulation methods.

Culture of Scenedesmus acuminatus in Corn Steep Liquor

Journal of Agricultural Science and Technology(B) 2017年第5期7卷 346-350页

Microalgae have been evaluated as a source of lipids for biodiesel production. They can be grown on effluent and produce biomass while removing organic and mineral components from the medium. The use of agro-industrial wastes for the production of microalgae is an alternative to reduce the costs related to the composition of the culture medium, thus reducing operational costs considerably. This work was conceived as a research about the cultivation of microalgae Scenedesmus acuminatus on the substrate composed by corn steep liquor. A central composite design （CCD） was carried to study the influence of the effluent and inoculum concentration on the chemical oxygen demand （COD） of the culture. Statistical analysis indicated that the percentage of inoculum and effluent had an influence on the COD. The cultivation, together with the coagulation procedure, was efficient for the removal of organic matter, verified through the COD reduction and changing of pH value. These two parameters reached the appropriate level according to the standard required by current legislation.

Introducing New Peptide Extracts from Saccharomyces cerevisiae and Achatina achatina Fluids with Strong Inhibitory Activities on Human α-Amylase

引用

Journal of Biosciences and Medicines 2022年第11期10卷 226-239页

This study aimed at exploring for new natural peptides with strong inhibitory capabilities on α-amylase, the main metabolic enzyme that regulates mellitus diabetes, in order to contribute in controlling this global pandemic. It has consisted in heat shock (to 60°C, 70°C, 80°C, 90°C and 100°C for 10, 20 and 30 minutes) of crude proteins extracted from biomass and extracellular parts of Saccharomyces cerevisiae under cultivation, and from the digestive fluid of the giant snail Achatina achatina, and in-vitro assays of the resulting solutions, as effectors, in human α-amylase catalyzing reactions. The results showed that whatever the temperature and time of treatment, an increase (from 2.65 to 3.98-fold) in proteins concentration was noticed. When blended up to 75 microliters in reaction mixtures, the three peptide extracts showed beyond 11% of inhibition of initial α-amylase activity. By reducing samples volume, only 5 microliters of the studied peptide extracts representing 4.70 μg of S. cerevisiae biomass peptides, 0.55 μg of S. cerevisiae extracellular peptides or 1.05 μg of peptides from the digestive fluid A. achatina were quite sufficient to induce complete (100%) inhibition of the human α-amylase activity. Compared to the inhibitory effect obtained from 2.50 μg of acarbose, a renowned antidiabetic, the studied peptide effectors showed more pronounced inhibitory activities. So, we can positively state that S. cerevisiae as well as A. achatina are both capable of synthesizing proteins made up of small inhibitory peptides which deserve purification and structural analysis for potential exploitation as healthy antidiabetic drugs.

1.介绍钠钙玻璃熔炉通常装备电熔耐火材料。这些耐火材料一般属于AZS类型,其主要氧化物组成:氧化铝、氧化锆和二氧化硅。为了确保高质量玻璃,例如避免玻璃缺陷,这些耐火材料一直是个战略上的选择。窑炉蓄热室的耐火材料,即使它们并不与玻璃液接触,也必须谨慎地选择以便提供更长的寿命和最佳的热效率。尤其是在能源成本长期不断上涨的趋势下(图1),热效率正日复一日地成为重要课题。
