Abstract
AIM Assess prevalence of metabolic syndrome (MetS) in black Africans hypertensive patients. POPULATION Prospective survey from 3rd November 2014 to 12th June 2015, at Abidjan Heart Institute. Study was carried out among patients aged 18 years old, admitted to external consultation. Oral consent was obtained. MetS was established based on the definitions of the NCEP-ATP III 2005 and the International Diabetes Federation (IDF). RESULTS Over 1246 hypertensive patients, 404 were included in our study. The prevalence of MetS was 48.8% according to the criteria of the NCEP-ATP III 2005 and 51% according to the IDF. We noticed a female predominance (69% against 31%, P<0.001). Central obesity (49.5%) and low HDL-cholesterol (42.1%) were the factors defining the SM most predominant in our series. Low blood pressure control was higher in the presence of MetS (43.6%). The average number of antihypertensive prescribed drugs were significantly higher (2.2±0.8 against 2±0.8, P<0.001). MetS was significantly associated with obesity (BMI≥30kg/m(2) : 40.6% against 14%, P<0.001). Cardiovascular complications were observed in 54.8% of hypertensive patients in the presence of MetS. CONCLUSION MetS is a reality in sub-Saharan Africa. Adequate preventive measures are needed to limit its progression.

Abstract
In this study, we aims to investigate the effects of edible bird's nest (EBN) on anti-aging efficacy. In order to investigate lifespan and mortality rate of flies, we treated flies with various doses of EBN. Besides, fecundity, water content and food are determined and heat-stress test is conducted after flies treating with different medium. Effects of EBN on total antioxidant activity (T-AOC), super-oxide dismutase activity (SOD), catalase activity (CAT), and malondialdehyde (MDA) were examined in drosophila melanogaster. Results indicated that flies in EBN treated group illustrated significantly lower mortality rates and longer median and maximum lifespan compared to control group (P<0.05). The fecundity in EBN-treated group was increased compared to control group. SOD levels and CAT activity were significantly increased, and MDA levels decreased in EBN-treated group compared to control group (P<0.01). In conclusion, EBN can extend lifespan, decrease mortality rate and increase survival rate in heat-stress test, and which can also promote SOD and CAT activity and reduce MDA levels. EBN is able to delay drosophila melanogaster aging, attributing to the increasing antioxidant enzyme activities and decreasing content of lipid peroxidation products in drosophila melanogaster.

Abstract
AIM To assess prevalence, characteristics and management of acute coronary syndromes in sub-Saharan Africa population. PATIENTS AND METHODS Prospective survey from January, 2010 to December, 2013, carried out among patients aged 18 years old, admitted to intensive care unit of Abidjan Heart Institute for acute coronary syndrome (ACS). RESULTS Four hundred and twenty-five (425) patients were enrolled in this study. Prevalence of ACS was 13.5%. Mean age was 55.4±11 years. Clinical presentation was predominantly ST-segment elevation myocardial infarction (STEMI) in 71.5% of subjects, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) accounted for 28.5%. Two hundred and eighty patients (65.9%) were transferred by unsafe transportation. Among the 89 patients admitted within 12hours of the onset of symptoms, primary percutaneous coronary intervention was performed in 20 patients (22.5%), or 6.6% of STEMI as a whole. Twenty-five patients (8.2%) received fibrinolytic therapy with alteplase. In-hospital death rate was 10%. CONCLUSION The prevalence of acute coronary syndromes is increasing in sub-Saharan Africa. Excessive delays of admission and limited technical facilities are the major difficulties of their management in our regions.

Abstract
INTRODUCTION Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant tumor of the pancreas with poor prognosis. The lack of understanding of the molecular mechanisms of PDAC and biomarkers for early diagnosis might be two of the reasons for the poor prognosis of PDAC. MATERIALS AND METHODS ILK and ERP29 protein expressions in PDAC, peritumoral tissues, benign pancreatic lesions, and normal pancreatic tissues were measured by immunohistochemistry and the clinical and pathological significances of ILK and ERP29 in PDAC were analyzed. RESULTS The percentages of positive ILK and negative ERP29 expressions were significantly higher in PDAC tumors than in peritumoral tissues, benign pancreatic tissues, and normal pancreatic tissues (P < 0.01). Benign pancreatic lesions with positive ILK and negative ERP29 expressions exhibited dysplasia or intraepithelial neoplasia. The percentage of cases with positive ILK and negative ERP29 expressions was significantly lower in PDAC patients without lymph node metastasis and invasion, and having TNM stage I/II disease than in patients with lymph node metastasis, invasion, and TNM stage III/IV disease (P < 0.05 or P < 0.01). Kaplan-Meier survival analysis showed that positive ILK and negative ERP29 expressions were significantly associated with survival in PDAC patients (P < 0.001). Cox multivariate analysis revealed that positive ILK and negative ERP29 expressions were independent poor prognosis factors in PDAC patients. CONCLUSIONS Positive ILK and negative ERP29 expressions are associated with the progression of PDAC and poor prognosis in patients with PDAC.

Abstract
We used RT-PCR, nested PCR to acquire the partial 5'- race fragment of rabbit HGF cDNA and the partial 3'- race fragment of rabbit HGF cDNA. Then, we used recombination PCR to acquire rabbit HGF successfully. Homology analysis was conducted among the sequence of RABHGF and known human and rat HGF by DNAStar. It was proved that high level of homology existed among the sequences of those three HGF genes. We used the acquired gene of RABHGF to construct its recombinant eukaryotic expression vector pcDNA3.1(+)-RABHGF (pRABHGF). The identification of the eukaryotic expression vector pRABHGF by PCR, restriction enzyme and sequencing analysis showed that rabbit HGF gene was correctly inserted into the vector. pRABHGF and pcDNA3.1(+) as controls were transfected into COS-7 cells by lipofectamine. It takes 24h-36h after transfection to detect the expression of RABHGF protein by indirect immunofluorescence assay (IFA). The proliferation of cos-7 cells were evaluated by MTT assay. The result displayed positive effect of RABHGF protein on the proliferation of COS-7 cells. This study lays the foundation for a new gene therapy method for ischemic heart disease.

Abstract
Brassicaceae is a large plant family of special interest; it includes many economically important crops, herbs, and ornamentals, as well as model organisms. The taxonomy of the Brassicaceae has long been controversial because of the poorly delimited generic boundaries and artificially circumscribed tribes. Despite great effort to delimitate species and reconstruct the phylogeny of Brassicaceae, little research has been carried out to investigate the applicability and effectiveness of different DNA regions as barcodes - a recent aid for taxonomic identification - to identify economically important species in Brassicaceae. In this study, we evaluated the feasibility of five intensively recommended regions [rbcL, matK, trnH-psbA, internal transcribed spacer (ITS), ITS2] as candidate DNA barcodes to discriminate economic species of Brassicaceae in China and try to establish a new digital identification method for economic plants of Brassicaceae. All sequences of 58 samples from 27 economic species (Brassicaceae) in China were assessed in the success rates of PCR amplifications, intra- and inter-specific divergence, DNA barcoding gaps, and efficiency of identification. Compared with other markers, ITS showed superiority in species discrimination with an accurate identification of 67.2% at the species level. Consequently, as one of the most popular phylogenetic markers, our study indicated that ITS was a powerful but not perfect barcode for Brassicaceae identification. We further discuss the discrimination power of different loci due to inheritance pattern, polyploidization and hybridization in species-specific evolution. Further screening of other nuclear genes related to species isolation as plant barcode candidates is also proposed.

Abstract
Vibrio parahaemolyticus is a leading cause of food-borne diarrhoea in coastal countries. Although V. parahaemolyticus cases have been reported since 1950, they have been poorly documented. From July 2009 to June 2013, we collected 6951 faecal specimens for pathogen detection; V. parahaemolyticus strains were isolated from 563 specimens (8.1%). We then analysed the characteristics of the 501 V. parahaemolyticus strains that were isolated as the sole pathogen. Twenty-one serotypes were identified among these strains; O3:K6 was the most common serotype (65.1%), followed by O4:K8, O4:K68 and O1:K36. One strain of the O4:K18 serotype was isolated from clinical patients for the first time. Pandemic O3:K6 clones were predominant and accounted for 69.1% of all of the pandemic strains. This is the first report of one strain expressing the O3:K8 serotype with a pandemic genotype. The presence of the haemolysin gene tdh (93.0%) was the key characteristic of the virulent strains; however, a few strains carried the trh gene. We also confirmed the presence of the type III secretion system 2 (T3SS2) genes in all of the pathogenic strains. Subsequent multilocus sequence typing split the isolates into 16 sequence types (STs), with ST3 and ST88 as the most prevalent in southeastern China. Most isolates were sensitive to common antimicrobial agents, apart from ampicillin. However, the resistance rate to ampicillin has apparently increased in this area. In conclusion, our results indicate that pandemic O3:K6 V. parahaemolyticus isolates are predominant in southeastern China, and additional surveillance should be conducted to facilitate control of the transmission of this pathogen.

Abstract
We investigated the biological significance of microRNA-126 (miR-126) expression in patients with atrial fibrillation (AF) and/or heart failure (HF) to examine the possible mechanism of miR-126-dependent AF and development of HF. A total of 103 patients were divided into three groups: AF group (18 men and 17 women, mean age: 65.62±12.72 years), HF group (17 men and 15 women, mean age: 63.95±19.71 years), and HF-AF group (20 men and 16 women, mean age: 66.56±14.37 years). Quantitative real-time PCR was used to measure relative miR-126 expression as calculated by the 2-ΔΔCt method. miR-126 was frequently downregulated in the 3 patient groups compared with controls. This reduction was significantly lower in permanent and persistent AF patients than in those with paroxysmal AF (P<0.05, t-test). Moreover, miR-126 expression was markedly lower in the HF-AF group compared with the AF and HF groups. The 3 patient groups had higher N-terminal prohormone brain natriuretic peptide (NT-proBNP) levels, lower left ventricular ejection fraction (LVEF), larger left atrial diameter, and higher cardiothoracic ratio compared with controls. There were significant differences in NT-proBNP levels and LVEF among the AF, HF, and HF-AF groups. Pearson correlation analysis showed that relative miR-126 expression was positively associated with LVEF, logarithm of NT-proBNP, left atrial diameter, cardiothoracic ratio, and age in HF-AF patients. Multiple linear regression analysis showed that miR-126 expression was positively correlated with LVEF, but negatively correlated with the logarithm of NT-pro BNP and the cardiothoracic ratio (all P<0.05). Serum miR-126 levels could serve as a potential candidate biomarker for evaluating the severity of AF and HF. However, to confirm these results, future studies with a larger and diverse patient population are necessary.

Abstract
OBJECTIVE Epileptic seizure can increase the cell proliferation in dentate gyrus in brain, but the mechanism remains unclear. MATERIALS AND METHODS In this study, using systemic bromodeoxyuridine (BrdU) to label the dividing cells, the inhibitory effect of group II metabotropic glutamate receptor (mGluR) agonist 2R, 4R-4-aminopyrrolidine-2, 4-dicarboxylate (2R, 4R-APDC) on cell proliferation in dentate gyrus in rats after pilocarpine-induced status epilepticus (SE) was investigated. RESULTS Results found that, 2R, 4R-APDC could significantly inhibit the behavioral seizure and block the seizure-induced increase of BrdU-positive cells in dentate gyrus, especially in hilus. Double-label immunofluorescence staining showed that, 2R, 4R-APDC did not affect the ability of newborn cells to differentiate into neurons or astrocytes. CONCLUSIONS 2R, 4R-APDC not only has anticonvulsant effect on adult rats with pilocarpine-induced SE, but also has neuroprotective effect by reducing the abnormal regeneration of nerves.

Abstract
We have developed a Si opt-neural probe with multiple waveguides and metal cover for highly accurate optical stimulation. This neural probe had 16 recording sites, three optical waveguides, and metal cover for suppressing light leakage. We evaluated electrochemical properties of the recording sites, and confirmed that the neural probe had suitable characteristics for neural recording. We also demonstrated the optical stimulation to the neurons expressing ChR2 using our probe. As a result, we succeeded multisite optical stimulation, and observed that no light leakage from the optical waveguides because of the metal cover. From in vivo experiments, we successfully recorded optically modulated local field potential using the fabricated Si neural probe with optical waveguides. Moreover, we applied current source density analysis to the recorded LFPs. As a result, we confirmed that light induced membrane current sink in locally stimulated area. Our Si opto-neural probe with multiple optical waveguides and metal-cover is one of the most versatile tools for optogenetics.

Abstract
INTRODUCTION Self-medication practice is under-evaluated among black African hypertensive patients. AIM To assess the level of self-medication among black African hypertensive patients and to determine the factors favoring this practice and their consequences. METHODS Prospective study during a 3-month period including 612 hypertensive patients followed in Abidjan cardiology institute. RESULTS Mean age was 55.1. The patients had a self-medication use in 60.1% of cases. Medicinal plants and derived products were commonly involved. Self-medication use reasons were: influence of relatives (89.8%) and the fear of antihypertensive drugs adverses effects (54.9%). Multivariate analysis shows that factors of self-medication were age (56.6 years vs. 50.3 years, P<0.001), income less than 762 euros/month (88% vs. 75.4%; OR=2.73; 95% CI: 1.62-4.6; P<0,0001), obesity (70.4% vs. 35.6%; OR=1.24; 95% CI: 0.75-1.15; P=0.037), dyslipidemia (40.8% vs. 27.9%; OR=6.72; 95% CI: 0.57-2.13; P=0.043), antihypertensive association therapy (61.7% vs. 51.4%; OR=2.27; 95% CI: 0.25-0.97; P=0.037). Poor control of high blood pressure (HBP) was a consequence of self-medication (6.5% vs. 47.1%; OR=10.27; 95% CI: 4.65-56.4; P=0.034), repercussions of HBP on major organ (75% vs. 17.2%; OR=12.9; 95% CI: 8.5-19.6; P=0.0001). CONCLUSION Self-medication is a common practice in African hypertensive patients. It has many consequences.

Abstract
The aim of the study was to evaluate the clinical value of serum high mobility group box chromosomal protein 1 (HMGB1) in ovarian cancer and analyze the correlation between HMGB1 and ovarian cancer clinicopathologic outcomes.A total of 105 patients with diagnosed epithelial ovarian cancer, 46 patients with ovarian benign disease and 33 healthy volunteers were enrolled from January 2011 through January 2013. Serum HMGB1 levels were analyzed by enzyme-linked immunosorbent assay.The mean value of serum HMGB1 levels in ovarian cancer patients (78.18±54.87ng/ml) was significantly higher than those in benign patients (33.98±9.97ng/ml) and healthy control (26.71±7.99ng/ml, p < 0.0001), respectively. The serum HMGB1 levels were 40.33±6.50ng/ml, 61.16±20.15ng/ml, 81.81±51.15ng/ml and 119.48±84.28ng/ml in patients with TNM stage I, II, III, and IV, respectively (p < 0.0001). There were 81 of the 105 ovarian cancer patients obtained complete remission, the serum HMGB1 levels before treatment(71.99±42.49ng/ml) were much higher than that at remission stage(42.10±15.48ng/ml) (p < 0.0001). During our investigating period, 28 ovarian cancer patients underwent recurrence, the serum HMGB1 levels were 75.54±39.50ng/ml in these recurrent ovarian cancer patients compared to 42.04±10.68ng/ml in non-recurrent ovarian cancer (p < 0.0001). None of the remission or recurrent patients came from benign ovarian tumor group.Our study suggests that HMGB1 may be a useful clinical marker for evaluating progression and predicting prognosis of ovarian carcinoma. Targeting HMGB1 production or release might have potential approaches for ovarian carcinoma treatment.

The experiment was designed to determine precisely the energy dependence of s- and p-wave electromagnetic multipoles as a stringent test of the predictions of chiral perturbation theory (ChPT). The data were taken with an electron beam energy of 1192 MeV using a two-spectrometer setup in Hall A at Jefferson Lab. For the first time, complete coverage of the ϕ_{π}^{*} and θ_{π}^{*} angles in the pπ^{0} center of mass was obtained for invariant energies above threshold from 0.5 up to 15 MeV. The 4-momentum transfer Q^{2} coverage ranges from 0.05 to 0.155 (GeV/c)^{2} in fine steps. A simple phenomenological analysis of our data shows strong disagreement with p-wave predictions from ChPT for Q^{2}>0.07 (GeV/c)^{2}, while the s-wave predictions are in reasonable agreement.

Abstract
INTRODUCTION Sleep apnea syndrome (SAS) is very little described in the hypertensive black African. PURPOSE To screen sleep apnea syndrome using the rating scale of Epworth daytime sleepiness, and to investigate the determinant factors and to infer therapeutic consequences. METHOD This is a retrospective and prospective study with descriptive and analytical purpose that focused on 200 hypertensive outpatients of the Cardiology Institute of Abidjan. The primary endpoint studied was the SAS. The diagnostic approach of SAS was performed using the rating scale of Epworth daytime sleepiness. RESULTS The prevalence of sleep apnea was 45%. The average age of sleep apnea carriers was 56.1 years, with a male predominance (60%). The determinant factors of sleep apnea syndrome were male gender (60% versus 40%, P=0.021), obesity (77.8% versus 62.7%, P<0.0001), diabetes (26.7% versus 15.5%, P=0.5) and dyslipidemia (54.4% versus 27.3%, P=0.0009). Life in urban areas, occupation and smoking were not correlated with SAS in our series. The control of hypertension was better in non-apneic patients compared to apneic patients (63.6% versus 38.9%, P=0.04). The visceral impact of hypertension in apneic patients was highly significant (77.8% versus 41.7%, P=0.014). Therapeutically, it was noted the preferential prescription of combination therapy in apneic patients compared to non-apneic patients (82.3% versus 74.4%).

Abstract
Since the discovery of aflatoxins in the 1960s, much research has focused on detecting the toxins in contaminated food and feedstuffs in the interest of public safety. Most traditional detection methods involved lengthy culturing and/or separation techniques or analytical instrumentation and complex, multistep procedures that required destruction of samples for accurate toxin determination. With more regulations for acceptable levels of aflatoxins in place, modern analytical methods have become quite sophisticated, capable of achieving results with very high precision and accuracy, suitable for regulatory laboratories and for post-harvest sample testing in developed countries. Unfortunately, many countries around the world that are affected by the aflatoxin problem do not have ready access to high performance liquid chromatography and mass spectrometry instrumentation and require alternate, readily available and simple detection methods that may be used by small holdings farmers in developing countries. This paper presents an overview of the existing detection and/or determination methods for aflatoxins. The traditional, quantitative, chemically-based analytical strategies for detecting aflatoxins in maize and their evolution to the modern instrumentation routinely used in developed countries are reviewed. Additionally, novel, more streamlined, user-friendly and in some instances, non-destructive, methods that may be useful for semi-quantitative or qualitative, quick-screening of contaminated maize samples appropriate also for use in developing countries, are discussed.

Abstract
INTRODUCTION Diabetic peripheral arterial disease (PAD) of the lower limbs is underdiagnosed. METHODOLOGY This was a prospective study conducted over a six-month period from November 2012 to April 2013. A total of 308 diabetic patients were included from three diabetes centers in Abidjan (Ivory Coast). AIM To screen for PAD of the lower limbs in a diabetic population and to identify the determining factors. RESULTS Among the 308 patients, the ankle-brachial index (ABI) was<0.9 in 68 (22.07%) patients considered to have PAD; the ABI was>1.3 in 56 (18.2%) patients who had suspected mediacalcosis. The average age of the PAD patients was 60.2 years. Female gender predominated (55.9%). The mean duration of diabetes was 9.6 years: 97.1% type 2 diabetes. The other cardiovascular risk factors in this population were hypertension (58.8%) and dyslipidemia (40.9%). Smoking was present in 29.4% of patients and obesity in 23.9%. PAD of the lower limbs was mild in 46 patients (67.6%), moderate in 16 (23.5%) and severe in 6 (8.8%). Duplex Doppler commonly showed lesions of the tibial arteries. Determining factors of diabetic PAD of the lower limbs were hypertension (58.8% vs 36.6%; OR=2.46; 95% CI: 1.13-5.36; P=0.034) and dyslipidemia (40.9% vs 8.3%; OR=7.6; 95% CI: 2.31-25.08; P=0.0009). For mediacalcosis, male gender (71.5% vs 39.7; OR=0.26 95% CI/0.10-0.64. P=0.004) was the only factor identified. CONCLUSION Hypertension and dyslipidemia were predictive factors for diabetic PAD of the lower limbs in our African population.

Abstract
Phytoseiid mites are considered the most effective natural enemies of pest mites. They also have been shown to attack pest thrips. It is unknown, however, whether phytoseiid mites can reduce high densities of Thrips flavidulus (Bagnall). We addressed this question by the study of functional and numerical responses. The aim of this research was to evaluate the potential predation success of the adults of three predatory mites, Neoseiulus cucumeris (Oudemans), Neoseiulus barkeri (Hughes), and Euseius nicholsi (Ehara & Lee), against the first-instar of T. flavidulus in a climatic chamber at five different temperatures. The results showed that the functional responses of those predators reflected the Holling type II functional response and were density dependent and positively related to temperature. For the three predatory mites, predation and successful attack rates increased with increasing temperature up to 26°C, reducing afterward. Handling time had the opposite trend. Reproductive ability also increased with an increase in temperature and prey consumption.
