Porcine cysticercosis, which is widely distributed in Africa, causes financial losses and diseases among humans. To control the disease in an area, it is important to know the geographical distribution. In this study, spatial distribution of porcine cysticercosis in southern Benin was performed. By using the number of partial organ seizures at meat inspection, the study has revealed high risks of porcine cysticercosis in administrative districts of Aplahoue, Dogbo, Klouekanme and Lokossa. The proportion of seizures ranged from 0.06% for neck muscles to 0.69% for tongues. Spatial analysis of carcass seizure frequencies revealed Akpro Misserete, Avrankou, Dangbo, Porto-Novo, Ifangni and Aguegues as the most likely clusters (P<0.001) for porcine cysticercosis distribution. The risk factor found to be associated with the porcine distribution was the Taenia solium cysticerci positive testing using lingual examination by butchers and retailers. Catching of pig within the Zou and Mono department and pigs directly purchased by the butcher were found protective factors for distribution of porcine cysticercosis in southern Benin. [less ▲]

The aim of this study is the experimental characterization of the behaviour of a mortar during convective drying. We focalise on mortar that has a rate water-cement of 0.5. The drying tests are developed in a micro-convective dryer that can use samples weighing from 0 to 8g. The advantage of these experiments is to reproduce the natural conditions that can be found during the treatment of the mortar-atmosphere problems. The response of the drying curve or the drying kinetic depends on the applied drying conditions. So, the temperature of the air varies from 60°C to 130°C, the velocity of the air is changed from 2 m.s-1 to 5 m. s-1and the relative humidity is kept less than 1.7%. The comparison between the experimental results and the proposed analytical solutions of the equation of diffusion represented by Fick’s law, applied for a finite shape, allows determination of the values of the diffusion coefficient. It has a value of 1.71×10-10 m2.s-1 at 60°C, 13.69×10-10 m2.s-1 at 90°C and 16.27×10-10 m2.s-1 at 130°C. Calculation of the activation energy and the D0 constant are also possible. [less ▲]

Gestational diabetes (GD) is a common complication of pregnancy. Its prevalence depends on the strategy used for screening and the studied population. Pregnant women with GD are at increased risk for maternal and fetal complications. The relationship between maternal blood sugar and complications is linear, without a clear threshold defining GD. Therefore, the diagnostic criteria for GD have been the subject of several controversies since many years. The choice of the one-step or two-step method, the test to be used and the cut-off levels validated to define GD are still debated. The same is true regarding a universal versus a at-risk population screening. International experts have recently proposed the use of a one-step approach with a 2-hour oral glucose tolerance test for a universal screening. The need for a better harmonization regarding the diagnosis of GD is indeed mandatory. The present article discusses both the advantages and disadvantages of the various approaches used for GD screening. [less ▲]

Numerous patients with type 2 diabetes have renal impairment, especially in the elderly population. Metformin, the first choice oral glucose-lowering agent, is classically contraindicated in case of chronic kidney disease of stages 3-5 (creatinine clearance < 60 ml/min/1.73 m2), because of a risk of accumulation of the biguanide that may lead to lactic acidosis. Hence numerous patients with some degree of renal impairment are being treated with metformin in clinical practice, apparently without any harm. In contrast, several observational studies have shown that they may clinically benefit from this therapy, including with a significant reduction of all-cause mortality when compared to patients not receiving metformin. Thus, an increasing number of physicians plea for revisiting the official criteria of contraindication to the use of metformin in case of renal insufficiency. The present paper discusses this controversy and insists upon the mandatory cautions to be taken when using metformin in a diabetic patient with moderate (stage 3) chronic kidney disease (metformin being contraindicated in case of severe renal impairment - stages 4-5).

Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) are oral incretin-based glucose-lowering agents with proven efficacy and safety in the management of type 2 diabetes mellitus (T2DM). In addition, preclinical data and mechanistic studies suggest a possible additional non-glycemic beneficial action on blood vessels and the heart, via both glucagon-like peptide-1-dependent and glucagon-like peptide-1-independent effects. As a matter of fact, DPP-4 inhibitors improve several cardiovascular risk factors: they improve glucose control (mainly by reducing the risk of postprandial hyperglycemia) and are weight neutral; may lower blood pressure somewhat; improve postprandial (and even fasting) lipemia; reduce inflammatory markers; diminish oxidative stress; improve endothelial function; and reduce platelet aggregation in patients with T2DM. In addition, positive effects on the myocardium have been described in patients with ischemic heart disease. Results of post hoc analyses of phase 2/3 controlled trials suggest a possible cardioprotective effect with a trend (sometimes significant) toward lower incidence of major cardiovascular events with sitagliptin, vildagliptin, saxagliptin, linagliptin, or alogliptin compared with placebo or other active glucose-lowering agents. However, the definite relationship between DPP-4 inhibition and better cardiovascular outcomes remains to be proven. Major prospective clinical trials involving various DPP-4 inhibitors with predefined cardiovascular outcomes are under way in patients with T2DM and a high-risk cardiovascular profile: the Sitagliptin Cardiovascular Outcome Study (TECOS) on sitagliptin, the Saxagliptin Assessment of Vascular Outcomes Recorded in Patients With Diabetes Mellitus-Thrombolysis in Myocardial Infarction (SAVOR-TIMI) 53 trial on saxagliptin, the Cardiovascular Outcomes Study of Alogliptin in Subjects With Type 2 Diabetes and Acute Coronary Syndrome (EXAMINE) trial on alogliptin, and the Cardiovascular Outcome Study of Linagliptin Versus Glimepiride in Patients With Type 2 Diabetes (CAROLINA) on linagliptin. If these trials confirm that a DPP-4 inhibitor can reduce the cardiovascular burden of T2DM, it would be major progress that would dramatically influence the management of the disease. [less ▲]

Glaucium flavum is used in Algerian folk medicine to remove warts (benign tumors). Its local appellations are Cheqiq el-asfar and Qarn el-djedyane. We have recently reported the anti-tumoral activity of Glaucium flavum root alkaloid extract against human cancer cells, in vitro and in vivo. The principal identified alkaloid in the extract was protopine. This study aims to determine which component(s) of Glaucium flavum root extract might possess potent antitumor activity on human cancer cells. Quantitative estimation of Glaucium flavum alkaloids was realized by HPLC-DAD. Glaucium flavum effect on human normal and cancer cell viability was determined using WST-1 assay. Quantification of alkaloids in Glaucium flavum revealed that the dried root part contained 0.84% of protopine and 0.07% of bocconoline (w/w), while the dried aerial part contained only 0.08% of protopine, glaucine as the main alkaloid, and no bocconoline. In vitro evaluation of the growth inhibitory activity on breast cancer and normal cells demonstrated that purified protopine did not reproduce the full cytotoxic activity of the alkaloid root extract on cancer cell lines. On the other hand, bocconoline inhibited strongly the viability of cancer cells with an IC50 of 7.8 µM and only a low cytotoxic effect was observed against normal human cells. Our results showed for the first time that protopine is the major root alkaloid of Glaucium flavum. Finally, we are the first to demonstrate a specific anticancer effect of Glaucium flavum root extract against breast cancer cells, which can be attributed, at least in part, to bocconoline. [less ▲]

This paper deals with the semantic and pragmatic differences between two negative coordinators in Ancient Greek, οὐδέ and οὔτε. According to the traditional view, οὔτε is a symmetrical coordinator, which links two terms without a semantic hierarchy, contrary to οὐδέ. This study tends to show that this is not the essential principle which differentiates the two coordinators, but a consequence of a more general characteristic, i.e. that the negative domain built by the two coordinators is different: with οὔτε the negative domain is unique and closed, the negated terms are contradictory ones in case of antonyms and their order is free; with οὐδέ there can be several negative domains or the negative domain is open, the negated terms are contrary ones in case of antonyms and their order depends on the argumentative goal.

This study was carried out at the animal farm of Hanoi University of Agriculture from August 2012 to April 2013 to evaluate effects of halothane genotype (CC and CT) and gender (intact males and gilts) on carcass characteristics and meat quality of Piétrain stress negative pigs. Backfat thickness, depth of longissimus dorsi muscle and lean meat percentage at 7.5 months were collected from 83 pigs (31 females and 52 intact males). Data on carcass performance were collected from 43 pigs (28 females and 15 intact males). The organoleptic quality of longissimus dorsi muscle was determined from 35 samples (19 females and 16 intact males) of longissimus dorsi muscle. For meat chemical compositions, 24 samples (14 females and 10 intact males) were analyzed. Slaughter weight (88.75 kg), carcass weight (58.40 kg), eye muscle area (57.54 cm²), backfat thickness (9.26 mm) and depth of longissimus dorsi muscle (58.01 mm) of gilts were higher than those of intact males (81.29 kg, 52.77 kg, 51.04 cm², 8.01 mm and 52.76 mm). Killing out percentage, carcass percentage and carcass length were similar between gilts and intact males (P>0.05). The pH of longissimus dorsi muscle at 24 hours post mortem between gilts (5.34) and boars (5.50) were significantly different (P<0.001). Gilts had more lipids than intact males (P<0.01). Halothane genotype did not affect carcass characteristics, meat quality and meat chemical composition (P>0.05). The results indicate that Piétrain stress negative pigs had high carcass percentage and good meat quality. Individuals with halothane genotype CC and CT can be choose for the breeding without affecting the carcass performance and meat quality [less ▲]

In order to evaluate the performance of Jatropha curcas L. in poor soil conditions, a test was conducted near Kinshasa on the Batéké plateau between July 2009 and December 2012 in the sites of Mbankana and Mongata. The results show significant differences (p < 0.05) between the treatments applied on the vegetative growth and yield. Ground cover with Stylosanthes guianensis permitted to reduce significantly the rate of fruit abortion of Jatropha and to increase the average number of seeds per capsule. The combination of pruning, mineral fertilizers application, and Stylosanthes cover improved drastically the yields obtained in the 3rd year of production compared to the control with respectively 498.73 ± 5.88 kg of dry seed ha-1 in Mbankana and 552.95 ± 5.03 kg ha-1 in Mongata. In the control plots, yields were 167.85 ± 6.57 kg ha-1 of dry seeds in Mbankana and 172.28 ± 5.96 kg ha-1 of dry seeds in Mongata. [less ▲]

Blubber samples from three delphinid species (false killer whale, Guiana and rough-toothed dolphin), as well as liver samples from franciscana dolphins were analyzed for dioxins and related compounds (DRCs). Samples were collected from 35 cetaceans stranded or incidentally captured in a highly industrialized and urbanized area (Southeast and Southern Brazilian regions). Dioxin-like PCBs accounted for over 83% of the total TEQ for all cetaceans. Non-ortho coplanar PCBs, for franciscanas (82%), and mono-ortho PCBs (up to 80%), for delphinids, constituted the groups of highest contribution to total TEQ. Regarding franciscana dolphins, significant negative correlations were found between total length (TL) and three variables, ΣTEQ-DRCs, ΣTEQ-PCDF and ΣTEQ non-ortho PCB. An increasing efficiency of the detoxifying activity with the growth of the animal may be a plausible explanation for these findings. This hypothesis is reinforced by the significant negative correlation found between TL and PCB126/PCB169 concentration ratio. DRC concentrations (ng/g lipids) varied from 36 to 3006, for franciscana dolphins, as well as from 356 to 30776, for delphinids. The sum of dioxin-like and indicator PCBs varied from 34662 to 279407 ng/g lipids, for Guiana dolphins from Rio de Janeiro state, which are among the highest PCB concentrations ever reported for cetaceans. The high concentrations found in our study raise concern not only on the conservation of Brazilian coastal cetaceans, but also on the possibility of human health problem due to consumption of fish from Brazilian estuaries.
