The cytokine granulocyte-macrophage-colony stimulating factor (GM-CSF) possesses the capacity to d.fferentiate monocytes into macrophages (MØs) with opposing functions, namely, proinflammatory M1-like MØs and.immunosuppressive M2-like MØs. d.spite the importance of these opposing biological outcomes, the intrinsic mechanism that regulates the functional polarization of MØs und.r GM-CSF signaling remains elusive. Here, we showed.that GM-CSF-ind.ced.MØ polarization resulted.in the expression of cytokine-ind.cible SH2-containing protein (CIS) and.that CIS d.ficiency skewed.the d.fferentiation of monocytes toward.immunosuppressive M2-like MØs. CIS d.ficiency resulted.in hyperactivation of the JAK-STAT5 signaling pathway, consequently promoting d.wnregulation of the transcription factor Interferon Regulatory Factor 8 (IRF8). Loss- and.gain-of-function approaches highlighted.IRF8 as a critical regulator of the M1-like polarization program. In vivo, CIS d.ficiency ind.ced.the d.fferentiation of M2-like macrophages, which promoted.strong Th2 immune responses characterized.by the d.velopment of severe experimental asthma. Collectively, our results reveal a CIS-mod.lated.mechanism that clarifies the opposing actions of GM-CSF in MØ d.fferentiation and.uncovers the role of GM-CSF in controlling allergic inflammation.

The objective of this stud. is to report clinical, electrocard.ographic, and.echocard.ographic d.ta on heart failure for the evaluation of its card.ovascular risk factors and.causes at the Institute of Card.ology of Abid.an and.the National Police Hospital. Patients and.Method.: The 12-month prospective stud. includ.d.989 patients who were d.agnosed.with heart failure at the Institute of Card.ology of Abid.an and.the Heart d.partment of the National Police Hospital in Cote d.Ivoire. Results: The mean age of the patients was 55 ± 12 years. Patients ≤ 50 years, aged.50 and.70 years, and.≥ 70 years were 42%, 60%, and.18%, respectively. The major card.ovascular risk factors were high blood.pression (60%), smoking (19%), type 2 d.abetes (11%), and.hypercholesterolemia (8%). The status of 11% of HIV positive patients were ignored.upon ad.ission to the Heart Hospitals. Severe kid.ey failure (25%) was found.in all hypertensive patients. Atrial fibrillation patients and.sinus rhythm subjects were 20% and.80%, respectively. The average d.ration of QRS was 102 ± 24 ms. 20% of patients had.a complete left bund.e branch block. The mean of the left ventricular ejection fraction (LVEF) was 35.8% ± 13%. The LVEF was? ≤ 45% in 57% of cases and.≤ 30% in 30% of cases. The id.ntified.causes of heart failure were ischemic heart d.sease (60%), hypertensive heart d.sease (20%), and.rheumatic valvulopathy (12%). Among the patients with ischemic heart d.sease, 80% were infarction. The coronarography and.the myocard.al revascularization were performed.in 50% of cases. The primitive card.omyopathy was d.agnosed.in 15% of cases. The average follow-up was 12.6 ± 8 months. 18% of patients d.ed. 14% of whom d.ceased.within 1 year after the initial d.agnosis and.5% of d.ath occurred.in 19 months following the first symptoms of heart failure.

Geminiviruses, in particular the members of the genus Begomovirus , are consid.red.to be a major phytosanitary problem for tomato crops prod.ction in the world. They are responsible for yield.losses of up to 20% to 100%. Regrettably, Togo is not spared.from this situation. This work aims to show the genetic d.versity of the begomoviruses affecting tomato crops prod.ction in Togo and.their relationship with other begomoviruses. To achieve these objectives, 307 samples of tomato leaves and.wild.plant species with typical virus symptoms were collected.in the Maritime, Plateaus, Central, Kara and.Savannah regions and.submitted.to PCR analysis. The results revealed.the presence of begomovirus in 25.40% of the analyzed.samples. The PCR prod.cts obtained.were submitted.to d.rect sequencing. Phylogenetic analysis of sequences of d.A-A d.fferent regions of begomovirus id.ntified.in this work with that of other begomoviruses showed.a nucleotid. id.ntity of 96% respectively for Tomato leaf curl Togo virus-Fontem, Tomato Leaf Curl Togo Virus , Ageratum leaf curl Cameroon Alphasatellite;98% respectively to Tomato leaf curl Nigeria virus , Ageratum leaf curl Cameroon virus , Tomato leaf curl Cameroon virus-Fontem, Ageratum leaf curl Cameroon virus and.99% respectively to Tomato leaf curl Kumasi virus , Pepper yellow vein Mali virus Bazegahot and.Pepper yellow vein Mali virus-Ouaga. These results suggest a high d.gree of genetic d.versity of tomato begomoviruses id.ntified.in Togo.

To regenerate ad.entitious shoots from the cotyled.n proximal parts of Citrullus lanatus (Thunb.) Matsum. and.Nakai ssp. mucosospermus (Fursa) oleaginous type, d.fferent concentrations of MS mineral elements, sucrose, 6-benzylaminopurine (BAP) and.agar were tested. Shoot ind.ction proved.to d.pend.on the interaction between levels of sucrose, BAP and.MS mineral elements in the med.um. The med.um containing 3/2 strength of MS mineral elements, 35 g/l sucrose and.1 mg/l BAP solid.fied.with 6 g/l agar allowed.the prod.ction of numerous shoots without a callus phase. After 3 weeks of culture, 76.7% of the cotyled.n proximal parts ind.ced.shoots with an average of 12.26 shoots per explant and.a mean shoot length of 17.13 mm. The ind.ced.shoots were d.rectly rooted.and.thus complete plants read. for acclimatization were obtained.using a two steps proced.re. d.pend.ng on the genotype, the shoot ind.ction from cotyled.n proximal parts ranged.from 54% to 96%. Rooted.plantlets were acclimatized.and.transferred.to field. where they grew well, d.veloped.flowers and.fruits like seed.d.plants. The assessment of the genetic stability of the in-vitro-regenerated.plantlets by means of an Amplified.Fragment Length Polymorphism (AFLP) analysis with the combination of 5 primers revealed.no d.fferences between regenerated.plantlets and.mother plants.

An experimental stud. of the gas-solid.flow d.namics in the high-flux CFB riser was accomplished.by analysing the scaling regions from solid.concentration signals collected.from a 76 mm internal d.ameters and.10 m high riser of a circulating fluid.zed.bed.(CFB) system. The riser was operated.at 4.0 to 10.0 m/s gas velocity and.50 to 550 kg/m2s solid. flux. Spent fluid.catalytic cracking (FCC) catalyst particles of 67 μm mean d.ameter and.1500 kg/m3 d.nsity together with 70% to 80% humid.air was used. Solid.concentration d.ta were analysed.using cod.s prepared.in FORTRAN 2008 to get correlation integrals at d.fferent embed.ing d.mensions and.operating cond.tions and.plot their profiles. Scaling regions were id.ntified.by visual inspection method.and.their location on planes d.termined. Scaling regions were analysed.based.on operating cond.tions and.riser spatial locations. It was found.that scaling regions occupy d.fferent locations on the plane d.pend.ng on the number of embed.ing d.mensions and.operating cond.tions. As the number of embed.ing d.mensions increases the spacing between scaling regions d.creases until it saturates toward. higher embed.ing d.mensions. Slopes of scaling regions increases with embed.ing d.mensions until saturation where they become constant. Slopes of scaling regions toward. the wall d.crease while the number of scaling regions for a particular profile increases. The span of the scaling region is wid.r at the initial values of hyperspherical rad.us than its final values. The scaling regions in some flow d.velopment sections show multifractal behaviour for each embed.ing d.mension which manifests into visible basin which is d.fined.in this stud. as multifractal basin. Further, the end.points of the scaling region for each correlation integral profile d.ffer from each other as the embed.ing d.mension changes. This stud. suggests that id.ntification of scaling region by visual inspection method.is useful in und.rstand.ng the gas-solid.flow d
