A mathematical model of mortality dynamics across the lifespan combining heterogeneity and stochastic effects
submitted by omolfansad 14 minutes ago - Topic: Health
The mortality patterns in human populations reflect biological, social and medical factors affecting our lives, and mathematical modelling is an important tool for the analysis of these patterns. It is known that the mortality rate in all human populations increases with age after sexual maturity...



Effect of Head-to-Head Addition in Vinyl Acetate Controlled Radical Polymerization: Why Is Co(acac)2-Mediated Polymerization so Much Better?
submitted by lesdo 16 minutes ago - Topic: Health
The controlled polymerization of vinyl acetate has been recently achieved by several techniques, but PVAc with targeted Mn and low dispersity up to very high monomer conversions and high degrees of polymerization was only obtained with Co(acac)2 as controlling agent in the so-called CMRP, a type ...

Rheological Behavior of Environmentally Friendly Castor Oil-Based Waterborne Polyurethane Dispersions
submitted by lesdo 16 minutes ago - Topic: Health
Novel biorenewable, waterborne, castor oil-based polyurethane dispersions (PUDs) were successfully synthesized via homogeneous solution polymerization in methyl ethyl ketone followed by solvent exchange with water. Small-amplitude oscillatory shear flow experiments were used to systematically inv...

Dynamics of Macromolecules Grafted in Spherical Brushes under Good Solvent Conditions
submitted by lesdo 16 minutes ago - Topic: Health
Spherical polymer brushes have a structure intermediate between star polymers and polymer brushes on flat substrates, and are important building blocks of polymer nanoparticles. Molecular dynamics simulations are presented for isolated spherical polymer brushes under good solvent conditions, vary...

Optimization of regeneration and Agrobacterium-mediated transformation of immature cotyledons of chickpea (Cicer arietinum L.)
submitted by lenogholeb 16 minutes ago - Topic: Biology
Immature cotyledons collected at different time intervals from four genotypes of chickpea (C 235, BG 256, P 362 and P 372) were cultured adaxially on Murashige and Skoog (MS) medium supplemented with 6-benzyladenine, thidiazuron, kinetin, zeatin and dimethylallylaminopurine (2-iP), either alone o...



Recurrent somatic embryogenesis and plant regeneration from immature zygotic embryos of cabbage (Brassica oleracea var. capitata) and cauliflower (Brassica oleracea var
submitted by lenogholeb 16 minutes ago - Topic: Biology
A simple and rapid protocol was established for repetitive somatic embryogenesis and subsequent plant regeneration in two important Brassica oleracea varieties, cabbage and cauliflower. Direct regeneration of somatic embryos (SEs) was achieved from immature zygotic embryos cultured on B5 plant gr...

Influence of salicylic acid and methyl jasmonate elicitation on anthocyanin production in callus cultures of Rosa hybrida L
submitted by lenogholeb 16 minutes ago - Topic: Biology
This study was undertaken to investigate the effects of salicylic acid (SA) and methyl jasmonate (MeJA) on anthocyanin induction, biomass accumulation, and color value (CV) indices for both pigment content (PC) and pigment production (PP) in callus cultures of Rosa hybrida cv. Pusa Ajay. A concen...

Shoot organogenesis in three Miscanthus species and evaluation for genetic uniformity using AFLP analysis
submitted by lenogholeb 16 minutes ago - Topic: Biology
A simple, efficient protocol for direct in vitro shoot organogenesis and regeneration was established for three species of Miscanthus including two clones of Miscanthus x giganteus, one clone of M. sinensis and one clone of M. sacchariflorus. Shoots were induced from the axillary nodes of both M....

Doubled haploids of novel trigenomic Brassica derived from various interspecific crosses
submitted by lenogholeb 16 minutes ago - Topic: Biology
To develop doubled haploid (DH) mapping populations of hexaploid Brassica, 10 F1 hybrids derived from crosses between allohexaploid Brassica parents were evaluated in this study. The allohexaploid Brassica parents were selfed progenies of unique interspecific crosses between Brassica rapa (genome...

Immunogenicity of a lettuce-derived vaccine candidate expressing the E2 protein against classical swine fever virus
submitted by lenogholeb 16 minutes ago - Topic: Biology
Classical swine fever (CSF) is a highly infectious hemorrhagic disease that affects domestic and wild swine. Live attenuated vaccines for classical swine fever viruses (CSFV) can provide rapid onset protection against CSF. However, because of serious safety concerns regarding the use of modified-...

A case report: endoscopic enucleation of gastrointestinal stromal tumor of the ampulla of Vater
submitted by drroe 26 minutes ago - Topic: Health
To report a case of endoscopic enucleation of a gastrointestinal stromal tumor of the ampulla of Vater.The tumor resection was performed by needle knife endoscopic submucosal dissection.The tumor was resected completely without serious complications and the patient recovered rapidly.Endoscopic en...

In vivo fertilising ability of frozen-thawed boar sperm treated with cholesterol-loaded cyclodextrins prior to cryopreservation
submitted by loaryon 27 minutes ago - Topic: Agriculture
The use of frozen-thawed (FT) sperm for the artificial insemination of pigs is rare. Treating boar sperm with cholesterol-loaded cyclodextrins (CLC) prior to cryopreservation enhances the penetration of immature oocytes in vitro, and this phenomenon has been positively correlated with in vivo fer...

Mycosis fongoïde papuleux
submitted by gorfeildcot8338 31 minutes ago - Topic: Health
MFP), dont dix cas ont été rapportés dans la littérature médicale. Le MFP débute par une éruption papuleuse, érythémateuse, non prurigineuse et chronique qui ne s’associe pas aux lésions érythématosquameuses classiques de MF débutant. Il ne semble pas exister de prédominance de se...

Long–term trends of upwelling and impacts on primary productivity in the Alaskan Beaufort Sea
submitted by tomobatt 31 minutes ago - Topic: Geography
Using a previously established wind proxy for upwelling along the North Slope of Alaska, we examine the interannual to decadal variability in upwelling as well as the climatological monthly trends. The ability of the upwelling to trigger phytoplankton blooms via upward nitrate flux from the haloc...
