A facile and efficient one-pot synthesis of pyrrolidines and dispiro pyrrolidines/pyrrolizidines has been accomplished by the 1,3-dipolar cycloaddtion reaction of azomethine ylides generated insitu from paraformaldehyde/ninhydrin and secondary amino acids with electron-deficient dipolarophiles in good yield. The reaction proceeded with high regio and stereoselectivity. The products have been ch...

species, and the transient localised fluctuation that may be anticipated for both pH and ROS. Therefore, the development and implementation of methodologies to allow the real-time insitu analysis of biomarkers, such as pH and ROS, may offer huge advantages in terms of our understanding of how the biomarkers change throughout normal and pathological healing processes, and provide a better insigh...

Pregnancy in non – communicating rudimentary horn is very rare. Here is a case of 24 year old woman presenting with pain abdomen. After clinical, sonological and MRI scan revealed pregnancy in non – communicating rudimentary horn. Since it is acute abdomen, the patient was operated and excision of the rudimentary horn with pregnancy insitu. Timely intervention saved the woman’s life, thus preve...

metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...

This article reviews recent progress in the development of ferrocene (Fc)-modified thin films and nanoparticles in relation to their biosensor applications. Redox-active materials in enzyme biosensors commonly use Fc derivatives, which mediate electron transfer between the electrode and enzyme active site. Either voltammetric or amperometric signals originating from redox reactions of Fc are de...

We found ENDF/B-VIII.0 caused the following problems through our analyses of iron insitu experiment at JAEA/FNS; 1) neutron flux 1 - 10 keV is overestimated more in shallower region assembly, 2) reaction rate 115In (n,n’)115mIn underestimated deeper region, 3) above MeV region. The reasons for these were investigated detail and it was specified that inelastic scattering data 56Fe ENDF/BVIII. 0 ...

Bone comprises a complex structure of primarily collagen, hydroxyapatite and water, where each hierarchical structural level contributes to its strength, ductility and toughness. These properties, however, are degraded by irradiation, arising from medical therapy or bone-allograft sterilization. We provide here a mechanistic framework for how irradiation affects the nature and properties of hum...
