A high-resolution study of fragment-fragment-γ triple coincident measurements of the symmetric-mass fission exit-channel from the Si+Si reaction has been performed at the VIVITRON Tandem facility by using the EUROGAM Phase II γ-ray spectrometer. The bombarding energy Elab( Si) = 111.6 MeV has been chosen to populate a well known quasi-molecular resonance in Ni. Evidence is presented for a selec...
Adam13/33 is a cell surface metalloprotease critical for cranial neural crest (CNC) cell migration. It can cleave multiple substrates including itself, fibronectin, ephrinB, cadherin-11, pcdh8 and pcdh8l (this work). Cleavage of cadherin-11 produces an extracellular fragment that promotes CNC migration. In addition, the adam13 cytoplasmic domain is cleaved by gamma secretase, translocates into ...
A very exotic process of β-delayed fission of 180Tl is studied in detail by using resonant laser ionization with subsequent mass separation at ISOLDE (CERN). In contrast to common expectations, the fission-fragment mass distribution of the post-β-decay daughter nucleus 180Hg (N/Z=1.25) is asymmetric. This asymmetry is more surprising since a mass-symmetric split of this extremely neutron-defici...
A Monte-Carlo algorithm is developed and coded in FORTRAN to calculate the energy, mass charge distribution of pre-fragments produced proton induced spallation. The based on Glauber’s theory together with a reasonable assumption type promptly emitted nucleons. For evaporation stage, correlated values pre-fragment mass, excitation energy were fed into properly modified version code MCEF (Monte-C...
The presence of Galanin and Neuropeptide Y and/or their receptors in several areas of the brain involved in memory, mood, cardiovascular control and food intake indicates that Galanin, and Neuropeptide Y could equilibrate the physiological actions of each other. There is evidence for the existence of interactions between Galanin Receptor and Neuropeptide Y Receptor in the nucleus of the solitar...
A 60-year-old male patient presenting with gradual painless progressive diminution of vision was diagnosed with nuclear sclerosis grade III (LOCS). Intra-operatively, there was a nuclear drop into the vitreous cavity. The patient was left aphakic and was deferred for further vitreoretinal procedure the next day. On first post-op day, the nucleus fragment (of roughly the same size that had dropp...
In recent years, investigations of angular distributions fragments in neutron-induced nuclear fission have been extended to intermediate energies, up 200 MeV, as well a wide range target isotopes. Using an example the latest data obtained by our group for reaction 237-Np(n,f), we discuss specific features fragment distribution and present method their simulation based on code TALYS. It is shown...
The so-called super-short fission mode, in which a nucleus divides nearly symmetrically into two unusually energetic fragments, competes favorably with the standard asymmetric mode for spontaneous of limited number nuclei near $^{264}\mathrm{Fm}$ but it quickly fades away at finite excitations. We investigate energy-dependent competition between those modes even fermium isotopes from $^{254}\ma...
