Reproduction in domestic animal is a very complex process. The process starts from gamete formation, release, transport, fertilization, embryo and fetal development until delivery of the offspring by dam. holds most important role determining success livestock farming, profit or loss. genetic selection reproductive traits became an program to find out merit candidate dam bulls. At early time, f...

Triton X-100-treated sperms were injected into non-nucleate egg fragments of Xenopus laevis to determine whether the structure of the injected sperm nucleus is affected by the cyclic activity of the cytoplasm. Swollen vesicular nuclei were very frequently observed when the sperms were injected and incubated during the 'rounding-up' phase of the recipient fragment, whereas no such structures wer...

Nuclear RNAs, pulse-labeled with [methyl-3H]methionine and [3H]uridine under optimal conditions, were prepared from cells infected with simian virus 40 at a late time after infection. The labeled RNAs were hybridized with restriction fragments of simian virus 40 DNA. Levels of methyl-3H-labeled RNA annealing with the early (E) or late (L) strands of a particular restriction fragment were compar...

The large body of experimental data on nuclear fission is analyzed with a semiempirical ordering scheme based on the macro-microscopic approach and the separability of compound-nucleus and fragment properties on the fission path. We apply the statistical model to the non-equilibrium descent from saddle to scission, taking the influence of dynamics into account by an early freeze out. The presen...

Percutaneous disc surgery, also known as percutaneous discectomy (PD), for herniated nucleus pulposus (HNP) was introduced by Hijikata [1] in Japan. Indeed, as compared with traditional disc surgery such as love’s procedure, PD is minimally invasive since it can be performed under local anesthesia. However, Hijikata’s technique does not use a spinal endoscope; thus, its reliability for the remo...

Experimental studies of the break up of light nuclear projectiles in the Coulomb field of a heavy nucleus, acting as a source of virtual photons, are proposed as an access to information about the reverse reaction, the fusion of the fragment particles at small relative energies. The mechanism of Coulomb dissociation is studied and the cross section of such reactions, being potentially of astrop...

The nuclear factor κB (NF-κB) transcription factor is a master regulator of inflammation. Short-term NF-κB activation is generally beneficial. However, sustained NF-κB might be detrimental, directly causing apoptosis of cells or leading to a persistent damaging inflammatory response. NF-κB activity in stressed cells needs therefore to be controlled for homeostasis maintenance. In mildly stresse...

Abstract In this paper, we report a detailed study on the de-excitation of 46 Ti compound nucleus populated by means four different reactions: 16 O + 30 Si at 7 and 8 AMeV, 18 28 AMeV 19 F 27 Al AMeV. The GARFIELD detection array was used to measure light charged particles heavy fragments emitted. This setup covers large fraction solid angle with high-granularity. Complete events are chosen thr...

gamma aminobutyrate (gaba) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. mechanisms by which gaba may facilitate these responses to stress are metabolic and/or mechanical disruptions. environmental stresses increase gaba accumulation through cytosolic acidification, induce an acidic ph-dependent activation of glutamate...

Recently the number of hadron therapy facilities has been increasing rapidly. Some of them are designed for heavy ions and need a tool to simulate the passage of ions through matter. As well, the space engineering field requires good estimates of device damage caused by bombarding ions in cosmic rays. As a result, demands for detailed simulations of nucleus-nucleus interactions have increased. ...
