Rat brain SAM levels were markedly increased after methionine administration, whereas the convulsant, L-methionine-dl-sulphoximine (MSO), produced a 35 per cent decrease in whole brain content of S-adenosyl-L-methionine (SAM). When methionine was given in combination with MSO, SAM levels were not decreased. Studies on the regional distribution of SAM revealed only a small variation between regi...

It is widely accepted that elevated plasma total homocysteine is an independent risk factor for vascular disease. The relation is believed to be causal, but there is no generally accepted mechanism for the pathophysiology involved. The metabolic precursor of homocysteine in all tissues is S-adenosylhomocysteine (AdoHcy). AdoHcy is present in normal human plasma at concentrations approximately 1...

We investigate S-boxes defined by pairs of Orthogonal Cellular Automata (OCA), motivated the fact that such CA always define bijective vectorial Boolean functions, and could thus be interesting for design block ciphers. In particular, we perform an exhaustive search all nonlinear OCA diameter $$d=4$$ $$d=5$$ , which generate size $$6\times 6$$ $$8\times 8$$ respectively. Surprisingly, these tur...

Background: Neurofollicular hamartoma (NFH) is characterized histopathologically by fascicles of spindle cells that laterally delimited by hyperplastic folliculosebaceous units. It usually appears on face, near the nose or nasolabial fold. It does not manifest true neural differentiation and recently the term spindle cell predominant trichodiscoma (SCPT) has been used instead. Case Presentatio...

Cells that make up the bodychr('39')s tissues are usually three-dimensional architecture, the threedimensional culture system enables cells to create natural and in vivo interactions which is an ideal environment for 3D (Three-dimensional) cell growth and issues such as exchange of similar food exchanges inside Capillary in living tissue. In tissue engineering discussion, cell scaffolding is hi...
