Some of the most exciting recent advances in conducting polymer synthesis have centered around the method of vapor phase polymerization (VPP) of thin films. However, it is not known whether the VPP process can proceed using significantly reduced volumes of oxidant and therefore be implemented as part of nanolithography approach. Here, we present a strategy for submicrometer scale patterning of ...

Since ancient times, beautiful skin, firm nails and shiny hairs which look good and live young, has had a strong desire for humans. To maintain health and natural beauty as long as possible and to delay the aging process, continuous supply of some nutrients is necessary in the body. Our metabolism is reflected on the skin, which is sensitive to any change that happens. From inside of a body, th...

In this paper it is shown that within a Combined Genetic Code Table, realized through a combination of Watson-Crick Table and Codon Path Cube it exists, without an exception, a strict distinction between two classes of enzymes aminoacyl-tRNA synthetases, corresponding two classes of amino acids and belonging codons. By this, the distinction itself is followed by a strict balance of atom number ...

The paper considers the task of identifying a causal linear dynamic system excited by stationary gaussian zero mean noise of unknown spectrum, and given measurements of the system input and output contaminated by independent additive stationary noise 91g0813 of unknown spectra. While the solution is normally not unique, finite-dimensional parameterizations of the solution set are given (in some...

The information conveyed by the sequence of the four main nucleotides in genes (the genetic code) is used to order the sequence of the 20 different amino acids in proteins. In this process the four letter nucleotide code is translated into the 20 letter amino acid alphabet. Until several years ago, there existed much confusion about the molecular basis of the reading of the genetic code. Now, h...

Rat growth repression caused by the presence in the diet of an unusually high concentration of certain individual amino acids has been reported (Hier et al., 1944; Graham et at., 1950; Niven et al., 1946; Martin, 1947; Van Pilsutm and Berg, 1950; Wretlind and Rose, 1950; Russel et al., 1952). It has been suggested that such repression may be due to amino acid imbalance (Hier et al., 1944) or th...

We report the dietary intake of selected nutrients in apparently healthy adults and children and its correlation with circulating levels of serum leptin and resistin. In this observational study, 47 Saudi children (mean age 13.1 ± 2.8 year) and 47 adults (mean age 45.7 ± 10.5 year) were recruited. Anthropometric data and lipid profile were obtained. Food intake was assessed by a food questio...

Aberrant alterations in glucose and lipid concentrations and their pathways of metabolism are a hallmark of diabetes. However, much less is known about alterations in concentrations of amino acids and their pathways of metabolism in diabetes. In this review we have attempted to highlight, integrate and discuss common alterations in amino acid metabolism in a wide variety of cells and tissues an...

Alignments of orthologous protein sequences convey a complex picture. Some positions are utterly conserved whilst others have diverged to variable degrees. Amongst the latter, many are non-exchangeable between extant sequences. How do functionally critical and highly conserved residues diverge? Why and how did these exchanges become incompatible within contemporary sequences? Our model is phosp...
