Which of the charges (in chemistry, physics, electricity) is stronger, positive or negative? For example, if we have more negative than positive charge, the one that will be dominant is the negative or the positive charge cancels any negative charge? (I have the same question about having more positive than negative) 93.126.116.89 ( talk) 05:19, 18 September 2018 (UTC)
Although the negative and positive charges are equal and opposite fundamentally, as per the above discussion, in chemistry, it's quite often the case that the negative charges of the electron cloud are felt more strongly than the positive charges of the nucleus. This is because the electrons are on the outside, so they form a shield around the nucleus. This is discussed under the subjects of electron shielding and effective nuclear charge. The latter article shows that for neutral atoms, increasing charge of the nucleus by one results in less than one additional charge being felt outside the electron cloud. Neon for example has 10 positive charges (and 10 negative charges) but a charge of only +5.758 is felt by the outermost electrons. Handschuh- talk to me 10:45, 22 September 2018 (UTC)
Have there been any predictions/projections on when we will be able to regrow human skin and thus completely eliminate white scars? Futurist110 ( talk) 20:01, 18 September 2018 (UTC)
I found the manufacturer who mentions CTGF, and cites [3]. The design of the modified asymmetric siRNA is given in this appendix. The actual substance is therefore the annealed combination of
Where mN = 2’ - OMe modified nucleotide, (s) = phosphorothioate, and -chol = cholesterol.
If this holds up, it is not merely a medical advance, but also a big technical step forward in siRNA technology, with applications to a vast number of target genes. And, this should be a type of drug fairly readily manufactured on an illicit basis by those with the will to do so, making it potentially accessible to the common people.
