Growth supplements to make up for lost ground during puberty?
Your desire to try to make up for the "lost ground" is understandable. However, no scientific research backs the idea that one can physically grow substantially taller after the completion of puberty by altering what one eats. Also, there's a good chance that your eating plan (depending upon how strict a vegetarian you were) during your teenage years probably did not inhibit your height growth,...

ny cell therapy risks introducing mutated and possibly tumorigenic cells. Now results from Peter Stambrook (University of Cincinnati, Cincinnati, OH) and colleagues underline this concern for embryonic stem (ES) cells, which are one possible source for therapeutic cells. Stambrook constructed a cell line in which he could detect loss or mutation of a heterozygous marker gene. Loss (rather than ...
متن کاملA metabolic limit on the ability to make up for lost time in endurance events.
It has been repeatedly demonstrated that the tolerable duration (t) of high-intensity cycling is well characterized as a hyperbolic function of power (P) with an asymptote that has been termed the "fatigue threshold" and with a curvature constant. This hyperbolic P-t relationship has also been confirmed in running and swimming, when speed (V) is used instead of P; that is, (V - V(F)). t = D', w...
متن کاملLost to follow-up.
results gained from primary attenders at a tate review clinic after shoulder surgery may not be representative of the outcome: the average self-assessment of the non-attenders was lower by one class. Age differences have been shown to affect the self assessment of health (Idler 1993). In this study, however, with an average age of 5 1.1 years among attenders and 48.8 years in non-attenders, thi...
متن کاملArchaeal transcription: making up for lost time.
In recent years, emerging structural information on the aRNAP (archaeal RNA polymerase) apparatus has shown its strong evolutionary relationship with the eukaryotic counterpart, RNA Pol (polymerase) II. A novel atomic model of SshRNAP (Sulfolobus shibatae RNAP) in complex with dsDNA (double-stranded DNA) constitutes a new piece of information helping the understanding of the mechanisms for DNA ...
