Reproductive toxicology. p-Nitrobenzoic acid.
Background. Hox genes are implicated in hematopoietic stem cell (HSC) regulation as well as in leukemia development through translocation with the nucleoporin gene NUP98. Interestingly, an engineered NUP98-HOXA10 (NA10) fusion can induce a several hundred-fold expansion of HSCs in vitro and NA10 and the AML-associated fusion gene NUP98-HOXD13 (ND13) have a virtually indistinguishable ability to...
متن کاملP-44: Oral Gibberellic Acid Administration Impact on Testicular Histochemistry
Background: Gibberellic acid (GBA) is a naturally occurring and commercially produced plant growth regulator which may cause a variety of effects including the stimulation of seed germination in some cases. Histochemical changes in testicular tissue including carbohydrates, lipids and alkaline phosphatase enzyme changes were evaluated. Materials and Methods: Twenty seven mature male rats after ...
متن کاملOn the reactivity of metallothioneins with 5,5'-dithiobis-(2-nitrobenzoic acid).
Rat liver and horse kidney metallothioneins react with 5,5'-dithiobis-(2-nitrobenzoic acid) (Nbs2) to release 5-thio-2-nitrobenzoate and metal ions. The reactions are slow and exhibit biphasic kinetics with each process having an empirical rate law of the form: rate - k[RSM] X [Nbs2] + k'[RSM], where RSM represents mental-bound thiolate groups. The pseudo-first-order rates are insensitive to pH...
متن کاملDifferentiation of Mycobacterium tuberculosis from other mycobacteria with rho-nitrobenzoic acid using MGIT960.
SETTING Mycobacteria growth in media with the addition of inhibitory substances has been used in species identification. Growth of the Mycobacterium tuberculosis complex (MTC) is inhibited by rho-nitrobenzoic acid (PNB), whereas non-tuberculous mycobacteria (NTM) are resistant. OBJECTIVE To develop a rapid PNB test using the automated BACTEC MGIT960 system and to evaluate its usefulness in th...
متن کاملUse of thiosemicarbazone and para-nitrobenzoic acid in screening tests for anonymous mycobacteria.
In screening for anonymous mycobacteria the use of thiosemicarbazone (10mug./ml.) may give rise to false positive results. Although these can usually be overcome by further tests, additional time and effort is required, which seriously limits the value of thiosemicarbazone as a true screening agent. Para-nitrobenzoic acid (500 mug./ml.) has proved more satisfactory in our hands; no false positi...
