Pereira M, Toniello G, Souza K, Horowitz F
Opt Lett . 2019 Sep; 44(18):4539-4541. PMID: 31517925
The optical performance of very thin films has always been difficult to measure, and it has been a gray area due to interface and coating imperfections. Atomic layer deposition has...

Aires M, Santos J, Souza K, Farias P, Santos A, Fioretto E, et al.
Braz J Med Biol Res . 2015 Jul; 48(8):676-82. PMID: 26176314
The function of the visceral yolk sac (VYS) is critical for embryo organogenesis until final fetal development in rats, and can be affected by conditions such as diabetes. In view...

Hooper D, Wolfson J, Tung C, Souza K, SWARTZ M
J Bacteriol . 1989 Apr; 171(4):2235-7. PMID: 2539364
Antagonism of the DNA gyrase B subunit in the donor bacterium by coumermycin or thermal inactivation inhibited transfer of plasmid R64drd-11. Coumermycin also inhibited Hfr transfer, with kinetics after drug...

Hooper D, Wolfson J, Souza K, Ng E, McHugh G, SWARTZ M
Antimicrob Agents Chemother . 1989 Mar; 33(3):283-90. PMID: 2658782
Two genetic loci selected for norfloxacin (nfxB) and ciprofloxacin (cfxB) resistance were characterized. Both mutations have previously been shown to confer pleiotropic resistance to quinolones, chloramphenicol, and tetracycline and to...

Cohen S, Hooper D, Wolfson J, Souza K, McMurry L, Levy S
Antimicrob Agents Chemother . 1988 Aug; 32(8):1187-91. PMID: 3056253
Escherichia coli was shown to have an energy-dependent reduced uptake of the fluoroquinolone antimicrobial agent norfloxacin. Studies of everted inner membrane vesicles suggested that this reduced accumulation involved a carrier-mediated...

Wolfson J, Hooper D, Ng E, Souza K, McHugh G, SWARTZ M
Antimicrob Agents Chemother . 1987 Nov; 31(11):1861-3. PMID: 2829717
The mechanism of action of the quinolone analogs ofloxacin and S-25930, which are unusual because of the presence of a third ring with an asymmetric carbon, was studied. Drug-resistant strains...

Hooper D, Wolfson J, Souza K, Tung C, McHugh G, SWARTZ M
Antimicrob Agents Chemother . 1986 Apr; 29(4):639-44. PMID: 3010850
In Escherichia coli the frequency of spontaneous single-step mutation to high levels of resistance to the newer 4-quinolone agent norfloxacin was confirmed to be over 300-fold lower than that to...
