Methiozolin sorption and mobility in sand-based root zones.
Flessner ML, Wehtje GR, McElroy JS, Howe JA. Flessner ML, et al. Pest Manag Sci. 2015 Aug;71(8):1133-40. doi: 10.1002/ps.3896. Epub 2014 Oct 18. Pest Manag Sci. 2015. PMID: 25174500
RESULTS: Sorption coefficients (Kd values) ranged from 0.4 to 29.4 mL g(-1) and averaged 13.8 mL g(-1) . Sorption was most influenced by organic matter content; conversely, soil pH had a negligible effect. ...

Effects of the Immunocontraceptive Gonacon on Pregnancy in Brucella-Seropositive American bison (Bison bison).
Frey RK, Wehtje ME, Nol P, Clarke PR, Rhyan JC, McCollum MP, Miller LA, Eckery DC. Frey RK, et al. J Wildl Dis. 2024 Apr 1;60(2):339-345. doi: 10.7589/JWD-D-21-00168. J Wildl Dis. 2024. PMID: 38373061
The purpose of this study was to determine if the number of pregnancies in naturally infected Brucella abortus-positive bison (Bison bison) cows would be reduced over a period of 5 yr after one treatment with 3000 g gonadotropin-releasing hormone immunocontraceptive (GonaC …

Multistate Infestation with the Exotic Disease-Vector Tick Haemaphysalis longicornis - United States, August 2017-September 2018.
Beard CB, Occi J, Bonilla DL, Egizi AM, Fonseca DM, Mertins JW, Backenson BP, Bajwa WI, Barbarin AM, Bertone MA, Brown J, Connally NP, Connell ND, Eisen RJ, Falco RC, James AM, Krell RK, Lahmers K, Lewis N, Little SE, Neault M, Pérez de León AA, Randall AR, Ruder MG, Saleh MN, Schappach BL, Schroeder BA, Seraphin LL, Wehtje M, Wormser GP, Yabsley MJ, Halperin W. Beard CB, et al. MMWR Morb Mortal Wkly Rep. 2018 Nov 30;67(47):1310-1313. doi: 10.15585/mmwr.mm6747a3. MMWR Morb Mortal Wkly Rep. 2018. PMID: 30496158 Free PMC article.
Improved activity retention of enzymes deposited on solid supports.
Wehtje E, Adlercreutz P, Mattiasson B. Wehtje E, et al. Biotechnol Bioeng. 1993 Jan 20;41(2):171-8. doi: 10.1002/bit.260410202. Biotechnol Bioeng. 1993. PMID: 18609535
Decreased stability of the enzyme preparations was noticed when low enzyme loadings were used (e.g., with Celite as support; less than 1 mg enzyme/g). It was possible to avoid the activity loss by the addition of an additive which protects the enzyme during the immo …

Effect of mass-transfer limitations on the selectivity of immobilized alpha-chymotrypsin biocatalysts prepared for use in organic medium.
Barros RJ, Wehtje E, Adlercreutz P. Barros RJ, et al. Biotechnol Bioeng. 2000 Feb 5;67(3):319-26. Biotechnol Bioeng. 2000. PMID: 10620262
Using a small molecule (AlaNH(2)) as nucleophile, the onset of these limitations caused only minor reductions in selectivity, while when using a larger nucleophilic species (AlaPheNH(2)) it was reduced by up to 60% when increasing enzyme loading on Celite from 2 to 100 mg/g …

Calorimetric studies on solid alpha-chymotrypsin preparations in air and in organic solvents.
Oste-Triantafyllou A, Wehtje E, Adlercreutz P, Mattiasson B. Oste-Triantafyllou A, et al. Biochim Biophys Acta. 1996 Jun 7;1295(1):110-8. doi: 10.1016/0167-4838(96)00036-2. Biochim Biophys Acta. 1996. PMID: 8679668
The presence of isooctane resulted in a remarkable stabilization of the chymotrypsin-sorbitol complex. A sorbitol concentration of 5 mmol/g of protein was prerequisite to induce stabilization when equilibrated through isooctane at high water activities. ...
