Effects of Elevated Carbon Dioxide and Chronic Warming on Nitrogen (N)-Uptake Rate, -Assimilation, and -Concentration of Wheat.
Jayawardena DM, Heckathorn SA, Boldt JK. Jayawardena DM, et al. Plants (Basel). 2020 Dec 1;9(12):1689. doi: 10.3390/plants9121689. Plants (Basel). 2020. PMID: 33271885 Free PMC article.
To investigate this, spring wheat (Triticum aestivum) was grown for three weeks at two levels of CO(2) (400 or 700 ppm) and two temperature regimes (26/21 or 31/26 C, day/night). Plant dry mass, plant %N, protein concentrations, NO(3)(-) and NH(4)(+) root uptake rates (usi …

Elevated carbon dioxide plus chronic warming causes dramatic increases in leaf angle in tomato, which correlates with reduced plant growth.
Jayawardena DM, Heckathorn SA, Bista DR, Boldt JK. Jayawardena DM, et al. Plant Cell Environ. 2019 Apr;42(4):1247-1256. doi: 10.1111/pce.13489. Epub 2019 Jan 18. Plant Cell Environ. 2019. PMID: 30472733 Free article.
To characterize this phenomenon, tomato plants were grown at two levels of CO(2) (400 vs. 700 ppm) and two temperature regimes (30 vs. 37C) for 16-18 days. Leaf hyponasty increased dramatically with warming plus eCO(2) but increased only slightly with either factor alone a …

Catheter ablation of atrial flutter: A survey focusing on post ablation oral anticoagulation management and ECG monitoring.
Attanasio P, Budde T, Lacour P, Parwani AS, Pieske B, Blaschke F, Haverkamp W, Boldt LH, Huemer M. Attanasio P, et al. Pacing Clin Electrophysiol. 2017 Jul;40(7):788-793. doi: 10.1111/pace.13122. Epub 2017 Jun 16. Pacing Clin Electrophysiol. 2017. PMID: 28548234

Elevated CO2 plus chronic warming reduce nitrogen uptake and levels or activities of nitrogen-uptake and -assimilatory proteins in tomato roots.
Jayawardena DM, Heckathorn SA, Bista DR, Mishra S, Boldt JK, Krause CR. Jayawardena DM, et al. Physiol Plant. 2017 Mar;159(3):354-365. doi: 10.1111/ppl.12532. Epub 2017 Jan 19. Physiol Plant. 2017. PMID: 27893161
In this study, tomato (Solanum lycopersicum) plants were grown at two levels of CO(2) (400 or 700 ppm) and two temperature regimes (30 or 37C), with NO(3)(-) or NH(4)(+) as the N source. Elevated CO(2) plus chronic warming severely inhibited plant growth, regardless of N f …

A Single Institution Consensus on the Use of Sequential or Concurrent Hormonal Therapy for Breast Cancer Patients Receiving Radiation Therapy.
Cecchini MJ, Yu E, Yaremko BP, Boldt RG, Potvin K, Sexton T, D'Souza D, Brackstone M, Lock M. Cecchini MJ, et al. Cureus. 2016 Apr 3;8(4):e555. doi: 10.7759/cureus.555. Cureus. 2016. PMID: 27182469 Free PMC article.
The ideal timing of hormonal and radiation treatment is not well defined, and there is a significant degree of practice variability between concurrent and sequential treatment regimes. This variability can cause confusion amongst the clinical team resulting in contradictor …

Observed latitudinal variations in erosion as a function of glacier dynamics.
Koppes M, Hallet B, Rignot E, Mouginot J, Wellner JS, Boldt K. Koppes M, et al. Nature. 2015 Oct 1;526(7571):100-3. doi: 10.1038/nature15385. Nature. 2015. PMID: 26432248
Although this broad region has a relatively uniform tectonic and geologic history, the thermal regimes of its glaciers range from temperate to polar. We find that basin-averaged erosion rates vary by three orders of magnitude over this latitudinal transect. Our findings im …

Perioperative management of patients with impaired left ventricular function.
Boldt J. Boldt J. Curr Opin Anaesthesiol. 1998 Jun;11(3):315-9. doi: 10.1097/00001503-199806000-00014. Curr Opin Anaesthesiol. 1998. PMID: 17013239
Knowledge of pre-existing cardiac disease and of haemodynamic principles are prerequisites for selecting an appropriate therapeutic regime. This appears to be more important for successfully treating acute perioperative myocardial failure than waiting for a new 'magic' sub …

Influence of different volume therapies on platelet function in the critically ill.
Boldt J, Müller M, Heesen M, Heyn O, Hempelmann G. Boldt J, et al. Intensive Care Med. 1996 Oct;22(10):1075-81. doi: 10.1007/BF01699231. Intensive Care Med. 1996. PMID: 8923073 Retracted. Clinical Trial.
OBJECTIVE: Both albumin and synthetic colloids such as hydroxyethyl starch (HES) solution are used to optimize hemodynamics in the critically ill. The influence of different long-term infusion regimes on platelet function was studied. DESIGN: Prospective, randomized study. …
