Factors affecting high-oxygen survival of heterotrophic microorganisms from an antarctic lake.

Applied and environmental microbiology

Mikell AT, Parker BC, Gregory EM.
PMID: 16347231
Appl Environ Microbiol. 1986 Dec;52(6):1236-41. doi: 10.1128/aem.52.6.1236-1241.1986.

We sought to determine factors relating to the survival of heterotrophic microorganisms from the high-dissolved-oxygen (HDO) waters of Lake Hoare, Antarctica. This lake contains perpetual HDO about three times that of normal saturation (40 to 50 mg liter). Five...

Influence of thyroid hormones on the GH-IGF-I axis.

Trends in endocrinology and metabolism: TEM

Rodriguez-Arnao J, Miell JP, Ross RJ.
PMID: 18407153
Trends Endocrinol Metab. 1993 Jul;4(5):169-73. doi: 10.1016/1043-2760(93)90107-p.

There is a complex relationship between thyroid hormones, GH, and the insulin-like growth factors (IGFs). Thyroid hormones act at many sites from the hypothalamic control of GH release to the tissue expression of IGF-I and its binding proteins (IGFBPs)....

Happiness unpacked: positive emotions increase life satisfaction by building resilience.

Emotion (Washington, D.C.)

Cohn MA, Fredrickson BL, Brown SL, Mikels JA, Conway AM.
PMID: 19485613
Emotion. 2009 Jun;9(3):361-8. doi: 10.1037/a0015952.

Happiness-a composite of life satisfaction, coping resources, and positive emotions-predicts desirable life outcomes in many domains. The broaden-and-build theory suggests that this is because positive emotions help people build lasting resources. To test this hypothesis, the authors measured emotions...

Age-related Changes in Lateral Entorhinal and CA3 Neuron Allocation Predict Poor Performance on Object Discrimination.

Frontiers in systems neuroscience

Maurer AP, Johnson SA, Hernandez AR, Reasor J, Cossio DM, Fertal KE, Mizell JM, Lubke KN, Clark BJ, Burke SN.
PMID: 28713251
Front Syst Neurosci. 2017 Jun 30;11:49. doi: 10.3389/fnsys.2017.00049. eCollection 2017.

Age-related memory deficits correlate with dysfunction in the CA3 subregion of the hippocampus, which includes both hyperactivity and overly rigid activity patterns. While changes in intrinsic membrane currents and interneuron alterations are involved in this process, it is not...

Allred JD, Niedbala J, Mikell JK, Owen D, Frey KA, Dewaraja YK.
PMID: 29904808
EJNMMI Res. 2018 Jun 15;8(1):50. doi: 10.1186/s13550-018-0402-8.

BACKGROUND: A major toxicity concern in radioembolization therapy of hepatic malignancies is radiation-induced pneumonitis and sclerosis due to hepatopulmonary shunting of RESULTS: A liver/lung torso phantom filled with CONCLUSIONS: The improved accuracy demonstrated by the phantom study, agreement with

Acute Gastrointestinal Injury and Feeding Intolerance as Prognostic Factors in Critically Ill COVID-19 Patients.

Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract

Drakos P, Volteas P, Cleri NA, Alkadaa LN, Asencio AA, Oganov A, Pryor A, Talamini M, Rubano J, Bannazadeh M, Mikell CB, Spaniolas K, Mofakham S.

BACKGROUND: Although acute gastrointestinal injury (AGI) and feeding intolerance (FI) are known independent determinants of worse outcomes and high mortality in intensive care unit (ICU) patients, the incidence of AGI and FI in critically ill COVID-19 patients and their...

Y-90 SIRT: evaluation of TCP variation across dosimetric models.

EJNMMI physics

Van BJ, Dewaraja YK, Sangogo ML, Mikell JK.
PMID: 34114115

INTRODUCTION: Much progress has been made in implementing selective internal radiation therapy (SIRT) as a viable treatment option for hepatic malignancies. However, there is still much need for improved options for calculating the amount of activity to be administered....

DblurDoseNet: A deep residual learning network for voxel radionuclide dosimetry compensating for SPECT imaging resolution.

Medical physics

Li Z, Fessler JA, Mikell JK, Wilderman SJ, Dewaraja YK.
PMID: 34882821
Med Phys. 2021 Dec 09; doi: 10.1002/mp.15397. Epub 2021 Dec 09.

PURPOSE: Current methods for patient-specific voxel-level dosimetry in radionuclide therapy suffer from a trade-off between accuracy and computational efficiency. Monte Carlo (MC) radiation transport algorithms are considered the gold standard for voxel-level dosimetry but can be computationally expensive, whereas...

Spatial frequency analysis detects altered tissue organization following hamstring strain injury at time of injury but not return to sport.

BMC medical imaging
