Ibrahim TF, Hafez A, Andrade-Barazarte H, Raj R, Niemela M, Lehto H, Numminen J, Jarvelainen J, Hernesniemi J.
PMID: 26664872
Surg Neurol Int. 2015 Oct 23;6:S560-5. doi: 10.4103/2152-7806.168074. eCollection 2015.

BACKGROUND: De novo intracranial aneurysms are reported to occur with varying incidence after intracranial aneurysm treatment. They are purported to be observed, however, with increased incidence after Hunterian ligation; particularly in cases of carotid artery occlusion for giant or...

Fluctuations of temperature gradients in turbulent thermal convection.

Physical review. E, Statistical, nonlinear, and soft matter physics

Sreenivasan KR, Bershadskii A, Niemela JJ.
PMID: 15903485
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Mar;71(3):035302. doi: 10.1103/PhysRevE.71.035302. Epub 2005 Mar 15.

Broad theoretical arguments are proposed to show, formally, that the magnitude G of the temperature gradients in turbulent thermal convection at high Rayleigh numbers obeys the same advection-diffusion equation that governs the temperature fluctuation T , except that the...

Thermoelectric and Structural Characterization of Al-Doped ZnO/Y₂O₃ Multilayers.

Journal of nanoscience and nanotechnology

Mele P, Saini S, Tiwari A, Hopkins PE, Miyazaki K, Ichinose A, Niemelä J, Karppinen M.
PMID: 29693985
J Nanosci Nanotechnol. 2017 Mar;17(3):1616-621. doi: 10.1166/jnn.2017.13717.

The influence of Y2O3 nanolayers on thermoelectric performance and structure of 2% Al-doped ZnO (AZO) thin films has been studied. Multilayers based on five 50 nm thick AZO layers alternated with few nanometers thick Y2O3 layers were prepared by...

Gene flow from domesticated escapes alters the life history of wild Atlantic salmon.

Nature ecology & evolution

Bolstad GH, Hindar K, Robertsen G, Jonsson B, Sægrov H, Diserud OH, Fiske P, Jensen AJ, Urdal K, Næsje TF, Barlaup BT, Florø-Larsen B, Lo H, Niemelä E, Karlsson S.

Nat Ecol Evol. 2017 Apr 10;1(5):124. doi: 10.1038/s41559-017-0124.

Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population dynamics and viability. Here, we show that individuals with...

24 mJ Cr.

The Review of scientific instruments

Stoychev LI, Cabrera H, Gadedjisso-Tossou KS, Vasiliev N, Zaporozhchenko Y, Nikolov IP, Sigalotti P, Demidovich AA, Suárez-Vargas JJ, Mocchiutti E, Pizzolotto C, Niemela J, Baruzzo M, Danailov MB, Vacchi A.
PMID: 31575267
Rev Sci Instrum. 2019 Sep;90(9):093002. doi: 10.1063/1.5115105.

We present the design of a Cr:forsterite based single-frequency master-oscillator power-amplifier laser system delivering much higher output energy compared to previous literature reports. The system has four amplifying stages with two-pass configuration each, thus enabling the generation of 24...

Cushing syndrome and glucocorticoids: T-cell lymphopenia, apoptosis, and rescue by IL-21.

The Journal of allergy and clinical immunology

Hwang S, Tatsi C, Kuehn HS, Niemela JE, Stoddard J, Su Y, Lodish M, Uzel G, Spolski R, Leonard WJ, Holland SM, Fleisher TA, Stratakis CA, Rosenzweig SD.
PMID: 34089750

BACKGROUND: Pediatric endogenous Cushing syndrome (eCs) is mainly caused by pituitary corticotropin-producing adenomas, and most glucocorticoid-dependent effects progressively regress upon tumor removal. eCs reproduces long-term, high-dose glucocorticoid therapy, representing a clean, natural, and unbiased model in which to study...

Customer perceptions of COVID-19 countermeasures on passenger ships during the pandemic.

Transportation research interdisciplinary perspectives

The COVID-19 pandemic devastated substantial portions of the tourism industry; the cruise industry particularly suffered from negative publicity as the virus spread rapidly on cruise ships. The pandemic is a disaster that the industry has been forced to adapt...

CARD9 Expression Pattern, Gene Dosage, and Immunodeficiency Phenotype Revisited.

BACKGROUND: CARD9 deficiency is an autosomal recessive primary immunodeficiency underlying increased susceptibility to fungal infection primarily presenting as invasive CNS Candida and/or cutaneous/invasive dermatophyte infections. More recently, a rare heterozygous dominant negative CARD9 variant c.1434 + 1G > C...
