Structural properties of complex plasmas in a homogeneous dc discharge.

Physical review letters

Mitic S, Klumov BA, Konopka U, Thoma MH, Morfill GE.
PMID: 18851380
Phys Rev Lett. 2008 Sep 19;101(12):125002. doi: 10.1103/PhysRevLett.101.125002. Epub 2008 Sep 16.

We report on the first three-dimensional (3D) complex plasma structure analysis for an experiment that was performed in an elongated discharge tube in the absence of striations. The low frequency discharge was established with 1 kHz alternating dc current...

Physiological Changes Within a Metalimnetic Layer of Oscillatoria rubescens.

Applied and environmental microbiology

Konopka A.
PMID: 16345643
Appl Environ Microbiol. 1980 Sep;40(3):681-4. doi: 10.1128/aem.40.3.681-684.1980.

Different depths within a metalimnetic layer of Oscillatoria rubescens were sampled, and changes in biochemical composition and photosynthetic rate were analyzed. Although differences in pigment and protein content were found, the photosynthetic rates of the samples were not significantly...

Influence of Temperature, Oxygen, and pH on a Metalimnetic Population of Oscillatoria rubescens.

Applied and environmental microbiology

Konopka A.
PMID: 16345803
Appl Environ Microbiol. 1981 Jul;42(1):102-8. doi: 10.1128/aem.42.1.102-108.1981.

Planktonic Oscillatoria spp. often inhabit depths of thermally stratified lakes in which gradients of physical and chemical factors occur. Measurements of photosynthetic rate or photosynthetic carbon metabolism were used to evaluate the importance of vertical gradients of temperature, oxygen,...

Detaching thiolates from copper and gold clusters: which bonds to break?.

Journal of the American Chemical Society

Konôpka M, Rousseau R, Stich I, Marx D.
PMID: 15382946
J Am Chem Soc. 2004 Sep 29;126(38):12103-11. doi: 10.1021/ja047946j.

The interaction of alkanethiolates with small coinage metal clusters of copper and gold was studied based on density functional theory with a focus on the metal-thiolate junction. Calculation of fragmentation energies indicate that for Cu(n)-thiolate (n = 1,3,5,7, and...

Optical, mechanical, and opto-mechanical switching of anchored dithioazobenzene bridges.

Chemphyschem : a European journal of chemical physics and physical chemistry

Turanský R, Konôpka M, Doltsinis NL, Stich I, Marx D.
PMID: 19856368
Chemphyschem. 2010 Feb 01;11(2):345-8. doi: 10.1002/cphc.200900690.

Cognitive genomics: Linking genes to behavior in the human brain.

Network neuroscience (Cambridge, Mass.)

Konopka G.
PMID: 29601049
Netw Neurosci. 2017 Feb 01;1(1):3-13. doi: 10.1162/netn_a_00003.

Correlations of genetic variation in DNA with functional brain activity have already provided a starting point for delving into human cognitive mechanisms. However, these analyses do not provide the specific genes driving the associations, which are complicated by intergenic...

Masquerading bundle branch block obscuring the diagnosis of Brugada syndrome: an electrocardiographic and vectorcardiographic study.

Clinical case reports

Konopka IV, Garro HA, Tepper RB, Pizzarelli N, Gonzalez MD, Acunzo RS.
PMID: 28781860
Clin Case Rep. 2017 Jul 11;5(8):1362-1368. doi: 10.1002/ccr3.1059. eCollection 2017 Aug.

We describe the induction of a masquerading bundle branch block in two patients with Brugada syndrome following the administration of Ajmaline. The development of this conduction disturbance prevented the correct electrocardiographic diagnosis. However, the simultaneously obtained vectocardiogram identified both...

Single-cell genomics reveals metabolic strategies for microbial growth and survival in an oligotrophic aquifer.

Microbiology (Reading, England)

Wilkins MJ, Kennedy DW, Castelle CJ, Field EK, Stepanauskas R, Fredrickson JK, Konopka AE.
PMID: 28206912
Microbiology (Reading). 2014 Feb;160(2):362-372. doi: 10.1099/mic.0.073965-0.

Bacteria from the genus Pedobacter are a major component of microbial assemblages at Hanford Site (a largely decommissioned nuclear production complex) in eastern Washington state, USA, and have been shown to change significantly in abundance in response to the...

Optimal management of scapholunate ligament injuries.

Orthopedic research and reviews

Konopka G, Chim H.
PMID: 30774459
Orthop Res Rev. 2018 Aug 06;10:41-54. doi: 10.2147/ORR.S129620. eCollection 2018.

Scapholunate ligament (SLL) injuries are a common cause of wrist pain and instability. Treatment of SLL injuries requires intricate understanding of wrist anatomy and biomechanics. Mindful physical exam and appropriate diagnostic studies can orient the surgeon to the defined...

Single position versus lateral-then-prone positioning for lateral interbody fusion and pedicle screw fixation.

Journal of spine surgery (Hong Kong)

Ziino C, Konopka JA, Ajiboye RM, Ledesma JB, Koltsov JCB, Cheng I.
PMID: 30714003
J Spine Surg. 2018 Dec;4(4):717-724. doi: 10.21037/jss.2018.12.03.

BACKGROUND: To compare perioperative and radiographic outcomes following lateral lumbar interbody fusions in two cohorts of patients who either underwent single position or dual position surgery.METHODS: Patients over the age of 18 with degenerative lumbar pathology who underwent a...
