We have analyzed the character of B═B and B≡B bonds in the neutral molecules of general form: LHB═BHL (2-L) and LB≡BL (3-L), for various ancillary ligands L attached to the boron center, based on a recently developed method that...

The factors shaping cometary nuclei are still largely unknown, but could be the result of concurrent effects of evolutionary and primordial processes. The peculiar bilobed shape of comet 67P/Churyumov-Gerasimenko may be the result of the fusion of two objects...

Cardiovascular disease and type 2 diabetes in evolutionary perspective: a critical role for helminths?.

Evolution, medicine, and public health

Gurven MD, Trumble BC, Stieglitz J, Blackwell AD, Michalik DE, Finch CE, Kaplan HS.
PMID: 27666719
Evol Med Public Health. 2016 Jan;2016(1):338-357. doi: 10.1093/emph/eow028. Epub 2016 Sep 25.

Heart disease and type 2 diabetes are commonly believed to be rare among contemporary subsistence-level human populations, and by extension prehistoric populations. Although some caveats remain, evidence shows these diseases to be unusual among well-studied hunter-gatherers and other subsistence...

Transarterial chemoembolization (TACE) with degradable starch microspheres (DSM) in hepatocellular carcinoma (HCC): multi-center results on safety and efficacy.

Oncotarget. 2017 Aug 07;8(42):72613-72620. doi: 10.18632/oncotarget.19997. eCollection 2017 Sep 22.

BACKGROUND: Hepatocellular carcinoma (HCC) is the 3rd leading cause of cancer-related death worldwide. The majority of HCCs are diagnosed in a stage that is not eligible for curative resection. For intermediate stage HCC, transarterial chemoembolization (TACE) is the recommended...

Gas Evolution in Operating Lithium-Ion Batteries Studied In Situ by Neutron Imaging.

Scientific reports

Michalak B, Sommer H, Mannes D, Kaestner A, Brezesinski T, Janek J.
PMID: 26496823
Sci Rep. 2015 Oct 26;5:15627. doi: 10.1038/srep15627.

Gas generation as a result of electrolyte decomposition is one of the major issues of high-performance rechargeable batteries. Here, we report the direct observation of gassing in operating lithium-ion batteries using neutron imaging. This technique can be used to...

Genome Med. 2015 Mar 14;7(1):26. doi: 10.1186/s13073-015-0149-z. eCollection 2015.

BACKGROUND: Heart failure (HF) is the most common cause of morbidity and mortality in developed countries. Here, we identify biologically relevant transcripts that are significantly altered in the early phase of myocardial infarction and are associated with the development...

Deuteron quadrupole coupling constants and reorientational correlation times in protic ionic liquids.

Physical chemistry chemical physics : PCCP

Strauch M, Bonsa AM, Golub B, Overbeck V, Michalik D, Paschek D, Ludwig R.

Phys Chem Chem Phys. 2016 Jul 21;18(27):17788-94. doi: 10.1039/c6cp01462c. Epub 2016 Apr 12.

We describe a method for the accurate determination of deuteron quadrupole coupling constants χD for N-D bonds in triethylammonium-based protic ionic liquids (PILs). This approach was first introduced by Wendt and Farrar for O-D bonds in molecular liquids, and...

Effects of spatial inhomogeneities on the dynamics of cavity solitons in quadratically nonlinear media.

We study the dynamics of cavity solitons under the influence of spatial inhomogeneities and derive generalized equations of motions. For perturbations large compared to the soliton size we find the modulus of the soliton velocity to be proportional to...
