New sesquiterpene lactones with antibacterial activity from Vernonia fastigiata.

Planta medica

Roos G, Prawat H, Walter CU, Klaiber I, Vogler B, Guse JH, Kraus W.
PMID: 17253310
Planta Med. 1998 Oct;64(7):673-4. doi: 10.1055/s-2006-957551.

Sesquiterpene lactones 1-5 were isolated for the first time from the ethyl acetate of Vernonia fastigiata (Asteraceae). Compounds 3, 4 and 5 are new, compounds 1 and 2 have been found earlier in other Vernonia species but not in...

Crystal structure and solution species of Ce(III) and Ce(IV) formates: from mononuclear to hexanuclear complexes.

Inorganic chemistry

Hennig C, Ikeda-Ohno A, Kraus W, Weiss S, Pattison P, Emerich H, Abdala PM, Scheinost AC.
PMID: 24090406
Inorg Chem. 2013 Oct 21;52(20):11734-43. doi: 10.1021/ic400999j. Epub 2013 Oct 03.

Cerium(III) and cerium(IV) both form formate complexes. However, their species in aqueous solution and the solid-state structures are surprisingly different. The species in aqueous solutions were investigated with Ce K-edge EXAFS spectroscopy. Ce(III) formate shows only mononuclear complexes, which...

A cross-sectional study of the association of age, race and ethnicity, and body mass index with sex steroid hormone marker profiles among men in the National Health and Nutrition Examination Survey (NHANES III).

BMJ open

Ritchey J, Karmaus W, Sabo-Attwood T, Steck SE, Zhang H.
PMID: 23043125
BMJ Open. 2012 Oct 06;2(5). doi: 10.1136/bmjopen-2012-001315. Print 2012.

OBJECTIVES: Since sex hormone markers are metabolically linked, examining sex steroid hormones singly may account for inconsistent findings by age, race/ethnicity and body mass index (BMI) across studies. First, these markers were statistically combined into profiles to account for...

A highly fluorescent pH sensing membrane for the alkaline pH range incorporating a BODIPY dye.

The Analyst

Hecht M, Kraus W, Rurack K.
PMID: 23091817
Analyst. 2013 Jan 07;138(1):325-32. doi: 10.1039/c2an35860c. Epub 2012 Oct 23.

A robust and re-usable dipstick-type fluorescent pH sensor for the alkaline pH range was developed by embedding a brightly fluorescent boron-dipyrromethene (BODIPY) dye bearing an acidic phenol moiety into a polyurethane matrix immobilized on a 3D epoxy-functionalized polymer support....

Maternal immune markers in serum during gestation and in breast milk and the risk of asthma-like symptoms at ages 6 and 12 months: a longitudinal study.

Allergy Asthma Clin Immunol. 2012 Jul 17;8(1):11. doi: 10.1186/1710-1492-8-11.

BACKGROUND: The role of breast milk on the risk of childhood asthma is in dispute. The aim of this prospective study is to determine the relationship of immune markers in maternal serum during gestation and breast milk to asthma-like...

This article proposes a Bayesian computing algorithm to infer Gaussian directed acyclic graphs (DAG's). It has the ability of escaping local modes and maintaining adequate computing speed compared to existing methods. Simulations demonstrated that the proposed algorithm has low...

Inhaled corticosteroids may prevent lung cancer in asthma patients.

Annals of thoracic medicine

Wang IJ, Liang WM, Wu TN, Karmaus WJJ, Hsu JC.
PMID: 30123334
Ann Thorac Med. 2018 Jul-Sep;13(3):156-162. doi: 10.4103/atm.ATM_367_17.

BACKGROUND: It is unclear whether inhaled corticosteroids (ICS) have chemopreventive effect on lung cancer (LC) development in humans. We investigated the association between the ICS use in asthma patients and the risk of LC.METHODS: We conducted a nationwide, population-based...
