Rhenium Complexes with Red-Light-Induced Anticancer Activity.

European journal of inorganic chemistry

Wähler K, Ludewig A, Szabo P, Harms K, Meggers E.
PMID: 25050081
Eur J Inorg Chem. 2014 Feb 01;2014(5):807-811. doi: 10.1002/ejic.201301474.

Rhenium(I) pyridocarbazole complexes with photoinduced antiproliferative activity are reported. The substitutionally inert complexes induce cell death by singlet oxygen generation upon irradiation with red light (

Natural Genetic Variation of Seed Micronutrients of Arabidopsis thaliana Grown in Zinc-Deficient and Zinc-Amended Soil.

Frontiers in plant science

Chen X, Yuan L, Ludewig U.
PMID: 27507976
Front Plant Sci. 2016 Jul 26;7:1070. doi: 10.3389/fpls.2016.01070. eCollection 2016.

The quality of edible seeds for human and animal nutrition is crucially dependent on high zinc (Zn) and iron (Fe) seed concentrations. The micronutrient bioavailability is strongly reduced by seed phytate that forms complexes with seed cations. Superior genotypes...

Bernal random loose packing through freeze-thaw cycling.

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

Ludewig F, Vandewalle N, Dorbolo S, Pakpour M, Lumay G.
PMID: 26274104
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Jul;92(1):010202. doi: 10.1103/PhysRevE.92.010202. Epub 2015 Jul 23.

We study the effect of freeze-thaw cycling on the packing fraction of equal spheres immersed in water. The water located between the grains experiences a dilatation during freezing and a contraction during melting. After several cycles, the packing fraction...

Cluster growth in driven granular gases.

Physical review. E

Noirhomme M, Ludewig F, Vandewalle N, Opsomer E.
PMID: 28297928
Phys Rev E. 2017 Feb;95(2):022905. doi: 10.1103/PhysRevE.95.022905. Epub 2017 Feb 23.

We investigate numerically and theoretically the internal structures of a driven granular gas in cuboidal cell geometries. Clustering is reported and particles are classified as gaseous or clustered via a local packing fraction criterion based on a Voronoi tessellation....

Insect Herbivory-Elicited GABA Accumulation in Plants is a Wound-Induced, Direct, Systemic, and Jasmonate-Independent Defense Response.

Frontiers in plant science

Scholz SS, Reichelt M, Mekonnen DW, Ludewig F, Mithöfer A.
PMID: 26734035
Front Plant Sci. 2015 Dec 22;6:1128. doi: 10.3389/fpls.2015.01128. eCollection 2015.

The non-proteinogenic amino acid γ-aminobutyric acid (GABA) is present in all organisms analyzed so far. In invertebrates GABA acts as a neurotransmitter; in plants different functions are under discussion. Among others, its involvement in abiotic stress reactions and as...

Surveilling the Potential for Precision Medicine-driven PD-1/PD-L1-targeted Therapy in HNSCC.

Journal of Cancer

Mann JE, Hoesli R, Michmerhuizen NL, Devenport SN, Ludwig ML, Vandenberg TR, Matovina C, Jawad N, Mierzwa M, Shuman AG, Spector ME, Brenner JC.
PMID: 28261333
J Cancer. 2017 Feb 09;8(3):332-344. doi: 10.7150/jca.17547. eCollection 2017.

Immunotherapy is becoming an accepted treatment modality for many patients with cancer and is now approved for use in platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). Despite these successes, a minority of patients with HNSCC...

Rate-equilibrium relationships in hydride transfer reactions: the role of intrinsic barriers.

Journal of the American Chemical Society

Würthwein EU, Lang G, Schappele LH, Mayr H.
PMID: 11942847
J Am Chem Soc. 2002 Apr 17;124(15):4084-92. doi: 10.1021/ja0121540.

A literature survey on the kinetics of hydride abstractions from CH-groups by carbocations reveals a general phenomenon: Variation of the hydride acceptor affects the rates of hydride transfer to a considerably greater extent than an equal change of the...

Impact of intracytoplasmic sperm injection on the activation and fertilization process of oocytes.

Reproductive biomedicine online

Ludwig M, Schröder AK, Diedrich K.
PMID: 12513861
Reprod Biomed Online. 2001;3(3):230-240. doi: 10.1016/s1472-6483(10)62042-1.

Intracytoplasmic sperm injection (ICSI) is used worldwide to treat preferentially severe cases of male factor infertility. In this review, data regarding the processes of oocyte activation and fertilization in non-assisted conception, conventional IVF and ICSI are discussed. The second...

A comparison of skinfolds and leg-to-leg bioelectrical impedance for the assessment of body composition in children.

Dynamic medicine : DM

Goss F, Robertson R, Williams A, Sward K, Abt K, Ladewig M, Timmer J, Dixon C.
PMID: 14498990
Dyn Med. 2003 Aug 26;2(1):5. doi: 10.1186/1476-5918-2-5.

BACKGROUND: This field-based investigation examined the congruence between skinfolds and bioelectrical impedance in assessing body composition in children. METHODS: Subjects were 162 female and 160 male children 10-15 years of age. Skinfold measures obtained at the triceps and medial...

Effect of friction in a toy model of granular compaction.

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

Ludewig F, Dorbolo S, Vandewalle N.
PMID: 15600600
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Nov;70(5):051304. doi: 10.1103/PhysRevE.70.051304. Epub 2004 Nov 10.

A toy model of granular compaction which includes some resistance due to granular arches is proposed. In this model, the solid/solid friction of contacting grains is a key parameter and a slipping threshold omega(c) is defined. Realistic compaction behaviors...
