Analysis of Nicotine and Its Oxidation Products in Nicotine Chewing Gum by a Molecularly Imprinted Solid-Phase Extraction
2000
Chromatographic stationary phases showing exceptional selectivity for nicotine can be prepared by the technique of molecular imprinting. Such phases were used in the search for a rapid cleanup step for nicotine and some of its oxidation products in chewing gum formulations. Thus, using an organic mobile phase, the nicotine analytes from chewing gums dissolved in nonpolar solvent were retained, whereas the nonpolar matrix eluted close to the void peak. A subsequent switch to an acidic mobile phase resulted in elution of the analytes as one sharp peak. Due to weak binding of the less basic oxidation products, other imprinted polymers were tested, and the solid-phase extraction procedure was o…
Sur le fonctionnement du Journal de Mathématiques Pures et Appliquées entre 1917 et 1937 d'après des lettres inédites de Henri Villat à Robert de Mon…
2011
We are interested in the Journal of Mathématiques Pures and Appliquées (JMPA) over the period 1917-1937. From the end of 1921 , two mathematicians worked to its publication, Henri Villat as editor in chief and Robert Montessus Ballore as associate editor. Through unpublished letters , we descrive the operation of the JMPA after WWI.
Were the chaotic ELMs in TCV the result of an ARMA process?
2004
The results of a previous paper claiming the demonstration that edge localized mode (ELM) dynamics on TCV are chaotic in a number of cases has recently been called into question, because the statistical test employed was found to also identify linear auto regressive—moving average (ARMA) models as chaotic. The TCV ELM data has therefore been re-examined with an improved method that is able to make this distinction, and the ARMA model is found to be an inappropriate description of the dynamics on TCV. The hypothesis that ELM dynamics are chaotic on TCV in a number of cases is therefore still favoured.
On the strength of the U A (1) anomaly at the chiral phase transition in N f = 2 QCD
2016
We study the thermal transition of QCD with two degenerate light flavours by lattice simulations using $O(a)$-improved Wilson quarks. Temperature scans are performed at a fixed value of $N_t = (aT)^{-1}=16$, where $a$ is the lattice spacing and $T$ the temperature, at three fixed zero-temperature pion masses between 200 MeV and 540 MeV. In this range we find that the transition is consistent with a broad crossover. As a probe of the restoration of chiral symmetry, we study the static screening spectrum. We observe a degeneracy between the transverse isovector vector and axial-vector channels starting from the transition temperature. Particularly striking is the strong reduction of the split…

Assessing the impact of CMF/FEC/FEC-DOC/ETC (dose-dense) adjuvant chemotherapy in dependency of positive axillary lymph nodes on survival: A retrospe…
2013
1074 Background: Adjuvant chemotherapy has changed dramatically in the last decades. Anthracycline-/taxane-based and dose-dense chemotherapy regimens improved survival in node positive breast cancer. This study tries to answer the following questions: (1) Are there differences in survival dependent on chemotherapy regimens in 0/0-3/4-10/<10 positive lymph nodes? (2) Is it possible to define a cut-off of positive lymph nodes for the use of Taxane-based and dose dense chemotherapy? Methods: This German is a multi-center [17 participating hospitals all are certified as breast cancer centers] retrospective cohort study. We included CMF (1.385), FEC (1.170), FEC-DOC (1.723), and dose-dense E…

Treatment of embryonal tumors with multilayered rosettes with carboplatin/etoposide induction and high-dose chemotherapy within the prospective P-HIT…
2021
Abstract Background Embryonal tumors with multilayered rosettes (ETMR) are highly aggressive tumors occurring in early childhood. Published clinical data refer to retrospective, heterogeneously treated cohorts. Here, we describe the outcome of patients treated according to the prospective P-HIT trial and subsequent HIT2000-interim-registry. Patients and methods Age-stratified treatment included carboplatin/etoposide induction, tandem high-dose chemotherapy (“CARBO/ETO + HDCT”), and response-stratified radiotherapy. Patients with centrally reviewed neuropathological and molecularly confirmed diagnosis of ETMR recruited within the P-HIT trial (2001-2011; n = 19), the HIT2000-interim-registry …
