Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Influence of hydraulic resistance on flow features in an open channel confluence [PDF]

, 2014
A numerical model based on the 3D shallow water equations is set up for a 90° angle open channel confluence. The model is first calibrated and validated using experimental data by (Shumate, 1998).

Non-linear electronic transport and anomalous resistance fluctuations in the stripes state of $La_2NiO_{4.14}$

, 2007
We report on electronic transport measurements in $La_2NiO_{4.14}$. Non-Ohmic and hysteretic $V(I)$ curves are measured for $T \lesssim$ 220 $K$. Large and non Gaussian resistance fluctuations can be observed, with strong cooling rate dependence.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Collisional series resistance in electron beams

Electronics Letters, 1974
The standard reference books on electron optics, Glaser (1952), Sturrock (1955) and Grivet (1972), do not consider the possibility that an electron beam can exhibit a series resistance, even at zero frequency. The letter demonstrates that a series-resistance term must exist. Numerical estimates of the series resistance are given, from which it is shown

Compensation for resistance in series with excitable membranes

Biophysical Journal, 1984
Extracellular resistance in series (Rs) with excitable membranes can give rise to significant voltage errors that distort the current records in voltage-clamped membranes. Electrical methods for measurement of and compensation for such resistances are described and evaluated.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Resistance Breeding in Apple at Dresden-Pillnitz [PDF]

, 2008
Resistance breeding in apple has a long tradition at the Institute of Fruit Breeding now Julius Kuehn-institute in Dresden-Pillnitz. The breeding was aimed at the production of multiple resistance cultivars to allow a more sustainable and environmentally
