High incidence of microsatellite instability and loss of heterozygosity in three loci in breast cancer patients receiving chemotherapy: a prospective study

BMC Cancer, 2012
Background The aim of the study was to evaluate potential chemotherapy-induced microsatellite instability, loss of heterozygosity, loss of expression in mismatch repair proteins and associations with clinical findings in breast cancer patients ...

Demonstration of long-reach PON using 10 Gb/s 3R burst-mode wavelength converter [PDF]

, 2013
Long-reach optical access networks promise significant cost savings. To merge existing metro and access networks to a single long-reach network, the long-reach technology has to address not only the power loss and fiber dispersion problems but also ...

Loss of DNA mismatch repair proteins in prostate cancer

Medicine, 2020
Abstract Recent studies have suggested an increased risk of prostate cancer in men with Lynch syndrome driven by germline mutations in mismatch repair (MMR) genes. However, the incidence and clinical implication of MMR deficiency in sporadic prostate cancers remain poorly understood.

Power generation characteristics of vertical bifacial photovoltaic arrays in heavy snow regions

EPJ Photovoltaics
Conventional tilted photovoltaic systems often experience reduced electricity generation and potential damage due to snow accumulation. In contrast, vertical bifacial photovoltaic systems demonstrate greater resilience against snow-related damage, making

Power enhanced solar PV array configuration based on calcudoku puzzle pattern for partial shaded PV system

Heliyon, 2023
The power output of solar photovoltaic systems can be affected by environmental factors, such as partial shading. This can lead to a decrease in the power conversion rate of the system.

Tunable n-path notch filters for blocker suppression: modeling and verification [PDF]

, 2013
N-path switched-RC circuits can realize filters with very high linearity and compression point while they are tunable by a clock frequency. In this paper, both differential and single-ended N-path notch filters are modeled and analyzed.

Stabilization of solitons in PT models with supersymmetry by periodic management

, 2011
We introduce a system based on dual-core nonlinear waveguides with the balanced gain and loss acting separately in the cores. The system features a "supersymmetry" when the gain and loss are equal to the inter-core coupling.

Endonuclease activities of MutLα and its homologs in DNA mismatch repair. [PDF]

, 2016
MutLα is a key component of the DNA mismatch repair system in eukaryotes. The DNA mismatch repair system has several genetic stabilization functions. Of these functions, DNA mismatch repair is the major one.
