Identification of a differentially expressed thymidine kinase gene related to tapping panel dryness syndrome in the rubber tree (Hevea brasiliensis Muell. Arg.) by random amplified polymorphic DNA screening

open access: yesInternational Journal of Plant Biology, 2010
Tapping panel dryness (TPD) syndrome is one of the latex yield affecting factors in the rubber tree (Hevea brasiliensis Mull. Arg.). Therefore, identification of a DNA marker will be highly useful for screening progenies in breeding programs.

Optimal Asymmetric Quantum Cloning [PDF]

open access: yes, 2012
While the no-cloning theorem, which forbids the perfect copying of quantum states, is well-known as one of the defining features of quantum mechanics, the question of how well the theory allows a state to be cloned is yet to be completely solved. In this

Economical quantum cloning in any dimension

open access: yes, 2004
The possibility of cloning a d-dimensional quantum system without an ancilla is explored, extending on the economical phase-covariant cloning machine found in [Phys. Rev. A {\bf 60}, 2764 (1999)] for qubits.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Usefulness of classical communication for local cloning of entangled states

open access: yes, 2006
We solve the problem of the optimal cloning of pure entangled two-qubit states with a fixed degree of entanglement using local operations and classical communication.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Analysis of DNA methylation during the germination of wheat seeds

open access: yesBiologia Plantarum, 2012
DNA methylation is known to play a crucial role in regulating plant development and organ or tissue differentiation. Here, we focused on the DNA methylation dynamics during the germination of wheat seeds using the adapted AFLP technique so called ...

Multipartite Asymmetric Quantum Cloning

open access: yes, 2004
We investigate the optimal distribution of quantum information over multipartite systems in asymmetric settings. We introduce cloning transformations that take $N$ identical replicas of a pure state in any dimension as input, and yield a collection of ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.
