On the perfomance of a photosystem II reaction centre-based photocell [PDF]

arXiv, 2016
The photosystem II reaction centre is the photosynthetic complex responsible for oxygen production on Earth. Its water splitting function is particularly favoured by the formation of a stable charge separated state via a pathway that starts at an accessory chlorophyll.

Isomonodromy sets of accessory parameters for Heun class equations [PDF]

arXiv, 2021
In this paper, we consider the monodromy and, in particularly, the isomonodromy sets of accessory parameters for the Heun class equations. We show that the Heun class equations can be obtained as limits of the linear systems associated with the Painlev\'{e} equations when the Painlev\'e transcendents go to one of the actual singular points of the ...

Supporting the identification of novel fragment-based positive allosteric modulators using a supervised molecular dynamics approach: A retrospective analysis considering the human A2A adenosine receptor as a key example [PDF]

, 2017
Structure-driven fragment-based (SDFB) approaches have provided efficient methods for the identification of novel drug candidates. This strategy has been largely applied in discovering several pharmacological ligand classes, including enzyme inhibitors ...

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

Molecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Determination of accessory parameters in a system of the Okubo normal form [PDF]

arXiv, 2020
A system of differential equations of the Okubo normal form containing accessory parameters is considered. A condition for determining special values of the accessory parameters is given. It is shown that the special values give the differential equation satisfied by a product of the Gauss hypergeometric functions.

Catheter Ablation of Tachyarrhythmias in Small Children [PDF]

, 2005
An estimated 80,000-100,000 radiofrequency ablation (RFA) procedures are performed in the United States each year.1 Approximately 1% of these are performed on pediatric patients at centers that contribute data to the Pediatric Radiofrequency Registry.2 ...

A recurrent concealed parahisian accessory pathway [PDF]

Clinical Case Reports, 2018
Key Clinical MessageThis case demonstrates the interest of ablating in the aortic root in case of resistant parahisian accessory pathways with failure of the right side approach. Failure on the right side may be due to fear of creating an AV block of failure to ablate critical fibers in the parahisian position.

Stroma gene signature predicts responsiveness to chemotherapy in pancreatic ductal adenocarcinoma patient‐derived xenograft models

Molecular Oncology, Volume 19, Issue 4, Page 1075-1091, April 2025.
Pancreatic ductal adenocarcinoma patient‐derived xenografts (PDAC‐PDXs) engrafted orthotopically in the pancreas of immunodeficient mice retain the main genetic and histopathological characteristics of the original human tumors. A 294 stroma gene signature differentiates between PDAC‐PDXs that are responsive to gemcitabine plus nab‐paclitaxel versus ...

Radiofrequency Ablation of Accessory Pathways in Chil- dren with Complex Congenital Cardiac Lesions: A Report of Three Cases

Journal of Tehran University Heart Center, 2015
Catheter ablation is an accepted, highly effective modality of treatment for cardiac arrhythmias in children. The success rate depends on the operator’s experience, especially in cases involving complex anatomies.

Antegrade and Retrograde Decremental Conduction Properties of an Accessory Pathway Associated with the Coronary Sinus Musculature

Indian Pacing and Electrophysiology Journal, 2015
A 32-year-old man underwent catheter ablation of an orthodromic atrioventricular reentrant tachycardia. The sinus rhythm electrocardiogram exhibited a normal PQ interval and no delta waves, but atrial pacing produced a prolonged PQ interval and wide QRS ...
