Simulation of guiding of multiply charged projectiles through insulating capillaries

open access: yes, 2005
Recent experiments have demonstrated that highly charged ions can be guided through insulating nanocapillaries along the direction of the capillary axis for a surprisingly wide range of injection angles.

Classical non-homologous end-joining pathway utilizes nascent RNA for error-free double-strand break repair of transcribed genes

open access: yesNature Communications, 2016
DNA double-strand breaks (DSBs) leading to loss of nucleotides in the transcribed region can be lethal. Classical non-homologous end-joining (C-NHEJ) is the dominant pathway for DSB repair (DSBR) in adult mammalian cells.

Classics in Neuroimaging: Imaging the Dopaminergic Pathway with PET [PDF]

open access: yesACS Chemical Neuroscience, 2017
The success of positron emission tomography (PET) for observing molecular processes underlying brain function and disease is underpinned by radiotracer chemistry. From the earliest applications of PET to measure dopamine synthesis capacity and the abundance of neuroreceptors and transporters, to the more recent topic of dynamic neurochemical imaging ...

Targeted metabolomics reveals novel diagnostic biomarkers for colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study employed targeted metabolomic profiling to identify 302 distinct metabolites present in platelet‐rich plasma (PRP), revealing aberrant metabolic profiles amongst individuals diagnosed with colorectal cancer (CRC). Compared to carcinoembryonic antigen (CEA) and cancer antigen 19‐9 (CA199), our metabolite panel showed improved sensitivity ...

Fingerprints of slingshot non-sequential double ionization on two-electron probability distributions [PDF]

open access: yes, 2019
We study double ionization of He driven by a near-single-cycle laser pulse at low intensities at 400 nm. Using a three-dimensional semiclassical model, we identify the pathways that prevail non-sequential double ionization (NSDI).

Overt and covert paths for sound in the auditory system of mammals. 2 [PDF]

open access: yesarXiv, 2022
Current scientific consensus holds that sound is transmitted, solely mechanically, from the tympanum to the cochlea via ossicles. However this theory does not explain the hearing extreme quality regarding high frequencies in mammals. So, we propose a bioelectronic pathway (the covert path) that is complementary to the overt path.

MET variants with activating N‐lobe mutations identified in hereditary papillary renal cell carcinomas still require ligand stimulation

open access: yesMolecular Oncology, EarlyView.
MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

Use of C4d as a diagnostic tool to classify membranoproliferative glomerulonephritis

open access: yesNefrología, 2017
Background: Membranoproliferative glomerulonephritis (MPGN type I, II and III) was reclassified in 2013 as MPGN and C3 glomerulopathy (C3G) based on the complement system activation mechanism.

Adverse prognosis gene expression patterns in metastatic castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
We aggregated a cohort of 1012 mCRPC tissue samples from 769 patients and investigated the association of gene expression‐based pathways with clinical outcomes. Loss of AR signaling, high proliferation, and a glycolytic phenotype were independently prognostic for poor outcomes, and an adverse transcriptional feature score incorporating these pathways ...

Serum concentrations of complement C3 and C4 in dogs with idiopathic epilepsy

open access: yesJournal of Veterinary Internal Medicine
Background High concentrations of complement factors are presented in serum of animal epilepsy models and human patients with epilepsy. Objectives To determine whether complement dysregulation occurs in dogs with idiopathic epilepsy (IE).
