CEACAM1 participation in breast cancer progression

open access: yesMolecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Wavelength dependence of femtosecond laser ablation threshold of corneal stroma

open access: yesOptics Express, 2008
We measure the surface ablation threshold fluence of porcine corneal stroma for 100 fs laser pulses, with wavelengths between 800 nm and 1450 nm, generated by a Ti:sapphire-pumped optical parametric amplifier. The ablation threshold was found to vary only slightly within this wavelength range, between 1.5 and 2.2 J/cm(2).

Threshold signatures from VOLE

open access: yes, 2023
reservedThe focus of this thesis is on threshold digital signatures and in particular on Schnorr signatures (1991). Following the expiration of its patent in 2008, Schnorr signature has gained significance in the realm of digital signatures due to its ...

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

open access: yesMolecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Ablation Threshold of Sapphire by Pulsed Green Laser in Nanosecond Regime

open access: yes, 2011
To establish the green laser ablation process more accurately, a detailed knowledge of the exact value of ablation threshold is of great importance. Therefore, the presented paper has investigated the single pulse ablation threshold using four different ...

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

open access: yesMolecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Effect of ArF excimer laser irradiation on allyldiglycol carbonate (CR-39) polymer [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2015
In this paper, the effect of ArF excimer laser (193 nm) irradiation on CR-39 polymers was investigated. The polymers were divided into three sets. The first set of polymers was irradiated with ArF laser below the ablation threshold fluence and the second

Permanent His bundle pacing and atrioventricular node ablation in a case with drug-refractory atrial fibrillation

open access: yesTürk Kardiyoloji Derneği Arşivi, 2019
Permanent His bundle pacing (HBP) activates the ventricles through the normal conduction system and has become a useful technique for patients with a high ventricular pacing rate.

Peri‐left bundle branch pacing after atrioventricular node ablation and failed his bundle pacing in atrial fibrillation

open access: yesJournal of Arrhythmia, 2020
We described a case where peri‐left bundle branch pacing (PLBP) may become an alternative approach in difficult His bundle pacing (HBP) following atrioventricular nodal ablation in a patient with atrial fibrillation. After atrioventricular nodal ablation,
