Quantitative phase macroscopic system for label-free imaging of tissue sections
(İstanbul University, 2021)Optical microscopes are typically designed as versatile tools that are capable of imaging at various modalities with different resolutions in respective visual fields. A large extend of versatility causes increased complexity, ... -
Radiation type- and dose-specific transcriptional responses across healthy and diseased mammalian tissues
(MDPI, 2022)Ionizing radiation (IR) is a genuine genotoxic agent and a major modality in cancer treatment. IR disrupts DNA sequences and exerts mutagenic and/or cytotoxic properties that not only alter critical cellular functions but ... -
A rare ventriculoarterial connection: Double outlet of both ventricles
(Cambridge University Press, 2023)Ventriculoarterial connection is one of the important points of the segmental approach to congenital cardiac malformations. Double outlet of both ventricles is a rare form where both great arterial roots override the ... -
Real-time holographic tracking and control of microrobots
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)Digital holography is used to track the three-dimensional position of a magnetic microrobot maneuvered in real time by means of an electromagnetic manipulation system. The method presented is able to process holograms at ... -
Residues in the fructose-binding pocket are required for ketohexokinase-A activity
(2024)Excessive fructose consumption is a primary contributor to the global surges in obesity, cancer, and metabolic syndrome. Fructolysis is not robustly regulated and is initiated by ketohexokinase (KHK). In this study, we ... -
The role of positive and negative pressure on cavitation nucleation in nanodroplet-mediated histotripsy
(Iop Publishing Ltd, 2016)Nanodroplet-mediated histotripsy (NMH) is an ultrasound ablation technique combining histotripsy with acoustically sensitive perfluorocarbon (PFC) nanodroplets that can be selectively delivered to tumor cells for targeted ... -
S-layer fusion protein as a tool functionalizing emulsomes and CurcuEmulsomes for antibody binding and targeting
(Elsevier, 2015)Selective targeting of tumor cells by nanoparticle-based drug delivery systems is highly desirable because it maximizes the drug concentration at the desired target while simultaneously protecting the surrounding healthy ... -
Scattering metal waveguide based speckle-enhanced prism spectrometry
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)We present an optical efficiency improved speckle spectrometer where a scattering metal wave-guide is utilized along with a conventional prism spectrometer. We conducted extensive tests on 25 different scatterers, involving ... -
Selective binding of pVTK peptide-and bisphosphonate-functionalized micelles to prostate cancer cells, osteoblasts, and osteoclasts
(Andover House, Inc., 2022)This report describes the development of functionalized polymeric micelles encapsulating a chemotherapeutic agent. The results indicate the ability to achieve selective uptake into different cell populations in metastatic ... -
SELEX against whole-cell bacteria resulted in lipopolysaccharide binding aptamers
(Elsevier B.V., 2022)Nucleic acid aptamers are target-specific oligonucleotides selected from combinatorial libraries through an iterative in vitro screening process known as Systemic Evolution of Ligands by Exponential Enrichment (SELEX). In ... -
A simple yet time-optimal and linear-space algorithm for shortest unique substring queries
(Elsevier, 2015)We revisit the problem of finding shortest unique substring (SUS) proposed recently by Pei et al. (2013) [12]. We propose an optimal O(n) time and space algorithm that can find an SUS for every location of a string of size ... -
Soft segment length controls morphology of poly(ethylene oxide) based segmented poly(urethane-urea) copolymers in a binary solvent
(Elsevier Science Bv., 2017)It is known that morphology and structure-property behavior of poly(ethylene oxide) (PEO) based poly (urethane-urea) copolymers are affected by soft segment (SS) chain length. Here, a multi-scale computational study is ... -
A speckle-enhanced prism spectrometer with high dynamic range
(IEEE Inst Electrical Electronics Engineers Inc, 2018)We present a novel spectrometer device offering a wide wavelength range and high resolution. The device builds upon a conventional prism spectrometer; however, an additional scattering medium is introduced to generate a ... -
Surgical and transcatheter pulmonary valve replacement in patients with repaired tetralogy of Fallot: Cardiac magnetic resonance imaging characteristics and morphology of right ventricular outflow tract
(Springer, 2023)BackgroundPulmonary valve replacement is recommended in patients with repaired tetralogy of Fallot based on cardiac magnetic resonance imaging (MRI) criteria. This procedure is performed by surgical or transcatheter ... -
Synergistic inhibition of aggressive breast cancer cell migration and invasion by cytoplasmic delivery of anti-RhoC silencing RNA and presentation of EPPT1 peptide on "smart" particles
(Elsevier Science Bv, 2018)Overexpression of RhoC protein in breast cancer patients has been linked to increased cancer cell invasion, migration, and metastases. Suppressing RhoC expression in aggressive breast cancer cells using silencing RNA (siRNA) ... -
Temperature and pH-dependent behaviors of mAb drugs: A case study for trastuzumab
(MDPI, 2022)The distortions in the high-order structure of therapeutic monoclonal antibodies (mAbs) under different environmental conditions acutely affect mAb stability, resulting in altered safety, efficacy, and shelf-life profiles. ... -
