We have developed two types of potential imaging agents using F-MRI: F-containing styrylbenzoxazole derivative (Shiga-X22) and curcumin derivative (Shiga-Y5). Shiga-Y5 detects both Aβ oligomers and Aβ aggregates, while Shiga-X22 only detects Aβ aggregates. Thus, the Shiga-Y5 images subtracted by Shiga-X22 may reflect…
Carbon based solar cell has attracted researcher attention as a replacement of silicon for use in solar cell material in the future. The amorphous carbon thin films doped with ptype iodine have been prepared by using a thermal CVD system. In this work, the effect of doping time for the electrical properties of nanostr…
Glutamate, as the major excitatory neurotransmitter in the central nervous system is involved in many aspects of normal brain function including learning, memory and behavior (Campos-Peña et al., 2014, Hynd et al., 2004). During Alzheimer’s disease (AD), the high levels of glutamate, induces excitotoxicity and leads t…

Several studies have shown the utility of the early phase uptake of Ab PET tracers to provide perfusion-like information. The goal of this study was to compare the perfusion-like distribution supplied by early phase of Ab PET tracers C-PiB (PiB) and F-Florbetaben (FBB), as well as the tau tracer F-AV1451 (AV1451), to…
The demand for implants with individual shape requires the development of new methods and approaches to their production. The obvious advantages of additive technologies and selective laser sintering are the capabilities to form both the external shape of the product and its internal structure. Recently appeared and a…
Alzheimer’s disease (AD) is a common neurodegenerative disorder characterized by a progressive decline in memory as a result of neuronal cell death. One of the pathological hallmarks of AD includes the accumulation of amyloid-beta (Aβ) toxic oligomers. Many developed small molecule drugs demonstrating neutralizing act…
Nella tesi si discute la suscettivita magnetica nella fase normale dei cuprati superconduttori ad alta Tc, utilizzando un formalismo di gauge basato sulla separazione dei gradi di liberta di carica e spin nelle eccitazioni a bassa energia, confrontando i dati sperimentali con i risultati dei calcoli teorici.
Alzheimer’s disease (AD) is a widespread progressive neurodegenerative disease but to date, no curative treatment is established. To target toxic amyloid-beta (Aβ) species and to convert them into non-toxic species, we have developed and designed D-enantiomeric peptides. Here, we investigated if intraperitoneal and in…
Multiple F amyloid PET imaging drugs have been approved for clinical use by the FDA. [C]PiB is an amyloid imaging drug used in many research centers. Understanding any variation in uptake patterns between different amyloid drugs is important in cross-amyloid-drug imaging analyses. We performed [F]Flutametamol and [C]P…
In this work, studies concerning determination of the oxide nanoparticles effect on structure and performance of the welds and plasma coatings were conducted. Ways ofintroducing nanodisperse refractory powders to the weld pool and how to cover with thedeactivation of nanoparticles powder were determined. Introducing o…
Human γ-secretase is an intra-membrane protease that cleaves many different substrates. Aberrant cleavage of Notch is implicated in cancer, while abnormalities in cutting amyloid precursor protein lead to Alzheimer's disease. We use cryo-EM structure determination to solve the atomic structure of human γ-secretase, an…
Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is an autosomal dominant hereditary disease, characterized by cerebral white matter degeneration with demyelination and axonal spheroids leading to progressive cognitive and motor dysfunction. HDLS is caused by mutations of the colony-stimulating factor 1 re…
Bu çalışmada karbon nano tüplerin (KNT) suda disperse olmasına sodyum dodesil sülfat (SDS) yüzey aktif maddesinin etkisi incelenmiştir. Karbon nano tüpler farklı derişimlerde ki sodyum dodesil sülfat çözeltilerine ultrasonikasyon işlemi ile disperse edilmiş ve bu çözeltilerin zeta potansiyelleri ölçülmüştür.
Central Vehicle Wash Facilities CVWFs at military installations are essential for supporting the readiness of tactical vehicles. Steel wash-rack pumps are vulnerable to accelerated degradation where supply water is corrosive and infused with fines. Pump failure can occur with little warning, taking the CVWF out of ser…
STEMCHEM is a COST action aiming to target causes of drug resistance in cancer stem cells. Cancer stem cells are cells which are believed to be responsible for the larger part of the regenerative capacity of cancers. They are also thought to be similar to adult stem cells in that they do not proliferate most of the ti…
Low-loss and high interference-suppression transmission lines (TLs) are presented in this paper by introducing field confinement in the Spoof Surface Plasmon Polartions (SPPs). By changing the dispersion behavior of SPP mode, the field confinement can be controlled. And the loose confinement of field leads to a lower-…
This paper shows a study of a new kind of circulator with spoof surface plasmon polaritons (SSPPs). In this letter, the combination of SSPPs and Y-junction in inner conductor is in consideration. SSPPs transmission mode and TEM mode is dominant in different band. That makes the broadband characteristic of the circulat…
A new compact planar diplexer at 2.75 and 3.45 GHz consisting of two connected bandpass filters using open-stub loaded composite right/left-handed (OSL-CRLH) resonators has been presented. For this miniaturized diplexer, the center frequencies and bandwidths of two passbands can be determined by the sizes of their CRL…
In this paper, we propose a multi-layered metamaterial that consists of three metallic layers and two dielectric spacer layers to realize efficient dual-band asymmetric transmission for linearly polarized wave. The simulated results show that the metamaterial can achieve broadband and high efficiency cross-polarizatio…
