Kryptologia a prawo – wybrane zagadnienia: idea kryptowaluty i jej wpływu na ewolucję oszustw w internecie

2016

Rozwój cyberprzestrzeni i jej narzędzi kreuje nowe zagadnienia zarówno w świecie wirtualnym, jak i realnym. Pojawienie się nowego elementu, tzn. waluty cyfrowej w postaci monet kryptograficznych spowodowało szereg zmian w funkcjonowaniu użytkowników w Sieci. Wraz ze zmianami ewoluowały również metody stosowane przez cyberprzestępców. Celem artykułu jest ukazanie, jaki wpływ wywarły monety typu bitcoin na powstanie nowych form oszustw występujących w Internecie

The strong coupling constant: State of the art and the decade ahead

2022

This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling $\alpha_s$. The current status of the seven methods presently used to determine $\alpha_s$ based on: (i) lattice QCD, (ii) hadronic $\tau$ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. Novel $\alpha_s$ determinations are discussed, as well as the averaging method used to obtain the PDG world-average value at the reference Z boson mass scale, $\…

Epigenetic siRNA and Chemical Screens Identify SETD8 Inhibition as a Therapeutic Strategy for p53 Activation in High-Risk Neuroblastoma

2017

Given the paucity of druggable mutations in high-risk neuroblastoma (NB), we undertook chromatin-focused small interfering RNA and chemical screens to uncover epigenetic regulators critical for the differentiation block in high-risk NB. High-content Opera imaging identified 53 genes whose loss of expression led to a decrease in NB cell proliferation and 16 also induced differentiation. From these, the secondary chemical screen identified SETD8, the H4K20me1 methyltransferase, as a druggable NB target. Functional studies revealed that SETD8 ablation rescued the pro-apoptotic and cell-cycle arrest functions of p53 by decreasing p53K382me1, leading to activation of the p53 canonical pathway. I…

Cell-cycle control in cell-biomaterial interactions

2000

Current biocompatibility testing involves the demonstration of cell proliferation, which is usually interpreted as a sign of positive biocompatibility when the materials sustain cell proliferation. As the field of biomaterials research is rapidly moving toward tissue-engineered devices and hybrid organs, control of cell function has become a main topic. Cell function, which involves specific differentiation pathways, cannot be separated from cell-cycle control. The study of cell-cycle control is an important extension of routine proliferation assays and has extensive roots in developmental and tumor biology. We studied the expression of the tumour suppressor gene p53 and the proliferation-a…

Apollon gene silencing induces apoptosis in breast cancer cells via p53 stabilisation and caspase-3 activation

2009

We analysed the effects of small interfering RNA (siRNA)-mediated silencing of Apollon, a member of the inhibitors of apoptosis protein family, on the proliferative potential and ability of human breast cancer cell lines to undergo apoptosis. In wild-type p53 ZR75.1 cells, Apollon knockdown resulted in a marked, time-dependent decline of cell growth and an increased rate of apoptosis, which was associated with p53 stabilisation and activation of the mitochondrial-dependent apoptotic pathway. Pre-incubation of cells with a p53-specific siRNA resulted in a partial rescue of cell growth inhibition, as well as in a marked reduction of the apoptotic response, indicating p53 as a major player in …

Targeting HSP90 with the small molecule inhibitor AUY922 (luminespib) as a treatment strategy against hepatocellular carcinoma

2018

Hepatocellular carcinoma (HCC) is a highly malignant tumor that responds very poorly to existing therapies, most probably due to its extraordinary inter- and intra-tumor molecular heterogeneity. The modest therapeutic response to molecular targeted agents underlines the need for new therapeutic approaches for HCC. In our study, we took advantage of well-characterized human HCC cell lines, differing in transcriptomic subtypes, DNA mutation and amplification alterations, reflecting the heterogeneity of primary HCCs, to provide a preclinical evaluation of the specific heat shock protein 90 (HSP90) inhibitor AUY922 (luminespib). Indeed, HSP90 is highly expressed in different tumor types, but it…

Breslau. Nazwa miasta jako dziedzictwo kulturowe — zarys problematyki w perspektywie analizy dyskursu historycznego

2020

W artykule śledzę taktyki przywoływania (i unikania) wcześniejszych nazw współczesnego Wrocławia jako elementu tworzenia jego dziedzictwa kulturowego. Na przykładzie opracowań historycznych i wykorzystując metodę analizy dyskursu, pokazuję mechanizmy kreowania różnie akcentowanych przeszłości miasta. Opierając się na użyciu nazwy historycznej (na przykład Breslau) czy konsekwentnie tylko współczesnej (Wrocław), wskazuję, że za strategią wyboru nazwy stoją odmienne, ideologicznie uwarunkowane, narracje. Jedni badacze, używając wcześniejszych, historycznych nazw miasta, tworzą obraz ciągle zmieniającego się europejskiego ośrodka miejskiego, natomiast drudzy, posługując się wyłącznie współczes…
