TORC1 coordinates the conversion of Sic1 from a target to an inhibitor of cyclin-CDK-Cks1

2017

Eukaryotic cell cycle progression through G(1)-S is driven by hormonal and growth-related signals that are transmitted by the target of rapamycin complex 1 (TORC1) pathway. In yeast, inactivation of TORC1 restricts G(1)-S transition due to the rapid clearance of G(1) cyclins (Cln) and the stabilization of the B-type cyclin (Clb) cyclin-dependent kinase (CDK) inhibitor Sic1. The latter mechanism remains mysterious but requires the phosphorylation of Sic1-Thr(173) by Mpk1 and inactivation of the Sic1-pThr(173)-targeting phosphatase (PP2A(Cdc55)) through greatwall kinase-activated endosulfines. Here we show that the Sic1-pThr(173) residue serves as a specific docking site for the CDK phospho-a…

Diffusional Kurtosis Imaging in the Diffusion Imaging in Python Project

2021

ABSTRACTDiffusion-weighted magnetic resonance imaging (dMRI) measurements and models provide information about brain connectivity and are sensitive to the physical properties of tissue microstructure. Diffusional Kurtosis Imaging (DKI) quantifies the degree of non-Gaussian diffusion in biological tissue from dMRI. These estimates are of interest because they were shown to be more sensitive to microstructural alterations in health and diseases than measures based on the total anisotropy of diffusion which are highly confounded by tissue dispersion and fiber crossings. In this work, we implemented DKI in the Diffusion in Python (DIPY) project - a large collaborative open-source project which …

Physics, Techniques and Review of Neuroradiological Applications of Diffusion Kurtosis Imaging (DKI)

2016

In recent years many papers about diagnostic applications of diffusion tensor imaging (DTI) have been published. This is because DTI allows to evaluate in vivo and in a non-invasive way the process of diffusion of water molecules in biological tissues. However, the simplified description of the diffusion process assumed in DTI does not permit to completely map the complex underlying cellular components and structures, which hinder and restrict the diffusion of water molecules. These limitations can be partially overcome by means of diffusion kurtosis imaging (DKI). The aim of this paper is the description of the theory of DKI, a new topic of growing interest in radiology. DKI is a higher or…

2021

Postać Jana Karola Chodkiewicza (1686–1712) z linii supraskiej nie doczekała się do tej pory swojego opracowania choćby w postaci noty biograficznej. Artykuł niniejszy przybliża więc wybrany fragment z życiorysu wyżej wymienionego bohatera, który w latach 1700–1705 przebywał na naukach w szkole jezuickiej w Warszawie. Okres nauk stanowił ważne wydarzenie w życiu młodych magnatów, którzy w ich ramach przygotowywali się do służby państwowej i funkcjonowania w społeczeństwie szlacheckim. Nie inaczej było w przypadku Jana Karola, dziedzica ogromnej fortuny chodkiewiczowskiej, który resztę swojego krótkiego życia spędził później na sporach o dobra ojczyste. Młody starosta pobierał nauki w trudny…

Jan Karol Chodkiewicz (1686–1712) – szkic biograficzny młodego magnata

2021

Artykuł stanowi próbę zaprezentowania postaci Jana Karola Chodkiewicza z linii supraskiej (1686–1712), syna starosty błudeńskiego i oboźnego wielkiego litewskiego Jerzego Karola Chodkiewicza oraz Marianny Tekli z Naruszewiczów, który do tej pory nie doczekał się żadnego szerszego opracowania naukowego. Podstawę źródłową szkicu biograficznego Chodkiewicza stanowią materiały przechowywane w Archiwum Narodowym w Krakowie, w zespole Archiwum Młynowskie Chodkiewiczów. Różnorodność znajdujących się w nim dokumentów pozwoliła na możliwie jak najdokładniejsze odtworzenie jego życiorysu. Z niego wyłania się postać Jana Karola, który osierocony przez ojca w dzieciństwie zdany był na opiekę swojej mat…

SETIL: Italian multicentric epidemiological case–control study on risk factors for childhood leukaemia, non hodgkin lymphoma and neuroblastoma: study…

2014

Background Aetiology of childhood leukaemia and childhood neoplasm is poorly understood. Information on the prevalence of risk factors in the childhood population is limited. SETIL is a population based case–control study on childhood leukaemia, conducted with two companion studies on non-Hodgkin Lymphoma (NHL) and neuroblastoma. The study relies on questionnaire interviews and 50 Hz magnetic field (ELF-MF) indoor measurements. This paper discusses the SETIL study design and includes descriptive information. Methods The study was carried out in 14 Italian regions (78.3% of Italian population aged 0–10). It included leukaemia, NHL and neuroblastoma cases incident in 0–10 year olds in 1998–20…
