Variability of ecdysteroid-induced cell cycle alterations in Drosophila Kc sublines.

1987

. The cell cycle of two lines isolated from Drosophila Kc cells was followed by flow cytofluorometry and cell counting. The first line is the 8-9K clone which grew in a medium supplemented with 5% serum; the second, named subline Kc0, grew in a serum-free medium. The stationary phase is characterized by a G2 cell accumulation: 73% in the 8-9K clone and 50% in the Kc0 subline. When the medium was supplemented with the steroid moulting hormone 20-hydroxyecdysone, more than 90% of 8-9K cells and 65% of Kc0 cells were progressively arrested in G2. In the continuous presence of 20-hydroxyecdysone, most of the 8-9K cells remain G2-arrested; no massive G2 release into M was observed and only a few…

Women and Pythagorean Philosophy. Review of D.M. Dutsch, Pythagorean Women Philosophers. Between Belief and Suspicion. Oxford: Oxford University Pres…

2021

In the last few decades, Pythagorean women and their intellectual status have aroused the interest of several scholars (C. Montepaone, S. Pomeroy and others). Against this background, the present book is a most welcome instrument for scholars interested in Pythagoreanism and in women in antiquity, for it deals with Pythagorean women philosophers between ‘critique and compliance’, that is, as the subtitle says, with both belief and suspicion, the two foundations of hermeneutics highlighted by P. Ricœur. Such a critical positioning induces D. to analyse anecdotes and pseudepigrapha in search for a possible identity of Pythagorean women philosophers at the margins of official discourses and te…

Eliptiskās līknes bāzēta kriptogrāfiska ietvara izstrāde

2016

Projekta mērķis ir piedāvāt izstrādātājiem personalizētu kriptogrāfisku sistēmu klienta-servera arhitektūras risinājumiem. Ietvars realizēts izmantojot Latvijā relatīvi jaunu un mazpazīstamu tehnoloģiju, kas fundamentāli balstīta uz eliptisko līkņu pār galīgiem pirmskaitļu laukiem matemātiskajām īpašībām. Projekta ietvaros tiek izveidots personalizēts informācijas šifrēšanas ietvars un lietotne, kas nodrošina ietvara funkcionalitātes demonstrāciju.

Gender and the gynecological examination: women's identities in doctors' narratives.

2007

The authors explore the constructions of gender in male doctors' narratives of gynecological examinations. Focusing on the ways in which gender identities are constructed in the stories of the medical encounter, they argue, first, that gender is more flexible during the visit with a gynecologist than has been suggested. Gendered identities are assumed and put aside as the interaction progresses, with its final stage—the pelvic examination—being constructed with gender removed. Second, they argue that undressing is invested with a special status during the examination. It is a gendered rite of passage between the two different ungendered subject positions of the doctor and the patient. They …

New Acylated Triterpene Saponins from Silene fortunei that Modulate Lymphocyte Proliferation

2002

Three new acylated triterpene saponins 1-3, with a quillaic acid as aglycon, were isolated from the roots of Silene fortunei together with a known phytoecdysteroid (20-hydroxyecdysone). The compounds were characterized mainly by a combination of 2D NMR techniques, mass spectrometry, and chemical methods. Saponins 1-3, jenisseensosides C and D (4, 5), and 6 (deacylated form of 2/3 and 4/5) were found to stimulate the proliferation of the Jurkat tumor cell lines at low concentration. At high concentration, 2/3 and 4/5 inhibited the proliferation of the cells and suggested the induction of apoptosis.

Teachers in secondary schools: evidence from TALIS 2013

2014

En ligne sur https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/322910/RR302_-_TALIS_report_NC.pdf; The Teaching and Learning International Survey (TALIS), led by the Organisation for Economic Cooperation and Development (OECD), provides new information on the views and practices of lower secondary teachers and their headteachers and on how these vary across countries. England participated in TALIS for the first time in 2013 the only part of the UK to do so. The survey included over 30 other countries or parts of countries.This national report for England is published simultaneously with the OECD's first international report on TALIS 2013. It complements the OECD's re…

Testing for hysteresis in unemployment in OECD countries. New evidence using stationarity panel tests with breaks†

2006

This paper tests hysteresis effects in unemployment using panel data for 19 Organization for Economic Co-operation and Development (OECD) countries covering the period 1956–2001. The tests exploit the cross-sectional variations of the series, and additionally, allow for a different number of endogenous breakpoints in the unemployment series. The critical values are simulated based on our specific panel sizes and time periods. The findings stress the importance of accounting for exogenous shocks in the series and support the natural-rate hypothesis of unemployment for the majority of the countries analysed.
