Normal frequency of structural chromosome aberrations in fibroblasts from patients with non‐Hodgkin's lymphoma

The incidence of chromosome aberrations, i.e., chromatid and chromosome gaps, breaks, and exchanges, was studied in cultured skin fibroblasts from 25 untreated patients with non‐Hodgkin's lymphoma (NHL) and 26 controls. The mean frequencies of aberrant cells, and gap, break, and gap+break events per 100 metaphases were 4.2, 1.9, 2.8, and 4.7 in the NHL group, and 5.1, 2.6, 3.2, and 5.8 in the cont

A “noble battle against darkness, sin, and depravity” : The role of translation in nineteenth-century transnational transfer of philanthropic ideas

Nineteenth-century British philanthropic ideas were implemented in Sweden through the agency of translation. The present investigation of translation as a form of nineteenth-century social-reform activism takes the form of a case study of the Swedish translation of two texts by British social purity campaigner Ellice Hopkins (1836–1904).

Farnesylated heat shock protein 40 is a component of membrane-bound RISC in Arabidopsis

ARGONAUTE1 (AGO1) binds directly to small regulatory RNA and is a key effector protein of post-transcriptional gene silencing mediated by microRNA (miRNA) and small interfering RNA (siRNA) in Arabidopsis. The formation of an RNA-induced silencing complex (RISC) of AGO1 and small RNA requires the function of the heat shock protein 70/90 chaperone system. Some functions of AGO1 occur in association

Trisomy 5 and t(5;14)(q11;q32) as the sole abnormalities in two different clones from a centroblastic non-Hodgkin's lymphoma

A 62-year-old previously healthy woman presented with a centroblastic non-Hodgkin's lymphoma in the thyroid. Chromosome analysis revealed two unrelated clones, 47,XX,+5 and 46,XX,-14,+der(14)t(5;14)(q11;q32). The two clones may reflect a polyclonal origin, or they may be the descendants of the same neoplastically rearranged cell. In the latter case, the clonal aberrations are either secondary to a

Maximal haemostatic effect is attained in porcine skin within 7 minutes of the administration of a local anaesthetic together with epinephrine, refuting the need for a 30-minute waiting time

Objective Based on clinical experience gained over many years, the maximal haemostatic effect following administration of local anaesthetics containing epinephrine is generally believed to occur within 10 minutes. Surprisingly, it was found in a recent study, in which bleeding was quantified intraoperatively, that maximal haemostasis did not occur until 30 minutes. If this is indeed the case, the

Searching with and against each other : Spatiotemporal coordination of visual search behavior in collaborative and competitive settings

Although in real life people frequently perform visual search together, in lab experiments this social dimension is typically left out. Here, we investigate individual, collaborative and competitive visual search with visualization of search partners' gaze. Participants were instructed to search a grid of Gabor patches while being eye tracked. For collaboration and competition, searchers were show

Costs and quality of life for prehabilitation and early rehabilitation after surgery of the lumbar spine

During the recent years improved operation techniques and administrative procedures have been developed for early rehabilitation. At the same time preoperative lifestyle intervention (prehabilitation) has revealed a large potential for additional risk reduction. The aim was to assess the quality of life and to estimate the cost-effectiveness of standard care versus an integrated programme includin

Automatic Control in Wastewater Treatment Plants

Process dynamics and control in biological waste water treatment operations are considered. Particular emphasis has been put on the control of dissolved oxygen and its spatial distribution in activated sludge aerators. It is demonstrated how dissolved oxygen profiles can be used for the estimation of the biodegradable load. Aspects of the control of chemical precipitation are discussed as well.

Futures as seen from the diaspora – the Syria 2040 workshops

The Syria 2040 workshops were initiated in 2016 by the International Institute for Industrial Environmental Economics and the Centre for Middle Eastern Studies, Lund University, and ran for one and a half years, using scenario methodology. Syrians with diverse backgrounds and political standpoints, living in Sweden and other European countries, collectively reflected on possible scenarios for futu

Physical bounds and radiation modes for MIMO antennas

Modern antenna design for communication systems revolves around two extremes: devices, where only a small region is dedicated to antenna design, and base stations, where design space is not shared with other components. Both imply different restrictions on what performance is realizable. In this paper properties of both ends of the spectrum in terms of MIMO performance is investigated. For small a

Wearable comfort and performance expectancy predict user acceptance of a sensor-based home lighting system

The aim was to evaluate an early prototype of a personalised home lighting system comprising body-worn loggers, a mobile phone, and LED-based lighting with variable intensity and colour temperature. A convenience sample (N = 28, 50% female) wore the devices for 24 hours in the field and were given a demonstration of the lighting system components in a full-scale model of a studio apartment.

Experimental Study and a Short Kinetic Model for High-Temperature Oxidation of Methyl Methacrylate

Synthetic and natural polymeric esters find applications in transport and construction sectors, where fire safety is an important concern. One polymer that is widely used is poly (methyl methacrylate) (PMMA), which almost completely undergoes thermal decomposition into methyl methacrylate (its monomer) CH2=C(CH3) - C(= O) - O - CH3 (MMA) at ~250–300°C. In order to analyze the high-temperature gas-
