Background: Stroke is a rare disorder in childhood; among its risk factors, C677T mutations in the methylenetetrahydrofolate reductase (MTHFR) gene with secondary hyperhomocysteinemia are considered. Patients and methods: We report on a family in which two brothers had arterial ischemic stroke (AIS). One of these siblings came to our observation at the age of 4 years because of decreased motility
In 18 untreated adult patients (median age 62.5 yr) with advanced non‐Hodgkin's lymphoma of unfavourable histology, thymidine labelling indices (LIs) of the lymphoma cells were assessed. The patients were treated with combination chemotherapy and have been followed for 29–60 (median 52) months or until death. The survival curve had a steep fall during the first 2 yr. Between 2–5 yr after treatment
Despite increasing access to antiretroviral treatment (ART) in low-income countries, HIV-related mortality is high, especially in the first months following ART initiation. We aimed to evaluate the impact of TB coinfection on early mortality and to assess gender-specific predictors of mortality in a cohort of Ethiopian adults subjected to intensified casefinding for active TB before starting ART.
Recognition and removal of apoptotic and necrotic cells must be efficient and highly controlled to avoid excessive inflammation and autoimmune responses to self. The complement system, a crucial part of innate immunity, plays an important role in this process. Thus, apoptotic and necrotic cells are recognized by complement initiators such as C1q, mannose binding lectin, ficolins, and properdin. Th
Purpose: The aims of this study were to assess the short- and long-term complication rates after video-assisted gastrostomy (VAG), the effects of age and gender on long-term complications and the effect of duration of gastrostomy tube retention on the need for gastroraphy when the gastrostomy device was removed. Methods: This was a retrospective study of children undergoing VAG at a single institu
Histones become present extracellularly in the airways as a consequence of celldeathoccurring during inflammation, for example in ARDS, COPD, and cysticfibrosis (CF). Extracellular histones bind Toll-like receptors and thereby promoteinflammation. In addition, due to their highly cationic nature, histones are highlycytotoxic. Thus, mechanisms controlling the activities of extracellular histones ar
The objective of this prospective study of matched controls was to find out whether supplementary nutrition would improve wound healing and decrease mortality in patients undergoing transtibial amputation for occlusive arterial disease. The nutritional status of 32 consecutive transtibial amputees was assessed and 28 were classified as malnourished. Supplementary nutrition was given reaching an av
S100 protein is a marker for brain damage easily analysed in blood. The serum level immediatly after termination of extracorporeal circulation (ECC) is increased and associated to age and the duration of perfusion. A prolonged residual concentration indicates cellular brain damage. The objective of this study was to ascertain if the prognosis of individual patients, with stroke following ECC, coul
Inbreeding increases the level of homozygosity, which in turn might depress fitness. In addition, individuals having the same inbreeding coefficient (e.g. siblings) vary in homozygosity. The potential fitness effects of variation in homozygosity that is unrelated to the inbreeding coefficient have seldom been examined. Here, we present evidence from wild birds that genetic variation at five micros
This paper presents a 28 GHz QVCO intended to be used in an 81-86 GHz E-band transceiver. E-band transceivers using e.g. 16 QAM modulation schemes are sensitive to I/Q phase error. Already a three degree error significantly degrades the bit error rate, and careful control of the phase error of the 28 GHz QVCO is therefore required. In the presented design the phase error can be tuned using four va
This essay examines 15 news articles published in the Swedish magazine Svensk Bokhandel during the year of 2019. Qualitative linguistic analysis is used to examine what and how the magazine writes about publishing and the book market. The questions asked are: Which themes, messages, ulterior ideas and attitudes are mediated through the articles? And is there a crisis discourse in publishing? The r
This volume focuses on the interaction of lichens with their substrate, environment and their biogeographic effects. In seventeen chapters thirty-eight authors present recent fi ndings and developments in systematics, biodiversity, fl oristic studies and ecology, as well as newly described taxa, and keys to the identifi cation of Caloplaca and xanthorioid lichens. Molecular phylogenetic analyses o
Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. This movement is called migration, and the migration velocity depends on the acoustic mobility of the particle, which depend on the particle s
Observed population of giant planets around evolved stars shows a paucity of planets with semi-major axes below 0.5 au, in contrast to main sequence stars where those planets are present. This lack of close-in planets has been attributed to either planet engulfment due to tidal forces or substantially higher masses of evolved host stars implying dierent initial semi-major axis distributions, becau
This study aims to look at the link between in utero malnutrition and the survival probabilities of fetuses and newborns, using the 2002 food shortages in Malawi as an instrument for malnutrition. Concretely, it looks at differences in the probability of a born child being a male and in neonatal mortality between children in utero affected by food scarcity and those born right before and after the
The purpose of the study is to investigate how much interest media has shown selected topics in the corporate governance systems in Germany and Sweden. The four selected aspects are: ownership structure, employee representation on the boards, disclosure of board members’ compensation and female directors on the boards. The reasons for and consequences of the similarities and differences will also
