Sixty-five strains and isolates of Agrobacterium tumefaciens representing each of the known biotypes, were tested for in vitro and in vivo susceptibility to the agrocin-producing strains Agrobacterium radiobacter 84 and A. tumefaciens D286. No biotype 3 strain was susceptible to the effects of either of the agrocinogenic strains in vitro. On datura and tobacco, the best inhibition of tumor formation was obtained when the agrocinogenic strains were applied to wounds 24 h before the pathogens and ...

There is little empirical evidence on children's subjective experiences of discomfort during clinical research procedures. Therefore, Institutional Review Boards have limited empirical information to guide their decision-making on discomforts for children in clinical research. To get more insight into what children's discomforts are during clinical research procedures, we interviewed a group of children on this topic and also asked for suggestions to reduce possible discomforts. Forty-six children ( ...

Objective The evaluation of discomfort in paediatric research is scarcely evidence-based. In this study, we make a start in describing children's self-reported discomfort during common medical research procedures and compare this with discomfort during dental check-ups which can be considered as a reference level of a ‘minimal discomfort’ medical procedure. We exploratory study whether there are associations between age, anxiety-proneness, gender, medical condition, previous experiences and discomfort. ...

Given the number of global malaria cases and deaths, the need for a vaccine against Plasmodium falciparum (Pf) remains pressing. Administration of live, radiation-attenuated Pf sporozoites can fully protect malaria-naïve individuals. Despite the fact that motility of these attenuated parasites is key to their infectivity and ultimately protective efficacy, sporozoite motility in human tissue (e.g. skin) remains wholly uncharacterized to date. We show that the ability to quantitatively address the ...

Introduction: The skin stage of malaria is a vital and vulnerable migratory life stage of the parasite. It has been characterised in rodent models, but remains wholly uninvestigated for human malaria parasites. To enable in depth analysis of not genetically modified (non-GMO) Plasmodium falciparum (Pf) sporozoite behaviour in human skin, we devised a labelling technology (Cy5M2, targeting the sporozoite mitochondrion) that supports tracking of individual non-GMO sporozoites in human skin. Methods: ...

There is a need for data on children's self-reported discomfort in clinical research, helping ethics committees to make their evaluation of discomfort described in study protocols evidence-based. Since there is no appropriate instrument to measure children's discomfort during medical research procedures, we aimed to develop a generic, short and child-friendly instrument: the DISCO-RC questionnaire (DISCOmfort in Research with Children). This article describes the six steps of the development of the ...

Abstract To determine the perception of children with inflammatory bowel disease (IBD) regarding monitoring tests, we first compared the reported discomfort and patient perspective during gastro-intestinal (GI)-endoscopy, magnetic resonance entrography (MRE), and ultrasound (US) and, in a second comparison, patient preference on non-invasive tests (venipuncture, sampling stool and US). A cross-sectional study in children 8–18 years undergoing an US, MRE, and GI-endoscopy for diagnosis or follow-up of ...

Although the field of Bushman studies has seen a number of different disciplines being drawn upon to address key questions, the textual material of the Bleek and Lloyd archive is still relatively understudied. Studies which do approach this material, however, tend to do so through an anthropological and/or archaeological lens, with literary analysis often marginalized. This article, through taking account of considerations of the reception theories developed in literary studies, criticises the various ...

Bacterial blight, caused by Xylophilus ampelinus (PANAGOPOULUS) WILLEMS et al. is a destructive disease of grapevine ( Vitis vinifera ). Incubation of cuttings at 15 °C for three days under moist conditions significantly increased the number of isolated X. ampelinus colonies. This treatment facilitates the isolation of the pathogen from infected material from which it could previously not be isolated.

Background Conducting non-therapeutic research is ethically challenging because participation conveys risks and burden and no health benefit. In this paper, we report the positive experiences of a diverse group of healthy and ill children (6–18 years) who participated in non-therapeutic research studies and discuss whether these positive experiences can justifiably be viewed as benefits. Methods We used semistructured interviews from an earlier study about children9s experiences in clinical research and did ...

Research in children should strike the right balance between protecting underage study subjects and advancing the medical field. This study gives insight into the emotional burden that common invasive research procedures in asthma research have on young children, both from the child and parent perspective. Puppetry was used to stimulate children (age 5–6 years) to explain their emotional burden prior to and after the research procedures. We operationalised emotional burden as willingness to participate ...

This article investigates the problematic position of Bushman heritage. Acknowledging the importance of this heritage in itself, but further as unmissable against the backdrop of calls for the decolonisation of knowledge in South Africa, a discourse of indigenous rights appears as the most just and suitable tool for analysis and critical reflection. Indigenous rights, however, proves to be quite problematic unto itself. This article offers a critique of the framework of indigenous rights, and offers ...

Abstract Aims It is essential to exclude a periprosthetic joint infection (PJI) prior to revision surgery. It is recommended to routinely aspirate the joint before surgery. However, this may not be necessary in a subgroup of patients. The aim of our study was to investigate if specific clinical and implant characteristics could be identified to rule out a PJI prior to revision surgery. Methods We retrospectively evaluated clinical and implant characteristics of patients who underwent a hip or knee ...
