Obesity has been associated with upper gastrointestinal cancers; however, there are limited prospective data on associations by subtype/subsite. Obesity can impact hormonal factors, which have been hypothesized to play a role in these cancers. We investigated anthropometric and reproductive factors in relation to esophageal and gastric cancer by subtype and subsite for 476,160 participants from th
Background: Embolic stroke of undetermined source (ESUS) identifies patients with cryptogenic ischemic stroke presumed due to embolism from several unidentified sources. Among patients with recent ESUS, we sought to determine independent predictors of recurrent ischemic stroke during treatment with aspirin or rivaroxaban and to assess the relative effects of these treatments according to risk. Met
Introduction: We estimated the age-specific duration of the preclinical, prodromal, and dementia stages of Alzheimer's disease (AD) and the influence of sex, setting, apolipoprotein E (APOE) genotype, and cerebrospinal fluid tau on disease duration. Methods: We performed multistate modeling in a combined sample of 6 cohorts (n = 3268) with death as the end stage and estimated the preclinical, prod
Drawing on participant methodologies this article examines two cases of workers’ self-organised projects oriented to improving the quality of sex work and to ‘professionalisation’. The first case is a group of sexual assistants for people with disabilities, who have organised meetings and training for sexual assistants in a medium-sized city in Switzerland. The second is a group of peer sex worker
Background: Treatment of bile duct injuries (BDI)during cholecystectomy depends on the severity of injury and the timing of diagnosis. Standard of care for severe BDIs is hepaticojejunostomy. The aim of this retrospective multi-center study was to assess the optimal timing for repair of BDI with hepaticojejunostomy. Methods: Members of the European-African HepatoPancreatoBiliary Association were i
Background:Little is known about hip-related function, mobility, and performance in patients after hip arthroscopic surgery (HA) during the time that return to sports can be expected.Purpose:To evaluate measures of subjective and objective hip function 6 to 10 months after HA in patients compared with healthy controls and to compare objective function in the HA group between the operated and nonop
Molecularly imprinted polymers have been prepared in various configurations including, for example, polymer beads, monoliths and membranes for different applications. The most common form of imprinted polymer is, however, still the irregularly shaped particle obtained by grinding the traditional, macroporous polymer monolith. We herein present a novel and efficient approach leading to imprinted mi
In France, illegal hunting of the endangered ortolan bunting Emberiza hortulana has been defended for the sake of tradition and gastronomy. Hunters argued that ortolan buntings trapped in southwest France originate from large and stable populations across the whole of Europe. Yet, the European Commission referred France to the Court of Justice of the European Union (EU) in December 2016 for infrin
Molecular imprinting is an emerging technique for preparing artificial antibodies that have potential applications in affinity-based separations, biomimetic sensors and assays. The conventional imprinting methods either deliver a monolith that is mechanically ground to irregular particles - a time-consuming process with low yield, or involves complicated polymerization process by which spherical b
A flow injection competitive assay analogous to enzyme immunoassays has been developed using a molecularly imprinted polymer instead of the antibody. A glass capillary was modified by covalently attaching an imprinted polymer to the inner capillary wall. The herbicide 2,4-dichlorophenoxyacetic acid was used as a model analyte. The analyte was labeled with tobacco peroxidase, and chemiluminescence
An imaging assay analogous to competitive enzyme immunoassays has been developed using a molecularly imprinted polymer instead of an antibody. The antigen 2,4-dichlorophenoxyacetic acid (2,4-D) was labeled with tobacco peroxidase, and the chemiluminescence reaction of luminol was used for detection. Microtiter plates (96 or 384 wells) were coated with polymer microspheres imprinted with 2,4-D, whi
Molecularly imprinted polymers are prepared using various steroid compounds as the templates. The imprinted polymers can selectively re-bind the original print molecules, which leads to versatile potential applications. The feasibility of using these artificial receptors to replace their biological counterparts for preliminary screening of a chemical library is demonstrated. A steroid library comp
Molecularly imprinted polymers (MIPs) are applicable in a variety of different configurations. For example, bulk polymers imprinted with β-lactam antibiotics are presented to be used as stationary phases for the chromatographic separation of β-lactam antibiotics with both aqueous and organic mobile phases. However, in some analytical applications, monosized spherical beads are preferred over the c
Based on a molecularly imprinted polymer, a competitive binding assay analogous to competitive enzyme immunoassay has been developed. The assay is specific for the herbicide 2,4-dichlorophenoxyacetic acid and uses, for the first time, an enzyme-labelled conjugate as a tracer. The label tobacco peroxidase allowed for colorimetric and chemiluminescence detection. The molecularly imprinted polymer wa
Molecularly imprinted polymers are highly stable and can be sterilised, making them ideal for use in biotransformation process. In this communication, we describe a novel application of molecularly imprinted polymers in an enzymatic reaction. The enzymatic condensation of Z-L-aspartic acid with L-phenylalanine methyl ester to give Z-L-Asp-L-Phe-OMe (Z- aspartame) was chosen as a model system to ev
In the present study, molecularly imprinted affinity sorbents against theophylline and 17β-estradiol are synthesised via precipitation polymerisation, a synthetic method that yields monodisperse, spherical polymer particles in the micronscale range, quickly, cleanly and in good yield. The specific binding sites that are created during the imprinting process are analysed via radioligand binding ana
We have studied the possibility of shifting a thermodynamically unfavourable enzymatic equilibrium towards product formation via the addition of a highly specific adsorbent. The commercially interesting enzymatic condensation of Z-L-aspartic acid with L-phenylalanine methyl ester to the sweetener aspartame was chosen as the model system. Extremely stable and specific adsorbents for the product Z-L
Molecular imprinting is an attractive method for producing highly selective adsorbents, and several new and potentially useful applications based on molecularly imprinted polymers (MIPs) have been described in recent years. In this article, we highlight some of the areas where these materials have found application, and also describe some new fields of application where the selectivities of imprin
