Purpose: To examine associations of prenatal biomarkers of pesticide exposure with birth size measures and length of gestation among newborns from the Infants' Environmental Health (ISA) birth cohort, Costa Rica. Methods: We included 386 singleton liveborn newborns with data on birth size measures, length of gestation, and maternal urinary biomarkers of chlorpyrifos, synthetic pyrethroids, mancoze

Harvest residue management is a key issue for the sustainability of Eucalyptus plantations established on poor soils. Soil microbial communities contribute to soil fertility by the decomposition of the organic matter (OM), but little is known about the effect of whole-tree harvesting (WTH) in comparison to stem only harvesting (SOH) on soil microbial functional diversity in Eucalyptus plantations.

My objective has been to characterize protein-surfactant interactions in pharmaceutically relevant formulations. Thus, the behavior of selected excipients, proteins and peptides has been studied as the system in question is driven to the verge of instability in different manners; by inducing aggregation, by inducing surfactant complexation, or by inducing precipitation by increasing ionic strength

Researchers have widely applied discharge simulation using artificial neural networks (ANNs) and have gained prominence in water resources. Morphological features, watershed urbanization, and climate change influence hydrological variables. Thus, data-driven models need to be able to identify the hydrological relationships without explicitly stating the physical processes. The main objectives of t

Large igneous provinces (LIPs) are excellent spatial and temporal geological recorders. However, our understanding of LIPs is hindered by a lack of preservation and alteration of many LIPs through deep time. Several LIPs have been emplaced in the Rhyacian. These LIPs demonstrate a connection across the Superior, Wyoming and North Atlantic cratons. In this study we use new U-Pb ID-TIMS baddeleyite

Mercury (Hg) is regarded as a major environmental concern in many regions, traditionally because of high concentrations in freshwater fish, and now also because of potential toxic effects on soil microflora. The predominant source of Hg in most watersheds is atmospheric deposition, which has increased 2- to >20-fold over the past centuries. A promising approach for supporting current European effo

An interference quenching of the nu"=1 vibrational line in the resonant Auger decay of N 1s-->pi(*) core-excited N-2 is observed and analyzed. The intensity ratio between the nu"=1 and nu"=0 vibrational levels of the X(2)Sigma(g)(+) final state shows a surprising nonmonotonous variation as a function of frequency detuning, going through a minimum with a complete suppression of nu"=1. We have devel

The SIOP nephroblastoma clinical trials have previously demonstrated that preoperative chemotherapy is advantageous for patients with nephroblastoma (Wilms' tumour). However, some primary tumours increase in size during preoperative chemotherapy, and to investigate the clinical relevance of this progression we studied the patient cohort with increasing tumours included in the SIOP 93-01 study (Jun

Ecosystems are supported by organic carbon from two distinct sources. Endogenous carbon is produced by photosynthesis within an ecosystem by autotrophic organisms. Exogenous carbon is produced elsewhere and transported into ecosystems. Consumers may use exogenous carbon with consequent influences on population dynamics, predator-prey relationships and ecosystem processes(1). For example, exogenous

Fragmentation of the SF6 molecule upon F 1s excitation has been studied by resonant photoemission. The F atomiclike Auger line exhibits the characteristic Doppler profile that depends on the direction of the photoelectron momentum relative to the polarization vector of the radiation as well as on the photon energy. The measured Doppler profiles are analyzed by the model simulation that takes accou

Despite being one of Earth's major geochemical cycles, the evolution of the silicon cycle has received little attention and changes in oceanic dissolved silica (DSi) concentration through geologic time remain poorly constrained. Silicon isotope ratios (expressed as δ30Si) in marine microfossils are becoming increasingly recognised for their ability to provide insight into silicon cycling. In parti

Several studies reported an association between CSF alpha-synuclein (α-syn) and tau in Alzheimer's disease (AD), and demonstrated the significance of α-syn in improving the diagnostic sensitivity/specificity of classical AD CSF biomarkers. In the current study, we measured CSF levels of different α-syn species in a cohort of AD patients (n = 225) who showed a CSF profile typical of AD at baseline

Lund University and Universität Hamburg: Call for proposals April 2023 – March 2025 Universität Hamburg (UHH) and Lund University (LU) have agreed to jointly support promising collaborative initiatives with pump-priming funds with the aim of leading to externally funded research, larger scale collaborations, jointly authored papers as well as common teaching activities at the advanced level (maste

Popular Abstract in English All living things have the ability to detect and respond to changes in the surrounding environment and most of us take sensations caused by changes in light, sound, taste, temperature, and touch for granted. However, the process of detection and transmission of the signal generated to the brain is quite complex and some aspects not known. This thesis explores the sensorThe ability to sense and accommodate to an ever-changing environment is crucial for the survival of living organisms. Transient Receptor Potential (TRP) ion channels comprise a large superfamily of cation conducting membrane proteins that function as molecular sensors in diverse sensory processes including perception of light, taste, smell, sound, touch and temperature. The TRP Ankyrin 1 (TRPA1) i

Human antibodies generated in vitro may be highly valuable for diagnostic and therapeutic purposes. For a long time most human antibodies produced in vitro have been of the IgM isotype with rather low affinities. In this thesis a method for production of IgG switched antigen-specific human antibodies is presented. This is a two step protocol, in which the first step is a selection procedure of don
