Abstract Visual proteomics attempts to build atlases of the molecular content of cells but the automated annotation of cryo electron tomograms remains challenging. Template matching (TM) and methods based on machine learning detect structural signatures of macromolecules. However, their applicability remains limited in terms of both the abundance and size of the molecular targets. Here we show that the performance of TM is greatly improved by using template-specific search parameter optimization ...

Lipid membranes are integral building blocks of living cells and perform a multitude of biological functions. Currently, molecular simulations of cellular-scale membrane remodeling processes at atomic resolution are extremely difficult, due to their size, complexity, and the large times-scales on which these processes occur. Instead, elastic membrane models are used to simulate membrane shapes and transitions between them and to infer their properties and functions. Unfortunately, an efficiently ...

This paper presents a new, almost fully analytical methodology for component value extraction of a double-π equivalent circuit model for three-port on-chip inductors from a given S-parameter dataset. The compact model provides an accurate fit over a wide frequency range from dc to beyond the self-resonance frequency (SRF) to a tabular input S-parameter model describing a symmetric center-tapped on-chip inductor. The input dataset may be obtained from a measurement or from an electromagnetic field ...

Orthohantaviruses are emerging rodent-borne pathogens that cause Hantavirus Pulmonary Syndrome in humans. They have a wide range of rodent reservoir hosts and are transmitted to humans through aerosolized viral particles generated by the excretions of infected individuals. Since the first description of HPS in Argentina, new hantaviruses have been reported throughout the country, most of which are pathogenic to humans. We present here the first HPS case infected with Alto Paraguay virus reported ...

Abstract Background Hantavirus Pulmonary Syndrome (HPS) is a rodent-borne zoonosis in the Americas, with up to 50% mortality rates. In Argentina, the Northwestern endemic area presents half of the annually notified HPS cases in the country, transmitted by at least three rodent species recognized as reservoirs of Orthohantavirus . The potential distribution of reservoir species based on ecological niche models (ENM) can be a useful tool to establish risk areas for zoonotic diseases. Our main aim was ...

The paper presents a new approach for state estimation of lithium–iron phosphate batteries. Lithium–iron phosphate/graphite batteries are very intricate in state of charge estimation since the open circuit voltage characteristic is flat and ambiguous. The characteristic is ambiguous because open circuit voltages are different if one charges or discharges the battery. These properties also hinder state of health estimation. Therefore conventional approaches like Kalman filtering which represents ...

Pulsed 19F ENDOR spectroscopy provides a selective method for measuring angstrom to nanometer distances in structural biology. Here, the performance of 19F ENDOR at fields of 3.4 T and 9.4 T is compared using model compounds containing one to three 19F atoms. CF3 groups are included in two compounds, for which the possible occurrence of uniaxial rotation might affect the distance distribution. At 9.4 T, pronounced asymmetric features are observed in many of the presented 19F ENDOR spectra. Data ...

Abstract As the south-westernmost region of Europe, the Iberian Peninsula stands as a key area for understanding the process of modern human dispersal into Eurasia. However, the precise timing, ecological setting and cultural context of this process remains controversial concerning its spatiotemporal distribution within the different regions of the peninsula. While traditional models assumed that the whole Iberian hinterland was avoided by modern humans due to ecological factors until the retreat ...

We report two complete foamy retrovirus (FV) genomes isolated from Puma concolor, a large cat native to the Americas. Due to high overall genetic relatedness to known feline foamy viruses (FFVs), we propose the name Puma concolor FFV (FFVPc). The data confirm that felines are infected with distinct but closely related FVs.

Abstract In this short report we discuss the temporal association between an acute life threatening event (ALTE) and a RT‐PCR confirmed coronavirus HCoV‐229E infection in a 4 months old otherwise healthy infant. More detailed microbiological investigations of affected children even without apparent signs of a respiratory tract infection may help to clarify the etiology in some patients and extend our understanding of the pathogenesis. PCR‐based techniques should be utilized to increase the sensitivity ...

(Abstracted from Ultrasound Obstet Gynecol 2016;47:674–679) One of the important aspects of fetal well-being assessment is amniotic fluid volume, lack of which leads to oligohydramnios and consequently adverse perinatal outcomes. Amniotic fluid estimation by ultrasound can be performed by assessment of the amniotic fluid index (AFI) or the single deepest vertical pocket (SDP) technique.

Multiple myeloma (MM) is a hematological malignancy originating from malignant and clonally expanding plasma cells. MM can be molecularly stratified, and its clonal evolution deciphered based on the Ig heavy and light chains of the respective malignant plasma cell clone. Of all MM subtypes, IgE type MM accounts for only <0.1% of cases and is associated with an aggressive clinical course and consequentially dismal prognosis. In such malignancies, adoptive transfer of autologous lymphocytes specifically ...

With the onset of the Last Glacial Maximum (LGM), hunter-gatherers of the so-called Iberomaurusian techno-complex appeared in what is now the Mediterranean Maghreb. During a period of about seven thousand years, these groups left sandy occupation layers in a limited number of archaeological sites, while at the beginning of Greenland Interstadial (GI) 1, the sudden shift towards the deposition of shell-rich sediments and the increase in number of sites document clear changes in subsistence strategies ...

Non-selective NSAIDs can cause serious gastrointestinal side-effects. Selective COX-2 blockers are a reasonable alternative for pain treatment. They do not seem to affect platelet function and consequently cause a lower perioperative blood loss than non-selective NSAIDs. This study compared etoricoxib and diclofenac during a perioperative (9 days) period after THA to investigate total blood loss and gastrointestinal tolerability. The hypothesis was that etoricoxib is superior to diclofenac.A total ...
