INTRODUCTION: Interventional oncology locoregional therapies are validated treatment modalities for primary and secondary tumors in liver, lung, kidney and bone. At this time, there is no accordance in the choice of imaging modality to assess treatment response. Morphological imaging and RECIST 1.1 criteria based on size variation are limited by several critical points. On the other hand the role of functional imaging, in particular by [18F]-fluorodeoxyglucose ([18F]-FDG) positron emission tomography (PET), in both staging and response evaluation of locoregional treatments remains unclear because of the heterogeneous nature of available data...

BACKGROUND: Recently, four neuropathological stages of amyotrophic lateral sclerosis (ALS) with spreading of transactive response DNA-Binding Protein-43 pathology were described. Although 18F-FDG PET has been useful in diagnosis and prognosis of ALS patients, in vivo disease staging using glucose metabolic patterns across the different ALS stages have not been attempted so far. In this study, we investigated whether the discriminant brain regions of the neuropathological stage model can be translated to metabolic patterns for in vivo staging of ALS...

Monoamines, acting as hormones and neurotransmitters, play a critical role in multiple physiological processes ranging from cognitive function and mood to sympathetic nervous system activity, fight-or-flight response, or glucose homeostasis. In addition to brain and blood, monoamines are abundant in several tissues, and dysfunction in their synthesis or signaling is associated with various pathological conditions. It was our goal to develop a method to detect these compounds in peripheral murine tissues. In this study, we employed a high performance liquid chromatography method using electrochemical detection that allows not only detecting the catecholamines but a detailed analysis of nine monoamines and metabolites in murine tissues...

Multiple sclerosis (MS), a chronic progressive inflammatory disease of the central nervous system, causes frequent disability, mood disorders, fatigue, and cognitive dysfunction. As a part of the last, social cognition is frequently disturbed in MS patients. It comprises empathy and social perception of emotions from facial, bodily and vocal cues. Social cognitive deficits worsen affect decoding, interpersonal relationship, and quality of life. Despite the impact of these deficits on global functioning, only a small number of studies have investigated its correlations and overlaps with MS symptoms...

Aim CoCrMo alloys are contraindicated for sufferers from allergy. For these patients, uncemented and cemented prostheses made of non-allergenic titanium alloy are indicated. Knee prostheses machined from that alloy, however, may have poor tribological behaviour, especially in contact to UHMWPE inlays. Therefore, high-strength oxide ceramics may be especially suitable for knee replacement in allergy patients with mobile bearing prostheses. For adhesion to bone cement, the ceramic surface only exhibits mechanical retention spots that are less adequate than those with a textured metal surface...

Pseudomonas aeruginosa is a Gram-negative pathogen that can lead to severe infection associated with lung injury and high mortality. The interleukin (IL)-36 cytokines (IL-36α, IL-36β and IL-36γ) are newly described IL-1 like family cytokines that promote inflammatory response via binding to the IL-36 receptor (IL-36R). Here we investigated the functional role of IL-36 cytokines in the modulating of innate immune response against P. aeruginosa pulmonary infection. The intratracheal administration of flagellated cytotoxic P...

Scaffold proteins are ubiquitous chaperones that promote efficient interactions between partners of multi-enzymatic protein complexes; although they are well studied in eukaryotes, their role in prokaryotic systems is poorly understood. Bacterial membranes have functional membrane microdomains (FMM), a structure homologous to eukaryotic lipid rafts. Similar to their eukaryotic counterparts, bacterial FMM harbor a scaffold protein termed flotillin that is thought to promote interactions between proteins spatially confined to the FMM...

Here we determine the sex-specific influence of mtDNA type (mitotype) and diet on mitochondrial functions and physiology in two Drosophila melanogaster lines. In many species, males and females differ in aspects of their energy production. These sex-specific influences may be caused by differences in evolutionary history and physiological functions. We predicted the influence of mtDNA mutations should be stronger in males than females as a result of the organelle's maternal mode of inheritance in the majority of metazoans...

Episodic Future Thinking has proven efficient in reducing impulsive behavior in several adult populations. Whether it also has a beneficial impact on decision making in adolescents is not known. Here the impact of episodic future thinking on discounting behavior was investigated in a sample of healthy adolescents (n = 44, age range 13-16 years). Discounting behavior in trials including episodic future thinking was significantly less impulsive than in control trials (t = 2.74, p = .009, dz = .44). In a subsample we controlled for executive function, alcohol use and developmental measures...

For a given gene, different mutations influence organismal phenotypes to varying degrees. However, the expressivity of these variants not only depends on the DNA lesion associated with the mutation, but also on factors including the genetic background and rearing environment. The degree to which these factors influence related alleles, genes, or pathways similarly, and whether similar developmental mechanisms underlie variation in the expressivity of a single allele across conditions and among alleles is poorly understood...

We present paleo-water depth reconstructions for the Pefka E section deposited on the island of Rhodes (Greece) during the early Pleistocene. For these reconstructions, a transfer function (TF) using modern benthic foraminifera surface samples from the Adriatic and Western Mediterranean Seas has been developed. The TF model gives an overall predictive accuracy of ~50 m over a water depth range of ~1200 m. Two separate TF models for shallower and deeper water depth ranges indicate a good predictive accuracy of 9 m for shallower water depths (0-200 m) but far less accuracy of 130 m for deeper water depths (200-1200 m) due to uneven sampling along the water depth gradient...

Correct detection of membrane currents under whole-cell patch-clamp conditions is limited by the transfer function of a recording system. The low-pass output filter of a recording amplifier alters the time course of membrane current and causes errors in relevant descriptors. To solve these problems, we developed a practical procedure for reconstruction of the time course of membrane currents based on deconvolution of recorded currents in frequency domain. The procedure was tested on membrane capacitance estimates from current responses to step voltage pulses...

BACKGROUND: APOBECs (apolipoprotein B mRNA-editing catalytic polypeptides) are cytidine deaminases that have been implicated in the host defense against viruses by blocking viral replication. They have also been shown to play a role in genome hypermutation in several human cancers. An APOBEC3 hypermutation signature has been discovered in cervical cancer, which is intimately associated with infection by high-risk human papillomaviruses (HPVs). At the same time, HPV genomes themselves are subject to DNA editing by APOBECs...
