Half body irradiation (HBI) for bone metastases in the modern radiotherapy technique era - A systematic review.

Bone metastases (BMs) are the most common cause of cancer-related pain and radiation therapy plays a key role in treating pain caused by it. The half-body irradiation (HBI) is a modality that can be used to treat patients with multiple painful BMs. In the modern era, concerns about toxicity and the availability of new agents requiring robust bone marrow function have limited the use of HBI in advanced cancer.

New Pharmacological Therapies in the Treatment of Epilepsy in the Pediatric Population.

Epilepsy is a disorder characterized by abnormal brain neuron activity, predisposing individuals to seizures. The International League Against Epilepsy (ILAE) categorizes epilepsy into the following groups: focal, generalized, generalized and focal, and unknown. Infants are the most vulnerable pediatric group to the condition, with the cause of epilepsy development being attributed to congenital brain developmental defects, white matter damage, intraventricular hemorrhage, perinatal hypoxic-ischemic injury, perinatal stroke, or genetic factors such as mutations in the Sodium Channel Protein Type 1 Subunit Alpha () gene.

Microbial Transformations of Halolactones and Evaluation of Their Antiproliferative Activity.

The microbial transformations of lactones with a halogenoethylocyclohexane moiety were performed in a filamentous fungi culture. The selected, effective biocatalyst for this process was the AM177 strain. The lactones were transformed into the hydroxy derivative, regardless of the type of halogen atom in the substrate structure.

Machine learning on the road to unlocking microbiota's potential for boosting immune checkpoint therapy.

The intestinal microbiota is a complex and diverse ecological community that fulfills multiple functions and substantially impacts human health. Despite its plasticity, unfavorable conditions can cause perturbations leading to so-called dysbiosis, which have been connected to multiple diseases. Unfortunately, understanding the mechanisms underlying the crosstalk between those microorganisms and their host is proving to be difficult.

A faecal microbiota signature with high specificity for pancreatic cancer.

Background: Recent evidence suggests a role for the microbiome in pancreatic ductal adenocarcinoma (PDAC) aetiology and progression.

Objective: To explore the faecal and salivary microbiota as potential diagnostic biomarkers.

Methods: We applied shotgun metagenomic and 16S rRNA amplicon sequencing to samples from a Spanish case-control study (n=136), including 57 cases, 50 controls, and 29 patients with chronic pancreatitis in the discovery phase, and from a German case-control study (n=76), in the validation phase.

Advanced Dental Cleaning is Associated with Reduced Risk of COPD Exacerbations - A Randomized Controlled Trial.

Purpose: Infections from the oral microbiome may lead to exacerbations of chronic obstructive pulmonary disease (COPD). We investigated whether advanced dental cleaning could reduce exacerbation frequency. Secondary outcomes were disease-specific health status, lung function, and whether the bacterial load and composition of plaque microbiome at baseline were associated with a difference in outcomes.

Microbiome meta-analysis and cross-disease comparison enabled by the SIAMCAT machine learning toolbox.

The human microbiome is increasingly mined for diagnostic and therapeutic biomarkers using machine learning (ML). However, metagenomics-specific software is scarce, and overoptimistic evaluation and limited cross-study generalization are prevailing issues. To address these, we developed SIAMCAT, a versatile R toolbox for ML-based comparative metagenomics.

Meta-analysis of fecal metagenomes reveals global microbial signatures that are specific for colorectal cancer.

Association studies have linked microbiome alterations with many human diseases. However, they have not always reported consistent results, thereby necessitating cross-study comparisons. Here, a meta-analysis of eight geographically and technically diverse fecal shotgun metagenomic studies of colorectal cancer (CRC, n = 768), which was controlled for several confounders, identified a core set of 29 species significantly enriched in CRC metagenomes (false discovery rate (FDR) < 1 × 10).

FitTetra 2.0 - improved genotype calling for tetraploids with multiple population and parental data support.

Background: Genetic studies in tetraploids are lagging behind in comparison with studies of diploids as the complex genetics of tetraploids require much more elaborated computational methodologies. Recent advancements in development of molecular techniques and computational tools facilitate new methods for automated, high-throughput genotype calling in tetraploid species. We report on the upgrade of the widely-used fitTetra software aiming to improve its accuracy, which to date is hampered by technical artefacts in the data.

Computational identification of co-evolving multi-gene modules in microbial biosynthetic gene clusters.

The biosynthetic machinery responsible for the production of bacterial specialised metabolites is encoded by physically clustered group of genes called biosynthetic gene clusters (BGCs). The experimental characterisation of numerous BGCs has led to the elucidation of subclusters of genes within BGCs, jointly responsible for the same biosynthetic function in different genetic contexts. We developed an unsupervised statistical method able to successfully detect a large number of modules (putative functional subclusters) within an extensive set of predicted BGCs in a systematic and automated manner.

Perinatal and lifestyle factors mediate the association between maternal education and preschool children's weight status: the ToyBox study.

Objective: This study aimed to explore the associations among perinatal, sociodemographic, and behavioral factors and preschool overweight/obesity.

Methods: Data were collected from 7541 European preschoolers in May/June 2012. Children's anthropometrics were measured, and parents self-reported all other data via questionnaires.

reGenotyper: Detecting mislabeled samples in genetic data.

In high-throughput molecular profiling studies, genotype labels can be wrongly assigned at various experimental steps; the resulting mislabeled samples seriously reduce the power to detect the genetic basis of phenotypic variation. We have developed an approach to detect potential mislabeling, recover the "ideal" genotype and identify "best-matched" labels for mislabeled samples. On average, we identified 4% of samples as mislabeled in eight published datasets, highlighting the necessity of applying a "data cleaning" step before standard data analysis.

Pheno2Geno - High-throughput generation of genetic markers and maps from molecular phenotypes for crosses between inbred strains.

Background: Genetic markers and maps are instrumental in quantitative trait locus (QTL) mapping in segregating populations. The resolution of QTL localization depends on the number of informative recombinations in the population and how well they are tagged by markers. Larger populations and denser marker maps are better for detecting and locating QTLs.

Establishing a method to estimate the cost-effectiveness of a kindergarten-based, family-involved intervention to prevent obesity in early childhood. The ToyBox-study.

Overweight and obesity in children are recognized as a major health problem. The ToyBox-intervention was developed with the aim of preventing obesity in pre-schoolers. Because it is increasingly important to inform policy makers not only on the effects of prevention interventions, but also on their costs and cost-effectiveness, our purpose was to establish a method to estimate the cost-effectiveness of the ToyBox-intervention.

Developing the intervention material to increase physical activity levels of European preschool children: the ToyBox-study.

Early childhood is an important period for adopting positive health-related behaviours. More than 95% of European preschool children attend kindergartens, making these settings ideal for the implementation of health promotion interventions. The ToyBox-intervention addressed preschool children, their parents/caregivers and teachers.

WormQTLHD--a web database for linking human disease to natural variation data in C. elegans.

Interactions between proteins are highly conserved across species. As a result, the molecular basis of multiple diseases affecting humans can be studied in model organisms that offer many alternative experimental opportunities. One such organism-Caenorhabditis elegans-has been used to produce much molecular quantitative genetics and systems biology data over the past decade.

Influencing factors of sedentary behavior in European preschool settings: an exploration through focus groups with teachers.

Background: Sedentary behavior refers to activities involving sitting down and reclining (eg, watching TV, using the computer) and has been associated with different health outcomes. In preschool, children are sedentary for 50% to 80% of the time, in the classroom as well as during recess. Because of the absence of qualitative studies examining influencing factors of preschoolers' sedentary behavior in preschool settings, this study explored teachers' opinions on potentially influencing factors of this behavior.

Structure of the alanopine-containing O-polysaccharide and serological cross-reactivity of the lipopolysaccharide of Proteus vulgaris HSC 438 classified into a new Proteus serogroup, O76.

The O-polysaccharide was isolated by mild acid hydrolysis of the lipopolysaccharide of Proteus vulgaris HSC 438, and the following structure was established by chemical methods and one- and two-dimensional (1)H and (13)C NMR spectroscopy: →3)-β-d-Quip4NAlo-(1→3)-α-d-Galp6Ac-(1→6)-α-d-Glcp-(1→3)-α-l-FucpNAc-(1→3)-β-d-GlcpNAc-(1→, where d-Qui4N stands for 4-amino-4,6-dideoxy-d-glucose and Alo for N-((S)-1-carboxyethyl)-l-alanine (alanopine); only about half of the Gal residues are O-acetylated. This structure is unique among the Proteus O-polysaccharides, and therefore it is proposed to classify P. vulgaris HSC 438 into a new Proteus serogroup, O76.

Physical activity and beverage consumption in preschoolers: focus groups with parents and teachers.

Background: Qualitative research is a method in which new ideas and strategies can be discovered. This qualitative study aimed to investigate parents' and teachers' opinions on physical activity and beverage consumption of preschool children. Through separate, independent focus groups, they expressed their perceptions on children's current physical activity and beverage consumption levels, factors that influence and enhance these behaviours, and anticipated barriers to making changes.

Influencing factors of screen time in preschool children: an exploration of parents' perceptions through focus groups in six European countries.

Preschoolers already spend significant proportions of their waking hours being sedentary. Screen time (i.e.

Serological and structural characterization of the O-antigens of the unclassified Proteus mirabilis strains TG 83, TG 319, and CCUG 10700 (OA).

Introduction: Lipopolysaccharide (endotoxin, LPS) is an important potential virulence factor of Proteus rods. The serological specificity of the bacteria is defined by the structure of the O-polysaccharide chain (O-antigen) of the LPS. Until now, 76 O-serogroups have been differentiated among Proteus strains.

Structure of a new ribitol teichoic acid-like O-polysaccharide of a serologically separate Proteus vulgaris strain, TG 276-1, classified into a new Proteus serogroup O53.

An unusual ribitol teichoic acid-like O-polysaccharide was isolated by mild acid degradation of the lipopolysaccharide from a previously non-classified Proteus vulgaris strain TG 276-1. Structural studies using chemical analyses and 2D (1)H and (13)C NMR spectroscopy showed that the polysaccharide is a zwitterionic polymer with a repeating unit containing 2-acetamido-4-amino-2,4,6-trideoxy-D-galactose (D-FucNAc4N) and two D-ribitol phosphate (D-Rib-ol-5-P) residues and having the following structure:[formula: see text] where the non-glycosylated ribitol residue is randomly mono-O-acetylated. Based on the unique O-polysaccharide structure and the finding that the strain studied is serologically separate among Proteus bacteria, we propose to classify P.

Serological classification and epitope specificity of Proteus vulgaris TG 251 from Proteus serogroup O65.

Introduction: Proteus rods are currently subdivided into five named species, i.e. Proteus mirabilis, P.

Classification of Proteus mirabilis TG 115 and CCUG 10701 into the Proteus O23 serogroup based on chemical and serological studies of O-polysaccharides.

Introduction: Bacteria of the genus Proteus are a common cause of urinary tract infections. The O-polysaccharide (OPS) chain of their lipopolysaccharide (LPS) defines the serological specificity of strains. Based on the OPS structures and the immunospecificity of the LPS, Proteus strains have been classified into 74 O-serogroups.
