ObjectiveThe current study examined whether bullying victimization was associated with bringing a weapon to school, fully or partly mediated by feeling unsafe in school, negative future education orientation, and skipping school.MethodData from 6199 students (12–18 years old), who had filled out the 2017 School Crime Supplement to the National Crime Victimization Survey, were analyzed.ResultsThe r

Background In the early 1980s, a preservative containing a mixture of methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) in a ratio of 3:1 was introduced. This mixture (mix) has been patch tested at 100 ppm (0.01%) worldwide and at 200 ppm (0.02%) in Sweden since 1986 and also in the European baseline series since 2014. Objective A new aqueous mix of MCI 0.015% and MI 0.2% was compar

This paper proposes Yggdrasil, a protocol for privacy-aware dual data deduplication in multi-client settings. Yggdrasil is designed to reduce cloud storage space while safeguarding the privacy of clients’ data. This is achieved by exploiting a ‘dual’ setting, where both the cloud and the clients store a fraction of the data. Yggdrasil combines two innovative techniques to achieve this goal. First,

SBI-0206965, originally identified as an inhibitor of the autophagy initiator kinase ULK1, has recently been reported as a more potent and selective AMP-activated protein kinase (AMPK) inhibitor relative to the widely used, but promiscuous inhibitor Compound C/ Dorsomorphin. Here, we studied the effects of SBI-0206965 on AMPK signalling and metabolic readouts in multiple cell types, including hepa

The cfr gene encodes the Cfr methyltransferase that primarily methylates C-8 in A2503 of 23S rRNA in the peptidyl transferase region of bacterial ribosomes. The methylation provides resistance to six classes of antibiotics of clinical and veterinary importance. The rlmN gene encodes the RlmN methyltransferase that methylates C-2 in A2503 in 23S rRNA and A37 in tRNA, but RlmN does not significantly

Aims: The HERMES (HEart failure Molecular Epidemiology for Therapeutic targetS) consortium aims to identify the genomic and molecular basis of heart failure. Methods and results: The consortium currently includes 51 studies from 11 countries, including 68 157 heart failure cases and 949 888 controls, with data on heart failure events and prognosis. All studies collected biological samples and perf

The wheel-rail system operates in an open environment where the weather condition varies constantly. In this laboratory study, an investigation using a pin-on-disc tribometer placed in a temperature-controlled room was conducted to examine the effect of subzero temperature and snow on friction and wear at the wheel-rail contact. In temperature range from 3 to-15 °C (without snow) friction and wear

Deciphering the genotype–phenotype map necessitates relating variation at the genetic level to variation at the phenotypic level. This endeavour is inherently limited by the availability of standing genetic variation, the rate of spontaneous mutation to novo genetic variants, and possible biases associated with induced mutagenesis. An interesting alternative is to instead rely on the environment a

The Caenorhabditis elegans (C. elegans) germline is used to study several biologically important processes including stem cell development, apoptosis, and chromosome dynamics. While the germline is an excellent model, the analysis is often two dimensional due to the time and labor required for three-dimensional analysis. Major readouts in such studies are the number/position of nuclei and protein

The study aims to understand the influence of environmental and lifestyle factors and more specifically the role of tobacco smoke–infused water (tuibur) on Helicobacter pylori infection. It was a cross-sectional study to measure the epidemiological risk factors associated with H. pylori infection among the tribal population in Northeast India. Endoscopic samples were collected from the antrum regi

Stingless bees are important pollinators in the tropics. The tremendous variation in body size makes them an excellent group to study how miniaturization affects vision and visual behaviours. Using direct measurements and micro-CT, we reconstructed the eye structure, estimated anatomical spatial resolution and optical sensitivity of the stingless bee Tetragonula iridipennis. T. iridipennis is simi

The diversity of bacteriophages is likely unparalleled in the biome due to the immense variety of hosts and the multitude of viruses that infect them. Recent efforts have led to description at the genomic level of numerous bacteriophages that infect the Actinobacteria, but relatively little is known about those infecting other prokaryotic phyla, such as the purple non-sulfur photosynthetic α-prote

This study follows on from a network-based assessment redesign project at a Canadian university, to investigate factors relating to academic engagement and sustained implementation. The project was designed with mini-grants, embedded support and a community of practice. Assessment facilitators worked in discipline clusters to achieve mutual goals for assessment reform targeted at authentic develo

We study the impact of the early gender environment on inequality in the labor market. To this end, we link primary school data to occupations and earnings. We find that women exposed to more girls at critical ages earn more later on: A 10 percent increase in the share of girls leads to a gender wage gap reduction of 2.7 percent. We explore mechanisms and find a strong selection of women into less
