Data on the association between obesogenic behaviours and bullying victimization among adolescents are scarce from low- and middle-income countries.

To assess the associations between obesogenic behaviours and bullying victimization in 54 low- and middle-income countries.

Cross-sectional data from the global school-based student health survey were analyzed. Data on bullying victimization and obesogenic behaviours were collected. The association between bullying victimization and the different types of obesogenic behaviour (anxiety-induced insomnia, fast-food consumption, carbonated soft-drink consumption, no physical activity and sedentary behaviour) were assessed by country-wise multivariable logistic regression analysis adjusting for age, sex, food insecurity and obesity with obesogenic behaviours being the outcome.

The sample consisted of 153 929 students aged 12 to 15 years [mean (SD) age 13.8 (1.0) years; 49.3% girls]. Overall, bullying victimization (vs no bullying victimization) was significantly associated with greater odds for all types of obesogenic behaviour with the exception of physical activity, which showed an inverse association. Specifically, the ORs (95% CIs) were anxiety-induced sleep problems 2.65 (2.43-2.88); fast-food consumption 1.36 (1.27-1.44); carbonated soft-drink consumption 1.14 (1.08-1.21); no physical activity 0.84 (0.79-0.89); and sedentary behaviour 1.34 (1.25-1.43).

In this large representative sample of adolescents from low- and middle-income countries, bullying victimization was found to be associated with several, but not all, obesogenic behaviours.

Due to their similar polarity, it is difficult to select a suitable solvent system for one-step separation. CPI-613 cell line Three fractions including one pure compound were only obtained with a relatively suitable solvent system of ethyl acetate n-butanolwater (0.5% glacial acetic acid) (4610, vvv). In order to improve the separation efficiency, recycling and heart cut modes were introduced. As a result, two flavonoids with separation factor value at 1.13 and the other two with separation factor value at 1.20 were successfully separated. Finally, five flavonoids with purity higher than 98% were obtained. Fortunately, a new compound named myricetin 3'-methyl ether 3-O-glucoside-7-O-rhamnoside was obtained. The results indicated that the recycling combined with heart-cut mode could be effective for the preparation of natural compounds with similar polarity.The emergence of atomically precise metal nanoclusters with unique electronic structures provides access to currently inaccessible catalytic challenges at the single-electron level. We investigate the catalytic behavior of gold Au25 (SR)18 nanoclusters by monitoring an incoming and outgoing free valence electron of Au 6s1 . Distinct performances are revealed Au25 (SR)18- is generated upon donation of an electron to neutral Au25 (SR)180 and this is associated with a loss in reactivity, whereas Au25 (SR)18+ is generated from dislodgment of an electron from neutral Au25 (SR)180 with a loss in stability. The reactivity diversity of the three Au25 (SR)18 clusters stems from different affinities with reactants and the extent of intramolecular charge migration during the reactions, which are closely associated with the valence occupancies of the clusters varied by one electron. The stability difference in the three clusters is attributed to their different equilibria, which are established between the AuSR dissociation and polymerization influenced by one electron.Cytosine plays a preeminent role in DNA methylation, an epigenetic mechanism that regulates gene expression, the misregulation of which can lead to severe diseases. Several methods are nowadays employed for assessing the global DNA methylation levels, but none of them combines simplicity, high sensitivity, and low operating costs to be translated into clinical applications. Ultraviolet (UV) resonant Raman measurements at excitation wavelengths of 272 nm, 260 nm, 250 nm, and 228 nm have been carried out on isolated deoxynucleoside triphosphates (dNTPs), on a dNTP mixture as well as on genomic DNA (gDNA) samples, commercial from salmon sperm and non-commercial from B16 murine melanoma cell line. The 228 nm excitation wavelength was identified as the most suitable energy for enhancing cytosine signals over the other DNA bases. The UV Raman measurements performed at this excitation wavelength on hyper-methylated and hypo-methylated DNA from Jurkat leukemic T-cell line have revealed significant spectral differences with respect to gDNA isolated from salmon sperm and mouse melanoma B16 cells. This demonstrates how the proper choice of the excitation wavelength, combined with optimized extraction protocols, makes UV Raman spectroscopy a suitable technique for highlighting the chemical modifications undergone by cytosine nucleotides in gDNA upon hyper- and hypo-methylation events.Vertebrates have evolved flexible and hard dermal armor, but there is often a tradeoff between mobility and protection. Skeletal modifications include fish scales, the shells of tortoises and turtles, and the cranial projections that are found in marine iguanas and lionfish. Sexual dimorphisms of cranial structures are prominent in fishes; we hypothesized that cranial projections of Pterois volitans will change over ontogeny and are sexually dimorphic. The goal of this study is to quantify differences in the cranial armor of P. volitans over a range of sizes (juveniles to adults) to understand allometric growth and possible sexual dimorphisms using specimens from invaded ranges. We found no difference in the total number of cranial spines between sexes, suggesting that the number of cranial spines is not a sexually dimorphic trait in P. volitans. We found positive allometry for total cranial spine number, and length and width of the three largest cranial spines, with respect to the fish total length. Here, we also document another skeletal modification in P.
