Light is an important environmental signal for most insects. The Oriental Armyworm, Mythimna separata, is a serious pest of cereal crops worldwide, and is highly sensitive to light signals during its developmental and reproductive stages. However, molecular biological studies of its response to light stress are scarce, and related genomic information is not available. In this study, we sequenced and de novo assembled the transcriptomes of M. separata exposed to four different light conditions: dark, white light (WL), UV light (UVL) and yellow light (YL)...

Silver nanoparticles (AgNPs) of different shapes and sizes were prepared by solution-based chemical reduction routes. Silver nitrate was used as a precursor, tri-sodium citrate (TSC) and sodium borohydride as reducing agents, while polyvinylpyrrolidone (PVP) was used as a stabilizing agent. The morphology, size, and structural properties of obtained nanoparticles were characterized by scanning electron microscopy (SEM), UV-visible spectroscopy (UV-VIS), and X-ray diffraction (XRD) techniques. Spherical AgNPs, as depicted by SEM, were found to have diameters in the range of 15 to 90 nm while lengths of the edges of the triangular particles were about 150 nm...

BACKGROUND: Statins are one of the most common medications for stroke prevention. Increasing evidence indicates that the effect of statins against stroke may depend on the optimal adherence of the patients to the long-term therapies. However, the magnitude of the association between statin adherence and the risk of stroke has not been determined. OBJECTIVE: We conducted a dose-response meta-analysis to investigate the association between statin adherence and the risk of stroke...

BACKGROUND: Various strategies are implemented to increase blood safety. However, there is always a small amount of residual risk. The amount of risk is associated with the incidence and prevalence of infection in the community. Since increases in the prevalence and changing the pattern of HIV transmission have been observed in the community, monitoring of HIV prevalence among general population and blood donors is necessary. This study aimed to determine the prevalence of HIV in Iranian blood donations...

Vitamin B12 plays an essential role in fetal and infant development. In regions where animal source food consumption is low and perinatal supplementation is uncommon, infants are at risk of vitamin B12 deficiency. In this secondary analysis, we measured total vitamin B12 concentrations in maternal and infant serum/plasma and breast milk among two samples of mother-infant dyads in Canada (assessed at 8 weeks post-partum) and in Cambodia (assessed between 3-27 weeks post-partum). Canadian mothers (n = 124) consumed a daily vitamin B12-containing multiple micronutrient supplement throughout pregnancy and lactation; Cambodian mothers (n = 69) were unsupplemented...
