Fucosylation and sialylation of N-linked glycoprotein glycans are affected by LoDIR and a subset of N-glycans are involved in the organismal radio-response.

This is the first indication that the glycome can be interrogated for biomarkers that report the impact of chronic exposure to environmental stressors, such as low-level IR.

The efficiency of the bioherbicide was tested for the post-emergence control of Bidens pilosa L., Amaranthus viridis L., Echinochloa crusgalli (L.) Beauv., and Lolium multiflorum Lam. In the first step, different additives were used and lactose was the most suitable one because it resulted in high herbicidal activity and weed suppression. In the second step, process variables were investigated, including inlet air temperature, drying air flow rate, and feed flow rate. The highest herbicidal activity was obtained with an inlet air temperature of 100°C, and air and feed flow rates of 1.4 m3/min and 0.22 L/h, respectively. Maximum herbicidal activities were 38, 45, 21 and 18%, while weed heights reduction were 69.0, 74.3, 20.4 and 24.8% for B. find more pilosa, A. viridis, E. crusgalli and L. multiflorum, respectively. The bioherbicide was effective to suppress weed growth and spray drying is a promising technology for the production of solid formulations of bioherbicides.The use of electronic cigarettes (e-cigarettes) has been rising among adolescents and adults in the United States, including among Asian Americans. However, despite being one of the largest racial/ethnic minority groups, the specific trends and patterns of e-cigarette use among Asian Americans are understudied and unclear. This review aimed to summarize relevant information in the last two decades. This systematic review followed the a priori guide outlined by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Articles were gathered from PsycINFO, PubMed, Sage Journals Online, ScienceDirect, and SpringerLink. Forty articles were reviewed and analyzed. Most articles reviewed only reported on the prevalence rate of e-cigarettes among Asian Americans and indicated regional differences. Results noted between- and within-group differences among racial/ethnic groups that warrant further examination. There is a dearth of information regarding health outcomes and correlates or predictors of e-cigarette use among Asian Americans. Despite its popularity and prevalence among Asian Americans, the use of e-cigarettes and related factors or outcomes deserves more nuanced studies and analyses. It is important to delineate subgroup differences by adjusting study designs and data analytic methods to glean meaningful information regarding Asian American's e-cigarette use in the future.Bioremediation is an important function of microorganisms in relation to contaminated soils, wastewater and effluent. Microbes have always been demonstrated to be cost-efficient in the treatment of industrial effluents containing heavy metals like chromium(VI). As more and more new and novel isolates are being discovered with having the ability to acclimatize to varying environments. The application of microorganisms, especially that of bacteria, proves to be showing a greater potential as a low costing biotechnological application. The procedure can be adjusted according to the needs and conditional requirements where the bio-absorbents utilized might be either dead or living. Microbial bioabsorption of chromium(VI) stands out to be an alternative for the removal of the toxic contaminant. This review is focused on the different biosorbent features appropriate in the removal of chromium; different types of bioreactors; and the evolution of research with an overview of bioabsorption.In the view of many, heritable human genome editing (HHGE) harbors the remedial potential of ridding the world of deadly genetic diseases. A Hippocratic obligation, if there ever was one, HHGE is widely viewed as a life-sustaining proposition. The national go/no-go decision regarding the implementation of HHGE, however, must not, in the collective view of the authors, proceed absent thorough public engagement. A comparable call for an "extensive societal dialogue" was recently issued by the International Commission on the Clinical Use of Human Germline Genome Editing. In this communication, the authors lay out the foundational principles undergirding the formation, modification, and evaluation of public opinion. It is against this backdrop that the societal decision to warrant or enjoin the clinical conduct of HHGE will doubtlessly transpire.CRISPR-Cas systems have become ubiquitous for genome editing in eukaryotic as well as bacterial systems. Cas9 forms a complex with a guide RNA (gRNA) and searches DNA for a matching sequence (target site) next to a protospacer adjacent motif (PAM). Once found, Cas9 cuts the DNA. Cas9 is revolutionary for the ability to change the RNA sequence and target a new site easily. However, while algorithms have been developed to predict gRNA-specific Cas9 activity, a fundamental biological understanding of gRNA-specific activity is lacking. The number of PAM sites in the genome is effectively a large pool of inhibitory substrates, competing with the target site for the Cas9/gRNA complex. We demonstrate that increasing the number of non-target sites for a given gRNA reduces on-target activity in a dose-dependent manner. Furthermore, we show that the use of Cas9 mutants with increased PAM specificity toward a smaller subset of PAMs (or smaller pool of competitive substrates) improves cutting rates, while increased PAM promiscuity decreases cutting rates. Decreasing the potential search space by increasing PAM specificity provides a path toward improving on-target activity for slower high-fidelity Cas9 variants. Engineering improved PAM specificity to reduce the competitive search space offers an alternative strategy to engineer Cas9 variants with increased specificity and maintained on-target activity.
