The migratory fall armyworm, Spodoptera frugiperda (Smith), has become a worldwide agricultural pest. In this study, the effects of photoregime on the development, reproduction, and flight performance of fall armyworm were assessed based on two-sex life tables, ovarian and testis anatomy, and flight mill tests. The results indicated that photoregime had a significant effect on developmental duration of fall armyworm individuals, pupal survival and emergence, and adult fecundity. Among seven photoregimes tested, the 168 (LD) h photoregime was the most suitable for fall armyworm fitness with the shortest pre-oviposition period and mean generation period (T), highest mating frequency and mating rate of female moths, largest intrinsic rate of natural increase (rm) and finite rate of increase (λ), and highest net reproduction rate (R0). Population growth for seven different photoregimes in decreasing order was 168 (LD) h > 816 (LD) h > 1212 (LD) h > 1014 (LD) h > 1410 (LD) h > 024 (LD) h > 240 (LD) h. The ovarian development level, mating frequency, and testis size did not significantly differ between long (168 (LD) h) and short (1014 (LD) h) illumination. Photoregime had a significant effect on mass loss during flight of adults, but not on flight velocity, flight duration, and flight distance. These findings can be used to refine laboratory rearing protocols, accurately predict seasonal changes in population dynamics and should help improve regional forecasts and management of the fall armyworm.Viruses are responsible for causing various epidemics and pandemics with a high mortality rate e.g. ongoing SARS-CoronaVirus-2 crisis. The discovery of novel antivirals remains a challenge but drug repurposing is emerging as a potential solution to develop antivirals in a cost-effective manner. In this regard, we collated the information of repurposed drugs tested for antiviral activity from literature and presented it in the form of a user-friendly web server named 'DrugRepV'. The database contains 8485 entries (3448 unique) with biological, chemical, clinical and structural information of 23 viruses responsible to cause epidemics/pandemics. The database harbors browse and search options to explore the repurposed drug entries. The data can be explored by some important fields like drugs, viruses, drug targets, clinical trials, assays, etc. For summarizing the data, we provide overall statistics of the repurposed candidates. To make the database more informative, it is hyperlinked to various external repositories like DrugBank, PubChem, NCBI-Taxonomy, Clinicaltrials.gov, World Health Organization and many more. 'DrugRepV' database (https//bioinfo.imtech.res.in/manojk/drugrepv/) would be highly useful to the research community working to develop antivirals.

To demonstrate a novel method for presenting and exploring data in systematic reviews of the alcohol literature.

Harvest plots are a graphical method for displaying data on the overall pattern of evidence from a systematic review. They can display the direction of effects and risk of bias within studies for multiple outcomes in a single graphical chart. Using data from our previous meta-analysis on the association between personality disorder and alcohol treatment outcome, we extended the application of harvest plots by developing an interactive online harvest plot application.

Studies included in the review were heterogeneous in design. There were many different primary outcomes, and similar outcomes were often defined differently across studies. The interactive harvest plot allows readers to explore trends in the data across multiple outcomes, including the impact of within-study bias and year of publication. In contrast, meta-analysis on the same data was hampered by a lack of consistency in the way outcomes were measured, and incomplete reporting of effect sizes and their variance. This meant many studies included in the systematic review could not be meta-analysed.

Interactive harvest plots are a novel graphical method to present data from systematic reviews. They can supplement or even replace meta-analysis when the studies included in a systematic review use heterogeneous designs and measures, as is often the case in the alcohol literature.

Despite conservation of the catalytic residues, this single Trp enzyme has an insertion sequence (-153ESEEKAWQKLCSL165-) that is extremely crucial to function. Immunology chemical This sequence contains the critical residues, which are conserved in the homolog of other Helicobacter gastric pathogens. However, the underlying basis for the role of this motif in catalytic function is not completely understood. Here, we used biochemical, biophysical and molecular dynamics simulations studies to determine that Glu155 of this stretch interacts with both Lys57 and Ser152. These interactions are essential for positioning of the motif through Trp159, which is located near Glu155 (His122-Trp159-Tyr125 contact is essential to tertiary structural integrity). The individual or double mutation of Lys57 and Ser152 to Ala considerably reduces catalytic activity with Lys57 to Ala being more significant, indicating they are crucial to function. Our data suggest that the Lys57-Glu155-Ser152 interaction influences the positioning of the loop containing the catalytic His133 so that this His can participate in catalysis, thereby providing a mechanistic understanding into the role of this motif in catalytic function. Lys57 was also found only in the arginases of other Helicobacter gastric pathogens. Based on the non-conserved motif, we found a new molecule, which specifically inhibits this enzyme. Thus, the present study not only provides a molecular basis into the role of this motif in function, but also offers an opportunity for the design of inhibitors with greater efficacy.
