Dealing with Food Insecurity, on a Longer Term
Longer term investments are needed to enable the over 500 million small holder farmers in developing countries to grow more food, thus increasing their incomes and resilience. Credit: Miriam Gahtigah/IPS By Esther NgumbiILLINOIS, United States, Jul 16 2020 (IPS) African countries are beginning to reopen borders, and this is finally enabling many citizens to resume their normal life. However, there is still an urgent need for African countries to prioritize agriculture to tackle food insecurity issues that have been exacerbated by COVID and will continue to be an issue into the near future. According to the latest estimates...

The Transcriptome of the Salivary Glands of Amblyomma aureolatum Reveals the Antimicrobial Peptide Microplusin as an Important Factor for the Tick Protection Against Rickettsia rickettsii Infection
Conclusion In conclusion, our data show that R. rickettsii exerts a modulatory effect on the transcriptional profile the SG of A. aureolatum. Moreover, RNAi experiments demonstrated that the knockdown of one microplusin increases the susceptibility of ticks to infection, suggesting that this is one important factor for the control of R. rickettsii. The functional characterization of the additional CDSs modulated by infection is warranted and might reveal other factors that interfere with the acquisition and/or transmission of this tick-borne pathogen. Ethics Statement All procedures involving vertebrate animals were car...

Docosahexaenoic Acid Increases the Potency of Soluble Epoxide Hydrolase Inhibitor in Alleviating Streptozotocin-Induced Alzheimer ’s Disease-Like Complications of Diabetes
Conclusion In the present study, we demonstrated that sEHI alleviates cognitive and memory impairment associated with diabetes-induced Alzheimer-like complication. The positive effect of sEHI TPPU on memory was associated with a reduction in oxidative stress and inflammation in the brain with a parallel decrease in the mRNA level of APP and activity of AChE. The DHA potentiated the effect of TPPU. Edaravone at a higher dose also alleviated memory impairment via decreasing oxidative stress and inflammation. Author Contributions RP, MA, SA, ML, and SG planned the experiments. RP, NB, KG, MA, and SA performed the experimen...

Expanding Research Capacity in Sub-Saharan Africa Through Informatics, Bioinformatics, and Data Science Training Programs in Mali
Conclusion Bioinformatics and data science training programs in developing countries necessitate incremental and collaborative strategies for their feasible and sustainable development. The progress described here covered decades of collaborative efforts centered on training and research on computationally intensive topics. These efforts laid the groundwork and platforms conducive for hosting a bioinformatics and data science training program in Mali. Training programs are perhaps best facilitated through Africa’s university systems as they are perhaps best positioned to maintain core resources during lapses in sho...

Characterization of α-Glucosidases From Lutzomyia longipalpis Reveals Independent Hydrolysis Systems for Plant or Blood Sugars
In this report, the authors consider that transglycosylation might be an adaptation for the obtention of monosaccharides from sucrose without the increase in osmolarity, as a simple hydrolytic reaction of a 0.7 M sucrose solution (phloem concentration) might result in osmotic shock for the midgut epithelial cells. In this respect, L. longipalpis enzymes might have the same biochemical adaptation. It would be very interesting to observe if this is a common trait of α-glucosidase from insects feeding on nectar or phloem sap, and verify if this is a case of evolutionary divergence or convergence. Two main mechanisms o...

Donnelly, Philip J. Rosenthal, Chris Drakeley, Steve W. Lindsay, Sarah G. Staedke, David L. Smith, Bryan Greenhouse, Moses R. Kamya, Grant Dorsey BackgroundLong-lasting insecticidal nets (LLINs) and indoor residual spraying of insecticide (IRS) are the primary vector control interventions used to prevent malaria in Africa. Although both interventions are effective in some settings, high-quality evidence is rarel...

Forensic Entomology: Evaluating Uncertainty Associated With Postmortem Interval (PMI) Estimates With Ecological Models
Estimates of insect age can be informative in death investigations and, when certain assumptions are met, can be useful for estimating the postmortem interval (PMI). Currently, the accuracy and precision of PMI estimates is unknown, as error can arise from sources of variation such as measurement error, environmental variation, or genetic variation. Ecological models are an abstract, mathematical representation of an ecological system that can make predictions about the dynamics of the real system. To quantify the variation associated with the pre-appearance interval (PAI), we developed an ecological model that simulates t...

This Is What Happens After You Die
(Photo: © Lightning + Kinglyface and Jess Bonham) Most of us would rather not think about what happens to our bodies after death. But that breakdown gives birth to new life in unexpected ways, writes Moheb Costandi.“It might take a little bit of force to break this up,” says mortician Holly Williams, lifting John’s arm and gently bending it at the fingers, elbow and wrist. “Usually, the fresher a body is, the easier it is for me to work on.”Williams speaks softly and has a happy-go-lucky demeanor that belies the nature of her work. Raised and now employed at a family-run funeral home in north Texas, she has s...
