Publication date: Available online 19 September 2014 Source:International Journal for Parasitology: Drugs and Drug Resistance Author(s): Roopa Ramamoorthi , Katy M. Graef , Jennifer Dent Neglected tropical diseases (NTDs), malaria, and tuberculosis have a devastating effect on an estimated 1.6billion people worldwide. The World Intellectual Property Organization (WIPO) Re:Search consortium accelerates the development of new drugs, vaccines, and diagnostics for these diseases by connecting the assets and resources of pharmaceutical companies, such as compound libraries and expertise, to academic or nonprofit researchers w...

Pyrimidine Metabolism in Schistosomes: A comparison with Other Parasites and the Search for Potential Chemotherapeutic Targets.
Abstract Schistosomes are responsible for the parasitic disease schistosomiasis, an acute and chronic parasitic ailment that affects more than 240 million people in 70 countries worldwide. It is the second most devastating parasitic disease after malaria. At least 200,000 deaths per year are associated with the disease. In the absence of the availability of vaccines, chemotherapy is the main stay for combating schistosomiasis. The antischistosomal arsenal is currently limited to a single drug, Praziquantel, which is quite effective with a single-day treatment and virtually no host-toxicity. Recently, however, the ...

Studies on Activities and Chemical Characterization of Medicinal Plants in Search for New Antimalarials: A Ten Year Review on Ethnopharmacology
Malaria is an endemic disease that affected 229 million people and caused 409 thousand deaths, in 2019. Disease control is based on early diagnosis and specific treatment with antimalarial drugs since no effective vaccines are commercially available to prevent the disease. Drug chemotherapy has a strong historical link to the use of traditional plant infusions and other natural products in various cultures. The research based on such knowledge has yielded two drugs in medicine: the alkaloid quinine from Cinchona species, native in the Amazon highland rain forest in South America, and artemisinin from Artemisia annua, a spe...

Gauche(+) side-chain orientation as a key factor in the search for an immunogenic peptide mixture leading to a complete fully protective vaccine.
Abstract Topological and stereo-electron characteristics are essential in major histocompability class II-peptide-T-cell receptor (MHC-p-TCR) complex formation for inducing an appropriate immune response. Modified high activity binding peptides (mHABPs) were synthesised for complete full protection antimalarial vaccine development producing a large panel of individually fully protection-inducing protein structures (FPIPS) and very high long-lasting antibody-inducing (VHLLAI) mHABPs. Most of those which did not interfere, compete, inhibit or suppress their individual VHLLAI or FPIPS activity contained or displayed ...

From “Serum Sickness” to “Xenosialitis”: Past, Present, and Future Significance of the Non-human Sialic Acid Neu5Gc
Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human dis...

Philanthropists Join Forces to Fund Africa ’s Cash-Strapped Health Sector
Tristate Heart and Vascular Centre in Nigeria. Credit: Tristate Heart and Vascular CentreBy Pavithra Rao, Africa Renewal*NEW YORK, Sep 28 2017 (IPS)In the 2017 World Happiness Report by Gallup, African countries score poorly. Of the 150 countries on the list, the Central African Republic, Tanzania and Burundi rank as the unhappiest countries in the world. Some of the factors driving unhappiness are the poor state of the continent’s health care systems, the persistence of HIV/AIDS, malaria and tuberculosis, and the growth of lifestyle diseases such as hypertension, heart disease and diabetes.Few African countries make sig...

Capturing the Fantastic Voyage of Monocytes Through Time and Space
Conclusion and Future Perspectives Despite being described in many important studies in the last century, our comprehension of monocyte biology has only taken a substantial leap in the past decade upon the advent of highly sophisticated imaging techniques that complement the current use of biochemistry, cell biology and genetic tools. More importantly, 2P-IVM has unveiled critical trafficking mechanisms that may have important implications for future vaccine designs/therapeutic strategies. In particular, the specific kinetics of monocyte trafficking in different tissue compartments and their interaction with other immune ...

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...

Interventions for improving coverage of childhood immunisation in low- and middle-income countries.
CONCLUSIONS: Providing parents and other community members with information on immunisation, health education at facilities in combination with redesigned immunisation reminder cards, regular immunisation outreach with and without household incentives, home visits, and integration of immunisation with other services may improve childhood immunisation coverage in LMIC. Most of the evidence was of low certainty, which implies a high likelihood that the true effect of the interventions will be substantially different. There is thus a need for further well-conducted RCTs to assess the effects of interventions for improving chi...

The First Outbreak of Autochthonous Zika Virus in Sabah, Malaysian Borneo
Conclusions Surveillance, risk assessment, and intervention were strengthened throughout Malaysia in response to the 2016 outbreak of ZIKV in neighboring Singapore. The Malaysian Ministry of Health undertook regular surveillance from June 2015 during the South American outbreak, but no ZIKV was detected in 784 samples tested up to August 2016 (https://kpkesihatan.com/2016/08/28/kenyataan-akhbar-kpk-28-ogos-2016-situasi-terkini-virus-zika-di-malaysia/). However, during the peak of the 2016 Singapore ZIKV outbreak from September through December 2016, eight out of 849 samples tested were positive for ZIKV (https://kpkesiha...

Fight Aging! Newsletter, January 28th 2019
In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...
