Alpha-1-acid glycoprotein (AGP) is an acute phase glycoprotein in blood, which is primarily synthetized in the liver and whose biological role is not completely understood. It consists of 45% carbohydrates that are present in the form of five N-linked complex glycans. AGP N-glycosylation was shown to be changed in many different diseases and some changes appear to be disease-specific, thus it has a great diagnostic and prognostic potential. However, AGP glycosylation was mainly analyzed in small cohorts and without detailed site-specific glycan information. Here, we developed a cost-effective method for a high-throughput and site-specific N-glycosylation LC-MS analysis of AGP which can be applied on large cohorts, aid in search for novel disease biomarkers and enable better understanding of AGP’s role and function in health and disease. The method does not require isolation of AGP with antibodies and affinity chromatography, but AGP is enriched by acid precipitation from 5 μl of bloodplasma in a 96 well format. After trypsinization, AGP glycopeptides are purified using a hydrophilic interaction chromatography based solid-phase extraction and analyzed by RP-LC-ESI-MS. We used our method to show for the first time that AGP N-glycan profile is stable in healthy individuals (14 individuals in 3 time points), which is a requirement for evaluation of its diagnostic potential. Furthermore, we tested our method on a population including individuals with registered hyperglycemia in critical illness (59 cases and 49 controls), which represents a significantly increased risk of developing type 2 diabetes. Individuals at higher risk of diabetes presented increased N-glycan branching on AGP’s second glycosylation site and lower sialylation of N-glycans on AGP’s third and AGP1’s fourth glycosylation site. Although this should be confirmed on a larger prospective cohort, it indicates that site-specific AGP N-glycan profile could help distinguish individuals who are at risk of type 2 diabetes.

Giardia lamblia (G. lamblia) disease is a zoonosis with a-infection rate affecting the general population of the world. Despite the constant possibility of damage due to their own metabolism, G. lamblia have survived and evolved to adapt to various environments. However, research on energy-metabolism conversion in G. lamblia is limited. This study aimed to reveal the dynamic metabolism-conversion mechanism in G. lamblia under sugar starvation by detecting global lysine acetylation and 2-hydroxyisobutyrylation sites combined with quantitative proteome analyses. A total of 2999 acetylation sites on 956 proteins and 8877 2-hydroxyisobutyryl sites on 1546 proteins were quantified under sugar starvation. Integrated Kac and Khib data revealed that modified proteins were associated with arginine biosynthesis, glycolysis/gluconeogenesis, and alanine, aspartate, and glutamate metabolism. These findings suggested that lysine acetylation and 2-hydroxyisobutyrylation were ubiquitous and provided deep insight into the metabolism-conversion mechanism in G. lamblia under sugar starvation. Overall, these results can help understand the biology of G. lamblia infections and reveal the evolution rule from prokaryote to eukaryote.

Recent advances in MS-based proteomics have vastly increased the quality and scope of biological information that can be derived from human samples. These advances have rendered current workflows increasingly applicable in biomedical and clinical contexts. As proteomics is poised to take an important role in the clinic, associated ethical responsibilities increase in tandem with the impact on the health, privacy, and well-being of individuals. Here we conducted and report a systematic literature review of ethical issues in clinical proteomics. We add our perspectives from a background of bioethics, the results of our accompanying paper extracting individual-sensitive results from patient samples, and the literature addressing similar issues in genomics. The spectrum of potential issues ranges from patient re-identification to incidental findings of clinical significance. The latter can be divided into actionable and unactionable findings. Some of these have the potential to be employed in discriminatory or privacy-infringing ways. However, incidental findings may also have great positive potential. A plasma proteome profile, for instance, could inform on the general health or disease status of an individual regardless of the narrow diagnostic question that prompted it. We suggest that early discussion of ethical issues in clinical proteomics is important to ensure that eventual regulations reflect the considered judgment of the community as well as to anticipate opportunities and problems that may arise as the technology matures further.

Centenary Series: Exploring the International Affairs Archive dora.popova 14 September 2020

International Affairs has been a central part of the institute’s history, both as a record of speeches made by dignitaries such as Mahatma Gandhi and Henry Kissinger, and as a forum for policy-relevant academic research.

Delving into the International Affairs archive brings out stories behind some of the most significant players of the last century.

New research on 21st-century conflict 25 April 2022 — 5:00PM TO 6:00PM Anonymous (not verified) 11 April 2022 Online

This International Affairs webinar shares research on US special operations, urban warfare, and digital activism in recent conflicts.

Given the ongoing Russian invasion of Ukraine, and continuing conflicts in Myanmar, Yemen, and other countries, it is important to understand the changing nature of conflict in the 21st century.

In this webinar, authors from the March 2022 issue of International Affairs share research on the transformation of Western special forces, the impact of army size in urban warfare, and the use of social media and online activism in war.

The speakers in this event drew on the following research:

• US Special Forces transformation: post-Fordism and the limits of networked warfare (https://doi.org/10.1093/ia/iiab213)
• Urban insurgency in the twenty-first century: smaller militaries and increased conflict in cities (https://doi.org/10.1093/ia/iiac007)
• Diasporas as cyberwarriors: infopolitics, participatory warfare and the 2020 Karabakh war (https://doi.org/10.1093/ia/iiac015)

International Affairs was started at Chatham House in 1922 to communicate research to members who could not attend in person. Over the past 100 years, it has transformed into a journal that publishes academically rigorous and policy-relevant research. It is published for Chatham House by Oxford University Press.

Background: Faced with the limits of synthetic antipyretic substances, in particular their involvement in the occurrence of numerous and often serious adverse effects; the challenge is in search of new antipyretics especially from the African traditional pharmacopoeia. The objective of this study was to evaluate the antipyretic activity of an aqueous extract and a formulation of Ceiba pentandra, with a view to designing an herbal antipyretic drug. Methods: Trials of formulation of an antipyretic syrup with leaves extract of Ceiba pentandra were carried out. The antipyretic activity was investigated by the bewer's yeast induced pyrexia. Physicochemical and microbiological stability tests were carried out on the syrup. Results: It was found with the extract an antipyretic activity at doses of 125 mg/kg and 150 mg/kg. The effect was greater for the 125 mg/kg dose with inhibition percentages ranging from 27.58% to 71.25%. This antipyretic activity was early (from 30 minutes) and was preserved during the four hours of the experiment. The syrup dosed at 125 mg/kg gave an activity similar to that of the extract by significantly reducing the hyperthermia in the rats. Regarding the stability tests, the syrup remained stable both physico-chemically and microbiologically throughout the study period (28 days) both when exposed to low temperature (5 °±3 ° C) and at high temperature (40°±2° C). Conclusions: Ceiba pentandra leaves have antipyretic activity and could be used for the development of an herbal antipyretic drug.
