    Abstract Monoclonal antibodies are an effective and growing class of pharmaceuticals for the treatment and prevention of a broad range of non-communicable and infectious diseases; however, most low- and middle-income countries have limited access to these innovative products. Many factors contribute to the global inequity of access to these products; however, in this report, we focus on clinical and regulatory complexities as further highlighted by the coronavirus disease 2019 pandemic. Despite a higher prevalence of many diseases in low- and middle-income countries, only 12% of clinical trials for monoclonal antibodies are conducted in these countries. Additionally, only a fraction of the available monoclonal antibodies in the USA and European Union are authorized for use in low- and middle-income countries. Through learnings from desk research and global symposia with international partners, we present recommendations to harmonize processes and facilitate regional and international collaborations for more rapid approval of fit-for-purpose innovative monoclonal antibodies and biosimilars in low- and middle-income countries.

    Abstract Beneficial microorganisms and plant essential oils are key components of sustainable agriculture, but knowledge of their compatibility is limited. We investigated the effect of 23 essential oils on three beneficial bacterial species (Bacillus cereus, Bacillus velezensis and Priestia megaterium) that are commercially used as biostimulants and biocontrol antagonists. Essential oils were tested at a dilution of 1:10, the highest economical use rate anticipated in crop protection applications. Seventeen of the 23 essential oils had no inhibitory activity against any of the three bacterial species. Onion essential oil had strong activity against B. velezensis and no activity against B. cereus or P. megaterium. Palmarosa and pimenta essential oils were active against B. velezensis and inactive against B. cereus and P. megaterium. Coriander essential oil was inactive against B. velezensis, active against B. cereus, and strongly active against P. megaterium. Oregano essential oil was active against the three bacterial species while garlic essential oil was active against B. cereus and strongly active against B. velezensis and P. megaterium. Allyl disulfide, carvacrol, eugenol, and geraniol, the major constituents of garlic, oregano, pimenta leaf, and palmarosa/coriander essential oils, respectively were active

    Abstract Lipid microdomains, ordered membrane phases containing cholesterol and glycosphingolipids, play an essential role in cancer cell adhesion and ultimately metastasis. Notably, elevated levels of cholesterol-rich lipid microdomains are found in cancer cells relative to their normal counterparts. Therefore, alterations of lipid microdomains through cholesterol modulation could be used as a strategy to prevent cancer metastasis. In this study, methyl-beta-cyclodextrin (MβCD), sphingomyelinase (SMase), and simvastatin (Simva) were used to investigate the effects of cholesterol on the adhesive behaviors of four non-small cell lung cancer (NSCLC) cell lines (H1299, H23, H460, and A549) and a small cell lung cancer (SCLC) cell line (SHP-77) on E-selectin, a vascular endothelial molecule that initiates circulating tumor cell recruitment at metastatic sites. Under hemodynamic flow conditions, the number of adherent NSCLC cells on E-selectin significantly decreased by MβCD and Simva treatments, whereas SMase treatment did not show a significant effect. Significant increases in rolling velocities were detected only for H1299 and H23 cells after MβCD treatment. In contrast, cholesterol depletion did not affect SCLC cell attachment and rolling velocities. Moreover, cholesterol depletion by MβCD and Simva induced CD44 shedding and resulted in an enhanced membrane fluidity in the NSCLC cells, whereas it did not affect the membrane fluidity of the SCLC cells which lacked detectable expression of CD44. Our finding suggests that cholesterol regulates the E-selectin-mediated adhesion of NSCLC cells by redistributing the CD44 glycoprotein and thus modulating the membrane fluidity.

    Abstract Strategic, sustainable, and ecofriendly alternatives to chemical pesticides are needed to effectively control mosquitoes and reduce the incidence of their vectored diseases. We evaluated several Brassicaceae (mustard family) seed meals as sources of plant derived isothiocyanates produced from the enzymatic hydrolysis of biologically inactive glucosinolates for the control of Aedes aegypti (L., 1762). Five defatted seed meals (Brassica juncea (L) Czern., 1859, Lepidium sativum L., 1753, Sinapis alba L., 1753, Thlaspi arvense L., 1753, and Thlaspi arvense-heat inactivated and three major chemical products of enzymatic degradation (allyl isothiocyanate, benzyl isothiocyanate and 4-hydroxybenzyl isothiocyanate) were assayed to determine toxicity (LC

    Abstract Tracking livestock abortion patterns over time and across factors such as species and agroecological zones (AEZs) could inform policies to mitigate disease emergence, zoonoses risk, and reproductive losses. We conducted a year-long population-based active surveillance of livestock abortion between 2019 and 2020, in administrative areas covering 52% of Kenya's landmass and home to 50% of Kenya's livestock. Surveillance sites were randomly selected to represent all AEZs in the country. Local animal health practitioners electronically transmitted weekly abortion reports from each ward, the smallest administrative unit, to a central server, using a simple short messaging service (SMS). Data were analyzed descriptively by administrative unit, species, and AEZ to reveal spatiotemporal patterns and relationships with rainfall and temperature. Of 23,766 abortions reported in all livestock species, sheep and goats contributed 77%, with goats alone contributing 53%. Seventy-seven per cent (n = 18,280) of these abortions occurred in arid and semi-arid lands (ASALs) that primarily practice pastoralism production systems. While spatiotemporal clustering of cases was observed in May-July 2019 in the ASALs, there was a substantial seasonal fluctuation across AEZs. Kenya experiences high livestock abortion rates, most of which go unreported. We recommend further research to document the national true burden of abortions. In ASALs, studies linking pathogen, climate, and environmental surveillance are needed to assign livestock abortions to infectious or non-infectious aetiologies and conducting human acute febrile illnesses surveillance to detect any links with the abortions.

    Abstract Cardiovascular disease (CVD, i.e., disease of the heart and blood vessels) is a major cause of death globally. Current assessment tools use either clinical or non-clinical factors alone or in combination to assess CVD risk. The aim of this review was to critically appraise, compare, and summarize existing non-clinically based tools for assessing CVD risk factors in underserved young adult (18-34-year-old) populations. Two online electronic databases-PubMed and Scopus-were searched to identify existing risk assessment tools, using a combination of CVD-related keywords. The search was limited to articles available in English only and published between January 2008 and January 2019. Of the 10,383 studies initially identified, 67 were eligible. In total, 5 out of the 67 articles assessed CVD risk in underserved young adult populations. A total of 21 distinct CVD risk assessment tools were identified; six of these did not require clinical or laboratory data in their estimation (i.e., non-clinical). The main non-clinically based tools identified were the Heart Disease Fact Questionnaire, the Health Beliefs Related to CVD-Perception measure, the Healthy Eating Opinion Survey, the Perception of Risk of Heart Disease Scale, and the WHO STEPwise approach to chronic disease factor surveillance (i.e., the STEPS instrument).
