The mRNA cap-binding protein, eIF4E, mediates the recognition of the mRNA 5' end and, as part of the heterotrimeric eIF4F complex, facilitates the recruitment of the ribosomal subunits to initiate eukaryotic translation. Various regulatory events involving eIF4E and a second eIF4F subunit, eIF4G, are required for proper control of translation initiation. In pathogenic trypanosomatids, six eIF4Es and five eIF4Gs have been described, several forming different eIF4F-like complexes with yet unresolved roles. EIF4E5 is one of the least known of the trypanosomatid eIF4Es and has not been characterized in Leishmania species. Here, we used immunoprecipitation assays, combined with mass-spectrometry, to identify major EIF4E5 interacting proteins in L. infantum. A constitutively expressed, HA-tagged, EIF4E5 co-precipitated mainly with EIF4G1 and binding partners previously described in Trypanosoma brucei, EIF4G1-IP, RBP43 and the 14-3-3 proteins. In contrast, no clear co-precipitation with EIF4G2, also previously reported, was observed. EIF4E5 also co-precipitated with protein kinases, possibly associated with cell-cycle regulation, selected RNA binding proteins and histones. Phosphorylated residues were identified and mapped to the Leishmania-specific C-terminal end. Mutagenesis of the tryptophan residue (W53) postulated to mediate interactions with protein partners or of a neighbouring tryptophan conserved in Leishmania (W45) did not substantially impair the identified interactions. Finally, the crystal structure of Leishmania EIF4E5 evidences remarkable differences in the eIF4G interfacing region, when compared with human eIF4E-1 and with its Trypanosoma orthologue. Mapping of its C-terminal end near the cap-binding site also imply relevant differences in cap-binding function and/or regulation.COVID-19 pandemic has affected the world, including developing countries in various aspects. This pandemic might have severe consequences in terms of population health, especially in places where the health system is already weak. Using the health facility-level data over time, we evaluated the impact of COVID-19 lockdown on the vaccination service delivery in Nigeria. The lockdown was announced on March 30, 2020 and was effective until May 4, 2020. Compared to the quantity of vaccinations administered in March 2020, the quantity was significantly reduced during April 2020. The quantity was further reduced during May 2020. However, from June onwards, the quantity of vaccination administered has recovered. We observed that, although the lockdown reduced the quantity of vaccination administered significantly, it quickly recovered soon after the lockdown was relaxed.Detention and removal of unauthorised immigrants by United States (U.S.) Immigration and Customs Enforcement (ICE) has steadily increased despite declining rates of unauthorised migration. ICE detainees are held in overcrowded detention centres, often without due process and deprived of adequate food, sanitation, and medical care. Conditions of ICE detention contribute to malnutrition and increase the likelihood of infectious disease exposure, including tuberculosis (TB). TB infection interacts with Type 2 Diabetes (DM2), disproportionately affecting individuals who are routinely targeted by federal immigration practices. When two diseases interact and exacerbate one another within a larger structural context, thereby amplifying multiple disease interactions, this is called a syndemic. In this paper, we examine malnutrition in ICE detention as a pathway of bidirectional risks for and interactions between TB and DM2 among ICE detainees. Drawing from literature on detention conditions, TB, and DM2 rates along the U.S.-Mexico border, we propose an ICE-TB-DM2 syndemic model. We present a map displaying our proposed syndemic model to demonstrate the spatial application of syndemic theory in the context of ICE detention, strengthening the growing scholarship on syndemics of incarceration and removal.Light-duty gasoline vehicle (LDGV) tailpipe emission rates can be quantified based on pollutant concentrations measured using portable emission measurement systems (PEMS). Emission rates depend on exhaust flow. For simplified and micro-PEMS, exhaust flow is inferred from engine mass air flow (MAF) and air-to-fuel ratio. For many LDGVs, MAF is broadcast via the on-board diagnostic (OBD) interface. For some vehicles, only indirect indicators of MAF are broadcast. In such cases, MAF can be estimated using the speed-density method (SDM). The SDM requires an estimate of the engine volumetric efficiency (VE), which is the ratio of actual to theoretical MAF. VE is affected by intra-vehicle variability in the engine load and inter-vehicle variability in engine characteristics (e.g., the type of valvetrain). The suitability of SDM-based estimates of MAF in conjunction with simplified and micro-PEMS has not been adequately evaluated. Therefore, the objectives are to (1) quantify VE accounting for intra- and inter-vehiccations Simplified and micro portable emission measurement systems (PEMS) enable widespread measurement of vehicle exhaust emission. learn more As a cost saving measure, they estimate exhaust flow indirectly rather than via measurement, typically based on engine mass air flow (MAF). For some vehicles, MAF is not reported by the on-board diagnostic (OBD) system but can be inferred from other reported variables and volumetric efficiency (VE). However, VE is typically proprietary. Methods demonstrated here for estimating VE enable accurate quantification of emission rates, thereby enabling use of these PEMS for policy-relevant applications such as technology assessments, trends analysis, and emissions inventories.Circular RNAs (circRNAs) have been reported to exert vital roles in the tumorigenesis of non-small cell lung cancer (NSCLC). The study aimed to probe the function of circ_0017956 in NSCLC development. The expression of circ_0017956, microRNA (miR)-515-5p and integrin subunit beta 8 (ITGB8) was gauged by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. The proliferation detection was conducted employing Cell Counting Kit-8 (CCK-8) and colony formation assays. Transwell assay was performed to determine cell migratory and invasive abilities. Western blot was implemented for the measurement of related proteins. The targeted interactions among circ_0017956, miR-515-5p and ITGB8 were affirmed by dual-luciferase reporter assay, RNA immunoprecipitation (RIP) assay and RNA pull-down assay. The role of circ_0017956 in NSCLC tumor growth in vivo was studied by xenograft mice model. Circ_0017956 and ITGB8 abundances were overtly raised whereas miR-515-5p was low expressed in NSCLC tissues and cells.
