Efficient methods and universal DNA elements are eagerly required for the expression of proteins and the production of target chemicals in synthetic biology and metabolic engineering. This paper develops a customized-design approach by utilizing the host-independent T7 expression system (HITES), which facilitates the rational design and rapid construction of T7 expression systems. Firstly, the EL (Upper-limit value of initial enzyme activity) value is discovered to play a pivotal factor in the successful construction of the T7 expression system, different host strains exhibit varying EL values, and this study presents a method to measure the EL values.

Mutations in the SLC25A38 gene are responsible for the second most common form of congenital sideroblastic anemia (CSA), a severe condition for which no effective treatment exists. We developed and characterized a K562 erythroleukemia cell line with markedly reduced expression of the SLC25A38 protein (A38-low cells). This model successfully recapitulated the main features of CSA, including reduced heme content and mitochondrial respiration, increase in mitochondrial iron, ROS levels and sensitivity to oxidative stress.

Non-classical MHC class I genes which, compared to classical MHC class I, are typically less polymorphic and have more restricted expression patterns are attracting interest because of their potential to regulate immune responses to various pathogens. In salmonids, among the numerous non-classical MHC class I genes identified to date, L lineage genes, including Sasa- and , are differentially induced in response to microbial challenges. In the present study, we show that while transcription of both and are induced in response to SAV3 infection the transcriptional induction patterns are distinct for each gene.

Socioeconomic Status and Stroke: A Review of the Latest Evidence on Inequalities and Their Drivers.

Stroke

December 2024

School of Life Course and Population Health Sciences, King's College London, United Kingdom (D.Y., E.E., M.S.-B., W.K., C.W., I.J.M.).

The latest research on socioeconomic status (SES) and stroke continues to demonstrate that individuals with low SES are at a higher risk of stroke, receive lower-quality care, and experience poorer outcomes. Despite growing evidence on the impact of SES on stroke, gaps remain in understanding the underlying mechanisms and the influence of SES in different contexts, particularly in low- and middle-income countries. This narrative review builds upon our previous reviews from 2006 to 2015, focusing on studies published since 2015 to update on the influence of SES on stroke.

Infectious Diseases Department, Istituto Superiore di Sanità, Viale Regina Elena, 299, 00161, Rome, Italy.

Migratory birds reach Europe from sub-Saharan Africa, and some avian species may harbor and transport infected ectoparasites, mainly ticks, native to the territories of departure. In 2022, a project focused on identifying the introduction of pathogens in Italy from Africa via migratory birds represented an important opportunity to investigate this particular route of tick dispersal. Among ticks collected from migratory birds on the island of Ventotene, Latium Region, we found one larva of a soft tick on a common whitethroat (Curruca communis) that was morphologically and molecularly identified to the species level as Argas (Persicargas) persicus (Oken 1818).
