Despite the therapeutic potential of the primary vaccine series, a lack of confidence in the COVID-19 booster vaccine poses a threat to public health and undermines its coverage at the national, regional, and global levels. This study aimed to understand COVID-19 booster vaccine confidence (CBVC) among Bangladeshi adults aged 18-49 and the potential predictors of CBVC. In line with STROBE guidelines, a face-to-face cross-sectional survey was conducted from June 15 to August 31, 2023 during the spread of the SARS-CoV-2 Omicron variant.

We report the results of structural, functional and genetic studies on the CD33 sialic acid- binding receptor that reveal how non-coding variants in CD33 alter risk for Alzheimer's disease (AD). The full-length CD33 isoform, whose expression is upregulated by non-coding AD-risk alleles, preferentially forms dimers at the cell surface, where they interact with AD-related proteins (clusterin and Aβ). This interaction induces CD33 inhibitory signalling and downregulates protective microglial functions including phagocytic removal of amyloid plaques.

The innate immune gene 33, encoding a myeloid inhibitory sialic acid-binding receptor, is associated with Alzheimer's disease (AD) susceptibility. The AD-associated risk variant reduces splicing of the sialic acid-binding domain and increases expression of the full-length (sialic acid-binding) CD33 isoform seven-fold compared to the protective genotype. Here we identify CD45 as an immune cell-specific sialic acid-dependent CD33 binding partner, whose phosphatase activity is inhibited by CD33.

Geranylgeranyl diphosphate synthase (GGDPS) produces the 20-carbon isoprenoid species used in protein geranylgeranylation reactions. Inhibition of GGDPS has emerged as a novel means of disrupting the activity of geranylgeranylated proteins in cancers such as myeloma and osteosarcoma. We have focused on developing a series of isoprenoid triazole bisphosphonate-based GGDPS inhibitors, demonstrating a complex structure-activity relationship (SAR), not only at the enzymatic level, but also at the cellular and whole organism levels.

Geranylgeranyl diphosphate synthase produces the isoprenoid geranylgeranyl diphosphate, which is used in protein geranylgeranylation. Our previous work illustrates that geranylgeranyl diphosphate synthase inhibitors (GGSIs) disrupt Rab-mediated protein trafficking in cells, inducing the unfolded protein response pathway and apoptosis. Structure-function studies of our GGSIs, which are isoprenoid triazole bisphosphonates, have revealed a complex relationship between GGSI structure and enzymatic, cellular, and in vivo activities.

The global spread of SARS-CoV-2 has prompted a crucial need for accurate medical diagnosis, particularly in the respiratory system. Current diagnostic methods heavily rely on imaging techniques like CT scans and X-rays, but identifying SARS-CoV-2 in these images proves to be challenging and time-consuming. In this context, artificial intelligence (AI) models, specifically deep learning (DL) networks, emerge as a promising solution in medical image analysis.

Background: The COVID-19 pandemic presented a 'double-edged sword' for older adults: not only were they more susceptible to the virus, but its broader consequences also exacerbated other challenges, particularly those related to psychosocial well-being. Limited evidence exists on how older adults perceive the pandemic and its impact on their well-being and the role of social workers in addressing these challenges, particularly in resource-limited settings like Nigeria.

Aim: This study explored older adults' perceived risks regarding COVID-19, its impact on their psychosocial well-being, and the role of social workers in addressing these challenges in Nigeria.

Conventional banks are 'indirectly' allowed to take more risk under the shadow of sovereign guarantees. Banks commit moral hazards as any major banking crisis will be 'cushioned' by deposit insurance and bailed out using the taxpayer's money. This study offers an alternative explanation for the determinants of banks' credit risk, particularly those from the Islamic regions.
