Apolipoprotein E dysfunction in Alzheimer's disease: a study on miRNA regulation, glial markers, and amyloid pathology.

Introduction: Apolipoprotein E (ApoE) plays a crucial role in lipid homeostasis, predominantly expressed in astrocytes and to a lesser extent in microglia within the central nervous system (CNS). While the allele is the strongest genetic risk factor for late-onset Alzheimer's disease (AD), its precise role in AD pathogenesis remains elusive. -knockout (-ko) mice, mice expressing human , and human carriers exhibit similar deficits in lipid metabolism, cognitive and behavioral functions, and neurodegeneration.

3-Dimensional morphological characterization of neuroretinal microglia in Alzheimer's disease via machine learning.

Alzheimer's Disease (AD) is a debilitating neurodegenerative disease that affects 47.5 million people worldwide. AD is characterised by the formation of plaques containing extracellular amyloid-β (Aβ) and neurofibrillary tangles composed of hyper-phosphorylated tau proteins (pTau).

Sidelobe suppressed Bessel beams for one-photon light-sheet microscopy.

The Bessel beam (BB) has found widespread adoption in various forms of light-sheet microscopy. However, for one-photon fluorescence, the transverse profile of the beam poses challenges due to the detrimental effect of the sidelobes. Here, we mitigate this issue by using a computer-generated phase element for generating a sidelobe suppressed Bessel beam (SSBB).

Assessment of public health laboratory preparedness and response in WHO South-East Asia region during the COVID-19 pandemic: lessons learned and future directions.

This Health Policy reviews the preparedness and response of public health laboratories in the WHO South-East Asia Region (SEAR) during the COVID-19 pandemic. Through a scoping review and in-depth interviews with key stakeholders, the study identifies successes, challenges, and lessons learned from available literature and the perspective of senior laboratory leaders. Key themes include human resources, health information systems, diagnostic capacity, public risk communication, biosafety, biosecurity, funding, and laboratory network coordination.

Seasonal influenza vaccination: A global review of national policies in 194 WHO member states in 2022.

Introduction: Seasonal influenza vaccination prevents severe influenza disease and death. The World Health Organization (WHO) encourages all countries to consider annual seasonal influenza vaccination for health workers, people with chronic conditions, older adults, pregnant women and other high-risk populations as relevant for their national context. This paper provides a global update on the status of countries' influenza vaccination policies and programmes as of December 2022.
