Article Abstract
Paratuberculosis and bovine tuberculosis are two mycobacterial diseases of ruminants which have a considerable impact on livestock health, welfare, and production. These are chronic "iceberg" diseases which take years to manifest and in which many subclinical cases remain undetected. Suggested biomarkers to detect infected or diseased animals are numerous and include cytokines, peptides, and expression of specific genes; however, these do not provide a strong correlation to disease. Despite these advances, disease detection still relies heavily on dated methods such as detection of pathogen shedding, skin tests, or serology. Here we review the evidence for suitable biomarkers and their mechanisms of action, with a focus on identifying animals that are resilient to disease. A better understanding of these factors will help establish new strategies to control the spread of these diseases.

Microfluidic paper-based analytical devices for food spoilage detection: emerging trends and future directions.
Talanta

Faculty of Applied Sciences, Ton Duc Thang University, Ho Chi Minh City, Viet Nam. Electronic address:
Food spoilage poses a global challenge with far-reaching consequences for public health, economic stability, and environmental sustainability. Conventional analytical methods for spoilage detection though accurate are often cost-prohibitive, labor-intensive, and unsuitable for real-time or field-based monitoring. Microfluidic paper-based analytical devices (μPADs) have emerged as a transformative technology offering rapid, portable, and cost-effective solutions for food quality assessment.

Background And Objectives: α-Synuclein seed amplification assays (αSAAs) can improve the diagnosis of synucleinopathies and detect α-synuclein (αSyn) copathology in vivo in clinical practice. We aimed to evaluate the diagnostic performance of αSAA for detecting αSyn in CSF for diagnosing dementia with Lewy bodies (DLB) in a clinical cohort of cognitively impaired individuals. We explored how the coexistence of Alzheimer disease (AD) and αSyn pathology influences biomarker levels and clinical profiles.

Compared with efficient anodic luminol electrochemiluminescence (ECL), the disadvantage of cathodic ECL is that luminol cannot be electrochemically oxidized in a direct manner, and the conversion efficiency of dissolved oxygen (DO) as the coreactant to reactive oxygen species (ROS) is poor, which limits its application. Therefore, it is necessary to develop a functional catalyst suitable for the luminol-DO ECL system to directly trigger cathodic ECL. In this study, a coordination microenvironment modulation strategy was proposed.

Importance: Black individuals have a twofold higher rate of prostate cancer death in the US compared with the average population with prostate cancer. Few guidelines support race-conscious screening practices among at-risk Black individuals.
Objective: To examine structural factors that facilitate or impede access to prostate cancer screening among Black individuals in the US.
Accounting for endoscopic screening in colorectal cancer risk models.

Background: Colorectal cancer (CRC) risk models routinely adjust for endoscopic screening because of a) possible confounding with other risk factors and b) possible alteration of natural history of the disease due to adenoma detection and removal.
Methods: In this study, we defined a subject as screen-covered (SC) if a colonoscopy was performed in the past 10 years, and not screen-covered (NSC) otherwise. We created CRC risk models separately for SC and NSC subjects (HRSC, HRNSC) and then obtained a screening-coverage adjusted HR estimate (HRfull) based on a weighted average of ln(HRSC) and ln(HRNSC) with weight equal to the proportion of SC person-time in the NHS population.
