Fourier-transform infrared (FT-IR) spectral imaging was used for analyzing biochemical changes in tumor cells. Metabolic parameters of human lung A549/8 adenocarcinoma and U87 glioma cells were compared under stress conditions in culture along with tumor progression after cell implantation onto the chick embryo chorio-allantoic membrane. In cell culture, glucose consumption and lactic acid release were higher in U87 cells. A549/8 cells were less sensitive to oxidative stress as observed through changes in fatty acyl chains. In vivo biochemical mapping of highly (U87) vs. poorly (A549/8) angiogenic tumors provided results comparable to culture models. Therefore, FT-IR imaging allows detecting subtle chemical changes in tumors, which might be useful for diagnosis.

This review addresses the significant advancements in the identification of blood-based prognostic biomarkers for tuberculosis (TB), highlighting the importance of early detection to prevent disease progression. The manuscript discusses various biomarker categories, including transcriptomic, proteomic, metabolomic, immune cell-based, cytokine-based, and antibody response-based markers, emphasizing their potential in predicting TB incidence. Despite promising results, practical application is hindered by high costs, technical complexities, and the need for extensive validation across diverse populations.

Background: Heterogeneity in the progression of clinical dementia poses a significant challenge, impeding the effectiveness of current therapies for Alzheimer's disease (AD). To decipher the molecular mechanisms governing heterogeneity in AD progression that remains a critical knowledge gap precluding rational therapeutic design, we investigated the biochemical and biophysical properties of tau present in the inferior temporal gyrus (ITG) and prefrontal cortex (PFC) brain regions of AD patients who had varying disease progression rates. To explore gene expression changes in the ITG which are associated with tau pathology and cognitive decline, we used RNA sequencing for molecular characterization of patients displaying tau and clinical heterogeneity.

Background: A better understanding of the molecular process that drive Alzheimer's disease(AD) are required to develop effective biomarkers and therapies. This includes determining how essential elements like Fe, Cu and Zn are involved in the disease. In the literature there is debate over the role of iron in AD and there are reports of increased, decreased and unchanged levels of Fe in AD brain.
