Abstract Alzheimer’s disease (AD) stands as the predominant form of dementia, presenting significant and escalating global challenges. Its etiology is intricate diverse, stemming from a combination factors such aging, genetics, environment. Our current understanding AD pathologies involves various hypotheses, cholinergic, amyloid, tau protein, inflammatory, oxidative stress, metal ion, glutamate excitotoxicity, microbiota-gut-brain axis, abnormal autophagy. Nonetheless, unraveling interplay among these pathological aspects pinpointing primary initiators require further elucidation validation. In past decades, most clinical drugs have been discontinued due to limited effectiveness or adverse effects. Presently, available primarily offer symptomatic relief often accompanied by undesirable side However, recent approvals aducanumab ( 1 ) lecanemab 2 Food Drug Administration (FDA) present potential in disrease-modifying Nevertheless, long-term efficacy safety need Consequently, quest for safer more effective persists formidable pressing task. This review discusses pathogenesis, advances diagnostic biomarkers, latest updates trials, emerging technologies drug development.

Abstract The blood brain barrier (BBB) limits the application of most therapeutic drugs for neurological diseases (NDs). Hybrid cell membrane‐coated nanoparticles derived from different types can mimic surface properties and functionalities source cells, further enhancing their targeting precision efficacy. Neuroinflammation has been increasingly recognized as a critical factor in pathogenesis various NDs, especially Alzheimer's disease (AD). In this study, novel membrane coating is designed by hybridizing platelets chemokine (C–C motif) receptor 2 (CCR2) cells are overexpressed to cross BBB target neuroinflammatory lesions.

Abstract Amyloid beta‐protein (AβA β ) is a main hallmark of Alzheimer's disease (AD), and low amount Aβ protein accumulation appears to be potential marker for AD. Here, an electrochemical DNA biosensor based on polyamide/polyaniline carbon nanotubes (PA/PANI‐CNTs) developed with the aim diagnosing AD early using simple, low‐cost, accessible method rapidly detect Aβ42 in human blood. Electrospun PA nanofibers served as skeleton successive situ deposition PANI CNTs, which contribute both high conductivity abundant binding sites aptamers. After aptamers are immobilized, this aptasensor exhibits precise specific detection blood within only 4 min extremely fast response rate, lower limit, excellent linear range. These findings make significant contribution advancing development serum‐based techniques Aβ42, thereby paving way improved diagnostic capabilities field

Abstract Objectives Human tear analysis holds promise for biomarker discovery, but its clinical utility is hindered by the lack of standardized reference values, limiting interindividual comparisons. This study aimed at developing a protocol normalizing metabolomic data from human tears, enhancing potential identification. Methods Tear profiling was conducted on 103 donors (64 females, 39 males, aged 18–82 years) without ocular pathology, using AbsoluteIDQ™ p180 Kit targeted metabolomics. A predictive normalization model incorporating age, sex, and fasting time developed to correct variability. Key metabolites six compound families (amino acids, biogenic amines, acylcarnitines, lysophosphatidylcholines, phosphatidylcholines, sphingomyelins) were identified as references. The approach validated Linear Discriminant Analysis (LDA) test ability classify donor sex based metabolite concentrations. Results Metabolite concentrations exhibited significant model, which predicted “concomitant” each family, successfully reduced this Using ratio observed-to-predicted concentrations, enabled robust comparisons across individuals. LDA classification acylcarnitine C4 achieved 78 % accuracy, correctly identifying 92 female donors. outperformed traditional statistical machine learning methods (Lasso logistic regression Random Forest classification) in discrimination Conclusions novel significantly improves reliability metabolomics enabling facilitates discovery mitigating variability may be extended other biological fluids, applicability precision medicine.
