Despite enormous therapeutic advances, coronary artery disease (CAD) remains a global public health problem. Effective prevention of cardiovascular morbidity and mortality will require the development of new diagnostic and therapeutic strategies aimed at treating early, subclinical disease stages. These novel approaches are increasingly based on the molecular understanding of disease development. Molecular imaging, as it applies to CAD, describes diagnostic strategies targeting biomarkers associated with the development of atherosclerotic lesions. In analogy to applications in oncology, identification of subclinical disease and disease activity appear feasible. Novel therapeutic strategies include the development of targeted transport vehicles allowing drug delivery to specific cells or cell structures. Nanotechnology is expected to contribute to molecular strategies in the diagnosis and treatment of CAD. Of particular interest are bioengineered nanoparticles, which can be utilized as transport vehicles of diagnostic or therapeutic agents. However, further development is required before nanotechnology can be applied clinically. This manuscript also includes some recent patents on this topic.

Gaucher disease (GD) is a rare lysosomal disorder characterized by the accumulation of glycosphingolipids in macrophages resulting from glucocerebrosidase (GCase) deficiency. The accumulation of toxic substrates, which causes the hallmark symptoms of GD, is dependent on the extent of enzyme dysfunction. Accordingly, three distinct subtypes have been recognized, with type 1 GD (GD1) as the common and milder form, while types 2 (GD2) and 3 (GD3) are categorized as neuronopathic and severe.

Purpose: To compare the effectiveness and safety of CT-guided iodine-125 seed brachytherapy in conjunction with chemotherapy against chemotherapy alone for the management of intermediate and advanced non-small cell lung cancer (NSCLC) lacking oncogenic driving genes.
Methods And Materials: Retrospective analysis was conducted on clinical data from 128 patients diagnosed with intermediate and advanced non-small cell lung cancer who received iodine-125 combined with chemotherapy or chemotherapy alone due to the absence of oncogenic driver gene mutations. The patients in two groups were compared at 6-month follow-up for objective remission rate (ORR), Disease control rate (DCR), local progression-free survival (LPFS), overall survival (OS), clinical symptom improvement, and adverse events.

Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease, herein; we identified chemicals from herbs that inhibit α-Syn aggregation.

Extracellular vesicles (EVs), defined as membrane-bound vesicles released from all cells, are being explored for their diagnostic and therapeutic role in dry eye disease (DED). We systematically shortlisted 32 articles on the role of EVs in diagnosing and treating DED. The systematic review covers the progress in the last 2 decades about the classification and isolation of EVs and their role in DED.
