Article Abstract
Problem: Polycystic ovary syndrome (PCOS), a prevalent endocrine-metabolic disorder, presents considerable therapeutic challenges due to its complex and elusive pathophysiology.
Method Of Study: We employed three machine learning algorithms to identify potential biomarkers within a training dataset, comprising GSE138518, GSE155489, and GSE193123. The diagnostic accuracy of these biomarkers was rigorously evaluated using a validation dataset using area under the curve (AUC) metrics. Further validation in clinical samples was conducted using PCR and immunofluorescence techniques. Additionally, we investigate the complex interplay among immune cells in PCOS using CIBERSORT to uncover the relationships between the identified biomarkers and various immune cell types.
Results: Our analysis identified ACSS2, LPIN1, and NR4A1 as key mitochondria-related biomarkers associated with PCOS. A notable difference was observed in the immune microenvironment between PCOS patients and healthy controls. In particular, LPIN1 exhibited a positive correlation with resting mast cells, whereas NR4A1 demonstrated a negative correlation with monocytes in PCOS patients.
Conclusion: ACSS2, LPIN1, and NR4A1 emerge as PCOS-related diagnostic biomarkers and potential intervention targets, opening new avenues for the diagnosis and management of PCOS.

Background: We investigated circulating protein profiles and molecular pathways among various chronic kidney disease (CKD) etiologies to study its underlying molecular heterogeneity.
Methods: We conducted a proteomic biomarker analysis in the DAPA-CKD trial recruiting adults with and without type 2 diabetes with an eGFR of 25 to 75 mL/min/1.73m2 and a UACR of 200 to 5000 mg/g.

Cancer vaccines represent a transformative shift in oncology, aiming to prevent malignancies or treat established cancers by training the immune system to recognize tumor-specific or tumor-associated antigens. This review explores the diverse platforms and mechanisms supporting cancer vaccines, ranging from prophylactic vaccines such as HPV and hepatitis B vaccines that have significantly reduced virus-related cancers to therapeutic vaccines like Sipuleucel-T and T-VEC that extend survival in prostate cancer and melanoma. Vaccine types are classified, and delivery platforms including mRNA, peptide, dendritic cell and viral vector-based approaches are examined alongside pivotal clinical trial outcomes.

Follicular unit extraction (FUE) has become a leading technique in hair transplantation, yet optimal management of the donor area remains a clinical challenge. This systematic review analyzes intraoperative and postoperative interventions applied to the donor area in FUE hair transplantation, with a focus on both clinical outcomes and the cellular and molecular mechanisms involved in tissue repair, inflammatory response, and regenerative processes. A comprehensive literature search was conducted in PubMed and EMBASE (January 2000-June 2025), identifying clinical studies that evaluated donor area treatments and reported outcomes related to healing, inflammation, infection, and patient satisfaction.

The study addresses the critical issue of sepsis diagnosis, a life-threatening condition triggered by the body's immune response to infection that leads to mortality. Current diagnostic methods rely on the time-consuming assessment of multiple biomarkers by a series of tests, leading to delayed treatment. Here, we report a platform for developing a point-of-care (POC) device utilizing electrochemical immunosensors for the dual and rapid detection of sepsis biomarkers: Procalcitonin (PCT), Interleukin-6 (IL-6), and C-reactive protein (CRP) as host markers and lipopolysaccharide (LPS) as a pathogen marker.

The etiology of uveitis, choroid inflammation, is diverse, the disease is often recurrent, difficult to treat, and frequently results in disability at a young age. Studies investigating the tear fluid composition in uveitis have revealed promising biomarkers relevant for prognosis and treatment optimization. This review presents literature data on changes in the tear fluid content of proteins involved in local immune responses, intercellular interactions, proteolytic and free radical processes, nitric oxide metabolism, and other metabolic pathways in different forms of uveitis.
