Objective: To establish the efficiency of ultrasonographically guided transvaginal adnexal cyst aspiration as a treatment and diagnostic method.
Study Design: In 72 patients with an adnexal cystic mass, transvaginal ultrasound guided cyst aspiration was performed. Before the procedure, presence of primary malignant disease was excluded by gynecologic and ultrasound examination. Cyst content was sent for cytological analysis. Cytological findings were staged according to Papanicolaou. Patients were re-examined 3 and 6 months after the ultrasound intervention. Cysts measuring 3 cm or more in diameter were considered to be recurrence of the disease.
Results: Recurrence of the disease appeared in 32 cases (44%) and was more common with larger cysts. Malignant cells were found in one case (1.5%), a recurrent ovarian cancer, previously treated by surgery and chemotherapy.
Conclusion: In our study, ultrasound guided aspiration of adnexal cysts was not shown to be an efficient method of treatment because of the high recurrence rate. It may be used in selected patients at high anaesthesiologic risk for surgery as a therapeutic or a diagnostic procedure.

The introduction of fluorescence imaging (FLI) in near-infrared II sub-channels (NIR-IIb, 1500-1700 nm) has revolutionized the ability to explore complex patho-physiological settings . Despite the transformative potentials, the development of organic NIR IIb dyes encounters considerable difficulties, and only a limited number of such fluorophores have been developed so far. This review systematically introduces design strategies of organic NIR-IIb fluorophores classified by molecular scaffolds, mainly including cyanine dyes and D-A-D small molecule dyes.

Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.
Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.

The critical need for rapid cancer diagnosis and related illnesses is growing alongside the current healthcare challenges, unfavorable prognosis, and constraints in diagnostic timing. As a result, emphasis on surface-enhanced Raman spectroscopy (SERS) diagnostic methods, including both label-free and labelled approaches, holds significant promise in fields such as analytical chemistry, biomedical science, and physics, due to the user-friendly nature of SERS. Over time, the SERS detection sensitivity and specificity with nanostructured materials for SERS applications (NMs-SERS) in different media have been remarkable.
