Phyllodes tumors (PTs) of the breast are considered a rare fibroepithelial neoplasms of the breast and are considered a challenging for both pathologists and surgeons. The World Health Organization (WHO) has classified PTs histologically as benign, borderline, and malignant. PTs can be detected in all ages; however, the median age of presentation is 45 years. PTs can mimic fibroadenoma in clinical presentations. Breast imaging is also similar to fibroadenomas. Cytological diagnosis of PTs by biopsy is usually unreliable. However, a core needle biopsy is superior to fine-needle aspiration. Surgery is considered the mainstay treatment for PTs of the breast with a goal of achieving negative margins. Adjuvant chemotherapy and radiation therapy use for malignant PTs are controversial.

An aqueous extract of Syzygium cumini seeds was utilized to green synthesize titanium dioxide nanoparticles (TiO₂ NPs). UV-Visible, DLS, FTIR, XRD, FESEM, TEM, SAED, EDAX, and photoluminescence spectroscopy techniques were employed to characterize the prepared TiO₂ nanoparticles. The rutile crystal structure of TiO₂ NPs was revealed by XRD study. The TEM and FESEM images of the TiO₂ NPs revealed an average particle size of 50–100 nm. We employed EDAX to investigate the elemental compositions of TiO₂ NPs. The O-Ti-O stretching bands appeared in the FTIR spectrum of TiO₂ NPs at wavenumbers of 495 cm⁻¹. The absorption edge peaks of TiO₂ NPs were found in the UV-vis spectra at 397 nm. The MTT study revealed that TiO₂ NPs effectively inhibited the growth of liver cancer Hep3 and Hep-G2 cells. The results of the corresponding fluorescent staining assays showed that TiO₂ NPs significantly increased ROS generation, decreased MMP, and induced apoptosis in both liver cancer Hep3 and Hep-G2 cells. TiO₂ nanoparticles lessened SOD, CAT, and GSH levels while augmenting MDA contents in Hep3 and Hep-G2 cells. In both Hep3 and Hep-G2 cells treated with TiO₂ NPs, the Bax, CytC, p53, caspase-3, -8, and -9 expressions were remarkably augmented, while Bcl-2 expression was reduced. Overall, these findings revealed that formulated TiO₂ NPs treatment considerably inhibited growth and triggered apoptosis in Hep3 and HepG2 cells.

Nanotechnology has emerged as the most popular research topic with revolutionary applications across all scientific disciplines. Tin oxide (SnO₂) has been gaining considerable attention lately owing to its intriguing features, which can be enhanced by its synthesis in the nanoscale range. The establishment of a cost-efficient and ecologically friendly procedure for its production is the result of growing concerns about human well-being. The novelty and significance of this study lie in the fact that the synthesized SnO₂ nanoparticles have been tailored to have specific properties, such as size and morphology. These properties are crucial for their applications. Moreover, this study provides insights into the synthesis process of SnO₂ nanoparticles, which can be useful for developing efficient and cost-effective methods for large-scale production. In the current study, green Pluronic-coated SnO₂ nanoparticles (NPs) utilizing the root extracts of Polygonum cuspidatum have been formulated and characterized by several methods such as UV–visible, Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray (EDAX), transmission electron microscope (TEM), field emission-scanning electron microscope (FE-SEM), X-ray diffraction (XRD), photoluminescence (PL), and dynamic light scattering (DLS) studies. The crystallite size of SnO₂ NPs was estimated to be 45 nm, and a tetragonal rutile-type crystalline structure was observed. FESEM analysis validated the NPs’ spherical structure. The cytotoxic potential of the NPs against HepG2 cells was assessed using the in vitro MTT assay. The apoptotic efficiency of the NPs was evaluated using a dual-staining approach. The NPs revealed substantial cytotoxic effects against HepG2 cells but failed to exhibit cytotoxicity in different liver cell lines. Furthermore, dual staining and flow cytometry studies revealed higher apoptosis in NP-treated HepG2 cells. Nanoparticle treatment also inhibited the cell cycle at G0/G1 stage. It increased oxidative stress and promoted apoptosis by encouraging pro-apoptotic protein expression in HepG2 cells. NP treatment effectively blocked the PI3K/Akt/mTOR axis in HepG2 cells. Thus, green Pluronic-F-127-coated SnO₂ NPs exhibits enormous efficiency to be utilized as an talented anticancer agent.

Introduction: Papillary carcinoma originating from a thyroglossal cyst is rare and peculiar, with majority of cases detected after surgery. Despite an excellent prognosis, its management remains controversial. Herein, we report the case of a 53-year-old woman who underwent Sistrunk procedure for a thyroglossal duct cyst and was subsequently confirmed to have papillary thyroid carcinoma. Presentation of case: A 53-year-old woman presented with an anterior midline neck mass for 7 years. The patient had no symptoms of hypo-or hyperthyroidism. Additionally, she had no history of compressive symptoms. Neck ultrasound revealed a well-defined 3.5 cm × 2.2 cm × 3 cm-sized cystic lesion inferior to the hyoid bone, with a peripheral solid component. Neck computed tomography revealed a well-defined 3.7 cm × 3.4 cm × 2.7 cm-sized cystic lesion with an enhanced central solid component with focal calcifications, inferior to the hyoid bone, and in contact with the anterior wall of the thyroid cartilage. Sistrunk procedure was performed. The patient was then diagnosed with papillary thyroid carcinoma with TNM stage pT2 and underwent total thyroidectomy as a follow-up procedure. Discussion: Thyroglossal duct cyst carcinoma is usually detected in the fourth decade of life with a higher prevalence in women. Neck ultrasound is performed during the initial radiological workup to assess the cyst and confirm the presence of the thyroid gland. Conclusion: The Sistrunk procedure is highly effective in low-risk patients. A more aggressive approach is required for high-risk patients. Highlights:

In this study, we synthesized, characterized, and explored the anti-microbial and anti-cancer effects of albumin–chlorogenic acid nanoparticles (NPs). Characterization studies with a UV-vis spectrophotometer, FTIR, PL spectrum, TEM, FESEM, XRD, and DLA analysis showed patterns confirming the physio–chemical nature of biogenic nanocomposites. Further, anti-microbial studies using bacterial strains Staphylococcus aureus, Streptococcus pneumonia, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Vibrio cholera, and fungal strain Candida albicans showed significant (p < 0.05) anti-bacterial and anti-fungal activities. Next, we used MDA-MB-435s, a human cell line, to evaluate the anti-cancer effects of albumin–chlorogenic acid NPs. Cytotoxic studies revealed its IC50 concentration at 24 μg/mL after a 24 h treatment of MDA-MB-435s cells. We chose this IC50 dose to analyze albumin–chlorogenic acid NPs anti-cancer effects in vitro. MDA-MB-435s cells exposed to our NPs were studied via AO/EtBr staining, cell cycle analyses via PI staining, the status of whole genomic damage via comet assay, levels of apoptotic cells via annexin V/PI staining, ROS generation via DCFH-DA staining, an assay of antioxidant enzymes catalase, superoxide dismutase, and antioxidant GSH, via ELISA analyses of apoptotic markers caspase-3, 8, 9, Bax, Bcl-2, CytC, and p53, PI3/AKT/mTOR pathway. Our results collectively showed albumin–chlorogenic acid NPs induced apoptosis via p53-dependent and PI3/AKT/mTOR inhibition in MDA-MB-435s cells. Our results denote albumin–chlorogenic acid NPs can be used as an effective candidate for anti-microbial and anti-cancer applications; however, further in vivo confirmatory studies are warranted.
