    Abstract Investigating combined treatment methodologies is crucial for addressing the complex nature of cancer. As an emerging strategy, nano-biotechnology encourages the design of unique nanocarriers possessing simultaneous therapeutic application properties. This study aims to explore the combined effects of photodynamic and anticancer treatments using a multifunctional nanocarrier system co-administering the photosensitizer IR780 and the anticancer agent curcumin (Cur) on lung cancer cells. Nanocarriers were prepared by encapsulation IR780 and Cur inside polyethylene glycol-capped mesoporous silica nanoparticles (Cur&IR780@MSN). Various concentrations of nanocarriers were evaluated on A549 cells following 5 min NIR laser light (continuous wave, 785 nm, 500 mW/cm

    Abstract Background: FOLFIRINOX and gemcitabine-nabpaclitaxel (GnP) are standard first-line treatment regimens for advanced pancreatic ductal adenocarcinoma (PDAC). However, currently, there is a lack of predictive biomarkers to aid in the treatment selection. We aimed to explore the prognostic and predictive value of class III β-Tubulin (TUBB3) and human equilibrative nucleoside transporter 1 (hENT1) expression, which have previously been shown to be associated with taxane and gemcitabine resistance in advanced PDAC.
    Methods: We conducted a retrospective analysis of 106 patients with advanced PDAC treated with GnP and/or FOLFIRINOX at our institution. TUBB3 and hENT1 immunohistochemical staining was performed on tumor specimens and subsequently evaluated based on the intensity and percentage of expression.
    Results: In patients who received the GnP regimen, a high combined score (TUBB3
    Conclusion: Our findings indicate that tumor TUBB3 and hENT1 expression may predict the efficacy of the GnP regimen, and low TUBB3 and high hENT1 expression (TUBB3

    Abstract Background: Various types of nasal tampons are used for packing after septoplasty. Intranasal splints are widely used as they are more advantageous than other materials regarding the lower complication rates of synechia, and lesser pain during removal. However, there is no consensus on the timing of intranasal splint removal after septoplasty operations.
    Aim: In this study, we aimed to investigate the effects of removal time of intranasal splints on postoperative complications after septoplasty.
    Methods: One hundred patients who had septoplasty were randomly divided into two groups according to splint removal time. In group I, the splints were removed on the third postoperative day and in group II, splints were removed on the seventh postoperative day. Pain during splint removal was evaluated by visual analog scale (VAS). Complications of hemorrhage, septal hematoma, crusting, mucosal injury, and infection were recorded during splint removal and compared. In the first postoperative month, hemorrhage, crusting, mucosal injury, infection, synechia, and in the second postoperative month, synechia and perforation rates were compared between two groups.
    Results: Mucosal crusting was significantly higher in group II during splint removal. There was no statistically significant difference between the two groups regarding the complication rates and pain scores. Our findings showed no significant difference in pain scores during splint removal and postoperative complications between the two groups except for mucosal crusting.
    Conclusion: Based on our findings, although there is no consensus on the optimal time for splint removal, earlier removal of splints can be considered a favorable option after septoplasty operations.

    Abstract Background/aim: β-Catenin is a multifunctional protein, which is localized to different subcellular compartments of the normal colon epithelium. The hyperactivation of Wnt pathway results in the nuclear accumulation of β-catenin and induction of colorectal carcinogenesis. Although N-terminally hypo-phosphorylated β-catenin (active β-catenin) is known as the transcriptionally active form, phospho-S33/S37/T41-β-catenin (phospho-β-catenin) can also accumulate in the nucleus. In this study, we aimed to characterize the subcellular distribution of phospho-β-catenin and the other forms of β-catenin in normal colon epithelium and colorectal cancer (CRC).
    Materials and methods: Phosphorylated, hypo-phosphorylated, and the total pool of β-catenin were evaluated in colon epithelium and CRC using immunohistochemistry, immunofluorescence staining, and western blotting. Tissue microarrays were used to determine the expression pattern of phospho-β-catenin in CRC samples.
    Results: Almost 11% (49/452) of CRCs expressed moderate to high levels of phospho-β-catenin in the nucleus. In addition, hypo-phosphorylated and phosphorylated forms of β-catenin localized to different subcellular regions in normal colon epithelium and CRC. Immunoblotting experiments suggested that truncated phospho-β-catenin forms can be found in CRCs.
    Conclusion: Phospho-β-catenin accumulates in the nucleus and different molecular weight β-catenin proteins are present in colon cancer cells. To elaborate on the functional significance of nuclear phospho-β-catenin, further studies should be performed.

    Abstract Background and aim: Tyrosine kinase inhibitors (TKIs) have dramatically improved chronic myeloid leukemia (CML) prognosis. However, TKIs are associated with dyslipidemia and impaired glucosehomeostasis. Triglyceride-to-high-density lipoprotein cholesterol ratio (TG/HDL-C) is proposed to be an indicator of insulin resistance and atherogenic index, but there is no research on TG/HDL-C alterations in patients receiving TKIs for CML. We aimed to evaluate relationships between TKI type/count, clinical characteristics, and laboratory results (particularly TG/HDL-C) in CML patients.
    Patients and methods: A total of 104 patients with chronic phase CML were enrolled in the study. All patients received initial imatinib therapy at 400 mg daily, the type or dose of TKI was then changed according to treatment response and clinical outcomes. Patients were compared with respect to TG/HDL-C categorization (>2.5 versus <2.5), number of TKIs used, and use of imatinib as the only TKI.
    Results: The median TG/HDL-C was 2.82 (1.03-17.33) and this ratio was higher than 2.5 in 59 (56.7%) patients. Patients with high TG/HDL-C had a significantly higher age than patients with low values (P < 0.001). Recipients of more than one TKI had higher EUTOS risk score and white blood cell (WBC) count (P < 0.05). Recipients of imatinib as the only TKI had higher age, low EOTUS risk score, low WBC, and low neutrophil count (all, P < 0.05).
    Conclusion: TG/HDL-C values were not associated with the number of different TKIs used or the use of imatinib only in chronic-phase patients with CML. Further large-scale prospective studies are needed to determine whether TG/HDL-C can be used for diagnostic or prognostic purposes in TKI recipients.
