BACKGROUND/OBJECTIVES:
Rosa hybrida has been demonstrated to exert biological effects on several cell types. This study investigated the efficacy of the edible ethanol extract of R.hybrida (EERH) against human colorectal carcinoma cell line (HCT116) cells.MATERIALS/METHODS: HCT116 cells were cultured with different concentrations of EERH (0, 400, 600, 800, and 1,000 µg/mL) in Dulbecco’s modified Eagle medium. Cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide and viable cell counting assays. Cell cycle pattern was observed by flow cytometry analysis. The wound-healing migration assay, invasion assay, and zymography were used to determine the migratory and invasive level of HCT116 cells treated with EERH. The protein expression and binding ability level of HCT116 cells following EERH treatment were analyzed via immunoblotting and the electrophoretic mobility shift assay.
RESULTS:
EERH suppressed HCT116 cell proliferation, thus arresting the G1-phase cell cycle.It also reduced cyclin-dependent kinases and cyclins, which are associated with p27KIP1 expression. Additionally, EERH differentially regulated the phosphorylation of extracellular signal-regulated kinase 1/2, c-Jun NH2-terminal kinase, p38, and protein kinase B. Moreover, EERH treatment inhibited the enzymatic activity of matrix metalloproteinase-9 (MMP-9) and MMP-2, resulting in HCT116 cell migration and invasion. The EERH-induced inhibition of MMP-9 and MMP-2 was attributed to the reduced transcriptional binding of activator protein-1, specificity protein-1, and nuclear factor-κB motifs in HCT116 cells. Kaempferol was identified as the main compound contributing to EERH's antitumor activity.
CONCLUSION
EERH inhibits HCT116 cell proliferation and metastatic potential. Therefore, it is potentially useful as a preventive and curative nutraceutical agent against colorectal cancer.

Psychiatry Investigation 2025;22(5):574-582
Objective:
A humanities-based approach to understanding the brain can yield valuable insights, advancing neuroscience and enhancing mental, emotional, and social well-being. This study was aimed at exploring how engagement in literature-related activities stimulates brain activity in the prefrontal cortex.
Methods:
We recruited 24 healthy male participants aged 20 to 29 years. They completed clinical scales assessing depression, anxiety, attention, and humanistic knowledge. They also performed six tasks comprising various literature-related cognitive challenges while hemodynamic changes in their frontal cortices were measured using functional near-infrared spectroscopy.
Results:
Task 1 (word memory and recognition) increased activation in the ventrolateral prefrontal cortex (VLPFC), as did Task 2 (emotional words classification), which also elevated activity in the left orbitofrontal cortex (OFC). Task 3 (understanding context) increased activation in the dorsolateral PFC (DLPFC). Tasks 4 (interpersonal relationship) and 5 (listening, memory, understanding, and expression) drove similar increases in the frontopolar and DLPFC regions. Task 6 (creative activities using characters and items) significantly activated multiple regions, including the right and left VLPFC and OFC. Humanistic knowledge scores were positively correlated with left and right DLPFC activation in Tasks 3 and 5, respectively. Conversely, Task 6 showed negative correlations between attention-deficit/hyperactivity disorder scores and both right DLPFC and right OFC activation.
Conclusion
This study identified key brain regions involved in literature activities. Complex activities (semantic processing, understanding and creative expression, decision-making and emotional regulation, etc.) stimulated various regions of prefrontal cortices, including the VLPFC, DLPFC, and OFC.
3.Regional anesthesia for rapid recovery after orthopedic surgery

Orthopedic surgery is becoming increasingly common, particularly among older adults, due to population aging and the rising incidence of degenerative conditions. Older patients frequently have multiple comorbidities, which elevate the risk of surgical complications. Effective pain management is crucial in facilitating recovery and reducing the likelihood of postoperative complications. This review examines the role of regional anesthesia in optimizing recovery outcomes for orthopedic patients.Current Concepts: Regional anesthesia significantly reduces opioid consumption, which in turn mitigates side effects such as nausea, vomiting, respiratory depression, and urinary retention. It also promotes early mobilization, which is crucial for functional recovery, and helps prevent complications such as deep vein thrombosis and muscle atrophy. Advanced techniques like local infiltration analgesia and motor-sparing blocks offer effective pain relief while preserving muscle strength. This not only facilitates faster rehabilitation but also reduces the length of hospital stays. These advantages underscore the importance of regional anesthesia in improving surgical outcomes and expediting recovery.Discussion and Conclusion: Regional anesthesia is crucial in improving recovery after orthopedic surgery by providing effective pain management, facilitating early mobilization, and minimizing complications. It is essential to customize the anesthetic approach based on the specific surgical procedure and the patient’s overall health to achieve optimal outcomes.
