Cited by 15 •
2014
A novel methodology that is employed for the treatment of recurrent glioblastomas is described. This treatment approach employs the application of alternating electric tumor treating fields (TTFields), known as TTF Therapy in combination with bevacizumab, a targeted agent that is currently FDA approved as monotherapy.

2025
This video demonstrates an in vitro technique to study the impact of antimicrobial treatment on Pseudomonas aeruginosa (Pa) aggregates. Fluorescently-labeled Pa cells are grown as aggregates, mimicking the growth pattern during infection. Upon challenging the aggregates with a sublethal concentration of the antibiotic colistin, the real-time assessment of the bacteria-antibiotic interaction is performed via fluorescence microscopy.

Combination of High Ligation and Intraoperative Embolization Using Polidocanol for Treatment of Varicoceles
0 Views •
2023
To reduce the postoperative recurrence rate of varicocelectomy, we combined high ligation of varicocele with intraoperative embolization. We injected polidocanol from the spermatic vein during surgery to embolize the branches of the spermatic vein and collateral veins. This is an alternative surgical method for the treatment of varicocele.

2014
In this study, a novel platform to investigate intraneuronal molecular signatures of treatment response in bipolar disorder (BD) was developed and validated. Olfactory epithelium from BD patients was obtained through nasal biopsies. Then laser-capture microdissection was combined with Real Time RT PCR to investigate the molecular signature of lithium response in BD.

2015
Pancreatic cancer stem cells (CSCs) can be expanded in vitro using the anchorage-independent sphere culture technique, which represents a powerful tool to study CSC biology and can serve as the first step to develop novel CSC-targeting therapies. Here the methodology for expanding, analyzing and targeting of pancreatic CSCs is provided.
FAQs
Researchers interpret combined effects by comparing them with the performance of each intervention alone. A synergistic result means the combination exceeds the expected joint effect, whereas additivity indicates the expected combined effect and antagonism indicates a weaker result. These categories help distinguish genuine cooperation from simple accumulation of activity.
Drug choice, dose, sequence, and timing can change the observed interaction. A pair may behave differently when administered together than when one treatment precedes the other. Combination studies therefore test these variables rather than treating a regimen as fixed. This design can expose complementary action, resistance-related benefit, or added toxicity.
Patterns in response can show whether two interventions contribute distinct but compatible effects. When a combination improves activity beyond an individual treatment, investigators can examine whether the treatments act through complementary mechanisms or help address resistance. Such findings may guide rational therapy design and identify response patterns useful for developing biomarkers.
A basic investigation selects candidate interventions, varies their doses and schedules, and compares combined treatment with the corresponding single treatments. Researchers then measure responses in tumor cells, experimental models, or clinical settings and classify the interaction as synergistic, additive, or antagonistic. The resulting comparison shows whether the proposed regimen provides a meaningful advantage.
Investigators can examine combinations in tumor cells, other cancer models, or clinical settings, depending on the stage and purpose of the research. Cell and model studies help evaluate interaction patterns and treatment conditions, while clinical investigations assess how efficacy and toxicity relate in patients. Using these settings supports progression from initial evidence toward translation.
A combination is not judged only by whether it improves tumor-related outcomes. Researchers also examine how its efficacy relates to toxicity, because adding treatments can alter the overall therapeutic value of a regimen. This balance helps determine whether an observed interaction supports further development and whether treatment selection should be tailored to individual patient characteristics.
