Significance of PD-L1 and Tumor Microenvironment in Laryngeal Squamous Cell Cancer.

Background: Despite the considerable advancement in the field of medicine over recent decades, laryngeal cancer continues to be a challenge. The field of immune oncology has generated promising immunomodulation therapies and opened up new ways of treatment.

Methods: Our retrospective study included 102 patients diagnosed with laryngeal squamous cell cancer (LSCC).

Screen-printed interdigitated microelectrodes employment in dielectrophoretic manipulation of MWCNTs.

As key enablers of Industry 4.0 and Internet of Things, sensors are among the first devices which are to encounter fast physical transformation (from rigid to flexible) as of large-scale utilization of printing technologies. In order to step-up this process, adaptation of conventional fabrication technologies (based on metallization) employed in sensors' development should be tested and demonstrated.

Improving Printability of Polytetrafluoroethylene (PTFE) with the Help of Plasma Pre-Treatment.

Polytetrafluoroethylene (PTFE) is a potential candidate for the fabrication of flexible electronics devices and electronics with applications in various extreme environments, mainly due to its outstanding chemical and physical properties. However, to date, the utilization of PTFE in printing trials has been limited due to the material's low surface tension and wettability, which do not ensure good adhesion of the printing ink at the level of the substrate. Within this paper, successful printing of PTFE is realized after pre-treating the surface of the substrate with the help of dielectric barrier discharge non-thermal plasma.

Perioperative substitution testosterone therapy in patients with advanced head and neck squamous cell carcinoma.

Testosterone replacement therapy is becoming more and more popular in men as "anti-aging medicine". Testosterone has beneficial effects on body mass and muscle gain, and much research has examined testosterone in palliative cancer therapy for oncology patients. In addition to direct effects on weight gain, testosterone improves mood and self-confidence, strength, libido, muscle mass, bone density, and cognitive functions and reduces the risk of cardiovascular disease.

Long-Term Care and Follow-Up in Laryngeal Cancer Patients: A Multicenter Retrospective Analysis.

Purpose: We conducted an outcome analysis on surgically treated laryngeal squamous cell carcinoma (LSCC) patients.

Methods: A multicenter retrospective study with 352 patients was analyzed. A new nomogram that incorporates age, T- and N-classification, and treatment was created.

HT-29 Colon Cancer Cell Electromanipulation and Assessment Based on Their Electrical Properties.

This study proposes a feasible approach for the rapid, sensitive, and label-free identification of cancerous cells based on dielectrophoretic (DEP) manipulation and electrical characterization. In this method, the concentration of target cells at the level of customized microelectrodes via DEP is first determined, followed by an electrical impedance evaluation. The study demonstrates the capacity of the methodology to electrically differentiate HT-29 cancer cells from healthy blood cells based on their impedance spectra.
